Aberration-free calibration for 3D single molecule localization microscopy
We propose a straightforward sample-based technique to calibrate the axial detection in 3D single molecule localization microscopy (SMLM). Using microspheres coated with fluorescent molecules, the calibration curves of PSF-shaping- or intensity-based ...

Aberration-corrected time aperture of an electro-optic time lens
Recently, there has been renewed interest in electro-optic time lenses due to their favorable properties for quantum photonic applications. Here, we propose a new analytical approach to estimate the chirp rate of a time lens implemented using an electro ...

Effect of the Gravitational Aberration on the Earth Gravity Field [PDF]
Discussing the problem of the external gravitational potential of the rotating Earth, we have to consider the fundamental postulate of the finite speed of the propagation of gravitation.

Permanent Maxillary First Molar with Two Rooted Anatomy: A Rare Occurrence [PDF]
The basis of successful endodontic therapy resides on sound and thorough knowledge of the root canal anatomy, its variations and the clinical skills. The importance of the knowledge of the anatomy of root canals cannot be overemphasized. Unusual root and

A Forward Model for Estimating Phase Aberration in Ultrasound Imaging
In this paper, we first proposed that the phase aberration profile estimated by cross-correlation methods is the sum of the true phase aberration profile and the geometric delay change due to the shifting of the focus point caused by the true phase ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Misalignment induced aberration off-axis optical system
Through introducing transformed pupil vector and shifted center of aberration fields vector into the nodal aberration expansions of an axially symmetric optical system, the aberration expression in third order of an off-axis optical system and ...
