Every year the United States invests $3.2 billion in the Small Business Innovation Research (SBIR) program to promote innovation among the nation’s small businesses. Half of this investment is from the DoD. This research considers the challenges faced by small businesses innovating with the DoD, particularly those awarded SBIR contracts with the United States Air Force. The authors surveyed 286 unique small businesses that were previously awarded an Air Force SBIR contract. By asking the survey respondents open-ended questions and categorizing their responses, they pinpoint unaddressed challenges from the small business perspective. By categorizing survey responses through Qualitative Content Analysis, …

Production Box Cost Estimating Relationships For Dod Avionics, Carla J. Cisneros, Edward D. White, Brandon M. Lucas, Jonathan D. Ritschel, Robert D. Fass, Shawn M. Valentine

Faculty Publications

The authors use historical information obtained from the Cost Assessment Data Enterprise to estimate recurring production unit cost for DoD avionics via cost estimating relationships (CERs). The specific modeled responses include mean unit cost, median unit cost, and the 100th production unit cost (T100) utilizing learning curve theory. For T100, the authors adopt both a multiplicative and an additive error for CER comparison. Recommended CERs consist of the mean unit cost and the T100 utilizing a multiplicative error. Moreover, results reveal that weight has a significant effect on cost as well as a potential underaccounting of real price change or …

Intellectual Property, Genetic Resources, And Associated Traditional Knowledge, N.S. Gopalakrishnan, Srividhya Ragavan, Narendran Thiruthy

Faculty Scholarship

The recently concluded WIPO Treaty on Intellectual Property, Genetic Resources and Associated Traditional Knowledge mandates disclosure requirements in patent applications, thereby creating an obligation to attribute the use of genetic resources and traditional knowledge. The WIPO member countries thus have an opportunity to modify their national patent laws, so that they can effectively control genetic resources and traditional knowledge. This article examines the choices that the biodiversity-rich countries have when designing their national legal systems to implement the treaty.

Shifting Toward Boilerplate Regulation, Wayne R. Barnes

Faculty Scholarship

Consumer assent to standard form contracts has been creating cognitive dissonance among contracts scholars for a century. Businesses impose standard forms on consumers, who never read the terms. But consumers would not understand them if they did. And they don’t have the bargaining power to change them anyway—the terms are famously “take it or leave it.” Contracting is ideally theorized as an act of voluntary, knowing consent to all the terms agreed to. The dissonance is that consumers, although ostensibly signaling their assent to the boilerplate by signing (or clicking, or tapping their phone screen), do not in fact know …

Role Of The Card8 Inflammasome In Hiv Pathogenesis, Qiankun Wang, Liang Shan

2020-Current year OA Pubs

Human immunodeficiency virus (HIV) continues to be a significant global health challenge despite decades of research and advances in treatment. Substantial gaps in our understanding of the mechanisms of HIV pathogenesis and the host immune responses still exist. The interaction between HIV and these immune responses is pivotal in the disease progression to acquired immunodeficiency syndrome (AIDS). Recently, the caspase recruitment domain-containing protein 8 (CARD8) inflammasome has emerged as a crucial factor in orchestrating innate immune responses to HIV infection and exerting a substantial impact on viral pathogenesis. CARD8 restricts viral replication by detecting the activity of HIV protease. Conversely, …

Deletion Of Tissue Factor Pathway Inhibitor Isoform Beta Or Gamma, But Not Alpha, Improves Clotting In Hemophilic Mice, Irem Eldem, Lilian Antunes-Heck, Renumathi Subramanian, Nina M Lasky, Katrina Ashworth, Jorge Di Paola, Thomas J Girard

2020-Current year OA Pubs

BACKGROUND: Tissue factor pathway inhibitor (TFPI) regulates tissue factor-triggered coagulation. Humans and mice express transcripts encoding for multidistributed (endothelial, platelet, and plasma) 3-Kunitz domain TFPIα and endothelial membrane-anchored 2-Kunitz TFPIβ. Mice express a third transcript, γ, that encodes plasma lipoprotein-associated 2-Kunitz TFPI. In humans, proteolysis of α and/or β produces plasma lipoprotein-associated 2-Kunitz TFPI at lower levels. In clinical trials, monoclonal antibodies that target all TFPI isoforms extend coagulation and correct bleeding in hemophilic patients but with some thrombosis risks.

OBJECTIVES: To determine the impact of TFPI isoform-specific deletions on promoting clotting in hemophilic mice.

