We report the results of the spatial and spectral analysis of the ROSAT HRI and PSPC observations of the edge-on spiral galaxy NGC 3079. We detected several sources in the field of NGC 3079 with both PSPC and HRI, and complex emission from the inner 5′ around NGC 3079. We have identified possible counterparts for several of the sources outside NGC 3079 by comparison with optical plates and cata...

We pursue the analysis of the Schrödinger operator on the unit interval in inverse spectral theory initiated in [AR]. Whereas the potentials in [AR] belong to L with their difference in L (1 ≤ p < ∞) we consider here potentials in W k,1 spaces having their difference in W k,p where 1 ≤ p ≤ +∞, k ∈ {0, 1, 2}. It is proved that two potentials in W ([0, 1]) being equal on [a, 1] are also equal on ...

Tartrate-resistant acid phosphatase (TRAP) plays an important role in bone resorption. TRAP expression in osteoclasts is regulated by receptor activator of NF-kappaB (RANKL), a potent activator of osteoclast differentiation. However, the molecular mechanism underlying the RANKL-induced TRAP expression remains unknown. Here we show that two regions in the mouse TRAP promoter (one at -1858 to -12...

While many observed ultra-luminous X-ray sources (ULXs, LX ≥ 1039 erg s−1) could be extragalactic X-ray binaries (XRBs) emitting close to the Eddington limit, the highest-luminosity ULXs (LX > 3× 1039 erg s−1) exceed the isotropic Eddington luminosity for even high-stellar-mass accreting black hole XRBs. It has been suggested that these highest-luminosity ULXs may contain accreting intermediate...
