Establishment of Cp Violation in B Decays

■ Abstract Until recently, CP violation had been observed only in kaon decays. In order to conclusively interpret CP violation and test whether it can be explained in the framework of the Cabibbo-Kobayashi-Maskawa matrix, two asymmetric B factories, KEK-B and PEP-II, were constructed in the past decade. Recent measurements with the two detectors at these B factories clearly established large CP...

Kek-6: A truncated-Trk-like receptor for Drosophila neurotrophin 2 regulates structural synaptic plasticity

Neurotrophism, structural plasticity, learning and long-term memory in mammals critically depend on neurotrophins binding Trk receptors to activate tyrosine kinase (TyrK) signaling, but Drosophila lacks full-length Trks, raising the question of how these processes occur in the fly. Paradoxically, truncated Trk isoforms lacking the TyrK predominate in the adult human brain, but whether they have...

K2k (kek to Kamioka) Neutrino-oscillation Experiment at Kek-ps * )

In recent years, several underground neutrino observatories 1) 3) have reported that the atmospheric neutrino ratio, R ≡ (νμ + ν̄μ)/(νe + ν̄e), is significantly smaller than the theoretical expectations. This “atmospheric neutrino anomaly” can be explained by a neutrino oscillation hypothesis with an oscillation parameter region of ∆m2 ∼ 10−2eV2 and sin 2θ ∼ 1. The atmospheric neutrino anomaly ha...

Sufism in the Western History : A Primary Outline

The phenomenon of Western Sufi teachers is unique, not just because of the individuals themselves, though they are certainly fascinating, but because of what they represent: the flowering of the Western genius, which has discovered Eastern traditions, absorbed them and in the process changed them and been changed by them. This paper is a primary outline of the main contours of this phenomenon, ...
