Abstract
Background
The main purpose of this paper is to introduce a method that can accurately locate the posterior capsule of the lens to facilitate a relatively complete resection of the anterior vitreous body.
Methods
A total of 51 patients in the experimental group and control group were enrolled in this study. Phacoemulsification combined with vitrectomy was performed in all cases. After the cataract procedure was completed in the control group, the surgeon performed a conventional anterior vitrectomy with the operative eye. In the experimental group, anterior vitrectomy was performed according to the threadiness corrugation of the posterior capsule of the lens. During the operation, with the help of triamcinolone, two surgeons confirmed the resection of the anterior vitreous cortex; the best corrected visual acuity and intraocular pressure of all patients were recorded at 1 week, 1 month and 3 months after surgery.
Results
Fifty patients underwent phacoemulsification combined with vitrectomy, except one patient in the experimental group who was lost to follow-up. After surgery, no significant complications were observed in all patients except two patients in the control group with temporary increases in intraocular pressure. There was no significant difference in preoperative visual acuity between the two groups (t = 0.83, P = 0.25). Both groups had varying degrees of improvement in best corrected visual acuity at 1 week, 1 month and 3 months after surgery. Moreover, there was no significant difference in BCVA between the two groups at the three follow-up time points (t=-1.15, -1.65, -1.09, P = 0.53, 0.21, 0.23). After surgery, no significant complications were observed in all patients except two patients in the control group with temporary increases in intraocular pressure. Incomplete resection of the anterior vitreous cortex was observed in 2 patients in each group, but there was no significant difference (χ2 = 7.81, P > 0.05).
Conclusion
In the process of cataract surgery combined with vitrectomy, thready corrugation appears in the posterior capsule of the lens and is an important sign of its localization. Anterior vitrectomy can be accomplished safely and effectively with the help of thread-like corrugation, and the surgical effect is almost the same as that of traditional surgery. Especially suitable for beginners in vitreous surgery.

Authors: Ahmad Shafiq , Khan Aamir Abbas 
Published: September 2023

Abstract

The present analysis focuses on a comprehensive study involving the synergistic exploration of diverse scientific concepts, encompassing micropolar trihybrid nanofluids, stagnation point flow, and second-grade fluids, with the use of expanded versions of the Fick's and Fourier's laws. Further, the influences of double stratification, viscous dissipation, activation energy, thermal radiation, and magnetohydrodynamics are incorporated. The research further extends to the implementation of the modified Fick's and Fourier’s laws, which provide a comprehensive framework for understanding heat-mass communication in such intricate systems. Using the proper similarity variables, the flow model equations are converted into their non-dimensional form. These transfer version equations are numerically resolved using MATLAB implementation of the BVP4C technique. For several emerging dimensionless parameters, the graphical and numerical results are derived and analysed. From the figures, clearly, with larger values of the 2nd -grade fluid parameters, the fluid velocity and temperature flow rapidly with the presence of ternary hybrid nanofluid in comparison to unary nanofluid.
The mediating role of flow in the relationship between simulation design and simulation educational satisfaction in Korean nursing students: A cross-sectional study
Authors: Lee Eun-Kyung , Ji Eun-Joo 
Published: September 2023

Abstract

Background
In Korea, there has been recent interest in nursing simulation education. Although students may find simulation-based teaching techniques fresh and fascinating, it is important to assess students' satisfaction with these techniques beyond their novelty value. Flow, the state of absolute immersion in a specific activity, is an important ask of simulated learning. Therefore, this study examined the mediating effect of flow on the relationships between simulation design and simulation educational satisfaction.
Method & Materials:
A cross-sectional study design was used. The participants of this study were 143 fourth-year nursing students who had participated in classes using simulations at three universities in Seoul, Daegu, and Jeonbuk. Data were collected from April 24 to May 3, 2023. Demographic data, simulation design scale, flow in simulation, and the educational satisfaction scale in simulation were collected via an online questionnaire. The data were analyzed using SPSS 25.0.
Results
Our results indicate that simulation design has a positive effect on flow and simulation educational satisfaction and flow has a positive effect on simulation educational satisfaction. Additionally, flow mediated the impact of simulation design on simulation educational satisfaction.
Conclusion
The significance of the current study lies in its confirmation of the link between simulation design and simulation educational satisfaction, as well as the mediating function of flow. Nursing students can achieve simulation educational satisfaction through simulation-based education if simulation educators follow best practices that improve flow through well-organized simulation design.

