A Dual-Band Filtering Structure For Highly Selective Reconfigurable Bandpass Filter And Filtering Balun, Jinqun Ge, Guoan Wang May 2022

A Dual-Band Filtering Structure For Highly Selective Reconfigurable Bandpass Filter And Filtering Balun, Jinqun Ge, Guoan Wang

Faculty Publications

This article proposes a filtering structure consisting of two half-wavelength resonators and two open-stub loaded resonators, which generates two third-order passbands. Multiple transmission zeros are introduced by the newly developed coupling scheme, resulting in extremely sharp roll-off desirable for highly selective filters. The proposed structure is applied to design a PIN-diodes switch-controlled reconfigurable dual-band bandpass filter (BPF) with four-state filtering responses: both passbands ON, both passbands OFF, high-frequency passband ON, and low-frequency passband ON. Stepped-impedance open stubs and one-end-grounded coupled lines are studied and employed in the design to suppress unwanted responses. In addition, two filtering structures are placed symmetrically …

Don't Forget The "G" In Esg: The Sec And Corporate Governance Disclosure, Jennifer O'Hare May 2022

Don't Forget The "G" In Esg: The Sec And Corporate Governance Disclosure, Jennifer O'Hare

Faculty Publications

For years, many shareholders—both institutional and individual investors—have pressured the Securities and Exchange Commission (“SEC”) to require public companies to disclose more information about the environmental, social, and governance (“ESG”) risks facing the company. However, the SEC has generally refused calls to require public corporations to disclose, for example, how they are addressing climate change or workforce diversity challenges. With a new president in the White House and a new administration at the SEC, the SEC will soon propose new ESG disclosure rules, requiring more information about the “E” and the “S” in ESG. But the SEC has forgotten the …

Estuarine and coastal geomorphology, biogeochemistry, water quality, and coastal food webs in river-dominated shelves of the Gulf of Mexico (GoM) are modulated by transport processes associated with river inputs, winds, waves, tides, and deep-ocean/continental shelf interactions. For instance, transport processes control the fate of river-borne sediments, which in turn affect coastal land loss. Similarly, transport of freshwater, nutrients, and carbon control the dynamics of eutrophication, hypoxia, harmful algal blooms, and coastal acidification. Further, freshwater inflow transports pesticides, herbicides, heavy metals, and oil into receiving estuaries and coastal systems. Lastly, transport processes along the continuum from the rivers and estuaries to …

Comparison Of Flows Through A Tidal Inlet In Late Spring And After The Passage Of An Atmospheric Cold Front In Winter Using Acoustic Doppler Profilers And Vessel-Based Observations, Mingming Li, Chunyan Li May 2022

Comparison Of Flows Through A Tidal Inlet In Late Spring And After The Passage Of An Atmospheric Cold Front In Winter Using Acoustic Doppler Profilers And Vessel-Based Observations, Mingming Li, Chunyan Li

Faculty Publications

This paper discusses the application of acoustic Doppler current profilers (ADCP) for the quantification of transport of water and the underlining physical mechanism. The transport of water through estuaries and tidal inlets is affected by tide, river flow, and wind. It is often assumed that wind effects in such systems are negligible unless under severe weather conditions. This study compares the ADCP-measured flows across a tidal inlet under weak wind conditions in late spring and those after the passage of an atmospheric cold front in winter. The Barataria Pass is a major inlet connecting Barataria Bay and northern Gulf of …

Improved Method For Testing Integrity Loss Of Wells With Sustained Casing Pressure, Mohammad Kazemi, Andrew K. Wojtanowicz May 2022

Improved Method For Testing Integrity Loss Of Wells With Sustained Casing Pressure, Mohammad Kazemi, Andrew K. Wojtanowicz

Faculty Publications

The pressure bleed-down/build-up (B/B) testing is enforced by the Bureau of Safty and Environmental Enforcement (BSEE) regulations in the US for gas-leaking wells with recurrent casing head annular pressure dubbed “Sustained Casing Pressure” (SCP). The bleed down test involves bleeding the pressure with a needle valve. Once the pressure reached to zero or stabilized, the valve is closedand a 24-h pressure monitoring starts. Analysis of the tests mandated by regulations involves merely a qualitative assessment of the low or high level of environmental risk measured by leak size. A quantitative analysis—based on mathematical models—has been already proposed and used for …

Institutional Betrayals As Sex Discrimination, Emily Suski May 2022

Institutional Betrayals As Sex Discrimination, Emily Suski

Faculty Publications

Title IX jurisprudence has a theoretical and doctrinal inadequacy. Title IX’s purpose is to protect public school students from sex discrimination in all its forms. Yet, courts have only recognized three relatively narrow forms of sex discrimination under it. Title IX jurisprudence, therefore, cannot effectively recognize as sex discrimination the independent injuries, called institutional betrayals, that schools impose on students because they have suffered sexual harassment. Institutional betrayals occur when schools betray students’ trust in or dependency on them by failing to help students in the face of their sexual harassment. These injuries cause harms that can be more severe …

References To Babe Ruth In Advocacy And Judicial Opinions, Douglas E. Abrams May 2022

References To Babe Ruth In Advocacy And Judicial Opinions, Douglas E. Abrams

Faculty Publications

The common theme of these “Writing It Right” articles is that the courts’ use of well-known cultural references in their opinions invites advocates to enhance their briefs and other submissions with references to similar well-known cultural markers. Advocates’ appropriate references to Babe Ruth, a true cultural icon, fit the bill.

