On the general action of boundary (super)string field theory (2008)
Ishida, Akira, Teraguchi, Shunsuke
We reconstruct boundary superstring field theory via boundary states. After a minor modification of the fermionic two-form, all the equations needed for Batalin-Vilkovisky formulation are simply...
Tachyon Vacuum Solution in Open String Field Theory with Constant B Field (2008)
Ishida, Akira, Kim, Chanju, Kim, Yoonbai, Kwon, O-Kab, Tolla, D. D.
We show that Schnabl's tachyon vacuum solution is an exact solution of the equation of motion of Witten's open bosonic string field theory in the background of constant antisymmetric two-form field....
Negative-Tension Branes and Tensionless 1/2 Brane in Boundary Conformal Field Theory (2008)
Ishida, Akira, Kim, Chanju, Kim, Yoonbai, Kwon, O-Kab
In the framework of boundary conformal field theory we consider a flat unstable D$p$-brane in the presence of a large constant electromagnetic field. Specifically, we study the case that the...
Lower Dimensional Branes in Boundary Conformal Field Theory (2008)
Ishida, Akira, Kim, Yoonbai, Kim, Chanju, Kwon, O-Kab
In the presence of constant background electromagnetic fields, we discuss three types of exactly marginal boundary tachyon operators for static kinks in boundary conformal field theory. Functional...
BPS Limit of Multi- D- and DF-strings in Boundary String Field Theory (2007)
Go, Gyungchoon, Ishida, Akira, Kim, Yoonbai
A BPS limit is systematically derived for straight multi- D- and DF-strings from the D3D3bar system in the context of boundary superstring field theory. The BPS limit is obtained in the limit of thin...

Homogeneous Rolling Tachyons in Boundary String Field Theory (2006)
Ishida, Akira, Kim, Yoonbai, Kouwn, Seyen
We study decay of a flat unstable D$p$-brane in the context of boundary string field theory action. Three types of homogeneous rolling tachyons are obtained without and with Born-Infeld type...
Tachyon condensation in unbalanced D-anti D system (2006)
Ishida, Akira, Uehara, Shozo, Yada, Tomoki
The tachyon condensation is studied in asymmetric D-anti D systems. Taking a system of two pairs of D5-anti D5 in type IIB superstring theory in the background of large N D5-branes, we show that one...
Tratamento cirúrgico do quadril displásico inveterado (2006)
Dobashi,Eiffel T., Kiyohara,Robinson Toshimitsu, Matsuda,Marcelo Mitsuro, Milani,Carlo, Kuwajima,Sérgio Satoshi, Ishida,Akira
Avaliamos 50 pacientes (57 quadris) com Displasia do desenvolvimento do Quadril Inveterada, divididos em 2 grupos de acordo com o tratamento aplicado. O grupo A foi constituído por 20 pacientes (24...

Rolling down to D-brane and tachyon matter (2003)
We investigate the spatially inhomogeneous decay of an unstable D-brane and construct an asymptotic solution which describes a codimension one D-brane and the tachyon matter in boundary string field...
Gauge Fields on Tachyon Matter (2002)
We study the rolling tachyon including the gauge fields in boundary string field theory. We show that there are no plane wave solutions for the gauge fields for large time. The disappearance of the...
O autor analisa os resultados clinicos e radiograficos de 32 pacientes (37 quadris) portadores da DLCP e submetidos a osteotomia de Salter no periodo de 1979 a 1992. Vinte e quatro pacientes eram do...
Aluminized Coatings on Titanium Alloys and TiAl Intermetallic Compound. (1998)
An investigation of aluminized coatings on titanium alloys and TiAl intermetallic compound is presented. The aluminizing was carried out by pack cementation at temperatures between 1073 and 1273 K....

Left ventricular preload reserve in preterm infants with patent ductus arteriosus
Takahashi, Yasushi, Harada, Kenji, Ishida, Akira, Tamura, Masamichi, Takada, Goro
The left ventricular Frank-Starling response was studied in 15 preterm infants, less than 1500 g birth weight, and in 16 fullterm infants with patent ductus arteriosus. Left ventricular end diastolic...
