    Probabilistic tsunami forecasting for early warning

    Tsunami warning centres face the challenging task of rapidly forecasting tsunami threat immediately after an earthquake, when there is high uncertainty due to data deficiency. Here we introduce Probabilistic T...

    Effect of Shallow Slip Amplification Uncertainty on Probabilistic Tsunami Hazard Analysis in Subduction Zones: Use of Long-Term Balanced Stochastic Slip Models

    The complexity of coseismic slip distributions influences the tsunami hazard posed by local and, to a certain extent, distant tsunami sources. Large slip concentrated in shallow patches was observed in recent ...

    Heterojunction band discontinuity control by ultrathin intralayers

    We present evidence that the band lineup at a semiconductor-semiconductor heterojunction interface can be changed and potentially controlled by an ultrathin metal intralayer. Synchrotron-radiation photoemissio...

    Dipole-Induced Changes of the Band Discontinuities at the SiO2-Si Interface

    We prove experimentally that the band lineup at the SiO2-Si interface can be modified by means of an intralayer. Hydrogen and cesium intralayers produce modifications of 0.5 and 0.25 eV in opposite directions. Po...
