Published: March 2023

SummaryDesigning an energy efficient and durable wireless sensor networks (WSNs) is a key challenge as it personifies potential and reactive functionalities in harsh antagonistic environment at which wired system deployment is completely infeasible. Majority of the clustering mechanisms contributed to the literature concentrated on augmenting network lifetime and energy stability. However, energy consumption incurred by cluster heads (CHs) are high and thereby results in minimized network lifetime and frequent CHs selection. In this paper, a modified whale‐dragonfly optimization algorithm and self‐adaptive cuckoo search‐based clustering strategy (MWIDOA‐SACS) is proposed for sustaining energy stability and augment network lifetime. In specific, MWIDOA‐SACS is included for exploiting the fitness values that aids in determining two optimal nodes that are selected as optimal CH and cluster router (CR) nodes in the network. In MWIDOA, the search conduct of dragon flies is completely updated through whale optimization algorithm (WOA) for preventing load balancing at CHs. It minimized the overhead of CH by adopting CHs and CR for collecting information from cluster members and transmitting the aggregated data from CHs to the base station (BS). It included self‐adaptive cuckoo search (SACS) for achieving sink mobility using radius, energy stability, received signal strength, and throughput for achieving optimal data transmission process after partitioning the network into unequal clusters. Simulation experiments of the proposed MWIDOA‐SACS confirmed better performance in terms of total residual energy by 21.28% and network lifetime by 26.32%, compared to the competitive CH selection strategies.

AbstractObjectiveFerritin levels are well known to be associated with gestational diabetes mellitus (GDM). However, the association of the combination of ferritin and triglyceride (TG) levels in early mid‐pregnancy with GDM has not been studied in depth. We investigated the independent and combined relationships of plasma ferritin and TG concentrations with the risk of GDM as well as the mediation effect of TG on ferritin.MethodsWe analysed 2071 pregnant women from the Tongji Maternal and Child Health Cohort who had their plasma ferritin and TG concentrations measured at 11–20 weeks of gestation. Associations between ferritin and TG concentrations and GDM risk were estimated using multivariable logistic regression models. Youden's index was calculated to find the cut‐off values of ferritin and TG by ROC curve analysis. The mediation effect of the TG concentration on the ferritin level with GDM risk was explored by a mediation analysis.ResultsA total of 264 (12.3%) participants developed GDM. The median and IQR of ferritin was 53.9 (30.5–92.7) ng/mL. After adjusting for potential confounders, the relative risks (RRs) and 95% confidence intervals of GDM were 2.19 (1.42, 3.39) for ferritin and 2.02 (1.37, 2.97) for TG. The adjusted RR for combination was 2.40 (1.62, 3.55). Moreover, we found that the TG concentration mediated 15.0% of the total effect of the ferritin concentration on the risk of GDM.ConclusionsWomen with a combination of both high plasma ferritin (˃55.7 ng/mL) and high TG (˃1.9 mmoL/L) were at the highest risk of GDM. Additionally, we have revealed for the first time that an elevated maternal TG concentration in early pregnancy mediates the relationship between ferritin concentration and GDM risk.Trial registrationThis trial is registered at https://ClinicalTrials.gov as NCT03099837.

AbstractAn iron‐catalyzed trifluoromethylation of indole‐tethered alkene with Togni's reagent to construct CF3‐containing spiro[indole‐3,3′‐pyrrolidine] and tetrahydrocarbazole derivatives under mild and convenient conditions has been disclosed. Mechanistic studies indicate that the reaction proceed through a CF3 radical addition to the alkene, followed by sequential dearomatizing spiocyclization of the indole and oxidation to afford the spiro[indole‐3,3′‐pyrrolidine] derivatives. Meanwhile, when the substituent at the C2 position of the indole is hydrogen, the CF3‐containing tetrahydrocarbazole is obtained through trifluoromethylation of alkene and cyclization of indole.
The role of risk measures in relating earthquake risks at building and portfolio levels

Published: March 2023

AbstractThe potentially large spatial footprint of earthquake disasters and the increased concentration of population and values in dense urban areas call for an explicit consideration of seismic risk at a regional, building portfolio level. The relation between the building‐level seismic risk and the portfolio‐level seismic risk is helpful if one wants to meet a specific regional seismic risk tolerance level by specifying seismic risk targets for individual buildings. We examine four types of common risk measures and point to the importance of subadditivity, a risk measure mathematical property, for deriving a conservative upper‐bound relation between the building‐specific and the building portfolio seismic risks. Subadditive risk measures, such as the Expected Shortfall, allow estimates of conservative upper bounds of the portfolio‐level seismic risk. In a case study, we show that nonsubadditive risk measures commonly used in earthquake engineering can lead to counter‐intuitive and nonconservative perceptions of the regional seismic risk, especially when one extrapolates from individual buildings to the entire building portfolio. We also illustrate the advantages of subadditive risk measures for regional seismic risk assessment.

