Impact of Light on Coexistence of Memresistance, Meminductance, and Memcapacitance (MEMRIC) in Nanostructured Copper Oxide (CuO) Based Random Access Memory Devices
Authors: Prakash Chandra , Yadav Ankit K. , Dixit Ambesh 
Published: September 2024

AbstractWe demonstrated the coexistence of memresistance, memcapacitance, and meminductance non‐volatile bipolar analog resistive switching in Cu (top electrode)/CuO (active layer)/SS (bottom electrode) memory devices with and without presence of the light. The onset of memcapacitance and meminductance is noticed from the pinched‐shaped characteristics in the first and third quadrants. The variation in the scan rate also impacts the coexistence characteristics by shifting the intercept point for low resistance (LRS) and high resistance (HRS) states in positive and negative biasing voltages. The durability and retention are measured over a period of 150 cycles and 1500 s with and without light illumination. The slopes for the Weibull cumulative distribution plot for set/reset state with and without light are 106.80/114.23 and 70.21/102.25, respectively, suggesting that the stability of the device increases with light illumination. Interestingly, the memcapacitance disappears after 600 cycles and after 60
. The double logarithmic I−V characteristics suggest the trap‐assisted conduction (higher slope >2) in the higher external electric field, and Ohmic behavior in the lower applied field region. Thus, the present study provides a way for low‐power electronics and photoresistors together with memresistance, memcapacitance, and meminductance, simultaneously, i. e., MEMRIC in a single device.

AbstractGlobally, we are in the midst of a biodiversity crisis and megadiverse countries become key targets for conservation. South Africa, the only country in the world hosting three biodiversity hotspots within its borders, harbours a tremendous diversity of at‐risk species deserving to be protected. However, the lengthy risk assessment process and the lack of required data to complete assessments is a serious limitation to conservation since several species may slide into extinction while awaiting risk assessment. Here, we employed a deep neural network model integrating species climatic and geographic features to predict the conservation status of 116 unassessed plant species. Our analysis involved in total of 1072 plant species and 96,938 occurrence points. The best‐performing model exhibits high accuracy, reaching up to 83.6% at the binary classification and 56.8% at the detailed classification. Our best‐performing model at the binary classification predicts that 32% (25 species) and 8% (3 species) of Data Deficient and Not‐Evaluated species respectively, are likely threatened, amounting to a proportion of 24.1% of unassessed species facing a risk of extinction. Interestingly, all unassessed species predicted to be threatened are in protected areas, revealing the effectiveness of South Africa's network of protected areas in conservation, although these likely threatened species are more abundant outside protected areas. Considering the limitation in assessing only species with available data, there remains a possibility of a higher proportion of unassessed species being imperilled.

AbstractThe spatial distribution of biological communities may be regulated by environmental and spatial processes, and the intensity of these processes depend on the species characteristics, spatial heterogeneity and spatial extent. We investigated the relationship between the non‐migratory fish metacommunity with environmental and spatial variables using the variance partitioning procedure. We used data from lakes of four Neotropical floodplains: Amazon, Araguaia, Pantanal and Paraná. We hypothesised that the processes that drive the spatial distribution of non‐migratory fish in floodplain systems depend on connectivity driven by flood pulse. We predict that spatial variables are less important to explaining the fish community structures during rainy periods when there is no dispersal limitation. In contrast, environmental variables influence these structures during rainy and dry periods. During dry periods, metacommunities depend on species' dispersal abilities, but during rainy and dry periods, spatial distribution depends on the environmental filters selected by each species. For most of the environmental variables, it was possible to observe more similarity in the rainy period. Our results showed different patterns of fish communities for the lakes of the four floodplains systems, which led us to reject our hypothesis. Non‐migratory fish remain in their natal environment and perform only small lateral movements. In this scenario, we found a little influence from spatial variables in both periods and a great contribution of environmental variables for Amazon (16%) and Pantanal (32%) floodplains in structuring fishes' distribution in the rainy period.

