description: We present a new environment for computations in particle physics phenomenology employing recent developments in cloud computing. On this environment users can create and manage "virtual" machines on which the phenomenology codes/tools can be deployed easily in an automated way. We analyze the performance of this environment based on "virtual" machines versus the utilization of "real" physical hardware. In this way we provide a qualitative result for the influence of the host operating system on the performance of a representative set of applications for phenomenology calculations.

Electromagnetic Media with no Dispersion Equation

subject: FOS: Physical sciences

description: It has been known through some examples that parameters of an electromagnetic medium can be so defined that there is no dispersion equation (Fresnel equation) to restrict the choice of the wave vector of a plane wave in such a medium, i.e., that the dispersion equation is satisfied identically for any wave vector. In the present paper, a more systematic study to define classes of media with no dispersion equation is attempted. The analysis makes use of coordinate-free four-dimensional formalism in terms of multivectors, multiforms and dyadics.

description: Three dimensional molecular dynamics (MD) is used to model the mechanical
response at the interface between a thin Cu coating resting on a base of Si. The copper coating
is subjected to a displacement controlled shear load and the atom movements at the Si-Cu
interface are monitored to investigate the effects of crystallographic anisotropy. The two
crystals have the same crystallographic orientation, and two different interface normal
directions are considered. The shear load is applied along different crystallographic directions
to highlight the importance of crystallographic orientation for the mechanical response. The
simulations are performed with the 3D MD free-ware LAMMPS. As the imposed
displacement reaches a high enough magnitude, the Cu coating starts to slide over the Si base.
Thus the atoms at the interface rearrange depending on loading direction and crystallographic
orientation.

description: The question of the existence of a spin liquid state in the half-filled Hubbard model on the honeycomb (aka graphene) lattice is revisited. The Variational Cluster Approximation (VCA), the Cluster Dynamical Mean Field Theory (CDMFT) and the Cluster Dynamical Impurity Approximation (CDIA) are applied to various cluster systems. Assuming that the spin liquid phase coincides with the Mott insulating phase in this non-frustrated system, we find that the Mott transition is pre-empted by a magnetic transition occuring at a lower value of the interaction $U$, and therefore the spin liquid phase does not occur. This conclusion is obtained using clusters with two bath orbitals connected to each boundary cluster site. We argue that using a single bath orbital per boundary site is insufficient and leads to the erroneous conclusion that the system is gapped for all nonzero values of $U$.

description: During neuroinflammation, monocytes that infiltrate the central nervous system (CNS) may contribute to regenerative processes depending on their activation status. However, the extent and mechanisms of monocyte-induced CNS repair in patients with neuroinflammatory diseases remain largely unknown, partly due to the lack of a fully human assay platform that can recapitulate monocyte-neural stem cell interactions within the CNS microenvironment. We therefore developed a human model system to assess the impact of monocytic factors on neural stem cells, establishing a high-content compatible assay for screening monocyte-induced neural stem cell proliferation and differentiation. The model combined monocytes isolated from healthy donors and human embryonic stem cell derived neural stem cells and integrated both cell-intrinsic and -extrinsic properties. We identified CNS-mimicking culture media options that induced a monocytic phenotype resembling CNS infiltrating monocytes, while allowing adequate monocyte survival. Monocyte-induced proliferation, gliogenic fate and neurogenic fate of neural stem cells were affected by the conditions of monocytic priming and basal neural stem cell culture as extrinsic factors as well as the neural stem cell passage number as an intrinsic neural stem cell property. We developed a high-content compatible human in vitro assay for the integrated analysis of monocyte-derived factors on CNS repair.

description: We discuss some of the analytic properties of lens space indices for 4d N=2 theories of class S. The S-duality properties of these theories highly constrain the lens space indices, and imply in particular that they are naturally acted upon by a set of commuting difference operators corresponding to surface defects. We explicitly identify the difference operators to be a matrix-valued generalization of the elliptic Ruijsenaars-Schneider model. In a special limit these difference operators can be expressed naturally in terms of Cherednik operators appearing in the double affine Hecke algebras, with the eigenfunctions given by non-symmetric Macdonald polynomials.

