Gravitating discs around black holes

description: Fluid discs and tori around black holes are discussed within different approaches and with the emphasis on the role of disc gravity. First reviewed are the prospects of investigating the gravitational field of a black hole--disc system by analytical solutions of stationary, axially symmetric Einstein's equations. Then, more detailed considerations are focused to middle and outer parts of extended disc-like configurations where relativistic effects are small and the Newtonian description is adequate. Within general relativity, only a static case has been analysed in detail. Results are often very inspiring, however, simplifying assumptions must be imposed: ad hoc profiles of the disc density are commonly assumed and the effects of frame-dragging and completely lacking. Astrophysical discs (e.g. accretion discs in active galactic nuclei) typically extend far beyond the relativistic domain and are fairly diluted. However, self-gravity is still essential for their structure and evolution, as well as for their radiation emission and the impact on the environment around. For example, a nuclear star cluster in a galactic centre may bear various imprints of mutual star--disc interactions, which can be recognised in observational properties, such as the relation between the central mass and stellar velocity dispersion.

Depression and Collegiate Athletes
Creators: name: Fairbanks, Alexis
Publisher: name: American University
Year: 2023

description: The purpose of this study is to examine differences in depressive symptomatology between collegiate club/varsity athletes, intramural athletes, and non athletes. Depression among collegiate athletes is important to study because researchers report that athletes are less likely than non athletes to seek mental health treatment. The current study utilizes data from the spring 2015 American University National College Health Assessment of 1,096 undergraduate students. Analysis of Variance (ANOVA) was conducted to examine potential differences in depression severity by gender, race, or athletic status and to compare mean stress levels by athletic status. Regression analyses were conducted to examine whether the variables of gender, athletic status, or stress are important predictors of depression. Results suggest that athletic status does not significantly increase or decrease an individual’s risk of depression. However, consistent with previous research, females experience more depressive symptomatology than males (p<.05). Results do not support the hypothesis that athletic participation increases an individual’s risk of experiencing depressive symptoms. The study suggests that athletic involvement is unrelated to an individual’s risk of depression. Future researchers should examine depression risk factor unique to collegiate athletes.
An L'-band survey for circumstellar disks around low-mass stars in the young sigma Orionis cluster

description: We present new K- and L'-band imaging of a representative sample of members of the young 3-5 Myr old sigma Orionis cluster. We identified objects with (K-L') excess by analysing colour-colour diagrams and comparing the observations with empirical main-sequence colours. The derived disk frequency depends on the method used: (54 +/- 15)% if measured directly from the JHKL' colour-colour diagram; or (46 +/-14)% if excesses are computed with respect to predicted photospheric colours (according to the objects spectral types, 2-sigma excess detections). We compare the (K-L') excess with other indicators and show that this is a robust and reliable disk indicator. We also compare the derived disk frequency with similarly aged clusters and discuss possible implications for disk lifetimes. The computed age of the sigma Ori cluster is very important: a cluster age of 3 Myr would support the overall disk lifetime of 6 Myr proposed in the literature, while an age > 4 Myr would point to a slower disk destruction rate.

description: Using the SU(3) flavor symmetry, we construct the chiral Lagrangians for the light and heavy pentaquarks. The correction from the nonzero quark is taken into account perturbatively. We derive the Gell-Mann$-$Okubo type relations for various pentaquark multiplet masses and Coleman-Glashow relations for anti-sextet heavy pentaquark magnetic moments. We study possible decays of pentaquarks into conventional hadrons. We also study the interactions between and within various pentaquark multiplets and derive their coupling constants in the symmetry limit. Possible kinematically allowed pionic decay modes are pointed out.

