Published: December 2021

The dependability of power electronics systems, such as three-phase inverters, is critical in a variety of applications. Different types of failures that occur in an inverter circuit might affect system operation and raise the entire cost of the manufacturing process. As a result, detecting and identifying inverter problems for such devices is critical in industry. This study presents the short-time Fourier transform (STFT) for fault classification and identification in three-phase type, voltage source inverter (VSI) switches. TFR represents the signal analysis of STFT, which includes total harmonic distortion, instantaneous RMS current, RMS fundamental current, total non harmonic distortion, total waveform distortion and average current. The features of the faults are used with a rule-based classifier based on the signal parameters to categorise and detect the switch faults. The suggested method's performance is evaluated using 60 signals containing short and open circuit faults with varying characteristics for each switch in VSI. The classification results demonstrate the proposed technique is good to be implemented for VSI switches faults classification, with an accuracy classification rate of 98.3 percent.

Authors: Kumar Kanike Vinod , Kumar R. Saravana
Published: December 2021

Reduction of switch count in symmetrical and asymmetrical reduced switch multilevel inverter designs has been proposed regularly with operation of conventional carrier-based pulse width modulation technique. In this study, a novel structure of symmetrical Hexa shaped model reduced switch seven level output inverter is proposed without any auxiliary switch and H-bridge. Proposed structure offers a smaller number of switch count and voltage sources which results in the cost and complexity reduction of its implementation. To operate the switching sequence of inverter from carrier based APOD, POD and PD methods, suitable logical expression to be realize which gained more prominence. Active utilization of two voltage sources in each mode of operation results in significant reduction of voltage stress across each switch is achieved. A comparative study of proposed MLI with various reduced switch MLIs has been presented. Initially, simulation model implementation has been carried out with MATLAB/Simulink and observed the performance parameters and THD. Simulation results are carried for the comparison of the results obtained in the real time work performed on OPAL-RT 5700 simulator.

Authors: Bin Mohd Noh Mohamad Affan , Bin Sahid Mohd Rodhi , Thiruchelvam Vinesh
Published: December 2021

This paper proposes an isolated full bridgeless single stage alternating current-direct current (AC-DC) converter. The proposed converter integrates the operation of a pure bridgeless power factor correction with input boost inductor cascaded with center-tap transformer and half bridge circuit. In addition, the bidirectional switch can be driven with single control signal which further simplifies the controller circuit. It is also proved that this converter reduces the total number of components compared to some conventional circuit and semi-bridgeless circuit topologies. The circuit operation of the proposed circuit is then confirmed with the small signal model, large signal model, circuit simulation and then verified experimentally. It is designed and tested at 115 Vac, 50 Hz of input supply, and 20 Vdc output voltage with maximum output power of 100 W. In addition, the crossover distortion at the input current is minimize at high input line frequency.

Published: December 2021

A small-signal analysis of a single-stage bridgeless boost half-bridge alternating current/direct current (AC/DC) Converter with bidirectional switches is performed using circuit averaging method. The comprehensive approach to develop the small signal model from the steady state analysis is discussed. The small-signal model is then simulated with MATLAB Simulink. The small-signal model is verified through the comparison of the bode-plot obtained from MATLAB Simulink and the simulated large signal model in piecewise linear electrical circuit simulation (PLECS). The mathematical model obtain from the small-signal analysis is then used to determine the proportional gain K_p and integral gain K_i. In addition, the switch large-signal model is developed by considering the current and voltage waveforms during load transients and steady-state conditions.
Buddhist Homiletics on Grief
Authors: Szántó Péter-Dániel
Published: December 2021

The study first introduces a hitherto completely unstudied anonymous work, for which I reconstruct the title *Saddharmaparikathā. This substantial text is a Buddhist homiletician’s guidebook with sample sermons in Sanskrit on a rich variety of topics. I argue that it dates from the 5th century and that it was possibly authored in a Saṃmatīya environment. I first discuss the unique manuscript transmitting the text, the structure and contents of the work, what information it can provide for the tradition of preaching and its importance for Buddhist studies. In the second half, I provide a sample chapter ‘On Grief’ with an annotated translation.

Intentional self-harm in culturally and linguistically diverse communities: A study of hospital admissions in Victoria, Australia
Authors: Pham Thi Thu Le , O’Brien Kerry S , Berecki-Gisolf Janneke , Liu Sara , Gibson Katharine , Clapperton Angela
Published: December 2021

Purpose:

To examine the rates and profiles of intentional self-harm hospital admissions among people from culturally and linguistically diverse and non-culturally and linguistically diverse backgrounds.