METHODS: Engineered TFPI isoform-specific, hemophilic …

Peripartum Prediction Of Fetal Weight In Gravidas With Obesity, Katherine H Bligard, Jeannie C Kelly, Antonina I Frolova, Anthony O Odibo, Nandini Raghuraman

2020-Current year OA Pubs

OBJECTIVES: Estimated fetal weight (EFW) is an important metric at delivery as neonates with abnormal birthweight and their mothers are at higher risk of birth complications. Data regarding optimal EFW assessment in gravidas with obesity is inconsistent, and with the increasing incidence of obesity, clarification of this question is crucial. We aimed to compare accuracy of ultrasound (US)-derived EFW and clinical assessments of EFW in predicting neonatal birthweight among gravidas with obesity.

METHODS: This prospective cohort study enrolled gravidas with obesity and a singleton pregnancy admitted for delivery at term. EFW was determined using either US biometry or clinical assessment …

Corticosteroid Burst Therapy In Patients With Acute Heart Failure: Design Of The Cortahf Pilot Study, Gad Cotter, Douglas L Mann, Et Al.

2020-Current year OA Pubs

AIMS: Inflammation has emerged as a potential key pathophysiological mechanism in heart failure (HF) in general and acute HF (AHF) specifically, with inflammatory biomarkers shown to be highly predictive of adverse outcomes in these patients. The CORTAHF study builds on both these data and the fact that steroid burst therapy has been shown to be effective in the treatment of respiratory diseases and COVID-19. Our hypothesis is that in patients with AHF and elevated C-reactive protein (CRP) levels without symptoms or signs of infection, a 7-day course of steroid therapy will lead to reduced inflammation and short-term improvement in quality …

2020-Current year OA Pubs

Genetic backgrounds influence cellular phenotypes, drug responses, and health outcomes, yet most human iPSC lines are derived from individuals of European descent, with lines from indigenous Africans particularly scarce. Addressing this gap, we generated iPSCs from dermal fibroblasts of a healthy 60-year-old indigenous Nigerian male of the Babur ethnic group using Sendai virus. The iPSC line displayed a normal karyotype, was characterized for pluripotency markers and differentiated into neural progenitor cells and astrocytes. To enhance African representation in research, this iPSC line will be available to the scientific community, with ongoing efforts focused on creating an open-access African iPSC biobank. …

Western Diet Reduces Small Intestinal Intraepithelial Lymphocytes Via Fxr-Interferon Pathway, Chen-Ting Hung, Changqing Ma, Santosh K Panda, Tihana Trsan, Miki Hodel, Jennifer Frein, Amanda Foster, Shengxiang Sun, Hung-Ting Wu, Justin Kern, Richa Mishra, Umang Jain, Marco Colonna, Ta-Chiang Liu, Et Al.

2020-Current year OA Pubs

The prevalence of obesity in the United States has continued to increase over the past several decades. Understanding how diet-induced obesity modulates mucosal immunity is of clinical relevance. We previously showed that consumption of a high fat, high sugar "Western" diet (WD) reduces the density and function of small intestinal Paneth cells, a small intestinal epithelial cell type with innate immune function. We hypothesized that obesity could also result in repressed gut adaptive immunity. Using small intestinal intraepithelial lymphocytes (IEL) as a readout, we found that in non-inflammatory bowel disease (IBD) subjects, high body mass index correlated with reduced IEL …

Immune Checkpoint Markers And Tumour Mutation Burden In Wilms Tumour: A Study Of 59 Cases, Aidas J Mattis, Jie-Fu Chen, Ivan A Gonzalez, Rehan Rais, Louis P Dehner, John Pfeifer, Mai He

2020-Current year OA Pubs

Wilms tumour (WT) is the most common renal tumour in children, and studies of immune checkpoint inhibitors (ICIs) treatment and markers are limited in number. In this study we investigated the ICIs' related immune landscape by examining the expression of PD-L1, PD-1, CD8 and DNA mismatch repair (MMR) proteins by immunohistochemistry (IHC), tumour mutation burden (TMB), and correlations with histology and clinical outcome. Positive PD-L1 (SP263) expression was defined as modified combined positive score (CPS) ≥1. A total of 59 WTs (from 2000 to 2017), including eight (14.0%) with anaplasia, from 46 patients were analysed (45 primary and 14 metastatic). …

Soprano: Macitentan In Patients With Pulmonary Hypertension Following Left Ventricular Assist Device Implantation, Robert P Frantz, Gregory Ewald, Joel D Schilling, Et Al.

