Recommandations nutritionnelles lors de diabète sucré chez le chien et le chat
Authors: Blanchard Géraldine 
Published: June 2024

La gestion du diabète nécessite de comprendre que le glucose issu de la digestion des glucides alimentaires passe dans le sang, ne peut entrer dans les cellules par manque d’insuline, et augmente la glycémie du diabétique.
Le chien et le chat sont capables de néoglucogenèse cellulaire à partir d’acides aminés. En cas de diabète, on peut diminuer l’hyperglycémie par une alimentation la plus pauvre possible en glucides et riche en protéines.
Chez le chat, cela peut même permettre le retour à l’euglycémie avec arrêt de l’insuline.
Une alimentation sans glucides est nécessairement humide (ration ménagère ou pâtée sans féculent), les croquettes nécessitant toutes de l’amidon pour leur fabrication.
Après une transition progressive pour faire accepter le changement, l’alimentation humide sera donnée en 4 repas chez le chat (même avec 1 seule injection d’insuline par jour), et en 2 repas chez le chien (chacun avec une injection d’insuline).
La stabilité de l’alimentation du diabétique est indispensable pour espérer une dose d’insuline identique chaque jour. Comme la glycémie dépend de la composition en macronutriments de l’alimentation, il faudra suivre la glycémie sur 24 heures une fois l’alimentation stable depuis quelques jours.
En cas de pathologie multiple nécessitant un ajustement nutritionnel, une ration sur mesure peut être calculée, qui prenne en compte les contraintes de toutes les maladies en présence.
Visible-Light-Mediated gem-Difunctionalization of Diazo Compounds with Vinyl Sulfoxonium Ylides and Thiols
Authors: Vaitla Janakiram , Bhardwaj Srashti , Sen Raju , Adhikari Payel 
Published: June 2024

AbstractA visible-light-induced multicomponent reaction of vinyl sulfoxonium ylide, thiol, and diazo ester to generate tertiary sulfide is described. The present diastereoselective gem-difunctionalization of the diazo ester can be achieved under mild conditions, as it does not require any additives, catalysts, or transition metals and is tolerant of air and moisture. Due to more nucleophilicity, vinyl sulfoxonium ylide undergoes S–H insertion with thiols to generate an allyl sulfide intermediate. Simultaneously, diazo ester undergoes photolysis to generate a carbene intermediate. Subsequently, the coupling of carbene and allyl sulfide intermediates generates sulfonium ylide, which undergoes Doyle–Kirmse rearrangement to generate tertiary sulfide scaffolds.
Sociocultural dynamics of learners’ emotions in a Chinese English-medium instruction context
Authors: Sun Youzhi 
Published: June 2024

Abstract
Drawing on Activity Theory, this study is an attempt to explore and explicate learners’ emotions in a Chinese
English-medium instruction (EMI) context. This paper detailed two cases of university learners to address two issues: how the
relationship between EMI learners and their perceived sociocultural contexts shapes their foreign language enjoyment and anxiety
and how the factors affecting the two emotions can be explained from an Activity Theory (AT) perspective. Qualitative content
analysis was performed on data collected from in-depth, face-to-face interviews and journals. The findings illustrated that a
diversity of sociocultural factors, ranging from the object of learning to the rules of learning, could influence learners’
emotions. Contradictions between these factors also influenced EMI learners’ two emotions. This study could inform educational
language policy and the development of EMI curricula and pedagogy.
Evidence for phase transitions in CoFe2O4 and NiCo2O4 thin films in temperature-dependent X-ray photoelectron spectroscopy
Authors: Subedi Arjun , Yang Detian , Xu Xiaoshan , Dowben Peter A 
Published: June 2024

