Evaluating The Advantage Of Adaptive Strategies For Quantum Channel Distinguishability, Vishal Katariya, Mark M. Wilde Nov 2021

Evaluating The Advantage Of Adaptive Strategies For Quantum Channel Distinguishability, Vishal Katariya, Mark M. Wilde

Faculty Publications

Recently, the resource theory of asymmetric distinguishability for quantum strategies was introduced by Wang et al. [Phys. Rev. Research 1, 033169 (2019)2643-156410.1103/PhysRevResearch.1.033169.]. The fundamental objects in the resource theory are pairs of quantum strategies, which are generalizations of quantum channels that provide a framework to describe an arbitrary quantum interaction. In the present paper we provide semidefinite program characterizations of the one-shot operational quantities in this resource theory. We then apply these semidefinite programs to study the advantage conferred by adaptive strategies in discrimination and distinguishability distillation of generalized amplitude damping channels. We find that there are significant gaps between …

Real Space Quantum Cluster Formulation For The Typical Medium Theory Of Anderson Localization, Ka Ming Tam, Hanna Terletska, Tom Berlijn, Liviu Chioncel, Juana Moreno Nov 2021

Real Space Quantum Cluster Formulation For The Typical Medium Theory Of Anderson Localization, Ka Ming Tam, Hanna Terletska, Tom Berlijn, Liviu Chioncel, Juana Moreno

Faculty Publications

We develop a real space cluster extension of the typical medium theory (cluster-TMT) to study Anderson localization. By construction, the cluster-TMT approach is formally equivalent to the real space cluster extension of the dynamical mean field theory. Applying the developed method to the 3D Anderson model with a box disorder distribution, we demonstrate that cluster-TMT successfully captures the localization phenomena in all disorder regimes. As a function of the cluster size, our method obtains the correct critical disorder strength for the Anderson localization in 3D, and systematically recovers the re-entrance behavior of the mobility edge. From a general perspective, our …

Sustainable Gardening For School And Home Gardens: Lettuce, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Lettuce is a member of the Asteraceae family, also known as the aster or sunflower family, which includes crops such as globe artichokes and endive, but also garden ornamentals like sunflowers, dahlias, marigolds and zinnias. Cultivated lettuce likely developed from wild lettuce from the Mediterranean area of the Middle East and was first recorded in ancient Egypt around 2500 B.C. in tomb paintings but may have been as early as 4500 B.C. This original lettuce had two main types: one with much thicker stems (like celery) and another that produced seeds used for cooking oil. The stem lettuces (similar to …

Sustainable Gardening For School And Home Gardens: Sweet Pepper, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Peppers are likely native to the Oaxaca region of Mexico, where they are referred to as chiles, with evidence dating back to 5000 B.C. Peppers were also widely produced in Guatemala, and evidence of this crop’s presence in Peru was documented in 1609. They were transported by Spanish and Portuguese explorers and adapted to many different climates. Columbus discovered pungent (hot) peppers in the West Indies and coined the name “pepper.” By the 16th century, peppers were introduced to Europe but were not commercially produced in the southern U.S. until 1925.

Sustainable Gardening For School And Home Gardens: Broccoli And Cauliflower, Johannah Frelier, Denyse Cummins, Carl Motsenbocker Nov 2021

Sustainable Gardening For School And Home Gardens: Broccoli And Cauliflower, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Broccoli and cauliflower are herbaceous plants (meaning they have nonwoody stems) and are widely adapted throughout temperate and subtropical regions of the world. They are closely related members of the Brassicaceae family, also known as the cabbage family, which includes other cool-season cole crops like cabbages, Brussels sprouts, kale, kohlrabi, collards and radishes. Cole crops can tolerate frost, are generally hardy and mature in cool weather. The name broccoli came from the Italian word “brocco,” meaning “shoot,” which refers to sprouting broccoli. The name cauliflower is believed to have been derived from the Italian word “cavolfiore,” meaning “cabbage flower.”

Sustainable Gardening For School And Home Gardens: Tomato, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Tomatoes belong to the Solanaceae family, also known as nightshades, which includes the Irish potato, pepper, tomatillo and eggplant. The first wild tomato plant had bright red, cherry-type fruit and is thought to be native to the Andes Mountains region of Peru and Bolivia. Tomatoes spread to South America and Central America by the natural migration of Indigenous peoples. Confined to the Americas for several thousand years, tomatoes were bred and selected for larger fruit that varied greatly in appearance. The plants were likely bred in Mexico beginning with the Aztecs and Toltecs. There it was traditionally companion planted with …

A Reference Genome For The Nectar-Robbing Black-Throated Flowerpiercer (Diglossa Brunneiventris), A E. Hiller, R T. Brumfield, B C. Faircloth Nov 2021