Convexity and quasi-uniformizability of closed preordered spaces

description: In many applications it is important to establish if a given topological preordered space has a topology and a preorder which can be recovered from the set of continuous isotone functions. Under antisymmetry this property, also known as quasi-uniformizability, allows one to compactify the topological space and to extend its order dynamics. In this work we study locally compact $σ$-compact spaces endowed with a closed preorder. They are known to be normally preordered, and it is proved here that if they are locally convex, then they are convex, in the sense that the upper and lower topologies generate the topology. As a consequence, under local convexity they are quasi-uniformizable. The problem of establishing local convexity under antisymmetry is studied. It is proved that local convexity holds provided the convex hull of any compact set is compact. Furthermore, it is proved that local convexity holds whenever the preorder is compactly generated, a case which includes most examples of interest, including preorders determined by cone structures over differentiable manifolds. The work ends with some results on the problem of quasi-pseudo-metrizability. As an application, it is shown that every stably causal spacetime is quasi-uniformizable and every globally hyperbolic spacetime is strictly quasi-pseudo-metrizable.

On the Reflection Type Decomposition of the Adjoint Reduced Phase Space of a Compact Semisimple Lie group

Publisher: name: arXiv

Subjects: subject: Mathematical Physics (math-ph)

description: We consider a system with symmetries whose configuration space is a compact Lie group, acted upon by inner automorphisms. The classical reduced phase space of this system decomposes into connected components of orbit type subsets. To investigate hypothetical quantum effects of this decomposition one has to construct the associated costratification of the Hilbert space of the quantum system in the sense of Huebschmann. In the present paper, instead of the decomposition by orbit types, we consider the related decomposition by reflection types (conjugacy classes of reflection subgroups). These two decompositions turn out to coincide e.g. for the classical groups SU(n) and Sp(n). We derive defining relations for reflection type subsets in terms of irreducible characters and discuss how to obtain from that the corresponding costratification of the Hilbert space of the system. To illustrate the method, we give explicit results for some low rank classical groups.

title: Children and young people’s experiences of growing up with cerebral palsy in rehabilitation
Creators: name: Young, Colin
Publisher: name: University of Glasgow
Year: 2023

description: This thesis explores the relationship between children and young people with Cerebral Palsy’s experience of rehabilitation and its impact on their psychoemotional development and sense of self. This thesis identifies that there has been a lack of discussion regarding the impact of undertaking rehabilitation and developing a sense of self as a person with Cerebral Palsy. By conducting semistructured interviews with 16 children and young people who identified as having Cerebral Palsy about their experience of the rehabilitative process, this research makes three main findings; rehabilitation contributed to participants’ psychoemotional response to their walking ability; rehabilitation constructed a version of independence, which impacted participants’ sense of self when the reality differed from their expectation; and, due to their lack of agency in the process, rehabilitation led to participants experiencing internalised oppression based on a belief that they had to improve their functionality through therapy. Based on these findings, this thesis makes a recommendation for further research into people with Cerebral Palsy’s experiences of pain and degeneration, and a policy proposal that rehabilitation services should take a lifelong approach to enhance the physical, social, and psycho-emotional well-being of children, young people, and adults with Cerebral Palsy.

