Hot-Pressed Super-Elastic Graphene Aerogel with Bidirectional Thermal Conduction Properties as Thermal Interface Materials

Traditional graphene-based films normally possess high thermal conductivity (TC) only along a single direction, which is not suitable for thermal interface materials (TIMs). Here, a graphene film with excellent bidirectional TC and mechanical properties was prepared by hot-pressing super-elastic graphene aerogel (SEGA). Thermal annealing at 1800 °C improves the further restacking of graphene sheets, bringing high structure stability to SEGA for enduring the hot-pressing process. The junctions and nodes between the graphene layers in the hot-pressed SEGA (HPSEGA) film provide bidirectional heat transport paths. The in-plane TC and through-plane TC of HPSEGA film with a thickness of 101 μm reach 740 Wm−1K−1 and 42.5 Wm−1K−1, respectively. In addition, HPSEGA film with higher thickness still maintains excellent thermal transport properties due to the interconnected structure reducing the effect of the defects. The infrared thermal images visually manifest the excellent thermal-transfer capability and thermal-dissipation efficiency of the HPSEGA films, indicating the great potential as advanced bidirectional TIMs.

Combination Therapy with Enalapril and Paricalcitol Ameliorates Streptozotocin Diabetes-Induced Testicular Dysfunction in Rats via Mitigation of Inflammation, Apoptosis, and Oxidative Stress

Background: As the impacts of diabetes-induced reproductive damage are now evident in young people, we are now in urgent need to devise new ways to protect and enhance the reproductive health of diabetic people. The present study aimed to evaluate the protective effects of enalapril (an ACE inhibitor) and paricalcitol (a vitamin D analog), individually or in combination, on streptozotocin (STZ)-diabetes-induced testicular dysfunction in rats and to identify the possible mechanisms for this protection. Material and methods: This study was carried out on 50 male Sprague-Dawley rats; 10 normal rats were allocated as a non-diabetic control group. A total of 40 rats developed diabetes after receiving a single dose of STZ; then, the diabetic rats were divided into four groups of equivalent numbers assigned as diabetic control, enalapril-treated, paricalcitol-treated, and combined enalapril-and-paricalcitol-treated groups. The effects of mono and combined therapy with paricalcitol and enalapril on testicular functions, sperm activity, glycemic state oxidative stress, and inflammatory parameters, as well as histopathological examinations, were assessed in comparison with the normal and diabetic control rats. Results: As a result of diabetes induction, epididymal sperm count, sperm motility, serum levels of testosterone, follicle-stimulating hormone (FSH) as well as luteinizing hormone (LH), and the antioxidant enzyme activities, were significantly decreased, while abnormal sperm (%), insulin resistance, nitric oxide (NO), malondialdehyde (MDA), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were significantly increased, along with severe distortion of the testicular structure. Interestingly, treatment with paricalcitol and enalapril, either alone or in combination, significantly improved the sperm parameters, increased antioxidant enzyme activities in addition to serum levels of testosterone, FSH, and LH, reduced insulin resistance, IL-6, and TNF-α levels, and finally ameliorated the diabetes-induced testicular oxidative stress and histopathological damage, with somewhat superior effect for paricalcitol monotherapy and combined therapy with both drugs compared to monotherapy with enalapril alone. Conclusions: Monotherapy with paricalcitol and its combination therapy with enalapril has a somewhat superior effect in improving diabetes-induced testicular dysfunction (most probably as a result of their hypoglycemic, antioxidant, anti-inflammatory, and anti-apoptotic properties) compared with monotherapy with enalapril alone in male rats, recommending a synergistic impact of both drugs.
Air quality model simulating photochemical formation of pollutants: the Sao Paulo Metropolitan Area, Brazil

The main sources of ozone precursors in the atmosphere of the Sao Paulo Metropolitan Area (SPMA) in Brazil are emissions from gasoline-, ethanol-, and diesel-powered vehicles. Ozone is a significant air quality problem in the SPMA. To come into compliance with the National Ambient Air quality Standard for Ozone, emission reduction policies must be established. An adequate emissions inventory and a description of the meteorology and chemistry involved are needed in order to evaluate the effectiveness of methodologies that reduce the effect of vehicle emissions on ozone formation. During the period 10–12 August 1999, concentrations of ozone in the SPMA and the impact of the official emissions inventory were simulated through application of an urban-scale Eulerian model. We found that using the official inventory in simulations resulted in ozone values much lower than those observed and nitrogen oxide emission profiles that were overestimated by a factor of approximately two.
A Rare Case of Non-Neurological Ptosis

