Published: July 2024

AbstractMeniscus repair has increased in frequency, especially among surgeons who focus on youth sports injuries. The aim of this study was to determine current trends in meniscus repair among a specific subset of meniscus repair surgeons. A cross-sectional survey utilizing several clinical vignettes was administered to orthopaedic surgeon members of the Pediatric Research in Sports Medicine (PRiSM) Society to investigate surgeon experience and training, number of meniscus repair procedures performed, and surgical and rehabilitation preferences. A statistical analysis of the responses was performed to determine associations between years in practice or type of fellowship training and the number of meniscus repair procedures performed, surgical indications, and rehabilitation preferences. The response rate to various questions ranged from 61.5 (59/96) to 63.5% (61/96). In all vignettes, a majority favored repair as well as some degree of weight-bearing and range-of-motion restrictions. Surgeons who had been in practice for 6 to 10 years performed significantly more meniscus repairs per year than those who had been in practice for greater than 20 years (p = 0.009) and those who had been in practice for 0 to 5 years (p = 0.05). Surgeons who had been in practice for greater than 20 years performed a significantly higher percentage of meniscectomies relative to meniscus repairs, compared with those in practice for 0 to 5 years (p = 0.002) or 6 to 10 years (p = 0.0003). When surgeons were grouped into those with less than 10 years of experience and those with greater than 10 years of experience, the former group performed a significantly higher number of meniscus repairs relative to meniscectomies than the latter group of surgeons (p < 0.0001). Less experienced surgeons are more likely to perform meniscus repair than meniscectomy, but all surgeons surveyed had a general preference for repair in all clinical vignettes. Repair technique preferences as well as rehabilitation protocols varied widely among surgeons.

Published: July 2024

AbstractCholangiocarcinoma (CCA) is a malignancy of epithelial cells in the bile duct, categorized based on its anatomical location as intrahepatic, perihilar, or extrahepatic. It has a low prevalence of ∼1.6 cases per 100,000 people in the United States, but has a poor prognosis. All stages included, CCA has a 5-year survival rate of less than 10%. The preferred curative treatment for intrahepatic, perihilar, and extrahepatic CCA is surgical resection combined with systemic chemotherapy. However, resection is not always a viable option for many patients, as the disease is often discovered at the time of diagnosis to be either metastatic or locally advanced precluding surgical resection. In this setting, a variety of options can be used, one of which is radiation therapy (RT). The administration of RT has evolved tremendously over the past decades. Total doses given can be limited by a tumor's proximity to regional normal organs such as the liver, stomach, bile duct, and small and large bowel. When a CCA is unresectable, it is often in close proximity to radiosensitive organs. Delivering RT in this setting therefore requires precise delivery techniques. An emerging technique known broadly as stereotactic body radiation therapy (SBRT) or stereotactic ablative body radiation therapy gives a highly focused, often ablative, form of RT to a defined and specific target. Categorically, SBRT offers a quick and efficient management option, in some cases only one to three total treatments. This narrative reviews various applications of SBRT for cholangiocarcinoma including SBRT alone, SBRT with chemotherapy, SBRT with chemotherapy followed by a liver transplantation (orthotopic liver transplantation), and finally novel combinations of SBRT with immunotherapy.
Advancing criminal justice through mediation: analyzing the integration of mediation in Emirati criminal legislation
Authors: Alnuaimi Ahmed Ali , Alkrisheh Mohammad Amin 
Published: July 2024

AbstractCriminal mediation is viewed as a promising alternative to traditional judicial procedures for resolving criminal disputes, offering a novel approach to alleviating burdens on the judicial system. This study examines the integration of mediation into Emirati criminal legislation, focusing on its potential to improve dispute resolution outcomes and reduce judicial workload. The UAE law has incorporated criminal mediation in the new amendment to the criminal procedures law by Federal Decree-Law No. 38 of 2022. This research aims to elucidate the provisions of criminal mediation and how it is organized within the UAE legal system. Employing an analytical descriptive methodology, the study explores the legal frameworks and procedural nuances of criminal mediation. It demonstrates how it can significantly mitigate the adverse effects on affected parties and decrease the recurrence of criminal behavior. The study recommends establishing a specialized training program for legal mediators, designed to equip them with the necessary skills to effectively handle diverse criminal cases, ensuring that mediation processes are conducted with the highest standards of justice and efficiency. Implementing such training programs would enhance the professionalism of criminal mediation and increase its success rates, contributing to a more effective and humane criminal justice system.

