Colored visual stimuli evoke spectrally tuned neuronal responses across the central nervous system of zebrafish larvae

open access: yesBMC Biology, 2020
Background Visually guided behaviors such as optomotor and optokinetic responses, phototaxis, and prey capture are crucial for survival in zebrafish and become apparent after just a few days of development.

The association between conjunctival and scleral thickness and ocular surface ultraviolet autofluorescence

open access: yesScientific Reports, 2023
Ultraviolet autofluorescence (UVAF) imaging is used to visualise ocular surface changes due to sunlight exposure and so is considered to be a biomarker for UV damage.

Probing Globular Protein Self-Assembling Dynamics by Heterodyne Transient Grating Experiments

open access: yesApplied Sciences, 2019
In this work, we studied the propagation of ultrasonic waves of lysozyme solutions characterized by different degrees of aggregation and networking. The experimental investigation was performed by means of the transient grating (TG) spectroscopy as a ...

Fiber-Based SERS-Fluidic Polymeric Platforms for Improved Optical Analysis of Liquids

open access: yesBioengineering, 2023
Downsizing surface-enhanced Raman spectroscopy (SERS) within microfluidic devices has opened interesting perspectives for the development of low-cost and portable (bio)sensors for the optical analysis of liquid samples. Despite the research efforts, SERS-

Lens coloboma treated with lens surgery [PDF]

open access: yesBMJ Case Reports, 2015
A 5-year-old boy was referred to our clinic due to an abnormal visual acuity test at school. His corrected visual acuity was counting fingers in the left eye. A nasal side deficiency of the lens substituted by a membrane was found. Lens coloboma was diagnosed. After making a 3 mm limbal incision, the colobomatous lens was removed by anterior continuous

Strong Noise Rejection in VLC Links under Realistic Conditions through a Real-Time SDR Front-End

open access: yesSensors, 2023
One of the main challenges in the deployment of visible light communication (VLC) in realistic application fields, such as intelligent transportation systems (ITSs), is represented by the presence of large background noise levels on top of the optical ...
