Published: September 2022

Abstract
3D scanning is a crucial step to ensuring the machining quality of the workpiece and is an essential part of intelligent manufacturing. However, existing scanning systems usually have only one profiler, which must be combined with a dynamic tracking system to achieve a complete scan of a workpiece. This scanning method has low efficiency and complicated path planning for ring-shaped workpieces. Therefore, in this article, an efficient and high-accuracy 3D scanning system composed of a linear translation stage and four uniformly distributed laser profilers is built, and its extrinsic calibration method is studied. At first, based on the working parameters and spatial layout of multiple profilers, a stereoscopic calibrator composed of three non-collinear target balls (TBs) is designed. Then, a multi-profiler data fusion method is proposed, which utilizes a linear encoder to trigger the four profilers synchronously. Finally, by simultaneously using all data from the multiple profilers and the spherical constraint of each TB, all extrinsic parameters are accurately calibrated at the same time. Experimental results show that the average probing size error of the TB with a 38.1 mm diameter is stable at about 0.007 mm, and its extended uncertainty is about 0.100 mm (k = 2). In addition, standard cylinders and bend tubes are scanned. The results show that the proposed method can meet the high-accuracy calibration requirements of the tube-bending deformation detection system.

Abstract
SA 508III steel is a typical difficult-to-machine material with high strength and high-temperature mechanical properties. In the milling process, the carbide tool is seriously damaged and their service life is short under the thermal-mechanical load of low cycle and high impact. In this paper, firstly, the finite element simulation of milling SA 508III steel is carried out to study the characteristics of thermal-mechanical load and tool wear during milling. Secondly, the wear experiment of cemented carbide tools is carried out. The morphology changes of the rake face and flank face of cemented carbide tools are observed and analyzed. The nature of tool wear and damage is discussed. Finally, the rule of crack development from microscopic defects to macroscopic cracks until tool fracture is described, and the tool failure mechanism is explored. The research results can provide theoretical basis and technical support for the optimal design of cutting tools of high-efficiency milling SA 508III steel and the improvement of cutting performance and service life of tools.

Published: September 2022

AbstractThe derived materials obtained from the sol-gel process have been used in various technological applications, such as solar cells, intelligent coatings, catalysis, and, more recently, the fabrication of bioreceptors. The objective of this study was to develop a bioreceptor consisting of a titania-based nanostructure, which was synthesized using the sol-gel method. This nanostructure was immersed in a solution containing laccase and Nafion and integrated into a graphite-based electrode (TiO2/NAF/LAC). This device is called a bioreceptor and is used to detect gallic acid. The nanostructure was characterized by x-ray diffraction, Raman spectroscopy, and scanning electron microscopy (SEM). Particle size was measured using a nanosizer. Cyclic voltammetry (CV) tests were performed on a bioreceptor. In this study, the predominant phase of TiO2was anatase, and the obtained nanoparticles had an average size of 66 nm. The CV tests of the bioreceptor showed an oxidation response that increased as the concentration of gallic acid in the solution increased, with a detection limit of 0.125μM, as well as a wide linear range that varied from 0.125 to 175μM and a factor correlation of 0.9968. As a result, it was possible to develop a bioreceptor capable of immobilizing laccase to detect gallic acid.

Abstract
Interfaces between complex oxides host a plethora of functional properties including enhanced ionic conductivity, gate-tunable superconductivity and exotic magnetic states. The enhanced electronic, ionic and magnetic properties along the oxide interfaces are generally exploited in functional devices by spatial confinement of ions and electrons. Different patterning methods have been used to spatially control the conductivity at the interface, but a key limitation is the multiple steps needed to fabricate functional devices. In this investigation, inkjet printing of thermally stable oxides is introduced as an alternative pathway for spatially controlling the interface conductivity. We inkjet print yttrium-stabilized zirconia and TiO2 with various shapes and use these as physical masks to confine the electronic conductivity in SrTiO3-based heterostructures. By performing in-situ transport measurements of the electrical conductivity as LaAlO3 and γ-Al2O3 are deposited on SrTiO3, we witness the birth of the interface conductivity and find a consistent transient behavior as conductivity emerges in patterned and non-patterned heterostructures. We find that conductivity appears after the first laser pulse in the pulsed laser deposition corresponding to the film covering only a few percent of the substrate. We attribute the emergence of conductivity to oxygen vacancies formed by a combination of plasma bombardment and oxygen transfer across the interface during growth. In this vein, inkjet patterned hard masks protects the SrTiO3 substrate, effectively confining the conductivity. The study paves a scalable way for realizing energy devices with spatially controlled electronic and ionic interface conductivity.
Implementation of a multidisciplinary inpatient opioid overdose education and naloxone distribution program at a large academic medical center
Authors: Nguyen Tu Tran , Applewhite Dinah , Cheung Fiona , Jacob Susan , Mitchell Elisabeth 
Published: September 2022

