A sample of 32 galaxies with accurate distance moduli from the Cepheid PL-relation (Lanoix 1999) has been used to study
We analyse a sample of 236 Cepheids from the Hipparcos catalog, using the method of ``reduced parallaxes'' in V, I,
The Cepheids' P-L relation got itself talked about again in the recent past due to claims of observed metallicity dependences
Using micro- and nano-scale resonantly excited PL and PLE, we study the excitonic structure of CdSe/ZnSe and CdTe/ZnTe self assembled
Photoluminescence (PL) and photoluminescence excitation (PLE) spectroscopy of pillar-suspended single-walled carbon nanotubes has been measured for temperatures between 300 K
The period-luminosity (PL) relation for Galactic Cepheids is derived with recent independent distance measurements taken from literature. Our PL relation
It is considered gravitational interaction within the framework of the Newton theory and the quantum field theory. It is introduced
Susceptibility of scale free Power Law (PL) networks to attacks has been traditionally studied in the context of what may
A recent single quantum wire is of sufficient quality to reveal new details of the photoluminescence (PL) evolution with increasing
We show that a realization of a closed connected PL-manifold of dimension n-1 in n-dimensional Euclidean space (n>2) is the
(Abridged) I cross-correlate the OGLE database of Cepheids in the Large and Small Magellanic Clouds (MCs) with the second incremental
This is an investigation of the period-luminosity relation of classical Cepheids in samples of different metallicity. It is based on
Theories in which neutrino masses are generated by a conventional see-saw mechanism generically yield masses which are O(v^2) in units
By direct absorption spectroscopy and comparison to photoluminescence (PL), we investigate negatively charged excitons in dilute two-dimensional electron systems at
We present an experimental investigation of heavy doping-induced many-body effects such as band gap narrowing(BGN) and Fermi edge singularity(FES) in
Self-assembly of structurally tunned nearly monodispersed HgTe - ssDNA nanostars of average size 1.4 nm have been achieved by manipulating
The infrared attractiveness of soft-supersymmetry breaking (SSB) parameters is investigated in extra dimensions. The SSB parameters are assumed to run
A cosmology with a dynamical Planck mass $m_{pl}$ is shown to solve the horizon and monopole problems (and possibly flatness)
We present results of the search for Cepheids in the galaxy IC1613 carried out as a sub-project of the OGLE-II
We used the OGLE-II and OGLE-III photometry of red giants in the Large Magellanic Cloud to select and study objects
This study toward quantum gravity (QG) introduces an SU(N) gauge theory with the Θvacuum term as a trial theory. Newton
The light curves of Cepheids and other variable stars in Field A of IC 1613, obtained with a CCD and
We introduce a graphical representation for a global SO(n) tensor $\pl_\m\pl_\n h_\ab$, which generally appears in the perturbative approach of
The statistical test described by Wielen et al.(1994) is used to derive new zero-points of ground-based Cepheid period-luminosity (PL) and
