An N-bromosuccinimide-catalyzed intermolecular annulation of acetyl indoles with alkynes was developed, allowing for regioselective formation valuable carbazoles through direct C-H bond functionalization. The readily available catalyst, wide substrate scope, gram scale synthesis, and mild conditions make this method practical. Mechanistic investigations indicate that the bromination indole takes place to generate a bromide intermediate, followed by coupling an alkyne intramolecular...

Facial expression recognition (FER) plays a significant role in our daily life. However, annotation ambiguity the datasets could greatly hinder performance. In this paper, we address FER task via label distribution learning paradigm, and develop dual-branch Adaptive Distribution Fusion (AdaDF) framework. One auxiliary branch is constructed to obtain distributions of samples. The class emotions are then computed through each emotion exclude existing distributions. Finally, those two...

In the Markov decision process model, policies are usually evaluated by expected cumulative rewards. As this criterion is not always suitable, we propose in paper an algorithm for computing a policy optimal quantile criterion. Both finite and infinite horizons considered. Finally experimentally evaluate our approach on random MDPs data center control problem.

In recent years, artificial intelligence has been widely used in the field of network security, which significantly improved effect security analysis and detection. However, because power industrial control system is faced with problem shortage attack data, direct deployment intrusion detection based on problems lack low precision, high false alarm rate. To solve this problem, we propose an anomaly traffic method cross-domain knowledge transferring. By using TrAdaBoost algorithm, achieve a...

Many reported proteasome inhibitors, including the three clinically approved bortezomib, carfilzomib, and ixazomib, have peptidic structures. In this study, using a hybrid versatile strategy for covalent virtual screening by combining warhead preprocessing with GOLD CovDock software that were applied to ZINC library, we identified multiple inhibitors new nonpeptidic structural scaffolds. Proteasome inhibition assays confirmed inhibitory activities of these compounds. These results...

To separate objects (immature tomatoes, foreign material) accurately from tomatoes using actuating mechanism of tomato color grading robot, high-speed photography was used to acquire images the sorting process for studying effect between cast position and track separating. Test results show that affects sorting; conveyer belt hitting pneumatic ejection finger directly. High-speed is analysis at high speed, which can be helpful design robot.

Conflict detection algorithm in the traditional firewall rules, increase when number of rules to a certain extent, probability conflict will increase, which match packets cause miscarriage justice. In order be able quickly detect conflict, this paper presents an improved rule algorithms (DBBV algorithm). The processes on using binary tree data structure, and one-dimensional intersection operation after operation, makes simpler detect. Expression flexibility not due redundant resulting high...
