Protein binding site prediction is an important prerequisite task of drug discovery and design. While sites are very small, irregular varied in shape, making the challenging. Standard 3D U-Net has been adopted to predict but got stuck with unsatisfactory results, incomplete, out-of-bounds, or even failed. The reason that this scheme less capable extracting chemical interactions entire region hardly takes into account difficulty segmenting complex shapes. In paper, we propose a refined...

It is critical to accurately predict the rupture risk of an intracranial aneurysm (IA) for timely and appropriate treatment because fatality rate after 50%. Existing methods relying on morphological features (e.g., height-width ratio) measured manually by neuroradiologists are labor intensive have limited use assessment. Therefore, we propose end-to-end deep-learning method, called TransIAR net, automatically learn from 3D computed tomography angiography (CTA) data status IA rupture. We...

Protein binding site prediction is an important prerequisite for the discovery of new drugs. Usually, natural 3D U-Net adopted as standard framework to do per-voxel binary mask classification. However, this scheme only performs feature extraction single-scale samples, which may bring loss global or local information, resulting in incomplete, artifacted even missed predictions. To tackle issue, we propose a network called GLPocket, based on Lmser (Least mean square error reconstruction) and...

Abstract Flood forecast models have become better through research as they led to a lower risk of flooding, policy ideas, less human death, and destruction property, so this study uses Scientometric analysis for floods. In analysis, citation-based data are used uncover major publishing areas, such the most prominent keywords, top best commonly publications, highly cited journal articles, countries, authors that achieved consequent distinction in flood analysis. Machine learning (ML)...

It is an essential step to locate the binding sites or pockets of drug molecules on protein structure in design. This challenging because 3D structures are usually complicated, irregular shape and relatively small. Existing deep learning methods for this task U-Net models, they have forward skip connections efficiently transfer features different levels from encoder decoder improving pocket prediction. However, there still room improve prediction accuracy. In paper, we propose RecurPocket, a...

Methods are developed for eliciting a Dirichlet prior based upon stating bounds on the individual probabilities that hold with high probability. This approach to selecting is applied contingency table problem where it demonstrated how assess respect bias induces as well check prior-data conflict. It shown assessment of hypothesis via relative belief can easily take into account what means falsity correspond difference practical importance and provide evidence in favor hypothesis.

Existing single image super-resolution (SISR) methods usually focus on Low-Resolution (LR) images which are artificially generated from High-Resolution (HR) by a down-sampling process, but not robust for unmatched training set and testing set. This paper proposes GAN Flexible Lmser (GFLmser) network that bidirectionally learns the High-to-Low (H2L) process degrades HR to LR Low-to-High (L2H) recovers back images. The two directions share same architecture, added with gated skip connections...

The Seriphidium transiliense desert pasture is an important spring-autumn in northern Xinjiang, China, and has been subjected to grazing by livestock at different intensities, thus resulting widespread deterioration of its biodiversity ecosystem services. To understand the response mechanism stoichiometric characteristics vegetation grazing, leaf carbon (C), nitrogen (N), phosphorus (P) C : N P ratios S. were studied under intensities. results show that control C, contents N, 458.79 ± 53.5...

Current face recognition tasks are usually carried out on high-quality images, but in reality, most images captured under unconstrained or poor conditions, e.g., by video surveillance. Existing methods featured learning data uncertainty to avoid overfitting the noise, adding margins angle cosine space of normalized softmax loss penalize target logit, which enforces intra-class compactness and inter-class discrepancy. In this paper, we propose a deep Rival Penalized Competitive Learning...
