description: Mobilization of the Louann Salt created the present structural configuration in the central part of the East Texas Basin and was the major control on hydrocarbon accumulation in the area. Salt-cored anticlines, turtle-structure anticlines, and salt diapirs were produced by flow of salt. Of these, the most prolific oil- and gas-producing structures have been anticlines with deep salt cores. These deep-seated salt domes uplifted thick stratigraphic sections; thus, their crestal anticlines are multiple-zoned productive structures. Turtle-structure anticlines are less important as hydrocarbon traps. Low productivity of turtle-structure anticlines compared with salt-cored anticlines may result from later development of turtle structures and from uplift of a relatively thinner stratigraphic section. Production associated with shallow salt domes has been relatively minor. If a large amount of oil or gas accumulated over the early pillow forms of these diapirs, then much of it may have leaked along faults associated with dome growth or been caused by erosional breaching of reservoirs over the dome crest after uplift. Deeper exploration of each type of structure (salt-cored anticlines, turtle-structure anticlines, and shallow salt domes) may be productive to the oil and gas companies. Shallow salt domes in East Texas have been evaluated as repositories for isolation of nuclear waste. A suitable site must not harbor natural resources that might attract interest and lead to future breaching of the repository. Substantial hydrocarbon accumulations have not been discovered at most of the shallow domes in East Texas. However, these domes have attracted much drilling activity primarily because of highly successful exploration of shallow salt domes in the Gulf Coast Basin.

description: Chikungunya virus (CHIKV) is a pathogenic arthritogenic alphavirus responsible for large-scale human epidemics for which a vaccine was recently approved for use. Mayaro virus (MAYV) is a related emerging alphavirus with epidemic potential with circulation overlap potential with CHIKV. We previously reported the ability of a non-replicating human adenovirus (AdV)-vectored vaccine expressing the MAYV structural polyprotein to protect against disease in mice following challenge with MAYV, CHIKV and UNAV. Herein, we evaluated mouse immunity and protective efficacy for an AdV-CHIKV full structural polyprotein vaccine in combination with heterologous AdV-MAYV prime/boost regimens versus vaccine coadministration. Heterologous prime/boost regimens skewed immunity toward the prime vaccine antigen but allowed for a boost of cross-neutralizing antibodies, while vaccine co-administration elicited robust, balanced responses capable of boosting. All immunization strategies protected against disease from homologous virus infection, but reciprocal protective immunity differences were revealed upon challenge with heterologous viruses. In vivo passive transfer experiments reproduced the inequity in reciprocal cross-protection after heterologous MAYV challenge. We detected in vitro antibody-dependent enhancement of MAYV replication, suggesting a potential mechanism for the lack of cross-protection. Our findings provide important insights into rational alphavirus vaccine design that may have important implications for the evolving alphavirus vaccine landscape.
Chiral Lagrangian and chiral quark model from confinement in QCD

description: The effective chiral Lagrangian in both nonlocal form $L_{ECCL}$ and standard local form $L_{ECL}$ are derived in QCD using the confining kernel, obtained in the vacuum correlator formalism. As a result all coefficients of $L_{ECL}$ can be computed via $q\bar q$ Green's functions. In the $p^2$ order of $L_{ECL}$ one obtains GOR relations and quark decay constants $f_a$ are calculated $a=1,...8$, while in the $p^4$ order the coefficients $L_1, L_2, L_3,L_4, L_5, L_6$ are obtained in good agreement with the values given by data. The chiral quark model is shown to be a simple consequence of $L_{ECCL}$ with defined coefficients. It is demonstrated that $L_{ECCL}$ gives an extension of the limiting low-energy Lagrangian $L_{ECL}$ to arbitrary momenta.

Polynomial Bell inequalities

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: It is a recent realization that many of the concepts and tools of causal discovery in machine learning are highly relevant to problems in quantum information, in particular quantum nonlocality. The crucial ingredient in the connection between both fields is the tool of Bayesian networks, a graphical model used to reason about probabilistic causation. Indeed, Bell's theorem concerns a particular kind of a Bayesian network and Bell inequalities are a special case of linear constraints following from such models. It is thus natural to look for generalized Bell scenarios involving more complex Bayesian networks. The problem, however, relies on the fact that such generalized scenarios are characterized by polynomial Bell inequalities and no current method is available to derive them beyond very simple cases. In this work, we make a significant step in that direction, providing a general and practical method for the derivation of polynomial Bell inequalities in a wide class of scenarios, applying it to a few cases of interest. We also show how our construction naturally gives rise to a notion of non-signalling in generalized networks.

