Trying Auto Reg

Structure, chromosomal localization, and expression of mouse reg genes, reg I and reg II. A novel type of reg gene, reg II, exists in the mouse genome.

We previously identified a gene, reg (i.e. regenerating gene), in the screening of a regenerating islet-derived cDNA library of rat (Terazono, K., Yamamoto, H., Takasawa, S., Shiga, K., Yonemura, Y., Tochino, Y., and Okamoto, H. (1988) J. Biol. Chem. 263, 2111-2114), and isolated a human reg cDNA and gene (Watanabe, T., Yonekura, H., Terazono, K., Yamamoto, H., and Okamoto, H. (1990) J. Biol. C...

REG Challenge Preface

Trying to Understand PEG

Parsing Expression Grammar (PEG) encodes a recursivedescent parser with limited backtracking. Its properties are useful in many applications. In its appearance, PEG is almost identical to a grammar in the Extended Backus-Naur Form (EBNF), but may define a different language. Recent research formulated some conditions under which PEG is equivalent to its interpretation as EBNF. However, PEG has ...

Trying to Understand RoboCup

“Football is a very simple game. For 90 minutes, 22 men go running after the ball, and at the end, the Germans win.” Although the game is simple, analyzing it can be hard. Just what makes one team better than another? How much difference do tactics make? Is there really such a thing as a “lucky win”? Here, we try to answer these questions in the context of RoboCup. We take the giant set of log ...

T reg cells get specific

Naturally occurring regulatory T (T reg) cells suppress T cell–driven autoimmunity and chronic inflammation. Although the origin and function of these cells has been widely studied, the specificity of their T cell receptors (TCRs)—whether for self or foreign antigens on target cells—remains a matter of debate. Prevailing opinion comes down on the side of self-antigen. But now Suffia and colleag...
