description: Veselago pointed out that electromagnetic wave theory allows for materials with a negative index of refraction, in which most known optical phenomena would be reversed. A slab of such a material can focus light by negative refraction, an imaging technique strikingly different from conventional positive refractive index optics, where curved surfaces bend the rays to form an image of an object. Here we demonstrate Veselago lensing for matter waves, using ultracold atoms in an optical lattice. A relativistic, i.e. photon-like, dispersion relation for rubidium atoms is realized with a bichromatic optical lattice potential. We rely on a Raman $π$-pulse technique to transfer atoms between two different branches of the dispersion relation, resulting in a focusing completely analogous to the effect described by Veselago for light waves. Future prospects of the demonstrated effects include novel sub-de Broglie wave imaging applications.

description: Wellbeing of children and young people (YP) in the UK is a national concern, which has resulted in an increased empirical and policy interest in this topic. While Black students appear to be at higher risk of wellbeing problems, there is limited evidence on what school support is effective for this student group. Additionally, previous research has predominantly focused on within-child wellbeing interventions, which have been ‘done to’ rather than ‘done with’ students. This reinforces the deficit narratives surrounding Black students’ wellbeing and disregards systemic factors that exacerbate it (e.g. racial discrimination). Accordingly, the present study adopts solution-oriented (Harker et al., 2016) and social-ecological lenses (Ungar et al., 2007) to identify what school wellbeing provisions are viewed as helpful by young Black people. This study aimed to be culturally sensitive and to empower the researched community, thus a participatory research approach was employed. Two co-researchers provided guidance on the data collection and dissemination approach of this study. Subsequently, 10 young Black people between the ages of 13 and 21 participated in semi-structured interviews. Data was transcribed verbatim and was, then, analysed inductively using Reflexive Thematic Analysis (Clarke & Braun, 2022). The findings were applied to Ungar et al.’s (2007) social-ecological model, illustrating the different systemic factors contributing to young Black people’s wellbeing at school. These included personal factors facilitating pupils’ resilience, support from key attachment figures at school, needs-driven and accessible whole-school wellbeing provisions, and, crucially, positive and inclusive school ethos. Students suggested that the available support could be improved by promoting anti-discriminatory approaches, reducing academic pressures, incorporating pupil voice into provisions, and providing wellbeing check-ins. Finally, the implications of this study’s findings for Educational Psychology practice are discussed, before concluding with the author’s reflections on her research journey

description: Roughly half of the radiation from evolving galaxies in the early universe reaches us in the far-infrared and submillimeter wavelength range. Recent major advances in observing capabilities, in particular the launch of the Herschel Space Observatory in 2009, have dramatically enhanced our ability to use this information in the context of multiwavelength studies of galaxy evolution. Near its peak, three quarters of the cosmic infrared background is now resolved into individually detected sources. The use of far-infrared diagnostics of dust-obscured star formation and of interstellar medium conditions has expanded from rare extreme high-redshift galaxies to more typical main sequence galaxies and hosts of active galactic nuclei, out to z>~2. These studies shed light on the evolving role of steady equilibrium processes and of brief starbursts, at and since the peak of cosmic star formation and black hole accretion. This review presents a selection of recent far-infrared studies of galaxy evolution, with an emphasis on Herschel results

title: Exploring the interplay between innate and adaptive immune responses to live attenuated influenza vaccine in Gambian children
Creators: name: Jagne, Ya Jankey
Publisher: name: The Open University
Year: 2023

description: Influenza vaccination remains a challenge in low and middle income countries despite high rates of mortality and morbidity in children. World Health Organization and Serum Institute of India developed Nasovac-S, a single dose influenza vaccine to increase vaccine accessibility in these regions. The vaccine was trialled in some African Countries but no immunogenicity data was collected.

This thesis aimed to characterize the innate and adaptive immune responses pre and post LAIV in Gambian children and explore the relationship between the two responses post vaccination.

This study was nested within a randomised controlled trial investigating LAIV–microbiome interactions (NCT02972957) in healthy children aged 24–59 months who receive one dose of the WHO prequalified Russian-backbone trivalent LAIV containing A/17/California/2009/38 (Cal09) in 2017 and A/17/New York/15/5364 (NY15) in 2018. Cellular and humoral immune responses and phenotypes of immune cells pre and post LAIV were assessed using multi-parameter flow cytometry. Follicular helper T (Tfh) cells, were also investigated using the activation induced marker assay.

