The Tunka Radio Extension (Tunka-Rex): Status and First Results

Status and first results of Tunka-Rex, an experiment for the radio detection of air showers

Tunka-Rex is a new radio detector for extensive air showers from cosmic rays, built in 2012 as an extension to Tunka133. The latter is a non-imaging air-Cherenkov detector, located near Lake Baikal, Siberia. With its 25 radio antennas, Tunka-Rex extends over an area of 1 km2 with a spacing of 200 m and therefore is expected to be sensitive to an primary energy range of approximately 1017-1018 e...

A comparison of the cosmic-ray energy scales of Tunka-133 and KASCADE-Grande via their radio extensions Tunka-Rex and LOPES

An investigation of using hump in the Cherenkov photon lateral distribution for Gamma-Hadron separation

Simulation of gamma and hadron showers in the energy range 100GeV- 25TeV has been carried out. For a big ideal Cherenkov light array, characteristics of lateral distribution of Cherenkov photon density have been studied. Results from this ideal detector are compared with those simulated for a real TUNKA- like array to investigate experimental potential of using existence of a hump in lateral di...

Ruby Benchmark Suite using Docker

The purpose of this paper is to introduce and describe a new Ruby benchmarking tool. We will describe the background of Ruby benchmarking and the advantages of the new tool. The paper documents the benchmarking process as well as methods used to obtain results and run tests. To illustrate the provided tool, results that were obtained by running a developed benchmarking tool on existing and avai...

Evaluation of direct antiviral activity of the Deva-5 herb formulation and extracts of five Asian plants against influenza A virus H3N8

BACKGROUND The herb formulation Deva-5 is used in traditional medicine to treat acute infectious diseases. Deva-5 is composed of five herbs: Gentiana decumbens L., Momordica cochinchinensis L., Hypecoum erectum L., Polygonum bistorta L., and Terminalia chebula Retz. Deva-5 and its five components were investigated for in vitro antiviral activity against avian influenza A virus subtype H3N8. M...