Published: September 2023

Abstract
Purpose: Sub-acute recovery-oriented facilities offer short-term residential support for people living with mental illness. They are generally highly regarded by consumers, with emerging evidence indicating that these services may support recovery. The aim of the current study was to explore the relationship between personal recovery and consumers’ satisfaction with sub-acute residential services, and consumers’ views about service features that aid recovery.
Method: Consumers at nineteen adult Prevention and Recovery Care Services in Victoria, Australia, were invited to complete measures containing sociodemographic information and measures on personal recovery and wellbeing. After going home, participants were invited to complete measures on service satisfaction and experience.
Results: Total and intrapersonal scores on the personal recovery measure increased significantly between Time 1 and Time 2, indicating marked improvement. Personal recovery and satisfaction measures were moderately to strongly correlated. Thematically analysed open-ended responses revealed themes of feeling connected, finding meaning and purpose, and self-empowerment as important aspects of these services, with some recommendations for improvements.
Conclusion: Sub-acute residential services may support individuals’ personal recovery, be preferable and more cost effective than in-patient services. Exploring consumers’ experiences of sub-acute residential services helps to understand their effectiveness, opportunities for improvement and intended impacts on personal recovery.

Published: September 2023

Abstract
To enhance the accuracy and robustness of cycle slip detection and repair for triple-frequency data while minimizing the adverse effects of low satellite elevation and ionospheric scintillation, a hierarchical combination algorithm for real-time cycle slip detection and repair is proposed. This algorithm begins by prioritizing the reduction of noise and ionospheric delay coefficients. It determines the optimal coefficients for the combination of observations from the BeiDou Navigation Satellite System's (BDS) Extra-Wide Lane (EWL), Wide Lane (WL), and Narrow Lane (NL). Leveraging the longer wavelength characteristics of the EWL combination, it simultaneously conducts cycle slip detection on the EWL combination alongside pseudo-range combinations. Following this, based on the detection outcomes from the EWL combination, cycle slip detection is carried out on the WL combination. Finally, using the detection findings from the WL combination, cycle slip detection is executed on the NL combination. Given the NL combination's shorter wavelength and higher susceptibility to ionospheric delay, a dynamic ionospheric prediction model is applied to the NL combination to further mitigate the impact of ionospheric disturbances. After completing the cycle slip detection process, the results from the EWL, WL, and NL combinations are integrated and solved. Experimental results clearly demonstrate that, even in scenarios characterized by low satellite elevation and active ionospheric conditions, this algorithm consistently delivers outstanding detection performance for cycle slip instances, particularly for small cycle slip(less two cycle). Remarkably, this performance is achieved without the need for intricate searches during cycle slip repair. In comparison to conventional combination methods, this algorithm significantly enhances the accuracy of cycle slip repair, improving it by an impressive 42.2%.

Abstract
The purpose of this study was to screen Copy Number Variations (CNVs) in 35 unsolved Inherited Retinal Dystrophy (IRD) families. Initially, Next generation sequencing, including a specific Hereditary Eye Disease Enrichment Panel or Whole exome sequencing, was employed to screen (likely) pathogenic Single-nucleotide Variants (SNVs) and small Insertions and Deletions (indels) for these cases. All available SNVs and indels were further validated and co-segregation analyses were performed in available family members by Sanger sequencing. If not, after excluding deep intronic variants, Multiplex ligation-dependent probe amplification (MLPA), quantitative fluorescence PCR (QF-PCR) and Sanger sequencing were employed to screen CNVs. We determined that 18 families who had heterozygous SNVs/indels or whose parents were not consanguineous but had homozygous SNVs/indels in autosomal recessive IRDs genes had CNVs in another allele of these genes, 11 families had disease-causing hemizygous CNVs in X-linked IRD genes, six families had (likely) pathogenic heterozygous CNVs in PRPF31 gene. Of 35 families, 33 different CNVs in 16 IRD-associated genes were detected, with PRPF31, EYS and USH2A the most common disease-causing gene in CNVs. Twenty-six and seven of them were deletion and duplication CNVs, respectively. Among them, 14 CNVs were first reported in this study. Our research indicated that CNVs contribute a lot to IRDs, and screening of CNVs substantially increases the diagnostic rate of IRD. Our results indicate that MLPA and QF-PCR are ideal methods to validate CNVs, and the novel CNVs reported herein expand the mutational spectrums of IRD.

