description: Hybrid quantum systems exhibiting coupled optical, spin, and mechanical degrees of freedom can serve as a platform for sensing, or as a bus to mediate interactions between qubits with disparate energy scales. These systems are also creating opportunities to test foundational ideas in quantum mechanics, including direct observations of the quantum regime in macroscopic objects. Here, we make use of angular momentum conservation to study the dynamics of a pair of paramagnetic centers featuring different spin numbers in the presence of a properly tuned external magnetic field. We examine the interplay between optical excitation, spin evolution, and mechanical motion, and theoretically show that in the presence of continuous optical illumination, inter-spin cross-relaxation must induce rigid rotation of the host crystal. The system dynamics is robust to scattering of spin-polarized phonons, a result we build on to show this form of angular momentum transfer should be observable using state-of-the-art torsional oscillators or trapped nanoparticles.

First normal stress difference and crystallization in a dense sheared granular fluid

description: The first normal stress difference (${\mathcal N}_1$) and the microstructure in a dense sheared granular fluid of smooth inelastic hard-disks are probed using event-driven simulations. While the anisotropy in the second moment of fluctuation velocity, which is a Burnett-order effect, is known to be the progenitor of normal stress differences in {\it dilute} granular fluids, we show here that the collisional anisotropies are responsible for the normal stress behaviour in the {\it dense} limit. As in the elastic hard-sphere fluids, ${\mathcal N}_1$ remains {\it positive} (if the stress is defined in the {\it compressive} sense) for dilute and moderately dense flows, but becomes {\it negative} above a critical density, depending on the restitution coefficient. This sign-reversal of ${\mathcal N}_1$ occurs due to the {\it microstructural} reorganization of the particles, which can be correlated with a preferred value of the {\it average} collision angle $θ_{av}=π/4 \pm π/2$ in the direction opposing the shear. We also report on the shear-induced {\it crystal}-formation, signalling the onset of fluid-solid coexistence in dense granular fluids. Different approaches to take into account the normal stress differences are discussed in the framework of the relaxation-type rheological models.

description: Résumé

Le but de ce travail est d’analyser les obstacles á la mise en œuvre de la Gestion Prévisionnelle des Emplois, des Effectifs et des Compétences (GPEEC) dans l’administration publique gabonaise. La méthodologie utilisée consiste à une analyse factorielle exploratoire et confirmatoire des données permettant de saisir les facteurs explicatifs latents, l’intérêt des régressions linéaires binaires afin de saisir les déterminants, et l’usage de la méthode des Moindres Carrés Généralisés permettant d’analyser le canal de transmission. Les principaux résultats indiquent une dispersion hétérogène des opinions sur les obstacles à caractère aléatoire entre les administrations publiques qui se manifestent de façon psychologique et morale. Les estimations montrent que les obstacles de la GPEEC, la qualité de la GRH, les effectifs, la nature du sexe et l’unité organique constituent le moteur des freins aux aspirations des responsables en charge de la GRH. En outre, il est justifié que la GPEEC est un canal de transmission de la GRH à un système de fonction publique orienté à l’optimalité de gestion de carrière comme outil stratégique.

description: This work proposes a novel Graph-based neural ArchiTecture Encoding Scheme, a.k.a. GATES, to improve the predictor-based neural architecture search. Specifically, different from existing graph-based schemes, GATES models the operations as the transformation of the propagating information, which mimics the actual data processing of neural architecture. GATES is a more reasonable modeling of the neural architectures, and can encode architectures from both the "operation on node" and "operation on edge" cell search spaces consistently. Experimental results on various search spaces confirm GATES's effectiveness in improving the performance predictor. Furthermore, equipped with the improved performance predictor, the sample efficiency of the predictor-based neural architecture search (NAS) flow is boosted. Codes are available at https://github.com/walkerning/aw_nas.

description: Veterans who transition out of the military often face substantive challenges during their move to civilian life, which include identifying appropriate opportunities for employment, supporting their respective families, and developing high-quality social connections within their civilian lives more generally. The importance of social connectivity, in particular, has recently been highlighted as an important mechanism that can facilitate improved mental health and quality of life among veterans, and represents a viable target for intervention. The purpose of the study was to examine military veterans’ experiences of Purpose After Service through Sport (PASS) which is a sport-based program, in Canada, underpinned by the social identity approach. We recruited participants (Mage= 39.83, SD = 8.07, Myears of service= 15.63, SD = 9.60), and using semi-structured interviews and reflexive thematic analysis, identified several aspects of the program that participants experienced and considered important. These included a variety of positive benefits (mental and physical health, social connections, and access to resources), as well as military identity as a means of supporting social connectivity. Participants also commented on salient environmental features of the program that supported their involvement, as well as suggestions for program refinement. The study provides evidence for the feasibility and acceptability of the PASS program as well as insight into veterans’ experiences of this initiative. Future research should examine the efficacy/effectiveness of the PASS program to support effective transitions and quality of life outcomes among military veterans using causal (e.g., randomized trial) research designs.