description: Axion models with generation-dependent Peccei-Quinn charges can lead to flavor-changing neutral currents, thus motivating QCD axion searches at precision flavor experiments. We rigorously derive limits on the most general effective flavor-violating couplings from current measurements and assess their discovery potential. For two-body decays we use available experimental data to derive limits on $q\to q' a$ decay rates for all flavor transitions. Axion contributions to neutral-meson mixing are calculated in a systematic way using chiral perturbation theory and operator product expansion. We also discuss in detail baryonic decays and three-body meson decays, which can lead to the best search strategies for some of the couplings. For instance, a strong limit on the $Λ\to n a$ transition can be derived from the supernova SN 1987A. In the near future, dedicated searches for $q\to q' a$ decays at ongoing experiments could potentially test Peccei-Quinn breaking scales up to $10^{12}$ GeV at NA62 or KOTO, and up to $10^{9}$ GeV at Belle II or BES III.

description: We describe a family of tropical fans related to Grassmannian cluster algebras. These fans are related to the kinematic space of massless scattering processes in a number of ways. For each fan associated to the Grassmannian ${\rm Gr}(k,n)$ there is a notion of a generalised $ϕ^3$ amplitude and an associated set of scattering equations which further generalise the ${\rm Gr}(k,n)$ scattering equations that have been recently introduced. Here we focus mostly on the cases related to finite Grassmannian cluster algebras and we explain how face variables for the cluster polytopes are simply related to the scattering equations. For the Grassmannians ${\rm Gr}(4,n)$ the tropical fans we describe are related to the singularities (or symbol letters) of loop amplitudes in planar $\mathcal{N}=4$ super Yang-Mills theory. We show how each choice of tropical fan leads to a natural class of polylogarithms, generalising the notion of cluster adjacency and we describe how the currently known loop data fit into this classification.

On Non-Primordial Deuterium Production by Accelerated Particles

name: Fields, Brian D.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Deuterium plays a crucial role in cosmology because the primordial D/H abundance, in the context of big bang nucleosynthesis (BBN) theory, yields a precise measure of the cosmic baryon content. Observations of D/H can limit or measure the true primordial abundance because D is thought to be destroyed by stars and thus D/H monotonically decreases after BBN. Recently, however, Mullan & Linsky have pointed out that D arises as a secondary product of neutrons in stellar flares which then capture on protons via n+p \to d + gamma, and that this could dominate over direct D production in flares. Mullan & Linsky note that if this process is sufficiently vigorous in flaring dwarf stars, it could lead to significant non-BBN D production. We have considered the production of D in stellar flares, both directly and by n capture. We find that for reasonable flare spectra, n/d < 10 and (n+d)/6Li < 400, both of which indicate that the n-capture channel does not allow for Galactic D production at a level which will reverse the monotonic decline of D. We also calculate the 2.22 MeV gamma-ray line production associated with n capture, and find that existing COMPTEL limits also rule out significant D production in the Galaxy today. Thus, we find flares in particular, and neutron captures in general, are not an important Galactic source of D. On the other hand, we cannot exclude that flare production might contribute to recent FUSE observations of large variations in the local interstellar D/H abundance; we do, however, offer important constraints on this possibility. Finally, since flare stars should inevitably produce some n-capture events, a search for diffuse 2.22 MeV gamma-rays by INTEGRAL can further constrain (or measure!) Galactic deuterium production via n-capture.

description: Supply chain security threats pose new challenges to security risk modeling techniques for complex ICT systems such as the IoT. With established techniques drawn from attack trees and reliability analysis providing needed points of reference, graph-based analysis can provide a framework for considering the role of suppliers in such systems. We present such a framework here while highlighting the need for a component-centered model. Given resource limitations when applying this model to existing systems, we study various classes of uncertainties in model development, including structural uncertainties and uncertainties in the magnitude of estimated event probabilities. Using case studies, we find that structural uncertainties constitute a greater challenge to model utility and as such should receive particular attention. Best practices in the face of these uncertainties are proposed.

description: Science, Technology, Engineering and Mathematics (STEM) Project-Based Learning (PjBL) is increase effectiveness, create meaningful learning and influence student attitudes in future career pursuit. There are several studies in the literature reporting different aspects of STEM into a PjBL pedagogy. However, the effect of implementing STEM PjBL in terms of improving students’ skills in self-efficacy levels in physics mechanics at high school level has not been demonstrated as expected in the previous literature. This study followed a quasi-experimental research method. Bandura’s social cognitive theory is used to assess and compare the effect of STEM PjBL with conventional teaching method on students’ self-efficacy level in learning physics among over 100 high school students. The result illustrated that STEM PjBL improve students’ self-efficacy to solve physics problem. Also, the study proposes a guideline for future research.

