Published: April 2022

AbstractInformation technology advances may help in conducting epidemiological studies using web-based surveys. Questionnaire-based headache diagnosis should be validated against the doctor’s diagnosis. This study aimed to develop and validate a web-based diagnostic questionnaire for migraine, probable migraine (PM), and tension-type headache (TTH). We constructed a seven-item questionnaire for diagnosing migraine, PM, and TTH. A web-based survey was conducted among adults aged 20–59 years; migraine, PM, and TTH were diagnosed based on the responses. Validation interview was performed via telephone by a neurologist within 1 month after the web-based interview. Finally, 256 participants completed both web-based survey and validation interview. Of them, 121 (47.3%), 65 (25.4%), 61 (23.8%), and 9 (3.5%) were diagnosed with migraine, PM, TTH, and unclassified headache (UH), respectively in the web-based survey, whereas 119 (46.5%), 60 (23.4%), 74 (28.9%), 2 (0.8%), and 1 (0.4%) were diagnosed with migraine, PM, TTH, UH, and primary stabbing headache, respectively in the validation interview. The best agreement was found in migraine (sensitivity: 92.6%; specificity: 94.8%; kappa coefficient: 0.875), followed by TTH (sensitivity: 78.4%; specificity: 98.4%; kappa coefficient: 0.809). PM showed the least agreement (sensitivity: 85.0%; specificity: 92.9%; kappa coefficient: 0.757). In conclusion, our questionnaire is valid in identifying these headache disorders.

AbstractThe main purpose of the study was to analyze the associations between health-related physical fitness and fasting blood glucose in war veterans. In this cross-sectional study, we recruited 764 men and women aged 45–75 years, who were part of the Homeland War between 1990 and 1995 (33.5% women). Health-related physical fitness included: (1) fat mass and fat-free mass (body composition), (2) push-ups in 30 s (muscular dynamic endurance of upper extremities), (3) sit-ups in 30 s (repetitive upper body strength), (4) chair-stands in 30 s (lower body strength), (5) sit-and-reach test (flexibility) and (6) the 2-min step test (cardiorespiratory function). Laboratory measurement of fasting blood glucose was performed according to standardized procedures in resting seated position after a 12-h overnight fast. Generalized estimating equations with multiple regression models were used to calculate the associations between health-related physical fitness and fasting blood glucose. In men, fasting blood glucose was significantly correlated with fat-free mass (β = − 0.25, p < 0.001), push-ups in 30 s (β = − 0.55, p < 0.001), chair-stands in 30 s (β = − 0.50, p < 0.001), sit-ups in 30 s (r = − 0.45, p < 0.001), the sit-and reach test (r = − 0.46, p < 0.001) and the 2-min step test (r = − 0.19, p < 0.001), while fat mass was positively correlated with fasting blood glucose (β = 0.14, p = 0.004). In women, fasting blood glucose was significantly correlated with fat mass (β = 0.20, p = 0.002), fat-free mass (β = − 0.15, p = 0.014), push-ups in 30 s (β = − 0.49, p < 0.001), chair-stands in 30 s (β = − 0.43, p < 0.001), sit-ups in 30 s (β = − 0.52, p < 0.001), the sit-and reach test (β = − 0.40, p < 0.001) and the 2-min step test (β = − 0.35, p < 0.001). This study shows that fasting blood glucose may be predicted by health-related physical fitness test in war veterans.

Published: April 2022

AbstractMembers of theViolagenus play important roles in traditional Asian herbal medicine. This study investigates the ability ofViola odorataL. extracts to inhibit Na+,K+-ATPase, an essential animal enzyme responsible for membrane potential maintenance. The root extract ofV. odoratastrongly inhibited Na+,K+-ATPase, while leaf and seeds extracts were basically inactive. A UHPLC-QTOF-MS/MS metabolomic approach was used to identify the chemical principle of the root extract’s activity, resulting in the detection of 35,292 features. Candidate active compounds were selected by correlating feature area with inhibitory activity in 14 isolated fractions. This yielded a set of 15 candidate compounds, of which 14 were preliminarily identified as procyanidins. Commercially available procyanidins (B1, B2, B3 and C1) were therefore purchased and their ability to inhibit Na+,K+-ATPase was investigated. Dimeric procyanidins B1, B2 and B3 were found to be inactive, but the trimeric procyanidin C1 strongly inhibited Na+,K+-ATPase with an IC50of 4.5 µM. This newly discovered inhibitor was docked into crystal structures mimicking the Na3E1∼P·ADP and K2E2·Pistates to identify potential interaction sites within Na+,K+-ATPase. Possible binding mechanisms and the principle responsible for the observed root extract activity are discussed.

