    The University of Washington is launching a new augmented and virtual reality research center — funded by Facebook, Google, and Huawei — to accelerate innovation in the field and educate the next generation of researchers and practitioners.

    The $6 million UW Reality Lab, funded with equal contributions from the three initial sponsors, creates one of the world’s first academic centers dedicated to virtual and augmented reality. The new center in the Paul G. Allen School of Computer Science & Engineering and located in Seattle — a national hub of VR activity — will support research and education initiatives with potential to deliver game-changing breakthroughs in the field.

    “Allen School faculty have produced pioneering research in many of the areas that underpin AR and VR technologies, including computer vision, graphics, perception, and machine learning,” said Hank Levy, Allen School director and Wissner-Slivka Chair in Computer Science and Engineering. “Through our partnership with Facebook, Google, and Huawei, the Allen School and UW will be at the forefront of the next great wave of AR and VR innovation — pursuing breakthrough research and educating the next generation of innovators in this exciting and rapidly expanding field.”

    To date, AR and VR applications are making their first steps, mostly focusing on entertainment and games. Yet everyone is interested to find the “killer app” for AR and VR. The goal of the UW Reality Lab is to develop technology to power the next generation of applications that will speak to a wider population. Those diverse ideas range from learning Spanish by seeing objects labeled in your field of view to achieving telepresence by conversing with a remote relative or co-worker as if you were in the same room.

    “We’re seeing some really compelling and high quality AR and VR experiences being built today,” said center co-lead and Allen School professor Steve Seitz. “But, there are still many core research advances needed to move the industry forward — tools for easily creating content, infrastructure solutions for streaming 3D video, and privacy and security safeguards — that university researchers are uniquely positioned to tackle.”

    The UW Reality Lab will bring together an interdisciplinary team of UW faculty, graduate students and undergraduates working in 3D computer vision and perception, object recognition, graphics, game science and education, distributed computing, stream processing, databases, computer architecture, and privacy and security.

    Another key function of the UW Reality Lab will be to educate tomorrow’s AR and VR researchers and workers. The funding will support new courses and access to state-of-the-art labs and infrastructure for UW students to develop new technologies and applications. That includes accessing emerging technologies from the center’s sponsors and allowing those companies to test new ideas in a focused setting with computer science students. An advisory board of luminaries from across the AR and VR community will help the center remain at the forefront of this burgeoning field.

    The UW Reality Lab builds on the Allen School’s established leadership in cutting-edge AR/VR education and research. In one example, the school in 2016 introduced the world’s first augmented reality capstone course, in which students built AR applications using 40 HoloLens units loaned from Microsoft before they were commercially available.

    “Students had fantastic ideas and were able to create amazing AR and VR applications ranging from Holographic Chess to teaching one how to play the piano or cook. This opened our eyes to the potential of investing deeper in development of algorithms and applications for AR and VR,” said center co-lead and Allen School assistant professor Ira Kemelmacher-Shlizerman. “We realized there were so many cool things we could do if only we had more resources, more time and more devices. Given those, we can help bring the world’s AR and VR dreams to life.”

    The UW Reality Lab’s location in Seattle — one of the world’s most active centers for VR and AR innovation — paves the way for unique industry and academic collaborations aimed at achieving new capabilities and offering users seamless experiences.

    “Having an opportunity to be at the leading edge of this industry is really exciting,” said co-lead and Allen School professor Brian Curless. “It’s big, it’s happening now and there’s a lot of research to be done. We’re thrilled to take a leading role in making it all happen.”

    December 19, 2017 [Just now in social media.]

    The University of Washington has joined the Center for Health Organization Transformation (CHOT), a National Science Foundation (NSF) funded Industry-University Cooperative Research Center focused on providing innovative, evidence-based transformational strategies in healthcare.

    The Department of Industrial & Systems Engineering (ISE) and the Department of Health Services (HS) will lead the site. ISE associate professor Christina Mastrangelo will act as director, with ISE research scientist Joe Heim and HS affiliate associate professor Cynthia LeRouge acting as assistant directors.

    Joe Heim and Christina Mastrangelo

    The UW site will receive $250,000 in funding per year in an initial three-year agreement — $100,000 from the NSF and $50,000 from each industry partner.

    3

    CHOT’s driving force is the industry-university partnership, and the University of Washington has partnered with three local health services providers: Carena, a telemedicine provider; Philips Health, a developer of radiology solutions; and Seattle Children’s Hospital, the leading pediatric medical center in the region. Together, industry partners and UW researchers aim to develop strategies that will tackle pressing, real-world healthcare problems.

    With the addition of the UW, CHOT has grown to an eight-university entity. Other CHOT members include Texas A&M University, Penn State University, Georgia Tech, the University of Louisville, Florida Atlantic University, the University of Alabama, and the University of Nottingham. Together, the eight universities have formed partnerships with more than 30 organizations from across the health services sector.

    The UW’s position as the only CHOT member on the west coast provides opportunity to engage with healthcare organizations throughout the Pacific Northwest. By joining CHOT, the UW will be able to take advantage of its position as the regional leader in health services.

