\Scale-space" is an important recent concept used in image and signal processing and pattern recognition. Traditional scale-space is generated by a linear Gaus-sian smoothing operation. We present here a nonlinear type of smoother corresponding to the multiscale opening and closing operations of mathematical morphology which also generates a \scale-space." We show that a parabolic structuring e...

ABSTRACT We observed 20 Palomar–Green quasars at low redshift (z < 0.5) with total flux density >1 mJy, including four radio-loud (RLQs) and 16 radio-quiet (RQQs), using the Very Long Baseline Array (VLBA) 5 GHz. 10 RQQs are clearly detected in VLBA images, a compact radio core is identified eight of them, indicating prevalence active galactic nucleus (AGN)-related emission this f...

Heterotrophic chrysomonads of the genus Paraphysomonas are ubiquitous phagotrophs with diverse silica scale morphology. Over 50 named species have been described by electron microscopy from uncultured environmental samples. Sequence data exist for very few, but the literature reveals misidentification or lumping of most previously sequenced. For critically integrating scale and sequence data, 5...

We present a unified picture on the evolution of galaxy luminosity and morphology. Galaxy morphology is found to depend critically on the local environment set up by the nearest neighbor galaxy in addition to luminosity and the large scale density. When a galaxy is located farther than the virial radius from its closest neighbor, the probability for the galaxy to have an early morphological typ...

In this study, otolith morphology and otolith contour from big-scale sand smelt, Atherina boyeri were analyzed in Lake Eğirdir and Lake İznik (natural lakes), and Hirfanlı Dam Lake (artificial lake). The otolith contour and sixteen otolith morphological characters such as width, depth, shape, sulcus acusticus shape, ostium, cauda, rostrum size-shape, and thickness, antirostrum size-shape, and t...
