Expected Number of Distinct Subsequences in Randomly Generated Binary Strings [PDF]
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

Supercongruences involving Apéry-like numbers and binomial coefficients
Let $ \{S_n\} $ be the Apéry-like sequence given by $ S_n = \sum_{k = 0}^n\binom nk\binom{2k}k\binom{2n-2k}{n-k} $. We show that for any odd prime $ p $, $ \sum_{n = 1}^{p-1}\frac {nS_n}{8^n}{\equiv} (1-(-1)^{\frac{p-1}2})p^2\ (\text{ mod}\ {p^3}) $. Let

Weber number and the outcome of binary collisions between quantum droplets
A theoretical analysis of binary collisions of quantum droplets under feasible experimental conditions is reported. Droplets formed from degenerate dilute Bose gases made up from binary mixtures of ultracold atoms are considered. Reliable expressions for

"Exotic" binary number systems for rings of Gauss and Eisenstein integers [PDF]
The paper considers nonstandard binary number systems for rings of Gauss and Eisenstein integers. The principal difference ("exoticism") of such number systems from the canonical number systems introduced by I.

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

High-Speed Binary-to-Residue Converter Design Using 2-Bit Segmentation of the Input Word
In this paper a new approach to the design of the high-speed binary-to-residue converter is proposed that allows the attaining of high pipelining rates by eliminating memories used in modulo m generators. The converter algorithm uses segmentation of the

Binary Companions of Evolved Stars in APOGEE DR14: Search Method and Catalog of ∼5000 Companions [PDF]
Multi-epoch radial velocity measurements of stars can be used to identify stellar, substellar, and planetary-mass companions. Even a small number of observation epochs can be informative about companions, though there can be multiple qualitatively ...

Stability of Characteristics of Physical Random Number Generators
The development of technologies leads to the need of revising the methods used to obtain cryptographic keys. The randomness parameters of sequences generated by physical random sequence generators are affected by the physical parameters of the recording ...

On the binary expansions of algebraic numbers [PDF]
Using concepts from additive number theory and results on binary evaluations and partial series, the authors prove that for a real algebraic number \(y\) of degree \(D> 1\) the number \(\#(|y|, N)\) of 1-bits in the expansion of \(|y|\) through bit position \(N\) is greater than \(CN^{1/D}\), where \(C> 0\) is a number depending only on \(y\), and \(N\)