Published: September 2024

AbstractThe pathogenesis of Parkinson's disease (PD) is closely related to the gut microbiota, and microecological therapies based on gut probiotics have received widespread attention, among which Bifidobacterium has been demonstrated to have a potential neuroprotective effect, but specific mechanisms have been lacking in the investigation. Here, we show that Bifidobacterium longum subsp. longum CCFM1029 significantly inhibited LPS‐induced inflammatory responses in microglia and alleviated 1‐methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine (MPTP)‐induced motor dysfunction, dopaminergic neuronal damage, and neuroinflammation in PD mice. Subsequently, the mechanism of action of CCFM1029 in PD was systematically elucidated by the neurochemical and biochemical analysis in PD mice, together with microbiomic and metabolomic analysis. It was found that CCFM1029 intervention restores dysbiosis in the gut microbiota linked to PD and reverses alterations in microbial metabolites. We established the interactions among the gut microbiota, metabolites, and brain by integrating behavioral and neurophysiological data with changes in the composition of the gut microbiota and metabolomic characteristics. We found that CCFM1029 intervention increases levels of the beneficial gut microbial metabolites indole‐3‐acrylic acid and short‐chain fatty acid (acetic and butyric acid) and decreases levels of the neuroinflammation‐associated metabolite N‐acetylhistamine. To summarize, our findings suggest CCFM1029 as a novel dietary supplement can prevent and mitigate the progression of PD through the microbiota‐gut‐brain axis.

Published: September 2024

AbstractAimsEpidemiological and outcome studies on patients in Japan with heart failure (HF) categorized by left ventricular ejection fraction (LVEF) are currently limited. The aim of this non‐interventional database study was to provide further information on these patients.Methods and resultsAdministrative claims data and electronic medical records from hospitals participating in the Voluntary Hospitals in Japan (VHJ) organization were used. Patients hospitalized with a primary diagnosis of HF between 1 April 2017 and 30 March 2020 were categorized by baseline LVEF on echocardiogram: HF with reduced EF (HFrEF, LVEF <40%); HF with preserved EF (HFpEF, LVEF ≥50%); and HF with mildly reduced EF (HFmrEF, 40% to <50% LVEF). Patients were evaluated for baseline characteristics, pre‐admission diagnosis, prescription drugs, length of hospitalization, HF treatment cost, overall cost of hospitalization, and in‐hospital prescription. An exploratory analysis compared post‐hospitalization mortality and re‐hospitalization rates. In total, 10 646 hospitalized patients from 17 VHJ hospitals were enrolled. Of these, 7212 were included in the analysis set and categorized into HFpEF (3183, 44.1%), HFmrEF (1280, 17.7%), and HFrEF (2749, 38.1%) groups based on baseline LVEF. Beta‐blocker use increased during hospitalization, with a mean (95% confidence interval [CI]) of 23.3% (22.3–24.3) of patients receiving these agents before admission versus 69.4% (68.3–70.5) at discharge. Administration of diuretics, angiotensin converting enzyme (ACE) inhibitors, and angiotensin II receptor blockers (ARBs) showed a similar trend. Differences in treatments were observed between HF categories at discharge, with a higher proportion (95% CI) of ACE inhibitor use in the HFrEF group (40.6% [38.7–42.4]) versus HFmrEF (27.5% [25.1–30.0]) and HFpEF (20.6% [19.2–22.1]) groups (P < 0.0001), and more ARB use in the HFmrEF and HFpEF groups (32.5% [29.9–35.1] and 31.2% [29.6–32.9], respectively) versus HFrEF (25.1% [23.5–26.8]; P < 0.0001). Mean (standard deviation [SD]) length of hospitalization was 22.2 (23.3) days, and the median (interquartile range) was 17 (11‐25) days. Estimated average cost of HF treatment per patient during index hospitalization was 300 090 yen with HFrEF treatment costing the most. Average total healthcare expenditure during hospitalization was 1 225 650 yen per index hospitalization per patient, with HFrEF also the most expensive. During a mean (SD) observation period of 324 (304) days, ~21% of patients in each group required re‐hospitalization for HF, and 625 patients (8.7%) died.ConclusionsThe proportion of patients in each HF category was largely consistent with existing data. Discharge medications indicated high prescription of guideline‐directed therapy. This study provides real‐world data on patients with HF in Japan that can help inform future clinical decision‐making.