Methods:

A retrospective analysis of 29,213 hospital admissions for self-harm among people aged 15 years or older in Victoria, Australia, was conducted using data from the Victorian Admitted Episodes Dataset between 2014/2015 and 2018/2019. The Victorian Admitted Episodes Dataset records all hospital admissions in public and private hospitals in Victoria (population 6.5 million). Population-based incidence of self-harm, logistic regression and percentages (95% confidence intervals) were calculated to compare between culturally and linguistically diverse groups by birthplaces and the non-culturally and linguistically diverse groups of self-harm admissions.

Results:

When grouped together culturally and linguistically diverse individuals had lower rates of (hospital-treated) self-harm compared with the non-culturally and linguistically diverse individuals. However, some culturally and linguistically diverse groups such as those originating from Sudan and Iran had higher rates than non-culturally and linguistically diverse groups. Among self-harm hospitalised patients, those in the culturally and linguistically diverse group (vs non-culturally and linguistically diverse group) were more likely to be older, Metropolitan Victorian residents, from the lowest socioeconomic status, and being ever or currently married. Self-harm admissions by persons born in Southern and Eastern Europe were the oldest of all groups; in all other groups number of admissions tended to decrease as age increased whereas in this group the number of admissions increased as age increased.

Conclusion:

There was considerable heterogeneity in rates of hospital-treated self-harm in culturally and linguistically diverse communities, with some countries of origin (e.g. Sudan, Iran) having significantly higher rates. Some of this variation may be due to factors relating to the mode of entry into Australia (refugee vs planned migration), and future research needs to examine this possibility and others, to better plan for support needs in the culturally and linguistically diverse communities most affected by self-harm. Combining all culturally and linguistically diverse people into one group may obscure important differences in self-harm. Different self-harm prevention strategies are likely to be needed for different culturally and linguistically diverse populations.
Disinformation and gendered boundarymaking: Nordic media audiences making sense of “Swedish decline”
Authors: Edenborg Emil
Published: December 2021

This article examines how Russian geostrategic communication is entangled in global gender politics. The aim is to understand the resonance of disinformation in relation to culturalized, ethnicized and racialized narratives of gender, or “gendered boundarymaking.” The analysis is based on focus group discussions with Swedish, Danish, and Norwegian individuals, asked to share their impressions of news articles from the Russian media agency Sputnik, which all depicted Sweden as a warning example of multiculturalism and feminism gone “too far.” In the discussions, participants opposed a gender equal “self” to a patriarchal immigrant “other,” narrated Sweden as a country exceptionally concerned with gender, and tapped into competing temporalities of progress and decline. The article contributes to research on geostrategic communication by showing how disinformation efforts draw upon gendered national identities and debates about gender and immigration. More importantly, the article demonstrates that such gendered boundarymaking shapes audiences’ interpretations in crucial ways. Rather than viewing disinformation only from a state-centered lens of national security, in isolation from racism, Islamophobia, anti-feminism, and queerphobia within Western societies, research should acknowledge the interconnections between geostrategic communication and everyday boundarymaking. This will be pivotal to developing counterstrategies to disinformation, whether Russian or homegrown.
How to Measure Propensity to Take Risks in the Italian Context: The Italian Validation of the Risk Propensity Scale
Authors: Marton Giulia , Monzani Dario , Vergani Laura , Pizzoli Silvia Francesca Maria , Pravettoni Gabriella
Published: December 2021

Risk propensity is a multifaced construct that influences many aspects of life, such as decision making. In the present study, the psychometric characteristics of the Risk Propensity Scale (RPS) have been explored for the first time in an Italian sample. The RPS is a 7 item self-report questionnaire measuring people’s tendency to take risks. The English RPS has been translated following the forward–backwards translation method, and it was filled out by 199 participants. Since its dimensionality has never been explored before, its factor structure has been analysed with exploratory factor analysis that confirmed the one-factor structure of the questionnaire and the retention of all the items. The Italian version of the RPS has high internal consistency (Cronbach alphas .78), and almost all the items were positively and significantly correlated. The convergent and discriminant validity, analysed by considering the associations with decision-making styles and an implicit measure of risk propensity, were satisfactory. Overall, the Italian version of the RPS is a valid and quick questionnaire useful to measure propensity to take risks in the Italian context.
Assessment of Attachment Representations in Basque Adolescents and their Relationship with Internalizing and Externalizing Problems

