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 ...
Defect-Induced Order-Order Phase Transition in Triblock Copolymer Thin Films
(American Chemical Society, 2021-02-08)
When a cylinder forming triblock copolymer thin film is exposed to supercritical carbon dioxide (scCO2), the system suffers an order-order phase transition from parallel (C∥) to perpendicularly oriented cylinders (C⊥). ...
Pressure-induced phase transitions in Zr-rich PbZr1-xTixO3 ceramics
(2001-08-20)
A Raman study of structural changes in the Zr-rich PbZr1-x TixO3 (PZT) system under hydrostatic pressures up to 5.0 GPa is presented. We observe that externally applied pressure induces several phase transitions in PZT ...

Investigation on dielectric response of PMN ceramics around paraelectric-ferroelectric diffuse phase transition
(Maney Publishing, 2009-11-01)
The dielectric properties of relaxor ferroelectric lead magnesium niobate Pb(Mg(1/3)Nb(2/3))O(3) (PMN) ceramics have been investigated. These studies were conducted taking into account the characterisations of the complex ...
Adiabatic quantum games and phase-transition-like behavior between optimal strategies
(2018-06-01)
In this paper we propose a game of a single qubit whose strategies can be implemented adiabatically. In addition, we show how to implement the strategies of a quantum game through controlled adiabatic evolutions, where we ...
A dynamical phase transition for a family of Hamiltonian mappings: A phenomenological investigation to obtain the critical exponents
(2015-05-31)
Abstract A dynamical phase transition from integrability to non-integrability for a family of 2-D Hamiltonian mappings whose angle, θ, diverges in the limit of vanishingly action, I, is characterised. The mappings are ...
Metal-insulator transition in Nd1-xEuxNiO 3 compounds
(2006-07-05)
Polycrystalline Nd1-xEuxNiO3 (0≤x≤0.5) compounds were synthesized in order to investigate the character of the metal-insulator (MI) phase transition in this series. Samples were prepared through the sol-gel route and ...
