2020-Current year OA Pubs

BACKGROUND: Race is commonly used as a proxy for multiple features including socioeconomic status. It is critical to dissociate these factors, to identify mechanisms that affect infant outcomes, such as birth weight, gestational age, and brain development, and to direct appropriate interventions and shape public policy.

METHODS: Demographic, socioeconomic, and clinical variables were used to model infant outcomes. There were 351 participants included in the analysis for birth weight and gestational age. For the analysis using brain volumes, 280 participants were included after removing participants with missing magnetic resonance imaging scans and those matching our exclusion criteria. We modeled these …

Intrusive Traumatic Re-Experiencing Domain: Functional Connectivity Feature Classification By The Enigma Ptsd Consortium, Benjamin Suarez-Jimenez, Evan M Gordon, Et Al.

2020-Current year OA Pubs

BACKGROUND: Intrusive traumatic re-experiencing domain (ITRED) was recently introduced as a novel perspective on posttraumatic psychopathology, proposing to focus research of posttraumatic stress disorder (PTSD) on the unique symptoms of intrusive and involuntary re-experiencing of the trauma, namely, intrusive memories, nightmares, and flashbacks. The aim of the present study was to explore ITRED from a neural network connectivity perspective.

METHODS: Data were collected from 9 sites taking part in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) PTSD Consortium (

RESULTS: rsFC signatures differentiated TE-only participants from PTSD and ITRED-only participants at about 60% accuracy. Conversely, rsFC signatures did …

Multiple Genes Core To Erad, Macroautophagy And Lysosomal Degradation Pathways Participate In The Proteostasis Response In Α1-Antitrypsin Deficiency, Jie Li, Tunda Hidvegi, Sanja Sviben, James A J Fitzpatrick, Hemalatha Sundaramoorthi, Stephen C Pak, Gary A Silverman, David H Perlmutter, Et Al.

2020-Current year OA Pubs

BACKGROUND & AIMS: In the classic form of α1-antitrypsin deficiency (ATD), the misfolded α1-antitrypsin Z (ATZ) variant accumulates in the endoplasmic reticulum (ER) of liver cells. A gain-of-function proteotoxic mechanism is responsible for chronic liver disease in a subgroup of homozygotes. Proteostatic response pathways, including conventional endoplasmic reticulum-associated degradation and autophagy, have been proposed as the mechanisms that allow cellular adaptation and presumably protection from the liver disease phenotype. Recent studies have concluded that a distinct lysosomal pathway called endoplasmic reticulum-to-lysosome completely supplants the role of the conventional macroautophagy pathway in degradation of ATZ. Here, we used several state-of-the-art approaches …

White matter hyperintensities (WMH) are nearly ubiquitous in the aging brain, and their topography and overall burden are associated with cognitive decline. Given their numerosity, accurate methods to automatically segment WMH are needed. Recent developments, including the availability of challenge data sets and improved deep learning algorithms, have led to a new promising deep-learning based automated segmentation model called TrUE-Net, which has yet to undergo rigorous independent validation. Here, we compare TrUE-Net to six established automated WMH segmentation tools, including a semi-manual method. We evaluated the techniques at both global and regional level to compare their ability to detect the …

Thyroid hormone receptor-interacting protein 13 (TRIP13) is involved in cancer progression, but its role in pancreatic ductal adenocarcinoma (PDAC) is unknown. Thus, we assessed the expression, functional role, and mechanism of action of TRIP13 in PDAC. We further examined the efficacy of TRIP13 inhibitor, DCZ0415, alone or in combination with gemcitabine on malignant phenotypes, tumor progression, and immune response. We found that TRIP13 was overexpressed in human PDACs relative to corresponding normal pancreatic tissues. TRIP13 knockdown or treatment of PDAC cells with DCZ0415 reduced proliferation and colony formation, and induced G2/M cell cycle arrest and apoptosis. Additionally, TRIP13 knockdown or …

Predictability And Adaptation In Law And Other Markets (Chapter In A Coming Book: Research Handbook On Law And Time), Saul Levmore

