Dark matter halo mergers and quasars

DARK MATTER HALO MERGERS AND QUASARS Jorge Moreno Ravi Sheth, Advisor The formation and evolution of galaxies and the supermassive black holes they harbor at their nuclei depends strongly on the merger history of their surrounding dark matter haloes. First we developed a semi-analytic algorithm that describes the merger history tree of a halo. The following tests were performed: the conditional mass function, the time and mass distributions at formation, and the time distribution of the last major merger. We provide a model for the creation rate of dark matter haloes, informed by both coagulation theory and the modified excursion set approach with moving barriers. A comparison with N-body simulations shows that our square-root barrier merger rate is significantly better than the standard extended Press-Schechter rate used in the literature. The last chapter is dedicated to a simple model of quasar activation by major mergers of dark matter haloes. The model consists of two main ingredients: the halo merger rate describing triggering, and a quasar light curve, which tracks the evolution of individual quasars. In this model, the mass of the seed black hole at triggering is assumed to be a fixed fraction of its mass at the peak luminosity. The light curve has two components: an exponential ascending phase and a power-law descending phase that depends on mass of ix the host. We postulate a self-regulation condition between the peak luminosity of the active galactic nucleus (AGN) and the mass of the host halo at triggering. This type of model for quasar evolution is at the heart of the latest semianalytic models (SAMs) of galaxy formation and it is therefore definitely worth studying in some detail. By carefully revisiting some of the main issues linked to this approach, we were able to derive several interesting and physically meaningful constraints regarding black hole evolution. We expect simple, yet observationally-constrained models like ours to play a central role in future models of galaxy formation.
Margins for error in context

According to the epistemic theory of vagueness defended in particular by Sorensen (2001) and Williamson (1994: 237), vagueness is due to our limited powers of discrimination: looking at a particular shade of red fabric, I may not be able to recognize that it is red, as a result of the specific granularity of my perceptual apparatus, which for instance makes the shade look somewhere between orange and red to me. Conversely, whenever I am confident that a particular shade of color is red, then this means that a slight variation in color should leave intact the fact that the shade is red. In Williamson's account of vagueness, this idea is expressed in terms of what Williamson calls margin for error principles for knowledge: whenever my knowledge is inexact in the sense of being approximative, it requires a sufficient margin for error in order to hold. More abstractly, the margin for error principle says that in order for me to know that some property P holds of an object d, then a slight modification of some relevant parameter in the object d should leave it in the extension of P . Expressed in terms of propositions and contexts, this means that in order to know that some proposition p holds in a context w, then p should still hold in a context w′ that is only slightly different from w. An important consequence of Williamson's margin for error semantics for inexact knowledge concerns the problem of iterations of knowledge. When applied to knowledge itself, the margin for error principle says that for me to know that I know p in a context w, I should know p in all contexts sufficiently similar to w. If knowledge is taken to be positively introspective, namely to be such that I know that I know p whenever I know p, then one can build a soritical argument to the effect that if I know p in a context w, then step by step, I should continue to know p even in contexts that are informationally very remote from w, including contexts in which p is false. For Williamson, the contradiction shows that knowledge, just like other mental states, is not luminous, namely that one can know p without knowing that one knows p. In Dokic & E gre (2004), an axiomatic version of Williamson's argument was challenged, resting on the idea that higher-order knowledge and first-order knowledge need not obey the samemarginsoferror.Morerecently,inBonnayE in section 2 we present a solution to the semantic version in the framework of Centered Semantics, a two-dimensional semantics for epistemic logic. We discuss in the following section the connection between Centered Semantics and actuality operators, and use this connection for the analysis of the syntactic version of the paradox. We conclude with some comparisons in section 4, in particular with Kamp's contextualist treatment of the sorites.
Upcycling Discarded Shoe Polish into High Value-Added Asphalt Fluxing Agent for Use in Hot Mix Paving Applications

