Authors: Raqib Hussain A. , Elango M. K. 
Published: May 2023

AbstractThis manuscript proposes a hybrid technique for the optimum location of micro‐phasor measurement units (μ‐PMUs) in the distribution system (DS).The proposed hybrid approach is the wrapper of dwarf mongoose optimizer (DMO) and pelican optimization algorithm (POA). The updating behavior of DMO is improved by the POA; therefore, it is called DMO‐POA approach. The main aim of the proposed approach is to avoid discontinuity of supply and minimizes the count of PMDs to reduce cost and attain the maximal count of measurement‐redundancy that is limited to full‐system observability for IEEE bus‐system in zero injection nodes (ZINs) and tie‐switches. The proposed approach considered the optimum count of μ‐PMUs is needed for the thorough distribution system economy, observability, and the reliability measure. The proposed approach considers the distribution of PMUs in the reconfiguration of smart‐distribution‐grids, ZINs and communication system requirements. Here, the objective‐function is aiming at minimizing the costs of reliability and capital. The proposed method uses the infrastructure of communication cost to simultaneously co‐optimize the system switching strategy and find the optimal sites for PMUs. The performance of the proposed technique is tested in different test‐systems, like IEEE‐14 bus, 13, 34, 37, and 123 buses and the performance is executed by comparing it with the existing approaches. Furthermore, the proposed system is effectual to find an optimal solution with less computation and decreases the complexity of the algorithm.

AbstractWith the rapid development of transportation system, the safety, reliability, and durability of green tires play an important role in modern transportation. While for the material preparation, the poor dispersion ability of reinforced filler and the weak interfacial interactions with polymer matrix seriously restricted the further application in the green tire field. Meanwhile, avoiding the use of organic solvents is also an environmental issue that needs to be considered in the preparation process. Herein, water‐soluble 2‐mercapto‐1‐methylimidazole (MMI) functionalized graphene oxide (GO‐MMI) was obtained through a simple, green and one‐step hydrothermal method. Additionally, the modified graphene oxide/natural rubber composites (GO‐MMI/NR) with different GO‐MMI content were prepared by the latex coprecipitation approach. As a result, the modified GO‐MMI could be evenly dispersed in the NR matrix through the mechanical blending and the obtained GO‐MMI/NR composites possessed the good comprehensive properties after vulcanization. Specifically, the tensile strength (26.8 MPa), elongation at break (801%), low heat build‐up (6.2°C), Deutsches Institute for Normung (DIN) abrasion loss volume (71.31 mm3) and heat resistance index (162.1°C) were synchronic‐lifting when compared with the GO/NR composites. The results demonstrated that obtained GO‐MMI/NR composites owned the promising application for the industrial‐scale green tires.
Multifunctional properties optimization and stimuli‐responsivity of shape memory polymeric nanoarchitectures and applications
Authors: Idumah Christopher Igwe 
Published: May 2023

AbstractAs a result of nanotechnological advancement, parameters inducing flaws in shape memory polymers (SMP), such as weak mechanical properties, low electrical, and thermal conductivities, and so on, were mitigated through the inclusion of a versatile range of nanomaterials such as montmorillonites, carbon nanotubes, graphene and derivatives, cellulose nanocrystals, carbon nanofibers, and so on, thereby forming shape memory polymeric nanoarchitectures (SMPNs). Hence, this work elucidates most recently emerging advancements on multifunctional SMPNs filled by differing nanoparticulates. Varying multifunctional SMPNs exhibit responsivity to varying forms of stimulation strategies, including thermal responsivity, electroactivated, alternating magnetic field responsivity, light sensitivity, and water induced SMPs. Therefore, this article presents very recently emerging advancements in the construction, characterization, properties, and multifunctional applications of stimuli‐responsive SMPNs, with special emphasis on functional and stimuli‐responsive SMPNs. Furthermore, important functions of SMPNs such as stimuli‐memory effect and self‐mending abilities, as well as prospective strategies for future progress of these materials are highlighted.