2020-Current year OA Pubs

Macitentan is a dual endothelin receptor antagonist (ERA) approved for treating pulmonary arterial hypertension (PAH). SOPRANO evaluated the efficacy and safety of macitentan versus placebo in pulmonary hypertension (PH) patients after left ventricular assist device (LVAD) implantation. SOPRANO was a phase 2, multicenter, double-blind, randomized, placebo-controlled, parallel-group study. Patients with an LVAD implanted within the prior 90 days who had persistent PH (i.e., mean pulmonary arterial pressure ≥25 mmHg, pulmonary artery wedge pressure [PAWP] ≤18 mmHg, and pulmonary vascular resistance [PVR] >3 Wood units [WU]) were randomized (1:1) to macitentan 10 mg or placebo once daily for 12 weeks.

2020-Current year OA Pubs

Adult T cell leukaemia (ATL), caused by infection with human T- lymphotropic virus type 1 (HTLV-1), is often complicated by hypercalcemia and osteolytic lesions. Therefore, we studied the communication between patient-derived ATL cells (ATL-PDX) and HTLV-1 immortalized CD4+ T cell lines (HTLV/T) with osteoclasts and their effects on bone mass in mice. Intratibial inoculation of some HTLV/T leads to a profound local decrease in bone mass similar to marrow-replacing ATL-PDX, despite the fact that few HTLV/T cells persisted in the bone. To study the direct effect of HTLV/T and ATL-PDX on osteoclasts, supernatants were added to murine and human osteoclast …

Ontogenetic changes in area use, habitat use, and trophic interactions play an important role in the ecology, demography, and ultimately population dynamics of many species. Assumed to be driven by shifting life-history requirements, trophic niche shifts in white sharks (Carcharodon carcharias) are well documented, but the timing of the spatial niche shift that is hypothesized to occur with the trophic niche shift remains poorly understood. To document how fine-scale area use varies as sharks age and the timing of the ontogenetic spatial shift of this top predator, we tracked individual white sharks tagged as young-of-the-year or young juveniles …

Caregiver Wellness After Traumatic Brain Injury (Cg-Well): Protocol For A Randomized Clinical Trial, Natalie Kreitzer, Stephanie Fink, Opeolu Adeoye, Brad Kurowski G, Shari Wade, Heidi Sucharew, Tamilyn Bakas

2020-Current year OA Pubs

INTRODUCTION: After injury, survivors of moderate to severe traumatic brain injury (msTBI) depend on informal family caregivers. Upwards of 77 % of family caregivers experience poor outcomes, such as adverse life changes, poor health-related quality of life, and increased depressive symptoms. Caregivers frequently report minimal support or training to prepare them for their new role. The majority of previously developed caregiver and caregiver/survivor dyad interventions after msTBI focus on providing information to either survivors only, or to long-term caregivers, rather than to the new caregiver. This manuscript describes the protocol of an ongoing randomized control trial, Caregiver Wellness after TBI …

Type I Ifn Signaling In The Absence Of Irgm1 Promotes M. Tuberculosis Replication In Immune Cells By Suppressing T Cell Responses, Sumanta K Naik, Michael E Mcnehlan, Yassin Mreyoud, Rachel L Kinsella, Asya Smirnov, Chanchal Sur Chowdhury, Samuel R Mckee, Neha Dubey, Reilly Woodson, Darren Kreamalmeyer, Christina L Stallings

Polymorphisms in the IRGM gene are associated with susceptibility to tuberculosis in humans. A murine ortholog of Irgm, Irgm1, is also essential for controlling Mycobacterium tuberculosis (Mtb) infection in mice. Multiple processes have been associated with IRGM1 activity that could impact the host response to Mtb infection, including roles in autophagy-mediated pathogen clearance and expansion of activated T cells. However, what IRGM1-mediated pathway is necessary to control Mtb infection in vivo and the mechanistic basis for this control remains unknown. We dissected the contribution of IRGM1 to immune control of Mtb pathogenesis in vivo and found that Irgm1 deletion leads …

