Faculty Publications

Bacterial endometritis is among the most common causes of subfertility in mares. It has a major economic impact on the equine breeding industry. The sensitivity of detecting uterine microbes using culture-based methods, irrespective of the sample collection method, double-guarded endometrial swab, endometrial biopsy, or uterine low-volume lavage (LVL), is low. Therefore, equine bacterial endometritis often goes undiagnosed. Sixteen individual mares were enrolled, and an endometrial sample was obtained using each method from all mares. After trimming, quality control and decontamination, 3824 amplicon sequence variants were detected in the dataset. We found using 16S rRNA sequencing that the equine uterus harbors …

Exiting Inflation With A Smooth Scale Factor, Harry Oslislo, Brett Altschul

Faculty Publications

The expectation that the physical expansion of space occurs smoothly may be expressed mathematically as a requirement for continuity in the time derivative of the metric scale factor of the Friedmann–Robertson–Walker cosmology. We explore the consequences of imposing such a smoothness requirement, examining the forms of possible interpolating functions between the end of inflation and subsequent radiation- or matter-dominated eras, using a straightforward geometric model of the interpolating behavior. We quantify the magnitude of the cusp found in a direct transition from the end of slow-roll inflation to the subsequent era, analyze the validity of several smooth interpolator candidates, and …

Design Guidance For Wetland-Road Crossings To Reduce Blanding’S Turtle Mortality Risk, Thomas P. Ballestero, Lauren E. White, Sandra Houghton, David Burdick, Josh Megyesy

Faculty Publications

Road mortality is a leading threat to freshwater turtles, particularly the Blanding’s turtle (Emydoidea blandingii), an endangered species in New Hampshire. Wildlife wetland-crossing structures, such as culverts and/or fences, have proven effective in reducing wildlife road mortality while retaining habitat connectivity. Funding for adequate wetland-crossing creation or restoration is limited, so prioritizing areas of high mortality risk is essential to ensuring that the resources spent are impactful. A research team of professionals from the New Hampshire Department of Environmental Services, New Hampshire Fish and Game, University of New Hampshire, and other organizations formed to create a model capable …

Comparison Of Rheological Methods To Measure Grease Degradation, Alan Gurt, Michael Khonsari

Faculty Publications

In a previous paper, methods that have been used to quantify grease mechanical degradation were compared, finding that crossover stress is a practical method for estimating the cone penetration value of a grease using a small sample. This paper covers techniques that have not generally been applied to modeling grease degradation and indicates their usefulness in characterizing the state of a grease. Three methods are examined, each using a different flow profile: rotation, oscillation, and normal force/extension. It is found that crossover stress is likely still the best choice for estimating cone penetration, and a fast, practical method is introduced …

Organizational Capital And Credit Ratings, Humnath Panta, Arun Narayanasamy, Ayush Panta

Faculty Publications

This study uses pooled OLS to examine the effect of organizational capital on credit ratings using a large sample of US firm data from 1989 to 2017. The main finding reveals that firms with higher organizational capital receive higher credit ratings. This finding is robust to numerous robustness tests, alternative estimation techniques, and attempts to mitigate omitted variable and endogeneity concerns. Further, the positive effect of organizational capital on credit ratings is more prominent when firms are more financially constrained. Overall, our findings reveal the importance of organizational capital in the credit ratings of a firm.

On The Trajectory Of Discrimination: A Meta-Analysis And Forecasting Survey Capturing 44 Years Of Field Experiments On Gender And Hiring Decisions, Helen C.

A preregistered meta-analysis, including 244 effect sizes from 85 field audits and 361,645 individual job applications, tested for gender bias in hiring practices in female-stereotypical and gender-balanced as well as male-stereotypical jobs from 1976 to 2020. A “red team” of independent experts was recruited to increase the rigor and robustness of our meta-analytic approach. A forecasting survey further examined whether laypeople (n = 499 nationally representative adults) and scientists (n = 312) could predict the results. Forecasters correctly anticipated reductions in discrimination against female candidates over time. However, both scientists and laypeople overestimated the continuation of bias against female candidates. …

Relations Among Bitcoin Futures, Bitcoin Spot, Investor Attention, And Sentiment, Arun Narayanasamy, Humnath Panta, Rohit Agarwal

Faculty Publications

This research investigates the function of price discovery between the Bitcoin futures and the spot markets while also analyzing the impact of investor sentiment and attention on these markets. This study utilizes various statistical models to examine the short-term and long-term relations between these variables, including the bivariate Granger causality model, the ARDL and NARDL models, and the Johansen cointegration procedure with a vector error correction mechanism. The results suggest that there is no statistical evidence of price discovery between the Bitcoin spot price and futures, and the term structure of the Bitcoin futures neither enriches nor impairs this lead …

The Superfluous Rules Of Evidence, Jeffrey Bellin

Faculty Publications

There are few American legal codifications as successful as the Federal Rules of Evidence. But this success masks the project’s uncertain beginnings. The drafters of the Federal Rules worried that lawmakers would not adopt the new rules and that judges would not follow them. As a result, they included at least thirty rules of evidence that do not, in fact, alter the admissibility of evidence. Instead, these rules: (1) market the rules project, and (2) guide judges away from anticipated errors in applying the (other) nonsuperfluous rules.

