Article Synopsis
  • Researchers combined a high-speed external display (360 fps) with an adaptive optics scanning laser ophthalmoscope (AOSLO) to enhance human foveal imaging for psychophysics experiments.
  • A custom pupil relay was developed for precise stimulus viewing and was validated to correct refractive errors while achieving a high Strehl ratio, ensuring image clarity.
  • The system achieved excellent eye-tracking capabilities, allowing for accurate localization of visual stimuli and capturing detailed images of the human central fovea, while overcoming previous limitations in temporal and spatial resolution.

Article Synopsis
  • * The Ne/Nc ratio varies due to ecological and evolutionary factors, influencing conservation strategies, and different types of effective population sizes must be considered to grasp their implications.
  • * Despite technological advancements in marine species documentation, predicting the Ne/Nc ratio remains challenging, highlighting the need for more research to effectively manage genetic diversity and population viability in these fish populations.

Objective: In share wave elastography (SWE), the aim is to measure the velocity of shear waves, however unwanted compression waves and bulk tissue motion pose challenges in evaluating tissue stiffness. Conventional approaches often struggle to discriminate between shear and compression waves, leading to inaccurate shear wave speed (SWS) estimation. In this study, we propose a novel approach known as the integrated difference autocorrelation (IDA) estimator to accurately estimate reverberant SWS in the presence of compression waves and noise.

We report the experimental demonstration of an optical differentiation wavefront sensor (ODWS) based on binary pixelated linear and nonlinear amplitude filtering in the far-field. We trained and tested a convolutional neural network that reconstructs the spatial phase map from nonlinear-filter-based ODWS data for which an analytic reconstruction algorithm is not available. It shows accurate zonal retrieval over different magnitudes of wavefronts and on randomly shaped wavefronts.

Background: Allergen immunotherapy (AIT) is the only disease-modifying treatment for allergic disorders. We have recently discovered that allergen-specific memory B cells (Bmem) are phenotypically altered after 4 months of sublingual AIT for ryegrass pollen allergy. Whether these effects are shared with subcutaneous allergen immunotherapy (SCIT) and affect the epitope specificity of Bmem remain unknown.
