Authors: Karki Mohan , Rajpal Girish 
Published: August 2024

Abstract
Objective Treatment of ruptured broad-necked intracranial aneurysms by endovascular therapy is technically burdensome. It is commonly treated with stent- and balloon-assisted coils embolization. The aim of this study was to evaluate clinical and radiological outcomes following double micro-catheter (MC) technique.
Materials and Methods A retrospective study was done on 16 broad-necked (neck diameter ≥ 4 mm and dome-to-neck ratio < 2) ruptured intracranial aneurysms in 16 patients treated with double MC technique at our center between December 2021 and December 2023. Clinical outcome was evaluated by modified Rankin Score, postcoiling radiological outcome was evaluated by Raymond–Roy occlusion grade, and treatment-related complications were assessed.
Results There were 16 patients, 9 females and 7 males; with a mean age of 51.3 years (35–70 years). All the patients underwent dual MC coils embolization for all aneurysms. Raymond–Roy occlusion class I was achieved in 81.3% (13) cases and Raymond–Roy class II was achieved in 18.7% (3) cases immediately after the procedure. There were no serious postprocedure-related complications or recanalization of the aneurysm at the mean follow-up of 4.8 months (range 2–10 months).
Conclusion Our study presents the safety and effectiveness of double MC system for treating ruptured broad-necked intracranial aneurysm. Large numbers of studies with longer follow-up period are required to secure validity of double MC technique.
Framing Amish victimization and security through the lens of criminological theory
Authors: Donnermeyer Joseph F. 
Published: August 2024

AbstractThis article explores the crime experience of the Amish, a rural-located religious subculture that is rarely studied by criminologists. Evidence is derived from narratives of crime experiences reported by scribes to a monthly Amish periodical called The Diary. Every month there are reports about community events from hundreds of Amish settlements, including crime. A routine activities approach helps frame the results. From 168 crime narratives, both burglary/attempted burglary and larceny/attempted larceny are the most frequently described. Suggestions for future research, including an expanded collection of crime narratives from The Diary, plus interviews with both law enforcement and other criminal justice practitioners and Amish crime victims will advance criminological understandings of Amish vulnerability to crime. The article concludes with suggested actions to improve safety and security for Amish communities using environmental criminology theories.
Does larger scale enhance carbon efficiency? Assessing the impact of corporate size on manufacturing carbon emission efficiency
Authors: Wang Qiang , Sun Tingting , Li Rongrong 
Published: August 2024

AbstractThis study investigates the impact of corporate scale on manufacturing corporate carbon efficiency (MCEE) using empirical analyses and diverse modeling techniques. The research begins with rigorous unit root and cointegration tests, confirming the stationary nature of the data and establishing long-term equilibrium relationships among the variables. Subsequently, benchmark regression analyses employing various models, including system GMM, reveal a robust and significantly positive association between corporate scale and MCEE. The findings emphasize that as corporate scale increases, there is a substantial enhancement in MCEE, attributed to expanded resources, technological advancements, and improved management systems. Robustness tests employing alternative approaches consistently reaffirm this positive correlation, further validating the pivotal role of corporate scale in augmenting MCEE. Furthermore, nonlinear analyses demonstrate varying impacts across different quantile levels of MCEE, highlighting the consistent positive correlation between corporate scale and MCEE. Additionally, the panel threshold model underscores the influence of environmental regulations, R&D investments, and trade openness on this relationship. Notably, stricter environmental regulations intensify the impact of corporate scale on MCEE, emphasizing the importance of corporate expansion in minimizing environmental costs and enhancing resource efficiency. These findings underscore the significance of corporate scale in driving corporate carbon efficiency. They advocate for corporations to not only expand their production capacities but also focus on optimizing management strategies and resource allocation, particularly in contexts influenced by environmental regulations, R&D investments, and trade openness. Overall, this research contributes comprehensive insights into understanding the dynamics governing corporate environmental efficiency and emphasizes the critical role of corporate scale in fostering environmental sustainability.

