description: Over the past several decades, amphibians and reptiles have been notably impacted by emerging infectious pathogens. Anuran populations have experienced significant morbidity and mortality events as the result of two pathogens in particular: Batrachochytrium dendrobatidus (Bd), and Frog-Virus 3 (FV-3). Reptiles have also been threatened by infectious pathogens, namely, Ophidiomyces ophidiicola (Oo), which has been attributed to the declines of several snake populations. Here, I present the results of investigations on presence, prevalence and co-occurrence of Bd and FV-3 in anurans, and the occurrence of Oo in snakes in Maryland (at the Smithsonian Environmental Research Center; SERC) and Virginia (at Huntley Meadows Park; HMP). Results from these investigations indicated that Bd is present in both Maryland (10.3%) and Virginia (34.3%). However, FV-3 was not detected in either state. In our investigation of Oo in snakes of Maryland and Virginia, we found an overall infection rate of 55.7%. Our results demonstrate that infectious herpetofaunal pathogens are present at both of our study sites, which emphasizes the need for ongoing disease monitoring at local and regional scales, and the administration of enhanced biosecurity protocols at these sites.

description: In this work we undertake an experimental investigation of plasmas in DC glow discharge, in CO2 /Ar/N2 mixture, for pressures in range 1-6 Torr and currents from 10 to 50 mA, with gas at room and Mars-like temperatures. The vibrational temperatures, the conversion factor and the reduced electric field are measured. The study shows that Martian conditions can effectively pump the asymmetric stretching vibration mode and achieve a stronger non-equilibrium, believed to have a positive influence in dissociation. The results establish experimental evidence of the feasibility of plasma conversion of CO2 from the Martian atmosphere.

description: The available upward-going muon data from the Kamiokande, Baksan, MACRO, IMB, and SuperKamiokande experiments are reviewed and combined. Bounds on the neutrino mass and mixing parameters are derived for oscillations in two and three flavors. These bounds are not in significant conflict with the oscillation solution to the atmospheric neutrino flavor anomaly observed in the sub-GeV and multi-GeV energy range. The combination of all the available atmospheric data tends to favor the nu_mu nu_e channel with respect to the nu_mu nu_tau channel, and to disfavor the threefold maximal mixing scenario.

description: In this work, a modified Holling-Tanner predator-prey model with functional response Holling type II and Allee effect (strong and weak) is considered. It is shown that the dynamics is different to the original Holling-Tanner model, since new equilibrium points can appear in the first quadrant. In more detail, the modified model with strong Allee effect allows for the extinction of both species, while this is not possible in the other two models. In contrast, the modified model with strong Allee effect does not support stable limit cycles, while the other two models do. We also study the changes in the basins of attraction upon varying some of the system parameters. Computer simulations are also shown to illustrate the behaviour of the models.

description: We calculate the critical temperature $T_c$ and the superconducting energy gaps $Δ_n$ of a thin film superconductor system, where $Δ_n$ is the superconducting energy gap of the $n$-th subband. Since the quantization of both the electron energy and phonon spectrum arises due to dimensional confinement in one direction, the effective electron-electron interaction mediated by the quantized confined phonons is different from that mediated by the bulk phonon, leading to the modification of $T_c$ in the thin film system. We investigate the dependence of $T_c$ and $Δ_n$ on the film thickness $d$ with this modified interaction.

description: Recently, topological interfaces between three-dimensional abelian Chern-Simons theories were constructed. In this note we investigate such topological interfaces in the context of the $AdS_3/CFT_2$ correspondence. We show that it is possible to connect the topological interfaces in the bulk Chern-Simons theory to topological interfaces in the dual CFT on the boundary. In addition for $[U(1)]^{2N}$ Chern-Simons theory on $AdS_3$, we show that it is possible to find boundary counter terms which lead to the $N$ conserved currents in the dual two-dimensional CFT.

