The scientific community has been saddened and diminished by the loss of Stanley J. Korsmeyer, M.D., who died of lung cancer last month at the age of 54. Over the last 25 years, Korsmeyer had been an international leader in the fields of cancer biology and programmed cell death (apoptosis). Through his studies of apoptosis, Korsmeyer helped revolutionize our concepts of carcinogenesis. Korsmeye...

Stanley Cohen [5] was born on 17 November 1922 in Brooklyn, New York. His father was a tailor and his mother a housewife who immigrated to the United States from Russia in the early 1900s. Cohen spent his early education in the New York City public school system, and attended the city college, Brooklyn College [9], for his undergraduate studies.

Little [Adv. Math. 174 (2003), 236–253] developed a combinatorial algorithm to study the Schur-positivity of Stanley symmetric functions and the Lascoux–Schützenberger tree. We generalize this algorithm to affine Stanley symmetric functions, which were introduced recently in [T. Lam: “Affine Stanley symmetric functions,” Amer. J. Math., to appear].
