description: This thesis documents the results of a PhD research project which focuses on investigating the underlying psychological processes that can explain adults’ motivations for listening to self-identified sad music when feeling sad. Even though people do often listen to sad music when feelings sad, surprisingly little research has been conducted to investigate the psychological processes that can explain this behaviour or the effects of deciding to listen to sad music when feeling sad. The research presented in the current thesis sought to fill this void.Following an introduction to the topic and methods (Chapter 1) and a review of relevant and recent literature (Chapter 2), three chapters (Chapter 3; Chapter 4; Chapter 5) detail the results of a systematic empirical study on people’s sad music listening behaviour, their rationally for engaging in this behaviour and the self-reported effects of this behaviour. Then a discussion chapter (Chapter 6) is included in which al the findings are summarized and discussed. In the discussion chapter, limitations of the empirical studies will additionally be discussed and recommendations will be made for future research.
The quantization of unimodular gravity and the cosmological constant problem
Creators: name: Smolin, Lee
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A quantization of unimodular gravity is described, which results in a quantum effective action which is also unimodular, ie a function of a metric with fixed determinant. A consequence is that contributions to the energy momentum tensor of the form of the metric times a spacetime constant, whether classical or quantum, are not sources of curvature in the equations of motion derived from the quantum effective action. This solves the first cosmological constant problem, which is suppressing the enormous contributions to the cosmological constant coming from quantum corrections. We discuss several forms of uniodular gravity and put two of them, including one proposed by Henneaux and Teitelboim, in constrained Hamiltonian form. The path integral is constructed from the latter. Furthermore, the second cosmological constant problem, which is why the measured value is so small, is also addressed by this theory. We argue that a mechanism first proposed by Ng and van Dam for suppressing the cosmological constant by quantum effects obtains at the semiclassical level.

Regional geology, groundwater flow systems and slope stability
Creators: name: Hodge, Robert A.L.
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis is to show, using computer simulation of flow systems in a variety of hypothetical slopes, how different geological environments affect the groundwater flow regime, which in turn is fundamental to the stability of a slope. Galerkin's method is used to derive a finite element program to model two dimensional, saturated, steady state flow through anisotropic and heterogeneous rigid porous media. An understanding of the regional geology is required in order to understand the regional flow system. The following points are illustrated. a. In anisotropic media, the most adverse groundwater condition for slope stability occurs when the major axis of conductivity lies down the dip of the slope. b. Depending on their characteristics, faults, contacts and dykes can be either detrimental or favourable in their effect on the flow system. Careful field investigation is required to establish that effect. c. Deep weathering commonly causes a confining zone of low conductivity, a situation very detrimental to stability. d. Stress relief fractures on valley walls can adversely influence the effect of groundwater on stability. e. A regional aquifer can cause high pore pressure development beneath a valley. f. Fluctuations in the regional groundwater system can cause instability in Pleistocene terraces. g. The presence of an underlying less conductive zone or unit can have an adverse effect on the flow system. Conductivity contrasts of less than two orders of magnitude can cause pore pressure development critical to stability. Three other points are demonstrated which have direct application to slope stability analysis and control. 1. The pressure head distribution on rock wedges can be nonlinear rather than the commonly assumed linear distribution. 2. The introduction of a reservoir at the toe of a slope can influence the groundwater regime well above the reservoir surface; even a low reservoir can cause, the change required to cause instability. 3. Piezometric measurements and drainage systems must penetrate through any less conductive unit that might be acting as a slide plane.

