  • Stopping The Downward Spiral – Philadelphia Sports Nation

    Stopping The Downward Spiral – Philadelphia Sports Nation

    [ad_1]

    NCAA Football is Once Again a Philly Autumn Obsession.
    But Is the Local Feel Fading Away?

    Suppose you haven’t gotten an opportunity to take in some great Pennsylvania High School Football yet this fall. In that case,  you still have plenty of time to enjoy a Friday night frenzy or Saturday spectacular at many Philadelphia area high school fields or stadiums.

    You may even get an opportunity to see a 4th and short trademarked Philadelphia bulldozing, pile-driving-tush push — but not from the Eagles (at least not until Sunday).


    For most of us, fall plans of leaf raking and errand running must be worked on Saturday around the national obsession of college football.

    However, seeing some of the nation’s marquee matchups is proving more difficult in the Philadelphia area each year.

    Temple Football, the preeminent Football Program in Philadelphia dating back to 1894 and once influenced by the great Pop Warner, hasn’t gone to a bowl game since 2019 and hasn’t won one since 2017.

    Between 1990 and 2009, Temple Football didn’t have a winning season. Instead, it held on to the promise of a newly constructed stadium in Philadelphia, which has not yet happened.

    LaSalle Football

    LaSalle College and then LaSalle University — who developed a football program during the US Depression era in 1931 until it was discontinued in 2007 due to funding issues. From 1931 until 2007, the football program had only seven winning seasons.

    We’ll have to wait to see if the beginnings of a resurgence in LaSalle’s athletic programs beginning in 2025 will include a return to football.

    Villanova Football

    Perhaps Philadelphia’s saving grace in football lies in its suburbs. Villanova, with a combined record of 647–495–41 (a winning percentage of .564), a legacy since 1894, and one claimed National Championship in 2009. Or the University of Delaware — with its six Division I FCS National Titles, 24 playoff appearances, and 17 Conference Titles.

    Penn Football

    Sitting snugly on the University of Penn campus is one hundred thirty-year-old Franklin Field, whose Gilded-Age Era exterior facade of Weightman Hall has seen six of Penn’s seven national championships, last won in 1924.

    The Eagles beat the Packers in 1960, and the Philadelphia Stars won a USFL title in 1984. It is the oldest college football stadium still in use today.


    The Philadelphia region’s PIAA already boasts one of the best high school football programs in the country.
    Its surrounding PA suburbs deserve the same great experience on Saturday as on Friday.

  • The truth is out there. This astrophysicist is helping to find it using science

    The truth is out there. This astrophysicist is helping to find it using science

    [ad_1]

    Newswise — Capture good, useful data and University of Delaware astrophysicist Federica Bianco will dig deep to help analyze it. It’s what she does with great expertise as a scientist and associate professor of physics and astronomy and it’s a big reason why she was among the 16 people selected to serve on a NASA-appointed panel studying Unidentified Anomalous Phenomena (UAP).

    UAP is the official term now applied to what many used to call Unidentified Flying Objects (UFOs), things spotted in the sky that could not be correlated with an airplane, satellite or some other known aerial phenomenon. The new term includes all manner of anomalous phenomena — whether detected in the air, in space, even under the ocean.

    NASA says UAP are of interest for reasons including national security and air safety. Access to extensive data sets are required to verify or explain observations and the panel has focused on what data could be collected to scientifically discern the nature of UAP.  

    But there has been precious little useful data to go on, as the panel reported in its four-hour publicly accessible meeting on May 31. Now the panel has released its final report.

    During a media briefing on Thursday, Sept. 14, astrophysicist David Spergel, who chaired the independent study panel, was clear.

    “It is essential to clarify that we find no evidence that UAP are extraterrestrial in origin,” he said. “Most events are explainable as planes, balloons, drones or weather phenomena.”

    A small fraction of reports are anomalous, however. So far, for lack of adequate data, scientists cannot explain them.

    “If you see something, collect high-quality data on it,” Spergel said. “Then we can learn.”