description: We develop a method to compute the Casimir effect for arbitrary geometries. The method is based on the string-inspired worldline approach to quantum field theory and its numerical realization with Monte-Carlo techniques. Concentrating on Casimir forces between rigid bodies induced by a fluctuating scalar field, we test our method with the parallel-plate configuration. For the experimentally relevant sphere-plate configuration, we study curvature effects quantitatively and perform a comparison with the ``proximity force approximation'', which is the standard approximation technique. Sizable curvature effects are found for a distance-to-curvature-radius ratio of a/R >~ 0.02. Our method is embedded in renormalizable quantum field theory with a controlled treatment of the UV divergencies. As a technical by-product, we develop various efficient algorithms for generating closed-loop ensembles with Gaussian distribution.

We demonstrate improvements in accuracy ranging from 2.3x to 12.5x (5.03x on average) for the tested ScalaBench (and DaCapo) workloads, and from 23.8x to 82.4x (37.4x on average) for the SPEC CPU 2017 workloads.

description: We investigate electron spin currents induced optically via plasmonic modes in the Kretschmann configuration. By utilising the scattering matrix formalism, we take the plasmonic mode coupled to external laser drive into consideration and calculate induced magnetisation in the metal. The spatial distribution of the plasmonic mode is inherited by the induced magnetisation, which acts as inhomogeneous effective magnetic field and causes the Stern-Gerlach effect to drive electron spin currents in the metal. We solve spin diffusion equation with a source term to analyse the spin current as a function of the spin diffusion length of the metal, the frequency and the incident angle of the external drive.

An XMM-Newton observation of the massive, relaxed galaxy cluster ClJ1226.9+3332 at z=0.89

description: A detailed X-ray analysis of an XMM-Newton observation of the high-redshift (z=0.89) galaxy cluster ClJ1226.9+3332 is presented. The X-ray temperature is found to be 11.5{+1.1}{-0.9}keV, the highest X-ray temperature of any cluster at z>0.6. In contrast to MS1054-0321, the only other very hot cluster currently known at z>0.8, ClJ1226.9+3332 features a relaxed X-ray morphology, and its high overall gas temperature is not caused by one or several hot spots. The system thus constitutes a unique example of a high redshift, high temperature, relaxed cluster, for which the usual hydrostatic equilibrium assumption, and the X-ray mass is most reliable. A temperature profile is constructed (for the first time at this redshift) and is consistent with the cluster being isothermal out to 45% of the virial radius. Within the virial radius (corresponding to a measured overdensity of a factor of 200), a total mass of (1.4+/-0.5)*10^15 M_solar is derived, with a gas mass fraction of 12+/-5%. The bolometric X-ray luminosity is (5.3+/-0.2)*10^45 erg/s. The probabilities of finding a cluster of this mass within the volume of the discovery X-ray survey are 8*10^{-5} for Omega_M=1 and 0.64 for Omega_M=0.3, making Omega_M=1 highly unlikely. The entropy profile suggests that entropy evolution is being observed. The metal abundance (of Z=0.33{+0.14}{-0.10} Z_solar), gas mass fraction, and gas distribution are consistent with those of local clusters; thus the bulk of the metals were in place by z=0.89.

description: The quark hadron phase transition in a rotating compact star has been studied. The NLZ-model has been used for the hadronic sector and the MIT Bag model has been used for the quark sector. It has been found that rotating twin star (third family) solutions are obtained upto $Ω\approx 4000 s^{-1}$. Stars which are rotating faster than this limit do not show any twin star solution. A backbending in moment of inertia is also observed in the supermassive rest mass sequences. The braking index is found to diverge for a star having pure quark core.

