We resum to next-to-leading order the distribution in the ratio of the invariant hadron mass mX to the total hadron energy EX and the distribution in mX in the semileptonic decays B → Xulν. By expanding our formulas, we obtain the coefficients of all the infrared logarithms at O(αS) and of the leading ones at O(α 3 S). We explicitly show that the relation between these semileptonic spectra and ...

Let Γg,n, for 2g − 2 + n > 0, be the Teichmüller group of an n-punctured genus g compact Riemann surface Sg,n and let Γ̂g,n be its profinite completion. There is a natural homomorphism from the Galois cohomology of Γ̂g,n, with coefficients in a discrete torsion Γ̂g,n-module, to the cohomology of the discrete group Γg,n, with induced coefficients. The main result of this paper is that this map is a...

The paper assumes a continuum of two period-lived agents; agents are identical except for inherited income. Young agents allocate their inheritance between consumption and investment in human capital under uncertainty. In the second period they receive a wage proportional to the accumulated human capital and invest in offspring. Two main results arise: a low earning per unit of human capital le...

Il medico e la malattia: la scienza di Ippocrate

which insight into the condition is totally absent, is far more dangerous than the examples of anaemia, heart failure, or gall-bladder disease that are considered here. It is a consideration to bear in mind in reading the final chapter in which Park discusses the implications for the future. His conclusions are not comforting. Now, it is true, constant exposure by the media, especially televisi...