    According to Bita Kash, CHOT center director, “CHOT depends on the expertise and leadership that the University of Washington has already been able to provide over the last two years interacting with other CHOT university sites and researchers.” ISE has collaborated with CHOT since 2013, in which time it has conducted research with Carena and Philips Health.

    Industry projects are already underway, and these projects will harness the UW’s expertise in the physical, virtual, economic and social aspects of healthcare strategy and delivery. For example, the UW will be investigating system factors that impact Carena’s direct-to-consumer telehealth service as well as optimizing usage of Philips Health’s MRI equipment.

    The CHOT membership brings benefits to UW students and faculty alike. Undergraduate and graduate students will gain experience in health services research, while faculty will be able to make connections with both the industry partners directly affiliated with UW and those affiliated with the other CHOT sites.

    From U Washington: “UW a leader in supporting Washington’s STEM students”

    Scholar Solomon Muche is studying bioengineering at the UW.Washington State Opportunity Scholarship.

    In an effort to grow the pipeline of Washington students who will graduate and enter high-demand STEM and health care fields, a public-private partnership was initiated in 2011 to support low- and middle-income students as they earn their bachelor’s degrees and enter the workforce.

    Now serving its sixth cohort of students, the Washington State Opportunity Scholarship has helped more than 8,400 students attend the state’s universities and colleges. The University of Washington has the largest number of scholarship recipients — 1,426 — and has seen more than 1,100 scholarship students graduate, also the largest number among the state’s higher-education institutions.

    Additionally, UW Bothell has enrolled 132 scholarship students and UW Tacoma has enrolled 121 students over the program’s six years. In total, 1,679 students receiving the scholarship have attended the UW across all three campuses.

    “The Washington State Opportunity Scholarship represents a deep and abiding commitment by our state to high-quality education resolutions for all of our students, with needed attention to those from low- and middle-income backgrounds,” said Ed Taylor, vice provost and dean of undergraduate academic affairs at the UW. “With the help of clear and dependable opportunities for STEM training, we increase the likelihood that we will generate opportunities for promising young scholars who are supported by an innovative environment that has become a hallmark of the state of Washington.”

    The demographics of this year’s scholarship cohort reflect the growing diversity of the state as well as the UW’s commitment to diversity and access. According to the program’s annual report to the legislature this month, 72 percent are first-generation college students, 73 percent are students of color and 60 percent of new scholars are female. This year’s 1,751 scholars come from 38 of Washington’s 39 counties.

    2
    Scholars Diana Algomeda-Villada, left, and Wilder Garcia are students at UW Tacoma.Washington State Opportunity Scholarship.

    As outlined in a recent Microsoft story, the scholarship program is unique for its public-private partnership design. Under the program, the state matches private donations dollar-for-dollar. By the end of this current school year, students will have received more than $50 million in scholarships. Microsoft is one of the founding partners of the Washington State Opportunity Scholarship, and a number of local companies and private contributions also support the program.

    The need for graduates in science, technology, engineering, mathematics and health care fields is only increasing. A recent TechAlliance report found that at current rates, the state’s colleges and universities will only be able to supply 27 percent of skilled STEM workers needed around the state by 2025.

    As a result, the Washington State Opportunity Scholarship recently announced a move to serve 16,000 scholars by 2025. This program extension of four additional years also offers more support services for scholars, including industry mentorship and a peer leadership program that helps younger students learn in a small group setting.

    Earlier this year, the UW College of Engineering’s Washington State Academic RedShirt (STARS) program received a $2.2 million grant from the Opportunity Expansion Fund, a related program established by the legislature to help Washington universities fund programming that supports students earning high-demand bachelor’s degrees in science, engineering, computer science or STEM education.

    Tags: , , Discovering detrimental leaks by developing “smart” paper that can sense the presence of water, , , Smart paper, U Washington   

    From University of Washington: “‘Smart’ paper can conduct electricity, detect water”

    In cities and large-scale manufacturing plants, a water leak in a complicated network of pipes can take tremendous time and effort to detect, as technicians must disassemble many pieces to locate the problem. The American Water Works Association indicates that nearly a quarter-million water line breaks occur each year in the U.S., costing public water utilities about $2.8 billion annually.

    A University of Washington team wants to simplify the process for discovering detrimental leaks by developing “smart” paper that can sense the presence of water. The paper, laced with conductive nanomaterials, can be employed as a switch, turning on or off an LED light or an alarm system indicating the absence or presence of water.

    The researchers described their discovery in a paper appearing in the November issue of the Journal of Materials Chemistry A.

    “Water sensing is very challenging to do due to the polar nature of water, and what is used now is very expensive and not practical to implement,” said lead author Anthony Dichiara, a UW assistant professor of bioresource science and engineering in the School of Environment and Forest Sciences. “That led to the reason to pursue this work.”

    See slide show of images at the full article.

    Along with Dichiara, a team of UW undergraduate students in the Bioresource Science and Engineering program successfully embedded nanomaterials in paper that can conduct electricity and sense the presence of water. Starting with pulp, they manipulated the wood fibers and carefully mixed in nanomaterials using a standard process for papermaking, but never before used to make sensing papers.

    Discovering that the paper could detect the presence of water came by way of a fortuitous accident. Water droplets fell onto the conductive paper the team had created, causing the LED light indicating conductivity to turn off. Though at first they thought they had ruined the paper, the researchers realized they had instead created a paper that was sensitive to water.

