The Quiet Undoing: How Regional Electricity Market Reforms Threaten Clean Energy Goals, Shelley Welton, Danny Cullenward

Faculty Publications

In a series of largely unnoticed but extremely consequential moves, two regional electricity market operators are pursuing reforms to make it more difficult for states to achieve their clean energy goals. The federal energy regulator, FERC, has already approved one such reform and ordered a second market operator to go farther in punishing state-supported clean energy resources than it had initially proposed. In this Essay, we bring to light the ways in which the intricate, technical reforms underway in regional electricity markets threaten state climate change objectives and the durability of FERC’s regional market constructs. If FERC allows private market …

The Role Of Ict In Antiretroviral Therapy-Related Knowledge Seeking Among Older Chinese Living With Hiv, Yao Zhang, Xiaoming Li Ph.D., Shan Qiao Ph.D., Yuejiao Zhou, Zhiyong Shen

Faculty Publications

Antiretroviral therapy (ART) enables HIV patients to reduce disease progression. ART adherence is closely related to patients’ knowledge about the medical treatment. This study investigated the role of information and communication technologies (ICTs) in supporting ART-related knowledge seeking among older Chinese with HIV, using cross-sectional data collected from 2012 to 2013 in Guangxi, China. Of the 2987 HIV patients, 688 were 45 years or older and going through ART. We used an 11-item scale (α=0.69), which was developed based on existing literature, to assess ART-related knowledge to obtain a composite score (0-11). Less than 5% of the participants sought HIV-related …

Skin-like sensory devidces shoud be stretchable and self-healable to meet the demands for future electronic skin applications. Despite recent notable advances in skin-inspired electronic materials, it remains challenging to confer these desired functionalities to an active semiconductor. Here, we report a strain-sensitive, stretchable, and autonomously self-healable semiconducting film achieved through blending of a polymer semiconductor and a self-healable elastomer, both of which are dynamically cross-linked by metal coordination. We observed that by controlling the percolation threshold of the polymer semiconductor, the blend film became strain sensitive, with a gauge factor of 5.75 x 10⁵ at 100% strain in a …

Critical Field Behavior Of A Multiply Connected Superconductor In A Tilted Magnetic Field, F. N. Womack, P. W. Adams, J. M. Valles, G. Catelani

Faculty Publications

We report magnetotransport measurements of the critical field behavior of thin Al films deposited onto multiply connected substrates. The substrates were fabricated via a standard electrochemical process that produced a triangular array of 66-nm-diameter holes having a lattice constant of 100 nm. The critical field transition of the Al films was measured near Tc as a function of field orientation relative to the substrate normal. With the field oriented along the normal (θ=0), we observe reentrant superconductivity at a characteristic matching field Hm=0.22 T, corresponding to one flux quantum per hole. In tilted fields, the position H∗ of the reentrance …

A Review Of 30 Years Of Research Using The Cpd Model, Thomas H. Fletcher

Faculty Publications

The chemical percolation devolatilization (CPD) model for coal pyrolysis was first published in 1989, and a completed version that included the vapor–liquid equilibrium model and cross-linking model was published in 1992. The CPD model was one of three pyrolysis models developed using a lattice model to account for the chemical structure of the coal and was directly based on solid-state ¹³C nuclear magnetic resonance (NMR) measurements of the coal structure. A correlation of coal structure parameters measured by NMR spectroscopy was performed to permit use of the CPD model to determine pyrolysis rates and yields of tars and light …

Addressing The Gap In Consumer Protection For Small Business Consumers Through A Multiple Method Research Program, Glenn L. Christensen, Sterling A. Bone, Jerome D. Williams

Faculty Publications

For more than a decade we, as academic researchers, have investigated the experience of small business customers seeking financial products for their businesses. We have employed a variety of research methodologies to explore the “lived” experiences of small business owners seeking financing, including matched-paired mystery shopping, video ethnography, depth-interviews, controlled experiments, and surveys. From this research, we show that with limited financial sophistication, entrepreneurial small-business consumers approach the financial marketplace much more like retail financial consumers than sophisticated, corporate customers. Furthermore, we find that the customer service received by these small business customers seeking small business bank loan products is …

Analysis Of The Cody Rnome Reveals Rsad As A Stress-Responsive Riboregulator Of Overflow Metabolism In Staphylococcus Aureus, Yoann Augagneur, Alyssa N. King, Noëlla Germain-Amiot, Mohamed Sassi, John W. Fitzgerald, Gyan S. Sahukhal, Mohamed O. Elasri, Brice Felden, Shaun R. Brinsmade