On Uniqueness And Stability For The Boltzmann-Enskog Equation, Martin Friesen, Barbara Ruediger, Padmanabhan Subdar May 2022

On Uniqueness And Stability For The Boltzmann-Enskog Equation, Martin Friesen, Barbara Ruediger, Padmanabhan Subdar

Faculty Publications

The time-evolution of a moderately dense gas in a vacuum is described in classical mechanics by a particle density function obtained from the Boltzmann-Enskog equation. Based on a McKean-Vlasov equation with jumps, the associated stochastic process was recently constructed by modified Picard iterations with the mean-field interactions, and more generally, by a system of interacting particles. By the introduction of a shifted distance that exactly compensates for the free transport term that accrues in the spatially inhomogeneous setting, we prove in this work an inequality on the Wasserstein distance for any two measure-valued solutions to the Boltzmann-Enskog equation. As a …

Patterns Of Choice Adaptation In Dynamic Risky Environments, E Konstantinidis, J L. Harman, C Gonzalez May 2022

Patterns Of Choice Adaptation In Dynamic Risky Environments, E Konstantinidis, J L. Harman, C Gonzalez

Faculty Publications

An important aspect of making good decisions is the ability to adapt to changes in the values of available choice options, and research suggests that we are poor at changing behavior and adapting our choices successfully. The current paper contributes to clarifying the role of memory on learning and successful adaptation to changing decision environments. We test two aspects of changing decision environments: the direction of change and the type of feedback. The direction of change refers to how options become more or less rewarding compared to other options, over time. Feedback refers to whether full or partial information about …

Crop landraces have unique local agroecological and societal functions and offer important genetic resources for plant breeding. Recognition of the value of landrace diversity and concern about its erosion on farms have led to sustained efforts to establish ex situ collections worldwide. The degree to which these efforts have succeeded in conserving landraces has not been comprehensively assessed. Here we modelled the potential distributions of eco-geographically distinguishable groups of landraces of 25 cereal, pulse and starchy root/tuber/fruit crops within their geographic regions of diversity. We then analysed the extent to which these landrace groups are represented in genebank collections, using …

Expression Of Arylamine N-Acetyltransferase 2 Activity In Immortalized Human Bronchial Epithelial Cells, James T.F. Wise, Raúl A. Salazar-González, Mariam R. Habil, Mark A. Doll, David W. Hein

Faculty Publications

Lung cancer is the leading cause of cancer deaths in the United States with high incidence in tobacco smokers. Arylamine N-acetyltransferase 2 (NAT2) is a xenobiotic enzyme that catalyzes both N- and O-acetylation of carcinogens present in tobacco smoke and contributes towards the genotoxicity of these carcinogens. NAT2 allelic variants result in slow, intermediate, and rapid acetylation phenotypes. A recent meta-analysis reported NAT2 non-rapid (slow and intermediate) phenotypes had a significantly increased risk of lung cancer. NAT2 activity in humans is thought to be restricted to liver and gastrointestinal tract, and no studies to our knowledge have reported the expression …

Faculty Publications

Around 80% of megaflora species became extinct at the Cretaceous–Paleogene (K–Pg) boundary. Subsequent polyploidy events drove the survival of thousands of plant species and played a significant historical role in the development of the most successful modern cereal crops. However, current and rapid global temperature change poses an urgent threat to food crops worldwide, including the world’s big three cereals: rice, wheat, and maize, which are members of the grass family, Poaceae. Some minor cereals from the same family (such as teff) have grown in popularity in recent years, but there are important knowledge gaps regarding the similarities and differences …

Precise determination of ground-state feeding in the β decay of fission products is an important but challenging component in modeling reactor antineutrino flux and reactor decay heat. The Modular Total Absorption Spectrometer (MTAS) is a versatile NaI(Tl) detector array that determines the true β-decay pattern free from the pandemonium effect, including precise ground-state feeding intensities. In this paper, we report MTAS results of the β feeding intensities of Rb88 and Kr88, fission products with large cumulative yields in nuclear reactors. By comparing MTAS results with previous measurements, Rb88 provides a validation of MTAS's ability to determine ground-state feedings in β …

