Authors: Dubey Krati , Pandey Sudhakar , Kumar Sanjay 
Published: October 2023

SummaryCloud‐assisted IoT networks, (Fog computing) provide computation‐intensive services to the edge devices like the Internet of Things (IoT) with limited resources. One of the urgent challenges in fog‐based IoT networks is how to fulfill the demanded network resources for connected IoT devices with secure communication. To provide robust solutions in this paper, we have proposed a secrecy‐enabled resource allocation scheme for cloud‐assisted IoT networks (fog networks). In this study, we have conceptualized a state‐of‐the‐art physical‐layer secure communication along with the network resource allocation scheme with the intention of providing on‐demand Quality of service (QoS) parameters along with increased secrecy rate in the cloud‐assisted IoT networks. To determine this we have formulated a coalition‐based game formation for the considered network. Different from previous work we include the secrecy in the physical layer by the proposed secracy‐enabled resource allocation scheme. Furthermore, we have conducted extensive simulations for analyzing the numerical results of the proposed scheme. The numerical result shows the effectiveness of the proposed scheme in terms of increased secrecy and data rate of the IoT devices.

Differences in perceived online communication and disclosing e‐motions among adolescents and young adults: The role of specific social media features and social anxiety
Authors: Angelini Federica , Gini Gianluca 
Published: October 2023

AbstractIntroductionSocial media are widely used by adolescents and young adults as a mean to maintain interpersonal relationships. Recent studies have found that young individuals with high levels of social anxiety feel more confident in communicating online. However, little is known about the role of perceived social media characteristics that could minimize the distress they experienced in face‐to‐face interactions. In this study, we rely on the tenets of the Transformation Framework, according to which social media, with its own features, may transform social relationships, including disclosing emotions and communicating with others online, in ways that may differ across individuals with or without specific vulnerability (e.g., social anxiety). Therefore, this cross‐sectional study aims at examining the contribution of three specific social media features (i.e., asynchronicity, cue absence, and visualness) in explaining perceived breadth and depth of online communication, both directly and via e‐motional processes (i.e., expression and facilitating use of e‐motions), across groups of individuals with high versus low levels of social anxiety.MethodsParticipants were 1046 Italian adolescents and young adults (61.4% females; Mage = 17.9, SD = 3.23) who completed an anonymous self‐report questionnaire between 2021 and 2022. Participants with very high scores on social anxiety (above the 90th percentile; socially anxious), were distinguished from all others (socially nonanxious) and a multigroup analysis (MGA) was run to compare the pattern of associations across the two different groups.Results and ConclusionResults from the MGA showed significant differences between the two groups, partially confirming our hypotheses. Specifically, among socially anxious individuals, perceived cue absence was found to benefit perceived breadth and depth of online communication, and asynchronicity to enhance online emotional processes; conversely, these associations were negative in the group of socially nonanxious. Thus, these findings underly the contribution of social media in explaining youngsters' online experiences and support the potential beneficial role of some social media features for those more socially vulnerable.

Published: September 2023

AbstractEndogenous formaldehyde (FA) is produced in the human body via various mechanisms to preserve healthy energy metabolism and safeguard the organism. However, endogenous FA can have several negative effects on the body through epigenetic alterations, including cancer growth promotion; neuronal, hippocampal and endothelial damages; atherosclerosis acceleration; haemopoietic stem cell destruction and haemopoietic cell production reduction. Certain medications with antioxidant effects, such as glutathione, vitamin E, resveratrol, alpha lipoic acid and polyphenols, lessen the detrimental effects of endogenous FA by reducing oxidative stress, directly scavenging endogenous FA or promoting its degradation. This study offers fresh perspectives for managing illnesses associated with endogenous FA exposure.

