We present StreamMapReduce, a data processing approach that combines ideas from the popular MapReduce paradigm and recent developments in Event Stream Processing. We adopted the simple and scalable programming model of MapReduce and added continuous, low-latency data processing capabilities previously found only in Event Stream Processing systems. This(More)
The wealth of information existing on the general principle of S-layers has revealed a broad application potential. The most relevant features exploited in applied S-layer research are: (i) pores passing through S-layers show identical size and morphology and are in the range of ultrafiltration membranes; (ii) functional groups on the surface and in the(More)
A new approach to play games quantum mechanically is proposed. We consider two players who perform measurements in an EPR-type setting. The payoff relations are defined as functions of correlations, i.e. without reference to classical or quantum mechanics. Classical bi-matrix games are reproduced if the input states are classical and perfectly(More)
By routing messages based on their content, publish/subscribe (pub/sub) systems remove the need to establish and maintain fixed communication channels. Pub/sub is a natural candidate for designing large-scale systems, composed of applications running in different domains and communicating via middleware solutions deployed on a public cloud. Such pub/sub(More)
Arbitrary faults such as bit flips have been often observed in commodity-hardware data centers and have disrupted large services. Benign faults, such as crashes and message omissions, are nevertheless the standard assumption in practical fault-tolerant distributed systems. Algorithms tolerant to arbitrary faults are harder to understand and more expensive(More)
In the present study, the applicability of crystalline bacterial cell-surface layers (S-layers) as novel immobilization matrices and reaction zones for dipstick-style immunoassays was investigated. For this purpose, S-layer-carrying cell-wall fragments from Bacillus sphaericus CCM 2120 were deposited on a microporous support, and the S-layer protein was(More)
Analyzing huge amounts of log data is often a difficult task, especially if it has to be done in real time (e.g., fraud detection) or when large amounts of stored data are required for the analysis. Graphs are a data structure often used in log analysis. Examples are clique analysis and communities of interest (COI). However, little attention has been paid(More)
The S-layer protein SbpA of Bacillus sphaericus CCM 2177 recognizes a pyruvylated secondary cell wall polymer (SCWP) as anchoring structure to the peptidoglycan-containing layer. Data analysis from surface plasmon resonance (SPR) spectroscopy revealed the existence of three different binding sites with high, medium and low affinity for rSbpA on SCWP(More)
The bacterial cell surface layer (S-layer) protein of Bacillus sphaericus CCM 2177 assembles into a square lattice structure and recognizes a distinct type of secondary cell wall polymer (SCWP) as the proper anchoring structure in the rigid cell wall layer. For generating a nanopatterned sensing layer with high density and well defined distance of the(More)
Crystalline bacterial cell surface layer (S-layer) proteins are composed of a single protein or glycoprotein species. Isolated S-layer subunits frequently recrystallize into monomolecular protein lattices on various types of solid supports. For generating a functional protein lattice, a chimeric protein was constructed, which comprised the secondary cell(More)
