Gait muscle activity during walking on an inclined icy surface.

The objective of this study was to explain the contribution of lower extremity muscle activity to gait kinetic and kinematic adaptations for maintaining gait dynamic balance when walking on an inclined icy surface and the biomechanical mechanisms used to counteract slip risk. A two-way factorial experimental design was applied. The two independent variables were the walkway surface (ice and tre...

Dynamics in an Evolving Partnership

Repeat players’ ability to cooperate in equilibrium depends on how long they expect their relationship to last (“stability”), which itself may change over time. This paper develops a theory of endogenous stability and dynamic performance in partnerships with evolving payoffs, in the context of a simple repeated Prisoners’ Dilemma with voluntary entry and exit. More stable partnerships are more ...

Geology of the Icy Satellites

In the last 25 years, the explorations of the Voyager and Galileo missions have resulted in an entirely new view of the icy worlds orbiting the giant outer planets. These objects show a huge diversity in their characteristics, resulting from their formation histories, internal processes and interactions with their space environments. This paper will review the current state of knowledge about t...

Microbial Habitability of Icy Worlds

F or most of Earth’s history, life was microscopic and, even today, microorganisms dominate the planet. Hence, we believe that, if life exists beyond Earth, it likely started as microorganisms and may remain at this stage. Much of contemporary astrobiological research focuses on the metabolic potential of microorganisms and their ability to inhabit extreme environments. The search for life beyo...

Lanthanide-tagged proteins--an illuminating partnership.

Lanthanide-tagged proteins are valuable for exploiting the unique properties of Ln ions for investigating protein structure, function, and dynamics. Introduction of the Ln into the target is accomplished via chemical modification with synthetic lanthanide-chelating prosthetic groups or by coexpression with peptide-based binding tags. Complexed Ln-tags offer a heavy-atom site for solving the pha...