Search for W' to tb in proton-proton collisions at sqrt(s) = 8 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search is performed for the production of a massive W' boson decaying to a top and a bottom quark. The data analysed correspond to an integrated luminosity of 19.7 inverse femtobarns collected with the CMS detector at the LHC in proton-proton collisions at sqrt(s) = 8 TeV. The hadronic decay products of the top quark with high Lorentz boost from the W' boson decay are detected as a single top flavoured jet. The use of jet substructure algorithms allows the top quark jet to be distinguished from standard model QCD background. Limits on the production cross section of a right-handed W' boson are obtained, together with constraints on the left-handed and right-handed couplings of the W' boson to quarks. The production of a right-handed W' boson with a mass below 2.02 TeV decaying to a hadronic final state is excluded at 95% confidence level. This mass limit increases to 2.15 TeV when both hadronic and leptonic decays are considered, and is the most stringent lower mass limit to date in the tb decay mode.

The Super-Natural Supersymmetry and Its Classic Example: M-Theory Inspired NMSSM

description: We briefly review the super-natural supersymmetry (SUSY), which provides a most promising solution to the SUSY electroweak fine-tuning problem. In particular, we address its subtle issues as well. Unlike the Minimal Supersymmetric Standard model (MSSM), the Next to MSSM (NMSSM) can be scale invariant and has no mass parameter in its Lagrangian before SUSY and gauge symmetry breakings. Therefore, the NMSSM is a perfect framework for super-natural SUSY. To give the SUSY breaking soft mass to the singlet, we consider the moduli and dilaton dominant SUSY breaking scenarios in M-theory on $S^1/Z_2$. In these scenarios, SUSY is broken by one and only one $F$-term of moduli or dilaton, and the SUSY breaking soft terms can be determined via the Kähler potential and superpotential from Calabi-Yau compactification of M-theory on $S^1/Z_2$. Thus, as predicted by super-natural SUSY, the SUSY electroweak fine-tuning measure is of unity order. In the moduli dominant SUSY breaking scenario, the right-handed sleptons are relatively light around 1 TeV, stau can be even as light as 580 GeV and degenerate with the lightest neutralino, chargino masses are larger than 1 TeV, the light stop masses are around 2 TeV or larger, the first two-generation squark masses are about 3 TeV or larger, and gluinos are heavier than squarks. In the dilaton dominant SUSY breaking scenario, the qualitative picture remain the same but we have heavier spectra as compared to moduli dominant SUSY breaking scenario. In addition to it, we have Higgs $H_{2}/A_{1}$-resonance solutions for dark matter (DM). In both scenarios, the minimal value of DM relic density is about 0.2. To obtain the observed DM relic density, we can consider the dilution effect from supercritical string cosmology or introduce the axino as the lightest supersymmetric particle.

description: The notion of person-environment fit implies that personal and contextual factors interact in influencing important life outcomes. Using data from 8,458 employed individuals, we examined the combined effects of individuals' actual personality traits and expert-rated personality job demands on earnings. Results using response surface analysis indicated that the fit between individuals’ actual personality and job-demanded personality is a predictor of income. Conclusions of this combined analysis were partly opposite to conclusions reached using conventional regression methods. Individuals can earn additional income up to multiple monthly salaries per year if they hold a job that fits their personality. Thus, at least for some traits, economic success does not only depend on having a "successful personality" but partly on finding the best niche for one's personality. We discuss the findings with regard to labor market policies and individual job selection strategies.

