background: neonates affected by hereditary spherocytosis may suffer from significant jaundice. this study was conducted on neonates with jaundice hospitalized at the children’s hospital in bandar abbas, south iran, to determine the frequency of hereditary spherocytosis among them. patients and methods: in this cross-sectional study, 814 neonates with jaundice hospitalized at the children’s hos...

If C is a subclass of the class of claw-free graphs, then C is said to be stable if, for any G ∈ C, the local completion of G at any vertex is also in C. If cl is a closure operation that turns a claw-free graph into a line graph by a series of local completions and C is stable, then cl(G) ∈ C for any G ∈ C. In the talk we consider stability of hereditary classes of claw-free graphs defined in ...

Evolution and development are both lineage processes but are often conceptualized as occurring by different and mutually exclusive mechanisms. It is conventionally asserted that evolution occurs via the random generation of diversity and the subsequent survival of those that pass selection. On the other hand, development is too often presented as proceeding via the unfolding of a deterministic ...

In this paper‎, ‎we study the class of rings in which every $P$-flat‎ ‎ideal is flat and which will be called $PFF$-rings‎. ‎In particular‎, ‎Von Neumann regular rings‎, ‎hereditary rings‎, ‎semi-hereditary ring‎, ‎PID and arithmetical rings are examples of $PFF$-rings‎. ‎In the context domain‎, ‎this notion coincide with‎ ‎Pr"{u}fer domain‎. ‎We provide necessary and sufficient conditions for‎...

the hereditary ataxias comprise a wide spectrum of heterogeneous disorders that share three features: ataxia, involvement of cerebellum or its connections, and heritability. in many hereditary ataxias, the underlying gene mutations have been identified. knowledge of the causative mutations allows a rational classification of hereditary ataxias as autosomal recessive, autosomal dominant or mater...
