Investigating Temporal Characteristics of Polarimetric and Electrical Signatures in Three Severe Storms: Insights from the VORTEX-Southeast Field Campaign
Authors: Sharma Milind , Tanamachi Robin L. , Bruning Eric C. 
Published: April 2024

Abstract
The dual-polarization radar characteristics of severe storms are commonly used as indicators to estimate the size and intensity of deep convective updrafts. In this study, we track rapid fluctuations in updraft intensity and size by objectively identifying polarimetric fingerprints such as ZDR and KDP columns, which serve as proxies for mixed-phase updraft strength. We quantify the volume of ZDR and KDP columns to evaluate their utility in diagnosing temporal variability in lightning flash characteristics. Specifically, we analyze three severe storms that developed in environments with low-to-moderate instability and strong 0–6-km wind shear in northern Alabama during the 2016–17 VORTEX-Southeast field campaign. In these three cases (a tornadic supercell embedded in stratiform precipitation, a nontornadic supercell, and a supercell embedded within a quasi-linear convective system), we find that the volume of the KDP columns exhibits a stronger correlation with the total flash rate. The higher covariability of the KDP column volume with the total flash rate suggests that the overall electrification and precipitation microphysics were dominated by cold cloud processes. The lower covariability with the ZDR column volume indicates the presence of nonsteady updrafts or a less prominent role of warm rain processes in graupel growth and subsequent electrification. Furthermore, we observe that the majority of cloud-to-ground (CG) lightning strikes a carried negative charge to the ground. In contrast to findings from a tornadic supercell over the Great Plains, lightning flash initiations in the Alabama storms primarily occurred outside the footprint of the ZDR and KDP column objects.

Significance Statement
This study quantifies the correlation between mixed-phase updraft intensity and total lightning flash rate in three severe storms in northern Alabama. In the absence of direct updraft velocity measurements, we use polarimetric signatures, such as ZDR and KDP columns, as proxies for updraft strength. Our analysis of polarimetric radar and lightning mapping array data reveals that the lightning flash rate is more highly correlated with the KDP column volume than with the ZDR column volume in all three storms examined. This contrasts with previous findings in storms over the central Great Plains, where the ZDR column volume showed higher covariability with flash rate. Interestingly, lightning initiation in the Alabama storms mainly occurred outside the ZDR and KDP column areas, contrary to previous findings.
In situ compressive behavior of carbon fibers reinforced PolyEtherEther Ketone laminates exposed to one-sided heat flux
Authors: Vieille Benoit , Coppalle Alexis 
Published: April 2024

This study investigates the influence of a combined thermal heat flux (imposed by a cone calorimeter) and a compressive loading on the deformation and damage mechanisms within quasi-isotropic carbon fibers reinforced PolyEtherEther Ketone laminates. Thermogravimetric Analyses conducted at increasing heating rates under nitrogen (from 5 to 500°C/min) provide valuable information on the thermal decomposition of C/PEEK that ranges from 550°C to 627°C, with a corresponding mass loss ranging from 20 to 26%. From the thermo-mechanical coupling standpoint, the softening and the thermal decomposition of the PEEK matrix under a 50 kW/m2 heat flux result in the micro-buckling of fibers bundles in matrix-rich areas at the ply scale. Ultimately, it leads to the formation and propagation in the transverse direction of plastic kink bands at the laminates scale. Post-failure observations show that this macroscopic kinking propagates specifically according to the PEEK matrix pyrolysis.

Published: April 2024

Objectives Globally, there is a growing number of people who are living with multiple long-term conditions (MLTCs). Due to complex management needs, it is imperative that research consists of participants who may benefit most from interventions. It is well documented that ethnic minority groups and lower socioeconomic status (SES) groups are at an increased risk of developing MLTCs. Therefore, the aim of this systematic review was to determine the level of reporting and representation of underserved groups (ethnic minority and low SES) in intervention studies addressing MLTCs. Design Systematic review. Four databases including Cochrane Library, MEDLINE, CINAHL and Scopus were searched for intervention studies from North America or Europe published between January 1990 and July 2023. Setting Hospital and community-based interventions. We included interventional studies focusing on improving MLTC-related outcomes. Participants Patients with MLTCs. Main outcome measures Total number of studies reporting on ethnicity and SES. Number and proportion of studies reporting by ethnic/SES group. Results Thirteen studies met the inclusion criteria. Only 4 of 13 studies (31%) recorded and reported ethnicity information. Of these four studies that reported on ethnicity, three studies consisted of primarily White participants. Ethnic minority groups were underrepresented, but one study included a majority of African American participants. Moreover, 12 of 13 studies (92%) reported on SES with income and educational level being the primary measures used. SES representation of higher deprivation groups was varied due to limited data. Conclusions For ethnicity, there was a lack of reporting, and ethnic minority groups were underrepresented in intervention studies. For SES, there was a high level of reporting but the proportion of study samples from across the spectrum of SES varied due to the variety of SES measures used. Findings highlight a need to improve the reporting and representation of ethnic minority groups and provide more detailed information for SES through using consistent measures (e.g. education, income and employment) to accurately determine the distribution of SES groups in intervention studies of people with MLTCs.

