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

Dose-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 ...

Frustrated magnetism and caloric effects in Mn-based antiperovskite Nitrides : Ab Initio theory [PDF]

, 2017
We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised density functional theory to compare the response of the geometrically ...

Caloric Curve for Finite Nuclei in Thomas-Fermi Theory [PDF]

, 1997
In a finite temperature Thomas-Fermi theory with realistic nuclear interactions, we construct caloric curves for finite nuclei enclosed in a sphere of about $4 - 8$ times the normal nuclear volume.

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

, 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.

Carnot and the Archetype of Waterfalls [PDF]

Entropy
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.

Vestibular Atelectasis: A Narrative Review and Our Experience [PDF]

Audiology Research
Vestibular atelectasis (VA) is a rare clinical entity characterized by a collapse of the endolymphatic space resulting in vestibular loss with the possible onset of positional and/or sound/pressure-induced vertigo.

Carnot Theorem Revisited: A Critical Perspective [PDF]

Entropy
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

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

Nature 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 ...

Random Transitions of a Binary Star in the Canonical Ensemble [PDF]

Entropy
After reviewing the peculiar thermodynamics and statistical mechanics of self-gravitating systems, we consider the case of a “binary star” consisting of two particles of size a in gravitational interaction in a box of radius R.

Milankovitch, the father of paleoclimate modeling [PDF]

Climate of the Past, 2021
The history of the long-term variations in the astronomical elements used in paleoclimate research shows that, contrary to what might be thought, Milutin Milankovitch is not the father of the astronomical theory but he is definitely the father of ...