Authors: Kim Dong-Kwon , Lee Jaehyun , Lee Dong Jae , Yun Gunsu S. 
Published: August 2024

The two electron cyclotron emission imaging (ECEI) systems installed at adjacent ports (G and H) on the KSTAR tokamak incorporate large-aperture mm-wave optics, broadband electronics, and high speed digitization (up to 1 MSa/s) for 2D and quasi-3D visualization of MHD-scale fluid dynamics. Recently, the ECEI systems have been proved to be capable of visualization of smaller scale fluctuations albeit with a limited spatiotemporal resolution and even capable of measurement of ion cyclotron harmonic waves by direct high-speed sampling of the ECE IF signals. A four-channel prototype subsystem with a higher sampling rate up to 16 GS/s has been integrated into the G-port ECEI system, enabling the measurement of plasma waves in the GHz range in the form of modulated ECE signals and characterization of high-frequency turbulence during the evolution of pedestal. To achieve higher toroidal resolution in the turbulence measurement, the H-port ECEI system is now being upgraded to have a toroidally dual detector array of 2(toroidal) × 12(vertical) × 8(radial) channel configuration and a high-speed subsystem of 2(toroidal) × 4 channel configuration. The new mm-wave optics has been designed via beam propagation simulation, and the measured performance of the fabricated lens indicates a toroidal resolution of 8–10 cm depending on the focus position and zoom factor, allowing for the measurement of parallel wavenumber up to k‖ ∼ 0.8 cm−1.

Published: August 2024

The first mirror is the front-end optic component that reflects light emitted from the plasma to the diagnostic system in fusion plasmas. Silicon carbide (SiC), known for its relatively high mechanical strength and radiation tolerance, has been selected as the substrate material for the first mirror in the ITER divertor vacuum ultraviolet (VUV) spectrometer. To measure the reflectivity of the ellipse cylindrical SiC mirror to be manufactured, a device for reflectivity measurement in the VUV wavelength range was developed. First, the reflectivity of a sample SiC mirror (15 mm diameter × 10 mm thick) was measured across the ITER-required incidence angles, and the results are reported in this study. A hollow cathode lamp with helium gas was used as the VUV light source in the wavelength range of 23–60 nm, and a dedicated VUV spectrometer to select specific wavelengths was developed. The spectrometer utilized laminar-type replica diffraction gratings (Shimadzu 30-006) and two back-illuminated charge-coupled devices (BI-CCD, Andor DO 940P-BEN) for the grating and detector, respectively. A cropping technique with aperture was employed to precisely localize the VUV light’s reflection onto the SiC mirror surface. The experimentally measured reflectivity values of SiC at the required incidence angles of VUV light were compared with theoretically calculated reflectivity curves. The oxidation layer (SiO2) formed on the SiC surface and the incidence angle of VUV light to the BI-CCD chip (E2V) would be the factors affecting the accuracy of the reflectivity.

A new 14 MeV neutron spectrometer utilizing the magnetic proton recoil (MPR) technique is under development for the SPARC tokamak. This instrument measures neutrons by converting them into protons, whose momenta are subsequently analyzed using a series of magnets before detection by an array of scintillators known as the hodoscope. In this work, we explore various solutions for the hodoscope detectors through laboratory tests with radioactive sources and simulations. We present findings on light collection and pulse shape discrimination based on detector types, as well as optimal solutions for photo-detectors studying the differences between SiPM and PMT. Our results also led to the determination of a better optimized design for the hodoscope detectors, consisting of a 0.7 cm width and a 13 cm length EJ276D scintillation rod.

Published: August 2024

The single-line-of-sight time-resolved x-ray imager (SLOS-TRXI), a fast-gated x-ray imager used for capturing x-ray self-emission in inertial confinement fusion experiments on OMEGA, has been upgraded and characterized. SLOS-TRXI combines an electron-dilation imager and a hybrid complementary metal–oxide–semiconductor (hCMOS) sensor to capture multiple gated frames on a single line of sight with a temporal resolution of ∼40 ps and a spatial resolution of 10 µm. The original hCMOS sensor with four frames was replaced with a newer-generation hCMOS sensor having eight frames. Gate characterizations of both the sensor and the entire SLOS-TRXI diagnostic were performed using ∼10-ps FWHM visible (2ω) and UV (4ω) short-pulse lasers, respectively. A stepped echelon was used to generate a train of five UV laser pulses having an interpulse separation of 30 ± 3 ps. Characterization results of the hCMOS gating (2.28 ± 0.02-ns FWHM on average) and a temporal resolution of the upgraded SLOS-TRXI (34 ± 4-ps FWHM on average) are presented. A temporal magnification for the electron-dilation imager between 40 and 60 was inferred from the characterization results. The spatial resolution of the upgraded SLOS-TRXI remains the same in light of this work.

