States Can Infringe Upon Your Intellectual Property Rights With Impunity In The Era Of "New Federalism", Homayoon Rafatijo, Dennis D. Crouch Apr 2022

States Can Infringe Upon Your Intellectual Property Rights With Impunity In The Era Of "New Federalism", Homayoon Rafatijo, Dennis D. Crouch

Faculty Publications

Antagonized by half a century of insouciance toward federalism boundaries, the "New Federalism" revival began under Chief Justice Rehnquist. As part of this revival, the Rehnquist Court substantially restrained Congress's authority to regulate commerce, abrogate sovereign immunity, fashion remedies pursuant to Section 5 of the Fourteenth Amendment, and "commandeer" state officials. The New Federalism has continued in the Roberts Court Era, most recently in a case weighing congressionally enacted copyright policy against the sovereignty of individual states to disregard copyright. In Allen v. Cooper, a unanimous Supreme Court held that Congress's express power under Article I is not a …

Search For Gravitational Waves Associated With Gamma-Ray Bursts Detected By Fermi And Swift During The Ligo-Virgo Run O3b, R. Abbott

Faculty Publications

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC-2020 March 27 17:00 UTC). We conduct two independent searches: a generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence …

Artificial Intelligence For The Discovery Of Novel Antimicrobial Agents For Emerging Infectious Diseases, A Bess, F Berglind, S Mukhopadhyay, M Brylinski, A Bess, T F. Cho, C Galliano, K M. Wasan

Faculty Publications

The search for effective drugs to treat new and existing diseases is a laborious one requiring a large investment of capital, resources, and time. The coronavirus 2019 (COVID-19) pandemic has been a painful reminder of the lack of development of new antimicrobial agents to treat emerging infectious diseases. Artificial intelligence (AI) and other in silico techniques can drive a more efficient, cost friendly approach to drug discovery by helping move potential candidates with better clinical tolerance forward in the pipeline. Several research teams have developed successful AI platforms for hit identification, lead generation, and lead optimization. In this review, we …

The Effects Of Microtubule Stabilizing And Recovery Agents On Vitrified Bovine Oocytes, Emily Girka, Lauren Gatenby, Emilio J. Gutierrez, Kenneth R. Bondioli

Faculty Publications

Oocyte vitrification, while beneficial for research and species conservation applications, has limited success due to cryoinjury to the meiotic spindle. This study aimed to improve meiotic spindle recovery in vitrified bovine oocytes by investigating the effects of treatment with either a microtubule stabilizing agent, or a microtubule recovery agent. In the first two experiments, either paclitaxel or epothilone B were used to treat bovine oocytes before vitrification. Both compounds have microtubule stabilizing properties and are known antimitotic compounds used to disrupt microtubule dynamics in rapidly proliferating cancer cells. Paclitaxel treatment at 2.0 μM significantly increased the proportion of oocytes with …

The horn fly, Haematobia irritans, is a blood-feeding parasitic fly with a global distribution that includes Europe, Africa, Asia, and the Americas. The fly has a major detrimental economic impact upon cattle production, with losses estimated at over $800 million annually in the United States and $2.5 billion in Brazil alone. Insecticide resistance in specific horn fly populations has been a problem for many years and there are several mechanisms whereby resistance develops. Little is known about the complement of metabolic enzymes encoded by the horn fly's genome that might provide the fly with detoxification or sequestration pathways to survive …

Molecular Characterization And Expression Variation Of The Odorant Receptor Co-Receptor In The Formosan Subterranean Termite, Paula Castillo, Claudia Husseneder, Qian Sun Apr 2022

Molecular Characterization And Expression Variation Of The Odorant Receptor Co-Receptor In The Formosan Subterranean Termite, Paula Castillo, Claudia Husseneder, Qian Sun

Faculty Publications

Subterranean termites live in underground colonies with a division of labor among castes (i.e., queens and kings, workers, and soldiers). The function of social colonies relies on sophisticated chemical communication. Olfaction, the sense of smell from food, pathogens, and colony members, plays an important role in their social life. Olfactory plasticity in insects can be induced by long- and short-term environmental perturbations, allowing adaptive responses to the chemical environment according to their physiological and behavioral state. However, there is a paucity of information on the molecular basis of olfaction in termites. In this study, we identified an ortholog encoding the …

The genus Phyllachora contains numerous obligate fungal parasites that produce raised, melanized structures called stromata on their plant hosts referred to as tar spot. Members of this genus are known to infect many grass species but generally do not cause significant damage or defoliation, with the exception of P. maydis which has emerged as an important pathogen of maize throughout the Americas, but the origin of this pathogen remains unknown. To date, species designations for Phyllachora have been based on host associations and morphology, and most species are assumed to be host specific. We assessed the sequence diversity of 186 …

A Nondestructive Method Of Calculating The Wing Area Of Insects, Kexin Yu, Gadi V.P. Reddy, Julian Schrader, Xuchen Guo, Yirong Li, Yabing Jiao, Peijian Shi Apr 2022