description: The thesis investigated the topic of localised retail design. The problem was to gain an understanding of the conditions and strategies for localising retail design for global brands. Localised retail design is the design of physical retail stores that respond to their location. When localising retail design, the conditions of retaining global brand consistency and mediating global brand and local authenticity require consideration. These have been partially addressed in the discourse. Although several global brands practice localised retail design, there is limited documentation of these design strategies within the discourse. This demonstrates a gap between the theory and practice of localised retail design. The study aimed to address this by developing conditions and determining strategies for localising retail design for global brands. The research objectives were to clarify the ways in which global brand consistency can be retained when localising retail design; identify areas in which global brand and local authenticity may be mediated when localising retail design; and determine strategies for localising retail design for global brands. Semi-structured interviews with 18 retail designers and a documentation of 20 artefacts of localised retail design for four global brands were conducted and analysed using the constructivist grounded theory method. The study findings were: The conditions for retaining global brand consistency are consistencies in designer choice; consistencies in approaches to localising retail design; and creating global brand manuals with scope to localise retail design. The areas for mediating global brand and local authenticity are in authorship; informants; and inhabitation of retail design. The strategies for localising retail design for global brands are local creative collaboration; locally responsive design; and local consumer relevant experience. The study contributes new knowledge through developing conditions and determining strategies for localising retail design for global brands. This has implications on the theory and practice of retail design.

description: We present a comprehensive multiwavelength investigation of a likely massive young cluster `IRAS 05100+3723' and its environment with the aim to understand its formation history and feedback effects. We find that IRAS 05100+3723 is a distant ($\sim$3.2 kpc), moderate mass ($\sim$500 \msun), young ($\sim$3 Myr) cluster with its most massive star being an O8.5V-type. From spectral modeling, we estimate the effective temperature and log $g$ of the star as $\sim$33,000 K and $\sim$3.8, respectively. Our radio continuum observations reveal that the star has ionized its environment forming an HII region of size $\sim$2.7 pc, temperature $\sim$5,700 K, and electron density $\sim$165 cm$^{-3}$. However, our large-scale dust maps reveal that it has heated the dust up to several parsecs ($\sim$10 pc) in the range 17$-$28 K and the morphology of warm dust emission resembles a bipolar HII region. From dust and $^{13}$CO gas analyses, we find evidences that the formation of the HII region has occurred at the very end of a long filamentary cloud around 3 Myr ago, likely due to edge collapse of the filament. We show that the HII region is currently compressing a clump of mass $\sim$2700 \msun at its western outskirts, at the junction of the HII region and filament. We observe several 70 $μ$m point sources of intermediate-mass and class 0 nature within the clump. We attribute these sources as the second generation stars of the complex. We propose that the star formation in the clump is either induced or being facilitated by the compression of the expanding HII region onto the inflowing filamentary material.

description: We investigate a model for the dynamics of ellipsoidal microswimmers in an externally imposed, laminar Kolmogorov flow. Through a phase-space analysis of the dynamics without noise, we find that swimmers favor either cross-stream or rotational drift, depending on their swimming speed and aspect ratio. When including noise, i.e. rotational diffusion, we find that swimmers are driven into certain parts of phase space, leading to a nonuniform steady-state distribution. This distribution exhibits a transition from swimmer aggregation in low-shear regions of the flow to aggregation in high-shear regions as the swimmer's speed, aspect ratio, and rotational diffusivity are varied. To explain the nonuniform phase-space distribution of swimmers, we apply a weak-noise averaging principle that produces a reduced description of the stochastic swimmer dynamics. Using this technique, we find that certain swimmer trajectories are more favorable than others in the presence of weak rotational diffusion. By combing this information with the phase-space speed of swimmers along each trajectory, we predict the regions of phase space where swimmers tend to accumulate. The results of the averaging technique are in good agreement with direct calculations of the steady-state distributions of swimmers. In particular, our analysis explains the transition from low-shear to high-shear aggregation.

In this work, we show the results of a stellar population modeling in a datacube taken with the Gemini South telescope. We found that $\sim$ 90% of the light in the field of view is emitted by stars that are less than 1 billion years old. A strong burst occurred about $\sim$ 6 million years ago and has nearly solar metallicity. We also found a Wolf-Rayet cluster.

description: We present experimental observations of strong electric and magnetic interactions between split ring resonators (SRRs) in metamaterials. We fabricated near-infrared (1.4 $μ$m) planar metamaterials with different inter-SRR spacings along different directions. Our transmission measurements show blueshifts and redshifts of the magnetic resonance, depending on SRR orientation relative to the lattice. The shifts agree well with a simple model with simultaneous magnetic and electric near-field dipole coupling. We also find large broadening of the resonance, accompanied by a decrease in effective cross section per SRR with increasing density. These effects result from superradiant scattering. Our data shed new light on Lorentz-Lorenz approaches to metamaterials.

