Electrically driven single electron spin resonance in a slanting Zeeman field (2008)

Pioro-Ladriere, M., Obata, T., Tokura, Y., Kubo, T., Yoshida, K., ...

The rapidly rising fields of spintronics and quantum information science have led to a strong interest in developing the ability to coherently manipulate electron spins. Electron spin resonance (ESR)...

Micro-magnets for coherent control of spin-charge qubit in lateral quantum dots (2006)

Pioro-Ladriere, M., Tokura, Y., Obata, T., Kubo, T., Tarucha, S.

A lateral quantum dot design for coherent electrical manipulation of a two-level spin-charge system is presented. Two micron-size permanent magnets integrated to high-frequency electrodes produce a...

Rotation-induced 3D vorticity in 4He superfluid films adsorbed on a porous glass (2004)

Fukuda, M., Zalalutdinov, M. K., Kovacik, V., Minoguchi, T., Obata, T., Kubota, M., ...

Detailed study of torsional oscillator experiments under steady rotation up to 6.28 rad/sec is reported for a 4He superfluid monolayer film formed in 1 micrometer-pore diameter porous glass. We found...

Calculation of the Phase Field of a Vortex Pair on the Surface of a Multiplly Connected Substrate (2002)

Obata, T., Kubota, M.

The vortex pair phase field is calculated, through a solution of the Laplace equation, for a superfluid film adsorbed on the surface of a model 3D connected porous medium. A number of different...

Introduction of Modern Subsystems at the KEK Injector-linac (2001)

Kamikubota, N., Furukawa, K., Kusano, S., Obata, T.

As an accelerator control system survives over several years, it is often the case that new subsystems are introduced into the original control system. The control system for the KEK...

Beam Feedback Systems and BPM Read-out System for the Two-Bunch Acceleration at Kekb Linac (2001)

Furukawa, K., Kamikubota, N., Suwada, T., Obata, T.

In order to double the positron injection rate into the KEKB ring, a two-bunch acceleration scheme has been studied at the linac, in which bunches separated by 96 ns are accelerated in 50 Hz. In this...

Flattening modulus of a neutron star by rotation and magnetic field (2000)

Konno, K., Obata, T., Kojima, Y.

We calculated the ellipticity of the deformed star due to the rotation or magnetic field. These two effects are compared to each other within general relativity. It turned out that the magnetic...

Deformation of relativistic magnetized stars (1999)

Konno, K., Obata, T., Kojima, Y.

We formulate deformation of relativistic stars due to the magnetic stress, considering the magnetic fields to be perturbations from spherical stars. The ellipticity for the dipole magnetic field is...

Secondary ion mass spectrometry round-robin study for relative sensitivity factors in gallium arsenide (1998)

Homma, Y., Tohjou, F., Masamoto, A., Shibata, M., Shichi, H., Yoshioka, Y., ...

Round-robin studies on relative sensitivity factors (RSFs) in secondary ion mass spectrometry (SIMS) were conducted using bulk GaAs samples uniformly doped with various impurity elements. A total of...

Fine Structural Changes in Barley Aleurone Cells During Gibberellic Acid-induced Enzyme Secretion (1979)

OBATA, T.

The fine structure of barley aleurone cells was studied in the enzyme secretion phase. An ultrastructural feature of this phase is the formation of stacked rough endoplasmic reticulum (rER), for such...

Stimulation of alpha 1-adrenoceptors and protein kinase C-mediated activation of ecto-5'-nucleotidase in rat hearts in vivo.

Sato, T, Obata, T, Yamanaka, Y, Arita, M

1. To determine whether protein kinase C (PKC)-mediated activation of ecto-5'-nucleotidase would increase interstitial adenosine concentrations in the rat heart in vivo, we made use of the...

Sato, T, Obata, T, Yamanaka, Y, Arita, M

1. To determine whether protein kinase C (PKC)-mediated activation of ecto-5'-nucleotidase would increase interstitial adenosine concentrations in the rat heart in vivo, we made use of the...

DNA methylation and histone deacetylation associated with silencing DAP kinase gene expression in colorectal and gastric cancers

Satoh, A, Toyota, M, Itoh, F, Kikuchi, T, Obata, T, Sasaki, Y, ...

Death-associated protein kinase is a positive regulator of programmed cell death induced by interferon γ. To investigate the role of epigenetic inactivation of death-associated protein kinase in...