A Reference Genome For The Nectar-Robbing Black-Throated Flowerpiercer (Diglossa Brunneiventris), A E. Hiller, R T. Brumfield, B C. Faircloth

Faculty Publications

Black-throated Flowerpiercers (Diglossa brunneiventris) are one species representing a phenotypically specialized group of tanagers (Thraupidae) that have hooked bills which allow them to feed by stealing nectar from the base of flowers. Members of the genus are widely distributed in montane regions from Mexico to northern Argentina, and previous studies of Diglossa have focused on their systematics, phylogenetics, and interesting natural history. Despite numerous studies of species within the genus, no genome assembly exists to represent these nectivorous tanagers. We described the assembly of a genome sequence representing a museum-vouchered, wild, female D. brunneiventris collected in Peru. By combining Pacific …

The CALorimetric Electron Telescope CALET is collecting science data on the International Space Station since October 2015 with excellent and continuous performance. Energy is measured with a deep homogeneous calorimeter (1.2 nuclear interaction lengths, 27 radiation lengths) preceded by an imaging pre-shower (3 radiation lengths, 1mm granularity) providing tracking and 10-5 electron/proton discrimination. Two independent sub-systems identify the charge Z of the incident particle from proton to iron and above (Z<40). CALET measures the cosmic-ray electron + positron flux up to 20 TeV, gamma rays up to 10 TeV, and nuclei up to the PeV scale. In this paper, we report the on-orbit performance of the instrument and summarize the main results obtained during the first 5 years of operation, including the electron + positron energy spectrum and the individual spectra of protons, heavier nuclei and iron. Solar modulation and gamma-ray observations are also concisely reported, as well as transient phenomena and the search for gravitational wave counterparts.

Use Of Racial And Ethnic Categories In Medical Testing And Diagnosis: Primum Non Nocere, Jay S. Kaufman, Joanna Merckx, Richard S. Cooper Nov 2021

Use Of Racial And Ethnic Categories In Medical Testing And Diagnosis: Primum Non Nocere, Jay S. Kaufman, Joanna Merckx, Richard S. Cooper

Faculty Publications

BACKGROUND: Use of race and ethnicity is common in medical tests and procedures, even though these categories are defined by sociological, historical, and political processes, and vary considerably in their definitions over time and place. Because all societies organize themselves around these constructs in some way, they are undeniable facets of the human experience, with myriad health consequences. In the biomedical literature, they are also commonly interpreted as representing biological heterogeneity that is relevant for health and disease. CONTENT: We review the use of race and ethnicity in medical practice, especially in the USA, and provide 2 specific examples to …

Coleoptera are visible members of food webs in tea plantations, with high species richness and abundance. Many tea pests, as well as natural enemies, are members of this order, so a knowledge of how groundcovers affect beetles can aid pest management. We collected beetles in a replicated field experiment in the Wuyi Mountains, Fujian Province, China. Tea was intercropped with Paspalum notatum or Chamaecrista rotundifolia, or rows were cleared to bare ground, or in the control they were left unmanaged to allow weeds to grow naturally. Sampling, done by sweep netting and vegetation beating, was conducted monthly, between May 2006 …

Word-Learning Trajectories Influence Long-Term Recall In Children With Developmental Language Disorder And Typical Development, Justin B. Kueser, Laurence B. Leonard, Patricia Deevy, Eileen Haebig, Jeffrey D. Karpicke

Faculty Publications

Introduction: Children with developmental language disorder (DLD) have difficulties learning words. However, the severity of these difficulties can be reduced through word learning procedures that incorporate repeated spaced retrieval (RSR). Previous studies have shown positive outcomes with RSR but we still know very little about how learning unfolds with this procedure. In this study, we focus on the process of learning under RSR. Methods: We analyze the learning data from children with DLD and with typical development (TD) from three recent studies using RSR. We fit growth curves to the trial-by-trial learning data for immediate and spaced retrieval trials and …

Rickettsia Conorii Survival In Thp-1 Macrophages Involves Host Lipid Droplet Alterations And Active Rickettsial Protein Production, Paige E. Allen, Robert C. Noland, Juan J. Martinez

Division of Basic Science Faculty Publications

Rickettsia conorii is a Gram-negative, cytosolic intracellular bacterium that has classically been investigated in terms of endothelial cell infection. However, R. conorii and other human pathogenic Rickettsia species have evolved mechanisms to grow in various cell types, including macrophages, during mammalian infection. During infection of these phagocytes, R. conorii shifts the host cell's overall metabolism towards an anti-inflammatory M2 response, metabolically defined by an increase in host lipid metabolism and oxidative phosphorylation. Lipid metabolism has more recently been identified as a key regulator of host homeostasis through modulation of immune signalling and metabolism. Intracellular pathogens have adapted mechanisms of hijacking …

