Operating micro aerial vehicles (MAVs) outside of the bounds of a rigidly controlled lab environment, specifically one that is unstructured and contains unknown obstacles, poses a number of challenges. One of these challenges is that of quickly determining an optimal (or nearly so) path from the MAVs current position to a designated goal state. Past work in(More)
INTRODUCTION This article illustrates a new treatment approach and evaluates the effect of use of fluoridated toothpaste on the remineralization of white spot lesions (WSLs) diagnosed at debonding. MATERIALS AND METHODS Thirty-one orthodontic patients (mean age: 19.6 years), with a minimum of four WSLs on the buccal surfaces of the maxillary and(More)
INTRODUCTION The cranial base plays a key role in craniofacial growth; it helps to integrate spatially and functionally different patterns of growth in various adjoining regions of the skull such as components of the brain, the nasal and oral cavity and the pharynx. The aim of this study was to evaluate the difference in cranial base flexure between(More)
The electrophoretic mobility of molecules such as λ-DNA depends on the conformation of the molecule. It has been shown that electrohydrodynamic interactions between parts of the molecule lead to a mobility that depends on conformation and can explain some experimental observations. We have developed a new coarse-grained model that incorporates these changes(More)
We present computer simulations of a rigid rod in a combination of an extensional fluid flow and extensional electric field. The electrophoretic mobility of the rod is different parallel or perpendicular to the rod. The dependence of the mobility on the conformation (orientation) leads to a new phenomenon where the rods can be passively trapped in all(More)