The man trapped in his illness, who has become nothing more than “a place to hang a coat,” imagines trading his bed for an iron lung to relieve his family of having to see or touch him. He is able, finally, to transform out of that bodily iron lung to spirit. And the horse thief uncle, skating across the St. Lawrence River, imagines his body becoming the beloved Morgan he’d had to leave behind. By the end of the poem, the uncle has transformed into his beautiful horse and was never heard from again. What the author does not provide is an answer to how the transformations occur—only a confident voice that they do occur—giving hope that loss can be transformative.

description: Topology concepts have significantly deepened of our understanding in recent years of the electronic properties of one-dimensional (1D) nano structures such as the graphene nanoribbons. Controlling topological electronic properties of GNRs has been demonstrated in both theoretical studies and experimental realization. Most previous works rely on classification theory requiring both time reversal and spatial symmetry of a unit cell in the 1D bulk material that is commensurate to its boundary. To access boundary structures that lead to unit cell with no spatial symmetry and to generalize the theory, we propose here another classification scheme, using chiral symmetry, to arrive at a Z classification that is not only applicable to GNRs with arbitrary terminations, but also to any general 1D chiral structures. This theory, combining with Lieb's theorem, moreover enables access to the electron's spin degree of freedom, allowing for investigation of spin physics.

description: The issue of domain walls in the recently extended Veneziano-Yankielowicz theory is investigated and we show that they have an interesting substructure. We also demonstrate the presence of a noncompact modulus. The associated family of degenerate solutions is physically due to the presence of a valley of vacua in the enlarged space of fields. This is a feature of the extended Veneziano-Yankielowicz theory. Unfortunately the above properties do not match the ones expected for the domain walls of N=1 super Yang-Mills.

description: In the present paper, we investigate the properties of the sound generated by rubbing two objects. It is clear that the sound is generated because of the rubbing between the contacting rough surfaces of the objects. A model is presented to account for the role played by the surface roughness. The results indicate that tonal features of the sound can be generated due to the finiteness of the rubbing surfaces. In addition, the analysis shows that with increasing rubbing speed, more and more high frequency tones can be excited and the frequency band gets broader and broader, a feature which appears to agree with our intuition or experience.

History of Hydrogen Reionization in the Cold Dark Matter Model
Creators: name: Onken, Christopher A.
name: Miralda-Escude, Jordi
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We calculate the reionization history in Cold Dark Matter (CDM) models. The epoch of the end of reionization and the Thomson scattering optical depth to the cosmic microwave background depend on the power spectrum amplitude on small scales and on the ionizing photon emissivity per unit mass in collapsed halos. We calibrate the emissivity to reproduce the measured ionizing background intensity at z=4. Models in which all CDM halos have either a constant emissivity or a constant energy emitted per Hubble time, per unit mass, predict that reionization ends near z~6 and the optical depth is in the range 0.05 < tau_e < 0.09, consistent with WMAP results at the 1 to 2 sigma level. If the optical depth is as high as 0.17 (as suggested by WMAP), halos of velocity dispersion ~ 3-30 km/s at z>15 must have ionizing emissivities per unit mass larger by a factor >~ 50 compared to the more massive halos that produce the ionizing emissivity at z=4. This factor increases to 100 if the CDM power spectrum amplitude is required to agree with the Croft et al. (2002) measurement from the Lyman alpha forest. If tau_e >~ 0.17 were confirmed, a higher ionizing emissivity at z>15 compared to z=4 might arise from an enhanced star formation rate or quasar abundance per unit mass and an increased escape fraction for ionizing photons; the end of reionization could have been delayed to z~6 because of the suppression of gas accretion and star formation in low-mass halos as the medium was reionized.

description: The dinitrides CN2, SiN2, and GeN2 in assumed pyrite-type structures are studied by means of density functional theory using both ultrasoft pseudopotentials and the augmented spherical wave (ASW) method. The former two materials constitute the large-x limit of the broader class of CNx and SiNx compounds, which are well known for their interesting mechanical and electronic properties. For CN2 a large bulk modulus B_0 of 405 GPa was determined . While SiN2 is found to be a wide band gap compound, the calculated gaps of CN2 and GeN2 are considerably smaller. The trends in structural and electronic properties as e.g. bond lengths, band gaps and covalency are well understood in terms of the interplay of different types of bonding.