China’s Foreign Policy in the ‘Going Out’ Era: An Analysis of China’s Zambia Policy

description: This dissertation analyses Chinese foreign policymaking in the context of Sino-Zambian relations in the ‘Going Out’ era (1997-2022). China’s foreign policymaking system tends to be regarded as a ‘black box’ by foreign observers, owing to their limited access to it. In particular, Western researchers’ ability to understand Chinese foreign policymaking is stymied by impediments such as language barriers and difficulties in gaining access to key actors inside the system. Unusually in this context, this dissertation presents the findings of twelve elite interviews with senior officials that shed new light on the Chinese foreign policymaking process. Situated theoretically within a fragmented authoritarianism framework that rejects the conventional image of Chinese foreign policymaking as centralised, top-down, and highly coordinated, the dissertation instead explores how Chinese foreign policy is made “on the ground,” with all the messiness, confusion, and contradictions this entails. In the process, the dissertation develops the concept of “policy lagging” in order to explain some of the notable failures of China’s foreign policy when it comes to Zambia. It finds that China’s foreign policymaking system is surprisingly ineffective at coordinating the various actors involved in the process. Furthermore, communication between those actors is compromised by a system of policy-related information flows that is not fit for purpose. China’s foreign policymaking system proves to be insufficiently proactive: policy adoptions are slow to occur, and important matters escalate before resolutions can be found. These problems are exacerbated by policymakers’ willingness to justify policy failures and their unwillingness to make timely policy adaptions.

IMPROVING EMOTION REGULATION THROUGH METACOGNITION AND MINDFULNESS: DEVELOPING A PRIMARY SCHOOL-BASED INTERVENTION

description: The present research explores the effects of school-based metacognition and mindfulness interventions to improve emotion regulation in primary school children. Children with effective emotion regulation skills have better outcomes in wellbeing, academic achievement and life-satisfaction. Improving regulation skills can help to prevent depression, anxiety and other mental health disorders. Previous literature suggests that emotion regulation can be improved by mindfulness interventions, delivered in primary-school settings. Mindfulness-Based Interventions (MBIs) tend to be a combination of taught material and meditative practice but it is unclear how each of these elements contribute to outcomes. Felver et al. (2016) suggested that an exploration of these different elements would be beneficial, and this exploration forms the basis of this thesis.A series of five quasi-randomised controlled trials were carried out to explore the effects of a classroom-based mindful meditation alone, and in combination with a structured thinking activity or a separate taught component. Finally the effectiveness of a pre-recorded integrated programme, combining mindful meditation and a taught component was examined. Measures were included on attentional outcomes (selective and sustained attention, and mindful awareness), cognitive appraisal (emotion recognition, anxiety and affect) and emotional response (academic outcomes, coping and anger). Each study included 9-11 year old children who attended mainstream schools.The findings from the experimental series suggest that mindfulness based interventions do significantly improve aspects of emotion regulation. However, mindfulness based interventions with a taught component (MBI+) are more effective than mindfulness alone. MBI+ showed improvement across attentional outcomes, cognitive appraisal and emotional response. This was the case for both classroom-based and pre-recorded delivery.To better understand the mechanisms of change, future research needs to provide in-depth, qualitative knowledge of pre-adolescent participants’ application of mindfulness and metacognitive strategies. With the increasing mental health challenges evident in primary schools, due in part to the COVID 19 pandemic, the effectiveness and feasibility of a pre-recorded programme should be explored further. This mode of delivery would mitigate some of the challenges surrounding staff knowledge and expertise within the primary school environment.