description: Immunotherapy with checkpoint inhibitors including atezolizumab,
pembrolizumab and nivolumab has become an essential pillar in the
management of muscle invasive and metastatic urothelial carcinoma. The field
has evolved quickly in the past few years and several early beliefs have recently
been upended. One such belief relates to the predictive value of PD-L1
expression based on immunohistochemistry. Nevertheless, requirements for
PD-L1 expression from regulatory bodies still restrict the use of checkpoint
inhibitors in urothelial carcinoma. This article provides a critical review of the
available data from the registration trials on which the current regulations have
been based with the conclusion that a review of the current approval status
incorporating PD-1 expression is warranted.
What motivates students? Exploring the factors that influence intrinsic motivation in nursing students when completing academic tasks
Creators: name: Saturne, Stephanie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Background: Many undergraduate nursing students have a clear reason for why they chose to enter the nursing field. However, retention and attrition of nursing students is a current problem throughout nursing schools in the United States. Research focused on factors influencing intrinsic vs. extrinsic motivation has shown significant differences in student learning outcomes and academic success. Students who are intrinsically motivated tend to have more interest in the educational material, receive better grades and learn concepts in more depth.
Aim: The aim for this study is to further explore factors that have been identified as influencing intrinsic motivation in undergraduate nursing students.
Methods: A descriptive study with 85 undergraduate nursing students who were recruited to participate by completing an online questionnaire consisting of stem-completion sentences, a revised version of the Intrinsic Motivation and Interest in Course Material measure and a rank order task.
Results: Undergraduate nursing students provided many variables that contributed to their motivation to complete academic tasks. Some had already been identified in previous literature, such as, grades, studying for understanding, and in order to provide optimal care in future nursing practice.  Responses about what did not motivate the participants to study were, most frequently, busy work, or unnecessary assignments, unapproachable professors and competition among peers. When asked to rank in order certain variables that influenced their motivation, meaningfulness was the most frequent factor selected by participants. Followed by, curiosity, consequence, reward and feedback, respectively.
Conclusion:  Intrinsic motivation is very important for undergraduate nursing students when completing academic tasks. In order to encourage learning in undergraduate nursing students, academic tasks must be perceived as meaningful, curiosity for the material needs to be developed, implementing consequences may be necessary, receiving rewards and feedback from educators are important, as well.

description: The quasi-parallel photon-photon scattering by combining two-color laser fields is an approach to produce resonant states of low-mass fields in laboratory. In this system resonances can be probed via the four-wave mixing process in the vacuum. A search for scalar and pseudoscalar fields was performed by combining 9.3 $μ$J/0.9 ps Ti-Sapphire laser and 100 $μ$J/9 ns Nd:YAG laser. No significant signal of four-wave mixing was observed. We provide the upper limits on the coupling-mass relation for scalar and pseudoscalar fields, respectively, at a 95\% confidence level in the mass region below 0.15~eV.

The Relationship Between Physical Activity Levels and Health Anxiety

description: The majority of Americans do not meet the current physical activity guidelines that were outlined by the U.S. Department of Health and Human Services in 2008. Previous research on panic disorder and psychological constructs such as anxiety sensitivity and body vigilance indicate that individuals who experience health anxiety may be one group of people less likely to participate in physical activity, putting them at risk for a number of health issues. However, no research to date has specifically analyzed the relationship between health anxiety and physical activity levels. The present study investigated the relationship between health anxiety, psychological constructs involved in health anxiety, and physical activity. 438 undergraduate students at the University of North Carolina at Chapel Hill completed an online survey through Qualtrics software in exchange for course credit. Anxiety sensitivity (ASI-3) and depression, anxiety, and stress (DASS-21) were both negatively correlated with all levels of physical activity (aerobic physical activity, resistance training, and gym use). Additionally, experiential avoidance (AAQ-II) was negatively correlated with gym use. Body vigilance (BVS) was not correlated with any measure of physical activity. Health anxiety (SHAI) and anxiety sensitivity (cognitive concerns subscale of ASI-3) emerged as unique predictors of decreased levels of aerobic physical activity. General distress (depression subscale of DASS-21) was a unique predictor of decreased levels of resistance training. Anxiety sensitivity (physical concerns subscale of ASI-3) was a unique predictor of decreased gym use. This research adds clarity to the relationship between psychological disorders/constructs and physical activity.

