Dimensional regularization and supersymmetry

A detailed numerical integration of the Oppenheimer-Volkoff equations for isothermal partially degenerate neutral lepton configurations shows that the mass distribution of the dark halo around the giant elliptical galaxy M87, as revealed by X-ray observations, can be very naturally accounted for, in detail, by an atmosphere of (10–50 eV) neutrinos.     

A front‐capture scheme for the simulation of homogeneous and particle‐laden gravity currents

This paper presents a new finite volume scheme to efficiently simulate gravity currents flowing over complex surfaces. The two‐dimensional shallow‐water equations, with terms to account for friction and particle transport, are solved using a non‐oscillatory technique. By applying a form drag at the front or head of the dense current, the scheme also implicitly captures the correct Froude number condition at the moving front as it intrudes into the less dense ambient fluid. The Froude number of the head region predicted by the numerical simulation is in good agreement with experimental results for a homogeneous current over a horizontal surface if a realistic profile drag coefficient is chosen. This new scheme avoids the development complexities of a general front‐tracking scheme (e.g., handling merging fronts and multiple currents) and the computational cost of solving the full three‐dimensional Euler equations while providing a fast, accurate simulation of gravity currents.

Sequential Power-Dependence Theory

Existing methods for predicting resource divisions in laboratory exchange networks do not take into account the sequential nature of the experimental setting. We extend network exchange theory by considering sequential exchange. We prove that Sequential Power-Dependence Theory—unlike Power-Dependence Theory and most other exchange theories—has a unique point prediction for resource divisions in every network, and we show that these point predictions fare well in comparison to those from established theories.     

Relaxation Limit for Aw-Rascle System

We study the relaxation limit for the Aw-Rascle system of traffic flow. For this we apply the theory of invariant regions and the compensated compactness method to get global existence of Cauchy problem for a particular Aw-Rascle system with source, where the source is the relaxation term, and we show the convergence of this solutions to the equilibrium state.     

Majority-minority influence: identifying argumentative patterns and predicting argument-outcome links

In this paper, the authors investigate the argument activities of majority and minority faction in small group decision-making situations. We begin by identifying patterns of argument that characterize majority and minority communication in 34 discussions and then test several subgroup-outcome and argument-outcome links. Results indicate that winning and losing subgroups argue differently (as do minority and majority subgroups overall) and that consistency in argument is a strong predictor of subgroup success. Both theoretical and practical implications for subgroup influence in group decision making accrue from these findings.     

Heart rate characteristics monitoring for neonatal sepsis

While heart rate variability has been measured in many clinical settings and has offered insights into how HR is controlled, rarely has it offered unique information that has led to changes in patient management. We review our experience in developing continuous HR characteristics monitoring to aid in the early diagnosis of sepsis in premature infants in the neonatal intensive care unit. A predictive algorithm, developed at one center and validated at another, has led to diagnosis and treatment of this subacute and potentially catastrophic illness prior to appearance of symptoms of severe illness.

Actions of Camptothecin Derivatives on Larvae and Adults of the Arboviral Vector Aedes aegypti

Mosquito-borne viruses including dengue, Zika, and Chikungunya viruses, and parasites such as malaria and Onchocerca volvulus endanger health and economic security around the globe, and emerging mosquito-borne pathogens have pandemic potential. However, the rapid spread of insecticide resistance threatens our ability to control mosquito vectors. Larvae of Aedes aegypti were screened with the Medicines for Malaria Venture Pandemic Response Box, an open-source compound library, using INVAPP, an invertebrate automated phenotyping platform suited to high-throughput chemical screening of larval motility. We identified rubitecan (a synthetic derivative of camptothecin) as a hit compound that reduced A. aegypti larval motility. Both rubitecan and camptothecin displayed concentration dependent reduction in larval motility with estimated EC₅₀ of 25.5 ± 5.0 µM and 22.3 ± 5.4 µM, respectively. We extended our investigation to adult mosquitoes and found that camptothecin increased lethality when delivered in a blood meal to A. aegypti adults at 100 µM and 10 µM, and completely blocked egg laying when fed at 100 µM. Camptothecin and its derivatives are inhibitors of topoisomerase I, have known activity against several agricultural pests, and are also approved for the treatment of several cancers. Crucially, they can inhibit Zika virus replication in human cells, so there is potential for dual targeting of both the vector and an important arbovirus that it carries.
