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.

The Precision-Recall Plot Is More Informative than the ROC Plot When Evaluating Binary Classifiers on Imbalanced Datasets

open access: yesPLoS ONE, 2015
Binary classifiers are routinely evaluated with performance measures such as sensitivity and specificity, and performance is frequently illustrated with Receiver Operating Characteristics (ROC) plots.

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.

Dynamics and Interactions of Binaries and Neutron Stars in Globular Clusters [PDF]

open access: yes, 1994
We model the dynamics of test binaries in isotropic, multi-mass models of galactic globular clusters. The evolution of binary orbits through the cluster potentials is modeled, including second order diffusion terms, and probabilities for close encounters

Bayesian inference for compact binary coalescences with bilby: validation and application to the first LIGO–Virgo gravitational-wave transient catalogue [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
Gravitational waves provide a unique tool for observational astronomy. While the first LIGO–Virgo catalogue of gravitational-wave transients (GWTC-1) contains 11 signals from black hole and neutron star binaries, the number of observations is ...

On the non-minimality of the largest weight codewords in the binary Reed-Muller codes [PDF]

open access: yes, 2011
The study of minimal codewords in linear codes was motivated by Massey who described how minimal codewords of a linear code define access structures for secret sharing schemes.

BiEntropy, TriEntropy and Primality

open access: yesEntropy, 2020
The order and disorder of binary representations of the natural numbers < 28 is measured using the BiEntropy function. Significant differences are detected between the primes and the non-primes.

Binomial Number System

open access: yesApplied Sciences, 2021
This paper presents and first scientifically substantiates the generalized theory of binomial number systems (BNS) and the method of their formation for reliable digital signal processing (DSP), transmission, and data storage.
