Every patient has health record, it was written as statement of patient's conditions, treatments, and medications, and nowadays it is become digitalized, it can be copied and shared easily, but the nature of EHR is private, not for public, private between patients and healthcare provider. Privacy preserving can be done by implementing Blockchain network for storing EHR, only authorized users or nodes can access and write data to the network. New block in blockchain created as per consensus among nodes, every node can join a blockchain network if it is public, to meet a consensus required resources intensive cryptographic challenge, in private blockchain, only selected can join and involved in the network or specific transaction. In healthcare, data privacy is the main concerned, need a secure, scalable, and efficient blockchain hence implementing consortium blockchain is perfect match for EHR where multiple healthcare provider can operate in a single platform to conduct transaction or sharing EHR among members. This study analyzes 15 articles derived from IEEE Explore, Science Direct and Scopus by implementing screening with keyword Consortium Blockchain and EHR and proposing new blockchain model accommodating solution for challenges on access, storage, sharing, privacy, and performance. © 2022 IEEE.

Urban traffic congestion presents critical challenges, resulting in delays, environmental pollution, and significant economic costs. While traditional traffic control methods, such as fixed-time and adaptive systems, have been widely implemented, they often fail in unpredictable conditions, particularly when confronted with noisy or inaccurate data. This research proposes a robust reinforcement learning (RL) solution for traffic signal control using the RADIAL-DQN (Robust Adversarial Loss DQN) algorithm. Integrating adversarial training enhances the system's robustness to real-world uncertainties. Evaluations conducted using a SUMO traffic simulation show that the robust agent produced an increase of only 60.71% in queue length under a projected gradient descent (PGD) adversarial attack, outperforming standard RL agents, which experienced an 89% increase. These results demonstrate the potential of robust RL to improve both the reliability and scalability of urban traffic control systems. © 2024 IEEE.

Purpose: The purpose of this study was to investigate whether a treadmill endurance exercise program would reduce serum testosterone and leptin in male rats and assess the impact of increased dietary cholesterol on serum hormones. Methods: Male Sprague-Dawley Rats (n = 20) were randomly assigned to a control group (C) or an exercise training group (EX) that performed treadmill running 40 min/day, 6 days/week for 12 weeks. At study midpoint (week 6), rats were randomized to a high-cholesterol (HC) diet (n = 10) or remain on standard semi-purified (LC) diet (n = 10). Results: Results are presented as median [IQR]. At end of week 6, EX + LC had significantly lower body weight (508 [460–527] vs 570 [516–606] g;p = 0.01), mean daily energy intake (76.3 [74.9–82.2] vs 90.9 [86.9–94.5] kcal;p < 0.01), and serum leptin (0.4 [0.3–0.6] vs 3.3 [2.0–4.0] ng/mL;p < 0.01) in comparison to C + LC. No difference was observed between EX + LC and C + LC in serum testosterone (12.6 [6.9–18.3] vs 11.7 [7.6–18.9] ng/mL). At end of week 12, EX + LC had significantly lower body weight (514 [483–568] g) compared to C + LC (644 [575–680] g;p < 0.01) and C + HC (650 [583–702] g;p < 0.01). Serum Leptin in both EX + LC (0.6 [0.2–0.8] ng/mL) and EX + HC (0.6 [0.3–1.6] ng/mL) was significantly lower than C + LC (3.0 [2.2–4.2] ng/mL;p < 0.01). No significant difference in testosterone was observed between C + LC and C + HC (4.3 [3.3–8.3] vs 6.3 [3.2–9.3] ng/mL, respectively). Conclusions: Despite lower energy availability, exercise-induced changes in sex hormones may not occur in training programs ≤ 12 weeks. Lower voluntary energy intake observed in exercise groups despite greater energy expenditure may indicate that lower energy availability in endurance-trained individuals may be inadvertent. © 2018, Springer-Verlag Italia S.r.l., part of Springer Nature.

Fresh water is needed in industrial activities. For these needs sea water is usually used as raw material if the plant is near the sea and far from the river. SWD (sea water desalination) is used to process sea water to fresh water, that is by reducing levels of salinity or reducing levels of total dissolved solid (TDS). There are two technologies in SWD, namely thermal distillation and reverse osmosis (RO) membrane technology. Residual SWD process or also called blowdown water has high salinity levels can be converted into electrical energy through SGP (salinity gradient power). There are two technologies to capture energy from salinity differences, namely PRO (Pressure Retarded Osmosis) and RED (Reverse Electrodialysis). PRO and RED are renewable energy technology, there are no emision, no moving part, abundant availability in nature and can be recycled. In this article, an analysis for SWD of oil refinery is carried out. From the analysis results it is known that the plant uses thermal distillation technology, requires power as 64.25 MW and 3,403 m3/h seawater to produce 242 m3/h freshwater. With SGP, the potential recovery of power gained is 0.786 MW. This recovery potential is still too small when compared to energy requirements of SWD with thermal distillation technology, but if it use RO technology that only requires 3.6-5.7 kWh/m3 or 0.87 - 1.40 MW to produce 242 m3/h, a significant impack to saving energy will be obtained. © Published under licence by IOP Publishing Ltd.