Published: December 2021

Research has shown a relationship between attachment style and psychosocial adjustment in adolescents. Whereas secure attachment is related to fewer internalizing and externalizing symptoms, the opposite is the case for the various insecure attachment styles. The aim of the two studies reported in this paper was to adapt and validate the CaMir-R (a self-report measure of attachment that has shown adequate psychometric properties) for use among Basque adolescents, and to analyse the relationship between attachment and internalizing and externalizing symptoms. In Study 1, the instrument was adapted using the back translation method and applied to a sample of 203 adolescents and young adults. Confirmatory factor analysis supported the theoretical dimensions of the scale, and its psychometric properties were found to be adequate. In Study 2 we obtained additional validity evidence by applying, in a sample of 786 adolescents and young adults, the attachment representations section of the CaMir-R alongside other measures of attachment and clinical symptoms. The results once again supported the dimensional structure of the instrument, and evidence of convergent validity was obtained based on correlations between CaMir-R scores and scores on the Inventory of Parent and Peer Attachment (IPPA). In addition, scores on the five dimensions of attachment representations (Security, Family concerns, Parental interference, Self-sufficiency and resentment of parents and Childhood trauma) were correlated with scores on other measures of internalizing and externalizing symptoms. Based on these results, we conclude that the Basque version of the CaMir-R is a valid instrument for assessing the quality of attachment representations among adolescents, and also that internalizing and externalizing problems are related to attachment style. We discuss the importance of attachment in relation to behaviour problems and clinical symptoms.
Estimating the true arrival, balking, and reneging processes from censored transactional data: a simulation-based approach
Authors: Negahban Ashkan
Published: December 2021

The transactional data typically collected/available on queueing systems are often subject to censoring as unsuccessful arrivals due to balking and/or unserved entities due to reneging are not recorded. In fact, in many situations, the true arrival, balking, and reneging events are unobservable, making it virtually impossible to collect data on these stochastic processes—information that is crucial for capacity planning and process improvement decisions. The objective of this paper is to estimate the true (latent) external arrival, balking, and reneging processes in queueing systems from such censored transactional data. The estimation problem is formulated as an optimization model and an iterative simulation-based inference approach is proposed to find appropriate input models for these stochastic processes. The proposed method is applicable in any complex queueing situation as long as it can be simulated. The problem is investigated under both known and unknown reneging distribution. Through extensive simulation experiments, general guidelines are provided for specifying the parameters of the proposed approach, namely, sample size and number of replications. The proposed approach is also validated through a real-world application in a call center, where it successfully estimates the underlying arrival, balking, and reneging distributions. Finally, to enable reproducibility and technology transfer, a working example, including all codes and sample data, are made available in an open online data repository associated with this paper.
Possible Citizens: Migration Enforcement as the Performance of Citizenship in the United Arab Emirates
Authors: Lori Noora
Published: December 2021

While most boundary-making studies examine native-born citizens’ opposition to immigration, this article explains why immigrants develop anti-immigrant attitudes. Under what conditions do previous generations of immigrants develop solidarity with newcomers? When might immigrants, instead, police national boundaries and oppose further immigration or naturalization? I argue that under uncertain citizenship status, long-term immigrants are unlikely to develop solidarity with newcomers, despite common experience with exclusionary citizenship policies. Drawing on interviews with naturalization applicants in the United Arab Emirates, this article analyses how policies that unevenly distribute rights and protections to non-citizens structure relationships between immigrant groups. Moving beyond citizen/non-citizen binaries, it calls attention to hierarchies among non-citizens, examining how long-term immigrants with partial and conditional rights police national boundaries to navigate exclusionary policies. When states restrict citizenship, making it a scarce good, immigrants may respond to uncertainty by competing and, thus, limiting access to that good for newcomers. When naturalization is arduous, applicants face pressures to continually perform citizenship to prove that they deserve inclusion. Naturalization applicants lacked citizenship, but they immigrated to the UAE before the establishment of its guest-worker program and claimed Emirati identity by differentiating themselves from “migrant workers.” I show how migration enforcement and boundary-policing factored into their perceptions and performances of what it meant to be a “good” Emirati citizen. Ethnic hierarchies and the timing of migration created distinctions between immigrants eligible for naturalization and those who were not. The mere possibility of inclusion in the citizenry may generate hierarchies between immigrants, precluding solidarity, and encouraging boundary-policing.
Transgressing to teach: Theorising race and security through struggle
Authors: Rossdale Chris
Published: December 2021

Recent interventions in critical security studies have argued that the field has struggled to account for the racialised/racist foundations of security politics. This article engages with the US Black Panther Party (BPP), arguing that the Party did important work to show how security politics is dependent on racial violence. The idea that we can theorise global politics through struggle (`struggle as method’) is becoming popular within disciplinary International Relations (IR), but has longer lineages in Black radical thought. The BPP were important advocates of struggle as method, with tactics and strategies intentionally designed with a pedagogical purpose; through Panther actions (including community self-defence and survival programmes), and the state’s response to these, the mechanisms of capitalist white supremacy were laid bare. The article therefore acknowledges BPP action as a series of theoretical interventions, which demonstrated how the terms of US/white security are rooted in and dependent on anti-Blackness. It also shows how Panther tactics prefigured alternative, radical, anti-statist approaches to security, these conceptualised as `survival pending revolution’. The article closes by arguing that scholarship on critical security studies - especially as related to the racialised politics of security - should do more to work with and acknowledge its indebtedness to struggle as method.

