Charge ordering in θ-(BEDT-TTF)2RbZn(SCN)4 studied by vibrational spectroscopy

Charge distribution in the insulating phase of θ-(BEDT-TTF) 2 RbZn(SCN) 4 [BEDT-TTF denotes bis(ethyl-enedithiolo)tetrathiafulvalene] is investigated using the polarized Raman and infrared (IR) spectroscopy. Both of the Raman and IR spectra showed a multiple-peaks pattern below metal-insulator transition temperature. We assigned the carbon-double-bond (C=C) stretching-modes based on the isotope shift in the 1 3 C-substituted sample, and performed a factor-group analysis for the polarized IR and Raman spectra. These results proved that charge disproportionation (CD) takes place in the insulating phase, and that the spatial pattern of the charge ordering agrees with the symmetry determined by the x-ray diffraction. The CD ratio was estimated from the frequency of a ring C-C stretching mode that is weakly coupled with electronic excited states. A systematic way to investigate the CD phenomenon based on vibrational spectroscopy is discussed.
Prevalence of migraine in systemic lupus erythematosus: A meta-analysis

Background Systemic lupus erythematosus (SLE) is an autoimmune disorder with a wide range of clinical manifestations, including neurological issues in about 25%–75% of cases. Among the neurological involvement cases, most cases show migraine. However, the prevalence of migraine varied worldwide, and in some studies, a higher incidence of migraine in SLE cases was reported compared to healthy controls. In the present study, we adopted a meta-analysis approach to find out the prevalence of migraine in SLE patients worldwide and investigate whether migraine frequency is more prevalent in SLE patients than controls. Material and methods Various literature databases such as Scopus, PubMed, Science Direct, and Google Scholar were screened for eligible studies. The last search was performed on January 21, 2023. Publication biases were accessed by Egger’s regression analysis and funnel plots. Cochrane Q statistics and I2 values explored the presence or absence of heterogeneity. All statistical analysis of meta-analysis was performed in comprehensive meta-analysis software v3. Results Based on predefined inclusion and exclusion criteria, 17 reports comprising 2901 SLE patients and 575 healthy controls were considered in the present study. The meta-analysis revealed the prevalence of migraine to be 34.8%. Furthermore, migraine was more prevalent in SLE patients than healthy controls (OR: 1.964, p = 0.000, 95% CI = 1.512–2.550). Similar trends were also observed while considering another 10 independent reports those were not disclosed about the migraine diagnosis criteria (number of reports: 27, SLE: 3473, HC: 741, prevalence: 33.5%, SLE vs HC: OR = 2.107, p = 0.000, 95% CI = 1.672–2.655). Subgroup analysis demonstrated that SLE patients from South America had a higher prevalence of migraine (56.2%). Conclusions About one-third of SLE patients experience migraine worldwide. The prevalence of migraine is more frequent in SLE patients than the healthy controls.
Public trust is earned: Historical discrimination, carceral violence, and the COVID‐19 pandemic

