Spin polarized liquid 3He

, 2008
We have employed the constrained variational method to study the influence of spin polarization on the ground state properties of liquid $^3{\rm He}$. The spin polarized phase, we have found, has stronger correlation with respect to the unpolarized phase.

Polarization and light curve variability: the "patchy shell" model

, 2003
Recent advances in early detection and detailed monitoring of GRB afterglows have revealed variability in some afterglow light curves. One of the leading models for this behavior is the patchy shell model.

Cathodic Protection of X100 Pipeline Steel in Simulated Soil Solution

International Journal of Electrochemical Science, 2018
Generally, the basic parameters of conventional cathodic protection design mostly rely on theoretical or empirical approximate formulas. An over protection phenomenon has emerged for pipeline systems with large scale differences in soil environment. This

Polars of Artin-Schreier curves [PDF]

Acta Arithmetica, 1996
For Artin-Schreier curves \(C\) of genus \(g\) given by an affine equation \(C:y^q+ay=\varphi(x)\) over a finite field \(\mathbb{F}_{q^k}\) the number of points on \(C(\mathbb{F}_{q^k})\) is bounded by the Weil bound \(q^k+1+ 2gq^{k/2}\) and by the trivial bound \(q^{k+1}+1\). The authors can improve these two bounds in certain cases. The method relies
