Spectroscopy-based modelling of the 3D structure of the β subunit of the high affinity IgE receptor
(2000)The high affinity IgE receptor, possesses a tetrameric structure. The 243 residue β subunit is a polytopic protein with four hydrophobic membrane-spanning segments, whereas the individual α and γ subunits are bitopic ... -
Spectrum Sensing of DVB-T2 Signals in Multipath Channels for Cognitive Radio Networks
(VDE VERLAG GMBH, 2018-06-14)In this paper, spectrum sensing of digital video broadcasting-second generation terrestrial (DVB-T2) signals in different fading environments with energy detection (ED) is considered. ED is known to achieve an increased ... -
Spectrum Sensing of DVB-T2 Signals using a Low Computational Noise Power Estimation
(2018-08-28)Cognitive radio is a promising technology that answers the spectrum scarcity problem arising from the proliferation of wireless networks and mobile services. In this paper, spectrum sensing of digital video broadcasting-second ... -
Speech errors and the phonological similarity effect in short-term memory: evidence suggesting a common locus
(2007)In three experiments, we tested the hypothesis that those errors in immediate serial recall (ISR) that are attributable to phonological confusability share a locus with segmental errors in normal speech production. In the ... -
Speech-Based Real-Time Subtitling services
(2004)Recent advances in technology have led to the availability of powerful speech recognizers at low cost and to the possibility of using speech interaction in a variety of new and exciting practical applications. The purpose ... -
Speedy services : time, usability and E-Commerce
(University of Hertfordshire, 1999)Times play a vital role in human-computer interaction. However, when interaction takes place over a network, as is the case with e-commerce, it is impossible to guarantee that temporal requirements will be met. Therefore ... -
Spelling and Reading Representations in Children
(2008-07-24)This thesis sought to conceptualise children’s spelling and reading representations in a novel way based upon the implicit-explicit framework proposed by the Representational-Redescription (RR) model (Karmiloff-Smith, ... -
Spelling development in young children: a case of Representational Redescription?
(2007)Two experiments explored children’s spelling development in the context of the Representational-Redescription Model (Karmiloff-Smith, 1992). Fifty-one 5-7 year old children (experiment one) and 44 5-6 year olds (experiment ... -
Spheroidal post-mergers in the local Universe
(2012-03-01)Galaxy merging is a fundamental aspect of the standard hierarchical galaxy formation paradigm. Recently, the Galaxy Zoo project has compiled a large, homogeneous catalogue of 3373 mergers, through direct visual inspection ... -
Spice drugs : los cannabinoides como nuevas drogas de diseño
(2009)Some smokable herbal mixtures under the brand name Spice drugs have been sold on the Internet and in specialised shops (smart shops) since 2004. The mixtures are advertised as an exotic incense blend which releases a rich ... -
"Spice", "Kryptonite", "Black Mamba": An overview of brand names and marketing stragtegies of Novel Psychoactive Substances on the Web
(2014)Novel Psychoactive Substances (NPSs) are often sold online as “legal” and “safer” alternatives to International Controlled Drugs (ICDs) with captivating marketing strategies. Our aim was to review and summarize such ... -
Spike pattern recognition by supervised classification in low dimensional embedding space
(2016-06-01)Epileptiform discharges in interictal electroencephalography (EEG) form the mainstay of epilepsy diagnosis and localization of seizure onset. Visual analysis is rater-dependent and time consuming, especially for long-term ... -
Spike sorting for large, dense electrode arrays
(2016-03-29)Developments in microfabrication technology have enabled the production of neural electrode arrays with hundreds of closely spaced recording sites, and electrodes with thousands of sites are under development. These probes ... -
Spike-timing dependent plasticity facilitates excitatory/inhibitory disbalances in early phases of tinnitus manifestation
(2012)The majority of tinnitus cases are related to cochlear dysfunction, leading to altered peripheral input to the central auditory system. These alterations are believed to diminish the difference in activation during on- and ... -

Spinal Muscle Atrophy Disease Modelling as Bayesian Network
(2021-12-24)We investigate the molecular gene expressions studies and public databases for disease modelling using Probabilistic Graphical Models and Bayesian Inference. A case study on Spinal Muscle Atrophy Genome-Wide Association ... -
Spinners and the Law : Regulating yarn standards in the English worsted industries, 1550-1800
(2013-11)The Worsted Acts, passed between 1777 and 1791, established semi-official industrial police forces in nearly a third of the counties of England, charged with detecting and prosecuting fraudulent reeling of worsted yarn by ...
