Published: April 2022

AbstractIntercalation pseudocapacitance is a faradaic electrochemical phenomenon with high power and energy densities, combining the attractive features of capacitors and batteries, respectively. Intercalation pseudocapacitive responses exhibit surface‐limited kinetics by definition, without restriction from the collective of diffusion‐based processes. The surface‐limited threshold (SLT) corresponds to the maximum voltage sweep rate (vSLT) exhibiting a predominantly surface‐limited current response prior to the onset of diffusion‐limitations. Prior studies showed increased lithium diffusivity for amorphous titania compared to anatase. Going beyond prior binary comparisons, here a continuum of amorphous titania configurations were prepared using a series of calcination temperatures to tailor both amorphous character and content. The corresponding amorphous‐phase vSLT increased monotonically by 317 % with lowered calcination temperatures. Subsequent isomorphic comparisons varying a single transport parameter at a time identified solid‐state lithium diffusion as the dominant diffusive constraint. Thus, performance improvements were linked to increasing the lithium diffusivity of the amorphous phase with decreased calcination temperature. This remarkably enabled 95 % capacity retention (483±17 C/g) with 30 s of delithiation (120 C equivalent). These results highlight how isomorphic sample series can reveal previously unidentified trends by reducing ambiguity and reiterate the potential of amorphization to realize increased performance in known materials.

Authors: Chowdhury Emon Kalyan , Dhar Bablu Kumar , Stasi Alessandro 
Published: April 2022

AbstractThis paper aims to measure the impact of COVID‐19 and changes in economic policy uncertainty (EPU) on the US stock market volatility using Event Study, Stepwise Regression, and Vector Autoregression (VAR) models. The impact has been examined under three contexts namely inside the US, outside the US and the whole world. This study finds negative cumulative abnormal returns of the market in response to the announcement of new cases and death records whereas the market reacts positively to the announcement of the financial bailout. The negative and significant impact of reported deaths and cases on the volatility of stock indices indicates that the US stock market is highly sensitive to the COVID‐19. EPU has a significant and positive impact on the volatility of the US stock market. The COVID‐19, EPU, and volatility variables are cointegrated and move in a unidirectional way. This study considers the presence of a long‐run relationship among the variables and concludes that the US stock market is more exposed to COVID‐19 compared with the rest of the world.

AbstractBackgroundColorectal cancer (CRC) is one of the most common obesity‐associated cancers. Inflammation is also considered the most important factor between obesity and CRC. This study aimed to examine miRNAs binding sites variants on inflammatory genes identified using bioinformatics and systematic approach on clinical samples that were collected from CRC patients and controls.MethodsThe candidate variants related to CRC inflammatory genes were obtained from genome‐wide association studies and their population‐specific haplotypes. The variants were analyzed according to their genomic position on the miRNA targetome. Targetome variants in inflammation‐related genes were selected for genetic association study by TaqMan genotyping assay.ResultsThe GG genotype of rs7473 decreased the risk of obesity (p < 0.05). Heterozygous genotype (GA) of rs1547715 decreased the risk of CRC (p < 0.05). In the rs7473/rs1547715 genotype and haplotype, the frequencies of AA/GA and GG/AA lessened in CRC and obesity, respectively (p < 0.05).ConclusionsThe variants of rs7473 and rs1547715 were associated with obesity and CRC, respectively. The above‐mentioned associations could be made based on the interactions of these variants with miRNAs.

Published: April 2022

AbstractBiomass mainly consists of three major components, i.e., cellulose, hemicellulose, and lignin. Before conversion of biomass into useful products, its pretreatment is required in order to minimize the lignin contents as much as possible because lignin is the major component that obstructs the conversion of biomass into useful products. There are many technologies like, e.g., acid/alkali pretreatment and organosolv pretreatment available for the said purpose. In this study, the low‐cost ionic liquid, triethylammonium hydrogen sulfate, is used for the pretreatment of biomass. The ionic liquid was synthesized in the laboratory. About 80 % of the lignin was removed from the given biomass (corn straw) at a temperature of 78 °C, i.e. the boiling point of ethanol, and atmospheric pressure, whereas the ionic liquid was regenerated at the end of the process, making the process green and environment friendly.

