Signal Transduction Mechanisms for Stem Cell Differentation Into Cardiomyocytes
(2009-08-05)Cardiovascular diseases are among the leading causes of death worldwide and particularly in the developed World. The search for new therapeutic approaches for improving the functions of the damaged heart is therefore a ... -
Signals embedded in the radial velocity noise
(EDP Sciences, 2013-04-25)Bayesian data analysis techniques, together with suitable statistical models, can be used to obtain much more information from noisy data than the traditional frequentist methods. For instance, when searching for periodic ... -
Signals embedded in the radial velocity noise: Periodic variations in the tau Ceti velocities
(2013-03)Context. The abilities of radial velocity exoplanet surveys to detect the lowest-mass extra-solar planets are currently limited by a combination of instrument precision, lack of data, and “jitter”. Jitter is a general term ... -
Signatures from a merging galaxy cluster and its AGN population : LOFAR observations of Abell 1682
(2019-07-05)We present LOFAR data from 110-180 MHz of the merging galaxy cluster Abell 1682, alongside archival optical, radio, and X-ray data. Our images of 6 arcsec in resolution at low frequencies reveal new structures associated ... -

The significant contribution of minor mergers to the cosmic star formation budget
(2013-12)We estimate an empirical lower limit for the fraction of cosmic star formation that is triggered by minor mergers in the local Universe. Splitting the star formation budget by galaxy morphology, we find that early-type ... -
Signs of Dystopia and Demoralization in global academia: Reflections on the precarious and destructive effects of the colonization of the Lebenswelt
(2017-05-02)Purpose Our paper has been written in the style of a provocative essay. It starts with the observation that neo-liberalism has become the leading “policy doctrine” in Higher Education (HE) systems across the globe. This ... -
Signs of telling: narrative voice and the interactive
(2004)In terms of sign systems and the way they are--used, the experience of the interactive resembles nothing else so much as it resembles the experience of narrative. Narrative is best understood as a relationship between a ... -
Sihlhallenstrasse Neunzehn : Zürich, Switzerland
(2009-04)Group exhibition curated by Bettina Muerner and Sebastian Utzni bringing together a group of conceptual artists. Artists exhibiting included: Helsinki based English artist Duncan Butt Juvonen, the text-based works of Gerald ... -
'Silence bleeds': Hamlet across borders : The Shakespearean Adaptations of Sulayman Al-Bassam
(2008)This article addresses the writing and performance work of Anglo-Kuwaiti director Sulayman Al-Bassam, tracing the development of his various adaptations of Shakespeare's Hamlet into English and Arabic 'cross-cultural' ... -
Silencing and Freedom of Speech in UK Higher Education
(2021-06-01)Freedom of speech in universities is currently an issue of widespread concern and debate. Recent empirical findings in the UK shed some light on whether speech is unduly restricted in the university, but it suffers from ... -
Silencing of Essential Genes within a Highly Coordinated Operon in Escherichia coli
(2015-08-15)Essential bacterial genes located within operons are particularly challenging to study independently because of coordinated gene expression and the nonviability of knockout mutants. Essentiality scores for many operon genes ... -
Silent Landscapes, Textured Memory : Keith Morris Washington's Lynching Paintings
(2017-06-01)Keith Morris Washington’s landscape paintings have received surprisingly little scholarly attention, and thus the present article aims to address that lack. Primarily, this article argues that in representing landscapes ... -
Silicate evolution in brown dwarf disks
(2009-08-10)We present a compositional analysis of the 10 mu m silicate spectra for brown dwarf disks in the Taurus and Upper Scorpius (UppSco) star-forming regions, using archival Spitzer/Infrared Spectrograph observations. A variety ... -
Silicon builds resilience in strawberry plants against both strawberry powdery mildew Podosphaera aphanis and two-spotted spider mites Tetranychus urticae
(2020-12-08)Silicon is found in all plants and the accumulation of silicon can improve plant tolerance to biotic stress. Strawberry powdery mildew (Podosphaera aphanis) and two-spotted spider mite (Tetranychus urticae) are both ... -
Silicon carbide grains of type C provide evidence for the production of the unstable isotope Si in supernovae
(2013-07-01)Carbon-rich grains are observed to condense in the ejecta of recent core-collapse supernovae (SNe) within a year after the explosion. Silicon carbide grains of type X are C-rich grains with isotopic signatures of explosive ... -
Silicon enhances the constitutive defence pathway in strawberries against strawberry powdery mildew and two-spotted spider mites
(2019-11-21)Strawberry powdery mildew (Podosphaera aphanis) is a major fungal disease affecting strawberry production. The work reported here assessed the use of silicon as a nutrient (Sirius) delivered via the fertigation system in ...
