Synthesis and sensing of bisphosphonophosphate alkyl monoesters: A novel class of compounds for the study of nucleoside 5'-triphosphate chemistry

A series of novel β,γ-methylene-, monofluoromethylene-, and difluoromethylene-bisphosphonophosphate alkyl monoesters was synthesized. The compounds were conveniently detected during preparative HPLC using post-column derivatization with a phosphate-specific chemosensor.     

Small ternary AlnBmHl clusters: DFT analysis of structure and properties

Structural Chemistry - Using a stochastic multistep algorithm, a systematic search for the lowest energy structures and different isomeric forms of atomic AlnBmHl clusters with n + m...     

Functional equations and the Cauchy mean value theorem

The aim of this note is to characterize all pairs of sufficiently smooth functions for which the mean value in the Cauchy mean value theorem is taken at a point which has a well-determined position in the interval. As an application of this result, a partial answer is given to a question posed by Sahoo and Riedel.     

Twins in words and long common subsequences in permutations

A large family of words must contain two words that are similar. We investigate several problems where the measure of similarity is the length of a common subsequence.
