description: The simulation of granular particles in a quasi two-dimensional container under the vertical vibration as an experimental accessible model for granular gases is performed. The velocity distribution function obeys an exponential-like function during the vibration and deviates from the exponential function in free-cooling states. It is confirmed that this exponential-like distribution function is produced by Coulomb's friction force. A Langevin equation with Coulomb's friction is proposed to describe the motion of such the system.

description: This paper examines recent contributions to the study of economic growth and attempts to draw inferences relevant to agriculture in the developing regions of South Africa. New growth theory suggests that physical and human resource endowments are wasted if government does not establish the correct economic and political institutions. Indeed, recent empirical findings suggest that rapid growth observed in certain low-income colllltries has more to do with economic policy and institutional change than with public investment in physical and human capital. A brief comparison between institutions in the homelands and those recommended by new growth theory reveals some fundamental problems facing local policy-makers and researchers. These include identifying and implementing strategies that will produce the institutional changes needed to strengthen property rights in land, reduce legal uncertainty in commercial transactions, and ensure that local authorities are exposed to both the economic and political consequences of poor governance.

description: The problem of mass diffusion in layered systems has relevance to applications in different scientific disciplines, e.g., chemistry, material science, soil science, and biomedical engineering. The mathematical challenge in these type of model systems is to match the solutions of the time-dependent diffusion equation in each layer, such that the boundary conditions at the interfaces between them are satisfied. As the number of layers increases, the solutions may become increasingly complicated. Here, we describe an alternative computational approach to multi-layer diffusion problems, which is based on the description of the overdamped Brownian motion of particles via the underdamped Langevin equation. In this approach, the probability distribution function is computed from the statistics of an ensemble of independent single particle trajectories. To allow for simulations of Langevin dynamics in layered systems, the numerical integrator must be supplemented with algorithms for the transitions across the discontinuous interfaces. Algorithms for three common types of discontinuities are presented: (i) A discontinuity in the friction coefficient, (ii) a semi-permeable membrane, and (iii) a step-function chemical potential. The general case of an interface where all three discontinuities are present (Kedem-Katchalsky boundary) is also discussed. We demonstrate the validity and accuracy of the derived algorithms by considering a simple two-layer model system and comparing the Langevin dynamics statistics with analytical solutions and alternative computational results.

description: We present the first full six-dimensional panoramic portrait of the Sagittarius stream, obtained by searching for wide stellar streams in the Gaia DR2 dataset with the STREAMFINDER algorithm. We use the kinematic behavior of the sample to devise a selection of Gaia RR Lyrae, providing excellent distance measurements along the stream. The proper motion data are complemented with radial velocities from public surveys. We find that the global morphological and kinematic properties of the Sagittarius stream are still reasonably well reproduced by the simple Law & Majewski (2010) model (LM10), although the model overestimates the leading arm and trailing arm distances by up to $\sim 15$%. The sample newly reveals the leading arm of the Sagittarius stream as it passes into very crowded regions of the Galactic disk towards the Galactic Anticenter direction. Fortuitously, this part of the stream is almost exactly at the diametrically opposite location from the Galactic Center to the progenitor, which should allow an assessment of the influence of dynamical friction and self-gravity in a way that is nearly independent of the underlying Galactic potential model.

description: The key to the phenomenological success of inflation models with axion and SU(2) gauge fields is the isotropic background of the SU(2) field. Previous studies showed that this isotropic background is an attractor solution during inflation starting from anisotropic (Bianchi Type I) spacetime; however, not all possible initial anisotropic parameter space was explored. In this paper, we explore more generic initial conditions without assuming the initial slow-roll dynamics. We find some initial anisotropic parameter space which does not lead to the isotropic background, but to violation of slow-roll conditions, terminating inflation prematurely. The basin of attraction increases when we introduce another scalar field acting as inflaton and make the axion-SU(2) system a spectator sector. Therefore, the spectator axion-SU(2) model is phenomenologically more attractive.