[[worker]] media et minor. Longueur 5,5 à 6,5 mill. Cette forme est fort embarrassante. Elle se distingue des petits exemplaires du C. dromedarius par son thorax beaucoup moins voûté et par sa tête non comprimée sur les cotés, c'est-à-dire par le même caractère que le C. Christi. Sa couleur est très rapprochée de celle du C. Christi, race Foersteri. Mais lorsqu'on l'examine avec soin, on trouve des différences de forme qui font hésiter.
La tête est plus courte, plus triangulaire, plus élargie derrière que chez le C. Foersteri œ sans les mandibules) et large de 1,75 mill. Ceci est d'autant plus important qu'il s'agit d'une [[worker]] media, tandis que, même chez la [[worker]] major du C. Foersteri œ est plus longue que large. En outre, le thorax est inoins convexe; l'écaillé moins épaisse, rétrécie devant, notablement plus large qu'épaisse chez la [[worker]] minor; la sculpture un peu plus forte, ce qui rend le devant de la tête un peu subopaque. La tête de la [[worker]] minor est encore élargie derrière, ce qui n'est pas le cas chez le C. Foersteri œ sont un peu plus courtes et moins courbées. D'un autre côté, l'écaillé bien plus épaisse, le thorax un peu plus convexe et le métanotum non concave distinguent cette forme du C. quadrimaculatus, sans parler de la couleur.
Pilosité, sculpture et pubescence du reste identiques à celles du C. Christi.
Noir, luisant. Une partie des hanches, des anneaux fémoraux, des cuisses et des tibias, vers l'extrémité, ainsi que la base des scapes, d'un jaune testacé. Mandibules d'un brun foncé, ainsi que le reste des pattes et des antennes.
Dans la clef analytique, cette espèce doit être placée au chiffre 5, à côté du C. Christi, lors même que ses caractères ne l'y font pas absolument rentrer, car l'écaillé de la [[worker]] minor n'est pas tout à fait cubique et le thorax est moins voûté.
Faut-il en faire une simple race du C. Christi? C'est ce que l'avenir montrera.

description: We shall first study summability of families in normed spaces indexed with well ordered sets of real numbers extended by infinity. Obtained results and a generalized iteration method are applied to derive necessary and sufficient conditions for HK, HL, Bochner and Riemann integrability of step mappings and for right regulated mappings from an interval of reals extended by infinity to a Banach space. Finally, solvability of impulsive differential equations are studied.

description: Collecting experimental insight into the relativistic particle populations and emission mechanisms at work within TeV-emitting blazar jets, which are spatially unresolvable in most bands and have strong beaming factors, is a daunting task. New observational information has the potential to lead to major strides in understanding the acceleration site parameters. Detection of molecular carbon monoxide (CO) in TeV emitting blazars, however, implies the existence of intrinsic gas, a connection often found in photo-dissociated region models and numerical simulations. The existence of intrinsic gas within a blazar could provide a target photon field for Compton up-scattering of photons to TeV energies by relativistic particles. We investigate the possible existence of intrinsic gas within the three TeV emitting blazars RGB J0710+591, W Comae and 1ES 1959+650 which have measurements or upper limits on molecular CO line luminosity using an independent technique which is based on the spectral analysis of soft X-rays. Evidence for X-ray absorption by additional gas beyond that measured within the Milky Way is searched for in Swift X-ray Telescope (XRT) data between 0.3 and 10 keV. Without complementary information from another measurement, additional absorption could be misinterpreted as an intrinsically curved X-ray spectrum since both models can frequently fit the soft X-ray data. After breaking this degeneracy, we do not find evidence for intrinsically curved spectra for any of the three blazars. Moreover, no evidence for intrinsic gas is evident for RGB J0710+591 and W Comae, while the 1ES 1959+650 XRT data support the existence of intrinsic gas with a column density of $\sim1\times10^{21}$cm$^{-2}$.

description: We describe in detail the implementation of a simplified approach to radiative transfer in general relativity by means of the well-known neutrino leakage scheme (NLS). In particular, we carry out an extensive investigation of the properties and limitations of the NLS for isolated relativistic stars to a level of detail that has not been discussed before in a general-relativistic context. Although the numerous tests considered here are rather idealized, they provide a well-controlled environment in which to understand the relationship between the matter dynamics and the neutrino emission, which is important in order to model the neutrino signals from more complicated scenarios, such as binary neutron-star mergers. When considering nonrotating hot neutron stars we confirm earlier results of one-dimensional simulations, but also present novel results about the equilibrium properties and on how the cooling affects the stability of these configurations. In our idealized but controlled setup, we can then show that deviations from the thermal and weak-interaction equilibrium affect the stability of these models to radial perturbations, leading models that are stable in the absence of radiative losses, to a gravitational collapse to a black hole when neutrinos are instead radiated.

