Madfam: Microarchitectural Data Framework And Methodology, Tor J. Langehaug, Scott R. Graham, Christine M. Schubert Kabban, Brett J. Borghetti

Faculty Publications

In the aftermath of Spectre and Meltdown researchers have proposed a variety of attack detection solutions by applying machine learning to data collected from hardware performance monitoring units. Although many microarchitectural attack detection systems provide high-accuracy detection results, the behavior of the underlying data collection mechanisms is not well described or understood. This research introduces the MicroArchitectural Data Framework And Methodology (MADFAM) to prescribe a systematic approach to collecting and preserving the information available in sequences of microarchitectural data. The proposed framework focuses on hardware performance counters (HPCs) as the primary data source. HPC configuration is complex, which makes it …

Spin-Nernst Effect In Time-Reversal-Invariant Topological Superconductors, Taiki Matsushita, Jiei Ando, Yusuke Masaki, Takeshi Mizushima, Satoshi Fujimoto, Ilya Vekhter

Faculty Publications

We investigate the spin-Nernst effect in time-reversal-invariant topological superconductors, and show that it provides smoking-gun evidence for helical Cooper pairs. The spin-Nernst effect stems from asymmetric, in spin space, scattering of quasiparticles at nonmagnetic impurities, and generates a transverse spin current by the temperature gradient. Both the sign and the magnitude of the effect sensitively depend on the scattering phase shift at impurity sites. Therefore the spin-Nernst effect is uniquely suitable for identifying time-reversal-invariant topological superconducting orders.

Task-Based Functional Connectivity And Blood-Oxygen-Level-Dependent Activation During Within-Scanner Performance Of Lumbopelvic Motor Tasks: A Functional Magnetic Resonance Imaging Study, Mark K. Jordon, Jill Campbell Stewart Pt,Phd, Sheri P. Silfies, Paul F. Beattie

Faculty Publications

There are a limited number of neuroimaging investigations into motor control of the lumbopelvic musculature. Most investigation examining motor control of the lumbopelvic musculature utilize transcranial magnetic stimulation (TMS) and focus primarily on the motor cortex. This has resulted in a dearth of knowledge as it relates to how other regions of the brain activate during lumbopelvic movement. Additionally, task-based functional connectivity during lumbopelvic movements has not been well elucidated. Therefore, we used functional magnetic resonance imaging (fMRI) to examine brain activation and ROI-to-ROI task-based functional connectivity in 19 healthy individuals (12 female, age 29.8 ± 4.5 years) during the …

The Transcription Factor Vpxlnr Is Required For The Growth, Development, And Virulence Of The Fungal Pathogen Valsa Pyri, Feng He, Alex-Machio Kange, Jie Yang, Jiaxin Xiao, Rongbo Wang, Lu Yang, Yifan Jia, Zhengqing Fu, Yancun Zhao, Fengquan Liu

Faculty Publications

Pears (Pyrus sp.) are widely cultivated in China, and their yield accounts for more than 60% of global pear production. The fungal pathogen Valsa pyri is a major causal agent of pear canker disease, which results in enormous losses of pear production in northern China. In this study, we characterized a Zn₂Cys₆ transcription factor that contains one GAL4 domain and a fungal-trans domain, which are present in VpxlnR. The vpxlnR gene expression was upregulated in the invasion stage of V. pyri. To investigate its functions, we constructed gene deletion mutants and complementary strains. We observed …

Prediction Of Pressure Increase During Waste Water Injection To Prevent Seismic Events, Lu Jin, Andrew K. Wojtanowicz, Jun Ge

Faculty Publications

A considerable increase of seismicity has occurred in the USA in the last decade (2009–2020) with an annual average of 345 M3+ earthquakes. Numerous field cases have shown that excessive well pressure due to a high injection rate may have triggered seismic events. This study defines conditions for inducing a seismic event by excessive injection in the well’s pressure that may cause geomechanical damage to the rock. Introduced here is an analytical model and method for predicting pressure increase during injection of produced water contaminated with oil. The model calculates time-dependent advancement of the captured oil saturation causing the well’s …

The Perfect Storm: Substance Abuse, Mental Illness, And Rural America, Bailey D. Barnes

Faculty Publications

Across the United States in the late twentieth and early twenty-first century, substance abuse and mental illness have clashed with the criminal justice system to produce inequitable and tragic results. The War on Drugs especially affects rural communities, where resources for rehabilitative services, mental health treatment, and transitional housing are scarce. In these areas, the significant strain on the criminal justice system caused by the frequent intersection of substance abuse and mental illness has wrought overcrowded correctional facilities, congested criminal court dockets, exhausted public defenders, and devastated families. This Article is a case study of one such rural community's experience …

Writing By Presidential Example: The First Inaugural Addresses Of Reagan And Obama, Douglas E. Abrams

Faculty Publications

This article is about two recent U.S. presidents who differed from one another in prominent respects. One entered the Oval Office as a staunch Republican; the other entered as a staunch Democrat. One was one of the oldest men ever to serve in the Oval Office; the other was one of the youngest. The pair assumed contrasting positions on the political spectrum.