description: We report on the development of a high-power mid-infrared frequency comb with 100 MHz repetition rate and 100 fs pulse duration. Difference frequency generation is realized between two branches derived from an Er:fiber comb, amplified separately in Yb:fiber and Er:fiber amplifiers. Average powers of 6.7 W and 14.9 W are generated in the 2.9 $μ$m idler and 1.6 $μ$m signal, respectively. With high average power, excellent beam quality, and passive carrier-envelope phase stabilization, this light source is a promising platform for generating broadband frequency combs in the far infrared, visible, and deep ultraviolet.

description: Palm wine is of high nutritional and economic importance and plays a significant role in cultural and social practices in Africa. Since the nutritional content is high, there is proliferation of microorganism which results in spontaneous fermentation. The microbiological quality of different palm wine samples was investigated and it was found to harbor microorganisms such as Lactobacillus sp, Micrococcus sp, Staphylococcus sp, Streptococcus sp and Bacillus sp. This had a count of 0.8 x 103 – 1.8 x 103 CFU/ml and 1.2 x 103 – 3.8 x 103 CFU/ml for different samples. The isolation of these microorganisms from these product is of public health concern because this product is on high demand in this area and beyond. With the result of this study, public awareness has to be created on the risk factors involved in the consumption of palm wine and the need to imbibe proper sanitary hygienic practice in tapping, processing, diluting and distribution of the product.

description: Temperature dependences of the magnetic moment have been measured in YBa_2Cu_3O_{7-δ} thin films over a wide magnetic field range (5 <= H <= 10^4 Oe). In these films a paramagnetic signal known as the paramagnetic Meissner effect has been observed. The experimental data in the films, which have strong pinning and high critical current densities (J_c ~ 2 \times 10^6 A/cm^2 at 77 K), are quantitatively shown to be highly consistent with the theoretical model proposed by Koshelev and Larkin [Phys. Rev. B 52, 13559 (1995)]. This finding indicates that the origin of the paramagnetic effect is ultimately associated with nucleation and inhomogeneous spatial redistribution of magnetic vortices in a sample which is cooled down in a magnetic field. It is also shown that the distribution of vortices is extremely sensitive to the interplay of film properties and the real experimental conditions of the measurements.

description: Porous metallic structures are regularly used in electrochemical energy storage devices as supports, current collectors or active electrode materials. Bulk metal porosification, dealloying, welding or chemical synthesis routes involving crystal growth or self-assembly for example, can sometimes provide limited control of porous length scale, ordering, periodicity, reproducibility, porosity and surface area. Additive manufacturing and 3D printing has shown the potential to revolutionize the fabrication of architected metals many forms, allowing complex geometries not usually possible by traditional methods, but enabling complete design freedom of a porous metal based on the required physical or chemical property to be exploited. We discuss properties of porous metal structures in EES devices and provide some opinions on how architected metals may alleviate issues with electrochemically active porous metal current collectors, and provide opportunities for optimum design based on electrochemical characteristics required by batteries, supercapacitors or other electrochemical devices.

Theory of the tertiary instability and the Dimits shift within a scalar model

description: The Dimits shift is the shift between the threshold of the drift-wave primary instability and the actual onset of turbulent transport in magnetized plasma. It is generally attributed to the suppression of turbulence by zonal flows, but developing a more detailed understanding calls for consideration of specific reduced models. The modified Terry--Horton system has been proposed by St-Onge [J. Plasma Phys. $\boldsymbol{\rm 83}$, 905830504 (2017)] as a minimal model capturing the Dimits shift. Here, we use this model to develop an analytic theory of the Dimits shift and a related theory of the tertiary instability of zonal flows. We show that tertiary modes are localized near extrema of the zonal velocity $U(x)$, where $x$ is the radial coordinate. By approximating $U(x)$ with a parabola, we derive the tertiary-instability growth rate using two different methods and show that the tertiary instability is essentially the primary drift-wave instability modified by the local $U''$. Then, depending on $U''$, the tertiary instability can be suppressed or unleashed. The former corresponds to the case when zonal flows are strong enough to suppress turbulence (Dimits regime), while the latter corresponds to the case when zonal flows are unstable and turbulence develops. This understanding is different from the traditional paradigm that turbulence is controlled by the flow shear $U'$. Our analytic predictions are in agreement with direct numerical simulations of the modified Terry--Horton system.

