Trace splittings in C*-algebras of tiling systems via colourings [PDF]
, 2002 Tiles of a hierarchical tiling system are coloured with given colours. The resulting system implements colour symmetries and prescribed frequencies and is itself a hierarchical system whose prototile types admit an elegant description. The frequencies of

Negative refraction and tiling billiards
, 2018 We introduce a new dynamical system that we call tiling billiards, where trajectories refract through planar tilings. This system is motivated by a recent discovery of physical substances with negative indices of refraction.

Iterative Selection of DNA Nanostructures for Cellular Uptake
Advanced Materials, EarlyView.DNA nanostructures are promising cell targeting delivery vehicles for therapeutics, but the targeting behavior is not fully understood. In this study, libraries of DNA nanostructures that can be amplified and sequenced are combined with cellular uptake as a selection pressure to iteratively refine DNA structures taken up in cells to better understand ...

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 ...

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection
Advanced Materials Technologies, EarlyView.A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Optimized viewport‐adaptive 360‐degree video streaming
CAAI Transactions on Intelligence Technology, 2021 Because of the rapid growth of head‐mounted displays and 5G networking deployment, 360‐degree video has become increasingly popular. To generate the real experience of a virtual environment, 360‐degree videos require an ultrahigh resolution and frame ...

Fractal Tilings from Iterated Function Systems [PDF]
Discrete & Computational Geometry, 2014 Iterated function systems (IFS) introduced in 1981 by \textit{J. E. Hutchinson} in his famous paper [``Fractals and self-similarity'', Indiana Univ. Math. J. 30, 713--747 (1981; Zbl 0598.28011)], are the main generators of fractals as attractors of the respective IFSs on a complete metric space.
