AbstractIdeally, discussions on the One Health policy should bring together actors from several sectors. This was the case at the conference organised by the One Health European Joint Programme (One Health EJP) “Collaborating to face future One Health challenges in Europe”, which took place from the 19 to the 21 June 2023 in Brussels, Belgium. Here we report on the discussions and interactions that occurred among lead European One Health stakeholders from the animal health, public health, wider environmental (including ecosystem health), and social sciences sectors, coming from the public and private sectors, and non-governmental organisations. The participants included policy makers, risk assessors, risk managers, experts from the academia, as well as representatives of national, European, and international organisations. The conference served two purposes. First, it highlighted the achievements of the One Health EJP on prevention, detection, and response to health threats. Second, it served as a forum to discuss current and future European One Health policies, analysing interactions across sectors, and setting the scene for the One Health policy agenda of tomorrow. In this article, we highlight the main messages and viewpoints of a wide range of European stakeholders on One Health and its future needs. Discussions covered topics such as policies of the European Commission, operationalisation of these policies through EU agencies, the broadening of the One Health concept to increasingly integrate sectors other than public health and animal health, and the role of the private sector in One Health initiatives. These dialogues gave insights into future One Health policies, providing information that integrate the publicly available policy documents, and aiming at shaping the European One Health approach in preparation for upcoming challenges.
Disappearance of rapid photoresponse in ultraviolet illumination of Ag–Sb–S films
Authors: Takagaki Y , Hanke M , Brandt O 
Published: February 2024

Abstract
The photoconduction in Ag0.5Sb0.5S films changes anomalously with the excitation energy. Although the usual instantaneous generation and recombination of photocarriers appear in the resistance of the films for the illumination at a wavelength of 633 nm, the photoresponse becomes slow with time scales of minutes when the illumination is performed at a wavelength of 280 nm. The rapid and slow phototransients are mixed for an intermediate excitation wavelength of 375 nm. In the simultaneous photoexcitation at multiple wavelengths, the response is complex instead of a superposition of the rapid and slow behaviors, indicating the mutual interaction in the photocarrier transport. The ultraviolet (UV) illumination can thereby block the rapid response that should be caused by the visible light. Moreover, the resistance can even increase during the illumination. Although the adsorption of molecules at the film surface plays an important role for the resistance, the anomalous properties are unaffected by the surface condition. They are thus suggested to be the bulk properties of the films, plausibly caused by the defects generated in the UV irradiation.
B-site disorder driven Griffiths-like phase and electrochemical behavior in Y2NiCrO6 double perovskite

Published: February 2024

Abstract
In this investigation, nanoparticles of B-site disordered Y2NiCrO6 (YNCO) double perovskite were synthesized by the facile sol–gel method to evaluate their magnetic and electrochemical properties. Their crystallographic structure is monoclinic and the average size of the particles is 79±16 nm. XPS analysis indicated a mixed oxidation states of B-site transition metals Ni2+/Ni3+ and Cr2+/Cr3+. The mixed valence states of Ni and Cr, along with the mixed magnetic phases of YNCO, constitute a signature of the B-site disorder. This antisite disorder contributed to the observation of a Griffiths-like phase arising from ferromagnetic short-range interactions above the magnetic transition up to the Griffiths temperature, T
G = 137 K. The synthesized YNCO double perovskite demonstrated a promising behavior as an electrode material for electrochemical supercapacitors. In a three-electrode system, it displayed a specific capacitance of 270 F g−1 at a current density of 0.5 A g−1. In a symmetric two-electrode system, YNCO exhibited a specific capacitance of 180 F g−1 at 0.5 A g−1, alongside an energy density of 6.25 Wh kg−1 at 250 W kg−1 power density. In both cases, we employed a mild 0.5 M neutral aqueous Na2SO4 solution as the electrolyte, in contrast to the typically employed corrosive and concentrated alkaline aqueous solution. The fascinating magnetic and charge storage properties of the B-site disordered YNCO double perovskite indicate its potential for use in spintronic devices and as efficient electrodes in symmetric hybrid supercapacitors.

