Ab Initio Leading Order Effective Potentials For Elastic Nucleon-Nucleus Scattering, M. Burrows, R. B. Baker, Ch Elster, S. P. Weppner, K. D. Launey, P. Maris, G. Popa Sep 2020

Ab Initio Leading Order Effective Potentials For Elastic Nucleon-Nucleus Scattering, M. Burrows, R. B. Baker, Ch Elster, S. P. Weppner, K. D. Launey, P. Maris, G. Popa

Faculty Publications

Background: Calculating microscopic effective interactions (optical potentials) for elastic nucleon-nucleus scattering has already led to a large body of work. For leading-order calculations a nucleon-nucleon (NN) interaction and a one-body density of the nucleus were taken as input to rigorous calculations of microscopic full-folding calculations. Purpose: Based on the spectator expansion of the multiple scattering series, we employ a chiral next-to-next-to-leading order (NNLO) nucleon-nucleon interaction on the same footing in the structure as well as in the reaction calculation to obtain an effective potential for nucleon-nucleus elastic scattering, consistent in leading-order, which includes the spin of the struck target nucleon.Methods: …

Robust Localized Zero-Energy Modes From Locally Embedded Pt-Symmetric Defects, Fatemeh Mostafavi, Cem Yuce, Omar S. Maganã-Loaiza, Henning Schomerus, Hamidreza Ramezani Sep 2020

Robust Localized Zero-Energy Modes From Locally Embedded Pt-Symmetric Defects, Fatemeh Mostafavi, Cem Yuce, Omar S. Maganã-Loaiza, Henning Schomerus, Hamidreza Ramezani

Faculty Publications

We demonstrate the creation of robust localized zero-energy states that are induced into topologically trivial systems by the insertion of a PT-symmetric defect with local gain and loss. A pair of robust localized states induced by the defect turns into zero-energy modes when the gain-loss contrast exceeds a threshold, at which the defect states encounter an exceptional point. Our approach can be used to obtain robust lasing or perfectly absorbing modes in any part of the system.

Extensive air showers, originating from ultra-high energy cosmic rays, have been successfully measured through the use of arrays of water-Cherenkov detectors (WCDs). Sophisticated analyses exploiting WCD data have made it possible to demonstrate that shower simulations, based on different hadronic-interaction models, cannot reproduce the observed number of muons at the ground. The accurate knowledge of the WCD response to muons is paramount in establishing the exact level of this discrepancy. In this work, we report on a study of the response of a WCD of the Pierre Auger Observatory to atmospheric muons performed with a hodoscope made of resistive plate …

The gravitational-wave signal GW190521 is consistent with a binary black hole (BBH) merger source at redshift 0.8 with unusually high component masses, 85-14+21 M o˙ and 66-18+17 M o˙, compared to previously reported events, and shows mild evidence for spin-induced orbital precession. The primary falls in the mass gap predicted by (pulsational) pair-instability supernova theory, in the approximate range 65-120 M o˙. The probability that at least one of the black holes in GW190521 is in that range is 99.0%. The final mass of the merger (142-16+28 M o˙) classifies it as an intermediate-mass black hole. Under the assumption of …

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Preeclampsia (PE) is a serious hypertensive disorder of pregnancy characterized by abnormal placental development with an unknown etiology. To better understand which women will develop PE, a number of maternal risk factors have been identified, including obesity. Visceral white adipose tissue (WAT) contains inflammatory mediators that may contribute to PE. To explore this, we utilized the blood pressure high (BPH)/5 mouse model of superimposed PE that spontaneously recapitulates the maternal PE syndrome. We hypothesized that BPH/5 visceralWAT adjacent to the female reproductive tract (reproductiveWAT) is a source of complement factors that …

© 2020 The Authors. Ecography published by John Wiley & Sons Ltd on behalf of Nordic Society Oikos Species have been commonly hypothesized to have high population densities in geographic areas which correspond to either the centre of the species geographic range or climatic niche (abundant–centre hypothesis). However, there is mixed empirical support for this relationship, and little theoretical underpinning. We simulate a species spreading across a set of replicated artificial landscapes to examine the expected level of support for abundant–centre relationships in geographic and niche space. Species niche constraints were modeled as a single axis which was related directly …

Maternal nutrient restriction impairs placental growth and development, but available evidence suggests that adaptive mechanisms exist, in a subset of nutrient restricted (NR) ewes, that support normal fetal growth and do not result in intrauterine growth restriction (IUGR). This study utilized Affymetrix GeneChip Bovine and Ovine Genome 1.0 ST Arrays to identify novel placental genes associated with differential fetal growth rates within NR ewes. Singleton pregnancies were generated by embryo transfer and, beginning on Day 35 of pregnancy, ewes received either a 100% NRC (control-fed group; n = 7) or 50% NRC (NR group; n = 24) diet until necropsy …

Leaf bilateral asymmetry, an important indicator of leaves that tend to be affected by the above-ground architectural structure of plants and their environments (especially light), has been poorly studied. Taylor's power law (TPL) describes a power-law relationship between the mean and variance of a non-negative random variable, and its exponent has been demonstrated to reflect the degree of heterogeneity of the branch spatial arrangement of plants. In this study, we checked whether the mean-variance relationship of the absolute difference in area between the left and right sides of 11396 leaves from 35 species of plants within four families followed TPL. …

