Abstract Libraries of inherent optical properties (IOPs) of microplastics are sparse, yet they are essential for the development of optical techniques to detect and quantify microplastics in the ocean. In this study, we describe our results and techn

We exhibit a proof-of-concept laboratory study for inversion of the partial Mueller scattering matrix of hydrosols from polarimetric observations across a smooth Fresnel boundary. The method is able to derive the 9 Mueller matrix elements relating to

We describe the application of a Neural Network (NN) previously developed by us, to the detection and tracking, of Karenia brevis Harmful Algal Blooms (KB HABs) that plague the coasts of the West Florida Shelf (WFS) using Visible Infrared Imaging Rad

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has become the procedure of choice to obtain samples from pancreatic lesions. However, it still has limitations affecting its diagnostic yield. The endoscopic ultrasound-guided fine-needle

Background The course of hypersensitivity pneumonitis (HP) is characterized by variable patterns of disease progression. Refractory HP is defined as poor or lack of response to different modalities of treatment with worsening of the functional status

We examine the potential for ocean color (OC) retrievals using a neural network (NN) technique recently developed by us to make up for the lack of a 678 nm fluorescence band on VIIRS, previously available on MODIS and important for Karenia brevis har