This research effort is geared towards revealing the latent potential of discarded shoe polish that might be repurposed as an asphalt fluxing agent for the construction of durable and sustainable road surfaces. To drive this creative invention, the effect of various proportions of waste shoe polish (e.g., 5, 10 and 15 wt. % WSP) on the performance of base AP-5 bitumen was inspected in great detail. A meticulous investigation of the chemical, physical, and rheological properties of the resultant combinations was carried out using a variety of state-of-the-art laboratory techniques, specifically: thin-layer chromatography-flame ionization detection (TLC-FID), Fourier transform-infrared spectroscopy (FT-IR), needle penetration, ring-and-ball softening point, Brookfield viscometer, ductility, flash/fire points, dynamic shear rheometer (DSR), multiple stress-creep recovery (MSCR), and bending beam rheometer (BBR) tests. The Iatroscan data disclosed that the continuous feeding of binder with WSP had a minor impact on SARA fractional distribution, regardless of aging. According to the FT-IR scan, the stepwise addition of WSP to the binder did not result in any significant chemical alterations in the blends. The combined outcomes of the DSR/BBR/empirical test methods forecasted that the partly bio-sourced additive would greatly improve the mixing–compaction temperatures, workability, and coating–adhesion properties of bituminous mixtures while imparting them with outstanding anti-aging/cracking attributes. In short, the utilization of waste shoe polish as a fluxing agent for hot asphalt mix production and application is not only safe, feasible, and affordable, but it has the potential to abate the pollution caused by the shoe-care market while simultaneously enhancing the overall performance of the pavement and extending its service lifespan.
Effects of At-Home and In-Office Bleaching Agents on the Color Recovery of Esthetic CAD-CAM Restorations after Red Wine Immersion

The aim of this study was to evaluate the effects of at-home and in-office bleaching agents on esthetic CAD-CAM materials after red wine immersion by measuring their optical properties. Sixty specimens were prepared out of three esthetic CAD-CAM materials: Vita Enamic, Celtra Duo, and Ceresmart (n = 20). All specimens were immersed in a red wine solution, and color measurements were performed. Specimens were randomly divided (n = 10) according to the bleaching procedure (in office, at home), bleaching durations were set to 3 time points, and color measurements were performed. According to the Commission Internationale de l’Eclairage (CIE) L* a* b* parameters, CIEDE2000 color differences (ΔE00), translucency parameters (TP00), and whiteness index values (ΔWID) after wine staining and after bleaching were calculated. Data were analyzed using the Mann–Whitney U-test, the Kruskal–Wallis test, and a two-way analysis of variance (ANOVA) (α = 0.05). ΔE00, ΔTP00, and ΔWID decreased with an increase in bleaching treatment. ΔE00 after the final bleaching treatment of in-office bleaching ranged from 1.7 to 2.0, whereas those of in-office treatment ranged from 0.4 to 1.1. All ΔTP00 and ΔWID after the final treatment were below the 50:50% perceptibility thresholds (ΔTP00 < 0.6, and ΔWID < 0.7). Significant differences in ΔE00, ΔTP00, and ΔWID among esthetic CAD-CAM materials were found between CD and CE. In the present study, color recovery after at-home and in-office bleaching appeared to be material-dependent. In-office bleaching showed more effective recovery comparing to at-home bleaching.
Large-Area Ordered Palladium Nanostructures by Colloidal Lithography for Hydrogen Sensing

Reliable gas sensors are very important for hydrogen (H2) gas detection and storage. Detection methods based on palladium (Pd) metal are cost-effective and widely studied. When Pd is exposed to H2, it turns into palladium hydride with modified optical properties, which thus can be monitored for H2 sensing. Here, we fabricated large-area Pd nanostructures, including Pd nanotriangles and nanohole arrays, using colloidal lithography and systematically studied their H2-sensing performance. After hydrogen absorption, both the Pd nanoholes and nanotriangles showed clear transmittance changes in the visible–near infrared range, consistent with numerical simulation results. The influences of the structural parameters (period of the array P and diameter of the nanohole D) of the two structures are further studied, as different structural parameters can affect the hydrogen detection effect of the two structures. The nanohole arrays exhibited bigger transmittance changes than the nanotriangle arrays.
The impact of economic policy uncertainty and financial development on the sensitivity of corporate cash holding to cash flows

ABSTRACT The paper examines how economic policy uncertainty and financial development affect a firm’s cash-holding policy before and after the global financial crisis. Using Chinese nonfinancial firm data from 1997 to 2018, we obtain three main findings. First, economic policy uncertainty increases corporate cash holdings and its sensitivity to operating cash flows. Second, financial institution and market developments reduce corporate cash-holdings’ cash flow sensitivity. Third, the impact of economic policy uncertainty on corporate cash-holdings’ sensitivity to operating cash flows decreases with financial development. Firms adjust their cash-holding policy in response to changes in economic policy uncertainty and financial development, indicating that macroeconomic factors determine the precautionary motive for holding cash.
Effect-Directed Profiling of Strawberry Varieties and Breeding Materials via Planar Chromatography and Chemometrics

