Abstract
The exclusive reaction γp→K(+)π(-)Σ(+) was measured for the first time using linearly polarized photons at beam energies from 1.85 to 2.96 GeV. Angular distributions in the rest frame of the K(+)π(-) system were fitted to extract spin-density matrix elements of the K(*0) decay. The measured parity spin asymmetry shows that natural-parity exchange is dominant in this reaction. This result clearly indicates the need for t-channel exchange of the κ(800) scalar meson.

Abstract
An efficient and low-noise 1.244-GHz gating InGaAs single-photon avalanche photodiode (SAPD) was developed for a high-speed quantum key distribution (QKD) system. An afterpulsing probability of 0.61% and a dark count probability per gate of 0.71 ×10-6 were obtained at a detection efficiency of 10.9% for 1.55-µm photons. Furthermore, our SAPD successfully coped with high detection efficiency (≤ 25%) and quite low afterpulsing noise (≤ 3% for ≤ 25% efficiency) at the same time. Its potential was verified using the actual QKD setups installed over a metropolitan area network.

Abstract
We discuss our estimates of the performance of a superconducting single photon detector (SSPD) in a high speed quantum key distribution (QKD) system. We find that at high repetition operation reflections from the readout circuit at room temperature causes an afterpulse-like phenomenon, and drastically increases the quantum bit error rate (QBER). Such effects are not seen during low frequency operation. By using an amplifier with a small reflection coefficient S11, we succeed in reducing the afterpulse-like phenomenon and increasing a secure key rate.

Abstract
Sulfatide (ST) is a sphingolipid with an important role in the central nervous system as a major component of the myelin sheath. ST contains a structurally variable ceramide moiety, with a fatty acid substituent of varying carbon-chain length and double-bond number. Hydroxylation at the α-2 carbon position of the fatty acid is found in half the population of ST molecules. Recent genetic studies of fatty acid 2-hydroxylase (FA2H) indicate that these hydroxylated sphingolipids influence myelin sheath stability. However, their distribution is unknown. Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) enables the analysis of distinct distributions of individual ST molecular species in tissue section. We examined human cerebral cortex tissue sections with MALDI-IMS, identifying and characterizing the distributions of 14 ST species. The distribution analysis reveals that the composition ratios of non-hydroxylated/hydroxylated STs are clearly reversed at the border between white and gray matter; the hydroxylated group is the dominant ST species in the gray matter. These results suggest that hydroxylated STs are highly expressed in oligodendrocytes in gray matter and might form stable myelin sheaths. As a clinical application, we analyzed a brain with Alzheimer's disease (AD) as a representative neurodegenerative disease. Although previous studies of AD pathology have reported that the amount of total ST is decreased in the cerebral cortex, as far as the compositional distributions of STs are concerned, AD brains were similar to those in control brains. In conclusion, we suggest that MALDI-IMS is a useful tool for analysis of the distributions of various STs and this application might provide novel insight in the clinical study of demyelinating diseases.

Abstract
A secure communication network with quantum key distribution in a metropolitan area is reported. Six different QKD systems are integrated into a mesh-type network. GHz-clocked QKD links enable us to demonstrate the world-first secure TV conferencing over a distance of 45km. The network includes a commercial QKD product for long-term stable operation, and application interface to secure mobile phones. Detection of an eavesdropper, rerouting into a secure path, and key relay via trusted nodes are demonstrated in this network.
