Α -Logarithmic Negativity, Xin Wang, Mark M. Wilde

Faculty Publications

The logarithmic negativity of a bipartite quantum state is a widely employed entanglement measure in quantum information theory due to the fact that it is easy to compute and serves as an upper bound on distillable entanglement. More recently, the κ entanglement of a bipartite state was shown to be an entanglement measure that is both easily computable and has a precise information-theoretic meaning, being equal to the exact entanglement cost of a bipartite quantum state when the free operations are those that completely preserve the positivity of the partial transpose [Xin Wang and Mark M. Wilde, Phys. Rev. Lett. …

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: …

Caitlin Hebert, Chin Chi Liu, Jacqueline M. Stephens, Leanne M. Redman, Nataki C. Douglas, Jennifer L. Sones

Faculty Publications

© 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 …

Identification Of Pathways Associated With Placental Adaptation To Maternal Nutrient Restriction In Sheep, Ashley K. Edwards, Kathrin A. Dunlap, Thomas E. Spencer, M. Carey Satterfield

Faculty Publications

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 …

Multiple Decrement Life Tables Of Cephus Cinctus Norton (Hymenoptera: Cephidae) Across A Set Of Barley Cultivars: The Importance Of Plant Defense Versus Cannibalism, Buddhi B. Achhami, Robert K.D. Peterson, Jamie D. Sherman, Gadi V.P. Reddy, David K. Weaver

Faculty Publications

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 …

Antixenosis, Antibiosis, And Potential Yield Compensatory Response In Barley Cultivars Exposed To Wheat Stem Sawfly (Hymenoptera: Cephidae) Under Field Conditions, Buddhi B. Achhami, Gadi V.P. Reddy, Jamie D. Sherman, Robert K.D. Peterson, David K. Weaver

Faculty Publications

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 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 …

Division of Basic Science Faculty Publications

Weight loss in response to energy restriction is highly vari-able, and identification of genetic contributors can provide insights into underlying biology. Leveraging 1000 Genomes imputed genotypes, we carried out genome-wide association study (GWAS) analysis in 551 unrelated obese subjects of European ancestry who participated in an intensively supervised weight loss program with replication of promising signals in an independent sample of 1,331 obese subjects who completed the program at a later date. By single nucleotide polymorphism–based and sib-pair analy-sis, we show that that weight loss is a heritable trait, with estimated heritability (h2 = 0.49) within the range reported for …

Phyr: Anrpackage For Phylogenetic Species-Distribution Modelling In Ecological Communities, Daijiang Li, Russell Dinnage, Lucas A. Nell, Matthew R. Helmus, Anthony Ives

Faculty Publications

Model-based approaches are increasingly popular in ecological studies. A good example of this trend is the use of joint species distribution models to ask questions about ecological communities. However, most current applications of model-based methods do not include phylogenies despite the well-known importance of phylogenetic relationships in shaping species distributions and community composition. In part, this is due to a lack of accessible tools allowing ecologists to fit phylogenetic species distribution models easily. To fill this gap, therpackagephyr(pronounced fire) implements a suite of metrics, comparative methods and mixed models that use phylogenies to understand and predict community composition and other …

Making It Free And Easy: Exploring The Effects Of North Carolina College Application Week On College Access, Ashley B. Clayton, Paul D. Umbach

Faculty Publications

This study uses a series of panel models to explore the effect of North Carolina (NC) College Application Week (CAW) and free college applications during that week on the number of applications colleges receive and number of low-income students who matriculate. Our models suggest that NC saw an increase in applications and low-income student enrollments after the implementation of CAW, but these increases largely occurred at private col-leges, seemingly shifting numbers from public universities. We find that the private colleges offering free applications during CAW experienced increases in the total number of both college applications received.

