description: We classify 1-tilting classes over an arbitrary commutative ring. As a consequence, we classify all resolving subcategories of finitely presented modules of projective dimension at most 1. Both these collections are in 1-1 correspondence with faithful Gabriel topologies of finite type, or equivalently, with Thomason subsets of the spectrum avoiding a set of primes associated in a specific way to the ring. We also provide a generalization of the classical Fuchs and Salce tilting modules, and classify the equivalence classes of all 1-tilting modules. Finally we characterize the cases when tilting modules arise from perfect localizations.

A Skyrme Model with Novel Chiral Symmetry Breaking
Creators: name: Sutcliffe, Paul
Publisher: name: arXiv
Year: 2023
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: An extension of the Skyrme model is presented in which derivative terms are added that break chiral symmetry to isospin symmetry. The theory contains just one new parameter and it reduces to the standard Skyrme model when this symmetry breaking parameter vanishes. The same Faddeev-Bogomolny energy bound applies for all parameter values, but the parameter can be tuned so that the energy of the single Skyrmion is much closer to the bound than in the standard Skyrme model. Applying the rational map approximation to multi-Skyrmions suggests that, for a suitable value of the symmetry breaking parameter, binding energies in this theory may be significantly more realistic than in the standard Skyrme model.

Cosmic-Ray Hardenings in the Light of AMS-02

description: Recent precise observations of cosmic rays (CRs) by AMS-02 experiment clearly show (1) harder spectra of helium and carbon compared to protons by $\propto R^{0.08}$, and (2) concave breaks in proton and helium spectra at a rigidity $R \sim 300$ GV. In particular the helium and carbon spectra are exactly similar, pointing to the same acceleration site. We examine possible interpretations of these features and identify a chemically enriched region, that is, superbubbles as the most probable origin of Galactic CRs in high rigidity $R>30$ GV. The similar spectra of CR carbon and helium further suggest that the CRs with $R>30$ GV originate from the supernova ejecta in the superbubble core, mixed with comparable or less amount of interstellar medium. We predict similar spectra for heavy nuclei.

description: Gemcitabine is a potent radiosensitizer. When combined with standard radiotherapy (XRT) the gemcitabine dose must be reduced to about 10% of its conventional dose. Oxaliplatin and erlotinib also have radiosensitizing properties. In vitro, oxaliplatin and gemcitabine have demonstrated synergy. We aimed to determine the maximum tolerated dose of oxaliplatin and gemcitabine with concurrent XRT, then oxaliplatin, gemcitaibine and erlotinib with XRT in the treatment of locally advanced and low volume metastatic pancreatic or biliary cancer.
Relegation-free closed-form perturbation theory and the domain of secular motions in the Restricted 3-Body Problem

description: We propose a closed-form (i.e. without expansion in the orbital eccentricities) scheme for computations in perturbation theory in the restricted three-body problem (R3BP) when the massless particle is in an orbit exterior to the one of the primary perturber. Starting with a multipole expansion of the barycentric (Jacobi-reduced) Hamiltonian, we carry out a sequence of normalizations in Delaunay variables by Lie series, leading to a secular Hamiltonian model without use of relegation. To this end, we introduce a book-keeping analogous to the one proposed in Cavallari and Efthymiopoulos (2022) for test particle orbits interior to the one of the primary perturber, but here adapted, instead, to the case of exterior orbits. We give numerical examples of the performance of the method in both the planar circular and the spatial elliptic restricted three-body problem, for parameters pertinent to the Sun-Jupiter system. In particular, we demonstrate the method's accuracy in terms of reproducibility of the orbital elements' variations far from mean-motion resonances. As a basic outcome of the method, we show how, using as criterion the size of the series' remainder, we reach to obtain an accurate semi-analytical estimate of the boundary (in the space of orbital elements) where the secular Hamiltonian model arrived at after eliminating the particle's fast degree of freedom provides a valid approximation of the true dynamics.