description: The clinical course of COVID-19 is variable and often unpredictable. To test the hypothesis that disease progression and inflammatory responses associate with alterations in the microbiome and metabolome, we analyzed metagenome, metabolome, cytokine, and transcriptome profiles of repeated samples from hospitalized COVID-19 patients and uninfected controls, and leveraged clinical information and post-hoc confounder analysis. Severe COVID-19 was associated with a depletion of beneficial intestinal microbes, whereas oropharyngeal microbiota disturbance was mainly linked to antibiotic use. COVID-19 severity was also associated with enhanced plasma concentrations of kynurenine and reduced levels of several other tryptophan metabolites, lysophosphatidylcholines, and secondary bile acids. Moreover, reduced concentrations of various tryptophan metabolites were associated with depletion of Faecalibacterium , and tryptophan decrease and kynurenine increase were linked to enhanced production of inflammatory cytokines. Collectively, our study identifies correlated microbiome and metabolome alterations as a potential contributor to inflammatory dysregulation in severe COVID-19.

description: Recent research shows that videogame training enhances neuronal plasticity and cognitive improvements in healthy individuals. As patients with schizophrenia exhibit reduced neuronal plasticity linked to cognitive deficits and symptoms, we investigated whether videogame-related cognitive improvements and plasticity changes extend to this population. In a training study, patients with schizophrenia and healthy controls were randomly assigned to 3D or 2D platformer videogame training or E-book reading (active control) for 8 weeks, 30 min daily. After training, both videogame conditions showed significant increases in sustained attention compared to the control condition, correlated with increased functional connectivity in a hippocampal-prefrontal network. Notably, patients trained with videogames mostly improved in negative symptoms, general psychopathology, and perceived mental health recovery. Videogames, incorporating initiative, goal setting and gratification, offer a training approach closer to real life than current psychiatric treatments. Our results provide initial evidence that they may represent a possible adjunct therapeutic intervention for complex mental disorders.

description: The search for technological options for obtaining a solid assembly with small
values of deformations determines the need to use a combined thermal effect on the zone of
connection of extended elements made of carbon steel. Prediction of residual stress values
occurring in the heat-affected zone of an assembly is difficult because of the influence of a
significant number of factors: heat removal conditions, volume and material properties, etc.
To calculate the residual stresses in the material, an experimentally confirmed mathematical
model was used, containing viscosity and strain hardening parameters in the plastic flow
criterion.

description: We study the thermal phase transition in colour SU(3) Quantum Chromodynamics (QCD) with a variable number of fermions in the fundamental representation by using lattice Monte-Carlo simulations. We collect the (pseudo) critical couplings for N_f=(0, 4, 6,8), and we investigate the pre-conformal dynamics associated with the infra-red fixed point in terms of the N_f dependence of the transition temperature. We propose three independent estimates of the number of flavour N_f^* where the conformal phase would emerge, which give consistent results within the largish errors. We consider lines of fixed N_t in the space of (N_f, bare lattice coupling), and locate the vanishing of the step scaling function for N_f^*\sim 11.1\pm 1.6. We define a typical interaction strength (g_TC) at the scale of critical temperature T_c, and we find that g_TC meets the zero temperature critical couplings estimated by the two-loop Schwinger Dyson equation or the IRFP coupling in the four-loop beta-function at N_f^*\sim 12.5\pm 0.7. Further, we study the N_f dependences of T_c/M where M is a UV N_f independent reference scale determined by utilising the coupling at the scale of the lattice spacing. Then, T_c/M turns out to be a decreasing function of N_f, and the vanishing T_c/M indicates the emergence of the conformal window at N_f^* \sim 10.4 \pm 1.2.

