In this article we consider a plate made of by two types of materials: a part is conservative and the other dissipative. We show that the dissipation produced for the second part is strong enough to obtain the uniform decay of the energy. moreover, we found that the rate of decay of the solutions depend on behavior of the dissipative term in a neighborhood of zero, that is, for a linear dissipa...

The D0 meson can decay to the wrong sign K+ π state either through a doubly Cabibbo suppressed decay or via mixing to the D0 state followed by the Cabibbo favoured decay D0 → K+π−. We measure the rate of wrong sign decays relative to the Cabibbo favoured decay to (0.383 ± 0.044 ± 0.022)% and give our sensitivity to a mixing signal.

The intrinsic decay rate of orthopositronium formed in SiO2 powder is measured using the direct 2γ correction method such that the time dependence of the pick-off annihilation rate is precisely determined using high energy-resolution germanium detectors. As a systematic test, two different types of SiO2 powder are used with consistent findings. The intrinsic decay rate of orthopositronium is fo...

The electron neutrino mass has been measured in several tritium beta decay experiments. These experiments are sensitive to a small neutrino mass because the energy release of the decay is small. But the very smallness of the energy release implies that the Coulomb interactions of the slowly moving emitted beta electron are relatively large. Using field theoretic techniques, we derive a systemat...

glassy carbon (gc) is the most commonly used carbon-based electrode in the analytical laboratory. because of the high background current and low electrode response, modification of this electrode can be done by various materials and techniques. an ionic liquid (il), 1-methyl-3-(3-trimethoxysilyl propyl) imidazoliumbis (trifluoromethylsulfonyl) imide, was covalently cross linked onto the gc surf...