A Nondestructive Method Of Calculating The Wing Area Of Insects, Kexin Yu, Gadi V.P. Reddy, Julian Schrader, Xuchen Guo, Yirong Li, Yabing Jiao, Peijian Shi

Faculty Publications

Most insects engage in winged flight. Wing loading, that is, the ratio of body mass to total wing area, has been demonstrated to reflect flight maneuverability. High maneuverability is an important survival trait, allowing insects to escape natural enemies and to compete for mates. In some ecological field experiments, there is a need to calculate the wing area of insects without killing them. However, fast, nondestructive estimation of wing area for insects is not available based on past work. The Montgomery equation (ME), which assumes a proportional relationship between leaf area and the product of leaf length and width, is …

Do Mobile Consumers Homogenize The Distribution Of Resources In Stream Food Webs? A Test With Overlapping Fish And Mussel Aggregations, Caryn C. Vaughn, Thomas B. Parr, Traci P. Dubose, Kiza K. Gates, Garrett W. Hopper, Keith B. Gido Apr 2022

Do Mobile Consumers Homogenize The Distribution Of Resources In Stream Food Webs? A Test With Overlapping Fish And Mussel Aggregations, Caryn C. Vaughn, Thomas B. Parr, Traci P. Dubose, Kiza K. Gates, Garrett W. Hopper, Keith B. Gido

Faculty Publications

In streams, unionoid mussels and fish form aggregations that exert bottom-up and top-down effects on food webs, but the magnitude and spatial extent of their effects are controlled by species traits. Sedentary mussels live burrowed in the sediment in patchily distributed dense aggregations (mussel beds) where they filter seston and provide a local, relatively constant nutrient subsidy. In contrast, fish move on and off mussel beds, and thus comprise a transient nutrient subsidy. We asked how overlap between fish and mussels influences nutrient recycling and resource distribution in streams. We conducted an 8-week study in experimental streams where we created …

Faculty Publications

Refugees’ successful integration into US society requires adaptation to economic, financial and social norms. Despite the importance of considering financial challenges (financial stress and financial anxiety) and financial capacity (financial literacy and financial self-efficacy) in reaching personal financial goals, literature examining the relationship between financial challenges and capacity—critical in refugee resettlement and integration—is sparse and fragmented. This study explored financial challenges and capacity amongst resettled African refugees (N ¼ 130) in the southern USA using data from a larger community-based participatory research study that used a mixed-methods approach. We explored socio-demographic differences in financial stress, financial anxiety, financial literacy and …

Faculty Publications

The Separator for Capture Reactions (SECAR) is a next-generation recoil separator system at the Facility for Rare Isotope Beams (FRIB) designed for the direct measurement of capture reactions on unstable nuclei in inverse kinematics. To maximize the performance of this system, stringent requirements on the beam alignment to the central beam axis and on the ion-optical settings need to be achieved. These can be difficult to attain through manual tuning by human operators without potentially leaving the system in a suboptimal and irreproducible state. In this work, we present the first development of online Bayesian optimization with a Gaussian process …

Simulating Neutron Star Mergers With The Lagrangian Numerical Relativity Code Sphincs_Bssn, Peter Diener, Stephan Rosswog, Francesco Torsello Apr 2022

Simulating Neutron Star Mergers With The Lagrangian Numerical Relativity Code Sphincs_Bssn, Peter Diener, Stephan Rosswog, Francesco Torsello

Faculty Publications

We present the first neutron star merger simulations performed with the newly developed Numerical Relativity code SPHINCS_BSSN. This code evolves the spacetime on a mesh using the BSSN formulation, but matter is evolved via Lagrangian particles according to a high-accuracy version of general-relativistic Smooth Particle Hydrodynamics (SPH). Our code contains a number of new methodological elements compared to other Numerical Relativity codes. The main focus here is on the new elements that were introduced to model neutron star mergers. These include (a) a refinement (fixed in time) of the spacetime-mesh, (b) corresponding changes in the particle–mesh mapping algorithm and (c) …

Even-Even Nd Isotopes In An Sd -Pair Shell Model, B. C. He, S. Y. Zhang, Lei Li, Y. A. Luo, Y. Zhang, F. Pan, J. P. Draayer Apr 2022

Even-Even Nd Isotopes In An Sd -Pair Shell Model, B. C. He, S. Y. Zhang, Lei Li, Y. A. Luo, Y. Zhang, F. Pan, J. P. Draayer

Faculty Publications

Nucleon pair shell model truncated to SD collective pair subspace (SDPSM) was applied to study the properties of the low-lying states of the even-even Nd144-156 isotopes. It is found that, within the M scheme, the systems with the number Nν=7 of neutron pairs (or the number Nπ=7 of proton pairs) can be studied in the SDPSM for the first time. The results show that the properties of the low-lying states of the even-even Nd isotopes can be reproduced approximately, and the even-even Nd144-156 isotopes may be a good candidate for the first-order shape phase transition.

