Exploration via Structured Triangulation by a Multi-Robot System with Bearing-Only Low-Resolution Sensors [PDF]

arXiv, 2014
This paper presents a distributed approach for exploring and triangulating an unknown region using a multi- robot system. The objective is to produce a covering of an unknown workspace by a fixed number of robots such that the covered region is maximized, solving the Maximum Area Triangulation Problem (MATP).

Unwrapping the Ciliary Coat: High‐Resolution Structure and Function of the Ciliary Glycocalyx

Advanced Science, EarlyView.
The ciliary membrane is decorated in glycosylated proteins that define the interaction of the cilium with its environment. The main component of the ciliary coat of the green alga Chlamydomonas reinhardtii, FMG1, is characterized by cryo‐electron microscopy, proteomics, and live cell microscopy with flow‐based adhesion assays.