Variational formulation and finite element type solution for free oscillations of a rotating laterally heterogeneous earth
Creators: name: Moon, Wooil
Publisher: name: University of British Columbia
Year: 2010

description: A variational type, finite element method is proposed for the study of normal modes of a rotating, laterally heterogeneous Earth. This method is very powerful and, in theory, overcomes all the limitations of the perturbation method. However, the present size of computer memory puts severe limitations on the use of this method. The Lagrangian energy integral is derived for a general configuration of a perfectly elastic continuum in both shperical and oblate ellipsoidal coordinate systems. The assumed solutions for the displacements and the perturbation of the gravitational potential are formed by tensor products of the cubic Hermite basis functions of three coordinate variables. The undetermined coefficients of these assumed solutions are solved by the minimization of the Lagrangian energy integral by a Rayleigh-Ritz technique. The results of the numerical solution of this approach show that (1) this algorithm is very efficient and promising in one-dimensionalized normal mode problems, (2) that the degenerate frequency of [sub n]W[sub ℓ][sup m] splits into (2ℓ+1) components, even for the non-rotating, homogeneous spherical Earth model, due to the interpolation scheme of the azimuthal basis functions and (3) because the numerical spectral splitting is very large, the effects of self-gravitation and rotation cannot be examined clearly in this study. However, lateral heterogeneities which break the symmetry of the physical shape of the Earth greatly affect the normal mode spectra.

description: Scientists, scientific organisations and government committees have identified a lack of responsible science and environmental journalism in many parts of the mass media; pointing, for example, to problems of accuracy, distorted facts and misrepresentation. The resulting tensions between those engaged in the processes of scientific inquiry and journalistic practice have been attributed, in part, to a gulf of mutual incomprehension between people who inhabit different disciplinary territories, exhibiting separate professional and cultural identities. In the context of a discussion of critical pedagogy which underpins the research, the theory of borders and borderlands is introduced as a way to conceptualise and explain problems which occur in this kind of cultural clash, and also to consider how they might be addressed in an educational context.The research first explores the role of science journalists in a changing media landscape, exploring the economic and technological challenges they face, and the nature of their relationship with scientists, in order to identify implications for the design of university science journalism programmes. A qualitative approach is taken, with two strands consisting of a series of in-depth, semi-structured interviews, broadly representing science journalists and those who run university science journalism courses; and a participant observation with a mixed-cohort of journalism and science students.Scholars and practitioners highlight the complexity and interconnectedness of many aspects of science and environmental reporting, as well as the broad range of subject areas the field encompasses. Participants underline the importance for scientists and journalists to foster long-term positive professional relationships, and to initiate these at an early stage. For these reasons, science journalism tutors are encouraged to make opportunities within the curriculum to promote interdisciplinary connections and collaboration.A range of interdisciplinary models is presented from which educators can select, depending on student needs, educational context and goals. In particular, collaborative initiatives with science students were found to be effective in helping science journalism students develop their knowledge and understanding of the language and culture of science, and of the processes of scientific research and publishing. There were similar benefits for science students in the form of enhanced awareness of journalistic processes. The author outlines a framework, drawing on border pedagogy principles, which can be applied as a template in other contexts for designing similar transformational learning experiences.
LA RISPOSTA UMANITARIA AL FENOMENO MIGRATORIO. STUDIO ETNOGRAFICO DI UN CAMPO NEL NORD D'ITALIA
Creators: name: JACQMIN, ARIANNA
Publisher: name: Universit� degli Studi di Milano

description: This research investigates the camp for migrants as a political-humanitarian device to face immigration. It is claimed that humanitarianism, a theoretical approach and a set of interventions to face the other?s suffering, has expanded its domain of action from war context to everyday political life, though without losing its nature: it is an immediate, temporary, and exceptional reaction to face an emergency. In this respect, Italian migration policies offer a fertile field of study, where humanitarianism proposes a way to manage and, at the same time, to understand (a certain kind of) immigration. In the local and actual context, as it used to happen in conflict times, the primary instrument of humanitarian intervention is the camp. It is a space of protection of real or assumed victims (of war or of forced migration) and, yet, of their limitation, not only from a geographical point of view. In this research, the literature on humanitarianism, its development, action and rhetoric, meets with theoretical and empirical studies on present migrant camps in Europe and in particular in Italy, dealing with them from a main socio-legal perspective, but considering them also in philosophical, anthropological, and geographical terms. Theoretical considerations over humanitarian reaction to migration find support in an ethnographic study the author conducted from November 2016 to October 2017 in a Red Cross migrant camp in the town of Como (North of Italy). Spaces within this camp are analysed through the concept of the ?service?, i.e. the performance of rituals to assist migrants, which embodies the essence of humanitarianism. The observed place represents a model of migrant ?humanitarian camp?, a conceptual tool to understand and criticize a growing number of alike spaces in Europe.
IMPOSSIBILIT� NEL DIRITTO

