Tiling systems and 2-graphs associated to textile systems [PDF]

, 2014
This thesis concerns dynamical systems called tiling systems, and combinatorial structures called 2-graphs associated to textile systems. Textile systems were developed as a means of defining and studying two dimensional dynamical systems called shift ...

Parametric multi-level tiling of imperfectly nested loops [PDF]

, 2009
Tiling is a crucial loop transformation for generating high performance code on modern architectures. Efficient generation of multilevel tiled code is essential for maximizing data reuse in systems with deep memory hierarchies.

E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure

Advanced Materials, EarlyView.
The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...

Structural transitions in vortex systems with anisotropic interactions

New Journal of Physics, 2018
We introduce a model of vortices in type-II superconductors with a four-fold anisotropy in the vortex–vortex interaction potential. Using numerical simulations we show that the vortex lattice undergoes structural transitions as the anisotropy is ...

The dawning era of comprehensive transcriptome analysis in cellular microbiology

Frontiers in Cellular and Infection Microbiology, 2010
Bacteria rapidly change their transcriptional patterns during infection in order to adapt to the host environment. To investigate host-bacteria interactions, various strategies including the use of animal infection models, in vitro assay systems and ...

Motion planner for a Tetris-inspired reconfigurable floor cleaning robot

International Journal of Advanced Robotic Systems, 2020
Coverage path planning technique is an essential ingredient in every floor cleaning robotic systems. Even though numerous approaches demonstrate the benefits of conventional coverage motion planning techniques, they are mostly limited to fixed ...

An Algebraic Invariant for Substitution Tiling Systems

Geometriae Dedicata, 1998
We consider tilings of Euclidean spaces by polygons or polyhedra, in particular, tilings made by a substitution process, such as the Penrose tilings of the plane. We define an isomorphism invariant related to a subgroup of rotations and compute it for various examples. We also extend our analysis to more general dynamical systems.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

On the Behavior of Tile Assembly System at High Temperatures [PDF]

Computability, 2012
Behavior of Winfree's tile assembly system (TAS) at high temperatures is investigated in combination with integer programming of a specific form called threshold programming. First, we propose a way to build bridges from the Boolean satisfiability problem (SAT) to threshold programming, and further to TAS's behavior, in order to prove the NP-hardness ...
