We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast spinning neutron stars with an asymmetry around their rotation axis, using data from the second observing run of the Advanced LIGO detectors. Three different semicoherent methods are used to search in a gravitational-wave frequency band from 20 to 1922 Hz and a first frequency derivative from -1×10-8 to 2×10-9 Hz/s. None of these searches has found clear evidence for a CW signal, so upper limits on the gravitational-wave strain amplitude are calculated, which for this broad range in parameter space are the …

Novel Salicylic Acid Analogs Induce A Potent Defense Response In Arabidopsis, Ian Arthur Palmer, Huan Chen, Jian Chen, Ming Chang, Min Li, Fengquan Liu, Zheng Qing Fu Jul 2019

Novel Salicylic Acid Analogs Induce A Potent Defense Response In Arabidopsis, Ian Arthur Palmer, Huan Chen, Jian Chen, Ming Chang, Min Li, Fengquan Liu, Zheng Qing Fu

Faculty Publications

The master regulator of salicylic acid (SA)-mediated plant defense, NPR1 (NONEXPRESSER OF PR GENES 1) and its paralogs NPR3 and NPR4, act as SA receptors. After the perception of a pathogen, plant cells produce SA in the chloroplast. In the presence of SA, NPR1 protein is reduced from oligomers to monomers, and translocated into the nucleus. There, NPR1 binds to TGA, TCP, and WRKY transcription factors to induce expression of plant defense genes. A list of compounds structurally similar to SA was generated using ChemMine Tools and its Clustering Toolbox. Several of these analogs can induce SA-mediated defense and inhibit …

Quenching Estimates For A Non-Newtonian Filtration Equation With Singular Boundary Conditions, Matthew Beauregard, Burhan Selcuk Jul 2019

Quenching Estimates For A Non-Newtonian Filtration Equation With Singular Boundary Conditions, Matthew Beauregard, Burhan Selcuk

Faculty Publications

In this paper, the quenching behavior of the non-Newtonian filtration equation (φ(u))t = (|ux| r−2 ux)x with singular boundary conditions, ux (0, t) = u −p (0, t), ux (a, t) = (1 − u(a, t))−q is investigated. Various conditions on the initial condition are shown to guarantee quenching at either the left or right boundary. Theoretical quenching rates and lower bounds to the quenching time are determined when φ(u) = u and r = 2. Numerical experiments are provided to illustrate and provide additional validation of the theoretical estimates to the quenching rates and times.

Wide-Ranging Temporal Variation In Transoceanic Movement And Population Mixing Of Bluefin Tuna In The North Atlantic Ocean, Michael A. Dance Jul 2019

Wide-Ranging Temporal Variation In Transoceanic Movement And Population Mixing Of Bluefin Tuna In The North Atlantic Ocean, Michael A. Dance

Faculty Publications

Uncertainty regarding the movement and population exchange of Atlantic bluefin tuna (Thunnus thynnus) from the two primary spawning areas (Gulf of Mexico, Mediterranean Sea) is increasingly implicated as a major impediment for the conservation of this species. Here, two mixture methods were applied to natural chemical markers (delta O-18 and delta C-13) in otoliths (ear stones) to comprehensively investigate the nature and degree of transoceanic movement and mixing of eastern and western populations in several areas of the North Atlantic Ocean that potentially represent mixing hotspots. Areas investigated occurred on both sides of the 45 degrees W management boundary as …

Evaluation Of Field Of View Width In Stereo-Vision-Based Visual Homing, Damian Lyons, Benjamin Barriage, Luca Del Signore Jul 2019

Evaluation Of Field Of View Width In Stereo-Vision-Based Visual Homing, Damian Lyons, Benjamin Barriage, Luca Del Signore

Faculty Publications

Visual homing is a local navigation technique used to direct a robot to a previously seen location by comparing the image of the original location with the current visual image. Prior work has shown that exploiting depth cues such as image scale or stereo-depth in homing leads to improved homing performance. While it is not unusual to use a panoramic field of view (FOV) camera in visual homing, it is unusual to have a panoramic FOV stereo-camera. So, while the availability of stereo-depth information may improve performance, the concomitant-restricted FOV may be a detriment to performance, unless specialized stereo hardware …

