Electron–phonon processes of the silicon-vacancy centre in diamond
(IOP Publishing, 2015)We investigate phonon induced electronic dynamics in the ground and excited states of the negatively charged silicon-vacancy (SiV−) centre in diamond. Optical transition line widths, transition wavelength and excited state ... -
Electrophilic activity-based RNA probes reveal a self-alkylating RNA for RNA labeling
(2014)Probes that form covalent bonds with RNA molecules based on their chemical reactivity would advance our ability to study the transcriptome. We developed a set of electrophilic activity-based RNA probes designed to react ... -
An electrophysiological assessment of distractor suppression in visual search tasks
(Wiley-Blackwell, 2009)We investigated whether the N2pc is unequivocally linked to distractor-suppression mechanisms, as is commonly assumed. According to the distractor-suppression account of the N2pc, no suppression, and thus no N2pc, should ... -
Electrophysiological Correlates of Spatial Orienting Towards Angry Faces: A Source Localization Study
(Pergamon Press, 2008)The goal of this study was to examine behavioral and electrophysiological correlates of involuntary orienting toward rapidly presented angry faces in non-anxious, healthy adults using a dot-probe task in conjunction with ... -
Electrophysiological Correlates of the Autobiographical Implicit Association Test (aIAT): Response Conflict and Conflict Resolution
(Frontiers Media S.A., 2016)The autobiographical IAT (aIAT) is an implicit behavioral instrument that can detect autobiographical memories encoded in an individual's mind by measuring how quickly this person can categorize and associate sentences ... -
Electrophysiological Dissociation of Picture Versus Word Encoding: The Distinctiveness Heuristic as a Retrieval Orientation
(Massachusetts Institute of Technology Press, 2005)Event-related potentials (ERPs) were used to investigate the neural processes underlying the distinctiveness heuristic— a response mode in which participants expect to remember vivid details of an experience and make ... -
Electrophysiological Evidence of Attentional Biases in Social Anxiety Disorder
(Cambridge University Press, 2009)Background: Previous studies investigating attentional biases in social anxiety disorder (SAD) have yielded mixed results. Recent event-related potential (ERP) studies using the dot-probe paradigm in non-anxious participants ... -
Electrostatic Interactions between Elongated Monomers Drive Filamentation of Drosophila Shrub, a Metazoan ESCRT-III Protein
(2016)SUMMARY The endosomal sorting complex required for transport (ESCRT) is a conserved protein complex that facilitates budding and fission of membranes. It executes a key step in many cellular events, including cytokinesis ... -
Electrostatic Localization of RNA to Protocell Membranes by Cationic Hydrophobic Peptides
(WILEY-VCH Verlag, 2015)Cooperative interactions between RNA and vesicle membranes on the prebiotic earth may have led to the emergence of primitive cells. The membrane surface offers a potential platform for the catalysis of reactions involving ... -
Electrostatic solitary waves in an electron-positron pair plasma with suprathermal electrons
(AIP Publishing, 2017)The nonlinear propagation of electrostatic solitary waves is studied in a collisionless electron-positron pair plasma consisting of adiabatic cool electrons, mobile cool positrons (or electron holes), hot suprathermal ... -
Electrostatically Doped Silicon Nanowire Arrays for Multispectral Photodetectors
(American Chemical Society (ACS), 2019-10-02)Nanowires have promising applications as photodetectors with superior ability to tune absorption with morphology. Despite their high optical absorption, the quantum efficiencies of these nanowire photodetectors remain low ... -
Electrostriction in elastic dielectrics undergoing large deformation

Electroweak symmetry breaking from dimensional deconstruction
(Elsevier BV, 2001)We propose a new class of four-dimensional theories for natural electroweak symmetry breaking, relying neither on supersymmetry nor on strong dynamics at the TeV scale. The new TeV physics is perturbative, and radiative ... -
The Elemental Composition of Demospongiae from the Red Sea, Gulf of Aqaba
(Public Library of Science, 2014)Trace elements are vital for the growth and development of all organisms. Little is known about the elemental content and trace metal biology of Red Sea demosponges. This study establishes an initial database of sponge ... -
Elemental Mercury Concentrations and Fluxes in the Tropical Atmosphere and Ocean
(American Chemical Society (ACS), 2014)Air–sea exchange of elemental mercury (Hg0) is a critical component of the global biogeochemical Hg cycle. To better understand variability in atmospheric and oceanic Hg0, we collected high-resolution measurements across ... -
Elementary bounds on mixing times for decomposable Markov chains
(Elsevier BV, 2017-09)Many finite-state reversible Markov chains can be naturally decomposed into “projection” and “restriction” chains. In this paper we provide bounds on the total variation mixing times of the original chain in terms of the ... -
An Elementary Theorem in Geometric Invariant Theory
(American Mathematical Society, 1961) -
Elements of string cosmology
(Elsevier, 1992)Aspects of string cosmology for critical and non-critical strings are discussed emphasizing the necessity to account for the dilaton dynamics for a proper incorporation of "large-small" duality. This drastically modifies ... -
The Elephant and the Whale: Empires of Land and Sea
(Informa UK Limited, 2007)The Trustees and Director of the National Maritime Museum have done me a double honour by asking me to deliver the Caird Lecture and to mark the opening of the Museum's new Research Centre for Imperial and Maritime Studies. ... -
Elevated Preattentive Affective Processing in Individuals with Borderline Personality Disorder: A Preliminary fMRI Study
(Frontiers Media S.A., 2015)Background: Emotion dysregulation is central to the clinical conceptualization of borderline personality disorder (BPD), with individuals often displaying instability in mood and intense feelings of negative affect. Although ...
