Continuous wave terahertz radiation from an InAs/GaAs quantum-dot photomixer device
(2012-08-20) - Journal articleGeneration of continuous wave radiation at terahertz (THz) frequencies from a heterodyne source based on quantum-dot (QD) semiconductor materials is reported. The source comprises an active region characterised by multiple ... -
Continuously tuneable critical current in superconductor-ferromagnet multilayers
(2017-06-27) - Journal articleWe demonstrate that the critical current of superconducting Nb/Ni multilayers can be continuously tuned by up to a factor of three during magnetization reversal of the Ni films under an applied in-plane magnetic field. Our ... -
The contour-advective semi-Lagrangian hybrid algorithm approach to weather forecasting and freely propagating inertia-gravity waves in the shallow-water system
(University of St Andrews, 2009-06-24) - ThesisThis thesis is aimed at extending the spherical barotropic contour-advective semi-Lagrangian (CASL) Algorithm, written in 1996 by David Dritschel and Maarten Ambaum, to more complex test cases within the shallow-water ... -
Contra-directional coupling into slotted photonic crystals for spectrometric applications
(2014-08-01) - Journal articleWe propose and demonstrate the concept of a contra-directional coupler between a W1 and a slotted photonic crystal waveguide. The bandwidth and operating wavelength of such a coupler can be controlled via its geometrical ... -
Contracting institutions and development
(2012) - Journal articleThe quality of contracting institutions has been thought to be of second-order importance next to the impact that good property rights institutions can have on long- run growth. Using a large range of proxies for each type ... -
Contracts and cooperation : the relative failure of the Irish dairy industry in the late nineteenth century reconsidered
(2015) - Journal articleWhy did the establishment of cooperative creameries in late nineteenth century Ireland fail to halt the relative decline of her dairy industry compared to other emerging producers? This paper compares the Irish experience ... -
Contrasting changes in the abundance and diversity of North American bird assemblages from 1971 to 2010
(2016-12) - Journal articleAlthough it is generally recognized that global biodiversity is declining, few studies have examined long-term changes in multiple biodiversity dimensions simultaneously. In this study we quantified and compared temporal ... -
Contrasting migratory responses of two closely-related seabirds to long-term climate change
(2016-11-09) - Journal articleMany marine predators migrate between breeding and non-breeding areas to target resources that are seasonal but spatio-temporally predictable, and so are vulnerable to climate-induced changes in prey phenology and abundance. ... -
Contrastive reasons and promotion
(2014-10) - Journal articleA promising but underexplored view about normative reasons is contrastivism, which holds that considerations are fundamentally reasons for things only relative to sets of alternatives. Contrastivism gains an advantage by ... -
Contrastivism about reasons and ought
(2015-06-04) - Journal articleContrastivism about some concept says that the concept is relativized to sets of alternatives. Relative to some alternatives, the concept may apply, but relative to others, it may not. This article explores contrastivism ... -
Contribution of mode-coupling and phase-mixing of Alfvén waves to coronal heating
(2017-05-12) - Journal articleContext. Phase-mixing of Alfvén waves in the solar corona has been identified as one possible candidate to explain coronal heating. While this scenario is supported by observations of ubiquitous oscillations in the corona ... -
The contribution of the subthalamic nucleus to executive functions in rat
(University of St Andrews, 2014-12-01) - ThesisLesions of the subthalamic nucleus (STN) alleviate the cardinal signs of idiopathic as well as MPTP-induced Parkinson’s disease in primates. For this reason, the STN is a target for clinical treatment of Parkinson’s ... -
Contribution to the Public Health Consultation : 'Choosing Health?'
(Sustainable Development Commission, 2004-05-01) - ReportThe Sustainable Development Commission’s submission to the Department of Health's 'Choosing Health?' consultation. -
Control and measurement of ultrafast pulses for pump/probe-based metrology
(University of St Andrews, 2007) - ThesisIn this thesis the control of ultrafast (10⁻¹³ s) optical pulses used for metrological applications has been investigated. Two different measurement set-ups have been considered, both based around the `pump-probe' technique, ... -
Control control control : a reassessment and comparison of GenBank and chromatogram mtDNA sequence variation in Baltic grey seals (Halichoerus grypus)
(2013-08-16) - Journal articleGenetic data can provide a powerful tool for those interested in the biology, management and conservation of wildlife, but also lead to erroneous conclusions if appropriate controls are not taken at all steps of the ... -
Control of a two-dimensional electron gas on SrTiO3 (111) by atomic oxygen
(2014-10-20) - Journal articleWe report on the formation of a two-dimensional electron gas (2DEG) at the bare surface of (111) oriented SrTiO3. Angle resolved photoemission experiments reveal highly itinerant carriers with a sixfold symmetric Fermi ... -
The control of infectious diseases in Fife, c. 1855-1950
(University of St Andrews, 1989) - ThesisThis thesis is a study-of the contribution of public health administration to the control of Infectious diseases in Fife during the period c. 1855-1950. It is a local study in the social history of medicine which attempts ... -
The control of mitochondrial morphology and dynamics in Arabidopis thaliana
(University of St Andrews, 2006) - ThesisMitochondria are ubiquitous eukaryotic organelles which carry out a range of essential functions, most notably the production of ATP through the process of oxidative phosphorylation. While the main biochemical function ... -