Post LAIV, decreased frequency of classical monocytes and increased frequency of intermediate monocytes in Gambian children was noted. Increased frequency of CD4+T cells but not CD8+T cells was also noted. LAIV induced bulk and influenza specific Tfh cells associated with seroconversion.

Change in the H1N1 strain of the vaccine in 2018 led to differences in viral shedding, replication and greater immunogenicity post LAIV. Further investigations determined that differences in immune responses observed between the two study vaccines were a result of a reduced replicative capacity of the pH1N1 Cal09 virus compared to pH1N1 NY15.

A single dose of LAIV in Gambian children led to perturbation of innate and adaptive immune cells post LAIV. Seroconversion post LAIV was associated with increase in frequency of intermediate monocytes and Tfh cells. Immunogenicity is also dependent on strain-selection for inclusion in influeza vaccine.

description: We investigate the dynamical nature of the collapse process of a spherically symmetric star in quasi-static hydrodynamical equilibrium. The star collapses from an initial static configuration by dissipating energy in the form of a radial heat flux. The dissipation ensures that the singularity is never formed and the stellar mass completely evaporates over a finite time.

description: We study pion induced reactions for charmed baryons $B$, $π$ + N $\rightarrow$ $D^*$ + $B$. First we estimate charm production rates in comparison with strangeness production using a Regge model which is dominated by vector ($D^*$ or $K^*$ ) Reggeon exchange. Then we examine the production rates of various charmed baryons $B$ in a quark-diquark model. We find that the production of excited states are not necessarily suppressed, a sharp contrast to strangeness production, which is a unique feature of the charm production with a large momentum transfer.

description: New forms of electron beams have been intensively investigated recently, including vortex beams carrying orbital angular momentum, as well as Airy beams propagating along a parabolic trajectory. Their traits may be harnessed for applications in materials science, electron microscopy and interferometry, and so it is important to measure their properties with ease. Here we show how one may immediately quantify these beams' parameters without need for additional fabrication or non-standard microscopic tools. Our experimental results are backed by numerical simulations and analytic derivation.

description: Single junction Si solar cells dominate photovoltaics but are close to their efficiency limits. This paper presents ideal limiting efficiencies for tandem and triple junction multijunction solar cells subject only to the constraint of the Si bandgap and therefore recommending optimum cell structures departing from the single junction ideal. The use of III-V materials is considered, using a novel growth method capable of yielding low defect density III-V layers on Si. In order to evaluate the real potential of these proposed multijunction designs, a quantitative model is presented, the strength of which is the joint modelling of external quantum efficiency and current-voltage characteristics using the same parameters. The method yields a single parameter fit in terms of the Shockley-Read-Hall lifetime. This model is validated by fitting experimental data of external quantum efficiency, dark current, and conversion efficiency of world record tandem and triple junction cells under terrestrial solar spectra without concentration. We apply this quantitative model to the design of tandem and triple junction solar cells, yielding cell designs capable of reaching efficiencies without concentration of 32% for the best tandem cell and 36% for the best triple junction cell. This demonstrates that efficiencies within a few percent of world records are realistically achievable without the use of concentrating optics, with growth methods being developed for multijunction cells combining III-V and Si materials.

description: SUMMARY: The presence of precursor to exhausted (Tpex) CD8+ T cells is important to maintain robust immunity following treatment with immune checkpoint inhibition (ICI). Impressive responses to ICI are emerging in patients with stage II-III mismatch repair (MMR)-deficient (dMMR) colorectal cancer (CRC). We found 64% of dMMR and 15% of mismatch repair-proficient (pMMR) stage III CRCs had a high frequency of tumor infiltrating lymphocytes (TIL-hi). Furthermore, expression of TCF-1 (Tcf7) by CD8+ T cells predicted improved patient prognosis and Tpex cells (CD3+CD8+ TCF-1+PD-1+) were abundant within lymphoid aggregates of stage III CRCs. In contrast, CD3+CD8+TCF-1?PD-1+ cells were more abundant at the invasive front and tumor core, while gd T cells were equally abundant in all tumor areas. Interestingly, no differences in the frequency of Tpex cells were observed between TIL-hi dMMR and TIL-hi pMMR CRCs. Therefore, Tpex cell function and ICI response rates in TIL-hi CRC warrants further investigation.