Abstract Objective To assess whether knowledge of Tuskegee, the U.S. Immigration and Customs Enforcement (ICE) agency's detainment of children, and satisfaction with the George Floyd death investigation were associated with trust in actors involved in the development and distribution of coronavirus vaccines. Data Sources and Study Setting National survey with a convenience sample of Black (n = 1019) and Hispanic (n = 994) adults between July 1 and 26, 2021. Study Design Observational study using stratified adjusted logistic regression models to measure the association between ratings of the trustworthiness of actors involved in the development and distribution of coronavirus vaccines. Principal Findings Among Black respondents, lower satisfaction with the George Floyd death investigation was associated with lower trustworthiness ratings of pharmaceutical companies (ME: −0.09; CI: −0.15, 0.02), the FDA (ME: −0.07; CI: −0.14, −0.00), the Trump Administration (ME: −0.09; CI: −0.16, −0.02), the Biden Administration (ME: −0.07, CI: −0.10, 0.04), and elected officials (ME: −0.10, CI: −0.18, −0.03). Among Hispanic respondents, lower satisfaction was associated with lower trustworthiness ratings of the Trump Administration (ME: −0.14, CI: −0.22, −0.06) and elected officials (ME: −0.11; CI: −0.19, −0.02). Greater knowledge of ICE's detainment of children and families among Hispanic respondents was associated with lower trustworthiness ratings of state elected officials (ME: −0.09, CI: −0.16, 0.01). Greater knowledge of the US Public Health Service Study of Syphilis in Tuskegee was associated with higher trustworthiness ratings of their usual source of care (ME: 0.09; CI: 0.28, 0.15) among Black respondents (ME: 0.09; CI: 0.01, 0.16). Conclusions Among Black respondents, lower satisfaction with the George Floyd death investigation was associated with lowered levels of trust in pharmaceutical companies, some government officials, and administrators; it was not associated with the erosion of trust in direct sources of health care delivery, information, or regulation. Among Hispanic respondents, greater knowledge of the ICE detainments was associated with lower trustworthiness ratings of elected state officials. Paradoxically, higher knowledge of the Study of Syphilis in Tuskegee was associated with higher trustworthiness ratings in usual sources of care.
Risk factors and associated factors for calcaneal apophysitis (Sever’s disease): a systematic review

Objectives The aim of this review was to identify the potential intrinsic and extrinsic risk factors (RFs), associated factors (AFs) and consequences of developing calcaneal apophysitis (CA). Design Systematic review. Data sources Cochrane Library, Embase, Medline Ovid, PubMed, Web of Science and Evidence, searched from inception to April 2021. Eligibility criteria We included cohort, case–control and cross-sectional studies that were conducted in patients younger than 18 years who were exposed to RFs or who presented with factors associated with developing CA. Studies in languages other than English or Spanish were excluded. Data extraction and synthesis Two reviewers worked independently to evaluate the risk of bias of included studies. The Newcastle–Ottawa Scale (adapted version) was used. Results A total of 736 studies were identified and 11 observational studies fully met the inclusion criteria, including 1265 participants with a mean age of 10.72 years. Four studies identified extrinsic factors, 10 identified intrinsic factors and three identified both. The extrinsic and intrinsic RFs, AFs and consequences of CA include limitation of ankle dorsiflexion, foot alignment, stiffness and mobility of the midfoot, plantar pressures and ground reaction force, body mass index, age, gender, presence of other osteochondroses and practice of sport. The risk of bias varied, being either moderate or low. Conclusions Regarding the factors and consequences associated with CA (Sever’s disease), ankle dorsiflexion limitation is the most frequent intrinsic factor studied, followed by peak plantar pressures and foot malalignment. However, disagreements between the investigators of the included studies were found; in some cases, there is a lack of unanimity between different studies as to which factors are considered to be RFs, AFs and consequences.

LOWER BOUNDS FOR THE HELMHOLTZ FUNCTION

Abstract : A mathematical theorem is established for traces of products of bounded Hermitian and definiteoperators. This theorem is applied to the equilibrium partition function by exploiting an infinite product representation of the exponential function of the sum of two operators. As a result, a set of inequalities is established which yields a set of upper bonds for the partition function. This result is invariant to the particle statistics of the system. A general argument yields the result that the classical Helmholtz free energy function serves as a lower bound to the corresponding quantum result. (Author)
A robust line transect method

SUMMARY Standard line transect estimation is not robust to departures from the assumptions that animals do not move in response to the observer before detection and that all animals on or near the trackline are detected. We propose field methodology and analysis methods for which estimates are robust to the first assumption and do not require the second. The approach is applicable only to surveys in which two observation platforms are available, such that conventional line transect field methods, with effort concentrated close to the observer, are carried out from one, and a wider area is scanned from the second, possibly with low probability of detection. An example is a ship or terrestrial line transect survey together with a helicopter searching a wider area ahead of the observer. In the case of ship surveys, both observation platforms might be on the same vessel; observers might scan with hand-held binoculars or the naked eye on the first platform, and an observer with powerful tripodmounted binoculars, screened from the view of the other observers, might search from the second.
Oral administration of helminth fluid modulates distinct tuft cell and immune‐metabolic cues linked to reduced body fat