description: The Bureau of Economic Geology has been conducting regional studies of the Frio Formation along the Texas Gulf Coast to evaluate potential geothermal energy from deep, geopressured sandstone reservoirs (Bebout, Dorfman, and Agagu, 1975; Bebout, Agagu, and Dorfman, 1975). The procedures used in this evaluation were reviewed at the Second Geopressured Geothermal Energy Conference held at The University of Texas at Austin and sponsored by the United States Energy Research and Development Administration. The index map (fig. 1) and cross sections (figs. 2-7) included in this circular were prepared for that meeting and were included in the Proceedings (Bebout, 1976). Published regional cross sections (Corpus Christi Geological Society Study Group, 1954-55, 1964; Deussen and Owen, 1939; Houston Geological Society Study Group, 1954, 1972; and South Texas Geological Society, 1951), unpublished cross sections provided by several major oil companies, and extensive micropaleontological and electrical-log files at the Bureau of Economic Geology served as basic data. These sections are meant to show gross regional distribution of sand and shale facies both laterally and vertically throughout the entire Tertiary section along the Texas Gulf Coast. Closely spaced wells were used for detailed correlation, but for clarity many have been omitted for these cross sections (fig. 1 and table 1). Growth faults tend to obscure regional trends and have been omitted. The top of the geopressure zone is indicated by an arrow. At least eight sand-shale wedges are easily recognized on regional electrical-log cross sections (figs. 2-7). Hardin (1961) illustrated the major wedges as the Midway/Wilcox, Reklaw/Queen City, Weches/Sparta, Cook Mountain/Yegua, Jackson, Vicksburg, Frio, and Anahuac/Fleming. The Pliocene and Pleistocene comprise additional cycles but are undifferentiated in this study. These cycles reflect changes in the ancient shoreline resulting from variations in sediment supply, rate of subsidence, and position of sea level. In general, in the updip end of the wedge the main sand depocenter is in the lower part of the section and downdip it is progressively higher in the section; this is a progradational cycle. In order to emphasize these wedges, the boundary between the facies-related sand-shale couplet is defined by a dashed line on the cross sections. Time lines within the couplet are expected to cross the dashed line as the deltaic or barrier sands prograde basinward over the prodelta or shelf shales.

description: The energy deposition spectra of $^{37}$Ar and $^{71}$Ge in a miniature proportional counter are measured and compared in detail to the model response simulated with Geant4. A certain modification of the Geant4 code, making it possible to trace the deexcitation of atomic shells properly, is suggested. Modified Geant4 is able to reproduce a response of particle detectors in detail in the keV energy range. This feature is very important for the laboratory experiments that search for massive sterile neutrinos as well as for dark matter searches that employ direct detection of recoil nuclei. This work demonstrates the reliability of Geant4 simulation at low energies.

"Unnatural Mother": Race, Gender, and Infanticide in the Nineteenth Century
Creators: name: Pearson, Tyra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: My research focuses on North Carolina’s nineteenth century infanticide cases and uses
them to shed light on bigger issues regarding race, gender, slavery, patriarchy, and law. By focusing on these different aspects, my work builds on previous studies of infanticide. One of the earliest works on this subject was Peter Hoffer and N.E. Hull’s study of infanticide in New England in the years between 1558 and 1803. They quantitatively analyzed data in order to understand the dynamics that caused women to murder their own children. In searching for those influences, Hoffer and Hull wanted to understand why courts began to acquit more women in the eighteenth century as compared to the sixteenth and seventeenth century. They used the law to explain those dire questions and did not give much weight to the women’s circumstances that could have influenced their decision to kill their children. However, Hoffer and Hull did find that women were generally acquitted in the eighteenth century. I show that this pattern continued in the nineteenth century and was not a crime that was unique to New England; instead infanticide instances and rare convictions were also seen in many northern and southern states.
Teacher Strategies for Creating Opportunities for Flow Experiences in Student Learning Through Music
Creators: name: Reeves, Abby
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Every day my second grade teacher spent time with the class gathered around a repurposed surfboard, the whole class singing along as she played guitar. For a young student, this was a daily time of leaving the rules of school behind and simply enjoying the moment with my classmates and teacher, getting lost in the music. Singing gave me a sense of being a part of something greater than myself, belonging to a group in a significant way, and feeling pure joy through vocal expression: experiences that Csikszentmihalyi has conceptualized as “flow.” Experiencing this phenomenon in an educational setting made school more fun, accessible, and worthwhile. My love of choral music continued throughout middle and high school, as meeting the challenge of a difficult vocal performance provided me with an unmatched feeling of self-accomplishment, group connection, and high enjoyment.
This study is based on the possibility that if teachers are able to create this type of musical experience in an academic classroom, students may be more likely to become fully engaged in learning and “get lost” in the creation of a meaningful product during school time. How can teachers approach education in a way that captures the essence of a potential-fulfilling, body-consuming, emotionally immersive musical moment? What classroom strategies can teachers use to make such a meaningful phenomenon more likely among their students? This research will begin to answer these questions.

