The Biomass Power Program of the US Department of Energy (DOE) has as a major goal the development of cost-competitive technologies for the production of power from renewable biomass crops. The gasification of biomass provides the potential to meet his goal by efficiently and economically producing a renewable source of a clean gaseous fuel suitable for use in high efficiency gas turbines. This paper discusses the development and first commercial demonstration of the Battelle high-throughput gasification process for power generation systems. Projected process economics are presented along with a description of current experimental operations coupling a gas turbine power generation system to the research scale gasifier and the process scaleup activities in Burlington, Vermont.

Advanced Virgo is an interferometer for the detection of gravitational waves at the European Gravitational Observatory in Italy. Along with the two Advanced LIGO interferometers in the US, Advanced Virgo is being used to collect data from astrophysical sources such as compact binary coalescences and is currently running the third observational period, collecting gravitational wave event candidates at a rate of more than once per week. Data from the interferometer are processed by running search pipelines for several expected signals, from coalescing compact binaries to continuous waves and burst events. Furthermore, detector characterisation studies are run. Some of the processing needs to be done with low latency, to be able to provide triggers for other observatories and make multi-messenger observations possible. Deep searches are run offline on external computing centres. Thus, data needs also to be reliably and promptly distributed from the EGO site to computer centres in Europe and the US for further analysis and archival storage. Two of the defining characteristics of Virgo computing are the heterogeneity of the activities and the need to interoperate with LIGO. A very wide array of analysis pipelines differing in scientific target, implementation details and running environment assumptions have to be allowed to run ubiquitously and uniformly on dedicated resources and, in perspective, on heterogeneous infrastructures. The current status, possible strategies and outlook of Virgo computing are discussed.

Conflicts such as Nagorno-Karabakh, the Donbas, Libya, Syria and Yemen have shown that even in such different scenarios, the diffusion of the key advances that were at the heart of the Revolution in Military Affairs is a fact. Moreover, most of these advances are so well established that they are now in daily use not only by many states, but also by their proxies and even by transnational terrorist and criminal groups. This phenomenon is intimately associated with the erosion of US military superiority, a country that is seeing how the People's Republic of China or the Russian Federation, but also North Korea or Iran, are capable of challenging the former superpower. In this scenario, aware of the need to compensate for the advances made by the other players, the US has launched a series of initiatives, such as the Third Offset Strategy, aimed at achieving new technological and arms developments that could lead to a new Revolution in Military Affairs or, perhaps, a full-fledged Military Revolution. In this complex context, in which conflicts fought with inherited means will converge with new weapons, systems and platforms and with the entry into service of developments that we cannot yet imagine, the Spanish defence industry will have to struggle to survive, knowing that its main customer - the Spanish Ministry of Defence - is in a very delicate situation in terms of facing this new stage.
