Beyond emergency politics: Carl Schmitt’s substantive constitutionalism
Authors: Croce Mariano , Salvatore Andrea
Published: January 2023

This article problematizes the recent comeback of the exceptionalist jargon as it is conjured by both critics and sympathizers. While in the last decades governments across the globe had recourse to emergency measures to cope with far-reaching emergencies, from terrorism to the COVID-19 pandemic, the received view has it that political power takes advantage of states of emergency as they put themselves in the position to circumvent constitutional limitations. Carl Schmitt is claimed to be the major advocate of this conception of emergency politics in that he elaborated on the concept of the state of exception as the heart of the state political power. This article contends that the received view is doubly wrong. First, soon after his espousal of exceptionalism, Schmitt realized that emergency legislation is an ineffective and costly governmental device that should be transitory and is as unstable as the crisis it is meant to overcome. Second, the received view neglects how Schmitt came to his model of ultraconservative substantive constitutionalism as he maintained that the main task of politics is to protect the normative life of a limited set of state-sponsored institutions as well as the substantive contents they produce.
Who You Live With Matters: Living Arrangements and Life Expectancy With the Evidence From Eighteen-Year Follow-Up Data
Authors: Wang Juwen , Chiu Chi-Tsun
Published: January 2023

No study has quantified the association between living arrangements and life expectancy in Taiwan. This study aims to fill this gap by investigating life expectancy among various types of living arrangements in Taiwan. We applied the Taiwan Longitudinal Study on Aging, a longitudinal survey of a nationally representative sample of older adults in Taiwan. We conducted hazard models to estimate the life expectancy of older adults by gender, at age 60, and in 12 different types of living arrangements. Our results have confirmed an association between living arrangements and life expectancy among older Taiwanese. Older adults who live with their parents enjoy a longer life expectancy. In contrast, living with a caregiver or in nursing institutions, and living only with their son/son-in-law have a relatively shorter life expectancy. Living arrangements suggested the allocation of family resources and support, and the demand/need for health care differs across living arrangements.
Political Disputes and Religious Fusions: From Countering to Understanding the Naga and Zo Narratives of Self-Determination
Authors: Ngaihte Samuel G
Published: January 2023

One of the recurring themes pertaining to the ‘Northeast’ of India is the question of ethno-political unrest prevalent in the region. While the lens through which this ‘unrest’ is interpreted is diverse, the language of ‘insurgency’ continues to be the privileged perspective. This has led to the reductionist perception that the issue is a particularly postcolonial phenomenon, and in the Naga and Zo Hills, an aftermath of the Christian mission influence in these areas. This perception is problematic as it offers no conceptual space to account for the historical particularities that have shaped these respective struggles, and is unable to imagine a way beyond countering to understanding in seeking honourable and sustainable resolutions. This paper explores the particularities of the Naga and Zo ‘insurgencies’, particularly in the context of their encounter with the British Empire and Christian missionaries, to seek substantive insights about dialogic transformation as a possible way forward.

Published: January 2023

The evaluation results of wind energy resources directly affect the economic benefits and healthy development of wind farms. Therefore, a high-resolution wind resource assessment method for wind farms based on mesoscale atmospheric model and CFD technology is studied to accurately simulate relevant data of wind resources and improve the assessment effect. The mesoscale WRF numerical model is used to solve the regional data of wind farms and obtain the mesoscale meteorological analysis data. According to the solution results of the mesoscale atmospheric model, the wind speed profile is established, the boundary conditions and initial conditions are extracted, and the CFD micro scale model is input to obtain the wind speed and wind speed frequency at the height of the fan impeller. In order to improve the accuracy of numerical simulation of micro scale CFD model, the large eddy simulation method is used to simulate the operation of wind farms. Complete theoretical power generation evaluation based on wind speed, wind speed frequency and generator power. The experimental results show that this method can accurately simulate wind resources and accurately evaluate the theoretical power generation of wind farms. The wind farm is rated as Level 3, and the wind frequency is mainly between 4 and 10 m/s. This method can ensure that the wind farm can generate electricity all year round without damaging the wind speed.