    Theories and conspiracy theories often swirl after reported sightings of such anomalies. Images captured on smart phones or other video devices can be impressive and even seem persuasive at a glance.

    Scientists, though, rely on data and bring careful, rigorous processes to the questions they consider.

    “There’s a lot of folklore out there,” said NASA Administrator Bill Nelson. “We want to shift from sensationalism to science.”

    To that end, NASA now has appointed a director of UAP Research, said Nicola Fox, the head of NASA’s Science Mission Directorate.

    Bianco brought high-level data analysis skills and expertise in astrophysics to the interdisciplinary panel, which also included other experts in the scientific, aeronautics and data analytics communities.

    “The reports we have cannot be studied scientifically,” Bianco said. “That’s not a dismissal of people’s experiences. It just doesn’t rise to the level of evidence of extraordinary phenomena. If people see things in the sky that they can’t explain, that doesn’t mean there was a phenomenon in the sky. But with the capabilities they have for observation, it is not explainable by anything they know.”

    This is exactly what astrophysicists investigate, she said. If someone says they saw something in the sky that was brightening up and then dimming and they think it must be a new kind of star, she will have a lot of questions.

    “If they come to me and tell me what they saw, first I want to go and measure it quantitatively,” Bianco said. “Where is it? How much does it brighten? What is the color that tells me about the physics? Are these characteristics something I’ve never seen? Is it something the person has perceived correctly?”

    The questions examined by the panel certainly fall within NASA’s wheelhouse. Exploring space and the atmosphere is central to all NASA does. And while NASA is always looking for signs of life elsewhere in the universe, it does not actively search for UAPs. NASA has said it has found no credible evidence of extraterrestrial life and there is no evidence that UAPs are extraterrestrial.

    The UAP study panel was led by Spergel, president of the Simons Foundation in New York City and previously the chair of the astrophysics department at Princeton University in Princeton, New Jersey. Daniel Evans, assistant deputy associate administrator for research at NASA’s Science Mission Directorate, served as the NASA official responsible for orchestrating the study.

    Bianco has known Spergel for several years and was glad to join the study.

    “I like interdisciplinary groups and the composition of the panel was so intriguing,” she said. “And aliens, right? That’s an interesting thing to think about and to work on. So yeah, I didn’t hesitate much before agreeing to that.”

    Public interest has been high, too. And recent Congressional hearings have drawn more attention to the issue of UAPs. Some interest has carried sharp political barbs, with accusations that NASA and several U.S. government agencies are hiding important evidence of extraterrestrial life, including recovered parts of alien spacecraft and even live aliens themselves.

    “Really, none of the eyewitness testimony — even those by the military that we have seen — has associated data that is of good enough quality,” Bianco said. “If the videos were shot by people’s phones, what were the lighting conditions? How sensitive is the instrument? If you cannot say these things, you cannot know quantitatively. When we were able to do that — in a couple of observations with multiple sensors — in fact, the characteristics were not unique.”

    The data available now are mostly of limited value.

    “The current status of data is inconsistent, largely incomplete and not systematically retrievable,” she said during the panel broadcast on May 31. “That causes problems in the automation of analysis. Machine learning and artificial intelligence cannot be applied until the data meets that standard. Organized repositories are needed.”

    In addition, the data must be collected by calibrated sensors, with information about the brands, characteristics, instrument sensitivity, circumstances, locations and the condition of the sensors. At the time of data collection, she said.

    Bianco finds the quest for useful data essential, but recognizes that not everyone agrees with the need for facts. Some will never accept that their beliefs, based on something other than sound data, may be incorrect.

    “I could spend my life trying to convince some people — and they are clearly not my target audience,” she said.

    Those who think the scientists on the panel are there simply to give plausibility to a greater government cover-up may not really understand the scientist’s quest for knowledge and disseminating that knowledge.

    “As a scientist, if I find evidence of extraterrestrial life, I have not only an obligation to publish the findings but — while there is no board that requires it — spiritually, I have taken an oath to adhere to the truth and propagate the truth that I find. That’s my job,” she said.