Abstract
Design of the capacitive tactile sensor with ultra-high sensitivity and fast response/recovery times is critical to the advancement of wearable devices. However, achieving both fast response/recovery time and ultra-high sensitivity simultaneously is a huge challenge. In this work a simple and easy-to-prepare flexible capacitive tactile sensor is presented, using a biomimetic gray kangaroo structured dielectric layer of polydimethylsiloxane. By using finite element analysis to study the influences of various structures, the test result of the experimentally optimized tactile sensor showed ultra-high sensitivity (1.202 kPa−1), outstanding response and recovery time (60/85 ms), wide pressure range (0–220 kPa), and excellent stability. Finally, the tactile sensors are tested for practical applications, including robot tactile, human motion monitoring, and Morse code detection.
Estimation of geomagnetic components under unknown interferences for drilling tools

Published: February 2024

Abstract
The geomagnetic components measurement directly influences the azimuth and magnetic Toolface of downhole drilling tools. Accurate estimation of the geomagnetic components is crucial for wellbore trajectory control. However, the unknown magnetic interferences caused by ferromagnetic drilling tools introduce significant errors in the estimation of the geomagnetic components. Firstly, this paper considers the constraint of a constant total magnetic field value and introduces the unknown axial interferences of the drilling tools as a new state. At the same time, parameter uncertainties and radial interferences within the drilling tools are regarded as unknown but bounded, leading to the establishment of a linear time-varying system model for the measurement system. Then, a state estimation method based on the Zonotopic Kalman filter (ZKF) is proposed for geomagnetic components and attitude measurements. The simulation results indicate that, compared to the ZKF method without considering nonlinear constraints, the method proposed in this paper effectively separates the axial interference of the geomagnetic components from the drilling tools during dynamic measurements. The root mean square errors of the estimated three-axis geomagnetic components are reduced to 0.0249 Gauss, 0.0082 Gauss, and 0.0148 Gauss, resulting in improvements in accuracy of 96.06%, 28.6%, and 14.1%, respectively. Furthermore, the root mean square errors of the gravity Toolface, magnetic Toolface, and azimuth estimation decreased to 1.8296°, 1.8294°, and 3.2898°, leading to enhancements in accuracy of 9.61%, 9.71%, and 96.37%, respectively. Finally, experimental validation confirms the effectiveness of the proposed method, providing a reference basis for dynamic measurement while drilling.

Published: February 2024

Abstract
CoCrFeMnNi high-entropy alloy (HEA) has a high degree of thermodynamic stability and excellent ductility, making it a crucial structural material. However, the plastic deformation and microstructural behavior of gradient grain structured CoCrFeMnNi HEA under cutting remain unclear. In this study, the machining properties of gradient nanostructured CoCrFeMnNi HEA under conventional cutting were investigated by molecular dynamics simulation. The results displayed that the small grain gradient samples exhibited grain size softening. The shear angle and cutting ratio increased with the increase in the grain gradient. The grain boundaries of the low grain gradient samples were damaged and slid during the cutting process. Moreover, the dislocation density increased with the increasing grain gradient. The multi-dislocation nodes and the Lomer–Cottrell junction were produced in the grain coarsening gradient samples, contributing to work hardening. The cutting forces from low to high cutting velocities were 136.70, 147.91, 165.82, and 164.79 nN, which confirmed that the cutting forces increased with increased cutting velocity. This work elucidated the cutting mechanism of the nanostructured CoCrFeMnNi HEA and highlighted the influence of the gradient grain sizes.

Published: February 2024

Abstract
Lithium–sulfur (Li–S) batteries exhibit a huge potential in energy storage devices for the thrilling theoretical energy density (2600 Wh kg−1). Nevertheless, the serious shuttle effect rooted in polysulfides and retardative hysteresis reaction kinetics results in inferior cycling and rate performances of Li–S batteries, impeding commercial applications. In order to further promote the energy storage abilities of Li–S batteries, a unique binder-free sulfur carrier consisting of SnS2-modified multi-hole carbon nanofibers (SnS2-MHCNFs) has been constructed, where MHCNFs can offer abundant space to accommodate high-level sulfur and SnS2 can promote the adsorption and catalyst capability of polysulfides, synergistically promoting the lithium-ion storage performances of Li–S batteries. After sulfur loading (SnS2-MHCNFs@S), the material was directly applied as a cathode electrode of the Li–S battery. The SnS2-MHCNFs@S electrode maintained a good discharge capacity of 921 mAh g−1 after 150 cycles when the current density was 0.1 C (1 C = 1675 mA g−1), outdistancing the MHCNFs@S (629 mAh g−1) and CNFs@S (249 mAh g−1) electrodes. Meanwhile, the SnS2-MHCNFs@S electrode still exhibited a discharge capacity of 444 mAh g−1 at 2 C. The good performance of SnS2-MHCNFs@S electrode indicates that combining multihole structure designation and polar material modification are highly effective methods to boost the performances of Li–S batteries.
100 MeV protons from nanostructured hemispherical target using PIC simulations
Authors: Choudhury Jubaraj , Bhagawati Ankita , Sarma Jyotirup , Das Nilakshi 
Published: February 2024

