Leading logarithmic QCD corrections to the B_s --> \gamma \gamma decays in the two Higgs doublet model [PDF]

, 1997
We calculate the leading logarithmic QCD corrections to the decay B_s --> \gamma \gamma in the two Higgs doublet model (2HDM) including O_7 type long distance effects and estimate the restrictions of the 2HDM parameters, tan\beta and m_H, using the ...

The Scale Effect Study on the Transient Fluid–Structure Coupling Performance of Composite Propellers

Journal of Marine Science and Engineering, 2022
In order to predict the fluid–structure coupling performance of a full-scale composite propeller under a wake flow field behind a full ship, a bidirectional transient fluid–structure coupling algorithm was established.

Weak Scale Superstrings [PDF]

, 1996
Recent developments in string duality suggest that the string scale may not be irrevocably tied to the Planck scale. Two explicit but unrealistic examples are described where the ratio of the string scale to the Planck scale is arbitrarily small ...

Conformal Symmetry as a Template: Commensurate Scale Relations and Physics Renormalization Schemes [PDF]

, 1999
Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the "generalized Crewther relation", which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum ...

Optimization of Nanowires Ratio in Nano-scale SiNWT Based SRAM Cell

MATEC Web of Conferences, 2015
This paper represents the impact of nanowires ratio of silicon nanowire transistors on the characteristics of 6-transistors SRAM cell. This study is the first to demonstrate nanowires ratio optimization of Nano-scale SiNWT Based SRAM Cell.

A ratio scale for social distance

Journal of the Experimental Analysis of Behavior, 2020
Choosing a larger–later reward over a smaller–sooner reward may be thought of as altruism toward one's future self. A question that arises in this connection is: What is the relation between delay and social discounting? To begin to answer this question, social and delay discount functions need to be comparable.

NLL Corrections for B-Meson Radiative Exclusive Decays [PDF]

, 1999
We calculate the next-to-leading corrections to the branching ratio of exclusive $B\to K^* \gamma$ decay. The renormalization scale dependence is reduced compared to the leading logarithmic result but there remains a dependence on a cutoff parameter of ...

Resolving Scale Ambiguity Via XSlit Aspect Ratio Analysis

, 2015
In perspective cameras, images of a frontal-parallel 3D object preserve its aspect ratio invariant to its depth. Such an invariance is useful in photography but is unique to perspective projection.

Unraveling unparticles through violation of atomic parity and rare beauty [PDF]

, 2007
We put constraints on unparticle physics, specifically on the scale $\Lambda_\U$ and the scale dimension $d_\U$ of unparticle operators, using (i) measurements of atomic parity violation as well as (ii) branching ratio and CP asymmetry measurements in ...