Abstract

Purpose
Opioid overdose–related deaths continue to rise. Despite public health efforts, there is still variability in obtainment of naloxone, a lifesaving antidote. We share our experience in the implementation of a novel opioid overdose education and naloxone distribution (OEND) program at a large academic medical center.

Methods
Collaborative efforts made by pharmacists, pharmacy students, physicians, nurses, and recovery coaches were employed in the design of the program. The service was available Monday through Friday, 9 am to 6 pm, and primarily carried out by pharmacy students on a rotating basis. Services offered included bedside delivery of naloxone and education prior to the day of discharge. In preparation for their role, the pharmacy students were required to complete a series of trainings and competency assessments.

Results
A total of 40 patients were included in the program evaluation. Of the completed consults 96.7% (n = 30) of patients received both counseling and naloxone delivery. Eighty percent of patients had a history of nonfatal opioid overdose, but only 37.5% had naloxone listed as a home medication. OEND services were provided to 66% of individuals with patient-directed discharges.

Conclusion
Implementation of an inpatient OEND program by mobilizing trained student pharmacists is feasible and expands naloxone access to patients during transitions of care. A similar model could be considered in the future for the delivery of harm reduction supplies to this patient population.
Rectus Plication Does Not Increase Risk of Thromboembolic Events Following Abdominal Body Contouring: A Matched Case-Control Analysis
Authors: Wang Fei , Chemakin Katherine , Shamamian Peter , Punn Isha , Campbell Tessa , Ricci Joseph A 
Published: September 2022

Abstract

Background
Rectus abdominis plication increases intra-abdominal pressure and lower-extremity venous stasis, which may increase the incidence of venous thromboembolism (VTE) events.

Objectives
The aim of this study was to investigate the potential association between VTE and rectus abdominis muscle plication during surgery.

Methods
A retrospective review of all patients who underwent abdominal body contouring at the authors’ institution between 2010 and 2020 was completed. Cases were those with postoperative VTEs and were matched to controls (1:4) via potential confounders. Variables collected include demographic data, operative details, comorbidities, and postoperative complications. Statistical analysis was performed with parametric, nonparametric, and multivariable regression modeling.

Results
Overall, 1198 patients were included; 19 (1.59%) experienced a postoperative VTE and were matched to 76 controls. The overall cohort was 92.7% female with an average age of 44 years, an average Charlson Comorbidity Index of 1 point, and an average BMI of 30.1 kg/m2. History of cerebrovascular events (14.5% vs 36.8%, P = 0.026) differed significantly between cohorts, but no significant associations were noted in all other baseline demographics. Additionally, VTE cases were more likely to have received intraoperative blood transfusions (odds ratio = 8.4, P = 0.04). Bivariate analysis demonstrated cases were significantly more likely to experience concurrent complications, including delayed wound healing (0% vs 5.3%, P = 0.044), seroma formation (5.3% vs 21.1%, P = 0.027), and fat necrosis (0% vs 5.3%, P = 0.044). However, these findings were not significant in a multivariable regression model. Plication was not associated with VTE outcomes.

Conclusions
Rectus plication does not increase the risk of VTE. However, the odds of VTE are significantly increased in patients who received intraoperative blood products compared with those who did not.

US FDA Patient Decision Checklist for Breast Implants: Results of a Survey to Members of The Aesthetic Society, April 2022
Authors: Karp Nolan , McGuire Patricia , Adams William P , Jewell Mark L 
Published: September 2022

