A wireless power transfer system based on quasi‐parity–time symmetry with gain–loss ratio modulation
Authors: Li Jianguo , Zhang Bo 
Published: November 2022

SummaryWireless power transfer (WPT) systems based on parity–time (PT) symmetry can realize robust power transfer against the fluctuation of distance. There is an exceptional point (EP) that partitions the PT‐symmetric and PT‐broken phase, and it is nonadjustable at the conventional system with unity gain–loss ratio unless changing circuit parameters, which limits the improvement of its transfer performance. This paper proposed a novel quasi‐PT‐WPT system based on gain–loss ratio modulation. The proposed system can operate under different gain–loss condition with constant transfer power and efficiency regardless of coupling coefficient variation at the PT‐symmetric phase, which can enhance either the maximum transfer efficiency or distance alternatively. The proposed system consists of a nonlinear gain with adjustable gain–loss ratio to enable the transfer performance control, which is implemented by the virtual impedance. Experimental results verified the correctness of the theoretic analysis and implied the inherent contradiction between the transfer efficiency and distance.
The role of emotion regulation in the relationship between mindfulness and risk factors for disordered eating: A longitudinal mediation analysis

Published: November 2022

AbstractObjectiveEvidence suggests mindfulness may reduce risk factors for disordered eating. However, mechanisms of change in this relationship are unclear. This longitudinal study tested whether emotion regulation mediates the prospective associations between mindfulness and two proximal risk factors for disordered eating: weight and shape concerns, and negative affect.MethodThis study is a secondary analysis of data collected within an eating disorder prevention trial. Adolescent girls (N = 374, Mage = 15.70, SD = 0.77) completed self‐report measures of mindfulness, emotion regulation, weight and shape concerns, and negative affect at baseline, 2 months following baseline, and 7 months following baseline. Path analyses were computed to test hypothesized indirect effects using confidence intervals based on 5000 bootstrap samples.ResultsHigher baseline mindfulness predicted lower weight and shape concerns and negative affect at 7 months via a mediator of better emotion regulation at 2 months. This effect remained while controlling for earlier measurements of the mediator and outcome in the model of negative affect but not weight and shape concerns.DiscussionEmotion regulation may be an important mechanism explaining how mindfulness influences negative affect. Efforts should be made to intervene on mindfulness and emotion regulation in prevention and early intervention programmes for eating disorders and other psychiatric conditions.Public SignificanceResearch has shown that mindfulness can help to reduce some of the risk of developing an eating disorder. This study explored whether mindfulness reduces some of this risk by helping people to better manage their emotions. Understanding this process can help us to develop better mindfulness‐based strategies to support people who are at risk of developing an eating disorder.

Published: November 2022

AbstractBackground and ObjectiveNeuropathic pain is an occasionally reported complication of coronavirus disease 2019 (COVID‐19) that has received increased attention in scientific literature. In this systematic review and meta‐analysis, we aimed to provide information on the frequency of neuropathic pain associated with COVID‐19.Databases and Data TreatmentWe systematically reviewed and analysed literature regarding neuropathic pain associated with COVID‐19. Literature searches were conducted in PubMed, EMBASE and Cochrane Library databases. We considered prospective and retrospective studies published up until September 2022 (limitations included English language, full‐text publications and studies including at least 10 patients). A random effects meta‐analysis was performed and heterogeneity and publication bias were assessed.ResultsWe identified 149 studies. We included 17 studies in the systematic review, and six studies reporting the frequency of neuropathic pain in the acute/subacute phase of COVID‐19 in the meta‐analysis. The estimated frequency of neuropathic pain ranged between 0.4 and 25%. Forest plot analysis showed that the random effect overall frequency was 10% (95% confidence interval: 5%–15%), with a high level of heterogeneity (Chi2 = 104; Tau2 = 0.004; df = 5; I2 = 95%; test for overall effect: Z = 3.584; p < 0.0005). The overall risk of bias was moderate in all studies selected, particularly due to the poor description of neuropathic pain diagnostic criteria.ConclusionsThe pooled estimated frequency of neuropathic pain associated with COVID‐19 should be considered with caution due to the high heterogeneity across studies and the poor description of the neuropathic pain diagnostic criteria applied.SignificanceEmerging evidence supports the development of neuropathic pain as a complication of COVID‐19. However, longitudinal studies enrolling consecutive patients with COVID‐19 that detail the diagnostic criteria for neuropathic pain are needed to better assess the frequency of this condition.
RETRACTED: Activation‐based recurrent learning method for wearable sensor data processing in human activity recognition

