AbstractIn the past, the emergency responses to disasters such as fire outbreak accidents, accidents that require first aid were slow and not optimal. With human intellect, it was impractical to analyze vast amounts of data regarding the continuity of the numerous environmental changes and the correlation there may be with emergency responses based on past experiences with similar situations. Today, artificial intelligence is presented as a powerful tool to various organizations. Many have already made various attempts to apply this technology as an advisor for emergency response. This research expands on the practicality and effectiveness of utilizing AI as an advisory platform for disaster response based on the big‐data, and also it designs an AI advisor platform for disaster response with big data‐based algorithms. Finally AI advisor function are defined as part of the AI advisor platform, the voice recognition function, natural language processing function, big data coordination function.

Published: February 2021

AbstractFluorinated peptidomimetic foldamers are still in their infancy. We report here the easy access to fluorinated triazolamers based on 2‐amino‐3,3,3‐trifluoropropyl‐1,4‐triazolyl acetic acid (CF3−1,4‐Tz) and on aminomethyl‐1,4‐triazolyl‐difluoroacetic acid (1,4‐Tz−CF2). Both CF3−1,4‐Tz and 1,4‐Tz−CF2 amino acids were efficiently prepared by copper(I)‐catalyzed Huisgen 1,3‐dipolar cycloaddition. Their conformational preferences were studied by 2D NMR analyses and molecular dynamic simulations. Foldamers based on CF3−1,4‐Tz amino acids are capable of adopting short multi‐stranded β‐sheet‐like structures that are maintained by electrostatic interactions between the triazole proton and N2 atom of neighboring subunits. On the contrary, foldamers based on 1,4‐Tz−CF2 units adopt elongated β‐strand‐like structures, stabilized by electrostatic interaction between fluorine atoms and their neighboring protons.

Published: February 2021

AbstractThe Recovery Assessment Scale‐Domains and Stages (RAS‐DS) is a 38‐item self‐report instrument measuring recovery from serious mental illness. We explored the suitability of the RAS‐DS for individuals with anxiety disorders. A parsimonious short form of the scale was developed. Participants with anxiety disorder symptoms (N = 295) completed the RAS‐DS, DASS‐21 and GAD‐7. Confirmatory factor analysis supported the expected four‐factor structure. Associations with related scales exhibited the expected pattern supporting construct validity in this population. The Recovery Assessment Scale‐Short Form (RAS‐SF) was derived by inspection of factor loadings and modification indices, yielding a 20‐item scale with five items per subscale. Strong correlations between subscales confirmed the total score represented a valid overarching measure of recovery. The present study indicates that recovery is pertinent to individuals with anxiety disorders. Development of the short‐form RAS‐SF affords opportunity for routine measurement of recovery in populations with anxiety and other high prevalence conditions.

Published: February 2021

AbstractAll‐inorganic CsPbBr3 perovskite solar cells (PSCs) have attracted tremendous attention, owing to their excellent stability and rising power conversion efficiency. However, the mechanical flexibility of these solar cells has ground to a standstill because of the high‐temperature requirement for ideal CsPbBr3 perovskite films. In this study, a flexible CsPbBr3 PSC with an efficiency of 5.71 % has been made by means of fabricating a heat‐resistant conductive muscovite substrate, which demonstrates very high mechanical flexibility with nearly unchanged resistance even after 4000 bending cycles (12000 cycles of concave and convex bending for PSCs), owing to the weak van der Waals force and layered structure. Implementation of the muscovite substrate enables the fabrication of flexible PSCs under high‐temperature conditions, providing a new path to increase the efficiency without lowering the crystallization temperature of state‐of‐the‐art electron‐transporting materials and perovskite films in the future.

Authors: Cao Xiaozhou , Wang Song , Xue Xiangxin 
Published: February 2021

AbstractCompared with conventional aqueous and ionic liquid electrolytes, deep eutectic solvent (DES) are considered as electrolyte for redox flow batteries because they have a wider electrochemical window and relatively low price. In this study, CeIV/CeIII and ZnII/Zn redox couples are used as the positive and negative active materials, respectively, in an electrolyte consisting of choline chloride ethylene glycol (ethaline). The structure of CeIII in the positive electrolyte is inferred through spectrum detection. CeIV/CeIII and ZnII/Zn redox couples show a stable potential difference of 2.2 V (vs. Ag) through cyclic voltammetry. The charge and discharge performance of battery was tested at different current densities. In addition, battery performance was evaluated at different temperatures and concentrations of cerium in the electrolyte. Consequently, at a current density of 0.5 mA cm−2 at room temperature and using 1.0 m CeIII, the battery performance reaches the best coulombic efficiency of 84 %.