Abstract
The improvement of laser-driven proton energy with the use of nano-structured hemispherical targets of 100 nm thickness over conventional flat foil has been reported in this work. The curvature of the target is found to result in focussed particle density at the center of the hemispherical target followed by emergence of energetic ions due to combined action of sheath electric field and ambipolar expansion. The presence of nano-rods on the curved hemispherical target further increases the laser energy absorption by the electrons, thus resulting in increase in the maximum proton energy. Use of hemispherical target embedded with nanorods is possibly reported here for the first time that may generate protons with energy 92 MeV by using linearly polarised laser of intensity 1021 W cm−2 and pulse duration of 30 fs. At this laser intensity, the energy gain by the protons is much higher compared to the conventional flat foil targets. The maximum proton energy can be increased further to 103 MeV by using truncated hemispherical target of similar parameter.

), where γ
0 represents the coefficient of static friction and µ is the scaling index. Through analytical and numerical results, we construct a diffusion phase diagram that encompasses different regimes upon variations in parameters γ
0 and µ: normal diffusion; superdiffusion; and hyperdiffusion. These transitions occur because the induced weaker friction enhances the diffusion. With a decrease in the scaling index, we find that the γ
0-dependent exponent of diffusion converges towards the experimental findings for ultracold 87Rb atoms because the strong effective friction arises. The discrepancies between the fractional Lévy kinetics and the experimental findings may be potentially reconciled. We believe that these findings are helpful for analyzing experimental observations of cold atoms diffusing in optical lattices.
Short study on mechanism of morphology change of γ′ precipitates in IN718 Plus
Authors: Duan Lingjie 
Published: February 2024

Abstract

γ′ Ni3Al phase (L12 structure) strengthened superalloy has become an important strengthening phase in Ni based superalloys because of its excellent high-temperature service performance, and has been widely used. The process of γ′ phase precipitation has also received a lot of attention and research. However, most studies focused on its growth rate. There were few studies on the morphology transformation of γ′ phase, and the morphology transformation process is complex. The mechanism of γ′ phase transformation process was systematically analyzed in this paper. Firstly, through molecular dynamics calculation, the most stable morphology of the γ′ phase in the nickel matrix was obtained under ideal conditions. The stability of spherical precipitates is higher than that of cubic precipitates. When the temperature is greater than 800 K, the stability is more obvious.Then through the micro EDS analysis of the γ′ phase in the morphology transformation process, it was shown that the soft impingement phenomenon exists in the nickel base alloy with high γ′ phase volume fraction. Further, by the derivation of the formula of solid-state phase transformation, it was found that the growth rate of precipitate is directly proportional to the concentration gradient of Al in the matrix at the interface, while increases with the rising of the Al concentration in the matrix at the interface. Finally, the way and mechanism of soft impingement affecting the morphology transformation were analyzed. The precipitates formed by soft impingement are nearly cubic precipitates with rounded edges and corners.
Bipolar electron waveguides in two-dimensional materials with tilted Dirac cones
Authors: Hartmann R R , Portnoi M E 
Published: February 2024

Abstract
We show that the (2+1)-dimensional massless Dirac equation, which includes a tilt term, can be reduced to the biconfluent Heun equation for a broad range of scalar confining potentials, including the well-known Morse potential. Applying these solutions, we investigate a bipolar electron waveguide in 8–Pmmn borophene, formed by a well and barrier, both described by the Morse potential. We demonstrate that the ability of two-dimensional materials with tilted Dirac cones to localize electrons in both a barrier and a well can be harnessed to create pseudogaps in their electronic spectrum. These pseudogaps can be tuned through varying the applied top-gate voltage. Potential opto-valleytronic and terahertz applications are discussed.

