We consider a model for the decay B 0 → ρ 0 γ in which the short-distance amplitude determined by the Hamiltonian describing b → dγ is combined with a typical long-distance contribution B 0 → D + D − → ρ 0 γ. The latter possesses a significant dynamical phase which induces a CP-violating asymmetry A CP , as well as an important modification of the Stokes vector of the photon.

We present a new method for the prediction of the equilibrium properties of dense gases containing hydrogen isotopes. The proposed approach combines the Feynman-Hibbs effective potential method and a deconvolution scheme introduced by Weeks et al. The resulting equations of state and the chemical potentials as functions of pressure for each of the hydrogen isotope gases depend on a single set o...

In this paper, quantum mechanical effects on nanoscale MOSFET devices are investigated through compact physical models. These models cover quantum mechanical influences on device parameters including long-channel threshold voltage shift, gate capacitance degradation, deteriorated short channel effects and sub-threshold slope. In-depth understanding of device characteristic modification brought ...

III-V growth and surface conditions strongly influence the physical structure and resulting optical properties of self-assembled quantum dots (QDs). Beyond the design of a desired active optical wavelength, the polarization response of QDs is of particular interest for optical communications and quantum information science. Previous theoretical studies based on a pure InAs QD model failed to r...

While structures and reactivities of many small molecules can be computed efficiently and accurately using quantum chemical methods, heuristic approaches remain essential for modeling complex structures and large-scale chemical systems. Here, we present a heuristics-aided quantum chemical methodology applicable to complex chemical reaction networks such as those arising in cell metabolism and p...

conclusions all treatment modalities showed a significant analgesic effect on cnbp in rats, being most prominent with the quantum light therapy. results analgesic effects were observed with all treatment regimens; however, the most prominent median analgesic effect was shown in the quantum light therapy in combination with acupuncture for estrogen-induced cnbp (pf1 = 663.9, pf2 = 403.4) (p = 0....

It is well-documented that certain oxides (such as Re2O7, B2O3, MoO3, V2O5, etc.) can provide friction coefficients of 0.1-0.3 to sliding surfaces at elevated temperatures and thus they are often referred to as lubricious oxides in the tribology literature. In a recently proposed crystal chemical model, Erdemir was able to establish a close correlation between the reported friction coefficients...

We propose an all-order perturbative expression for the dressing phase of the AdS5 × S string S-matrix at strong coupling. Moreover, we are able to sum up large parts of this expression. This allows us to start the investigation of the analytic structure of the phase at finite coupling revealing a few surprising features. The phase obeys all known constraints including the crossing relation and...

Beisert et al. have identified an integrable SU(2, 2) quantum spin chain which gives the one-loop anomalous dimensions of certain operators in large Nc QCD. We derive a set of nonlinear integral equations (NLIEs) for this model, and compute the scattering matrix of the various (in particular, magnon) excitations. 1 Department of Physics, Ewha Womans University, Seoul 120-750, South Korea 2 Phys...

Potential immunological activities of three compounds: RM54 and its two derivatives RM55 and RM56, were evaluated in several, selected in vitro and in vivo tests such as: mitogen-induced lymphocyte proliferation, cytokine production, the humoral immune response in vitro and carrageenan test. Leflunomide served as a reference drug. The studied compounds showed differential, generally immunosuppr...