Published: January 2023

This study investigates which factors can influence bicycle accidents for a variety of age groups at the traffic analysis zone level. The cyclists were divided into four age groups: child, young, adult, and elderly. To accommodate for the potential variation in the influence of exogenous factors for these age groups, we utilized the multivariate Poisson gamma mixture model. The formulated model not only incorporates the heterogeneity and over-dispersion of the unobserved factors but also allows for the variance of the covariance between the age groups among the zones. The zone-level variables considered in this study include sociodemographic characteristics, socioeconomic characteristics, the built environment, road network characteristics, and traffic characteristics. The model was estimated using bicycle accident data for the year 2011 in Nagoya, Japan. The estimated results clarify the impacts of the explanatory variables for the respective age groups. Children tend to experience more accidents in their residential zones, while the young and adult age groups have more accidents in zones that have many companies. All age groups are more likely to have accidents in the area of many shops. The elderly group is greatly affected by both the number of bicycle trips and its spatial spillover effect, implying that they are most prone to bicycle accidents among all age groups. The findings of this research can assist decision-makers in making proactive decisions to improve bicycle safety.

Authors: Yang Yuwei , Chen Jiayi , Ye Jiao , Chen Jun , Luo Yinjie
Published: January 2023

The parking cruising problem can be attributed to the unbalanced spatial parking space occupancy in the parking lot with multiple trip purposes and high traffic volumes, and it has already become an obstacle to improving travel efficiency. This study aims to investigate the reasons for the unbalanced occupancy of parking spaces and develop strategies to achieve spatial equilibrium by reducing parking cruising time. A field survey is first conducted to analyze the factors influencing parking space choice behavior, such as searching distances, walking distances, parking price, and parkers’ attributes. Based on the survey, a mixed logit model is calibrated to reveal parking space choice patterns of different parkers. Afterwards, the parking lot is divided into three zones based on searching distances and walking distances, using the K-means algorithm. According to the results, a simulation-based optimization model is then established, for minimizing the variance of average occupancy. An optimal pricing strategy is obtained at last. A case study in Nanjing, China, is conducted to verify the feasibility and rationality of the proposed method. The difference between weekdays and weekends is explored. The results show that, with the optimal strategies, the standard deviation of average occupancy in each zone decreases by 39.52% during weekends and 42.29% during weekdays. Finally, political implications and recommendations on the layout design of facilities and the adoption of differential parking pricing strategies are provided.
#BREAKING local news: Twitter use in a large media market
Authors: Russell Frank M. , Hernandez Miguel , Sanchez Korryn
Published: January 2023

This study concerns Twitter use in a large local news market. Nonprofit newsrooms and a regional newspaper used replies to engage in reciprocal exchanges with audiences, but broadcasters used retweets, hashtags, and mentions for branding. News media differed in attention to news topics valued by audiences, with resource-constrained local newspapers overemphasizing sports. Attention to weather and crime were predictors of audience sharing of tweets, but sports posts were less likely to be liked or retweeted.
Design and implementation of passivity-based controller for active suspension system using port-Hamiltonian observer
Authors: Sistla Pramod , Chemmangat Krishnan , Figarado Sheron
Published: January 2023

The objective of this study is to design and implement an observer for quarter-car active suspension system in Port-Hamiltonian form. A novel state observer is designed for active suspension system modelled in port-Hamiltonian form to estimate the states in presence of road disturbances. The observer is designed considering suspension deflection alone as the output, which is an easily measurable output. Performance of the proposed observer is evaluated experimentally with road disturbance input mimicking a sudden bump and a continuously varying road input, and proven to be effective in minimising the error dynamics in presence of bounded unmodelled disturbances. To prove the effectiveness of the state-estimator, an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) designed using the desired physical properties of the closed-loop system is implemented using the observer states. Experimental results of the controller implemented using the designed state observer show good improvement in the ride comfort, ride stability and suspension stroke of the active suspension system, which proves the effectiveness of the proposed port-Hamiltonian observer in terms of minimising the error dynamics.

Published: January 2023

Body panels have a direct influence on the static and dynamic stiffness of the body-in-white. With the introduction of CFRP in automotive body, these panels have ushered in the potential of being designed with variable-stiffness. However, due to the inherent complexity of variable-stiffness design and the need to integrate all panels to account for their interaction on BIW, the related design issue has not been solved. This paper reports a design method to achieve the successive optimization of the thickness distribution and stacking sequence for body panels, as well as ensure basic manufacturing and blending requirements of design results. This method was applied to the virtual design of the roof, floor, outer and inner side panels of a body-in-white. Compared with original constant-stiffness CFRP components, a 16.4% weight reduction was attained, the torsional and bending stiffness, first-order torsional and bending frequencies were enhanced by 5.0%, 10.9%, 4.7%, and 7%, respectively.
Brain-computer interfaces, disability, and the stigma of refusal: A factorial vignette study
Authors: Sample Matthew , Sattler Sebastian , Boehlen Wren , Racine Eric
Published: January 2023

