STAcy E. FERGusON AND CRAIG 6. THOMPSON LYMPHOCYTE DEVELOPMENT
Vertebrates are able to mount specific immune responses because they possess a vast array of antigen-specific B and T cells. In B cells, the antigen receptor is a membranebound form of immunoglobulin, whereas in T cells the antigen-specific component of the T cell receptor (TCR) is composed of a heterodimer of either TCR c1 and j3 gene products or TCR y and 61 gene products. In the germline, th...
متن کاملBy William C . Thompson , Laurence D . Mueller , and Dan E .
experts sometimes disagree about the interpretation and statistical characterization of test results. This article will describe the key controversies and will explain what lawyers need to know to recognize and deal with controversial types of DNA evidence. When labs try to “type” samples that contain too little DNA, or DNA that is too degraded, the results of the DNA test can be unreliable. Th...
متن کاملThompson Digraphs: A Characterization
A nite-state machine is called a Thompson machine if it can be constructed from a regular expression using Thompson's construction. We call the underlying digraph of a Thompson machine a Thompson di-graph. We establish and prove a characterization of Thompson digraphs. As one application of the characterization, we give an algorithm that generates an equivalent regular expression from a Thompso...
متن کاملThompson rings in a disk
We discuss basic principles of self-organization of a finite number of charged particles interacting via the 1/r Coulomb potential in a disk geometry. The analysis is based on the cyclic symmetry and periodicity of the Coulomb interaction between particles located on several rings. As a result, a system of equations is derived, which provides the shell structure exhibited by charged particles. ...
متن کاملA conversation with Craig Thompson.
Craig Thompson, President and CEO of Memorial Sloan Kettering Cancer Center, is a medical oncologist and immunologist who has made fundamental contributions to our understanding of how cells — from B and T cells to stem cells and cancer cells — survive and replicate. See the full interview at https://www.jci. org/videos/cgms to hear Thompson’s (Figure 1) stories about being a remedial reader, t...