Abstract
X-ray photoelectron spectroscopy (XPS) shows that dramatic changes in the core level binding energies can provide strong indications of transitions between more dielectric and more metallic CoFe2O4 and NiCo2O4 thin films. These significant variations in the XPS core level binding energies are possible with a combination of annealing and oxygen exposure; however, the behaviors of the CoFe2O4 and NiCo2O4 thin films are very different. The XPS Co and Fe 2p
3/2 core levels for the CoFe2O4 thin film at room temperature show large photovoltaic surface charging, leading to binding energy shifts, characteristic of a highly dielectric (or insulating) surface at room temperature. The photovoltaic charging, observed in the XPS binding energies of the Co and Fe 2p
3/2 core levels, decreases with increasing temperature. The XPS core level binding energies of CoFe2O4 thin film saturated at lower apparent binding energies above 455 K. This result shows that the prepared CoFe2O4 thin film can be dielectric at room temperature but become more metallic at elevated temperatures. The dielectric nature of the CoFe2O4 thin film was restored only when the film was annealed in sufficient oxygen, indicating that oxygen vacancies play an important role in the transition of the film from dielectric (or insulating) to metallic. In contrast, the XPS studies of initially metallic NiCo2O4 thin film demonstrated that annealing NiCo2O4 thin film led to a more dielectric or insulating film. The original more metallic character of the NiCo2O4 film was restored when the NiCo2O4 was annealed in sufficient oxygen. Effective activation energies are estimated for the carriers from a modified Arrhenius-type model applied to the core level binding energy changes of the CoFe2O4 and NiCo2O4 thin films, as a function of temperature. The origin of the carriers, however, is not uniquely identified. This work illustrates routes to regulate the surface metal-to-insulator transition of dielectric oxides, especially in the case of insulating NiCo2O4 thin film that can undergo reversible metal-to-insulator transition with temperature.

Published: June 2024

Abstract
Metasurface technology has attracted widespread attention, owing to its remarkable capability to control electromagnetic properties. In this paper, we design a reconfigurable reflective metasurface array operating at 5 GHz for beam generation and scanning based on coding metasurface. Field programmable gate array (FPGA) is equipped for switching the states of PIN (positive-intrinsic-negative) diodes loaded on the metasurface in real-time, resulting in a 180° phase difference. To obtain multi-beam radiation and high-accuracy beam steering, the coding sequence to produce the target radiation pattern is calculated by an algorithm program. We design the fitness function of a genetic algorithm (GA) to optimize the sequence corresponding to the target directions. The simulation result shows that with the accuracy of 1°, the proposed metasurface is capable of generating multi-beam and scanning two-dimensional beams within the 50° range. Further, we fabricate and measure a prototype sample of 15 × 15 elements, which is verified feasible by comparing the measured result and the simulation. This work demonstrates the great potential of applying this reflective metasurface to wireless communication or radar.
Modelling nanomagnet vertex dynamics through Coulomb charges
Authors: Slöetjes Samuel D , Grassi Matías P , Kapaklis Vassilios 
Published: June 2024

Abstract
We investigate the magnetization dynamics in nanomagnet vertices often found in artificial spin ices. Our analysis involves creating a simplified model that depicts edge magnetization using magnetic charges. We utilize the model to explore the energy landscape, its associated curvatures, and the fundamental modes. Our study uncovers specific magnonic regimes and transitions between magnetization states, marked by zero-modes, which can be understood within the framework of Landau theory. To verify our model, we compare it with micromagnetic simulations, demonstrating a noteworthy agreement.
Flat-bands in translated and twisted bilayer Penrose quasicrystals
Authors: Díaz-Reynoso U A , Huipe-Domratcheva E , Navarro O 
Published: June 2024