As brain-computer interfaces are promoted as assistive devices, some researchers worry that this promise to “restore” individuals worsens stigma toward disabled people and fosters unrealistic expectations. In three web-based survey experiments with vignettes, we tested how refusing a brain-computer interface in the context of disability affects cognitive (blame), emotional (anger), and behavioral (coercion) stigmatizing attitudes (Experiment 1, N = 222) and whether the effect of a refusal is affected by the level of brain-computer interface functioning (Experiment 2, N = 620) or the risk of malfunctioning (Experiment 3, N = 620). We found that refusing a brain-computer interface increased blame and anger, while brain-computer interface functioning did change the effect of a refusal. Higher risks of device malfunctioning partially reduced stigmatizing attitudes and moderated the effect of refusal. This suggests that information about disabled people who refuse a technology can increase stigma toward them. This finding has serious implications for brain-computer interface regulation, media coverage, and the prevention of ableism.
Just another clickbait title: A corpus-driven investigation of negative attitudes toward science on Reddit
Authors: Batchelor Jordan
Published: January 2023

The public understanding of science has produced a large body of research about general attitudes toward science. However, most studies of science attitudes have been carried out via surveys or in experimental conditions, and few make use of the growing contexts of online science communication to investigate attitudes without researcher intervention. This study adopted corpus-based discourse analysis to investigate the negative attitudes held toward science by users of the social media website Reddit, specifically the forum r/science. A large corpus of comments made to r/science was collected and mined for keywords. Analysis of keywords identified several sources of negative attitudes, such as claims that scientists can be corruptible, poor communicators, and misleading. Research methodologies were negatively evaluated on the basis of small sample sizes. Other commenters negatively evaluated social science research, especially psychology, as being pseudoscientific, and several commenters described science journalism as untrustworthy or sensationalized.
Finite element modelling of exponentially graded composites with microstructure
Authors: Barrage Ryan , Potapenko Stanislav , Polak Maria Anna
Published: January 2023

Composite material properties are dependent on their microstructure. To adequately model these microstructural effects, a formulation of elasticity that accounts for microstructural effects must be considered. Size-dependent behaviour is an inherent property of such materials, resulting in a need for non-classical continuum theories for adequate characterization. A three-dimensional model for an exponentially graded composite with microstructural effects is developed under the framework of Cosserat elasticity. The mixed boundary value problem is formulated and solved through the finite element method, and implemented in the commercial software Abaqus through two user developed elements. Recovery of the classical limit for the Dirichlet problem is discussed as an initial model validation until complete experimental measurements can be conducted.

Published: January 2023

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver. Although the RNA modification N6-methyladenine (m6A) has been reported to be involved in HCC carcinogenesis, early diagnostic markers and promising personalized therapeutic targets are still lacking. In this study, we identified that 19 m6A regulators and 34 co-expressed lncRNAs were significantly upregulated in HCC samples; based on these factors, we established a prognostic signal of HCC associated with 9 lncRNAs and 19 m6A regulators using LASSO Cox regression analysis. Kaplan-Meier survival estimate revealed correlations between the risk scores and patients’ OS in the training and validation dataset. The ROC curve demonstrated that the risk score-based curve has satisfactory prediction efficiency for both training and validation datasets. Multivariate Cox’s proportional hazard regression analysis indicated that the risk score was an independent risk factor within the training and validation dataset. In addition, the risk score could distinguish HCC patients from normal non-cancerous samples and HCC samples of different pathological grades. Eventually, 232 mRNAs were co-expressed with these 9 lncRNAs according to GSE101685 and GSE112790; these mRNAs were enriched in cell cycle and cell metabolic activities, drug metabolism, liver disease-related pathways, and some important cancer related pathways such as p53, MAPK, Wnt, RAS and so forth. The expression of the 9 lncRNAs was significantly higher in HCC samples than that in the neighboring non-cancerous samples. Altogether, by using the Consensus Clustering, PCA, ESTIMATE algorithm, LASSO regression model, Kaplan-Meier survival assessment, ROC curve analysis, and multivariate Cox’s proportional hazard regression model analysis, we established a prognostic marker consisting of 9 m6A regulator-related lncRNAs that markers may have prognostic and diagnostic potential for HCC.
Using a protection motivation theory framework to reduce vaping intention and behaviour in Canadian university students who regularely vape: A randomized controlled trial
Authors: Salmani Babac , Prapavessis Harry
Published: January 2023

