Irreversible broadening of spectral holes in chlorin-doped polystyrene glass was studied for the first time in the temperature cycling experiments
Triple-layered ruthenate Sr$_4$Ru$_3$O$_{10}$ shows a first-order itinerant metamagnetic transition for in-plane magnetic fields. Our experiments revealed rather surprising behavior in
The Josephson quasiparticle (JQP) cycle in a voltage-biased superconducting single-electron transistor (SSET) combines coherent Cooper pair tunneling with incoherent quasiparticle
This thesis starts with a review of BPS M-branes and their supergravity solutions. These solutions can be obtained in various
We present a study of the intraday variability behaviour of two samples of x-ray selected BL Lac objects, the EMSS
Whereas a variation of the solar luminosity, L, will inevitably cause a similar change of the total solar irradiance, S,
Andersson et al. and Bildsten proposed that the spin of accreting neutron stars is limited by removal of angular momentum
We study M-theory fivebranes wrapped on Special Lagrangian submanifolds ($§_n$) in Calabi-Yau three- and fourfolds. When the M5 wraps a
The following optimization problem was introduced in \cite{gutinDAM}, where it was motivated by a real-world problem in defence logistics. Suppose
The structure of the surface layers of the Sun is changed by magnetic activity which, in turn, changes the eigenfrequencies
We study the accretion efficiency of neutron stars in long-period binaries, i.e. with periods longer than about 200d, which accrete
We report new determinations of the radius and mass of the pulsating helium-rich, hydrogen-deficient star LSS 3184 (BX Cir) using
We present an analysis of new spectroscopic observations of the bright Be star kappa Dra obtained at the Ondrejov observatory
We formulate a renormalization group (RG) for the interaction parameters of the general two-body problem and show how a limit
We introduce a dynamic light scattering technique capable of resolving motion that changes systematically, and rapidly, with time. It is
Supergravity solution describing two intersecting M5-branes is presented. The branes are fixed in the relative transverse directions and are delocalized
Temperature cycling is used to study of aging properties of PMMA dielectric constant. If a negative temperature cycle is applied
We have analysed temporal evolution in centroid frequencies and splitting coefficients of solar f-modes obtained from MDI/SOHO. The data were
We report on the analysis of the ASCA and BeppoSAX X-ray observations of the polar system BL Hyi. Emission from
We present results of our analysis of a set of RXTE/PCA observations of X-ray flares/bursts with burst cycle ranging from
In this paper we present an extremely simple structure solution method termed charge flipping. It works ab initio on high
There are several ways to generalize characteristic classes for singular algebraic varieties. The simplest ones to describe are Chern-Mather classes
Cosmology is investigated within a new, scalar theory of gravitation, which is a preferred-frame bimetric theory with flat background metric.
I review recent advances in our understanding of accretion disks in transient systems - the dwarf novae and the soft
