Semileptonic decays of D-mesons into scalar hadronic states are investigated. Two extreme cases are considered: a) the meson decays directly into an uncorrelated scalar state of two two mesons and b) the decay proceeds via resonance formation. QCD sum rules including instanton contributions are used to calculate total and differential decay rates under the two assumptions. PACS Numbers : 12.38....

Using the most general, model independent effective Hamiltonian, the branching ratio of the B → Kll decay, when K meson is longitudinally or transversally polarized, is presented. The dependence of the branching ratio on the new Wilson coefficients, when K meson is polarized, is studied. It is observed that the branching ratio is very sensitive to the vector and tensor type interactions, which ...

Since the pioneer efforts of Banyai6 there have emerged only a few reports up to relative recency. Since 1947 publications by Mitchell et al.,’ Trimble et al.,8 Hurst et al.’4 and several others have contributed notably to further clarification of the results which have been consistently good, particularly in the face of many instances of far advanced disease wherein prognosis once was held as ...

It was already well known since the sanatoria period (Germany, 1857) when treatment against TB consisted of good food, rest, sun, and fresh air that about half of TB cases recovered almost spontaneously. Robert Koch’s discovery of Mycobacterium tuberculosis in 1882, Carlo Forlanini introduced the artificial pneumothorax in 1907 [1] and streptomycin was introduced at the end of the Second World ...

From its initial development by Carlo Forlanini at the end of the nineteenth century until the advent of antibiotics in the 1940s, artificial pneumothorax was one of the most widely used treatments for pulmonary tuberculosis. However, there were strongly held reservations about this therapy because of its risks and side effects. In the Soviet Union under Stalin, such uncertainties became instru...

Despite being set up in 1913 using a fund specifically earmarked for tuberculosis, the Medical Research Committee (renamed the Medical Research Council [MRC] in 1919) prioritised other areas of medical research. From 1920, the MRC did have three subcommittees concerned with tuberculosis: the Tuberculin Committee, the Bacteriology Committee and the Occupational Phthisis (pulmonary tuberculosis) ...

We find an analogy between turbulence and the dynamics of the continuous spontaneous localization model (CSL) of the wave function. The use of a standard white noise in the localization process gives Richardson’s t law for the turbulent diffusion, while the introduction of an affine noise in the CSL allows us to obtain the intermittency corrections to this law. PACS: 05.40.Fb, 03.65.Bz, 02.50.E...

The polarization measurement in the inclusive B decay provides us with a simple test of how much the long-distance final-state interaction takes place as the energy of the observed meson varies in the final state. We give the expectation of perturbative QCD for the energy dependence of the helicity fractions in a semiquantitative form. Experiment will tell us for which decay processes the pertu...

An implicit Lagrangian hydrodynamics code for general relativistic spherical collapse is presented. This scheme is based on an approximate linearized Riemann solver (Roe type scheme) and needs no artificial viscosity. This code is aimed especially at the calculation of the late phase of collapse-driven supernovae and the nascent neutron star, where there is a remarkable contrast between the dyn...

Thk study was stimulated through the observation, by one of us (L.H.H.) of the appearance of the picture of right-sided heart failure in two patients who had been receiving artificial pneumothorax. Our purpose was to see if we could detect, early in the course of collapse therapy, any evidences of right heart strain. In addition to clinical observations we employed certain laboratory procedures...
