Published: August 2024

AbstractRecent advancements have significantly enhanced the capabilities for in-space servicing, assembly, and manufacturing (ISAM), to develop infrastructure in orbit and on the surface of celestial bodies. This progress is a departure from the traditional sustainability paradigm focused solely on Earth, highlighting the urgent need to define and operationalize the concept of “space sustainability” along with the development of an evaluation framework. The expansion of human activity into space, particularly in low-earth orbit, cis-lunar space, and beyond, underscores the critical importance of considering sustainability implications. Leveraging space resources offers economic growth and sustainable development opportunities, while reducing pressure on Earth’s ecosystems. This paradigm shift requires responsible and ethical utilization of space resources. A space sustainability assessment framework is essential for guiding ISAM capabilities, operations, missions, standards, and policies. This paper introduces an initial framework encompassing (1) pollution, (2) resource depletion, (3) landscape alteration, and (4) space environmental justice, with potential metrics (resources use and emissions, midpoint, and endpoint indicators) to measure impacts in the four domains.

Abstract
Background Percutaneous liver biopsy (PC-LB) has long been the
usual method for acquisition of liver tissue. Recently, endoscopic ultrasound-guided liver
biopsy (EUS-LB) has gained popularity as an alternative modality. We aimed to compare the
efficacy and safety of EUS-LB versus PC-LB.
Methods We systematically searched PubMed, Embase, and the
Cochrane Library databases for randomized controlled trials (RCTs) comparing EUS-LB with PC-LB
published until October 20, 2023. The primary outcome was diagnostic adequacy. Secondary
outcomes were: the number of complete portal tracts (CPTs), longest sample length (LSL), total
sample length (TSL), post-procedure pain scores, and adverse events (AEs), including overall
AEs and AEs excluding minor post-procedure symptoms. We compared binary outcomes using risk
ratios (RRs) and continuous outcomes using the mean difference (MD) or standardized mean
difference (SMD), with 95%CIs.
Results Four RCTs (258 patients) were included. The EUS-LB group
presented lower post-procedure pain scores (SMD −0.58, 95%CI −0.95 to −0.22) than the PC-LB
group. Both groups performed similarly in terms of diagnostic adequacy (RR 1.0, 95%CI 0.96 to
1.04), number of CPTs (MD 2.57, 95%CI −4.09 to 9.22), LSL (MD −2.91 mm, 95%CI −5.86 to 0.03),
TSL (MD 4.16 mm, 95%CI −10.12 to 18.45), overall AEs (RR 0.54, 95%CI 0.20 to 1.46), and AEs
excluding minor post-procedure symptoms (RR 1.65, 95%CI 0.21 to 13.02).
Conclusions This meta-analysis suggests that EUS-LB is as safe
and effective as PC-LB and is associated with lower post-procedure pain scores.Registration on PROSPERO: CRD42023469469.
Exploring the effect of thin film thicknesses on linear and nonlinear optical properties of MoO3 thin film
Authors: Alattar Ammar S. , Nadafan Marzieh , Khashehchi Morteza 
Published: August 2024

The structural, morphological, linear, and nonlinear optical properties of MoO3 thin films deposited by thermal deposition were measured. The effect of various thicknesses of films was studied. The structural and morphological parameters of films, determined by x-ray diffraction, field emission scanning electron microscopy, and AFM images, are compared to the linear and nonlinear optical characteristics of these media. The bandgap of the prepared thin films was obtained from the diffuse reflectance spectroscopy spectra. The electron’s effective mass (me*/m0), linear refractive index (n0), and optical static and high frequency dielectric constant (ɛ0, ɛ∞) values were calculated by using the bandgap energy values. Increasing the thicknesses of thin films decreased the bandgap, increased the root mean square, and increased the size of nanoparticles and the nonlinear response of thin films. The high magnitude of n2 and β was because of MoO3 (300 nm-thickness), which were of the order of 10−5 cm2/W and 10−1 cm/W, respectively. The fluctuations in nonlinear responses observed at different thicknesses are attributed to d–d transitions and intraband scattering of equilibrium electrons influenced by laser radiation, as indicated by the nonlinearity data. The considerably elevated refractive nonlinearity values in the analyzed film materials suggest their potential for practical application in optoelectronic devices.
Equivocation in media communication
Authors: Alroumi Abdulrahman 
Published: August 2024

