Specific anatomical structures from the female body, such as axillary slope, armpit, pectoral muscle, or abdominal tissue, can be present in mammograms and might affect proper mammogram analysis, especially populations with overweight issues, is case Mexico. This work aims to determine if better results obtained an automatic analysis by removing fatty tissues a preprocessing step. The experimen...

BACKGROUND Changes in single skinfold thickness and body fat have been investigated in ultraswimmers and ultracyclists, but not in ultrarunners. The present study investigated the changes in single skinfold thickness during a 100 km ultramarathon. METHODS Firstly, we investigated associations between prerace preparation and prerace body composition and, secondly, changes in single skinfold th...

The adaptive value of size changes in different organ and muscle groups was studied in red knots (Calidris canutus islandica) in relation to their migration. Birds were sampled on five occasions: at arrival in Iceland in May 1994, two times during subsequent refueling, at departure toward, and on return from, the high arctic breeding grounds. During their 24-d stopover in May, body mass increas...

The new propulsor, whose inspiration is from pectoral fins of fishes, has arisen increasing attention. To improve the performance of the existing labriform bionic pectoral fin, based on the structure and control mechanism of real fish pectoral fin, the under-actuated technology was utilized to design a new flexible bionic pectoral fin. Then, the kinematic model of pectoral fin during fish forwa...
