Supporting the education of youth in foster care during the pandemic: foster parent and agency perspectives

Mary Rauktis, Fengyan Tang, Aimee Sgourakis, James Huguley & Rachel Robertson
Foster youth are at risk of poorer educational outcomes than their peers; foster youth take longer to graduate from secondary education, are less likely to obtain a high school diploma and less than 10% obtain a college diploma. Moreover, schools are a primary site for mental health services and counseling for this group of youth. The COVID-19 pandemic and educational closures has the potential to negatively impact educational and social gains for these youth, yet...

Transcending Disciplines to Advance Regional Water Equity

Emily Elliott, Marcela Gonzalez Rivas, Jackie Smith, Noble Maseru, Daniel Bain, Eitan Shelef, Eric Perry, Caitlin Schroering & Megan Guy
Pittsburgh has positioned itself as a city with a strong commitment to sustainable development, pledging to implement the United Nations Sustainable Development Goals including equitable access to clean water and sanitation. However, the City of Pittsburgh has also been identified as being the worst locale in the country for Black women, and inequities in race, class, and gender persist. Further, the region is challenged by a rapidly changing climate, aged and failing infrastructure, impaired water...

Reducing language obstacles that Deaf students face when developing scientific competencies

Richard Boyce, Malihe Alikhani , Sheila Pratt, David Boone & Kenneth De Haan
People who identify as Deaf or Hard of Hearing (Deaf/HoH) are highly underrepresented in research. Among the reasons for this disparity is the fact that Deaf/HoH students face significant obstacles to advancing in STEM including issues in accommodations, self-advocacy, and establishment of a support system. Our Momentum Fund Teaming project will develop and test a novel technology that supports Deaf/HoH students while learning biomedical topics using material available on the internet including educational videos, scientific...

Developing Communities of Research and Practice to Support Teacher Use of Proactive Behavior Management

Rachel Robertson, Kevin Binning & Thomas Farmer
Project CoRP (Communities of Research and Practice) seeks to narrow the research-practice divide in the use of proactive behavior management (PBM) strategies in schools by collaborating with teachers, caregivers, and students to create and test professional development modules aimed at increasing teacher use of PBM. Modules will incorporate (a) activities and messaging from social psychology shown to facilitate belief and behavior change, and (b) expertise of teachers and families of children who show challenging behavior...

Seed Imbibition Monitoring Using Millimeter-Scale Wireless Sensing Systems

Inhee Lee
Imbibition can be thought of as the resultant of soil moisture, soil structure, and pericarp permeability. Accurate imbibition monitoring enables to characterize one of three by holding the other two constant. It helps scientists and farmers find better soil or genotypes by assessing biologically-available soil moisture. However, we now know that a previous imaging-based approach is not effective since it cannot take images through the soil. Accordingly, there is an urgent need to develop a...

UPITT IVIS High-Temperature FTIR Data (Microfurnace)

James Thompson, Daniel Williams, Rachel Jennifer Lee & Michael Sean Ramsey
This data is related to the following manuscript: Quantitative thermal emission spectroscopy at high-temperatures: A laboratory approach for measurement and calibration. A new microfurnace was developed to heat mineral and rock samples to temperatures between 473 and 1573 K. It was designed to integrate with an existing Nicolet Nexus 670 FTIR spectrometer (with a a liquid nitrogen-cooled mercury cadmium telluride (MCT-B) detector)allowing quantitative emission spectra of samples over the 4000 – 500 cm-1 (2.5 –...

Discovering drugs to treat osteoarthritis with a knee joint-on-a-chip model

Hang Lin, Sung Kwon Cho & Shilpa Sant
Osteoarthritis (OA) is the most prevalent degenerative joint disease, which is mainly characterized by pain and physical disability. Currently, no FDA-approved disease-modifying OA drugs (DMOADs) are currently available to stop, slow, or reverse the progression of OA. Numerous DMOADs have been investigated, but the results were disappointing and subsequently terminated. The reasons for the failures included unexpected toxicity and poor treatment outcomes that were not identified during preclinical studies, suggesting deficiencies of currently available models...

Highly Scalable and Efficient Deep Learning Accelerator Enabled by 3D Photonic Integration

Nathan Youngblood
The positive societal impacts of artificial intelligence (AI) through the field of deep learning have been thrilling to witness, but these advances come with an increasingly unsustainable appetite for computing resources. Thus, the generality and accuracy of deep learning—which fundamentally scale with the amount of training data and available computation—is also its Achilles’ heel. Novel approaches to computation are therefore needed to address the slowing growth in compute performance and efficiency of electronic hardware in...

