Aging is thought to be caused by the accumulation of damage, primarily from oxidative modifications of cellular components by reactive oxygen species (ROS). Here we used yeast methionine sulfoxide reductases MsrA and MsrB to address this hypothesis. In the presence of oxygen, these antioxidants could increase yeast lifespan and did so independent of the lifespan extension offered by caloric res...

Ample evidence shows that KDD has become a major topic of interest in both research and industry in China since 2006. In academia, professor Zhi-Hua Zhou at Nanjing University in 2006 chaired a National Machine Learning workshop, inviting researchers in the greater China area to share their experience. In 2009, the first Asian Conference on Machine learning was inaugurated in Nanjing. In indust...

The performance of grant-free random access (GF-RA) is limited by the number accessible resources (RRs) due to absence collision resolution. Compressive sensing (CS)-based RA schemes scale up RRs at expense increased non-orthogonality among transmitted signals. This paper presents design multi-sequence spreading (MSRA) which employs multiple sequences spread different symbols a user as opposed ...

In TREC-10, Microsoft Research Asia (MSRA) participated in the Web track (ad hoc retrieval task and homepage finding task). The latest version of the Okapi system (Windows 2000 version) was used. We focused on the developing of content-based retrieval and linkbased retrieval, and investigated the suitable combination of the two. For content-based retrieval, we examined the problems of weighting...

Screening a Helicobacter pylori genomic library with antisera raised against H. pylori broth culture supernatant resulted in the identification of six antigens: urease, HspB, Lpp20, DnaK, MsrA, and a cysteine-rich 28-kDa protein (designated HcpA). H. pylori antigens may be released into the extracellular space by multiple mechanisms, including specific secretion pathways, autolysis, and membran...

This paper mainly describes a Chinese named entity recognition (NER) system NER@ISCAS, which integrates text, partof-speech and a small-vocabularycharacter-lists feature and heristic postprocess rules for MSRA NER open track under the framework of Conditional Random Fields (CRFs) model.

Methionine sulfoxide reductase (Msr) catalyzes the thioredoxin-dependent reduction and repair of methionine sulfoxide (MetO). Although Msr genes are not present in most hyperthermophile genomes, an Msr homolog encoding an MsrA-MsrB fusion protein (MsrAB(Tk)) was present on the genome of the hyperthermophilic archaeon Thermococcus kodakaraensis. Recombinant proteins corresponding to MsrAB(Tk) an...

Scene text detection has become a popular topic in computer vision research. Most of the current research is based on deep learning, using Convolutional Neural Networks (CNNs) to extract visual features images. However, due limitations convolution kernel size, CNNs can only local images with small perceptual fields, and they cannot obtain more global features. In this paper, improve accuracy sc...
