The presence of peripheral arterial disease substantially increases the risk for both morbidity and mortality among end-stage renal disease patients. Low-density lipoprotein (LDL) apheresis has been also applied for the treatment of peripheral arterial disease to reduce LDL levels, resulting in the improvement of the blood flow to the ischemic limbs. Inâ€¦ (More)

In the Fractional Quantum Hall state, we introduce a bi-local mean field and get vortex mean field solutions. Rotational invariance is imposed and the solution is constructed by means of numerical self-consistent method. It is shown that vortex has a fractional charge, a fractional angular momentum and a magnetic field dependent energy. In Î½ = 1/3 state, weâ€¦ (More)

Using a mean field theory on the von Neumann lattice, we study compressible anisotropic states around Î½ = l+ 1/2 in the quantum Hall system. The Hartree-Fock energy of the UCDW are calculated self-consistently. In these states the unidirectional charge density wave (UCDW) seems to be the most plausible state. We show that the UCDW is regarded as aâ€¦ (More)

In recent experiments, highly anisotropic states are observed in the half-filled third and higher Landau levels[1]. In the half-filled second Landau level the fractional quantum Hall effect (FQHE)[2] and transition to the highly anisotropic state are observed[3]. Theoretically the anisotropic states are regarded as stripe states[4] or unidirectional chargeâ€¦ (More)

Under general assumptions, we present a low-energy effective action for the quantum Hall state when edges exist. It is shown that the chiral edge current is necessary to make the effective action to be gauge invariant. However the chiral edge current is irrelevant to the Hall current. The exactly quantized value of Ïƒxy is observed only when the Hall currentâ€¦ (More)

We study spin and charge striped states at the half-filled high Landau level in the zero Zeeman energy limit using a HartreeFock approximation. It is shown that a ferromagnetic striped Hall state is more stable than the antiferromagnetic striped state or charge striped state. We calculate the collective excitations using the single mode approximation.

Applying a bi-local mean field approximation to the fractional quantum Hall state of Î½ = 1/3, we obtain charged and neutral vortex mean field solutions numerically. We calculate the mean field energy and the fluctuation corrections. The charged vortex has a fractional charge and a fractional angular momentum. The neutral vortex is a bound state of twoâ€¦ (More)

SjÃ¶gren's syndrome is not one of the forty-five diseases included in the incurable disease treatment research project funded by the government. However, it is approved as a designated incurable disease for government funded treatment in Tokyo. The criteria of approval are based on diagnostic criteria revised in 1999. Complications and other factors areâ€¦ (More)

Bi-local mean field theory is applied to one dimensional quantum liquid with long range 1/r2 interaction, which has exact ground state wave function. We obtain a mean field solution and an effective action which expresses a long range dynamics. Based on them the ground state energy and correlation functions are computed. The ground state energy agreesâ€¦ (More)

Formulation of quantum Hall dynamics using von Neumann lattice of guiding center coordinates is presented. A topological invariant expression of the Hall conductance is given and a new mean field theory of the fractional Hall effect based on flux condensation is proposed. Because our mean field Hamiltonian has the same form as Hofstadter Hamiltonian, it isâ€¦ (More)
