BACKGROUND Obesity is a major health burden worldwide. A method of assessing uncompressed subcutaneous adipose tissue thickness (USATT) using ultrasound is widely used in sports medicine. However, studies on the reliability of the method in non-athletic people are lacking. We aim to determine the reliability of the human observer in measuring the USATT in non-athletic people. MATERIAL AND MET...

11 Objective: Manipulation of the colonoscope is a technical challenge for novice clinicians which is 12 best learned in a simulated environment. It involves the coordination of scope tip steering with 13 scope insertion, using a rotated image as reference. The purpose of this work is to develop and 14 validate a system which objectively assesses colonoscopy technical skills proficiency in an a...

We investigate what would be the consequences for leptogenesis of the existence of a charged SU(2)L singlet scalar δ . If such a scalar particle exists it allows the right-handed neutrinos to couple not only to left-handed lepton and Higgs doublets as in ordinary leptogenesis, but also to a right-handed charged lepton and a δ. This provides a new source of leptogenesis which can be successful i...

Many natural shapes are chiral (or handed). Our hands, for example, have a righthand version and a left-hand version, the two types being mirror images of each other. Molecules are also classi ed according to their chirality, which determines their chemical characteristics. Glucose, for example, is sweet only in one chirality, while it is tasteless in the other. The notion of chirality for two ...
