In this paper, we present an improved fuzzy C-means (FCM) algorithm for image segmentation by introducing a tradeoff weighted fuzzy factor and a kernel metric. The tradeoff weighted fuzzy factor depends on the space distance of all neighboring pixels and their gray-level difference simultaneously. By using this factor, the new algorithm can accurately(More)
Successful sexual reproduction in animals and plants requires communication between male and female gametes. In flowering plants, unlike in animals, eggs and sperm cells are enclosed in multicellular embryo sacs and pollen grains, respectively; guided growth of the pollen tube into the ovule is necessary for fertilization. Pollen tube guidance requires(More)
Previous study in our laboratory demonstrates that microinjection of galanin into the arcuate nucleus of hypothalamus produced antinociceptive effects in rats. In the present study we investigated the involvement of protein kinase C (PKC) and PKC signaling pathways in the galanin-induced antinociception in the brain of rats. Intracerebroventricular(More)
We report a new method for the synthesis of hollow-structured phenylene-bridged periodic mesoporous organosilica (PMO) spheres with a uniform particle size of 100-200 nm using α-Fe(2)O(3) as a hard template. Based on this method, the hollow-structured phenylene PMO could be easily functionalized with MacMillan catalyst (H-PhPMO-Mac) by a co-condensation(More)
To investigate the effect of taurine on alcoholic liver disease in rats, male Wistar rats were administered alcohol intragastrically for 3 months. The effect of β-alanine-mediated taurine depletion and taurine administration on the development of alcoholic liver disease was examined. It was found that taurine administration produced lower levels of(More)
A heuristic approach is presented to solve continuum topology optimization problems with specified constraints, e.g., structural volume constraint and/or displacement con-straint(s). The essentials of the present approach are summarized as follows. First, the structure is regarded as a piece of bone and the topology optimization process is viewed as bone(More)
Based on self-adaptive fuzzy PID control, the autopilot for the longitudinal channel of UAV is designed, which uses the theory of self-adaptive control and combines the traditional PID control method with Fuzzy control method. Simulation results show that the algorithm of the self-adaptive fuzzy PID controller is easy. And the self-adaptive capacity of the(More)
Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders and it causes long-lasting visceral pain and discomfort. AMPA receptor mediated long-term potentiation (LTP) has been shown to play a critical role in animal models of neuropathic and inflammatory pain. No report is available for central changes in the ACC of mice(More)
OBJECTIVE To report laparoscopic splenectomy in goats. STUDY DESIGN Experimental study. ANIMALS Healthy female goats (n=9); aged, 10-18 months; weighing, 22-30 kg. METHODS Food was withheld for 24 hours and water for 10 hours. Anesthetized right laterally recumbent goats had a laparoscopic portal and 3 instrumental portals created in the left flank.(More)
How to maintain the population diversity is an important issue in designing a multiobjective evolutionary algorithm. This paper presents an enhanced nondominated neighbor-based immune algorithm in which a multipopulation coevolutionary strategy is introduced for improving the population diversity. In the proposed algorithm, subpopulations evolve(More)