Published: November 2022

AbstractHuman activity recognition using wearable sensors is a universal application for providing additional real‐time support in AAL and medical healthcare systems. Input signals and sensor data are analyzed for the features, followed by correlation analysis to achieve better recognition accuracy. In this article, activation‐based recurrent learning for human activity detection is introduced. This method is based on recurrent neural networks that pre‐classifies the features and extract them for time and rate based on the input signals. Following the pre‐classification, the repetitive learning estimates the features for the correlation and activities to reduce false‐negative errors in processing. This recurrent process is validated using a conditional activation function and rectified linear unit for joint and concurrent layer processing. The combined processing feature of this proposed method helps to improve the accuracy by 92% and recall by 94.5% by reducing the computation time. The performance of the proposed method is analyzed for six activities, varying iterates, and at time intervals.

AbstractSeveral studies have reported the value of neutrophil‐to‐lymphocyte ratio (NLR) for the prognosis of hypopharyngeal cancer. However, contradictory findings have also been published. We aimed to clarify the effect of NLR on the prognosis of hypopharyngeal cancer through meta‐analysis. Systematic search of PubMed and other database with study selection and data extraction. The combined hazard ratio (HR) and 95% confidence intervals (CI) were calculated using STATA, applying either a fixed‐effects or random‐effects model. Meta‐regression, subgroup analysis, and sensitivity analysis were used to analyze sources of heterogeneity. Publication bias were also assessed. This meta‐analysis included 2232 patients with hypopharyngeal cancer from seven studies. The combined HR (OS, HR = 1.80, 95CI%, 1.14–2.82; PFS, HR = 1.88, 95CI%, 1.26–2.79) suggested that high NLR was associated with poor overall survival (OS) and progression‐free survival (PFS). Pretreatment NLR can be used as an effective serological indicator to assess the prognosis of patients with hypopharyngeal cancer.

AbstractBackgroundThere have been a number of reports suggesting that LDL apheresis, including LDL adsorption and double filtration plasmapheresis (DFPP), can be applied for the treatment of lower extremity peripheral arterial disease (PAD) in hemodialysis patients, whereas there is no definitive recommendation for the use of LDL apheresis.Study DesignThe change of skin perfusion pressure (SPP) during LDL apheresis was measured in every single treatment to determine the effect of LDL adsorption and DFPP on improving blood flow in lower extremity PAD hemodialysis patients. Eleven hemodialysis patients treated with more than two series of LDL apheresis were involved in the study. “One series” included 10 treatments of LDL apheresis according to the Japanese health care insurance system.ResultsIn total, 320 treatments (32 series) of LDL apheresis were performed utilizing either LDL adsorption or DFPP treatment in 11 patients. The SPP values pre‐ and post‐apheresis were recorded in 315 treatments (228 LDL adsorption and 87 DFPP). The SPP was significantly improved after both LDL adsorption (P < .001) and DFPP (P = .002) treatment. The median change of SPP was significantly larger in the LDL adsorption group (12.6 mm Hg, range: −48.5, 77.0 mm Hg) than in the DFPP group (6.7 mm Hg, range: −42.0, 72.5 mm Hg) (P = .003). The LDL adsorption consistently offered a significant increase in the SPP, whereas DFPP treatment seemed to have modest effects on the improvement of SPP compared to the LDL adsorption.ConclusionsThese data indicate that LDL adsorption should be considered the primary LDL apheresis therapy for lower extremity PAD in hemodialysis patients to achieve improvement of blood flow.

AbstractBackground and AimThis study aimed to assess the antioxidant effects of amlodipine in transfusion‐dependent β‐thalassemia (TDT) patients.MethodsThis crossover trial consisted of two sequences (AP and PA). In the AP sequence, nine cases received amlodipine 5 mg daily (phase I) and then were switched to placebo (phase II). In PA sequence, 10 patients took the placebo (phase I) and were shifted to amlodipine (phase II). The washout period was 2 weeks. The length of each phase was 6 months. Serum malondialdehyde (MDA, μmol/L), carbonyl (protein CO, μM/L), glutathione (GSH, nM/L), and total antioxidant capacity (TAC, μmol FeSO4/L) were measured in the beginning and at the end of phases I and II. The clinical significance was viewed as a minimum change difference of 5% for each outcome between amlodipine and placebo.ResultsSeventeen cases completed the study. According to the baseline MDA values, the adjusted Hedges's g for MDA was −0.59, 95% confidence interval [CI] −1.26 to 0.08. After controlling the baseline protein CO values, Hedges's g computed for protein CO was −0.11, 95% CI −0.76 to 0.55. The estimated values of the adjusted Hedges's g for GSH and TAC were also 0.26, 95% CI −0.40 to 0.91, and 0.42, 95% CI −0.24 to 1.09, respectively. The change difference for MDA was 8.3% (protein CO 2.2%, GSH 3.1%, and TAC 12.9%).ConclusionClinically, amlodipine therapy is an efficacious adjuvant treatment with conventional iron chelators for improving the levels of MDA and TAC in patients with TDT.

