Psychometric properties of survey translations
Authors: Mellinger Christopher D. , Hanson Thomas A. 
Published: October 2024

Abstract
Psychometrics involves the indirect measurement of latent constructs, including aspects of cognition and emotion,
and Likert-type scales are a common tool to operationalize and quantify these constructs. One threat to the psychometric
properties of such scales is the administration of surveys across multiple languages, which presupposes the translation of the
survey instruments. While multiple recommendations exist on best practices in translation, implementation does not always satisfy
such guidelines. This article employs Monte Carlo simulation to explore the potential effects of translation on survey measurement
and psychometric properties. Three possible challenges are explored, namely ambiguity, shift in valence, and issues with negation.
These translation effects are statistically modeled as increased variance, change in skewness, and reverse coding, respectively.
Additionally, the simulation examines the value of multi-item scales over single-item measurement. Overall, the results illustrate
how survey translation can impact exploratory factor analysis and reliability of measurement.
Multimodal exploration of the thank God expressive
construction and its implications for translation
Authors: Martínez Fernando Casanova 
Published: October 2024

Abstract
Multimodal research in communication and translation studies is
increasingly recognized, yet it remains incompletely explored. Leveraging
computational linguistics with both Praat for acoustic analysis and the OpenPose
and Rapid Annotator tools for visual analysis, this study delves into the
intricate dynamics of the expressive construction thank God,
providing a comprehensive examination of both visual and acoustic dimensions.
Our objective is to uncover nuanced patterns of multimodal communication
embedded within this expression and their implications for Translation and
Interpreting. Through an analysis of linguistic features and co-speech gestures
present in thank God, we aim to deepen our comprehension of how
meaning crisscrosses modalities. Our findings underscore the necessity of a
multimodal approach in language studies, emphasizing the requisite to preserve
emotional and contextual nuances. The analysis unveils the phonological
relevance of the duration of the construction’s second vowel, a key factor for
translation. Additionally, data reveals a correlation between the emotion of
relief and gestures executed with both hands closer to the chest. Overall, these
findings contribute to advancing both multimodal communication research and
translation studies, shedding light on the role of multimodal analysis in
understanding language and translation dynamics, particularly in the context of
constructions like thank God.

Authors: Hou 侯 Wen-Tao 文涛 , Zang 臧 Jiadong 佳栋 
Published: October 2024

Abstract
Nonlinear Hall effect (NLHE) has been detected in various of condensed matter systems. Unlike linear Hall effect, NLHE may exist in physical systems with broken inversion symmetry in crystals. On the other hand, real space spin texture may also break inversion symmetry and result in NLHE. We employ the Feynman diagrammatic technique to calculate non-linear Hall conductivity (NLHC) in three-dimensional magnetic systems. The results connect NLHE with the physical quantity of emergent electrodynamics which originates from the magnetic texture. The leading order contribution of NLHC, χabb
, is proportional to the emergent toroidal moment

On the nonequilibrium dynamics of gravitational algebras
Authors: Cirafici Michele 
Published: October 2024

AbstractWe explore nonequilibrium features of certain operator algebras which appear in quantum gravity. The algebra of observables in a black hole background is a TypeII∞von Neumann algebra. We discuss how this algebra can be coupled to the algebra of observable of an infinite reservoir within the canonical ensemble, aiming to induce nonequilibrium dynamics. The resulting dynamics can lead the system towards a nonequilibrium steady state which can be characterized through modular theory. Within this framework we address the definition of entropy production and its relationship to relative entropy, alongside exploring other applications.
Electromagnetic Debye mass within Gribov–Zwanziger action
Authors: Bandyopadhyay Aritra 
Published: October 2024

Abstract
In the present study we have investigated the electromagnetic Debye mass by computing the static limit of the temporal component of the one-loop photon polarization tensor involving effective quarks in the loop. These effective quarks have been considered within the Gribov–Zwanziger action, thereby incorporating the necessary non-perturbative effects. As an academic exercise, we have also shown one of the applications of this Gribov modified Debye mass by using it to evaluate the real and imaginary parts of the heavy quark potential in a Quantum Electrodynamics (QED) system. This computation of the electromagnetic Debye mass and the corresponding estimations of the heavy quark potential can be seen as stepping stones in the direction of further practical Quantum Chromodynamics (QCD) calculations in the non perturbative domain.
Heat transfer origin of adhesion behaviors between liquid-aluminum and solid aluminum/silicon interfaces
Authors: Dong Yun , Hui Weibin , Ding Yusong , Lian Fangming , Yan Lianjia 
Published: October 2024

