Hodgkiss, W. (Torry Research Station, Aberdeen, Scotland), and Z. John Ordal. Morphology of the spore of some strains of Clostridium botulinum type E. J. Bacteriol. 91:2031-2036. 1966.-The spores of four strains of C. botulinum type E show an unusual and elaborate morphology. Numerous tubular appendages radiate from the surface of the spore. The spore and its appendages are enclosed in a delica...

High availability is the desirable feature of the data in a data grid. The data is replicated in a data grid to increase the data availability, reliability and improve the response time of the applications by reducing the network traffic. The efficiency and fast access to such replicated data are influenced by the location of the resource holding the replica and the access cost. The replica loc...

Data grid replication is critical for improving the performance of data intensive applications. Most of the used techniques for data replication use Replica Location Services (RLS) to resolve the logical name of files to its physical locations. An example of such service is Giggle, which can be found in the OGSA/Globus architecture. Classical algorithms also need some catalog and optimization s...

More and more applications emphasize analysis huge data and depend on the data transmission. Data Grids enable the selection, sharing, and connection of a wide variety of geographically distributed computational and storage resources for content the large-scale data-intensive application needs. Data grids consist of scattered computing and storage resources located in different countries/region...

Efficient embedding virtual clusters in physical network is a challenging problem. In this paper we consider a scenario where physical network has a structure of a balanced tree. This assumption is justified by many realworld implementations of datacenters. We consider an extension to virtual cluster embedding by introducing replication among data chunks. In many real-world applications, data i...

Todays standard molecular dynamics (MD) simulations of moderately sized biomolecular systems at full atomic resolution are typically limited to the nanosecond timescale and therefore suffer from limited conformational sampling. Efficient ensemble-preserving algorithms like replica exchange (REX) may alleviate this problem somewhat but are still computationally prohibitive due to the large numbe...

Abstract The application of a deformable grating to the realization time delay compensated monochromator is presented. realized as replica on thin glass substrate and deformation with mechanical bender. conceived for spectral selection single harmonic in range 20-80 nm beamlines exploiting high generation process. A possible optical design requiring only two gratings, mirror an intermediate slit

Random lasers are optical sources where light is amplified by stimulated emission along random paths through an amplifying scattering medium. Connections between their physics and the one of quenched disordered nonlinear systems, notably spin glasses, have been recently suggested. Here we report a first experimental study of correlations of spectral fluctuations intensity in a random laser medi...

Internet of Things (IoT) has lately been presented as a new technological transformation in which things are connected via the Internet. Several sensors and devices create data send vital signals constantly over sophisticated networks that allow machine-to-machine interactions monitor manage key smart-world infrastructures. Since huge amounts generated, reducing access costs is critical issue. ...

Today, data grids have become an important emerging platform for managing and processing a very large amount of data distributed across multiple grid nodes and stored in relational databases. However, there are still obstacles for potential grid users to be involved into the trend and the data grid application development is far from the data grids. While the traditional established data grid a...