The objective of this study is to optimize the distribution of active and reactive energy in the supply of sub-distribution or the market. The model proposed in this paper accounts for the effects associated with switching capacitors on distribution and dispatching centers. Using capacitors in the power grid has an effect on bus voltage and consequently the amount of active and reactive energy demand of the consumer. The optimized supply is determined through the solution of a mathematical operation model. In this study, the effect of voltage changes on consumer demand for residential,commercial and industrial power are quantified and embodied in an analytical model, which is then solved using General Algebraic Modeling System (GAMS) software.ware.

description: There is evidence that prebiotics can impart a range of health benefits if consumed on a regular basis. With a growing market for prebiotic-containing foods there is increasing interest in understanding how prebiotics function at the molecular level. Advances in the genomics of lactobacilli and bifidobacteria have enabled modeling of transport and catabolic pathways for prebiotic utilization. The goal of this study was to develop a physiological model of the upper gastrointestinal tract to investigate the metabolic profile of probiotic strain Lactobacillus bulgaricus L14 in present of 0.75% polysaccharides obtained from Plantago major L. leaves. The polysaccharide degradation and utilization from probiotic strain L14 using in vitro model including gastric phase and intestinal phase simulated digestion in humans was developed.

title: The effect of cholinergic loss on the structure and function of the neurovascular unit: implications for cerebral amyloid angiopathy
Creators: name: Nizari, Shereen
Publisher: name: The Open University
Year: 2019

description: Innervation of cerebral blood vessels is important for the regulation of vascular tone and adequate cerebral perfusion. Alzheimer’s disease (AD) is characterised by a loss of cholinergic innervation of the neurovascular unit (NVU). This loss may contribute not only to inefficient cerebrovascular perfusion, but also to the failure of removal of amyloid-β (Aβ), leading to its accumulation as cerebral amyloid angiopathy (CAA). This hypothesis was tested by mimicking loss of cholinergic innervation of the cortex and hippocampus in adult male C57BL/6 mice using the immunospecific toxin mu-p75-saporin. Using quadruple labelling immunohistochemistry and 3D reconstructions of the NVU, loss of perivascular cholinergic innervation was observed at the smooth muscle cells and basement membrane in the cortex and hippocampus, with additional perivascular loss at the astrocyte endfeet in the cortex. Arterial spin labelling fMRI revealed no differences in resting cerebral blood flow between control and saporin-treated mice in either the cortex or hippocampus. However, denervated vessels in the cortex, but not the hippocampus, failed to respond to pharmacological stimulation of endothelial nitric oxide synthase (eNOS). Further studies revealed a decrease in eNOS expression in the cortex, but an increase in eNOS expression and activity in the hippocampus following loss of cholinergic input. No differences were noted between control and saporin-treated mice in the efficiency of removal of Aβ along perivascular basement membranes in either the cortex or hippocampus. Treatment of TetO-APPSweInd mice with saporin resulted in a trend towards higher CAA load. These data suggest that there are innate differences between NVUs of the cortex and the hippocampus and a difference in their functional response to loss of cholinergic input. Loss of cholinergic input at the NVU may contribute to accumulation of Aβ; however, this likely requires additional pathological factors for CAA to develop.