description: We give a summary about the various contributions which have to be calculated in order to obtain the next-to-leading logarithmic result for the branching ratio $BR(B \to X_s γ)$. Combining all these ingredients, which were obtained by different groups, a complete next-to-leading-logarithmic prediction of the inclusive decay rate was recently presented in the literature. The theoretical uncertainty in the partonic decay rate is now at the 10% level, i.e., less than half of the error in the previous leading-logarithmic result. We also mention the impact of non-perturbative corrections which scale like $1/m_b^2$ and discuss in some more detail the recently discovered corrections which scale like $1/m_c^2$. It turns out that the $1/m_b^2$- and the $1/m_c^2$ terms lead to corrections to the branching ratio $BR(B \to X_s γ)$ well below the 10% level.

description: This thesis has been embargoed for 2 years. It will not be available until July 2023 at the earliest.
description: Current regulation established for disposal of solid waste (e.g., municipal solid waste, and coal combustion residuals) requires disposal facilities to include a composite liner system consisting of a geomembrane overlying a 0.6-m-thick clay liner. Geosynthetic clay liners (GCLs) provide a sustainable alternative to use of in lieu of a conventional clay liner, due to benefits of GCLs having low hydraulic conductivity (< 1 x 10-10 m/s), thin to save air space, and easy to install. GCL consists of one layer of sodium bentonite sandwiched between two layers of geotextile that can be woven or non-woven. These GCLs can be modified through addition of polymerized bentonite, called bentonite polymer composite (BPC), to improve the chemical compatibility of GCLs against aggressive landfill leachates. Due to biodegradation of waste materials, each landfill has an associated temperature gradient that describes an increase in temperature with an increase in depth of the landfill causing leachate within to become hotter with depth of the landfill (Yeşiller, N., and Hanson, J. L. 2003). So far, limited study has investigated the effect of elevated temperatures on the hydraulic conductivity of BPC GCLs Four commercial GCLs were evaluated in this study, including three BPC GCLs and one Na-B GCLs. One BPC GCL consists of bentonite modified with cross-linked polymer and the other two BPC GCLs have liner polymer additives. Hydraulic conductivity tests were conducted with DI water, 20 mM CaCl2 and 50 mM CaCl2 solutions at temperatures of 20 oC, 35 oC, and 60 oC. Swell index tests (ASTM D5890) were conducted to analyze the swelling of BPC compared to Na-B at elevated temperatures. Viscosity tests were conducted to analyze rheology of BPC exposed to DI water, 20 mM CaCl2 and 50 mM CaCl2 solutions at elevated temperatures. Both linear polymers produced an increase in hydraulic conductivity permeated with 50 mM CaCl2 at elevated temperatures, however, BPC GCLs exposed to high temperatures show increase in swell index that can potentially affect hydraulic conductivity results. Additionally, viscosity of permeant solution decreases allowing more polymer to be flushed causing an increase in hydraulic conductivity. The cross link GCL showed little to no change in hydraulic conductivity with change in temperature, however, the elevated temperature test showed a reduction in overall polymer eluted. These observations indicated that the hydrogel swell allowed for less polymer to be eluted during permeation because of the larger size clogging polymer hydrogels between bentonite granules.

description: Paraffin wax has been identified as a promising hybrid rocket fuel. Though attractive from the ballistics point of view, paraffin wax alone is a brittle material. In the present study, the reinforcement of paraffin is pursued through two different approaches: blending paraffin with a thermoplastic polymer and embedding 3D-printed cellular structures inside the pure paraffin. This is named armored grain. The most promising 3D-printed structure is selected and his structural behavior assessed. Mechanical properties of the fuel blends and the armored grains are characterized by compression tests.

