Abstract high-performance liquid chromatography (HPLC) are including systems used for separation of explosive mixtures that despite the advantages of rapid analysis, low sample volume, and low consumption organic solvent, in use for complex matrices need to improve the selectivity and sensitivity stationary phase. One of the methods to improve selectivity and sensitivity is choosing the appr...
Upon increasing needs and vast application of neutron detectors, especially in nuclear reactors and growing number of linear accelerators, design and manufacturing of neutron detectors is a serious demand. The aim of this project is building neutron detectors capable of compensating gamma and temperature response in a radiation media. A special thermocouple coated with Boron carbide at the junc...
Inspiraling binary neutron stars are expected to be one of the most significant sources of gravitational-wave signals for the new generation of advanced ground-based detectors. We investigate how well we could hope to measure properties of these binaries using the Advanced LIGO detectors, which began operation in September 2015. We study an astrophysically motivated population of sources (binar...
Introduction Early detection of a disease outbreak using pre-diagnostic textual data is available in biosurveillance systems with the integration of data such as chief complaints. Social media has been identified as an additional pre-diagnostic data source of interest1. Textual data analysis in public health is usually based on a keyword search and often involves a complex Boolean combination o...
Context. Current generation millimeter wavelength detectors suffer from scaling limits imposed by complex cryogenic readout electronics. These instruments typically employ multiplexing ratios well below a hundred. To achieve multiplexing ratios greater than a thousand, it is imperative to investigate technologies that intrinsically incorporate strong multiplexing. One possible solution is the k...
IceCube is a kilometer scale neutrino observatory now in construction at the South Pole. The construction started in January 2005 with the deployment of 76 sensors on the first string and four surface detector stations. Nine strings and 32 surface detectors are in operation since February 2006. The data based on calibration measurements , muons and artificial light flashes are consistent with p...
Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted...

he development of technology in the THz frequency band has seen rapid progress recently. Considered as an extension of the microwave and millimeter wave bands, the THz frequency offers greater communications bandwidth than is available at microwave frequencies. The development of sources and detectors for this frequency range has been driven by other applications such as spectroscopy, imaging, ...
