The formation, isolation, and characterizat,ion of two isomeric, inactive derivatives of ribonuclease, l-carboxymethylhistidinc119and 3-carboxymethylhistidine-12-ribonuclease,1 were dcscribed in the preceding paper (2). Studies on the course of the alkylation reaction and on some of the properties of the two alkylated derivatives are the subject of the present communication. It has been found t...

In this paper, we mainly consider the Cauchy problem of a hyperbolic-parabolic model vasculogenesis in dimension three. We first obtain optimal $ L^2 $-decay rate solution and its highest order derivatives when initial perturbation is small H^3(\mathbb{R}^3) bounded L^1(\mathbb{R}^3) $. Here, optimality means there no decay loss for highest-order spatial derivatives. This refines that [21], whe...