AbstractObjectiveSurvivorship guidelines recommend screening for depression and anxiety in young adult cancer survivors (YACS), but research validating measures in this population is limited. The current study aimed to examine use of the Primary Care Evaluation of Mental Disorders (PRIME‐MD) to screen for depression and anxiety in YACS.Methods249 YACS (aged 18–40, 50% male) completed PRIME‐MD via Telephone Automated Computer Assisted Structured Interview and the Structured Clinical Interview for the DSM‐IV (SCID) via in‐person interview. SCID responses were scored to identify depressive and anxiety symptoms and diagnoses. PRIME‐MD was scored to identify YACS reaching the symptom threshold (≥1 depressive or anxiety symptom) and diagnostic threshold for depressive or anxiety disorder. ROC analyses evaluated concordance of the PRIME‐MD with the SCID.ResultsThe PRIME‐MD depressive symptom threshold had excellent discrimination compared to SCID depressive diagnosis (AUC = 0.83) with high sensitivity (86%) and specificity (81%). Similarly, the PRIME‐MD depressive diagnosis threshold had excellent discrimination compared to SCID depressive diagnosis (AUC = 0.86) as well as high sensitivity (86%) and specificity (86%). No PRIME‐MD threshold met sensitivity (≥0.85) and specificity (≥0.75) criteria for identifying SCID depressive symptoms, anxiety disorders, or anxiety symptoms.ConclusionsPRIME‐MD has potential utility as a screening measure of depressive disorders in YACS. The PRIME‐MD depressive symptom threshold may be particularly useful in survivorship clinics as it requires only two items be administered. However, PRIME‐MD does not meet study criteria for a standalone screen for anxiety disorders, anxiety symptoms, or depressive symptoms in YACS.

Authors: Bao Wenhui , Ai Jun 
Published: May 2023

AbstractIn this work, silver nanoparticles are synthesized using a simple and sensitive method by using double‐stranded DNA (dsDNA‐Ag NPs) as a template. The prepared dsDNA‐Ag NPs are characterized by fluorescence spectroscopy analysis, X‐ray photoelectron spectroscopy analysis, and transmission electron microscopy analysis. The excitation wavelength of the prepared silver nanoparticles is 295 nm, the emission wavelength is 377 nm, the average particle size is 11.2 nm, and the dispersion is uniform with pleasurable stability. The nanomaterials are used as fluorescent probes to detect glutathione (GSH). After adding glutathione to the dsDNA‐Ag NPs fluorescent probes, the fluorescence of dsDNA‐Ag NPs is burst due to electron transfer and SAg bond generation, and the linear range of detection concentration is 0–90 mm with a detection limit of 0.37 mm.

AbstractBackgroundBilirubin is a potent antioxidant and anti‐inflammatory molecule that has been shown to ameliorate airway inflammation. We aimed to study whether serum bilirubin is protective and can predict the development of subsequent recurrent wheezing in infants with severe respiratory syncytial virus (RSV) bronchiolitis.MethodsThe medical records of 188 infants who were hospitalized during an initial episode of severe RSV bronchiolitis at 6 months of age or less were retrospectively reviewed. Our main outcome of interest was the development of subsequent recurrent wheezing by the age of 3 years. Each infant's serum bilirubin concentration was extracted from their blood biochemical results.ResultsSeventy‐one (37.8%) infants developed recurrent wheezing by the age of 3 and 117 (62.2%) did not. The serum total bilirubin, unconjugated bilirubin, and conjugated bilirubin levels at hospital admission were lower in infants who developed recurrent wheezing as compared to those who did not (p ＜ 0.001). The area under the receiver‐operating characteristic curve of serum total bilirubin, unconjugated bilirubin, and conjugated bilirubin for the prediction of subsequent recurrent wheezing were 0.71 (95% confidence interval [CI], 0.64–0.78), 0.70 (95% CI, 0.63–0.78), and 0.67 (95% CI, 0.59–0.75), respectively. Higher admission serum total bilirubin levels were independently associated with a lower risk of development of subsequent recurrent wheezing (adjusted OR 0.17, p ＜ 0.001).ConclusionDuring the first episode of severe RSV bronchiolitis in infants <6 months of age, moderately higher levels of serum bilirubin are associated with a reduced risk of developing subsequent recurrent wheezing by 3 years of age.

