Survival Across the Fitness-Stress Continuum Under the Ecological Stress Theory of Aging: Caloric Restriction and Ionizing Radiation

open access: goldDose-Response, 2010
Free living organisms typically occur in harsh environments challenged by abiotic stresses of varying intensities. Taking ionizing radiation and caloric restriction as examples, environmental variation from benign to extreme gives a fitness-stress ...

Carnot and the Archetype of Waterfalls [PDF]

open access: yesEntropy
Carnot treats Heat as a Force of Nature, with its typical fundamental characteristics of intensity and thermal tension (temperature and temperature difference), extension (amount of heat, i.e., caloric), and power.

Carnot Theorem Revisited: A Critical Perspective [PDF]

open access: yesEntropy
After a brief review of Carnot’s everlasting contributions to the foundations of thermodynamics, we critically examine the consequences of the Carnot theorem, which leaves behind some lingering questions and confusion that persist even today. What is the

Caloric effects around phase transitions in magnetic materials described by ab initio theory: The electronic glue and fluctuating local moments [PDF]

open access: greenJournal of Applied Physics, 2020
We describe magneto-, baro-, and elastocaloric effects (MCEs, BCEs, and eCEs) in materials, which possess both discontinuous (first-order) and continuous (second-order) magnetic phase transitions.

Spin caloric transport from density-functional theory [PDF]

open access: bronzeJournal of Physics D: Applied Physics, 2018
Spin caloric transport refers to the coupling of heat with spin transport. Its applications primarily concern the generation of spin currents and control of magnetisation by temperature gradients for information technology, known by the synonym spin ...

Compression of morbidity by interventions that steepen the survival curve [PDF]

open access: yesNature Communications
Longevity research aims to extend the healthspan while minimizing the duration of disability and morbidity, known as the sickspan. Most longevity interventions in model organisms extend healthspan, but it is not known whether they compress sickspan ...