Using Protection Motivation Theory (PMT), we examined the effect of threat appraisal information (perceived vulnerability-PV and perceived severity-PS) to reduce vaping intentions, and in turn reduce vaping use. Canadian university students ( n = 77) who vape regularly were randomized to either PMT or attention control treatment conditions. Data were collected at baseline and 3 time points after the intervention: Day 7, Day 30, and Day 45. Participants assigned to the PMT group showed significant increases in PV, PS, and intentions to vape less ( p ⩽ 0.05) compared to those in the attention control group. Less convincing evidence was found between treatment groups for vaping use. PS and PV predicted vaping intentions, whereas vaping intentions did not predict vaping use. It is suggested through this study that the threat appraisal components of PMT can be successfully manipulated to reduce the intentions to vape and to a lesser extent reduce vaping use among University vapers.
Applying control-value theory for examining multiple emotions in L2 classrooms: Validating the Achievement Emotions Questionnaire – Second Language Learning
Authors: Shao Kaiqi , Stockinger Kristina , Marsh Herbert W. , Pekrun Reinhard
Published: January 2023

This study used Pekrun’s control-value theory (CVT) as a framework to validate the Achievement Emotion Questionnaire – Second Language Learning (AEQ-L2L) for assessing eight student emotions in second language (L2) learning. We tested and validated the instrument in two samples using three waves of data, with a total number of 1,021 Chinese university students. Item and scale statistics indicate the AEQ-L2L is reliable. Moreover, single- and multi-group confirmatory factor analysis supported the hierarchical four-factor component structure of L2 emotions in and across the two student groups. Furthermore, multi-model comparison indicated that language emotions are best represented by considering both the distinctiveness of the eight examined emotions and their component structure. Finally, latent correlation analysis demonstrated the external validity of the AEQ-L2L in terms of linkages with appraisals, motivation and language achievement. Findings are discussed by highlighting the unique value of the AEQ-L2L for investigating a broad range of emotions in language education.
Seismic responses of transmission tower-line system under multi-component ground motions
Authors: Wei Wenhui , Hu Ying , Pi Yong Lin
Published: January 2023

In this study, shaking table tests, theoretical research, and finite element modeling analysis were conducted on seismic responses of a transmission tower-line system under multi-component ground motions. The rocking component of ground motion was determined from the original seismic record by the wavelet analysis. The shaking table tests for scale models (single tower and tower-line system) that satisfy the similarity ratio of an actual tower-line system, were performed under multiple directions of motion. Dynamic equations under multi-component (horizontal, coupled horizontal, and tilting (CHT), and coupled vertical, horizontal, and tilting (CVHT)) ground motions were first derived in theoretical studies. The finite element model based on the actual transmission tower line system was built, and the response of the system under the identical working condition was calculated. It is found that the rotational component of the ground motion cannot be overlooked and significantly impacts the seismic response of the tower-line system, which is reflected especially as the vertical motion is coupled. The tilting ground motion, the additional second-order effect, and the foundation tilting jointly cause the increase in the response amplitude and significant asymmetric displacement effect. Since this effect of tilting ground motions, the weakening effect of the transmission line to reduce the responses for the displacement and acceleration of the tower-line system is also weakened. It is, therefore, essential to consider the adverse effects of multi-component ground motions on the designing of transmission tower systems in high-intensity areas.
Inpatient management of complicated mTBI with the BIG assessment tool: Review and summary of the evidence
Authors: Barber Kimberly R , Wasfie Tarik
Published: January 2023

Introduction

The management of mild traumatic brain injury has evolved through the years with an emphasis on the safe discharge of patients given current resources. In this article, we discuss key studies published in the past 12 years that have influenced the direction of complicated mild traumatic brain injury (cmTBI) management. We summarize the evidence on the utilization of the Brain Injury Guideline (BIG) algorithm.

Methods

An independent literature search was conducted on the BIG, updated versions of BIG, and the prognostic studies of adult mild traumatic brain injury admissions cited by the BIG articles. Evidence resources included the search engines of PubMed, Medline, Ovid, Cochrane Library, and Google Scholar bibliographic databases of items published between 1 January 2010 and 30 December 2021. The evidence focused on BIG and its modified versions, as a potential risk assessment tool for discharging mTBI patients early.

Results

Studies supporting the BIG algorithm prior to 2019 presented evidence with serious limitations to their findings. These limitations threaten their veracity and fail to support the efficacy or validation of the BIG algorithm's utilization for mTBI patient management.

