A number of papers claim that a Log Periodic Power Law (LPPL) fitted to financial market bubbles that precede large market falls or ‘crashes’, contain parameters that are confined within certain ranges. The mechanism that has been claimed as underlying the LPPL, is based on influence percolation and a martingale condition. This paper examines these claims and the robustness of the LPPL for capt...

OBJECTIVESS Aerial sports can cause serious injuries. The rate of injuries is nevertheless reasonably low, contrary to popular belief. This study aimed to evaluate the rate and severity of injuries to ASI patients presented to our Emergency Department (ED). MATERIAL AND METHODS The study was held at a university medical center. The patients who were presented or transferred to the ED in a fou...

The main purpose of this study was to examine the effect of chalk on the friction coefficient between climber's fingers and two different rock types (sandstone and limestone). The secondary purpose was to investigate the effects of humidity and temperature on the friction coefficient and on the influence of chalk. Eleven experienced climbers took part in this study and 42 test sessions were per...

— We discuss recent developments in the study of the homotopy classes for the Sobolev spaces W 1, p (M ; N). In particular, we report on the work of H. Brezis Y. Li [5] and F.B. Hang F.H. Lin [9].

Recently it has been shown that in patients with transposition of the great arteries the isometric relaxation time of the left ventricle could be negative in the presence of normal pulmonary artery pressure. In order to find an explanation for this apparently paradoxical situation, it was decided to evaluate the importance of the delay of closure of the pulmonary valve in 15 patients with trans...

Cyclic feeding schedules are now commonly used in conjunction with closed enteral feeding systems. Some manufacturers and clinicians have speculated that closed system cyclic feeding may promote formula contamination via retrograde movement of bacteria during the "no-flow" periods. Using both laboratory and clinical settings, our study evaluated whether retrograde bacterial movement under "no-f...