description: We derive and introduce anisotropic effective pair potentials to coarse-grain solutions of semiflexible rings polymers of various lengths. The system has been recently investigated by means of full monomer-resolved computer simulations, revealing a host of unusual features and structure formation, which, however, cannot be captured by a rotationally-averaged effective pair potential between the rings' centers of mass [M. Bernabei et al., Soft Matter 9, 1287 (2013)]. Our new coarse-graining strategy is to picture each ring as a soft, penetrable disc. We demonstrate that for the short- and intermediate-length rings the new model is quite capable of capturing the Physics in a quantitative fashion, whereas for the largest rings, which resemble flexible ones, it fails at high densities. Our work opens the way for the physical justification of general, anisotropic penetrable interaction potentials.

"I Am Not Going Back-lah":  An Econometric Analysis of Post-Study Inclinations Among Malaysian Students In The United States
Creators: name: Hoo, Yi Rong
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The research in this paper investigates the post-study inclinations of Malaysian students currently studying in the United States after they complete their desired level of education in the US by estimating a multinomial logistic regression. As in previous studies, students studying abroad are thought to be a source of brain drain among developing countries. In a survey conducted for this research, students were asked if they are inclined to return to Malaysia immediately, remain in the United States temporarily or remain in the United States permanently. It was found students who are scholars sponsored by scholarships from various institutions in Malaysia including the Malaysian government are more inclined to return to Malaysia immediately suggesting that such scholarship programs are viable policy tools to counter the brain drain phenomenon among Malaysian students studying abroad. Interestingly, it is also found that students who did not attend public national schools in Malaysia are more inclined to remain in the United States thus begging the question if the structure of Malaysia’s schooling system has an influence on Malaysia’s brain drain predicament. This finding though, would merit further research. It is also found that even after controlling for potential endogeneity, students who had internship experience in Malaysia are less inclined to remain in the United States. Lastly, through a series of different hypothetical scenarios, it is identified that students who desire to pursue an education level beyond a bachelor’s degree to be more inclined to remain in the US permanently if granted permanent residence.

description: The Red Cave Formation (Permian, Leonard Series) in the Texas Panhandle consists of cyclic, red-bed clastic and carbonate-evaporite members that reflect deposition in extensive coastal sabkhas. These environments were bounded on the north by a desert wadi plain and on the south by a carbonate inner shelf that bordered the northern Midland Basin. Evaporite members were deposited in carbonate evaporite coastal sabkhas, and clastic members were deposited in mud-rich coastal to continental sabkhas that passed inland to wadi-plain environments. Inner shelf dolomites include slightly fossiliferous, faintly laminated to burrowed mudstone and pellet wackestone. These lithofacies are overlain by and interfinger northward with dolomite and anhydrite deposited in coastal sabkhas. Oolitic or pellet packstone and grainstone with well-developed cross-lamination suggest shallow subtidal to intertidal deposition. Supratidal facies include dolomitic mudstone with algal laminations and some intraclasts. Sabkha sequences are commonly capped with nodular anhydrite; mud-rich sabkha sequences culminate with red to green mudstone and anhydrite. Carbonate and evaporite facies pinch out generally toward the northwest and northeast into wadi-plain red beds. These facies include ripple-drift, cross-laminated siltstone and sandstone, adhesion-rippled siltstone, and red to green mudstone. Desiccation features, intraclasts, root zones, and paleosol horizons cap braided fluvial deposits and attest to subaerial exposure and probable non-marine conditions. Partial modern analogs to Red Cave sabkha depositional elements include coastal mud flats and alluvial fans in the northwestern Gulf of California, tidal flats and the Wooramel ephemeral stream delta in Gladstone Embayment, Shark Bay, Australia, and Trucial Coast sabkhas in the Persian Gulf. Each setting has certain facets that are remarkably similar to interpreted paleoenvironments and lithofacies of the Red Cave Formation.