Hydrodynamics, Sediment Transport, And Water Quality Of Two Contrasting Dredge Pits On The Louisiana Shelf, Robert Bales

LSU Master's Theses

Sediment is needed for coastal restoration in Louisiana and is often excavated offshore from both mud-capped and sandy dredge pits. The mined sand from mud-capped pits, like Sandy Point which is west of modern Mississippi Delta of Louisiana, was originally from a paleo river channel and later covered by mud from modern coastal processes. Sandy pits, like Caminada pit in eastern Ship Shoal on Louisiana shelf, generally experience higher energy conditions. To better understand the post-dredging effects on hydrodynamics, sediment transport, and water quality, two tripods were deployed at Caminada and Sandy Point pits in summer 2018 and 2019, respectively, …

Numerical Modeling Of Wave- And Current-Supported Turbidity Currents Over Erodible Bed, Sahar Haddadian

LSU Doctoral Dissertations

The physical processes that route sediments from nearshore to the continental margin provide vital information to the global assessment of the geochemically important matter and the life in the ocean. Therefore, understanding these processes at the fundamental level will help develop accurate models that can be integrated into operational ocean models. Wave- and current-supported turbidity currents (WCSTCs) are one of the mechanisms that deliver sediments to the continental margin. WCSTCs are slow-moving turbidity currents where near-bed turbulence driven by strong surface waves and/or currents, tide- and/or wind-driven, maintain the turbidity current in motion. This study investigates the along-shelf current-supported turbidity …

Conceptual Study Of A Real-Time Hybrid Simulation Framework For Monopile Offshore Wind Turbines Under Wind And Wave Loads, Wei Song, Chao Sun, Yanhui Zuo, Vahid Jahangiri, Yan Lu, Qinghua Han

Faculty Publications

As an attractive renewable energy source, offshore wind plants are becoming increasingly popular for energy production. However, the performance assessment of offshore wind turbine (OWT) structure is a challenging task due to the combined wind-wave loading and difficulties in reproducing such loading conditions in laboratory. Real-time hybrid simulation (RTHS), combining physical testing and numerical simulation in real-time, offers a new venue to study the structural behavior of OWTs. It overcomes the scaling incompatibilities in OWT scaled model testing by replacing the rotor components with an actuation system, driven by an aerodynamic simulation tool running in real-time. In this study, a …

Activity And Regeneration Of Electrodeposited Fe-Ni-Co-Based Electrocatalysts For The Alkaline Oxygen Evolution Reaction, Yujia Zhang, Orhan Kizilkaya, Hubert K. Bilan, Richard Kurtz, Elizabeth J. Podlaha

Faculty Publications

A methodology to recover the oxygen evolution reaction (OER) kinetics of aged, electrodeposited Fe-Ni-Co thin films is presented. The electrodeposits were fabricated galvanostatically onto rotating copper electrodes and contained a small amount of Co. The OER characterized in 1 M KOH was a function of the deposit composition. The Tafel slope and the overpotential at 10 mA/cm2 observed with ohmically corrected linear sweep voltammetry were both a function of the deposit metal ratio, Fe/(Ni + Co), with the lowest values occurring at a ratio of 1.2. An Fe-rich deposit was purposely altered upon aging to degrade the OER kinetics. The …

Modeling Anatomic Changes For Adaptive Radiotherapy In Locally Advanced Lung Cancer Patient Population, James Alexander Kavanaugh

LSU Doctoral Dissertations

Anatomic changes occurring mid-treatment for patients undergoing radiation therapy for locally advanced lung cancer can degrade the quality of the intended treatment plan. These changes include tumor regression, geometric misalignment, and lung density changes (atelectasis and pleural effusion), and are visible on the daily 3D cone beam CT (CBCT). To maintain the intended treatment quality, adaptive radiotherapy (ART) can be employed to modify the treatment plan to account for these anatomic changes. However, the evaluation on when to adapt is currently completed manually by the treating clinicians, resulting in a subjective and inconsistent application. To address these limitations, a series …

Methodologies For Improvement Of Metal Fatigue Life, Ali Haghshenas

LSU Doctoral Dissertations

A methodology is proposed to identify the onset of crack initiation that utilizes the material damping. The damping is measured using the impulse excitation technique (IET). The damping is also used to correlate fatigue life of additively manufactured (AM) specimens to their damping characteristics. Results reveal that the damping value is inversely proportional to the fatigue life of the specimens.

To detect the damage accumulation and crack initiation in metals due to cyclic loading, another methodology based on the measurement of the surface roughness parameters is introduced. Results presented reveal that the evolution of the surface roughness parameters can be …