Abstract
Correlated phases in Moiré materials together with the flat-bands in twisted systems play a central role to explain superconductivity in the new twisted bilayer graphene. In this paper, flat-bands are shown to exist in both translated and twisted bilayer of quasicrystals. Such flat-bands arise for different displacements and twisting angles of two-coupled Penrose lattices where Moiré patterns are also shown. Moiré patterns analyzed in this work have at least two inverted worms showing an interference pattern going along the five-fold axes of the pentagon. In order to analyze the behavior of the flat band, our study has been done for fixed interference worm directions but increasing the worm interference density, and for fixed worm interference density but increasing the number of worm directions. In case of rotations, the Moiré patterns that occurs for special angles such as π/5, 2π/5, 3π/5, 4π/5 and π are discussed in detail because they clearly show flat-bands along with quasicrystalline electronic states at the Fermi level.
Open-circuit voltage deficits in Tin-based perovskite solar cells
Authors: Ma Xue , Wang Ning 
Published: June 2024

Abstract
The power conversion efficiency of Pb-based single-junction perovskite solar cells (PSCs) has surpassed 26%; however, the biocompatibility concerns associated with Pb pose threats to both the environment and living organisms. Consequently, the development of Pb-free PSCs is imperative. Among the various alternatives to Pb-based PSCs, Sn-based PSCs have exhibited outstanding optoelectronic properties, showing great potential for large-scale manufacturing and commercialization. Nevertheless, there remains a significant efficiency gap between Sn-based and Pb-based PSCs. The disparity primarily stems from substantial open-circuit voltage (V
OC) deficits in Sn-based PSCs, typically ranging from 0.4 to 0.6 V. The main reason of V
OC deficits is severe non-radiative recombination losses, which are caused by the uncontrolled crystallization kinetics of Sn halide perovskites and the spontaneous oxidation of Sn2+. This review summarizes the reasons for V
OC deficits in Sn-based PSCs, and the corresponding strategies to mitigate these issues. Additionally, it outlines the persistent challenges and future prospects for Sn-based PSCs, providing guidance to assist researchers in developing more efficient and stable Sn-based perovskites.
Electronic instability in pressured black phosphorus under strong magnetic field
Authors: Wang Zhong-Yi , Liu Da-Yong , Zou Liang-Jian 
Published: June 2024

Abstract
In this paper, we have systematically studied the electronic instability of pressured black phosphorous (BP) under strong magnetic field. We first present an effective model Hamiltonian for pressured BP near the Lifshitz point. Then we show that when the magnetic field exceeds a critical value, the nodal-line semimetal (NLSM) state of BP with a small band overlap re-enters the semiconductive phase by re-opening a small gap. This results in a narrow-bandgap semiconductor with a partially flat valence band edge. Moreover, we demonstrate that above this critical magnetic field, two possible instabilities, i.e. charge density wave phase and excitonic insulator (EI) phase, are predicted as the ground state for high and low doping concentrations, respectively. By comparing our results with the experiment (Sun et al 2018 Sci. Bull.
63 1539), we suggest that the field-induced instability observed experimentally corresponds to an EI. Furthermore, we propose that the semimetallic BP under pressure with small band overlaps may provide a good platform to study the magneto-exciton insulators. Our findings bring the first insight into the electronic instability of topological NLSM in the quantum limit.

Abstract
The electromagnetic field enhancement mechanisms leading to surface-enhanced Raman scattering (SERS) of R6G molecules near Ti3C2T
x
MXene flakes of different shapes and sizes are analyzed theoretically in this paper. In COMSOL simulations for the enhancement factor (EF) of SERS, the dye molecule is modeled as a small sphere with polarizability spectrum based on experimental data. It is demonstrated, for the first time, that in the wavelength range of

500

nm

–

1000

nm

, the enhancement of Raman signals is largely conditioned by quadrupole surface plasmon (QSP) oscillations that induce a strong polarization of the MXene substrate. We show that the vis-NIR spectral range quadrupole SP resonances are strengthened due to interband transitions (IBTs), which provide EF values of the order of 105–107 in agreement with experimental data. The weak sensitivity of the EF to the shape and size of MXene nanoparticles (NPs) is interpreted as a consequence of the low dependence of the absorption cross-section of QSP oscillations and IBT on the geometry of the flakes. This reveals a new feature: the independence of EF on the geometry of MXene substrates, which allows to avoid the monitoring of the shape and size of flakes during their synthesis. Thus, MXene flakes can be advantageous for the easy manufacturing of universal substrates for SERS applications. The electromagnetic SERS enhancement is determined by the ‘lightning rod’ and ‘hot-spot’ effects due to the partial overlapping of the absorption spectrum of the R6G molecule with these MXene resonances.