    “I don’t work for the government. I understand the government may have security issues that I don’t understand. But I’m a scientist. If this panel showed me evidence of extraterrestrial life, I’d be writing about it.”

    Among Bianco’s suggestions is a crowd-sourcing application that allows people to submit data about things they have seen and allows others to examine and assess that data. It could include camera information, audio, pixels, resolutions, sensitivity of the instrument and the wavelengths it captures.

    “Part of the problem is that if you really want to look at this data in context, you need all of this information,” she said. “One gets a blurry picture, another gets a sound recording and another gets a photo but doesn’t know why the colors look the way they look.”

    Crowd-sourcing projects have their own set of challenges, but she sees potential value for those who want to understand and participate in the quest in some way.

    “You have three types of audiences — people who care, people who don’t care enough to do the work or be active, but can listen to you, and people who are adversarial,” she said. “It might be more satisfying to fight a battle with the adversarial, but it’s not most productive. There are people who have completely bought into the idea that NASA is hiding aliens and is part of some dark forces that sell a lie for reasons I don’t know. That’s not my audience, but they are kind of dominating the discussion.”

    She likes the idea of an app that gives people information about things that exist in the sky and allows them to submit data from their own devices.

    “It could help people become part of this conversation,” she said. “It would help us communicate the understanding we have and what the process looks like.”

    Panelists talked with many agencies to explore the way they collect data, curate data and retain data.

    The Federal Aviation Administration, for example, can tell you that about 880,000 small drones are registered in the United States and thousands are operated on a daily basis. Almost 100 weather stations release balloons on a daily basis, with requirements on how they report timing and tracking data.

    While some may be convinced that what they saw must have been extraterrestrial, scientists don’t start there.

    “I can’t just take your word,” she said. “That’s not how we make decisions. We make decisions based — traditionally and aspirationally — on evidence and fact, not the hunches and feelings of individuals.

    “We have to start from the skeptical point of view. We take the scientific approach, where I first falsify the most unusual explanation and try to explain things in ways that are usual. We have hypotheses and we rule them out. What is left is what we currently believe. Our current understanding of the physical world comes from ruling things out until the things we have found no longer fit the better data that we now have.”

    Any alternate route should be considered with great skepticism.

    “If you’re trying to actively collect exceptional and specific pieces of evidence that support your ideas but don’t look at the larger context, you are trying to make a name for yourself,” she said. “That is not the correct scientific approach…. I would not have been on that panel.”

    Among Bianco’s research interests are technosignatures, which are defined as any detectable sign of extant or extinct life. They are part of UAP studies because they are a sign of technology that can be used to infer the existence of civilizations elsewhere in the universe —including large orbiting structures, atmospheric pollution, narrow-band radio signals or pulsed lasers.

    The panelists started their work on Oct. 24, 2022. All panelists had to submit financial disclosures and have a comprehensive government ethics briefing. Each was appointed in accordance with the Federal Advisory Committee Act, ensuring independent and objective advice.

    With its final report, the panel now has mapped out how data gathered by civilian government entities, commercial data and data from other sources can potentially be analyzed to shed light on UAPs. The study focused solely on unclassified data.

  • When Majority Men Respect Minority Women, Groups Communicate Better: A Neurological Exploration

    When Majority Men Respect Minority Women, Groups Communicate Better: A Neurological Exploration

    [ad_1]

    Newswise — Kyle Emich, a professor of management at the Alfred Lerner College of Business and Economics, along with Rachel Amey and Chad Forbes, then with UD’s Psychology and Brain Sciences Department, were searching for clues about why women’s knowledge often gets ignored in the workplace and how to improve the situation. 

    Drawing on both a problem-solving group exercise and measurements of brain activity, their findings, now published by the journal Small Group Research, illustrate ways stereotypes and attitudes can stifle the benefits of diversity efforts. At the same time, the study also offers hope for solutions. 

    While women are often urged to fight for status, a key takeaway Emich and his colleagues highlighted from their research was that the onus should actually be placed on high-status men to respect and accept women’s expertise. 