Coase-Sandor Institute for Law & Economics Research Paper Series

People and enterprises that are subject to the law find it useful to know what the law is at present, but then also to anticipate future rules. If laws are stable this is easily done. Stability is more common where the judicial branch is concerned, because precedents are often valued, and for good reason. They are more often followed by judges than by those involved in other methods of lawmaking. But in all of lawmaking, and even in the private sphere, there is value to consistency and certainty. And yet, surprises can be attractive if they are not confronted on …

Ownership Topology Of Vertically-Scaled Agile, William Dabney

Theses

Much as Scrum, Kanban, and XP are used to structure team-level agility, those wishing to take agility beyond the team level often turn to proven solutions. The most popular, which aim to scale development by adding teams under a shared collective ownership rather than separating them into discrete units, are the Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Nexus. These frameworks advocate for aligning ownership subdivisions along features rather than code, which allows teams working on the same product to do so autonomously. While the benefits of this have been researched, the topology of ownership in these frameworks …

OES Faculty Publications

The field of oceanography is transitioning from data-poor to data-rich, thanks in part to increased deployment of in-situ platforms and sensors, such as those that instrument the US-funded Ocean Observatories Initiative (OOI). However, generating science-ready data products from these sensors, particularly those making biogeochemical measurements, often requires extensive end-user calibration and validation procedures, which can present a significant barrier. Openly available community-developed and -vetted Best Practices contribute to overcoming such barriers, but collaboratively developing user-friendly Best Practices can be challenging. Here we describe the process undertaken by the NSF-funded OOI Biogeochemical Sensor Data Working Group to develop Best Practices for …

Barriers And Variable Spacing Enhance Convective Cooling And Increase Power Output In Solar Pv Plants, Brooke Stanislawski, Todd Harman, Raul Bayoan Cal, Marc Calaf

Mechanical and Materials Engineering Faculty Publications and Presentations

When the temperature of solar photovoltaic (PV) modules rises, efficiency drops and module degradation accelerates. Thus, it is beneficial to reduce module operating temperatures. Previous studies of solar power plants have illustrated that incoming flow characteristics, turbulent mixing, and array geometry can strongly impact convective cooling, as measured by the convective heat transfer coefficient h. In the fields of heat transfer and plant canopy flow, previous work has shown that system-scale arrangement modifications—e.g., variable spacing, barriers, or windbreaks—can passively alter the flow, enhance turbulent mixing, and influence convection. However, researchers have not yet explored how variable spacing or barriers …

Revisiting Rockafellar’S Theorem On Relative Interiors Of Convex Graphs With Applications To Convex Generalized Differentiation, Boris S. Mordukhovich, Nguyen Mau Nam, Dang Van Cuong, G. Sandine

Mathematics and Statistics Faculty Publications and Presentations

In this paper we revisit a theorem by Rockafellar on representing the relative interior of the graph of a convex set-valued mapping in terms of the relative interior of its domain and function values. Then we apply this theorem to provide a simple way to prove many calculus rules of generalized differentiation for set-valued mappings and nonsmooth functions in finite dimensions. Using this important theorem by Rockafellar allows us to improve some results on generalized differentiation of set-valued mappings in [13] by replacing the relative interior qualifications on graphs with qualifications on domains and/or ranges.

Obesity is associated with a multitude of comorbidities, such as cardiovascular disease, diabetes mellitus, and osteoarthritis (Lim, Boster, 2023). Additionally, obesity may cause psychological disorders due to social prejudice and discrimination toward obese people (Wadden et al. 2002). Economically, obesity is also a tremendous financial burden (Tremmel et al. 2017). It is estimated that the overall cost of obesity-related illness in the US is nearly $500 billion (Cawley et al., …

Extraordinary Punishment: Conditions Of Confinement And Compassionate Release, Meredith B. Esser

Scholarly Works

People experience severe forms of harm while incarcerated, including medical neglect, prolonged solitary confinement, sexual and physical violence, and a host of other ills. But civil rights litigation under the Eighth Amendment the most common vehicle through which people seek to redress these harms presents significant practical and doctrinal barriers to incarcerated plaintiffs. Most notably, the Eighth Amendment's "deliberate indifference" standard asks not whether a person has been harmed, but instead requires plaintiffs to demonstrate a criminally reckless mental state on the part of prison officials. Further, Eighth Amendment remedies are limited to damages or injunctions, which may not adequately …