Published: September 2023

AbstractBACKGROUNDAu/ZnO systems have been investigated in recent years as alternatives to improve the photocatalytic performance obtained by pure ZnO and other nanocatalysts based on ZnO nanostructures. ZnO nanoparticles and Au/ZnO nanocatalysts were successfully synthesized by facile and low‐cost methods, such hydrothermal synthesis and chemical reduction method, respectively. The plasmonic nanocatalysts were fabricated at different Au precursor (HAuCl4) concentrations (0.5–5 mM) to obtain different Au contents (0.31–13.9 at.%) on the ZnO surface. The influence of Au content on the ZnO surface and its photocatalytic activity was studied.RESULTSThe photocatalytic activities of pure ZnO and Au/ZnO nanocatalysts were evaluated in the photodegradation of methylene blue (MB) solution under UV light. The Au/ZnO nanocatalyst with the lowest Au content (0.31 at.%) showed the best photocatalytic performance, reaching an MB degradation rate of 99.99% within 60 min (an enhancement of 60% compared with ZnO nanoparticles) and a reaction rate constant of 4.186 min−1 (×10−2), which is higher than those of other novel and complex nanocatalysts based on ZnO. Moreover, five cycles of self‐cleaning and an outstanding durability of 25 aging months were obtained during photocatalytic applications.CONCLUSIONAs demonstrated, a high amount of Au nanospheres on the ZnO surface is not necessary to enhance its photocatalytic activity. This synthesis process offers the possibility of obtaining the optimum amount of Au loading over the ZnO surface to reach a better photocatalytic performance, good self‐cleaning ability, and outstanding durability in comparison with other complex and recently reported catalysts (composites based on ZnO nanostructures). © 2023 Society of Chemical Industry (SCI).

AbstractBackgroundAnophthalmia and microphthalmia are severe developmental ocular disorders that affect the size of the ocular globe and can be unilateral or bilateral. The disease is found in syndromic as well as non‐syndromic forms. It is genetically caused by chromosomal aberrations, copy number variations and single gene mutations, along with non‐genetic factors such as viral infections, deficiency of vitamin A and an exposure to alcohol or drugs during pregnancy. To date, more than 30 genes having different modes of inheritance patterns are identified as causing anophthalmia and microphthalmia.MethodsIn the present study, a clinical and genetic analysis was performed of six patients with anophthalmia and microphthalmia and/or additional phenotypes of intellectual disability, developmental delay and cerebral palsy from a large consanguineous Pakistani family. Whole exome sequencing followed by data analysis for variants prioritization and validation through Sanger sequencing was performed to identify the disease causing variant(s). American College of Medical Genetics and Genomics (ACMG) guidelines were applied to classify clinical interpretation of the prioritized variants.ResultsClinical investigations revealed that the affected individuals are afflicted with anophthalmia. Three of the patients showed additional phenotype of intellectual disability, developmental delays and other neurological symptoms. Whole exome sequencing of the DNA samples of the affected members in the family identified a novel homozygous stop gain mutation (NM_012186: c.106G>T: p.Glu36*) in Forkhead Box E3 (FOXE3) gene shared by all affected individuals. Moreover, patients segregating additional phenotypes of spastic paraplegia, intellectual disability, hearing loss and microcephaly showed an additional homozygous sequence variant (NM_004722: c.953G>A: p.Arg318Gln) in AP4M1. Sanger sequencing validated the correct segregation of the identified variants in the affected family. ACMG guidelines predicted the variants to be pathogenic.ConclusionsWe have investigated first case of syndromic anophthalmia caused by variants in the FOXE3 and AP4M1. The present findings are helpful for understanding pathological role of the mutations of the genes in syndromic forms of anophthalmia. Furthermore, the study signifies searching for the identification of second variant in families with patients exhibiting variable phenotypes. In addition, the findings will help clinical geneticists, genetic counselors and the affected family with respect to prenatal testing, family planning and genetic counseling.

AbstractBackgroundUnderweight infants with single‐ventricle cardiac physiology have been shown to have increased morbidity, mortality, and resource utilization. The purpose of this study was to determine whether patients who were overweight, as defined by weight‐for‐length z score >90th percentile, were similarly at risk for increased resource utilization, as defined by mechanical ventilation hours (VHs) and intensive care unit length of stay (ICU LOS).MethodsWe evaluated resource utilization for 109 patients from our institution who underwent bidirectional Glenn surgery from January 2010 to June 2015 and met prespecified inclusion criteria. Patients were divided into 3 groups: underweight (z score, <5th percentile), normal weight (z score, 5th–90th percentile), and overweight (z score, >90th percentile).ResultsICU LOS was longer in the overweight group (median, 18.5 days) when compared with the under‐ and normal‐weight groups (median LOS, 11 and 9 days, respectively) but did not reach statistical significance. VHs were also increased in the overweight group (median, 72 hours) when compared with the underweight (median, 27 hours) and normal weight (median, 25 hours) groups. This increase in VHs was statistically significant (P = .03).ConclusionsThis study suggests that patients with single‐ventricle physiology who are overweight at the time of their bidirectional Glenn surgery may be at risk for increased resource utilization as compared with those who meet or fail to meet their caloric recommendations. These findings represent an underappreciated risk factor in this already‐vulnerable patient population, providing potential opportunity for intervention and improved outcomes.

