The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

Elevated mercury concentrations ([Hg]) were found in Alaskan murre (Uria spp.) eggs from the coastal embayment of Norton Sound relative to insular colonies in the northern Bering Sea-Bering Strait ...

Potassium-Argon dating is similar to Carbon 14 dating because it uses radioactive decay, measuring the rate of change from an ...

We investigate some qualitative properties for time-controlled switched systems consisting of several linear discrete-time subsystems. First, we study exponential stability of the switched system with ...

Nitrate loads and corresponding dual-isotope signatures were used to evaluate large scale N dynamics and trends in a river catchment with a strong anthropogenic gradient (forest conservation areas in ...

Some isotopes are unstable because an imbalance in their number of protons and neutrons gives them an excess of energy. It’s a little like a heavy object on a shelf or table.

Simon Fraser University (SFU) research is yielding new insights into one of the most perplexing properties of collagen. A ...

This letter proposes a frequency-domain stability analysis theory that provides the theoretical foundation for a unified and highly flexible framework for decentralized stability assessment of ...
