Escherichia coli MRE 600 is a colicinogenic bacterium. Its colicinogenic activity may be ascribed mostly to colicin E1, although it produces a small amount of another, as yet unidentified, colicin.

An international network of laser-interferometric gravitational wave detectors is nearing the end of the main commissioning phase and will soon enter into an extended observational period, collecting data for a duration of order one year. This article outlines the construction, design and commissioning of the GEO 600 gravitational wave observatory. GEO 600 is a laserinterferometric gravitationa...

Though many techniques for finding malicious code have been developed, we found few publicized techniques for creating and hiding malicious code. Traditional malicious code examples include viruses, trojans, and worms, but we define malicious code to be any code that does not behave as the user intended. Our goal is to analyze current methods for the creation and hiding of malicious code and to...

The fossil record of fungi and lichens is scarce. Here we report the discovery of lichen-like fossils, involving filamentous hyphae closely associated with coccoidal cyanobacteria or algae, preserved in marine phosphorite of the Doushantuo Formation (between 551 and 635 million years old) at Weng'an, South China. These fossils indicate that fungi developed symbiotic partnerships with photoautot...

The chiral symmetry and the notion of its dynamical breaking have been playing a central role in understanding the spectroscopy of hadrons with light-quarks. Presently the non-linear representation (Non-Linear σ Model(NLσM)) of chiral SU(2)L×SU(2)R group is widely accepted to be realized in nature on the basis of the success of low energy theorems concerning π mesons as Nambu-Goldstone bosons. ...

We have studied the µ decay energy spectrum from a sample of stopping µ events acquired during the test run of the ICARUS T600 prototype. This detector allows the spatial reconstruction of the events with fine granularity, hence the precise measurement of the µ range and dE/dx with high sampling rate. This information is used to compute the correction factors needed for the calorimetric reconst...