The Ne18(α,p)Na21 reaction plays a significant role in Type-I X-ray bursts. It is a major path in the breakout from the hot-CNO cycles to the synthesis of heavier elements in the αp- and rp-processes. An experiment to determine the cross section of this reaction was performed with the ANASEN active-target detector system, determining the cross section at energies between 2.5 and 4 MeV in the center-of-mass frame. The measured cross sections for reactions populating the ground state in Na21 are consistent with results obtained from the time-inverse reaction, but significantly lower than the previously published experimental data of direct measurements. …

Low-Efficiency Long Gamma-Ray Bursts: A Case Study With At2020blt, N. Sarin, R. Hamburg, E. Burns, G. Ashton, P. D. Lasky, G. P. Lamb May 2022

Low-Efficiency Long Gamma-Ray Bursts: A Case Study With At2020blt, N. Sarin, R. Hamburg, E. Burns, G. Ashton, P. D. Lasky, G. P. Lamb

Faculty Publications

The Zwicky Transient Facility recently announced the detection of an optical transient AT2020blt at redshift z = 2.9, consistent with the afterglow of an on-axis gamma-ray burst. However, no prompt emission was observed. We analyse AT2020blt with detailed models, showing the data are best explained as the afterglow of an on-axis long gamma-ray burst, ruling out other hypotheses such as a cocoon and a low-Lorentz factor jet. We search Fermi data for prompt emission, setting deeper upper limits on the prompt emission than in the original detection paper. Together with KONUS-Wind observations, we show that the gamma-ray efficiency of AT2020blt …

GW170817 is the only gravitational-wave event for which a confirmed 3-ray counterpart, GRB 170817A, has been detected. Here, we present a method to search for another type of 3-ray signal, a 3-ray burst precursor, associated with a compact binary merger. If emitted shortly before the coalescence, a high-energy electromagnetic (EM) flash travels through a highly dynamical and relativistic environment, created by the two compact objects orbiting each other. Thus, the EM signal arriving at an Earth observer could present a somewhat predictable time-dependent modulation. We describe a targeted search method for light curves exhibiting such a modulation, parameterized by the …

On The Spherical Slice Transform, Boris Rubin

Faculty Publications

We study the spherical slice transform which assigns to a function f on the unit sphere Sn in n+1 the integrals of f over cross-sections of Sn by k-dimensional affine planes passing through the north pole (0,..., 0, 1). These transforms are known when k = n. We consider all 2 ≤ k ≤ n and obtain an explicit formula connecting with the classical (k - 1)-plane Radon-John transform Rk-1 on n. Using this connection, known facts for Rk-1, like inversion formulas, support theorems, representation on zonal functions, and some others, are reformulated for .

Zoos and natural history museums are both collections-based institutions with important missions in biodiversity research and education. Animals in zoos are a repository and living record of the world's biodiversity, whereas natural history museums are a permanent historical record of snapshots of biodiversity in time. Surprisingly, despite significant overlap in institutional missions, formal partnerships between these institution types are infrequent. Life history information, pedigrees, and medical records maintained at zoos should be seen as complementary to historical records of morphology, genetics, and distribution kept at museums. Through examining both institution types, we synthesize the benefits and challenges of cross-institutional exchanges …

Paraphyletic Relationships Revealed By Mitochondrial Dna In The Peromyscus Mexicanus Species Group (Rodentia: Cricetidae), Giovani Hernández-Canchola, Livia León-Paniagua, Jacob A. Esselstyn

Faculty Publications

Although deer mice (Peromyscus spp.) are among the most studied small mammals, their species diversity and phylogenetic relationships remain unclear. The lack of taxonomic clarity is mainly due to a conservative morphology and because some taxa are rare, have restricted distributions, or are poorly sampled. One taxon, P. mexicanus, includes southern Mexican subspecies that have not had their systematic placement tested with genetic data. We analyzed the phylogenetic relationships and genetic structure of P. mexicanus populations using sequences of the mitochondrial gene cytochrome b. We inferred that P. mexicanus is paraphyletic, with P. m. teapensis, P. m. tehuantepecus, and P. …

Value-Added Utilization Of Wheat Straw: From Cellulose And Cellulose Nanofiber To All-Cellulose Nanocomposite Film, Hongxia Bian, Yanyan Yang, Peng Tu, Jonathan Y. Chen

Faculty Publications

To accelerate the high value-added usage of agricultural residue, cellulose and cellulose nanofibers (CNFs) were extracted from wheat straw and then formed into all-cellulose nanocomposite films. The acid–alkali method (AM) and the extraction method (EM) were respectively adopted to prepare wheat straw cellulose (WSC), and the TEMPO oxidation method was used to extract CNFs. The nanocomposite films were fabricated by dissolving WSC and adding different CNF contents of 0.0, 0.5, 1.5, and 3.0%. There was a better miscibility for the all-cellulose nanocomposite film prepared by EM (Composite-E) compared to that for the all-cellulose nanocomposite film prepared by AM (Composite-A). Composite-E …