Abstract
The US Food and Drug Administration (FDA), in response to concerns that patients undergoing breast implant surgery were not adequately informed about the risks of receiving an implanted medical device, mandated a Patient Decision Checklist (PDC) in October 2021. Breast implant manufactures communicated with plastic surgeons in 2022 regarding the use of the PDC as a condition for the sale of breast implants. Plastic surgeons voiced concerns over the accuracy of the content in the PDC and its confusing statements about the risk of adverse events associated with breast surgery. In April 2022, The Aesthetic Society developed a survey that was sent to its members regarding their experiences with the PDC. This was a 5-question survey, with 1 additional place for comments. The purpose of this survey was to develop data based on the 6-month experience of plastic surgeons with the PDC. A total of 206 Aesthetic Society members (9%) participated in the survey (1849 total active members in the United States). Patients deserve appropriate information prior to breast implant surgery to make an informed decision after reviewing the potential risks and benefits. The authors believe that there is still more work to be done to create an ideal PDC that is fair and balanced, scientifically describes risk incidence in a way that patients understand, and can be updated.
The Influence of Personality on Health Complaints and Quality of Life in Women With Breast Implants
Authors: Berben Juliënne A , Miseré Renée M L , Schop Sander J , van der Hulst René R W J 
Published: September 2022

Abstract

Background
A causal relation between systemic symptoms and breast implants has not been established. Psychological factors, such as personality and psychological distress, are strongly associated with the development of medically unexplained symptoms. It can be hypothesized that psychological factors may be related to the development of breast implant illness (BII).

Objectives
This study was conducted to evaluate the correlation between self-reported health complaints, health- and breast-related quality of life (QoL), and personality, in women with cosmetic breast implants.

Methods
Women who attended the plastic surgery outpatient clinic of Maastricht University Medical Center between October 2020 and October 2021 for reasons related to their implants and women recruited for a BII study at the Center during this period were invited to participate in this study. Only women who underwent cosmetic breast augmentation were eligible. Participants completed a physical complaints score form and the BREAST-Q, SF-36, and EPQ-RSS questionnaires via an online survey.

Results
In total, 201 women completed the questionnaires. Extroversion and social desirability were predominant personality traits in women with breast implants, followed by neuroticism. Relatively high levels of neuroticism were found compared with normative data. Neuroticism correlated significantly with health status and breast-related QoL. Physical and mental health–related QoL had the strongest correlations with neuroticism (β = −3.94, β = −4.86, P &lt; 0.001).

Conclusions
Personality can play a role in the development of complaints. High levels of neuroticism are seen in cosmetic surgery patients and are negatively correlated with subjective health and patient-reported outcomes in women with breast implants. Therefore, neuroticism may be a factor in the development of BII.

Covid-induced school closures in the United States and Germany: long-term distributional effects
Authors: Fuchs-Schündeln Nicola 
Published: September 2022

Abstract
Almost all countries worldwide closed schools at the outbreak of the Covid-19 crisis. I document that schooling time dropped on average by −55% in the United States and −45% in Germany from the onset of the crisis to the summer of 2021. In the United States, schools were closed longer in richer than in poorer areas, while in Germany the regional variation is much smaller. However, Germany exhibited substantial variation by grade level, with a strong U-shaped pattern that implies that children attending middle school faced the longest closures. A structural model of human capital accumulation predicts that the US school closures on average lead to a reduction of life-time earnings of –1.8% for the affected children. While the overall losses are likely somewhat smaller in Germany, the socio-economic gradient in the losses could be larger than in the United States, leading to increased inequality and decreased intergenerational mobility.
More than just hitchhikers: a survey of bacterial communities associated with diatoms originating from sea turtles

Published: September 2022

Abstract
Diatoms and bacteria are known for being the first colonizers of submerged surfaces including the skin of marine reptiles. Sea turtle carapace and skin harbor diverse prokaryotic and eukaryotic microbes, including several epizoic diatoms. However, the importance of diatom-bacteria associations is hardly investigated in biofilms associated with animal hosts. This study provides an inventory of diatoms, bacteria and diatom-associated bacteria originating from loggerhead sea turtles using both metabarcoding and culturing approaches. Amplicon sequencing of the carapace and skin samples chloroplast gene rbcL and 16S rRNA gene detected, in total, 634 diatom amplicon sequence variants (ASVs) and 3661 bacterial ASVs, indicating high diversity. Cultures of putative epizoic and non-epizoic diatoms contained 458 bacterial ASVs and their bacterial assemblages reflected those of their host. Diatom strains allowed for enrichment and isolation of bacterial families rarely observed on turtles, such as Marinobacteraceae, Alteromonadaceae and Alcanivoracaceae. When accounting for phylogenetic relationships between bacterial ASVs, we observed that related diatom genera might retain similar microbial taxa in culture, regardless of the turtle's skin or carapace source. These data provide deeper insights into the sea turtle-associated microbial communities, and reveal the potential of epizoic biofilms as a source of novel microbes and possibly important diatom-bacteria associations.
Stochastic variation in gut bacterial community affects reproductive rates in the water flea Daphnia magna
Authors: Obrestad Kathrine , Einum Sigurd , Vadstein Olav 
Published: September 2022

