Analysing bone regeneration using topological optimisation

Ingeniería e Investigación, 2005
The present article's object is to present the mathematical foundations of topological optimisation aimed at carrying out a study of bone regeneration. Bone structure can be economically adopted to different mechanical demands responding to topological ...

Study on Applications of Supply and Demand Theory of Microeconomics and Physics Field Theory to Central Place Theory [PDF]

This paper attempts to analyze “central place theory” of spatial economics based on “supply and demand theory” in microeconomics and “field theory” in physics, and also discuss their relationship.

Nearly critical superfluids in Keldysh-Schwinger formalism

Journal of High Energy Physics
We examine the effective theory of critical dynamics near superfluid phase transitions in the framework of the Keldysh-Schwinger formalism. We focus on the sector capturing the dynamics of the complex order parameter and the conserved current ...

Critical dynamics of superfluids

Journal of High Energy Physics
We use standard techniques of hydrodynamics to construct a relativistic effective field theory for the low energy dynamics of nearly critical superfluids.

The Holling Type II Population Model Subjected to Rapid Random Attacks of Predator

Journal of Applied Mathematics, 2018
We present the analysis of a mathematical model of the dynamics of interacting predator and prey populations with the Holling type random trophic function under the assumption of random time interval passage between predator attacks on prey. We propose a

Uncomputability and Undecidability in Economic Theory [PDF]

Economic theory, game theory and mathematical statistics have all increasingly become algorithmic sciences. Computable Economics, Algorithmic Game Theory ([28]) and Algorithmic Statistics ([13]) are frontier research subjects.

QED as the tensionless limit of the spinning string with contact interaction

Physics Letters B, 2015
QED with spinor matter is argued to correspond to the tensionless limit of spinning strings with contact interactions. The strings represent electric lines of force with charges at their ends.

Boomerang RG flows in M-theory with intermediate scaling

Journal of High Energy Physics, 2017
We construct novel RG flows of D=11 supergravity that asymptotically approach AdS 4 × S 7 in the UV with deformations that break spatial translations in the dual field theory.

Incoherent transport for phases that spontaneously break translations

Journal of High Energy Physics, 2018
We consider phases of matter at finite charge density which spontaneously break spatial translations. Without taking a hydrodynamic limit we identify a boost invariant incoherent current operator.