description: Background: Returning to employment following moderate to severe traumatic brain injury (msTBI) is critical for a survivor’s well-being, yet currently there are no systematic reviews that comprehensively describe employment outcomes following msTBI. The objective of this study was to systematically synthesize literature on employment outcomes following msTBI. Methods: Original studies published through April 2018 on MEDLINE/PubMed, PsychINFO, and CINAHL were eligible if the objective was to investigate employment outcomes following msTBI; outcome was measured ≥1 year; participants were ≥15; and size was ≥60. Post-injury employment prevalence and return to pre-injury level of work were summarized through meta-analysis. Results: Of 38 eligible studies, post-injury employment prevalence was most often reported (n = 35), followed by job stability (n = 6), and return to pre-injury level of work (n = 4). Overall post-injury employment prevalence was 42.2%; whereas the return-to-previous-work prevalence was 33.0%. Post-injury employment prevalence appeared to increase over time, from 34.9% at 1 year to 42.1% up to 5 years and 49.9% beyond 5 years. Conclusion: Nearly half of individuals with msTBI were employed post-injury, yet only a third returned to pre-injury level of work. Future researchers are recommended to standardize employment outcome measures to enable better comparison of outcomes across studies.

description: In any context in which color superconductivity arises in nature, it is likely to involve pairing between species of quarks with differing chemical potentials. For suitable values of the differences between chemical potentials, Cooper pairs with nonzero total momentum are favored, as was first realized by Larkin, Ovchinnikov, Fulde and Ferrell (LOFF). Condensates of this sort spontaneously break translational and rotational invariance, leading to gaps which vary periodically in a crystalline pattern. Unlike the original LOFF state, these crystalline quark matter condensates include both spin zero and spin one Cooper pairs. We explore the range of parameters for which crystalline color superconductivity arises in the QCD phase diagram. If in some shell within the quark matter core of a neutron star (or within a strange quark star) the quark number densities are such that crystalline color superconductivity arises, rotational vortices may be pinned in this shell, making it a locus for glitch phenomena.

description: We propose nonreciprocal phonon lasing in a coupled cavity system composed of an optomechanical and a spinning resonator. We show that the optical Sagnac effect leads to significant modifications in both the mechanical gain and the power threshold for phonon lasing. More importantly, the phonon lasing in this system is unidirectional, that is the phonon lasing takes place when the coupled system is driven in one direction but not the other. Our work establishes the potential of spinning optomechanical devices for low-power mechanical isolation and unidirectional amplification. This provides a new route, well within the reach of current experimental abilities, to operate cavity optomechanics devices for such a wide range of applications as directional phonon switches, invisible sound sensing, and topological or chiral acoustics.

description: This paper studies the aging behavior of four nano-sized aluminum powders, stored under different conditions in terms of temperature and relative humidity. The nominal particle size of the powders is in the range 40 -200 nm. The particle size distribution of the fresh powders was assessed, as well as the particles morphology and structure, the composition and the reactivity. The aging tests were carried out for periods of time that span from less than 24 hours to 6 months, depending on the storage conditions. The metal content and the low-heating rate reactivity of the aged powders were determined.

description: Accumulating evidence indicates the developing central nervous system (CNS) is a target of air pollution toxicity. Epidemiological reports increasingly demonstrate that exposure to the particulate matter (PM) fraction of air pollution during neurodevelopment is associated with an increased risk of neurodevelopmental disorders (NDDs) such as autism spectrum disorder (ASD). These observations are supported by animal studies demonstrating prenatal exposure to concentrated ambient PM induces neuropathologies characteristic of ASD, including ventriculomegaly and aberrant corpus callosum (CC) myelination. Given the role of the CC and cerebellum in ASD etiology, this study tested whether prenatal exposure to concentrated ambient particles (CAPs) produced pathological features in offspring CC and cerebella consistent with ASD. Analysis of cerebellar myelin density revealed male-specific hypermyelination in CAPs-exposed offspring at postnatal days (PNDs) 11–15 without alteration of cerebellar area. Atomic absorption spectroscopy (AAS) revealed elevated iron (Fe) in the cerebellum of CAPs-exposed female offspring at PNDs 11–15, which connects with previously observed elevated Fe in the female CC. The presence of Fe inclusions, along with aluminum (Al) and silicon (Si) inclusions, were confirmed at nanoscale resolution in the CC along with ultrastructural myelin sheath damage. Furthermore, RNAseq and gene ontology (GO) enrichment analyses revealed cerebellar gene expression was significantly affected by sex and prenatal CAPs exposure with significant enrichment in inflammation and transmembrane transport processes that could underlie observed myelin and metal pathologies. Overall, this study highlights the ability of PM exposure to disrupt myelinogenesis and elucidates novel molecular targets of PM-induced developmental neurotoxicity.