AbstractIncreasing the energy density of electrochemical double layer capacitors (EDLCs) can broaden their applications in energy storage but remains a formidable challenge. Herein, micropore‐rich yolk‐shell structured N‐doped carbon spheres (YSNCSs) were constructed by a one‐pot surfactant‐free self‐assembly method in aqueous solution. The resultant YSNCSs after activation possessed an ultrahigh surface area of 2536 m2 g−1, among which 80 % was contributed from micropores. When applied in EDLCs, the activated YSNCSs demonstrated an unprecedentedly high capacitance (270 F g−1at 1 A g−1) in 1‐ethyl‐3‐methylimidazolium tetrafluoroborate ([EMIM][BF4]) ionic liquid, affording an ultrahigh energy density (133 Wh kg−1at 943 W kg−1). The present contribution provides insight into engineering porous carbons for capacitive energy storage.

Authors: Dubey Alok Kumar , Mishra Jyoti Prakash , Kumar Amritesh 
Published: February 2021

SummarySynchronizing methodology for shunt active power filter (SAPF) based on the resonant controller using generalized integrator (GI) in the stationary reference frame is of great interest for researchers now a day. In this paper, a phase synchronizing technique based on the complex coefficient filter (CCF) embedded with a frequency locked loop (FLL) is proposed for the fundamental active and reactive component extraction of load current and unit template generation from grid supply. The proposed CCF‐FLL–based control works effectively under varying grid frequency, distorted and unbalance grid voltage conditions to generate the reference source current at a unity power factor for proper harmonic compensation using an indirect current control method. In this work, a detailed mathematical modeling for development of control logic for CCF‐FLL is done, and its feasibility with the bode plot is also confirmed. Simulation for SAPF is performed using both CCF and CCF‐FLL–based control strategy separately to judge the performance of each. Simulation confirms that the proposed CCF‐FLL based control is capable of maintaining the source current with low total harmonic distortion (THD) as per the IEEE‐519 standard with the nonlinear load. The effectiveness of the proposed controller for desired harmonics compensation is also validated through real‐time simulation using OPAL‐RT OP4510 platform.

Published: February 2021

AbstractThe solar power generation system is being increasingly connected to the low power distribution system due to its low cost and abundant availability. The interconnection of the solar power generation system demands new and efficient power converters to provide sufficient boost factor for the solar panel output voltage. This paper presents a Modified Coupled Inductor, Capacitor Multiplier (MCICM) direct current (DC)–DC boost converter to provide high boost factor for the solar panel output voltage and to maximize the benefits of the grid‐interfacing three‐phase three‐wire inverter. The fuzzy logic‐based DC‐link voltage controller and hysteresis current controller (HCC) are also proposed to enhance the power transfer ability of the small power grid‐connected inverter. The new topology of boost converter constructed with the coupled inductors, capacitor, and high‐frequency transformers is demonstrated through the series of tests carried out with extensive MATLAB/Simulink simulation studies. The SPARTAN 3 field‐programmable gate array (FPGA)‐based prototyping model validated the performance of the proposed topology, experimentally.
Lamarckian learning‐based whale optimization algorithm to localize non‐line‐of‐sight nodes for achieving reliable data dissemination in vehicular ad‐hoc networks
Authors: Balamurugan A. 
Published: February 2021

SummaryNon‐line‐of‐sight (NLOS) nodes in vehicular ad‐hoc networks (VANETs) are responsible for introducing channel congestion and broadcast storm during data dissemination for sustaining reliable connectivity between vehicular nodes. In this paper, an Integrated Lamarckian Learning and Whale Optimization Algorithm‐based NLOS Localization Technique (ILL‐WOA‐NLOS‐LT) is proposed for NLOS localization in order to improve high reliability and low latency during the emergency message sharing. This proposed ILL‐WOA‐NLOS scheme inherits an optimization process that concentrates on the objective of minimizing latency during warning message delivery. It included the merits of Lamarckian evolution‐based learning strategy for strengthening and speeding up the rate of local search. It possesses maximum probability of acquiring higher adaptability through active learning for improving the global convergence speed to attain better localization of NLOS nodes in emergency situations. It also incorporated a better tradeoff between exploitation and exploration for effective NLOS localization with reduced error. The simulation experiments of the proposed ILL‐WOA‐NLOS scheme conducted through EstiNet 8.1 confirmed its predominance in achieving an excellent mean emergency message dissemination rate of 12.96% mean NLOS node localization rate of 14.21% and the mean neighborhood awareness rate of 13.62% with different number of vehicular nodes, compared to the benchmarked localization approaches considered for investigation. The localization error of the proposed ILL‐WOA‐NLOS scheme was also identified to be significantly reduced by 12.82% compared to the baseline schemes used for investigation.

