Authors: Pérez-Salinas Cristian , de Lacalle L. N. López , Fernández-Lucio Pablo , Pereira-Neto Octavio 
Published: August 2023

AbstractThis paper describes the use of the “Dragging” (DF) cutting edge preparation process with 2 grit sizes and three mixing ratios. Both the immersion depth of the tool in the abrasive medium and the dragging duration time were manipulated. A Repeatability and Reproducibility (R&R) analysis and edge radius (ER) prediction were carried out using Machine Learning by Artificial Neural Network (ANN). The results achieved were that the influencing factors on the ER in order of importance were drag depth, drag time, mixing percentage and grain size respectively. Furthermore, the reproduction accuracy of the ER is reliable in comparison with traditional processes such as brushing and blasting and the prediction accuracy of the ER of preparation with ANN was 94% showing the effectiveness of the algorithm. Finally, it is demonstrated that DF has reliable feasibility in the application of cutting-edge preparation on carbide tools.

Published: August 2023

AbstractAdditive manufacturing parts often need post-treatment due to inherent shortcomings, such as poor surface quality or mechanical performance. Ball burnishing, a plastic deformation technique, can reduce these drawbacks. In this research, a specific tool was designed, and statistical models were used to determine optimal process parameters. Flexural and fatigue tests were conducted to assess the effects of ball burnishing on surface and dimensional quality, hardness, and mechanical behavior. The study shows that ball burnishing can benefit cast filament parts made of three materials and provides generalizations for its application. This research represents a novel contribution to using ball burnishing and highlights its advantages.

Published: August 2023

AbstractSmall-scale wind turbines can play an important role in the energy transition by providing distributed generation in urban and rural areas. They can help decrease the reliance on traditional forms of energy generation, such as fossil fuels, which can have negative environmental impacts. Thereby, this study aims to implement and complement a computational fluid dynamics (CFD) methodology for predicting the aerodynamic performance of a H-Darrieus Vertical Axis Wind Turbine (VAWT). The analysis of dimensionless numbers, such as Grid-reduced Vorticity (GRV) and Reference Courant Number (Co*), is used to indicate the suitability of spatial and temporal discretizations. Results for Power Coefficient (Cp) agreed with data from the literature and were associated with corresponding GRV and Co* values. It was also identified that incorporating the evaluation and analysis of dimensionless numbers as simulation parameters can guide methodology settings and significantly reduce simulation time compared to conventional methods such as mesh independence studies.
An Integrated Methodology for the Optimization of Process Parameters in Micromanufacturing: A Micromilling Case Study
Authors: Martínez David Serje , Cifuentes Eduardo Diez , Giraldo Michael Miranda , Bolívar Jovanny Pacheco 
Published: August 2023

AbstractMicromachining combines a series of material removal processes that give flexibility and efficiency while manufacturing microcomponents in a wide range of materials, and geometries. On the micro-scale, some challenges must be addressed due to size effects, vibrations, tool rigidity, and others. Therefore, often process parameters tend to be very conservative and may not achieve the expected performance level. This study proposes an integral methodology for optimal parameter selection, being applied in the Titanium micromilling. The results show that it is possible to optimize the process parameters with a hybrid strategy with efficient use of time and resources.

Published: August 2023

AbstractSurface roughness is an essential property in the manufacturing industry to assess the quality of its products after finishing operations. However, the evaluation of surface quality in wood products usually depends on the subjective inspection of the operators, which implies a high variability in the final quality of the pieces. This study proposes a new method to estimate roughness parameters by applying algorithms on images of wood parts processed by robotic sanding. For this purpose, this article presents a hybrid approach based on features using the co-occurrence matrix applied to greyscale images processed with five edge detection algorithms. For the evaluation of the performance of this method, the researchers correlated five features for each edge detection algorithm with standard surface roughness parameters, obtaining high correlations. The results of this study constitute a first step in implementing the proposed method in inspection systems for optical roughness measurement of wood products in automated industrial environments.