    At the root of their research is the concept of diversity. It’s often touted not just as basic fairness, but a way to benefit companies or other organizations. People with different backgrounds and experiences, the reasoning goes, can offer fresh perspectives and a more complete view of the world that makes a team stronger. 

    It only works, though, if they not only share those fresh perspectives with the team, but the team listens. 

    Previous research shows that this is often not the case — people in minority positions, like a woman on an all-male team, are reluctant to go against the group by sharing knowledge that contradicts the narrative. 

    Emich and his collaborators looked for evidence of differing levels of respect for men and women, how that affects the group, and how attitudes shape respect for women. 

    Attitudes, diversity and their effects on a group can be hard to measure. But the researchers developed a novel way to do it, by measuring team members’ brain activity as they collaborated on solving a problem with a clear answer: a murder mystery.  

    How the study worked

    The researchers divided student volunteers into teams of three, always with a gender minority. Some teams were made up of two men and one woman, and some had two women and one man. In each case, the minority group member had clues key to solving the case, so to be effective the group had to draw on all its members’ knowledge and work together. 

    In a twist, the experimenters also hooked up participants to an EEG monitor so they could see how their brains were functioning as they participated in the group activity. The researchers had a theory: that men who were approach-oriented (focused on a positive goal like solving the murder), would be more inclusive than men who were avoidance-oriented (focused on a negative goal like staying away from risk).   

    “We just thought it would be a good application, because most (EEG) studies are either at the individual level or with only two people,” Emich said. “They’re not in actual interacting teams.” 

    With this approach, they didn’t have to rely on asking subjects to imagine being in the minority — they could put them in that position directly. 

    What they found

    Even though all the groups were diverse, it turned out that the teams made up of two men and one woman were less effective. 

    These women faced a double burden. First, women often struggle to speak up when they are in the minority. Emich and his fellow researchers also found that the more the minority women on these teams shared their unique information, key to solving the case, the less respect they got from their team.  

    “They kind of liked her better if she just sat there and was quiet, as opposed to trying to get into the discussion,” Emich said. 

    On teams with majority women, the man’s input was more valued, so these teams were more effective as they shared information to solve the problem. 

    Assessing the EEG readings gave more insight into men’s mental states. The men who did better at including women’s input were, in fact, those whose brain activity indicated their mindset was more approach-oriented, set on solving the problem rather than avoiding risk. 

    On the flip side, whether the women in the majority on their teams were more approach- or avoidance-oriented, as measured by the EEG, “they were sort of accepting the man’s information into their team,” Emich said. “And then the team ended up doing better.” 

    What does this mean?

    The findings, Emich and his team said, confirm the idea that a lack of respect for minorities undermines the benefit of diversity. They also argue that while the burden is often put on women to make sure they have a voice, men in power should also bear this responsibility. 

    Women are told, “You need to lean in, or you need to break the glass ceiling,” Emich said. “… And what we’re saying here is the onus is really on the men, because they have the power, right? So it’s difficult for the women in these teams to come out and kind of take over the team conversation, because they don’t have the power or status to do that.” 

    He’s not arguing that women shouldn’t assert their rights or “lean in,” but that to make real change, men (or people in power, generally) also have a responsibility to make space for minority perspectives. 

    The “approach” or “avoidance” mindsets they studied, Emich said, can be altered. That is, they aren’t an unavoidable part of someone’s personality. It’s not a matter of finding all the avoidance-oriented men in your office and banning them from teams. Rather, these terms describe a person’s motivation in a given moment, and that motivation can change. 

    In an avoidance mindset, Emich explained, people are worried about protecting themselves and staying away from things that might be dangerous. In business oriented, decision-making groups, unique information is seen as being risky. Adding to that, women are generally seen as lower status, he said, so men see the unique information they offer as being extra risky. 

    This is an outlook that can be changed with training and experience, Emich said. Responsibility falls on the group leader to “make the environment feel a little bit safer for people.” That comes both through the words leaders say and the actions they model. 