CHARACTERIZING THE NEUROCHEMICAL, PHYSIOLOGICAL AND BEHAVIORAL EFFECTS OF THE SYNTHETIC CATHINONE α-PYRROLIDINOPENTIOPHENONE (α-PVP)
Creators: name: Nelson, Katharine Hayley
Publisher: name: American University
Year: 2023

description: α-pyrrolidinopentiophenone (α-PVP, Flakka) is a synthetic cathinone that is highly addictive and poses serious risks to the user’s mental and physical health. Despite these dangers, α-PVP remains largely unstudied. The abuse potential of a drug (i.e., its likelihood of self-administration) is dependent upon the balance of the drug’s rewarding and aversive effects and while α-PVP has begun to be studied for these effects, factors that impact them have received little attention. In this context, the goal of these experiments was to further characterize α-PVP by evaluating neurochemical (stereochemistry; Experiment 1), subject (sex; Experiment 2) and experiential (drug history; Experiment 3) factors impacting the affective properties of α-PVP. For Experiments 1A, 2, and 3, the aversive (conditioned taste avoidance (CTA), body temperature, locomotor activity and stereotypies) and rewarding (conditioned place preference (CPP)) effects of α-PVP were investigated. Experiment 1B assessed uptake inhibition of the brain amines, dopamine and norepinephrine. Results: In Experiment 1A, the S-enantiomer of α-PVP mediated the aversive effects of the racemate (in each: CTA, temperature and activity) in male Sprague Dawley (SD) rats at all doses tested. Uptake assessments (Experiment 1B) showed that the R-enantiomer was active, but less potent than the S-enantiomer and racemate. In Experiment 2, male SD rats displayed greater effects of α-PVP than females both in CPP and CTA. Males had a faster onset of temperature effects and had a longer duration of action than females, while females displayed greater locomotor activity than males (although males displayed greater stereotypies than females). In Experiment 3, ethanol pre-exposure attenuated taste avoidance but did not affect reward, which could increase abuse liability. Ethanol pre-exposure increased the locomotor effects of α-PVP (at 3 mg/kg) but had no effect on thermoregulation or stereotypies. The present data indicate that the rewarding and aversive effects of α-PVP are dependent upon its stereochemistry and significantly affected by sex and an ethanol drug history. While these findings lay initial groundwork in characterizing the aversive and rewarding effects of α-PVP, future studies assessing the effects of these properties on intravenous self-administration will be necessary to predict the abuse liability of α-PVP.

The effect of the environment-dependent IMF on the formation and metallicities of stars over the cosmic history

description: Recent observational and theoretical studies indicate that the stellar initial mass function (IMF) varies systematically with the environment (star formation rate - SFR, metallicity). Although the exact dependence of the IMF on those properties is likely to change with improving observational constraints, the reported trend in the shape of the IMF appears robust. We present the first study aiming to evaluate the effect of the IMF variations on the measured cosmic SFR density (SFRD) as a function of metallicity and redshift, $f_{\rm SFR}$(Z,z). We also study the expected number and metallicity of white dwarf, neutron star and black hole progenitors under different IMF assumptions. Applying the empirically driven IMF variations described by the integrated galactic IMF (IGIMF) theory, we correct $f_{\rm SFR}$(Z,z) obtained by Chruslinska & Nelemans (2019) and find lower SFRD at high redshifts as well as a higher fraction of metal-poor stars being formed. In the local Universe, our calculation applying the IGIMF theory suggests more white dwarf and neutron star progenitors in comparison with the universal IMF scenario, while the number of black hole progenitors remains unaffected.

description: We will present a method to decide a priori whether various supersymmetrical scenarios can be distinguished based on sparticle mass data alone. For each model, a scan over all free SUSY breaking parameters reveals the extent of that model's physically allowed region of sparticle-mass-space. Based on the geometrical configuration of these regions in mass-space, it is possible to obtain an estimate of the required accuracy of future sparticle mass measurements to distinguish between the models. We will illustrate this algorithm with an example. This talk is based on work done in collaboration with B.C. Allanach (LAPTH, Annecy) and F. Quevedo (DAMTP, Cambridge).

Evaluating contextual body image, eating, and exercise behaviors in college athletes
Creators: name: McManus, Katherine E.
Publisher: name: American University
Year: 2023

description: The current study assessed the associations between disordered eating, excessive exercise, and contextual body image within a sample of Division I college student-athletes. Sixty-five student-athletes anonymously completed an online survey consisting of a series of eating, exercise, and body image related assessments followed by open-ended questions regarding their motivation to workout and overall student-athlete and college experience. Results indicated that there was no significant association between excessive exercise and disordered eating (r = .19, p = .130; two-tailed), however, there was a significant association between athletic identity and excessive exercise (r = .433, p = .0003). Point biserial correlations and Welch sample t-tests revealed that gender had a significant association with disordered eating (rpb = .324, n = 65, p = .009) however, sport-type did not (rpb = .044, n = 65, p = .729). The current study is consistent with prior research showing that females score higher on scales of disordered eating behavior than males. Furthermore, this study provides evidence to suggest that female athletes may experience differences with their body image, particularly their shape (rpb = .256, n = 65, p = .04), in different contexts (i.e., in daily life context) compared to male athletes. Follow up research should continue to examine the impact of athletic identity, excessive exercise, and disordered eating for all athletes regardless of sport-type and gender.