Intestinal tuft cells have been shown to induce type 2 immune responses during viable parasite infections, but whether oral supplementation with a parasitic exudate is able to promote type 2 immune responses that have been shown to positively regulate obesogenic metabolic processes is yet unresolved. High‐fat fed mice were gavaged with pseudocoelomic fluid (PCF) derived from the helminth Ascaris suum or saline thrice a week during weeks 5–9, followed by examination of intestinal tuft cell activity, immune, and metabolic parameters. Helminth PCF upregulated expression of distinct genes in small intestinal tuft cells, including genes involved in regulation of RUNX1 and organic cation transporters. Helminth PCF also enhanced levels of innate lymphoid cells in the ileum, and eosinophils in epididymal white adipose tissue (eWAT). Network analyses revealed two distinct immunometabolic cues affected by oral helminth PCF in high‐fat fed mice: one coupling the small intestinal tuft cell responses to the fat‐to‐lean mass ratio and a second coupling eosinophils in eWAT to general regulation of body fat mass. Our findings point to specific mechanisms by which oral supplementation with helminth PCF may translate into systems‐wide effects linking to reduced body and fat mass gain in mice during high‐fat feeding.
Variants of Human Mucin Genes in Clear Cell Renal Cell Carcinoma and their Potential Prognostic and Predictive Values.................35

Introduction: For post-mastectomy patients, radiation treatment with conventional fractionation with a treatment duration of five weeks was the frequently used regimen, whereas hypofractionated regimens are recently used in the adjuvant treatment, which has a shorter treatment time over three weeks. We determined to estimate the treatment outcome by survival analysis between these two fractionation schedules to determine if any difference exists between these two groups. Methods: We retrospectively reviewed the data of 348 breast cancer patients who had received adjuvant radiation treatment to the breast from January 2010 to December 2013. After assessing the eligibility criteria, 317 patients had received post-mastectomy radiation treatment to the chest wall and axilla and followed up till December 2018. The conventional fractionation schedule consisted of 50 Gy in 25 fractions, 2 Gy per fraction over five weeks, whereas the hypofractionated schedule was 42.6 Gy in 16 fractions with 2.66 Gy per fraction, over 3.2 weeks. Survival outcomes using 5- year Overall survival and 5-year Disease-free survival between these two fractionations were estimated and compared between the conventional and hypofractionated radiation treatment. RReessuullttss:: All patients were females with a median age of 50 [IQR 45 to 58] and a median follow-up of 60 months. Of the 317 patients, 194 (61%) received hypofractionated radiation and 123(39%) conventional fractionation. The Kaplan-Meier estimates of the 5-year survival rate were 81% (95% CI = 74.9 to 87.6%) for the hypofractionated group (n = 194) and 87.8% (95% CI = 81.5 to 94.6%) for the conventional fractionation
SPC Procedures for Monitoring Autocorrelated Processes

Abstract The inference about the statistical properties of quality control methodologies is based on the assumptions of normality and independence. In real industrial environments though process data is often correlated or exhibits some serial dependence affecting the efficiency of Statistical Process Control (SPC) methodologies. New technology gives managers the option of using more sophisticated SPC models which more accurately reflect the process being monitored, by relaxing some of the assumptions. The aim of this paper is to present, to apply and to evaluate control charts that are designed to account for autocorrelation.
Implementing school nutrition policy: student and parent perspectives.

