description: Neutron stars were first posited in the early thirties, and discovered as pulsars in late sixties; however, only recently are we beginning to understand the matter they contain. This talk describes the continuing development of a consistent picture of the liquid interiors of neutron stars, driven by four advances: observations of two heavy neutron stars with masses $\simeq$ 2.0 solar masses; inferences of masses and radii simultaneously for an increasing number of neutron stars in low mass X-ray binaries, and future determinations via the NICER observatory; the observation of the binary neutron star merger, GW170817, through gravitational waves as well as across the electromagnetic spectrum; and an emerging understanding in QCD of how nuclear matter can turn into deconfined quark matter in the interior. We describe the modern quark-hadron crossover equation of state, QHC18, and the corresponding neutron stars, which agree well with current observations.

description: We show that homogeneous Gödel spacetimes need not contain closed timelike curves in low-energy-effective string theories. We find exact solutions for the Gödel metric in string theory for the full $O(α^{\prime})$ action including both dilaton and axion fields. The results are valid for bosonic, heterotic and super-strings. To first order in the inverse string tension $α^{\prime}$, these solutions display a simple relation between the angular velocity of the Gödel universe, $Ω,$ and the inverse string tension of the form $α^{\prime}=1/Ω^2$ in the absence of the axion field. The generalization of this relationship is also found when the axion field is present.

description: The overall objective of 'social' dialogue systems is to support engaging, entertaining, and lengthy conversations on a wide variety of topics, including social chit-chat. Apart from raw dialogue data, user-provided ratings are the most common signal used to train such systems to produce engaging responses. In this paper we show that social dialogue systems can be trained effectively from raw unannotated data. Using a dataset of real conversations collected in the 2017 Alexa Prize challenge, we developed a neural ranker for selecting 'good' system responses to user utterances, i.e. responses which are likely to lead to long and engaging conversations. We show that (1) our neural ranker consistently outperforms several strong baselines when trained to optimise for user ratings; (2) when trained on larger amounts of data and only using conversation length as the objective, the ranker performs better than the one trained using ratings -- ultimately reaching a Precision@1 of 0.87. This advance will make data collection for social conversational agents simpler and less expensive in the future.

title: The caregiver experience of family members of people with persistent psychosis and negative symptoms: An exploratory mixed method analysis of metacognition, caregiver attributions, emotional over-involvement and distress
Creators: name: Homes, Amy
Publisher: name: University of Glasgow
Year: 2019
Subjects: subject: psychosis, metacognition, caregivers, negative symptoms.

description: Many relatives caring for someone experiencing psychosis, display high levels of psychological distress. This can result in poorer mental health for both the carer and patient. Negative symptoms have been shown to especially hamper recovery, although little is known about their development and maintenance. Jansen et al. (2014) found greater metacognitive ability in the caregiver can improve coping and reduce distress in caregivers of those with FEP. This study explores the relationship between caregiver experience and metacognitive ability in those with multi-episodic persistent psychosis, exploring if caregivers with greater metacognitive ability have reduced levels of distress and whether there are indicators that negative symptoms are developed and maintained in a relational context.

description: Background: The anti–interleukin-6 receptor antibody tocilizumab is approved for subcutaneous injection using a prefilled syringe (PFS). We report results from a bioequivalence study in healthy subjects and a user-handling study in patients with rheumatoid arthritis (RA) using an autoinjector (AI) for tocilizumab. Methods: A randomized crossover study in healthy subjects (N = 161) examined the bioequivalence, safety, and tolerability of tocilizumab after a single subcutaneous injection by AI versus PFS. A nonrandomized observational, real-life human factors study in RA patients (N = 54) assessed user (RA patients, caregivers, health care providers) ability to administer tocilizumab effectively by AI. Results: Bioequivalence criteria for tocilizumab AI versus PFS were met for key pharmacokinetic parameters. Safety was comparable between devices and consistent with the established tocilizumab profile. In the real-life human factors study, the proportion of users who successfully performed all essential tasks required to operate the AI to deliver the full dose was 92.3% at first assessment and 98.1% at second assessment, with no safety concerns. Conclusions: Tocilizumab administration by AI was bioequivalent to administration by PFS. Intended users were successful in performing the tasks required to administer tocilizumab by AI. No new safety signals were observed in either study. Clinical Trial Registration: NCT02678988, NCT02682823