    Overall, “I think what this [research] does is it helps to highlight why we see this broad effect that lots of people have observed about women’s information not being listened to,” Emich said.

    Juneteenth: A platform for critical conversations about race and time to honor the struggle for justice and equality

    [ad_1]

    Kathryn Benjamin Golden, assistant professor of Africana studies at the University of Delaware, is available to comment on stories about Juneteenth.

    Golden says the holiday “can be used as a platform for critical conversations about race and the legacies of racial slavery, but also the legacies of Black people’s tremendous resistance across time. It is about an ongoing struggle but also honoring that continued movement to create real justice and equality in this country.”

    She shared her thoughts in an article on UD’s news site.

    “When we look at and listen to Black people’s histories and perspectives, we realize that no, independence doesn’t come on July 4. It only comes for some. It doesn’t come for all,” Golden said. “And so how can we really think about the true meaning of freedom? It means looking at the most oppressed and suppressed and marginalized of us and really listening to those historical and present voices and perspectives.”

  • Analog Mixed-Signal and Photonic Integrated Circuits expert presenting at ISSCC and OFC

    Analog Mixed-Signal and Photonic Integrated Circuits expert presenting at ISSCC and OFC

    [ad_1]

    Newswise — Vishal Saxena, associate professor in the University of Delaware’s College of Engineering, will be presenting work by his Analog Mixed-Signal and Photonic Integrated Circuits (AMPIC) lab at the prestigious IEEE International Solid-State Circuits Conference (ISSCC), which takes place in San Francisco from Feb 19-23, 2023. At the “Ideas for The Future” session (held on Tuesday, Feb 21 from 10:15 AM-12:00 PM PST) Saxena and Ph.D. candidate Md Jubayer Shawon will present “A Silicon Photonic Reconfigurable Optical AnalogProcessor (SiROAP) with a 4×4 Optical Mesh” (Presentation ID: 13.6).

    This talk will include experimental results for a reconfigurable processor, also known as an optical field-programmable gate array (FPGA), that contains hundreds of optical components integrated into a single chip. This type of technology has the potential to support a wide array of applications, including flexible wireless systems, transport of wideband wireless signals on lightweight optical fibers, data center infrastructure, biochemical sensors, and optical quantum computer building blocks.ISSCC is also known as the Olympics of chip design and features breakthrough results from fabricated chips from academic and industry research labs.

    This showcases an interest in large-scale photonics in mainstream electronics, which can potentially chart the course for growth in the semiconductor industry beyond Moore’s Law. The goal of the AMPIC lab, directed by Saxena and housed in the Department of Electrical and Computer Engineering, is to use complex electronic chips to envision entirely new architectures that alleviate long-standing challenges in electronics and open new avenues through the integration of optics. The lab’s research is supported by Young Faculty awards from the National Science Foundation, the AirForce, and the Defense Advanced Research Projects Agency (DARPA).

    Penguins, Robots, The Ocean and more

    [ad_1]

    Newswise — Fieldwork in Antarctica is tricky, just ask University of Delaware scientist Matthew Breece. There is the 10-day trek to get there from Delaware, which includes a sometimes stomach-revolting four-day sail through Drake Passage, heavy research equipment to manage, limits on what you can pack. The temperatures are cool, averaging just above freezing at around 36 degrees Fahrenheit in the austral summer from October to February. Weather can change rapidly, too, relegating researchers indoors when conditions are poor and making for very long days in the field when conditions are pristine.

    But if you ask a scientist…or student…if the effort is worth it, the answer is a resounding YES!

    Marine biology students at Caesar Rodney High School in Camden, Delaware, got a firsthand look at what it’s like to conduct field research on penguins in Antarctica on Tuesday, Jan. 24, during a live video call with Matthew Breece, a research scientist in marine science and policy at the University of Delaware.

    “It’s fun, but also a lot of hard work,” said Breece, who guided the nearly 50 students through a virtual tour of Palmer Station, a United States research station situated on Anvers Island, Antarctica.