PURPOSE We explored parent and student perceptions of barriers and facilitating factors influencing the implementation of school nutrition policies (SNPs). Specifically, we focused on the changes made to the school food environment and the acceptance of those changes. METHODS This paper is a report on the first phase of the qualitative component of a larger five-year evaluation of nutrition policies in Prince Edward Island elementary schools (grades 1 to 6) and consolidated schools (grades 1 to 8). Focus groups were conducted with 41 students from four schools, and in-depth interviews were conducted with 12 parents. Interviews were transcribed and coded; analysis was informed by interpretive description. RESULTS Four themes were identified as barriers to effective implementation: inadequate communication with parents and students about the policy and menu changes, limited school resources and volunteers, role/responsibility conflict concerning the feeding of children, and student food preferences. The main facilitating factor was parental and student support for healthy eating at school. CONCLUSIONS Study results add to the limited body of knowledge about stakeholder perceptions during early implementation of Canadian SNPs. Dietitians can foster communication, engagement, and education of stakeholders, which will increase the likelihood that students and their families will accept SNPs.
A scoping review of current and emerging techniques for evaluation of peripheral nerve health, degeneration, and regeneration: part 1, neurophysiology

Peripheral neuroregeneration research and therapeutic options are expanding exponentially. With this expansion comes an increasing need to reliably evaluate and quantify nerve health. Valid and responsive measures that can serve as biomarkers of the nerve status are essential for both clinical and research purposes for diagnosis, longitudinal follow-up, and monitoring the impact of any intervention. Furthermore, such biomarkers can elucidate regeneration mechanisms and open new avenues for research. Without these measures, clinical decision-making falls short, and research becomes more costly, time-consuming, and sometimes infeasible. As a companion to Part 2, which is focused on non-invasive imaging, Part 1 of this two-part scoping review systematically identifies and critically examines many current and emerging neurophysiological techniques that have the potential to evaluate peripheral nerve health, particularly from the perspective of regenerative therapies and research.
Identification of the Physiological Dimension and SelfConcept among Husbands of Iranian Women with Mastectomy; a Directed Content Analysis.

BACKGROUND Breast cancer, as the most prevalent cancer among females, exerts physical and mental impacts on both patients and their husbands. The present study aimed at investigating various dimensions of self-concept among husbands of Iranian women with mastectomy. METHODS This study was conducted on 23 patients with mastectomy and their husbands and therapists using directed content analysis according to Callista-Roy adaptation model. The participants were interviewed regarding how they coped with cancer through video call, and 'physical dimensions' and 'self-concept' subcategories were identified. Content analysis was done using the Elo and Kyngus approach. RESULTS The results revealed two main themes, namely 'exposure to physical challenges' and 'weakened to strengthened self-concept'. DISCUSSION AND CONCLUSION This research showed the existence of many physical and mental problems of women undergoing mastectomy, and it is recommended to do interventions to reduce these complications.
Burst Frequency Effect of DBD Plasma Actuator on the Control of Separated Flow Over an Airfoil

The flow fields around NACA0015 airfoil, separation over which is controlled by a DBD plasma actuator are simulated by implicit large eddy simulation with compact difference scheme, and the burst frequency effect of DBD plasma actuator on the control of separated flow over the airfoil is discussed. The Reynolds number based on chord length is set to 63,000 and the angle of attack is set to 14 [deg]. The DBD plasma actuator is installed at the 0 % and 5 % chord length from the leading edge, and actuated in burst mode. For the burst mode, the nondimensional burst frequency is set to 1 and 6. Through the present analysis, the two mechanisms of separation control are discussed. The first mechanism enhance the vortex shedding from the separation shear layer and avoid the massive separation from the leading edge on burst mode with nondimensional burst frequency of 1. The second mechanism improves the airfoil performance by suppressing the separation region on the burst mode with nondimensional burst frequency of 6. In addition, it is clarified that the first mechanism is more sensitive to the location of the DBD plasma actuator than the second mechanism and it is associated with large fluctuation of lift.
COMBINING INDEPENDENT COMPONENT ANALYSIS WITH CHAOTIC QUANTIFIERS FOR THE RECOGNITION OF POSITIVE, NEGATIVE AND NEUTRAL EMOTIONS USING EEG SIGNALS