Published: October 2023

AbstractBACKGROUNDDetermination of composition and physicochemical parameters of natural products requires dedicated, often laborious and expensive, analytical protocols. Different spectroscopic techniques, in conjunction with chemometrics, seem to have a considerable potential in direct analysis of raw plant material and foods, without any chemical treatment.RESULTSFluorescence spectroscopy and three vibrational spectroscopy techniques were applied to determine total polyphenol content, antioxidant activity and macronutrient levels in red‐ and purple‐fleshed potato varieties. Excitation–emission matrix fluorescence, Fourier transform Raman, attenuated total reflection Fourier transform infrared and near‐infrared spectra were recorded for the freeze‐dried samples. Combining spectral data and the results of reference analyses, partial least squares regression models were constructed for each parameter studied. For polyphenols and antioxidant activity, quantification errors found for validation samples amounted to 3.74–5.04% and 4.75–6.35%, respectively, whereas macronutrient analysis gave errors in the 3.45–4.55%, 3.09–5.30% and 5.10–8.58% ranges for starch, protein and sugar determinations, respectively.CONCLUSIONThe obtained results demonstrate that different spectroscopic techniques in combination with multivariate modeling allow simultaneous determination of various parameters of plant samples based on a single sample spectrum. They can effectively replace commonly used protocols of food product analysis requiring sample dissolving and extraction of the compounds of interest. © 2023 Society of Chemical Industry.
Liquid–Liquid Equilibrium in Xylene Solubles (XS) Analysis of Polypropylene
Authors: Melo Afrânio , Pessoa Fernando L. P. , Pinto José Carlos 
Published: October 2023

AbstractA multicomponent Flory‐Huggins model is implemented and utilized to describe the liquid–liquid equilibrium phenomenon in mixtures of polypropylene and xylene, in the context of the well‐known xylene solubles (XS) test. The XS experiment is a common procedure in many polymer laboratories, used to determine the percentage of xylene solubles in samples of polypropylene, which provides an approximate measure of the atactic and oligomeric chains. Despite the importance of the test, the literature lacks a thermodynamic perspective regarding the description of this extraction phenomenon. In the present study, the Flory‐Huggins interaction parameter is adjusted in a multicomponent framework to ensure that equilibrium chain length distributions calculated with the proposed model best match experimental distributions. It is shown that the experimental data obtained from XS analyses can be accurately fitted by the proposed model and that the estimated Flory‐Huggins interaction parameter is more sensitive to the polymer average molar mass than to the degree of tacticity, when a particular catalyst is considered.

Published: October 2023

AbstractDynamic liquid crystal elastomers (LCEs) are a class of polymer networks characterized by the inclusion of both liquid crystalline monomers and dynamic covalent bonds. The unique properties realized through the combination of these moieties has produced a plethora of stimuli‐responsive materials to address a range of emerging technologies. While previous works have studied the incorporation of different dynamic bonds in LCEs, few (if any) have studied the effect of the specific placement of the dynamic bonds within an LCE network. A series of dynamic LCE networks were synthesized using a generalizable approach that employs a tandem thiol‐ene/yne chemistry which allows the location of the dynamic disulfide bond to be varied while maintaining similar network characteristics. When probing these systems in the LC regime, the thermomechanical properties were found to be largely similar. It is not until elevated temperatures (160–180 °C) that differences in the relaxation activation energies of these systems begin to materialize based solely on differences in placement of the dynamic bond throughout the network. This work demonstrates that through intentional dynamic bond placement, stress relaxation times can be tuned without affecting the LCE character. This insight can help optimize future dynamic LCE designs and achieve shorter processing times.