AbstractBackgroundHuman papillomavirus (HPV) is a primary risk factor for cervical cancer. HPV 16 and 18 are the two most carcinogenic genotypes and have been reported in the majority of cervical cancer. High‐risk HPVs (hrHPVs) other than HPV 16/18 cause approximately a quarter of cervical cancers. We aimed to present the colposcopy‐guided biopsy results of non‐16/18 hrHPV‐infected women with negative cytology.MethodsThis is a retrospective cohort study conducted on 752 patients between the ages of 30‐65 years with non‐16/18 hrHPV and negative cytology undergoing colposcopy‐guided biopsy at a tertiary gynecological cancer center between January‐2016 and January‐2019.ResultsThe mean age of the women was 42.35±9.41 years. Cervical intraepithelial neoplasia (CIN) 2+ lesion was detected in 49 (6.5%) women with negative cytology. The rate of CIN 2+ lesions in women with abnormal cytology was 12.8%. Patients with abnormal cytology had about 2.1 and 2.4 times increased the odds of CIN 2+ lesion in cervical biopsy and endocervical curettage specimens, respectively. CIN 3+ lesion was detected in 20 (2.7%) women with negative cytology. One (0.1%) of the patients with HPV 39 and negative cytology had invasive cervical cancer. The two most common HPV subtypes were HPV 31 and HPV 51.ConclusionsThe risk of cervical preinvasive lesions still can be detected and cannot be completely eliminated among hrHPV other than 16/18‐infected women with negative cytology. Based on the results of this study, referral of non‐16/18 hrHPV‐infected women with negative cytology to colposcopy is supported as a credible and feasible strategy.
Neuroprotective effect of Na+/H+ exchangers isoform‐1 inactivation against 6‐hydroxydopamine‐induced mitochondrial dysfunction and neuronal apoptosis in Parkinson's disease models

AbstractParkinson's disease (PD) is a disabling neurodegenerative disease mainly caused by degeneration of mesencephalic dopaminergic neurons in the substantia nigra pars compacta (SNpc). The neuroprotective role of Na+/H+ exchangers isoform‐1 (NHE1) inactivation in cerebral ischemic damage has been elucidated. The current study aimed to investigate the impacts of NHE1 in PD. In this study, 6‐hydroxydopamine (6‐OHDA)‐induced PD rat models were established to attempt to illuminate the role and underlying mechanisms of NHE1 in SNpc neurons of PD. Meanwhile, nerve growth factor‐stimulated PC12 cells followed by 6‐OHDA treatment was used to mimic PD in vitro. Results showed that the protein levels of NHE1 were significantly increased in the SNpc neurons of rats and differentiated PC12 cells after 6‐OHDA treatment. Inactivation of NHE1 with chemical inhibitor HOE642 suppressed SNpc neuronal loss and NHE1 expression in PD rats. The overlays of tyrosine hydroxylase and NHE1 displayed that NHE1 expression was not colocalized but closely associated with TH. Besides, treatment with HOE642 relieved the dyskinesia, mitochondrial dysfunction, and neuronal apoptosis. Further in vitro evidence confirmed that inhibition of NHE1 by genetic‐knockdown prevented mitochondrial dysfunction and apoptosis. Our study represents the first experimental evidence of a potential role for NHE1 in the pathogenesis of PD.
Can effective population size estimates be used to monitor population trends of woodland bats? A case study of Myotis bechsteinii
Authors: Wright Patrick G. R. , Schofield Henry , Mathews Fiona 
Published: February 2021

AbstractMolecular approaches to calculate effective population size estimates (Ne) are increasingly used as an alternative to long‐term demographic monitoring of wildlife populations. However, the complex ecology of most long‐lived species and the consequent uncertainties in model assumptions means that effective population size estimates are often imprecise. Although methods exist to incorporate age structure into Ne estimations for long‐lived species with overlapping generations, they are rarely used owing to the lack of relevant information for most wild populations. Here, we performed a case study on an elusive woodland bat, Myotis bechsteinii, to compare the use of the parentage assignment Ne estimator (EPA) with the more commonly used linkage disequilibrium (LD) Ne estimator in detecting long‐term population trends, and assessed the impacts of deploying different overall sample sizes. We used genotypic data from a previously published study, and simulated 48 contrasting demographic scenarios over 150 years using the life history characteristics of this species The LD method strongly outperformed the EPA method. As expected, smaller sample sizes resulted in a reduced ability to detect population trends. Nevertheless, even the smallest sample size tested (n = 30) could detect important changes (60%–80% decline) with the LD method. These results demonstrate that genetic approaches can be an effective way to monitor long‐lived species, such as bats, provided that they are undertaken over multiple decades.
An isolated white‐tailed deer (Odocoileus virginianus) population on St. John, US Virgin Islands shows low inbreeding and comparable heterozygosity to other larger populations

