Evolution of annual rainfall irregularity in the southwest of the Iberian Peninsula
(Springer Nature, 2011)
The areas of the Iberian Peninsula with Mediterranean climate are characterised by rainfall irregularity. Standard statistical estimation methods provide a limited insight of all the dimensions of such irregularity. Based ...

Radiological impact of naturally occurring radionuclides in bottled water
(Elsevier, 2021-12)
Consumption of bottled water is increasing year after year in Europe. Due to the local geology from where the water is extracted; bottled water could be enhanced with radionuclides. This study focuses on the activity ...

All noncontextuality inequalities for the n -cycle scenario
(American Physical Society, 2013-08-21)
The problem of separating classical from quantum correlations is, in general, intractable and has been solved explicitly only in a few cases. In particular, known methods cannot provide general solutions for an arbitrary ...

A comparison of two micro-beam X-ray emission techniques for actinide elemental distribution in microscopic particles originating from the hydrogen bombs involved in the Palomares (Spain) and Thule (Greenland) accidents
(Elsevier, 2010)
In order to validate and to gain confidence in two micro-beam techniques: particle induced X-ray emission with nuclear microprobe technique (μ-PIXE) and synchrotron radiation induced X-ray fluorescence in a confocal ...

Geographical, seasonal, and depth variation in sinking particle speeds in the North Atlantic
(AGU Publications, 2016-08)
Particle sinking velocity is considered to bea controlling factor for carbon transport to the deep sea and thus carbon sequestration in the oceans. The velocities of the material exported to depth are considered to be high ...

Revisiting five decades of 234Th data: a comprehensive global oceanic compilation
(Copernicus Publications, 2022)
We present here a global oceanic compilation of 234Th measurements that collects results from researchers and laboratories over a period exceeding 50 years. The origin of the 234Th sampling in the ocean goes back to 1967, ...

Effective geometric phases and topological transitions in SO(3) and SU(2) rotations
(IOP Publishing, 2016-03-24)
We address the development of geometric phases in classical and quantum magnetic moments (spin-1/2) precessing in an external magnetic field. We show that nonadiabatic dynamics lead to a topological phase transition ...

Quantum clock synchronization with a single qudit
(Nature Research, 2015-01-23)
Clock synchronization for nonfaulty processes in multiprocess networks is indispensable for a variety of technologies. A reliable system must be able to resynchronize the nonfaulty processes upon some components failing ...
