Neurons destined for each region of the neocortex are known to arise approximately in an "inside-to-outside" sequence from a pseudostratified ventricular epithelium (PVE). This sequence is initiated rostrolaterally and propagates caudomedially. Moreover, independently of location in the PVE, the neuronogenetic sequence in mouse is divisible into 11 cell(More)
Neuronogenesis in the neocortical pseudostratified ventricular epithelium (PVE) is initiated rostrolaterally and progresses caudo-medially as development progresses. Here we have measured the cytokinetic parameters and the fractional neuronal output parameter, Q, of laterally located early-maturing regions over the principal embryonic days (E12-E15) of(More)

TAMA300, an interferometric gravitational-wave detector with 300-m baseline length, has been developed and operated with sufficient sensitivity to detect gravitational-wave events within our galaxy and sufficient stability for observations; the interferometer was operated for over 10 hours stably and continuously. With a strain-equivalent noise level of h(More)
Cerebral wall from embryonic day 13 mice was cultured in a three-dimensional collagen matrix in defined, serum-free medium. The cerebral wall retained its normal architecture, including the radial glial fiber system, for up to 19 h in culture. The cell cycle was initially blocked at the S/G2/M and the G1/S phase transitions, resulting in a transient(More)
We present new high-resolution (∼0. ′′09) H-band imaging observations of the circumstellar disk around the T Tauri star SU Aur. Our observations with Subaru-HiCIAO have revealed the presence of scattered light as close as 0. ′′15 (∼20 AU) to the star. Within our image, we identify bright emission associated with a disk with a minimum radius of ∼90 AU, an(More)
Adenosine 3',5'-cyclic monophosphate (cAMP) is formed from adenosine triphosphate at pH 8 and 50 degrees C by use of lanthanide ions. Pr3+ and La3+ are the most active. The cAMP formation is more efficient at higher pH, where the mixture is made homogeneous by the addition of beta-cyclodextrin. The potential functioning of lanthanide ions as the catalytic(More)
A high angular resolution near-infrared polarized-intensity image of the GG Tau A binary system was obtained with the Subaru Telescope. The image shows the circumbinary disk scattering the light from the central binary. The azimuthal profile of the polarized intensity of the circumbinary disk is roughly reproduced by a simple disk model with the(More)
A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavelengths requires baselines up to ∼15 km. To develop and test this capability, a Long Baseline Campaign (LBC) was carried out from 2014 September to late November, culminating in(More)