description: Magnetic properties of the novel layered superconductor, Na$_{0.35}$CoO$_{2}$$\cdot$1.3H$_{2}$O have been investigated. From the temperature dependence and field dependence of the magnetization, the superconducting transition temperature, as well as upper- and lower-critical fields have been estimated to be $T_{C}=4.6$ K, $H_{C2}(0)=61.0$ T and $H_{C1}(0)=28.1$ Oe. These values give quite unusual phenomenological parameters, \textit{i.e.}, coherent length, penetration depth and Ginzburg-Landau parameter of $ξ=2.32$ nm, $λ=5.68\times 10^{3}$ Å and $κ\equivλ/ξ=244$, suggesting an unconventional nature of superconductivity. Normal-state magnetic susceptibility shows an upturn below 130 K, which is confirmed to be inherent by high-field magnetization data. The upturn may have relevance to the mechanism of the superconductivity.

description: Even when low-income countries face similar health threats and are under similar pressure to act from a global community of health organizations and donors, notable variation in the aggressiveness of health policies is apparent. Health policy aggressiveness here is defined as how quickly and comprehensively countries have acted to address these problems. Most previous scholarship on political attention to particular diseases has focused on one issue in one country, with limited work considering why policy adoption and implementation differs across policy target groups, across health issues and across nations. In each of the three papers of this dissertation project I explore what has shaped political attention and policy aggressiveness for HIV/AIDS and tuberculosis, with particular attention to how issue-related stigma and framing shape how policy target groups are socially constructed, altering policy aggressiveness across target groups (Chapter I), how these factors influence variation in policy aggressiveness across countries (Chapter II), and how they contribute to differences in policy aggressiveness between health issues in South Africa (Chapter II and Chapter III). I use both qualitative and quantitative methods and combine and build on theories of the policy process, international relations, comparative politics, sociology, social psychology, and public health in my analyses. The findings of these three papers help to address the gaps in what we know about policy aggressiveness while also contributing to the development of more refined theory, of new theoretical propositions for research, and of practical insights to be used by advocates and policy makers working on health issues.

description: Nearly one-third of the sources in the $Fermi$-LAT catalogs lack a lower energy counterpart, hence being referred as unidentified/unassociated gamma-ray sources (UGSs). In order to firmly classify them, dedicated multifrequency follow-up campaigns are necessary. These will permit to unveil their nature and identify the fraction that could belong to the class of active galaxies known as blazars that is the largest population of extragalactic $γ$-ray sources. In $Fermi$-LAT catalogs there are also gamma-ray sources associated with multifrequency blazar-like objects known as Blazars Candidates of Uncertain type (i.e., BCUs) for which follow up spectroscopic campaigns are mandatory to confirm their blazar nature. Thus, in 2013 we started an optical spectroscopic campaign to identify blazar-like objects potential counterparts of UGSs and BCUs. Here we report the spectra of 31 additional targets observed as part of our follow up campaign. Thirteen of them are BCUs for which we acquired spectroscopic observations at Observatorio Astrofísico Guillermo Haro (OAGH) and at Southern Astrophysical Research Observatory (SOAR) telescopes, while the rest has been identified thanks to the archival observations available from the Sloan Digital Sky Survey (SDSS). We confirm the blazar nature of all BCUs: three of them are in blazar of quasar type (BZQs) while the remaining ones can be spectroscopically classified as BL Lac objects (BZBs). Then we also discovered 18 BL Lac objects lying within the positional uncertainty regions of UGSs that could be their potential counterparts.

A Program to End the Drought in California
Creators: name: Jennings, John H.
Publisher: name: Zenodo
Year: 2022
Subjects: "California fire season" "classical nucleation theory" "homogeneous nucleation" rain "dew point" "relative humidity" "cloud seeding"

description: Here is a proposal to end California's fire season and alleviate the State's lack of precipitation. The mathematics stems from the author's research in classical nucleation theory, experimental and theoretical The Dew Point paper is also uploaded on Zenodo with John H. Jennings as sole author. It is a letter to California Governor Gavin Newsom to have a cloud seeding program over the clouds of the Sierra Nevada mountains to stimulate rain. Jennings' equation (9) in the Dew Point paper could be used to identify clouds ripe for cloud seeding with AgI, NaCl, or dry ice. An onboard computer would be fed certain quantities about a given cloud and if the temperature is near the dew point, then the plane will seed the cloud in the mountains.