description: There has been a long-lasting debate on the question of whether or not electric currents in solar active regions are neutralized. That is, whether or not the main (or direct) coronal currents connecting the active region polarities are surrounded by shielding (or return) currents of equal total value and opposite direction. Both theory and observations are not yet fully conclusive regarding this question, and numerical simulations have, surprisingly, barely been used to address it. Here we quantify the evolution of electric currents during the formation of a bipolar active region by considering a three-dimensional magnetohydrodynamic simulation of the emergence of a sub-photospheric, current-neutralized magnetic flux rope into the solar atmosphere. We find that a strong deviation from current neutralization develops simultaneously with the onset of significant flux emergence into the corona, accompanied by the development of substantial magnetic shear along the active region's polarity inversion line. After the region has formed and flux emergence has ceased, the strong magnetic fields in the region's center are connected solely by direct currents, and the total direct current is several times larger than the total return current. These results suggest that active regions, the main sources of coronal mass ejections and flares, are born with substantial net currents, in agreement with recent observations. Furthermore, they support eruption models that employ pre-eruption magnetic fields containing such currents.

description: In this paper, we look into the problem of channel assignment in multi-channel multi-radio wireless mesh networks. We propose a new learning automata based channel assignment scheme that adaptively improve network overall throughput by expecting channel state. Since the ability of sending packets via upstream links will be evaluation bases for assigning channels to radio interfaces on each node. We use a link capacity function that potentially reflects degree of interferences imposed by selected channels by each node. According to dynamics of system, proposed algorithm assigns channels to radio interface in distributed fashion such that minimize interference in neighborhood of a node. We analyze the stability of the system via appropriate Lyapunov-like trajectory; we show that stability and optimum point of the system is converged.

description: Recent null results from LHC8 SUSY searches along with the discovery of a SM-like Higgs boson with mass m(h) ~ 125.5 GeV indicates sparticle masses in the TeV range, causing tension with conventional measures of electroweak fine-tuning. We propose a simple Fine-tuning Rule which should be followed under any credible evaluation of fine-tuning. We believe that overestimates of electroweak fine-tuning by conventional measures all arise from violations of this rule. We show that to gain accord with the Fine-tuning Rule, then both Higgs mass and the traditional Δ_{BG} fine-tuning measures reduce to the model-independent electroweak fine-tuning measure Δ_{EW}. This occurs by combining dependent contributions to m(Z) or m(h) into independent units. Then, using Δ_{EW}, we evaluate EW fine-tuning for a variety of SUSY models including mSUGRA, NUHM1, NUHM2, mGMSB, mAMSB, hyper-charged AMSB and nine cases of mixed moduli-anomaly (mirage) mediated SUSY breaking models (MMAMSB) whilst respecting LHC Higgs mass and B-decay constraints (we do not impose LHC8 sparticle mass constraints due to the possibility of compressed spectra within many of these models). We find mSUGRA, mGMSB, mAMSB and MMAMSB models all to be highly fine-tuned. The NUHM1 model is moderately fine-tuned while NUHM2 which allows for radiatively-driven naturalness (RNS) allows for fine-tuning at a meager 10% level in the case where m(higgsinos) ~ 100-200 GeV and the TeV-scale top squarks are well-mixed. Models with RNS may or may not be detect at LHC14. A \sqrt{s} ~ 500 GeV e^+e^- collider will be required to make a definitive search for the requisite light higgsinos.

description: We investigate Stein-Malliavin approximations for nonlinear functionals of geometric interest of Gaussian random eigenfunctions on the unit $d$ -dimensional sphere ${\mathbb{S}}^{d},$ $d\geq 2.$ All our results are established in the high energy limit, i.e. for eigenfunctions corresponding to growing eigenvalues. More precisely, we provide an asymptotic analysis for the variance of random eigenfunctions, and also establish rates of convergence for various probability metrics for Hermite subordinated processes, arbitrary polynomials of finite order and square integral nonlinear transforms; the latter, for instance, allows to prove a quantitative Central Limit Theorem for the excursion area. Some related issues were already considered in the literature for the $2$-dimensional case ${\mathbb{S}}^{2}$; our results are new or improve the existing bounds even for this special case. Proofs are based on the asymptotic analysis of moments of all order for Gegenbauer polynomials, and make extensive use of the recent literature on so-called fourth-moment theorems by Nourdin and Peccati.