Accurately estimating cause-specific mortality for immature insect herbivores is usually difficult. The insects are exposed to abiotic and biotic mortality factors, causing cadavers to simply disappear before cause of mortality can be recorded. Also, insect herbivores are often highly mobile on hosts, making it difficult to follow patterns for individuals through time. In contrast, the wheat stem sawfly, Cephus cinctus Norton, spends its entire egg, larval, and pupal period inside a host stem. Therefore, with periodic sampling stage-specific causes of mortality can be ascertained. Consequently, we examined C. cinctus mortality in eight barley, Hordeum vulgare L., cultivars in two locations …

Wheat stem sawfly, Cephus cinctus Norton, is an economically serious pest of cereals grown in North America. Barley cultivars were previously planted as resistant crops in rotations to manage C. cinctus, but due to increasing levels of injury to this crop, this is no longer a valid management tactic in Montana. Therefore, we aimed to understand antixenosis (behavioral preference), antibiosis (mortality), and potential yield compensation (increased productivity in response to stem injuries) in barley exposed to C. cinctus. We examined these traits in eight barley cultivars. Antixenosis was assessed by counting number of eggs per stem and antibiosis was assessed …

Twenty years in since their introduction, it is now plain that the regularized formulations dubbed as phase-field of the variational theory of brittle fracture of Francfort and Marigo (1998) provide a powerful macroscopic theory to describe and predict the propagation of cracks in linear elastic brittle materials under arbitrary quasistatic loading conditions. Over the past ten years, the ability of the phase-field approach to also possibly describe and predict crack nucleation has been under intense investigation. The first of two objectives of this paper is to establish that the existing phase-field approach to fracture at large — irrespectively of its …

Reduced Order Finite Time Observers And Output Feedback For Time-Varying Nonlinear Systems, Frédéric Mazenc, Saeed Ahmed, Michael Malisoff

Faculty Publications

We provide finite time reduced order observers for a class of nonlinear time-varying continuous-time systems. We use the observers to design globally asymptotically stabilizing output feedback controls. We illustrate our work in tracking dynamics for a nonholonomic system in chained form.

Twenty One Years After The Publication Of The Generalized Faustmann Formula, Sun Joseph Chang Sep 2020

Twenty One Years After The Publication Of The Generalized Faustmann Formula, Sun Joseph Chang

Faculty Publications

In this paper, I discuss developments of the generalized Faustmann formula since its publication in 1998. They included the formula for even-aged plantation management, uneven-aged management and forest valuation. These formula were followed by those for forest property taxation and valuation under taxation, the generalized van Kooten model, and the generalized Reed model as well as the uneven-aged management formula with carbon sequestration. The dynamic, incremental solution for the generalized Faustmann formula was then discussed. Pressler's indicator rate formula turned out to be equally applicable under the generalized Faustmann formula. Further, it enables the incorporation of risk preference to deal …

Social Inequalities In Flooding Inside And Outside Of Floodplains During Hurricane Harvey, Kevin T. Smiley Sep 2020

Social Inequalities In Flooding Inside And Outside Of Floodplains During Hurricane Harvey, Kevin T. Smiley

Faculty Publications

While previous research often finds flood impacts outside of conventional flood risk zones such as FEMA's 100-year floodplain maps, we have less of a sense of the social and demographic composition of the areas outside of floodplains that experience these impacts, even though social inequalities in flood risk and impacts more broadly is well-documented in the United States. Using data on 100-year floodplains, flood impacts, socio-demographic characteristics, and residential parcels, this study focuses on race as a primary marker of socio-spatial inequality to examine flooding inside and outside of floodplains during Hurricane Harvey in Greater Houston. Descriptive findings show that …

Grit, Humor, And Suicidal Behavior: Results From A Comparative Study Of Adults In The United States And United Kingdom, Andrea R. Kaniuka, Nicolas Oakey-Frost, Emma H. Moscardini, Raymond P. Tucker, Susan Rasmussen, Robert J. Cramer Sep 2020

Grit, Humor, And Suicidal Behavior: Results From A Comparative Study Of Adults In The United States And United Kingdom, Andrea R. Kaniuka, Nicolas Oakey-Frost, Emma H. Moscardini, Raymond P. Tucker, Susan Rasmussen, Robert J. Cramer

Faculty Publications

Suicidal thoughts and behaviors (STBs) in both the United States (U.S.) and United Kingdom (U.K.) are on the rise. Identification of individual-level protective factors can better inform prevention and intervention efforts. However, the protective role of humor and grit are not yet fully understood. The current study (1) identified the potential protective associations of humor subscale (affiliative, self-enhancing, self-defeating, and aggressive) and grit on STBs among adults, and (2) explored the moderating role of country (U.S. or U.K.) on the relation between humor and grit with STBs. Participants (N = 832) completed self-report measures administered online: Humor Styles Questionnaire, Grit …
