Abstract As spherical shell mantle convection models become increasingly commonplace, understanding how plates are generated has raised the issue of how to recognize whether rigid plates are present in model output. Tectonocists have long recognized that intraplate regions are not rigid without exception.

Paenarthrobacter are specialists in degrading the fungicide iprodione. We showed that this trait has evolved through gene duplication of ipaH and ddaH genes, being in the core genome of paenarthrobacters, and further genetic optimisation, with different strains being at different evolution stages depending on their prior exposure to iprodione ...

Healthcare queueing models. [PDF]
Healthcare systems differ intrinsically from manufacturing systems. As such, they require a distinct modeling approach. In this article, we show how to construct a queueing model of a general class of healthcare systems.

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

A tight bound on the throughput of queueing networks with blocking [PDF]
In this paper, we present a bounding methodology that allows to compute a tight lower bound on the cycle time of fork--join queueing networks with blocking and with general service time distributions. The methodology relies on two ideas.

The TanDEM-X Mission: Overview and Status [PDF]
TanDEM-X opens a new era in space borne radar remote sensing. The first bistatic SAR mission, is formed by adding a second, almost identical spacecraft, to TerraSARX and flying the two satellites in a closely controlled formation with typical ...

On closed queueing networks with mixed preemptive resume priority servers. [PDF]
This paper discusses a typical closed queueing network model in which multiple preemptive resume servers are present with different priority structures at each priority node. An algorithm is developed that is applicable for the three-node two-class model

Network of Tandem and Bi-Tandem Queueing Process with Reneging and Jockeying
The steady state behaviour of a queueing model where two bi-tandem channels are linked in tandem with a common channel has been studied using the concept of reneging and ...

Analyzing a Tandem Fluid Queueing Model with Stochastic Capacity and Spillback
The tandem fluid queueing model is a useful tool for performance analysis and control design for a variety of transportation systems. In this article, we study the joint impact of stochastic capacity and spillback on the long-time properties of this model. Our analysis focuses on the system of two fluid queueing links in series. The upstream link has a