Published: April 2022

AbstractWe assessed the effects of feeding regimen (ad libitum vs. time-restricted food access) and type of food (normal chow (NC: 12% fat) vs. moderately high calorie diet (mHCD: 31% fat)) on fertility competence of female mice. Mice fed mHCD had higher number of oocytes than mice fed NC. On the other hand, when mice were fed NC under time-restricted access to food (NT), the developmental rate to the blastocyst per number of normally fertilized ova was significantly decreased compared to others. The reactive oxygen species (ROS) level in oocytes increased in time-restricted food access and NC group. Transcriptome analysis of whole ovarian tissues from these mice showed a change in the cholesterol metabolism among the four groups. Time-restricted food access decreased serum LDL cholesterol level in both NC and mHCD groups. Moreover, the number of atretic follicles increased in NT mice compared to ad libitum food access mice. The present study shows that mHCD feeding increases the number of ovulated oocytes and that time-restricted feeding of NC impairs the developmental competence of oocytes after fertilization, probably due to the changes in serum cholesterol levels and an increase in the ROS content in oocytes.

Published: April 2022

AbstractUnderstanding the chemical and physical properties of particles is an important scientific, engineering, and medical issue that is crucial to air quality, human health, and environmental chemistry. Of special interest are aerosol particles floating in the air for both indoor virus transmission and outdoor atmospheric chemistry. The growth of bio- and organic-aerosol particles in the air is intimately correlated with chemical structures and their reactions in the gas phase at aerosol particle surfaces and in-particle phases. However, direct measurements of chemical structures at aerosol particle surfaces in the air are lacking. Here we demonstrate in situ surface-specific vibrational sum frequency scattering (VSFS) to directly identify chemical structures of molecules at aerosol particle surfaces. Furthermore, our setup allows us to simultaneously probe hyper-Raman scattering (HRS) spectra in the particle phase. We examined polarized VSFS spectra of propionic acid at aerosol particle surfaces and in particle bulk. More importantly, the surface adsorption free energy of propionic acid onto aerosol particles was found to be less negative than that at the air/water interface. These results challenge the long-standing hypothesis that molecular behaviors at the air/water interface are the same as those at aerosol particle surfaces. Our approach opens a new avenue in revealing surface compositions and chemical aging in the formation of secondary organic aerosols in the atmosphere as well as chemical analysis of indoor and outdoor viral aerosol particles.
Speech-Language Pathologist Reading Survey: Scope of Practice, Training, Caseloads, and Confidence
Authors: Loveall Susan J. , Pitt Adrienne R. , Rolfe Kimberly G. , Mann Jamie 
Published: April 2022

Purpose:
The purpose of this study was to examine speech-language pathologists' (SLPs) opinions on their scope of practice related to reading, self-reported background training, current caseloads, and confidence in their abilities to define, assess, and provide effective treatment for reading-related difficulties.

Method:

SLPs (
N
= 271) from across the United States completed an online survey assessing their opinions on scope of practice, education and training in reading, and confidence in defining, assessing, and treating reading-related difficulties.

Results:
A majority of respondents agreed that the identification, assessment, prevention, and intervention of reading disabilities are all within the scope of practice of SLPs. However, a majority also reported that literacy instruction is more heavily the responsibility of teachers than SLPs, and approximately half felt similarly regarding prevention, assessment, identification, and intervention of reading disabilities. Many respondents did not feel that their training in reading was adequate and felt that more graduate coursework should be dedicated to literacy. There was a lot of variability in responses when asked how often respondents focus on reading skills with clients, ranging from almost daily to never; however, results indicate that SLPs rarely administer reading assessments. Overall, respondents were more confident in their ability to define versus assess or provide therapy for various reading subskills.

Conclusion:
Despite SLPs agreeing that reading is within their scope of practice and feeling confident in some aspects of reading, graduate programs for speech-language pathology may need to provide greater training in literacy, especially related to reading assessment and diagnosis.