Abstract
Liquid-aluminum tends to adhere to some surfaces rather than others, and the underlying mechanism of the differences in adhesion of liquid-aluminum on different surfaces is still unclear. This manuscript takes liquid-aluminum/aluminum and liquid-aluminum/silicon interfaces as research objects, revealing that solid aluminum surface is aluminophilic but the solid silicon surface is aluminophobic, mainly due to differences in interfacial thermal conductance (ITC) between two interfaces. We also investigate effect of surface temperature on adhesion characteristics of liquid-aluminum on aluminum/silicon surfaces, and decode the reasons from lattice integrity and phonon spectra. It is shown that vibrational state with intact lattice excites fewer low frequency phonons with increasing surface temperature, resulting in a decrease in ITC and thus adhesion force. In diffusion state where lattice is fractured resulting from high temperature, interfacial adhesion is increased due to surface defects.

Published: October 2024

Abstract
Accurate and point-of-care cholesterol detection is of paramount significance for the prevention of cardiovascular diseases. The colorimetric assay based on peroxidase is a commonly used approach for cholesterol detection, without requiring any complicated biomolecular labeling or sophisticated instrumentation. Copper nanoclusters (CuNCs), exhibiting luminescent properties and peroxidase activity, have garnered significant attention in biomedical application recently. Herein, the glutathione-stabilized copper nanoclusters (GSH-CuNCs) were prepared with an easy one-pot method, employing glutathione as both a reducing agent and stabilizer. An optimization of the GSH-CuNCs preparation was carried out to obtain the highest peroxidase-like activity. UV-Vis absorption was measured to explore the steady-state kinetics of the GSH-CuNCs-catalyzed oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) by H2O2. A colorimetric method for cholesterol detection was developed by combining the catalytic reaction of CuNCs and the enzymatic oxidation of cholesterol with cholesterol oxidase (ChOx). Under the optimized conditions, the UV-Vis absorbance of oxidized TMB (oxTMB) is proportional to the concentration of cholesterol within the range of 6.2–187.5 μM, and the limit of detection (LOD) is determined to be 3.0 μM. More importantly, cholesterol levels can be directly distinguished with the naked eye. Furthermore, the practicality of the method for detecting cholesterol in human serum has been verified with promising results. As expected, this simple, cost-effective, and easy-to-operate colorimetric method for cholesterol detection has potential applications in clinical diagnosis and provides valuable insights into the colorimetric sensing based on CuNCs.

Authors: Zhang Xuebing , Li Shunjie , Yuan Yuan , An Qi 
Published: October 2024

Abstract
The management of predator-prey systems, particularly those with discontinuous harvesting, plays a crucial role in maintaining ecological balance and ensuring the sustainable use of renewable resources. Despite the importance of this topic, the dynamics of diffusive predator-prey models with discontinuous harvesting have not been thoroughly explored in existing literature. This study addresses this gap by investigating a diffusive predator–prey model incorporating a discontinuous harvesting function. We establish the existence and boundedness of solutions, analyse the conditions under which a positive steady state is achieved, and explore the model’s stability, including global asymptotic stability and convergence in finite time. Additionally, we examine the effects of Turing instability, Hopf bifurcation, and steady-state bifurcation within the model. Numerical simulations are provided to illustrate the impact of discontinuous harvesting on the system’s dynamics, highlighting the practical applications of the theoretical results in fields such as pest control. The findings of this study offer valuable insights for the design of effective population management strategies in ecological and agricultural contexts.
Effect of thermal shock on energy density of biaxially oriented polypropylene films for pulsed power capacitors
Authors: Chen Ke , Du B X , Liu Haoliang , Xiao Meng 
Published: October 2024

Abstract
In this paper, thermal shock experiments are performed on the biaxially oriented polypropylene (BOPP) films, and the changes in dielectric and energy storage properties before and after the experiments are explored. The experimental results show that the films have reduced comprehensive performance with the thermal shock time and frequency increasing. After the thermal shock, both the permittivity and the dielectric loss increase slightly. And, the direct current (DC) conductivity has risen by 73.6%–714.2%. The lowest DC breakdown strength of film is 604.4 kV mm−1, showing a 13.5% reduction compared to that of pristine film. In addition, energy storage performance has also deteriorated. The maximum discharge energy density decreased from 4.62 J cm−3 of pristine film to 3.26 J cm−3 of treated film. There is a decrease in charge and discharge efficiency under the same electric field. The metallization layer of the film receives less influence; the capacitance is reduced by only 0.37%. The causes and mechanisms of performance changes are analyzed and discussed. The disruption of molecular chains during thermal shock is the most important factor leading to the degradation of films. This paper provides a powerful perspective and reference for studying the performance degradation and failure of polymer dielectrics under extreme operating conditions.
Investigating zero-point vibrations of solid hydrogen via statistical moment method
Authors: Tam Nguyen Trong , Hoang Hai , Lam Le Thu , Hieu Ho Khac 
Published: October 2024