description: Internet-of-Things (IoT) systems are becoming increasingly complex, heterogeneous and pervasive, integrating a variety of physical devices and virtual services that are spread across architecture layers (cloud, fog, edge) using different connection types. As such, research and design of such systems have proven to be challenging. Despite the influx in IoT research and the significant benefits of simulation-based approaches in supporting research, there is a general lack of appropriate modelling and simulation platforms to create a detailed representation of end-to-end IoT services, i.e. from the underlying IoT nodes to the application layer in the cloud along with the underlying networking infrastructure. To aid researchers and practitioners in overcoming these challenges, we propose IoTNetSim, a novel self-contained extendable platform for modelling and simulation of end-to-end IoT services. The platform supports modelling heterogeneous IoT nodes (sensors, actuators, gateways, etc.) with their fine-grained details (mobility, energy profile, etc.), as well as different models of application logic and network connectivity. The proposed work is distinct from the current literature, being an all-in-one tool for end-to-end IoT services with a multi-layered architecture that allows modelling IoT systems with different structures. We experimentally validate and evaluate our IoTNetSim implementation using two very large-scale real-world cases from the natural environment and disaster monitoring IoT domains.

description: Monoculture and rotation systems usually exhibit distinct diversity and composition of microbial community in the cultivation of various plants, but the network structures and keystone species of microbial communities in these two cropping systems are poorly understood. To better understand this issue, we constructed four ecological networks of bacterial communities in bulk and rhizosphere soils of soybean grown in the two cropping systems, i.e. continuous cropping of soybean (CC) and acropping rotation with maize (CR), using Molecular Ecological Network Analysis Pipeline (MENAP). The results revealed that the bacterial network structure and composition between the two cropping systems in both bulk and rhizosphere soils were greatly different, with larger differences between CC and CR in rhizosphere soils than in bulk soils. Compared with CC, CR increased the stability and complexity of bacterial networks in both bulk and rhizosphere soils. Predominantly positive (> 75%) correlations in all the networks indicated that extensive cooperative interactions occurred among bacterial taxa in Mollisols. Putative keystone species that typically had low relative abundance performed distinct ecological functions in the two cropping systems.

description: We have mapped the dust continuum emission from the molecular cloud covering a region of 28pcx94pc associated with the well-known HII region RCW 106 at 1.2 mm using SIMBA on SEST. The observations, having an HPBW of 24" (0.4 pc), reveal 95 clumps. Owing to the higher sensitivity to colder dust and higher angular resolution the present observations identify new emission features and also show that most of the IRAS sources in this region consist of multiple dust emission peaks. The detected millimeter sources (MMS) include on one end the exotic MMS5 (associated with IRAS 16183-4958, one of the brightest infrared sources in our Galaxy) and the bright (and presumably cold) source MMS54, with no IRAS or MSX associations on the other end. Around 10% of the sources are associated with signposts of high mass star formation activity. Assuming a uniform dust temperature of 20 K we estimate the total mass of the GMC associated with RCW 106 to be ~10^5\msun. The constituent millimeter clumps cover a range of masses and radii between 40 to 10^4 \msun and 0.3 to 1.9 pc. Densities of the clumps range between (0.5-6) 10^4 cm^{-3}. We have decomposed the continuum emission into gaussian and arbitrary shaped clumps using the two independent structure analysis tools gaussclumps and clumpfind respectively. The clump mass spectrum was found to have an index of 1.6+-0.3, independent of the decomposition algorithm used. The index of the mass spectrum for the mass and length scales covered here are consistent with results derived from large scale CO observations.

description: The Deep Ecliptic Survey is a project whose goal is to survey a large area of the near-ecliptic region to a faint limiting magnitude (R ~ 24) in search of objects in the outer solar system. We are collecting a large homogeneous data sample from the Kitt Peak Mayall 4-m and Cerro Tololo Blanco 4-m telescopes with the Mosaic prime-focus CCD cameras. Our goal is to collect a sample of 500 objects with good orbits to further our understanding of the dynamical structure of the outer solar system. This survey has been in progress since 1998 and is responsible for 272 designated discoveries as of March 2003. We summarize our techniques, highlight recent results, and describe publically available resources.

description: In this paper, we present a visual emulator of the emotions seen in characters in stories. This system is based on a simplified view of the cognitive structure of emotions proposed by Ortony, Clore and Collins (OCC Model). The goal of this paper is to provide a visual platform that allows us to observe changes in the characters' different emotions, and the intricate interrelationships between: 1) each character's emotions, 2) their affective relationships and actions, 3) The events that take place in the development of a plot, and 4) the objects of desire that make up the emotional map of any story. This tool was tested on stories with a contrasting variety of emotional and affective environments: Othello, Twilight, and Harry Potter, behaving sensibly and in keeping with the atmosphere in which the characters were immersed.