New Constraints On Early-Type Galaxy Assembly From Spectroscopic Metallicities Of Globular Clusters In M87, Alexa Villaume, Aaron Romanowsky, Jean Brodie, Jay Strader Jul 2019

New Constraints On Early-Type Galaxy Assembly From Spectroscopic Metallicities Of Globular Clusters In M87, Alexa Villaume, Aaron Romanowsky, Jean Brodie, Jay Strader

Faculty Publications

The observed characteristics of globular cluster (GC) systems, such as metallicity distributions, are commonly used to place constraints on galaxy formation models. However, obtaining reliable metallicity values is particularly difficult because of our limited means to obtain high quality spectroscopy of extragalactic GCs. Often, "color–metallicity relations" are invoked to convert easier-to-obtain photometric measurements into metallicities, but there is no consensus on what form these relations should take. In this paper we make use of multiple photometric data sets and iron metallicity values derived from applying full-spectrum stellar population synthesis models to deep Keck/LRIS spectra of 177 GCs centrally located around …

The Roussopoulos And Schwinger Functionals For Nuclear Systems Involving Imprecisely Known Fluxes And Parameters: Distinctions And Equivalences, Dan Gabriel Cacuci Jul 2019

The Roussopoulos And Schwinger Functionals For Nuclear Systems Involving Imprecisely Known Fluxes And Parameters: Distinctions And Equivalences, Dan Gabriel Cacuci

Faculty Publications

For over 60 years, the Roussopoulos and Schwinger functionals have been used in many works and textbooks under the assumption that they provide “second-order accurate” trial functions for the forward and adjoint fluxes when computing reaction rates and/or particle detector responses in source-driven nuclear systems. The Schwinger functional has been employed as a particularly useful form of the Roussopoulos functional for systems in which the forward and adjoint particle fluxes were normalized. When using these functionals, however, the expressions for the approximate fluxes were postulated arbitrarily while the system parameters were unrealistically assumed to be perfectly well known. This work …

Faculty Publications

Patients entering an inpatient psychiatry program (N = 406) with co-occurring mental health and substance use disorders reported on their social support networks (source, type) at treatment intake, and completed symptom measures at baseline and 3-, 9-, and 15-month follow-ups (77%). Longitudinal growth models found aspects of participants’ support networks were associated with specific symptoms over time. Less family support (i.e., more conflict) was the most consistent predictor of mental health and substance use outcomes and was associated with greater psychiatric, depression, Post Traumatic Stress Disorder (PTSD), and drug use severity. More peer support (via mutual-help involvement) was associated with …

Towards Lakosian Multilingual Software Design Principles, Damian Lyons, Saba Zahra, Thomas Marshall Jul 2019

Towards Lakosian Multilingual Software Design Principles, Damian Lyons, Saba Zahra, Thomas Marshall

Faculty Publications

Large software systems often comprise programs written in different programming languages. In the case when cross-language interoperability is accomplished with a Foreign Function Interface (FFI), for example pybind11, Boost.Python, Emscripten, PyV8, or JNI, among many others, common software engineering tools, such as call-graph analysis, are obstructed by the opacity of the FFI. This complicates debugging and fosters potential inefficiency and security problems. One contributing issue is that there is little rigorous software design advice for multilingual software. In this paper, we present our progress towards a more rigorous design approach to multilingual software. The approach is based on the existing …

Improving The Transferability Of Suspended Solid Estimation In Wetland And Deltaic Waters With An Empirical Hyperspectral Approach, Daniel Jensen, Marc Simard, Kyle Cavanaugh, Yongwei Sheng, Cédric G. Fichot, Tamlin Pavelsky, Robert Twilley Jul 2019