Despite these differences, however, the pair – Ronald Reagan and Barack Obama – shared an important common denominator. As president, both achieved recognition as “great communicators,” thanks in large part to their speeches marked by dexterity with the …

Faculty Publications

The coronavirus disease 2019 (COVID-19) pandemic's first wave led to declining mental health and life satisfaction outcomes for college students, especially women. While women in undergraduate agricultural programs outperformed men academically prior to and during the pandemic, the achievement may have come at personal cost, especially for those women with fewer personal and environmental resiliency resources. Our research objective was to expand on personal, social, and environmental factors linked with lower mental health and life satisfaction scores for students in agriculture during the pandemic. We measured the influence of such factors across gender-based mental health and life satisfaction outcomes. Our …

A Comparison Of Hay And Fish Emulsion-Infused Water As Oviposition Attractants For The Cdc Gravid Trap, Timothy D. Mcnamara, Kristen Healy

Faculty Publications

Multiple oviposition attractants are used for Culex (Diptera: Culicidae) mosquito surveillance in the CDC Gravid Trap, including hay and fish emulsion-infused water. Despite the use of both in the United States, no research has compared their attractiveness. We conducted trapping throughout Louisiana to assess the attractiveness of hay and fish emulsion-infused water in various habitat types and climates. Our results indicate that fish emulsion-infused water attracts more mosquitoes overall, more Culex quinquefasciatus (Say, 1823), and a wider diversity of mosquitoes than hay-infused water. This trend was maintained, regardless of habitat type or climate.

Density Dependent Refueling Of Migratory Songbirds During Stopover Within An Urbanizing Coastal Landscape, Emily B. Cohen, Jill M. Lafleur, Frank R. Moore

Faculty Publications

Refueling performance is the primary currency of a successful migration as birds must maintain energy stores to achieve an optimal travel schedule. Migrating birds can anticipate heightened energy demand, not to mention increased uncertainty that energy demands will be satisfied, especially within an urbanizing landscape following long-distance flights. We tested the expectation that refueling performance of songbirds is reduced as densities increase at stopover sites in an urbanizing coastline of the Gulf of Mexico. We measured the density of migrating birds, their refueling performance, and arthropod abundance in two large tracts of contiguous forest paired with two small isolated patches …

Faculty Publications

In this work, an attempt has been made to explore numerically the thermo-fluidic transport process in a novel M-shaped enclosure filled with permeable material along with Al₂O₃-Cu hybrid nanoparticles suspended in water under the influence of a horizontal magnetizing field. To exercise the influence of geometric parameters, a classical trapezoidal cavity is modified with an inverted triangle at the top to construct an M-shaped cavity. The cavity is heated isothermally from the bottom and cooled from the top, whereas the inclined sidewalls are insulated. The role of geometric parameters on the thermal performance is scrutinized thoroughly …

Off-Peak Ndvi Correction To Reconstruct Landsat Time Series For Post-Fire Recovery In High-Latitude Forests, Cuizhen Wang, Aiai Wang, Dianfan Guo, Haibo Li, Shuying Zang

Faculty Publications

Collecting long-term satellite image series in high latitudes has been challenging due to its short growing season. For off-peak imagery, its reflective properties need to be corrected to maintain the spectral consistency. This study compares three statistical approaches to reconstructing a 30-year normalized difference vegetation index (NDVI) series for forest recovery assessment after the 1987 Black Dragon Fire in the Greater Hinggan Mountains Forest, Northeast China. To correct the off-peak NDVI to peak NDVI, the Landsat paired regression takes advantage of the scene-to-scene linear relationship between the two images, the GIMMS booster approach compensates the NDVI increment rate based on …

Infrastructure Decision-Making Under Climate Change Uncertainty: Case Study Of Centralized Heating At Wright-Patterson Afb, Ohio, Tyler A. Ferry, Justin D. Delorit, Christopher M. Chini