    When water hits the paper, its fibrous cells swell to up to three times their original size. That expansion displaces conductive nanomaterials inside the paper, which in turn disrupts the electrical connections and causes the LED indicator light to turn off.

    This process is fully reversible, and as the paper dries, the conductive network re-forms so the paper can be used multiple times.

    The researchers envision an application in which a sheet of conductive paper with a battery could be placed around a pipe or under a complex network of intersecting pipes in a manufacturing plant. If a pipe leaks, the paper would sense the presence of water, then send an electrical signal wirelessly to a central control center so a technician could quickly locate and repair the leak.

    In addition, the paper is so sensitive that it can also detect trace amounts of water in mixtures of various liquids. This ability to distinguish water from other molecules is particularly valuable for the petroleum and biofuel industries, where water is regarded as an impurity.

    “I believe that for large-scale applications, this is definitely doable,” Dichiara said. “The price for nanomaterials is going to drop, and we’re already using an established papermaking process. You just add what we developed in the right place and time in the process.”

    The nanomaterials added to the paper were engineered in such a way that they can be incorporated during conventional papermaking without having to modify the process. These materials are made of extremely conductive carbon. Because carbon is found in all living things, nearly any natural material can be burned to make charcoal, and then carbon atoms can be extracted to synthesize the materials. The team has experimented with making nanomaterials from banana peels, tree bark and even animal feces.

    They also tried making nanomaterials from wood scraps to show that the entire papermaking process can be completed with cheap, natural materials.

    “Now we have a sustainable process where everything is from pulp and paper, and we can make conductive materials from them,” Dichiara said.

    The paper, stiff and smooth in texture, is a rich black color because of the nanomaterials (carbon from charcoal). The 8-inch disks made in the lab are prototypes; the team hopes to test the process on an industrial-sized papermaking machine next, which will require more nanomaterials and paper pulp.

    Other co-authors are Sheila Goodman, a UW graduate student, and Delong He and Jinbo Bai of Universite Paris-Saclay in France. UW undergraduate students Jimeng Cui, Riley Fitzpatrick, Sydney Fry, Demi Lidorikiotis, Anna Song and Zoie Tisler completed additional lab work.

    Funding for this research came from the U.S. Department of Agriculture’s National Institute of Food and Agriculture, McIntire Stennis project, and from the UW School of Environmental and Forest Sciences.

    One of the worst nightmares for many Pacific Northwest residents is a huge earthquake along the offshore Cascadia Subduction Zone, which would unleash damaging and likely deadly shaking in coastal Washington, Oregon, British Columbia and northern California.

    At depths shallower than 30 km or so, the CSZ is locked by friction while strain slowly builds up as the subduction forces act, until the fault’s frictional strength is exceeded and the rocks slip past each other along the fault in a “megathrust” earthquake. The fault’s frictional properties change with depth, such that immediately below the locked part is a strip (the “Transition Zone”) that slides in “slow slip events” that slip a few cm every dozen months or so. This relieves the plate boundary stresses there, but adds to the stress on the locked part of the fault. Below the transition zone geodetic evidence suggests that the fault slides continuously and silently at long term plate slip rate. From it’s surface trace offshore to a depth of possibly 5 km, all remote from land, observations are few and it remains unknown whether the fault is stuck or slipping silently.

    Great Subduction Zone earthquakes are the largest earthquakes in the world, and are the only source zones that can produce earthquakes greater than M8.5. The CSZ has produced magnitude 9.0 or greater earthquakes in the past, and undoubtedly will in the future.

    Seismologist Kim Olsen of San Diego State University produced this simulation of what slip in a M9 CSZ earthquake might look like.

    The last known megathrust earthquake in the northwest was in January, 1700, just over 300 years ago. Geological evidence indicates that such great earthquakes have occurred at least seven times in the last 3,500 years, a return interval of 400 to 600 years. To learn more about the history of the Cascadia Subduction Zone and the science that led to the discovery of it, delve into land level changes and turbidites created by the CSZ earthquakes. For more about the Cascadia Subduction Zone, visit the USGS webpage discussing this topic.

    The CSZ may be unique among the worlds subduction zones in that it produces very few (if any) earthquakes unambiguously on the plate interface. Coupled with evident occurrence of great megathrust earthquakes, the CSZ must be much more strongly locked than other subduction faults. The geological evidence has led to different interpretrations, moreover, about whether the entire CSZ always ruptures in great M9 earthquakes, or whether smaller M8 or M8.5-sized events also can break parts of the zone in between the full rupture events.

    The last time this happened was in 1700, before seismic instruments were around to record the event. So what will happen when it ruptures next is largely unknown.

    A University of Washington research project, to be presented Oct. 24 at the Geological Society of America’s annual meeting in Seattle, simulates 50 different ways that a magnitude-9.0 earthquake on the Cascadia subduction zone could unfold.

    “There had been just a handful of detailed simulations of a magnitude-9 Cascadia earthquake, and it was hard to know if they were showing the full range,” said Erin Wirth, who led the project as a UW postdoctoral researcher in Earth and space sciences. “With just a few simulations you didn’t know if you were seeing a best-case, a worst-case or an average scenario. This project has really allowed us to be more confident in saying that we’re seeing the full range of possibilities.”

