CAL : a language for aggregating functional and extrafunctional constraints in streaming networks
(University of Hertfordshire, 2011)In this article we present the Constraint Aggregation Language (CAL), a declarative language for describing properties of stateless program components that interact by exchanging messages. CAL allows one to describe ... -
The Calais Winds took our plans away: Art therapy as shelter
(2018-08-01)This article examines the role of construction materials, story and group as alternative forms of shelter and crisis relief for refugees in transit in Calais, northern France. It draws on examples from an ongoing art therapy ... -
Calcium influx stimulated by activation of ATP receptors on sensory neurons from rat dorsal root ganglia
(1991)A combination of microspectrofluorimetry and single cell voltage-clamp was used to examine the response to ATP of cultured neurons from rat dorsal root ganglia. ATP activated an inward current and a rise in internal calcium ... -
Calcium nitrate as a remedy for salt-stressed cucumber plants
(2002)The effect of calcium nitrate [Ca(NO)] on growth and yield of cucumber (Cucumis sativus L. cv. Beit Alpha F1) plants grown in containers under high root-zone salinity was investigated. Treatments were: 1) control (C): soil ... -
Calcium- and myosin-dependent changes in troponin structure during activation of heart muscle
(2009)Each heartbeat is triggered by a pulse of intracellular calcium ions which bind to troponin on the actin-containing thin filaments of heart muscle cells, initiating a change in filament structure that allows myosin to bind ... -
Calculated densities of H3O+(H2O)n,NO2− (H2O)n, CO3− (H2O)n and electron in the nighttime ionosphere of Mars : Impact of solar wind electron and galactic cosmic rays
(2007-12-01)We have calculated the densities of positive ions and negative ions in the ionosphere of Mars at solar zenith angle 106° between height interval 0 km and 220 km. This model couples ion-neutral, electron neutral, dissociation ... -
Calculating WCET Estimates from Timed Traces
(2015-09-01)Real-time systems engineers face a daunting duty: They must ensure that each task in their system can always meet its deadline. To analyse schedulability they must know the worst-case execution time (WCET) of each task. ... -
Calculation of critical speed from raw training data in recreational marathon runners
(2020-12-01)INTRODUCTION: Critical speed (CS) represents the highest intensity at which a physiological steady state may be reached. The aim of this study was to evaluate whether estimations of CS obtained from raw training data can ... -
Calculation of the Astrophysical S-Factor and Reaction-Rate for L-8(ALPHA,N0)B-11

Calculation of the He-3(He-3, 2p)He-4 AND H-3(H-3, 2N)He-4 astrophysical S-factor at low energies
(1992-08)We have calculated the cross sections for the charge symmetric reactions He-3(He-3,2p)He-4 and He-3(He-3,2p)He-4 at sub-Coulomb energies in the potential model. Good agreement with the experimental data is obtained. The ... -
Calculations of fission rates for r-process nucleosynthesis
(2005-01-24)Fission plays an important role in the r-process which is responsible; not only for the yields of transuranium isotopes, but may have a strong influence on the formation of the majority of heavy nuclei due to fission ... -
Calculations of nuclear reactions of astrophysical interest involving unstable nuclei

Calculations of Periodicity From H Alpha Profiles of Proxima Centauri
(2017-01-25)In this report the stellar rotation signal for Proxima Centauri is investigated. High-resolution spectra taken with UVES and HARPS of Proxima Centauri over a 13-year period is used as well as photometric observations of ... -
Calculations of periodicity from Halpha profiles of Proxima Centauri
(2017-06-07)We investigate retrieval of the stellar rotation signal for Proxima Centauri. We make use of high-resolution spectra taken with UVES and HARPS of Proxima Centauri over a 13-yr period as well as photometric observations of ... -
Calibrated and completeness-corrected optical stellar density maps of the Northern Galactic Plane
(2016-03-21)Following on from the second release of calibrated photometry from IPHAS, the INT/WFC Photometric Hα Survey of the Northern Galactic Plane, we present incompleteness-corrected stellar density maps in the r and i photometric ... -

Calibrating the relation of low-frequency radio continuum to star formation rate at 1 kpc scale with LOFAR
(2018-10-15)Radio continuum (RC) emission in galaxies allows us to measure star formation rates (SFRs) unaffected by extinction due to dust, of which the low-frequency part is uncontaminated from thermal (free-free) emission. We ...