Given the superfluous rules’ covert mission, it should not be surprising that the …

Second Amendment Exceptionalism: Public Expression And Public Carry, Timothy Zick

Faculty Publications

In New York State Rifle & Pistol Ass’n v. Bruen, the Supreme Court recognized a right to carry firearms in public places. The scope of that right will depend on where, why, and how governments regulated public carry during the eighteenth and perhaps nineteenth centuries. The Court claimed that its turn to history for determining the scope of Second Amendment rights “accords with” and “comports with” how the Court has interpreted First Amendment rights. This Article examines and rejects that claim, both in general and specifically as it applies to the public exercise of Second Amendment rights. Although Bruen …

The Independent Agency Myth, Neal Devins, David E. Lewis

Faculty Publications

Republicans and Democrats are fighting the wrong fight over independent agencies. Republicans are wrong to see independent agencies as anathema to hierarchical presidential control of the administrative state. Democrats are likewise wrong to reflexively defend independent agency expertise and influence. Supreme Court Justices also need to break free from this trap; the ongoing struggle over independent agencies should be about facts, not partisan rhetoric.

This Article seeks to reframe the fight over independent agencies. By surveying executive branch and independent agency department heads and supervisors during the Obama (2014) and Trump (2020) administrations, we have assembled unique and expansive data …

A New Rough Ordinal Priority-Based Decision Support System For Purchasing Electric Vehicles, Sadik Kucuksari, Dragan Pamucar, Muhammet Deveci, Nuh Erdogan, Dursun Delen

Faculty Publications

This study proposes a novel multi-criteria decision-making (MCDM) model based on a rough extension of the Ordinal Priority Approach (OPA) to determine the order of importance of users' perspectives on Electric Vehicle (EV) purchases. Unlike conventional methods that rely on predefined ranks for criteria weighting coefficients, the proposed rough OPA method employs an aggregated rough linguistic matrix, enabling a more precise and unbiased calculation of interval values. Moreover, the model addresses inherent uncertainties by incorporating nonlinear aggregation functions, accommodating decision makers' risk attitudes for flexible decision-making. To validate the model's efficacy, a large-scale post-EV test drive survey is conducted, enabling …

Technology Specificity And Equitable Access To Pharmaceuticals, Ana Santos Rutschman

Faculty Publications

Current models of production of pharmaceuticals, particularly those dependent on intellectual property (and adjacent) protections, often contribute to the highly asymmetrical and inequitable distribution of resulting outputs. These problems are especially acute when emerging pathogens cause transnational public health crises in which there is concurrent demand for the same medicines in both lower- and higher-income countries, with populations in the Global South getting very limited timely access, if any, to preventatives and life-saving medicines—even when an outbreak disproportionately affects populations in these very countries.

This essay examines an under-theorized and under-explored way to help correct this historical and persisting deficit …

Impact Of Silicon Ion Irradiation On Aluminum Nitride-Transduced Microelectromechanical Resonators, David D. Lynes, Joshua Young, Eric Lang, Hengky Chandrahalim

Faculty Publications

Microelectromechanical systems (MEMS) resonators use is widespread, from electronic filters and oscillators to physical sensors such as accelerometers and gyroscopes. These devices' ubiquity, small size, and low power consumption make them ideal for use in systems such as CubeSats, micro aerial vehicles, autonomous underwater vehicles, and micro-robots operating in radiation environments. Radiation's interaction with materials manifests as atomic displacement and ionization, resulting in mechanical and electronic property changes, photocurrents, and charge buildup. This study examines silicon (Si) ion irradiation's interaction with piezoelectrically transduced MEMS resonators. Furthermore, the effect of adding a dielectric silicon oxide (SiO₂) thin film is …

Entorhinal Cortical Delta Oscillations Drive Memory Consolidation, Juhee Haam, Suman Gunin, Leslie Wilson, Sydney Fry, Briana Bernstein, Eric Thomson, Hayden Noblet, Jesse Cushman, Jerrel L. Yakel

