We investigate behavior of the Fisher information matrix of general stable distributions. Du-Mouchel (1975, 1983) proved that the Fisher information I αα of characteristic exponent α diverges to infinity as α approaches 2. Nagaev and Shkol'nik (1988) made more detailed analysis of I αα and derived asymptotic behavior of I αα diverging to infinity as α approaches 2 in the symmetric case. Extendi...
The hydrochloride of the racemic amino acid (7-hydroxycoumarin-4-yl)ethylglycine, a versatile fluorescent probe in proteins, has been synthesized in five steps from commercially available (7-hydroxycoumarin-4-yl)acetic acid. The key step involves the alkylation of a glycine-enolate equivalent.
This paper reports on the synthesis and characterization of two Schiff bases bearing 1,2,4-triazolic moieties, namely 4H-4-(2-hydroxy-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole and 4H-4-(4-nitro-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole using thin layer chromatography, melting interval, elemental analysis, spectroscopy and thermal stability studies.
