Sean Morrison and the Texas brain gain.
In 2007, the Texas state constitution was amended to establish the Cancer Prevention and Research Institute of Texas (CPRIT). The new organization was endowed with $3 billion to invest in cancer research in Texas over the next decade. The funds are intended to drive the recruitment of topnotch scientists to Texas institutions and fund innovative research programs. The JCI recently spoke to Sean...
متن کاملSean Morrison: A root and branch approach to stem cells
T hroughout life, stem cells maintain themselves by dividing to produce one or two daughter stem cells with an identical developmental potential. Although this self-renewal process is fundamental to all types of stem cells, the precise mechanism varies between different tissues and stages of development. Sean Morrison examines the self-renewal of different types of stem cells to understand how ...

This paper produces a recursive formula of the Betti numbers of certain Stanley-Reisner ideals (graph ideals associated to forests). This gives a purely combinatorial definition of the projective dimension of these ideals, which turns out to be a new numerical invariant of forests. Finally, we propose a possible extension of this invariant to general graphs. 0. Introduction Throughout this pape...

We describe a family of elements in Thompson’s group F which present a challenge to finding canonical minimal length representatives for group elements, and which show that F is not combable by geodesics. These elements have the property that there are only two possible suffixes of long lengths for geodesic paths to these elements from the identity; one is of the form g and the other of the for...

We show that the log canonical bundle, κ, of M0,n is very ample, show the homogeneous coordinate ring is Koszul, and give a nice set of rank 4 quadratic generators for the homogeneous ideal: The embedding is equivariant for the symmetric group, and the image lies on many Segre embedded copies of P×· · ·×P, permuted by the symmetric group. The homogeneous ideal of M0,n is the sum of the homogene...
