On trees, tanglegrams, and tangled chains [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
Tanglegrams are a class of graphs arising in computer science and in biological research on cospeciation and coevolution. They are formed by identifying the leaves of two rooted binary trees. The embedding of the trees in the plane is irrelevant for this

Techniques for handling clustered binary data [PDF]

open access: yes, 2002
Bibliography : leaves 143-153.Over the past few decades there has been increasing interest in clustered studies and hence much research has gone into the analysis of data arising from these studies.

Enumeration of Binary Trees and Universal Types [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
Binary unlabeled ordered trees (further called binary trees) were studied at least since Euler, who enumerated them. The number of such trees with n nodes is now known as the Catalan number.

RepB C-terminus mutation of a pRi-repABC binary vector affects plasmid copy number in Agrobacterium and transgene copy number in plants. [PDF]

open access: yesPLoS ONE, 2018
A native repABC replication origin from pRiA4b was previously reported as a single copy plasmid in Agrobacterium tumefaciens and can improve the production of transgenic plants with a single copy insertion of transgenes when it is used in binary vectors ...

Maximizing binary interactome mapping with a minimal number of assays

open access: yesNature Communications, 2019
Comprehensive mapping of binary protein-protein interactions requires to combine several complementary assays. Here, the authors show that complete coverage could be reached with a minimal number of assays as long as they explore various experimental ...

Correlation properties of binary pseudorandom sequence based on residue number system

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2019
It proposed to synthesize the stochastic code structures based on residue number system, which allows to form ensembles with acceptable correlation properties, cryptographic difficulty level of formed ensembles, depending on key, and with any length of ...

Analysis of group randomized trials with multiple binary endpoints and small number of groups. [PDF]

open access: yesPLoS ONE, 2009
The group randomized trial (GRT) is a common study design to assess the effect of an intervention program aimed at health promotion or disease prevention. In GRTs, groups rather than individuals are randomized into intervention or control arms.

A Revised Model for Magneto Convection in Binary Nanofluids [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2019
The paper presents double-diffusive nanofluid convection under magnetic field using more realistic revised model in which boundaries are assumed to have zero nanoparticle flux.

Experimental investigation of effective atomic numbers for some binary alloys

open access: yesNuclear Engineering and Technology, 2017
In the present work, the gamma ray backscattering technique was used to determine the effective atomic numbers for certain binary alloys. With the help of a muffle furnace, the binary alloys were synthesized using the melt quenching technique with ...

Holonomic equations and efficient random generation of binary trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
Holonomic equations are recursive equations which allow computing efficiently numbers of combinatoric objects. Rémy showed that the holonomic equation associated with binary trees yields an efficient linear random generator of binary trees.
