Profile. The constant psychiatrist: an interview with Michael Kopelman

Profile of Michael B. A. Oldstone. Interview by Nicholette Zeliadt.

Viruses lie at the heart of some of humanity’s most pernicious and devastating diseases, such as AIDS, hepatitis, and influenza. Michael Oldstone, a recently elected member of the National Academy of Sciences and a professor of immunology and microbiology at The Scripps Research Institute in La Jolla, California, has devoted his career to a molecular understanding of how viruses infect cells, e...

Tricyclic graphs with maximum Merrifield-Simmons index

It is well known that the graph invariant, ‘the Merrifield–Simmons index’ is important one in structural chemistry. The connected acyclic graphs with maximal and minimal Merrifield–Simmons indices are determined by Prodinger and Tichy [H. Prodinger, R.F. Tichy, Fibonacci numbers of graphs, Fibonacci Quart. 20 (1982) 16–21]. The sharp upper and lower bounds for theMerrifield–Simmons indices of u...

A Functional Limit Theorem for the Profile of Search Trees by Michael Drmota,1 Svante Janson

We study the profile Xn,k of random search trees including binary search trees and m-ary search trees. Our main result is a functional limit theorem of the normalized profile Xn,k/EXn,k for k = α logn in a certain range of α. A central feature of the proof is the use of the contraction method to prove convergence in distribution of certain random analytic functions in a complex domain. This is ...
