Sensor Evolution In A Homeokinetic System
(2002)We study simulated Braitenberg agents controlled by a homeokinetic dynamic which evolve the ability to discriminate between two different types of objects. The free parameters of the homeokinetic control are varied by an ... -
Sensor materials for the detection of proteases
(2009-03-15)The concept of generic and tunable sensor materials for the detection of proteases based on the thin film degradation of peptide cross-linked dextran hydrogels was explored. Hydrogel cross-links were formed via simple imine ... -
Sensorimotor experience and its metrics: informational geometry and the temporal horizon
(Institute of Electrical and Electronics Engineers (IEEE), 2005)We introduce metrics on sensorimotor experience at various temporal scales based on informationtheory. Sensorimotor variables through which the experience of an agent flows are modeled as information sources in the sense ... -
Sensors and Signal Processing
(2013-06-25)In this contribution, an overview of the sensors and signal processing techniques used in vibration measurements is presented. -
Sensory Channel Group and Structure from Uninterpreted Sensor Data
(Institute of Electrical and Electronics Engineers (IEEE), 2004)In this paper we focus on the problem of making a model of the sensory apparatus from raw uninterpreted sensory data as defined by Pierce and Kuipers (Artificial Intelligence 92:169-227, 1997). The method relies on generic ... -
Sensory-motor problems in Autism
(2013-07-01)Despite being largely characterised as a social and cognitive disorder, strong evidence indicates the presence of significant sensory-motor problems in Autism Spectrum Disorder (ASD). This paper outlines our progression ... -
Sentiment Analysis of Teachers Using Social Information in Educational Platform Environments
(2020-03-31)Learners’ opinions constitute an important source of information that can be useful to teachers and educational instructors in order to improve learning procedures and training activities. By analyzing learners’ actions ... -
Sentiment and emotional analysis of risk perception in the Herculaneum Archaeological Park during Covid-19 pandemic
(2022-10-24)This paper proposes a methodology for sentiment analysis with emphasis on the emotional aspects of people visiting the Herculaneum Archaeological Park. The methodology provides a valuable means of continuous feedback on ... -
Sentosa : a feminist ethnography of a psychiatric hospital in Sarawak, East Malaysia
(University of Hertfordshire, 2002)This doctoral thesis is a feminist ethnographic study of psychiatric patients in the State of Sarawak, East Malaysia. The study took place at a psychiatric hospital located in the capital city of Kuching, commencing in ... -
Separation of immunomodulatory and cholesterol-lowering activities of heterocyclic azaspiranes
(1995-02-22)Azaspiranes are novel immunomodulators which are effective in a variety of autoimmune diseases. One azaspirane analog, SK and F 105685 (N,N-dimethyl- 8,8-dipropyl-2-azaspiro [4.5] decane-2-propanamine dihydrochloride), ... -
The separation of the stars in the binary nucleus of the planetary nebula Abell 35
(1998)Using the Planetary Camera on board the Hubble Space Telescope we have measured the projected separation of the binary components in the nucleus of the planetary nebula Abell 35 to be larger than 0.08′′ but less than 0.14′′. ... -
Sequence determination of a quadripartite dsRNA virus isolated from Aspergillus foetidus
(2013-01)Virus infection of Aspergillus foetidus was documented over 40 years ago and was one of the first mycovirus infections described in a filamentous fungus. The virus, named Aspergillus foetidus virus (AfV), contains at least ... -
Sequence determination of a satellite RNA isolated from Aspergillus foetidus
(2015-03)Aspergillus foetidus virus (AfV) has at least two distinct particle types, designated as AfV-fast (F) and AfV-slow (S). AfV-S includes AfV-S1, a victorivirus; AfV-S2, an unclassified satellite RNA; and AfV-S3, a previously ... -
Sequence of RNA-dependent RNA polymerase genes provides evidence for three more distinct mitoviruses in Ophiostoma novo-ulmi isolate Ld
(2006-08-01)Three of the twelve double-stranded (ds) RNAs, dsRNAs 1a, 1b and 3b, which are located in the mitochondria of a diseased isolate, Ld, of the Dutch elm disease fungus, Ophiostoma novo-ulmi have been cDNA cloned and sequenced. ... -
Sequence-specific, RNA-protein interactions overcome electrostatic barriers preventing assembly of satellite tobacco necrosis virus coat protein
(2013-03-25)We have examined the roles of RNA-coat protein (CP) interactions in the assembly of satellite tobacco necrosis virus (STNV). The viral genomic RNA encodes only the CP, which comprises a β-barrel domain connected to a ... -
Sequences in the HSP90 promoter form G-quadruplex structures with selectivity for disubstituted phenyl bis-oxazole derivatives
(2012)The HSP90 protein is an important target in cancer. We report here that stable quadruplex DNAs can be formed from a promoter sequence in the HSP90 gene, on the basis of melting, circular and NMR studies, and show that these ...