description: This paper investigates water sorption and dehydration of a model synthetic clay (Laponite) and highlights the large differences with natural clays (montmorillonite, hectorite) belonging to smectite family of structure and composition. Measurements were done by combining for the first time thermogravimetric analysis and X Ray diffraction methods on Laponite powders stored in atmospheres with controlled relative humidity. Laponite exhibits a very good reproducibility of sorption diagram and appears as the most hygroscopic among smectites. The interlayer space increases from 11 to 20 Angstrom when r = n H2O /n Na increases from 2 to 22 in agreement with recent numeric simulations by Morrow et al. We show that the desorption process, for 2 < r < 22, in isothermal conditions follow a first order kinetic identifying two regimes around r* = 7 which is close to the coordination number of Na in concentrated NaCl solution. Activation energies and frequency factors are derived for the two regimes of water desorption and discussed in relation with stability of the cationic complex.
title: Habits of the heart: a sketch of a Bourdieusian theory of study selection using the example of German economics students
Creators: name: Winzler, Tim
Publisher: name: University of Glasgow
Year: 2019
Subjects: subject: Sociology of Knowledge, sociology of education, sociology of science, study choice, Bourdieu.

description: The project aims to explore the relationship between social origin, habitus and study selection of successful German Economics students in order to better understand the disciplinary reproduction of academic Economics as well as its current state. It uses Pierre Bourdieu’s field theory, as applied to the areas of education and science, to develop a sketch of a theory of study selection that mirrors the relational, structural and analogical character of this particular viewpoint. In this, the work differs from the rather substantialist and subjectivist literature on the topic to be found in contemporary British and German Social Science. It questions common sense assumptions about study choice such as the concepts of an ‘intrinsic’ or ‘extrinsic’ motivation, as well as an easily distinguishable ‘reflexivity’ of structures on the part of agents. Indeed, it questions the very concept of study ‘choice’ in favour of a more relational approach. Combining in-depth interviews with successful and interested (‘recognised’) German Economics students about their educational trajectory and study selections with socio-demographic descriptive statistics, the project attempts in essence to suggest a theoretical sociological interpretation concerning the ‘subjective’ viewpoint of the specific groups that make up this rather extraordinary group. To this end, it formulates three ideal-typical models that each link social origin, habitus and study selection differently. The Inheritors, coming from a ‘cadre’ origin, tend to favour technical-mathematical thinking while at the same time rejecting more ‘literal’ approaches, both of which attract them to Economics and its orthodox thinking. The Fallen Nobles, who come from more bourgeois backgrounds which have however lost parts of their capital, are geared towards symbolic ostentation and partial revolution, which in academic Economics tends to be bound up, at least at the moment, with ultraliberal positions. Finally, the Parvenus, coming from more petit-bourgeois backgrounds, tend to have a very faithful, that is, indulgent and docile relationship to their chosen ethical-academic framework which varies considerably even within Economics. They end up with rather technical specialisations. In summary, it is suggested that the study selection of a group of students who are all ‘intrinsically’ motivated can in fact be attributed to quite different sociological processes and relations. This opens up new ways and fresh empirical questions to view and assess study selection.
A STUDY ON THE ASSOCIATION BETWEEN 25(OH) VITAMIN D AND GLYCOSYLATED HEMOGLOBIN (HbA1c) LEVEL IN TYPE II DIABETIC PATIENTS ATTENDING A TERTIARY CARE HOSPITAL IN WESTERN UTTAR PRADESH

description: Abstract

Background:  Diabetes is a serious health condition that poses significant challenges to development, particularly in the context of modern lifestyle changes and urbanization, which greatly elevate an individual's risk of developing the disease. In recent years, there has been growing interest in Vitamin D, often referred  to as the "Sunshine Vitamin," due to its potential links to various health issues, including hypertension, cardiovascular diseases, diabetes, and cancer. A substantial body of research suggests that a deficiency in Vitamin D may play a crucial role in the development of micro & macrovascular complications of Type 2 diabetes. Material & Methods: A total of 110 subjects of diagnosed Type II diabetes mellitus in the age group of 20 to 70 years not on vitamin D supplements were included in this study. Subjects with chronic kidney & liver diseases and pregnant women were excluded. Result: There was negative non-significant correlation between the serum level of Vitamin D and HbA1c level in these subjects. Conclusion: Monitoring the serum level of vitamin D in diabetic patients and providing supplements if necessary would be useful, as vitamin D is essential for the human body and helpful in preventing the complications of diabetes mellitus. Longitudinal studies with larger population size may help in addressing the correlation and mechanism of association between Vitamin D levels & HbA1c in Type 2 DM.

