Odderon induced contributions to exclusive photoproduction of π • , f 2 (1270) and a 2 (1320) have been searched for at HERA, using the multiphoton decays of these mesons. No indication for such contributions was found, in a kinematic region defined by the average photon-proton centre-of-mass energy W = 200 − 215 GeV, photon virtual-ities Q 2 < 0.01 GeV 2 and 0.02 GeV 2 < |t| < 0.3 GeV 2 , wher...

We calculate partial widths of the γγ decay of the tensor qq̄ states a2(1320), f2(1270), f2(1525), their radial excitations a2(1660), f2(1640), f2(1800) as well as F2qq̄ states. Calculations are performed in the framework of the same approach which was used before for the study of radiative decays f0(980) → γγ, a0(980) → γγ and φ(1020) → γf0(980): the assumption made is that of qq̄ structure of f0...

The United States of America has adopted the SHA-1 hash algorithm described herein as a Federal Information Processing Standard. The purpose of this document is to make it conveniently available to the Internet community. Most of the text herein was taken by the authors from FIPS 180-1. Only the C code implementation is "original" and that is similar to the MD2/MD4/MD5 RFCs. D. Eastlake 3rd, P....

Research in the Limpopo Valley has documented over 500 Middle Iron Age sites (AD 900–1320) relevant to origins of Mapungubwe – capital first indigenous state southern Africa. Fifteen new accelerator mass spectrometry (AMS) dates from 11 these archaeological establish boundaries ceramic facies that form culture-history framework for such diverse topics as land use, ethnic stratification, populat...

Keloids are disfiguring, inflammatory fibroproliferative growths that expand beyond the borders of cutaneous insults. To elucidate regulatory mechanisms in keloid pathogenesis, we performed transcriptional profiling biopsies from keloids as well adjacent non-lesional (NL) skin on African-American participants (n=3). We identified 344 differentially expressed genes (DEGs) between and normal -- 2...