Turbulence link to L-mode, I-mode, and H-mode confinement in the DIII-D tokamak
Authors: Chen J. , Brower D.L. , McClenaghan J. , Yan Z. , Hubbard A.E. , Groebner R. 
Published: June 2024

Abstract
Understanding the physics of low-confinement (L-), improved-confinement (I-), and high-confinement (H-) modes is critical for fusion reactors. The finding herein reports observations of two types of turbulence coexisting near the L-mode edge, one magnetohydrodynamic (MHD)-like and another micro-tearing mode (MTM)-like, linked to the H-mode and I-mode confinement in the DIII-D tokamak. Ion-scale magnetic and density turbulence is measured using a Faraday-effect radial-interferometer-polarimeter and beam-emission-spectroscopy (BES). Broadband turbulence spectra of up to ∼600 kHz are observed in two discharges where transitions between L-mode, I-mode, and H-mode occurs. Turbulence is found to be inversely correlated with confinement, meaning lower turbulence power at higher confinement. Distinctively, the high-frequency (HF, >∼100 kHz) magnetic turbulence power changes by the most (55%) during transitions primarily involving energy confinement change, whereas the low-frequency (LF, <∼100 kHz) magnetic and density turbulence power changes by the most (80%) during transitions primarily involving particle confinement change. The LF turbulence amplitude oscillates with and leads to deuterium-alpha emission oscillations before an H-mode. These results imply that HF turbulence mainly affects energy confinement whereas LF turbulence can affect particle confinement. The magnetic and density turbulence exhibits coherence up to 0.6 and cross-phase magnitude close to

π

in most cases, suggesting they have a common origin in both the LF and HF ranges. BES suggests that LF turbulence resides at the edge (

ρ
=
0.95

) and HF turbulence can be at the outer core (

ρ
=
0.8

) or edge (

ρ
=
0.95

). Comparisons of measurements, theory, and gyrokinetic simulations suggest that HF turbulence is MTM-like in all cases, whereas LF turbulence is more consistent with MHD-like modes and the exact instability might change during transitions—except that a drift-wave origin is possible in a low collisionality H-mode. These results suggest that the H-mode involves suppressed MHD-like turbulence, whereas the I-mode mitigates MTM-like turbulence along with largely unchanged MHD-like turbulence.
Molecular dynamics simulations and analyzation of Cu deposited on stainless steel substrate surfaces
Authors: Ying Wang , Zewei Yuan , Meiling Tang , Jingting Sun , Yan He 
Published: June 2024

Abstract
Copper (Cu) is used in integrated circuits and microdevices and has the potential to replace aluminum alloys due to its low resistivity, strong electromigration properties, and affordability. However, a significant factor that influences the performance of devices at the micro and nano scales is the surface roughness of the deposits. LAMMPS software is employed to simulate the deposition Cu on an ideal state for a stainless-steel substrate. The deposition process and deformation behavior of Cu on the surface and the roughness of the deposition surface are analyzed. Taking the deposition process of Cu atoms as an object, the effects of different atomic numbers, different temperatures, different velocities, and different heights on the surface roughness of the deposits were investigated. The atomic structure composition of the deposition velocity is analyzed, and the radial distribution function is analyzed to reveal the microscopic mechanism of action. The results of the theoretical deposition and analysis show that the surface roughness increases with the number of atoms deposited and decreases with increasing substrate temperature. The surface roughness first decreases and then, after some fluctuation, stays constant at a particular level with increasing velocity. Additionally, as the deposition height increases, the surface roughness reduces. There is a nonlinear relationship between the various components and the deposited surface roughness. The surface quality of deposits can be improved during the deposition process by optimizing the deposition parameters of deposition atoms, substrate temperature, deposition velocity, and deposition height.
A comparative evaluation of polymeric materials as tissue equivalent phantoms in diagnostic radiology
Authors: Şirin Erdi , Altinsoy Nesrin 
Published: June 2024