Year: 2014

description: My Ph.D. thesis ?Impossibilit� nel diritto? [Impossibility in the Legal Domain] is devoted to the systematic analyses of what are called, at least prima facie, ?legal impossibilities?. My dissertation defines and isolates an area of studies - impossibility in the law - that has never been put organically together. In my work I present some case studies of normative impossibilities and discuss them from a philosophical point of view: impossible laws, impossible norms in a prescriptive theory of norms (ch. 2), conflicting norms and legal gaps (metanormative impossibility - ch. 3), impossible obligations (ch. 4), impossible crimes (ch. 5), impossible legal proofs (ch. 6). I organize my research along the distinction ? introduced in ch. 1 ? between impossibility of norms (i.e. impossible norms and impossible normative acts) and impossibility from norms (i.e. impossibility due to a norm or a set of norms); the distinction between the impossibility of a norm conceived as a single entity and the impossibility of a norm conceived as part of a legal system; and the distinction of two uses of impossibilities in general, as impossibility can be both the object of a modal qualification and a modality itself. I propose four new contributions to the study of impossibility in the legal domain (ch. 7). Firstly, I reconstruct two different functions of the impossibility in the legal domain (exculpatory and invalidating); secondly, I put forward a triadic model for describing impossibility in the legal domain (in which, roughly, a set of sources of impossibilities is qualified by a function for the assumption of impossibility in the actual and concrete legal system); thirdly, I define and investigate the relationship of creation, assumption and presupposition between impossibility and a legal system; fourthly, I critically list and review all the different kinds of things that are called ?impossibilities? inside a legal system, showing how sometimes the use of the concept of impossibility is not carefully justified. As an appendix (ch. 8), I outline a logic for impossibilities in the legal domain that allows to investigate the phenomena discussed in the work by breaking down the equivalence between being impossible (in the legal domain) and being logically contradictory.

description: [ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be 50 times more sensitive than any existing radio facility. A majority of the key science for the SKA will be addressed through large-area imaging of the Universe at frequencies from 300 MHz to a few GHz. The Australian SKA Pathfinder (ASKAP) is aimed squarely in this frequency range, and achieves instantaneous wide-area imaging through the development and deployment of phase-array feed systems on parabolic reflectors. This large field-of-view makes ASKAP an unprecedented synoptic telescope poised to achieve substantial advances in SKA key science. The central core of ASKAP will be located at the Murchison Radio Observatory in inland Western Australia, one of the most radio-quiet locations on the Earth and one of the sites selected by the international community as a potential location for the SKA. Following an introductory description of ASKAP, this document contains 7 chapters describing specific science programmes for ASKAP. The combination of location, technological innovation and scientific program will ensure that ASKAP will be a world-leading radio astronomy facility, closely aligned with the scientific and technical direction of the SKA. A brief summary chapter emphasizes the point, and considers discovery space.

description: The functioning of a living cell is largely determined by the structure of its regulatory network, comprising non-linear interactions between regulatory genes. An important factor for the stability and evolvability of such regulatory systems is neutrality - typically a large number of alternative network structures give rise to the necessary dynamics. Here we study the discretized regulatory dynamics of the yeast cell cycle [Li et al., PNAS, 2004] and the set of networks capable of reproducing it, which we call functional. Among these, the empirical yeast wildtype network is close to optimal with respect to sparse wiring. Under point mutations, which establish or delete single interactions, the neutral space of functional networks is fragmented into 4.7 * 10^8 components. One of the smaller ones contains the wildtype network. On average, functional networks reachable from the wildtype by mutations are sparser, have higher noise resilience and fewer fixed point attractors as compared with networks outside of this wildtype component.