description: Various thermodynamic quantities and the phase diagram of strongly interacting hot and dense magnetized quark matter are obtained with the $ 2 $-flavour Nambu-Jona-Lasinio model with Polyakov loop considering finite values of the anomalous magnetic moment (AMM) of the quarks. Susceptibilities associated with constituent quark mass and traced Polyakov loop are used to evaluate chiral and deconfinement transition temperatures. It is found that, inclusion of the AMM of the quarks in presence of the background magnetic field results in a substantial decrease in the chiral as well as deconfinement transition temperatures in contrast to an enhancement in the chiral transition temperature in its absence. Using standard techniques of finite temperature field theory, the two point thermo-magnetic mesonic correlation functions in the scalar ($σ$) and neutral pseudoscalar ($π^0$) channels are evaluated to calculate the masses of $σ$ and $ π^0 $ considering the AMM of the quarks.

Year: 1991

description: This study examined the relationship among absorption, anxiety (state and trait), and frontal EMG in a sample of sixty undergraduate students. These relationships were examined during a baseline (relaxation) condition and during an anxiety condition during which an extemporaneous speech was given. It was determined that absorption was inversely related to state anxiety and trait anxiety was directly related to state anxiety measured after the relaxation period. Absorption and/or trait anxiety were not related to state anxiety after the speech anxiety condition. There was no relationship between absorption or trait anxiety and frontal EMG during either condition. In addition, state anxiety and absorption were inversely related at baseline. Implications of these results and directions for future research are presented.

description: We show that fractional flux from Wilson lines can stabilize the moduli of heterotic string compactifications on Calabi-Yau threefolds. We observe that the Wilson lines used in GUT symmetry breaking naturally induce a fractional flux. When combined with a hidden-sector gaugino condensate, this generates a potential for the complex structure moduli, Kahler moduli, and dilaton. This potential has a supersymmetric AdS minimum at moderately weak coupling and large volume. Notably, the necessary ingredients for this construction are often present in realistic models. We explore the type IIA dual phenomenon, which involves Wilson lines in D6-branes wrapping a three-cycle in a Calabi-Yau, and comment on the nature of the fractional instantons which change the Chern-Simons invariant.

Diffusive shock acceleration in $N$ dimensions

description: Collisionless shocks are often studied in two spatial dimensions (2D), to gain insights into the 3D case. We analyze diffusive shock acceleration for an arbitrary number $N\in\mathbb{N}$ of dimensions. For a non-relativistic shock of compression ratio $\mathcal{R}$, the spectral index of the accelerated particles is $s_E=1+N/(\mathcal{R}-1)$; this curiously yields, for any $N$, the familiar $s_E=2$ (i.e., equal energy per logarithmic particle energy bin) for a strong shock in a mono-atomic gas. A precise relation between $s_E$ and the anisotropy along an arbitrary relativistic shock is derived, and is used to obtain an analytic expression for $s_E$ in the case of isotropic angular diffusion, affirming an analogous result in 3D. In particular, this approach yields $s_E = (1+\sqrt{13})/2 \simeq 2.30$ in the ultra-relativistic shock limit for $N=2$, and $s_E(N\to\infty)=2$ for any strong shock. The angular eigenfunctions of the isotropic-diffusion transport equation reduce in 2D to elliptic cosine functions, providing a rigorous solution to the problem; the first function upstream already yields a remarkably accurate approximation. We show how these and additional results can be used to promote the study of shocks in 3D.

description: We have investigated the classical stability of charged black $D3$-branes in type IIB supergravity under small perturbations. For s-wave perturbations it turns out that black $D3$-branes are unstable when they have small charge density. As the charge density increases for given mass density, however, the instability decreases down to zero at a certain finite value of the charge density, and then black $D3$-branes become stable all the way down to the extremal point. It has also been shown that such critical value at which its stability behavior changes agrees very well with the predicted one by the thermodynamic stability behavior of the corresponding black hole system through the Gubser-Mitra conjecture. Unstable mode solutions we found involve non-vanishing fluctuations of the self-dual five-form field strength. Some implications of our results are also discussed.

