Open AccessConnected coordinated motion planning with bounded stretch
We consider the problem of connected coordinated motion planning for a large collective of simple, identical robots: From a given start grid configuration of robots, we need to reach a desired target configura...

Open AccessWorst-Case Optimal Covering of Rectangles by Disks
We provide the solution for a fundamental problem of geometric optimization by giving a complete characterization of worst-case optimal disk coverings of rectangles: For any

Open AccessPacking Disks into Disks with Optimal Worst-Case Density
We provide a tight result for a fundamental problem arising from packing disks into a circular container: The critical density of packing disks in a disk is 0.5. This implies that any set of (not necessarily e...

Open AccessConnected Reconfiguration of Lattice-Based Cellular Structures by Finite-Memory Robots
We provide algorithmic methods for connected reconfiguration of lattice-based cellular structures by finite-state robots, motivated by large-scale constructions in space. We present algorithms that are able to...

Open AccessParticle-Based Assembly Using Precise Global Control
In micro- and nano-scale systems, particles can be moved by using an external force like gravity or a magnetic field. In the presence of adhesive particles that can attach to each other, the challenge is to de...

Open AccessCADbots: Algorithmic Aspects of Manipulating Programmable Matter with Finite Automata
We contribute results for a set of fundamental problems in the context of programmable matter by presenting algorithmic methods for evaluating and manipulating a collective of particles by a finite automaton t...

Tilt Assembly: Algorithms for Micro-factories That Build Objects with Uniform External Forces
We present algorithmic results for the parallel assembly of many micro-scale objects in two and three dimensions from tiny particles, which has been proposed in the context of programmable matter and self-asse...

Path Refinement in Weighted Regions
In this paper, we study the weighted region problem (WRP) which is to compute a shortest path in a weighted partitioning of a plane. Recent results show that WRP is not solvable in any algebraic computation mo...

Open AccessReflective practice and its role in facilitating creative responses to dilemmas within clinical communication - a qualitative analysis
Good communication is a major factor in delivering high quality in care. Research indicates that current communication skills training alone might not sufficiently enable students to find context-specific crea...

Open AccessDeterminants of physician empathy during medical education: hypothetical conclusions from an exploratory qualitative survey of practicing physicians
Empathy is an outcome-relevant physician characteristic and thus a crucial component of high-quality communication in health care. However, the factors that promote and inhibit the development of empathy durin...

Identifying and predicting subgroups of information needs among cancer patients: an initial study using latent class analysis
Understanding how the information needs of cancer patients (CaPts) vary is important because met information needs affect health outcomes and CaPts’ satisfaction. The goals of the study were to identify subgro...
