Embedding-based recommender systems rely on historical interactions to model users, which poses challenges for recommending new known as the user cold-start problem. Some approaches incorporate social networks deduce preferences based circles of users solve problem sparse features. However, such methods have difficulty distinguishing between superficial correlations and causal relationships in behaviors, leading inaccuracies predicting preferences. To address aforementioned issues, we...
Abstract Selenium exposure can induce liver insulin resistance and increased triglyceride concentrations in animals, which may link to an risk of nonalcoholic fatty disease (NAFLD). However, epidemiological studies investigating the association between elevated plasma selenium levels NAFLD were not available. We aimed investigate with prevalence Chinese adults. This was a cross-sectional study 8550 adults aged 40 yr or older Shanghai, China. A questionnaire, anthropometric measurements,...
Underwater acoustic signal denoising technology aims to overcome the challenge of recovering valuable ship target signals from noisy audios by suppressing underwater background noise. Traditional statistical-based techniques are difficult be applied effectively in complex environments, especially case extremely low signal-to-noise ratios (SNRs). To address these problems, we propose a noise-aware deep learning model with fullband-subband attention network (NAFSA-Net) for denoising. NAFSA-Net...
Despite the reported successes and advantages involving use of amphiphilic surfactants, most notably TPGS-750-M, to enable a multitude synthetic transformations be conducted in water, implementation this methodology within pharmaceutical industry has been relatively limited. In paper, we will disclose key results learnings from multicompany collaboration focused on reproducibility study some commonly used reaction types industry, specifically amidation, SNAr, nitro reduction, reductive...
Abstract Advances in data assimilation (DA) methods and the increasing amount of observations have continuously improved accuracy initial fields numerical weather prediction during last decades. Meanwhile, order to effectively utilize rapidly data, Earth scientists must further improve DA methods. Recent studies introduced machine learning (ML) assist process. In this paper, we explore potential a four‐dimensional variational (4DVar) constrained neural network (NN) method for accurate DA....
<title>Abstract</title> Objective Dyslipidemia has been found to promote platelet activation and aggregation, contributing the formation of atherosclerotic plaques. This study aims explore relationship between lipid profiles indices (PI) among middle-aged older people without cardiovascular disease (CVD) history. Methods A total 9,406 individuals from Chongming, Shanghai, meeting criteria were included. Serum lipids measured on an automatic analyzer platelets using blood cell analyzer. Based...

Abstract Many agricultural regions in China are likely to become appreciably wetter or drier as the global climate warming increases. However, impact of these change patterns on intensity soil greenhouse gas (GHG) emissions (GHGI, GHG per unit crop yield) has not yet been rigorously assessed. By integrating an improved ecosystem model and a meta‐analysis multiple field studies, we found that is expected cause 20.0% yield loss, while stimulating by 12.2% between 2061 2090 China's regions. A...
Sea surface temperature (SST) prediction has attracted increasing attention, due to its crucial role in understanding the Earth’s climate and ocean system. Existing SST methods are typically based on either physics-based numerical or data-driven methods. Physics-based rely marine physics equations have stable explicable outputs, while flexible adapting data capable of detecting unexpected patterns. We believe that these two types method complementary each other, their combination can...
A review and comparison of the tectonic history North China Slave cratons reveal that two have many similarities some significant differences. The rest in conclusion both a Wilson Cycle, having experienced rifting an old continent late Archean, development rift to passive margin sequence, collision this with arcs within 100–200 Ma formation margin, reversal subduction polarity, then eventual climactic another arc terrane, microcontinental fragment, or continent. This cycle demonstrates...
Peanut (Arachis hypogaea L.) is one of the most important crops produced worldwide. dominant crop in typical upland red soil areas China; however, phosphorus bioavailability very low, which severely affects peanut production. To improve bioavailability, substantially promotes green development production, a peanut–green manure rotation field experiment was conducted with six treatments (milkvetch; radish; brassica rape; mustard winter fallow and no-tillage), commencing September 2017 area...
Abstract Agricultural soils play a dual role in regulating the Earth's climate by releasing or sequestering carbon dioxide (CO 2 ) soil organic (SOC) and emitting non‐CO greenhouse gases (GHGs) such as nitrous oxide (N O) methane (CH 4 ). To understand how agricultural can solutions requires comprehensive assessment of net GHG balance (i.e., sum SOC‐sequestered CO emissions) underlying controls. Herein, we used model‐data integration approach to quantify natural anthropogenic factors have...
Enhancing the path planning capabilities of ships is crucial for ensuring navigation safety, saving time, and reducing energy consumption in complex maritime environments. Traditional methods, reliant on static algorithms singular models, are frequently limited by physical constraints ships, such as turning radius, struggle to adapt environment’s variability emergencies. The development reinforcement learning has introduced new methods perspectives addressing environments, achieving...
Though cloud computing has many advantages, it still faces a big challenge of security and privacy problem. This problem is also an obstacle to since no one willing run his businesses in facilities he control over it. Moreover, multi-tenancy IT service mode, there should be capability compartmentalize different customers facilities; therefore, duty separation between CSP must supported cloud. However, this not common traditional mechanisms. Multi-tenancy based access model (MTACM) was...
