With the continuous accumulation of users' check-in data, we can gradually capture behavior patterns and mine preferences. Based on this, next point-of-interest (POI) recommendation has attracted considerable attention. Its main purpose is to simulate habits behavior. Then, different types context information are used construct a personalized model. However, data extremely sparse, which leads low performance in model training using recurrent neural network. Therefore, propose category-aware...
The objective of this study was to investigate the individual and combined contamination aflatoxin B1 (AFB1), zearalenone (ZEN) deoxynivalenol (DON) in feedstuffs from different Provinces China between 2016 2017. A total 1569 samples, including 742 feed ingredients 827 complete pig were collected various regions for mycotoxins analysis. results showed that occurrence rates AFB1, ZEN, DON more than 83.3%, 88%, 74.5%, respectively, all tested samples. most prevalent contaminant, followed by...
Climate change represents a grave challenge to the global economy, environment, and societal well-being, jeopardizing their long-term sustainability. In response this urgent issue, study emphasizes significance of environmental policy energy transitions as fundamental factors in addressing climate crisis. The research draws upon data from OECD countries spanning period between 1990 2020, utilizing robust econometric techniques assess properties. utilizes comprehensive CS-ARDL model,...
The first catalytic asymmetric construction of axially chiral 4-aryl α-carboline skeletons has been accomplished through an N-heterocyclic carbene (NHC)-catalyzed atroposelective formal [3 + 3] annulation 4-nitrophenyl 3-arylpropiolates with 2-sulfonamidoindolines. synthetic utility the title compounds demonstrated by diverse late-stage structural modifications. Density functional theory calculations were also conducted to illuminate key factors for controlling origin enantioselectivity....
Sports matches are very popular all over the world. The prediction of a sports match is helpful to grasp team's state in time and adjust strategy process match. It's challenging effort predict Therefore, method proposed result next by using teams' historical data. We combined Long Short-Term Memory (LSTM) model with attention mechanism put forward an AS-LSTM for predicting results. Furthermore, ensure timeliness prediction, we add sliding window make have better timeliness. Taking football...
An N-heterocyclic carbene (NHC)-catalyzed formal [4 + 2] annulation of 2-aryl-3 H-indol-3-ones with α,β-unsaturated carboxylic acids bearing γ-H was developed via an in situ activation strategy. The reaction involves the γ-addition vinyl enolates to unique cyclic ketimines afford chiral tricyclic indolin-3-ones a quaternary carbon center at 2-position. This protocol provides rapid and enantioselective pathway access novel class structurally important C2-quaternary that might be useful for...
An N-heterocyclic carbene and photoredox cocatalyzed α-amino-acid decarboxylative carbonylation reaction is presented. This method displays good scope generality, providing a direct pathway to access various downstream α-amino ketones under bio- medicinally compatible conditions. Moreover, this strategy appealing chemical biology because it has great potential for the modification of peptides or late-stage synthesis keto-peptides.
Edge-computing-enabled smart greenhouses are a representative application of the Internet Things (IoT) technology, which can monitor environmental information in real-time and employ to contribute intelligent decision-making. In process, anomaly detection for wireless sensor data plays an important role. However, traditional algorithms originally designed static do not properly consider inherent characteristics stream produced by sensors such as infiniteness, correlations, concept drift, may...
An efficient and concise strategy has been successfully developed for merging spiro-tetrahydroquinoline with spiro-benzofuranone into a single new skeleton through asymmetric catalytic cascade reactions catalyzed by quinine-derived chiral bifunctional squaramide organocatalysts. In this approach, differently substituted derivatives were smoothly obtained high yields, excellent diastereoselectivities enantioselectivities (up to 99% yield, up >20 : 1 dr, >99% ee, 40 examples) under mild...
Non-Abelian optics has emerged as a promising research field with the potential to revolutionize our understanding of light–matter interactions and enable new applications in areas including topological photonic devices, quantum computing, optical sensing, communications. This review provides an overall framework for rapidly developing non-Abelian properties optics, basic concepts physical mechanism statistics, gauge braiding special phenomenon field, current challenges opportunities. is...
Introduction It remains a big challenge to identify patients who are at high risk of developing severe acute kidney injury (AKI) after cardiac surgery. This study investigated the clinical utility urinary cytokeratin 20 (uCK20), novel biomarker reflecting severity histological tubular injury, for identifying AKI. Methods prospective multicenter cohort enrolled Test set comprising 413 underwent surgery in 5 centers and Validation enrolling 131 an external center. uCK20 six reported renal...
The structurally interesting pyrano[3,2-<italic>b</italic>]indol-2-ones were synthesized by an N-heterocyclic carbene-catalyzed formal [3 + 3] annulation of alkynoic acid esters.
Turnip (Brassica rapa L.) is widely consumed as a vegetable and traditional Chinese medicine with high dietary fiber content. Soluble (SDF) insoluble (IDF) were obtained from white turnips, the IDF was modified alkaline hydrogen peroxide to obtain (MIDF) SDF (MSDF). The compositional, structural, functional properties of four samples investigated. After modification, fibers (MDFs) showed smaller particle sizes lower contents pectin polyphenol than those unmodified (DFs) results scanning...
Abstract Wildfire activity is an important in evolution of vegetation and carbon cycling. Whether wet weather will suppress wildfire or promote them by increasing fuel reserves during the Holocene not clear. We obtained a record black from sediment core spanning last 14.8 kyr Gonghai Lake, North China. There close relationship between timing development driven East Asian summer monsoon intensity. On millennial timescales, climatic conditions provide sufficient biofuels reserve, same period...
