BACKGROUND Participation rate and response rate are key issues in a cross sectional large-scale epidemiological study. The objective of this paper is to describe the study population and to evaluate participation and response rate as well as the key nutritional status variables in male and female adolescents involved in the HELENA study. METHODS A multi-stage random cluster sampling with a ta...
The concept of spin models was introduced by V.F. Jones in 1989. K. Kawagoe, A. Munemasa and Y. Watatani generalized it by removing the condition of symmetry. Recently E. Bannai and E. Bannai further generalized the concept of spin models, to give four-weight spin models or generalized spin models. Before this, F. Jaeger first pointed out the relation between spin models and association schemes...
aim: substance abuse is a substantial threat and problem to public health. the goal of drug abuse treatment is to return people to a productive normal situation in the family, workplace, and community. treatment dropout is one of the major problems, encountered by the treatment programs. the maintenance of treatment is associated with retention in treatment, and many factors are associated with...
We investigate the steady-state phase diagram of dissipative spin-1/2 XYZ model on a two-dimensional triangular lattice, in which each site is coupled to local environment. By means cluster mean-field approximation, we find that phases system are rather rich, particular there exist various types nonuniform antiferromagnetic due geometrical frustration. As short-range correlations included analy...
The scaling of CMOS devices is about to reach fundamental limits, and this prompts the development of new technologies in semiconductor industry. Spin-based electronics or spintronics is considered as one of the alternatives in ‘beyond CMOS’ research. Silicon, the main element of microelectronics, appears to be the perfect material for spin-driven applications. Purely electrical spin injection ...
We report a technology to form human embryoid bodies (hEBs) from singularized human embryonic stem cells (hESCs) without the use of the p160 rho-associated coiled-coil kinase inhibitor (ROCKi) or centrifugation (spin). hEB formation was tested under four conditions: +ROCKi/+spin, +ROCKi/-spin, -ROCKi/+spin, and -ROCKi/-spin. Cell suspensions of BG01V/hOG and H9 hESC lines were pipetted into non...
We generalize the Elliott-Yafet (EY) theory of spin relaxation in metals with inversion symmetry for the case of large spin-orbit coupling (SOC). The EY theory treats the SOC to the lowest order but this approach breaks down for metals of heavy elements (such as e.g. caesium or gold), where the SOC energy is comparable to the relevant band-band separation energies. The generalized theory is pre...
Successful realization of polarized Drell-Yan physics program is one of the main goals of the second stage of the COMPASS experiment. Drell-Yan measurements with high energy (190 GeV/c) pion beam and transversely polarized NH3 target have been initiated by a pilot-run in the October 2014 and will be followed by 140 days of data taking in 2015. In the past twelve years COMPASS experiment perform...