description: We have measured the electric transport properties of TiN nanostrips with different widths. At zero magnetic field, the temperature-dependent resistance R(T) saturates at a finite resistance toward low temperatures, which results from quantum phase slips in the narrower strips. We find that the current-voltage (I−V) characteristics of the narrowest strips are equivalent to those of small Josephson junctions. Applying a transverse magnetic field drives the devices into a reentrant insulating phase, with I−V characteristics dual to those in the superconducting regime. The results provide evidence that our critically disordered superconducting nanostrips behave like small self-organized random Josephson networks.

description: We introduce the pseudohole and heavy-pseudoparticle operator algebra that generates all Hubbard-chain eigenstates from a single reference vacuum. In addition to the pseudoholes already introduced for the description of the low-energy physics, this involves the heavy pseudoparticles associated with Hamiltonian eigenstates whose energy spectrum has a gap relatively to the many-electron ground state. We introduce a generalized pseudoparticle perturbation theory which describes the relevant finite-energy ground state transitions. In the present basis these excitations refer to a small density of excited pseudoparticles. Our operator basis goes beyond the Bethe-ansatz solution and it is the suitable and correct starting point for the study of the finite-frequency properties, which are of great relevance for the understanding of the unusual spectral properties detected in low-dimensional novel materials.

description: On simply connected five manifolds Sasakian-Einstein metrics coincide with Riemannian metrics admitting real Killing spinors which are of great interest as models of near horizon geometry for three-brane solutions in superstring theory [KW]. We expand on the recent work of Demailly and Kollár [DK] and Johnson and Kollár [JK1] who give methods for constructing Kähler-Einstein metrics on log del Pezzo surfaces. By [BG1] circle V-bundles over log del Pezzo surfaces with Kähler-Einstein metrics have Sasakian-Einstein metrics on the total space of the bundle. Here these simply connected 5-manifolds arise as links of isolated hypersurface singularities which by the well known work of Smale [Sm] together with [BG3] must be diffeomorphic to $\scriptstyle{S^5#l(S^2\times S^3)}.$ More precisely, using methods from Mori theory in algebraic geometry we prove the existence of 14 inequivalent Sasakian-Einstein structures on $\scriptstyle{S^2\times S^3}$ and infinite families of such structures on $\scriptstyle{#l(S^2\times S^3)}$ with $\scriptstyle{2\leq l\leq7}$. We also discuss the moduli problem for these Sasakian-Einstein structures.

title: Almost finiteness of groupoid actions and Z-stability of C*-algebras associated to tilings
Creators: name: Ito, Luke John
Publisher: name: University of Glasgow
Year: 2019
Subjects: subject: Tilings, C*-algebras, classification, Z-stability, groupoids, almost finiteness, quasidiagonality.

description: The property of almost finiteness was first introduced by Matui for locally compact Hausdorff totally disconnected étale groupoids with compact unit spaces, and has since been extended by Suzuki to drop the assumption of being totally disconnected. A property of the same name has been defined by Kerr for free actions of discrete groups on compact metric spaces. In this setting, Kerr shows that almost finiteness has direct relevance to the classification programme for simple, separable, unital, nuclear, infinite dimensional C*-algebras, as it implies that the associated crossed product is Z-stable. The motivating example for this thesis comes from the theory of aperiodic tilings. A tiling is a covering of Euclidean space by a collection of sets (called tiles) which overlap only on their boundaries. A tiling is called aperiodic if it does not contain arbitrarily large periodic patterns. Such tilings find physical applications, acting as models for quasicrystals. One may associate a groupoid to certain aperiodic tilings, and the C*-algebras of such groupoids encode information about physical observables in quasicrystalline molecules. In this thesis, we generalise Kerr's notion of almost finiteness of group actions to allow for actions of groupoids. We show that the canonical action of the groupoid associated to any aperiodic, repetitive tiling with finite local complexity on its unit space is almost finite, and we use this to show that the C*-algebra of the tiling is Z-stable. We develop a groupoid version of the Ornstein-Weiss quasitiling machinery, which we use to prove our Z-stability result. Finally, we give a direct proof that tiling C*-algebras are quasidiagonal, which eases the route to classification in the case that the algebra has unique trace.
Axial quasi-normal modes of scalarized neutron stars with massive self-interacting scalar field

