Multiwavelength observations of blazars [PDF]

open access: yes, 2016
The INTEGRAL mission has played a major role in blazar science, thanks to its sensitive coverage of a spectral region (3-100 keV) that is critical for this type of sources, to its flexibility of scheduling and to the large field of view of its cameras. A

Observations on the observer pattern [PDF]

open access: yesProceedings of the 17th Conference on Pattern Languages of Programs, 2010
A group of students who should have been familiar with basic design principles and MVC all failed to implement the Observer design pattern correctly while at the same time violating several design principles. This paper discusses what went wrong and why it probably went wrong.

Plastic Plants: The Role of Water Hyacinths in Plastic Transport in Tropical Rivers

open access: yesFrontiers in Environmental Science, 2021
Recent studies suggest that water hyacinths can influence the transport of macroplastics in freshwater ecosystems at tropical latitudes. Forming large patches of several meters at the water surface, water hyacinths can entrain and aggregate large amounts
