Quantifying Glial-Glial Tiling Using Automated Image Analysis in Drosophila
Not only do glia form close associations with neurons throughout the central nervous system (CNS), but glial cells also interact closely with other glial cells.

Packing problems on generalised regular grid: Levels of abstraction using integer linear programming
Packing a designated set of shapes on a regular grid is an important class of operations research problems that has been intensively studied for more than six decades. Representing a d-dimensional discrete grid as Zd, we formalise the generalised regular

Towards a modular and scalable holographic display
Holographic three-dimensional (3D) display can be made very large using a modular system that allows seamless spatial tiling of multiple coarse integral holographic images.

Constructing and Visualizing Uniform Tilings
This paper describes a system which takes user input of a pattern of regular polygons around one vertex and attempts to construct a uniform tiling with the same pattern at every vertex by adding one polygon at a time.

ACF: An Armed CCTV Footage Dataset for Enhancing Weapon Detection
Thailand, like other countries worldwide, has experienced instability in recent years. If current trends continue, the number of crimes endangering people or property will expand.

Simple cell-cell interactions can give rise to complex cellular patterns. For example, neurons of the same type can interact to create a complex patchwork of non-overlapping dendrite arbors, a pattern known as dendrite tiling.

Aperiodic spin chains at the boundary of hyperbolic tilings
In view of making progress towards establishing a holographic duality for theories defined on a discrete tiling of the hyperbolic plane, we consider a recently proposed boundary spin chain Hamiltonian with aperiodic couplings that are chosen such as to ...

Snake-Deterministic Tiling Systems [PDF]
The concept of determinism, while clear and well assessed for string languages, is still matter of research as far as picture languages are concerned. We introduce here a new kind of determinism, called snake, based on the boustrophedonic scanning strategy, that is a natural scanning strategy used by many algorithms on 2D arrays and pictures.

Tiling Systems versus Tile Rewriting Grammars
Two formal models of pictures, i.e., two dimensional (2D) languages are compared: tiling systems and tile rewriting grammars, which resp. extend to 2D the regular and context-free languages. Two results extending classical language properties into 2D are proved. First, non-recursive tile writing grammars (TRG) coincide with tiling systems (TS). Second,

Test generation from recursive tile systems [PDF]
SUMMARYThis paper explores the generation of conformance test cases for recursive tile systems (RTSs) in the framework of the classical ioco testing theory. The RTS model allows the description of reactive systems with recursion and is very similar to other models like pushdown automata, hyperedge replacement grammars or recursive state machines.
