The Generalized Fibonacci Numbers {Cn}, Cn = Cn-1 + Cn-2 + K
1988There are many ways to generalize the well-known Fibonacci sequence {Fn}, Fn = Fn-1 + Fn-2, F1 = 1, F2 = 1. In a personal letter dated December 18, 1985, Frank Harary asked one of the authors if they had ever encountered Cn = Cn-1 + Cn-2 + 1, which was used by Harary in connection with something he was counting involving Boolean Algebras.

We address the issue of the learnability of concept classes under three classification noise models in the probably approximately correct framework. After introducing the Class-Conditional Classification Noise (CCCN) model, we investigate the problem of the learnability of concept classes under this particular setting and we show that concept classes ...

Central nervous system vasculitis (CNSV) is a complex disease that poses considerable diagnostic and therapeutic challenges. It is divided into primary angiitis of the CNS (PACNS), or secondary angiitis of the CNS when associated with systemic conditions. Clinical presentation can be extremely variable and there is no classic presentation. In addition,

CN− bond length in e+CN−: contrast with H+CN−
Chemical Physics Letters, 1999Abstract The CN − bond length in e + CN − was determined by positron annihilation. The obtained value (0.192 nm) was compared with those of CN − in HCN (or H + CN − ) (0.116 nm) and in MCN (M + =Na + , K + , Rb + , Cs + , Tl + ) (ca. 0.190 nm). This finding supports the statement, already advanced, based on the rate constants of Ps (positronium)

Vasculitis of the central nervous system can be of several varieties depending upon the vessel(s) involved and type of disorder. One can see primary CNS vasculitis as a distinct entity which is primarily manifested as central nervous system injury in a vascular distribution or the vasculitic process can be secondary to a systemic disorder such as ...

CNS Involvement in HLH (CNS-HLH)
2017CNS disease is considered to be a result of the pathologic immune response in HLH. CNS involvement is frequently found at diagnosis or can occur anytime in the further course of systemic HLH but has also been reported as primary or only manifestation.
