Phase resetting and phase singularity of an insect circannual oscillator
Journal of Comparative Physiology A, 2007In circadian rhythms, the shape of the phase response curves (PRCs) depends on the strength of the resetting stimulus. Weak stimuli produce Type 1 PRCs with small phase shifts and a continuous transition between phase delays and advances, whereas strong stimuli produce Type 0 PRCs with large phase shifts and a distinct break point at the transition ...

SINGULAR INTEGRALS AND THE STATIONARY PHASE METHODS
Algebraic Approach to Differential Equations, 2010The paper is based on a course given in 2007 at an ICTP school in Alexandria, Egypt. It aims at introducing young scientists to methods to calculate asymptotic developments of singular integrals.

Phase Singularities and Termination of Spiral Wave Reentry
Journal of Cardiovascular Electrophysiology, 2002Phase Singularities and Termination of Reentry. Introduction: Recent defibrillation studies show that electric fields interact with reentrant activity in myocardial tissue through virtual electrode polarization (VEP). This study focuses on determining how VEP relates to the creation and survival of postshock phase singularities in cardiac ...

Superresolution at the singularities of phase images
Quantum Electronics, 2002Measurements performed with an Airyscan laser phase microscope showed the possibility of localisation of structural elements of a surface with a large gradient of the profile height and linear dimensions as small as 25 — 40 nm, which is 10 — 15 times lower than the Rayleigh criterion.

Entangled Tangles of Phase Singularities
Frontiers in Optics 2010/Laser Science XXVI, 2010We holographically measure entangled tangles of phase singularity lines in light generated via spontaneous parametric down-conversion. This type of entanglement is interesting because it is between topological features that extend over finite, macroscopic, isolated volumes.

Phase transitions in ferromagnets and singularities
Reports on Mathematical Physics, 1985The paper is devoted to the phenomenological investigation of the critical phenomena in ferromagnets by means of the modern theory of singularities. In order to take into account the hysteresis phenomena the authors postulate that the set of thermodynamical parameters (M,T) (magnetization and temperature) corresponding to ...

Generic Diffusion of Phase Singularities
CLEO: 2014, 2014We find generic diffusion of phase singularities in microwave speckle patterns as the frequency is scanned and in numerical simulations in the time domain. These results give the photon diffusion coefficient through the random medium.

Analyticity, Singularity and Phase Transitions
2004There are various instances in which the construction of the Gibbs distributions can be performed in great detail, almost completely explicitly, allowing us to answer satisfactorily questions concerning, for instance, mixing rates of Gibbs states and smoothness of their dependence on the potential.
