Quasinormal modes of Unruh's Acoustic Black Hole

We have studied the sound perturbation of Unruh's acoustic geometry and we present an exact expression for the quasinormal modes of this geometry. We are obtain that the quasinormal frequencies are pure-imaginary, that give a purely damped modes.Comment: 5 Page

The Director Duty of Care in Qatar

In this age of globalization, cross-border investment and intense competition for capital, comparative corporate governance is an increasingly important topic. This Article examines and analyzes the duty of care for directors of publicly-traded companies, comparing Qatari law with Delaware law. It finds that Qatari law on the duty of care is deficient in several respects. Under current Qatari law, directors are liable for duty of care violations for “mistaken” business decisions. Neither gross negligence nor something more than mere negligence is required. Moreover, Qatari law makes these duties non-exculpatory. Thus, in comparison with Delaware, Qatari director obligations are riskier to directors in terms of personal liability and may discourage the most qualified people from becoming directors. Qatar would greatly benefit from modifications to its duty of care law. Specifically, Qatar should enact a business judgment rule (“BJR”) which is vital to creating a balanced risk-taking environment. Qatar’s Companies Law should be amended to include the BJR and should articulate the misconduct necessary to rebut the BJR. The threshold of such conduct should be gross negligence or a business decision for which there is no rational basis. Mere mistake or negligence alone should not be sufficient to impose liability. In addition, Qatar should consider allowing shareholders to approve exculpatory clauses which would insulate directors from liability for duty of care violations based upon conduct where there is no bad faith, self-interest or disloyalty. Doing so would encourage companies to hire the most qualified directors and would encourage the prudent risk-taking that is the hallmark of the world’s most successful corporations

Profile morphology and polarization of young pulsars

We present polarization profiles at 1.4 and 3.1 GHz for 14 young pulsars with characteristic ages less than 75 kyr. Careful calibration ensures that the absolute position angle of the linearly polarized radiation at the pulsar is obtained. In combination with previously published data we draw three main conclusions about the pulse profiles of young pulsars. (1) Pulse profiles are simple and consist of either one or two prominent components. (2) The linearly polarized fraction is nearly always in excess of 70 per cent. (3) In profiles with two components the trailing component nearly always dominates, only the trailing component shows circular polarization and the position angle swing is generally flat across the leading component and steep across the trailing component. Based on these results we can make the following generalisations about the emission beams of young pulsars. (1) There is a single, relatively wide cone of emission from near the last open field lines. (2) Core emission is absent or rather weak. (3) The height of the emission is between 1 and 10 per cent of the light cylinder radius.Comment: Accepted for publication in MNRAS. 16 page