Lingue senza consonanti bilabiali

Publisher: name: Universit� degli studi di Genova
Year: 2021

description: La presenza di consonanti nei punti d?articolazione velare, alveolare e bilabiale sembra rappresentare la base della costituzione di un sistema consonantico e viene descritta da diversi autori, secondo svariati approcci. Ciononostante sono presenti in letteratura, seppur in maniera piuttosto sporadica, riferimenti all?esistenza di lingue con una completa assenza di consonanti bilabiali, soprattutto da parte di autori dediti allo studio delle lingue native americane. Questo fa s�, pertanto, che la presenza di bilabiali non possa essere considerata un universale linguistico ma piuttosto una tendenza linguistica universale, che ammette , quindi, eccezioni. I riferimenti portati finora osservano il fenomeno da una prospettiva puramente sincronica, escludendo in tal modo, non soltanto le lingue estinte, ma anche quelle che hanno avuto un?assenza completa dei fonemi in questione in un momento lontano della propria storia, inserendoli successivamente nel proprio sistema consonantico. Sulla base di questo retroterra e di quanto emerso dal materiale consultato, la tesi si sviluppa principalmente sui tre seguenti punti. 1) La mappatura di tutte le lingue e famiglie linguistiche parlate o estinte, interessate in un qualsiasi momento della loro storia dal fenomeno, fornendo informazioni sulla distribuzione, genealogia e fonologia, con particolare attenzione, ovviamente, all?assenza di bilabiali. Questo primo obiettivo comprende anche una mappa digitale delle lingue, creata con l?utilizzo del software QGIS. 2) L?attribuzione di una completa assenza di bilabiali a quelle proto-lingue, la cui ricostruzione presentava punti oscuri proprio in merito a tali fonemi, nonch� una mancanza di unanimit� fra i diversi autori che le hanno studiate. Questo secondo obiettivo � stato perseguito principalmente attraverso studi tipologici. 3) Una descrizione delle caratteristiche della manifestazione del fenomeno secondo l?analisi delle diverse lingue e famiglie interessate e una ricerca della spiegazione delle cause che ne sono alla base.

description: Burkitt lymphoma (BL) is a highly aggressive non-Hodgkin lymphoma with a consistent MYC translocation. Epstein-Barr virus (EBV) has been associated with BL at different frequencies, depending on the clinical variant and geographic regions. This is a large-scale study of BL in Brazil, including 234 patients from 5 geographic regions that are widely disparate socioeconomically, including pediatric (61.1%) and adult (37.6%) populations. EBV was present in 52.6% of all BL cases, varying from 29% (12/42) in the South to 76% (13/17) in the North. Most of the cases were EBV type A. The frequency was higher in the pediatric group, and EBV association within this age range predominated in all regions except the South. Expression of p53 protein was observed in 16.2%, and only rare cases showed p63 expression. BL in Brazil is regionally distinct and has a low incidence of p53 overexpression and a higher-than-expected association with EBV in sporadic cases.

description: We study the existence of nonnegative solutions (and ground states) to the nonlinear Schrödinger equation in $\mathbb{R}^N$ with radial potentials and super-linear or sub-linear nonlinearities. The potentials satisfy power type estimates at the origin and at infinity, but no compatibility condition is required on their growth (or decay) rates at zero and infinity. In this respect our results extend some well known results in the literature and we also believe that they can highlight the role of the sum of Lebesgue spaces in studying nonlinear equations with weights.

The sterile neutrino that involves both mixing and transition magnetic moment may be a viable explanation for these high energy photon events. However, we demonstrate that such a solution is strongly disfavored by the cosmic microwave background (CMB) and Big Bang nucleosynthesis (BBN) in the standard cosmology.

Quantitative single-molecule mapping of neuronal proteins at the nanoscale
Creators: name: SCALISI, SILVIA
Publisher: name: Universit� degli studi di Genova
Year: 2020

