divergence

1. The act or state of moving off in different directions from a point.
2. The departure from each other of two processes, modes of action or courses of evolution.
3. In genetics, the degree, usually expressed as a percentage, to which two related DNA lengths differ in nucleotide sequences, or two similar proteins differ in amino acid sequence.

divergence

1. Movement of the eyes turning away from each other. 2. Characteristic of a pencil of light rays, as when emanating from a point source. Syn. negative convergence. See vergence.
divergence excess A high exophoria at distance associated with a much lower exophoria at near. It may occasionally give rise to diplopia in distance vision.
fusional divergence A movement of the eyes away from each other in response to retinal disparity, in order to restore single binocular vision. It occurs most commonly when induced by a base-in prism.
divergence insufficiency A high esophoria at distance associated with esophoria at near. It often gives rise to symptoms of asthenopia in both distance and near vision.
divergence paralysis See divergence paralysis.
vertical divergence Relative vertical movement between the two eyes.

Therefore, the goal of this study was to quantify the genetic divergence of 40 cowpea genotypes by means of Integrated Multivariate Analysis for the purpose of assisting the parents choice and for new cultivars development..
Furthermore, it possesses enough sequence divergence required for species discrimination (Hebert et al., 2003 b).
We can see that [J.sub.R](P,Q) = 2[F(Q,P) + G(Q, P)], [DELTA](P,Q) = 2[1 - W(P,Q)], h(P, Q) = 1 - B(P,Q), and I(P,Q) = (1/2)[F(P,Q) + F(Q,P)], where W(P,Q) = 2 [[summation].sup.n.sub.i=1] ([p.sub.i][q.sub.i]/([p.sub.i] + [q.sub.i])) is the harmonic mean divergence, B(P, Q) = [[summation].sup.n.sub.i=1] [square root of [p.sub.i][q.sub.i]] is the geometric mean divergence, and F(P,Q) = [[summation].sup.n.sub.i=1] [p.sub.i] log(2[p.sub.i]/([p.sub.i] + [q.sub.i])) is the relative JS divergence [5].
To investigation of divergence and evolution of maize BAG Genes, here a total of 13 members for BAG genes were computationally identified in the maize genome.
En tete des articles de divergence celui du systeme parlementaire en Egypte, ainsi que les articles sur le systeme d'election aux legislatives (par liste ou uninominal), et si l'on garderait ou non, le taux consacre aux paysans et aux ouvriers.
In addition to other approaches for strengthening students' understanding of evolution, dating nodes on phylogenetic trees may be very useful for helping students visualize evolutionary history and processes of species divergence using an online tool, "TimeTree: The Timescale of Life" (Hedges et al., 2006; Hedges & Kumar, 2009; http://timetree.org).
The advent of "molecular dating" has enabled organismal entomologists and molecular evolutionary biologists to use DNA sequence data to obtain molecular dates for insect divergences. For a group as speciose as Insecta, the potential of such a method to confirm or contradict fossil-based estimates of the origins of herbivory, mutualism, flight, parasitism and other remarkable insect behaviors is intriguing.
- Positive divergence alerts us to the fact that downside momentum is fading and the potential for a long trade is setting up.
A fuller description of the properties of Bregman divergences can be found in [2].
An important problem is to propose some divergences statistics for procedure tests.
In an article in Le Monde (23 November), Henri Tincq, an expert on religious issues, divides those who answer this question into three categories: the die-hards, who think that dialogue is impossible, that the divergences are too great and that it cannot lead anywhere; the sceptics, who have tried dialogue and been discouraged; and the artless, who believe that dialogue will enable us to evolve together and overcome our divergences.
Converging Divergences is a carefully researched and well-argued book.