Faculty Publications

Increased prevalence, lower cost, and reduced environmental impacts have granted natural gas status as a bridge fuel over the past decade in place of coal-fired heat and power generation across the United States. As a result, some coal facilities are retrofitting their systems to combust natural gas for heating and power. However, data and economic criteria surrounding these decisions are not widely available. Wright-Patterson Air Force Base (WPAFB) invested approximately $25 million, from 2014 to 2016, to retrofit two coal-fired steam-heat-generating plants with natural gas equipment. Economic analyses used to inform these long-term infrastructure decisions rarely consider the uncertainty of …

Search For Intermediate-Mass Black Hole Binaries In The Third Observing Run Of Advanced Ligo And Advanced Virgo, Ligo Scientific Collaboration, Virgo Collaboration, Kagra Collaboration, Tiffany Z. Summerscales

Faculty Publications

Intermediate-mass black holes (IMBHs) span the approximate mass range 100−10⁵ M_⊙, between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of IMBH binaries are the most energetic gravitational-wave sources accessible by the terrestrial detector network. Searches of the first two observing runs of Advanced LIGO and Advanced Virgo did not yield any significant IMBH binary signals. In the third observing run (O3), the increased network sensitivity enabled the detection of GW190521, a signal consistent with a binary merger of mass ∼150 M_⊙ providing direct evidence of …

Several U.S. law schools offer courses in which students apply substantive legal knowledge and analysis to build functional technologies intended for real world implementation for the benefit of self-represented individuals. These courses teach students about how technology functions, its role in narrowing the access to justice gap, and fulfill many pedagogic goals …

Viscosity Of Fe-Ni-C Liquids Up To Core Pressures And Implications For Dynamics Of Planetary Cores, Feng Zhu, Xiaojing Lai, Jianwei Wang, Quentin Williams, Jiachao Liu, Yoshio Kono, Bin Chen

Faculty Publications

The viscosity of iron alloy liquids is the key for the core dynamo and core-mantle differentiation of terrestrial bodies. Here we measured the viscosity of Fe-Ni-C liquids up to 7 GPa using the floating sphere viscometry method and up to 330 GPa using first-principles calculations. We found a viscosity increase at ∼3–5 GPa, coincident with a structural transition in the liquids. After the transition, the viscosity reaches ∼14–27 mPa·s, a factor of 2–4 higher than that of Fe and Fe-S liquids. Our computational results from 5 to 330 GPa also indicate a high viscosity of the Fe-Ni-C liquids. For a …

Faculty Publications

Pastures and rangelands are a dominant portion of global agricultural land and have the potential to sequester carbon (C) in soils, mitigating climate change. Management intensive grazing (MIG), or high density grazing with rotations through paddocks with long rest periods, has been highlighted as a method of enhancing soil C in pastures by increasing forage production. However, few studies have examined the soil C storage potential of pastures under MIG in the northeastern United States, where the dairy industry comprises a large portion of agricultural use and the regional agricultural economy. Here we present a 12-year study conducted in this …

Neural Correlates Of Inhibitory Control And Associations With Cognitive Outcomes In Bangladeshi Children Exposed To Early Adversities, Eileen F. Sullivan, Wanze Xie, Stefania Conte, John E. Richards, Talat Shama, Rashidul Haque, William A. Petri, Charles A. Nelson

Faculty Publications

There is strong support for the view that children growing up in low-income homes typically evince poorer performance on tests of inhibitory control compared to those growing up in higher income homes. Unfortunately, the vast majority of the work documenting this association has been conducted in high-income countries. It is not yet known whether the mechanisms found to mediate this association would generalize to children in low- and middle-income countries, where the risks of exposure to extreme poverty and a wide range of both biological and psychosocial hazards may be greater. We examined relations among early adversity, neural correlates of …

The Ability Of Resveratrol To Attenuate Ovalbumin-Mediated Allergic Asthma Is Associated With Changes In Microbiota Involving The Gut-Lung Axis, Enhanced Barrier Function And Decreased Inflammation In The Lungs, Prakash Nagarkatti, Esraah Alharris, Hasan Alghetaa, Juhua Zhou, Mitzi Nagarkatti

Faculty Publications

Asthma is a chronic respiratory disease highly prevalent worldwide. Recent studies have suggested a role for microbiome-associated gut–lung axis in asthma development. In the current study, we investigated if Resveratrol (RES), a plant-based polyphenol, can attenuate ovalbumin (OVA)-induced murine allergic asthma, and if so, the role of microbiome in the gut–lung axis in this process. We found that RES attenuated allergic asthma with significant improvements in pulmonary functions in OVA-exposed mice when tested using plethysmography for frequency (F), mean volume (MV), specific airway resistance (sRaw), and delay time(dT). RES treatment also suppressed inflammatory cytokines in the lungs. RES modulated lung …
