Design and Manufacture of Mould Free Fibre Reinforced Laminates with Compound Curvature
Authors: Jenkins Christopher , Donough Matthew J. , Prusty Gangadhara B. 
Published: December 2023

Abstract
Composite manufacturing demands mould tooling to produce dimensionally accurate parts, adding substantial capital costs to their production. Recent developments in advanced manufacturing of fibre-reinforced polymer composite elements have seen the implementation of mould-free technologies that can produce complex shaped parts off a flat tool. This paper presents eccentric fibre prestress as a novel mould-free method for producing curvatures within carbon fibre and glass fibre laminates. Tailoring the flexural rigidity along the primary orientation of the laminate is shown to result in a complex, compound curvature profile with high accuracy. An analytical model based on Euler-Bernoulli beam theory is proposed and demonstrated to correlate closely with the experiential laminates. An inverse design approach based on a Genetic Algorithm is demonstrated to design a reasonable laminate configuration to achieve the top surface of a NACA 4412 aerofoil section using the proposed eccentric fibre prestress.
Development of a simple offshore ground motion prediction equation based on S-net data and residual analysis to reveal site effects
Authors: Nakanishi Ryo , Takemura Shunsuke 
Published: December 2023

Abstract
Ground motion prediction equations (GMPEs) in offshore regions are important for evaluating the durability of subsea structures and tsunami risk associated with seafloor slope failures. Since the ground conditions differ between onshore and offshore areas, it is desirable to develop a GMPE specific to the seafloor. Previous models have some problems, such as the influence of buried observation equipment and whether physical property that substitutes for seafloor conditions can take site effects. In this study, to predict the distribution of seafloor seismic acceleration, a new GMPE was regressed on the peak ground acceleration (PGA) data of S-net using minimum necessary seismic parameters as explanatory variables. The obtained model was compared with conventional onshore and offshore GMPEs and successfully predicted PGA with smaller errors. The residuals between the observed and predicted PGA were used to examine the factors responsible for the site effect of the S-net sites. The areas overestimated by GMPE correspond to areas where semi-to-consolidated sediments are exposed and do not correlate with sediment thickness obtained from seismic reflection surveys. The new GMPE can obtain PGA within 300 km of the epicenter from the moment magnitude (Mw 5.4–7.4), focal depth, and source distance considering the marine geology.
Parietex™ Mini Male Sling for Stress Urinary Incontinence at the Time of Three Piece Penile Prosthesis: Technique and Outcomes
Authors: Razdan Shirin , Siegal Alexandra , Valenzuela Robert 
Published: December 2023

Abstract
Male stress urinary incontinence (SUI) is often comorbid with erectile dysfunction (ED) post prostatectomy. While the three piece inflatable penile prosthesis (IPP) is the gold standard surgical option for ED, there are many surgical options for male SUI as well as climacturia. We present our technique and outcomes for mini male sling (MMS) with IPP insertion for mild SUI and climacturia using a monofilament polyester mesh. A retrospective review of all IPPs performed by a single high-volume prosthetic urologist was conducted. A subset of men who underwent IPP insertion with concomitant MMS were identified and analyzed. The technique of MMS placement involves measurement of an approximately 5x3 cm two layered Parietex™ mesh (Covidien, MN); the mesh is overlayed ventrally on the bulbar urethra at the penoscrotal junction, just proximal to the corporotomy sites. The Parietex™ mesh includes a hydrophilic absorbable collagen film to minimize tissue reaction and risk of erosion. The lateral edges of the mesh are sutured to the 3 and 9 o’clock positions on the left and right corporal bodies, respectively, using a nonabsorbable, braided suture. Tightness of mesh is measured using the proximal end of a Debakey forceps, with ease of passage when the IPP is deflated, and inability to pass forceps when the IPP is inflated. A total of 63 men underwent IPP with MMS between January 2018 and October 2022. All patients had a diagnosis of concomitant ED and SUI after radical prostatectomy. Average IPP size was 21 cm with a 1 cm rear tip extender. A total of 59 men had SUI, with an average pad per day (PPD) of 1.5. Twenty-five men with SUI had comorbid climacturia, and 4 men had preoperative climacturia without SUI. Average PPD post IPP with MMS was 0.1. Of the 29 men with preoperative climacturia, only one did not have resolution of his symptoms post MMS. There was only one reported complication of acute urinary retention requiring sling removal. Two patients required subsequent AUS insertion, and two required IPP revision for malpositioned cylinders. There were no reported cases of infection or mesh erosion. The Parietex™ mesh is a safe, cost-effective, easy to use, and an effective material for mini male sling insertion at the time of IPP placement for men with ED and mild SUI or climacturia.
Thermodynamic geometric analysis of 3D charged black holes under f(R) gravity
Authors: Chen Wen-Xiang , Zheng Yao-Guang 
Published: December 2023

