CD1 represents a third lineage of antigen-presenting molecules that are distantly related to major histocompatibility complex (MHC) in the immune system. The crystal structure mouse CD1d1, corresponding human CD1d, at 2.8 Å resolution shows adopts an MHC fold is more closely class I than II. binding groove, although significantly narrower, substantially larger because increased depth and it has only two pockets almost completely hydrophobic. extreme hydrophobicity shape site consistent with...

This paper comparatively investigated the removal efficiency and mechanisms of rice straw biochars prepared under three pyrolytic temperatures for two kinds tetracycline quinolone antibiotics (doxycycline ciprofloxacin). The influencing factors antibiotic adsorption (including biochar dosage, pH, background electrolytes, humic acid, initial concentration, contact time, temperature) were comprehensively studied. results suggest that produced at high-temperature [i.e., 700°C (BC700)], have...

This paper studies the multi-modal recommendation problem, where item multi-modality information (e.g., images and textual descriptions) is exploited to improve accuracy. Besides user-item interaction graph, existing state-of-the-art methods usually use auxiliary graphs user-user or item-item relation graph) augment learned representations of users and/or items. These are often propagated aggregated on using graph convolutional networks, which can be prohibitively expensive in computation...

Nowadays, with the rapid growth of microblogging networks for news propagation, there are increasingly more people accessing through such emerging social media. In meantime, fake now spreads at a faster pace and affects larger population than ever before. Compared traditional text news, posted on microblog often has attached images in context. So how to correctly autonomously detect fakes multi-modal manner becomes prominent challenge be addressed. this paper, we propose an end-to-end model,...

Hitherto, Cu2 Se incorporated with a dispersed second phase shows extremely low thermal conductivity and excellent thermoelectric properties. However, the significant mismatch in electronic band structure between phases matrix often causes deterioration of carrier mobility. In this work, based on density functional theory (DFT) calculations, is adjusted through doping S Te. It found that Se0.88 S0.06 Te0.06 has highly similar to matrix, which results high mobility power factor Se-based...

The six‐satellite Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) mission makes routine ionospheric measurements over the entire globe using occultation techniques. These observations have been used in this study to develop global‐scale climate maps of N m F 2 h f during southern (northern) summer (winter). Enhanced electron densities that appear be associated with southern, equatorial (Appleton) anomaly are displaced far southward at dusk and, within about an...

Recommendation systems have become popular and effective tools to help users discover their interesting items by modeling the user preference item property based on implicit interactions (e.g., purchasing clicking). Humans perceive world processing modality signals audio, text image), which inspired researchers build a recommender system that can understand interpret data from different modalities. Those models could capture hidden relations between modalities possibly recover complementary...

Abstract BACKGROUND Antibiotics are widely used for the treatment of bacterial infections in humans and animals, but it can be released into water sources due to incomplete metabolism or via discharge from drug manufacturers. RESULTS The efficiency removal three antibiotics was enhanced with increasing biochar dosage. adsorption by RH700 much higher than RH300 RH500, which might larger surface area pore volume (211.76 m 2 g ‐1 6.25 nm, respectively). In addition, capacity greatly affected...

Suburban areas are the transitional zone between urban and rural areas, serving as key for addressing issues related to regional sustainable development. In this study, 294 prefecture-level cities in China were selected research objects. The spatial heterogeneity of social, economic, natural characteristics, well vitality realization suburbs China, was quantitatively analyzed at a national scale, impact socio-economic factors on suburban discussed. results show that has large with 431 km2...

Urban green space (UGS) is essential to the improvement of human well-being and health, inequity UGS supply has received widespread concern. The urban availability (UGSA) can effectively evaluate supply. However, UGSA under different daily transportation patterns not enough attention, as well potential that available by patterns. Meanwhile, between cities with economic development levels at regional or national scale still unclear. So, we constructed seven indicators represent supply:...

Sequential recommendation systems often suffer from data sparsity, leading to suboptimal performance. While multimodal content, such as images and text, has been utilized mitigate this issue, its integration within sequential frameworks remains challenging. Current models are unable effectively explore capture correlations among behavior sequences of users items across different modalities, either neglecting sequence representations or inadequately capturing associations between in their...

Currently, much of machine learning is opaque, just like a "black box." However, in order for humans to understand, trust and effectively manage the emerging AI systems, an needs be able explain its decisions conclusions. In this paper, I propose argumentation-based approach explainable AI, which has potential generate more comprehensive explanations than existing approaches.

Recent advances in sequential recommendation models have demonstrated the efficacy of integrating pre-trained text embeddings with item ID to achieve superior performance. However, our study takes a unique perspective by exclusively focusing on untapped potential embeddings, obviating need for embeddings. We begin implementing pre-processing strategy known as whitening, which effectively transforms anisotropic semantic space into an isotropic Gaussian distribution. Comprehensive experiments...
