In a recent paper [Phys. Rev. Lett. 97, 070401 (2006)] the transition rate of magnetic spin-flip of a neutral two-level atom trapped in the vicinity of a thick superconducting body was studied. In the present paper we will extend these considerations to a situation with an atom at various distances from a dielectric film. Rates for the corresponding electric dipole-flip transition will also be ...

Fuzzy functional dependency (FFD) is a kind of semantic knowledge and can be discovered from a large volume of business data. Sectional FFD and Attribute FFD are discussed so as to reflect semantics of the business world and express useful information that is natural for people to comprehend. The experimental results on an insurance data set show that the proposed method can extract knowledge e...

OBJECTIVES To ascertain the dynamic stretch effects of flexibility of the hamstrings on lumbar spine and pelvic kinematics. BACKGROUND Tight hamstrings are positively correlated with low back pain. However, it is unclear how flexibility of the hamstrings affects spino-pelvic rhythm. METHODS Twelve healthy men participated in the study. The straight leg raising (SLR) angle, finger floor dist...

[Purpose] The aim of this study was to compare immediate effects between new medical stretching (NMS) and conventional medical stretching (CMS) techniques on Hamstrings flexibility. [Subjects and Methods] Thirteen healthy adult males, with finger floor distance (FFD) less than zero centimeter, without known musculoskeletal and neurological impairment in spine or lower extremities, were included...

Fox-Fordyce Disease (FFD) is a rare, chronic, pruritic, inflammatory disorder of apocrine glands. It is characterized by dome-shaped, firm, discrete, skin-colored, and monomorphic perifollicular papules. The most common sites of involvement are axillae and anogenital and periareolar regions which are rich in apocrine sweat glands. Treatment is difficult. Topical, intralesional steroids, topical...

UNLABELLED Real-time flow simulation is crucial for emergency management in buildings, such as fire and accidental or intentional release of chemical/biological agents (contaminants). The simulation results can then be used to impose proper measures to minimize casualties. Computational fluid dynamics (CFD) is accurate, but too time-consuming. Nodal models are fast, but not informative. To obta...

Scale-invariance, good localization and robustness to noise distortions are the main properties that a local feature detector should possess. Most existing detectors find excessive unstable points increase number of keypoints be matched computational time matching step. In this paper, we show robust accurate exist in specific scale-space domain. To end, first formulate superimposition problem i...

This paper presents PB-FFD, a novel, interactive, point-based technique for performing free-form deformation of polygonal meshes. First, a volumetric deformation space is de ned as the linear combination of overlapping, ellipsoidal radial basis functions (EBFs) of compact support. Mesh vertices are then parameterized with respect to local coordinate frames centered over the origins of the EBFs....
