We present S, a system that implicitly captures the process and products of Web investigations (exploratory searches involving multiple queries). This automatically-created, persistent representation of an investigation enables future review and continuation of suspended search activities. This persistent representation can reduce unnecessary re-execution of queries and enable users to quickly ...
We construct various examples of 14 -BPS giant gravitons embedded into the type IIB supergravity background AdS3 × S3 + × S3 − × S1 with pure R-R flux: two D1brane giants wrapping 1-cycles in AdS3 and S 3 + × S3 −, and one D5-brane giant wrapping a 4-cycle in S3 + × S3 − and the S1. These D-branes are supported by angular momenta αP on one 3-sphere and (1 − α)P on the other. We then construct a...
S3 peptide, derived from the Sushi 3 domain of Factor C, which is the lipopolysaccharide (LPS)-sensitive serine protease of the horseshoe crab coagulation cascade, was shown previously to harbor antimicrobial activity against Gram-negative bacteria. However, the mechanism of action remains poorly understood at the molecular level. Here we demonstrate that the intermolecular disulfide bonding of...
BACKGROUND New generation transcatheter heart valves (THV) may improve clinical outcomes of transcatheter aortic valve implantation. METHODS AND RESULTS In a nationwide, prospective, multicenter cohort study (Swiss Transcatheter Aortic Valve Implantation Registry, NCT01368250), outcomes of consecutive transfemoral transcatheter aortic valve implantation patients treated with the Sapien 3 THV ...
In [l] Berstein and Ganea define the nilpotence of an ü-space to be the least integer » such that the »-commutator is nullhomotopic. We prove that S3 with the usual multiplication is 4 nilpotent. Let X be an ii-space. The 2-commutator c2: XXX—>X is defined by c2(x, y) =xyx~1y~1 where the multiplication and inverses are given by the ü-space structure of X. The »-commutator cn: X"-+X is defined i...