Published: April 2024

Background: An ageing prison population with complex health needs combined with punitive sentencing practices means palliative care for incarcerated individuals is increasingly important. However, there is limited evidence regarding the models of care delivery in high-income countries, and their associated challenges and benefits. Aim: To develop a typology of models of palliative care provision for incarcerated individuals, synthesise evidence of their outcomes and describe facilitators of and challenges in delivering different models of palliative and end-of-life care in prisons. Design: Scoping review following Arksey and O’Malley, with narrative synthesis. The protocol was registered prospectively (reviewregistry1260). Data sources: MEDLINE, EMBASE, CINAHL, PsycINFO, the Social Sciences Citation Index and grey literature were searched on 15th March 2023. The Mixed Methods Appraisal Tool (MMAT) was used for quality appraisal. Results: A total of 16,865 records were screened; 22 peer-reviewed articles and 18 grey literature sources met the inclusion criteria. Three models were identified: Embedded Hospice, Outsourcing Care and Community Collaboration. The Embedded Hospice model shows potential benefits for patients and prisons. Outsourcing Care may miss opportunities for comprehensive care. Collaborative Care relies on proactive prison-community relationships that could be formalised for improvement. Psychosocial and bereavement needs of those dying in prison and their caregivers lack sufficient documentation. Conclusion: Further research is needed to evaluate prison hospice costs and examine how prison hospices impact compassionate release usage. Beyond the USA, policies might formalise care pathways and recognise best practices. Further investigation to address psychosocial needs of people in prison with life-limiting illnesses and post-death bereavement support is required.
Clinical feasibility of post-contrast accelerated 3D T1-Sampling Perfection with Application-optimized Contrasts using different flip angle Evolutions (SPACE) with iterative denoising for intracranial enhancing lesions: a retrospective study
Authors: Yun Su Young , Heo Young Jin 
Published: April 2024

Background Post-contrast T1-Sampling Perfection with Application-optimized Contrasts using different flip angle Evolutions (SPACE) is the preferred 3D T1 spin-echo sequence for evaluating brain metastases, regardless of the prolonged scan time. Purpose To evaluate the application of accelerated post-contrast T1-SPACE with iterative denoising (ID) for intracranial enhancing lesions in oncologic patients. Material and Methods For evaluation of intracranial lesions, 108 patients underwent standard and accelerated T1-SPACE during the same imaging session. Two neuroradiologists evaluated the overall image quality, artifacts, degree of enhancement, mean contrast-to-noise ratiolesion/parenchyma, and number of enhancing lesions for standard and accelerated T1-SPACE without ID. Results Although there was a significant difference in the overall image quality and mean contrast-to-noise ratiolesion/parenchyma between standard and accelerated T1-SPACE without ID and accelerated SPACE with and without ID, there was no significant difference between standard and accelerated T1-SPACE with ID. Accelerated T1-SPACE showed more artifacts than standard T1-SPACE; however, accelerated T1-SPACE with ID showed significantly fewer artifacts than accelerated T1-SPACE without ID. Accelerated T1-SPACE without ID showed a significantly lower number of enhancing lesions than standard- and accelerated T1-SPACE with ID; however, there was no significant difference between standard and accelerated T1-SPACE with ID, regardless of lesion size. Conclusion Although accelerated T1-SPACE markedly decreased the scan time, it showed lower overall image quality and lesion detectability than the standard T1-SPACE. Application of ID to accelerated T1-SPACE resulted in comparable overall image quality and detection of enhancing lesions in brain parenchyma as standard T1-SPACE. Accelerated T1-SPACE with ID may be a promising replacement for standard T1-SPACE.