Ptosis in pediatrics is commonly attributed to neurological causes. Rarely, chronic inflammation of the upper eyelid and the formation of giant papillary conjunctivitis due to vernal keratoconjunctivitis (VKC) may lead to ptosis. In this case report, we present an eight-year-old girl with conjunctivitis who was referred to a pediatric neurology service for evaluation of ptosis. She presented with progressive left-eye ptosis while experiencing allergic conjunctivitis. Her neurological exam showed non-fatigable ptosis with a negative curtain sign. The rest of the neurology examination was normal. She tested negative for anti-MuSK and anti-Ach. The orbital MRI was unremarkable. Further detailed examination by an ophthalmologist showed severe VKC with a giant papillary formation that had led to mechanical ptosis.
RESEARCH ON THE VOLCANIC EARTHQUAKE ACTIVITY MECHANISM IN CHANGBAISHAN TIANCHI AREA

The researches of volcanic earthquake activities recorded at Tianchi Volcano Observatory(TVO) since 1999 showed that the volcanic earthquake activities changed their features before or after the occurrence of the intermediate-deep earthquakes,magnitude 5.0 or larger than that,in the Northwestern Pacific Ocean.Our statistical data revealed the following three cases: the first one is that,the volcanic earthquakes became strengthening followed the deep earthquakes;the second is that,the intermediate-deep earthquakes took place after the volcanic earthquake swarm;and the third one is the volcanic earthquakes took place before or after the intermediate-deep earthquakes.That means that the intermediate or deep earthquakes happened while the volcanic earthquakes at Tianchi volcano became relatively less.In this paper,we present a Mt.Changbai mantle plume model and discuss a preliminary mechanism of the volcanic earthquake activities,by studying the recent volcanic earthquakes activities of Mt.Changbai and the intermediate-deep earthquakes of the Northwestern Pacific subducting plate,the feature of the basaltic mantle and the Mt.Chanbai geothermal activities,based on the former researcher's achievements.
The State of the Art for Cross-Modal Retrieval: A Survey

Cross-modal retrieval, which aims to search for semantically relevant data across different modalities, has received increasing attention in recent years. Deep learning, with its ability to extract high-level representations from multimodal data, has become a popular approach for cross-modal retrieval. In this paper, we present a comprehensive survey of deep learning techniques for cross-modal retrieval including 37 papers published in recent years. The review is organized into four main sections, covering traditional subspace learning methods, deep learning, and machine learning-based approaches, techniques based on large multi-modal models, and an analysis of datasets used in the field of cross-modal retrieval. We compare and analyze the performance of different deep learning methods on benchmark datasets, the result shows that although a large number of innovative methods have been proposed, there are still some problems that need to be solved, such as multi-modal feature alignment, multi-modal feature fusion, and subspace learning, as well as specialized datasets.

Global increase in plant carbon isotope fractionation following the Last Glacial Maximum caused by increase in atmospheric pCO2

Changes in the carbon isotope composition of terrestrial plant tissue (δ13C) are widely cited for evidence of shifts in climate, vegetation, or atmospheric chemistry across a wide range of time scales. A global compilation of δ13C data from fossil leaves and bulk terrestrial organic matter (TOM) spanning the past 30 k.y. , however, shows wide variability and no discernable trend. Here we analyze these data in terms of a relative change in net carbon isotope fractionation between the δ13C value of plant tissue and that of atmospheric CO2 [Δ13C = (δ13CCO2 – δ13C)/(1 + δ13C/1000)] and identify a global 2.1‰ shift in leaf and TOM Δ13C that is synchronous with a global rise in p CO2 documented from ice core data. We apply a relationship describing the effect of p CO2 on Δ13C to the global record of Δ13C change documented here to reconstruct p CO2 levels across the past 30 k.y. Our reconstructed p CO2 levels are in excellent agreement with the ice core data and underscore the potential of the global terrestrial δ13C record to serve as an accurate p CO2 proxy.
Therapeutic Potential for Beta-3 Adrenoreceptor Agonists in Peripheral Arterial Disease and Diabetic Foot Ulcers