AbstractIn the industrial sector, hot water applications constitute a significant share of final energy consumption. This creates a wide demand‐supply energy gap that must be bridged by integrating renewable sources with conventional fuels. This paper presents the performance analysis of a solar water heating system based on an evacuated flat‐plate collector (EFPC) with a surface area of 4 m2. A water–glycol mixture was used as the heat transfer fluid (HTF) with mass flow rates of 0.03, 0.0336, and 0.0504 kg/s under a vacuum pressure of –0.8 bar created inside the collector. A detailed numerical model was developed in MATLAB for the proposed EFPC system, followed by experimental validation. A maximum root mean square error of 2.81 for the absorber temperature and a percentage error of 6.62 was observed for the thermal efficiency in model validation. This substantiates the model's capability to predict actual system performance with reasonable accuracy. The maximum thermal efficiency of the EFPC is 78% with a maximum fluid outlet temperature of 98°C in June and 69°C in January. The maximum useful energy extracted is 1300 W in January. Additionally, the effect of design parameters on system performance such as mass flow rates, collector areas, tube spacing, and different HTF mixtures is simulated. Lastly, an economic analysis of the EFPC was conducted for hot water demand in a textile industry. The results revealed a payback period of 7.4 years, which highlights the feasibility of this system.

AbstractIn this study, we designed and optimized the main process for CO2 cryogenic separation and purification as well as the auxiliary process of refrigeration with ammonia, both these processes are modeled using Aspen HYSYS V11. The energy‐saving potential and greenhouse gas emission reduction potential of the process flow were analyzed using the Aspen Energy Analyzer V11. The effects of the plant inlet pressure, cooling temperature, tower pressure, and number of stages on two key parameters (energy consumption per unit of product and CO2 recovery rate) were studied in detail. Simultaneously, the appropriate design parameters of the plant were obtained, and the reason for the variation law was analyzed. Finally, grey relational analysis was used to explore the correlation between the influence factors and key parameters, indicating that the number of stages has the largest impact on the CO2 recovery rate and the energy consumption per unit of product, whereas tower pressure and cooling temperature have the least impact on the CO2 recovery rate and energy consumption per unit of product, respectively.
Fire‐suppression efficiency and extinguishing mechanisms of calcium acetate using heptane cup‐burner flames
Authors: Koshiba Yusuke , Hirakawa Yuichi 
Published: March 2023

AbstractTo address the global requirement for a phosphorus‐free fire‐extinguishing agent, this study elucidated the ability of calcium acetate to extinguish cup‐burner flames. The inhibition efficiency of calcium acetate powder (<50 μm) was compared with that of silica‐uncoated ammonium dihydrogen phosphate (<50 μm), a chemical contained in agents used in typical ABC fire extinguishers. Calcium oxide and calcium carbonate powders were also used to investigate the suppression mechanisms of calcium acetate. The cup‐burner experiments demonstrated that (i) calcium acetate, calcium hydroxide, and ammonium dihydrogen phosphate could extinguish cup‐burner flames; (ii) calcium carbonate could not extinguish cup‐burner flames; and (iii) the fire‐suppression ability of calcium acetate was higher than that of ammonium dihydrogen phosphate, which was in turn higher than that of calcium hydroxide. Thermogravimetric analysis (TG) and X‐ray diffraction measurements revealed that, although the calcium‐compound powders decomposed and produced calcium oxide during flame extinction, significant differences existed among the fire inhibition efficiencies of the calcium compounds. TG and particle‐size measurements proved that the high fire‐suppression ability of calcium acetate resulted from the high ability of calcium acetate to generate inert gases during its decomposition, which diluted the oxygen concentration, thereby extinguishing the fires.