VARI (Vacuum Assisted Resin Infusion) was performed in order to test these sensors. They were integrated inside a vacuum bag with the aim of detecting the position of the resin front advance during the VARI process. These sensors, when integrated in out-of-autoclave processes as flexible electronics for detecting and controlling the resin front advance, may become key elements in producing high quality final composites with a low concentration of voids and dry spots.

description: There are many real-world knowledge based networked systems with multi-type interacting entities that can be regarded as heterogeneous networks including human connections and biological evolutions. One of the main issues in such networks is to predict information diffusion such as shape, growth and size of social events and evolutions in the future. While there exist a variety of works on this topic mainly using a threshold-based approach, they suffer from the local viewpoint on the network and sensitivity to the threshold parameters. In this paper, information diffusion is considered through a latent representation learning of the heterogeneous networks to encode in a deep learning model. To this end, we propose a novel meta-path representation learning approach, Heterogeneous Deep Diffusion(HDD), to exploit meta-paths as main entities in networks. At first, the functional heterogeneous structures of the network are learned by a continuous latent representation through traversing meta-paths with the aim of global end-to-end viewpoint. Then, the well-known deep learning architectures are employed on our generated features to predict diffusion processes in the network. The proposed approach enables us to apply it on different information diffusion tasks such as topic diffusion and cascade prediction. We demonstrate the proposed approach on benchmark network datasets through the well-known evaluation measures. The experimental results show that our approach outperforms the earlier state-of-the-art methods.

description: This paper investigates low-thrust station-keeping strategies for geostationary satellites. On the contratry to traditional low-thrust control methods, which requires ground-station operations in a daily basis, the proposed method maximises the exploitation of natural dynamics and allows for the design of an efficient control within a predefined slot. The dynamical model, based on a spherical coordinate representation, is explored with analytical and numerical techniques to study the phase space. Minimum-time and minimumfuel methods are implemented to design the maneuvers and the two-point boundary value problem is solved via an initial costate evaluation method.
Magnetic Domains and Stripes in the Spin-Fermion Model for Cuprates

description: Monte Carlo simulations applied to the Spin-Fermion model for cuprates show the existence of antiferromagnetic spin domains and charge stripes upon doping. The stripes are partially filled, with a filling of approximately 1/2 hole per site, and they separate spin domains with a $π$ phase shift among them. The stripes observed run either along the x or y axes and they are separated by a large energy barrier. No special boundary conditions or external fields are needed to stabilize these structures at low temperatures. When magnetic incommensurate peaks are observed at momentum $π(1,1-δ)$ and symmetrical points, charge incommensurate peaks appear at $(0,2 δ)$ and symmetrical points, as experimentally observed. The strong charge fluctuations responsible for the formation of the stripes also induce a pseudogap in the density of states.

description: Bacillus anthracis is a dangerous pathogen of humans and many animal species. Its virulence has been mainly attributed to the production of Lethal and Edema toxins as well as the antiphagocytic capsule. Recent data indicate that the nitric oxide (NO) synthase (baNOS) plays an important pathogenic role at the early stage of disease by protecting bacteria from the host reactive species and S-nytrosylating the mitochondrial proteins in macrophages. Another toxin-independent mechanism relevant to late-stage anthrax was shown with non-phagocytic host cells exposed to pathogenic factors secreted by B. anthracis in microaerobic (hypoxic) conditions. In addition to synergistic effect of the pore-forming hemolysin (anthrolysin O) perforating the host cell and the fermentation metabolite (succinic acid) fueling the release of reactive oxygen species from mitochondria, this mechanism involves the activity of NO-derived toxic product(s). In this study we for the first time present evidence that NO produced by baNOS participates in the generation of highly reactive oxidizing species which could be abolished by the NOS inhibitor L-NAME, free thiols, and superoxide dismutase but not catalase. The formation of toxicants is a result of the simultaneous formation of NO and superoxide leading to a labile peroxynitrite and its stable decomposition product, nitrogen dioxide. The toxicity of bacteria could be potentiated in the presence of bovine serum albumin, which serves as a trap of a volatile NO accelerating its reactions. Our data suggest that during infection in the hypoxic environment of pre-mortal host the accumulated NO is expected to have a broad toxic impact on host cell functions.