Published: August 2023

AbstractIn this work, a computer vision algorithm for the detection and recognition of 2D kinematic diagrams, both from paper schemes and digital files, was developed. Furthermore, it runs even with hand-made diagrams, which can be correctly identified. The algorithm is mainly based on the use of the free computer vision library OpenCV, being able to identify each element of the kinematic diagram, its connection with the other elements and store its pixels, which will allow in future research the implementation of motion in the sketches themselves. Allowed elements are revolute, prismatic, fixed, cylindrical and rigid joints and rigid bars. The main applications of this work are focused on the teaching world, communication of ideas in a quickly and graphical way and for fast and preliminary designs of new mechanisms as people can draw the diagram in a Tablet or paper and simulate it in real time, avoiding the necessity to learn how to operate a specialized simulation software and the time it takes to prepare the virtual model and obtain its results.
Edge Local Differential Privacy for Dynamic Graphs
Authors: Paul Sudipta , Salas Julián , Torra Vicenç 
Published: August 2023

AbstractHuge amounts of data are generated and shared in social networks and other network topologies. This raises privacy concerns when such data is not protected from leaking sensitive or personal information. Network topologies are commonly modeled through static graphs. Nevertheless, dynamic graphs better capture the temporal evolution and properties of such networks. Several differentially private mechanisms have been proposed for static graph data mining, but at the moment there are no such algorithms for dynamic data protection and mining. So, we propose two locally $$\epsilon $$
ϵ
-differentially private methods for dynamic graph protection based on edge addition and deletion through the application of the noise-graph mechanism. We apply these methods to real-life datasets and show promising results preserving graph statistics for applications in community detection in time-varying networks.The main contributions of this work are: extending the definition of local differential privacy for edges to the dynamic graph domain, and showing that the community structure of the protected graphs is well preserved for suitable privacy parameters.

Published: August 2023

AbstractBackgroundCombat‐related gunshot wounds (GSW) may differ from those found in civilian trauma centers. Missile velocity, resources, logistics, and body armor may affect injury patterns and management strategies. This study compares injury patterns, management, and outcomes in isolated abdominal GSW between military (MIL) and civilian (CIV) populations.MethodsThe Department of Defense Trauma Registry (DoDTR) and TQIP databases were queried for patients with isolated abdominal GSW from 2013 to 2016. MIL patients were propensity score matched 1:3 based on age, sex, and extraabdominal AIS. Injury patterns and in‐hospital outcomes were compared. Initial operative management strategies, including selective nonoperative management (SNOM) for isolated solid organ injuries, were also compared.ResultsOf the 6435 patients with isolated abdominal GSW, 183 (3%) MIL were identified and matched with 549 CIV patients. The MIL group had more hollow viscus injuries (84% vs. 66%) while the CIV group had more vascular injuries (10% vs. 21%) (p < .05 for both). Operative strategy differed, with more MIL patients undergoing exploratory laparotomy (95% vs. 82%) and colectomy (72% vs. 52%) (p < .05 for both). However, no difference in ostomy creation was appreciated. More SNOM for isolated solid organ injuries was performed in the CIV group (34.1% vs. 12.5%; p < 0.05). In‐hospital outcomes, including mortality, were similar between groups.ConclusionsMIL abdominal GSW lead to higher rates of hollow viscus injuries compared to CIV GSW. MIL GSW are more frequently treated with resection but with similar ostomy creation compared to civilian GSW. SNOM of solid organ injuries is infrequently performed following MIL GSW.
Validity of leg length measurement in the supine and standing position compared with pelvic survey X-ray after total hip arthroplasty

Published: August 2023

Abstract
Introduction
The correct adjustment of leg length is a major goal in the implantation of total hip replacements (THRs). Differences in leg length can lead to functional impairment and patient dissatisfaction. By determining leg length at an early stage, before the patient is discharged from hospital, compensatory measures such as the production of special insoles or orthopaedic footwear can be initiated promptly if there is a difference in leg length. Due to shortening of the period of time spent in hospital, the traditional measurement of leg length in a standing position may be increasingly subject to error. A protective posture immediately after surgery or the presence of a twisted pelvis, for example, due to scoliotic spinal misalignments, falsifies the measurement result in the standing position. Here, the measurement of leg length in the supine position may prove to be accurate immediately postoperatively, regardless of potential sources of error, and is to be compared with measurement in the standing position versus radiological measurement on the AP pelvic survey.

Material and methods
The present retrospective study included 190 patients who had undergone primary total hip arthroplasty. The leg length difference (LLD) of the patients was determined pre- and postoperatively both in the supine and standing position and compared with the postoperative radiological pelvic survey image.

Results
Postoperatively, it was shown that the mean length measured was 0.35 mm too long in the supine position and 0.68 mm too short in the standing position (p value < 0.001). Determination of the average absolute measurement error produces a deviation of 4.06 mm in the standing and 4.51 mm in the supine position (p value 0.126).