AbstractThe Box‐Behnken experimental design method was applied to study optimization of dry reforming of methane over a magnesia‐supported nickel catalyst (Ni/MgO). The catalyst was prepared by impregnation method and characterized using Brunauer‐Emmett‐Teller analysis, X‐ray diffraction, thermogravimetric analysis, and transmission electron microscopy. Response surface methodology (RSM) modified by the Box‐Cox method was applied to investigate the effect of different operating parameters on conversion and formation of the different components of the reaction system. The RSM‐generated predictive models verified by analysis of variance were used to simulate the responses of the operating variables. This study revealed that the reaction temperature has the most pronounced effect followed by the CO2/CH4 mole ratio while the gas hourly space velocity had a negligible impact.

Published: April 2022

AbstractHighly ordered TiO2 nanostructures, known as nanotube arrays (NTAs), exhibit potential in various energy, chemical sensing, and biomedical applications. Owing to its simplicity and high degree of control, titanium anodization serves as the prevailing NTA synthesis method. However, the practicality of this approach is marred by sluggish and inconsistent growth rates, on the order of 10 nm min−1. Growth rates strongly depend on the electrolyte conductivity, yet most reports neglect to consider this property as a measured and controllable parameter. Here, we have systematically determined a broad set of conditions (at 60 V applied potential, elevated temperatures) that allow researchers to fabricate NTAs quickly and simply. By modulating conductivity through variation of bulk electrolyte temperature and the controlled addition of several hydroxy acid species, we achieve consistent accelerated growth up to 10 times faster than traditional methods. We find that regulating the solution conductivity within a desired region (e. g., ∼800–1000 μS cm−1) enabled the fabrication of double‐sided NTA layers of around 10 μm and 90 μm NTA in 10 and 180 min, respectively.
Hybrid deep‐Q Elman neural network for crop prediction and recommendation based on environmental changes
Authors: Shingade Sachin Dattatraya , Mudhalwadkar Rohini Prashant 
Published: April 2022

AbstractCrop recommendation is a potential research topic that relies on environmental conditions such as temperature, humidity, rainfall, and soil pH to identify suitable crops for cultivation. There are diverse models available in the literature for crop recommendation. Still, those models are not accurate enough to predict the appropriate crop when there is a sudden change in the environmental factors. The models cannot map the raw data exactly with the prediction values, and the output relies on the quality of the input features used. To resolve these issues, the concept of Q‐learning is hybridized with deep learning to enable exact mapping of the raw data with the prediction values. In this article, Q‐learning is combined with the Elman neural network, trained with the input parameters selected by the improved Archimedes optimization algorithm from the dataset. The model evaluations are carried out with the user dataset constructed using the sensor information collected from the regions of Maharashtra. The overall accuracy provided by the proposed crop recommendation model is 99.44%, and the average inference time of the model is 0.0117 s.

Published: April 2022

AbstractThis single‐arm, repeated measures study investigated the impact caregiver trauma history may have on treatment response following an intensive, 2‐day Emotion Focused Family Therapy (EFFT) caregiver workshop. Caregivers (n = 243) completed questionnaires regarding their child's emotion regulation and clinical symptoms, as well as their own childhood trauma history (i.e., exposure to various forms of child maltreatment), caregiver self‐efficacy and caregiver blocks (e.g., fears) to support their child's treatment and recovery. Questionnaires were administered prior to and immediately following the workshop and again 4, 8 and 12 months later. At baseline, caregivers who reported experiences of childhood maltreatment demonstrated more blocks compared with caregivers who did not (B = 6.35, SE = 2.62, p < 0.05). Results indicated that caregivers with and without maltreatment histories reported similar, significant gains in their child's total difficulties (B = 0.64, SE = 0.41, p = 0.12) and emotional negativity and lability (B = 0.51, SE = 0.48, p = 0.29) at 12‐month post‐workshop. Caregivers with maltreatment histories reported greater improvements in caregiver blocks (B = 5.15, SE = 1.34, p < 0.001) and child emotion regulation (B = 0.90, SE = 0.18, p < 0.001) than caregivers without maltreatment histories. They also report less, but still significant, improvement in parental self‐efficacy (B = −0.68, SE = 0.26, p < 0.01) when compared with caregivers without maltreatment histories. Findings suggest that EFFT workshops may be an acceptable and effective trans‐diagnostic intervention for families presenting with complex histories, including caregiver exposure to childhood maltreatment.