Conclusion

The lack of rigor in the BIG algorithm studies suggest the research is currently insufficient to support early discharge and research needs to continue on modified versions of the tool before its widespread use.
Application of surgical guide for pre-drilling for the successful placement of orthodontic mini-screws using CAD/CAM technology in two cases
Authors: Liang Wenyong
Published: January 2023

An increasing number of clinicians have been utilising orthodontic mini-screws as temporary anchorage devices (TAD) in their practices, but variable successful rates have been reported. Here, we introduce a practical approach to inserting mini-screws successfully. Using computer-aided design (CAD) and computer-aided manufacturing (CAM) technology, the surgical guide for pre-drilling was designed and fabricated and mini-screws were placed following pre-drilling holes in two cases. Two Ø2.0 × 10.0-mm mini-screws were inserted into the prepared holes in the mandibular buccal shelf (MBS) on both sides with a hand driver to distalise the lower molars for Class III correction. The treatment was done successfully, after 12 months of treatment in one case. Two Ø1.6 × 8.0-mm mini-screws were inserted into the prepared holes in the mandibular alveolar process in another case with congenital absence of lower right second premolar. One mini-screw was in the buccal alveolar process between the mandibular right canine and first premolar and the other in the lingual alveolar process between the mandibular right first premolar and second primary molar. The lower right molars would be protracted to close the space left after the extraction of the primary molar using the two mini-screws. The case was still in treatment.

Published: January 2023

The south building of Huadong Hospital is a well-known historic building in Shanghai, China. In August 2021, the building was lifted by 1.30 m to correct the subsidence caused by long-term use and to expand the usable space of the building. To ensure structural safety during uplifting of the historic building, a structural health monitoring system is devised to monitor the overall status of the structure and the state of critical components. The structural health monitoring system comprises sensor, data acquisition, and data management systems. The content that is monitored includes vertical displacement, horizontal displacement, inclination, differential settlement, cracks, strains, and acceleration. The overview and uplifting scheme of the historic building are first introduced. The monitoring system’s design and sensor installation are then thoroughly discussed, followed by monitoring data analysis to investigate the state of the structure before and after uplifting. Furthermore, a structural safety assessment based on multisource monitoring data and neural networks is conducted. Huadong Hospital’s south building is currently the largest uplifted historic building in terms of construction area in China. The building’s structural health monitoring system played an exemplary and promoting role in structural health monitoring during uplifting of historic buildings, and it also has referential significance for similar engineering projects.
How Much Data for the Political Theorist? On the Argumentative Normative Behaviourism
Authors: Perez Nahshon
Published: January 2023

Jonathan Floyd’s work explores the ways in which political theory can use empirical data to answer a fundamental question: what is the best kind of a contemporary regime? The goals of the current article are to understand Floyd’s important argument, to clarify the argument’s main attributes, and to suggest that the argument cannot rely solely on empirical data: even if all the conditions that are necessary for Floyd’s framework present themselves, his approach still requires substantial theoretical, normative, or philosophical foundations. I argue that it is not possible to rely on empirical data to circumvent political philosophising; the justification for such reliance itself requires substantial philosophical arguments. Regardless, Floyd’s project is a leading example of the benefits of bringing political theory and political science closer to each other.
In Contemplating Loss: The Creative Power and Possibility of Suffering
Authors: Yoo Joanne
Published: January 2023

Even as the world continues to be rocked by new COVID-19 variants, everyday life is slowly returning to normal. The crazy stockpiling of groceries and the stay at home mandates seemed to have occurred a lifetime ago, revealing how quickly we have moved on. We muddle through the uncertainty, but by moving on too quickly, we slip back into old ways. By taking our everyday freedoms for granted, we overlook the opportunity to forge new paths. To linger in the suffering evoked by uncertainty, however, is to harness the power of change to craft a more timeless and expansive path.

Published: January 2023

Background: Varicose pubic collateral veins are a rare phenomenon secondary to obstruction of the common femoral vein, left external iliac, or common iliac vein. This article aims to describe the clinical case of a 75-year-old female patient who presented with varicose collateral suprapubic veins.

Case report: A 75-year-old female patient from a rural area in Colombia presented to the emergency department complaining of a 4-day history of edema, erythema, and pain in the suprapubic region. The patient presented with large varicose veins in the suprapubic region with erythema, warmth, and pain on palpation. A computer tomography scan of the abdomen and pelvis showed suprapubic varicose veins and contrasted in venous phase ruled out iliac vein obstruction. To rule out paraneoplastic syndrome, tumor markers, a transvaginal ultrasound, esophagogastroduodenoscopy and rectosigmoidoscopy were obtained and found to be negative. Anticoagulation with warfarin 5 mg daily and bridge therapy with enoxaparin was initiated.

