Structure and evolution of a tidally heated star
Authors: Estrella-Trujillo D. , Arthur S. J. , Koenigsberger G. , Moreno E. 
Published: December 2022

Context. The shearing motion of tidal flows that are excited in non-equilibrium binary stars transform kinetic energy into heat via a process referred to as tidal heating.
Aims. We aim to explore the way tidal heating affects the stellar structure.
Methods. We used the TIDES code, which solves the equations of motion of the three-dimensional (3D) grid of volume elements that conform multiple layers of a rotating binary star to obtain an instantaneous value for the angular velocity, ω″, as a function of position in the presence of gravitational, centrifugal, Coriolis, gas pressure, and viscous forces. The released energy, Ė, was computed using a prescription for turbulent viscosity that depends on the instantaneous velocity gradients. The Ė values for each radius were injected into a MESA stellar structure calculation. The method is illustrated for a 1.0 + 0.8 M⊙ binary system, with an orbital period of P = 1.44 d and departures from synchronous rotation of 5% and 10%.
Results. Heated models have a larger radius and surface luminosity, a smaller surface convection zone, and lower nuclear reaction rates than the equivalent standard stellar models, and their evolutionary tracks extend to higher temperatures. The magnitude of these effects depends on the amount of injected energy, which, for a fixed set of stellar, rotation and orbital parameters, depends on the perturbed star’s density structure and turbulent viscosity.
Conclusions. Tidal heating offers a possible alternative for describing phenomena such as bloated or overluminous binary components, age discrepancies, and aspherical mass ejection, as well as the extended main sequence turnoff in clusters. However, establishing its actual role requires 3D stellar structure models commensurate with the nonspherically symmetric properties of tidal perturbations.

Context. The recent and exquisite astrometric, photometric, and radial velocity measurements of the Gaia mission resulted in a substantial advancement of the determination of the orbits for old star clusters, including the oldest Milky Way globular clusters (MW GCs).
Aims. The main goal of the present paper is to use the new Gaia data release 3 (DR3) and the VISTA Variables in the Via Láctea Extended Survey (VVVX) measurements to obtain the orbits for nearly a dozen new MW GC candidates that have been poorly studied or previously unexplored.
Methods. We use the Gaia DR3 and VVVX databases to identify bona fide MW GC candidates, namely VVV-CL160, Patchick 122, Patchick 125, Patchick 126, Kronberger 99, Kronberger 119, Kronberger 143, ESO 92-18, ESO 93-08, Gaia 2, and Ferrero 54. The relevant mean cluster physical parameters are derived (distances, Galactic coordinates, proper motions, radial velocities). We also measure accurate mean radial velocities for the GCs VVV-CL160 and Patchick 126 using observations acquired at the Gemini-South telescope with the Immersion GRating INfrared Spectrometer (IGRINS) high-resolution spectrograph. Orbits for each cluster are then computed using the GravPot16 model, assuming typical Galactic bar pattern speeds.
Results. We reconstruct the orbits for these 11 star clusters for the first time. These include star clusters with retrograde and prograde orbital motions, both in the Galactic bulge and disk. We obtain orbital properties for this sample, such as the mean time-variations of perigalactic and apogalactic distances, eccentricities, vertical excursions from the Galactic plane, and Z-components of the angular momentum.
Conclusions. Our main conclusion is that, based on the orbital parameters, Patchick 125 and Patchick 126 are genuine MW bulge or halo GCs; and Ferrero 54, Gaia 2, and Patchick 122 are MW disk GCs. In contrast, the orbits of Kronberger 99, Kronberger 119, Kronberger 143, ESO 92-18, and ESO 93-08 are more consistent with old MW disk open clusters, in agreement with previous results. VVV-CL160 falls very close to the Galactic centre, but reaches larger distances beyond the Solar orbit, and therefore its origin is still unclear.
Conductive polymer hydrogel-coated nanopipette sensor with tunable size
Authors: Li Lin , Zhou Feng , Xue Qiannan 
Published: December 2022