Faculty Publications

In Staphylococcus aureus, the transcription factor CodY modulates the expression of hundreds of genes, including most virulence factors, in response to the availability of key nutrients like GTP and branched‐chain amino acids. Despite numerous studies examining how CodY controls gene expression directly or indirectly, virtually nothing is known about the extent to which CodY exerts its effect through small regulatory RNAs (sRNAs). Herein, we report the first set of sRNAs under the control of CodY. We reveal that staphylococcal sRNA RsaD is overexpressed >20‐fold in a CodY‐deficient strain in three S. aureus clinical isolates and in S. epidermidis. …

© 2019 National Academy of Sciences. All rights reserved. Single-cell RNA sequencing of cells from cultured human blastocysts has enabled us to define the transcriptomic landscape of placental trophoblast (TB) that surrounds the epiblast and associated embryonic tissues during the enigmatic day 8 (D8) to D12 peri-implantation period before the villous placenta forms. We analyzed the transcriptomes of 3 early placental cell types, cytoTB (CTB), syncytioTB (STB), and migratoryTB (MTB), picked manually from cultured embryos dissociated with trypsin and were able to follow sublineages that emerged from proliferating CTB at the periphery of the conceptus. A unique form of CTB …

A Deda Family Membrane Protein Is Required For Burkholderia Thailandensis Colistin Resistance, Pradip R. Panta, Sujeet Kumar, Caroline F. Stafford, Caitlin E. Billiot, Martin V. Douglass, Carmen M. Herrera, M. Stephen Trent, William T. Doerrler

Faculty Publications

© Copyright © 2019 Panta, Kumar, Stafford, Billiot, Douglass, Herrera, Trent and Doerrler. Colistin is a “last resort” antibiotic for treatment of infections caused by some multidrug resistant Gram-negative bacterial pathogens. Resistance to colistin varies between bacterial species. Some Gram-negative bacteria such as Burkholderia spp. are intrinsically resistant to very high levels of colistin with minimal inhibitory concentrations (MIC) often above 0.5 mg/ml. We have previously shown DedA family proteins YqjA and YghB are conserved membrane transporters required for alkaline tolerance and resistance to several classes of dyes and antibiotics in Escherichia coli. Here, we show that a DedA family …

Organophilic, Superparamagnetic, And Reversibly Thermoresponsive Silica-Polypeptide Core-Shell Particles, Sibel Turksen-Selcuk, Cornelia Rosu, Alyssa Blake, Erick Soto-Cantu, Jianhong Qiu, Yan Wu, J. F. Ditusa, Amanda Steffens, Paul S. Russo

Faculty Publications

Particles with a superparamagnetic cobalt inner core, silica outer core, and covalently bound homopolypeptide shell were investigated under thermal and magnetic stimuli. The homopolypeptide was poly(ϵ-carbobenzyloxy-l-lysine), PCBL, which is known to exhibit a thermoreversible coil → helix transition when dissolved as a pure polymer in m-cresol. Tethering to a core particle did not prevent PCBL from undergoing this conformational transition, as confirmed by dynamic light scattering and optical rotation, but the transition was broadened compared to that of the untethered polymer. The Co@SiO2-PCBL hybrid particles retained the superparamagnetic properties of the cobalt inner nougat. Indeed, some response remains even after …

Influence Of Magnetism On Dirac Semimetallic Behavior In Nonstoichiometric Sr1-Ymn1-Zsb2 (Y∼0.07,Z∼0.02), Qiang Zhang, Satoshi Okamoto, Matthew B. Stone, Jinyu Liu, Yanglin Zhu, John Ditusa, Zhiqiang Mao, David Alan Tennant

Faculty Publications

Nonstoichiometric Sr1-yMn1-zSb2(y,z<0.1) is known to exhibit a coexistence of magnetic order and the nontrivial semimetallic behavior. In this paper, we report the magnetism and its strong coupling to the semimetallic behavior, by a combined use of inelastic neutron scattering (INS) and density functional theory (DFT). A phase separation consisting of a majority antiferromagentic phase and a minority ferromagnetic phase is proposed. We found a relatively large spin excitation gap ≈8.5meV at 5 K, and the interlayer magnetic exchange constant only 2.8% of the dominant intralayer magnetic interaction, evidencing a quasi-2D magnetism in Sr1-yMn1-zSb2. Using DFT, we find a strong influence of magnetic orders on the electronic band structure and the Dirac dispersions near the Fermi level along the Y-S direction in the presence of a ferromagnetic order. Furthermore, we demonstrate that the size of the ferromagnetic ordered moment is an effective strategy to tune Dirac/Weyl dispersions near the Fermi level. Our study unveils novel interplay between the magnetic order, ordered moment, and electronic band topology in Sr1-yMn1-zSb2 and opens pathways to control the relativistic band structure.