The fabrication of biocomposites studies based on whey protein isolate (WPI) and silica (SiO2) have been conducted. WPI is a biopolymer with high intermolecular bonds and SiO2 can improve the properties of biocomposites. This study aims to analyze the effect of adding SiO2 on the physical and chemical properties of biocomposites. In this work, WPI biocomposite materials containing 0%, 1%, 3%, 5%, and 7% (w/w) SiO2 were prepared by a casting scheme. The results found the increase of SiO2 material, the thickness of the biocomposite material sample increases from 0.178 to 0.205 mm. The water content and solubility in water are enriched under the stimulation of the addition of SiO2 substances, because SiO2 improves adhesiveness of the polymer matrix of the biocomposite. Fourier transform infrared spectroscopy (FTIR) spectra revealed that the intermolecular correlation in biocomposite appeared through O-H, C=O, and N-H. X-ray diffractometer (XRD) studies exhibited that the main structure amorph of biocomposite. The thermal characteristic of the biocomposite were raised by adding SiO2 from 137.48 °C to 153.40 °C. The findings revealed, the incoporation of SiO2 effectuated the water content, solubility in water and thermal properties biocomposite based WPI. © 2022

Over two thousand mud volcanoes have been documented worldwide, predominantly forming in geologically active regions characterized by rapid sedimentation, recent magmatic activity, and compressional tectonics. These features originate from gravitative instability and fluid overpressure, which induce hydrofracturing of impermeable strata, allowing the release of water, gas, and sediments to the surface. As a result, mud volcanoes occur across a range of tectonic and sedimentary settings, including active margins, accretionary complexes, thrust belts, and deep sedimentary basins. They are generally classified as either submarine or terrestrial mud volcanoes, with the former typically associated with tectonic deformation and the later with sediment accumulation in continental settings. Beyond their geological significance, mud volcanoes contribute substantially to global geochemical and biogeochemical processes, influencing methane production and consumption, nutrient cycling, and organic matter transformation. Additionally, microbial communities are essential in the formation and maintenance of mud volcano structures by contributing to the biomineralization of carbonates and sulfates. The microbial communities found in different mud volcanoes are diverse, and their composition can vary based on location, depth, and geochemical conditions. Moreover, these microbial communities have evolved to utilize diverse sources of energy, including hydrogen, methane, and sulfur, to facilitate metabolic processes. This review summarizes the current insights into the formation, distribution, and environmental constraints of mud volcanoes, while highlighting the ecological relevance and metabolic capabilities of associated microbial communities based on metagenomics data to support interdisciplinary research into geobiological interactions in extreme ecosystems. © 2025

This paper proposes a method to estimate the posture of an athlete moving on a vast field in a sporting event using a pan-tilt-zoom camera. In order to estimate the posture of an athlete on a sports field from a dynamic video sequence, our method extracts image features to search correspondence points among successive frames and computes the homography transformation matrix that compensates for changes the camera parameters (e.g., angle of view and posture). The effectiveness of this method is qualitatively verified using MLB TV broadcast video. The accuracy and error factors are also quantitatively verified by CG simulation.

Human blood vessel organoids (hBVOs) have emerged as a system to model human vascular development and disease. Here, we use single-cell multi-omics together with genetic and signaling pathway perturbations to reconstruct hBVO development. Mesodermal progenitors bifurcate into endothelial and mural fates in vitro, and xenografted BVOs acquire definitive arteriovenous endothelial cell specification. We infer a gene regulatory network and use single-cell genetic perturbations to identify transcription factors (TFs) and receptors involved in cell fate specification, including a role for MECOM in endothelial and mural specification. We assess the potential of BVOs to generate organotypic states, identify TFs lacking expression in hBVOs, and find that induced LEF1 overexpression increases brain vasculature specificity. Finally, we map vascular disease-associated genes to hBVO cell states and analyze an hBVO model of diabetes. Altogether, we provide a comprehensive cell state atlas of hBVO development and illuminate the power and limitation of hBVOs for translational research. © 2025 The Authors