Abstract
This paper examines equivocation in Arabic and global interviews using interviews with Saudi politician Adel Al-Jubeir as a case study. The study has three main objectives: to assess the applicability of existing frameworks for coding responses in Arabic interviews, to explore the potential discrepancy in question design between Arabic and global interviews and its potential impact on equivocation, and to identify the most frequently recurring responses in these interviews. Rasiah’s (2010) framework is employed to analyse equivocation and coding responses. The dataset includes 2 hours and 45 minutes of Arabic interviews and an equal duration of global interviews. The findings indicate the effectiveness of the proposed frameworks in coding responses in Arabic interviews. Likewise, they show that Arabic interviewers adopt a less adversarial questioning style compared to their global counterparts, and that aggressive questioning contributes to higher equivocation rates. Furthermore, the coded responses vary between the two interview settings.
Setting boundaries between crime and rights
Authors: Cheng Le , Zhu Xiaobin 
Published: August 2024

Abstract
In 2022, the U.S. Supreme Court’s ruling on Dobbs v. Jackson overturned two precedents, thus
ending American women’s 50-year-old constitutional right to abortion. Drawing on Van Leeuwen’s legitimation framework and Labov’s
model of narrative structure, this study focuses on how justices (de)legitimate abortion rights in contrasting narratives in
Dobbs through authorization, moral evaluation, rationalization, and mythopoesis. Specifically, we propose a
theoretical model of judicial narrative strata to deconstruct the language of justices and explain how judicial narratives set
boundaries between two different moral economies around abortion and realize the transformation of a conceived right into a
punishable crime. Furthermore, this study suggests that in the post-Dobbs era, the justices’ narrative
reconfiguration of moral boundaries may turn into social boundaries and trigger more gender segregation, which might also have
theoretical and practical implications for legislation and judicial practices in other jurisdictions.
Gradient conformal stationarity and the CMC condition in LRS spacetimes
Authors: Amery G , S Dunsby P K , Sherif A M 
Published: August 2024

Abstract
We study the existence of gradient conformal Killing vectors (CKVs) in the class of locally rotationally symmetric (LRS) spacetimes which generalizes spherically symmetric spacetimes, and investigate some implications for the evolutionary character of marginally outer trapped surfaces. We first study existence of gradient CKVs via the obtention of a relationship between the Ricci curvature and the gradient of the divergence of the CKV. This provides an alternative set of equations, for which the integrability condition is obtained, to analyze the existence of gradient CKVs. A uniqueness result is obtained in the case of perfect fluids, where it is demonstrated that the Robertson–Walker solution is the unique perfect fluid solution with a nonvanishing pressure, admitting a timelike gradient CKV. The constant mean curvature condition for LRS spacetimes is also obtained, characterized by three distinct conditions which are specified by a set of three scalars. Linear combinations of these scalars, whose vanishing define the constant mean curvature condition, turn out to be related to the evolutions of null expansions of 2-spheres along their null normal directions. As such, some implications for the existence of black holes and the character of the associated horizons are obtained. It is further shown that dynamical black holes of increasing area, with a non-vanishing heat flux across the horizon, will be in equilibrium, with respect to the frame of the conformal observers.
Research on gear flank surface defect detection of automotive transmissions based on improved YOLOv8
Authors: Yuan Haibing , Yang Yiyang , Guo Bingqing , Zhao Fengsheng , Zhang Di , Yang Shuai 
Published: August 2024