description: The advent of super-resolution microscopy, also called nanoscopy, allowed a substantial improvement of spatial resolution, opening the door for the observation of biological structures beyond the diffraction limit impossible with conventional light microscopy. Among the super-resolution techniques, single-molecule localization microscopies have proven to be a powerful tool to address many biological issues, since they provide an imaging resolution of the order of tens of nanometers and the possibility to perform quantitative measurements. Neuroscience has been one of the fields in biology to benefit most from super-resolution microscopy. During the last years, single-molecule localization microscopies have been widely exploited to study diffraction-limited subcellular structures in neurons, allowing a deeper understanding of molecular mechanisms underlying neural network functioning and its impairments in pathologies. In this thesis, we developed a tool to investigate the distribution, spatial organization, clustering, and density of neural proteins at the nanoscale. In particular, we focused on the quantitative study of synaptic neurotransmitter receptors and focal adhesions. The knowledge of the distribution and stoichiometry of synaptic proteins is fundamental to understand the regulation of the synaptic transmission in neurons. However, a detailed characterization of the protein architecture within synapses can be achieved only by visualizing them at a nanometric level. Here we propose a quantitative approach based on stochastic optical reconstruction microscopy combined with cluster analysis to investigate the molecular rearrangement of GABAA receptors into subsynaptic domains during synaptic plasticity of the inhibitory neurotransmission. This approach was also applied to the study of the adhesion machinery of mammalian cells and neurons at the interface with single-layer graphene to investigate the interaction between cells and nanostructured materials. Due to their excellent properties and biocompatibility, graphene and its derivatives are the ideal candidates for many biomedical applications, such as neural tissue engineering. However, the adhesion processes at the graphene/neuron interface are still not clear nowadays. Our method offers an easy way to study how graphene substrates can affect adhesion and migration of different types of cells.
Measuring Time Costs in Interventions Designed to Reduce Behavior Problems Among Children and Youth

description: The economic evaluation of psychosocial interventions is a growing area of research. Though time costs are central to the economist’s understanding of social costs, these costs generally have been ignored by prevention scientists. This article highlights the need to measure such costs and then reviews the principles economists use in valuing time. It then considers the specific time costs that often arise in interventions designed to reduce behavior problems among children and youth. These include classroom time devoted to program activities, the time of parents or other caregivers, the time of teachers (outside of the classroom), and the time of volunteers. We consider the economic principles that govern how economists value these inputs and then apply these principles to data from an evaluation of a prominent intervention in the field, the Incredible Years Program. We find that the time costs are potentially rather large and consider the implications for public policy of ignoring them.

description: Understanding the viral dynamics and immunizing antibodies of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is crucial for devising better therapeutic and prevention strategies for COVID-19. Here, we present a Bayesian hierarchical model that jointly estimates the diagnostic RNA viral load reflecting genomic materials of SARS-CoV-2, the subgenomic RNAs (sgRNA) viral load reflecting active viral replication, and the rate and timing of seroconversion reflecting presence of antibodies. Our proposed method accounts for the dynamical relationship and correlation structure between the two types of viral load, allows for borrowing of information between viral load and antibody data, and identifies potential correlates of viral load characteristics and propensity for seroconversion. We demonstrate the features of the joint model through application to the COVID-19 PEP study and conduct a cross-validation exercise to illustrate the model's ability to impute the sgRNA viral trajectories for people who only had diagnostic viral load data.

description: A classical approach for the analysis of the longtime behavior of Markov processes is to consider suitable Lyapunov functionals like the variance or more generally $Φ$-entropies. Via purely analytic arguments it can be shown that these functionals are indeed non-increasing in time under quite general assumptions on the process. In this paper,we complement these classical results via a more probabilistic approach and show that dissipation is already present on the level of individual trajectories for spatially-extended systems of infinitely many interacting particles with arbitrary underlying geometry and compact local spin spaces. This extends previous results from the setting of finite-state Markov chains or diffusions in $\mathbb{R}^n$ to an infinite-dimensionalsetting with weak assumptions on the dynamics.

description: The purpose of this study was to identify potential opportunities for improving member participation in community-based coalitions. We hypothesized that opportunities for influence and process competence would each foster higher levels of individual member participation. We tested these hypotheses in a sample of 818 members within 79 youth-oriented coalitions. Opportunities for influence were measured as members’ perceptions of an inclusive board leadership style and members’ reported committee roles. Coalition process competence was measured through member perceptions of strategic board directedness and meeting effectiveness. Members reported three types of participation within meetings as well as how much time they devoted to coalition business beyond meetings. Generalized linear models accommodated clustering of individuals within coalitions. Opportunities for influence were associated with individuals’ participation both within and beyond meetings. Coalition process competence was not associated with participation. These results suggest that leadership inclusivity rather than process competence may best facilitate member participation.

