Published: December 2022

Comprehensive SummaryFour heterometallic rare earth(III)‐cobalt(II) complexes (rare earth = Y (1), Sm (2), Nd (3), La (4)) stabilized by an o‐phenylenediamine‐bridged tris(phenolato) ligand (L) have been synthesized and characterized. In these tetranuclear complexes, one polydentate L coordinates to one rare earth(III) ion, and one cobalt(II) ion, respectively, while two rare earth ions are bridged by four acetate groups. These complexes were applied in the copolymerization of cyclohexene oxide and CO2, which showed good activity (TON up to 440) and high poly(cyclohexene carbonate) selectivity (>99%). Kinetic studies determined the equation as rate = k[CHO]1[CO2]0[initiator]1, which proves a first‐order dependence on initiator concentrations and implies a synergistic mechanism with rare earth and cobalt ions cooperating in epoxide ring‐opening and chain propagation.

Published: December 2022

AbstractCoSn/Co3Sn2@C with nanocages structure is obtained via a facile coprecipitation method with polydopamine coating followed by an annealing procedure. Due to the uniform nanocages structure, CoSn/Co3Sn2@C moderates the volume fluctuation, ensures good infiltration with electrolyte, and provides more pathways for ions/electrons transport. Moreover, the introduction of carbon inhibits the agglomeration of Sn0 nanoparticles, improves electronic conductivity, and offers a buffer matrix to protect the nanocage structure from destructing. As lithium‐ion batteries (LIBs) anode, this CoSn/Co3Sn2@C anode possesses 622.3 mAh g−1 after 300 cycles at 200 mA g−1 and 571.2 mAh g−1 for another 1600 cycles at 1000 mA g−1. CoSn/Co3Sn2@C can maintain a capacity of 791.1, 748.3, 678.4, 569.8, 461.0, and 367.0 mAh g−1 at 65, 130, 0260, 650, 1300, and 2600 mA g−1, respectively. For sodium‐ion batteries (SIBs), the CoSn/Co3Sn2@C can attain a specific capacity of 290.2, 246.6, 205.1, 166.0, 142.3, and 124.1 mAh g−1 at 80, 160, 320, 800, 1600, and 3200 mA g−1, respectively. CoSn/Co3Sn2@C anode earns 171.9 mAh g−1 after 150 cycles at 1000 mA g−1. This design of strategy provides ideas for the fabrication of porous anode materials and will promote the development of LIBs and SIBs.

Published: December 2022

SummaryNowadays, data centers and servers are rising in size by order of magnitude due to increasing CCTV footages. Therefore, load balancing (LB) becomes a primary concern in scalable computing system involves mobile edge cloud computing environment. In mobile edge cloud computing system, a mobile user offloading their task to neighboring edge server for supporting realistic application. But while user is situated in a hot spot, various edge servers are over‐loaded as a result of sudden offloading task from the mobile user. The LB process can be considered as an optimization problem, which can be resolved by the use of metaheuristic optimization algorithms. This article introduces an Improved Search and Rescue Optimization based LB Scheme for Edge Computing Environment (ISROLBS‐ECE). The presented ISROLBS‐ECE technique majorly concentrates on the distribution of offloading tasks to neighboring edge servers effectively. In addition, the ISROLBS‐ECE technique involves the hybridization of chaotic concept into the conventional search and rescue optimization (SRO) approach. In the ISROLBS‐ECE technique, the moderately lightest and task arrival nodes are employed as target node for allocating new task whereas rest of the nodes are not provisionally allocated tasks to accomplish dynamic balancing of the network. The experimental validation of the ISROLBS‐ECE technique is tested and the outcomes are investigated under various aspects. The comparative study shows the better performance of the ISROLBS‐ECE approach over other recent techniques.

AbstractBackgroundWomen are likely to suffer from maternal depression due to childbirth difficulties and parenting responsibilities, leading to long‐term negative consequences on their children and families. British mothers of African/Caribbean origin uptake of mental healthcare is low due to the lack of access to culturally appropriate care.MethodsA mixed‐methods randomized controlled feasibility trial was adopted to test the appropriateness and acceptability of Learning Through Play plus Culturally adapted Cognitive Behaviour Therapy (LTP+CaCBT) for treating maternal depression compared with Psychoeducation (PE). Mothers (N = 26) aged 20–55 were screened for depression using the Patient Health Questionnaire (PHQ‐9). Those who scored >5 on PHQ‐9 were further interviewed using the Revised Clinical Interview Schedule to confirm the diagnosis and randomized into LTP+CaCBT (n = 13) or PE (n = 13) groups. Assessments were taken at baseline, end of the intervention at 3‐ and 6‐months post‐randomization. N = 2 focus groups (LTP+CaCBT, n = 12; PE, n = 7) and N = 8 individual interviews were conducted (LTP+CaCBT, n = 4; PE, n = 4).ResultsThe LTP+CaCBT group showed higher acceptability, feasibility and satisfaction levels than the PE group. Participants experienced the intervention as beneficial to their parenting skills with reduced depression and anxiety in the LTP+CaCBT compared to the PE group.ConclusionsThis is the first feasibility trial of an integrated online parenting intervention for British African and Caribbean mothers. The results indicated that culturally adapted LTP+CaCBT is acceptable and feasible. There is a need to study the clinical and cost‐effectiveness of LTP+CaCBT in an appropriately powered randomized control trial and include the child's outcomes.Trial registration. www.ClinicalTrials.gov (no.