description: This report describes preliminary results of an ongoing study of the volcanic stratigraphy, caldera activity, and known and potential mineralization of the Chinati Mountains area of Trans-Pecos Texas. Many ore deposits are spatially associated with calderas and other volcanic centers. A genetic relationship between calderas and base and precious metal mineralization has been proposed by some (Albers and Kleinhampl, 1970) and denied by others (McKee, 1976, 1979). Steven and others (1974) have demonstrated that calderas provide an important setting for mineralization in the San Juan volcanic field of Colorado. Mineralization is not found in all calderas but is apparently restricted to calderas that had complex, post-subsidence igneous activity. A comparison of volcanic setting, volcanic history, caldera evolution, and evidence of mineralization in Trans-Pecos to those of the San Juan volcanic field, a major mineral producer, indicates that Trans-Pecos Texas also could be an important mineralized region. The Chinati caldera complex in Trans-Pecos Texas contains at least two calderas that have had considerable postsubsidence activity and that display large areas of hydrothermal alteration and mineralization. Abundant prospects in Trans-Pecos and numerous producing mines immediately south of the Trans-Pecos volcanic field in Mexico are additional evidence that ore-grade deposits could occur in Texas.
Temporal Aspects of the Thermal Grill Illusion of Pain

description: The thermal grill illusion (TGI) is produced when warm and cool temperatures are simultaneously presented resulting in a hot, burning, painful sensation. The TGI suggests a connection between thermal and pain pathways that, once understood, could lead to a better understanding of pain in general and possible ways to modulate it. The aim of this study was to determine if there is a temporal aspect of the illusion that would affect the way it is felt. Twenty-­four subjects participated in this study which revealed that there is no temporal aspect of the thermal grill illusion that affects pain or thermal components of the illusion. These results suggest that studies differing in the temporal component of the illusion may be compared as methodologically equal. Furthermore, temporal differences cannot be the reason for significant differences in experimental results. Future studies should include use of the thermal grill as it shows great promise to a better understanding of the interaction between pain and thermal
pathways.

description: Introduction: Sites associated with gadolinium (Gd) deposition in the brain (e.g.,
the globus pallidus) are known to contain high concentrations of ferric iron. There
is considerable debate over the mechanism of Gd deposition in the brain. The role
of iron transport mechanisms in Gd deposition has not been determined. Thus,
we seek to identify if Gd deposition can be controlled by modifying iron exposure.
Methods: Female Sprague-Dawley rats were given diets with controlled iron
levels at 2–6 ppm, 6 ppt (20 g/kg Fe carbonyl) or 48 ppm for 3 weeks to induce
iron deficiency, overload or normalcy. They were kept on those diets while
receiving a cumulative 10 mmol/kg dose of gadodiamide intravenously over
2 weeks, then left to washout gadodiamide for 3 days or 3 weeks before tissues
were harvested. Gd concentrations in tissues were analyzed by ICP-MS.
Results: There were no significant effect of dietary iron and total Gd
concentrations in the organs, but there was a significant effect of iron status
on Gd distribution in the brain. For the 3-week washout cohort, there was a nonsignificant
trend of increasing total brain deposition and decreasing dietary iron,
and about 4-fold more Gd in the olfactory bulbs of the low iron group compared
to the other groups. Significant brain accumulation was observed in the low iron
group total brain Gd in the 3-week washout group relative to the 3-day washout
group and no accumulation was observed in other tissues. There was a strong
negative correlation between femur Gd concentrations and concentrations in
other organs when stratifying by dietary iron.
Discussion: Gd brain deposition from linear Gd-based contrast agents (GBCAs)
are dependent upon iron status, likely through variable transferrin saturation. This
iron dependence appears to be associated with redistribution of peripheral
deposited Gd (e.g., in the bone) into the brain.
Big and Useful Maps: Land use / land cover classification with high thematic depth

description: Recent rapid increases in the quality, volume and accessibility of Earth Observation data has spawned a plethora of ambitious global and continental land use / land cover mapping initiatives like ESA’s WorldCover and Google’s DynamicWorld. While such projects are revolutionary in both their scale and their spatial and temporal resolution, they often limit their mapping efforts to a handful of abstract land cover classes like forests, urban areas, and cropland. While this makes it much easier to make accurate global maps and large-scale analyses, it begs the question on how useful these maps are to decision makers who have specific questions and may need more detailed categories, such as distinguishing between different vulnerable nature types and tree plantations or intensively grazed pastures. This creates several challenges, however: Firstly, to what extent are commonly used accuracy metrics suitable for classification tasks with several, often highly imbalanced classes, some of which might occur within the same pixel? Secondly, how do you serve these much more complex datasets to users in a way that actually helps them answer their questions? This project investigates several techniques that leverage the use of sets of predicted probabilities to 1) assess and compare model performance, 2) provide reliable map uncertainty, 3) analyse long-term trends.
Clashes on King Street: The Role of State Officials in the 1964 St. Augustine Racial Crisis

