Signals of Inflationary Models with Cosmic Strings [PDF]

, 2011
A class of well-motivated models of inflation end by producing cosmic strings. The current status of efforts to calculate and observe the signals from such models are outlined, with a particular emphasis on cosmic strings, and on the Cosmic Microwave Background signal.

Energy composition of the Universe: time-independent internal symmetry

, 2005
The energy composition of the Universe, as emerged from the Type Ia supernova observations and the WMAP data, looks preposterously complex, -- but only at the first glance. In fact, its structure proves to be simple and regular.

High‐Throughput Single‐Nanowire Optoelectronic Characterization Using Microfluidic Technology

Advanced Photonics Research, EarlyView.
An ultrathin microfluidic platform enables high‐throughput, in‐line single particle characterization of semiconductor nanowires. Using correlative spectroscopy and imaging, analysis at 240 nanowires per minute, uncovering previously hidden details about intra‐wire disorder and inter‐wire inhomogeneity, is achieved.

Energy Symmetry Breaking of Dirac and Weyl Fermions in Magnetized Spinning Conical Geometries

Advanced Theory and Simulations, EarlyView.
Exact solutions for relativistic fermions in magnetized, spinning conical geometries reveal defect‐induced symmetry breaking between fermion and antifermion energies. Energy levels depend on the magnetic field, background geometry, and fractionalized spin. When the defect's spin dominates, quantum effects diminish.

Correcting for static shift of magnetotelluric data with airborne electromagnetic measurements: a case study from Rathlin Basin, Northern Ireland [PDF]

Solid Earth, 2017
Galvanic distortions of magnetotelluric (MT) data, such as the static-shift effect, are a known problem that can lead to incorrect estimation of resistivities and erroneous modelling of geometries with resulting misinterpretation of subsurface ...

Estimation of Cosmic-Ray-Induced Atmospheric Ionization and Radiation at Commercial Aviation Flight Altitudes

Applied Sciences, 2022
The main source of the ionization of the Earth’s atmosphere is the cosmic radiation that depends on solar activity as well as geomagnetic activity. Galactic cosmic rays constitute a permanent radiation background and contribute significantly to the ...
