Characterizing precursors to stellar clusters with Herschel
(2011-11-01)Context. Despite their profound effect on the universe, the formation of massive stars and stellar clusters remains elusive. Recent advances in observing facilities and computing power have brought us closer to understanding ... -
Characterizing the disk around the TW Hydrae Association brown dwarf 2MASSW J1207334-393254
(2007-05-20)We present detailed modeling of the disk around the TW Hydrae Association (TWA) brown dwarf 2MASSW J1207334 - 393254 (2M1207), using Spitzer observations from 3.6 to 24 mu m. The spectral energy distribution (SED) does not ... -
Characterizing the Vibration Responses of Flexible Workpieces during the Turning Process for Quality Control
(2023-11-23)Featured Application: This study represents a breakthrough in the engineering of turning processes for manufacturing. By examining dynamic properties and vibration response during turning, it provides key insights for ... -
Charged-particle and neutron-capture processes in the high-entropy wind of core-collapse supernovae
(2010-04-01)The astrophysical site of the r-process is still uncertain, and a full exploration of the systematics of this process in terms of its dependence on nuclear properties from stability to the neutron drip-line within realistic ... -
Charity and Poverty in England, c.1680-1820 : Wild and Visionary Schemes
(Manchester University Press, 2009-11-30)This book explores responses to poverty in eighteenth-century England, with an eye to some of the odder manifestations of charity and poor relief. Whether discussing proposals for vast inland colonies or cosy firesides, ... -

Charmers and Charming in England and Wales from the Eighteenth to the Twentieth Century
(1998-01)Charmers have long been recognised as an important aspect of folk medicine. Unfortunately, however, they have usually been conflated with cunning-folk and consequently the welldefined tradition of charming has been rather ... -
Chartist Studies and Malcolm Chase: a Re-appreciation
(2023-11-17)Malcolm Chase (1957–2020) was the pre-eminent scholar of the Chartist democratic movement, and more broadly, of working-class political and social action in early nineteenth-century Britain. His work in many respects shaped ... -
Chasing discs around O-type (proto)stars : Evidence from ALMA observations
(2017-06-13)Context. Circumstellar discs around massive stars could mediate the accretion onto the star from the infalling envelope, and could minimize the effects of radiation pressure. Despite such a crucial role, only a few convincing ... -
Chasing the identification of ASCA Galactic Objects (ChIcAGO): An X-ray survey of unidentified sources in the galactic plane. I : Source sample and initial results
(2014-05)We present the Chasing the Identification of ASCA Galactic Objects (ChIcAGO) survey, which is designed to identify the unknown X-ray sources discovered during the ASCA Galactic Plane Survey (AGPS). Little is known about ... -
Cheap Newton steps for optimal control problems: automatic differentiation and Pantoja's algorithm
(1999)In this paper we discuss Pantoja's construction of the Newton direction for discrete time optimal control problems. We show that automatic differentiation (AD) techniques can be used to calculate the Newton direction ... -
Checking chess checks with chunks: A model of simple check detection
(Cognitive Science Society, 2009)The procedure by which humans identify checks in check positions is not well understood. We report here our experience in modelling this process with CHREST, a general-purpose cognitive model that has previously successfully ... -
Chemical aspects related to using recycled geopolymers as aggregates
(2018-09-01)Despite extensive research into sustainability of geopolymers, end-of-life aspects have been largely overlooked. A recycling scenario is examined in this study. This requires an investigation of alkali leaching potential ... -
The chemical composition of TS 01, the most oxygen-deficient planetary nebula AGB nucleosynthesis in a metal-poor binary star
(2010)The planetary nebula TS 01 (also called PN G 135.9+55.9 or SBS 1150+599A) with its record-holding low oxygen abundance and its double degenerate close binary core (period 3.9 h) is an exceptional object located in the ...
