Abstract
We present an approach to investigate the localized surface plasmon resonance and surface-enhanced Raman scattering of gold films deposited on uncured polydimethylsiloxane via thermal evaporation. Differing from solid substrates, the liquid surface of uncured polydimethylsiloxane can serve as an isotropic substrate on which gold atoms nucleate and disperse to form characteristic microstructures in a controlled manner. By adjusting experimental parameters during film deposition, the absorption of resonant plasmon modes can be tuned in the visible spectral range due to the control of particle size and distribution in Au films. Furthermore, Raman measurements are conducted to investigate the enhancement of Raman signals in these films, and the experimental results are verified by simulation analysis. This work exhibits tunability of surface plasmon resonance frequency and enhanced Raman detection capability by depositing metal films on liquid surfaces, thus providing potential applications of these films in flexible biosensors and chemical detection.

Published: October 2023

Abstract
Preferential concentration in turbulent flows laden with inertial particles still presents many open fundamental physics questions. These gaps hinder the reconciliation of different experimental and numerical studies into a coherent quantitative view, which is needed to enable accurate high resolution modeling. We examine the influence of the dimensionality of the measurement technique (1D line, 2D planes or 3D volumes) on the characterization of cluster properties/preferential concentration, and proposes an approach to disentangle the cluster-characterizing results from random contributions that could contaminate the cluster statistical analysis. We studied this effect by projecting 2D and 3D data snapshots containing inertial particle clusters onto a 1D axis. The objective was to simulate 1D sensors (widely used experimentally: hot wire, fiber optics probes, LDV/PDA, etc) with different sensing lengths. These projected records were analysed by means of one-dimensional Voronoï tessellations. For the experimental parameters explored in this study, our results retrieved average clustering properties, when the measuring window is equal or larger than the Kolmogorov length scale (η), and smaller than

10
%

of the integral length scale of the turbulence

L

. These observations are consistent with previous research using 2D and 3D datasets taken under similar experimental conditions. The raw probability density function (PDF) of the Voronoï length in 1D does not provide error-free information on the clusters size or local concentration. This measurement bias is corrected based on the histograms of the number of particles within each cluster. Importantly, the analysis of these histograms explains the well-known clusters size PDFs power law reported in previous numerical and experimental research using 2D and 3D datasets. This power-law behavior, however, spanning less than a decade, is not robust in 1D. To address this, we use conditioned statistics (on the number of particles inside each cluster) to discern between turbulence-driven clustering and random particle concentration fluctuations. This secondary analysis complements standard cluster identification algorithms that rely on Voronoï tessellations.

Abstract
Resistive memory has become an attractive new memory type due to its outstanding performance. Oxide-based resistive random access memory is one type of widely used memory whose resistance can be transformed by applying current or voltage. Memristors are widely used in various kinds of memories and neural morphological calculations. Therefore, it is of vital importance to understand the physical change mechanism of an internal memristor under stimulation to improve electrical properties of the memristor. In our studies, a device model based on Hf oxide was proposed, then completely processes of the forming, reset and set were simulated. Meantime, the generation and recombination of oxygen vacancies were considered in all the processes, making the simulation more practical. In addition, a spike electrode structure was applied, a gathering electric field can be generated in the oxide layer so that the improved device has a faster forming voltage, lower forming current and lower instantaneous power consumption in the ON state. Finally, the effects of spike electrode length on the forming process were studied, the research results reveal that a longer probe electrode can engage a lower forming voltage and accelerate the formation of conductive filaments.

Authors: Gao Peng 
Published: October 2023

Abstract
In this paper, we consider the multiscale random Korteweg–de Vries-Burgers (KdVB) equation, namely, the KdVB equation perturbated by a fast time oscillating external force and a random oscillating noise, the random oscillating noise is made up of a family of strong mixing stationary processes with singular small parameters. A Stratonovich–Khasminskii type averaging principle for multiscale random KdVB equation is established, in physics, this averaging principle can describe the asymptotic behavior for the propagation of small-amplitude long waves in nonlinear dispersive and dissipative media with singular structure and the soliton propagation in the random weakly viscous media or in the random field.

