We present a leading order (LO) estimate for the longitidinal-transverse spin asymmetry (ALT ) in the nucleon-nucleon polarized Drell-Yan process at RHIC and HERA~ N energies in comparison with ALL and ATT . ALT receives contribution from g1, the transversity distribution h1, and the twist-3 distributions gT and hL. For the twist-3 contribution we use the bag model prediction evolved to a high ...

Abstract Funding Acknowledgements Type of funding sources: None. Background In advanced stages dilated cardiomyopathy (DCM), both atrial function and left ventricle (LV) myocardial mechanics are blunted. Left reservoir strain (LASr) is a sensitive parameter for (LA) evaluation. Our study aimed to find correlation between LASr depression rotational parameters damage in patients with DCM, using 4...

Based on the light-cone (LC) framework and the kT factorization formalism, the transverse momentum effects and the different helicity components’ contributions to the pion form factor Fπ(Q) are recalculated. In particular, the contribution to the pion form factor from the higher helicity components (λ1 + λ2 = ±1), which come from the spinspace Wigner rotation, are analyzed in the soft and hard ...

We study two semiclassical limits of $SU(2)$ Yang-Mills theory on a spatial torus with 't Hooft twist: the ``femtouniverse,'' where all $\mathbb{T}^3$ directions are small, and deformed $\mathbb{T}^2 \times \mathbb{S}^1$, small $\mathbb{S}^1$ large or infinite $\mathbb{T}^2$. Carefully defining symmetries, we show that classical ground states, while different, have same transformation propertie...

In this paper a method is presented for torsional analysis of non-homogeneous tubes with arbitrarily shaped cross-sections. A previously presented method based on Bredt’s theory is extended to achieve formulas for torsional analysis. Shear modulus varies through the thickness according to a power law distribution. To validate the accuracy of the presented formulas for angle of twist and shear s...

cold roll-forming is a process in which the roll of sheet is formed by passing continuously through the set of rotary rollers without changing thickness in a cool way until it is formed to the desired profile. in this paper a parametric study on the section twist angle in roll-forming the non-symmetric channel is presented, using finite element simulation. at first finite element simulation res...