Published: July 2024

A synthetic route to the preparation of cobalt(III) complexes coordinated by bidentate phenylthioether ligands is described. Complexes of the type ((2-(X-phenylthio)ethylamine)-N,S)bis(ethylenediamine)cobalt(III) perchlorate, [(en)2Co(S(X-phenyl)CH2CH2NH2)](ClO4)3, where X = 4-methoxy (2a), 4-methyl (2b), 3-methyl (2c), nothing (2d), 3-methoxy (2e), 4-bromo (2f) and 3-bromo (2g) were prepared. The synthetic route involves reaction of trans-dichloridobis(ethylenediamine)cobalt(III) chloride with NH2CH2CH2SC6H4X to produce cis-[(en)2CoCl(NH2CH2CH2SC6H4X)]Cl2 (1a–g). Formation of the Co–S bond, completing the ring closure, is then accomplished by removing the coordinated chlorido by addition of AgClO4 in sulfolane. Complexes were characterized by 1H and 13C NMR spectroscopy, UV-Vis spectroscopy and elemental analysis. In addition, the solid-state structure (X-ray) of the monohydrate of 2d confirms the coordination mode of the ligand. Preliminary kinetic investigations in basic solution show that the Co–S bond is broken resulting in the formation of [(en)2Co(OH)(NH2CH2CH2SC6H4X)]2+. At 15.0°C, a Hammett Plot is linear (r2 = 0.981) with ρ = 2.24 ± 0.13.
Ray tracing through absorbing dielectric media in the Schwarzschild spacetime
Authors: Rogers Adam 
Published: July 2024

Abstract
General Relativity describes the trajectories of light-rays through curved spacetime near a massive object. In addition to gravitational lensing, we include an absorbing dielectric medium given by a complex refractive index known as the Drude model. When absorption is included the eikonal becomes complex, with the imaginary part related to the absorption along a ray between emission and observation points. We extend results from the literature to include dispersion in the index of refraction. The complex Hamiltonian splits into a real part that describes the equations of motion and a constraint equation that governs the momentum loss in the system. We work in coordinates which are fully real, with a real metric in physical spacetime. We assume the dust and plasma distributions of the Drude matter to coincide and vary as a power-law

. We find that transmission requires h > 1, otherwise exponential absorption occurs along ray paths. We use ray-tracing through strongly absorbing matter near the surface of the compact star, as well as specializing to a point-lens in the weak-field limit with weakly absorbing matter to generate potentially observable light curves for distant observers. In the appropriate limits, our theory reproduces results from the literature.

Abstract
The development of artificial optoelectronic synapses utilizing flexible, and transparent oxide transistors is crucial for advancing neuromorphic computing and wearable electronics. Here, we propose artificial optoelectronic synapses on flexible and transparent devices based on an ion-gel gated oxide transistor. The device consists of indium-tin-oxide/ion-gel thin film conformity fabricated on a polyethylene terephthalate substrate. The device exhibited a loop opening in current–voltage properties, and its operating mechanism was ascribed to charge trapping and de-trapping. The neuromorphic behaviors can also be simulated by this device for instance, namely ultraviolet (UV) induced short-term memory, long-term memory, paired-pulse facilitation, and learning/forgetting behaviors. Additionally, electrical habituation and UV potentiation were executed. This work paves the way for the realization of low-cost flexible and transparent synaptic wearable electronics.
Study on the effect of heat treatment on the structure, mechanical and electrical properties of alumina fiber insulation
Authors: Xie Li , Han Yongjin , Huang Yang 
Published: July 2024

Abstract
In this paper, the heat treatment of alumina fiber was studied. The infiltration agent on the fiber surface was removed after heat treatment at 450 °C for 6 h. TG-DSC, scanning electron microscope, x-ray diffraction, Fourier infrared spectrometer, energy dispersive spectrometer, and patterning were used to analyze the thermal weight loss, fiber surface morphology, crystal structure, and composition of alumina fibers. The results show that the aluminum oxide fiber has excellent temperature resistance and does not undergo crystal phase transformation during thermal weight loss. After heat treatment, the fiber surface infiltration agent ablates and dissolves from the fiber surface, and the internal crystal structure of the fiber remains stable. The tensile testing machine was utilized to test the breaking strength of alumina fiber. The fiber still maintained high strength after heat treatment, and the retention rate of breaking strength was greater than 74%. ZC-90G high insulation resistance measuring instrument and WDY-Ⅱ automatic voltage tester were utilized to analyze the insulation resistivity and breakdown strength of alumina fiber before and after heat treatment. The results show that heat treatment can effectively improve the insulation performance and breakdown strength of alumina fiber.