AbstractRAF1 (c‐raf) has been known as an important tumor‐promoter in many cancers. However, the regulatory mechanisms affecting RAF1 expressions are rarely reported. This study aimed to predict the candidate miRNAs of RAF1 gene and verify their functions in the progression of lung cancer. The expression of miR‐643 was detected by reverse transcription polymerase chain reaction (RT‐PCR). A dual‐luciferase report system was used to verify the relationship between miR‐643 and RAF1. RT‐PCR and Western blot were used to analyze the regulatory relationship between miR‐643 and RAF1. Transwell chamber, scratch, and monoclonal tests showed that miR‐643 affected the proliferation, migration, and radiosensitivity of H1299 and A549 cells by targeting the RAF1 gene. The expression of miR‐643 in lung cancer cells was lower than that in the bronchial epithelioid cells (CRL‐2741), and luciferase reporter experiment confirmed that miR‐643 targeted RAF1. MiR‐643 overexpression decreased the RAF1 expression, thereby decreasing cell migration, proliferation, and radiation resistance through the AKT/nuclear factor‐κB pathway. miR‐643 in lung cancer cells could inhibit cell proliferation, invasion, and metastasis and increase the radiosensitivity by downregulating RAF1.

Published: May 2023

AbstractAirway complications post lung transplant including ischaemia and dehiscence have a significant associated mortality (2%–4%) and morbidity. We describe a case of a 22‐year‐old female who developed significant bilateral anastomotic dehiscence with severe ischaemia following a bilateral single sequential lung transplant (BSSLTx). Following an intensive antimicrobial regimen, judicious bronchoscopic surveillance, and a prolonged inpatient stay, the dehiscence resolved without requiring further surgical intervention. Our case highlights a space in the literature for further research with regard to airway complications post‐lung transplant and their management.

AbstractBackgroundThe spontaneous rupture of hepatocellular carcinoma (HCC) is a rare complication. The management of this complication needs a stepwise, multidisciplinary approach which considers first of all clinical conditions of the patient and also the possibility of the best curative treatment.MethodsWe report our experience of an emergency robotic liver resection for a ruptured HCC in an elderly patient. Minimally invasive liver resection is currently recognised as a safe and feasible approach to the treatment of HCC in elderly patients.ResultsOur patient presented haemodynamic stability, which allows us to perform a robotic resection of segment 3. To our knowledge, this is the first report of the application of a robotic platform in an emergency setting for liver resection.ConclusionsRupture of HCC is an uncommon complication, burdened by a high rate of mortality. Its management still remains controversial. Treatment should be individualised taking into consideration the clinical status of the patient, tumour features and possibility of centre therapeutic strategy.

Published: May 2023

AbstractHigh‐efficiency and low‐cost bifunctional electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), as well as gel electrolytes with high thermal and mechanical adaptability are required for the development of flexible batteries. Herein, abundant Setaria Viridis (SV) biomass is selected as the precursor to prepare porous N‐doped carbon tubes with high specific surface area and the 900 °C calcination product of SV (SV‐900) shows the optimum ORR/OER activities with a small EOER–EORR of 0.734 V. Meanwhile, a new multifunctional gel electrolyte named C20E2G5 is prepared using cellulose extracted from another widely distributed biomass named flax as the skeleton, epichlorohydrin as the cross‐linker and glycerol as the antifreezing agent. C20E2G5 possesses high ionic conductivity from −40 to + 60 °C, excellent tensile and compressive resistance, high adhesion, strong freezing and heat resistance. Moreover, the symmetrical cell assembled with C20E2G5 can significantly inhibit Zn dendrite growth. Finally, flexible solid‐state Zn–air batteries assembled with SV‐900 and C20E2G5 show high open circuit voltage, large energy density, and long‐term operation stability between −40 and + 60 °C. This biomass‐based approach is generic and can be used for the development of diverse next‐generation electrochemical energy conversion and storage devices.

Published: May 2023

AbstractThe management of existing structures is raising a number of pertinent questions to the owners and engineers. Many structures built more than 50 years ago (even those built hundreds of years ago) usually no longer comply with safety requirements of current codes, which are typically addressed in new structures. This is not necessarily only caused by a poor original design or degradation with time, but it may be, for example, the consequence of increase in actions, reducing the level of reliability of a structure. This paper focuses on strategies to be adopted for existing structures which do not comply with code requirements for new constructions (e.g., to repair, to demolish, to rebuild, etc.) on the basis of a more holistic approach that includes economic, social, and environmental considerations. To that aim, first, a brief review of the background concepts on the reliability of structures is presented, highlighting the differences for new and existing structures. Following this analysis, suitable values for the reliability index (including sustainability considerations) are proposed, as well as tailored maintenance strategies. Finally, the paper presents a case study based on a real project to emphasize the benefits of adopting such a holistic perspective.