Published: April 2024

Introduction: It is widely accepted in plastic surgery that patient positioning can affect the geometry of the nasal tip due to downward gravitational forces. However, empirical data supporting this principle is lacking. The primary objective of this study is to quantify gravitational effects on nasal tip geometry by calculating changes in tip rotation and projection between the supine and upright positions. This analysis will help further assess whether gravity affects the actual positional rotation of the nasal tip or if its impact is solely relative to neighboring landmarks. Methods: This study is a prospective case series that obtains upright and supine nasal measurements in 20 subjects. The nasolabial, nasofrontal, and columellar-facial angles, as well as the Goode, Crumley, Simon, and Powell ratios are used to calculate nasal tip rotation and projection changes. Results: Mean nasolabial angle demonstrated a statistically significant tip derotation of 3.2° in the upright position relative to supine. Mean nasofrontal angle and mean columellar-facial angle did not significantly differ between positions. The nasal tip appeared relatively less projected in the upright position using the Simon and Crumley methods, whereas no significant difference was seen with the Powell and Goode methods. Conclusion: Gravity can influence the apparent nasal tip geometry by altering lip position and length, but it does not impact the true nasal tip geometry when the upper lip is excluded as a reference point.
Exploring the Impact of Length of Residence and Food Insecurity on Weight Status Among Canadian Immigrants
Authors: Chai Lei 
Published: April 2024

Purpose While the individual impacts of long-term residence and food insecurity on overweight/obesity are well-documented, their combined effect on immigrants’ weight status is less understood. This study examines the interaction between length of residence and food insecurity in predicting overweight/obesity among immigrants and investigates whether this relationship is gender-specific. Design A national cross-sectional survey. Setting The 2017-2018 Canadian Community Health Survey. Subjects Immigrants aged 18 and older (N = 13 680). Measures All focal variables were self-reported. Analysis Logistic regression models were employed. Results Long-term immigrants were more likely to report overweight/obesity than their short-term counterparts (OR = 1.39; P < .001). Moreover, immigrants from food-insecure households were at a higher risk of reporting overweight/obesity (OR = 1.27; P < .05) compared to those from food-secure households. The analysis further revealed that food insecurity exacerbated the detrimental association between length of residence and overweight/obesity in men (OR = 2.63; P < .01) but not in women (OR = .66; P > .05). Conclusion The findings suggest that long-term immigrant men may be especially susceptible to the compounded chronic stressors of extended residence and food insecurity. Health professionals and policymakers should advocate for psychosocial resources to help mitigate these adverse effects and support the well-being of immigrant populations.
Awareness and adoption of anti-plagiarism software in India: A case study of ShodhShuddhi
Authors: Singh Varsha , Singh Avinash Kumar 
Published: April 2024

Background Academic writing is essential for researchers to present the research output in a legitimate manner with a precise and clear representation of research data, but few have mastered the art of writing well. Research and researchers are responsible for upholding academic honesty, integrity, and ethics. Needless to say, plagiarism has been around since antiquity, but it has never been as pervasive as it is now. Plagiarism is gradually ingraining itself into our educational system. Pupils are increasingly using the Internet and ICT-based tools to find quick “shortcuts” to the worthwhile but time-consuming task of preparing research papers. Being the third-largest publishing nation, it is the duty of the stakeholders to uphold and work for publication excellence with research ethics and honesty. Since there are so many research articles being published, it is important to understand publishing ethics and anti-plagiarism software in the research domain. If authors are taking ideas from previously published documents or other authors’ works, it is important to ensure acknowledgment and credit in terms of citations, bibliographical references, providing in-text citations, footnotes, and quoting them in any standard citation style. Plagiarism can also be defined as the paraphrasing and text recycling of documents. The challenges in research, which compromise ethics, are also from different stages of research, which include fabrication and falsification of data, AI-based text-generating tools, test recycling, ghostwriting, image plagiarism, audio-to-text-converting tools, etc. A one-stop solution to address all these issues on a single platform is not feasible as it involves multi-level checks and proper policy blended to be implemented at many levels. Objectivity In this paper, analysis and study examine the national awareness of anti-plagiarism software. The primary objectives of the study are to raise awareness and investigate the current state and status of the use of anti-plagiarism software in Bharat (PDS). Methodology The data was collected through the portals and websites of ShodhShuddhi, Shodhganga, and the INFLIBNET Centre. Initiated with 200 universities in the year 2015, about 1086 higher education institutions (HEIs) are provided with PDS under ShodhShuddhi, out of which 894 institutions are active in using software for checking similarities. Three years of usage by active institutions are taken for analysis and study by 1.3 lakh faculty members and research scholars. The increase in usage, even during COVID time, shows that awareness is created in the nation, and the percentage of similarity in first document submission is also coming down gradually in the nation. Character building in academic matters and innovations are key outcomes that can be achieved by addressing plagiarism to strive for a knowledge-based nation.

