[Enjoying research on lysozymes for 42 years].
I have pursued research on lysozymes for 42 years. During that time, I made Several new findings, some of them by chance. My enjoyment of the following areas is reviewed: the story of tryptophan; protease digestion mechanisms; peptide mapping with RP-HPLC; gene engineering; renaturation of protein; catalytic residues; fluctuation and function; stabilization; folding; antigenecity; tolerance; an...
متن کاملRevisiting Schurs bound on the largest singular value
We give upper and lower bounds on the largest singular value of a matrix using analogues to walks in graphs. For nonnegative matrices these bounds are asymptotically tight. In particular, the following result improves a bound due to Schur. If A = (aij) is an m n complex matrix, its largest singular value satis es 2 (A) max i2[m] P j2[n] jaij j cj max aij 6=0 ricj ; where ri = P k2[n] jaikj ; cj...

متن کاملA conjecture on binary sequences with the "Trinomial property"
Periodic binary sequences with the \trinomial property" are considered. A conjecture of Golomb and Gong concerning these sequences is disproved.
متن کاملThe Ramsey property for collections of sequences not containing all arithmetic progressions
A familyB of sequences has the Ramsey property if for every positive integer k, there exists a least positive integer fB(k) such that for every 2-coloring of f1;2; : : : ; fB(k)g there is a monochromatic k-term member of B. For fixed integers m > 1 and 0 q < m, let Bq(m) be the collection of those increasing sequences of positive integers fx1; : : : ;xkg such that xi+1 xi q(mod m) for 1 i k 1. ...
