[Review of] Roger Daniels, Sandra C. Taylor, and Harry H. L. Kitano, eds. Japanese Americans: From Relocation to Redress
This collection of previously unpublished essays grew out of a conference in Salt Lake City in 1983 on the incarceration of Japanese Americans during World War II and the issue of redress. It includes essays by the three editors and contributions, some no more than brief notes, by twenty-seven individuals. It also includes a detailed chronology of Japanese-American history and comprehensive bibliographical notes
[Review of] Hyung-Chan Kim, ed. Dictionary of Asian American History
A result of the collaboration of several dozen specialists, this new reference work provides a wealth of information about the largest groups of immigrants who went east to settle in the United States: the Chinese, Japanese, Koreans, Indians, Filipinos, Pacific Islanders, and Southeast Asians. It includes brief historical sketches of each of these groups and essays on a number of topics such as Asian-American literature, immigration law, and educational issues that affect Asian Americans. It also includes alphabetically arranged entries on hundreds of topics, a chronology of Asian-American history, and a bibliography
Color Superconductivity in N=2 Supersymmetric Gauge Theories
We study vacuum structure of N=2 supersymmetric (SUSY) QCD, based on the
gauge group SU(2) with N_f=2 flavors of massive hypermultiplet quarks, in the
presence of non-zero baryon chemical potential (\mu). The theory has a
classical vacuum preserving baryon number symmetry, when a mass term, which
breaks N=2 SUSY but preserves N=1 SUSY, for the adjoint gauge chiral multiplet
(m_{ad}) is introduced. By using the exact result of N=2 SUSY QCD, we analyze
low energy effective potential at the leading order of perturbation with
respect to small SUSY breaking parameters, \mu and m_{ad}. We find that the
baryon number is broken as a consequence of the SU(2) strong gauge dynamics, so
that color superconductivity dynamically takes place at the non-SUSY vacuum.Comment: 15 pages, 9 figures, a figure and discussions added in Sec. 4,

Rescue with an anti-inflammatory peptide of chickens infected H5N1 avian flu
Chickens suffering from avian flu caused by H5N1 influenza virus are destined to die within 2 days due to a systemic inflammatory response. Since HVJ infection (1,2) and influenza virus infection (3,4) cause infected cells to activate homologous serum complement, the systemic inflammatory response elicited could be attributed to the unlimited generation of C5a anaphylatoxin of the complement system, which is a causative peptide of serious inflammation. In monkeys inoculated with a lethal dose of LPS (4 mg/kg body weight), inhibition of C5a by an inhibitory peptide termed AcPepA (5) rescued these animals from serious septic shock which would have resulted in death within a day (6). Therefore, we tested whether AcPepA could also have a beneficial effect on chickens with bird flu. On another front, enhanced production of endothelin-1 (ET-1) and the activation of mast cells (MCs) have been implicated in granulocyte sequestration (7). An endothelin receptor derived antisense homology box peptide (8) designated ETR-P1/fl was shown to antagonize endothelin A receptor (ET-A receptor) (9) and reduce such inflammatory responses as endotoxin-shock (10) and hemorrhagic shock (11), thereby suppressing histamine release in the circulation (12). Thus, we also administered ETR-P1/fl to bird flu chickens expecting suppression of a systemic inflammatory response
Diquark Higgs at LHC
Existence of color sextet diquark Higgs fields with TeV masses will indicate
a fundamentally different direction for unification than conventional grand
unified theories. There is a class of partial unification models based on the
gauge group that implement the seesaw
mechanism for neutrino mass with seesaw scale around GeV, where
indeed such light fields appear naturally despite the high gauge symmetry
breaking scale. They couple only to up-type quarks in this model.
We discuss phenomenological constraints on these fields and show that they
could be detected at LHC via their decay to either or single top + jet. We
also find that existing Tevatron data gives a lower bound on its mass somewhere
in the 400-500 GeV, for reasonable values of its coupling.Comment: 5 pages, 3 figure
