Small Byzantine Quorum Systems

by Jean-Philippe Martin, Lorenzo Alvisi, Michael Dahlin - DISTRIBUTED COMPUTING , 2001
"... In this paper we present two protocols for asynchronous Byzantine Quorum Systems (BQS) built on top of reliable channels---one for self-verifying data and the other for any data. Our protocols tolerate Byzantine failures with fewer servers than existing solutions by eliminating nonessential work in ..."

THE 3–CONNECTED GRAPHS WITH EXACTLY THREE NON-ESSENTIAL EDGES

by James Oxley, Haidong Wu
"... Abstract. An edge e of a simple 3-connected graph G is essential if neither the deletion G\e nor the contraction G/e is both simple and 3–connected. Tutte’s Wheels Theorem proves that the only simple 3–connected graphs with no non-essential edges are the wheels. In earlier work, as a corollary of a ..."

Essential and Non-essential Work of Fracture of PI/SiO2 Hybrid Thin Films

by Z. D. Wang, J. J. Lu , 2007
"... Abstract Essential work of fracture (EWF) analysis is used to study the effect of the silica doping level on fracture toughness of polyimide/silica (PI/SiO2) hybrid films. By using double-edge-notched-tension (DENT) specimens with different ligament lengths, it seems that the introduction of silica ..."
Abstract - Add to MetaCart
additive can improve the specific essential work of fracture (we) of PI thin films, but the specific non-essential work of fracture (βwp) will decease significantly as the silica doping level increasing from 1 to 5 wt.%, and even lower than that of neat PI. The failure process of the fracture

A forward genetic screen reveals essential and non-essential RNAi factors in Paramecium tetraurelia

by Simone Marker, Quentin Carradec, Olivier Arnaiz, Eric Meyer - Nucleic Acids Res , 2014
"... In most eukaryotes, small RNA-mediated gene si-lencing pathways form complex interacting net-works. In the ciliate Paramecium tetraurelia, at least two RNA interference (RNAi) mechanisms coexist, involving distinct but overlapping sets of protein fac-tors and producing different types of short inter ..."

A Precise Bicoid Gradient Is Nonessential during Cycles 11–13 for Precise Patterning in the Drosophila

by Elena M. Lucchetta, Meghan E. Vincent, Rustem F. Ismagilov
"... Background: During development, embryos decode maternal morphogen inputs into highly precise zygotic gene expression. The discovery of the morphogen Bicoid and its profound effect on developmental programming in the Drosophila embryo has been a cornerstone in understanding the decoding of maternal i ..."

inputs. Bicoid has been described as a classical morphogen that forms a concentration gradient along the antero-posterior axis of the embryo by diffusion and initiates expression of target genes in a concentration-dependent manner in the syncytial blastoderm. Recent work has emphasized the stability

Scalable Load Balancing Strategies for Parallel A* Algorithms

by Shantanu Dutt, Nihar R. Mahapatra - Journal of Parallel and Distributed Computing , 1994
"... In this paper, we develop load balancing strategies for scalable high-performance parallel A* algorithms suitable for distributed-memory machines. In parallel A* search, inefficiencies such as processor starvation and search of nonessential spaces (search spaces not explored by the sequential algori ..."

The QE strategy possesses certain unique quantitative and qualitative load balancing properties that enable it to significantly reduce starvation and nonessential work. Consequently, we obtain a highly scalable parallel A* algorithm

Diversity-based, model-guided construction of synthetic gene networks with predicted functions. Nat Biotechnol 27: 465–471

by Tom Ellis, Xiao Wang, James J. Collins , 2009
"... Engineering artificial gene networks from modular components is one of the major goals of synthetic biology. However, the construction of gene networks with predictable functions remains hampered by a lack of suitable components and the fact that assembled networks often require extensive, iterative ..."

, iterative retrofitting to work as intended. Here we present an approach that couples libraries of diversified components (synthesized with randomized non-essential sequence) with in silico modeling to guide predictable gene network construction without the need for post-hoc tweaking. We demonstrate our

APPRECIATIVE INQUIRY: NEW THINKING AT WORK

by Sherene Zolno
"... Abstract: Many of us have been taught that legitimate knowledge derives from an emphasis on what is rational, objective, empirical, and problematic. Called ‘critical thinking, ’ this ability to identify and successfully solve problems is viewed in most workplace settings as crucial for organizationa ..."

for organizational effectiveness and change. Other means of understanding reality – “appreciation, ” “valuing,” and “affirming, ” – are considered Pollyannish, i.e., soft-headed and non-essential. By legitimizing only the first form of thinking we shut down an entire mode of learning and severely limit the capacity

Essential Fracture Work of Nylon 6-Silicate

by Y. Qiao, S. Avlar, S. S. Chakravarthula , 2004
"... ABSTRACT: In a fracture experiment of polymers, the total fracture work usually consists of an essential part as-sociated with the plastic deformation at the crack tip and a nonessential part related to the viscous relaxation in the background. In this article, the essential fracture work in nylon 6 ..."