Published: February 2024

Abstract
We adopt the genetic algorithm to fit the potential energy curve for B1Π state of 85Rb133Cs molecule based on the data of rovibrational energy levels, which were observed previously by Fourier-transform spectroscopy and photoassociation spectroscopy. We explore the effect of different hyperparameter settings on the evolutionary process and final results to optimise the performance of the algorithm. Finally, the fitting procedure can reproduce the rovibrational levels with an error less than 0.06 cm−1 compared to the experimental data.
Generation multi-scroll chaotic attractors using composite sine function and its application in image encryption
Authors: Ding Pengfei , Li Ke , Wang Zixuan 
Published: February 2024

Abstract
In this paper, a composite sine function is proposed and applied in a chaotic system, which is capable of generating definite number of chaotic attractors. The proposed composite sine function possesses infinite breakpoints, but it can produce a fixed number of scrolls by adjusting its parameters. Compared to other chaotic systems with multiple scrolls chaotic attractors, the realization circuit of the chaotic system with compound sine function allows obtaining different numbers of scrolls by adjusting only one resistance value. As a result, the circuit structure remains unchanged despite variations in the number of scrolls. Various analytical methods are applied to study the dynamical behaviors of the proposed chaotic system, including Lyapunov exponent, equilibrium point, bifurcation diagram, phase diagram, spectral entropy and C0-algorithm. Furthermore, based on the analysis of dynamical characteristics, the electronic circuits of the proposed system are given on Multisim circuit simulation software, and the multi-scroll chaotic attractors exhibit consistency with the numerical simulation results. Finally, we incorporated the proposed chaotic system into a Deoxyribonucleic acid coding algorithm for image encryption, and this method exhibits excellent encryption efficiency and high level of security.
Small resonant magnetic perturbations result in three-dimensional material transport in the fusion plasma edge
Authors: Navarro Marcos , Romazanov Juri , Kirschner Andreas , Van Blarcum Jonathan , Hinson Edward , Abrams Tyler , Schmitz Oliver 
Published: February 2024

Abstract
Erosion patterns in a 3D magnetic topology are significantly altered when compared to an axisymmetric scenario due to differences in the impurity transport in a plasma environment. When resonant magnetic perturbations are applied in L-Mode discharges, eroded impurities can buildup in regions where an axisymmetric plasma would otherwise lead to zones of net erosion across the full toroidal length of the divertor. The reduction on the local and integrated erosion observed across a parametric study of the anomalous diffusion and impurity content in a plasma, can lead to the extension of divertor lifetimes in low power scenarios when 3D fields are applied. By contrast, in axisymmetric scenarios, most of the carbon eroded from the divertor are carried away to the far scrape-off layer.

Published: February 2024

Abstract
Patterned surfaces can be designed and engineered to control friction and wear resistance in various applications. In the present work, a comparative analysis of two contrasting manufacturing processes for surface texturing of polyamide, namely 3D printing by fused filament fabrication (FFF) and CNC micromachining (micro CNC) as additive and subtractive manufacturing techniques respectively was carried out. The analysis included the evaluation of the topography, roughness, mechanical properties, and tribological performance of the texturized surfaces. Both manufacturing routes were suitable for fabricating deterministic surfaces, being the micro CNC method the one that provided better repeatability and surface finishing as well as higher hardness. These factors influenced the tribological behavior of the polyamide when in contact with AISI 304 stainless steel. The effects of size, distribution and height of the texture elements and the manufacturing technique on the Coefficient of Friction (COF) were also discussed.

Published: February 2024

Abstract

Objective. This study aims to investigate the biological effectiveness of Spread-Out Bragg-Peak (SOBP) proton beams with initial kinetic energies 50–250 MeV at different depths in water using TOPAS Monte Carlo code. Approach. The study modelled SOBP proton beams using TOPAS time feature. Various LET-based models and Repair-Misrepair-Fixation model were employed to calculate Relative Biological Effectiveness (RBE) for V79 cell lines at different on-axis depths based on TOPAS. Microdosimetric Kinetic Model and biological weighting function-based models, which utilize microdosimetric distributions, were also used to estimate the RBE. A phase-space-based method was adopted for calculating microdosimetric distributions. Main results. The trend of variation of RBE with depth is similar in all the RBE models, but the absolute RBE values vary based on the calculation models. RBE sharply increases at the distal edge of SOBP proton beams. In the entrance region of all the proton beams, RBE values at 4 Gy i.e. RBE(4 Gy) resulting from different models are in the range of 1.04–1.07, comparable to clinically used generic RBE of 1.1. Moving from the proximal to distal end of the SOBP, RBE(4 Gy) is in the range of 1.15–1.33, 1.13–1.21, 1.11–1.17, 1.13–1.18 and 1.17–1.21, respectively for 50, 100, 150, 200 and 250 MeV SOBP beams, whereas at the distal dose fall-off region, these values are 1.68, 1.53, 1.44, 1.42 and 1.40, respectively. Significance. The study emphasises application of depth-, dose- and energy- dependent RBE values in clinical application of proton beams.
