In this paper, we deal with the estimation of body and head poses (i.e orientations) in surveillance videos, and we make three main contributions. First, we address this issue as a joint model adaptation problem in a semi-supervised framework. Second, we propose to leverage the adaptation on multiple information sources (external labeled datasets, weak(More)
For the last two decades, intelligent transportation systems (ITS) have emerged as an efficient way of improving the performance of transportation systems, enhancing travel security, and providing more choices to travelers. A significant change in ITS in recent years is that much more data are collected from a variety of sources and can be processed into(More)
Plant viral movement proteins (MPs) enable viruses to pass through cell walls by increasing the size exclusion limit (SEL) of plasmodesmata (PD). Here, we report that the ability of Cucumber mosaic virus (CMV) MP to increase the SEL of the PD could be inhibited by treatment with the actin filament (F-actin)-stabilizing agent phalloidin but not by treatment(More)
The Bayesian occupancy filter (BOF) (Coue et al., 2002) has achieved promising results in the object tracking applications. This paper presents a new development of BOF which inherits original BOF's advantages. Meanwhile, the new formulation has significantly reduced original BOF's complexities and can be run in realtime. In Bayesian occupancy filter, the(More)
The viral proteases have proven to be the most selective and useful for removing the fusion tags in fusion protein expression systems. As a key enzyme in the viral life-cycle, the main protease (M(pro)) is most attractive for drug design targeting the SARS coronavirus (SARS-CoV), the etiological agent responsible for the outbreak of severe acute respiratory(More)
In surveillance videos, cues such as head or body pose provide important information for analyzing people’s behavior and interactions. In this paper we propose an approach that jointly estimates body location and body pose in monocular surveillance video. Our approach is based on tracks derived by multi-object tracking. First, body pose classification is(More)
We initiate a systematic study to help distinguish a special group of online users, called hidden paid posters, or termed "Internet water army" in China, from the legitimate ones. On the Internet, the paid posters represent a new type of online job opportunities. They get paid for posting comments or articles on different online communities and websites for(More)
The immunohistochemical analysis was used to evaluate the expression of PD-L1 in 109 non-small cell lung cancer (NSCLC) tissues and para-tumor tissues. Associations between expressed PD-L1 and tumor histological types, degree of differentiation, and lymph node metastasis were calculated, and overall survival was assessed. Meanwhile, immunohistochemistry and(More)
Advanced glycation end products (AGEs) boost the generation of reactive oxygen species (ROS) in glomerular mesangial cells (GMCs), and thereby play important roles in diabetic nephropathy (DN). Sirtuin 1 (Sirt1), a protein deacetylase, is known to markedly protect cells from oxidative stress (OSS) injury. Based on the critical involvements of AGEs and Sirt1(More)