Published: December 2021

Objectives

To evaluate 20 days and 3 months follow-up effectiveness of cardiac rehabilitation (CR) enhanced by resistance/balance training and telephone-support program compared to usual CR care in improving quality of life, clinical course and physical activity behavior.

Design

Single-centre randomized controlled trial.

Setting

Inpatient CR clinic

Subjects

116 (76.1 ± 6.7 years, 50% male) patients 14.5 ± 5.9 days after valve surgery/intervention were randomized to intervention group (IG, n = 60) or control group (CG, n = 56).

Intervention

Additional resistance/balance training (3 days/week) during phase-II CR and telephone-support program during 3-month follow-up. CG patients were provided with usual CR care.

Main measures

Short Form 36 Health Survey scales, European Quality of Life 5 Dimensions 3 Level Version QoL index, visual analog scale, clinical course, and physical activity behavior assessed with standardized questionnaires.

Results

IG reported statistically significant higher mental component score (48.5 ± 6.91 vs. 40.3 ± 11.21 at the baseline, 50.8 ± 9.76 vs. 42.6 ± 9.82 after 20 days, 49.4 ± 8.45 vs. 40.5 ± 8.9 after 12 weeks follow up), general health (48.6 ± 3.17 vs. 45.0 ± 2.95 at the baseline, 53.6 ± 3.02 vs. 43.8 ± 2.55 after 20 days, 53.2 ± 3.11 vs. 44.2 ± 3.07 after 12 weeks) and role limitations due to emotional problems (48.5 ± 15.2 vs. 27.7 ± 11.5 at the baseline, 72.7 ± 12.6 vs. 30.5 ± 11.2 after 20 days, 66.6 ± 14.2 vs. 36.1 ± 11.2 after 12 weeks) in all three assessments ( p < 0.05). CG patients had more documented hospital admissions (4 (8%) vs 10 (25%), p = 0.027), atrial fibrillation paroxysms (3 (6.0%) vs. 10 (35.0%), p = 0.011) and blood pressure swings (13 (26%) vs. 20 (50%), p = 0.019). IG patients chose more different physical activities (1.7 ± 0.7 vs. 1.25 ± 0.63, p = 0.002), spent more time being physical active every day (195.6 ± 78.6 vs. 157.29 ± 78.8, p = 0.002)

Conclusions

The addition of resistance/balance exercises and telephone-support program 12 weeks after to the CR could linked to higher physical activity levels and fewer clinical complications but did not lead to a significant improvement in quality of life.
How is Online Disinhibition Related to Adolescents’ Cyberbullying Perpetration? Empathy and Gender as Moderators
Authors: Wang Xingchao , Qiao Yuran , Li Wenqing , Dong Wanghao
Published: December 2021

The present study examined the relationship between online disinhibition and adolescents’ cyberbullying perpetration and investigated whether empathy and gender would moderate this relationship. A total of 2407 Chinese adolescents aged 11–16 years completed the questionnaires to measure their online disinhibition, empathy, and cyberbullying perpetration. Results indicated that high levels of online disinhibition were associated with high levels of cyberbullying perpetration, even after controlling for key covariates related to cyberbullying perpetration. Empathy significantly moderated the relationship between online disinhibition and cyberbullying perpetration. Specifically, this relationship was not significant at high levels of empathy. Moreover, the impact of empathy was moderated by gender. For male adolescents, online disinhibition was significantly associated with cyberbullying perpetration only when their empathy was low. For female adolescents, the relationship between online disinhibition and cyberbullying perpetration became nonsignificant, regardless of whether they had a low or high level of empathy.
Who Manages the Money at Home? Multilevel Analysis of Couples’ Money Management Across 34 Countries
Authors: Çineli Beyda
Published: December 2021

Women’s and men’s predominant social practices in managing employment and unpaid work are influenced by both family policies and society’s predominant cultural family models. Comparative approaches integrating macro-level and micro-level variables are increasingly used to study gendered dynamics in intimate relationships. Yet similar comparative approaches to the study of money management in intimate relationships are lacking. Using data from 34 countries surveyed in International Social Survey Programme 2012 data ( N = 13,645), I explore how variation in institutional and cultural factors concerning gender expectations shapes money management decisions in intimate relationships. The results highlight the importance of contextual gender-egalitarian beliefs and institutional practices to the likelihood of using joint and individualized systems of money management over the traditional system. While macro-level gender ideology was associated with both joint and individualized system (vs. traditional), the institutional practices were found to have a stronger relationship with couples’ individualized money management.
CFRP composite drilling through electrical discharge machining using aluminum as fixture plate
Authors: Pattanayak Suvranshu , Sahoo Ananda Kumar , Sahoo Susanta Kumar
Published: December 2021