    Breece showed the students glaciers, laboratory experiments, research equipment and common areas, like the library, and shared stories and answered questions about living among wildlife including penguins, whales and seals. 

    “Wildlife have the right of way here,” said Breece, explaining how researchers were scrambling over rocks to get to their research vessels earlier in the week, while a crab-eater seal sunned itself on the boat dock. Gentoo penguins can swim 22 miles per hour, which is faster than the research boats can go, while Adélie penguins can only swim 10-12 mph.

    Breece and his colleagues are examining the feeding habits and predator-prey interactions of Adélie and Gentoo penguins in the region using an autonomous underwater vehicle (AUV). The AUV, called a REMUS, is equipped with a high-resolution echosounder that uses sonar to collect data about food resources that are available to marine animals in Palmer Deep Canyon on the West Antarctic Peninsula.

    Besides hearing from Breece, students also saw dramatic photographs from Antarctica and scientific charts used in the research.

    The new echosounder gives researchers a birds-eye view of what’s for lunch in the water. It was developed by Mark Moline, Maxwell P. and Mildred H. Harrington Professor of Marine Studies at UD and principal investigator on the project, and project co-PIs Kelly Benoit-Bird, senior scientist at Monterey Bay Aquarium Research Institute and Megan Cimino, assistant researcher at the Institute of Marine Sciences and assistant adjunct professor of ocean sciences at the University of California, Santa Cruz.

    “We switched to shorter wavelength frequencies to look at smaller things,” said Moline. “So, not only looking at the oceanography, but also the high-resolution food distribution of krill, copepods, fish and the species that eat them, like penguins.”

    The UD work complements the National Science Foundation’s ongoing Palmer Station Long-Term Ecological Research (LTER) study related to penguin population sizes and foraging ranges. The seabird component of the Palmer LTER research is led by Cimino, a UD alumna.

    Cimino has a second project with Carlos Moffat, a UD coastal physical oceanographer who also is in Antarctica serving as chief scientist of the Palmer LTER program, which has been collecting long-term ecological data for over 30 years. Collaborating institutions on the broader Palmer LTER study, led by Rutgers University and the Virginia Institute of Marine Science (VIMS), include researchers from UD, University of Virginia, Woods Hole Oceanographic Institution, University of Colorado, and University of California, Santa Cruz.

    Moffat also is conducting physical oceanography work as part of his NSF CAREER award to understand the dynamics of melting glaciers and how that impacts the ocean circulation and properties, such as salinity and temperature of the coastal ocean.

    “As the atmosphere is warming in this region of Antarctica, sea ice is decreasing and more glaciers are melting from the coast, physically changing the environment marine organisms are living in,” said Moffat. “One big question is what this means long term for marine organisms that live in these places, such as penguins, whales, seals and other wildlife. I see my contribution as trying to help them understand how the physical environment impacts the entire ecosystem.”

    From Antarctica to Delaware

    Lessons learned in Antarctica can help shed light on uncertainties about how sea level rise will evolve in other parts of the world, too. For instance, Delaware is a low-lying state with no area of the state more than eight miles from tidal waters. It is considered a big hotspot of sea level rise along the U.S. East Coast. And while sea levels are increasing on average around the world, due to ocean warming and melting ice from the continents, the distribution of sea level is very uneven. 

    “To understand what is going to happen in the future, we need to understand why sea levels are increasing and how it’s going to change over time,” said Moffat. “Antarctica is a good place to study this because change is happening very rapidly.”

    For most of the 20th century, the Palmer Station region was considered the fastest changing region in the southern hemisphere, while the Weddell Sea, which is located just around the corner of the Antarctic peninsula, had not changed as much. Over the last few years, researchers have begun to wonder whether the Weddell Sea has any influence on the West Antarctic Peninsula region or whether the regions are changing independently.