Hypoglycemia-associated autonomic failure (HAAF) is a maladaptive failure in glucose counterregulation in persons with diabetes (PWD) that is caused by recurrent exposure to hypoglycemia. The adipokine leptin is known to regulate glucose homeostasis, and leptin levels fall following exposure to recurrent hypoglycemia. Yet, little is known regarding how reduced leptin levels influence glucose counterregulation, or if low leptin levels are involved in the development of HAAF. The purpose of this study was to determine the effect of hypoleptinemia on the neuroendocrine responses to hypoglycemia. We utilized two separate experimental paradigms known to induce a hypoleptinemic state: 60% caloric restriction (CR) …

Effective conservation and management necessitate an understanding of the ecological mechanisms that shape species life histories in order to predict how variability in natural and anthropogenic impacts will alter growth rates, recruitment, and survival. Among these mechanisms, the interaction between parturition timing and prey availability frequently influences offspring success, particularly when postnatal care is absent. Here, we assess how parturition timing and nursery conditions, including prey abundance and environmental conditions, influence the growth and potential survival of blacktip sharks (Carcharhinus limbatus) in western Gulf of Mexico (GOM) estuaries over their first year. Catch data from long-term gillnet monitoring allowed for …

Tropical cyclones are the most powerful storms on earth, causing catastrophic damage to human lives and infrastructure. Hurricanes also cause wildlife mortality when they make landfall, but the severity of these effects is difficult to quantify because data collection is either logistically impossible or deprioritized in the wake of human tragedy. On August 27, 2020, Hurricane Laura made landfall in southwestern Louisiana with maximum sustained winds of 241 kph (150 mph), making it one of the most powerful storms to strike the mainland United States. Hurricane Laura passed directly over the core breeding range of the western Gulf Coast population …

Warming from climate change is expected to reduce body size of endotherms, but studies from temperate systems have produced equivocal results. Over four decades, we collected morphometric data on a nonmigratory understory bird community within Amazonian primary rainforest that is experiencing increasingly extreme climate. All 77 species showed lower mean mass since the early 1980s-nearly half with 95% confidence. A third of species concomitantly increased wing length, driving a decrease in mass:wing ratio for 69% of species. Seasonal precipitation patterns were generally better than temperature at explaining morphological variation. Short-term climatic conditions affected all metrics, but time trends in wing …

Floodplain Forests Vegetation Dynamics Driven By Water Deficits Across Scales, Nga Thanh Nguyen Oct 2021

Floodplain Forests Vegetation Dynamics Driven By Water Deficits Across Scales, Nga Thanh Nguyen

LSU Doctoral Dissertations

Restoration of floodplain ecosystems relies on identifying the most crucial hydrologic process which has been altered by human and climate. Flooding is a well-known dominant hydrologic process for floodplain ecosystems, but surprisingly little is known about drought's role in structuring ecosystems. In addition, several issues remained uncertain, such as the nature of drought within floodplains and the sensitivity of floodplain species-specific growth to climate. These gaps of understanding have in common in missing observations of mechanistic pathways of vegetation response to water deficits at multiple scales in time and space.Generally, this research contributed to floodplain management by expanding our understanding …

Heat stress affects oocyte developmental competence and is a major cause of reduced fertility in heat stressed cattle. Negative effects of heat stress on the oocyte have been observed at morphological, biochemical and developmental levels. However, the mechanisms by which heat stress affects the oocyte at the transcriptional and epigenetic levels remain to be further elucidated. Here we aimed to investigate the effect of heat stress on oocyte quality, transcriptomic profiles and DNA methylation of oocytes collected through the transition from spring to summer under Louisiana conditions. Summer season resulted in a lower number of high quality oocytes obtained compared …

The Ross Sea, one of the most productive regions in the Southern Ocean, plays a significant role in deep water formation and carbon cycling. Dissolved organic carbon (DOC) concentrations and chromophoric dissolved organic matter (CDOM) absorption and fluorescence (FDOM) properties were studied in conjunction with biophysical properties during austral summer. Elevated values of both DOC (mean 47.82 ± 5.70 μM) and CDOM (absorption coefficient at 325 nm, acdom325: mean 0.31 ± 0.18 m–1) observed in the upper shelf waters in the southwest (SW), north of the Ross Ice Shelf (RIS), the northwest and along a transect inward of the shelf …

We consider the problem of classifying curves when they are observed only partially on their parameter domains. We propose computational methods for (i) completion of partially observed curves; (ii) assessment of completion variability through a nonparametric multiple imputation procedure; (iii) development of nearest neighbor classifiers compatible with the completion techniques. Our contributions are founded on exploiting the geometric notion of shape of a curve, defined as those aspects of a curve that remain unchanged under translations, rotations and reparameterizations. Explicit incorporation of shape information into the computational methods plays the dual role of limiting the set of all possible completions …
