6 Recent studies attribute land double-frequency (DF) microseism observations to deep7 water generation. Here we show that near-coastal generation is generally the dominant 8 source region. This determination is based on observations at land and ocean seismic 9 stations, buoys, gravity wave hindcasts, and on beamforming results from continental 10 seismic arrays. Interactions between opposing o...

At present the Frascati Φ-factory DAΦNE is operating in multibunch regime with stored currents in the range of 0.5-1 A in both e+ and erings. A longitudinal bunch-bybunch feedback system has been operating in each DAΦNE main ring since the beginning of the machine commissioning. The transverse bunch-by-bunch feedback system working in the vertical plane has been implemented last year in both ri...

Biodiversity loss is a global phenomenon (1), with Woinarski et al. (2) providing a sobering review of the demise of the Australian native terrestrial mammal fauna. The authors’ focus is on the loss of >10% of endemic terrestrial native mammal fauna since European settlement in 1788. The extent of mammal loss is highlighted by the contrast with mainland North America, with just one mammal speci...

In the companion paper (Towards a “sophisticated” model of belief dynamics. Part I), a general framework for realistic modelling of instantaneous states of belief and of the operations involving them was presented and motivated. In this paper, the framework is applied to the case of belief revision. A model of belief revision shall be obtained which, firstly, recovers the Gärdenfors postulates ...

A time revolved spectroscopic study of the emission phases occurring throughout a nanosecond pulsed discharge in water is presented. Discharged are ignited in deionized water via a submerged pin-t-plane electrode configuration by application of 24kV pulses with a rise time of 4ns and a duration of 10ns. Optical emission spectroscopy of the plasma radiation is performed, revealing a very complex...

Patterns of genetic connectivity are increasingly considered in the design of marine protected areas (MPAs) in both shallow and deep water. In the New Zealand Exclusive Economic Zone (EEZ), deep-sea communities at upper bathyal depths (<2000 m) are vulnerable to anthropogenic disturbance from fishing and potential mining operations. Currently, patterns of genetic connectivity among deep-sea pop...

The Adriatic coast of Northeast Italy is one the representative areas holding high ecological value in Mediterranean. In this research, we have monitored environmental change coastal wetland ten studied sites that covered all Ramsar and most natural reserves from 1984 to 2016. results show environment has been changing associated with a multitude influential factors, including economic developm...

Abstract The East Antarctic Ice Sheet stores a vast amount of freshwater, which makes it the single largest potential contributor to future sea-level rise. However, lack well-constrained geological records past ice sheet changes impedes model validation, hampers mass balance estimates, and inhibits examination loss mechanisms. Here we identify rapid ice-sheet thinning in coastal Dronning Maud L...

Projections of changes in Antarctic Ice Sheet (AIS) surface mass balance indicate a negative contribution to sea level becauseof theexpected increase inprecipitationdue to thehigher moisture holding capacity of warmer air1. Observations over the past decades, however, are unable to constrain the relation between temperature and accumulation changes because both are dominated by strong natural v...