Abstract
In this study tissue equivalency of the polymeric materials was investigated by comparing with ICRP 110 Male Adult Computational Phantom tissues. For this purpose, radiological properties of polyamide (PA), high density polyethylene (HDPE), ultra-high molecular weight polyethylene (UHMWPE), polypropylene (PP), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), polyoxymethylene (POM) and polyurethane foam (PU FOAM) were evaluated in the diagnostic energy range (15–150 keV). The radiological properties of the materials and ICRP 110 Male and Female Adult Computational Phantom tissues were calculated with Phy-X/PSD software. No major differences were seen except for sex-specific organs, and comparisons were made using an adult male phantom. To confirm the results experimentally, a chest phantom was designed with the polymeric materials. The phantom was scanned by Siemens SOMATOM Edge CT device with tube voltage of 120 kVp and Hounsfield Unit (HU) values were measured. In addition, HU values were calculated using theoretical relationships and significant agreement was obtained between measured and calculated HUs. It was determined that PA, PP, UHMWPE and HDPE were equivalent to muscle and adipose tissue, PVC and PTFE were equivalent to mineral bone, PET and POM were equivalent to spongiosa bone and PU FOAM was equivalent to lung tissue.
The Origins of British Port Chaplaincy
Authors: Sampson Helen , Turgo Nelson , Cadge Wendy , Gilliat-Ray Sophie 
Published: June 2024

AbstractThis chapter outlines the historical development of some of the major faith-based charities that provide and support port chaplaincy in UK ports today. It focuses on two organizations that have played a major role in delivering port chaplaincy services—the Stella Maris, which, before 2020, was known as Apostleship of the Sea (AoS), and the Mission to Seafarers (MtS). Using archived documentation and secondary sources, the chapter describes the ways in which port chaplaincy services have been developed in the United Kingdom, the reasons for their development and the transformation of provision over time.
Investigating the link between antipsychotic use and post-stroke infections in older people: multi-centre propensity score analysis
Authors: Park Hae-Yeon , Jung Moa , Park Geun-Young , Lee Jong In , Kim Youngkook , Kim Yeo Hyung , Lim Seong Hoon , Yoo Yeun Jie , Im Sun 
Published: June 2024

Abstract

Background
The risk of stroke increases with age, and although previous reports have suggested that infection risk may increase with antipsychotic use, relevant studies after stroke are scarce. We aimed to investigate whether antipsychotics increase post-stroke infection risk in the acute stroke period.

Methods
This propensity score matching study included adults diagnosed with first-ever stroke between 2011 and 2020 at five university hospitals. In-hospital antipsychotic exposure was defined as any administration during hospitalisation for stroke. The primary outcome was post-stroke infection after the first 2 days of hospitalisation, and the secondary outcome was the presence of pneumonia, bacteraemia and/or bacteriuria.

Result
Among 23,885 first-ever stroke patients, 2,773 antipsychotic users (age 71.6 ± 12.4, male 54.6%) and 2,773 non-users (age 71.2 ± 13.2, male 54.6%) were selected as matched cohorts. After adjusting for propensity score, antipsychotics were not associated with an increased risk of post-stroke infection (odds ratio 0.99, 95% confidence interval 0.87–1.14).

Conclusion
While our study did not find conclusive evidence linking antipsychotic medication to an increased risk of post-stroke infection, prescribing these medications should still be approached with prudence. Until further research can provide more definitive insights, clinicians should carefully weigh the potential infection risks when considering antipsychotic treatment during the acute stroke care period.