Annually, peripheral arterial disease is estimated to cost over USD 21 billion and diabetic foot disease an estimated at USD 9–13 billion. Mirabegron is a TGA-approved beta-3 adrenoreceptor agonist, shown to be safe and effective in the treatment of overactive bladder syndrome by stimulating bladder smooth muscle relaxation. In this review, we discuss the potential use of beta-3 adrenoreceptor agonists as therapeutic agents repurposed for peripheral arterial disease and diabetic foot ulcers. The development of both conditions is underpinned by the upregulation of oxidative stress pathways and consequential inflammation and hypoxia. In oxidative stress, there is an imbalance of reactive oxygen species and nitric oxide. Endothelial nitric oxide synthase becomes uncoupled in disease states, producing superoxide and worsening oxidative stress. Agonist stimulation of the beta-3 adrenoreceptor recouples and activates endothelial nitric oxide synthase, increasing the production of nitric oxide. This reduces circulating reactive oxygen species, thus decreasing redox modification and dysregulation of cellular proteins, causing downstream smooth muscle relaxation, improved endothelial function and increased angiogenesis. These mechanisms lead to endothelial repair in peripheral arterial disease and an enhanced perfusion in hypoxic tissue, which will likely improve the healing of chronic ulcers.
Genetic Collections of St. Petersburg University

Bioresource collections represent a unique source of biological diversity for research in genetics and related disciplines. The Department of Genetics and Biotechnology of St. Petersburg State University is the oldest department of genetics in Russia, founded in 1919. Throughout the entire period of development, the geneticists of St. Petersburg University have collected unique forms of plants, animals and microorganisms, on which their research was based. Many of these studies including regulation of translation termination in yeast, amyloids and prions of different organisms, genetic mapping of valuable morphological and biochemical traits to create first rye chromosome maps, and several aspects of transcription regulation in plants, had a significant novelty. The most active accumulation of collections of genetic resources at St. Petersburg State University started in the 1950-1970s when important scientific directions in the genetics of microorganisms, plants and animals, many of which continue today, were established at the department. Genetic collections are actively used in educational work for teaching dozens of educational courses. Currently, the interdisciplinary genetic collections of St. Petersburg State University consist of seven sections including genetic collections of rye, radish, garden pea, Chlamydomonas algae, Saccharomyces yeast and plasmids, Komagataella yeast, Drosophila fly. This review describes in detail the collections of the Department of Genetics and Biotechnology of St. Petersburg State University and discusses their current state, application and development prospects.
The obesity paradox in intracerebral hemorrhage: a systematic review and meta-analysis

Background Intracerebral hemorrhage (ICH) has a mortality rate which can reach 30–40%. Compared with other diseases, obesity is often associated with lower mortality; this is referred to as the ‘obesity paradox’. Herein, we aimed to summarize the studies of the relations between obesity and mortality after ICH. Method For this systematic review and meta-analysis (PROSPERO registry CRD42023426835), we conducted searches for relevant articles in both PubMed and Embase. Non-English language literature, irrelevant literature, and non-human trials were excluded. All included publications were then qualitatively described and summarized. Articles for which quantitative analyses were possible were evaluated using Cochrane’s Review Manager. Results Ten studies were included. Qualitative analysis revealed that each of the 10 studies showed varying degrees of a protective effect of obesity, which was statistically significant in 8 of them. Six studies were included in the quantitative meta-analysis, which showed that obesity was significantly associated with lower short-term (0.69 [0.67, 0.73], p<0.00001) and long-term (0.62 [0.53, 0.73], p<0.00001) mortality. (Data identified as (OR [95%CI], p)). Conclusion Obesity is likely associated with lower post-ICH mortality, reflecting the obesity paradox in this disease. These findings support the need for large-scale trials using standardized obesity classification methods. Systematic review registration https://www.crd. york.ac. uk/prospero/display_record. php?

Telugu letters dataset and parallel deep convolutional neural network with a SGD optimizer model for TCR

Because of the rapid growth in technology breakthroughs, including multimedia and cell phones, Telugu character recognition (TCR) has recently become a popular study area. It is still necessary to construct automated and intelligent online TCR models, even if many studies have focused on offline TCR models. The Telugu character dataset construction and validation using an Inception and ResNet-based model are presented. The collection of 645 letters in the dataset includes 18 Achus, 38 Hallus, 35 Othulu, 34×16 Guninthamulu, and 10 Ankelu. The proposed technique aims to efficiently recognize and identify distinctive Telugu characters online. This model's main pre-processing steps to achieve its goals include normalization, smoothing, and interpolation. Improved recognition performance can be attained by using stochastic gradient descent (SGD) to optimize the model's hyperparameters.

