Anticipatory coarticulation in Hungarian VnC sequences

The duration of the vowel and the nasal was analyzed in the casual pronunciation of Hungarian words containing the sequence V n .C, where ‘.’ is a syllable boundary and C is a stop, affricate, fricative, or approximant. It was found that due to anticipatory coarticulation the duration of n is significantly shorter before fricatives and approximants than before stops and affricates.A teaching algorithm was used to distinguish between stops/affricates and fricatives/approximants in V n C sequences. We used an approach to the classification of C by means of the support vector machine (SVM) and the properties of Radial basis function (RBF) kernel (using MATLAB, version 7.0). The results show close to 95% correct responses for the stop/affricate vs. fricative/approximant distinction of C, as opposed to about 60% correct responses for the classification of the voicing feature of C

The high-resolution map of Oxia Planum, Mars; the landing site of the ExoMars Rosalind Franklin rover mission

This 1:30,000 scale geological map describes Oxia Planum, Mars, the landing site for the ExoMars Rosalind Franklin rover mission. The map represents our current understanding of bedrock units and their relationships prior to Rosalind Franklin’s exploration of this location. The map details 15 bedrock units organised into 6 groups and 7 textural and surficial units. The bedrock units were identified using visible and near-infrared remote sensing datasets. The objectives of this map are (i) to identify where the most astrobiologically relevant rocks are likely to be found, (ii) to show where hypotheses about their geological context (within Oxia Planum and in the wider geological history of Mars) can be tested, (iii) to inform both the long-term (hundreds of metres to ∼1 km) and the short-term (tens of metres) activity planning for rover exploration, and (iv) to allow the samples analysed by the rover to be interpreted within their regional geological context