Conclusion: We presented the case of a patient with varicose collateral suprapubic veins of unknown origin, who received anticoagulation with warfarin and analgesic management with subsequent resolution of symptoms.
Emerging Need for PROMs to Measure the Impact of Spine Disorders on Overall Health and Well-being: Measuring Expectations as an Example for Lumbar Degenerative Spondylolisthesis

Published: January 2023

Background: Assessing the impact of spine disorders such as lumbar degenerative spondylolisthesis (LDS) on overall health is a component of quality of care that may not be comprehensively captured by spine-specific and single-attribute patient-reported outcome measures (PROMs). Purpose: We sought to compare PROMs to the Lumbar Surgery Expectations Survey (“Expectations Survey”), which addresses multiple aspects of health and well-being, and to compare the relevance of surgeon-selected versus survey-selected Patient-Reported Outcomes Measurement Information System (PROMIS) items to LDS. Methods: In a cross-sectional study, 379 patients with LDS preoperatively completed the Expectations Survey, Numerical Rating Pain Scales, Oswestry Disability Index (ODI), and PROMIS computer-adaptive physical function, pain, and mental health surveys. Expectations Survey scores were compared to PROMs with correlation coefficients (indicating strengths of relationships) and probability values (indicating associations by chance). Surgeons reviewed physical function questions to identify those particularly relevant to LDS. Results: Patients’ mean age was 67 years, 64% were women, and 83% had single-level and 17% had multiple-level LDS. Probability values between the Expectations Survey and PROMs were reliable, but strengths of relationships were only mild to moderate, indicating PROMs did not comprehensively capture the impact of LDS. None of the surgeon-selected PROMIS physical function questions were posed to patients. Conclusion: This cross-sectional study found PROMs to be reliably associated but not strongly correlated with the Expectations Survey, which addresses the whole-patient impact of LDS. New measures that complement PROMIS and ODI should be developed to capture the whole-person effects of LDS and permit attribution of LDS treatments to overall health.

Published: January 2023

Stretch woven fabrics are known for their elastic and recovery properties. To date, they found many interesting applications from simple jeans to complex fabric structures with functional properties for example bi-stretch auxetic woven fabrics, compressions garments and stretchable textile carriers for healthcare applications. Many studies have been carried out on the physical, mechanical and comfort properties of stretchable knitted and woven fabrics. However, to identify combination of yarns with different stretch properties and other design parameters required to meet multiple objectives in the production and usage of bi-stretch woven fabrics is an area that has been taken up by fabric scientists recently. This study compared the effect of using elastic yarns and alternate elastic and non-elastic yarns in warp on the properties of bi-stretch woven fabrics while using elastic yarns in weft direction. It was found that shrinkage of the fabrics made of elastic yarns was higher along the warp direction as compared to that in weft direction due to shrinkage balancing effect; however, in case of fabrics made of alternate elastic and non-elastic yarns in warp the shrinkage behavior was exact opposite. The comparison of shrinkage for different weave patterns revealed that satin had the highest shrinkage followed by twill and plain, due to least number of interlacements in satin among these three patterns.

Authors: Chen Mingfang , Mo Xiang , Zhang Yongxia , Wang Seng
Published: January 2023

To enhance the environmental adaptability of the quadruped robot and realize its stability in terrain with obstacles, this paper studies the fusion of sensor information feedback and bio-reflection control algorithm. First, a central pattern generator (CPG) that generates basal rhythmic movements is constructed. Secondly, a simplified foot end that can be used to identify the touchdown and obstacle information is designed. To enhance the stability of the quadruped robot during the flexor reflex process and avoid the problem of solidification in the reflex process, the foot touch signal was introduced into the flexor reflex algorithm, which enhanced the flexibility of the reflex process. To avoid secondary collisions with obstacles, the postswing reflection process is optimized, and active obstacle avoidance is realized after the obstacle is touched. Finally, the organic fusion of sensor information feedback, CPG control network, and bio-reflection control algorithm is realized. The simulation results show that the robot’s ability to overcome obstacles is improved, the number of reflections is less, and the reflection process is more stable.
A label- and enzyme-free fluorescence assay based on thioflavin T–induced G-quadruplexes for the detection of telomerase activity
Authors: Chen Zhe , Wang Yunxia
Published: January 2023

A label- and enzyme-free fluorescence assay based on thioflavin T–induced G-quadruplexes is developed to sensitively and specifically detect telomerase activity. Thioflavin T has a dual role as an efficient inducer and fluorescent probe, and the incorporation of thioflavin T into the thioflavin T–induced G-quadruplexes results in an intense fluorescence enhancement. In the presence of thioflavin T and K+, G-quadruplexes are formed by elongation of the telomerase substrate primer that is catalyzed by telomerase extracted from cancer cells. Thus, the telomerase activity in cancer cell extracts can be evaluated by measuring the thioflavin T fluorescence. More importantly, thioflavin T can specifically recognize and bind to G-quadruplexes, whereas it cannot recognize single- and double-stranded DNAs, which leads to the thioflavin T–based fluorescence assay exhibiting a reduced background and improved signal-to-noise ratio. As a result, the proposed assay has the linear range from 5 to 200 HeLa cells and the detection limit is 34 HeLa cells, which holds great potential for use in the detection of telomerase activity and the diagnosis of cancer.