Published: July 2024

Abstract
Model-free adaptive control (MFAC) stands out as an effective data-driven method for addressing nonlinear problems in industrial processes. To maintain good control performance, a data-driven set-point tuning (DDST) method is used to update the virtual set-point of the MFAC system. The DDST-based MFAC (i.e. DDST-MFAC) constantly approaches the target of the process through the nonlinear set-point tuning method. However, due to equipment errors and external interference, industrial sensors often suffer from measurement noise, which can have adverse effects on the control performance. In this article, an available dynamic data reconciliation technique is adopted to improve the tracking performance of the DDST-MFAC, which suppresses the impact of process noise by using predicted information and measured data to achieve high-precision requirements for controlling nonlinear processes. Finally, considering both Gaussian and non-Gaussian distribution of measurement noise, the effectiveness of the proposed method was verified through the simulation of a nonlinear nonaffine plant. It is also applied to the steam-water heat exchange process, the control result is improved ultimately.
Multi-factor quality assessment of digital speckle pattern for speckle projection profilometry

Published: July 2024

Abstract
The digital speckle pattern (DSP) is an essential component in the speckle projection profilometry (SPP) task, its quality directly affects the results of three-dimensional (3D) shape reconstruction. However, the SPP field lacks specialized numerical metrics for evaluating speckle quality. To address this issue, this study introduces a multi-factor metric (MFM) for comprehensive DSP assessment. Through comparing the metric, optimal parameter ranges for DSP design and the advisable matching subset size can be determined for SPP algorithm. A global indicator named valid feature distribution (VFD) based on scale-invariant feature transform (SIFT) and Delaunay triangulation, is defined to analyze the overall information distribution in DSPs. In addition, MFM incorporates a local metric called mean subset intensity gradient (MSIG), which aids in selecting the suitable radius for different DSPs to balance the accuracy and efficiency. The quality assessment targets the speckle scene images, allowing for the reverse adjustment of the most suitable DSP according to different scenes. The performance of DSPs can be evaluated based on the accuracy and completeness of 3D reconstruction results. By conducting simulation experiments on the 3ds Max platform, the recommended parameter range for DSP can be inferred, including speckle density ratio, speckle diameter, and random variation rate. Appropriate subset sizes for different scenes are also investigated. Furthermore, the MFM is verified on a real binocular speckle device, demonstrating that the measurement standard deviation of a complex workpiece can be reduced to 0.078 mm using the recommended DSP.

Abstract
Our research efforts in displacement measurement interferometry focused on long-term drifts initiated an extended experimental investigation in the interferometric assemblies of our design. We aimed to analyze, characterize and tackle the long-term measurement stability, expressed as the zero-drift, with particular attention to the thermal effects. For the experimentation, we developed a thermostatic chamber equipped with active temperature regulation, an array of sensors and control electronics. With either the finely stabilized temperature or with the thermal cycling, we can carry out a range of investigations: verification of modified design or prototype interferometers, testing of production pieces, characterization of integrated assemblies and units in terms of the zero drift and the susceptibility to thermal effects—the temperature sensitivity (

Precipitable water vapor retrieval for rainfall forecasting using BDS-3 PPP-B2b signal in the coastal region of China
Authors: Xu Ying , Zhao Panpan , Wang Jin 
Published: July 2024

Abstract
Currently, rainfall cannot be accurately forecast because of poor network communication at the ocean. The advantage of the BeiDou Global Navigation Satellite System (BDS-3) precise point positioning (PPP-B2b) signal, which does not rely on network communication to receive data, is that it can provide precipitable water vapor (PWV) retrieval application services for the open seas in eastern China, where the communication system presents difficulties. In this study, data from stations in the coastal region of China were used to establish a rainfall forecasting method for monitoring extreme weather on the sea. First, the service performance of PPP-B2b was explored. Then, based on 17 Chinese coastal stations, the PWV accuracy was evaluated. Finally, based on an analysis of the relationship between PWV and actual rainfall, a threshold rainfall forecasting method based on a sliding window was constructed. The experimental results show that the PWV accuracy varies slightly depending on the geographic location, in which the mean absolute error in the North Sea region is the smallest (2.1 mm), that of the South China Sea region is the largest (2.60 mm), and that of the East China Sea region is in the middle (2.48 mm). The optimal predictors of the constructed 12 h sliding-window threshold rainfall prediction method are a PWV maximum of 49 mm, PWV increase of 5 mm, and PWV increase rate of 1.2 mm h−1. The prediction results can reach a critical success index value of more than 45%, indicating high prediction accuracy and applicability to the coastal region of China during the same period.
Stable/unstable holonomies, density of periodic points, and transitivity for continuum-wise hyperbolic homeomorphisms
Authors: Carvalho B , Rego E 
Published: July 2024