AbstractInfrared (IR) drying is an effective method for the preservation and processing of carmine radish (Raphanus sativus L.). This study aimed to investigate the effects of different IR radiation intensities (2125, 2780, and 3358 W/m2) on the drying properties and flavor components of carmine radish slices. As the IR radiation intensity and the drying temperature increased, the total drying time, the moisture content, and the dehydration rate reduced continuously, while the hardness of carmine radish slices decreased and then increased. Drying at a radiation intensity of 2780 and 3358 W/m2 reduced 50% and 70% of the drying time compared to that of 2125 W/m2, respectively. Flavor components of carmine radish showed apparent changes during the IR drying process with a radiation intensity of 2125 W/m2. IR drying at a lower intensity was beneficial to the retention of volatile flavor components. The retention of volatile substances at an intensity of 2125 W/m2 for 15 min was 1.97 and 1.68 times that for 30 min and control samples, respectively. Consequently, to retain good processing quality and flavor properties of carmine radish slices, the optimal drying parameter of IR within this study was an IR radiation intensity of 2125 W/m2 for about 15 min.
VIM::KMT2A‐rearranged sarcomas: A report of two new cases confirming an entity with distinct histologic features

Published: March 2023

AbstractThe recently described KMT2A‐rearranged sarcomas are rare emerging entities where the KMT2A gene fuses with YAP1 and, less commonly, VIM, resulting in two distinct morphologies. Unlike the sclerosing epithelioid fibrosarcoma‐like features that characterize tumors with KMT2A::YAP1 fusions, VIM::KMT2A‐rearranged sarcomas are more uniformly cellular and lack the extensively sclerotic background seen in the former. Most tumors behave aggressively with metastases on presentation. Here, we describe the clinicopathologic and molecular findings in two additional cases of VIM::KMT2A rearranged sarcomas that arose in the deep soft tissues of adult males. Both tumors were composed of hypercellular fascicles of uniform spindle cells with pale eosinophilic cytoplasm and ovoid nuclei. The stroma had scant delicate collagen with occasional thin‐walled ectatic blood vessels and perivascular hyalinization. Immunohistochemical studies showed an unspecific staining pattern with diffuse positivity for CD99 and BCL2 and variable staining for S100 protein. RNA‐sequencing detected the presence of VIM::KMT2A gene fusion involving VIM exon 4 and KMT2A exon 2 in both cases. Sarcomas with VIM::KMT2A gene fusions seem to have sufficient morphologic features to warrant distinction from KMT2A‐rearranged sarcomas with YAP1 partner. Without the benefit of molecular testing, these tumors pose a diagnostic challenge due to their lack of specific immunohistochemical profile and great morphologic overlap with other monomorphic spindle cell neoplasms.

Published: March 2023

AbstractCarbon dioxide has been proved an effective agent to enhance recovery for relatively light crude oil, but its applications in heavy oil are very limited. This short communication presents field trials of CO2 huff and puff at Dagang, a heavy oil field in Northeast China. Two wells received CO2 injection, and both wells saw higher oil output and lower water‐cut after CO2 treatment. This project proves CO2 is effective for heavy oil recovery. Recommendations are also made for future CO2 huff and puff projects. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.
Sleeping accommodations for researchers increase the likelihood of biodiversity inventories in protected areas
Authors: Ferreira Gabrielly P. , Antunes Alexsander Z. , Campagnoli Mariana L. , Christianini Alexander V. 
Published: March 2023

AbstractBiodiversity assessments are important for successful conservation initiatives. However, many protected areas (PAs) still have no biodiversity inventories of important species‐rich taxa, such as invertebrates, that deliver important ecosystem services (e.g., pollination, nutrient cycling) or are biological indicators. Here, we investigated if the likelihood of having arthropod inventories in PAs (state parks) was influenced by PA size, date of PA creation, distance to the nearest university, main vegetation type (forest/savanna), and availability of accommodations for researchers by inspecting management plans from 61 PAs in southeastern Brazil. Only 13 PAs (22%) had arthropod inventories considered in park management plans. The availability of accommodations for researchers was the only variable influencing the likelihood of a PA to have arthropod inventories. A modest investment (around US$35,000 in Brazil) is required to make accommodations available for researchers in a PA and may positively impact information acquisition that is key to planning and protecting biodiversity.