Recent developments in manufacturing require holes on composite materials, especially on the carbon fiber reinforced polymer (CFRP) with smooth hole periphery, low delamination, burr formation, taper, better circularity, and a high processing speed. Its non-conductive surface (epoxy layering) limits its machining through electrical discharge machining (EDM). To overcome this limitation, an aluminum fixture has been designed to guide the copper electrode of EDM for producing holes on a CFRP sheet of 1 mm thickness at low machining complexity, cost, time, delamination, burr in hole periphery and without affecting the material’s surface quality and performance. Even components with high geometrical complexity can also be drilled through this approach. Here, a multi-quality analysis called grey relational analysis is developed for examining the hole quality attributes, considering peak current, pulse on and off time, and flushing pressure as input parameters. This approach points out the optimum factor level setting and critical parameters (pulse-on time and peak current) that regulate the hole attributes (entrance and exit diameter, circularity, taper, material removal, and tool wear rate). An artificial neural network model has been designed and trained through experimental data sets. This model can also be adopted during the determination of hole quality attributes when the parameter settings are beyond a defined boundary, as the regression analysis value is very close to 1, and model performance is 4.99e-10. Peak current = 4 A, pulse-on time = 25 µs, pulse-off time=25 µs, and flushing pressure = 0.6 MPa were the optimum drilling parameters. In the initial hole, average burr length is 391.75 μm, and delamination of 539.3 μm is noticed. But burr formation is very negligible with delamination of 350.7 μm being observed with uniform circularity (0.979), low taper angle (−0.81354°), and TWR (0.000069 g/min) under optimum drilling conditions through this drilling approach.
Deselection of base-learners for statistical boosting—with an application to distributional regression
Authors: Strömer Annika , Staerk Christian , Klein Nadja , Weinhold Leonie , Titze Stephanie , Mayr Andreas
Published: December 2021

We present a new procedure for enhanced variable selection for component-wise gradient boosting. Statistical boosting is a computational approach that emerged from machine learning, which allows to fit regression models in the presence of high-dimensional data. Furthermore, the algorithm can lead to data-driven variable selection. In practice, however, the final models typically tend to include too many variables in some situations. This occurs particularly for low-dimensional data ([Formula: see text]), where we observe a slow overfitting behavior of boosting. As a result, more variables get included into the final model without altering the prediction accuracy. Many of these false positives are incorporated with a small coefficient and therefore have a small impact, but lead to a larger model. We try to overcome this issue by giving the algorithm the chance to deselect base-learners with minor importance. We analyze the impact of the new approach on variable selection and prediction performance in comparison to alternative methods including boosting with earlier stopping as well as twin boosting. We illustrate our approach with data of an ongoing cohort study for chronic kidney disease patients, where the most influential predictors for the health-related quality of life measure are selected in a distributional regression approach based on beta regression.
Facility profiling under competing risks using multivariate prognostic scores: Application to kidneytransplant centers
Authors: Lee Youjin , Schaubel Douglas E
Published: December 2021

The performance of health care facilities (e.g. hospitals, transplant centers, etc.) is often evaluated through time-to-event outcomes. In this paper, we consider the case where, for each subject, the failure event is due to one of several mutually exclusive causes (competing risks). Since the distribution of patient characteristics may differ greatly by the center, some form of covariate adjustment is generally necessary in order for center-specific outcomes to be accurately compared (to each other or to an overall average). We propose a weighting method for comparing facility-specific cumulative incidence functions to an overall average. The method directly standardizes each facility’s non-parametric cumulative incidence function through a weight function constructed from a multivariate prognostic score. We formally define the center effects and derive large-sample properties of the proposed estimator. We evaluate the finite sample performance of the estimator through simulation. The proposed method is applied to the end-stage renal disease setting to evaluate the center-specific pre-transplant mortality and transplant cumulative incidence functions from the Scientific Registry of Transplant Recipients.

