Monitoring Variability of the Sky Bohdan
Variability in the sky has been known for centuries, even millennia, but our knowledge of it is very incomplete even at the bright end. Current technology makes it possible to built small, robotic optical instruments, to record images and to process data in real time, and to archive them on-line, all at a low cost. In addition to obtaining complete catalogs of all kinds of variable objects, spe...
متن کاملBohdan’s Impact on Our Understanding of Gamma-ray Bursts
Bohdan Paczyński was one of the pioneers of the cosmological GRB model. His ideas on how GRBs operate and what are their progenitors have dominated the field of GRBs in the hectic nineties during which the distances and the origin of GRBs were revealed. I discuss here Bohdan’s contributions in some historical perspective.

REPEATED reports from Japan and from north European countries have brought attention to a new clinical syndrome called "pulseless, or Takayasu disease." The condition is found in young women and is characterized by thrombosis of the vessels deriving from the arch of the aorta associated with cerebral, ocular, and upper extremity symptoms. Its etiology is obscure. We are presenting a case of thi...
متن کاملBohdan Zelinka INDEPENDENT SET DOMINATING SETS IN BIPARTITE GRAPHS
The paper continues the study of independent set dominating sets in graphs which was started by E. Sampathkumar. A subset D of the vertex set V (G) of a graph G is called a set dominating set (shortly sd−set) in G, if for each set X ⊆ V (G) −D there exists a set Y ⊆ D such that the subgraph 〈X ∪ Y 〉 of G induced by X ∪ Y is connected. The minimum number of vertices of an sd−set in G is called t...