Strawberries are an important fruit in the European diet because of their unique taste and high content of essential nutrients and bioactive compounds. The anthocyanins are known to be colorful phenolics in strawberries. In 17 samples of six strawberry cultivars produced in Serbia, i.e., the common varieties Alba, Asia, and Clery as well as promising breeding materials (11.29.11, 11.34.6, and 11.39.3), the anthocyanin profile as well as antimicrobial and antioxidative activity profiles were determined. All investigated extracts showed antioxidative and antibacterial activities against Gram-negative Aliivibrio fischeri. The responses were quite similar in number and intensity. The HPTLC-DPPH• scavenging assay and HPTLC-Aliivibrio fischeri bioassay coupled with high-resolution mass spectrometry identified pelargonidin-3-O-glucoside (Pg-3-glc) as the main anthocyanin and prominent antioxidative and antimicrobial compound in strawberries. The density functional theory calculations at the M06-2X/6-31+G(d,p) level showed that Pg-3-glc quenches free radicals via sequential proton loss electron transfer mechanism in water and in pentyl ethanoate, where the 5-OH group is the most reactive site for proton and hydrogen atom transfer. The results were confirmed via spectrophotometry. The highest total phenolic content was found in Clery and 11.39. 3, while statistically significant differences between the genotypes regarding the antioxidant activity were not confirmed. Although very similar in the anthocyanin, antioxidative, and antimicrobial profile patterns, the strawberry genotypes were successfully classified using principal component analysis.
Zygo-Albuside A: New Saponin from Zygophyllum album L. with Significant Antioxidant, Anti-Inflammatory and Antiapoptotic Effects against Methotrexate-Induced Testicular Damage

Chemical investigation of the crude extract of the aerial part of Zygophyllum album L. (Z. album) led to the isolation of a new saponin, Zygo-albuside A (7), together with seven known compounds, one of them (caffeic acid, compound 4) is reported in the genus for the first time. NMR (1D and 2D) and mass spectrometric analysis, including high-resolution mass spectrometry (HRMS), were utilized to set up the chemical structures of these compounds. The present biological study aimed to investigate the protective antioxidant, anti-inflammatory, and antiapoptotic activities of the crude extract from the aerial part of Z. album and two of its isolated compounds, rutin and the new saponin zygo-albuside A, against methotrexate (MTX)-induced testicular injury, considering the role of miRNA-29a. In all groups except for the normal control group, which received a mixture of distilled water and DMSO (2:1) as vehicle orally every day for ten days, testicular damage was induced on the fifth day by intraperitoneal administration of MTX at a single dose of 20 mg/kg. Histopathological examination showed that pre-treatment with the crude extract of Z. album, zygo-albuside A, or rutin reversed the testicular damage induced by MTX. In addition, biochemical analysis in the protected groups showed a decrease in malondialdehyde (MDA), interleukin-6 (IL-6) and IL-1β, Bcl-2-associated-protein (Bax), and an increase in B-cell lymphoma 2 (Bcl-2) protein, catalase (CAT), superoxide dismutase (SOD) in the testis, along with an increase in serum testosterone levels compared with the unprotected (positive control) group. The mRNA expression levels of nuclear factor-kappa B (NF-κB), tumor necrosis factor-α (TNF-α), p53, and miRNA-29a were downregulated in the testicular tissues of the protected groups compared with the unprotected group. In conclusion, the study provides sufficient evidence that Z. album extract, and its isolated compounds, zygo-albuside A and rutin, could alleviate testicular damage caused by the chemotherapeutic agent MTX.
Etingof conjecture for quantized quiver varieties II: affine quivers

We study the representation theory of quantizations of Gieseker moduli spaces. Namely, we prove the localization theorems for these algebras, describe their finite dimensional representations and two-sided ideals as well as their categories O in some special cases. We apply this to prove our conjecture with Bezrukavnikov on the number of finite dimensional irreducible representations of quantized quiver varieties for quivers of affine type.
Perceived Physical Education Teachers’ Controlling Behaviour and Students’ Physical Activity during Leisure Time—The Dark Side of the Trans-Contextual Model of Motivation

