We investigate the supersymmetric D-brane configurations in the pp-wave backgrounds proposed by Maldacena and Maoz. We study the surviving supersymmetry in a D-brane configuration from the worldvolume point of view. When we restrict ourselves to the background with N = (2, 2) supersymmetry and no holomorphic Killing vector term, there are two types of(More)
The borderline zone condition between normal aging and dementia is a major issue of concern. Although the term mild cognitive impairment (MCI) is popular, its prevalence and neuropsychological features have not been fully investigated. We investigated the prevalence and neuropsychological features for Clinical Dementia Rating (CDR) 0.5 and MCI. For normal(More)
Tea (Camellia sinensis (L.) O. Kuntze) is the world’s most popular beverage crop. However, to date, no core collection has been selected from worldwide germplasm resources on the basis of genotype data. In this study, we analyzed 788 tea germplasm accessions using 23 simple sequence repeat (SSR) markers. Our population structure analysis divided the(More)
BACKGROUND The borderline condition between health and dementia, defined as Clinical Dementia Rating (CDR) 0.5, should be detected for the possible prediction of dementia. Since the CDR requires information from collateral sources, it is difficult to rate people living alone. The aim is to develop a set of tests without collateral information for detecting(More)
BACKGROUND Several studies have reported that the prevalence of idiopathic normal-pressure hydrocephalus (iNPH) was between 0 and 5%. However, the precise prevalence in a community-based elderly population remains unclear. We investigated the prevalence of possible iNPH retrospectively using an age- and gender-stratified random sample database. METHODS(More)
We consider the supergravity backgrounds that correspond to supersymmetric Wilson line operators in the context of AdS/CFT correspondence. We study the gravitino and dilatino conditions of the IIB supergravity under the appropriate ansatz, and obtain some necessary conditions for a supergravity background that preserves the same symmetry as the(More)
We investigate Wilson loop operators in three-dimensional, N = 6 superconformal Chern-Simons theory dual to IIA superstring theory on AdS 4 × CP 3. A novelty of the Wilson loop operators is that, for a given Wilson loop contour, there are even and odd varieties under generalized spacetime parity. We assert that parity-even BPS Wilson loop is special and(More)
BACKGROUND Knee kinematics during pivoting activities are not well studied, but might provide insight critical to understanding the pathology of the anterior cruciate ligament deficient knee. The purpose of this study was to compare in vivo kinematics during weight bearing pivot and squat activities in patients with unilateral anterior cruciate ligament(More)
