Learning Corrections for Hyperelastic Models From Data

Frontiers in Materials, 2019
Unveiling physical laws from data is seen as the ultimate sign of human intelligence. While there is a growing interest in this sense around the machine learning community, some recent works have attempted to simply substitute physical laws by data.

Violations of the weak cosmic censorship conjecture in the higher dimensional f(R) black holes with pressure

European Physical Journal C: Particles and Fields, 2020
We adopt the energy momentum relation of charged particles to study the thermodynamics laws and weak cosmic censorship conjecture of D-dimensional f(R) AdS black holes in different phase spaces by considering charged particle absorption.

Magnetic charges and Wald entropy

Journal of High Energy Physics, 2022
Using Wald’s formalism, we study the thermodynamics (first laws and Smarr formulae) of asymptotically-flat black holes, rings etc. in a higher-dimensional higher-rank generalization of the Einstein-Maxwell theory.

Eco-Dynamic Analysis of the Community Structure of Nekton in the Northern South China Sea

Fishes, 2023
The universal laws of thermodynamics in the process of ecosystem development have long been the common research focus of ecology and biophysics. Eco-exergy from thermodynamics is a popular theory in the study of ecosystem self-organization that has been ...

The laws of thermodynamics

BMJ, 1999
I was sitting on the end of the old man's bed listening to stories of his life. I was a medical student at the time. The odd thing, he had said, was that the world made no more sense to him then than it had when he was a boy. He had thought that things would become clearer with age. I remember the perplexity in his watery eyes.

Study of GSLT in Curvature-Matter Coupling Gravity

EPJ Web of Conferences, 2018
In this work, we study the first and generalized second laws of thermodynamics at the apparent horizon of homogeneous and isotropic universe model in the context of f (G, T) gravity (G and T represent the Gauss-Bonnet invariant and trace of the ...

Thermodynamics of non-local materials: extra fluxes and internal powers

, 2011
The most usual formulation of the Laws of Thermodynamics turns out to be suitable for local or simple materials, while for non-local systems there are two different ways: either modify this usual formulation by introducing suitable extra fluxes or ...

"A calorie is a calorie" violates the second law of thermodynamics

Nutrition Journal, 2004
The principle of "a calorie is a calorie," that weight change in hypocaloric diets is independent of macronutrient composition, is widely held in the popular and technical literature, and is frequently justified by appeal to the laws of thermodynamics ...

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

Advanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...