description: Agricultural production is considered to be one of the main threats to biodiversity. Market-based wildlife-friendly farming (WFF) systems are thought to have great potential to reshape the link between biodiversity and agriculture. In this paper, we explore the potential for WFF rice production in China using choice experiment surveys of consumers and producers. Our results show that there is a significant difference in preferences between urban consumers and rural rice producers. Rice producers pay more attention to the practical concerns around quality (taste), location (ease of working) and prices, while urban consumers pay attention to whether the rice is healthy and free of contamination (e.g. organic or grown with fish). In addition, producers’ price expectations for WFF rice production are not uniform due to different challenges with respect to technology, resource allocation and trust. Preference heterogeniety also exists among urban consumers, some of whom are skeptical of ‘organic labeling’, while others place high levels of trust in rice grown with “biological” indicators such as fish or frogs. Although WFF production systems may not be able to accommodate the full heterogeneity among growers and consumers it can strengthen the incentives to farm more sustainably for the benefit of the economy and the environment if appropriately designed. We suggest the most promising approach is to jointly produce organic rice with fish or another trusted biological indicator to overcome trust issues with existing organic labeling.

description: We disprove the widespread belief that higher order curvature theories of gravity in the metric-affine formalism are generally ghost-free. This is clarified by considering a sub-class of theories constructed only with the Ricci tensor and showing that the non-projectively invariant sector propagates ghost-like degrees of freedom. We also explain how these pathologies can be avoided either by imposing a projective symmetry or additional constraints in the gravity sector. Our results put forward that higher order curvature gravity theories generally remain pathological in the metric-affine (and hybrid) formalisms and highlight the key importance of the projective symmetry and/or additional constraints for their physical viability and, by extension, of general metric-affine theories.

description: We study the quantum speed limit for open quantum systems described by the Lindblad master equation. The obtained inequality shows a trade-off relation between the operation time and the physical quantities such as the energy fluctuation and the entropy production. We further identify a quantity characterizing the speed of the state transformation, which appears only when we consider the open system dynamics in the quantum regime. When the thermal relaxation is dominant compared to the unitary dynamics of the system, we show that this quantity is approximated by the energy fluctuation of the counter-diabatic Hamiltonian which is used as a control field in the shortcuts to adiabaticity protocol. We discuss the physical meaning of the obtained quantum speed limit and try to give better intuition about the speed in open quantum systems.

description: The motion of a single hole in a Mott antiferromagnet is investigated based on the t-J model. An exact expression of the energy spectrum is obtained, in which the irreparable phase string effect [Phys. Rev. Lett. 77, 5102 (1996)] is explicitly present. By identifying the phase string effect with spin backflow, we point out that spin-charge separation must exist in such a system: the doped hole has to decay into a neutral spinon and a spinless holon, together with the phase string. We show that while the spinon remains coherent, the holon motion is deterred by the phase string, resulting in its localization in space. We calculate the electron spectral function which explains the line shape of the spectral function as well as the ``quasiparticle'' spectrum observed in angle-resolved photoemission experiments. Other analytic and numerical approaches are discussed based on the present framework.

description: Peptidyl prolyl cis-trans isomerases (PPIases), which catalyze the interconversion of cisand trans-prolyl peptide bonds, play an important role in protein folding and serve as versatile molecular switches, making these motifs a potentially important drug target; however, their activity is difficult to study. PPIase activity is measured with an enzyme coupled assay using chymotrypsin, which exclusively cleaves the trans-prolyl peptide bonds in the substrate to liberate a chromophore. To increase assay sensitivity, a solventjump is performed by dissolving the substrate in 2,2,2-trifluoroethanol (TFE) with lithium chloride to increase the relative abundance of the cis conformer. We describe a simple solution phase synthesis of the standardized PPIase assay substrate, N-succinyl- Ala-Ala-Pro-Phe-p-nitroanilide, to allow customization of the peptide substrate in-house. Nuclear magnetic resonance (NMR) spectroscopy was used to verify the effects of the LiCl and TFE system, the effects of water contamination on this system, as well as a selection of other salts across the Hofmeister series of anions and cations, on the cis-trans prolyl equilibrium of the substrate.