description: We review the experimental status of the b-quark production at the Fermilab Tevatron. We compare all available measurements to perturbative QCD predictions (NLO and FONLL) and also to the parton-level cross section evaluated with parton-shower Monte Carlo generators. We examine both the single $b$ cross section and the so called b bar{b} correlations. The review shows that the experimental situation is quite complicated because the measurements appear to be inconsistent among themselves. In this situation, there is no solid basis to either claim that perturbative QCD is challenged by these measurements or, in contrast, that long-standing discrepancies between data and theory have been resolved by incrementally improving the measurements and the theoretical prediction.

description: Most childhood cancers occur sporadically and cannot be explained by an inherited mutation or an unhealthy lifestyle. However, risk factors might trigger the oncogenic transformation of cells. Among other regulatory signals, hypermethylation of RAD9A intron 2 is responsible for the increased expression of RAD9A protein, which may play a role in oncogenic transformation. Here, we analyzed the RAD9A intron 2 methylation in primary fibroblasts of 20 patients with primary cancer in childhood and second primary cancer (2N) later in life, 20 matched patients with only one primary cancer in childhood (1N) and 20 matched cancer-free controls (0N), using bisulfite pyrosequencing and deep bisulfite sequencing (DBS). Four 1N patients and one 2N patient displayed elevated mean methylation levels (10 %) of RAD9A. DBS revealed 2 % hypermethylated alleles of RAD9A, indicative for constitutive mosaic epimutations. Bone marrow samples of NHL and AML tumor patients (n=74), EBV (Epstein Barr Virus) lymphoblasts (n=6), tumor cell lines (n=5) and FaDu subclones (n=13) were analyzed to substantiate our findings. We find a broad spectrum of tumor entities with an aberrant methylation of RAD9A. We detected a significant difference in mean methylation of RAD9A for NHL versus AML patients (p ≤0.025). Molecular karyotyping of AML samples during therapy with hypermethylated RAD9A showed an evolving duplication of 1.8 kb on Chr16p13.3 including the PKD1 gene. Radiation, colony formation assays, cell proliferation, PCR and molecular karyotyping SNP-array experiments using generated FaDu subclones suggest that hypermethylation of RAD9A intron 2 is associated with genomic imbalances in regions with tumor-relevant genes and survival of the cells. In conclusion, this is the very first study of RAD9A intron 2 methylation in childhood cancer and Leukemia. RAD9A epimutations may have an impact on leukemia and tumorigenesis and can potentially serve as a biomarker.

description: We study the evolution of the non-equilibrium quantum fields from a highly excited initial state in two approaches: the standard Keldysh-Schwinger diagram technique and the semiclassical expansion. We demonstrate explicitly that these two approaches coincide if the coupling constant $g$ and the Plank constant $\hbar$ are small simultaneously. Also, we discuss loop diagrams of the perturbative approach, which are summed up by the leading order term of the semiclassical expansion. As an example, we consider shear viscosity for the scalar field theory at the leading semiclassical order. We introduce the new technique that unifies both semiclassical and diagrammatic approaches and open the possibility to perform the resummation of the semiclassical contributions.

description: Patterns in the frequency and co-occurrence of anthropogenic pressures associated with suitable breeding habitat for Hen Harriers Circus cyaneus demonstrates the need for specific, focussed management and policy options aimed at mitigating impacts on this threatened population. To describe anthropogenic pressures and threats in the upland breeding range of Hen Harriers and to explore their potential impacts on the declining Hen Harrier population. We used text mining, mixed-effects models, principal component analysis and clustering methods to explore anthropogenic pressures on suitable breeding and foraging habitats for Hen Harriers in Ireland, based on the 2015 national breeding Hen Harrier survey data. Mixed-effects models described a strong influence of agriculture, forestry, predator activity, and recreational activities on survey areas that contained Hen Harrier territories. Cluster analyses described three discrete pressure clusters and showed consistent co-occurrence of independent pressures. Areas of suitable habitat for Hen Harriers in the uplands overlap with areas that experience anthropogenic pressures known to negatively impact on this vulnerable bird species. Combined with clear evidence for the co-occurrence of multiple pressures at a regional scale, this demonstrates a clear need for statutory agencies to consider the potential cumulative impacts of individual pressures when developing conservation strategies for Hen Harriers.