Towards Overcoming The Curse Of Dimensionality: The Third-Order Adjoint Method For Sensitivity Analysis Of Response-Coupled Linear Forward/Adjoint Systems, Uncertainty Quantification And Predictive Modeling With Applications To Nuclear Energy Systems, Dan Gabriel Cacuci

Faculty Publications

This work presents the Third-Order Adjoint Sensitivity Analysis Methodology (3rd-ASAM) for response-coupled forward and adjoint linear systems. The 3rd-ASAM enables the efficient computation of the exact expressions of the 3rd-order functional derivatives (“sensitivities”) of a general system response, which depends on both the forward and adjoint state functions, with respect to all of the parameters underlying the respective forward and adjoint systems. Such responses are often encountered when representing mathematically detector responses and reaction rates in reactor physics problems. The 3rd-ASAM extends the 2nd-ASAM in the quest to overcome the “curse of dimensionality” in sensitivity analysis, uncertainty quantification and predictive …

Comprehensive Second-Order Adjoint Sensitivity Analysis Methodology (2nd-Asam) Applied To A Subcritical Experimental Reactor Physics Benchmark: I. Effects Of Imprecisely Known Microscopic Total And Capture Cross Sections, Daniel Gabriel Cacuci, Ruixian Fang, Jeffrey A. Favorite

Faculty Publications

The subcritical polyethylene-reflected plutonium (PERP) metal fundamental physics benchmark, which is included in the Nuclear Energy Agency (NEA) International Criticality Safety Benchmark Evaluation Project (ICSBEP) Handbook, has been selected to serve as a paradigm illustrative reactor physics system for the application of the Second-Order Adjoint Sensitivity Analysis Methodology (2nd-ASAM) that was developed by Cacuci. The 2nd-ASAM enables the exhaustive deterministic computation of the exact values of the 1st-order and 2nd-order sensitivities of a system response to the parameters underlying the respective system. The PERP benchmark is numerically modeled in this work by using the deterministic multigroup neutron transport equation discretized …

A Comparison Of Contextual Bandit Approaches To Human-In-The-Loop Robot Task Completion With Infrequent Feedback, Matt Mcneill, Damian Lyons

Faculty Publications

Artificially intelligent assistive agents are playing an increased role in our work and homes. In contrast with currently predominant conversational agents, whose intelligence derives from dialogue trees and external modules, a fully autonomous domestic or workplace robot must carry out more complex reasoning. Such a robot must make good decisions as soon as possible, learn from experience, respond to feedback, and rely on feedback only as much as necessary. In this research, we narrow the focus of a hypothetical robot assistant to a room tidying task in a simulated domestic environment. Given an item, the robot chooses where to put …

Gulf Of Mexico Hypoxia: Past, Present, And Future, Nancy N. Rabalais, R. Eugene Turner

Faculty Publications

One of the largest human-caused areas of bottom-water oxygen deficiency in the coastal ocean is on the northern Gulf of Mexico continental shelf adjacent to the Mississippi River, which discharges nitrogen and phosphorus loads into its surface waters. The beginnings of seasonal hypoxia (≤2 mg l−1 dissolved oxygen) in this area was in the 1950s with an acceleration in the worsening of severity during the 1970s. Currently, the bottom area of hypoxic areas can approach 23,000 km2, and the volume, 140 km3. Ecosystems, people, and economies are now at risk within the Mississippi River watershed and in the northern Gulf …

Integrating Imaging Spectrometer And Synthetic Aperture Radar Data For Estimating Wetland Vegetation Aboveground Biomass In Coastal Louisiana, Daniel Jensen, Kyle C. Cavanaugh, Marc Simard, Gregory S. Okin, Edward Castañeda-Moya, Annabeth Mccall, Robert R. Twilley

Faculty Publications

Aboveground biomass (AGB) plays a critical functional role in coastal wetland ecosystem stability, with high biomass vegetation contributing to organic matter production, sediment accretion potential, and the surface elevation's ability to keep pace with relative sea level rise. Many remote sensing studies have employed either imaging spectrometer or synthetic aperture radar (SAR) for AGB estimation in various environments for assessing ecosystem health and carbon storage. This study leverages airborne data from NASA's Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) and Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) to assess their unique capabilities in combination to estimate AGB in coastal deltaic wetlands. …

Combining Context-Aware Design-Specific Data And Building Performance Models To Improve Building Performance Predictions During Design, Chanachok Chokwitthaya, Y. Zhu, Robert Dibiano, Supratik Mukhopadhyay