description: The first chapter of this thesis analyzes the deteriorating situation in St. Augustine in 1963. In 1963, local blacks held sit-ins for the integration of private businesses. These sit-ins eventually aroused violent backlash from the Klan in surrounding parts of Florida. This chapter focuses on the failures of local leadership that precipitated the 1964 conflict and pinpoints when state actors played a role in the escalating tensions during the summer of 1963. The second chapter details official responses to the crisis in St. Augustine, with an emphasis on those of state actors. This chapter showcases the lengths to which Warren went to solve the crisis in comparison to the actions of Governor Bryant. The third chapter stresses the differing treatment by state and local officials of the Klan and the almost wholly peaceful civil rights demonstrators. Whites accused the SCLC of fabricating tensions and misrepresenting the city to the world. Simultaneously, state and local officials protected the rights of Klansmen despite their attacks on peaceful protestors. This chapter also highlights shared prejudices held by local officials and Governor Bryant that colored their actions during the crisis and impeded efforts to negotiate with the civil rights marchers.
The intricacies of the 1964 St. Augustine racial crisis are as fascinating as they are overlooked, from Warren’s efforts to use an adulterous affair to combat Ku Klux Klan violence to a biracial commission that never met. State officials molded the course of the civil rights conflict in St. Augustine. Governor Bryant issued key executive orders which resulted in furor from demonstrators on both sides. Dan Warren moved from Daytona Beach to St. Augustine for the duration of the summer of 1964 in order to devote his full attention to aiding the civil rights demonstrators and local officials in coming to a solution to the crisis. The extent of Dan Warren’s involvement as a state official was unprecedented and truly aided the integrationists in demonstrating for equal rights.

description: The World Health Organization recommends that all blood donations be screened for transfusion transmissible infections; these data are currently not incorporated into national disease surveillance efforts. We set out to use routinely collected data from blood donors in Blantyre district, Malawi to explore HIV and syphilis prevalence and identify sero-conversions among repeat donors. We conducted a retrospective cohort analysis of blood donation data collected by the Malawi Blood Transfusion Service from 2015 to 2021. All blood donations were routinely screened for HIV and syphilis. We characterized donor demographics as well as screening outcomes, including identifying sero-conversions among repeat donors who previously tested negative on their last donation. A total of 23,280 donations from 5,051 donors were recorded, with a median frequency of donations of 3 (IQR:2–6). Most donors were male (4,294; 85%) and students (3,262; 64.6%). Prevalence of HIV at first donation was 1.0% (52/5,051) and prevalence of syphilis was 1.6% (80/5,051); 52 HIV sero-conversions and 126 syphilis sero-conversions were identified, indicating an incidence rate per 1,000 person-years of 5.9 (95% CI: 4.7, 7.4) and 13.3 (95% CI:11.4, 15.4) respectively. Students had a lower prevalence of HIV and syphilis but higher risk of syphilis seroconversion. While blood donors are generally considered a low-risk population for HIV and syphilis, we were able to identify relatively high rates of undiagnosed HIV and syphilis infections among donors. Routinely collected data from national blood donation services may be used to better understand local HIV and syphilis epidemiology, with the potential to enhance disease surveillance systems. These findings may be used to identify priority prevention areas and populations in Blantyre district that can inform targeted interventions for improved disease prevention, testing and treatment.

description: We show the operation of a Cu/Al_2O_3/Cu/n-Si hot-electron transistor for the straightforward determination of a metal/semiconductor energy barrier height even at temperatures below carrier-freeze out in the semiconductor. The hot-electron spectroscopy measurements return a fairly temperature independent value for the Cu/n-Si barrier of 0.66 $\pm$ 0.04 eV at temperatures below 180 K, in substantial accordance with mainstream methods based on complex fittings of either current-voltage (I-V) and capacitance-voltage (C-V) measurements. The Cu/n-Si hot-electron transistors exhibit an OFF current of ~2 * 10^-13 A, an ON/OFF ratio of ~10^5 and an equivalent subtreshold swing of ~96 mV/dec at low temperatures, which are suitable values for potential high frequency devices.
