BACKGROUND The International Space Station (ISS) represents a unique biotope for the human crew but also for introduced microorganisms. Microbes experience selective pressures such as microgravity, desiccation, poor nutrient-availability due to cleaning, and an increased radiation level. We hypothesized that the microbial community inside the ISS is modified by adapting to these stresses. For t...

The Mt. Rudnaya MSS-ISS (monosulfide and intermediate solid solution) fine-grained ores from a NE termination of Norilsk 1 deposit were analyzed using combination X-ray computed micro tomography, spectral tomography scanning electron microscopy to achieve both, 2D 3D data. consist ISS composed tiny lamellar intergrowths cubanite chalcopyrite solutions, which form up 4-mm distinct globules surro...

This paper aims to discuss and analyze the potentialities of Recurrent Neural Networks (RNN) in control design applications. The main families RNN are considered, namely Nonlinear AutoRegressive eXogenous, (NNARX), Echo State (ESN), Long Short Term Memory (LSTM), Gated Units (GRU). goal is twofold. Firstly, survey recent results concerning training that enjoy Input-to-State Stability (ISS) Incr...

BACKGROUND The built environment of the International Space Station (ISS) is a highly specialized space in terms of both physical characteristics and habitation requirements. It is unique with respect to conditions of microgravity, exposure to space radiation, and increased carbon dioxide concentrations. Additionally, astronauts inhabit a large proportion of this environment. The microbial comp...

This paper presents the results of application of innovative knowledge-based multi-agent technology for scheduling of flight program, cargo flow, fuel, water, and other resources of International Space Station (ISS). The developed system aims creating solid information space for scientists, responsible for ISS life activity and supply with various resources and provides intelligent scheduling c...

The input-to-state stability (ISS) problem is studied for switched systems with infinite subsystems. By the method of multiple Lyapunov function, a sufficient ISS condition is given based on a quantitative relation of the input and the values of the Lyapunov functions of the subsystems before and after the switching instants. In terms of the average dwell-time of the switching laws, some suffic...

Methodology: The Injury severity Score (ISS) is the default world standard for assessing the severity of multiple injuries. ISS is a mathematical fit to empirical field data. It is demonstrated that ISS is proportional to the Gibbs/Shannon Entropy. A new Entropy measure of morbidity from blunt force trauma including co-morbidities is derived based on the von Neumann Entropy, called the Abbrevia...

"To know that we know what we know, and that we do not know what we do not know, that is true knowledge." (Thoreau) There still is a lot we don't know yet about the environmental, health and safety impact of nanomaterials, but at least scientists are making progress in identifying the gaps – the 'known unknowns' as they call it. A group of researchers at the Technical University of Denmark (DTU...