Nanopipette-based sensors are one of the most effective tools for detecting nanoparticles, bioparticles, and biomolecules. Quantitative analysis of nanoparticles with different shapes and electrical charges is achieved through measurement of the blockage currents that occur when particles pass through the nanopore. However, typical nanopipette sensors fabricated using a conventional needle-pulling method have a typical pore-diameter limitation of around 100 nm. Herein, we report a novel conductive hydrogel-composited nanopipette sensor with a tunable inner-pore diameter. This is made by electrodepositing poly(3,4-ethylenedioxythiophene) polystyrene sulfonate onto the surface of a nanopipette with a prefabricated sacrificial copper layer. Because of the presence of copper ions, the conductive polymer can stably adhere to the tip of the nanopipette to form a nanopore; when nanoparticles pass through the conductive nanopore, more distinct blocking events are observed. The size of the nanopore can be changed simply by adjusting the electrodeposition time. In this way, suitable nanopores can be obtained for highly sensitive screening of a series of particles with diameters of the order of tens of nanometers.
Giant spin Hall effect in half-Heusler alloy topological semimetal YPtBi grown at low temperature
Authors: Shirokura Takanori , Hai Pham Nam 
Published: December 2022

Half-Heusler alloy topological semimetal YPtBi is a promising candidate for an efficient spin source material having both large spin Hall angle θSH and high thermal stability. However, high-quality YPtBi thin films with low bulk carrier density are usually grown at 600 °C, which exceeds the limitation of 400 °C for back end of line (BEOL) process. Here, we investigate the crystallinity and spin Hall effect of YPtBi thin films grown at lower growth temperature down to 300 °C. Although both effective spin Hall angle and spin Hall conductivity degraded with lowering the growth temperature to 300 °C due to degradation of the interfacial spin transparency, they were recovered by reducing the sputtering Ar gas pressure. We achieved a giant θSH up to 7.8 and demonstrated efficient spin–orbit torque magnetization switching by ultralow current density of ∼105 A/cm2 in YPtBi grown at 300 °C with the Ar gas pressure of 1 Pa. Our results provide the recipe to achieve giant θSH in YPtBi grown at lower growth temperature suitable for BEOL process.
The temporality of commodified landscapes at events & local constructions of identity in Salzburg
Authors: Niehaus Konstantin 
Published: December 2022

Abstract
This paper presents a study of how temporary, fixed-term local semiotic landscapes in Salzburg, Austria,
contribute to a construction of local identity. For this purpose, two main events in the city’s calendar were investigated, the
Ruperti fair in the autumn and the Christmas market in the winter. I explore how and the extent to which semiotic resources such
as linguistic features index local pride and become commodified, i.e., utilized for economic gain. The indexicality can be
temporary or even volatile with some signs and creates an event-specific or non-event specific semiotic ‘register’
(enregisterment). The analysis follows two major commodifying practices, historicizing (in particular, the use of
blackletter) and localizing (use of non-standard Austro-Bavarian dialect), and employs a multimodal approach. A
qualitative analysis reveals how signs add to the temporary local authentication and discusses how LL research can benefit from
capturing event spaces and the temporality of signs.
Dimensionality reduction using local-global standard hypergraph embedding for rotor fault diagnosis
Authors: Yuan Jianhui , Zhao Rongzhen , Chen Pengfei , He Tianjing , Wei Kongyuan 
Published: December 2022

Abstract
The vibration signal contains a lot of state information, and its time domain, frequency domain, and time-frequency domain features are extracted to describe the rotor’s operational state in detail. However, multi-domain and multi-angle feature extraction can lead to information redundancy, causing the ‘dimensionality catastrophe’ problem, which also makes fault classification more difficult. Dimensionality reduction (DR) is a technique that can help with this issue, but the majority of current DR algorithms are based on a simple intrinsic structure. To accurately characterize the intrinsic structure of high-dimensional fault dataset, this study proposed a novel DR algorithm that considers local information, global information, and the hypergraph model, named local–global standard hypergraph embedding (LGSHE). LGSHE redefines the hypergraph weight matrix’s calculation formula and constructs the local intra-class standard hypergraph, local inter-class standard hypergraph, global intra-class standard hypergraph, and global inter-class standard hypergraph to characterize the fault data structure. LGSHE can accurately characterize the intrinsic structure of high-dimensional fault dataset and increase fault classification accuracy. The performance of LGSHE is validated on two different structures of double-span rotor experimental benches, and the results show that the algorithm can achieve good fault classification accuracy.
Coupled sn-cn, sn-dn, cn-dn Jacobi elliptic functions and solitons solutions in magneto-optic waveguides with quadratic-cubic nonlinearity
Authors: Yomba Emmanuel 
Published: December 2022

Abstract
The current paper is dedicated to the study of the propagation of progressive solitons in magneto-optical waveguides that carry the quartic-cubic nonlinearity described by a coupled system of of nonlinear Schrödinger equations. In this direction, we take the help of a modified F-expansion method which allows us to widen the class of solutions to these coupled equations and permit the propagation of different waves in the two channels. First of all, we constructed the solutions in terms of Jacobi elliptic functions in the forms of

