v. dannon showed that spherical curves in e4 can be given by frenet-like equations, and he thengave an integral characterization for spherical curves in e4 . in this paper, lorentzian spherical timelike andspacelike curves in the space time 41 r are shown to be given by frenet-like equations of timelike andspacelike curves in the euclidean space e3 and the minkowski 3-space 31 r . thus, finding...

Blanchflower and Oswald (1994) have argued that, in regional data, the level of unemployment is related to the fevel of wages. This result is at variance with an application of the original Phillips curve to regional data, which would predict that the change in wages ought to be related to the unemployment rate. On the other hand, there is considerable empirical support for the expectations-aug...

The indocyanine green fluorescence imaging is a promising technique for sentinel node biopsy with advantages of dye-guided method, which is potentially safer, more convenient, and more cost-effective compared with the radioguided one. It could simplify the dye-guided method in both open and laparoscopic gastric cancer surgery, and possibly shortens the learning curve, which is one of the most c...

We prove the Hausdorff property of the Néron modle of the family of intermediate Jacobians which is recently defined by Green, Griffiths and Kerr assuming that the divisor at infinity is smooth. Using their result, this implies in this case the analyticity of the closure of the zero locus of an admissible normal function. The last assertion is also obtained by Brosnan and Pearlstein generalizin...

We prove the Hausdorff property at the monodromy invariant subspace of the Zucker extension of the family of intermediate Jacobians if the divisor at infinity is smooth. Using a recent theorem of Green, Griffiths and Kerr, it implies in this case the analyticity of the closure of the zero locus of an admissible normal function, generalizing a theorem of Brosnan and Pearlstein in the curve case ...

The ground state energy dispersion curve of a single mobile hole in the two-dimensional t-J model is studied numerically by means of the Green function Monte Carlo method on square lattices of various sizes up to 16 16. Transient estimation results show evidence of a gap of the order of 0:2 t, in the physical region of the model, between the energy value at k = (=2; =2), which corresponds to th...

BACKGROUND Bereavement is a condition which most people experience several times during their lives. A small but noteworthy proportion of bereaved individuals experience a syndrome of prolonged psychological distress in relation to bereavement. The aim of the study was to develop a clinical tool to identify bereaved individuals who had a prognosis of complicated grief and to propose a model for...