Ce n'est pas sans hésitation que je crois pouvoir rapporter ce [[male]] à la Lobopelta Saussurei. Les affinités sont en tout cas si grandes que, si je me trompe, il ne peut s'agir que d'une espèce très voisine et dont l'ouvrière est encore inconnue. Ce sont surtout les différences de pilosité et de sculpture qui me font hésiter.

description: We calculate, for the first time using unquenched lattice QCD, form factors for the rare decay B -> Kll in and beyond the Standard Model. Our lattice QCD calculation utilizes a nonrelativistic QCD formulation for the b valence quarks, the highly improved staggered quark formulation for the light valence quarks, and employs the MILC 2+1 asqtad ensembles. The form factor results, based on the z expansion, are valid over the full kinematic range of q^2. We construct the ratios f0/f+ and fT/f+, which are useful in constraining new physics and verifying effective theory form factor symmetry relations. We also discuss the calculation of Standard Model observables.

description: We extend first-order logic with counting by a new operator that allows it to formalise a limited form of recursion which can be evaluated in logarithmic space. The resulting logic LREC has a data complexity in LOGSPACE, and it defines LOGSPACE-complete problems like deterministic reachability and Boolean formula evaluation. We prove that LREC is strictly more expressive than deterministic transitive closure logic with counting and incomparable in expressive power with symmetric transitive closure logic STC and transitive closure logic (with or without counting). LREC is strictly contained in fixed-point logic with counting FPC. We also study an extension LREC= of LREC that has nicer closure properties and is more expressive than both LREC and STC, but is still contained in FPC and has a data complexity in LOGSPACE. Our main results are that LREC captures LOGSPACE on the class of directed trees and that LREC= captures LOGSPACE on the class of interval graphs.

description: We propose a method to compute, for a given potential model, an arbitrary coefficient of the effective-range function expanded as a power series in energy. The method is based on a set of recurrence relations at low energy, that allows a compact and general description to any order in energy for neutral and charged cases. By using the Lagrange mesh technique to compute the R-matrix at zero energy, this proposal permits to compute, with a very good precision, the effective-range parameters. We use a potential model for some nuclear systems to illustrate the effectiveness of this method and to discuss its numerical limitations.

Grad's moment method for a granular fluid at moderate densities. Navier-Stokes transport coefficients

description: The Navier-Stokes transport coefficients of a granular dense fluid of smooth inelastic hard disks or spheres are explicitly determined by solving the inelastic Enskog equation by means of Grad's moment method. The transport coefficients are explicitly determined as functions of the (constant) coefficient of restitution and the solid volume fraction. In addition, the cooling rate is also calculated to first order in the spatial gradients. The calculations are performed for an arbitrary number of dimensions. The results are not limited to small dissipation and are expected to apply at moderate densities. It is found that the expressions of the Navier-Stokes transport coefficients and the cooling rate agree with those previously obtained from the Chapman-Enskog method by using the leading terms in a Sonine polynomial expansion. This shows the equivalence between both methods for granular fluids in the Navier-Stokes approximation. A comparison with previous results derived from Grad's moment method for inelastic disks and spheres is also carried out.

