Oculocutaneous albinism (OCA) is an inherited disorder affecting the visual system and skin pigmentation. Our aim was to evaluate genetic clinical heterogeneity in a cohort of Slovenian paediatric patients with clinically suspected OCA using advanced molecular-genetics approach. In as much 20 out 25 patients, variants explaining their phenotype were identified. The great majority (15/25) had TY...

Three of the four HPS samples previously confirmed by the ALI in São Paulo tested positive by our ELISA. Of the remaining 12 suspected HPS cases assayed, three were positive. Two of these three were later confirmed as positive by the ALI (Luiza Teresinha Madia de Souza, ALI, pers. comm.) Thus, we report three previously unconfirmed HPS cases, one fatal, in the Ribeirão Preto area between May 19...

Vectorial vortex light beams, also referred to as spirally polarized beams, are of particular interest since they can be exploited in several applications ranging from quantum communication to spectroscopy and microscopy. In particular, symmetric pairs of vector beams define two-dimensional spaces which are described as "hybrid Poincaré spheres" (HPS). While generation of vortex beams has been ...

For SAT and CIRCUIT -SAT there is an obvious brute force algorithm that requires 2m time where n is the number of variables and m is a measure of the overall input size. How much better we can seems to depend on the input structure. In the case of kSAT there are some improvements. Theorem 1.1 (Paturi-Pudlak,Schöning,Paturi-Pudlak-Saks-Zane,Hertli). For constants 1 ≤ c ≤ 2, there are (randomized...