description: In this work, a modified Holling-Tanner predator-prey model with functional response Holling type II and Allee effect (strong and weak) is considered. It is shown that the dynamics is different to the original Holling-Tanner model, since new equilibrium points can appear in the first quadrant. In more detail, the modified model with strong Allee effect allows for the extinction of both species, while this is not possible in the other two models. In contrast, the modified model with strong Allee effect does not support stable limit cycles, while the other two models do. We also study the changes in the basins of attraction upon varying some of the system parameters. Computer simulations are also shown to illustrate the behaviour of the models.

description: Alzheimer’s disease (AD) is a progressive and currently incurable form of dementia that affects nearly 5.8 million Americans (CDC, 2021). It results in brain atrophy and neuronal death, which with time results in severe memory impairment and loss of ability to function. Activities of daily living (ADLs) and meaningful interactions with others are primarily affected, even in the early stages of the disease. There are numerous variables that exacerbate the progression of Alzheimer’s disease. Some of those variables include isolation and the lack of environmental enrichment. Those burdened with AD are often secluded at home or in a nursing center and there has been extensive research regarding loneliness and isolation in both human and mice models. Contrarily, socialization and environmental enrichment has not been studied substantially. Enriched housing has been shown to have a positive effect on AD progression and could be a promising area of research against Alzheimer’s disease (Griñán-Ferré et al., 2018). This study aims to investigate the effects of rearing conditions on behavioral and neuropathological differences in hTau transgenic Alzheimer’s-type mice. rTg 4510 and 4510 -/- mouse models, which are models of AD were employed in this study. Mice were either reared in Block Party housing or standard cages for a duration of four months, in order to allow for appropriate neurodegeneration to appear in the transgenic subjects. All mice underwent various behavioral testing to assess cognitive deficits. Western blots were used to analyze tau protein and p-Tau concentration. Based on the results of this study, Block Party housing did not ameliorate the pathogenesis of Alzheimer’s Disease. Furthermore, it seems to lead to some negative outcomes for mice housed in this type of paradigm. Nevertheless, these findings have important implications for understanding the behavioral and molecular changes associated with Alzheimer’s disease in mice.

description: We compare results on diffractive W-boson production at the Tevatron with predictions based on the diffractive structure function measured in deep inelastic scattering at HERA assuming (a) conventional factorization or (b) hard factorization combined with a rapidity gap distribution scaled to the total gap probability. We find that conventional factorization fails, while the scaling prediction agrees with the data.

description: We consider an electron coupled to a random distribution of point vortices in the plane (magnetic impurities). We analyze the effect of the magnetic impurities on the density of states of the test particle, when the magnetic impurities have a spatial probability distribution governed by Bose or Fermi statistic at a given temperature. Comparison is made with the Poisson distribution, showing that the zero temperature Fermi distribution corresponds to less disorder. A phase diagram describing isolated impurities versus Landau level oscillations is proposed.

description: Various bioactive polyketides have been found in Aloe barbadensis. However, the polyketide synthases (PKSs), which participate in biosynthesis of polyketides in A. barbadensis remain unknown. In this study, two type III PKSs (AbPKS1 and AbPKS2) were identified from A. barbadensis. AbPKS1 and AbPKS2 were able to utilize malonyl-CoA to yield heptaketides (TW93a and aloesone) and octaketides (SEK4 and SEK4b), respectively. AbPKS1 also exhibited catalytic promiscuity in recognizing CoA thioesters of aromatics to produce unusual polyketides. What Is more, a whole cell biocatalysis system with the capability of producing 26.4 mg/L of SEK4/SEK4b and 2.1 mg/L of aloesone was successfully established.