The Long Life Family Study (LLFS) enrolled 4953 participants in 539 pedigrees displaying exceptional longevity. To identify genetic mechanisms that affect cardiovascular risks in the LLFS population, we developed a multi-omics integration pipeline and applied it to 11 traits associated with cardiovascular risks. Using our pipeline, we aggregated gene-level statistics from rare-variant analysis, GWAS, and gene expression-trait association by Correlated Meta-Analysis (CMA). Across all traits, CMA identified 64 significant genes after Bonferroni correction (p ≤ 2.8 × 10

Oxyfluorfen Use In Combination With Clomazone Or Quinclorac, Jason K. Norsworthy, Casey H. Arnold, Thomas R. Butts, Chad W. Shelton

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Oxyfluorfen is a herbicide that inhibits protoporphyrinogen IX oxidase and has shown significant potential in its ability to control barnyardgrass. Oxyfluorfen is categorized as a Group 14 herbicide by the Herbicide Resistance Action Committee (HRAC)/Weed Science Society of America (WSSA). Despite its current lack of labeling for use on rice in the mid-southern United States due to its potential to cause crop injury, the introduction of a trait in rice that confers resistance to oxyfluorfen could provide producers with an effective alternative site of action for weed control. Field experiments were conducted during the 2021 and 2022 growing seasons near …

Conducting Structure-From-Motion (Sfm) Modeling Of Freshwater Environments Using Unpiloted Aerial Systems (Uas): Challenges And Lessons Learned, Benjamin T. Fraser, Christine L. Bunyon, Russell G. Congalton

Faculty Publications

The pairing of Unpiloted Aerial Systems (UAS) and Structure from Motion (SfM) has provided new capabilities for modeling freshwater environments. Applications of UAS-SfM range from water quality monitoring to the mapping of aquatic vegetation. The models produced provide users with the ability to analyze features at ultra-high-resolutions and across scales not easily achieved through in situ sampling. Despite the demonstrated benefits of UAS-SfM in freshwater and other natural resource disciplines, there remain fundamental technical challenges in the modeling of environments with homogenous surfaces (e.g., water). In this research, the effectiveness of several image collection and processing approaches for the modelling …

School of Medicine Publications

Autism spectrum disorder (ASD) is a neurodevelopmental disorder (NDD) that affects approximately 4% of males and 1% of females in the United States. While causes of ASD are multi-factorial, single rare genetic variants contribute to around 20% of cases. Here we report a case series of seven unrelated probands (6 males, 1 female) with ASD or another variable NDD phenotype attributed to de novo heterozygous loss of function or missense variants in the gene LARP1. LARP1 encodes an RNA binding protein that post-transcriptionally regulates the stability and translation of thousands of mRNAs, including those regulating cellular metabolism and metabolic plasticity. …

Topological Cluster Statistic (Tcs): Toward Structural Connectivity–Guided Fmri Cluster Enhancement, Sina Mansour L., Caio Seguin, Anderson M. Winkler, Stephanie Noble, Andrew Zalesky

School of Medicine Publications

Abstract

Functional magnetic resonance imaging (fMRI) studies most commonly use cluster-based inference to detect local changes in brain activity. Insufficient statistical power and disproportionate false-positive rates reportedly hinder optimal inference. We propose a structural connectivity–guided clustering framework, called topological cluster statistic (TCS), that enhances sensitivity by leveraging white matter anatomical connectivity information. TCS harnesses multimodal information from diffusion tractography and functional imaging to improve task fMRI activation inference. Compared to conventional approaches, TCS consistently improves power over a wide range of effects. This improvement results in a 10%–50% increase in local sensitivity with the greatest gains for medium-sized effects. TCS …

High-Latitude Observations Of Dissipation-Range Turbulence By The Ulysses Spacecraft During The Solar Minimum Of 1993–96: The Spectral Break And Anisotropy, Abigale S. Watson, Charles W. Smith, Anastasia V. Marchuk, Matthew R. Argall, Colin J. Joyce, Philip A. Isenberg, Bernard J. Vasquez, Nathan A. Schwadron, Neil Murphy

Faculty Publications

We examine Ulysses magnetic field observations from 1993 to 1996 as the spacecraft made its first fast-latitude scan from the southern to the northern hemisphere. Most of the observations we use are representative of high-latitude solar minimum conditions. We examine magnetic field power spectra characteristics of interplanetary turbulence at high frequencies, where the spectrum breaks from an inertial range into the ion dissipation range. The onset and spectral index of the dissipation spectrum are consistent with low-latitude observations at 1 au. Both ranges have a ratio of power in perpendicular magnetic field components to parallel components near 3. The power …