    Off the Oregon and Washington coast, the Juan de Fuca oceanic plate is slowly moving under the North American plate. Geological clues show that it last jolted and unleashed a major earthquake in 1700, and that it does so roughly once every 500 years. It could happen any day.

    Wirth’s project ran simulations using different combinations for three key factors: the epicenter of the earthquake; how far inland the earthquake will rupture; and which sections of the fault will generate the strongest shaking.

    Results show that the intensity of shaking can be less for Seattle if the epicenter is fairly close to beneath the city. From that starting point, seismic waves will radiate away from Seattle, sending the biggest shakes in the direction of travel of the rupture.

    “Surprisingly, Seattle experiences less severe shaking if the epicenter is located just beneath the tip of northwest Washington,” Wirth said. “The reason is because the rupture is propagating away from Seattle, so it’s most affecting sites offshore. But when the epicenter is located pretty far offshore, the rupture travels inland and all of that strong ground shaking piles up on its way to Seattle, to make the shaking in Seattle much stronger.”

    The research effort began by establishing which factors most influence the pattern of ground shaking during a Cascadia earthquake. One, of course, is the epicenter, or more specifically the “hypocenter,” which locates the earthquake’s starting point in three-dimensional space.

    Another factor they found to be important is how far inland the fault slips. A magnitude-9.0 earthquake would likely give way along the whole north-south extent of the subduction zone, but it’s not well known how far east the shake-producing area would extend, approaching the area beneath major cities such as Seattle and Portland.

    The third factor is a new idea relating to a subduction zone’s stickiness. Earthquake researchers have become aware of the importance of “sticky points,” or areas between the plates that can catch and generate more shaking. This is still an area of current research, but comparisons of different seismic stations during the 2010 Chile earthquake and the 2011 Tohoku earthquake show that some parts of the fault released more strong shaking than others.

    Wirth simulated a magnitude-9.0 earthquake, about the middle of the range of estimates for the magnitude of the 1700 earthquake. Her 50 simulations used variables spanning realistic values for the depth of the slip, and had randomly placed hypocenters and sticky points. The high-resolution simulations were run on supercomputers at the Pacific Northwest National Laboratory and the University of Texas, Austin.

    Overall, the results confirm that coastal areas would be hardest hit, and locations in sediment-filled basins like downtown Seattle would shake more than hard, rocky mountaintops. But within that general framework, the picture can vary a lot; depending on the scenario, the intensity of shaking can vary by a factor of 10. But none of the pictures is rosy.

    “We are finding large amplification of ground shaking by the Seattle basin,” said collaborator Art Frankel, a U.S. Geological Survey seismologist and affiliate faculty member at the UW. “The average duration of strong shaking in Seattle is about 100 seconds, about four times as long as from the 2001 Nisqually earthquake.”

    The research was done as part of the M9 Project, a National Science Foundation-funded effort to figure out what a magnitude-9 earthquake might look like in the Pacific Northwest and how people can prepare. Two publications are being reviewed by the USGS, and engineers are already using the simulation results to assess how tall buildings in Seattle might respond to the predicted pattern of shaking.

    As a new employee of the USGS, Wirth will now use geological clues to narrow down the possible earthquake scenarios.

    “We’ve identified what parameters we think are important,” Wirth said. “I think there’s a future in using geologic evidence to constrain these parameters, and maybe improve our estimate of seismic hazard in the Pacific Northwest.”

    Other co-authors are Nasser Marafi, a UW doctoral student in civil and environmental engineering; John Vidale, a former UW professor now at the University of Southern California; and Bill Stephenson with the USGS.

    From University of Washington: “Flexible ‘skin’ can help robots, prosthetics perform everyday tasks by sensing shear force”

    If a robot is sent to disable a roadside bomb — or delicately handle an egg while cooking you an omelet — it needs to be able to sense when objects are slipping out of its grasp.

    Yet to date it’s been difficult or impossible for most robotic and prosthetic hands to accurately sense the vibrations and shear forces that occur, for example, when a finger is sliding along a tabletop or when an object begins to fall.

    Now, engineers from the University of Washington and UCLA have developed a flexible sensor “skin” that can be stretched over any part of a robot’s body or prosthetic to accurately convey information about shear forces and vibration that are critical to successfully grasping and manipulating objects.

    The bio-inspired robot sensor skin, described in a paper published in Sensors and Actuators A: Physical [ScienceDirect], mimics the way a human finger experiences tension and compression as it slides along a surface or distinguishes among different textures. It measures this tactile information with similar precision and sensitivity as human skin, and could vastly improve the ability of robots to perform everything from surgical and industrial procedures to cleaning a kitchen.

    “Robotic and prosthetic hands are really based on visual cues right now — such as, ‘Can I see my hand wrapped around this object?’ or ‘Is it touching this wire?’ But that’s obviously incomplete information,” said senior author Jonathan Posner, a UW professor of mechanical engineering and of chemical engineering.

    “If a robot is going to dismantle an improvised explosive device, it needs to know whether its hand is sliding along a wire or pulling on it. To hold on to a medical instrument, it needs to know if the object is slipping. This all requires the ability to sense shear force, which no other sensor skin has been able to do well,” Posner said.