Faculty Publications

Long-term memories are formed by creating stable memory representations via memory consolidation, which mainly occurs during sleep following the encoding of labile memories in the hippocampus during waking. The entorhinal cortex (EC) has intricate connections with the hippocampus, but its role in memory consolidation is largely unknown. Using cell-type- and input-specific in vivo neural activity recordings, here we show that the temporoammonic pathway neurons in the EC, which directly innervate the output area of the hippocampus, exhibit potent oscillatory activities during anesthesia and sleep. Using in vivo individual and populational neuronal activity recordings, we demonstrate that a subpopulation of the …

Μconadapter: Reinforcement Learning-Based Fast Concurrency Adaptation For Microservices In Cloud, Jianshu Liu, Shungeng Zhang, Qingyang Wang

Faculty Publications

Modern web-facing applications such as e-commerce comprise tens or hundreds of distributed and loosely coupled microservices that promise to facilitate high scalability. While hardware resource scaling approaches [28] have been proposed to address response time fluctuations in critical microservices, little attention has been given to the scaling of soft resources (e.g., threads or database connections), which control hardware resource concurrency. This paper demonstrates that optimal soft resource allocation for critical microservices significantly impacts overall system performance, particularly response time. This suggests the need for fast and intelligent runtime reallocation of soft resources as part of microservices scaling management. We introduce …

Virtual Criminal Law Dualism, Itay Ravid, Hadar Dancig-Rosenberg

Faculty Publications

Since the start of the new millennium, technological and societal changes have initiated a transition from physical to virtual spaces. This farreaching phenomenon has extended to the law and legal institutions, including the criminal law domain. This essay coins the term “virtual criminal law dualism” to describe the dynamic relationship between the virtual and physical spaces in the criminal law sphere. We contend that the transition to virtual spaces has manifested in two distinct aspects. The first relates to formal doctrinal, procedural, and institutional changes that the mainstream criminal law and procedure have undergone due to the emergence of virtual …

140 Characters To Justice? The Promise And Perils Of Using Social Media To Reveal Lay Punishment Perspectives, Itay Ravid, Rotem Dror

Faculty Publications

For centuries, penal theorists have debated two key criminal justice questions: justifying state punishment power and determining proper punishment levels. Moral philosophers offered several theories to address these questions. Over time, calls emerged to move beyond theories and to consider community views on punishment rationales in criminal law and policy design, an approach that gained support alongside meaningful critique. Concurrently, social science advancements enabled empirically deepening understanding of public attitudes about punishment, largely through surveys and experiments.

One domain, however, remained untouched by those calling to assess lay intuitions of justice: social media. Such oversight is puzzling in light of …

Does Grazing Winter Cereal Rye In Iowa, Usa, Make It Profitable?, A. Plastina, J. Acharya, F. M. Marcos, M. R. Parvej, M. A. Licht, A. E. Robertson

Faculty Publications

Unproven economic returns at the farm level are a major barrier to large-scale adoption of cover crops. The objective of this study was to evaluate the short-run private net returns to producers implementing a cereal rye (Secale cereale L.) cover crop preceding the no-till corn (Zea mays L.) phase of a US Midwest corn-soybean (Glycine max [L.] Merr.) rotation in an integrated crop and cow-calf operation. We used experimental agronomic data from six location-years in Iowa to estimate private net returns to cereal rye across alternative scenarios in a partial budget framework. Net returns in the absence of grazing averaged …

Directing The Stereoselectivity Of The Claisen Rearrangement To Form Cyclic Ketones With Full Substitution At The Α-Positions, Fatimat O. Badmus, Raju S. Thombal, Satish Chandra Philkhana, Joshua A. Malone, Christian E. Bailey, Estefania Armendariz-Gonzalez, Edward W. Mureka, Cale M. Locicero, Frank R. Fronczek, Rendy Kartika

Faculty Publications

We report an enantioselective synthesis of cyclic ketones with full substitutions at the α-positions in a highly diastereoselective manner. Our method is achieved by subjecting substrate motifs in 2-allyloxyenones to chiral organomagnesium reagents, which trigger the Claisen rearrangement upon direct 1,2-carbonyl addition. The observed diastereoselectivity of the allyl migration is proposed to originate from the intramolecular chelation of the magnesium alkoxide to the allyloxy moiety.

The boundaries of the chart of nuclides contain exotic isotopes that possess extreme proton-to-neutron asymmetries. Here we report on strong evidence of ⁹N, one of the most exotic proton-rich isotopes where more than one half of its constitute nucleons are unbound. With seven protons and two neutrons, this extremely proton-rich system would represent the first-known example of a ground-state five-proton emitter. The invariant-mass spectrum of its decay products can be fit with two peaks whose energies are consistent with the theoretical predictions of an open-quantum-system approach; however, we cannot rule out the possibility that only a single resonancelike peak …
