Period fissioning and other instabilities of stressed elastic membranes
Under elastic membrane the shape of stretching two dimensional parameter space
2014/12/19
We study the shapes of elastic membranes under the simultaneous exertion of tensile and compressive forces when the translational symmetry along the tension direction is broken. We predict a multitude...
We present a simple algorithm to locate the onset and bifurcation points of period-n cycles of the logistic map and some related maps. For the logistic, H\'enon and cubic map, we computed the polynomi...
Electronic correlations in short period (CrAs)$_n$/(GaAs)$_n$ ferromagnetic heterostructures
Electronic correlations ferromagnetic heterostructures
2010/11/24
We investigate half-metallicity in [001] stacked (CrAs)n/(GaAs)n heterostructures with n ≤ 3
by means of a combined many-body and electronic structure calculation. Interface states in the
presence o...
Source Mechanism of Long Period events recorded by a high density seismic network during the 2008 eruption on Mt Etna
Source Mechanism high density seismic network the 2008 eruption on Mt Etna
2010/11/16
129 Long Period (LP) events, divided into two families of similar events, were recorded by the 50 stations deployed on Mount Etna in the second half of June 2008. During this period lava was flowing ...
Operation and calibration of the Silicon Drift Detectors of the ALICE experiment during the 2008 cosmic ray data taking period
Trackong detectors silicon detectors LHC
2010/3/15
The calibration and performance of the Silicon Drift Detector of the ALICE experiment during the 2008 cosmic ray run will be presented. In particular the procedures to monitor the running parameters (...
Quantum and Classical Dynamics of a BEC in a Large-Period Optical Lattice
Quantum and Classical Dynamics BEC Large-Period Optical Lattice
2010/4/8
We experimentally investigate diffraction of a Rb-87 Bose-Einstein condensate from a 1D optical lattice. We use a range of lattice periods and timescales, including those beyond the Raman-Nath limit. ...

Multiple Period Search for K, M and C Type Semiregular Variables in TÜBİTAK National Observatory
stars variable stars late-type stars photometry stars period
2010/4/9
In this study, periods obtained from long-term multi-bands (Johnson V and R filters) photometric observations of some K, M and C spectral type semiregular (SR) variables obtained with the T40 telescop...
Comparative Study of First Two Harmonics in Cosmic Ray Intensity for the Period 1964-95
Cosmic rays Diurnal Semi-diurnal Anisotropy and Solar poloidal magnetic field
2010/4/12
The Deep River neutron monitor data has been harmonically analyzed for the period 1964--95 covering three solar cycles 20, 21 and 22, looking for a long term trend of the diurnal and semi-diurnal anis...
Orbital Period Modulation in Chromospherically Active Close Binaries
Orbital Period Modulation Chromospherically Active Close Binaries
2010/4/16
The orbital period changes in some chromospherically active close binaries have been interpreted as a consequence of magnetic activity. At least in two active close binaries a possible relationship be...
Short-period RS CVn and W UMa binaries: how are they related?
W Ursae Majoris angular momentum loss
2010/4/16
Two groups of late-type very close main sequence binaries, the so-called short-period RS Canum Venaticorum (RS CVn) and W Ursae Majoris (W UMa) systems, are important for the understanding of the stru...

2010/4/16
The long-term period variations of the classical algol-type binaries XZ And, U Cep, b Per, RT Per, ST Per and TX UMa were studied by using all available observed times of eclipse minima. The (O-C) dia...