    To better understand these processes, Moffat’s team deployed two AUVs called gliders to sample the circulation close to the coast along the Antarctic peninsula, which is heavily influenced by the melting of glaciers. He and his students recovered oceanographic moorings that have been capturing data, such as water circulation currents, temperature and salinity, since early 2022. This is part of the West Antarctic Peninsula that has never been sampled before, so the team is eager to analyze the data.

    “I am particularly excited about the glider measurements, which I plan to add to my dissertation,” said Frederike (Rikki) Benz, a doctoral student in the Moffat lab. “It is especially interesting to be involved in the whole process from preparing, shipping and deploying to publishing.”

    Classrooms beyond campus

    For students, field research offers the opportunity for hands-on experience with sophisticated research instruments, data collection and analysis, troubleshooting and networking with researchers from other institutions. Sometimes those activities occur in remote regions of the world — like Antarctica.

    “The rarity of this experience comes with a sense of humility and responsibility to not take any moment for granted, a responsibility to ensure more opportunities are available for future students and scientists,” said Evan Quinter, who is pursuing a master’s degree in physical ocean science and engineering in the Moffat Lab.

    At Caesar Rodney High School, marine biology teachers Cristine Taylor and Sandra Ramsdell have just begun covering marine animals with their students. It is a fitting coincidence that made the live call with UD researchers both timely and meaningful.

    “Spending a day in class speaking with researchers was an awesome experience for our students,” said Taylor. “We are trying to encourage them to look at everything that goes into marine careers. Not every person is a marine biologist, there are computer scientists and engineers, ship captains and crew, and so many more people who can work in marine research.”

    Crime expert: Mass shootings show Asian Americans’ vulnerability to inter- and intra-racial violence

    [ad_1]

    University of Delaware professor Ivan Sun can comment on the recent mass shootings in California, including the Jan. 21 attack that took the lives of 11 people and left Asian American communities reeling just as they were celebrating the start of the Lunar New Year. 

    Sun, who studies crime and justice in Asian societies, said the following about the shootings:

    – “They are shocking as Asian Americans’ involvement in violent offending is low – whereas their victimization is high, particularly during the pandemic – and seniors in general are less likely to engage in violent crime.”

    – “They are exceptional events, signaling Asian Americans’ vulnerability to both inter- and intra-racial violence.”

  • The TuFF Age

    The TuFF Age

    [ad_1]

    Newswise — TuFF — Tailored Universal Feedstock for Forming — is a strong, highly aligned, short-fiber composite material that can be made from many fiber and resin combinations. Created at the University of Delaware’s Center for Composite Materials (CCM), it can be stamped into complex shapes, just like sheet metal, and features high-performance and stretchability up to 40%.

    Since its introduction, CCM researchers have explored applications for TuFF, from materials for repairing our nation’s pipelines to uses in flying taxis of the future.

    Now, armed with $13.5 million in funding from the U.S. Air Force, UD mechanical engineers and co-principal investigators Suresh Advani and Erik Thostenson along with industry collaborators Composites Automation and Maher and Associates are working on ways to improve manufacturing methods for TuFF. 

    “I am really excited at the opportunity to mature the TuFF pre-pregging process and demonstrate high-throughput composite thermoforming for Air Force relevant components,” said David Simone of the U.S. Air Force.

    The goal is to enable lighter-weight composites to become cost-competitive with aluminum for creating small parts found in air vehicles.

    Advani explained that when it comes to making aircraft materials more cost-efficient, reducing a material’s weight even a mere kilogram, just 2.2. pounds, will reduce fuel consumption and emissions and can result in thousands of dollars in savings over time. 

    This is because aircraft are heavy. A Boeing 747, for example, weighs a whopping 404,600 pounds. A B2 Stealth Bomber in the U.S. Air Force, meanwhile, tips the scale at over 43,000 pounds.

    “In general, the aerospace industry wants to reduce weight and replace metals,” said Advani, George W. Laird Professor of Mechanical Engineering. TuFF is a good option because the material can achieve properties equivalent to the best continuous fiber composites used in aerospace applications. 