Faculty Publications

Building performance models (BPMs) such as building energy simulation models have been widely used in building design. Conventional BPMs may not be able to effectively address human- building interactions in new buildings still under design. The lack of such capability often contributes to the existence of building performance gaps, i.e., differences between predicted performance during design and actual performance of buildings. To improve the prediction accuracy of conventional BPMs, a computational framework is developed. It combines an existing BPM with context-aware design-specific data involving human-building interactions in new designs, using a machine learning approach. Immersive virtual environment (IVE) is used …

Faculty Publications

Building energy simulation plays an increasingly important role in building design and operation. This paper presents an open computing infrastructure, Virtual Information Fabric Infrastructure (VIFI), that allows building designers and engineers to enhance their simulations by combining empirical data with diagnostic or prognostic models. Based on the idea of dynamic data-driven application systems (DDDAS), the VIFI infrastructure complements conventional data-centric sharing strategies and addresses key data-sharing concerns such as the privacy of building occupants. To demonstrate the potential of the VIFI infrastructure, an empirically derived lighting schedule in the US Department of Energy's small office building reference model is simulated. …

Sales Order Backlog And Corporate Social Responsibility, Li Sun, Brian Walkup, Kean Wu

Faculty Publications

We examine the impact of sales order backlog, an important leading indicator of firm performance, on corporate social responsibility (CSR) performance (measured as responsible and irresponsible CSR performance). We rely on the stakeholder view and the resource availability view of CSR to develop our hypotheses. Under the stakeholder view, we posit a positive relation between sales order backlog and CSR performance. Under the resource availability view, we posit this relationship to be negative. Our empirical evidence shows a significant positive relation between order backlog and irresponsible CSR performance, suggesting that firms with higher order backlog demonstrate lower overall CSR performance. …

Dark Matter And No Dark Matter: On The Halo Mass Of Ngc 1052, Duncan Forbes, Adebusola Alabi, Jean Brodie, Aaron Romanowsky

Faculty Publications

The NGC 1052 group, and in particular the discovery of two ultra-diffuse galaxies with very low internal velocity dispersions, has been the subject of much attention recently. Here we present radial velocities for a sample of 77 globular clusters associated with NGC 1052 obtained on the Keck telescope. Their mean velocity and velocity dispersion are consistent with that of the host galaxy. Using a simple tracer mass estimator, we infer the enclosed dynamical mass and dark matter fraction of NGC 1052. Extrapolating our measurements with a Navarro–Frenk–White (NFW) mass profile we infer a total halo mass of 6.2(±0.2) × 1012 …

The Fourth Amendment’s prohibition of “unreasonable searches” is one of the most storied constitutional commands Yet after decades of Supreme Court jurisprudence, a coherent definition of the term “search” remains surprisingly elusive Even the justices know they have a problem Recent opinions only halfheartedly apply the controlling “reasonable expectation of privacy” test and its wildly unpopular cousin, “third-party doctrine,” with a few justices in open revolt.

These fissures hint at the Court’s openness to a new approach Unfortunately, no viable alternatives appear on the horizon The justices themselves offer little in the way of a replacement And scholars’ proposals exhibit …

Atmospheric Carbon Monoxide Oxidation Is A Widespread Mechanism Supporting Microbial Survival, Paul R.F. Cordero, Katherine Bayly, Pok Man Leung, Cheng Huang, Zahra F. Islam, Ralf B. Schittenhelm, Gary M. King, Chris Greening

Faculty Publications

© 2019, The Author(s). Carbon monoxide (CO) is a ubiquitous atmospheric trace gas produced by natural and anthropogenic sources. Some aerobic bacteria can oxidize atmospheric CO and, collectively, they account for the net loss of ~250 teragrams of CO from the atmosphere each year. However, the physiological role, genetic basis, and ecological distribution of this process remain incompletely resolved. In this work, we addressed these knowledge gaps through culture-based and culture-independent work. We confirmed through shotgun proteomic and transcriptional analysis that the genetically tractable aerobic soil actinobacterium Mycobacterium smegmatis upregulates expression of a form I molydenum–copper carbon monoxide dehydrogenase by …

MicroRNAs modulate a variety of cellular events, including skeletal muscle development, but the molecular basis of their functions in fetal bovine skeletal muscle development is poorly understood. In this study, we report that bta-miR-24-3p promotes the myogenic differentiation of fetal bovine PDGFRα- progenitor cells. The expression of bta-miR-24-3p increased during myogenic differentiation. Overexpression of bta-miR-24-3p significantly promoted myogenic differentiation, but inhibited proliferation. A dual-luciferase assay identified ACVR1B as a direct target of bta-miR-24-3p. Similarly, knocking down ACVR1B by RNA interference also significantly inhibited proliferation and promoted the differentiation of bovine PDGFRα- …