Published: May 2023

AbstractElectrocatalytic oxygen reduction reaction (ORR) to prepare H2O2 in acidic medium has the advantages of green, safety, and portability, which shows broad development prospects. However, it still suffers from low catalyst activity, insufficient selectivity, and high cost. Herein, Pt1/CoSe2 with ultralow 0.01 wt.% Pt atomic distribution was synthesized by a simple hydrothermal method. The Pt1/CoSe2 with ultralow Pt content exhibits high activity, high selectivity, and long‐term stability for ORR to H2O2 in O2‐saturated 0.1 M HClO4. The onset potential is as low as 0.75 V versus reversible hydrogen electrode (RHE), H2O2 selectivity is as high as 84% (0.4 V vs. RHE), and the electron transfer number is 2.3 (0.4 V vs. RHE). Moreover, the hydrogen peroxide yield using the flow cell testing is 110.02 mmol gcat.−1 h−1 with high Faradaic efficiency of 78% (0 V vs. RHE) at 0.1 M HClO4, and the catalyst did not deactivate significantly after 60 h stability testing. Mechanistic studies and in situ X‐ray photoelectron spectroscopy characterization confirm that the ultralow Pt content on CoSe2 can effectively regulate the electronic structure of Co as the real active site around the Pt site, which gives a suitable ∆dp value (the difference between the d‐band center of the active metal site and the p‐band center of the terminal oxygen in *OOH), provides an ideal *OOH binding energy, and inhibits the O–O bond breakage. This work successfully improves the intrinsic activity of the Co active sites around Pt in Pt1/CoSe2 for acidic ORR to H2O2 by constructing ultralow‐content Pt single atom.

AbstractPolyaniline (PANI) has piqued the interest of nanotechnology researchers due to its potential as an electrode material for supercapacitors. Despite its ease of synthesis and ability to be doped with a wide range of materials, PANI′s poor mechanical properties have limited its use in practical applications. To address this issue, researchers investigated using PANI composites with materials with highly specific surface areas, active sites, porous architectures, and high conductivity. The resulting composite materials have improved energy storage performance, making them promising electrode materials for supercapacitors. Here, we provide an overview of recent developments in PANI‐based supercapacitors, focusing on using electrochemically active carbon and redox‐active materials as composites. We discuss challenges and opportunities of synthesizing PANI‐based composites for supercapacitor applications. Furthermore, we provide theoretical insights into the electrical properties of PANI composites and their potential as active electrode materials. The need for this review stems from the growing interest in PANI‐based composites to improve supercapacitor performance. By examining recent progress in this field, we provide a comprehensive overview of the current state‐of‐the‐art and potential of PANI‐based composites for supercapacitor applications. This review adds value by highlighting challenges and opportunities associated with synthesizing and utilizing PANI‐based composites, thereby guiding future research directions.
Global patterns of water‐driven human migration
Authors: Xu Li , Famiglietti James S. 
Published: May 2023

AbstractEnvironmental change is growingly reported as an important driver of human migration. Among all environmental variables, water crises are the most critical factors. To date, patterns of interconnections between changes in water and migration are not yet clearly understood. Here, we explore these patterns through a systematic review that combined a quantitative text‐mining approach with qualitative thematic analysis. Our results generally concur with those of previous studies, which found that water‐driven migration usually occurs internally and that the population in low‐ and middle‐income countries and in dry regions are the most vulnerable and more likely to migrate or be displaced in the face of water‐related events. However, our causal network analysis highlights that water is not the only reason for migration: Its related problems could be major triggers driving people‐at‐risk to leave their original place. Based on observed evidence, water‐driven migration can be generally divided into four patterns: variability in water quantity, damaging water hazards and extremes, physical disturbances to water systems, and water pollution. These patterns are not independent but interconnected through multifaceted factors affecting people's livelihoods and their decisions to migrate. Understanding water‐migration dynamics requires systematic thinking of the interconnections between changes in water and in migration patterns, the investigation of interactions between fast and slow water variables and their dynamic link to other socioeconomic variables, an integrated water‐migration database to help identify early‐warning signals of damaging water hazards that may result in undesirable migration, and targeted water policies that focus on building the resilience of vulnerable regions and population to climate change.This article is categorized under:
