We have investigated the dynamics of underdamped Josephson junctions. In addition to the usual crossover between macroscopic quantum tunnelling and thermally activated (TA) behaviour we observe in our samples with relatively small Josephson coupling EJ , for the first time, the transition from TA behaviour to underdamped phase diffusion. Above the crossover temperature the threshold for switching into the finite voltage state becomes extremely sharp. We propose a (T, EJ ) phase-diagram with various regimes and show that for a proper description of it dissipation and level quantization in a metastable well are crucial.

Our aim in this paper is to explore ways of modeling the distribution of pause durations in conversation using oscillator models (Wilson, Wilson 2006), and to consider how these models might be integrated into our Coupled Oscillator Model of speech timing (COM (

This paper describes the University of Helsinki's submissions to the WMT18 shared news translation task for English-Finnish and English-Estonian, in both directions. This year, our main submissions employ a novel neural architecture, the Transformer, using the open-source OpenNMT framework. Our experiments couple domain labeling and fine tuned multilingual models with shared vocabularies between the source and target language, using the provided parallel data of the shared task and additional back-translations. Finally, we compare, for the English-to-Finnish case, the effectiveness of different machine translation architectures, starting from a rule-based approach to our best neural model, analyzing the output and highlighting future research.