After that, we obtained the progressive soliton solutions when these functions approached their limiting values with regards to the modulus of ellipticity. The progressive solutions include bright-dark soliton, bright-bright soliton, dark-dark soliton, bright-front soliton, dark-front soliton. In addition, we present the figures 1–6 which graphically exhibit the representative structures of each explicit solution for some special parameter values.
Gravitational wave background from vacuum and thermal fluctuations during axion-like inflation
Authors: Klose P. , Laine M. , Procacci S. 
Published: December 2022

Abstract
We revisit the framework of axion-like
inflation in view of the possibility
that the coupling of the inflaton to a non-Abelian topological charge
density could lead to the generation of a rapidly thermalizing heat bath.
Both dispersive (mass) and absorptive (friction)
effects are included. For phenomenologically
viable parameters, the system remains in a weak
regime of warm inflation (thermal friction ≪ Hubble rate).
For tensor perturbations we derive an interpolating formula
that incorporates both vacuum and thermal production.
The latter yields a model-independent frequency shape ∼ f

in the LISA window, whose coefficient allows to measure
the maximal shear viscosity of the thermal epoch. It is a challenge,
however, to find models where the coefficient is
large enough to be observable.
Relativistic models of anisotropic superdense star in the regime of Karmarkar’s condition
Authors: Parida Bikram Keshari , Majumder Shreya , Das Shyam , Chakraborty Koushik , Rahaman Farook 
Published: December 2022

Abstract
We obtained a new class of solutions for a relativistic anisotropic compact star by utilizing the Karmarkar embedding condition. To obtain the closed-form solution a suitable form of one of the gravitational potentials has been chosen to determine the other by analyzing the Karmarkar condition. The resulting solutions are found to be well-behaved and regular and could describe a compact stellar object. Considering the current estimated values of the mass and radius of the pulsar 4U1820 − 30 as input parameters, all the physically relevant parameters are shown to be well-behaved to a very good degree of accuracy.
Galaxy Interactions in Filaments and Sheets: Effects of the Large-scale Structures Versus the Local Density
Authors: Das Apashanka , Pandey Biswajit , Sarkar Suman 
Published: December 2022

Abstract
Major interactions are known to trigger star formation in galaxies and alter their color. We study the major interactions in filaments and sheets using SDSS data to understand the influence of large-scale environments on galaxy interactions. We identify the galaxies in filaments and sheets using the local dimension and also find the major pairs residing in these environments. The star formation rate (SFR) and color of the interacting galaxies as a function of pair separation are separately analyzed in filaments and sheets. The analysis is repeated for three volume limited samples covering different magnitude ranges. The major pairs residing in the filaments show a significantly higher SFR and bluer color than those residing in the sheets up to the projected pair separation of ∼50 kpc. We observe a complete reversal of this behavior for both the SFR and color of the galaxy pairs having a projected separation larger than 50 kpc. Some earlier studies report that the galaxy pairs align with the filament axis. Such alignment inside filaments indicates anisotropic accretion that may cause these differences. We do not observe these trends in the brighter galaxy samples. The pairs in filaments and sheets from the brighter galaxy samples trace relatively denser regions in these environments. The absence of these trends in the brighter samples may be explained by the dominant effect of the local density over the effects of the large-scale environment.
An integrated approach to improving the ability of power systems to accept distributed PV
Authors: Lu Yu , Zhang Dachi , Yu Miao , Liu Peng , Wang Jing , Zhou Ziyi 
Published: December 2022

Abstract
At this stage, the main way to develop solar resources is to use the photovoltaic effect as a basis for solar power generation. The article first outlines the problems faced by the power system in accepting distributed photovoltaics, then discusses the “measures to strengthen the power system’s ability to accept distributed photovoltaics”, and proposes measures from the source-load side, the grid side, and the interaction between the two sides. Satisfying the interval number constraint, line transmission capacity constraint, substation capacity constraint, and total investment constraint of the grid-connected line, the optimal access method can give full play to the acceptance capacity of the current grid, and finally, the weak link analysis of the acceptance capacity of the distribution grid is carried out with a regional distribution grid as an example. It is hoped that the discussion in this paper will inspire people in some way and contribute to the effective integration of the power system and distributed PV.
Application of Fourier’s Law in One-Dimensional Steady Heat Conduction Calculation of Cylinder Wall
Authors: Wang Yarong , Wang Peirong 
Published: December 2022

Abstract
When a temperature gradient exists in a body, experience has shown energy transfers from the high-temperature region to the low-temperature region. The energy is transferred by conduction. The fundamental law of heat conduction is called Fourier’s law. The problem is simple if a system is in a steady state (i.e., the temperature does not change with time). The one-dimensional heat conduction in a steady state is the simplest. Through an example, we apply Fourier’s law to analyze the one-dimensional stable heat conduction of the cylindrical wall.