Published: April 2022

AbstractThe development and application of information and communication technology in distribution networks (DNs) brings new and abundant measurement data, and this has inspired many solutions for the monitoring, protection and control application of DNs. Against this background, a novel fault location method based on structure‐preserving state estimation (SPSE) is proposed to enhance the fault location performance of DNs. A SPSE model that reflects the change in the network topology during fault incidents is constructed by combining classical measurement equations with newly introduced topology equations. Then, a unified faulted structure‐preserving topology model that eliminates the influence of uncertain fault location point is presented. According to the calculated measurement residual indices and the equivalent fault current for each state estimation (SE) section, the location of the fault is determined. Considering different fault scenarios in a distribution network, the performance of the proposed method is tested by using MATLAB software. Moreover, the factors of sensor accuracy, the bad data and data missing issues are considered. The test results demonstrate that the method can precisely determine the real location of fault and has good robustness to possible data anomalies.

Published: April 2022

AbstractManual or conventional image processing algorithms are commonly used to detect surface problems on mobile phone screens. However, inefficiency and inflexibility are disadvantages. Although the semantic segmentation method has high adaptability and accuracy, it also has a low defect detection efficiency due to its excessive parameters. In order to increase defect detection efficiency, a novel efficient encoder–decoder architecture termed MB encoder–decoder architecture based on MBConv blocks, and that it reduces the number of parameters used in semantic segmentation methods i presented. In addition, by applying the MB encoder–decoder design to the U‐Net, the efficient U‐Net (EU‐Net) is proposed. It confirms the MB encoder–decoder architecture's superiority. Then, EU‐Net to mobile phone surface defect detection in real industrial scenarios. Experimental results on a dataset show the superiority of the proposed algorithm and it can meet the real‐time requirement of industrial production.
Influence of parasitic coupling on current sharing in paralleled SiC MOSFET devices

Published: April 2022

AbstractThis paper comprehensively investigates the current distribution behaviours of paralleled SiC MOSFET devices under the parasitic coupling between gate and power loops. Three types of connection that are commonly adopted in actual applications, comprising common source connection (CSC), Kelvin source connection (KSC) and hybrid source connection (HSC), are thoroughly discussed. The influence mechanism of mismatch in values for three parasitic inductances on current sharing during different switching periods is studied in theory. Simulations and experiments are also carried out and results are used to validate the theoretical analysis. Parasitic capacitance, common source and quasi common source parasitic inductance couplings are the three main coupling modes between gate loop and power loop in a circuit with paralleled SiC MOSFETs. The current imbalance is mainly due to the variation of gate‐source voltage generated by the mismatch in the parasitic inductances through the three coupling paths. This paper aims to provide an insight into current sharing mechanism of paralleled devices with circuit parasitic mismatches. Influence of every parasitic inductance under each of the three coupling modes is investigated and recommendation made on choice of coupling mode and viable switching speed and current balance tradeoff that can be adopted in a practical system design.
Strategy for demand side management effectiveness assessment via a stochastic risk‐based bidding approach in a multi‐energy microgrid containing combined cooling, heat and power and photovoltaic units

Published: April 2022

AbstractThis paper proposes an efficient risk‐based infrastructure management approach for a multi‐energy microgrid to assess the effectiveness of demand‐side management (DSM) through a stochastic strategy. The studied microgrid consists of photovoltaic and combined cooling, heat and power as the energy generation units and load aggregator with the aim of DSM. Based on this structure, day‐ahead operational scheduling is investigated for the microgrid in different scenarios in both summer and winter seasons. The risk consideration is also performed in the bidding procedure dealing with different scenarios and variable prices and probabilities. In this study, the conditional value at risk index is considered to assess the amount of risk and is also studied from two perspectives. In the first case, the level of risk acceptable to the investor, the load aggregator, is selected, and its impact on the day‐ahead scheduling is examined. In the second case, the effect of different levels of risk‐taking and their importance on the scheduling procedure are examined. The main purpose is to show the shortcomings of the traditional DSM method when load management is done for private companies with a certain level of risk and prepare the ground for future studies to solve them.