Published: February 2021

AbstractThis is the first study to document the genetic diversity of the white‐tailed deer population on St. John, US Virgin Islands. The island population was founded by a small number of animals, has very limited hunting or predation, and recently experienced a reduction in size following an extended drought in 2015. DNA samples were collected from hair from 23 anesthetized adult deer (13 males, 10 females) ranging in age from 1 to 8 years (3.36 ± 1.9 years) and also from fecal DNA samples, for a total of 42 individuals analyzed for genetic diversity. The St. John deer data set averaged 4.19 alleles per marker and demonstrates the second lowest number of alleles (A) when compared to other populations of Odocoileus virginianus (4.19). Heterozygosity was similar to the other studies (0.54) with little evidence of inbreeding. To explain the level of heterozygosity and level of inbreeding within the St. John population, three hypotheses are proposed, including the effect of intrinsic biological traits within the population, a recent infusion of highly heterogeneous loci from North American populations, and a consistent level of immigration from a nearby island. Additional work is needed to further understand the genetic history of the St. John and regional deer populations.

AbstractObjectiveTo study the impact of secondary mental disorders in patients affected with acromegaly and correlate them with quality of life (QoL) and disease status.DesignAn observational transversal descriptive and comparative study that evaluates QoL's impact due to secondary mental disorders in affected Mexicans with acromegaly using AcroQoL and SF‐36 instruments. Correlation of the results with the disease's biochemical status was performed. According to Beck's scales, anxiety and depression analyses evaluate QoL's impact, and its gender variability is described.ResultsEighty‐five patients with diagnoses of acromegaly were included. The mean age was 43.18 years, 47 being women (55.29%). The mean age at diagnosis was 37.95 years, with no difference between men and women. AcroQoL and SF‐36 global and sub‐domain scores differed significantly between men and women, the latter having lower global and individual sub‐domain scores. The mean score of QoL, according to AcroQoL, is 59.40. In women, the mean values are less (55.13) than men (64.68), p = 0.021. The sub‐domain analyses’ scores in physical, appearance and social relationships were less in women (53.21; 47.34; 62.32) than men (62.68; 56.76; 73.87) p = 0.044, 0.069 and 0.013, respectively. Higher Beck's Depression Inventory (BDI) and Beck's Anxiety Inventory (BAI) scores correlated with lower QoL as assessed by global and individual sub‐domain scores. Women presented significantly higher BDI and BAI mean scores when compared to men regardless of their biochemical status. Anxiety (p = 0.027) and depression (p < 0.001) severity were higher in women compared to men.ConclusionCorrelations between female gender, depression/anxiety scores and QoL require further validation. There is much to be routinely done to improve secondary psychopathology in patients affected by this disease. The need for mental status screening at diagnosis should be emphasized to identify secondary mental illnesses to improve QoL with its treatment.

AbstractAimsPatients with adult congenital heart disease (ACHD) carry an increased risk for sudden cardiac death. Implantable cardioverter‐defibrillator (ICD) therapy may be challenging in these patients due to anatomical barriers, repeated cardiac surgery, or complicated transvenous access. Thus, the subcutaneous ICD (S‐ICD) can be a promising alternative in this patient population. Patients with ACHD show significant electrocardiogram (ECG) abnormalities, which could affect S‐ICD sensing because it depends on surface ECG.Methods and resultsOne hundred patients with ACHD were screened for S‐ICD eligibility. Standard ECG‐based screening test and automated S‐ICD screening test were performed in all patients. Sixty‐six patients (66%) were male. Underlying congenital heart disease (CHD) was mainly CHD of great complexity (71%) and moderate complexity (29%), including repaired tetralogy of Fallot (20%), which was the most common entity. Thirty‐seven patients (37%) already had a pacemaker (23%) or ICD (14%) implanted. Automated screening test identified 83 patients (83%) eligible for S‐ICD implantation in either left parasternal position (78%) or right parasternal position (75%). Absence of sinus rhythm, QRS duration, and a paced QRS complex were associated with S‐ICD screening failure in univariate analysis. Receiver operating characteristic curve and multivariate analysis revealed a QRS duration ≥148 ms as the only independent predictor for S‐ICD screening failure.ConclusionsPatients with ACHD show satisfactory eligibility rates (83%) for S‐ICD implantation utilizing the automated screening test, including patients with CHD of high complexity. S‐ICD therapy should be considered with caution in ACHD patients with a QRS duration ≥148 ms and/or need for ventricular pacing.
