Understanding the spin-down rate changes of PSR B0919+06

Spin - down of Relativistic Stars with Phase Transitions and PSR

Comparing models of the periodic variations in spin-down and beamwidth for PSR B1828−11

We build a framework using tools from Bayesian data analysis to evaluate models explaining the periodic variations in spin-down and beamwidth of PSR B1828−11. The available data consist of the time-averaged spin-down rate, which displays a distinctive double-peaked modulation, and measurements of the beamwidth. Two concepts exist in the literature that are capable of explaining these variations...

Spin - down of Relativistic Stars with Phase Transitions and PSR J 0537 - 6910

An abstract should be given Using a highly accurate numerical code, we study the spin down of rotating relativistic stars, undergoing a quark decon-finement phase transition. Such phase transitions have been suggested to yield an observable signal in the braking index of spinning-down pulsars, which is based on a " backbending " behaviour of the moment of inertia. We focus on a particular equat...

the impact of explicit instruction of top-down reading strategies on reading comprehension of intermediate efl learners

this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