Imidazolium-Type Anion Exchange Membranes For Improved Organic Acid Transport And Permselectivity In Electrodialysis, Matthew L. Jordan, Tanmay Kulkarni, Dodangodage Ishara Senadheera, Revati Kumar, Yupo J. Lin, Christopher G. Arges Apr 2022

Imidazolium-Type Anion Exchange Membranes For Improved Organic Acid Transport And Permselectivity In Electrodialysis, Matthew L. Jordan, Tanmay Kulkarni, Dodangodage Ishara Senadheera, Revati Kumar, Yupo J. Lin, Christopher G. Arges

Faculty Publications

Most commercial anion exchange membranes (AEMs) deploy quaternary ammonium moieties. Alternative cation moieties have been explored in AEMs for fuel cells, but there are no studies focused examining alternative tethered cations in AEMs for ionic separations-such as organic acid anion transport via electrodialysis. H-cell and conductivity experiments demonstrate that tethered benzyl 1-methyl imidazolium groups in polysulfone AEMs enhance lactate conductivity by 49% and improved lactate anion flux by 24x when compared to a quaternary benzyl ammonium polysulfone AEM. An electrodialysis demonstration with the imidazolium-type AEM showed a 2x improvement in lactate anion flux and 20% improvement in permselectivity when benchmarked …

Before the Perseverance rover landing, the acoustic environment of Mars was unknown. Models predicted that: (1) atmospheric turbulence changes at centimetre scales or smaller at the point where molecular viscosity converts kinetic energy into heat1, (2) the speed of sound varies at the surface with frequency2,3 and (3) high-frequency waves are strongly attenuated with distance in CO2 (refs. 2,3,4). However, theoretical models were uncertain because of a lack of experimental data at low pressure and the difficulty to characterize turbulence or attenuation in a closed environment.

Sgk1 Is Essential For Meiotic Resumption In Mammalian Oocytes, Edgar Del Llano, Rajan Iyyappan, Daria Aleshkina, Tomas Masek, Michal Dvoran, Zongliang Jiang, Martin Pospisek, Michal Kubelka, Andrej Susor

Faculty Publications

In mammalian females, oocytes are stored in the ovary and meiosis is arrested at the diplotene stage of prophase I. When females reach puberty oocytes are selectively recruited in cycles to grow, overcome the meiotic arrest, complete the first meiotic division and become mature (ready for fertilization). At a molecular level, the master regulator of prophase I arrest and meiotic resumption is the maturation-promoting factor (MPF) complex, formed by the active form of cyclin dependent kinase 1 (CDK1) and Cyclin B1. However, we still do not have complete information regarding the factors implicated in MPF activation. In this study we …

Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be emitted in flavor-changing B meson decays. We report herein a search for an ALP, a, in the reaction B ±→K ± a, a →γ γ using data collected by the BABAR experiment at SLAC. No significant signal is observed, and 90% confidence level upper limits on the ALP coupling to electroweak bosons are derived as a function of ALP mass, improving current …

The Constitutional Right To An Implicit Bias Jury Instruction, Colin Miller Apr 2022

The Constitutional Right To An Implicit Bias Jury Instruction, Colin Miller

Faculty Publications

The Supreme Court has gone to great lengths to prevent jurors from holding defendants’ silence against them. In a trilogy of opinions, the Court concluded that when a defendant refrains from testifying, (1) the prosecutor and judge cannot make adverse comments about that decision; (2) the judge can give a “no adverse inference” instruction even over a defense objection; and (3) the judge must give a “no adverse inference” instruction upon a defense request. Conversely, the Court has never ruled that jurors can impeach their verdict based upon jurors holding a defendant’s silence against him, and lower courts have ruled …

The Miseducation Of Public Citizens, Etienne C. Toussaint

Faculty Publications

The American Bar Association Model Rules of Professional Conduct calls upon lawyers, as public citizens, to embrace a special responsibility for the quality of justice in the legal profession and in society. Yet, some law professors have historically adopted a formalistic and doctrinally neutral approach to law teaching that elides critical perspectives of law, avoids the intersection of law and politics, and tends to overlook the way law can construct the very social injustices that it seeks to contain. The objective, apolitical, and so-called “colorblind” jurisprudential stance in many law classrooms inflicts intellectual violence upon law students who discover a …

Background: Ticks are hematophagous arthropods that transmit various bacterial, viral, and protozoan pathogens of public health significance. The lone star tick (Amblyomma americanum) is an aggressive human-biting tick that transmits bacterial and viral pathogens, and its bites are suspected of eliciting the alpha-gal syndrome, a newly emerged delayed hypersensitivity following consumption of red meat in the United States. While ongoing studies have attempted to investigate the contribution of different tick-inherent factors to the induction of alpha-gal syndrome, an otherwise understudied aspect is the contribution of the tick microbiome and specifically obligate endosymbionts to the establishment of the alpha-gal …