Published: April 2024

Objective This study aimed to investigate the role of the programmed cell death protein 1 (PD-1) pathway and T peripheral helper (Tph) cells in the pathogenesis of lupus nephritis using lupus-prone BXSB- Yaa mice. Methods Male BXSB- Yaa mice and age-matched male C57BL/6 mice were used. The expression of PD-1 and its ligands (programmed cell death 1 ligand-1, PD-L1 and programmed cell death 1 ligand-2, PD-L2) and the phenotypes of kidney-derived cells and splenocytes expressing these molecules were analyzed by immunofluorescence and flow cytometry. Results Nephritis spontaneously developed in 16-week-old but not in 8-week-old BXSB- Yaa or C57BL/6 mice. PD-1 was expressed on CD4+ mononuclear cells (MNCs) that infiltrated the glomeruli of 16-week-old BXSB- Yaa mice. The frequency of CD4+PD-1+CXCR5−ICOS+ kidney-derived Tph cells was higher in 16-week-old than in 8-week-old BXSB- Yaa and C57BL/6 mice, whereas the frequency of CD4+PD-1+CXCR5+ICOS+ kidney-derived T follicular helper (Tfh) cells was not significantly different between the mice. PD-L1 was constitutively expressed in the renal tubules. PD-L2 was expressed in the glomeruli of 16-week-old BXSB- Yaa mice. The frequency of PD-L1highCD11c+CD3−CD19- and PD-L2+CD11c+CD3−CD19- kidney-derived MNCs in 16-week-old BXSB- Yaa mice was significantly higher than that of the control mice. The percentage of kidney-derived Tph cells but not Tfh cells was correlated with the urinary protein levels in the nephritic mice. Conclusion The results of this study suggest that kidney-infiltrating PD-1+ Tph cells expanded concomitantly with the upregulation of PD-L1 and PD-L2 in the kidneys and the progression of lupus nephritis.

The Impact of Resistance Exercise Training on Glycemic Control Among Adults with Type 2 Diabetes: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Authors: Wan Yuwen , Su Zhanguo 
Published: April 2024

Background: The prevalence of type 2 diabetes mellitus (T2DM) presents a challenge for health organizations because of its high likelihood of morbidity and mortality. There is an increasing body of evidence exploring the efficacy of resistance training (RT) alone on glycemic control. Objective: To update the effectiveness of RT on glycosylated hemoglobin (HbA1c) and fasting glucose in adults diagnosed with T2DM. Methods: CINAHL (EBSDCO), PubMed, MEDLINE (Ovid), and EMBASE (Ovid) databases were searched from inception to 30 January 2024. Published randomized controlled trials (RCTs) of adult humans with T2DM assessing the impact of RT on HbA1c and fasting glucose compared with control condition were included. Data were pooled by the inverse-variance method and reported as mean differences (MDs) with 95% confidence intervals (CIs). Results: Forty-six RCTs totaling 2130 participants met the inclusion criteria. Meta-analysis demonstrated RT significantly reduced HbA1c (MD -0.50% [95% CI, −0.67, −0.34 %], p < .00,001) and fasting glucose (MD -12.03 mg/dl [95% CI, −19.36, −4.69 mg/dl], p = .001). Subgroup analyses found that exercise training durations, gender, and risk of bias had statistically significant effects on HbA1c levels and fasting glucose concentrations after resistance training. However, meta-regression analyses revealed that variables including year of publication, number of sessions per week, mean sample age, sample size, and study quality scores did not significantly affect the change in either HbA1c or glucose. Conclusion: Our meta-analysis with meta-regression delivers further evidence that RT programs are effective approach in attenuation of HbA1c and fasting glucose in individuals with T2DM.