Maximum entropy spectral analysis of free oscillations of the earth : the 1964 Alaska event
Creators: name: Davies, John Charles
Publisher: name: University of British Columbia
Year: 2010

description: The DCLA gravimeter recording obtained after the 1964 Alaska earthquake, has been subjected to various, recently developed data processing techniques. In particular, the maximum entropy method (MEM) of spectral estimation and filter design was utilised. Prediction filters were used to extend the original tidal gravimeter recording, so as to avoid information loss caused by tapering the record prior to filtering. Time adaptive prediction error filters were then used to locate noise bursts, or 'glitches', which are present in the filtered record. The record was then deglitched using two methods, one a predictive approach, and the other involving a division of the record by a weighted envelope function. Power spectra using the classical periodogram approach, as well as MEM, were calculated for the filtered records, both before and after deglitching. This analysis resulted in new values for the splitting parameter 'β', and the centre frequency, for various free oscillation modes. A dramatic increase in the signal to noise ratio was also observed after the filtered records were deglitched. The presence of core mode oscillations was also investigated, but no evidence for these undertones was found. Instead, numerous peaks attributed to either instrument non-linearities, or barometric pressure effects, were found in the frequency range 0.12 to 1.20 cycles per hour.

In particular, for a two--parameter family of two--qutrit states that are part of the magic simplex we calculate the Hilbert--Schmidt measure of entanglement. We present a method to detect bound entanglement which is illustrated for a three--parameter family of states. In this way we discover new regions of bound entangled states. Furthermore we outline how to use our method to distinguish entangled from separable states.

description: We present an exact and Monte Carlo renormalization group (MCRG) study of semiflexible polymer chains on an infinite family of the plane-filling (PF) fractals. The fractals are compact, that is, their fractal dimension $d_f$ is equal to 2 for all members of the fractal family enumerated by the odd integer $b$ ($3\le b< \infty$). For various values of stiffness parameter $s$ of the chain, on the PF fractals (for $3\le b\le 9$) we calculate exactly the critical exponents $ν$ (associated with the mean squared end-to-end distances of polymer chain) and $γ$ (associated with the total number of different polymer chains). In addition, we calculate $ν$ and $γ$ through the MCRG approach for $b$ up to 201. Our results show that, for each particular $b$, critical exponents are stiffness dependent functions, in such a way that the stiffer polymer chains (with smaller values of $s$) display enlarged values of $ν$, and diminished values of $γ$. On the other hand, for any specific $s$, the critical exponent $ν$ monotonically decreases, whereas the critical exponent $γ$ monotonically increases, with the scaling parameter $b$. We reflect on a possible relevance of the criticality of semiflexible polymer chains on the PF family of fractals to the same problem on the regular Euclidean lattices.

title: Die Macht des Autoritären : Herausforderung für demokratische Geschlechterverhältnisse
Creators: name: Wilde, Gabriele
Publisher: name: DuEPublico
Year: 2022

description: Der Wahlsieg der italienischen Neofaschistin Giorgia Meloni, seit 2014 Vorsitzende der rechtsradikalen Partei Fratelli d’Italia, steht für einen weiteren Schritt hin zu einer politischen Entwicklung, die den autoritären Rechtspopulismus als weltweite Regierungsform und weitreichende Regierungsrationalität zu einem sichtbaren Bestandteil politischer Wirklichkeit werden lässt. Weniger offensichtlich sind hingegen die machtvollen Impulse, die das Autoritäre zu einem gesellschaftlichen Ereignis machen und anhand einer Verknüpfung von Narrativen zu Volk, Gender und Migration zur Umgestaltung von demokratischen Geschlechterverhältnissen beitragen.

Wie das Beispiel des Wahlprogramms der Alternative für Deutschland (AfD 2021) zeigt, wirkt eine anwachsende und stetig lauter werdende autoritär-populistische Rechte in öffentlich initiierten Kulturkämpfen auf das Denken und Handeln von Bürger*innen ein. Mit ihren Diskursen zur Familie als „Keimzelle der Gesellschaft“ (AfD 2021, 102) und zum Geschlecht als eine biologische Kategorie greifen sie demokratische Geschlechterverhältnisse an und schaffen durch den Bezug auf das Geschlecht in seiner intersektionalen Verbindung mit weiteren Differenzkategorien wie race, ethnicity und class die Möglichkeit, das Autoritäre als ein neues, geschlechtliches Machtdispositiv in der Gesellschaft zu verankern (Wilde 2021).
The updated BaSTI stellar evolution models and isochrones. III. White Dwarfs