Conclusions
It is shown that the postoperative measurement of LLD in the supine and standing position is equally valid and sufficiently accurate, compared with the gold standard of measurement on a radiograph.

Published: August 2023

SummaryVibrio cholerae, an important human pathogen, is naturally occurring in specific aquatic ecosystems. With very few exceptions, only the cholera-toxigenic strains belonging to the serogroups O1 and O139 are responsible for severe cholera outbreaks with epidemic or pandemic potential. All other nontoxigenic, non-O1/non-O139V. cholerae(NTVC) strains may cause various other diseases, such as mild to severe infections of the ears, of the gastrointestinal and urinary tracts as well as wound and bloodstream infections. Older, immunocompromised people and patients with specific preconditions have an elevated risk. In recent years, worldwide reports demonstrated that NTVC infections are on the rise, caused amongst others by elevated water temperatures due to global warming.The aim of this review is to summarize the knowledge gained during the past two decades onV. choleraeinfections and its occurrence in bathing waters in Austria, with a special focus on the lake Neusiedler See. We investigated whether NTVC infections have increased and which specific environmental conditions favor the occurrence of NTVC. We present an overview of state of the art methods that are currently available for clinical and environmental diagnostics. A preliminary public health risk assessment concerning NTVC infections related to the Neusiedler See was established. In order to raise awareness of healthcare professionals for NTVC infections, typical symptoms, possible treatment options and the antibiotic resistance status of Austrian NTVC isolates are discussed.

Published: August 2023

Abstract
Objectives
This study was aimed at evaluating the clinical and radiological outcomes of novel dynamic navigation (DN)–aided endodontic microsurgery (EMS), with an analysis of potential prognostic factors.

Materials and methods
Forty-six teeth from 32 patients who received DN-aided EMS were included. Clinical and radiographic assessments were performed at least 1 year postoperatively. Two calibrated endodontists assessed radiological outcomes according to two-dimensional (2D) periapical radiography (PA) and three-dimensional (3D) cone-beam computed tomography (CBCT) imaging using Rud’s and Molven’s criteria and modified PENN 3D criteria, respectively. Fisher’s exact test was used for statistical analysis of the predisposing factors.

Results
Of the 32 patients with 46 treated teeth, 28 with 40 teeth were available for follow-up. Of the 28 patients, four (five teeth) refused to undergo CBCT and only underwent clinical and PA examinations, and the remaining 24 (35 teeth) underwent clinical, PA, and CBCT examinations. Combined clinical and radiographic data revealed a 95% (38/40) success rate in 2D healing evaluations and a 94.3% (33/35) success rate in 3D healing evaluations. No significant effect was found in sex, age, tooth type, arch type, preoperative lesion volume, preoperative maximum lesion size, presence/absence of crown and post, and the root canal filling state on the outcome of DN-aided EMS.

Conclusions
DN-aided EMS has a favorable prognosis and could be considered an effective and reliable treatment strategy. Further investigations with larger sample sizes are required to confirm these results.

Clinical relevance
DN-aided EMS could be considered an effective and reliable treatment strategy.
Do Flood and Heatwave Experiences Shape Climate Opinion? Causal Evidence from Flooding and Heatwaves in England and Wales
Authors: Lohmann Paul M. , Kontoleon Andreas 
Published: August 2023

AbstractUnderstanding how personal experience of extreme weather events raises awareness and concern about climate change has important policy implications. It has repeatedly been argued that proximising climate change through extreme weather events holds a promising strategy to increase engagement with the issue and encourage climate change action. In this paper, we exploit geo-referenced panel data on climate change attitudes as well as natural variation in flood and heatwave exposure in England and Wales to estimate the causal effect of extreme weather events on climate change attitudes and environmental behaviours using a difference-in-differences matching approach. Our findings suggest that personal experience with both flooding and heatwaves significantly increases risk perception towards climate change impacts but has no effect on climate change concern or pro-environmental behaviour, on average. Moreover, the findings indicate that the effect of flooding on risk perception is highly localised and diminishes at greater distances. For heatwaves, we find that the effect on risk perception is driven by the recent salient summer heatwaves of 2018 and 2019. Having experienced both events also significantly increases climate change concern and pro-environmental behaviour, in addition to risk perception.