    Some robots today use fully instrumented fingers, but that sense of “touch” is limited to that appendage and you can’t change its shape or size to accommodate different tasks. The other approach is to wrap a robot appendage in a sensor skin, which provides better design flexibility. But such skins have not yet provided a full range of tactile information.

    “Traditionally, tactile sensor designs have focused on sensing individual modalities: normal forces, shear forces or vibration exclusively. However, dexterous manipulation is a dynamic process that requires a multimodal approach. The fact that our latest skin prototype incorporates all three modalities creates many new possibilities for machine learning-based approaches for advancing robot capabilities,” said co-author and robotics collaborator Veronica Santos, a UCLA associate professor of mechanical and aerospace engineering.

    The new stretchable electronic skin, which was manufactured at the UW’s Washington Nanofabrication Facility, is made from the same silicone rubber used in swimming goggles. The rubber is embedded with tiny serpentine channels — roughly half the width of a human hair — filled with electrically conductive liquid metal that won’t crack or fatigue when the skin is stretched, as solid wires would do.

    When the skin is placed around a robot finger or end effector, these microfluidic channels are strategically placed on either side of where a human fingernail would be.

    As you slide your finger across a surface, one side of your nailbed bulges out while the other side becomes taut under tension. The same thing happens with the robot or prosthetic finger — the microfluidic channels on one side of the nailbed compress while the ones on the other side stretch out.

    When the channel geometry changes, so does the amount of electricity that can flow through them. The research team can measure these differences in electrical resistance and correlate them with the shear forces and vibrations that the robot finger is experiencing.

    “It’s really following the cues of human biology,” said lead author Jianzhu Yin, who recently received his doctorate from the UW in mechanical engineering. “Our electronic skin bulges to one side just like the human finger does and the sensors that measure the shear forces are physically located where the nailbed would be, which results in a sensor that performs with similar performance to human fingers.”

    Placing the sensors away from the part of the finger that’s most likely to make contact makes it easier to distinguish shear forces from the normal “push” forces that also occur when interacting with an object, which has been difficult to do with other sensor skin solutions.

    The research team from the UW College of Engineering and the UCLA Henry Samueli School of Engineering and Applied Science has demonstrated that the physically robust and chemically resistant sensor skin has a high level of precision and sensitivity for light touch applications — opening a door, interacting with a phone, shaking hands, picking up packages, handling objects, among others. Recent experiments have shown that the skin can detect tiny vibrations at 800 times per second, better than human fingers.

    “By mimicking human physiology in a flexible electronic skin, we have achieved a level of sensitivity and precision that’s consistent with human hands, which is an important breakthrough,” Posner said. “The sense of touch is critical for both prosthetic and robotic applications, and that’s what we’re ultimately creating.”

    The research was funded by the National Science Foundation.

    About one quarter of the world’s population suffers from anemia, a disease caused by a concentration deficiency of hemoglobin in red blood cells. To reduce the burden of anemia, health officials need a better picture of the disease’s global impact, an understanding made viable by a portable and affordable way to analyze blood.

    Researchers at the University of Washington developed a device smaller than a toaster that can detect the level of hemoglobin in whole blood samples using optical absorbance. The work is published this week in AIP Advances, from AIP Publishing.

    Hemoglobin is a protein found in red blood cells that transports oxygen throughout the body. As the concentration of hemoglobin decreases, the body becomes starved of oxygen, often resulting in dizziness, fatigue, shortness of breath, and abnormal heart rate.

    Blood analyzers currently on the market measure hemoglobin by chemically rupturing the red blood cells in a sample. This technique requires hands-on expertise to prepare and run a sample, limiting the ability to monitor anemia in many parts of the world.

    “The most exciting aspect to this analyzer is that it uses whole blood and does not require the additional steps and reagents to prepare a sample,” said Nathan Sniadecki, associate professor in mechanical engineering at the University of Washington and one of the authors.

    The device only requires a few drops of blood for analysis.

    “You just run blood into the channel and that’s it,” said Nikita Taparia, a doctoral candidate in Snaidecki’s lab and another author. “It can be used anywhere.”

    The analyzer takes advantage of the optical properties of blood, such as absorption and scattering, to measure hemoglobin concentration. Anemic blood transmits more light compared to normal blood, so the severity of anemia can be measured as a ratio of transmitted to original light intensity.

    To simulate anemia, the researchers diluted blood samples with a buffer solution. The blood analyzer was effective at predicting cases of moderate to severe anemia, defined as less than 10 grams per deciliter of hemoglobin in a sample. The analyzer did not produce any false negative results.

    The optical density of samples did not increase linearly, so a higher concentration of hemoglobin defines the upper limit of detection for the device.

    The primary cause of anemia is iron deficiency, but it can co-occur with other conditions, such as malaria and genetic disorders like sickle cell. Severe anemia can lead to increased maternal and child mortality. It also impairs cognitive and physical development in children.

    “It has been really rewarding to be part of a project from start to finish that produced a device that will really help people,” Taparia said. “This analyzer is meant for people who have disease.”

    The current design is a prototype that could be integrated with other microfluidic devices to analyze whole blood samples in parallel to diagnose anemia and other underlying factors that could contribute to the disease.