Abstract
Zero-point vibrations of solid hydrogen are investigated by analyzing the molecular mean-squared displacement (MSD) and mean-squared relative displacement functions within the statistical moment method approach in statistical mechanics. Numerical computations of these thermodynamic properties were conducted for solid hydrogen from 0 K to its phase transition temperature using the Wigner-Kirkwood mean-field potential derived from the Buckingham exp-6 potential. We have shown that the quantum-mechanical zero-point vibrations play an important role at low temperature. And these thermodynamic quantities increase with temperature, suggesting that both thermal and quantum effects play a significant role near the liquid-solid phase transition. The favorable consistency between our findings and the recent experimental inelastic neutron scattering measurements of MSD attests to the potential of SMM as a novel approach for determining the atomic vibrations of solid hydrogen. This approach allows us to study these effects including the anharmonicity of lattice vibrations.

Abstract
Palomar Gattini-IR (PGIR) is a wide-field, synoptic infrared time domain survey covering ≈15,000 sq. deg. of the accessible sky at ≈1–3 night cadence to a depth of J ≈ 13.0 and ≈14.9 Vega mag in and outside the Galactic plane, respectively. Here, we present the first data release of J-band light curves of Two Micron All Sky Survey (2MASS) sources within the survey footprint covering approximately the first four years of operations. We describe the construction of the source catalog based on 2MASS point sources, followed by exposure filtering criteria and forced PSF photometry. The catalog contains light curves of ≈286 million unique sources with 2MASS magnitudes of J < 15.5 mag, with a total of ≈50 billion photometric measurements and ≈20 billion individual source detections at signal-to-noise-ratio > 3. We demonstrate the photometric fidelity of the catalog by (i) quantifying the magnitude-dependent accuracy and uncertainty of the photometry with respect to 2MASS and (ii) comparing against forced PGIR aperture photometry for known variable sources. We present simple filtering criteria for selecting reliable photometric measurements as well as example Python notebooks for users. This catalog is one of the largest compilation of nightly cadence, synoptic infrared light curves to date, comparable to those in the largest optical surveys, providing a stepping stone to upcoming infrared surveys in the coming decade.

Authors: Tan Jie , Liu Yuhong , Li Weiming , Wu Daqi , Xue Yuan 
Published: October 2024

Abstract
By analyzing the mechanic’s characteristics of the hydraulic cylinder of the moving arm of the lifting mechanism under several extreme working conditions, the mathematical model of optimizing the hinged position of the lifting mechanism is established with the minimum and maximum load of the hydraulic cylinder of the moving arm as the optimization objective. The problem of multi-objective optimization is dealt with by the method of extremely large and extremely small and solved by the optimization algorithm. Through optimization, the maximum force of the hydraulic cylinders can be markedly reduced, the force characteristics of the lifting mechanism can be improved, and the ultimate load at the hinge point of each hydraulic cylinder can be reduced. The optimization method provides an important basis for the parameter design and improvement of the lifting mechanism and similar products.

Published: October 2024

Abstract
Aiming at the harsh working conditions of aviation bevel gears and the cumbersome design process of traditional tooth blank parameters and other issues, this paper firstly compared the differences between the standards results of the International Organization Standard (ISO) and American Gear Manufacture Association (AGMA) and finds that the calculation of the ISO standard was more instructive. The calculation resulted in the larger module, and the more teeth had a higher load-carrying capacity, which was more suitable for the design of bevel gears for aviation. Then, the ISO standard was used as the strength constraint to propose a multi-parameter optimization technique for bevel gear blanks. Based on the genetic algorithm, with fatigue strength and working condition requirements as double constraints, the design parameters of gear blanks, such as the number of teeth, module, and tooth width, were quickly screened out, which simplified the traditional design process of tooth blank parameters. The final optimization results effectively improved the designed gear’s strength and reduced the gear pair’s volume.