Improving The Transferability Of Suspended Solid Estimation In Wetland And Deltaic Waters With An Empirical Hyperspectral Approach, Daniel Jensen, Marc Simard, Kyle Cavanaugh, Yongwei Sheng, Cédric G. Fichot, Tamlin Pavelsky, Robert Twilley

Faculty Publications

The deposition of suspended sediment is an important process that helps wetlands accrete surface material and maintain elevation in the face of sea level rise. Optical remote sensing is often employed to map total suspended solids (TSS), though algorithms typically have limited transferability in space and time due to variability in water constituent compositions, mixtures, and inherent optical properties. This study used in situ spectral reflectances and their first derivatives to compare empirical algorithms for estimating TSS using hyperspectral and multispectral data. These algorithms were applied to imagery collected by NASA’s Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) over coastal Louisiana, …

Improving Prediction Accuracy In Building Performance Models Using Generative Adversarial Networks (Gans), Chanachok Chokwitthaya, Edward Collier, Yimin Zhu, Supratik Mukhopadhyay Jul 2019

Improving Prediction Accuracy In Building Performance Models Using Generative Adversarial Networks (Gans), Chanachok Chokwitthaya, Edward Collier, Yimin Zhu, Supratik Mukhopadhyay

Faculty Publications

Building performance discrepancies between building design and operation are one of the causes that lead many new designs fail to achieve their goals and objectives. A main factor contributing to the discrepancy is occupant behaviors. Occupants responding to a new design are influenced by several factors. Existing building performance models (BPMs) ignore or partially address those factors (called contextual factors) while developing BPMs. To potentially reduce the discrepancies and improve the prediction accuracy of BPMs, this paper proposes a computational framework for learning mixture models by using Generative Adversarial Networks (GANs) that appropriately combining existing BPMs with knowledge on occupant …

The Case For Doing Nothing About Institutional Investors' Common Ownership Of Small Stakes In Competing Firms, Thomas A. Lambert, Michael E. Sykuta Jul 2019

The Case For Doing Nothing About Institutional Investors' Common Ownership Of Small Stakes In Competing Firms, Thomas A. Lambert, Michael E. Sykuta

Faculty Publications

Recent empirical research purports to demonstrate that institutional investors' "common ownership " of small stakes in competing firms causes those firms to compete less aggressively, injuring consumers. A number of prominent antitrust scholars have cited this research as grounds for limiting the degree to which institutional investors may hold stakes in multiple firms that compete in any concentrated market. This Article contends that the purported competitive problem is overblown and that the proposed solutions would reduce overall social welfare. With respect to the purported problem, we show that the theory of anti-competitive harm from institutional investors' common ownership is implausible …

British Impeachments (1376-1787) And The Preservation Of The American Constitutional Order, Frank O. Bowman Iii Jul 2019

British Impeachments (1376-1787) And The Preservation Of The American Constitutional Order, Frank O. Bowman Iii

Faculty Publications

Impeachment is a British invention, employed by Parliament beginning in 1376 to resist the general tendency of the monarchy to absolutism and to counter particularly obnoxious royal policies by removing the ministers who implemented them. The invention crossed the Atlantic with the British colonists who would one day rebel against their mother country and create an independent United States of America. During the Constitutional Convention of 1787, the delegates decided that presidents and other federal officers could be impeached, but they recoiled from the severe and occasionally fatal punishments imposed by Parliament, and they wrestled over what conduct should be …

Moving Beyond Medical Debt, Brook E. Gotberg, Michael D. Sousa Jul 2019

Moving Beyond Medical Debt, Brook E. Gotberg, Michael D. Sousa

Faculty Publications

In recent years it has become clear that medical costs are imposing severe financial burdens on American families, sometimes to the point that bankruptcy becomes the only escape from crippling debt. When evaluating the well-established connection between outstanding medical debt and consumer bankruptcy, most existing empirical studies attempt to quantify the percentage of consumer bankruptcies that are "caused" by unmanageable medical indebtedness. This Article addresses what we believe to be a more significant line of empirical inquiry, namely, the connection between health insurance coverage and consumer bankruptcy as a more precise measurement of how national health insurance programs may or …