Ba & Eu Abundances in M15 giant stars

description: To investigate the Ba and Eu abundances for a sample of 63 giant stars in the globular cluster M15. This is the largest sample of M15 giants stars for which Ba abundances have been determined and, due to the target selection of the original research programme, the Ba abundances are complete along the red giant branch. Stellar parameters were taken from the previous key study and a microturbulence-surface gravity relation was determined for precise measurement of the Ba line at 6496.898 Angstroms, which has a high sensitivity to microturbulence. Element abundances for Ba, La, Eu, Ca, Ni and Fe were calculated using spectrum synthesis and equivalent widths techniques. A bimodal distribution in Ba, Eu and La abundances was found within the sample. The low Ba,Eu,La mode had mean abundances of =-2.41+/-0.16, =-1.80+/-0.08 and =-2.19+/-0.13 while the high Ba,Eu,La mode had mean abundances of =-2.00+/-0.16, =-1.65+/-0.13 and =-1.95+/-0.11. Both modes are indicative of a pollution scenario dominated by the r-process, hence contributions from explosive nucleosynthesis of massive stars. There may be evidence of further enhancement by another heavy element process and of potential anticorrelations in Na-O for both modes indicating a complex formation and evolution history for M15.

description: This novel is an exploration of my participation, as a white French-Canadian woman and educator, in a people's inquiry—an Innu community self-examination after six children died in a house fire in Davis Inlet, Labrador in 1992. It is an attempt to make meaning and learn from my 35 years of living and working with the Innu in various capacities, often from the privileged perspective of an invited guest. The research encompasses reflexive autobiography and creative writing as methods of inquiry (Clandinin 1994, Neilsen et al 2001, Ellis and Bochner 2003, Richardson 2003, Sinner et al 2006, Leavy 2013). The act of writing meshes memories and creativity, interweaving stories and voices, conversations with Innu colleagues and mentors, professors and friends; snippets of letters, emails, journals, photographs and musty files; as well as multiple readings of a wide variety of texts. I explore embodied experiences, thoughts, emotions, intuition, silences, dreams and other uncharted and unarticulated nuances, complexities, layers and territories of my work with the Innu. Postcolonial, Indigenous, feminist and critical race scholars inform investigations of representation and voice—both mine and Innu—within constructs of power, culture, class, race, gender, appropriation, subversion and complicity. I challenge assumptions about research, knowledge, truth, universality, translation, worldview and how these assumptions have failed the Innu (Spivak 1988, hooks 1990, Battiste 2004). The writing is an exercise in decolonizing my mind, of learning to learn from the disenfranchised and practicing a pedagogy of love (Freire 1970). This work responds to a call from Gail Valaskakis (2005) for new Canadian narratives to replace existing ones that pit First Peoples and newcomers against each other. The novel serves as data in support of my research, as well as a representation and report of my findings.
Elliptic flow of thermal photons from event-by-event hydrodynamic model

description: Elliptic flow of direct photons in relativistic heavy ion collisions is believed to be dominated by contribution from thermal radiation of quark gluon plasma up to $p_T$ $\sim 5$ GeV/$c$, although other sources start outshining the thermal contribution at already smaller values of $p_T$ in the direct photon spectrum. The elliptic flow of thermal photons from ideal hydrodynamics considering a smooth initial density distribution under-predicts the PHENIX direct photon data from 200A GeV Au+Au collisions at RHIC by a large margin in the range $1 < p_T < 5$ GeV/$c$. However, a significant enhancement of thermal photon production due to fluctuations in the initial QCD matter density distributions is expected. We show that such fluctuations result in substantially larger photon elliptic flow for $p_T > 2.5 $ GeV/$c$ compared to a smooth initial-state-averaged density profile. The results from event-by-event hydrodynamics are found to be sensitive to the fluctuation size parameter. However, the effects of initial state fluctuations are insufficient to account for the discrepancy to the PHENIX data for direct photon elliptic flow. Furthermore, the photon $v_2$ is reduced even more when we include the NLO pQCD prompt photon component. We also calculate the spectra and elliptic flow of thermal photons for 2.76A TeV Pb+Pb collisions at LHC and for the 0--40% centrality bin. Thermal photons from event-by-event hydrodynamics along with prompt photons from NLO pQCD calculations explain the ALICE preliminary direct photon data well in the region $p_T \ge 2.5$ GeV/c. Similar to RHIC, the elliptic flow results at LHC are again found to be much smaller than the ALICE preliminary $v_2$ data.
