The damping characteristics of Ti50Ni50-xCux (x = 0~30 at.%) shape memory alloys (SMAs) at a low frequency have been studied using a dynamic mechanical analyzer. The magnitude of the tan δ value and the values of the storage modulus (E₀) softening/hardening and the strain variation exhibited in B2↔B19 transformation are all higher than those in B2↔B19' transformation. The larger E₀ softening/ha...

The decay B → Kπ, dominated by a b → s penguin amplitude, holds the potential for exhibiting new physics in this amplitude. In the pure QCD penguin limit one expects CKπ = 0 and SKπ = sin 2β for the coefficients of cos∆mt and sin∆mt in the time-dependent CP asymmetry. Small nonpenguin contributions lead to corrections to these expressions which are calculated in terms of isospin-related B → Kπ ...

Despite progress in understanding chromatin function, the structure of the 30 nm chromatin fiber has remained elusive. However, with the recent crystal structure of a short tetranucleosomal array, the 30 nm fiber is beginning to come into view.

We discuss simple integration methods for the calculation of rotating black hole scattering resonances both in the complex frequency plane (quasinormal modes) and the complex angular momentum plane (Regge poles). Our numerical schemes are based on variations of “phase-amplitude” methods. In particular, we discuss the Prüfer transformation, where the original (frequency domain) Teukolsky wave eq...

We introduce a new wide class of p–adic pseudodifferential operators. We show that the basis of p–adic wavelets is the basis of eigenvectors for the introduced operators.

Non-linear special relativity (or doubly special relativity) is a simple framework for encoding properties of flat quantum space-time. In this paper we show how this formalism may be generalized to incorporate curvature (leading to what might be called “doubly general relativity”). We first propose a dual to non-linear realizations of relativity in momentum space, and show that for such a dual ...