AbstractResearch links adolescent dating violence (ADV) victimization to negative developmental outcomes, including involvement in substance use. Informal mentoring is associated with several positive outcomes, including reduced risk of substance use. Addressed in this study is whether support from an informal mentor can function to protect victims of ADV from involvement in substance use. Participants were 152 adolescents (grades 9–12). Findings revealed a significant association between ADV victimization and adolescents' involvement in substance use, as well as some evidence that support from an informal mentor moderates that link. When informal mentor support was low or at the mean, ADV victimization was significantly linked to adolescents' involvement in substance use; when informal mentor support was high, ADV victimization was unrelated to substance use involvement. Discussed are research and practice implications of the potential protective role of informal mentors for victims of ADV.

Published: November 2022

AbstractMitigation measures are needed to prevent large loads of phosphate originating in agriculture from reaching surface waters. Iron‐coated sand (ICS) is a residual product from drinking water production. It has a high phosphate adsorption capacity and can be placed around tile drains, taking no extra space, which increases the farmers’ acceptance. The main concern regarding the use of ICS filters below groundwater level is that limited oxygen supply and high organic matter concentrations may lead to the reduction and dissolution of iron (hydr)oxides present and the release of previously adsorbed phosphate. This study aimed to investigate phosphate adsorption on ICS at the onset of iron reduction. First, we investigated whether simultaneous metal reduction and phosphate adsorption were relevant at two field sites in the Netherlands that use ICS filters around tile drains. Second, the onset of microbially mediated reduction of ICS in drainage water was mimicked in complementary laboratory microcosm experiments by varying the intensity of reduction through controlling the oxygen availability and the concentration of degradable organic matter. After 3 yr, ICS filters in the field removed phosphorus under low redox conditions. Over 45 d, the microbial reduction of manganese and iron oxides did not lead to phosphate release, confirming field observations. Electron microscopy and X‐ray absorption spectroscopy did not evince systematic structural or compositional changes; only under strongly reducing conditions did iron sulfides form in small percentages in the outer layer of the iron coating. Our results suggest that detrimental effects only become relevant after long periods of operation.

AbstractBoth 2‐(N‐arylcarbamoyl)methylsulfanyl‐3‐cyano‐5‐ethoxycarbonyl‐6‐methyl‐4‐(2′‐thienyl)pyridines 2a‐e and their isomers, 3‐amino‐2‐(N‐arylcarbamoyl)‐5‐ethoxy‐carbonyl‐6‐methyl‐4‐(2′‐thienyl)thieno[2,3‐b]pyridines 3a‐e were synthesized by reaction of ethyl 3‐cyano‐1,2‐dihydro‐6‐methyl‐4‐(2′‐thienyl)‐2‐thioxopyridine‐5‐carboxylate (1) with the respective N‐aryl‐2‐chloroacetamides in the presence of different basic catalysts. Compounds 3a‐e were used as precursors for synthesizing of pyridothienopyrimidinones 4a‐e, pyridothienotriazinones 5a‐e and tetrahydropyridothienopyrimidinones 6a‐c via treatment with triethyl orthoformate, nitrous acid, and/or 4‐chlorobenzaldehyde respectively. The photophysical properties of aminothienylthienopyridines 3a‐e and tetrahydropyridothieno‐pyrimidine‐4(3H)‐ones 6a‐c were studied and the fluorescence data revealed that all selected compounds possess AIE behaviors in solution and in solid state. Most of the prepared compounds were evaluated in vitro for their antibacterial and antifungal activities, and considerable results were obtained. Moreover, the cytotoxic activity of thienopyridines 3a‐d against MCF‐7 and HepG2 cell lines was evaluated and they showed moderate to very strong activity.

