Shortest Paths in Triangular Grids with Neighbourhood Sequences
, 2003 In this paper we analyse some properties of the triangular and hexagonal grids in the 2D digital space. We define distances based on neighbourhood relations that can be introduced in these grids.

Studying cities to learn about minds: some possible implications of space syntax for spatial cognition [PDF]
, 2009 What can we learn of the human mind by examining its products? The city is a case in point. Since the beginning of cities human ideas about them have been dominated by geometric ideas, and the real history of cities has always oscillated between the ...

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells
Advanced Functional Materials, EarlyView.Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,