description: For the past decade observations of the alignement of PNe symmetries with respect to the galactic disk have led to conflicting results. Recently observational evidence for alignment between PNe and local interstellar magnetic fields in the central part of the Galaxy ($b < 5^\circ$) has been found. We studied the role of the interstellar magnetic field on the dynamical evolution of a PN by means of an analytical model and from 3D MHD numerical simulations. We test under what conditions typical ejecta would have their dynamics severely modified by an interstellar magnetic field. We found that uniform fields of $> 100μ$G are required in order to be dynamically dominant. This is found to occur only at later evolutionary stages, therefore being unable to change the general morphology of the nebula. However, the symmetry axis of bipolar and elliptical nebulae end up aligned to the external field. This result can explain why different samples of PNe result in different conclusions regarding the alignment of PNe. Objects located at high galactic latitudes, or at large radii, should present no preferential alignment with respect to the galactic plane. PNe located at the galactic centre and low latitudes would, on the other hand, be preferentiably aligned to the disk. Finally, we present synthetic polarization maps of the nebulae to show that the polarization vectors, as well as the field lines at the expanding shell, are not uniform even in the strongly magnetized case, indicating that polarization maps of nebulae are not adequate in probing the orientation, or intensity, of the dominant external field.

Linguistic markers for French teenagers with DLD (Courteau et al., 2023)

description: Purpose: This research aimed to identify reliable tasks discriminating French-speaking adolescents with developmental language disorder (DLD) from their peers with typical language (TL) and to assess which linguistic domains represent areas of particular weakness in DLD. Unlike English, morphosyntax has not been identified as a special area of weakness when compared with lexicosemantics in French preschoolers with DLD. Since there is evidence that subject–verb number agreement is consolidated in later childhood, one might expect morphosyntax to be a particular weakness and marker of French DLD only in (pre)adolescence. Method: We administered 20 subtasks that assessed linguistic and phonological working memory skills of two groups: 17 adolescents clinically identified as having DLD (M = 14;09 [years;months]) and 20 (pre)teens with TL (M = 12;21). Using robust statistics that are less affected by outliers, we selected the most discriminating subtasks between our groups, calculated their optimal cutoff score, and derived diagnostic accuracy statistics. We combined these subtasks in a multivariable model to identify which subtasks contributed the most to the identification of DLD. Results: Seven subtasks were selected as discriminating between our groups, and three showed outstanding diagnostic accuracy: Recalling Sentences, a multiword task assessing lexicosemantic skills, and a subject–verb number agreement production task. When combined, we found that the latter contributed the most to our multivariable model. Conclusion: This study provides evidence that the most relevant markers to identify DLD in French teenagers are tasks assessing lexicosemantics and morphosyntactic domains, and that morphosyntax should be considered an important area of weakness in French-speaking teenagers with DLD.

description: Multipartite Quantum Correlations is one of the most relevant indicator of the quantumness of a system in many body systems. This remarkable feature is in general difficult to characterize and the known definitions are hard to measure. Besides the efforts dedicated to solve this problem, the question of which is the best approach remains open. In this work, we study the Global Quantum Discord, GQD, as a bipartite and multipartite measure. We also check the limits of this definitions and present an experimental scheme to determine the maximum of the GQD via the measurements of the system's excitations, during the time evolution of the present system.

Para conseguirmos compreender esse problema, definimos os seguintes objetivos: traçar o perfil dos professores que trabalham com alunos com deficiência; identificar quem são os alunos atendidos pelos professores; identificar as estratégias adotadas pela instituição e pelos docentes para atender aos alunos e identificar as principais dificuldades encontradas pelos docentes nesse atendimento. O intuito foi chegar aos objetivos, a fim de abranger o tema educação inclusiva e suas implicações, abordando os desafios pelos professores frente à temática educação inclusiva. A inclusão acontece quando percebida como inserção dos alunos na escola, sendo compreendidas apenas como aquelas relacionadas às limitações físicas e intelectuais. Apesar do discurso docente de que os professores estão preparados para o atendimento aos alunos com deficiências, outras informações nos apontam a falta de formação e capacitação profissional dos professores, bem como a inexistência de materiais e espaços adequados a esse atendimento, indicando a necessidade de melhor se discutir a inclusão nas escolas, a formação docente e estratégias adequadas para o atendimento aos alunos e a inclusão dos mesmos no contexto educacional, demostrando e aguçando suas habilidades e importância no meio social. O professor é o norteador e facilitador para que a inclusão ocorra de forma igualitária e satisfatória. Lidar com o novo é algo assustador, porém moldando as habilidades docentes facilita o processo inclusivo dos alunos assistidos.