description: The existence of a natural ultraviolet cutoff at the Planck scale is widely expected. In a previous Letter, it has been proposed to model this cutoff as an information density bound by utilizing suitably generalized methods from the mathematical theory of communication. Here, we prove the mathematical conjectures that were made in this Letter.

title: Comparative genome analyses of deuterostomes: Metabolism and base composities of tunicates, fish and mammals genomes
Creators: name: Zanotta, Luisa Berná
Publisher: name: The Open University
Year: 2011

description: The hypothesis that the metabolic rate could affect the base composition of genomes, i.e. the GC content, was tested along the phylogenetic line of deuterostomes, in the classes of tunicates, fish and mammals, by different approaches dictated by available data. Significant differences were found between the GC content of the completely sequenced genomes of C.intestinalis and C.savignyi. Interestingly, the increment was higher in C.savignyi in coding and non-coding regions, and mainly at the third codon positions (7% GC3). Methylation process and substitution rate were checked if responsible of the observed differences. The frequencies of CpG, CpA and TpG were no different between the two tunicates, and (even if tunicates showed a substitution rate 50% faster than that of vertebrates) the base composition was not directly affected. Multivariate analysis on codon usages showed that: i) in both species selection acts on codon usage, shaping translationally preferred codons between highly and lowly expressed genes; and ii) gene expression level affects the GC content of the two tunicate genomes. Data on the metabolic rate and the average genomic GC content were available for more than 200 teleostean species. Analyzing data according to the habitats, significant differences were found, with polar fish characterized by the highest metabolic rate and by a high GC content. A significant correlation was found between the two variables. Finally, intra-genome analyses of functional classes in more than ten mammalian genomes, confirmed the link between metabolism and GC content. In each mammalian genome, indeed, the average GC3 level was higher in genes involved in "metabolic processes". The same genome organization was not found in amphibians and reptiles, characterized by lower metabolic rates than mammals. The various approaches converged towards a coherent picture, highlighting the importance of metabolic rate as a factor shaping the base composition of genomes
Policies Affecting Educational Outcomes in Primary, Secondary, and Postsecondary Education

description: Education policy researchers have long sought to understand how various inputs of the education production function contribute to educational success, especially for those traditionally underserved populations. In three stand-alone essays (chapters), this dissertation will examine three such inputs of the education production function using quasi-experimental research methods. Chapter One uses Current Population Survey data for 1996-2016 and relies on difference-in-difference model specifications to estimate the effect of tuition subsidy policies on educational attainment and labor supply for Latino foreign-born noncitizens (FBNC) (i.e. proxy for undocumented youth) in high school. Primary findings show that eligibility for tuition subsidies lower Latino FBNC dropout rates, while providing access to state financial aid programs lowers dropout rates and increases labor supply. For tuition subsidy bans, however, I find some suggestive evidence of increasing dropout rates immediately following policy adoption. Implications of these findings suggest that signals from tuition subsidy policies do influence educational attainment and labor supply outcomes for those likely to be undocumented youth. Chapter Two uses data from a top-100 private, nonprofit college for 2005-2014 and relies on as-good-as-random assignment mechanisms to estimate the effect of professional academic advisor biological sex on early outcomes regarding academic performance (i.e., GPA and earned credit accumulation) and educational planning (i.e. changing majors and persistence). Primary findings show that cross-sex student-advisor matches affect male and female students differently; female students experience better academic performance (e.g. cumulative GPA), while male students change educational plans at lower rates. Implications from these findings suggest that colleges should ensure males and females are represented in advising services. Finally, Chapter Three uses Texas Education Agency data for 2003-2010 and relies on a synthetic control method to estimate the impact of a large worksite enforcement operation (LWEO) on academic performance for young children in a targeted community. Primary findings show the LWEO lowered proficiency rates on reading and math standardized tests for third grade children, and there is some evidence to suggest absenteeism drive effects. Implications from these findings suggest a need for revised immigration law enforcement strategies that both meets our immigration policy goals and minimizes harms inflicted on children.
