Kartashova, , resonant triads with real amplitudes are counted whereas it can be seen explicitly from the form of dynamical system that wave amplitudes are complex. ... Counting of resonant triads.  states that discrete Rossby/drift wave resonant triads counted by  must have complex amplitudes. ... However, the main problem with counting resonant triads in  is not whether triads with real or complex amplitudes are counted -the first is a subset of the second. ...arXiv:1309.0992v1 fatcat:lrnu4rulyzcvrbaffmwbjppuxu
The terms specify network statistics that are sufficient to represent the probability distribution over the space of networks of that size. Many classes of statistics can be used. ... In this article we describe the classes of statistics that are currently available in the ergm package. ... In an undirected graph these two counts simplify: a triad census counts the number of triads having 0, 1, 2, and 3 edges, and each set of three nodes contributes either zero or one triple (also called ...pmid:18650964 pmcid:PMC2481518 fatcat:ce55tvqbvbfqvlr2ezqbzy6gza

SHED analyzes the N by N sociomatrix by sorting and counting the dyad and triad types. ... The program, a trichotomous ana¬ logue to Leinhardt’s SOCPAC I program (Leinhardt, 1971) counts and sorts the N(N — 1)(N — 2)/6 triads in an N by N sociomatrix into 138 nonisomorphic triad types. ...
In social networks, such edges often form closed triangles, or triads. ... We propose a novel measure of triadic closure for multi-edge networks of social interactions based on a shared partner statistic. ... In such networks, measuring triadic closure can be operationalized by counting triads. ...arXiv:1905.02990v1 fatcat:wcpjvu2et5dmrjifujdrdc6dqm
SHED analyzes the N by N sociomatrix by sorting and counting the dyad and triad types. ... The program, a trichotomous analogue to Leinhardt's SOCPAC I program counts and sorts the N(N -1)(N -2)/6 triads in an N by N sociomatrix into 138 nonisomorphic triad types. ... This notation was adopted in preference to that introduced by Davis and , since trichotomized (positive-indifferent-negative) relations do not lend themselves to identification by dyad type counts followed ...doi:10.3758/bf03205095 fatcat:6ua6sykdpbgzbjyuz3jxolj4xm

One can markedly reduce the number of genotyping assays required by randomly partitioning the case-parent triads into pooling sets of h triads each and creating three pools from every pooling set, one ... Association studies that genotype affected offspring and their parents (triads) offer robustness to genetic population structure while enabling assessments of maternal effects, parent-of-origin effects ...

This difference is not statistically signifi- cant, and the average is 26.32. This bears out the earlier statement that reliability de- pends on total number of particles counted. TABLE III. ... Study of triads shows that 95 times out of 100 the overall range in a triad will not ex- ceed 2.96 times the average difference for a pair. ...