description: We implement the metric-independent Fock-Schwinger gauge in the abelian quantum Chern-Simons field theory defined in ${\mathbb R}^3$. The expressions of the various components of the propagator are determined. Although the gauge field propagator differs from the Gauss linking density, we prove that its integral along two oriented knots is equal to the linking number.

description: The channel capacity of a nonlinear, dispersive fiber-optic link is revisited. To this end, the popular Gaussian noise (GN) model is extended with a parameter to account for the finite memory of realistic fiber channels. This finite-memory model is harder to analyze mathematically but, in contrast to previous models, it is valid also for nonstationary or heavy-tailed input signals. For uncoded transmission and standard modulation formats, the new model gives the same results as the regular GN model when the memory of the channel is about 10 symbols or more. These results confirm previous results that the GN model is accurate for uncoded transmission. However, when coding is considered, the results obtained using the finite-memory model are very different from those obtained by previous models, even when the channel memory is large. In particular, the peaky behavior of the channel capacity, which has been reported for numerous nonlinear channel models, appears to be an artifact of applying models derived for independent input in a coded (i.e., dependent) scenario.

description: Purpose: This feasibility study examined a caregiver-implemented telehealth model of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) protocol. We asked whether caregivers could reach fidelity on VAULT, if the protocol was socially and ecologically valid, and if late-talking toddlers could learn new words with this model. Method: Five late-talking monolingual and bilingual toddlers and four caregivers participated. The caregiver-related research questions involved measurements taken at multiple time points and replication across subjects but did not follow a specific research design. The toddler-related research questions included elements of a single-case design. Caregivers completed self-paced online training modules and then provided 8 weeks of VAULT to their children with remote coaching. Fidelity data were collected during coached sessions and through rating scales. Social and ecological validity data were collected via surveys and interviews. Children’s word learning was measured before, during, and after treatment via production of targets and controls and via standardized vocabulary inventories. Results: Caregivers demonstrated high fidelity to VAULT throughout treatment. They reported being comfortable with many aspects of VAULT. Feedback was mixed regarding the time required. Many reported their child was talking more as a result of the program. Visual analysis revealed that toddlers learned more target than control words, which was corroborated by Tau-U and d effect size analyses. Conclusion: A caregiver-implemented telehealth model of VAULT was feasible, was socially and ecologically valid, and benefited toddlers, making this a worthwhile model for future studies to examine.

description: Les patient·e·s souffrant de cancer de la sphère oto-rhino-laryngologique (ORL) rencontrent une multitude de symptômes physiques et psychologiques liés tant à la maladie qu’aux différentes approches thérapeutiques. De par leur localisation, ces types de cancers affectent aussi bien l’image corporelle que certaines fonctions fondamentales comme la déglutition, la respiration et la communication. Ces particularités rendent la prise en charge complexe et amènent un défi majeur pour les soignant·e·s.

description: We study a semiclassical random walk with respect to a probability measure with a finite number n_0 of wells. We show that the associated operator has exactly n_0 exponentially close to 1 eigenvalues (in the semiclassical sense), and that the other are O(h) away from 1. We also give an asymptotic of these small eigenvalues. The key ingredient in our approach is a general factorization result of pseudodifferential operators, which allows us to use recent results on the Witten Laplacian.

description: We consider the $U(1)$ Chern-Simons gauge theory defined in a general closed oriented 3-manifold $M$; the functional integration is used to compute the normalized partition function and the expectation values of the link holonomies. The nonperturbative path-integral is defined in the space of the gauge orbits of the connections which belong to the various inequivalent $U(1)$ principal bundles over $M$; the different sectors of the configuration space are labelled by the elements of the first homology group of $M$ and are characterized by appropriate background connections. The gauge orbits of flat connections, whose classification is also based on the homology group, control the extent of the nonperturbative contributions to the mean values. The functional integration is achieved in any 3-manifold $M$, and the corresponding path-integral invariants turn out to be strictly related with the abelian Reshetikhin-Turaev surgery invariants.
