BACKGROUND The dynamic properties of microtubules depend on complex nanoscale structural rearrangements in their end regions. Members of the EB1 and XMAP215 protein families interact autonomously with microtubule ends. EB1 recruits several other proteins to growing microtubule ends and has seemingly antagonistic effects on microtubule dynamics: it induces(More)
Gustafsson (2007) discussion of our paper '4-D-Var or EnKF?' is very stimulating and brings up several interesting and valid points. We completely agree that the most useful question should be 'How can ideas from EnKF and 3–4-D-Var be best com-bined?' In the response to his comments, we point out that many of the ideas originally developed for 4-D-Var can(More)
In this paper we describe the implementation of a numerical weather forecast model on a massively parallel computer system. This model is a production code used for routine weather forecasting at the meteorological institutes of several European countries. The modiications needed to achieve a data-parallel version of this model without explicit message(More)
A data-parallel implementation on a SIMD platform of an operational numerical weather forecast model is presented. The performances of two popular numerical techniques within these models are discussed, namely finite difference (gridpoint) methods and spectral methods. In this paper in particular the performance achieved for a full production run is(More)
Despite significant progress, high-speed live-cell super-resolution studies remain limited to specialized optical setups, generally requiring intense phototoxic illumination. Here, we describe a new analytical approach, super-resolution radial fluctuations (SRRF), provided as a fast graphics processing unit-enabled ImageJ plugin. In the most challenging(More)
The results presented in this paper are part of a research project to investigate the possibilities to apply massively parallel architectures for numerical weather forecasting. Within numerical weather forecasting several numerical techniques are used to solve the model equations. This paper compares the performance of implementations on a MasPar system of(More)
A computationally intensive part in a model for numerical weather forecasting solves a set of partial diierential equations. There are several techniques to obtain this solution numerically. In this paper we will discuss the implementation of a numerical weather forecasting model on a massively parallel architecture using two techniques: a nite diierence(More)
B6rje Emilsson, Director of the Institute for Plant Research and Cold Storage (IVK), Nyn/ishamn, Sweden died suddenly on the 22nd of June 1970, at the age of fifty. In 1942 Dr. Emilsson joined the institute as a research worker, and by 1948 he had become its director. In 1948 he defended his doctoral dissertation entitled 'Studies on the Rest Period and(More)