Authors: Awal Iddrisu Mohammed , Senadjki Abdelhak , Nee Au Yong Hui
Published: December 2021

There is limited understanding concerning the practicable challenges that could impede the developmental process of railway infrastructure projects, and the possible negative effect of the Standard Gauge Railway (SGR) technology in Ghana. Given that the majority of the population are unfamiliar with the newly planned railway system. Our research intends to contribute towards the development of human capital and elevating the standard of living through the assertion of productive policies to ensure rapid infrastructure development by highlighting not only the socio-economic impact, but the negative impact of the railway infrastructure in the society. Also, this study discusses the possible challenges that could hinder the railway infrastructure development process. This study employs face-to-face interviews and Focus Group Discussions (FGDs) interview sessions that assimilate 35 respondents. Data collected is transcribed verbatim and analysed thematically. The findings reveal that corruption, unstable political discourse, lack of modern technology, and the impact of the Covid19 pandemic are among the critical challenges to hinder the progress and completion of the railway infrastructure development. By-laws should be designated ensuring that every uncompleted national project must be completed and not abandoned by the successive governments regardless of political differences.

Evaluator Perspective: An interview with Nicole Tujague
Authors: Rutter Anthea
Published: December 2021

Nicole tells us her story of coming to a decision to work more closely in the Indigenous space. She embarked on a journey of self-discovery which resulted in not only understanding herself but also her own people. One of her important discoveries was finding the Australian Evaluation Society (AES) and meeting people of like minds. She questioned projects where measurement is determined by the funder, not by the Indigenous people who are being impacted by the evaluation, and on the programmes which affect their lives. She has also realised that it is not enough to do evaluation in a culturally safe way, but that evaluation should be culturally safe and trauma informed. You need to understand the trauma histories of people and communities and that knowledge needs to be embedded in your methodology. Without that knowledge, you cannot expect to understand the community and its issues or produce outcomes that are healing.

Cervical Carcinosarcoma: Current Understanding on Pathogenesis, Diagnosis, Management and Future Perspectives
Authors: Shu Xinyao , Zhou Yuwen , Wei Guixia , Chen Xiaorong , Qiu Meng
Published: December 2021

Cervical carcinosarcoma (CCS) is a rare aggressive tumor which was referred to as a sarcoma initially with its morbidity less than 1% of all cervical cancers. Four theories have been proposed for the pathogenesis of CCS. The “metaplastic theory,” also called “monoclonal theory,” has been widely accepted so far. The most common clinical symptom of CCS is abnormal vaginal bleeding. CCS is much less common than the counterparts in uterine corpus and usually confused with uterine carcinosarcoma (UCS) or common cervical cancer. The management for CCS has been mainly extrapolated from studies of UCS or cervical cancers. However, CCS has its special anatomical position and biological behaviors and is usually diagnosed at an early stage than UCS. Currently, there is no consensus on the survival, management and prognosis factors of CCS. We reviewed and summarized the literatures regarding to the epidemiology, clinical presentations, pathogenesis, diagnosis and treatment of CCS for providing clinicians with comprehensive information to diagnose and treat this malignancy.
Preparing for the COVID-19 paediatric mental health crisis: A focus on youth reactions to caretaker death
Authors: Liang Naomi , Becker Timothy D , Rice Timothy
Published: December 2021

To promote clinician preparedness for working with children and adolescents who lost or will lose a parent or caretaker to COVID-19, findings from a review of the literature concerning youth reactions to parent and caretaker death and incapacitation were integrated with recent and emergent data concerning the COVID-19 pandemic. Children and adolescents who lose a parent or caretaker are at an increased risk of anxiety and depressive reactions and disorders, externalizing and health-risk behaviours, and substance use disorders. Particular aspects of the COVID-19 pandemic may influence these presentations and the risk of complicated grief. Youth with prior histories of adverse childhood experiences as well as boys and young men may require special considerations in formulation and planning. Tailored paediatric care based on the evidence advances accurate formulations and effective interventions for children and adolescents who suffer such a loss.
Silencing of FOS-like antigen 1 represses restenosis via the ERK/AP-1 pathway in type 2 diabetic mice

Published: December 2021

Restenosis is a major limiting factor for a successful outcome in type 2 diabetes (T2D) patients undergoing percutaneous coronary intervention (PCI). The aim of this study is to explore the role and regulatory mechanism of FOS-like antigen 1 (FOSL1) in restenosis in T2D. A T2D with restenosis mouse model was established by the combination of high-fat diet and streptozotocin injection and by wire-injury. High glucose (HG)-treated vascular smooth muscle cells (VSMCs) were used to mimic T2D in vitro. The results of quantitative real time PCR and western blotting demonstrated that the expression of FOSL1 was increased not only in T2D mice or HG-induced VSMCs, but also in T2D mice that underwent wire-injury. HE staining revealed that FOSL1 knockdown significantly reduced the intimal/media ratio of T2D mice after wire-injury. Silencing of FOSL1 reversed the promoting effects of HG treatment on viability, migration and inflammation reactions, and the inhibiting effect on the apoptosis of VSMCs. Inhibition of ERK/AP-1 pathway obtained similar patterns in HG-induced VSMCs. The activation of ERK/AP-1 pathway reversed the influence of FOSL1 knockdown on HG-induced VSMCs. Our findings indicate that silencing of FOSL1 may suppress restenosis via regulation of the ERK/AP-1 pathway in T2D mice, pointing out a potential therapeutic target to prevent restenosis in T2D.
Quality assessment of baby wet wipes
Authors: Cheriaa Rim , Boubaker Jaouachi
Published: December 2021