Authors: Huang Dong , Yin Shugui , Mao Luyao , Chen Qiyu , Mo Ting 
Published: October 2024

Abstract
CFD software conducted a hydrothermal simulation study of a triple quadrupole mass spectrometer. The results show that the auxiliary intake fan has a poor effect on cooling the PCB circuit board inside the mass spectrometer, but instead generates a vortex here, affecting the stability of the instrument. Besides, the reinforcing ribs on the bottom plate of the mass spectrometer and the orifice plate in the PCB slot prevent the flow of cooling air, resulting in high flow resistance and low cooling air volume. Therefore, structural optimization was carried out on the bottom plate and orifice plate of the mass spectrometer. The results show that after optimization, the air volume of the main intake fan increased by 6.2%, the air volume entering the PCB slot increased by 29.9%, and its proportion to the air volume of the main intake fan increased by 22.2%. The average temperature of the RF amplification board decreased by 17.3%, resulting in a better cooling effect. Meanwhile, simulation and comparison of the two installation positions of the dustproof cotton showed that installing the dustproof cotton around the bottom plate had a better effect.
Numerical simulation of thermal deformation of oil distribution sleeve based on heat transfer theory
Authors: Lei Fengli 
Published: October 2024

Abstract
In this paper, a study of numerical simulation was conducted based on heat transfer and finite element theory, to analyze the sealing gap change between the oil distribution sleeve (ODS) and the shaft by the effect of temperature. The results showed that the temperature is the dominant reason for the failure of the ODS seal. The thermal deformation of the ODS is radiative expansion and the sealing gap is linearly positively related to the temperature. The wall thickness did not affect the distribution of thermal deformation of the ODS. The sealing gap increases with the increase of the thickness of the inner cylinder but decreases with the increase of the thickness of the outer cylinder. Therefore, keeping a small thickness ratio is conducive to enhancing the sealing performance of the ODS.

Published: October 2024

Abstract
High-speed railway bearings are one of the core transmission components of high-speed railway multiple units, and their degraded performance can directly affect the safety performance of vehicles. How to identify faults in high-speed rail bearings and represent them in data has always been an industry challenge. To this end, multiple frequency domain fault probability fusion models have been proposed for research. The first choice for this model is to provide an analysis method for converting the frequency domain spectrum to fault probability. Subsequently, five frequency domain spectrum analysis methods that are easy to detect bearing faults were selected, and all of them were converted into fault probability. Finally, based on D-S evidence theory, fusion was carried out to obtain multiple frequency domain fault probability fusion models, achieving efficient identification and data representation of high-speed railway bearing faults. Finally, the effectiveness of the model was verified through fault simulation experiments.
Effect of hydraulic oil temperature on the flow output quality of external gear pump
Authors: Li Mingxue , Wu Tao , Wen Run , Chen Wanlong 
Published: October 2024

Abstract
To investigate the impact of hydraulic oil temperature on the performance of an external gear pump, we developed a numerical model to simulate the internal flow field of the pump. Utilizing Computational Fluid Dynamics (CFD) techniques and the full cavitation model, we conducted an analysis on how varying hydraulic oil temperatures affect the pump’s flow quality. Through dynamic numerical simulations, we examined the relationship between hydraulic oil temperature and the flow quality of the gear pump. The findings indicated that the gear pump exhibits optimal flow performance when the hydraulic oil temperature is maintained within a suitable range. Should the temperature deviate from this optimal range, the cavitation within the pump’s flow field intensifies, leading to a decline in the overall flow quality of the gear pump, which worsens with the extent of the temperature deviation.
Simulation and experimental study of heat pump air-side heat transfer
Authors: Bie Yufeng , Zheng Zhu , Yan Zhen , Chen Yunfei 
Published: October 2024

Abstract
A simulation model is developed for the air side of a heat pump dryer which defines the smallest heat exchange unit between fins and air, focusing on the heat exchange between them. A self-constructed test bench was designed to control the temperature and humidity inlet of the heat pump and minimize the impact of environmental factors. The study examined the impact of diverse inlet conditions on heat pump heat transfer performance via a test bench. The experimental results were compared to the simulation outcomes to verify the precision of the model, which recorded a 3.31% outlet temperature deviation. Furthermore, the analysis discovered that the link between the outlet temperature and the inlet air volume of the heat pump demonstrates distinct stage features. When the airflow is below 170 m3/h or above 230 m3/h, the temperature of the heat pump outlet remains almost constant. However, when the airflow falls between 170 m3/h and 230 m3/h, the heat pump outlet temperature becomes dependent on the heat pump’s operational power. The simulation of the unit model under constant temperature boundary conditions and constant heat flow boundary conditions models the variation of outlet temperature and airflow. This model facilitates the thermal design of the heat pump system, particularly for the examination of heat transfer properties under varying inlet conditions. Furthermore, it ensures the validation of the effectiveness of numerical simulation methods in evaluating and enhancing air-side heat transfer in heat pumps for different engineering applications.
