Forward photon energy spectrum at LHC 7 TeV p-p collisions measured by LHCf
Abstract The LHCf experiment is one of the LHC forward experiments. The aim is to measure the energy and the transverse momentum spectra of photons, neutrons and π 0 's at the very forward region (the pseudo-rapidity range of η > 8.4 ), which should be critical data to calibrate hadron interaction models used in the air shower simulations. LHCf successfully operated at s = 900 GeV and s = 7 TeV proton–proton collisions in 2009 and 2010. We present the first physics result, single photon energy spectra at s = 7 TeV proton–proton collisions and the pseudo-rapidity ranges of η > 10.94 and 8.81 η 8.9 . The obtained spectra were compared with the predictions by several hadron interaction models and the models do not reproduce the experimental results perfectly

The 5-Ketofructose Reductase of Gluconobacter sp. Strain CHM43 Is a Novel Class in the Shikimate Dehydrogenase Family
A limited number of species of acetic acid bacteria, such as
Gluconobacter
sp. strain CHM43, produce 5-ketofructose, a potential low-calorie sweetener, at a high yield. Here, we show that an NADPH-dependent 5-ketofructose reductase (KFR) is involved in 5-ketofructose degradation, and we characterize this enzyme with respect to its structure, phylogeny, and function