description: We present new cooling models for carbon-oxygen white dwarfs with both H- and He-atmospheres, covering the whole relevant mass range, to extend our updated BaSTI (a Bag of Stellar Tracks and Isochrones) stellar evolution archive. They have been computed using core chemical stratifications obtained from new progenitor calculations, adopting a semiempirical initial-final mass relation. The physics inputs have been updated compared to our previous BaSTI calculations: ^{22}Ne diffusion in the core is now included, together with an updated CO phase diagram, and updated electron conduction opacities. We have calculated models with various different neon abundances in the core, suitable to study white dwarfs in populations with metallicities ranging from super-solar to metal poor, and have performed various tests/comparisons of the chemical stratification and cooling times of our models. Two complete sets of calculations are provided, for two different choices of the electron conduction opacities, to reflect the current uncertainty in the evaluation of the electron thermal conductivity in the transition regime between moderate and strong degeneracy, crucial for the H and He envelopes. We have also made a first, preliminary estimate of the effect -- that turns out to be generally small -- of Fe sedimentation on the cooling times of white dwarf models, following recent calculations of the phase diagrams of carbon-oxygen-iron mixtures. We make publicly available the evolutionary tracks from both sets of calculations, including cooling times and magnitudes in the Johnson-Cousins, Sloan, Pan-STARSS, Galex, Gaia-DR2, Gaia-eDR3, HST-ACS, HST-WFC3, and JWST photometric systems.

description: We consider a large N, two-family Calogero and matrix model in the Hamiltonian, collective-field approach. The Bogomol'nyi limit appears and the solutions to the coupled Bogomol'nyi-Prasad-Sommerfeld equations are given by the static soliton configurations. We find all solutions close to constant and construct exact one-parameter solutions in the strong-weak dual case. Full classification of these solutions is presented.

description: Suzaku observation of an ultraluminous X-ray source, NGC 2403 Source 3, performed on 2006 March 16--17, is reported. The Suzaku XIS spectrum of Source 3 was described with a multi-color black-body-like emission from an optically thick accretion disk. The innermost temperature and radius of the accretion disk was measured to be $T_{\rm in} = 1.08_{-0.03}^{+0.02} $ keV and $R_{\rm in} = 122.1_{-6.8}^{+7.7} α^{1/2}$ km, respectively, where $α= (\cos 60^\circ /\cos i)$ with $i$ being the disk inclination. The bolometric luminosity of the source was estimated to be $L_{\rm bol} = 1.82 \times 10^{39} α$ ergs s$^{-1}$. Archival Chandra and XMM-Newton data of the source were analyzed for long-term spectral variations. In almost all observations, the source showed multi-color black-body-like X-ray spectra with parameters similar to those in the Suzaku observation. In only one Chandra observation, however, Source 3 was found to exhibit a power-law-like spectrum, with a photon index of $Γ= 2.37 \pm 0.08$, when it was fainter by about $\sim 15 %$ than in the Suzaku observation. The spectral behavior is naturally explained in terms of a transition between the slim disk state and the "very high" states, both found in Galactic black hole binaries when their luminosity approach the Eddington limit. These results are utilized to argue that ultraluminous X-ray sources generally have significantly higher black-hole masses than ordinary stellar-mass black holes.

Interactions of keV sterile neutrinos with matter

description: A sterile neutrino with mass of several keV is a well-motivated dark-matter candidate, and it can also explain the observed velocities of pulsars via anisotropic emission of sterile neutrinos from a cooling neutron star. We discuss the interactions of such relic particles with matter and comment on the prospects of future direct detection experiments. A relic sterile neutrino can interact, via sterile-active mixing, with matter fermions by means of electroweak currents, with the final state containing a relativistic active neutrino. The recoil momentum impacted onto a matter fermion is determined by the sterile neutrino mass and is enough to ionize atoms and flip the spins of nuclei. While this suggests a possibility of direct experimental detection, we calculate the rates and show that building a realistic detector of the required size would be a daunting challenge.