Background: Previous studies have shown that the controlling behaviour of physical education teachers might be detrimental to their students’ psychological experiences. The purpose of this work was to examine whether and to what extent the different dimensions of the perceived controlling teaching questionnaire predict students’ basic psychological needs, motivations, and physical activities during leisure-time. Methods: A total of 299 students (164 boys and 135 girls) from four Estonian general education schools and two vocational education institutions participated in the study. Students filled in the questionnaire of study variables. A variance-based structural model was used to test the research hypotheses. Results: The results revealed that different forms of controlling behaviours predicted psychological need frustration (β = 0.09–0.37; p < 0.01). Psychological need frustration predicted controlled motivation (β = 0.52; p < 0.01). Controlled motivation predicted subjective norms (β = 0.51; p < 0.01). Intention was predicted by attitudes (β = 0.30; p < 0.01), perceived behavioural control (β = 0.37; p < 0.01), and subjective norms (β = 0.15; p < 0. 01). Attitude was statistically significantly related to leisure-time physical activity (β = 0.09; p < 0.05). The model describes 10% of students’ physical activity in the context of leisure-time. Conclusion: The results of this study highlight that physical education teachers should avoid using controlling behaviours if the aim is to avoid frustrating their students’ psychological needs, which might have detrimental effect on students’ leisure-time physical activity via controlled forms of motivation.
Exploration of Multilevel Barriers and Strategies That Affected Early COVID-19 Vaccination and Testing in Rural Latino Communities in Southwest Florida

The COVID-19 pandemic has disproportionately impacted multiple racial and ethnic minority groups, including Latinos residing in rural communities. Low rates of vaccination and testing combined with social determinants of health have contributed significantly to this disparate impact. Given the needs and constraints unique to rural Latino migrant and immigrant communities, this qualitative study examined multilevel barriers and strategies that affect COVID-19 vaccination and testing uptake among these communities in southwest Florida. Four focus groups (n = 25) were conducted between March and April 2021 with various key stakeholders, including rural Latino community members, local leaders, and community health workers (‘Promotoras de Salud’). Themes that aligned with barriers to COVID-19 vaccination and testing included fear, lack of control, misinformation, lack of accessibility, and institutional/policy issues; themes that aligned with strategies to improve COVID-19 vaccination and testing uptake included faith, taking care of self, and community and family resilience. Recommendations for improving future pandemic responses for rural Latino communities include incorporating multiple levels of intervention, such as consideration of the role of the family, involving trusted community members, and ensuring the development and implementation of fair and consistent policies.
Solvent Exchange around Aqueous Zn(II) from Ab Initio Molecular Dynamics Simulations

Hydrated zinc(II) cations, due to their importance in biological systems, are the subject of ongoing research concerning their hydration shell structure and dynamics. Here, ab initio molecular dynamics (AIMD) simulations are used to study solvent exchange events around aqueous Zn2+, for which observation in detail is possible owing to the considerable length of the generated trajectory. While the hexacoordinated Zn(H2O)62+ is the dominant form of Zn(II) in an aqueous solution, there is a non-negligible contribution of the pentacoordinated Zn(H2O)52+ complex which presence is linked to the dissociative solvent exchange events around Zn2+. The pentacoordinated Zn(II) has a much tighter hydration sphere and is characterized by a trigonal bipyramidal structure, in contrast to the usual octahedral symmetry of the hexacoordinated complex. In total, two full exchange events are registered in the analyzed trajectory. AIMD simulations on an adequate length scale thus provide a direct way of studying such solvent exchange events around ions in molecular detail.
Datterino Trial: A Double Blind, Randomized, Controlled, Crossover, Clinical Trial on the Use of Hydroponic Cultivated Tomato Sauce in Systemic Nickel Allergy Syndrome

A low-nickel (Ni) diet, a key treatment for Systemic Nickel Allergy Syndrome (SNAS), is difficult in the long term and strongly impacts quality of life (QoL). Hydroponic agriculture could be an alternative to allow the reintroduction of tomato, an essential food in the global diet. In a first interventional, randomized, double-blind, single-center crossover study, we compared the possible effects of eating tomato puree deriving from hydroponic agriculture versus tomato puree from conventional cultivation, collecting data on subjective control of SNAS symptoms, adherence to treatment, and impact on QoL. Thirty subjects were randomly assigned to one of the following treatment groups: (1) a 12-week low-Ni diet plus 100% Italian Datterino tomato puree deriving from hydroponic technology; (2) a 12-week low-Ni diet plus 100% Italian Datterino tomato puree deriving from conventional cultivation. Then, after a 2-week washout period on the low-Ni diet, each patient crossed over to the other treatment. Patients reported lower symptom scores after eating Datterino tomato puree deriving from hydroponic technology; specifically, bloating (p = 0.0111, p = 0.0060), flatulence (p = 0.0090), abdominal cramps (p = 0.0207), constipation (p = 0.0395), and diarrhea (p = 0.0105). Overall, the adherence rate was high for both treatment arms. At baseline, QoL was poor, but significant improvement was observed after two treatments. In our study, precision medicine and precision agriculture merge in a holistic approach to the challenges of food allergies.
