Recently, an algorithm-based approach using diskless checkpointing has been developed to provide fault tolerance for high-performance matrix operations. With this approach, since fault tolerance is incorporated into the matrix operations, the matrix operations become resilient to any single processor failure or change with low overhead. In this paper, we present a technique called multiple chec...

Many persons exposed to loss or potentially traumatic events manage the stresses of these experiences with minimal to no impact on their daily functioning. The prevalence of this resilient capacity has surprised researchers and clinicians alike and refocused clinical practice. We review three key points about resilience: resilience is different from the process of recovery; resilience in the fa...

The liver is a highly resilient organ that possesses enormous regenerative capacity. This is mediated mainly through the most abundant cell type found in the liver, the hepatocyte. When the regenerative capacity of the hepatocyte is compromised, during chronic or acute liver injury, hepatic progenitor cells (HPCs) are activated to replace the damaged tissue. The HPC resides in a laminin-rich en...

Field studies and laboratory experiments have documented that a key component of resilience is emotional flexibility--the ability to respond flexibly to changing emotional circumstances. In the present study we tested the hypotheses that resilient people exhibit emotional flexibility: (a) in response to frequently changing emotional stimuli and (b) across multiple modalities of emotional respon...

Embedding capacity, distortion and resilience to attacks are three key indicators to the performance of any image watermarking systems. Study has shown that Quantization Index Modulation (QIM) can in general achieve higher embedding capacity than Spread Spectrum (SS) systems at the same level of distortion. However, QIM is more sensitive to simple attacks such as Addi­ tive White Gaussian Noise...

Resilient topologies and routing are among the important topics that were addressed within the HIDENETS project and have been the focus of task 1 of Work Package 3 ‘Resilient Communication’. This document provides the results of the work in this area. The document has the following content: (1) The HIDENETS network architecture is described, introducing the relevant terminology and the use case...

Print-scan resilient watermarking has emerged as an attractive way for document security. This paper proposes a stroke direction modulation technique for watermarking in Chinese text images. The watermark produced by the idea offers robustness to print-photocopyscan, yet provides relatively high embedding capacity without losing the transparency. During the embedding phase, the angles of rotata...

During my doctoral research, I identified new ways of thinking about complexity in organizations. This involved embracing the capacity of complex systems to find their own form of order and coherence, often referred to as self-organization, and then asking the question, "What can organizational leaders do to create the systems and structures that would facilitate emergent change?" Emergent chan...

A non-malleable code is a variant of an encoding scheme which is resilient to tampering attacks. The main idea behind non-malleable coding is that the adversary should not be able to obtain any valuable information about the message. Non-malleable codes are used in tamper-resilient cryptography and protecting memories against tampering attacks. Many different types of non-malleability have alre...

OBJECTIVES To identify plausible mechanisms by which resilience (low mortality rates despite persistent economic adversity) was achieved in some areas in Britain between 1971 and 2001. METHODS Mixed method observational study, combining quantitative analyses of cause- and age group-specific mortality rates, and area sociodemographic and environmental characteristics, with case studies of resi...