Toward eDNA‐based bioassessment of freshwater reservoirs with small volumes of water: Robust molecular protocols
Authors: Loh Rebecca K. , Kutty Sujatha N. , Yeo Darren C. J. , Meier Rudolf 
Published: December 2022

AbstractBioassessment of freshwater quality with eDNA is a powerful alternative to traditional methods involving collecting, sorting, and identifying metazoan taxa with morphology (e.g., macroinvertebrates). Particularly attractive for routine monitoring would be an eDNA method that uses a remote‐controlled boat for collecting small volumes of water without filtration in order to simplify sampling. Such a method would not likely capture eDNA signals for all metazoan species, but may nevertheless allow for cost‐effective, and frequent monitoring of water quality, which is important for tropical waterbodies that require year‐round surveillance. We here optimize a molecular protocol for capturing metazoan signatures based on eDNA obtained from 15 ml of water. To test the robustness of the method, we used samples from two tropical reservoirs with known differences in water quality to optimize molecular procedures so that they yield repeatable results. Each reservoir was sampled at three sites (“biological replicates”) and each water sample was subsampled twice before extracting the eDNA using ethanol precipitation for both subsamples (“technical replicates”). We then tested how much DNA (0.1 ng to 15 ng) and how many PCR cycles (25 or 35) minimized the variance of the metazoan eDNA signal between biological and technical replicates. For this purpose, we amplified a 313 bp COI minibarcode using a universal metazoan primer pair. We found that regardless of template amounts or PCR cycle numbers, the eDNA signatures for both reservoirs were distinct because only 17 of 59 mOTUs (mainly planktonic crustaceans and rotifers) were shared. We also found that template amounts between 0.5 and 15 ng yielded overall similar results, but the use of 35 PCR cycles significantly depressed the number of detected species (p‐value < 0.05). Fortunately, the differences between the detected metazoan community of the reservoirs were so strong that all biological and technical replicates could be assigned unambiguously to their source reservoir although the variance between technical replicates remained high for all PCR experiments (Bray‐Curtis dissimilarity: 5%–20%; Jaccard distance: 10%–40%).

AbstractHarvesting hot carriers (HCs) before thermalizing to the perovskite crystal lattice is very promising for advancing the efficiency of perovskite solar cells (PSCs) towards the Shockley–Queisser limit. Thus, it is very crucial to slow down the HCs cooling process in lead halide perovskites. Herein, we investigated the HCs cooling dynamics of perovskite films in the presence of an organic small molecule, 2,5‐thiophenedicarboxylic acid (TDCA). We found that adding TDCA into perovskite films can efficiently retard HCs cooling process, which favors extracting the excess energies of HCs through carrier transport layers and reducing electron–hole recombination, resulting in enhanced performance in TDCA modified device. Moreover, TDCA can effectively passivate unsaturated Pb2+ defects of perovskite films while promoting a preferential crystal orientation. Consequently, the PSCs efficiency is enhanced to 22.85% (TDCA) from 19.96% (control). These findings provide important insight for understanding HCs transfer dynamics and developing next‐generation perovskite‐based HCs optoelectronic devices.image

AbstractGinger and its derivatives have been shown to be effective in the prevention and treatment of cancer. We undertook a systematic review to answer the question of whether ginger has a role in modifying the biomarkers of cancer in cell culture conditions and on colorectal cancer in randomized clinical trials. We performed a comprehensive search of the literature from Scopus, Embase, Web of Science, PubMed, Cochrane central register of controlled trials, and Cochrane database of systematic reviews. At first, all 12 papers studied the effect of ginger or its derivatives on cell culture conditions. The results of cell culture studies show that ginger has a powerful role in inducing apoptosis. In the second part, five studies of clinical trials were analyzed. By analyzing antitumor markers of clinical trials, ginger increased some anticancer markers but performed poorly in inducing some anticancer markers. This systematic review showed that the consumption of ginger extract has the potential to prevent and treat colorectal cancer but this ability is weak.
Grading bias and young adult mental health

