Comment on "Mass and K Lambda coupling of N*(1535)"

It is argued in [1] that when the strong coupling to the K Lambda channel is considered, Breit-Wigner mass of the lightest orbital excitation of the nucleon N(1535) shifts to a lower value. The new value turned out to be smaller than the mass of the lightest radial excitation N(1440), which effectively solved the long-standing problem of conventional constituent quark models. In this Comment we show that it is not the Breit-Wigner mass of N(1535) that is decreased, but its bare mass. [1] B. C. Liu and B. S. Zou, Phys. Rev.

Fearless: Yaou Liu

Humbly and passionately serving the campus community as a true “servant leader” for the past three-and-a-half years, actively engaging in dialogues and initiatives to promote awareness about social injustices, and constantly striving to learn more, act more, and teach more, Yaou Liu ’14, is a fearless role model for the campus community, showing in everything she does a restless passion to see the injustices in the world righted, awareness increased, and the future changed for the better. She is an inspiring, courageous student who has enriched the lives of many both on campus and in the greater Gettysburg community, using her leadership skills to express what she believes, and lead others to understanding. Her time here at Gettysburg has changed her, but she, too, has changed Gettysburg. [excerpt

Cracking the Agrippa Code: Cryptography for the Digital Humanities

In The Laws of Cool, Liu (2004) argues that the art book Agrippa (A Book of the Dead) (Gibson, 1992) is an exhibit of destructive creativity. According to Liu, the book’s great auto-da-fé  occurs when the software program, which is included with the book, displays an electronic poem, and then self-encrypts, a mechanism that destroys or “permanently disappears” (p. 340) the poem. This article argues that Liu’s understanding of encryption is incorrect. Encryption is not destruction because enciphered text is necessarily subject to cryptanalysis (“cracking”). Relatedly, this article demonstrates that Kirschenbaum’s thesis of “no round trip” is mistaken (Kirschenbaum, Reside, & Liu, 2008). Agrippa was fully cracked and reverse-engineered in the course of an online, global cryptanalysis challenge. This article describes the forensic details of Agrippa and its cryptographic routines
