A flux of weakly interacting neutral particles incident on the Earth would produce occasional nuclear-recoil events in any material. These could be detected as scintillation or ionization pulses in suitable target materials. Expected rates are in the range 1-10(-4) events kg(-1) d(-1). These must be distinguished from much higher rates due to backgrounds from gamma and beta background, even in ...

The sailing tracks of single otter trawl vessels were simulated using cubic hermite spline (cHs) interpolation method based on the automatic identification system (AIS) data of 6 sampled vessels that were fishing in the Zhoushan fishing grounds after the close of the fishing season from September 2012 to January 2013.  The vessels’ status (i.e. whether the vessels were fishing or not) were dete...

Ballast as a part of the railway system plays an important role in the operation of the railways and also has a great impact on repair and maintenance activities. Hence most of the repair and maintenance activities in traditional railway systems are due to the defections in the ballast layer and therefore most of the maintenance budget is spent on repairing these defects. These repair and maint...

Neuronal migration is a fundamental process of mammalian brain development. In migrating neurons, the nuclear membrane protein Nesprin-2 has been shown to serve as an adaptor pull nucleus along microtubule tracks. Current evidence that binds both minus-end-directed motor dynein well plus-end-directed kinesin. However, translocation neuronal long thought be primarily driven by motors. Intriguing...