Published: October 2023

Abstract
The automated marker-free longitudinal Infrared (IR) breast image registration overcomes several challenges like no anatomic fiducial markers on the body surface, blurry boundaries, heat pattern variation by environmental and physiological factors, nonrigid deformation, etc, has the ability of quantitative pixel-wise analysis with the heat energy and patterns change in a time course study. To achieve the goal, scale-invariant feature transform, Harris corner, and Hessian matrix were employed to generate the feature points as anatomic fiducial markers, and hybrid genetic algorithm and particle swarm optimization minimizing the matching errors was used to find the appropriate corresponding pairs between the 1st IR image and the nth IR image. Moreover, the mechanism of the IR spectrogram hardware system has a high level of reproducibility. The performance of the proposed longitudinal image registration system was evaluated by the simulated experiments and the clinical trial. In the simulated experiments, the mean difference of our system is 1.64 mm, which increases 57.58% accuracy than manual determination and makes a 17.4% improvement than the previous study. In the clinical trial, 80 patients were captured several times of IR breast images during chemotherapy. Most of them were well aligned in the spatiotemporal domain. In the few cases with evident heat pattern dissipation and spatial deviation, it still provided a reliable comparison of vascular variation. Therefore, the proposed system is accurate and robust, which could be considered as a reliable tool for longitudinal approaches to breast cancer diagnosis.

Abstract
Superconducting joint technologies connecting high-T
c superconducting (HTS) tapes, such as REBCO-coated conductors and Bi2223 silver-sheathed tapes, have been developed for the fabrication of superconducting magnets generating 30.5 T with persistent current operation at 4.2 K under the JST-Mirai Program since 2017. These are indirect joints using a superconducting intermediate layer to join highly crystallized HTS layers of tapes. Thus far, high I
c values of above 100 A at 77 K in the self-field have been achieved by both joints. These performances are sufficient for installation to the 30.5 T magnet, while efforts to further improve the reproducibility of high I
c for joints connecting long-length HTS tapes have been continuously made. The current status of HTS joint technologies is summarized in this paper partly from the view point of material science.
Dynamical model and numerical study of cavitation bubble in ultrasonic assisted electrochemical polishing solution of selective laser melting NiTi alloy
Authors: Che Jianwei , Shi Guangfeng , Zhou Tianwen 
Published: October 2023

Abstract
In the process of ultrasound assisted electrochemical polishing of selective laser melting (SLM) NiTi alloy, a large number of cavitation bubbles will be generated in the anode and cathode, and these cavitation bubbles will expand and compress rapidly until finally collapse. At the moment of collapse, high temperature and high pressure will occur, and at the same time, pressure shock wave and micro-jet will be produced, which will have a certain impact on material removal during polishing. In order to explore the mechanism of ultrasonic assisted electrochemical polishing, in this paper, the dynamics of cavitation bubbles with free interface and rigid interface are analyzed by ultrasonic assisted electrochemical polishing. The dynamics models of single cavitation bubble and two cavitation bubbles are established. The fourth order Runge–Kutta method was used to solve the model numerically, and the influence of electric field intensity, initial bubble radius, sound pressure amplitude and ultrasonic frequency on the dynamics of cavitation bubble was analyzed. The results show that in the range of f = 1–10 KHz, the initial radius of bubble is 0.01–0.05 micron, the sound pressure amplitude is 103 Pa, and the electric field intensity is 104 V m−1, the cavitation movement gradually becomes regular, and it goes through a complete process of expansion, contraction and then collapse, which is beneficial to the cavitation effect. This provides a theoretical basis for further research on the mechanism of ultrasonic assisted electrochemical polishing of SLM-NiTi alloy, which is of great significance for broadening the processing of additive manufacturing parts with low cost, high efficiency, and consistent quality.