Published: December 2022

AbstractWe study exposure to grading bias and provide novel evidence of its impact on mental health. Grading bias, which we interpret as over‐grading, is constructed as the residual of final upper secondary school grades having controlled for results in a standardized test, itself not subject to grading leniency. Grading bias is further isolated by considering only within‐school variation in over‐grading and controlling for prior grades and school production. Using Swedish individual‐level register data for individuals graduating from upper secondary school in the years 2001–2004, we show that over‐grading has substantial significant protective impacts on the mental health of young adults, but only among female students. That grades themselves, independent of knowledge, substantially impact the production of health highlights an important health production mechanism, and implies that any changes to the design of grading systems must consider these wider health implications.
Multisource remote sensing data facilitate ecohydrological simulations without runoff calibration
Authors: Yang Dong , Xu Xianli , Scanlon Bridget R. 
Published: December 2022

AbstractObserved runoff is typically the only variable applied to calibrate ecohydrological models, which can simulate runoff well but cannot guarantee reliable reproduction of other hydrological components (e.g., evapotranspiration (ET) and total terrestrial water storage change (TWSC)). This study explores the potential of estimating hydrological components (runoff, ET, TWSC, groundwater, and root‐zone water storage.) using a conceptual model driven and calibrated by multisource remote sensing data only. The performances of the model were evaluated in 13 catchments with different geological, climatic and vegetation conditions. Results show that the model was encouraging in simulating monthly runoff (median KGE, 0.71; RMSE, 19.4 mm/mon), ET (median KGE, 0.86; RMSE, 9.0 mm/mon), and TWSC (median KGE, 0.58; RMSE, 26.6 mm/mon). The good positive correlation between root‐zone water storage and gross primary productivity also indicates the effectiveness of the model in simulating root‐zone water storage. This study offers new prospects for estimating key ecohydrological components precisely, especially in catchments that are difficult to monitor (e.g., karst regions) and catchments with limited observation data (e.g., ungauged regions).

Published: December 2022

AbstractRecent efforts have focused on preparing drug‐loaded hydrogel for wound healing. In order to obtain an ideal hydrogel dressing for skin wound repair, a carboxymethyl chitosan‐gelatin hydrogel was prepared for co‐delivery of SP (substance P) and DMOG (dimethyloxallyl glycine) by a chemical cross‐linking method using genipin as the cross‐linking agent. The synthesized hydrogels have good biocompatibility and physicochemical properties due to the low toxicity of the hydrogel material. The three‐dimensional network structure of the hydrogels supports cell migration and proliferation, and the combination of SP and DMOG drugs exhibited strong effects on cell proliferation. Moreover, the co‐loaded drug hydrogels could significantly promote wound healing in vivo, and provide a potential hydrogel for wound healing.
An in‐silico investigation of fluoride ions impact on pancreatic lipase

Published: December 2022

AbstractFluorine is a halogen beneficial to teeth and bones at a lower concentration. But in excess, it is a toxin and causes adverse effects. Fluoride is toxic to enzymes generally when it inhibits the enzyme activity involved in metabolic pathways. Here we study invitro and invivo findings on the interaction of fluoride on the enzymes Aconitase, Adenylyl cyclase, Arginase, Cytochrome‐c‐oxidase, Glucose‐6‐phosphatase, Protein phosphatase, Succinate dehydrogenase from liver and lipase from pancreas by using molecular docking and simulations to gain insights into the mechanism by which fluoride modifies the activity of pancreatic lipase. our molecular modeling and docking studies identified that lipase is the most strongly inhibited enzyme compared to other enzymes mentioned above with −0.42 Kcal/mol binding energy and 495.78 milli molar of predicted IC50 value with interaction with Phe227 residue. To further validate this, we have taken the lipase enzyme in presence of fluoride ions for molecular dynamic simulations of 100 ns. To analyze the impact of fluoride ions on the lipase dynamics, two different simulations of 100 ns each were performed. In one simulation, we have simulated lipase in its apo form in the aqueous environment without any fluoride ions and in another simulation lipase in its apo form was kept in the presence of randomly placed fluoride ions countered with sodium ions to maintain the pH as neutral. The simulation analysis revealed that major fluctuations in lipase was observed between 230 and 300 residues in presence of fluoride ions. Interestingly, this is the exact location of the “lid” like acting loop of residues responsible for the inward/outward movement of the substrate to lipase catalytically active site containing catalytic triad of residues Leu153, His263, and Pro177. His263 residue random flip is believed to be the critical incident that causes the substrate's inward/outward movement at the catalytically active site coordinated by “lid” opening, providing enough space for the substrate.

