    The broad bean nodulin VfENOD18 is a member of a novel family of plant proteins with homologies to the bacterial MJ0577 superfamily

    Full-length transcript sequences were isolated from broad bean root nodules, which encode a novel nodulin designated VfENOD18. The corresponding transcripts were detected in early and in late stages of nodule...

    Genomic organization and expression properties of the MtSucS1 gene, which encodes a nodule-enhanced sucrose synthase in the model legume Medicago truncatula

    We have isolated and sequenced a sucrose synthase (SucS) cDNA from the model legume Medicago truncatula. This cDNA (MtSucS1) contains an ORF of 2418 bp, coding for a protein of 805 amino acids with a molecular m...

    Recognition of visual stimuli from multiple neuronal activity in monkey visual cortex

    Response patterns recorded with 30 microelectrodes from area 17 of anaesthetized monkeys are analysed. A proportion of the patterns are used to define prototype response patterns. These in turn are used to rec...

    Analysis, classification, and coding of multielectrode spike trains with hidden Markov models

    It is shown that hidden Markov models (HMMs) are a powerful tool in the analysis of multielectrode data. This is demonstrated for a 30-electrode measurement of neuronal spike activity in the monkey's visual co...

    Analysing ion channels with hidden Markov models

    Ion channel current amplitudes (μ) and open probabilities (P o) have been analysed so far by defining a 50% threshold to distinguish between open and closed states of the channels. With this standard method (SM) ...

    From Electronic Structure to Phase Diagrams

    A first-principles statistical mechanics theory of alloy phase stability is presented. The theory incorporates ab-initio electronic total energies, configurational entropies and vibrational modes into the total f...

    Phase Stability and Diagrams from First Principles

    First principles theories of alloy phase equilibrium have been successfully used in recent years to compute temperature-composition phase diagrams for solid state phases. One particular approach, originating w...

    Is Spike Frequency the Critical Factor in Recognising the Visual Stimulus?

    Our aim was to investigate how visual stimuli could most reliably be recognised on the basis of the spike patterns they evoke in the striate cortex. Recording simultaneously with an array of 30 microelectrodes...

    13C-NMR Investigation of an Oxygen Defect in trans-Polyacetylene

    Trans-polyacetylene is unstable in air and oxygen defects are known to occur. There are a number of speculations on the structure of these defects but their precise nature is unknown. We have performed 13C NMR...
