La kératose séborrhéique (KS), anciennement appelée verrue séborrhéique ou verrue séborrhéique papillaire hyperkératosique , est une tumeur cutanée bénigne, qui survient essentiellement chez le sujet âgé au-delà de 50 ans. Elle est fréquente sur le tronc, le visage et rare dans la région génitale .Elles forment des lésions en relief, bien limitées, comme posées sur la peau, d'aspect squamokérat...

pour Sorokin. Or ces formes linéaires cöıncident. Si on croit à la philosophie des périodes [4], l’égalité de ces intégrales doit pouvoir se démontrer par une suite de changements de variables et d’applications des règles d’additivité (par rapport à l’intégrande ou au domaine) et du théorème de Stokes. En l’occurrence, un seul changement de variables suffit (voir le théorème 2.1). Les intégrale...

Most number systems use a single base – e.g., 10 or 2 – and represent each number as a combination of powers of the base. However, historically, there were two civilizations that used a more complex systems to represent numbers. They also used bases: Babylonians used 60 and Mayans used 20, but for each power, instead of a single digit, they used two. For example, a number 19 was represented by ...

The Sri Lankan Twin Registry began as a volunteer register in 1997. Previously, we have shown door-to-door surveys as the best option to build a population-based twin register of older, adult twins. Our aim was to build a population-based twin register in the Colombo district and use it for twin studies on common mental disorders. We aimed to identify a random sample of 4000 twins ascertained t...

BACKGROUND The occurrence of multiple births has been recognized as a risk factor for child maltreatment. However, few population-based studies have examined the relationship between multiple births and child maltreatment. This study aimed to evaluate the degree of risk of child maltreatment among singletons and multiple births in Japan and to identify factors associated with increased risk. ...

Many datasets have multiple perspectives – for example space, time and description – and often analysts are required to study these multiple perspectives concurrently. This concurrent analysis becomes difficult when data are grouped and split into small multiples for comparison. A design challenge is thus to provide representations that enable multiple perspectives, split into small multiples, ...

Imaging of multiples, as a supplement to imaging primaries, can provide wider range subsurface illumination. Therefore, it more detailed information on structures. However, multiples suffers from crosstalk issues generated by unrelated events. Many strategies have been proposed attenuate crosstalk, among which the angle domain Radon attenuation algorithm achieves good application effect. In dom...
