In this work, a mass-effective temperature-surface gravity relation (MTGR) is developed for main sequence stars in the range of 6400 K < $T_{\rm eff}$ 20000 with log$g$ > 3.44. The MTGR allows simple estimation masses from their effective temperatures and surface gravities. It can be used solar metallicity rescaled any within -1.00 [Fe/H] 0.7. effect alpha-enhanced compositions also considered ...

The Constraint Effective Potential (CEP) allows a determination of the mass and other quantities directly, without relying upon asymptotic correlator decays. We report and discuss the results of some mass calculations in λΦ 4 4 , obtained from CEP and our improved version of CEP (ICEP).

We consider time-dependent nonlinear Schrödinger equations subject to smooth, lattice-periodic potentials plus additional confining potentials, slowly varying on the lattice scale. After an appropriate scaling we study the homogenization limit for vanishing lattice spacing. Assuming well prepared initial data, the resulting effective dynamics is governed by a homogenized nonlinear Schrödinger e...

Using effective Lagrangian arguments, I explore the qualitative behavior expected at finite temperature for two-flavor lattice QCD formulated with Wilson fermions and a twisted mass term. A rather rich phase structure is predicted, exhibiting Aoki’s parity violating phase along with a deconfinement region forming a conical structure in the space of coupling, hopping parameter, and twisted mass ...

We develop the concept of frequency dependent effective mass, M[over ](omega), of jammed granular materials which occupy a rigid cavity to a filling fraction of 48%, the remaining volume being air of normal room condition or controlled humidity. The dominant features of M[over ](omega) provide signatures of the dissipation of acoustic modes, elasticity, and aging effects in the granular medium....