Published: September 2024

AbstractThis study successfully synthesized a new Metal‐Organic Framework (MOF) named CJLU−L2, which was constructed from phosphorus‐containing ligands and Co(II) ions. The structure revealed through single‐crystal X‐ray diffraction (SCXRD), features a double‐walled honeycomb‐shaped structure with a one‐dimensional channel of ~6.5 Å. According to the PLATON calculation, the pore volume per unit cell of CJLU−L2 was determined to be 6825.0 Å3, constituting 57.5 % of the total crystal volume (11874.9 Å3). The Brunauer‐Emmett‐Teller (BET) surface area of CJLU−L2 was determined to be 954 m2/g by N2 adsorption measurement at 77 K. The phase purity of CJLU−L2 was verified by powder X‐ray diffraction (PXRD) and infrared spectroscopy (IR), while its thermal stability was confirmed by thermogravimetric analysis (TGA). Hydrogen adsorption experiments demonstrate that CJLU−L2 exhibits a high hydrogen adsorption capacity, indicating significant potential for gas adsorption applications.
Age of the examiner and older people's memory performances: A test of the stereotype threat theory using variations on negative age stereotypes across 18 European countries
Authors: Heiser Neele H. , Desrichard Olivier 
Published: September 2024

AbstractThis study investigated whether the age of examiner effect, that is, the positive relation between cognitive performance of older people and age of their examiner, relies on stereotype threat. Data from the Survey of Health, Ageing and Retirement in Europe (SHARE), European Social Survey, European Statistical Office (Eurostat) and the United Nations Economic Commission for Europe were crossed. Older people from different countries were tested on verbal short‐ and long‐term recall components of memory, by examiners of different ages. Country‐specific indicators of negative age stereotypes, related to the stereotype threat mechanism, were used. We expected that the age of examiner effect would be stronger in countries with more negative age stereotypes. The results replicated the age of examiner effect, but contrary to our hypothesis, this effect was not moderated by countries’ indicators of negative age stereotypes. Negative age stereotypes across countries, such as experienced discrimination among older people, lack of active ageing index, unemployment ratio and perceived negative competence of older people decrease memory. The results are discussed in relation to stereotype threat theory.
A Study of Asymmetric Hyperbolic Heat Storage Unit
Authors: Luo Huanting , Du Wenjing , Wang Zhan 
Published: September 2024

ABSTRACTDue to the advantages of high energy density and constant temperature, phase change energy storage technology has attracted much attention in energy saving and efficient utilization of energy. In this paper, Fluent software is used to simulate and analyze the heat storage characteristics of six new thermal storage units: corrugated tube, hyperbolic‐shape, non‐hyperbolic‐shape, symmetric frustum‐shape, non‐frustum‐shape, and bow‐shape. The results show that the melting rate of the non‐hyperbolic‐shape phase change unit is significantly higher than that of the circular tube, the heat storage time is shortened by 22.52%, and Ra* reaches 0.0086. Second, the effects of the radius difference (δ) between the inlet and outlet of the non‐hyperbolic‐shape phase change unit and the asymmetric position (s) on the heat storage process are studied. The results show that when δ increases from 2 to 10 mm, the melting time of phase change material (PCM) is shortened by 22.89%, that is, the average heat transfer rate between PCM and heat transfer fluid increases with the increase of δ. On the other hand, the average heat storage rate of the heat storage unit decreases first and then increases with the increase of s. When δ = 10 mm, s = 35 mm is the best working condition, the average heat storage rate of the non‐hyperbolic‐shape thermal storage unit reaches 34.3 J/s. This study can provide new ideas and references for the optimization design of latent heat storage units and the progress of experiments.
Urban Lake Health Assessment Based on the Synergistic Perspective of Water Environment and Social Service Functions
Authors: Wang Xueyuan , Cheng Yuning 
Published: September 2024

AbstractUrban lakes serve as vital ecological and recreational anchors within built environments, essential for enhancing urban resilience. Evaluating lake health predominantly focuses on water quality, assessing indicators such as nutrient levels, toxicity, pH balance, and water clarity to monitor changes. This study proposes a comprehensive evaluation framework that systematically describes specific spatiotemporal manifestations and periodic exogenous regulation characteristics across five dimensions: physical structure, water quality, shoreline dynamics, external regulation, and social service. Furthermore, it introduces an urban lake health assessment model based on synergistic development to evaluate the integrated development and interaction between water environments and social services. This model is applied across urban lakes in various developmental stages in China. Key findings include: 1) Urban development often impacts lake health disparately, with varying degrees of synergy observed between water environments and social services across different urban lakes. However, shifts in urban ideologies and improvements in governance, along with protective policies and project implementations, have contributed to improving water quality to some extent. 2) Engineering interventions do not consistently correspond with improvements in water quality, and governance measures sometimes yield mixed outcomes, underscoring the necessity for systematic solutions to lake health. Restoring hydrological processes emerges as crucial for enhancing sustainability.

