This paper presents a novel compact coding approach, composite quantization, for approximate nearest neighbor search. The idea is to use the composition of several elements selected from the dictionaries to accurately approximate a vector and to represent the vector by a short code composed of the indices of the selected elements. To efficiently compute the(More)
In this paper we present a novel real-time algorithm for simultaneous pose and shape estimation for articulated objects, such as human beings and animals. The key of our pose estimation component is to embed the articulated deformation model with exponential-maps-based parametrization into a Gaussian Mixture Model. Benefiting from this probabilistic(More)
p300, a transcriptional co-activator with histone acetyl transferase (HAT) activity, plays an essential role in the pathogenesis of cardiomyocyte hypertrophy in response to multiple pro-hypertrophic stimuli including hyperglycemia. However, the precise mechanisms by which p300 expression is regulated remain unclear. The purpose of this study was to(More)
This study was designed to explore the correlation between expressions of SATB1 and S100A4 and their relationships to the clinicopathologic parameters of colorectal carcinoma (CRC). Expressions of SATB1 and S100A4 were evaluated by immunohistochemistry in a cohort of 131 primary CRC patients undergone surgical resection from 2005 to 2007. SATB1 and S100A4(More)
Actinomycetes are a major source of antimicrobials, anticancer compounds, and other medically important products, and their genomes harbor extensive biosynthetic potential. Major challenges in the screening of these microorganisms are to activate the expression of cryptic biosynthetic gene clusters and the development of technologies for efficient(More)
Memristors have been extensively studied for data storage and low-power computation applications. In this study, we show that memristors offer more than simple resistance change. Specifically, the dynamic evolutions of internal state variables allow an oxide-based memristor to exhibit Ca(2+)-like dynamics that natively encode timing information and regulate(More)
Crossbar arrays of memristive elements are investigated for the implementation of dictionary learning and sparse coding of natural images. A winner-take-all training algorithm, in conjunction with Oja's rule, is used to learn an overcomplete dictionary of feature primitives that resemble Gabor filters. The dictionary is then used in the locally competitive(More)
Inflammatory macrophages in colonic mucosa are the leading drivers of the pathology associated with inflammatory bowel disease (IBD). Here we examined whether gadolinium chloride (GdCl3), a macrophage selective inhibitor, would improve the course of 2,4,6-trinitro benzene sulfonic acid (TNBS) and dextran sodium sulfate (DSS)-induced colitis in mice and the(More)
The demand for high speed, low power and low cost for Viterbi decoding especially in wireless communication are always required. Thus this paper presents the design of an adaptive Viterbi decoder that uses survivor path with parameters for wireless communication in an attempt to reduce the power and cost and at the same time increase the speed. Viterbi(More)