Black on the Edge: Amplifying Pittsburgh HBCU Narratives

Khirsten Scott
Historically Black Colleges and Universities (HBCUs) were created as a corrective to the legacy of slavery’s having outlawed the formal education of Black people. Although the U.S.’s 107 HBCUs now account for merely 3 percent of US colleges and universities, public discourse surrounding them often hinges on questions about their efficacy and relevance in addressing structural racism. My developing book to satisfy tenure requirements, Black on the Edge: Rhetorics of HBCU Survival, poses the question:...

Data Mining Approach to Understand Tensor Properties in Turbulent Cascade

Lei Fang
Traditionally, turbulence study starts from unproven but plausible hypotheses (e.g. Kolmogorov's similarity hypotheses) and then proceeding in a systematic fashion to reach theory (e.g. K41). The results are then tested against the experimental data for correctness and completeness. While this hypothetical-deductive-like-method received many successes in history, it has its detrimental limitation: starting from a plausible hypothesis precludes any other possibilities. Since the turbulent data is the final test for turbulent theories, why not start by...

Making Skeletons of Shapes Dance

Paul Gartside
Topology is the study of shape. During this project a bridge will be built between the continuous, infinite world of shapes and the combinatorial, finite domain of graphs (networks). To each shape will be associated a sequence of `1-skeletons' which are graphs. By employing recent developments in graph theory these skeletons will be put to work (`made to dance') both as a theoretical tool in topology, but also as a practical tool to understand shapes...

Quarry 2 Floor Tile

Ruikang Ding, Abhijeet Gujrati, Matthew M. Pendolino, Kurt E. Beschorner & Tevis D. B. Jacobs
These are surface profiles of quarry 2 rough flooring. The quarry 1 (0T01881P, Daltile, Dallas, TX, USA) and quarry 2 (01 010 SM 1, Summitville, OH, USA) were commercial tiles, where the full composition was a trade secret, but they were known to include 15-25 wt% quartz, and quarry 2 also included abrasive grits on the surface, presumably to improve slip resistance. There are 30 profiles generated from image analysis and measured by SEM. 10...

Data from: Discovery of metabolic biomarkers for Duchenne Muscular Dystrophy within a natural history study

Simina M. Boca, Maki Nishida, Michael Harris, Shruti Rao, Amrita K. Cheema, Kirandeep Gill, Haeri Seol, Lauren P. Morgenroth, Erik Henricson, Craig McDonald, Jean K. Mah, Paula R. Clemens, Eric P. Hoffman, Yetrib Hathout & Subha Madhavan
Serum metabolite profiling in Duchenne muscular dystrophy (DMD) may enable discovery of valuable molecular markers for disease progression and treatment response. Serum samples from 51 DMD patients from a natural history study and 22 age-matched healthy volunteers were profiled using liquid chromatography coupled to mass spectrometry (LC-MS) for discovery of novel circulating serum metabolites associated with DMD. Fourteen metabolites were found significantly altered (1% false discovery rate) in their levels between DMD patients and healthy...

Data from: Fat, fibre and cancer risk in African Americans and rural Africans

Stephen J. D. O’Keefe, Jia V. Li, Leo Lahti, Junhai Ou, Franck Carbonero, Mohammed Khaled, Joram M. Posma, James Kinross, Elaine Wahl, Elizabeth Ruder, Kishore Vipperla, Vasudevan Naidoo, Lungile Mtshali, Sebastian Tims, Philippe G. B. Puylaert, James DeLany, Alyssa Krasinskas, Ann C. Benefiel, Hatem O. Kaseb, Keith Newton, Jeremy K. Nicholson, Willem M. De Vos, H. Rex Gaskins & Erwin G. Zoetendal
Rates of colon cancer are much higher in African Americans (65:100,000) than in rural South Africans (<5:100,000). The higher rates are associated with higher animal protein and fat, and lower fibre consumption, higher colonic secondary bile acids, lower colonic short-chain fatty acid quantities and higher mucosal proliferative biomarkers of cancer risk in otherwise healthy middle-aged volunteers. Here we investigate further the role of fat and fibre in this association. We performed 2-week food exchanges in...