AbstractIn industrial production, the manufacturing processes may introduce defects on the gear flanks of transmission gears, potentially leading to premature failures and diminished performance. The early detection and precise assessment of surface defects on transmission gear flanks are critical for maintaining the safety, reliability, and cost-effectiveness of automobiles. At present, the principal approach for identifying defects on automotive transmission gear flanks predominantly involves manual visual inspections, supplemented by fluorescent magnetic particle testing. However, this approach suffers from low accuracy and efficiency. Consequently, this paper presents a defect detection algorithm that leverages an enhanced YOLOv8 model to facilitate the efficient detection of surface defects on automotive transmission gear flanks. Initially, the collected image data underwent data augmentation and exploratory analysis, which informed targeted enhancements. Subsequently, the YOLOv8 algorithm was thoroughly examined. The spatial pyramid pooling layer efficient architecture was incorporated into the backbone network, and the Deformable Convolutional Networks v4 module was integrated to boost the model’s capability in detecting irregular defects. In the neck network, the BiFormer attention mechanism was implemented to enhance detection performance for small-scale defects. Moreover, the newly developed modified adaptive structure feature fusion MASFF_Head structure was adopted as the detection head to augment detection efficacy for multi-scale defects. Additionally, the bounding box loss function was substituted with the Wise-Intersection over Union (WIoU) loss function to improve performance on low-quality samples. Experimental results demonstrated that the mean average precision (mAP@0.5) of the refined YOLOv8 network model reached 86.1%, marking a 2.8% increase over the original model and significantly boosting detection accuracy. When compared to other deep learning models, the enhanced YOLOv8 model exhibits considerable superiority in terms of detection precision and efficiency. The precision (P) value and recall (R) value achieved were 82.9% and 80.8%, respectively, with a detection time of 21.6 milliseconds. This underscores the method’s effectiveness and reliability in detecting automotive transmission gear defects, underscoring its pivotal role in facilitating automated detection processes on industrial production lines.
Model modification and influence of edge effect on effective area of giant electro-rheological polishing using plate electrodes
Authors: Ai Haihong , Ren Pingfa , Wang Kun , Song Tianqi , Wang Zhanshan 
Published: August 2024

Abstract
Giant electro-rheological polishing (GERP) is recognized as an innovative ultra-precision machining technology with significant potential. However, the pronounced edge effect within the GERP’s polishing gap can introduce errors in calculating the effective area and designing the electrode structure. This, in turn, may lead to under-polishing and an increased risk of insulation breakdown. In this study, COMSOL was employed to investigate the electric field distribution characteristics within the polishing gap. This exploration aimed to refine the calculation model of the effective area, optimize the plate electrodes’ structure and size, and diminish the likelihood of insulation breakdown. Through systematic finite element simulations, the impact of polishing voltage, inter-electrode gap, and plate length on the edge effect was thoroughly analyzed to ascertain its influence range. The simulation findings revealed that, while maintaining a constant inter-electrode gap for the tool electrode, variations in the polishing gap, polishing voltage, and plate length within specific ranges resulted in an edge effect influence range of approximately 1 mm. Moreover, when the machining gap, polishing voltage, and plate length remained unchanged, the edge effect influence range increased proportionally with the electrode gap within a specific range, approximately equivalent to the size of the electrode gap. Experimental validation of the giant electro-rheological effect confirmed the existence and influence range of the edge effect, aligning with the finite element simulation results. Ultimately, modifications to the calculation model of the effective area were proposed, along with a solution to optimize the electrode size and structure, with the objective of reducing the probability of insulation breakdown. In practical applications, this work can provide a valuable reference for electrode structure design, insulation breakdown improvement and parameter selection.