description: We study the axial quasi-normal modes of neutron stars in scalar-tensor theories with massive scalar field including a self-interacting term in the potential. Various realistic equations of state including nuclear, hyperonic and hybrid matter are employed. Although the effect of spontaneous scalarization of neutron stars can be very large, binary pulsar observations and gravitational wave detections significantly constrain the massless scalar-tensor theories. If we consider a properly chosen nonzero mass for the scalar field, though, the scalar-tensor parameters cannot be restricted by the observations, resulting in large deviation from pure general relativity. With this motivation in mind, we extend the universal relations for axial quasi-normal modes known in general relativity to neutron stars in massive scalar-tensor theories with self-interaction using a wide range of realistic EOS. We confirm the universality of the scaled frequency and damping time in terms of the compactness and scaled moment of inertia for neutron stars with and without massive scalarization.

This report is part of a European Union funded project, namely, “Fostering food system transformation by integrating heterogeneous perspectives in knowledge and innovation within the ERA” (FOSTER, Grant Agreement No. 101059954). The FOSTER project aims to contribute to changing the scientific knowledge base and the associated knowledge and innovation system in support of food system transformation towards sustainability. To this end, the FOSTER project collaborates closely with six change-driven initiatives (CDIs) from across the food systems, which are based in five countries across Europe: Fab Lab Barcelona as part of the Institute for Advanced Architecture of Catalonia (Fab Lab IAAC - Spain), Living Lab for Health - as part of the Research Institute IrsiCaixa (Living Lab IrsiCaixa - Spain), the Food Policy Council Stuttgart (ERS - Germany), Delta Foundation (DELTA - Serbia) with the local initiative called “Digital Village,” Pannonian Local Products Nonprofit Ltd. (PLP - Hungary), and the Food Transition Coalition (TcV – the Netherlands).The aim of this report is to provide a baseline assessment for these CDIs, by sharing insights from each CDI with respect to their ambitions, their theories of change, and their activities. Additionally, the CDIs’ target stakeholder groups and interactions with the Knowledge & Innovation system are examined. In order to answer the objectives of the report, several data sources have been drawn upon, including notes from the project kick-off meeting, and results of a survey initiated by the University of Hohenheim and the University of Oxford. Additionally, focus group discussion sessions between academic partners (APs) and CDIs, as well as additional interactions via semi-structured interviews and follow-up correspondence with the CDIs are used as data sources for this report.

description: Shot noise in diffusive mesoscopic conductors, at finite observation frequencies $ω$ (comparable to the reciprocal Thouless time $τ_T^{-1}$), is analyzed with an account of screening. At low frequencies, the well-known result $S_I(ω)=2eI/3$ is recovered. This result is valid at arbitrary $ωτ_T$ for wide conductors longer than the screening length. However, at least for two very different systems, namely, wide and short conductors, and thin conductors over a close ground plane, noise approaches a different fundamental level, $S_I(ω) = eI$, at $ωτ_T\gg 1$.

description: Phase response curve is an important tool in studies of stable self-sustained oscillations; it describes a phase shift under action of an external perturbation. We consider multistable oscillators with several stable limit cycles. Under a perturbation, transitions from one oscillating mode to another one may occur. We define phase transfer curves to describe the phase shifts at such transitions. This allows for a construction of one-dimensional maps that characterize periodically kicked multistable oscillators. We show, that these maps are good approximations of the full dynamics for large periods of forcing.