Abstract
It is well-documented that perturbation of the gut bacterial community can influence the reproductive rates of the host. Less is known about how natural ecological processes can change the bacterial composition in the gut and how such changes influence the reproductive rate of the host. Here, we provide novel experimental insights into such processes using the clonally reproducing water flea, Daphnia magna. A total of 20 replicate cultures were reared for 5 weeks (Phase 1) to allow for divergence of bacterial communities through stochastic processes (i.e. drift, founder effects, and/or colonization). Duplicate cultures created from each of these were reared for 21 days (Phase 2) while recording reproductive rates. There was a significant repeatability in reproductive rates between these duplicates, suggesting that divergence of the bacterial communities during Phase 1 translated into reproductive rate effects during Phase 2. This was further supported by significant differences in the relative abundance of gut bacteria (investigated by amplicon sequencing of a part of the 16S rRNA gene) between cultures with high and low reproductive rate in Phase 2. These results are consistent with the hypothesis that stochastic processes can cause natural variation in the bacterial composition in the gut, which in turn affect host reproductive rates.

Published: September 2022

AbstractThis study analyzes the Amazon rainforest in the Brazilian state of Rondônia from the perspective of the forest regeneration observed from 2008 to 2018. The research examines the regeneration’s contribution to the landscape’s morphological spatial pattern within the state’s geographical limits, conservation units, indigenous lands, and the unprotected region. It assesses how the increase of forest regeneration areas influences morphological spatial patterns and evaluates whether the landscape in Rondônia has benefited from these new areas. The GuidosToolbox software was used to extract the morphological spatial pattern and the indices of morphological spatial patterns of forest habitats. The findings showed that Rondônia developed forest regeneration areas for 10 years, but these areas contributed little to improving the landscape morphological spatial patterns. The increase in regeneration areas contributed adequately only in the unprotected region. Therefore, the forest regeneration was not enough to compensate for the observed deforestation. Thus, conservation actions must be complemented with restoration activities focused on reconnecting patches and increasing the size of forest habitat through projects to encourage environmental regularization of exploited areas.
Assessing the impact of Covid-19 on teaching and research: A Ghanaian perspective
Authors: Amarh Gertrude Amorkor 
Published: September 2022

Abstract
The Covid-19 pandemic in diverse ways affected the traditional modes of instruction and learning at all levels of education. Prominent among the innovations necessitated by the pandemic was the increased use of virtual methods of teaching and learning. For many learners and instructors in parts of the world, however, expensive internet data costs, lack of digital learning tools, and similar other challenges meant that the benefits of virtual teaching and learning could not be fully reaped. This article recounts my experiences of the pandemic as a Ghanaian early career researcher. It shares the experiences of law students in my University, obtained through administered questionnaires. The article also analyses how these experiences unearthed deep socio-economic inequalities among learners and lecturers alike, and how these inequalities impacted effective teaching and learning during the pandemic. Although these disparities had long existed, the conditions created by the pandemic only made them more glaring. While analyzing the institutional support received from my University, the article makes a case for the active involvement of all stakeholders in bridging the divide.
Achieving Justice for Child Survivors of Conflict-related Sexual Violence in the Democratic Republic of the Congo in Light of the Kavumu Case
Authors: Mbokani Jacques B 
Published: September 2022

Abstract
In this article, the author questions some assertions on issues of international and Congolese criminal law made in the context of an article published in a Special Issue of the Journal on ‘Justice and Accountability for Sexual Violence in Conflict: Progress and Challenges in National Efforts to Address Impunity’. While he credits the article with helping to bring to the attention of a wider audience the atrocities experienced by the victims of the Kavumu case — and thus contributing to the overall justice-effort on their behalf — he notes a few areas of legal concern, including: (i) the impact of Article 27(2) ICC Statute on parliamentary immunities in prosecuting crimes under the Rome Statute before national courts; (ii) the determination of liability of the accused when military judges have failed to identify direct perpetrators of crimes or the group to which they belong; and (iii) the relationship between the forms of criminal responsibility of individuals that make up the leadership of an organization and the policy element of crimes against humanity attributed to that organization. In sum, the article seeks to investigate to what extent the judicial reasoning in this case may have contributed to clarifying the provisions of the ICC Statute as applied by military judges in Congolese courts.
