TL;DR: The energy-dependent disappearance of nu(mu), which the authors presume have oscillated to nu(tau), is observed in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment.
Abstract: We present results for nu(mu) oscillation in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced nu(mu) beam with a mean energy of 1.3 GeV directed at the Super-Kamiokande detector. We observed the energy-dependent disappearance of nu(mu), which we presume have oscillated to nu(tau). The probability that we would observe these results if there is no neutrino oscillation is 0.0050% (4.0 sigma).

TL;DR: The issue of motor selection to arrange multiple movements in an appropriate temporal order is dealt with, rather than the issue of constructing spatio-temporal structures in a single action.
Abstract: Much of our normal behavior depends on the sequential execution of multiphased movements, or the execution of multiple movements arranged in a correct temporal order. This article deals with the issue of motor selection to arrange multiple movements in an appropriate temporal order, rather than the issue of constructing spatio-temporal structures in a single action. Planning, generating, and controlling the sequential motor behavior involves multiple cortical and subcortical neural structures. Studies on human subjects and nonhuman primates, however, have revealed that the medial motor areas in the frontal cortex and the basal ganglia play particularly important roles in the temporal sequencing of multiple movements. Cellular activity observed in the supplementary and presupplementary motor areas while performing specifically designed motor tasks suggests the way in which these areas take part in constructing the time structure for the sequential execution of multiple movements.

TL;DR: Continuous Sic fibers with a tensile strength of 350 kg/mm2 and a Young's modulus of 30 tons/mm 2 were synthesized from an organometallic polymer as discussed by the authors.
Abstract: Continuous Sic fibers with a tensile strength of 350 kg/mm2 and a Young's modulus of 30 tons/mm2 were synthesized from an organometallic polymer. Continuous fibers were first obtained by heat-treating a polycarbosilane polymer which had been synthesized from dimethyldichlorosilane. The fiber, which contains ultrafine-grain crystallites of β-Sic, has no fiber texture measurable by X-ray diffraction and high-voltage electron microscopy.

TL;DR: In this paper, the authors theoretically study the optical absorption property of twisted bilayer graphenes with various stacking geometries and demonstrate that the spectroscopic characteristics serve as a fingerprint to identify the rotation angle between two layers.
Abstract: We theoretically study the optical absorption property of twisted bilayer graphenes with various stacking geometries and demonstrate that the spectroscopic characteristics serve as a fingerprint to identify the rotation angle between two layers. We find that the absorption spectrum almost continuously evolves in changing the rotation angle, regardless of the lattice commensurability. The spectrum is characterized by series of peaks associated with the van Hove singularity, and the peak energies systematically shift with the rotation angle. We calculate the optical absorption in two frameworks: the tight-binding model and the effective continuum model based on the Dirac equation. For small rotation angles, less than ${10}^{\ensuremath{\circ}}$, the effective model well reproduces the low-energy band structure and the optical conductivity of the tight-binding model and, also, explains the optical selection rule analytically in terms of the symmetry of the effective Hamiltonian.
