the normal and lateral line cycloid scales of a cyprinid fish; alburnoides bipunctatus (blotch, 1782) have been subjected to sem to study their detailed structure. it shows the general architectural pattern of a cycloid cyprinid scale. the focus of the scale is clear and sharp located in the anterior field. circuli are observed in all fields. primary radii which originate from very near the foc...

the normal and lateral line cycloid scales of the native species garra rossica (nikol’skii, 1900), one of the most common and poorly known cyprinid fish in south-eastern iran have been subjected to the scanning electron microscopy technique in order to study their detailed structure. normal scale below the dorsal fin showed a clearcut demonstration between the anterior and posterior region with...

Real networks have in common that they evolve over time and their dynamics have a huge impact on their structure. Clustering is an efficient tool to reduce the complexity to allow representation of the data. In 2014, Eisenstat et al. introduced a dynamic version of this classic problem where the distances evolve with time and where coherence over time is enforced by introducing a cost for clien...

In this note we present inequalities relating the successive minima of a o-symmetric convex body and the successive inner and outer radii of the body. These inequalities build a bridge between known inequalities involving only either the successive minima or the successive radii.
