Revisiting PSF models: Unifying framework and high‐performance implementation

open access: yesJournal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Semiparametric regression for circular response with application in ecology

open access: yesScandinavian Journal of Statistics, EarlyView.
ABSTRACT A regression model for a circular response variable depending on a linear or a circular predictor is presented in this paper. The conditional density belongs to a parametric flexible family that allows for asymmetry and varying peakedness around the modal direction.

On goodness‐of‐fit testing for self‐exciting point processes

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract Despite the wide usage of parametric point processes in theory and applications, a sound goodness‐of‐fit procedure to test whether a given parametric model is appropriate for data coming from a self‐exciting point process has been missing in the literature.

Spontaneous Ca2+ signals in the developing mammalian cochlea of live mice under different anaesthetic regimes

open access: yesExperimental Physiology, EarlyView.
Abstract The pre‐hearing mouse cochlea undergoes critical periods of spontaneous Ca2+‐dependent activity that spreads across non‐sensory supporting cells and inner hair cells (IHCs). These signals have been shown to regulate not only the refinement of neural circuits along the auditory pathway towards functional maturity, but also the maturation of the

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

An expansion formula for the H-function of two variables

open access: yesRevista Técnica de la Facultad de Ingeniería, 2011
The object of this note is to evaluate an integral associated with Bessel polynomials and the H-function of two variables and to apply it in proving an expansion formula for the H-function of two variables in series of product of the Bessel polynomials ...
