Brucella “Hitches a Ride” with Autophagy

Dancing with your ride

The technologies that make this possible are those of miniaturized electronics, digital communications, inexpensive distributed computation, and advanced control software. They enable us to get rid of most of the junk that currently encumbers automobiles – engines, power trains, dashboards, and steering wheels. They allow us to define a fundamentally new, radically restructured architecture for...

Taxi and Ride Sharing: A Dynamic Dial-a-Ride Problem with Money as an Incentive

This paper deals with a combinatorial optimization problem that models situations of both dynamic ridesharing and taxi-sharing. Passengers who want to share a taxi or a ride, use an app to specify their current location, destination and further information such as the earliest departure time, the latest arrival time and the maximum cost they are willing to pay for the ride. Car owners also spec...

The Dial-A-Ride Problem with Transfers

The Dial–A–Ride Problem with Transfers (DARPT) consists in defining a set of routes that satisfy transportation requests of users between a set of pickup points and a set of delivery points, in the presence of ride time constraints. Users may change vehicles during their trip. This change of vehicle, called a transfer, is made at specific locations called transfer points. Solving the DARPT invo...

A fat ride

JCB • VOLUME 169 • NUMBER 4 • 2005 550 A fat ride he Wingless (Wg) and Hedgehog (Hh) morphogens spread beween cells by catching a ride on lipoprotein particles, say Daniela Panáková, Hein Sprong, Christoph Thiele, Suzanne Eaton, and colleagues (Max Planck, Dresden, Germany). The group had earlier spotted unidentified intercellular signaling particles that they dubbed argosomes. Argosomes are no...