Published: August 2023

AbstractMesoporous silica materials of MCM-48 and MCM-41 types were synthetized by surfactant directed methods and modified with copper by template ion-exchange (TIE) protocol and its extended version including post-treatment of modified silicas with ammonia solution. Obtained samples were characterized with respect to their textural parameters (low-temperature N2 sorption), porous structure, chemical composition, surface acidity (NH3-TPD), form and aggregation of deposited copper species (UV–vis-DRS) as well as their reducibility (H2-TPR). It was shown that application of TIE method resulted in deposition of copper into MCM-48 in more dispersed forms comparing to MCM-41. Both, in the case of MCM-41 and MCM-48, treatment of the samples with ammonia directly after copper introduction resulted in deposition mainly monomeric copper cations. The catalysts containing such dispersed copper species were more active in the low-temperature NH3-SCR process. The NO conversion above 90% with selectivity to N2 above 97% was obtained in the temperature range of 225–325 °C. CuO aggregates, deposited on mesoporous silicas, were found to be active in the side process of direct ammonia oxidation at higher temperatures.

Published: August 2023

AbstractThe present study explored the acceptability, feasibility, fidelity, and outcomes of a young adult adaptation of multidimensional family therapy (MDFT), an evidence-based family treatment originally developed for adolescents. Participants included 22 individuals between the ages of 19 to 25 who were enrolled in a criminal drug court program. MDFT was found to be feasible and was delivered with strong fidelity to young adults and their families. Participants reported high satisfaction with MDFT, and 95% completed treatment. Analyses revealed statistically significant decreases in substance use on all indicators from baseline to the 6-month follow-up. Significant improvements were also noted in vocational functioning, including a 73% increase in full-time employment from baseline to 6-month follow-up. Criminal justice outcomes included a significant decrease in legal risk, and 86% of study participants had no rearrests from baseline through the 18-month follow-up period. The article concludes with recommendations for implementing family-based interventions with young adults, as well as future research directions in this important area.

Published: August 2023

AbstractPre-operative simulated practice allows trainees to learn robotic surgery outside the operating room without risking patient safety. While simulation practice has shown efficacy, simulators are expensive and frequently inaccessible. Cruff (J Surg Educ 78(2): 379–381, 2021) described a low-cost simulation model to learn hand movements for robotic surgery. Our study evaluates whether practice with low-cost home simulation models can improve trainee performance on robotic surgery simulators. Home simulation kits were adapted from those described by Cruff (J Surg Educ 78(2): 379–381, 2021). Hand controllers were modified to mimic the master tool manipulators (MTMs) on the da Vinci Skills Simulator (dVSS). Medical students completed two da Vinci exercises: Sea Spikes 1 (SS1) and Big Dipper Needle Driving (BDND). They were subsequently assigned to either receive a home simulation kit or not. Students returned two weeks later and repeated SS1 and BDND. Overall score, economy of motion, time to completion, and penalty subtotal were collected, and analyses of covariance were performed. Semi-structured interviews assessed student perceptions of the robotic simulation experience. Thirty-three medical students entered the study. Twenty-nine completed both sessions. The difference in score improvement between the experimental and control groups was not significant. In interviews, students provided suggestions to increase fidelity and usefulness of low-cost robotic home simulation. Low-cost home simulation models did not improve student performance on dVSS after two weeks of at-home practice. Interview data highlighted areas to focus future simulation efforts. Ongoing work is necessary to develop low-cost solutions to facilitate practice for robotic surgery and foster more inclusive and accessible surgical education.

Published: August 2023

AbstractAmyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease that affects nerve cells in the brain and spinal cord, causing loss of muscle control, muscle atrophy and in later stages, death. Diagnosis has an average delay of 1 year after symptoms onset, which impairs early management. The identification of a specific disease biomarker could help decrease the diagnostic delay. MicroRNA (miRNA) expression levels have been proposed as ALS biomarkers, and altered function has been reported in ALS pathogenesis. The aim of this study was to assess the differential expression of plasma miRNAs in ALS patients and two control populations (healthy controls and ALS-mimic disorders). For that, 16 samples from each group were pooled, and then 1008 miRNAs were assessed through reverse transcription-quantitative polymerase chain reaction (RT-qPCR). From these, ten candidate miRNAs were selected and validated in 35 ALS patients, 16 ALS-mimic disorders controls and 15 healthy controls. We also assessed the same miRNAs in two different time points of disease progression. Although we were unable to determine a miRNA signature to use as disease or condition marker, we found that miR-7-2-3p, miR-26a-1-3p, miR-224-5p and miR-206 are good study candidates to understand the pathophysiology of ALS.
