This study examined the effects of electroencephalographic- (EEG-) driven photic stimulation on a case of depressive disorder, as measured by a psychometric test of mood states, EEG parameters, and several autonomic indices. The EEG-driven photic stimulation enhances the alpha rhythm of brain waves using photic signals, the brightness of which is modulated(More)
We present the first evidence of the decay B- --> tau- nu(tau), using 414 fb(-1) of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We detect the signal with a significance of 3.5 standard deviations including(More)
The spin, in-plane and out-of-plane orbital and magnetic dipole moments of almost purely interfacial Co atoms were directly determined for Au/2-monolayer Co nanoclusters/Au(111) by angle-dependent magnetic circular x-ray dichroism (MCXD) measurements. The field- and temperature-dependent MCXD evidences a ferromagnetic(FM)-to-superparamagnetic phase(More)
Equal amounts of matter and antimatter are predicted to have been produced in the Big Bang, but our observable Universe is clearly matter-dominated. One of the prerequisites for understanding this elimination of antimatter is the nonconservation of charge-parity (CP) symmetry. So far, two types of CP violation have been observed in the neutral K meson(More)
The dc oxygen-discharge cleaning of optical elements contaminated by synchrotron radiation has been studied for a variety of contamination levels, optical materials, electrode and reflecting-surface configurations, discharge powers, and exposure times. Cleaning with a proper electrode-surface configuration resulted in the removal of contaminant layers(More)
The capability of dc oxygen-discharge cleaning to resuscitate the efficiencies of mirrors and gratings contaminated by synchrotron radiation has been studied over the 100-1000-eV photon-energy range. The contamination- induced efficiency degradation was severe at the carbon K edge, even for a low contamination level. A large reduction in the mirror(More)