Pulsed versus Continuous Tones for Evaluating the Loudness of Tinnitus
Authors: Henry James A. , Meikle Mary B. 
Published: April 2022

AbstractLoudness balance techniques are commonly employed to match the loudness of tinnitus using either pulsed or continuous tones; however, it is not known whether the tone duration affects the observed loudness matches. In this study, hearing thresholds and tinnitus loudness matches were measured in 26 subjects with chronic tinnitus using both pulsed and continuous tones. Subjects' thresholds and loudness matches were determined at 11 frequencies between 0.5 and 10 kHz. No significant differences were found between pulsed versus continuous measures, either for thresholds or for loudness matches. There were, however, nine subjects (34.5% of the group) who showed relatively large differences (≥10 dB) at one or more test frequencies. These "outlier" values did not show systematic trends; some were positive, some negative. In conclusion, studies employing group data appear to be comparable if group sizes are sufficiently large (e.g., ≥ 25 subjects). Studies employing smaller numbers of subjects may, however, be vulnerable to potential positive or negative biases introduced by one or more outliers.

Published: April 2022

Objectives
New types of treatments have emerged, such as non-invasive brain stimulation (NIBS), to treat chronic vestibular dysfunction (VD). Considering that NIBS is a promising approach to reduce VD symptoms, this review was aimed to analyze the effects of NIBS in patients with VD.

Methods
We adhered to the methods described in the Cochrane Handbook for Intervention Reviews. The eligibility criteria were as follows: (a) individuals with vestibulopathy having clinical and neuroimaging; (b) Interventions: non-invasive brain stimulation, this intervention comprised transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS); (c) Control: any comparison or sham; and (d) Outcomes: dizziness and balance. We included randomized controlled trials and non-randomized studies from July 2004 to February 2020. We searched the PubMed, CINAHL, Web of Science, Scopus, Cochrane, and Ovid databases. Two pairs of reviewers independently screened all titles and abstracts. Two authors assessed the risk of bias for each study using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions and used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the certainty of the evidence for each outcome.

Results
We identified 136 studies, and included two studies. Both studies used tDCS application. One study used anodal cerebellar tDCS or sham at 2 mA for 25 min associated with vestibular rehabilitation therapy (VRT), and the other study used anodal tDCS over the left dorsolateral prefrontal cortex (F3) for 25–30 min associated with VRT at home. Both studies showed clinical improvement in the Dizziness Handicap Inventory (DHI), State-Trait Anxiety Inventory (STAI), Activities-Specific Balance Confidence (ABC), and Self-Rating Depression Scale (SDS) scores. Both studies presented higher-quality evidence on the GRADE scale and a low risk of bias.

Conclusions
Based on two studies, anodal tDCS over F3 or the cerebellum associated with VRT improved chronic vestibular symptoms.
Probability density functions of quantum mechanical observable uncertainties
Authors: Zhang Lin , Huang Jinping , Wang Jiamei , Fei Shao-Ming 
Published: April 2022

Abstract
We study the uncertainties of quantum mechanical observables, quantified by the standard deviation (square root of variance) in Haar-distributed random pure states. We derive analytically the probability density functions (PDFs) of the uncertainties of arbitrary qubit observables. Based on these PDFs, the uncertainty regions of the observables are characterized by the support of the PDFs. The state-independent uncertainty relations are then transformed into the optimization problems over uncertainty regions, which opens a new vista for studying state-independent uncertainty relations. Our results may be generalized to multiple observable cases in higher dimensional spaces.

We investigate the in-medium masses of open charm mesons (D(

) in strongly magnetized isospin asymmetric strange hadronic matter using a chiral effective model. In the presence of a magnetic field, the number and scalar densities of charged baryons have contributions from Landau energy levels. The mass modifications of open charm mesons result from their interactions with nucleons, hyperons, and the scalar fields (the non-strange field σ, strange field ζ, and isovector field δ) in the presence of a magnetic field. The mass modifications of the charmonium states result from the modification of gluon condensates in a medium simulated by the variation in the dilaton field (χ) in the chiral effective model. The effects of finite quark masses are also incorporated in the trace of the energy-momentum tensor in quantum chromodynamics to investigate the mass shifts of charmonium states. The in-medium masses of open charm mesons and charmonia are observed to decrease with an increase in baryon density. The charged

,

,

, and

mesons have additional positive mass shifts due to Landau quantization in the presence of a magnetic field. The effects of the strangeness fraction are observed to be more dominant for

mesons compared with D mesons. The mass shifts of charmonia are observed to be larger in hyperonic media compared with nuclear media when the effect of the finite quark mass term is neglected. These medium mass modifications can have observable consequences on the production of the open charm mesons and charmonia in high-energy asymmetric heavy-ion collision experiments.