    The research received support from a Department of Education GAANN Fellowship and a National Science Foundation Grant.

    Tags: , , Hacking a pressure sensor to track gradual motion along marine faults, U Washington   

    From U Washington: “Hacking a pressure sensor to track gradual motion along marine faults” 

    U Washington

    University of Washington

    September 21, 2017
    Hannah Hickey

    Deep below the ocean’s surface, shielded from satellite signals, the gradual movement of the seafloor — including along faults that can unleash deadly earthquakes and tsunamis — goes largely undetected. As a result, we know distressingly little about motion along the fault that lies just off the Pacific Northwest coast.

    University of Washington oceanographers are working with a local company to develop a simple new technique that could track seafloor movement in earthquake-prone coastal areas. Researchers began testing the approach this summer in central California, and they plan to present initial results in December at the American Geophysical Union’s annual meeting in New Orleans.

    1
    The modified pressure sensor is now being tested at the bottom of Monterey Bay.MBARI/University of Washington

    Their approach uses existing water-pressure sensors to cheaply measure gradual swelling of the seafloor over months to years. If successful, the innovative hack could provide new insight into motion along the Cascadia Subduction Zone and similar faults off Mexico, Chile and Japan. The data could provide clues about what types of earthquakes and tsunamis each fault can generate, where and how often.

    The concept began with a workshop in 2012 that brought together Jerry Paros, the founder of Bellevue-based Paroscientific, Inc., with UW geoscientists. Paros’ company manufactures sensors used to measure pressure at the bottom of the ocean with high precision, which are used by the National Oceanographic and Atmospheric Administration for its tsunami sensors.

    2
    The Paroscientific sensor’s crystal inside this instrument can measure crushing pressures on the seafloor. University of Washington researchers altered the sensor to monitor seismic creep by calibrating its measurements against the pressure inside the silver titanium case.University of Washington

    But an engineering quirk prevents the sensors from measuring the gradual ground motions that build up pressure along earthquake faults. The instruments can measure seafloor pressure, or the weight of water above the sensor, to an extremely precise fraction of a millimeter. But the readings lose accuracy over time, and the error is proportional to the quantity measured. On the ocean floor, where pressures are tens to hundreds of times that on the surface, the readings can change by 10 centimeters (3 inches) per year. In between major earthquakes, this is much more than the seafloor might shift up or down due to tectonic forces.

    “If you want to measure how the seafloor is moving, you don’t want your reading to change by a larger value than the thing that you’re measuring,” said Dana Manalang, an engineer at the UW’s Applied Physics Laboratory who is working on the project.

    Paros proposed an idea that would instead calibrate the pressure sensor against the air pressure inside the metal case that houses the instrument, which is roughly one atmosphere. This would allow existing pressure sensors to autonomously track small bulges and slumps on the seafloor.

    Last year engineers at the UW Applied Physics Laboratory modified an existing Paros pressure sensor. The sensitive quartz crystal that measures the seafloor pressure can now be connected to measure pressure inside its titanium instrument case, with a known pressure and another barometer to check the value. The prototype instrument was attached in mid-June to the Monterey Accelerated Research System, a cabled seafloor observatory that lets researchers communicate directly with the instrument.

    “That chunk of seafloor actually does not move much. We’re looking for a null result,” Manalang said. “If successful, the next step would be to deploy similar instruments in some more geologically active areas.”

    Those areas include the Cascadia Subduction Zone, the fault that could unleash the Really Big One at any time on the Pacific Northwest.

    Geologists studying the small rise and fall of this section of seafloor, around 1 centimeter per year, have instead been forced to develop complicated workarounds.

    “We are trying to find a pattern of which areas are going up and which areas are going down, and how quickly, which can potentially tell us where the subduction zone fault is locked,” said William Wilcock, a UW oceanography professor who holds the Paros endowed chair. “But we can’t yet do that with a conventional pressure sensor.”

    Wilcock and seismologists at Scripps Institution of Oceanography have been monitoring seafloor movement off central Oregon, where the Cascadia Fault displays behavior that suggests it may gradually slip, releasing strain along that section of the fault. Once a year, the partners go to sea with a research ship, deep-sea robot and specialized equipment to calibrate six seafloor pressure sensors. By monitoring exactly how the seafloor has moved in this way from one summer to the next, they can compare sections of the fault and learn which zones are fully locked, building up potentially dangerous energy, and which aren’t.

    “The approach we are using appears to work, but it’s expensive, and you can’t do it very often,” Wilcock said.

    If Paros’ modified sensors can do the job, future work might place a network of them along Cascadia or other subduction zones, in which a seafloor plate plunges beneath a continental plate. Measuring motion along different parts of these faults might answer longstanding questions about how and where a fault ruptures.

    From her Seattle office, Manalang now communicates with the prototype sensor in Monterey and flips the crystal about once each weekday to recalibrate it against the instrument housing pressure. She will flip it less often as the test continues, while remotely monitoring the change in pressure readings.

    “We’re still close to the starting line on this one, and have some initial, really promising results,” Manalang said. Observations so far show that the shift in measurements is predictable, and similar at both ends of the instrument’s range. “We’re at the very beginning of what we hope is a fairly long-term test,” she said.

