Many applications require continuous monitoring of a moving target by a controllable vision system. Although the goal of tracking objects is not new, traditional techniques usually ignore the presence of obstacles and focus on imaging and target recognition issues. For a target moving among obstacles, the goal of tracking involves a complex motion problem:(More)
BACKGROUND Cystathionine-γ-lyase (CSE)-derived hydrogen sulfide (H2S) is a potent cardioprotective agent. We investigated the effects of diallyl trisulfide (DATS) on CSE expression and H2S generation in myocardium and examined whether DATS-mediated H2S generation effectively protects rat heart from diabetes-induced cardiac damage. METHODS The correlations(More)
This paper describes a new approach to keep a moving target into the eld of view of a robot, despite obstacles. Unlike previous work, this approach does not assume that a complete or partial model of the target's behavior is available, nor that a map of the obstacles is given. At approximately 10 Hz, the robot constructs a local map of the environment from(More)
Semantic annotation of images is an important step to support semantic information extraction and retrieval. However, in a multi-annotator environment, various types of conflicts such as converting, merging, and inference conflicts could arise during the annotation. We devised conflict detection patterns based on different data, ontology at different(More)
Ambidextrous organizations exploit existing technologies to enable incremental innovation while exploring new opportunities to foster radical innovation. Whether this dual pursuit is effective in furthering performance goals, however, remains inconclusive in the literature. Departing from the ambidexterity literature, which acknowledges in general the(More)
Although the influence of the technological diversity of R&D alliance partners on a focal firm's performance has been discussed for several years, there are no sufficient consistent evidences to support the notion that technological diversity of partners has specific effect on the focal firm's performance. This study therefore tests hypotheses with(More)
Victim cache can buffer blocks discarded from the cache on a miss before going to the next lower-level memory to improve performance. Compared with the previous work, rather than only improve performance, we design a modified victim cache to reduce power consumption by minimizing accesses to L2 cache, miss rate, and miss penalty in this paper. With the help(More)
The complete mitochondrial genome of the Cyprinid fish Gobiobotia intermedia (Cypriniformes, Cyprinidae) was determined. The complete mitogenome sequence has 16,608 bp and contains the usual 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA (tRNA) genes and a non-coding control region, as those found in other vertebrates, with the gene order(More)