Published: September 2023

Abstract
Collagen, as the additive during the process of Electrodeposition of Copper, commonly used to be a leveling agent in the production of electrolytic copper foil (ECF), is effective in refining grain and enhancing mechanical properties of copper foil. However, hydrolysis and electrodeposition cause the loss of collagen may easily arise fluctuation of the additive composition, thus affect the quality of copper foil. For improving the production stability of ECF, it is necessary to explore the hydrolysis properties and mechanism of collagen during copper electrodeposition. Here, we research the efficacy of action and hydrolysis properties of collagen during copper electrodeposition by means of a combination of real-time monitoring and multiple analysis, at the same time, explore the evolution behavior of microstructure, mechanical properties and electrical conductivity in the hydrolysis process of collagen. By the hydrolysis and adsorption of collagen, a significant inhibitory deposition process during copper electrodeposition occurs. Importantly, the inhibitory effect and content of collagen showed a power-index relationship. With the prolongation of hydrolysis time or the volum increase of copper deposition, the hydrolysis rate of collagen decreased sensibly. More, with the addition of collagen, the prepared ECF exhibited a microstructural transformation and its mechanical properties also changed significantly. Therefore, our work reveals the hydrolysis properties and mechanism of collagen in copper foil electrodeposition, which provides an important theoretical reference for the development and application of high performance copper foil.

Authors: Tian Zeyu 
Published: September 2023

Abstract
Let the computer apprehend and describe the representation of the relative position between objects of the image by the way of the common intuition of the human is an important task of the computer vision and pattern recognition. To complete this task, the position sensing parameter and histogram of position sensing forces are proposed in this paper. The position sensing parameter can represent the spatial relative position of the point with regard to the reference object, and the point is from the argument object. The histogram of position sensing forces is composed of the position sensing parameter of each point in the argument object and the gravitational forces between each point of the argument object and each point of the reference object. The histogram of position sensing forces can simulate the human perception for the directional spatial relations between the argument object and reference object of the image, considering the shape, size, angular and metric information of the spatial object.
Assigning Patients to Healthcare Centers Using Dispatching Rules
Authors: Teymourifar Aydin , Trindade Maria A. M. 
Published: September 2023

Abstract
This study proposes a model for the balanced assignment of patients to healthcare centers in a region. In the suggested model, it is supposed that patients want to go to the nearest center, which causes an imbalance in the workloads of resources between centers. This disproportion is undesirable not only for the centers but also for the patients. Thus, balancing assignments is targeted. This goal is expressed in a model with a multi-objective function. Since balancing is one of the main goals of the sectorization concept, we characterize the model based on it. Unlike studies in the literature, we do sectorization employing dispatching rules. This diminishes the problem's complexity and makes it suitable for solving actual, large, and dynamic problems. We simulated the system using the Rockwell Arena software. We consider the effect of different seasons, days, and hours on the system. The dispatching rule used for sectorization is optimized using the OptQuest software. The numerical results demonstrate that by optimizing the dispatching rule, it is possible to enhance the objective function significantly.

