INTRODUCTION Determine body composition changes in adiposity can assess an individual. OBJECTIVE The objective of this study was to evaluate total body fat percentage based on two and four compartment models in obese Chilean school children, adjusting for differences in sex and puberty status. METHODS Sixty-one obese school children (33 boys and 28 girls) between 8 and 13 years of age were ...

<p style='text-indent:20px;'>We identify two new traveling waves of the Holling-Tanner model with weak diffusion. One connects constant states; at one them, is undefined. The other a state to periodic wave train. We exploit multi-scale structure in diffusion limit. Our analysis uses geometric singular perturbation theory, compactification and blow-up method.</p>

Geometric methods in the theory of Chevalley groups and their generalisations have made tremendous advances during the last few decades. Among the most noteworthy and influential of these advances are the systematic application of the concept of amalgams based on [49], [59], [117], the local-to-global approach [134], ingenious applications of combinatorial topology and geometric group theory (a...

Perinatal testicular torsion (PTT) is a rare entity. The management of PTT is controversial, due to the low viability of the testis and the possibility of bilateral torsion. This is a review of our experience with six cases of PTT, highlighting diagnostic and therapeutic difficulties of this condition.

Different components of the autonomic nervous system may be affected by different disorders to varying degrees. The aim of this study is to report first experiences with a new device (FAN(R), Schwarzer, Germany) which measures heart rate variability (HRV), sympathetic skin responses (SSR) and the pulse wave transit time (PTT). We examined 190 healthy volunteers (102 men, 88 women) and in 89 sub...

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive tumors with low survival rates and the leading cause of death in neurofibromatosis type 1 (NF1) patients under 40 years old. Surgical resection is the standard of care for MPNSTs, but is often incomplete and can generate loss of function, necessitating the development of novel treatment methods for this patient population. Here, w...

Discrete choice experiments (DCEs) are robust stated-preference methods frequently used to estimate maximum acceptable risk (MAR) as a secondary outcome. However, DCEs provide sample-level estimates and explaining preference heterogeneity for MARs based on participant characteristics can be difficult. The study objective was compare the capability of DCE probabilistic threshold technique (PTT) ...

Let S(v) be a function deened on the vertices v of the innnite binary tree. One algorithm to seek large positive values of S is the Metropolis-type Markov chain (X n) deened by P (X n+1 = wjX n = v) = 1 3 e b(S(w)?S(v)) 1 + e b(S(w)?S(v)) for each neighbor w of v, where b is a parameter (\1=temperature") which the user can choose. We introduce and motivate study of this algorithm under a probab...

The Password-authenticated key exchange (PAKE) protocols allow parties to share secret keys in an authentic manner based on an easily memorizable password. On the other hand, the protocol should resist all types of password guessing attacks, since the password is of low entropy. Recently Lu Cao proposed a simple three-party password based authenticated key exchange (S-3 PAKE) protocol and claim...

BACKGROUND Studies have yet to determine the optimal height at which the posterior tibial tendon (PTT) can be re-routed and the tendon length discrepancy at different height levels in terms of PTT transfer via the circumtibial route. This cadaveric study was conducted to determine the optimal height of PTT subcutaneous transfer and to compare tendon length discrepancies at different heights. ...