    If the method proves reliable, future pressure sensors could be programmed to pivot periodically on their own and gather observations over months or years. Precise long-term measurements of water pressure could not only help seismologists, but also researchers who study how sea level changes over decades.

    “If you can make very accurate observations, and routinely, it would interest both the people studying what’s happening beneath and what’s happening above,” Wilcock said. “These data would open up a whole bunch of new studies.”

    The research is funded by Jerry Paros and the University of Washington.

    Tags: Anthropocene epoch, Earth as hybrid planet, Nikolai Kardashev, Non-equilibrium thermodynamics, U Washington   

    From U Washington: “Earth as hybrid planet” 

    U Washington

    University of Washington

    New classification scheme places Anthropocene era in astrobiological context.

    September 6, 2017
    Peter Kelley

    For decades, as astronomers have imagined advanced extraterrestrial civilizations, they categorized such worlds by the amount of energy their inhabitants might conceivably be able to harness and use.

    They sorted the hypothetical worlds into three types according to a scheme named in 1964 for Soviet astronomer Nikolai Kardashev. A Type 1 civilization could manipulate all the energy resources of its home planet (a distant goal yet for Earth) and Type 2 all the energy in its star/planetary system. A super-advanced Type 3 civilization would command the energy of its whole home galaxy. The Kardashev Scale has since become a sort of gold standard for dreaming about possible civilizations beyond Earth.

    Now, a team of researchers including Marina Alberti of the University of Washington has devised a new classification scheme for the evolutionary stages of worlds based on “non-equilibrium thermodynamics” — a planet’s energy flow being out of synch, as the presence of life could cause. The categories range from imagined planets with no atmosphere whatsoever to those with an “agency-dominated biosphere” or even a “technosphere,” reflecting the achievements of a vastly advanced, “energy-intensive technological species.”

    Their paper, Earth as a Hybrid Planet: The Anthropocene in an Evolutionary Astrobiological Context, was published Sept. 6 in the journal Anthropocene. Lead author is Adam Frank, professor of physics and astronomy at the University of Rochester. Alberti is a professor of urban design and planning in the UW College of Built Environments, and director of the college’s Urban Ecology Research Lab.

    The new classification system, the researchers say, is a way of thinking about sustainability on a planetary scale in what is being recognized as the Anthropocene epoch — the geological period of humanity’s significant impact on Earth and its ecosystems. Alberti contends in her research that humans and the urban areas we create are having a strong, planetwide effect on evolution.

    “Our premise is that Earth’s entry into the Anthropocene represents what might, from an astrobiological perspective, be a predictable planetary transition,” they write. “We explore this problem from the perspective of our own solar system and exoplanet studies.

    “In our perspective, the beginning of the Anthropocene can be seen as the onset of the hybridization of the planet — a transitional stage from one class of planetary systems to another.”

    That would be, in their scheme, Earth’s possible transition from Class IV — marked by a thick biosphere and life having some effect on the planet — to the final Class V, where a planet is profoundly affected by the activity of an advanced, energy-intensive species.

    The classification scheme, the researchers write, is based on “the magnitude by which different planetary processes — abiotic, biotic and technologic — generate free energy, i.e. energy that can perform work within the system.”

    Class I represents worlds with no atmosphere at all, such as the planet Mercury and the Earth’s moon.
    Class II planets have a thin atmosphere containing greenhouse gases, but no current life, such as the current states of planets Mars and Venus.
    Class III planets have perhaps a thin biosphere and some biotic activity, but much too little to “affect planetary drivers and alter the evolutionary state of the planet as a whole.” No current examples exist in the solar system, but early Earth may have represented such a world — and possibly early Mars, if life ever flickered there in the distant past.
    Class IV planets have a thick biosphere sustained by photosynthetic activity and life has begun strongly affecting the planetary energy flow.

    Alberti said, “The discovery of seven new exoplanets orbiting the relatively close star TRAPPIST-1 forces us to rethink life on Earth. It opens the possibility to broaden our understanding of coupled system dynamics and lay the foundations to explore a path to long-term sustainability by entering into a cooperative ecological-evolutionary dynamic with the coupled planetary systems.”

    The researchers write, “Our thesis is that the development of long-term sustainable, versions of an energy-intensive civilization must be seen on a continuum of interactions between life and its host planet.”

    The classifications lay the groundwork, they say, for future research on the “co-evolution” of planets along that continuum.

    “Any world hosting a long-lived energy-intensive civilization must share at least some similarities in terms of the thermodynamic properties of the planetary system,” they write. “Understanding these properties, even in the broadest outlines, can help us understand which direction we must aim our efforts in developing a sustainable human civilization.”

    In other words, they added, “If one does not know where one is going, it’s hard to get there.”

    Co-author on the paper is Axel Kleidon of the Max Planck Institute for Biogeochemistry in Jena, Germany.

    From U Washington: Women in STEM – “Undaunted passion: Making STEM education accessible” Tsewone Melaku

    August 16, 2017 [U Wash took their sweet time getting this into social media.]

    Tsewone Melaku discovered engineering in high school through a UW mentorship program. Now a UW student majoring in HCDE [Human Centered Design & Engineering], she is aligning her interests in engineering with her passion to make STEM education accessible to underrepresented high school students.

