Exploratory Research on Radioisotope Thermoelectric Generators for Deep Space Missions
To support the development of a Radioisotope Power Source (RPS) for exploration missions into deep space based on 241Am, the European Commission’s Joint Research Centre (JRC) has recently launched an exploratory research project, scheduled for a period ...

A characterization of Dynkin elements [PDF]
We give a characterization of the Dynkin elements of a simple Lie algebra. Namely, we prove that one-half of a Dynkin element is the unique point of minimal length in its N-region. In type A_n this translates into a statement about the regions determined

Transposable elements are known by many names, including 'transposons', 'interspersed repeats', 'selfish genetic elements', 'jumping genes', and 'parasitic DNA', but here we will refer to them simply as transposable elements. Many biologists will have heard of transposable elements and their ability to transpose (change position) within the genome. But

A smart friction control strategy enabled by CO2 absorption and desorption
Intelligent control of friction is an attractive but challenging topic and it has rarely been investigated for full size engineering applications. In this work, it is instigated if it would be possible to adjust friction by controlling viscosity in a ...

CAD Representation of the Mullins Effect from the SEGE 80 Flexible Coupling Model
A Mullins simulation was conducted to analyze the effects of loading and unloading of a flexible-type SEGE coupling with a nominal torque of Tnom=80 Nm and maximum torque of Tmax=120 Nm.
