Aerosols and clouds are key components of the marine atmosphere, impacting the Earth's radiative budget with a net cooling effect over the industrial era that counterbalances greenhouse gas warming, yet with an uncertain amplitude. Here we report recent ad ...

A new methodology for the satellite retrieval of cloud condensation nuclei (CCN) in shallow marine boundary layer clouds is developed and validated in this study. The methodology is based on retrieving cloud base drop concentrations (N d ) and updrafts (W ...

Precipitation falling over the coastal regions of Antarctica often experiences low-level sublimation within the dry katabatic layer. The amount of water that reaches the ground surface is thereby considerably reduced. This paper investigates the synoptic c ...

Precipitation is a process wherein a solid phase forms from a solution. Precipitation is at the heart of many industries producing pharmaceuticals, catalysts, ceramics, and nanoparticles. In addition to being a material synthesis route, precipitation has i ...

Aim: To study the specificity of cellular MRI based on superparamagnetic iron oxide particles (SPIOs), especially within the CNS. Materials & methods: A microglial cell line was engineered for the expression of a suicide gene, the receptor of diphtheria to ...

Solar concentration has the potential to decrease the cost associated with solar cells by replacing the receiving surface aperture with cheaper optics that concentrate light onto a smaller cell aperture. However a mechanical tracker has to be added to the ...

The recent years have highlighted the potential of photonic nanostructures to extend the capabilities of optical tweezers and to perform advanced optical manipulations. In this context, two-dimensional photonic crystal cavities have been regarded as promis ...

The processes driving current changes in Arctic atmospheric composition and climate are still uncertain. In particular the relative contributions of major source regions from the midlatitudes remain a matter of debate in the literature. The objectives of t ...

New generation of satellite navigation signals, such as AltBOC (Alternative Binary Offset Keying), CBOC (Composite Binary Offset Keying) and TMBOC (Time Multiplex Binary Offset Keying) bring enhancements in the tracking process, such as more signal power, ...

This paper presents three recursive Bayesian filtering approaches in phase shifting interferometry involving a piezoelectric device (PZT). The three approaches are extended Kalman filtering, unscented Kalman filtering, and particle filtering. These approac ...
