As an alternative to the watermarking approach, content-based copy detection (CBCD) recently has become a promising technique for video monitoring and copyright protection. In this paper, a novel CBCD framework is proposed. Firstly, robust global feature (DCT), local features (SIFT) and audio feature (EDF) are first combined to describe video and audio(More)
It is suspected that some neurodegenerative diseases are a result of the disturbance of copper (Cu) homeostasis, although it remains unclear whether the disturbance of Cu homeostasis has aberrant effects on neurons. Herein, we investigated Cu metabolism specifically in neurons in terms of changes in the intracellular Cu concentration and the expression of(More)
In this paper, we present a new variations of the popular nonnegative matrix factorization (NMF) approach to extend it to the data with negative values. When a NMF problem is formulated as X ≈ HW, we try to develop a new method that only allows W to contain nonnegative values, but allows both X and H to have both nonnegative and negative values. In(More)
Targeted and nontargeted biopolymeric nanoparticles with identical hydrodynamic sizes and surface charges were quantitatively examined in terms of the pharmacokinetic and biodistribution differences in detail. In adding cancer cell targeting folate molecules to the surface of the heparin nanocarriers, the amount of drug delivered to the tumor is doubled,(More)
Gossip-based protocols for group communication have attractive scalability and reliability properties. In this paper, we extend our previous work: a gossip-based protocol that enables agents to reach a consensus based on a special uninorm aggregation operator. We theoretically analyze the convergence and the randomness features of the extensions. The(More)
Palmitic acid (PA) is known to cause cardiomyocyte dysfunction. Cardiac hypertrophy is one of the important pathological features of PA-induced lipotoxicity, but the mechanism by which PA induces cardiomyocyte hypertrophy is still unclear. Therefore, our study was to test whether necroptosis, a receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3-)(More)
The aim of this study is to construct specific shRNA expressing plasmids, and to observe their effects on H9c2 cardiomyocytes injury induced by hypoxia/reoxygenation (H/R). RIPK1 and RIPK3 are the key kinases mediating the process of necroptosis. Using recombinant DNA technology, we inserted the synthetic shRNA into pSUPER vector to construct RIPK1-shRNA or(More)
In this paper, we describe BUPT-MCPRL systems for TRECVID 2011. Our team participated in five tasks: semantic indexing, known-item search, instance search content-based copy detection and surveillance event detection. A brief introduction is shown as follows: In this year, we proposed two different methods: one based on text and another is bio-inspired(More)
The present study aimed to investigate miR-590-3p's role in osteogenic differentiation of human mesenchymal stem cells (hMSC). HMSC were cultured and transfected with empty vector, miR-590-3p vector to construct control hMSC and miR-590-3p overexpression hMSC. MiR-590-3p suppressed hMSC was created with oligonucleotide transient transfection. All 3 groups(More)