Traffic Monitoring using SRTM Along-Track

In February 2000, the Shuttle Radar Topography Mission SRTM was flown as the first single-pass SAR interfer- ometer in space. The goal was to obtain a global digital elevation model. Therefore, a secondary receive-only antenna on the tip of a 60 m long deployable mast supplemented the primary transmit and receive antenna mounted in the shuttle cargo bay. Due to mechanical constraints, the interferometric baseline did not only consist of the terrain height sensitive across track component but also contained an along track component of 7 m. The resulting time lag between the data acquisitions by the two antennas causes phase differences, which are proportional to the line-of- sight velocity of moving targets. Since this system ability has been expected prior to the SRTM launch, a traffic mo nitoring experiment has been carried out during the mission, which showed a surprisingly good agreement between the GPS velocity measurements on ground and the measurement from space. A strategy to exploit the along track interferometric (ATI) phase and the coherence together with the azimuth displacement of moving vehicles in focused SAR images has been developed and applied on sample test sides for traffic monitoring on highways. I. INTRODUCTION For traffic flow monitoring and control the need for remote sensing data, acquired day and night under all weather condi- tions, becomes a demanding issue. Adequately designed SAR systems could be an answer (6). This was the motivation for the experiment being presented.
Evaluating managerial competence of small, medium and micro-entrepreneurs to ensure sustainable economic development in eThekwini municipal area

This research investigates the influence of Small, Medium, and Micro Entrepreneurs (SMMEs) on sustainable economic development in the eThekwini Municipal Area of South Africa. It focuses on the capability of SMME managers and operators to efficiently and effectively utilise available resources, ensuring their enterprises make a meaningful contribution to sustainable economic growth. Data was gathered from a diverse set of SMMEs in the eThekwini Municipal Area using a simple random sampling method, with 229 entrepreneurs participating. Key findings reveal that entrepreneurs underscore the importance of knowledge, skills, value judgments, behavioural traits, and social networks in establishing and operating successful businesses. A notable challenge identified was their limited ability to identify viable business opportunities. Nevertheless, these entrepreneurs demonstrate a commitment to maintaining their local environments and providing employment opportunities to community members, and some contribute to community development initiatives. The primary recommendation emerging from this study is providing support and tools to assist potential entrepreneurs in effectively recognising and seizing business opportunities.
Evapotranspiration amplifies European summer drought

Drought is typically associated with a lack of precipitation, whereas the contribution of evapotranspiration and runoff to drought evolution is not well understood. Here we use unique long‐term observations made in four headwater catchments in central and western Europe to reconstruct storage anomalies and study the drivers of storage anomaly evolution during drought. We provide observational evidence for the “drought‐paradox” in that region: a consistent and significant increase in evapotranspiration during drought episodes, which acts to amplify the storage anomalies. In contrast, decreases in runoff act to limit storage anomalies. Our findings stress the need for the correct representation of evapotranspiration and runoff processes in drought indices.
CONTRIBUIÇÕES NO ALGORITMO DE RASTREAMENTO DO PONTO DE MÁXIMA POTÊNCIA EM LOCAIS COM GRANDE VARIAÇÃO DE IRRADIÂNCIA

Resumo. Um método para o rastreamento do ponto de máxima potência em módulos fotovoltaicos utilizando duas técnicas distintas em paralelo é proposto. Esse método utiliza o algoritmo Perturba e Observa (P&O), que é uma técnica simples e eficiente de rastreamento, trabalhando em paralelo com uma técnica via modo deslizantes, que é uma técnica robusta e de fácil implementação. Para validação da proposta, foi simulado um conversor Boost utilizando o método, e comparado com o mesmo conversor com um método P&O modificado. Os dados de radiação foram obtidos com auxílio de uma estação solarimétrica capaz de aquisitar os dados a cada segundo, que evidencia a grande variação da irradiação durante o dia na cidade de Natal. Os resultados numéricos demostraram que, em comparação com o P&O, o método proposto obtém uma velocidade de rastreamento mais rápida e uma melhor eficiência
DIAGNOSIS AND SIMULATION OF INFLUENCE OF VAPOR TRANSPORTATION TO SUMMER RAIN'S TYPE CHANGES IN EASTERN CHINA

A method of Singular Value Decomposition(SVD)is used to study the relationship between vapor transportation and summer rain in eastern China.The result shows that increase of vapor flux in the Southern China Sea will raise rain in South China and the Jianghuai River;and also increase of vapor flux in Bengal bay will increase rain in South China and decrease rain in the Jianghuai River.By changing vapor flux in Southern China Sea and Bengal bay in a series of sensitive experiments with a regional climate model of RegCM3,we found that vapor flux changes in two key zone will not change the basic rain type but will affect rain in some areas,and this testify the diagnostic result in some ways.
