	Selectivity - Wikipedia, the free encyclopedia
		Also the words selectiveness, refinement and discrimination are used.
		In a database index, a measure for how many records will be retrieved for a given value of an attribute.
		In natural sciences selectivity characterises either how selective reactions occur amongst several pathways which are typical in particular for organic reactions; or selectivity characterises how selective one particular compound is recognized, or bound, by something else, e.g.

	Frequency modulation - Wikipedia, the free encyclopedia
		FM also keeps the tape at saturation level, and therefore acts as a form of noise reduction, and a simple limiter can mask variations in the playback output, and the FM capture effect removes print-through and pre-echo.
		FM receivers inherently exhibit a phenomenon called capture, where the tuner is able to clearly receive the stronger of two stations being broadcast on the same frequency.
		Problematically, however, frequency drift or lack of selectivity may cause one station or signal to be suddenly overtaken by another on an adjacent channel.

	Electronic journals and scholarly communication: a citation and reference study
		The purpose of the research is to assess the impact of electronic journals (e-journals) on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic.
		Although electronic journals (or e-journals) have been under development since 1976 (Turoff and Hiltz, 1982), e-journals in their non-experimental phase did not begin until the 1990s, with a few exceptions.
		E-journals selected from the ARL directory were taken from the section entitled "Electronic journals, magazines, and zines" and identified there as "peer-reviewed." e-journals selected from the Mecklermedia directory were taken from the section entitled "Electronic journals and newsletters" and identified there as "refereed." All e-journals meeting these criteria became members of the sample.

	The lowest canonical denominator: electronic literary texts, and the role of the information professional
		When faced with a situation in which electronic texts either could not be found, or not in the right editions, or without the necessary metadata it seemed that students lost confidence in them, and most crucially in the whole business of using electronic text analysis techniques in their work.
		It may be that electronic projects like Brown Women Writers, which concentrates on the production of non-canonical and little known writers will multiply, as well as projects run by teams of scholars who will produce their own scholarly editions of writers in whom they themselves are interested, such as the excellent Rosetti Archive.
		Electronic publication is not just the means of providing fast access and searching for reference databases, it also makes it easier for users to gain access to rare and in some cases fragile texts.

	scf-online.com \| Issue 33 \| R. Daniels: Electronic Noses
		The main motivation for electronic noses is the development of a qualitative, low-cost, real-time, and portable method to perform reliable, objective, and reproducible measures of volatile compounds and odors.
		Although electronic noses are systems that, just like the human nose, try to characterize different gas mixtures their performance is far from that of our olfactory sense.
		Often the selectivity of the polymer films is altered by using polymer bilayers consisting of polypyrrole and polyaniline or poly (3-methylthiophene).

	The Electronic Nose at IIT
		The "electronic nose" is a relatively new tool that may be used for safety, quality, or process monitoring, accomplishing in a few minutes procedures that may presently require days to complete.
		The electronic nose consists of two components, (1) an array of chemical sensors (usually gas sensors) and (2) a pattern-recognition algorithm.
		The term "electronic nose" was first used in a jocular sense during our early work with sensor arrays in the 1980's.

	M & S - page 1
		On disordered surfaces, the energy spectrum of SES is quasi-continuous, and, while the sorption of molecules may be fairly selective, this selectivity in sorption is not reflected in the sensor response.
		The selectivity therefore depends on the overlap of the rich vibrational spectra between the dye and the analyte molecule.
		When there is resonance between electron transitions in molecular phase, the energy of an excited electron from a donor molecule is transferred to vibrational modes of this molecule and then to adjacent acceptor molecules, if their vibrational spectra overlap.

	Materials and Processing Issues in Nanostructured Semiconductor Gas Sensors
		Selectivity is dependent on many parameters, such as gas adsorption and co-adsorption mechanisms, surface reaction kinetics, and electron transfer to or from the conduction band of the semiconductor.
		In practice, selectivity is achieved by enhancing gas adsorption or promoting specific chemical reactions via catalytic or electronic effects using bulk dopants, surface modification methods, and by the addition of metallic clusters or oxide catalysts.
		For instance, the selectivity of chemical sensors can be strongly influenced by the addition of metal clusters such as platinum and palladium, resulting in an increase in the sensor selectivity to reducing gases, such as CO.

