Analysis of pre-crash characteristics of passenger car to cyclist accidents for the development of advanced drivers assistance systems.

The purpose of this study was to analyze car-to-cyclist accidents to determine the challenges for an active safety system on car to avoid accidents. Based on 2261 car-to-cyclist accidents provided by in-depth accident databases, accidents are analyzed more specifically from kinematic reconstructions. The main accident scenarios are determined: crossing nearside, crossing farside, longitudinal, turning (right and left) and others.

A ring system detected around the Centaur (10199) Chariklo.

Hitherto, rings have been found exclusively around the four giant planets in the Solar System. Rings are natural laboratories in which to study dynamical processes analogous to those that take place during the formation of planetary systems and galaxies. Their presence also tells us about the origin and evolution of the body they encircle.

Isochromosome 12p mosaicism (Pallister mosaic aneuploidy or Pallister-Killian syndrome): report of 11 cases.

We report on 11 cases of isochromosome 12p mosaicism (or Pallister mosaic aneuploidy syndrome) in which the isochromosome is usually absent in cultured lymphocytes but present in fibroblasts. The patients range in age from a 22-week-gestation fetus to a 45-year-old man. They have a distinct pattern of anomalies which enables one to make a diagnosis based on clinical manifestations alone.

Chromosome 13 long arm interstitial deletion associated with features of Noonan phenotype.

A 22-year-old Caucasian mildly retarded male presented with facial features of high nasal bridge, prominent supraorbital ridges, some malar hypoplasia, prognathism, short philtrum, and prominent full lips associated with shortness of stature, nuchal webbing, and esotropia. His cardiac exam and genital development were normal. The diagnosis of Noonan syndrome had been previously entertained.

Children with Marfan's syndrome and pectus excavatum.

Pectus excavatum occurs in two thirds of children with Marfan's syndrome. The characteristics of seven children with Marfan's syndrome and pectus excavatum were compared with those of 38 children who had pectus excavatum without Marfan's syndrome. The children with Marfan's syndrome presented later, had progressive defects, and were more likely to have wound problems; however, acceptable cosmetic and functional results after chest wall repair were obtained in the patients with Marfan's syndrome.
