Sources of resistance to pathotype QCC of Puccinia graminis f. sp. tritici in barley
No full textThe occurrence of a wheat stem rust (Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.) pathotype (Pgt-QCC) with virulence for the Rpg1 gene in barley (Hordeum vulgare L.) necessitated the search for resistant barley germplasm. From preliminary screenings of over 18 000 barley accessions, 13 lines were identified as possessing resistance to pathotype QCC: ‘Diamond’, ‘Hietpas 5’, Q21861, PC 11, PC 84, PC 249, PC 250, CI 5541, PI 452406, PI 452421, PI 477843, PI 477854, and PI 477860. This study was conducted to further characterize the reaction of the selected lines to pathotype QCC. The reaction was assessed by evaluating infection types at the seedling stage and infection responses at the adult plant stage in the greenhouse, and by evaluating disease severity and infection responses at the adult plant stage in the field compared to susceptible cultivars. Most lines exhibited low to intermediate infection types at the seedlings stage and moderately resistant to moderately susceptible infection responses at the adult plant stage in the greenhouse experiments. Among the selected lines, Q21861 exhibited the highest level of resistance at both the seedling and adult plant stages. These lines may provide an adequate level of resistance to pathotype QCC for cultivar development.Steffenson, Brian; Jin, Yue; Fetch, Thomas G.. (1994).

The Thomas G. Everett Collection: A Compendium of Selected Materials Donated by Bass Trombonist Thomas G. Everett
No full textabstract: This document is a compendium of the materials that are housed within the special collections donated by Thomas Everett. In August 2016, the Arizona State University School of Music, through the efforts of retired Professor of Trombone Douglas Yeo, received a donation of materials from Thomas Everett, founder of the International Trombone Association and retired director of bands at Harvard University.
This donation contains published and unpublished music, numerous letters, and various drafts of his book, An Annotated Guide to Bass Trombone Literature. Over the course of two-and-a-half years, the donation was catalogued for the university by the author. Materials from the donation were sent into public circulation or sent into special collections within the ASU School of Music Library.Dissertation/ThesisDoctoral Dissertation Music 201
Christiformitas in Nicholas of Cusa’s Roman Sermons (1459)
No full textNicholas of Cusa (1401-1464) served as vicar of Rome in the absence of Pope Pius II at the Congress of Mantua (1459). Cusanus held a synod and did visitations of major churches. His sermons for these events emphasized conformity with Christ as the means of knowing God.This is the Version of Record (VoR) of the article that was originally published in Perspectives in the Arts and Humanities Asia, Volume 1, Number 1 (2011
Automated Detection, Exploitation, and Elimination of Double-Fetch Bugs using Modern CPU Features
No full textInternational audienceDouble-fetch bugs are a special type of race condition, where an unprivileged execution thread is able to change a memory location between the time-of-check and time-of-use of a privileged execution thread. If an unprivileged attacker changes the value at the right time, the privileged operation becomes inconsistent, leading to a change in control flow, and thus an escalation of privileges for the attacker. More severely, such double-fetch bugs can be introduced by the compiler, entirely invisible on the source-code level. We propose novel techniques to efficiently detect, exploit, and eliminate double-fetch bugs. We demonstrate the first combination of state-of-the-art cache attacks with kernel-fuzzing techniques to allow fully automated identification of double fetches. We demonstrate the first fully automated reliable detection and exploitation of double-fetch bugs, making manual analysis as in previous work superfluous. We show that cache-based triggers outperform state-of-the-art exploitation techniques significantly, leading to an exploitation success rate of up to 97 %. Our modified fuzzer automatically detects double fetches and automatically narrows down this candidate set for double-fetch bugs to the exploitable ones. We present the first generic technique based on hardware transactional memory, to eliminate double-fetch bugs in a fully automated and transparent manner. We extend defensive programming techniques by retrofitting arbitrary code with automated double-fetch prevention , both in trusted execution environments as well as in syscalls, with a performance overhead below 1 %

The Gospel of Thomas and the earliest texts of the synoptic gospels
No full textResearch on the Gospel of Thomas in the last quarter of a
century has made it clear that the origins of this apocryphal gospel
cannot
be
satisfactorily explained from a single point of view. The
author thus suggests that Thomas
be
understood as a growing collection
of sayings which originated in various places and languages, with some
logia being added to the collection after its inception. While this
suggestion is by no means new, there have been few extensive attempts
to study Thomas from such a presupposition.
Due to the need for a control group, only the logia which have
rather close parallels to the Synoptic gospels are investigated. Verbal and textual affinities are noted between these logia and the earliest texts of the Gospels (the Coptic versions, the Diatessaron, the
Old Syriac version, and other early versions and Christian writings).
Various degrees of probable contact between each logion and these
texts are assigned.
The results of this study give some idea as to the place of
origin, the original language, and the approximate date at which certain logia were added to the collection. Those sayings which show a
closer affinity to the Diatessaron, the Old Syriac version, or other
Syrian writings may
be
considered as having been added to the sayings
collection as it circulated in its earliest form, possibly in a Semitic language. Other logia which show no signs of awareness of a
Syrian reading, but which are similar to variants found in the Coptic
versions or other Egyptian texts, may well have originated in Egypt
and been added to the collection at a later stage. These results,
however, must await verification by those who might approach Thomas
from related, but different, perspectives

"The Economics of Outsourcing: How Should Policy Respond?"
No full textAccording to Research Associate Thomas A. Palley, global outsourcing represents a new economic challenge that calls for a new set of institutions. In this brief, he expands upon the problems of offshore outsourcing as outlined in Public Policy Brief no. 86 and focuses on the microeconomic foundations. He argues that outsourcing is a central element of globalization that is best understood as a new form of competition. Palley urges policymakers to understand the economic basis of outsourcing in order to develop effective policies, and suggests that they focus on enhancing national competitiveness and establishing new rules that govern the nature of global competition.