description: One of the major puzzles regarding unconventional superconductivity is how some of the most interesting superconductors are related to an insulating phase that lies in close proximity. Here we report scanning tunneling microscopy studies of the local electronic structure of Cu doped NaFeAs across the superconductor to insulator transition. We find that in the highly insulating regime the electronic spectrum develops an energy gap with diminishing density of state at the Fermi level. The overall lineshape and strong spatial variations of the spectra are strikingly similar to that of lightly doped cuprates close to the parent Mott insulator. We propose that the suppression of itinerant electron state and strong impurity potential induced by Cu dopants lead to this insulating iron pnictide.

description: Estimates of the total particulate mass of the plumes of Enceladus are important to constrain theories of particle formation and transport at the surface and interior of the satellite. We revisit the calculations of Ingersoll & Ewald (2011), who estimated the particulate mass of the Enceladus plumes from strongly forward scattered light in Cassini ISS images. We model the plume as a combination of spherical particles and irregular aggregates resulting from the coagulation of spherical monomers, the latter of which allows for plumes of lower particulate mass. Though a continuum of solutions are permitted by the model, the best fits to the ISS data consist either of low mass plumes composed entirely of small aggregates or high mass plumes composed of mostly spheres. The high particulate mass plumes have total particulate masses of (166 $\pm$ 42) $\times$ 10$^3$ kg, consistent with the results of Ingersoll & Ewald (2011). The low particulate mass plumes have masses of (25 $\pm$ 4) $\times$ 10$^3$ kg, leading to a solid to vapor mass ratio of 0.07 $\pm$ 0.01 for the plume. If indeed the plumes are made of such aggregates, then a vapor-based origin for the plume particles cannot be ruled out. Finally, we show that the residence time of the monomers inside the plume vents is sufficiently long for Brownian coagulation to form the aggregates before they are ejected to space.

description: Contemporary social science paints a bleak picture of inner-city relational life. Indeed, the relationships of low-income, urban-residing Americans are represented as rife with distress, violence and family disruption. At present, no body of social scientific work systematically examines the factors that promote loving or selfless interactions among low-income, inner-city American individuals, families and communities. In an effort to fill that gap, this ethnographic study examined the motivations for altruism among a sample of adults (n = 40) who reside in an economically distressed housing community (i.e., housing project) in New York City. Content analyses of interviews indicated that participants attributed altruism to an interplay between 14 motives that were then ordered into four overarching categories of motives: (1) needs-centered motives, (2) norm-based motives deriving from religious/spiritual ideology, relationships and personal factors, (3) abstract motives (e.g., humanism), and (4) sociopolitical factors. The implications of these findings are discussed.
Psychosocial Correlates of Medical Mistrust Among African American Men

description: The current study proposed and tested a conceptual model of medical mistrust in a sample of African American men (N = 216) recruited primarily from barbershops in the Midwest and Southeast regions of the United States. Potential psychosocial correlates were grouped into background factors, masculine role identity/socialization factors, recent healthcare experiences, recent socioenvironmental experiences (e.g., discrimination), and healthcare system outcome expectations (e.g., perceived racism in healthcare). Direct and mediated relationships were assessed. Results from the hierarchical regression analyses suggest that perceived racism in healthcare was the most powerful correlate of medical mistrust even after controlling for other factors. Direct effects were found for age, masculine role identity, recent patient–physician interaction quality, and discrimination experiences. Also, perceived racism in healthcare mediated the relationship between discrimination experiences and medical mistrust. These findings suggest that African American men’s mistrust of healthcare organizations is related to personal characteristics, previous negative social/healthcare experiences, and expectations of disparate treatment on the basis of race. These findings also imply that aspects of masculine role identity shape the tone of patient–physician interactions in ways that impede trust building processes.