Published: October 2023

Abstract
Optical detection, measurement, and treatment methods are widely used in the medical industry nowadays. The evolution of radiated beams, received power and beam size play vital roles while developing devices. The propagation properties of hollow higher-order cosh-Gaussian beam (HHOCGB) while propagating in human upper dermis tissue are derived analytically and analyzed numerically. The impact of the hollowness parameter, beam order, operating wavelength, and Gaussian beam waists on the beam’s intensity profile is examined. Received power and beam size variations are analyzed considering operating wavelength and Gaussian waist width. According to the results, as the beam propagates, its profile rapidly evolves into a shape with a circular Gaussian peak in the center and petals at the corner. Dark hollow regions are observed among the petals. Furthermore, the received power by HHOCGBs with a higher Gaussian waist width is more than those received by beams with a lower Gaussian waist width. However, at far field, operating at a lower wavelength prevents the increase of the beam spread. Thus, the obtained results will be significant in the bio-optical disease detection and treatment technology development.
Starting inflation from inhomogeneous initial conditions with momentum
Authors: Corman Maxence , East William E. 
Published: October 2023

Abstract
We investigate the circumstances under which cosmic inflation can arise from very inhomogeneous initial conditions using numerical relativity simulations.
Previous studies have not considered cases with non-zero momentum density
due to technical challenges with solving the coupled Einstein constraint
equations. Here we address these, introducing and comparing several
different ways of constructing cosmological initial conditions with
inhomogeneous scalar field and time derivative profiles. We evolve such
initial conditions with large inhomogeneities in both single- and two-field
inflationary models. We study cases where the initial gradient and
kinetic energy are much larger than the inflationary energy scale, and black
holes can form, as well as cases where the initial scalar potential energy
is comparable, as in scenarios where inflation occurs at nearly Planckian
densities, finding large-field inflation to be generally robust. We
consider examples of initial conditions where a large scalar field velocity
towards non-inflationary values would prevent inflation from occurring in
the homogeneous case, finding that the addition of large gradients in the
scalar field can actually dilute this effect, with the increased expansion
and non-vanishing restoring force leading to inflation.

Abstract
Robots have existed for a long time with their primary purpose to make the daily lives of humans easier. Today there are a variety of robots available each for a different purpose; some are used in the industry whereas some are used for home applications. Lately the trend of surveillance-based robots is going on, the best example of this is a drone. Drones have a camera attached to them and the operator is given the controls to guide the drone and get the appropriate footage. The main disadvantage of a drone is its stability and that it needs ample space to travel. These drawbacks are eliminated by a camera-mounted robot on a set of three wheels. These robots can be guided from the narrowest of the passage and stability is something the operator need not worry about.

Abstract
Sm3+ ion doped TeO2: ZnF2: BaO glasses are prepared in different atmospheres by melt quenching technique. The glasses structure was analyzed using a Rigaku SmartLab SE X-ray diffractometer (XRD). Absorption spectra (Shimadzu, 3600) in the wavelength between 400 to 1800 nm were recorded using a UV-VIS-NIR spectrophotometer. They found a total of seven peaks, which corresponded with the energy transitions of Sm3+ ion from the ground level 6H5/2 → 6F11/2, 6F9/2, 6F7/2, 6F5/2, 6F3/2, 6H15/2, and 6F1/2 at 944, 1083, 1238, 1383, 1485 and 1543 nm respectively. A spectrofluorophotometer (Cary-Eclipse) was used to detect the photoluminescence, and the excitation spectra were obtained from measurements in wavelengths of 300 to 550 nm using the emission spectrum at 597 nm. from 6H5/2 (ground state) → 4D7/2 (345), 4D3/2 (362), 6P7/2 (375), 6P3/2 (403), 6P5/2 (417) 4G9/2 (438), 4I13/2 (462) 4I11/2 (474), 4G7/2 (501) and 4F3/2 (526) the excited states. Using a 405 nm exciting wavelength, the emission spectra were captured in the 500–750 nm. The lifetime of the sample between the sample prepared in the air atmosphere and the CO2 atmosphere at the excitation wavelength of 405 nm was 0.679 and 0.662 ms, respectively.

