sectionHarmonic Volumetric Parameterization using MFS After the decomposition of a given object M , we get a set of star shapes {Mi}, each region being guarded by a point gi. Then we can parameterize each subregion onto a solid sphere. A key property that we will show shortly is that such a harmonic map is guaranteed to be bijective. The harmonic map can be computed using the method of fundamen...

STAR collected data in proton-proton collisions at √ s = 200 GeV with transverse and longitudinal beam polarizations during the initial running periods in 2002–2004 at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Results on the single transverse spin asymmetries in the production of high energy forward neutral pions and of forward charged hadrons will be presented. Dat...

Context. The evolution of quasar host galaxies is still hardly studied at high redshifts (z > 2), although this is a very interesting redshift range as both the quasar activity and the star formation rate density have their peak at z ≈ 2–3. This makes is especially interesting to study properties of quasar host galaxies, such as the star formation rate or the black hole mass at this redshift. A...

A novel hierarchical star-like Co(3)O(4) was successfully synthesized from self-assembled hierarchical Co(OH)F precursors via a facile hydrothermal method and subsequent annealing in air. The morphological evolution process of the Co(OH)F precursors was investigated by examining the different reaction times during synthesis. First, hexagonal plates are formed, and then nanodiscs grow on the sur...

EUVE satellite spectroscopic observations (SW, MW and LW bands covering 80 – 160, 170 – 350 and 450 Å with resolutions 0.5, 1 and 2 Å) and photometric observations (Deep Sky Survey, broad-band 70 – 140 Å) have been obtained for two contact, 44i Boo B and VW Cep, and one detached, ER Vul, close binary stars. All three systems have orbital periods shorter than one day and thus are expected to sho...

We address the problem of resolving and localizing blurred point sources in intensity images. Telescopic star-field images blurred by atmospheric turbulence or optical aberrations are typical examples of this class of images, a new approach to image restoration is introduced, which is a generalization of 2-D sensor array processing techniques originating from the field of direction of arrival e...

in this paper some new applications of empirical mode decomposition (emd) and hilbert spectrum in seismic ground-roll attenuation, random noise attenuation and spectral decomposition are introduced. hilbert spectrum is a time-frequency representation for hilbert-huang transform which is obtained by combination of instantaneous frequency (if) concept and intrinsic mode function of empirical mode...

We present the CO(1-0) and CO(2-1) line maps obtained observing with the SEST a ∼ 1 × 1 region of the Vela Molecular Ridge, Cloud D. This cloud is part of an intermediate-mass star forming region that is relatively close to the Sun. Our observations reveal, over a wide range of spatial scales (from ∼ 0.1 to a few parsecs), a variety of dense structures such as arcs, filaments and clumps, that a...

To address how the galaxy Hubble sequence is established and what physical processes are involved, we studied morphological properties and internal structures of field galaxies in the past (0.4 < z < 1). In addition to structural parameters derived from bulge+disk decomposition, Zheng et al. (2004) introduced color maps in recognizing galaxies and properly classified morphologies of 36 luminous...

We present the derivation of the perturbation equations governing the oscillations of relativistic nonrotating neutron star models using the (3+1)-decomposition. We show that the perturbation equations can always be written in terms of spacetime variables only, regardless of any particular gauge. We demonstrate how to obtain the Regge-Wheeler gauge, by choosing appropriate shift and lapse. In a...
