While CKM angles often exhibit clean relationships with standard model observables, the sides of the unitarity triangle often require lattice computations in order to extract fundamental Standard Model parameters from experimental data. I will cover some of the most recent advances in flavor physics, in particular in the b and c sectors. While the former sees lattice QCD as one of the most impo...

x-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of fe-10ni-7mn (wt. %) maraging steel. integral peak breadths were analyzed using classical williamson-hall equation taking the elastic anisotropy into account. it was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...

Mixed crystals of alkali halides find applications in optical, optoelectronics and electronic devices. In the present study the pure and mixed crystals of NaClx NaBry-x KCl1-y were grown from the aqueous solution. The grown crystals were characterized by taking XRD, TG/DTA and Vicker’s hardness measurement. The Debye temperature is an important parameter of a solid. Several methods of evaluatin...

In the study of Weyl-Heisenberg frames the assumption of having a finite frame upper bound appears recurrently. In this note it is shown that it actually depends critically on the timefrequency lattice used. Indeed, for any irrational > 0 we can construct a smooth g 2 L2(R) such that for any two rationals a > 0 and b > 0 the collection (gna;mb)n;m2Zof time-frequency translates of g has a finite...

The capsids of large, icosahedral dsDNA viruses are built from well-ordered aggregates of capsomers, known as trisymmetrons and pentasymmetrons, which are centered on the icosahedral 3-fold and 5-fold axes, respectively. We derive the complete set of rules for constructing an icosahedral structure from these symmetrons when the T lattice symmetry is odd and show that there are three classes of ...

in this paper we give an elementary argument about the atoms and coatoms of the latticeof all subgroups of a group. it is proved that an abelian group of finite exponent is strongly coatomic.

High-resolution TEM is well-suited to characterizing nanocrystals, where lattice fringes serve as a source of structural information [1, 2]. For example, 3D lattice parameters can be measured from 2D lattice fringe images taken at as few as two different specimen orientations [3-6]. Recent work has shown that lattice fringe-visibility maps, a thin-specimen extension of bend-contour and channeli...