Authors: Kharchich Fatima Zahra , Khamlichi Abdellatif 
Published: September 2023

Abstract

The two-terminal III-V/Si double junction solar cells were recognized to achieve comparable performance with lower cost of fabrication than the III-V/III-V tandems. They have already yielded an efficiency of 35.9% of power conversion. However, this performance still remains below the theoretically limit which is stated to be beyond 43%. Considering monolithic InGaP/Si based tandem designed with double back surface field layers, this work dealt with optimization of efficiency as a function of the structure layers thicknesses and dopings. Numerical simulations were conducted for this purpose by using Silvaco/ATLAS TCAD software and were sorted according to a multi-step optimization procedure. The obtained optimum tandem InGaP/Si solar cell reached an unprecedented power conversion efficiency of 38.16% under 1.5G spectrum. Furthermore, a realistic analysis of performance of this structure was performed under different temperatures and illumination levels. The effect of InGaP band gap variation on efficiency was also investigated.

Published: September 2023

Abstract

In quantum information theory, symmetric informationally complete positive operator-valued measures (SIC-POVMs) are related to quantum state tomography, quantum cryptography and foundational studies. It is difficult to construct SIC-POVMs and remains unknown whether SIC-POVMs exist for infinitely dimension. Therefore, researchers have proposed the solution to construct approximately symmetric informationally complete positive operator-valued measures (ASIC-POVMs). This paper proposes a construction of ASIC-POVMs using character sums over Galois rings. The dimension of this ASIC-POVMs is q-1, where q is a prime power. Also, our constructions include partial results about ASIC-POVMs constructed by X. Cao et al (X. Cao, J. Mi and S. Xu: Two constructions of approximately symmetric informationally complete positive operator-valued measures. J. Math. Phys., 58(6), 062201 (2017)).

Abstract
The manufacture of silver nanoparticles using plant extract is a simple, worthwhile, and ecologically friendly method. We present the use of in this study Crocus sativus .L petal extract is being used to create environmentally friendly nanoparticles. In the green approach, UV-Vis spectroscopy is utilised to characterise and confirm the presence of silver nanoparticles containing reduced silver ions. The XRD confirms the silver nanoparticles' crystalline structure formed in this process. Scanning electron microscopy reveals predominantly spherical and triangular shapes of the nanoparticles, with sizes ranging from 20 to 45 nm. To examine electrochemical properties, cyclic voltammetry and electrochemical impedance studies were utilised. Consequently, when subjected to the disc diffusion method, the synthesized silver nanoparticles exhibit enhanced antibacterial activity [1] against various strains such as Pseudomonas aeruginosa, Proteus vulgaris, Enterococcus faecalis, Streptococcus Mutans, Enterococcus aeruginosa, and Bacillus subtilis.
Visual Analytics for NASCAR Motorsports

Published: September 2023

Abstract
The National Association of Stock Car Auto Racing (NASCAR) is consistently ranked among the top ten most popular sports in the United State1,2 . It is the most lucrative, generating an estimated $3 billion annually3 . Teams are financially well-supported and competitive in all areas where an advantage might be gained. NASCAR events are characterized by on-track racing punctuated by pit stops since cars must refuel, replace tires, and modify their setup throughout a race. A well-executed pit stop can allow drivers to gain multiple seconds on their opponents. Strategies around when to pit and what to perform during a pit stop are under constant evaluation. One currently unexplored area is publically available communication between each driver and their pit crew during the race. Due to the many hours of audio, manual analysis of even one driver’s communications is prohibitive. We propose a fully automated approach to analyze driver–pit crew communication. Our work was conducted in collaboration with NASCAR domain experts—a simulation manager, a crew chief, and a software engineering manager—to validate our findings. Audio communication is converted to text and summarized using cluster-based Latent Dirichlet Analysis (LDA) to provide an overview of a driver’s race performance. The transcript is then analyzed to extract important events related to pit stops and driving balance: whether a car is understeering (pushing) or oversteering (over-rotating). Named entity recognition (NER) and relationship extraction provide context to each event. A combination of the race summary, events, and real-time race data provided by NASCAR are presented using Sankey visualizations. Statistical analysis and evaluation by our domain expert collaborators confirmed we can accurately identify important race events and driver interactions, presented in a novel way to provide useful, 1 important, and efficient summaries and event highlights for race preparation and in-race decision-making.
