Effect of heat treatment on structure and magnetic properties of Fe65.5Cr4Mo4Ga4P12C5B5.5 bulk amorphous alloy [PDF]
China Foundry, 2017 This study deals with the Fe65.5Cr4Mo4Ga4P12C5B5.5 ferromagnetic bulk amorphous alloy. XRD analysis showed an amorphous structure of the as-cast sample. The same method revealed that, after annealing at 973 K for τ=10 min, the sample displayed a crystalline structure with crystalline phases formed.

All-Angle Quasi-Self-Collimation Effect in a Rod-Type Silicon Photonic Crystal
IEEE Photonics Journal, 2015 By changing the symmetry of a photonic crystal (PC) with a rectangular lattice to straighten one of the isofrequency contours, the PC shows an all-angle quasi-self-collimation (quasi-SC) effect. To investigate the straightness of the isofrequency contour

LP decoding excess over symmetric channels [PDF]
, 2015 We consider the problem of Linear Programming (LP) decoding of binary linear codes. The LP excess lemma was introduced by the first author, B. Ghazi, and R. Urbanke (IEEE Trans. Inf. Th., 2014) as a technique to trade crossover probability for "LP excess"

A Novel Plasmonic Sensor Based on Metal–Insulator–Metal Waveguide With Side-Coupled Hexagonal Cavity
IEEE Photonics Journal, 2015 We propose a novel and compact plasmonic sensing structure based on a metal-insulator-metal (MIM) waveguide with a side-coupled hexagonal cavity. The sensing structure has been numerically and theoretically investigated using the finite-difference time ...

Variational problems with singular perturbation [PDF]
, 2005 In this paper, we construct the local minimum of a certain variational problem which we take in the form $\mathrm{inf}\int_\Omega\left\{\frac{\epsilon}{2}kg^2|\nabla w|^2+\frac{1}{4\epsilon}f^2g^4(1-w^2)^2\right\}\,\mathrm{d}x$, where $\epsilon$ is a ...
