Landau theory for the Mpemba effect through phase transitions

Communications Physics, 2022
The Mpemba effect describes the situation in which a hot system cools faster than an identical copy at a colder temperature. Here, the authors present a theoretical model for the Mpemba effect through a second-order phase transition and showcase how this

Phase transitions in single neurons and neural populations: Critical slowing, anesthesia, and sleep cycles

, 2010
The firing of an action potential by a biological neuron represents a dramatic transition from small-scale linear stochastics (subthreshold voltage fluctuations) to gross-scale nonlinear dynamics (birth of a 1-ms voltage spike). In populations of neurons

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Phase Transitions in Finite Systems [PDF]

, 2005
This paper examines the apparent paradox in the fact that all successful theoretical treatments of phase transitions require an infinite system, yet they are clearly seen to occur in finite systems in the real world.

The kinetic-theory for dilute solid liquid 2-phase flow

, 1991
On the basis of a brief review of the continuum theory for macroscopic descriptions and the kinetic theory for microscopic descriptions in solid/liquid two-phase flows, some suggestions are presented, i.e.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Dirac Theory in Noncommutative Phase Spaces

Physics
Based on the position and momentum of noncommutative relations with a noncanonical map, we study the Dirac equation and analyze its parity and time reversal symmetries in a noncommutative phase space.

Discrete Quadratic-Phase Fourier Transform: Theory and Convolution Structures

Entropy, 2022
The discrete Fourier transform is considered as one of the most powerful tools in digital signal processing, which enable us to find the spectrum of finite-duration signals.

Emergence and Reduction Combined in Phase Transitions [PDF]

, 2011
In another paper (Butterfield 2011), one of us argued that emergence and reduction are compatible, and presented four examples illustrating both. The main purpose of this paper is to develop this position for the example of phase transitions.
