The nucleus of Comet 2P/Encke was detected with the Arecibo radar during the close approach of November, 2003, making this the first comet to yield radar detections at two different apparitions. Although the measured radar cross section of 1.0 km2 was close to that obtained in 1980, the Doppler bandwidth was nearly four times larger. Most of this bandwidth difference can simply be attributed to...

La granulomatose vénérienne est une infection qui, depuis son apparition épidémique en 2003, survient principalement chez les hommes ayant des rapports sexuels avec hommes. Cet article présente un aperçu données actuelles.

Described for the first time by John Kelso Ormond in 1948, idiopathic retroperitoneal fibrosis usually involves Gerota’s fascia and compresses the ureters leading to the apparition of progressive lumbar pain and urinary dysfunction inducing various degrees of renal failure. In certain cases, other organ might be affected inducing a different clinical aspect, in the absence of urinary tract invo...

The magnetization process of Co/Al oxide/Py trilayers and its evolution with the temperature have been analyzed. The particular behavior of the Co layers, including the shift of the hysteresis loops and a coercivity increase with the decrease of temperature, is related with the apparition of a CoO layer at the Co/Al-oxide interface.

We review some results concerning the apparition of finite time singularities in nonlinear Schrödinger equations with a Gaussian additive noise which is white in time and correlated in space. We then extend the results to the case where the noise is real valued, which is the case in some physical situations.
