Expected Number of Distinct Subsequences in Randomly Generated Binary Strings
, 2018 When considering binary strings, it's natural to wonder how many distinct subsequences might exist in a given string. Given that there is an existing algorithm which provides a straightforward way to compute the number of distinct subsequences in a fixed

Binary sequence detector uses minimum number of decision elements [PDF]
, 1966 Detector of an n bit binary sequence code within a serial binary data system assigns states to memory elements of a code sequence detector by employing the same order of states for the sequence detector as that of the sequence generator when the linear ...

The shape of random tanglegrams [PDF]
, 2016 A tanglegram consists of two binary rooted trees with the same number of leaves and a perfect matching between the leaves of the trees. We show that the two halves of a random tanglegram essentially look like two independently chosen random plane binary ...

Close binary systems among very low mass stars and brown dwarfs
, 2005 Using Monte Carlo simulations and published radial velocity surveys we have constrained the frequency and separation (a) distribution of very low mass star (VLM) and brown dwarf (BD) binary systems. We find that simple Gaussian extensions of the observed

The binary fraction of planetary nebula central stars I. A high-precision, I-band excess search
, 2012 In an attempt to determine how many planetary nebulae derive from binary interactions, we have started a project to measure their unbiased binary fraction.

The asymptotic number of binary codes and binary matroids [PDF]
SIAM Journal of Discrete Mathematics 19 (2005) 691-699, 2004 The asyptotic number of nonequivalent binary n-codes is determined. This is also the asymptotic number of nonisomorphic binary n-matroids. The connection to a result of Lefmann, Roedl, Phelps is explored. The latter states that almost all binary n-codes have a trivial automorphism group.

On the frequency of close binary systems among very low-mass stars and brown dwarfs
, 2005 We have used Monte Carlo simulation techniques and published radial velocity surveys to constrain the frequency of very low-mass star (VLMS) and brown dwarf (BD) binary systems and their separation (a) distribution.

The Origins of Blue Stragglers and Binarity in Globular Clusters [PDF]
, 2012 (abridged) We use newly available empirical binary fractions for globular clusters to carry out a direct test of the binary evolution hypothesis, and of collisional channels that involve binary stars. More specifically, using the previously reported correlation between blue straggler numbers and core mass as a benchmark, we test for correlations with ...
