Experiment results show the effectiveness and excellence on different noisy images of the proposed algorithm.

In order to accurately extract the epicardium of the left ventricle from cardiac magnetic resonance images, a method based on developed dynamic programming is proposed. First, the endocardium is segmented by the Otsu method. Then, the epicardium is derived by designing an improved dynamic programming method to find a closed path with minimum local cost. The key to this method is the design of the local cost function, which consists of three factors: boundary gradation, boundary gradient and shape features. The weighting coefficients of the three factors are obtained by a chaos particle swarm optimization method. A comparison with other segmentation methods and the gold standard is provided based on 138 images. The experimental results show that the method proposed has high accuracy and robustness.

From November to December, 2010, the selected body temperature (T_sel), critical thermal maximum (T_CTMax), the diel variation in body temperature,post-prandial selected body temperature of Japalura splendida were measured under laboratory conditions. The T_sel and T_CTMax of J. splendida were (26.22±0.65) ℃ and (42.35±0.41) ℃, respectively. In a gradient of 15~30 ℃, the body temperature (T_b) was positively correlated with ambient temperature (T_e): T_b=0.663T_e+7.193. In the environment without thermal gradients, diel variation in body temperature was not significantly affected by environment temperatures (T₁₁=0.643,P=0.534). There were no significant differences in T_sel between fasted and fed lizards(F_{2, 104}=0.997, P=0.372). The results indicated that:(1)The body temperature of J.splendida changed with environment temperature. (2)J. splendida could conduct its body temperature by physiological thermoregulation. (3) The diffences of T_CTMax among J. splendida and other lizards may be related to their geographical distribution. (4)T_sel of J. splendida did not vary significantly between fasted and fed, while may be related to its food.

Stable δ¹³C and δ¹⁵ N is a very effective technology used to research material circulation and energy flow in ecosystem. The δ¹³C value is commonly used for the analysis of consumer food source. The δ¹⁵ N value is commonly used to determine the living creature position in the food web. Stable δ¹³C and δ¹⁵ N are used to to research the trophic level relationship of Guizhou Shibingxia cave and Mulaotang cave. The result showed that fauna enrichment on the δ¹³C and δ¹⁵N enrichment were obvious in Shibingxia cave and Mulaotang cave. Two caves enrichment spans on the δ¹³C (the difference between the maximum and minimum values) were 4.911 4‰ and 6.292 8 ‰ respectively and on the δ¹⁵N were 6.687 0‰ and 5.056 0‰. But on the whole, the two ecosystems enrichment on δ¹⁵N is much stable than on δ¹³C. So it is concluded that the two caves enrichment factors on the δ¹⁵N value are 2.808 0 and 2.420 0 respectively by using the level δ¹⁵ N value to evaluate the level of nutrition. The trophic levels have three levels. They are as follows. The first trophic level is soil organic matter. The second trophic level is Kronopolites sp., Gastroptychia sp. and Distrammena sp. which feed on soil organic matter. The third trophic level is Oreolalax rhodostigmatus, spiders and bats taxa.
