We have obtained high-resolution position-velocity (PV) diagrams along the major axes of the central regions of nearby galaxies in the CO-line emission using the Nobeyama 45-m telescope and the Millimeter Array. Nuclear rotation curves for 14 galaxies have been derived based on the PV diagrams using the envelope-tracing method. The nuclear rotation curves for most of the galaxies show a steep r...

A novel method for the reduction of subthreshold slope below the room-temperature Boltzmann limit of 60 mV/dec for a field-effect transistor based on negative differential capacitance is proposed. This effect uses electric field induced electrostriction of a piezoelectric gate barrier of the transistor. The mechanism amplifies the internal surface potential over the applied gate voltage. This i...

We introduce three deenitions of the q-analogs of Motzkin numbers and illustrate some combinatorial interpretations of these q-numbers. We relate the rst class of q-numbers to the steep parallelogram polyominoes' generating function according to their width, perimeter and area. We show that this generating function is the quotient of two q-Bessel functions. The second class of q-Motzkin numbers...

The density collapse was observed in the improved confinement mode sustained by the hot cathode biasing in Tohoku University Heliac (TU-Heliac). The density profiles showed the steep gradient around the core plasma region before the collapse. The steep density profile collapsed accompanied with the bursting high frequency fluctuation (100 < f < 500 kHz), which had m = 2 ~ 3 poloidal mode number...

It is well known that the mass function for halos in CDM cosmology is a relatively steep power law (n(M) ∝ M) for low masses, possibly too steep to be consistent with observations. But how steep is the galaxy mass function? We have analyzed the stellar and gas mass functions of the first massive luminous objects formed in a ΛCDM universe, as calculated in the numerical simulation described in G...
