The problem of the electromagnetic field created by a thin, straight conductor of infinite length carrying a forward traveling-wave current with a complex propagation constant g above a homogeneous an...
Distribution of radon activity in the atmosphere above Wzgórza Niemczansko-Strzelinskie (South-WestPoland) and its dependence on uranium and thorium content in the underlying rock and indirect ground basement
radon atmosphere uranium thorium rock
2015/9/10
Radon activity in the atmosphere and its behavior in the environment have been investigated using LR-115 nuclear
track detector. The complex geological structure of Wzgórza Niemczansko-Strzelinskie (...
Analysis of ADCP data above a bottom observatory
ADCP sensitivity current lines inclination observatory’ s wake
2015/9/7
A 300-kHz ADCP was set on GEOSTAR, a six-m3 deep-sea observatory. It was operated with cells of 80 cm during a three-week test experiment at 42-m water depth in
the northern Adriatic sub-basin. Altho...
A Gδ IDEAL OF COMPACT SETS STRICTLY ABOVE THE NOWHERE DENSE IDEAL IN THE TUKEY ORDER
Gδ IDEAL COMPACT SETS STRICTLY NOWHERE DENSE IDEAL TUKEY ORDER
2015/8/17
We prove that there is a Gδ σ-ideal of compact sets which is strictly above NWD in the Tukey order. Here NWD is the collection of all compact nowhere dense subsets of the Cantor set. This answers a qu...

The Larsen C Ice Shelf—whose neighbours Larsen A and B, collapsed in 1995 and 2002—is thinning from both its surface and beneath, according to an international study published in the journal The ...
Quantum-fluctuation effects in transport properties of superconductors above the paramagnetic limit
Quantum-fluctuation effects transport properties superconductors the paramagnetic limit
2012/2/27
We study the transport in ultrathin disordered film near the quantum critical point induced by the Zeeman field. We calculate corrections to the normal state conductivity due to quantum pairing fluctu...
Extraction of Hadron Interactions above Inelastic Threshold in Lattice QCD
nuclear potential hadron interaction lattice QCD
2011/7/21
We propose a new method to extract hadron interactions above inelastic threshold from the Nambu-Bethe-Salpter amplitude in lattice QCD.
Molecular imaging using high-order harmonic generation and above-threshold ionization
above-threshold high-order harmonic
2011/9/1
Accurate molecular imaging via high-order harmonic generation relies on comparing the harmonic emission from a molecule and an adequate reference system. However, an ideal reference atom with the same...
