Superconducting RF Cryomodule Demagnetization

This note presents measurements that support the proposition that it is feasible to demagnetize a fully assembled superconducting RF cryomodule

Optical integral field spectroscopy of the extended line emission around six radio-loud quasars

We present integral field spectroscopy of a small sample of radio-loud quasars at intermediate redshift (0.26<z<0.60), most of which are associated with large radio sources. All have oxygen line emission extended over tens of kiloparcsecs, and these nebulae display a diverse range in both morphology and kinematic behaviour. Two quasars show 'plumes' of extended line emission, two show a clumpy structure and a further one shows a smooth distribution. There is no clear pattern with regard to the distribution of the ionized gas in relation to the radio source axis; the extended emission-line regions are found both parallel and perpendicular - and also totally unrelated to - the radio axis. The velocity structure of the ionized gas ranges from essentially static to apparent smooth rotation, and in two cases, show a clear association with the radio source. Given the disparity in properties, the nebulae all show a surprisingly similar ionization state, as measured by the extended lines of [OII] and [OIII]. Assuming the gas is ionized by at least the nearby quasar nucleus, we use the emission line ratios to infer a pressure in the ionized gas; in all cases we find it to be at high pressure, suggesting confinement by an external (probably intracluster) medium.Comment: 14 pages, 18 figures, 10 of which are presented separately; accepted for publication in MNRA

United States budgetary costs of Post-9/11 wars through FY2018

Originally published on the Watson Institute's Costs of War Project website: http://watson.brown.edu/costsofwar/papers/2017/USBudgetaryCostsFY2018The costs to the United States of post-9/11 wars will total more than $5.6 trillion by the end of fiscal year 2018, a new Costs of War report finds, and the average American taxpayer has spent$23,386 on these wars since 2001. “The U.S. wars in Iraq, Syria, Afghanistan and Pakistan, and the increased spending on homeland security and the departments of defense, state and veterans affairs since the 9/11 attacks have cost more than $4.3 trillion in current dollars through fiscal year 2017,” said Neta Crawford, Costs of War co-director and a professor of political science at Boston University. “Adding likely costs for fiscal year 2018 and estimated future obligations for veterans’ care, the costs of war total more than$5.6 trillion.

The lone parent pilots after 12 to 24 months: an impact assessment of in-work credit, work search premium, extended schools childcare, quarterly work focused interviews and new deal plus for lone parents

From April 2004, a set of Government policies designed to help lone parents into work have been piloted in various combinations in a number of Jobcentre Plus districts in Great Britain. The five policies are: In Work Credit (IWC), Work Search Premium (WSP), Extended Schools Childcare (ESC) and Childcare Tasters, Quarterly Work Focused Interviews (QWFIs) for lone parents whose youngest child is aged 12 or over in Local Education Authorities (LEAs) in which an ESC pilot is operating (ESQWFI), and New Deal Plus for Lone Parents (ND+fLP), hereafter collectively referred to as 'the lone parent pilots' (LPPs or 'the pilots'). The pilots were rolled out in four Phases, the first three of which are analysed in this report. This report estimates the impact of the LPPs on lone parents who have received Income Support (IS) or Jobseeker's Allowance (JSA) for at least 12 months. It uses a difference-in-differences (DiD) estimator, and makes use of lone parents in districts not operating a pilot as a comparison group. The data covers the first 12 months (Phase 3 districts) to the first 24 months (Phase 1 districts) of the pilots' operation, and so should be seen as giving the early impacts. Impacts were estimated separately for the stock of lone parents who had been on benefit for at least 12 months when the pilots began, and the flow sample of lone parents whose claim of IS/JSA reached 12 months after the pilots began