Published: August 2024

Abstract
The minimum miscibility pressure (MMP) is a crucial parameter in assessing the miscibility of CO2 displacement and evaluating the effectiveness of oil displacement. Traditional methods for calculating MMP are intricate and time-consuming, involving numerous related parameters. Therefore, precise and efficient determination of MMP is highly significant in the development of CO2-driven reservoirs. This study first utilized the Pearson correlation coefficient to analyse the correlation factor mechanism of 36 sets of fine-tube experimental data. Subsequently, the physical information neural network prediction model was employed with reservoir temperature, crude oil composition, and injected gas type as input parameters. The PRI state equation and Glaso correlation equation drove the model, with parameter optimization and training conducted under both physical and data driving. The model demonstrates high prediction accuracy and strong generalization ability. Finally, Validation of the model was performed using fine-tube experimental data from 5 other wells, revealing a relatively small relative deviation between calculated and experimental values, with an average coefficient of determination of 0.95 and an average relative error of 4.42%. The prediction accuracy was improved by about 75% compared to other machine learning algorithms. This model holds potential for application in on-site reservoir development, enhancing the measurement accuracy of the minimum miscible pressure of pure CO2 flooding, greatly shortening the design cycle of reservoir development, expediting the process of reservoir development, and providing technical guidance for improving oil and gas recovery and pure CO2 flooding exploration and development.

Published: August 2024

Abstract
An intelligent visual detection method is proposed to identify early surface damage in operational mine hoist steel wire ropes (MHWRs), addressing challenges arising from complex surface morphology, subtle early-stage damage, and difficulties in identification. The method is based on an improved YOLOv5 (you only look once) network, a visual detection system has been developed, and on-site experiments and applied research are currently underway. Firstly, the operating conditions of the in-service MHWRs were analyzed. In response to their dynamic hoisting characteristics and complex surface morphology, a detection system framework based on high-speed visual perception and deep intelligent algorithms was proposed. Then, the Retinex and convolutional block attention module (CBAM) attention mechanism modules were introduced to solve the problems of uneven illumination and subtle early-stage damage, and a visual recognition network model for detecting surface early-stage subtle damage in MHWRs was constructed on the YOLOv5 base module, referred to as MineWR-net. Subsequently, based on the evolutionary process of surface damage in MHWRs, a dataset for early-stage damage was established, and performance comparative studies were conducted on various object detection algorithms. Finally, integrating practical operating conditions and application requirements, on-site experimental research was carried out for the MHWRs visual detection system. The results indicate that the designed MHWRs visual inspection system can achieve dynamic and clear acquisition of the surface image of serving steel wire rope under high-speed movement. Compared with other target detection algorithms, the average detection accuracy (Map) of MineWR-net is 82.3%, which has superior detection performance. This research can provide technical support for the industrial application deployment of the healthy operation and maintenance of MHWRs.
A new denoising method of ship-radiated noise: Improved variational mode decomposition coupled with fractional order entropy double threshold criterion
Authors: Li Guohui , Zhang Liwen , Yang Hong 
Published: August 2024

Abstract
Ship-radiated noise (SRN) contains abundant ship characteristic information. The detection and analysis of SRN is very important for ship target recognition, positioning and tracking. However, complex ocean noise easily interferes with the propagation of SRN in water. To achieve a preferable denoising effect, a new denoising method for SRN is proposed. First, the SRN is decomposed by an improved variational mode decomposition (DVMD) by a dung beetle optimizer, and the complexity of each intrinsic mode function after decomposition is measured by the fractional order refined composite multiscale fluctuation dispersion entropy (FRCMFDE). Second, the entropy distribution characteristics are analyzed, and different adaptive division methods are used to determine the entropy distribution characteristics of different modes, i.e. it divides all modes into clean modes, mildly noisy modes, moderately noisy modes and highly noisy modes. Then, locally weighted scatterplot smoothing and improved dual-tree complex wavelet transform (IDTCWT) are used to denoise the mildly noisy modes and moderately noisy modes, respectively. Finally, the denoised SRN is obtained by reconstructing the two groups of denoised modes and clean modes. The proposed denoising method is used to denoise Rossler, Chen and Lorenz signals, and the signal-to-noise ratio (SNR) is improved by 13.0785, 11.9390 and 12.3775 dB, respectively. Compared with DVMD-FRCMFDE, DVMD-FRCMFDE-wavelet soft threshold denoising (WSTD) and DVMD-FRCMFDE-IDTCWT, the SNR of the proposed denoising method is increased by 48%, 45.93% and 38.76%, respectively, and the root mean square error is increased by 46.55%, 42.76% and 30.04%, respectively. The proposed denoising method is applied to four types of measured SRN. Based on these findings, the proposed denoising method enhances clarity and smoothness of the phase space attractor, and effectively suppresses marine environmental noise in SRN, which provides solid groundwork for subsequent processing of SRN.
Ligand-assisted reprecipitation synthesis of highly luminescent and stable CsPbBr3@SiO2 nanoparticles with formation kinetics analysis
Authors: Huang Chien-Hao , Chu Sheng-Yuan 
Published: August 2024

