Classes of Byzantine Fault-Tolerant Algorithms for Dependable Distributed Systems.

This thesis concentrates on the design of new algorithms for fault-tolerant systems based on system-level hardware masking redundancy. It is argued that any system in which a reliability improvement of at least a factor 100 is required should be based on system-level hardware masking redundancy. The technique of system-level hardware masking redundancy is applicable in a redundant system consisting of a number of processors, in which the system services are replicated on the different processors, and provides resilience to a limited number of faulty processors in the system. The technique is most effective in a distributed system, since the autonomous nature and geographical distribution of the processors in such a system largely contribute to achieve independency between failures of different processors, which improves the reliability of the system

Chiral cosmic strings in supergravity

We consider F and D-term cosmic strings formed in supersymmetric theories. Supersymmetry is broken inside the string core, but restored outside. In global SUSY, this implies the existence of goldstino zero modes, and the string potentially carries fermionic currents. We show that these zero modes do not survive the coupling to gravity, due to the super Higgs mechanism. Therefore the superconductivity and chirality properties are different in global and local supersymmetry. For example, a string formed at the end of D-term inflation is chiral in supergravity but non-chiral in global SUSY.Comment: 14 pages, no figure

Triple-targeting Gram-negative selective antimicrobial peptides capable of disrupting the cell membrane and lipid A biosynthesis

Early lipid A biosynthesis is a potential antimicrobial target as this is an essential component of lipid A producing Gram-negative bacteria. Herein, we introduce a potent and highly synergistic Gram-negative selective triple-targeting antimicrobial peptide. The peptide contains a dual lipid A biosynthesis inhibiting sequence and an antimicrobial sequence

2009 International Pinot Noir Celebration Program

This document is the 2009 program for the International Pinot Noir Celebration (IPNC), held annually on the campus of Linfield College in McMinnville, Oregon. The program contains a detailed schedule of the celebration’s major events, presentations, and meals, as well as information regarding guest speakers, chefs, and artists visiting the campus. The program also includes a short description of all participating wineries for 2009, both foreign and domestic, along with a listing of the IPNC board of directors and all major supporters and contributors to the event