AbstractIntroductionRelatively little is known about individual differences in adolescent psychological flexibility and its associations with symptoms of stress and depression. This study examined different profiles of adolescent stress and depressive symptoms and their associations with developing psychological flexibility before the critical educational transition.MethodsThe data were derived from a general sample of 740 Finnish ninth‐grade adolescents (Mage = 15.7 years, 57% female) who were assessed twice during the final grade of their basic education. The data were analyzed using growth mixture modeling.ResultsFour profiles of stress and depressive symptoms were identified during a school year: (1) no stress and no depressive symptoms (None; 69%); (2) mild and decreasing stress and depressive symptoms (Decreasing; 15%); (3) low but increasing stress and depressive symptoms (Increasing; 6%); and (4) high and stable levels of stress and depressive symptoms (High; 10%). The adolescents in these profiles differed from each other in their initial levels and changes of psychological flexibility. The initial level of psychological flexibility was highest in the no‐symptom profile group. We observed simultaneous change trends in symptoms and psychological flexibility during a school year. When symptoms decreased, psychological flexibility increased, and when symptoms increased, psychological flexibility decreased.ConclusionsA bidirectional pattern of relationships between psychological flexibility and psychological symptoms was found. Despite initially high level of skills in psychological flexibility, some adolescents, unexpectedly, experienced increased symptoms of stress and depression during the school year. The results call for further studies to explore in‐depth the developmental diversity in adolescents' well‐being and its antecedents.

AbstractIn this study, Chitosan and Chitosan‐zinc oxide (ZnO) nanocomposite were prepared and applied as a low‐cost adsorbent with high adsorption capacity for removing reactive red 198 (RR 198) dye from contaminated water. After preparation, it was characterized using FT‐IR, XRD, and SEM. The effect of pH, temperature, time, adsorbent amount, and initial dye concentration were investigated in the removal efficiency of RR 198. The maximum adsorption capacity (qm) obtained from the Langmuir equation was 172.41 mg/g in adsorbent dose of 0.1 g/L, pH: 4, temperature of 25°C, adsorption time of 40 min. The thermodynamic parameters demonstrated the spontaneous and endothermic nature of the adsorption process. Due to the high efficiency of chitosan/ZnO nanocomposite in removal of RR 198 from water and advantages such as high adsorption capacity, simple synthesis, and easy application, it can be used as an effective method in the removal of RR 198 from water.

Published: March 2023

AbstractWe explore how Arab adolescents enact critical consciousness to improve their lives and better their community. Eleven first‐ and second‐generation Arab adolescents participated in a Photovoice study and were asked to reflect on and take photos that represented their well‐being, daily life, and sense of belonging and community. The participants discussed their photos over multiple group reflection sessions. Thematic analysis highlights how Arab adolescents make positive change in their community, aided by their connections to community, their awareness of structural challenges they and their communities face, and their sense of agency to make positive change. We contribute to the literature by offering a window into the lived experiences of critical consciousness among Arab adolescents, an underrepresented group in the critical consciousness literature. We also add to the growing body of evidence that highlights the importance of “everyday activism” when considering social change actions.
Role of adipocyte‐derived extracellular vesicles during the progression of liver inflammation to hepatocellular carcinoma
Authors: Vp Venkateish , Kannan Anbarasu , Perumal Madan Kumar 
Published: March 2023

AbstractExtracellular vesicles are membrane‐bound cargos that vary in size and are stably transported through various bodily fluids. Extracellular vesicles communicate information between the cells and organs. Extracellular vesicles from the diseased cells alter cellular responses of the recipient cells contributing to disease progression. In obesity, adipocytes become hypertrophic and the extracellular vesicles from these dysfunctional adipocytes showed altered cargo contents instigating pathophysiological response leading to chronic liver diseases. In this review, the role of adipocyte‐derived extracellular vesicles on the progression of liver inflammation, fibrosis, cirrhosis, and hepatocellular carcinoma are extensively discussed. Newer approaches are crucial to take advantage of extracellular vesicles and their content as biomarkers to diagnose initial liver inflammation before reaching to an irreversible liver failure stage.

Published: March 2023

AbstractAs a well‐known porous inorganic material formed of aluminosilicate structures, Zeolit Socony Mobil Number 5 (ZSM‐5) zeolite has been widely used for various applications, especially oil‐chemical conversion processes and environmental pollution treatment. This study provides an overview of the natural sources as well as the role and categorization of structural compounds used for the synthesis of ZSM‐5. Overall, clay, natural minerals, or leftovers from agricultural and industrial activities (all of which offer several advantages, such as low cost, availability, and environmental friendliness) have been used to manufacture ZSM‐5. Moreover, green structural directing agents (known as soft templates) have been increasingly employed to replace pure chemicals in the production of ZSM‐5, aiming to decrease unexpected effects on the environment. This research orientates the production of ZSM‐5 zeolite on a low‐cost and environmentally friendly industrial scale. © 2023 Society of Chemical Industry (SCI).
