Direct quantile regression involves estimating a given quantile of a response variable as a function of input variables. We present a new framework for direct quantile regression where a Gaussian process model is learned, minimising the expected tilted loss function. The integration required in learning is not analytically tractable so to speed up the learning we employ the Expectation Propagat...

The study presented here investigates how different degrees of conceptual integration, as predicted by direct and indirect reported speech, effect speakers’ prosodic behaviour in interaction. It makes a threeway distinction between authentic direct, false direct and indirect reported speech and predicts that greater conceptual distance, predicted by authentic direct reported speech, will lead t...

Micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. An essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. Efficiency and robustness of the implementation hinge on the type of int...

Reference [1] introduces a method for the computation of the Floquet matrix, which is a time-history solution of a periodic-coefficient system over one period. Reference [2] generalizes both first order and second order forms to the case for which all coefficients are periodic. Numerical results for rotor flap-lag response show the Sinha method to be much more efficient than conventional time-m...

We describe a plant protoplast transformation method that provides transformants with a simple pattern of integration of a foreign gene. The approach is to deliver into plant protoplasts by direct gene transfer the Agrobacterium virulence genes virD1 and virD2 with or without virE2, together with a target plasmid containing a gene of interest flanked by Agrobacterium T-DNA border repeat sequenc...

This work introduces a time-adaptive strategy that uses a refinement estimator based on the first Frenet curvature. In dynamics, a time-adaptive strategy is a mechanism that interactively proposes changes to the time step used in iterative methods of solution. These changes aim to improve the relation between quality of response and computational cost. The method here proposed is suitable for a...