Published: January 2023

Background:

Robotic-assisted simple prostatectomy (RASP) proved to be a sound and effective procedure for bladder outlet obstructive symptoms relief. Routinely, the transvesical (Freyer) or transcapsular (Millin) techniques are performed. A novel approach of near-infrared fluorescence imaging (NIFI)-guided urethra-sparing robot-assisted prostatectomy (Madigan) was recently introduced.

Objectives:

The aim of our study was to evaluate the long-term functional outcomes between the Millin, Freyer, and Madigan RASP.

Design:

This is a single-center, retrospective evaluation of a prospectively maintained Institutional Review Board–approved database.

Methods:

Data from patients who have undergone RASP in our center were prospectively collected. Demographics, prostate size, and preoperative flowmetry parameters were assessed. Questionnaires such as International Index of Erectile Function (IIEF), and International Consultation on Incontinence Questionnaire (ICIQ), International prostatic symptoms score (IPSS) with its quality of life (QoL) score, Male Sexual Health Questionnaire (MSHQ), Overactive bladder questionnaire (OABQ) were administered to every patient preoperatively and during follow-up. We tested composite outcomes (trifecta) defined as a combination of postoperative Q-max >15 ml/s, IPSS score < 8, and absence of complications. We also tested a pentafecta which keeps in account the persistence of antegrade ejaculation (MSHQ > 0) and the erectile function maintenance (∆IEEF < 6).

Results:

Median follow-up was 36 months. Millin, Madigan, and Freyer procedures were performed in 37 (51%), 18 (25%), and 17 (24%) cases, respectively. Trifecta was achieved in 43 (60%) patients. Preoperative ICIQ, postoperative IPSS, postoperative OABQ, and QoL were significantly different between groups (all p < 0.02). Pentafecta was achieved by 14 (20%) patients. The pentafecta group showed a statistically significant advantage in terms of postoperative IPSS and MSHQ ( p < 0.01).

Conclusion:

RASP provides an effective and durable relief of obstructive symptoms at long-term follow-up, regardless of the technique, achieving the trifecta in the majority of the patients. The Madigan technique is significantly related to the pentafecta achievement.
Prostate cancer among South Asian men in the United Kingdom: A systematic review
Authors: Panayi Zoe , Srirangam Shalom J
Published: January 2023

Introduction:

Rates of prostate cancer (PC) vary considerably between ethnic groups worldwide, and migratory studies have demonstrated the importance of both inherent and environmental influences. Healthcare systems also differ significantly worldwide, and comparisons of PC data between the United Kingdom and America have previously shown contradictory conclusions among ethnic groups. The South Asian population (SA) is the most predominant UK ethnic minority group.

Aims:

To systematically explore and critically analyse the available UK-based evidence regarding PC among SA men. Specifically, to review research that assesses the following factors: PC incidence, disease characteristics, treatment and survival outcomes.

Results:

The existing evidence suggests that UK SA men have a lower PC incidence and younger age at diagnosis, in comparison with White men in the United Kingdom. Contrasting evidence is presented in studies that separately analyse men originating from India, Pakistan and Bangladesh. There is insufficient and contradictory evidence regarding whether SA men show altered PC disease characteristics or have differential survival rates. The evidence is limited regarding PC treatment; however, this indicates that SA men are less frequently treated surgically compared to White men

Conclusion:

Further high-quality research is required focusing on accurate ethnicity allocation, analysis of separate SA origin countries, socio-economic adjustment, subgroup analysis of treatment in low-risk PC and identifying the support needs of SA minorities with PC. This will help to ensure that ethnic minorities with PC are appropriately diagnosed, counselled and treated

Equity versus efficiency: A spatial analysis of residential aged care resources in Beijing
Authors: Bi Xiangyang , Li Mo
Published: January 2023

Based on data collected from residential aged care facility websites and the Sixth China National Population Census, this paper studies the spatial pattern of Beijing's aged care resources in the framework of spatial location of public facilities. The results show that at the township/street level, the overall distribution of public aged care resources is relatively balanced, showing positive spatial autocorrelation, while private aged care resources show partially negative spatial autocorrelation. Spatial regression analysis indicates that the dispersed and clustered distribution of private aged care resources are more sensitive to the density of local elderly population, although the distribution of two types of resources is affected by the absolute number of service objects in respective administrative areas. In short, the spatial distribution pattern of public and private aged care resources reflects the contrast between efficiency and equity in providing aging care in China, a fact that is shaped by both administrative and market forces.
Humanitarian crisis in Afghanistan: Changing global dynamics and Pakistan's policy choices
Authors: Khan Muhammad Fahim , Hassan Asad , Raza Aamer
Published: January 2023