Authors: Wang Ruolin , Liu Haiwen , Kuang Jiaxin , Tian Hongliang , Wang Sidong 
Published: August 2024

Abstract
The design of tunable dual-narrowband high-temperature superconducting (HTS) filter based on coding superconducting metamaterials aided by grey wolf algorithm (GWA) is proposed in this paper. By virtue of the characteristics of right/left-handed bands and scale of deep sub-wavelength, the tunable metamaterials unit loaded with varactor is designed, with coupling types of coding pairs further studied. A tunable sixth-order HTS filter circuit is then constructed, whose layout is effectively optimized by newly developed GWA method. Simulated frequency responses demonstrate that the center frequencies of dual-band respectively locate at 170.1–177.2 MHz (Band I) and 185.2–194.1 MHz (Band II), with 3 dB fractional bandwidth of 0.65%–0.61% and 0.62%–0.57%. The deeply miniaturized circuit size is 0.037 × 0.046 λ2g, and the close-to-band rejection level reaches 80 dB. Experimental results of fabricated prototype measured at 70 K validate the feasibility of described design method for high order tunable HTS filter.
Field theory of active Brownian particles with dry friction
Authors: Zhang Ziluo , Yuan Shurui , Komura Shigeyuki 
Published: August 2024

Abstract
We present a field theoretic approach to capture the motion of a particle with dry friction for one- and two-dimensional (2D) diffusive particles, and further expand the framework for 2D active Brownian particles. Starting with the Fokker–Planck equation and introducing the Hermite polynomials as the corresponding eigen-functions, we obtain the actions and propagators. Using a perturbation expansion, we calculate the effective diffusion coefficient in the presence of both wet and dry frictions in a perturbative way via the Green–Kubo relation. We further compare the analytical result with the numerical simulation. Our result can be used to estimate the values of dry friction coefficient in experiments.
Condensate formation in a chiral lattice gas
Authors: Wang Boyi , Jülicher Frank , Pietzonka Patrick 
Published: August 2024

Abstract
We investigate the formation of condensates in a binary lattice gas in the presence of chiral interactions. These interactions differ between a given microscopic configuration and its mirror image. We consider a two-dimensional lattice gas with nearest-neighbour interactions, to which we add interactions involving favoured local structures (FLSs) that are chiral. We focus on FLSs that have the shape of the letter L and explore condensate formation through simulations and analytical calculations. At low temperature, this model can exhibit four different phases that are characterised by different periodic tiling patterns, depending on the strength of interactions and the chemical potential. When particle numbers are conserved, some of these phases can coexist. We analyse the structure and surface tension of interfaces between coexisting phases and determine the shapes of minimal free energy of crystalline condensates. We show that these shapes can be quadrilaterals or octagons of different orientation and symmetry.
Fisheye Night Sky Imager: A Calibrated Tool to Measure Night Sky Brightness
Authors: Hung Li-Wei , White Jeremy , Joyce Damon , Anderson Sharolyn J , Banet Benjamin 
Published: August 2024

Abstract
The Night Skies Team of the U.S. National Park Service (NPS) has developed a new camera system equipped with a fisheye lens to measure night sky brightness. This NPS Fisheye Night Sky Imager comprises a back-illuminated Sony IMX455 CMOS sensor housed in the ZWO ASI6200MM camera, a Johnson V filter, and a Sigma 8 mm F3.5 fisheye lens. All of the components are commercially available. The fisheye lens allows us to capture the entire sky in a single frame. The wide-angle view also introduces calibration challenges. To address this, we have customized tools and devised innovative methods for calibrating the system, including flat-field correction, pixel scale determination, and field of view characterization. Additionally, we use standard stars for precise positional and photometric calibration. Furthermore, we create an open-source Python pipeline to process these fisheye images and leverage Git and GitHub for source code version control and distribution. The resulting images provide a positionally and brightness-calibrated fisheye view of the night sky, with a photometric calibration uncertainty of 0.12 mag. When comparing our Fisheye Night Sky Imager measurements to images taken with other calibrated systems, we reliably achieve consistent results under both dark and bright skies. Our Fisheye Night Sky Imager not only enables rapid assessment of sky quality but also supports the feasibility of establishing permanent monitoring locations. Recognizing that the natural dark sky is a critical element for natural, cultural, educational, and visitor experiences, this new camera system enhances our ability to assess resource conditions and fulfill the NPS mission of conserving resources unimpaired for the enjoyment of this and future generations.