description: Every time an Interactive Storytelling (IS) system gets a player input, it is facing the world-update problem. Classical approaches to this problem consist in mapping that input to known preprogrammed actions, what can severely constrain the free will of the player. When the expected experience has a strong focus on improvisation, like in Role-playing Games (RPGs), this problem is critical. In this paper we present PAYADOR, a different approach that focuses on predicting the outcomes of the actions instead of representing the actions themselves. To implement this approach, we ground a Large Language Model to a minimal representation of the fictional world, obtaining promising results. We make this contribution open-source, so it can be adapted and used for other related research on unleashing the co-creativity power of RPGs.

description: We report $R_cI_c$ light curves of 2 novae in the M31 galaxy which were detected in the four year Nainital Microlensing Survey. One of these novae has been tracked from the initial increase in flux while other has been observed during its descending phase of brightness. The photometry of the first nova during the outburst phase suggests its peak $R_c$ magnitude to be about 17.2 mag with a flux decline rate of 0.11 mag day$^{-1}$ which indicates that it was a fast nova. A month after its outburst, it shows reddening followed by a plateau in $I_c$ flux. The second nova exhibits a bump in $R_c$ and $I_c$, possibly about three weeks after the outburst.

Saudi-Iraqi Relations, 1921-1958
Creators: name: Yaphe, Joshua
Publisher: name: American University
Year: 2023

description: During the period of state formation in the 1920s, Saudi Arabia and Iraq embarked on two different paths with competing visions for managing the border. This generated mistrust on both sides, leading to a gradual process of estrangement that lasted through the 1950s and beyond. Nevertheless, the two countries had a remarkable influence on one another, so that their relations came to have an unforeseen and long-lasting impact on their domestic politics. Ibn Saud made strenuous efforts to preserve the socio-economic ties that united the communities of southern Iraq with the Najd. In turn, those efforts helped encourage a wave of Sunni Arab migrants from Iraq who helped build the Saudi state. Iraqi politicians and clerics attempted to use the issue of Ikhwan raids as a rallying cry for promoting their political agendas. In turn, those attempts contributed to a growing sectarian discourse, undermining the nationalist rhetoric that had flourished during the 1920 Revolution. Iraq and Saudi Arabia have a shared history and their growth as modern nation-states must be understood in that joint context. This study establishes a new narrative and timeline for bilateral relations between the two countries, while examining the word of other Arab and Western scholars in order to excavate the prejudices and biases that have underlined so much of the previous work on this topic. In doing so, it proposes a new way of looking at state formation and boundaries in the Middle East, by showing the ways that regional neighbors left an indelible imprint on each other in this formative period of growth.

description: Most childhood cancers occur sporadically and cannot be explained by an inherited mutation or an unhealthy lifestyle. However, risk factors might trigger the oncogenic transformation of cells. Among other regulatory signals, hypermethylation of RAD9A intron 2 is responsible for the increased expression of RAD9A protein, which may play a role in oncogenic transformation. Here, we analyzed the RAD9A intron 2 methylation in primary fibroblasts of 20 patients with primary cancer in childhood and second primary cancer (2N) later in life, 20 matched patients with only one primary cancer in childhood (1N) and 20 matched cancer-free controls (0N), using bisulfite pyrosequencing and deep bisulfite sequencing (DBS).

Correlation between body pigment reduction and eye reduction in subterranean fish and crustaceans

description: Loss of eye structures and body pigmentation are well documented heritable traits in subterranean organisms. Lamarck and Darwin determined that eye loss in cave organisms must be from disuse and not from natural selection. Since then, evolutionary speleologists have debated whether natural selection or neutral mutation has caused eye loss and de-pigmentation. Here we consider the evolution of eye and pigment reduction in subterranean organisms from a perspective of time rather than cause. While eyes and pigment are advantageous in well-lit environments, eyes maintain advantages in much darker environments than pigment does. This leads to the question of whether pigment reduction occurs before eye reduction in cave organisms. A comprehensive review of eye and pigment phenotypes in 366 subterranean vertebrate and invertebrate species suggests that pigment reduction does occur before eye reduction. In both invertebrate (Fisher’s p = 1.27x10-25) and vertebrate (Fisher’s p = 1.36x10-47) subterranean aquatic organisms body pigment tended to be further reduced relative to eye development.