Given the importance of recognizingemotions, the present study attempts to recognize emotions from the EEG signals. The main idea of this study is that the brain has independent sources with different functions. Thus, emotions would be observable in independent brain sources. These sources are obtained by Independent component Analysis (ICA) algorithm from recorded EEG signals. However, considering the ill-posed problem in ICA, the Shannon entropy was used to resolve this problem and sort outthe sources. Moreover, Recurrence Quantification Analysis (RQA) was used to extract chaotic features of each source and then, using a k-nearest neighbor (KNN) Classifier, the chaotic features of the three types of emotional state, i.e., positive, negative and neutral were analyzed, which yielded significant results. The results suggested that the greatest difference was observed in lowentropy sources while high- entropy sources showed no significant changes. Finally, for each emotional state, we established a relation between emotions and sources.
A rule-based instantaneous denoising method for impulsive noise removal in range images

To improve comprehensive performance of denoising range images, A rule-based instantaneous denoising method for impulsive noise removal (RID-INR) is proposed in this paper. Based on silhouette features analysis for two typical impulsive noise (IN), dropouts and outliers, a few new coefficients are defined to describe their exclusive features. Founded on several discriminant criteria, the principles of dropout IN detection and outlier IN detection are detailed demonstrated. Subsequently, IN denoising is performed by an Index Distance Weighted Mean filter after a nearest non-IN neighbors searching process. Originated from a theoretical model of invader occlusion, variable window technique is presented for enhancing adaptability of our method, accompanying with practical criteria of adaptive variable window size determination. A complete algorithm has been implemented as embedded modules in two self-developed software. A series of experiments on real range images of single scan line are carried out with comprehensive evaluations in terms of computational complexity, time expenditure and denoising quality. It is indicated that the proposed method can not only detect the impulsive noises with high accuracy, but also denoise them with outstanding efficiency, quality, and adaptability. The proposed method is inherently invariant to translation and rotation transformations, since all the coefficients are established based on distances between the points or their ratio. Therefore, RID-INR is qualified for industrial applications with stringent requirements due to its practicality.
GC–MS analysis of eight aminoindanes using three derivatization reagents

Aminoindanes are a class of novel psychoactive substances (NPSs) that have become more prevalent over the past decade. GC–MS is often utilized for identifying seized drugs and is well regarded for its ability to separate mixtures. However, certain aminoindanes have similar mass spectral data and require specific gas chromatographic stationary phases for separation. Derivatization is an alternative method that can be applied to GC–MS to enhance chromatographic results, providing more selective analysis in seized‐drug identification. This study investigates derivatization techniques to provide options for forensic science laboratories in accurately identifying aminoindanes. Three derivatization reagents, N‐methyl‐bis(trifluoroacetamide) (MBTFA), heptafluorobutyric anhydride (HFBA), and ethyl chloroformate (ECF) were evaluated for the analysis of eight aminoindanes by GC–MS using two common gas chromatographic stationary phases, Rxi®‐5Sil MS and Rxi®‐1Sil MS. All three derivatization methods successfully isolated eight aminoindanes, including the isomers 4,5‐methylenedioxy‐2‐aminoindane (4,5‐MDAI), and 5,6‐methylenedioxy‐2‐aminoindane (5,6‐MDAI) that could not be differentiated prior to derivatization. Reduced peak tailing and increased abundance were observed after derivatization for all the compounds, and mass spectra of the derivatives contained individualizing fragment ions that allowed for further characterization of the aminoindanes. This excluded 4,5‐MDAI and 5,6‐MDAI as they shared the same characteristic ions and were only distinguishable by their retention times. All three derivatization techniques used in this study allow for successful characterization of the aminoindanes and give forensic science laboratories flexibility in their analysis approach when they encounter these compounds.
Active contour models: overview, implementation and applications

A brief overview of deformable contour models, called snakes, is presented. These energy-minimizing curves are constrained by internal continuity forces (tension and bending) and guided by external image forces toward features. Such a tool can be used in areas such as edge detection, motion tracking, and stereo matching and more generally to solve problems of matching a deformable model to an image by means of energy minimization. The convergence speed has been improved by using parametric B-spline approximations of the curves; the model is called B-snakes. As this approximation can control the degree of continuity at the joints between adjacent curve segments, the B-snakes can have breakpoints and include corners. B-snakes have been applied to the extraction of building tops from aerial images, once a first estimate is obtained from a traditional stereo process. <<ETX>>
