Matrix model approach to the N = 2 U (N) gauge theory with matter in the fundamental representation
Date: 2003-01-01
Creator: Stephen G. Naculich, Howard J. Schnitzer, Niclas Wyllard
Access: Open access
- We use matrix model technology to study the N = 2 U (N) gauge theory with Nf massive hypennultiplets in the fundamental representation. We perform a completely perturbative calculation of the periods ai and the prepotential F(a) up to the first instanton level, finding agreement with previous results in the literature. We also derive the Seiberg-Witten curve and differential from the large-M solution of the matrix model. We show that the two cases Nf < N and N ≤ Nf < 2N can be treated simultaneously. © SISSA/ISAS 2003.
Elliptic models, type IIB orientifolds, and the AdS/CFT correspondence
Date: 2000-12-18
Creator: Isabel P. Ennes, Carlos Lozano, Stephen G. Naculich, Howard J. Schnitzer
Access: Open access
- We analyze the large N supergravity descriptions of the class of type IIB models T-dual to elliptic type IIA brane configurations containing two orientifold 6-planes and up to two NS 5-branes. The T-dual IIB configurations contain N D3-branes in the background of an orientifold 7-plane and, in some models, a Z2 orbifold and/or D7-branes, which give rise to four-dimensional N=2 (or N=4) gauge theories with at most two factors. We identify the chiral primary states of the supergravity theories, and match them to gauge invariant operators of the corresponding superconformal theories using Maldacena's duality. © 2000 Elsevier Science B.V.
Probing the mechanism of recognition of ssDNA by the Cdc13-DBD
Date: 2008-03-01
Creator: Aimee M. Eldridge, Deborah S. Wuttke
Access: Open access
- The Saccharomyces cerevisiae protein Cdc13 tightly and specifically binds the conserved G-rich single-stranded overhang at telomeres and plays an essential role in telomere end-protection and length regulation. The 200 residue DNA-binding domain of Cdc13 (Cdc13-DBD) binds an 11mer single-stranded representative of the yeast telomeric sequence [Tel11, d(GTGTGGGTGTG)] with a 3 pM affinity and specificity for three bases (underlined) at the 5′ end. The structure of the Cdc13-DBD bound to Tel11 revealed a large, predominantly aromatic protein interface with several unusual features. The DNA adopts an irregular, extended structure, and the binding interface includes a long (∼30 amino acids) structured loop between strands β2-β3 (L2-3) of an OB-fold. To investigate the mechanism of ssDNA binding, we studied the free and bound states of Cdc13-DBD using NMR spectroscopy. Chemical shift changes indicate that the basic topology of the domain, including L2-3, is essentially intact in the free state. Changes in slow and intermediate time scale dynamics, however, occur in L2-3, while conformational changes distant from the DNA interface suggest an induced fit mechanism for binding in the 'hot spot' for binding affinity and specificity. These data point to an overall binding mechanism well adapted to the heterogeneous nature of yeast telomeres. © 2008 The Author(s).
“The Spirit of Turbulence”: East Indian Political Imaginaries in Early 20th Century British Guiana
Date: 2020-01-01
Creator: Faria A Nasruddin
Access: Open access
- After the abolition of slavery, the Colonial Office instituted an indentured labor scheme that lasted from 1838 to 1917, in which they brought East Indians to the plantation colonies as laborers under five year contracts. Due to the planter class’ desire for permanent sources of labor in British Guiana, the Colonial Government incentivized East Indians to permanently settle. East Indians thus dominated the British Guiana’s agricultural landscape and became the single largest ethnicity in the Colony by 1920. This thesis explores the early negotiations of the meaning of diaspora and diasporic citizenship for East Indians in British Guiana. They comprised a diverse conglomerate of different socio-economic positions: agricultural estate laborers, village residents, and middle-class business professionals. Each socioeconomic group had a different lived experience in the colony and different outlook on what it meant to be a creole-born East Indian. This thesis traces the multiple and contingent ideas of citizenship and nationality that were circulating at the time. Against a backdrop of changing imperial politics that promoted modernity and the discourse of the nation, East Indian visions centered around how to construct permanence, and negotiate belonging. By drawing on colonial documentation–local reports, commission transcripts, personal correspondence–and documentation produced by East Indians–memorandums, speeches, and books–this thesis ultimately argues that East Indians came to view culture as integral to their self-worth and definitions of place within the imperial system. Culture thus became the primary lens to negotiate the various meaning of citizenship and place in the imperial-national moment.

Thompson's group F is not almost convex
Date: 2003-12-01
Creator: Sean Cleary, Jennifer Taback
Access: Open access
- We show that Thompson's group F does not satisfy Cannon's almost convexity condition AC(n) for any positive integer n with respect to the standard generating set with two elements. To accomplish this, we construct a family of pairs of elements at distance n from the identity and distance 2 from each other, which are not connected by a path lying inside the n-ball of length less than k for increasingly large k. Our techniques rely upon Fordham's method for calculating the length of a word in F and upon an analysis of the generators' geometric actions on the tree pair diagrams representing elements of F. © 2003 Elsevier Inc.
