Before 1980, Ikaria was self-sufficient, importing hardly anything and even milling its own wheat to make flour. Islanders made use of around 80 different kinds of wild greens and herbs in their diet, Buettner told Reader's Digest. Some have ten times the antioxidant levels of red wine, which are proven to reduce inflammation and lower blood pressure. The local diet also features a lot of beans and little meat or refined sugar.

We analyze in detail the effect of varying entropy degrees of freedom on low-scale leptogenesis models. As an archetypal model, we consider the triresonant leptogensis (TRL) scenario introduced recently by the authors, where the neutrino-Yukawa coupling matrix is dictated by an approximate Zn discrete symmetry (with n=3, 6).

The freeze-in mechanism has been shown to allow the simultaneous generation of cosmic dark matter and a viable matter-antimatter asymmetry in the Universe. When the underlying interactions are described by higher-dimensional, nonrenormalizable operators, the relevant freeze-in processes take place close to the highest considered cosmic temperatures.

Abstract We study in detail the dynamics of unstable two-level quantum systems by adopting the Bloch-sphere formalism of qubits. By employing the Bloch-vector representation for such unstable qubit systems, we identify a novel class of critical scenarios in which the so-called energy-level and decay-width vectors, E and Γ, are orthogonal to one another, and the parameter r=|Γ|/(2|E|) is less than 1.