Published: April 2022

SummaryOscillation issues of the gird‐connected offshore wind farm through the voltage‐source converter‐based high‐voltage direct current (VSC‐HVDC) have serios influence on the grid stability. However, in the previous modeling and analysis for the VSC‐HVDC system, the receiving‐end inverter station is usually considered as a constant voltage source, neglecting the impact of the inverter and AC grid. In addition, the commonly used mitigation method by modifying control parameters usually does not consider its influence on the controller's control performance. To analyze the system stability more rigorously and suppress the oscillation effectively, in this work, we firstly establish a detailed impedance model of VSC‐HVDC considering the inverter station and DC transmission line, based on which the stability analysis is also presented. Furthermore, an oscillation suppression method based on intelligent impedance optimization is proposed, which is solved by Particle swarm optimization (PSO) algorithm. The proposed impedance optimization method can achieve the maximum stability margin while the transient dynamic performance is still guaranteed, thereby suppressing the oscillation of the system. Simulations are conducted in PSCAD/EMTDC to validate the accuracy and effectiveness of the proposed modeling and suppression method.

AbstractAimsOutcome predictors in myocarditis are not well defined; we aimed at identifying predictors of death, heart transplantation (HTx) and relapse before the introduction of immunosuppression.Methods and resultsFrom 1992 to 2012, 466 consecutive patients (68% male, mean age 37 ± 17 years, single centre recruitment, median follow‐up 50 months) were included, of whom 216 had clinically suspected and 250 biopsy‐proven myocarditis. Serum anti‐heart (AHA) and anti‐intercalated disk (AIDA) autoantibodies were measured by indirect immunofluorescence. Univariable and multivariable analyses of clinical and diagnostic features at diagnosis were performed. Survival free from death or HTx at 10 years was 83% in the whole study population and was lower in biopsy‐proven versus clinically suspected myocarditis (76% vs. 94%, p < 0.001). Female gender (hazard ratio [HR] 2.7, 95% confidence interval [CI] 1.1–6.5), fulminant presentation (HR 13.77, 95% CI 9.7–261.73), high‐titre organ‐specific AHA (HR 4.2, 95% CI 1.2–14.7) and anti‐nuclear antibodies (ANA) (HR 5.2, 95% CI 2.1–12.8) were independent predictors of death or HTx; higher echocardiographic left ventricular ejection fraction (LVEF) at diagnosis was protective, with a 0.93‐fold risk reduction for each 1% LVEF increase (95% CI 0.89–0.96). History of myocarditis at diagnosis (HR 8.5, 95% CI 3.5–20.7) was an independent predictor of myocarditis relapse at follow‐up; older age was protective (HR 0.95, 95% CI 0.91–0.99). Predictors of death, HTx and relapse did not differ in biopsy‐proven versus clinically suspected myocarditis.ConclusionsYoung age and a previous myocarditis were independent relapse predictors; female gender, fulminant onset, lower LVEF at presentation and high‐titre organ‐specific AHA and ANA were independent predictors of death and HTx, suggesting that autoimmune features predict worse prognosis.

Published: April 2022

AbstractThis work presents development of an innovative CuO/nitrogen‐doped carbon composite (CuO−C) that may be effectively applied for the modification of a glassy carbon electrode (GCE) and creation of a non‐enzymatic sensor for glucose detection. The structure of the CuO−C nanostructured material was analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, and atomic absorption spectroscopy. The prepared electroactive material, based on CuO including carbon structures derived from chitosan, showed excellent performance in terms of electrocatalytic oxidation of glucose. Under optimal conditions, the modified electrode displays high sensitivity (1546 μA mM−1 cm−2), a low detection limit (1.95 μM) and short response time (4 s).

Published: April 2022

AbstractA urinary pCO2 measurement system with a miniature planar CO2 probe has been developed for monitoring pCO2 levels in the urine (U‐pCO2) of catheterized septic shock patients. U‐pCO2 may provide timely recognition of changes in the microcirculatory status of patients and used as an “early” warning of metabolic‐cellular dysfunction. The utility of the U‐pCO2 sensor has been demonstrated in monitoring experiments in a model bladder. The agreement between U‐pCO2 values measured with the planar pCO2 probe and a commercial pCO2 probe in pooled urine samples projects the possibility of the implementation of the U‐pCO2 measurement system for bedside monitoring.