Published: September 2023

AbstractBACKGROUNDSeptoria tritici blotch caused by Zymoseptoria tritici continues to be one of the most economically destructive diseases of winter wheat in north‐western Europe. Control is heavily reliant on the application of fungicides, in particular those belonging to the azole group. Here we describe the sensitivity of European Z. tritici populations to the novel azole mefentrifluconazole and the analysis of associated mechanisms of resistance.RESULTSA wide range of sensitivity to mefentrifluconazole was observed amongst the Z. tritici collections examined, with strong cross‐resistances also observed between mefentrifluconazole, difenoconazole and tebuconazole. Overall, the Irish population displayed the lowest sensitivity to all azoles tested. Further detailed analysis of the Irish population in 2021 demonstrated differences in sensitivity occurred between sampling sites, with these differences associated with the frequencies of key resistance mechanisms (CYP51 alterations and MFS1 promoter inserts linked to overexpression). Under glasshouse conditions reductions in the efficacy of mefentrifluconazole were observed towards those strains exhibiting the lowest in vitro sensitivities.CONCLUSIONSThis study demonstrates that a large range of sensitivity to mefentrifluconazole exists in European Z. tritici populations. Those strains exhibiting the lowest sensitivity to the azoles tested had the most complex CYP51 haplotypes in combination with the 519 bp insert, associated with enhanced activity of MFS1. The future use of mefentrifluconazole should take these findings into consideration to minimise the selection of these strains. © 2023 The Authors.

AbstractKava is a South Pacific plant‐based medicine with anxiolytic properties, but little is known about the impact kava has on gene expression or whether gene expression can serve as a marker of kava response. This study aimed to determine whether kava treatment alters the expression of genes with physiological relevance to anxiety pathophysiology and whether the baseline expression of these physiologically relevant genes modifies the efficacy of kava treatment. In this post hoc analysis, we examined the expression of 48 genes relevant to the pathophysiology of anxiety collected from a double‐blind randomized controlled trial that assessed the efficacy of kava treatment in generalized anxiety disorder. Peripheral blood gene expression was measured in 71 (34 kava, 37 placebo) adults at baseline and in 40 (19 kava, 21 placebo) after 8 weeks of treatment by reverse transcription polymerase chain reaction (PCR). Results revealed that kava decreased the expression of a subunit of the GABAA‐rho receptor gene (GABRR2) and catechol‐O‐methyltransferase (COMT), a gene related to catecholamine metabolism. Kava efficacy was not found to be modified by baseline (pretreatment) expression of relevant genes. Although these results did not withstand statistical correction for multiple comparisons and require external validation, they support the notion that kava's mechanism of action includes interaction with GABAergic and catecholaminergic systems.

Assessable and interpretable sensitivity analysis in the pattern graph framework for nonignorable missingness mechanisms
Authors: Zamanian Alireza , Ahmidi Narges , Drton Mathias 
Published: September 2023

The pattern graph framework solves a wide range of missing data problems with nonignorable mechanisms. However, it faces two challenges of assessability and interpretability, particularly important in safety‐critical problems such as clinical diagnosis: (i) How can one assess the validity of the framework's a priori assumption and make necessary adjustments to accommodate known information about the problem? (ii) How can one interpret the process of exponential tilting used for sensitivity analysis in the pattern graph framework and choose the tilt perturbations based on meaningful real‐world quantities? In this paper, we introduce Informed Sensitivity Analysis, an extension of the pattern graph framework that enables us to incorporate substantive knowledge about the missingness mechanism into the pattern graph framework. Our extension allows us to examine the validity of assumptions underlying pattern graphs and interpret sensitivity analysis results in terms of realistic problem characteristics. We apply our method to a prevalent nonignorable missing data scenario in clinical research. We validate and compare our method's results of our method with a number of widely‐used missing data methods, including Unweighted CCA, KNN Imputer, MICE, and MissForest. The validation is done using both boot‐strapped simulated experiments as well as real‐world clinical observations in the MIMIC‐III public dataset.

Published: October 2023

AbstractThe service life of soluble lead flow batteries can be extended by periodic addition of H2O2, especially when it failed. However in first few cycles after H2O2 treatment, its coulombic efficiency is very low. To clarify it, the properties of electrode and electrolyte, and cycle performance have been systematically analyzed. It has been found that the negative/positive electrode reactions have serious overpotentials during early charging due to oxygen, which are produced and dissolved into the electrolyte during H2O2 treatment. With increasing the cycle number, the polarization degree decreases to the normal level of the battery. To solve it, oxygen is removed using argon after H2O2 treatment. The flow cell is normally recovered in the cycling performance. The average coulomb efficiency is 94.5±5.8 % for 500 times. After H2O2 treatment and oxygen removal, it exhibits a good cycling performance at the average coulomb efficiency of 93.9±4.2 % for another 500 times.