ObjectiveThis study aimed to investigate the prognostic factors and treatment outcomes in patients with the external auditory canal (EAC) squamous cell carcinoma (SCC).MethodsAll patients diagnosed with EAC SCC and treated with curative intent at a single tertiary institution were retrospectively reviewed over a 22‐year period. Treatment modalities included surgery with adjuvant treatment or definitive radiotherapy. The primary endpoints were overall survival (OS) and disease‐specific survival (DSS).ResultsThere were 51 patients in our cohort. The 5‐year OS and DSS were 64.0% ± 7.0% and 72.0% ± 7.0% respectively. Patients in the surgical arm and RT arm showed no significant difference in OS, DSS, and LRFS (p = 0.075, 0.062, 0.058 respectively). Compared to other routes of spread within the temporal bone, pattern of posterior disease invasion (involving mastoid/sigmoid sinus) showed poorer OS and DSS on multivariate analysis (hazard ratio, HR4.34 and 5.88; p = 0.006 and 0.009). On multivariate analysis, the following factors were independently prognostic of poorer OS and DSS: Previous radiotherapy (HR 3.29 and 4.81, p = 0.021 and p = 0.029); Presence of facial nerve palsy (HR 3.80 and 7.63, p = 0.013 and p = 0.003); Posterior pattern of invasion (HR4.05 and 3.59, p = 0.013 and p = 0.043). Advanced modified Pittsburgh stage was not predictive of poor OS and DSS (HR1.17 and 1.17 E+5, p = 0.786 and p = 0.961).ConclusionPresence of previous radiotherapy, facial nerve palsy and posterior pattern of disease invasion were independent prognostic factors of poorer survival in patients with EAC SCC.Level of Evidence4 Laryngoscope, 133:2203–2210, 2023

AbstractAluminum (Al) toxicity is one of the most serious hazards of soil acidification, which limits root formation and hinders crop growth. Soil acidification in orchards has been widely reported. However, there is little information about the effect of Al3+ on citrus roots in acidified red soil. Taking pomelo (Citrus grandis), the main citrus variety in Southeast China, as an example, soil surveys were conducted to analyze the status and characteristics of acidification in pomelo orchards. Subsequently, we explored whether optimized fertilization and liming can effectively reduce Al toxicity in roots and increase yield by three treatments, including farmer fertilization practice (FFP), NPK optimization (OPT), and OPT combined with lime (OPT+L). The results showed that (1) rapid soil acidification occurred in pomelo orchards in the past 40 years (with a decrease of 0.81 units). The severity of soil acidification increases with orchard age. In addition, the soil pH and base saturation (BS) at the drip line (DL; i.e., fertilization site) were the lowest, while the concentration of exchangeable acid (Ex.Acid) and exchangeable Al (Ex.Al), and the ratio of Ex.Al to cation exchange capacity (Ex.Al%) was highest compared to other locations away from DL. Random forest analysis indicated Ex.Al was the most important factor to reflect soil acidification. (2) Under the OPT+L treatment, the concentrations of soil Ex.Acid and Ex.Al decreased, and BS increased, which markedly reduced the Al3+ concentration in the roots and promoted root growth. OPT+L significantly decreased the Al concentrations in soils (by 71.3%) and roots (by 47.8%) but increased root activity, root length, root tips and root surface area by 119.2%, 80.3%, 124.6% and 136.6%, respectively. In addition, structural equation modeling further proved that increasing soil pH and BS while decreasing Ex.Al was beneficial to citrus production in acidic soil, and optimized fertilization and lime application are necessary.
DECODING THE DNA OF SUSTAINABLE LEADERS
Authors: Murphy Clarke 
Published: December 2022

AbstractThe author details his project of interviewing fellow Chief Executive Officers/CEOs about one of today's most important topics, sustainability. How can executives lead their organizations to sustainability? This project began with “a career‐changing conversation I had at the World Economic Forum's Davos 2019 with Lise Kingo, then president of the United Nations Global Compact, and a pioneer of the “triple bottom line”—balancing economic, social and environmental priorities.” He notes that “in 2000, more than 10,000 companies including my own, Russell Reynolds Associates, pledged to help meet the United Nations’ 17 Sustainable Development Goals by 2030.” But nearly 20 years after that pledge was made, things seemed stalled. At the same time, some leaders seemed to be doing well. He and Kingo “developed a blueprint of Sustainable Leadership, which set out the specific mindset and skills business leaders would need to move the dial on sustainability—everything from having an almost instinctive understanding of the role their organization plays in society, to working hand‐in‐hand with stakeholders, and applying a disruptive mindset to everything they do.” He also describes “moonshotters,” leaders who “are ready to commit to bold action without even necessarily knowing what the exact solution is or how they will get there.”
