A stability theorem on cube tessellations

open access: yesJournal of Computational Geometry, 2018
It is shown that if a $d$-dimensional cube is decomposed into $n$ cubes, the side lengths of which belong to the interval $(1 − \frac{n}{1/d 1 +1} , 1]$, then $n$ is a perfect $d$-th power and all cubes are of the same size.

Transmitting in the n-dimensional cube

open access: yesDiscrete Applied Mathematics, 1992
It is proved that for any integer \(n\) and for any sequence \(a_ 1,\dots,a_ k\) of \(k=\lceil n/2\rceil\) binary vectors of dimension \(n\) there is a binary vector \(z\) of dimension \(n\) such that the Hamming distance between \(z\) and \(a_ i\) is greater than \(k-i\) for \(i=1,\dots,k\).

The invariants of n-dimensional Rubik's Cube

open access: yes, 2021
It is well known that Rubik's cube has a set of group invariants. These values do not change if any layer was rotated, but they can change in case if some of the cubes were removed from the puzzle, mixed up and returned back. In this paper, we generalize the puzzle to the case of an arbitrary dimension after which we describe all the invariants.

Concave Continuations of Boolean Functions and Some of Their Properties and Applications

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
In this paper, it is proved that for any Boolean function of n variables, there are infinitely many functions, each of which is its concave continuation to the n-dimensional unit cube.

Concave Continuations of Boolean-like Functions and Some of Their Properties

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
In this paper, we present concave continuations of discrete functions defined on the vertices of an $n$-dimensional unit cube, an $n$-dimensional arbitrary cube, and an $n$-dimensional arbitrary parallelepiped.

On the structure, complexity, and depth of the circuits over the basis {&,˅} realizing step Boolean functions

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
The step Boolean function is a function of the algebra of logic of n Boolean variables, n = 1, 2, … , reducing to 1 on all of the sets of an n -dimensional unit cube, the ordinal numbers of which are not lower than the given set.

On regular subgraphs of augmented cubes

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The n-dimensional augmented cube AQn is a variation of the hypercube It is a -regular and -connected graph on vertices. One of the fundamental properties of AQn is that it is pancyclic, that is, it contains a cycle of every length from 3 to In this paper,

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