Abstract
Cesium lead bromide (CsPbBr3) perovskite nanocrystals are becoming a popular alternative to chalcogenide quantum dots because of their bright green fluorescence and high color purity. However, owing to the poor stability caused by their highly ionic nature and the dynamic binding of long-chain capping ligands, their practical applications are limited. Although (3-aminopropyl)triethoxysilane (APTES) is a frequently used insulating material for wrapping CsPbBr3 nanocrystals, it often causes surface etching. To address this issue, we introduced oleic acid into the anti-solvent toluene to inhibit the etching effect of APTES using a modified room-temperature ligand-assisted reprecipitation process. We utilized in situ time-dependent photoluminescence measurements to study the formation kinetics of CsPbBr3 nanocrystals and determine the optimal ligands ratio. This innovative approach enables precise control over CsPbBr3@SiO2 nanoparticles synthesis, yielding uniformly shaped nanocrystals with a silica shell, a consistent size around 10.17 ± 1.6 nm, and enhanced photoluminescence quantum yields ranging from 90% and 100%. The photoluminescence lifetimes of our CsPbBr3@SiO2 nanoparticles were significantly prolonged owing to a reduction in non-radiative recombination. This boosts their stability in thermal and polar solvent environments, making them superior candidates for use in photonic devices.

Published: August 2024

Abstract

Objective. Arterial pulse wave analysis (PWA) is now established as a powerful tool to investigate the cardiovascular system, and several clinical studies have shown how PWA can provide valuable prognostic information over and beyond traditional cardiovascular risk factors. Typically these techniques are applied to chronic conditions, such as hypertension or aging, to monitor the slow structural changes of the vascular system which lead to important alterations of the arterial PW. However, their application to acute critical illness is not currently widespread, probably because of the high hemodynamic instability and acute dynamic alterations affecting the cardiovascular system of these patients. Approach. In this work we propose a review of the physiological and methodological basis of PWA, describing how it can be used to provide insights into arterial structure and function, cardiovascular biomechanical properties, and to derive information on wave propagation and reflection. Main results. The applicability of these techniques to acute critical illness, especially septic shock, is extensively discussed, highlighting the feasibility of their use in acute critical patients and their role in optimizing therapy administration and hemodynamic monitoring. Significance. The potential for the clinical use of these techniques lies in the ease of computation and availability of arterial blood pressure signals, as invasive arterial lines are commonly used in these patients. We hope that the concepts illustrated in the present review will soon be translated into clinical practice.
Accuracy and scalability of incompressible inductionless MHD codes applied to fusion technologies

Published: August 2024

Abstract
It is well-known that magnetohydrodynamics (MHD) dominates the dynamic of the liquid metal flows inside the breeding blankets (BB) of future nuclear fusion plants by magnetic confinement. MHD is a multiphysics phenomenon involving both electromagnetism and incompressible fluid mechanics. From the computational point of view, the simulation of MHD flows in fusion relevant conditions entails a significant challenge. Indeed, due to the shape of the induced electrical currents inside the bulk of the fluid, high spatial resolutions are needed to capture the large gradients found in boundary layers and 3D effects. Besides, solving the equations accurately typically requires very small time steps for the transient algorithms. Over the past few decades, some parallel MHD codes have been developed with success to simulate complex flows in increasingly realistic geometries. Among them, the MHD tools of commercial CFD platforms have attracted attention due to their relatively soft learning curve. Most of these codes are based on the so called ϕ-formulation which, by applying the divergence free condition of the current density to the Ohms law, reduces the electromagnetic part of the problem to a single Poisson equation. As a downside, the approach segregates the fluid and electromagnetic problem. In practice, this establishes important limits to the mesh element size, to the mesh quality and to the time-step needed to obtain accurate and stable solutions that maintains charge conservation at a discrete level. In this work, these limits are explored for the commercial platform ANSYS-Fluent using a test geometry under different conditions. As an alternative, a new code based on Finite Element Methods (FEM) is introduced as well. This open-source code, called GridapMHD (https://github.com/gridapapps/GridapMHD.jl), aims at solving the full set of MHD equations using a monolithic approach. GridapMHD is still in early stages of development but it has already shown promising results.