description: Power-law sensitivity to initial conditions, characterizing the behaviour of dynamical systems at their critical points (where the standard Liapunov exponent vanishes), is studied in connection with the family of nonlinear 1D logistic-like maps $x_{t+1} = 1 - a | x_t |^z, (z > 1; 0 < a \le 2; t=0,1,2,...)$ The main ingredient of our approach is the generalized deviation law $\lim_{Δx(0) -> 0} Δx(t) / Δx(0)} = [1+(1-q)λ_q t]^{1/(1-q)}$ (equal to $e^{λ_1 t}$ for q=1, and proportional, for large t, to $t^{1/(1-q)}$ for $q \ne 1; q \in R$ is the entropic index appearing in the recently introduced nonextensive generalized statistics). The relation between the parameter q and the fractal dimension d_f of the onset-to-chaos attractor is revealed: q appears to monotonically decrease from 1 (Boltzmann-Gibbs, extensive, limit) to -infinity when d_f varies from 1 (nonfractal, ergodic-like, limit) to zero.

It is found that a reasonable description can be given assuming a spatial electron density profile corresponding to a finite width of the shock wave front of about $2 10^-6 m.

description: Measles, an acute viral disease, continues to be an important cause of childhood mortality worldwide. Infection with the measles virus is thought to be associated with a transient but profound period of immune suppression. Recently, it has been claimed that measles-induced immune manipulation lasts for about 30 months and results in increased susceptibility to other co-circulating infectious diseases and more severe disease outcomes upon infection. We tested this hypothesis using model-based inference applied to parallel historical records of measles and whooping cough mortality and morbidity. Specifically, we used maximum likelihood to fit a mechanistic transmission model to incidence data from three different eras, spanning mortality records from 1904 to 1912 and 1922 to 1932 and morbidity records from 1946 to 1956. Our aim was to quantify the timing, severity and pathogenesis impacts of measles-induced immune modulation and their consequences for whooping cough epidemiology across a temporal gradient of measles transmission. We identified an increase in susceptibility to whooping cough following recent measles infection by approximately 85-, 10- and 36-fold for the three eras, respectively, although the duration of this effect was variable. Overall, while the immune impacts of measles may be strong and clearly evident at the individual level, their epidemiological signature in these data appears both modest and inconsistent.This article is part of the theme issue ‘Detection, forecasting and control of infectious disease epidemics: modelling outbreaks in humans, animals and plants Part 1’.

description: Singular spacetimes are a natural prediction of Einstein's theory. Most memorable are the singular centers of black holes and the big bang. However, dilatonic extensions of Einstein's theory can support nonsingular spacetimes. The cosmological singularities can be avoided by dilaton driven inflation. Furthermore, a nonsingular black hole can be constructed in two dimensions.

description: On the basis of Quantum Monte Carlo simulations of the two-dimensional Hubbard model which cover the doping range from the under- to the over-doped regime, we find that the single-particle spectral weight $A (\vec k,ω)$ qualitatively reproduces both the momentum ($d_{x^2-y^2}$--symmetry) and doping dependence of the pseudogap as found in photoemission experiments. The drastic doping dependence of the spin response $χ_{s} (\vec q,ω)$ which is sharp in both $\vec q (\approx(π,π))$ and $ω$ in the under-doped regime but broad and structureless otherwise, identifies remnants of the antiferromagnetic order as the driving mechanism behind the pseudogap and its evolution with doping.

The Object Coordination Class Applied to Wavepulses: Analysing Student Reasoning in Wave Physics
Creators: name: Wittmann, Michael C.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Physics Education (physics.ed-ph)
subject: FOS: Physical sciences

description: Detailed investigations of student reasoning show that students approach the topic of wave physics using both event-like and object-like descriptions of wavepulses, but primarily focus on object properties in their reasoning. Student responses to interview and written questions are analysed using diSessa and Sherin's coordination class model which suggests that student use of specific reasoning resources is guided by possibly unconscious cues. Here, the term reasoning resources is used in a general fashion to describe any of the smaller grain size models of reasoning (p-prims, facets of knowledge, intuitive rules, etc) rather than theoretically ambiguous (mis)conceptions. Student applications of reasoning resources, including one previously undocumented, are described. Though the coordination class model is extremely helpful in organising the research data, problematic aspects of the model are also discussed.

