Privacy preservation is addressed for decentralized optimization, where $N$ agents cooperatively minimize the sum of convex functions private to these individual agents. In most existing optimization approaches, participating exchange and disclose states explicitly, which may not be desirable when contain sensitive information The problem more acute adversaries exist try steal from other To address this issue, we propose a privacy-preserving approach based on alternating direction method...
A triboelectric nanogenerator (TENG) is a potential solution for providing high output power by continuously harvesting ambient energy, which expected to sustainably charge battery the new era-the era of Internet things and sensor networks. Generally, existence parasitic capacitance has been considered be harmful in its performance. Here, we systematically investigate effects structure dimension TENG on performance from point view fabricating two types layered TENGs with considering...

Abstract The high‐output triboelectric nanogenerator (TENG) is indispensable for its practical applications toward industrial products. However, the electricity loss in simple parallel connection among all units and typically high crest factor output seriously hamper of TENG. Here, a rectified TENG reported structure to solve problem connection. rotational contact–separation with phase difference between TENGs addresses extends service life simultaneously. current dramatically decreased 1.31...
Abstract Electrostatic breakdown is a common but generally negative physical phenomenon. Here, efficient conversion of mechanical energy to electric power achieved by enhanced direct‐current triboelectric nanogenerator (DC‐TENG) based on contact electrification and electrostatic breakdown. By verifying the high temperature can not only improve charge density also enhance air dielectric due thermionic emission electrons avalanche effect. Meanwhile an appropriate low atmosphere pressure...
In this work, we propose minimum Bayes risk (MBR) training of RNN-Transducer (RNN-T) for end-to-end speech recognition.Specifically, initialized with a RNN-T trained model, MBR is conducted via minimizing the expected edit distance between reference label sequence and on-thefly generated N-best hypothesis.We also introduce heuristic to incorporate an external neural network language model (NNLM) in beam search decoding explore NNLM.Experimental results demonstrate outperforms substantially...
Circular RNA (circRNA) molecules are noncoding RNAs with unique circular covalently closed structures that contribute to gene expression regulation, protein translation and act as microRNA sponges. circRNAs also have important roles in human disease, particularly tumorigenesis antitumor processes. Methylation is an epigenetic modification regulates the of DNA coding their interactions, well molecules. Previous studies focused on effects methylation circRNA expression, transport, stability,...
Abstract Background Previous studies have demonstrated the role of N6-methyladenosine (m 6 A) RNA methylation in various biological processes, our research is first to elucidate its specific impact on LCAT mRNA stability and adipogenesis poultry. Results The 100-day-old female chickens were categorized into high ( n = 3) low-fat based their abdominal fat ratios, tissues processed for MeRIP-seq RNA-seq. An integrated analysis RNA-seq omics data revealed 16 differentially expressed genes...