Authors: Gao Na , Zhang Xiaobin 
Published: December 2022

Abstract
To deeply study the specific characteristics of the cross-scale phenomenon of fragmentation and atomization in the cross-jet process, this paper is based on the adaptive grid technology, using the RANS model, RNG k-ε model, LES model turbulence models, and VOF models, DPM model, VTD model multiphase flow models have carried out numerical calculations on the lateral jet process, and compared and analyzed the results to better solve the cross-scale problem and obtain more suitable research methods for the phenomenon of lateral jet breaking and atomization. It is found that: compared to the RANS model and RNG k-ε model, the LES model is more suitable for jet breaking; compared with the VOF model and DPM model, the VTD model is closer to the actual physical phenomenon in the cross jet breaking shape, and the initial surface of the liquid column is broken, the columnar broken and the band-shaped liquid filament is broken by a series of broken and atomized phenomena. And a large number of banded or filamentous liquid lumps can be captured in the continuous liquid film stage and the primary crushing stage of the jet, while discrete misty droplets can also be captured in the secondary crushing area. Based on this, this paper finds that the cross-scale VTD model is combined the phase gradient adaptive grid technology can couple the advantages of the VOF model and the DPM model to better solve the transition problem between the continuous phase and the discrete phase, thereby obtaining more accurate jet atomization characteristics.
Numerical Simulation of Curvature and Confining Pressure Effect on Progressive Failure of Surrounding Rock in Arch Tunnel with Straight Wall
Authors: Han Fang , Liu Cen , Wang Yang , Xi Ling-zhi , Tao Shuai 
Published: December 2022

Abstract
Considering the influence of tensile plastic strain of intact rock on tensile strength and elastic modulus. The influence of arch curvature and height of the straight wall on the progressive failure of surrounding rock under different confining pressures are simulated based on the Mohr-Coulomb constitutive model and the nonlinear CWFS criterion of friction strengthening and cohesion weakening. The results show that when λ
1 = 0.2, the difference between vertical load and horizontal load is large, the buckling failure of rock burst and slab cracking is obvious, and the sectional curvature effect is obvious. When λ
3 = 0.5, the buckling failure of rock burst and slab cracking is very limited, the sectional curvature effect is reduced, and the confining pressure effect of rock burst and slab cracking is obvious. The shear yield localization of the surrounding rock is sensitive to sectional curvature, and the sectional curvature effect of shear failure under different lateral pressure coefficients is obvious. The numerical calculation results are consistent with the failure law of surrounding rock obtained from field and laboratory tests, which can provide a reference for tunnel excavation and support design.

Published: December 2022

Abstract
To improve the efficiency of fire investigation, a horizontal pneumatic separator for separating plastic evidence from fire and explosion scenes is designed in this paper. Taking three kinds of material with different densities as separation objects, MATLAB was used to calculate the horizontal displacement of materials under different separation parameters based on the motion equation. A deviation coefficient was put forward to measure the separation effect. The effects of air inlet velocity and air inlet angle on the deviation coefficient of materials with different particle sizes were studied, and the optimal deviation coefficient was determined according to Taguchi methods.

Published: December 2022

Abstract
In this paper, a new (2+l)-dimensional bidirectional Sawada-Kotera-like (BSK-like) equation is constructed by utilizing the generalized Hirota bilinear differential operators with third order. By using the Hirota bilinear method, some rational types of the solutions, especially lump-type solutions of the BSK-like equation, are obtained with the help of the software Maple. The characteristic and dynamic states of the lump-type solutions and the rational-type solutions to the BSK-like equation are shown by plotting with some special values.

Research on Repeatability Calibration of Friction Coefficient of Transverse Force
Authors: Liu Lu 
Published: December 2022

Abstract
The friction coefficient of lateral force is an important index to evaluate the skid resistance of roads. The repeatable calibration technology of the coefficient depends on the road for a long time. The uncertainty introduced by the road surface in the calibration process is large, and the test process needs to close the road, which affects normal traffic. In this paper, the repeatability calibration technology of the lateral force friction coefficient was studied, and an indoor calibration device of the lateral force friction coefficient was developed. The calibration device was built by comparing the transmission scheme and the main component. The repeatability calibration method of the lateral force friction coefficient was designed, and the calibration test was carried out. The measurement uncertainty of the repeatability deviation coefficient was evaluated as U=1% (k=2).