Abstract
We discuss different regularities on stable/unstable holonomies of cw-hyperbolic homeomorphisms and prove that if a cw-hyperbolic homeomorphism has continuous joint stable/unstable holonomies, then it has a dense set of periodic points in its non-wandering set. For that, we prove that the hyperbolic cw-metric (introduced in Artigue et al (2024 J. Differ. Equ.
378 512–38)) can be adapted to be self-similar (as in Artigue (2018 Ergodic Theory Dyn. Syst.
38 2422–46)) and, in this case, continuous joint stable/unstable holonomies are pseudo-isometric. We also prove transitivity of cw-hyperbolic homeomorphisms assuming that the stable/unstable holonomies are isometric. In the case the ambient space is a surface, we prove that a cw

-hyperbolic homeomorphism has continuous joint stable/unstable holonomies when every bi-asymptotic sector is regular.

Abstract

Objective. To allow the estimation of secondary cancer risks from radiation therapy treatment plans in a comprehensive and user-friendly Monte Carlo (MC) framework. Method. Patient planning computed tomography scans were extended superior-inferior using the International Commission on Radiological Protection’s Publication 145 computational mesh phantoms and skeletal matching. Dose distributions were calculated with the TOPAS MC system using novel mesh capabilities and the digital imaging and communications in medicine radiotherapy extension interface. Finally, in-field and out-of-field cancer risk was calculated using both sarcoma and carcinoma risk models with two alternative parameter sets. Result. The TOPAS MC framework was extended to facilitate epidemiological studies on radiation-induced cancer risk. The framework is efficient and allows automated analysis of large datasets. Out-of-field organ dose was small compared to in-field dose, but the risk estimates indicate a non-negligible contribution to the total radiation induced cancer risk. Significance. This work equips the TOPAS MC system with anatomical extension, mesh geometry, and cancer risk model capabilities that make state-of-the-art out-of-field dose calculation and risk estimation accessible to a large pool of users. Furthermore, these capabilities will facilitate further refinement of risk models and sensitivity analysis of patient specific treatment options.

Published: July 2024

Abstract

Objective. Radiation-induced acoustic (RA) computed tomographic (RACT) imaging is being thoroughly explored for radiation dosimetry. It is essential to understand how key machine parameters like beam pulse, size, and energy deposition affect image quality in RACT. We investigate the intricate interplay of these parameters and how these factors influence dose map resolution in RACT. Approach. We first conduct an analytical assessment of time-domain RA signals and their corresponding frequency spectra for certain testcases, and computationally validate these analyses. Subsequently, we simulated a series of x-ray-based RACT (XACT) experiments and compared the simulations with experimental measurements. In-silico reconstruction studies have also been conducted to demonstrate the resolution limits imposed by the temporal pulse profiles on RACT. XACT experiments were performed using clinical machines and the reconstructions were analyzed for resolution capabilities. Main results. Our paper establishes the theory for predicting the time- and frequency-domain behavior of RA signals. We illustrate that the frequency content of RA signal is not solely dependent on the spatial energy deposition characteristics but also on the temporal features of radiation. The same spatial energy deposition through a Gaussian pulse and a rectangular pulse of equal pulsewidths results in different frequency spectra of the RA signals. RA signals corresponding to the rectangular pulse exhibit more high-frequency content than their Gaussian pulse counterparts and hence provide better resolution in the reconstructions. XACT experiments with ∼3.2 us and ∼4 us rectangular radiation pulses were performed, and the reconstruction results were found to correlate well with the in-silico results. Significance. Here, we discuss the inherent resolution limits for RACT-based radiation dosimetric systems. While our study is relevant to the broader community engaged in research on photoacoustics, x-ray-acoustics, and proto/ionoacoustics, it holds particular significance for medical physics researchers aiming to set up RACT for dosimetry and radiography using clinical radiation machines.