AbstractThe global monkeypox outbreak in 2022 has severely affected the life and health of people. Currently, partial smallpox vaccines have been approved for monkeypox prevention. Considering the potential occupational health risks of monkeypox infection among healthcare workers (HCWs), this study explored the willingness of Chinese HCWs to receive the monkeypox vaccine and analyzed the factors influencing their decision. We conducted an online cross‐sectional survey among HCWs of 10 Chinese hospitals from May 30th, 2022 to August 1st, 2022. Specifically, a self‐report questionnaire was administered to evaluate the attitude and acceptance of HCWs toward the monkeypox vaccine, followed by a multivariate logistic regression analysis to determine the independent predictors of vaccination. The survey included 1032 participants, of whom 90.12% expressed their willingness for vaccination (vaccine hesitancy rate = 9.88%). Univariate analysis showed that 11 variables differed significantly between the vaccine acceptance and vaccine hesitancy groups. Multivariate logistic regression analysis demonstrated that the age of 30–40 years (odds ratio [OR] = 0.504, 95% confidence interval [CI]: 0.284–0.893, p = 0.019 vs. age of <30 years old), working in a secondary hospital (OR = 0.449, 95% CI: 0.249–0.808, p = 0.019 vs. working in a tertiary hospital), considering vaccination necessary for controlling monkeypox infection (OR = 4.135, 95% CI: 2.109–8.106, p < 0.001 vs. not considering it necessary), willingness to pay for the monkeypox vaccine (OR = 2.125, 95% CI: 1.206–3.745, p = 0.009 vs. no willingness to pay), considering implementation of mandatory vaccination necessary (OR = 1.990, 95% CI: 1.023–3.869, p = 0.043 vs. not considering it necessary), and recommending family members and friends to take the vaccine (OR = 13.847, 95% CI: 7.487–25.609, p < 0.001 vs. not recommending) were crucial independent predictors of the willingness to receive monkeypox‐related vaccination. This study evaluated the acceptance and hesitancy rates of Chinese HCWs toward the monkeypox vaccine and found that the willingness to receive vaccination was mainly correlated to age, hospital level, and attitude toward vaccination. Therefore, to promote vaccine absorption, we recommend expanding publicity, formulating reasonable policies, and improving the recognition of vaccines.

AbstractPublic Health Genomics (PHG) is a relatively new field. The wide application of genomic technologies played a pivotal role in elucidating the full genomic sequence of the SARS‐CoV‐2 virus. This breakthrough proved to be the starting point in the manufacture of diagnostic kits and the subsequent making of vaccines. Beyond the COVID‐19 pandemic, many African countries can take advantage of the various investments in genomic technologies to introduce and intensify the use of genomics for public health gain. Public Health Genomics effectively monitors, prevents, and manages non‐communicable and infectious diseases. However, there are several challenges to implementing PHG in Africa. In this perspective article, we discuss the utilization of PHG during the COVID‐19 pandemic, the lessons learned from using PHG to manage and contain the COVID‐19 pandemic, as well as potential challenges Africa may face when putting PHG into practice compared to challenges of other regions. We also discuss our recommendations for overcoming these challenges.

Published: November 2022

AbstractWe investigated to which degree commercial funding is associated with estimated intervention effects in randomized trials. We included meta‐epidemiological studies with published data on the association between commercial funding and results or conclusions of randomized trials. We searched five databases and other sources. We selected one result per meta‐epidemiological study, preferably unadjusted ratio of odds ratios (ROR), for example, odds ratio(commercial funding)/odds ratio(noncommercial funding). We pooled RORs in random‐effects meta‐analyses (ROR <1 indicated exaggerated intervention effects in commercially funded trials), subgrouped (preplanned) by study aim: commercial funding per se versus risk of commercial funder influence. We included eight meta‐epidemiological studies (264 meta‐analyses, 2725 trials). The summary ROR was 0.95 (95% confidence interval 0.85–1.06). Subgroup analysis revealed a difference (p = 0.02) between studies of commercial funding per se, ROR 1.06 (0.95–1.17) and studies of risk of commercial funder influence, ROR 0.88 (0.79–0.97). In conclusion, we found no statistically significant association between commercial funding and estimated intervention effects when combining studies of commercial funding per se and studies of risk of commercial funder influence. A preplanned subgroup analysis indicated that trials with high risk of commercial funder influence exaggerated intervention effects by 12% (21%–3%), on average. Our results differ from previous theoretical considerations and findings from methodological studies and therefore call for confirmation. We suggest it is prudent to interpret results from commercially funded trials with caution, especially when there is a risk that the funder had direct influence on trial design, conduct, analysis, or reporting.