    Melaku benefited from many of the same UW college access programs in which she now holds leadership roles, such as the Dream Project and the Women’s Center Making Connections program. She shares with us why it’s important to prioritize social justice issues and how she balances volunteering with her engineering studies.

    What led you to the UW?

    I attended high school here in Seattle, first at Ingraham and then at Chief Sealth. I struggled with math during my sophomore year to the point that I nearly failed. A friend was involved with Making Connections, a college readiness program offered through the UW Women’s Center. The program prepares Seattle-area high school girls from low-income communities for success in STEM fields in college. It offers everything from one-on-one tutoring and mentoring to college tours, job shadowing opportunities and college application workshops.

    I got involved with Making Connections because I needed a tutor, but it opened my eyes to so much more! I’m the first in my family to go to college; my parents are from Ethiopia, and the higher education system here was completely unfamiliar to us. After Making Connections, I sought out all the admissions support programs I could. I passed my math class and attended Young, Gifted and Black, a UW conference on social consciousness, cultural awareness and the importance of higher education for Black high school students. I signed up for the Dream Project, a program that partners UW students with first-generation and underrepresented high school students to assist in the college admissions process. I also joined UW’s Young Executives of Color program, certain that I’d major in business.

    Why did you decide to study HCDE?

    I first learned about HCDE through a Making Connections networking event, where a panel of Seattle-area women engineers talked to us about their careers. One woman — an employee at Boeing — was an HCDE alumna. I’d never heard of HCDE, but as she described it, I just kept thinking how cool it sounded. HCDE focuses on end users; it’s a field of engineering that’s all about helping people, and that really aligned with my personal interests.

    Not long after enrolling at the UW, I switched from being a pre-business major to majoring in HCDE. It’s been a great fit. I love the way it’s trained me to think creatively and solve problems.

    Tell us more about how HCDE and your academic goals overlap with your interests in creating awareness, access and exposure to opportunities for underrepresented high school students.

    I want to use my engineering background to help transform education, so I’m also minoring in the UW’s Education, Learning & Society program. My research interests involve the lack of diversity in higher education, particularly in STEM. I want to figure out ways to create better technology — and technical literacy — for underserved K-12 classrooms. There are huge gaps between technology, access and underrepresented communities. I hope to apply HCDE’s approach to user-centered problem solving and design to create technologies that meet the needs of low-income and underserved students.

    I want to put my degree to work after graduating, but I also want to go to graduate school and study human-computer interaction. My ultimate goal is a Ph.D. in engineering education.

    You continue to be involved with Making Connections and the Dream Project as an engineering student. Why?

    Making Connections is my second family, and I help anytime I can. I want kids to believe that higher education is an option, even if it seems impossible. I’ve been there; I know how tough it can be when you’re fifteen and asked to think about your college aspirations, yet the idea of going to college seems like something beyond your world. If I can share my experiences and skills in ways that help high schoolers see themselves as part of this world, then count me in. Especially for girls of color. If we want girls of color to pursue STEM, they need to see women of color being successful in STEM fields.

    I got involved with the Dream Project primarily to help transform it. I valued what the program was trying to do but from my high school experience, I saw ways it could be improved. I was invited to join the Dream Project’s leadership team and teach UW students how to be mentors in high schools after serving as a mentor myself. We’ve reshaped the course curriculum to include — and prioritize — topics like power, privilege, oppression, racism and social awareness. Many of the Dream Project’s student mentors are white or come from privileged backgrounds, and most of the high school students they’re mentoring aren’t, and we felt that it was crucial to overhaul our training practices. We’ve also updated the program’s mission statement and introduced racial equity workshops for leaders and mentors.

    You’re also involved with the UW chapter of National Society of Black Engineers (NSBE) and Women in Science & Engineering (WiSE). Tell us about your roles with these organizations.

    I started working with WiSE this summer as the program assistant for WiSE UP BRIDGE, a first-year academic program for women engineering students. Last year, I served as UW NSBE’s Pre-College Initiative (PCI) Chair and am now serving as the regional PCI Chair. In this role, I work with Black high school students who want to pursue engineering in college. This year we’ll be starting two NSBE Jr. high school chapters in Seattle! In addition to helping them and the other UW chapter leaders, I’ll also be planning the regional PCI conference for NSBE.

    “I want kids to believe that higher education is an option, even if it seems impossible,” says Melaku, who mentors high school students through access programs like Making Connections at the UW Women’s Center. Photo courtesy of the UW Women’s Center.

    How do you balance your engineering studies with your commitments to UW access programs?

    I’m involved in a lot of campus activities, but they’re activities that I’m passionate about. I never feel like, “Oh great, I have to go do X.” It’s always more like, “Cool, I get to go do X.” I try to make time for the things that make me happy. I’m fortunate that engineering is one of those things. Helping people makes me happy, and through HCDE I’m learning all sorts of new ways to help.

    I wanted to be an engineer to prove that I could do it and to show other Black girls that they could, too. Being an engineering student — as well as a mentor, teacher and advocate on campus — is a lot of work, but it’s work that I care about and that I want to do. That makes a huge difference, I think.