Published: October 2023

Abstract
The Sr(2-x)ZnMoO6 phosphors doped with Eu2O3 were produced through the sintering process in the electrical furnace at a temperature of 1100 °C for 6 hours in an air atmosphere. The characteristics of the synthesized phosphors, including their photoluminescence properties and lifetime profile analysis, were investigated, along with their structure using X-ray diffraction analysis (XRD) and FTIR analysis. The crystalline structure of the Sr2ZnMoO6 phosphor was confirmed by a Rigaku SmartLab SE X-ray diffractometer (XRD). The phosphors doped with Eu3+ exhibited excitation bands at various wavelengths, including 362, 380, 394, 415, 465, 525, and 531 nm, and emitted light at 613 nm. The 465 nm was used for excitation, and the emission spectra displayed peaks at 590, 613, 652, and 699 nm, as measured by a Cary-Eclipse spectrofluorophotometer. The highest peak was observed at 613 nm, corresponding to 5D0 →7F2 (reddish-orange) transitions of the Eu3+ ion. The fluorescence decay time system (HORIBA Scientific) measured the decay time of the Eu3+ ion from the transition of 5D0 to 7F2 level. The decay time of phosphors was decreased with increasing the concentration of Eu2O3, which had a decay time of 0.453 to 0.340 ms when monitored at λex = 465 nm. The results obtained in photoluminescence properties. The results suggest that obtained photoluminescence properties of Eu2O3 doped Sr2ZnMoO6 phosphors have potential applications in optoelectronics.

This study investigates the mechanical properties of epoxy based composite material reinforced with natural filler of animal bone powder. The polymer composites were prepared using compression molding process. The plates of 6 mm thickness were prepared with varying amount of reinforcement from 0%, 5%, 10%, 15% and 20% by weight at varying compression loads at constant cure time. The mechanical properties such as tensile, flexural and impact strength, water absorption of composites were evaluated as per ASTM standards. The microstructural evaluations of samples were done using scanning electron microscope. It was found that the mechanical properties of epoxy composite materials reinforced with animal bone powder were significantly improved. The polymer composite of 15 wt.% bone powder reinforcement exhibited higher strength but possesses lower ductility. The scanning electron microscope analysis showed that particles were distributed uniformly in the matrix material.

Published: October 2023

Abstract
Welding technology has played a vital role in the manufacture of complicated structures in automobile, petrochemical, aerospace, power plant, and ship industries. Tungsten Inert Gas welding process is superior technique and produces high quality weld economically. Aluminum alloy 4043 is currently preferred material in automobile, kitchen utensils and aviation industry sector due to its lightweight properties. The effective TIG welding process for AA4043 material is not studied yet with regard to micro-hardness, impact strength properties in correlation with the microstructure. Hence, consequence of welding parameters, namely welding current, voltage, and weld speed on micro-hardness, impact strength is studied based on Taguchi method. As per the developed experimental matrix, the TIG welded samples of AA4043 plates are produced using the tungsten electrode and filler wire of AA4043 in pure argon as shielding gas. Micro-hardness, impact tests are performed on welded samples and microstructures of different zones of weld are evaluated. Weld zone has highest micro hardness compared to heat affected zone (HAZ) and base metal due to presence of small grain structure. As current increases, large amount of solute enrichment in weld zone and HAZ, whereas severe grain structure change is predominantly observed in transition zone. The optimal parameters are obtained as welding current of 180 A, the voltage of 45 V and welding speed of 3.5 mm/sec for maximum micro-hardness of weld zone and impact strength of weld joint.

Abstract
All-terrain vehicle (ATVs) is a mature and well-cultivated product with prominent significance all over the world. As these products are made to be driven by hoonigans, safety is the main matter of concern. This research paper conducts a crash test analysis on an All- Terrain Vehicle (ATV) chassis to evaluate its structural integrity and occupant safety during collisions. Using advanced computational modeling and finite element analysis, various crash scenarios like Frontal and Side impact crash (considering the driver’s weight) with a wall, Modal analysis, and Static structural analysis are simulated. The 3D finite element model considers material properties and geometry, analyzing acceleration, displacement, deformation, and stress distribution within the chassis. The study assesses the chassis’s ability to absorb impact energy and protect occupants, examining the effectiveness of safety features like roll cages and seat restraints