	Electrochemistry Encyclopedia --- Electrochemical nose
		An "electronic or artificial nose" is an instrument, which comprises a sampling system, an array of chemical gas sensors with differing selectivity, and a computer with an appropriate pattern-classification algorithm, capable of qualitative and/or quantitative analysis of simple or complex gases, vapors, or odors.
		The term, "electronic nose" or "E-nose" has come into common usage as a generic term for an array of chemical gas sensors incorporated into an artificial olfaction device, after its introduction in the title of a landmark conference on this subject in Iceland in 1991.
		An electronic nose is an instrument comprised of three parts: (a) a sampling system, (b) an array of chemical gas sensors producing an array of signals when confronted with a gas, vapor, or odor, and (c) an appropriate pattern-classification system.

		So, a protocol of preparation methods for the substrate is needed to define their electronic characteristics and to establish the importance of the oxygen layer in determining these properties.
		The structure of the organic adlayer (the "nose" of the sensor) is strongly dependent on the substrate chemical properties, its morphology, on the nature of the chemical bonds between the substrate and the adsorbate, and on the intermolecular forces in the layer.
		Electronic measurements will be performed on the MOCSER coated with the porphyrin in order to establish the effect of the porphyrin itself on the current through the MOCSER.

	The Impact of Electronic Journals on Scholarly Communication A Reference and Citation Study (Site not responding. Last check: )
		For an electronic journal article to be cited, especially in a print publication, the lag time in conventional print publishing and in the research process itself must be considered.
		Perhaps the most significant of all the findings of this research was that the great majority of the electronic journals studied have been cited seldom or not at all by the mainstream print journals that comprise the source journals of the ISI databases.
		Electronic journal publishers can gain some information regarding use by recording the number of subscriptions to an electronic journal or the number of times articles are accessed or downloaded from host servers.

	The Diels-Alder Reaction
		Electronic Effects: Most successful Diels-Alder reactions involve an electronic imbalance between diene and dienophile - usually the diene is electron rich (the donor) and the dienophile is electron poor (the acceptor).
		Alkyl groups on the dienophile are especially problematic because the electronic and steric effects are in the same direction.
		This is a consequence of the lowering of the LUMO of the dienophile by the increased electron deficiency caused by the Lewis acid, and changes in the orbital coefficients which cause stronger secondary orbital interactions and larger regiochemical preference.

	Dutycalc Newsletter - January 1998.
		If an import is flagged during selectivity, a request for original import documentation is automatically sent from the U.S. Customs office where the drawback claim has been filed to the Customs office where the import entry is held.
		If selectivity flags an import and the claim passes the cursory review, the claim is filed awaiting receipt of the original import documentation.
		In the event that selectivity flags an import and the claim does not pass the cursory review, it is filed until the obvious errors on the claim have been rectified and the import documentation has been received.

	Method of etching a dielectric material in the presence of polysilicon - Patent 6740571
		Dielectric material 160 between the gate structures in first region 101 is etched with high dielectric-to-polysilicon selectivity to expose the polysilicon of the gate structures with minimal polysilicon loss.
		A higher dielectric-to-polysilicon selectivity indicates less polysilicon is etched away when etching away comparable amounts of the dielectric.
		However, dielectric-to-polysilicon selectivity is increased in the aforementioned three examples, from about 11 to about 89.6, from about 8.9 to about 43.1, and from about 5.4 to about 133, respectively.

	eBay Guides - VHF DSC Marine Radio Buying Guide
		The two main factors you need to decide in selecting a marine radio is whether it is fixed mount or handheld, and the level of channel selectivity.
		Selectivity is the ability of the radio to focus in on a specific signal and ignore the nearby signals.
		The greater the selectivity, the clearer you'll receive signals when the airwaves are crowded with signals, and the more you'll pay.