Published: April 2022

AbstractThe work presents the results of thermal performance and mold discoloration of thermally modified wood‐based composites incorporating multicomponent fatty acids as a bio‐based phase change materials (BPCM). Thermally modified Scots pine (TMP), beech (TMB), and spruce (TMS) sapwood were impregnated with a multicomponent mixture of linoleic acid and coconut oil fatty acids at a ratio of 20:80. Samples with different BPCM uptakes were analyzed in the temperature range typical for building indoor conditions. Leakage tests were conducted and revealed that the maximum leakage for all the samples is 3% to 5%. T‐history and heat flowmeter methods were used to evaluate the thermal characteristic of the composites. The incorporation of BPCM into thermally modified woods (TMWs) resulted in significant thermal mass improvements, expressed by the ability of the composites to store excessive energy in terms of latent heat and keep the temperature constant for long time. The specific heat capacity of the TMWs was around 2 J/g K, which increased to 4 to 8 J/g K after impregnation with BPCM, depending on the impregnation uptake. Results showed also that TMB has higher thermal conductivity than TMP and TMS, while incorporating of BPCM into these materials resulted in even improved thermal conductivity. Results showed that the thermal conductivity of TMP increased after incorporation of BPCM from 0.06 W/m K to 0.1 and 0.14 W/m K for TMP/BPCM with 48% and 95% uptake respectively. Mold tests showed that BPCM encapsulated in TMWs is less susceptible to mold discoloration compared to untreated wood.

AbstractObjectivesFetal ventriculomegaly is associated with varying degrees of genetic and structural abnormalities. The objective was to present the experience of fetal ventriculomegaly in a large European center in relation to: 1. grade of ventriculomegaly; 2. additional chromosomal/structural abnormalities; and 3. perinatal survival rates.MethodsThis was a prospective observational study of patients referred with fetal ventriculomegaly from January 2011 to July 2020. Data were obtained from the hospital database and analyzed to determine the rate of isolated ventriculomegaly, associated structural abnormalities, chromosomal/genetic abnormalities, and survival rates. Data were stratified into three groups; mild (Vp = 10–12 mm), moderate (Vp = 13–15 mm) and severe (Vp > 15 mm) ventriculomegaly.ResultsThere were 213 fetuses included for analysis. Of these 42.7% had mild ventriculomegaly, 44.6% severe and 12.7% had moderate ventriculomegaly. Initial ultrasound assessment reported isolated ventriculomegaly in 45.5% fetuses, with additional structural abnormalities in 54.5%. The rate of chromosomal/genetic abnormalities was high,16.4%. After all investigations, the true rate of isolated VM was 36.1%. The overall survival was 85.6%. Survival was higher for those with isolated VM across all groups (P < 0.05).ConclusionVentriculomegaly is a complex condition and patients should be counselled that even with apparently isolated VM, there remains the possibility of additional genetic and/or structural problems being diagnosed in up to 10% of fetuses.

AbstractObjectiveTo assess the prevalence of chronic endometritis (CE) among infertile women with endometrial polyps (EP).MethodsFrom June 2017 to October 2021, 583 patients in the polyp group (group A—group A1: single‐polyp group, 322 patients; group A2: multiple‐polyp group, 261 patients) and 4534 patients in the non‐polyp group (group B) were included in this retrospective study. Hysteroscopic polypectomy was performed in group A. Endometrial biopsy and CD138 immunohistochemistry staining for specimens was carried out in all groups.ResultsPrevalence of CE was significantly higher in group A than in group B (45.28% vs. 27.94%, P < 0.001). A significantly higher prevalence of CE was found in group A1 and group A2 compared with group B (42.24% vs. 27.94%, P < 0.001; 49.04% vs. 27.94%, P < 0.001; respectively). No significant difference in the comparison of CE prevalence was found between group A1 and group A2. Similar results were achieved in the subgroup analysis among patients aged 40 years or older and patients younger than 40 years.ConclusionEP, either single EP or multiple EP, positively correlates with CE. The prevalence of CE was similar between the single‐polyp group and the multiple‐polyp group.
