A single strand: A simplified approach to DNA origami

open access: yesFrontiers in Chemistry, 2023
Just as a single polypeptide strand can self-fold into a complex 3D structure, a single strand of DNA can self-fold into DNA origami. Most DNA origami structures (i.e., the scaffold-staple and DNA tiling systems) utilize hundreds of short single-stranded

The Symbolic Dynamics Of Multidimensional Tiling Systems [PDF]

open access: yes, 2003
We prove a multidimensional version of the theorem that every shift of finite type has a power that can be realized as the same power of a tiling system.

Randomness and Topological Invariants in Pentagonal Tiling Spaces

open access: yesDiscrete Dynamics in Nature and Society, 2011
We analyze substitution tiling spaces with fivefold symmetry. In the substitution process, the introduction of randomness can be done by means of two methods which may be combined: composition of inflation rules for a given prototile set and tile ...

Dry sand as a specialized layer to improve the acoustic insulation between rooms one above another

open access: yesMateriales de Construccion, 2013
This work presents and analyses the experimental field results of the sound insulation from airborne and impact noise of the horizontal separating elements commonly used in the past, in which a uniform layer of sand was placed on top of the floor ...

Factor Maps Between Tiling Dynamical Systems [PDF]

open access: yes, 1999
. We show that there is no Curtis-Hedlund-Lyndon Theorem for factor maps between tiling dynamical systems: there are codes between such systems which cannot be achieved by working within a finite window. By considering 1-dimensional tiling systems, which

Source code plagiarism detection for PHP language

open access: yesEuropean Journal of Business Science and Technology, 2017
This paper introduces a system for detection of plagiarism in source codes written in the PHP computer language, part of the plagiarism detection tool Anton. We used the greedy string tiling algorithm together with tokenization and hash calculation.

Tensile bond strength of adhesive mortars with hydroxypropyl methyl cellulose and vinyl acetate-ethylene polymers after thermal storage

open access: yesAnais da Academia Brasileira de Ciências, 2023
The properties of adhesive mortars can change due to heating, compromising the durability of the coating systems. The aim of this article was to evaluate the influence of cement and polymer contents on the tensile bond strength of adhesive mortars after ...

One Tile to Rule Them All: Simulating Any Tile Assembly System with a Single Universal Tile [PDF]

open access: yes, 2014
In the classical model of tile self-assembly, unit square tiles translate in the plane and attach edgewise to form large crystalline structures. This model of self-assembly has been shown to be capable of asymptotically optimal assembly of arbitrary shapes and, via information-theoretic arguments, increasingly complex shapes necessarily require ...
