Nature-inspired algorithms are a very promising tool for solving the hardest problems in computer sciences and mathematics. These algorithms are typically inspired by the fascinating behavior at display in biological systems, such as bee swarms or fish schools. So far, these algorithms have been applied in many practical applications. In this paper, we present a simple particle swarm optimizati...

www.sciencemag.org SCIENCE VOL 336 11 MAY 2012 637 COVER Enhanced-color view of the “Snowman” craters (Marcia, Calpurnia, and Minucia) on the asteroid Vesta generated by combining imaging and topography data from NASA’s Dawn spacecraft. The 60-kilometer-wide Marcia crater (at bottom) is one of the youngest large craters on Vesta with a small central peak, as well as light and dark streaks on it...

Ependymoma usually arises within the ventricles and central canal of the spinal cord. These tumors, found in the sellar region, are extremely rare. We report a case of pituitary ependymoma followed up over 10 years. A 59-year-old male patient presented with fatigue, general weakness, erectile dysfunction, and loss of body hair, including pubic hair. Brain magnetic resonance imaging (MRI) reveal...

The inositol pyrophosphate disphosphoinositol pentakisphosphate (PP-InsP(3)/InsP(7)) is formed in mammals by two recently cloned inositol hexakiphosphate kinases, InsP(6)K1 and InsP(6)K2 (Saiardi, A., Erdjument-Bromage, H., Snowman, A. M., Tempst, P., and Snyder, S. H. (1999) Curr. Biol. 9, 1323-1326). We now report the identification, cloning, and characterization of a third InsP(7) forming en...

This work reports a facile novel approach to prepare asymmetric poly(vinylidene fluoride)/polystyrene (PVDF/PS) composite latex particles with controllable morphologies using one-step soap-free seeded emulsion polymerization, i.e., surface-initiated single electron transfer radical polymerization (SET-RP) of styrene (St) at the surface of PVDF seed particles. It was observed that the morphology...

Case Report A 13 year old boy from a healthy non-consanguineous family suffers from severe autoinflammatory symptoms (persistent fever, polyserositis, urticaria, arthritis, developmental delay, deafness and hepatosplenomegaly) since his first year of life. Based on clinical presentation and genotype (heterozygous mutation (CAG)>Lysin (AAG)-p. Gln703Lys/Q705K substitution in Exon 3 of NLPR3) he ...

Abstract We describe a simplified method to synthesize film forming polymer Janus particles by phase separation during RAFT-based free radical emulsion polymerization. Fully crosslinked snowman- or football-shaped polystyrene (PSJPs) were first produced in one-step batch process using amphiphilic triblock macro-RAFT copolymers as stabilizers. Such turn employed seeds continuous polymerization w...

Abstract Colloidal particles fabricated with anisotropic interactions have emerged as building blocks for designing materials various nanotechnological applications. We used coarse-grained Langevin dynamics simulations to probe the morphologies of self-assembled structures formed by lobed decorated functional groups. tuned between groups investigate their effect on porosity different shapes (sn...