    Advancing TuFF thermosets

    Until now, most of the work around TuFF has focused on thermoplastic composite materials that melt when heated, becoming soft and pliable, which is useful for forming. By contrast, TuFF thermosets have a higher temperature threshold, making them useful for aerospace applications. But TuFF thermosets have manufacturing challenges, too, including the long manufacturing times necessary to make a part. 

    In this new project, Thostenson and Advani will work on ways to improve the viability of thermoset TuFF composites. To start, the researchers will characterize the starting materials’ mechanical properties to understand how to make TuFF thermosets reliably and consistently. The research team will explore whether they can make the material in a new way, using thin resin films and liquid resins. They will test the limits of how the material forms and behaves under pressure and temperature, too.

    “How does it stretch during forming in a mold? What shapes can we make? When does it tear or thin or develop voids that can compromise material integrity?” said Advani.

    Having a database for such properties and behaviors will be useful in understanding TuFF material capabilities and limits, and to inform efforts to model and design parts with TuFF.

    Thostenson, professor of mechanical engineering, is an expert in structural health monitoring of materials. He will advance ways to embed sensor technology into TuFF thermosets. This would allow the researchers to see from the inside how the material is forming and curing during its manufacture, in hopes of being able to gauge—and improve— the material’s damage tolerance. 

    It’s intricate work. To give an idea of scale, a single layer of TuFF material is approximately 100 microns thick, about the diameter of the average human hair. The carbon-nanotube sensors Thostenson plans to integrate into the material are smaller still—one billionth the width of a human hair. 

    “This would allow us to do health monitoring for the materials and parts during service life, but you could also imagine using sensor technology to detect a defect during manufacturing,” said Thostenson. 

    While it remains to be seen whether this is possible, Thostenson said having this ability could result in real cost savings for manufacturing methods, where real-time knowledge of how a material is curing could help the researchers speed up production. Additionally, if there is a material failure, such as a tear, the sensors could point the researchers where to look in the process.

    The research team also plans to develop a virtual modeling system to refine the material-forming process through computer simulation instead of by trial and error. In this way, the team will better understand each step in the material-forming process, enhancing the team’s ability to make TuFF materials consistently and reliably — a must for aerospace applications.

    “I am hoping this work will allow us finally to make composites cost competitive with the metal industry,” said Advani.

    In addition to Thostenson and Advani, the team includes, from CCM, Jack Gillespie, Dirk Heider, Shridhar Yarlagadda, Thomas Cender, John Tierney and Pavel Simacek, along with four to five graduate students.

    Black Friday 2022 outlook: Cloudy with a chance of solid sales

    [ad_1]

    Analysts are split on projections for this year’s Black Friday. Markdowns could bring a solid haul for consumers and a stronger-than-expected economy may lead to a successful day for retailers. But the consensus seems to be that the biggest shopping day of the season could go either way. For example, there are concerns that price slashes will be on the stockpile of leftovers that didn’t sell earlier this year. And what about that whole supply chain bottleneck thing?

    The University of Delaware’s Alfred Lerner College of Business and Economics boasts several experts who can help make sense of it all:

    Andong Cheng: Can provide tips on what to prepare for during this unique holiday shopping season. Her research focuses on defining and identifying the picky consumer segment, and explores how pickiness impacts other judgments and decisions. She advises consumers to consider the phenomenon of double mental discounting, where shoppers experience a “mental accounting phenomenon” when offered promotional credit.

    Jackie Silverman: Research examines several facets of judgment and decision making and consumer psychology. According to Silverman, there are many potential benefits of online shopping for consumers, including some unconventional approaches to gift giving this season.

    Matthew McGranaghan: Studies the economics of consumer attention and the indirect effects of marketing interventions. He explains that there is a difference in how businesses are innovating and utilizing online retail methods to connect with consumers this holiday season.

    Bintong Chen: Can discuss the systematic nature of supply chain issues. He recommends shoppers use major retailers like Amazon and Walmart, whose companies use their own shipping fleets to minimize disruptions.

    Caroline Swift: Examines supply chain transparency and the interactions between regulation and business performance.