A wet wipe is a commercial product made of a fibrous substrate impregnated with a lotion that often comes folded and individually wrapped for convenience. The present work relates to wet wipes’ composition to clean the baby’s body. Wet wipes were produced from two spunlace nonwoven fabrics consisting of polyester/viscose and a wetting solution. Objective performance evaluation was carried out to determine the efficiency of the wipes for manufacturing and end uses. The lotion formula comprising surfactants, a solubilizer, preservative compounds, perfumes, and mainly purified water is selected to deliver the intended benefits of a baby wet wipe. Besides, physical, mechanical characteristics, and moisture management parameters of the wet wipe fabrics were measured. Optimal lotion (oil–water emulsion) stirring conditions were illustrated using optical microscopy. Lotion foamability appears as an undesirable phenomenon upon the manufacturing of the wet wipe. A mixture design, an extreme vertices design, was used to study the influence of the compounds on the foam volume. The relative contribution of each compound in the lotion to generate bath foam was discussed. Because wet media are more effective than dry media for surface cleaning, the optimum wet pick-up ensuring the best wiping efficiency about of 83.2% was found to be about 3 g of lotion for 1 g of fabric. Assuming that a wipe sample could be performed in less than 3 min, it was also confirmed that the developed wipe remains effective with a moisture content of 242% and can be comparable with other commercial wipes.

Background: Although the awareness, diagnosis, management of the complications associated with diabetes have improved in African countries over the past decade, surveillance activities in Tanzania and anecdotal reports from other African countries have suggested an increased prevalence of Charcot Neuroarthropathy (CN) over the past few years. Aim: To characterize the epidemiology and the clinical burden of CN in a large diabetes population in Tanzania, and to evaluate outcomes of persons with the condition. Methods: This was a prospective analytic cohort study conducted between January 2013 through December 2015. Following informed consent, patients were followed at the outpatient clinic. Detailed clinical assessments and documented presence of diabetic peripheral neuropathy (DPN), macrovascular disease and microvascular disease were recorded. Education and counseling were part of the follow-up program. Results: 3271 ulcerations were presented at the clinic during the 3-year study period. 571 (18%) met the case definition for CN; all patients had Type 2 diabetes. The prevalence for each of the years 2013, 2014, and 2015 was 19/1192 (1.6%), 209/1044 (20%), and 343/1035 (34%), respectively; the increases in the slope of the trendline was statistically significant ( P < .001). Conclusion: The prevalence of CN is increasing in the Tanzanian diabetes patient population, and is strongly associated with neuropathy. CN can lead to severe deformity, disability, and amputation. Due to the risk of limb amputation, patients with diabetes must seek immediate care if signs or symptoms appear and avoid delay in seeking medical attention. Early diagnosis of CN by caregivers is extremely important for successful outcomes.
Percutaneous Translymphocele Embolization of Retroperitoneal Lymphatic Leak
Authors: Bent Chris
Published: December 2021

Iodized oil-based lymphangiography (LAG) is a well-established diagnostic exam during the workup of postoperative lymphatic leaks. Computed tomography (CT) has been shown to be a useful complement to optimize treatment planning and can easily be performed after conventional LAG. The treatment options for lymphatic leaks include conservative dietary modification, sclerotherapy, embolization, and surgery. We present a case of a 48-year-old man who developed a symptomatic left retroperitoneal lymphatic fluid collection after left nephrectomy, complicated by postoperative retroperitoneal abscess. Retroperitoneal duct leak was confirmed via ultrasound-guided intranodal LAG and post-LAG CT. This leak was successfully managed with N-butyl cyanoacrylate glue embolization of the leaking lymphatics via fluoroscopic-guided catheterization of the leak via percutaneous access through the lymphatic fluid collection.