Abstract
This article investigates 3D charged black holes within the scope of f(R) gravity, focusing on their thermodynamic attributes. The research primarily examines minor fluctuations around these black holes' equilibrium states and delves into their modified thermodynamic entropy. Utilizing geometric thermodynamics (GTD), the study evaluates the curvature scalar's role in pinpointing phase transition points in these black holes. A key finding is that several 3D charged black holes under f(R) gravity display thermodynamic properties akin to an ideal gas when their initial curvature scalar remains constant. Conversely, with a non-constant curvature scalar and a cosmological constant term that includes a negative exponent, these black holes exhibit characteristics similar to a van der Waals gas. The article outlines general solutions for scenarios involving non-negative powers and specific solutions for cases with negative powers. Notably, under certain conditions, a phase transition resembling that of a van der Waals gas is observed, suggesting a strong correlation between the black hole's fate and the cosmological constant, extending beyond the parameters proposed by the no-hair theorem.
Integration of Field-oriented and steady-state linear Kalman filter control in PMSG-based grid-connected system for improving Voltage Control and Power Balance Operation
Authors: Parmar Devang B , Giri Ashutosh K 
Published: December 2023

Abstract
The aim of this research study is to improve the dependability and effectiveness of the wind energy supply system by specifically examining the grid-connected permanent magnet synchronous generator system (PMSG). The proposed system requires the connection of a common DC-link with two converters arranged in a back-to-back arrangement. The machine-side Field Oriented Control (FOC) utilizes the rotor position and generator speed. In this closed-loop control system, the regulation of torque is achieved indirectly by adjusting the stator current. The control scheme is formulated within the synchronous DQ frame. On the grid side control, modifications are involved for regulating the reference current generation exhausting the Steady State Linear Kalman Filter (SSLKF) control algorithm, improving power quality issues in the inverter, and regulating DC-link voltage to accomplish smooth power transfer under steady-state and dynamic conditions. The framework with closed loops equalizes power between the inverter, grid, and load. In a grid-connected system, power equilibrium is established at the point that the wind speed drops below the cut-in threshold. This system has been constructed with PMSG, a grid-connected bidirectional converter, and a nonlinear load designed in MATLAB Simulink.

Published: December 2023

Abstract
This study examines the comparative effectiveness of semaglutide intervention and metformin monotherapy in the management of type 2 diabetes. A total of 238 participants were enrolled in this randomized controlled trial, with one group receiving semaglutide in addition to standard diabetes care and the other receiving metformin alone. Various metabolic and health-related scores, including metabolic score, food score, stability score, glucose score, combined score, metabolic health score, sleep score, recovery score, heart rate variability (HRV), skin temperature, and Glucose Management Indicator (GMI), were assessed.
The results revealed that the intervention group receiving semaglutide exhibited improved metabolic health, healthier dietary habits, greater glucose stability, better glucose control, and enhanced overall health outcomes compared to the metformin monotherapy group. These findings highlight the potential benefits of GLP-1 receptor agonists like semaglutide in optimizing diabetes management. However, limitations such as study duration and sample size should be considered. Further research is warranted to validate and expand upon these results.

Abstract
This paper focuses on Coverage Path Planning (CPP) methodologies, particularlyin the context of multi-robot missions, to efficiently cover user-defined Regions ofInterest (ROIs) using UAV swarms, while emphasizing on the reduction of energyconsumption and mission duration. Optimizing the efficiency of multi-robot CPPmissions involves addressing critical factors such as path length, the number ofturns, re-visitations, and launch positions. Achieving these goals, particularly incomplex and concave ROIs with No-Go Zones, is a challenging task. This workintroduces a novel approach to address these challenges, emphasizing the selectionof launch points for UAVs. By optimizing launch points, the mission’s energy andtime efficiency are significantly enhanced, leading to more efficient coverage ofthe selected ROIs. To further support our research and foster further exploration on this topic, we provide the open-source implementation of our algorithm andour evaluation mechanisms.