Published: September 2024

AbstractBackground and AimTaxi drivers play a significant role in urban mobility and safety as professional drivers. They typically have poor incomes, long work hours, lack of sleep, and high levels of stress, which increase the risk of physical and mental illnesses. The goal of this study was to explore the relationship between sleep disorders and depression among Tabriz metropolis taxi drivers.MethodsUsing the street intercept technique, a cross‐sectional study was conducted with the participation of 402 taxi drivers in Tabriz during January and March 2020. Data collection tools included the Pittsburgh Sleep Quality Index (PSQI) and Patient Health Questionnaire as well as demographic information. Twenty taxi stops were used as sampling sites, and the method used was random sampling based on the number of drivers at each stop. Statistical analysis was performed using Stata 13.ResultsThe majority of drivers worked an average of 6 days each week, with a mean tenure of 13.3 years. The sleep quality mean score for drivers was 5 (SD = 2.3). Approximately, 21% of them had sleep disorder (PSQI >6). Moderate depression was recognized in 13% of drivers and moderately severe depression has been found in 5% of them. Drivers were more likely to experience sleep disorders if they had mild (odds ratio [OR] = 3.9), moderate (OR = 16.4), or fairly severe depression symptoms (OR = 35.3). A seven times higher risk of depression was identified among drivers with sleep disorders.ConclusionIt might be contended that a mutual relationship has been found between sleep disorders and depression, and disregarding this will deteriorate sleep turbulences. Considering the pivotal role of taxi drivers in urban mobility, accommodating initiatives that give a break time for drivers and improve their mental health is recommended.

AbstractBackground and AimsEndocan is a marker of endothelial damage. Data regarding the association of this proteoglycan and acute respiratory distress syndrome (ARDS) is discrepant. Hence, this study sought to investigate the possible correlation between serum/plasma endocan concentration and ARDS.MethodsA systematic review and meta‐analysis of international online databases was conducted following PRISMA guidelines. PubMed, SCOPUS, Embase, and Web of Science were searched in March 2023, with the leading search terms being “ARDS” OR “respiratory distress” AND “endocan” and other associated terms. Studies that measured endocan levels in patients with ARDS and compared it with non‐ARDS controls or within different severities of ARDS were included. We performed a random‐effect meta‐analysis for pooling the differences using standardized mean difference (SMD) and 95% confidence interval (CI).ResultsWe included 14 studies involving 1,058 patients. Those developing ARDS had significantly higher levels of endocan compared to those without ARDS (SMD: 0.47, 95% CI: 0.10–0.84, p = 0.01). Our meta‐analysis of three studies found that endocan levels in ARDS nonsurvivors were significantly higher than in survivors (SMD: 0.31, 95% CI: 0.02–0.60, p = 0.03). Three studies investigated endocan levels in different severities of ARDS. Only one of these studies reported significantly higher endocan levels in patients with worsening acute respiratory failure at Day 15. The other two reported no significant association between ARDS severity and circulating endocan levels.ConclusionBlood endocan levels were significantly higher in patients with ARDS than those without. Additionally, among patients with ARDS, blood endocan values were significantly elevated in nonsurvivors compared to survivors. These findings could help researchers design future studies and solidify these findings and finally, clinicians to take advantage of measuring endocan in clinical settings for assessment of patients with ARDS.

Published: September 2024

AbstractWater, food and energy are crucial for human survival and sustainable development, being interconnected through the water–energy–food (WEF) nexus. Despite extensive research, the significant roles women play in these sectors are often underappreciated. Women are vital in water management, enhancing resource management, water quality and access, particularly in rural areas. In agriculture, they make up a large proportion of the workforce, boosting productivity, promoting sustainable farming practices and ensuring food security. Their deep knowledge of traditional food systems, coupled with their caregiving roles, contributes to providing nutritious and culturally appropriate diets. In the energy sector, women are key advocates for sustainable solutions and grassroots adoption of renewable energy technologies. Recognizing gender equality and empowering women are essential for maximizing their potential in the WEF nexus. Implementing gender‐responsive policies, inclusive decision‐making processes, and investing in education and skills training can significantly enhance women's roles in sustainable management. Empowered women drive innovation and transformative change, leading to more resilient and inclusive governance structures. This article emphasizes the importance of recognizing and supporting women's contributions within the WEF nexus, as this leads to more sustainable and equitable outcomes for all.
