The integration of large-scale wind power and photovoltaics into the system will aggravate voltage fluctuation grid nodes, while when reactive new energy units participates in optimization system, it promote consumption effectively improving stable operation level system. In this work, grey wolf algorithm (GWO) entropy weight is introduced to solve optimal compromise solution multi-objective transmission network, network loss deviation static stability margin are taken as three objective...

Understanding the spatial pattern of human fishing activity is very important for fisheries resource monitoring and management. The environmental preferences tropical tuna purse seine fleet in Western Central Pacific Ocean (WCPO) were constructed compared at different scales based on effort (FE) data from available automatic identification system (AIS) commercial fishery compiled Fisheries Commission (WCPFC), using maximum entropy (MaxEnt) methods. MaxEnt models fitted with FE remote sensing...

Liver cancer is one of the most aggressive tumors and common malignant which seriously threatens human health. Traditional Chinese medicine (TCM) was reported to resist proliferation metastasis liver cells. In this study, we aimed explore potential anti-cancer effect Polygonatum sibiricum polysaccharide (PSP) on tumor immune microenvironment in HepG2 Hep3B cells were pretreated absence or presence PSP (20, 50, 100 µg/mL) for a period 24 h. Subsequently, dendritic (DCs) co-cultured with cell...

This article provides a new perspective of peer effects that coexist in different consumer activities and investigates how consumption household is affected by the level incomes its peers. Using unique panel data on Chinese households between 2011 2019, we explore causal relationship peers' income then analyze plausible mechanisms behind it. We find effect significantly positive. Higher average reference group associated with household's greater expenditure improvement structure. There also...

In recent years, the world has been actively promoting development of wind power, photovoltaic, and other new energy. The inherent randomness intermittency power output have led to reduction supply-side controllability stability, system is facing severe challenges. Aiming at irregular fluctuation restriction between charge discharge depth service life hybrid energy storage equipment, a hierarchical control strategy for based on improved GA-SVR prediction proposed. First all, short-term...

<i>Purpose:</i> This study is designed to investigate the roles of Tiam1 and Rac1 in nasopharyngeal carcinoma (NPC). <i>Methods:</i> NPC samples (n = 102) were analyzed with immunohistochemistry for proteins, 28 which also quantitative RT-PCR Western blots mRNA protein expression. The expression noncancerous tissue 26) acted as a control. was gauged regarding stage, grade survival. <i>Results:</i> overexpressed cells their upregulation significantly...

Herein, we have successfully established a novel, rapid, and simple lateral-flow immunoassay based on time-resolved fluorescence biotin-streptavidin to detect the residues of various antibiotics in milk. The signal sensitivity immunochromatography were enhanced through biotinylated antibody coupled with streptavidin europium microspheres. Moreover, due use QR Code fluorescent reader, quantitative detection real-time data uploading can be achieved. Under optimal conditions, antibiotic...

Ecological fishery management requires high-precision information to support resource and marine spatial planning. In this paper, the Automatic Identification System (AIS) was adopted extract on fishing grounds of light purse seine vessels in Northwest Pacific Ocean. The distributions mapped by data mining, kernel density analysis hotspot methods were compared. similarity index applied determine consistency between computed fisheries information. Finally, derived best method used investigate...

Under the background of large-scale and rapid development renewable energy, in order to improve economic benefit system ensure reliability system, this paper introduces hydrogen production energy storage into independent wind/photovoltaic/hydrogen/storage capacity optimization configuration method. In minimize total planning cost self-sufficiency rate power supply, a allocation model was established. On basis model, Multi-objective Salp Swarm Algorithm (MOSSA) improved structure, Tent...

Ecosystem-based fisheries management requires high-precision information to provide relevant data for natural resource management, assessment, and marine spatial planning. This study utilizes Automatic Identification System (AIS) from light purse seine vessels the Chinese mainland that were collected May November between 2020 2022, along with corresponding environmental data. By applying boosted regression trees (BRTs) generalized additive models (GAMs), this establishes nonlinear...

Understanding the dynamic spatial distribution and characteristics of fishing activities is crucial for fisheries management sustainable development. In recent years, small pelagic fish cephalopods in Arabian Sea have become new targets light purse seine fishing; however, there a lack publicly available reports.
