MATRICE FACTEUR [3 records]

Record 1 2021-05-07

English

Subject field(s)
  • Modern Mathematics
  • Computer Mathematics
DEF

[A] nonzero vector that changes at most by a scalar factor when [a] linear transformation is applied to it.

CONT

When a matrix performs a linear transformation, eigenvectors trace the lines of force it applies to input; when a matrix is populated with the variance and covariance of the data, eigenvectors reflect the forces that have been applied to the given.

French

Domaine(s)
  • Mathématiques modernes
  • Mathématiques informatiques
CONT

Un vecteur propre a donc une direction privilégiée par la matrice, alors que la valeur propre représente le facteur d’étirement(ou de compression) dans cette direction.

Record 2 2019-06-04

English

Subject field(s)
  • Genetics
  • Molecular Biology
  • Microbiology and Parasitology
DEF

A ring-shaped protein that encircles double-stranded DNA and slides spontaneously across it, conferring high processivity on DNA polymerases.

French

Domaine(s)
  • Génétique
  • Biologie moléculaire
  • Microbiologie et parasitologie
CONT

Chez les bactéries, les eucaryotes et les archées, la processivité et l'efficacité de la synthèse de l'ADN nécessite une protéine en forme d’anneau, appelée «protéine à pince coulissante» ou «facteur de glissement»(DNA sliding clamp) qui encercle l'ADN et qui maintient la polymérase sur la matrice ADN […]

Record 3 2012-10-15

English

Subject field(s)
  • Environmental Studies and Analyses
  • Statistics
CONT

Concerning the low capacity of active dispersion of the "Ae. aegypti" mosquito ..., it was expected that the existence of a road connecting Piura and Lima ... could be an ultimate passive dispersion factor for the existence and maintenance of the genic flow and the genetic proximity between the populations of the two locations.

OBS

dispersion factor: literal translation of the German term "Streuungsursache" present on this record.

French

Domaine(s)
  • Études et analyses environnementales
  • Statistique
CONT

[Pendant le] calcul des coefficients du modèle, le logiciel S-Plus évalue également la matrice de covariance des coefficients. Si la dispersion est laissée libre(ex. que l'on n’ impose pas sa valeur à 1), cette matrice doit être corrigée par le facteur de dispersion obtenu de la régression.

OBS

facteur de dispersion : traduction littérale du terme allemand «Streuungsursache» qui figure sur la présence fiche.