Published: December 2023

Abstract
Background
Acute respiratory failure is one of the most common causes of hospitalizations in the US. By 2030, the number of Americans with dementia is expected to reach nearly 9 million and 12 million in 2040. Dementia increases the risk of respiratory illnesses, including pneumonia. This study delves into the intricate interplay between dementia and acute respiratory failure.
Methods
Our retrospective study analyzed adult patients with acute respiratory failure and secondary diagnosis of dementia using ICD-10 codes in the National Inpatient Sample (NIS) Database from 2017 to 2020. An analysis was conducted on various demographic factors such as age, race, and gender. The study's primary endpoint was mortality, with mechanical ventilation, tracheostomy, and length of stay as secondary endpoints. To account for other variables that could have affected the results, we utilized a multivariate logistic regression with p < 0.05 considered significant.
Results
The study included 1,795,630 patients admitted with ARF, 112,175 of whom had dementia. The mean age in the dementia group was 80 years, compared to 65 years in the control group. Additionally, 62% of the dementia group were females, while the control group had 55% females. 73% of both groups were Caucasian white. Comorbidities observed in the dementia group include hypertension (81% vs. 72%), diabetes mellitus (36% vs. 35%), supraventricular tachycardia (29% vs. 20%), and sepsis (6% vs. 5%) with p-value less than 0.01. Rates and odds of mortality were higher in the dementia group (15,704 (14%) vs. 151,511 (9%), p-value < 0.01, aOR 1.08, p-value < 0.01). Patients with dementia had lower rates of in-hospital mechanical ventilation, but higher adjusted odds (27% vs. 28%; p < 0.01; aOR + 1.2, p < 0.01). Patients with dementia had lower rates and adjusted odds of undergoing a tracheostomy during their stay (762 (0.7) vs. 16,834 (1), p-value < 0.01, aOR 0.91 p-value 0.33).. Patients with dementia had a longer length of stay (LOS) than those without, with a mean difference of + 0.3 days and p-value < 0.01.
Conclusions
Clinicians should be aware that dementia was found to be an independent risk factor for mortality in patients admitted with acute respiratory failure.

Abstract
Improving the transfer of foreign genes into recalcitrant cells, as in the production of transgenic animal models, is a challenge. Sperm-mediated gene transfer (SMGT) is a cost-effective and rapid method for exogenous DNA transferring into egg by sperm during fertilization. This method can be improved using chemical and natural additives. The objective of this study was to examine how sperm function, DNA uptake, embryonic development, and apoptosis rates are affected by different levels of ROS under varying oxidant and antioxidant conditions in SMGT method. Sperm isolated from mice with and without plasmid were treated with varying concentrations of H2O2 and melatonin. Under oxidation conditions, sperm performance was significantly reduced compared to the melatonin treatment. Embryos from the oxidation group with 100 µM H2O2 treatment showed higher uptake of exogenous DNA, and the proportion of GFP-positive blastocysts was significantly higher than those from higher concentrations. The data demonstrate that oxidative conditions in sperm are associated with increased absorption of exogenous DNA, potentially due to an increase in the mitochondria ability resulting from reactive oxygen species increase and sperm membrane instability. The importance of antioxidants lies in their ability to safeguard DNA against oxidative stress, enhance absorption efficacy, and bolster the stability of the sperm membrane. The study showed that antioxidants reduced the risk of negative effects on sperm quality and function.
Periarticular Blast Wounds Without Fracture: A Prospective Case Series
Authors: Covey Dana Curtis , Gentchos Christopher 
Published: December 2023

Abstract
Background
During the wars in Afghanistan and Iraq most injuries to service members involved the musculoskeletal system. These wounds often occurred around joints, and in some cases result in traumatic arthrotomy -- a diagnosis that is not always clear, especially when there is no concomitant articular fracture. The aim of the present study is to evaluate the diagnosis and treatment of peri-articular blast injuries without fracture.
Methods
The study cohort included 12 consecutive patients (12 involved extremities) who sustained extremity periarticular blast wounds without fractures. The diagnosis of penetrating articular injury was based on clinical examination, radiographic findings, or aspiration. A periarticular wound was defined as any wound, or radio-opaque blast fragment, within 5 cm of a joint. The New Injury Severity Score (NISS) was calculated for each patient. Four patients had upper, and 8 patients had lower extremity injuries. Nine of 12 patients had joint capsular penetration and underwent joint irrigation and debridement.
Results
Two patients had retained intra-articular metal fragments. One patient had soft tissue blast wounds within 5 cm of a joint but did not have joint capsule penetration. There were no significant differences (p = 0.23) between the distribution of wounds to upper versus lower extremities. However, there were a significantly greater number blast injuries attributed to Improvised Explosive Devices (IEDs) than from other blast mechanisms (p = 0.01).
Conclusion
Extremity blast injuries in the vicinity of joints involving only soft tissues present a unique challenge in surgical management. A high index of suspicion should be maintained for joint capsular penetration so that intra-articular injuries may be appropriately treated.
Resistant Pre-Exposure Prophylaxis (PrEP) Increases the Incidence of HIV, Mpox, and Sexually Transmitted Infections: Analysis of Barriers and Challenges using Bibliometric Surveillance
Authors: Adnyana I Made Dwi Mertha , Darmawan Kadek 
Published: December 2023