Afghanistan has gone through a series of turmoils propelled by internal conflicts and foreign interventions. As the neighbor that shares Afghanistan's longest and, arguably, most important neighbor, Pakistan cannot remain aloof from the developments in Afghanistan. During the past 40 years, Pakistan has supported Mujahiddin against Soviets in 1980s, recognized the Taliban regime in 1990s, and joined the US-led war on terror in the 2000s and 2010s. The article argues that the current Afghan imbroglio confronts Pakistan with a peculiar set of challenges due to the lack of legitimacy of the Taliban regime in the eyes of foreign powers and the humanitarian crisis in Afghanistan. We contend that Pakistan needs to engage with the Taliban and use its leverage to make the Afghan government under the Taliban more inclusive. The same will help to resolve the miseries of the Afghan population.
Extending the Contacts Breaks the Flow

In this news and views, we discuss our recent publication where we described how ER-PM membrane contact sites (MCS) are modulated during store operated calcium entry (SOCE). We also examine why enforcing ER-PM MCS by tethering proteins does not not enhance, but rather inhibits SOCE.
Research-to-Resource: Introducing Retrieval Practice in Jazz Pedagogy
Authors: Wellmann Mario , Skillicorn Alexa Torres
Published: January 2023

Evidence-based practice in education is the implementation of research-supported teaching tools to enhance students’ learning. Retrieval practice is among the top performing learning techniques in scientific literature, with decades of research supporting its incorporation in educational contexts. Testing enhances posterior performance of the studied material, compared with restudying for an equivalent amount of time. Its benefits extend beyond long-term retention: it diminishes anxiety, fosters learning transfer, and reduces the negative consequences of acute stress on memory retrieval, among other desirable outcomes. Its implementation is inexpensive as it requires only minimal supplies. Despite research indicating the potential of retrieval practice to significantly improve student learning, this technique is rarely implemented in music education contexts. The main objective of this work is to propose the incorporation of retrieval practice in jazz performance education. The article outlines a description of retrieval practice, characterizes optimal conditions for its application, and provides step-by-step examples of its use in the classroom.
Vocal Modeling: A Review of Literature
Authors: Hinkley Sandy P.
Published: January 2023

Music educators typically use a variety of strategies to teach their subject matter, one core practice of which is modeling. Vocal modeling is a type of aural demonstration, with uses ranging from pitch matching and song instruction to vocal tone building and musicianship development. In early studies, researchers primarily studied the effects of gender and octave-varied vocal models with younger children. Over the years, researchers extended these investigations with more diverse populations and also explored the effects of vibrato, timbre, and mistuned stimuli. The purpose of this review of literature was to provide a summary of vocal model research with a discussion of findings and pedagogical implications for music educators. Recommendations for future research are also included.
Nano fertilizer synergist effects on nitrogen utilization and related gene expression in wheat
Authors: Yang Min , Dong Chengwu , Shi Yan
Published: January 2023

The application of nano materials is one of the current hot spots in agricultural production. The aim of this work was to evaluate the effects of different nano fertilizer synergists on nitrogen (N) utilization and related gene expression in wheat. The experiments were carried out in pot and field conditions at the West-Coast Economic New Area experimental base and Greenhouse of Qingdao Agricultural University. Seven treatments were set up: CK (compound fertilizer), T1 (compound fertilizer + 0.3% nano carbon synergist), T2 (compound fertilizer + 0.3% nano calcium carbonate synergist), T3 (compound fertilizer + 0.3% composite nano synergist), T4 (70% compound fertilizer + 0.3% nano carbon synergist), T5 (70% compound fertilizer + 0.3% nano calcium carbonate synergist), T6 (70% compound fertilizer + 0.3% composite nano synergist). The results showed that compared with CK, the N accumulation of T1, T2, T3, T4, T5 and T6 increased by 40–50%, 30–40%, 55–65%, 20–30%, 15–20% and 30–40%, respectively; and the N use efficiency increased by 12–19%, 9–18%, 16–22%, 5–17%, 4–16% and 10–20% respectively. And the gene expression levels of TaNRT2.2, TaNRT2.3, TaGS1 and TaGS2 in the treatments with synergistic phosphate fertilizer were significantly higher than those in the CK. The application of nano fertilizer synergist can significantly improve N accumulation, N use efficiency, and promote the expression of genes related to N transport and metabolism.