description: Upper bounds on time-averaged heat transport are obtained for an eight-mode Galerkin truncation of Rayleigh's 1916 model of natural thermal convection. Bounds for the ODE model---an extension of Lorenz's three-ODE system---are derived by constructing auxiliary functions that satisfy sufficient conditions wherein certain polynomial expressions must be nonnegative. Such conditions are enforced by requiring the polynomial expressions to admit sum-of-squares representations, allowing the resulting bounds to be minimized using semidefinite programming. Sharp or nearly sharp bounds on mean heat transport are computed numerically for numerous values of the model parameters: the Rayleigh and Prandtl numbers and the domain aspect ratio. In all cases where the Rayleigh number is small enough for the ODE model to be quantitatively close to the PDE model, mean heat transport is maximized by steady states. In some cases at larger Rayleigh number, time-periodic states maximize heat transport in the truncated model. Analytical parameter-dependent bounds are derived using quadratic auxiliary functions, and they are sharp for sufficiently small Rayleigh numbers.

description: This study explores the challenges faced by Nigerian postgraduate students in the UK, focusing on culture shock's impact on communication and adaptation. Addressing a gap in literature, it examines the communication techniques used by these students to navigate cultural differences. Anchored in Communication Accommodation Theory (CAT) and Social Identity Theory, the study analyses how students adjust their communication styles and how group identity influences adaptation. Utilising a survey research design, data from 381 Nigerian postgraduate students reveal various communication strategies, such as speaking clearly and embracing feedback, to overcome barriers. The study also maps the emotional stages of adaptation using Oberg's U-Curve Theory. A survey research design was adopted for this study. The population of this study was made up of Nigerian postgraduate students in Scotland, United Kingdom. According to the Higher Education Statistics Agency (2023), the number of Nigerian postgraduate students in the United Kingdom between the year 2017/2018 through to 2021/2022 is 51,815. Keyton’s formula for sample size determination was used to and the sample size of this study was 381. The snowball sampling was used in different stages. Data were gathered using the copies of the questionnaire which were administered on the respondents virtually. Quantitative data analysis was adopted in this study such as the Statistical Package for the Social Sciences (SPSS) and percentages. The findings have significant implications for educational institutions aiming to support international students. By enhancing communication skills and cultural awareness, institutions can better facilitate the integration and academic success of Nigerian postgraduate students. This research recommended that

description: A new candidate for the gamma-ray bursts central engine is proposed: if in some energetic cosmic event a macroscopic amount of bubbles of the disoriented chiral condensate can be formed, then their subsequent decays will produce a relativistic fireball without the baryon loading problem. The neutron star to strange star transition is considered as a candidate example of such cosmic event.

description: Inappropriate use of phosphorus and nitrogen fertilizers has imposed irreparable damage to plant growth and productivity. Urea doped hydroxyapatite nanoparticles (Ur@HANP) was designed for controlled-release formulation for crop improvement. The main objective of the present work was to synthesize and evaluate the functioning of Ur@HANP on rice seed germination and transport of nano-nutrients in soil media. HANP was synthesized using sol–gel technique and urea was loaded into it for monitoring rice seeds’ physiological and biochemical activities under controlled laboratory condition. Seedling growth (5.99217 ± 0.156), fresh weight (13.8 ± 0.5) and dry weight (1.6 ± 0.5) were enhanced in Ur@HANP treatment compared to control. Both HANP and Ur@HANP was also tested in sand columns and agricultural soil to understand the retention capacity of plant nutrients in sand and interaction with soil colloids, where Ur@HANP showed almost twofold efficiency than conventional P and N fertilizers. Even at a higher dose of 1 M, it did not impart any kind of toxicity symptoms. Almost twofold increase in α-amylase and starch content in Ur@HANP could be the reason for such response. We anticipate Ur@HANP could be a suitable alternative for N and P fertilizers in the development of eco-friendly sustainable agriculture.

description: We introduce a dynamical blockade phenomenon occurring in a nonlinear bosonic mode induced by a combination of continuous and pulsed excitations. We find that the underlying mechanism for the blockade is general, enhancing antibunching in the strongly nonlinear regime and inducing it in the weakly nonlinear regime, without fine-tuning the system parameters. Moreover, this mechanism shows advantages over existing blockade mechanisms and is suitable for implementation in a wide variety of systems due to its simplicity and universality.
