Phase transitions in tumor growth VI: Epithelial–Mesenchymal transition
(Elsevier Science, 2018-06)
Herewith we discuss a network model of the epithelial–mesenchymal transition (EMT) based on our previous proposed framework. The EMT appears as a “first order” phase transition process, analogous to the transitions observed ...
The universal growth rate behavior and regime transition in adherent cell colonies
(Elsevier B.V., 2015-12-21)
In this work, we used five cell lineages, cultivated in vitro, to show they follow a common functional form to the growth rate: a sigmoidal curve, suggesting that competition and cooperation (usual mechanisms for systems ...
Polarization in the non-leptonic weak decays of spin-3/2 hyperons

Preliminary demographic analysis of a Toba population in transition in Northern Argentina
(University of Pennsylvania, 2007-12)
The Toba represent one of the many indigenous groups inhabiting the Gran Chaco of South America. They currently live in communities with different degrees of acculturation. We present here a preliminary data on fecundity ...
Chern-Simons diffusion rate across different phase transitions
(2016-05-24)
We investigate how the dimensionless ratio given by the Chern-Simons diffusion rate ΓCS divided by the product of the entropy density s and temperature T behaves across different kinds of phase transitions in the class of ...
Giant enhancement of phonon-assisted one-photon excited frequency upconversion in a Nd3+-doped tellurite glass
(2013-02-07)
Changing the sample's temperature from 200 K to 535 K, we observed 670-fold enhancement of a phonon-assisted upconversion emission at ≈754 nm obtained from a Nd3+-doped tellurite glass excited by 5 ns laser pulses at 805 ...

Bubble nucleation and growth in very strong cosmological phase transitions
(Elsevier Science, 2017-06)
Strongly first-order phase transitions, i.e., those with a large order parameter, are characterized by a considerable supercooling and high velocities of phase transition fronts. A very strong phase transition may have ...
Money supply and capital accumulation on the transition path revisited
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2010-02-22)
Fischer (1979) and Asako (1983) analyze the sign of the correlation between the growth rate of money and the rate of capital accumulation on the transition path. Both plug a CRRA utility (based on a Cobb-Douglas and a ...