Authors: Edler F , Ederer P , Huang K 
Published: August 2024

Abstract
An electromotive force–temperature reference function for thermocouples made of platinum–20%rhodium versus platinum (Pt–20%Rh/Pt) was determined for the temperature range from 0 °C to 1100 °C. Three Pt–20%Rh/Pt thermocouples were constructed at the Physikalisch-Technische Bundesanstalt (PTB) and were compared with standard platinum resistance thermometers, an Au/Pt thermocouple and a Pt/Pd thermocouple, which were all calibrated at fixed points of the International Temperature Scale of 1990 (ITS-90). The comparison measurements were performed in stirred liquid baths in the range from 0 °C to 545 °C, in a sodium heat pipe from 560 °C to 980 °C, and in a five-zone furnace at temperatures between 1000 °C and 1100 °C. Furthermore, the Pt–20%Rh/Pt thermocouples were calibrated at fixed points of the ITS-90. The PTB reference function based on two of the three Pt–20%Rh/Pt thermocouples has an expanded measurement uncertainty of 0.25 K in the temperature range from 0 °C to 1100 °C.

Published: August 2024

Abstract
Sustainable urban Stormwater Management (SSM) is currently widely implemented globally to support urban flood management efforts. It is commonly known by terms such as Green Infrastructure (GI), Best Management Practice (BMP), Sustainable Urban Drainage System (SUDS) or Low Impact Development (LID). However, in Vietnam, these approaches are still relatively new and have not been widely adopted due to various barriers, including community perception. Therefore, this study conducted a preliminary social survey in the Thu Duc City area to gain a deeper understanding of perspectives, knowledge, and support for SSM practices. The results showed that among the surveyed residents, 78% favored a centralized stormwater management manner (e.g., retention/detention ponds,…), 51% preferred a decentralized manner (e.g., rain gardens, infiltration trenches,…) and 45% considered household-level practices (e.g., green roofs, rain barrels,…). Additionally, when asked about financial contributions towards implementing these practices, approximately 70% did not support the idea, and 50% believed it was the government’s responsibility. The research findings highlight the diversity in urban residents’ perceptions and opinions regarding stormwater management. This study provides essential foundational information for the development of policies and strategies to effectively promote SSM practices, aiming to mitigate urban flooding and contribute to environmental protection.

Published: August 2024

Abstract
The population growth rate of Cianjur Regency, Indonesia, continues to increase with an annual growth rate of 1.26%. This population growth has consequences to the need of land requirement for settlements, so that the conversion of agricultural land is inevitable. To reduce the rate of the conversion, it can be pursued through the utilization of less productive land into multifunctional productive land, for example by building agro-tourism. One of the lands that has not been optimally utilized is a 3 hectare agricultural land owned by Tjikoepa Inn in Sukanagara, Cianjur Regency. The purpose of this research is to design the less productive of agricultural land into an agrotourism landscape that can meet the lodging and tourism needs of Cianjur Regency. The method used in this research is the description method through an approach of program-based landscape design. Agricultural activities and commodities are determined by the land owner. The design concept adopted is modern integrated agricultural tourism by considering low external input and sustainable agriculture (LEISA) that can maximize the potential of integrated farming that is educative and provides a more inspiring and fun experience for visitors ranging from children to adults. The space formed includes service area, culinary tourism area, agricultural tourism area (horticulture, plantations, livestock, and fisheries), outbound area, glamping area, conservation area, and place of view point. Visitors are pampered with all their senses along the way starting from the parking lot upto the highest level at the place of view point.