The therapeutic effectiveness of anticancer drugs with a selective target for the nucleus of cancer cells may be improved by experimental approaches. In this regard, the formulation of anticancer drugs is considered one of the best ways to improve their effectiveness in targeting cancerous tissues. To enhance the anticancer activity of 2-methoxy-estradiol (2 ME) for breast cancer, 2-methoxyestradiol loaded alpha lipoic acid nanoparticles have been formulated. The prepared formula was observed to be spherical with a nanometer-scale and low PDI size (.234). The entrapment efficiency of the 2ME-ALA NPs was 87.32 ± 2.21% with > 85% release of 2 ME within 24 h. There was a 1.2-fold increase in apoptosis and a 3.46-fold increase in necrosis of the MCF-7 cells when incubated with 2ME-ALA NPs when compared to control cells. This increased apoptosis was also associated with increased ROS and increased p53 expression in 2ME-ALA NPs treated cells compared to the raw-2 ME group. Evaluation of cell-cycle data showed a substantial arrest of the G2-M phase of the MCF-7 cells when incubated with 2ME-ALA NPs. At the same time, a dramatically increased number of pre-G1 cells showed the increased apoptotic potential of the 2 ME when administered via the proposed formulation. In the end, the differential upregulation of caspase-3, p53, and ROS in MCF-7 cells established the superiority of the 2ME-ALA-Ms approach in targeting breast cancer. In summary, these results demonstrate that 2ME-ALA NPs are an efficient delivery tool for controlling the growth of breast cancer cells.
Adaptive online terrain classification method for mobile robot based on vibration signals

Published: December 2021

To improve the accuracy of terrain classification during mobile robot operation, an adaptive online terrain classification method based on vibration signals is proposed. First, the time domain and the combined features of the time, frequency, and time–frequency domains in the original vibration signal are extracted. These are adopted as the input of the random forest algorithm to generate classification models with different dimensions. Then, by judging the relationship between the current speed of the mobile robot and its critical speed, the classification model of different dimensions is adaptively selected for online classification. Offline and online experiments are conducted for four different terrains. The experimental results show that the proposed method can effectively avoid the self-vibration interference caused by an increase in the robot’s moving speed and achieve higher terrain classification accuracy.
Optimization of the Milk-run route for inbound logistics of auto parts under low-carbon economy

Greenhouse gas emissions have brought serious negative impacts on human beings and organisms, so energy saving and emission reduction have been recognized by more and more people. Traditional Milk-run model seldom considers the factors of energy saving and emission reduction, and its routing optimization cannot meet the current needs of low-carbon economic development. On the basis of traditional Vehicle Routing Problem research, considering the fixed cost, time penalty cost, energy consumption cost and carbon emission cost of vehicles, the Milk-run model of distribution routing considering carbon emissions under time window constraints is studied. Then the improved ant colony algorithm is used to solve the constructed model. Finally, the order and related data of a company are used to verify the validity and practicality of the model and algorithm. Compared to the scanning method, the results show that not only the total journey distance has been shortened but also the total cost and cost of carbon emissions have been reduced. The optimization of distribution routing considering carbon emissions can reduce the distribution cost of logistics enterprises, respond to the call of low-carbon development in China and help to achieve a win-win situation of social and economic benefits.
Training police search and rescue teams: Implications for missing persons work
Authors: Ferguson Lorna , Gaub Janne E
Published: December 2021

Police search and rescue teams are crucial players in resolving missing person cases. Resultantly, police employ a host of training for search and rescue members in collaboration with institutions, organizations, and groups. Such training, however, has not been studied. This warrants attention as, in a time of police legitimacy crises and austerity policing, appropriate and quality police training for effective, efficient practices is imperative. Therefore, we examined the training needs and offerings for police search and rescue personnel, and their impact on search and rescue operations and work, through thematic analysis of interviews with 52 police search and rescue members from 17 agencies across Canada. Findings suggest there are no homogeneous, structured, or standardized training offerings for police search and rescue personnel. Instead, training varies within and across agencies and regions, and between officers and roles, as it is commonly based upon anecdotal experiences and in-house developed “best practices.” We discuss the implications of these findings for police search and rescue operations and work.
Pre-emptive memories: Anticipating narratives of Covid-19 in practices of commemoration
Authors: Mazzucchelli Francesco , Panico Mario
Published: December 2021

This article explores the narratives of the Covid-19 crisis in Italy, in the ways that they intersect with cultural memory processes. Moving from the hypothesis that the Covid-19 crisis, in Italy, has undergone two distinct narrative phases, we focus on the comparison between the forms taken, during the first lockdown, by an important (but also somehow divisive) memory ritual: the celebration of 25 April (the day that Italy was liberated from Nazi-Fascism) and the newly established commemorations of Covid-19 casualties. The aim is to observe the osmoses between two discursive domains (memory discourse vs emergency discourse). To do so, we propose the concept of “pre-emptive memory,” which can be defined as an act of—unwitting—anticipation, pre-figuration, and re-combination of the future cultural memory of an ongoing event in the present.