description: Supportive Non-Parental Adults (SNPAs), or non-parental adults who provide social support to youth, are present in the lives of many adolescents; yet to date, a guiding framework for organizing the existing literature on the provision of support provided by multiple types of SNPAS, such as teachers, natural mentors, and extended family members, as well as to inform future research efforts, is lacking. The aim of the current paper is to utilize the well-established lens of social support to integrate, across this broad range of literatures, recent findings regarding associations between SNPAs and four indices of adolescent psychosocial adjustment: academic functioning, self-esteem, and behavioral and emotional problems. Beyond offering an integrative framework for understanding the link between SNPAs and adolescent functioning, the issues reviewed here have potentially far-reaching consequences for adolescents and their families, as well as the professionals working with adolescents and their families in the health care, school, and community settings.
Analysis of the role of arginine methylation in the pathogenesis of Huntington?s disease

description: Huntington's disease (HD) is a fatal neurodegenerative disorder characterized by progressive loss of striatal and cortical neurons. HD is caused by an abnormal polyglutamine (polyQ) expansion in Huntingtin protein (HTT). HTT controls vesicular trafficking along axons in neurons through interaction with components of the molecular motor machinery. Arginine methylation is one of the most abundant post-translational modifications (PTMs) and is catalyzed by protein arginine methyltransferases (PRMTs). Recent evidence supports a key role for arginine methylation in neurodegeneration and particularly in polyglutamine diseases. However, whether HTT is methylated at arginine residues has not been investigated yet and the role of arginine methylation in HD pathogenesis remains to be fully elucidated. In this thesis, I show that vesicle-associated HTT is methylated in vivo at two evolutionarily conserved arginine residues, namely R101 and R118. Methylation of HTT at R118 is catalyzed by Protein Arginine Methyltransferase 6 (PRMT6), which localizes on vesicles together with HTT, whereas further analyses are required to identify the enzyme(s) responsible for R101 methylation. Interestingly, loss of PRMT6-mediated R118 methylation reduces the association of HTT with vesicles, impairs anterograde axonal transport and exacerbates polyQ-expanded HTT toxicity. Conversely, PRMT6 overexpression improves the global efficiency of anterograde axonal transport and rescues cell death in neurons expressing polyQ-expanded HTT. These findings establish a crucial role of arginine methylation as a modulator of both normal HTT function and polyQ-expanded HTT toxicity and identify PRMT6 as a novel modifier of HD pathogenesis. Importantly, defects in HTT methylation may contribute to neurodegeneration in HD and promoting arginine methylation of HTT might represent a new therapeutic strategy for HD.
Essays on Sell-Side Financial Analysts

description: Sell-side financial analysts play a crucial role as information intermediaries. On the one hand, by collecting, evaluating and disseminating value-relevant information, the analyst can influence the external information environment. On the other hand, the forecast performance of the analyst is affected by other important factors. This thesis focuses on the interaction between the central bank, the analyst and the external information environment. It includes three self-contained studies. Chapters 2 and 3 of this thesis explore the interplay between central bank monetary policy and analysts. Specifically, Chapter 2 examines the impact of the central bank’s monetary policy surprises on analysts’ earnings forecasts. Chapter 3 investigates how analysts interpret the private information embedded in the central bank’s monetary policy surprises and incorporate it into their earnings forecasts. Chapter 4 focuses on the role of the analyst in transmitting information across firms and further influencing firms’ investment decisions. This chapter explores how this process is affected by analysts’ research portfolios. Overall, this thesis contributes to the accounting, finance and macroeconomic literature by extending the understanding of financial analysts from different perspectives.

description: Kurd La�witz (1848-1910) fu personaggio eclettico, scrittore, filosofo, divulgatore scientifico, ma fu come narratore che fece breccia presso il largo pubblico, conquistandosi l?appellativo di �Jules Verne tedesco�. Nei racconti e nei saggi che sono qui presentati per la prima volta al pubblico italiano gli interessi molteplici di La�witz sono messi a fuoco e restituiti attraverso dispositivi narrativi che anticipano alcuni stilemi della moderna science fiction e li mettono in gioco attraverso una lente che usa procedimenti scientifici e gadget tecnologici per restituire un senso e una portata alla vicenda dell?esistenza umana. Rileggerli oggi, a distanza di cento e pi� anni dalla loro prima pubblicazione, significa mettere a fuoco un momento di passaggio decisivo sulla via di formazione del fantastico contemporaneo.
