In the majority o f chronic lymphocytic leukemias (CLL), proliferative B lymphocytes are thought to be frozen in vivo at a given maturat ion stage (1). Recently, several studies have emphasized that CLL cells could be driven to different iate into plasma cells in vitro (with or without proliferation) upon t r iggering by mitogens (2, 3, 4) or T cel l -der ived factors (5, 6). Th u s far, howeve...

In this thesis, we study continuum tree-valued processes. First, we define anabstract framework for these processes, by constructing a metric on the space of locally com-pact, complete R-trees, endowed with a locally finite Borel measure. This topology, calledGromov-Hausdorff-Prokhorov topology, allows for the definition of tree-valued Markov pro-cesses. We then give a new const...
متن کاملA Proof of Jean De Rumeur's Conjecture
We give an elementary proof of Jean de Rumeur's conjecture stating that in any digraph G of diameter D, such that the sum of the indegree and outdegree of every vertex is at most 2d, the number of vertices is at most X i=0;i=D d i : Our result implies that known good solutions in the case d + = d ? = d are also quasi-optimal under the asumption that d + + d ? = 2d.

1. The first indication of the phenomenon.-When we consider a fluid mass in equilibrium, for example, some water in a glass, all the parts of the mass appear completely motionless to us. If we put into it an object of greater density it falls and, if it is spherical, it falls exactly vertically. The fall, it is true, is the slower the smaller the object; but, so long as it is visible, it falls ...
