What's the difference between topology and typology?

Topology


Definition:

  • (n.) The art of, or method for, assisting the memory by associating the thing or subject to be remembered with some place.

Example Sentences:

  • (1) The scheme is based on topological information, i.e.

  • (7) Then, a 'hyperstructure matrix' is generated, containing the unique topological relationship between every pair of regions.
  • (8) Linear DNA substrates in which pairing is topologically restricted to a paranemic joint also follow this relationship.

  • (10) The fluorescence properties of Hoechst 33342 (HO 33342) were examined with plasmid pBR322 in the supercoiled (Form I) or relaxed covalently closed circular (Form Io) conformation in order to determine whether qualitative or quantitative differences in fluorescence properties might provide an assay for topological states of DNA.
  • (11) An exhaustive search of all possible trees also supported this topology, although one haplotype had to be eliminated from this analysis to save computer time.
  • (12) This superfamily of proteins is predicted to share the topology of the seven transmembrane helices of bacteriorhodopsin (BR), even though no significant sequence homology had been identified.
  • (13) These data demonstrate the utility of this approach for determining membrane protein topology and extend potential applications to include at least some proteins not normally expressed in E. coli.
  • (14) The unique topology of the products indicates that resolvase fixes the sum of the number of supercoils between recombination sites at synapsis and the number of such supercoils lost or gained during strand exchange.
  • (15) Such explanations are possible because the relatively few structural proteins of the erythrocyte are regularly distributed over the entire cytoplasmic surface of the cell membrane and because the well-understood topological associations of these proteins seem to be stable in comparison with the time required for the cell to change shape.
  • (16) The objectives of the present investigations were to document a composite, new approach for the evaluation of the structure-function dependencies of proteins based on the analysis of the informational content of the primary amino acid sequence as well as the topological and functional regions of a protein.
  • (17) When the input topology is supercoiled, high levels of transcription are observed, whereas input relaxed DNA is transcribed to a much lower extent.
  • (18) It is believed that one or more basic residues at the extreme amino terminus of precursor proteins and the lack of a net positive charge immediately following the signal peptide act as topological determinants that promote the insertion of the signal peptide hydrophobic core into the cytoplasmic membrane of Escherichia coli cells with the correct orientation required to initiate the protein export process.
  • (19) We observe that the effect of osmotic shock is an elevation of superhelical tension; quantitative comparison with changes in plasmid linking number indicates that the alteration in DNA topology is all unconstrained.
  • (20) Anomalous correspondence most probably has its seat where the retinal topology is not exact, i.e., where the binocular receptive fields are very large and encompass the corpus callosum, such as in area 20 or 21.

Typology


Definition:

  • (n.) A discourse or treatise on types.
  • (n.) The doctrine of types.

Example Sentences:

  • (1) Typological and archaeological investigations indicate that the church building represents originally the hospital facility for the lay brothers of the monastery, which according to the chronicle of the monastery was built in the beginning of the 14th century.
  • (2) The typology developed in two previous surveys of illicit heroin products is applicable to many of the samples studied in this work, although significant changes have occurred in the chemical profile of illicit heroin products from certain geographical regions.
  • (3) Five cluster types emerged, which were similar to typologies found in studies with alcoholic inpatients.
  • (4) A typology of the social climates of group residential facilities for older people was developed by a cluster analysis of seven social climate attributes obtained on a national sample of 235 nursing homes, residential care facilities, and congregate apartments.
  • (5) These language differences are just one sign that there is little correspondence between the published typologies.
  • (6) Finally, some of the principal issues raised by this typology are discussed.
  • (7) The findings support and extend theories of biologically-based and bio-psycho-social typology.
  • (8) The authors compare the factors, parameters and typology of the clinical polymorphism of epilepsy in two groups of patients from an epidemiological sample: 265 patients with a synchronous and 251 patients with an asynchronous circadian pattern of attacks.
  • (9) A typology of families in terms of the way they relate to health care and its providers.
  • (10) The results are discussed in relation to other typological approaches to unipolar depression.
  • (11) Finally, by analyzing data derived from primary and secondary source materials on 81 healing systems or techniques identifying themselves with the new age, a typology of new age healing itself is inductively generated.
  • (12) The study tested the hypothesis that the RD would yield higher estimates of average alcohol consumption and of "heavy drinking" as defined by NIAAA typology (average two or more drinks per day) and of "peak drinking," a Q-F standard consisting of five or more drinks at least once per week.
  • (13) was the best variable in evaluating the relationship between vertical typology and head posture.
