We demonstrate an explicit numerical method for accurate calculation ofthe analytic continuation of the scattering matrix, describing the multichannelscattering by a quantum well, to the unphysical region of complexvalues of the energy.Results of calculations show that one or severalpoles of the S-matrix exist, corresponding to the over-barrier res
Background.Autism Spectrum Disorder (ASD) is characterised by difficulties in social communication and restrictive, repetitive patterns of behaviour.ASD represents a spectrum of functional manifestations, involving varying levels of severity in intellectual activity and social interaction.Adolescence involves various physical and cognitive changes,
In most mammalian brains, the subventricular zone (SVZ) is a germinative layer that maintains neurogenic activity throughout adulthood.Neuronal precursors arising from this region migrate through the rostral migratory stream (RMS) and reach the olfactory bulbs where they differentiate and integrate into the local circuitry.Recently, studies have sh
Abstract Background Meiosis is a critical process in the reproduction and life cycle of flowering plants in which homologous chromosomes pair, synapse, recombine and segregate.Understanding meiosis will not only advance our knowledge of the mechanisms of genetic recombination, but also has substantial applications in crop improvement.Despite the tr
The dissemination of low-carbon technologies, such as urban photovoltaic distributed generation, imposes new challenges to the operation of distribution grids.Distributed generation may introduce significant net-load asymmetries between feeders in the course of the day, resulting in higher losses.The dynamic reconfiguration of the grid could mitiga