Gravitational Radiation Instability in Hot Young Neutron Stars

description: We show that gravitational radiation drives an instability in hot young rapidly rotating neutron stars. This instability occurs primarily in the l=2 r-mode and will carry away most of the angular momentum of a rapidly rotating star by gravitational radiation. On the timescale needed to cool a young neutron star to about T=10^9 K (about one year) this instability can reduce the rotation rate of a rapidly rotating star to about 0.076Ω_K, where Ω_K is the Keplerian angular velocity where mass shedding occurs. In older colder neutron stars this instability is suppressed by viscous effects, allowing older stars to be spun up by accretion to larger angular velocities.

Pickering emulsions with alpha-cyclodextrin inclusions: Structure and thermal stability

description: This paper explores structural, interfacial and thermal properties of two types of Pickering emulsions containing alpha-cyclodextrin inclusion complexes: on one hand, emulsions were obtained between aqueous solutions of alpha-cyclodextrin and different oils (fatty acids, olive oil, silicone oil) and on the other hand, emulsions were obtained between these oils, water and micro or nano-platelet suspensions with inclusion complexes of hydrophobically-modified polysaccharides. The emulsions exhibit versatile properties according to the molecular architecture of the oils. Experiments were performed by microcalorimetry, X-ray diffraction and confocal microscopy. The aptitude of oil molecules to be threaded in alpha-cyclodextrin cavity is a determining parameter in emulsification and thermal stability. The heat flow traces and images showed dissolution, cooperative melting and de- threading of inclusion complexes which take place progressively, ending at high temperatures, close or above 100°C. Another important feature observed in the emulsions with micro-platelets is the partial substitution of the guest molecules occurring at room temperature at the oil/water interfaces without dissolution, possibly by a diffusion mechanism of the oil. Accordingly, the dissolution and the cooperative melting temperatures of the inclusion crystals changed, showing marked differences upon the type of guest molecules. The enthalpies of dissolution of crystals were measured and compared with soluble inclusions.
Prediction for the singlet-triplet excitation energy for the spinel MgTi$_2$O$_4$ using first-principles diffusion Monte Carlo

description: The spinel, MgTi$_2$O$_4$, undergoes a transition into a dimerized state at low temperatures that is expected to be a spin singlet. However, no signature of a singlet-triplet transition has been discovered, in part due to the difficulty of predicting the energy of the transition from theory. We find that the dimers of MgTi$_2$O$_4$ can be described by a Heisenberg model with very small interactions between different dimers. Using high-accuracy first-principles quantum Monte Carlo combined with a novel model-fitting approach, we predict the singlet-triplet gap of these dimers to be 350(50) meV, a higher energy than previous experimental observations have considered. The prediction is published in advance of experimental confirmation.

description: Cyclodextrins are a family of oligosaccharides with a toroid shape which exhibit a unique ability of entrapping guest molecules in their internal cavity. Water is the primary guest molecule and is omnipresent in the crystalline phases stabilizing the overall architecture. Despite the presence of water molecules inside the cavity, cyclodextrins provide a hydrophobic environment where poorly soluble molecules can easily fit. In this investigation we put in evidence different types of water in the hydrated α , \b{eta} and γ cyclodextrin crystals. Thermogravimetric measurements identify various binding sites of water and highlight the difference between the crystals equilibrated under various humid atmospheres. We establish by microcalorimetry the limit of solubility versus temperature and measure for the first time the melting temperatures of the hydrated crystals. Dissolution and melting enthalpies are derived and the solubility curves are compared to existing literature. The specific features of each cyclodextrin are underlined.

Self-assembly of model proteins into virus capsids

Publisher: name: arXiv
Year: 2018
Subjects: subject: Biomolecules (q-bio.BM)
subject: FOS: Biological sciences

description: We consider self-assembly of proteins into a virus capsid by the methods of molecular dynamics. The capsid corresponds either to SPMV or CCMV and is studied with and without the RNA molecule inside. The proteins are flexible and described by the structure-based coarse-grained model augmented by electrostatic interactions. Previous studies of the capsid self-assembly involved solid objects of a supramolecular scale, e.g. corresponding to capsomeres, with engineered couplings and stochastic movements. In our approach, a single capsid is dissociated by an application of a high temperature for a variable period and then the system is cooled down to allow for self-assembly. The restoration of the capsid proceeds to various extent, depending on the nature of the dissociated state, but is rarely complete because some proteins depart too far unless the process takes place in a confined space.
