Comunicación científica en Colombia: todo un reto

Chasqui, 2015
Hace doscientos años se inició en Colombia la comunicación de la ciencia. En los últimos treinta años ha tenido un gran impulso pues el 0.7 por ciento estuvo dedicado a ellas. Existe una política científica y tecnológica que ha permitido la proliferación

The fog that was not [PDF]

Nature, 2001
In macroscopic systems, we can use classical mechanics to describe an object’s motion with precise knowledge of where the object is and where it is going. But the microscopic world is governed by the laws of quantum mechanics, which rob us of this precision.

Three brown frog species in Denmark have different abilities to colonise new ponds [PDF]

Herpetozoa
For 29 consecutive years, the populations of three species of brown frogs, Rana arvalis, R. dalmatina and R. temporaria, were monitored in an open area in South Zealand, Denmark, with no direct influence of agriculture.

Improving Fog Computing Performance via Fog-2-Fog Collaboration [PDF]

Future Gener. Comput. Syst., 2019
In the Internet of Things (IoT) era, a large volume of data is continuously emitted from a plethora of connected devices. The current network paradigm, which relies on centralized data centers (aka Cloudcomputing), has become inefficient to respond to IoT latency concern. To address this concern, fog computing allows data processing and storage \close"

Mechanistic investigations of the formation of multifunctional products from the multi-generation ⚫OH oxidation of styrene [PDF]

Atmospheric Chemistry and Physics
Styrene is a highly reactive aromatic hydrocarbon that has been identified as a key secondary organic aerosol (SOA) precursor. Recent laboratory chamber experiments have identified C7 and C8 series compounds as the main components of SOA in the ...

A Locally Smoothed Terrain‐Following Vertical Coordinate to Improve the Simulation of Fog and Low Stratus in Numerical Weather Prediction Models

Journal of Advances in Modeling Earth Systems, 2021
The correct simulation of fog and low stratus (FLS) is a difficult task for numerical weather prediction (NWP) models. The Swiss Plateau experiences many days with FLS in winter. Most NWP models employ terrain‐following vertical coordinates.
