The binary-couplings neural network used as an associative memory is studied under the eeects of synaptic damage. The model of damage is to ip synapses (Jij ! ?Jij) randomly with a probability. A simple model based on a network with constant stabilities is proposed that allows the calculation of the storage properties of the damaged networks. The networks prove to be fault-tolerant at low stora...

The capacity of rainforests to recover from logging disturbance is difficult to model due to the compounding interactions between long-term disturbance effects, natural dynamics, site characteristics and tree species regeneration strategies. The aim of this study was to develop a quantitative model using over three decades of data from stands subjected to various levels of disturbance ranging f...

The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rates...

As the use of fiber-reinforced polymer composites grows in aerospace structures, there is an emerging need to implement damage tolerant approaches. The in-situ synchrotron X-ray tomography enables direct observations progressive relative microstructural features, which are studied a T650/5320 laminate composite with two layups via monotonic tension. Specifically, interactions micromechanical me...

The molecular chaperone heat shock protein101 (HSP101) is required for acquired thermotolerance in plants and other organisms. To identify factors that interact with HSP101 or that are involved in thermotolerance, we screened for extragenic suppressors of a dominant-negative allele of Arabidopsis thaliana HSP101, hot1-4. One suppressor, shot1 (for suppressor of hot1-4 1), encodes a mitochondria...

Metal Additive Manufacturing (AM) allows the fabrication of intricate shaped parts that cannot be produced with conventional manufacturing techniques. Despite advantages this novel technology, main drawback is inferior fatigue performance AM metal materials and due to presence process-induced defects act as initial cracks. Reliable modeling methods can assist design characterization components ...

Bypassing of DNA lesions by damage-tolerant DNA polymerases depends on the interaction of these enzymes with the monoubiquitylated form of the replicative clamp protein, PCNA. We have analyzed the contributions of ubiquitin and PCNA binding to damage bypass and damage-induced mutagenesis in Polymerase η (encoded by RAD30 ) from the budding yeast Saccharomyces cerevisiae . We report here that a ...
