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.

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)

[Te(CN)4] versus [Te(CN)3(µ-CN)]n
Dalton Transactions, 2008Solvent molecules have a great influence on the structure and stability of tellurium tetracyanide; whereas Te(CN)4·(diglyme)2 1a contains monomeric Te(CN)4 units, [Te(CN)3(µ-CN)·diglyme]n1b is a coordination polymer.

Frontiers in Bioscience, 2004
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 ...

[Te(CN)4] versus [Te(CN)3(micro-CN)](n).
Dalton transactions (Cambridge, England : 2003), 2008Solvent molecules have a great influence on the structure and stability of tellurium tetracyanide; whereas Te(CN)4 x (diglyme)(2) contains monomeric Te(CN)4 units, [Te(CN)3(micro-CN) x diglyme](n) is a coordination polymer.

Nachweis von Cl′ neben CN′, [Fe(CN)6]′″ [Fe(CN)6]″″ und CNS′
1926Theorie der Trennung: Aus dem Sauregemisch werden durch Cu.. alle Sauren des Cyans und Rhodanwasserstoff als die entsprechenden Kupfersalze ausgefallt. Cl′ bleibt als Kupfer(2)chlorid in Losung und kann, nach dem Wegkochen des nach $$2Cu{(CN)_2} = 2CuCN + {(CN)_2}$$ frei werdenden Cyans in der Losung nachgewiesen werden.

Current Opinion in Ophthalmology, 2015
Despite recent progress, the diagnosis of primary CNS lymphoma (PCNSL) remains a challenge and is often delayed by several months. Treatment options are still debated and the prognosis of PCNSL lymphoma is poor for most patients. This review will describe recent progress and future orientations for diagnosis of PCNSL and report on the recent trends ...

Best Practice & Research Clinical Haematology, 2012
Primary CNS lymphoma (PCNSL) is a rare and aggressive brain tumor with an unsatisfactory outcome. Therapeutic progress in this field is strongly conditioned by the limited biology and the molecular knowledge about this disease, which hamperizes the identification of new targeted therapies and the poor clinical conditions and performance status of ...

The process of modeling reactive distributed systems by a component Petri net is considered. The mechanism of constructing of composite components (places and transitions) of a CN-net is shown. A CN net is analyzed by modeling, as an example, a railroad traffic pattern at a railroad junction.