Abstract
This study analyzed research trends related to Pre-exposure Prophylaxis (PrEP) resistance in the increasing incidence of HIV, Mpox, and sexually transmitted infections. A total of 2,783 articles were collected from the Scopus, PubMed, and Web of Science databases; however, only 925 original articles were included for further analysis. The term "exposure prophylaxis" and its related terms were found to be the dominating term cluster, indicating that this is a trending research hotspot. The emerging terms "resistance" and "drug resistance" are associated with research related to "arvs," "cabotegravir," "doxycycline pep," "doxycycline," "doxypep," "methamphetamine," "ritonavir," "tenofovir," "tenofovir disoproxil," and "truvada." The study also identified barriers and challenges related to PrEP resistance, including stigmatization associated with PrEP use, low affordability and insurance coverage, low knowledge of the importance of PrEP, and lack of access to health services and mental health support. This study recommends comprehensive sexual health education, routine testing for at-risk individuals, and open counseling utilizing social media to provide targeted and measurable assistance.
Users’ and therapists’ perspectives on the design of a virtual reality environment to train prosthesis control: a narrative review and focus group study
Authors: Rozevink Samantha G , Murgia Alessio , Bongers Raoul M , Sluis Corry K van der 
Published: December 2023

Abstract
Introduction: Virtual Reality (VR) is becoming increasingly popular to learn a complex skill, and hence has been used to train the control of upper limb prostheses. It is however unclear what characteristics a VR environment should have in order to become a usable and effective training environment. Our aim was to develop a framework containing the most important factors to be incorporated when designing a VR environment to train prosthesis control.
Methods: A mixed method approach was used. First, a narrative review was conducted to explore factors that should be considered when designing a VR environment for prosthesis control. Second, a preliminary framework, based on these factors, was presented to prosthesis users and therapists via a questionnaire. Participants chose the most important factors to be incorporated in a VR environment. Finally, the results were discussed in focus groups.
Results: Forty-nine out of 489 articles, were included. The preliminary framework comprised 62 factors in four domains: feedback, control, exercise and environment. Five prosthesis users and eight therapists participated in three focus groups. A final framework was developed which contained 46 factors in the four domains. End-users considered all domains to be equally important, since domains and factors influence each other.
Discussion: Future research should investigate aspects of VR enjoyment, implementation of bimanual training and the development of a testing environment with peer support.
Conclusion: The developed framework can be used to guide the design of a VR environment to train prosthesis control.

Published: December 2023

Abstract

Background
Uveal melanoma is a rare type of melanoma. Most of them occur in the choroid, and a few may be found in the iris and ciliary body. The management of localized melanoma can be divided into globe-preserving therapy or enucleation. We report a case of melanoma arising from the iris and ciliary body combined with aplastic anaemia, which was successfully treated by local resection of the tumor and achieved favorable visual outcome.
Case presentation
A 31-years-old man presented with repeated episodes of Painful visual loss in his right eye for 4 years. He was diagnosed with aplastic anaemia ten years ago. Slit lamp examination showed anterior synechia, keratoleukoma and a mass in both of the anterior and posterior chamber. The IOP of right eye was elevated. Based on clinical examination: Ultrasound Biomicroscopy B-scan ultrasonography, Computerized Tomography, a presumed diagnosis of iris and ciliary body tumor and secondary glaucoma was made. The patient underwent local excision of the mass. Histopathological examination of the resected material showed a melanoma. Postoperatively, the best corrected visual acuity was improved and there was no recurrence of the tumor at the end of 7 years’ follow-up.
Conclusions A Giant iris and ciliary tumor was successfully treated by local resection, with favorable visual outcome and no recurrence for 7 years follow up. Melanoma can be differentiated from other iris and ciliary body tumors by immunohistochemical examination.
