A novel optical model of the experimental transmission spectra of nanocomposite PVC-PS hybrid thin films doped with silica nanoparticles. [PDF]
Heliyon, 2020 We propose a novel derived optical model fitted to the experimental transmittance of PVC-PS hybrid thin films doped with Silica nanoparticles. The films are synthesized using a simple dip-coating method.

A new optical model for photomultiplier tubes [PDF]
The European Physical Journal C, 2022 It is critical to construct an accurate optical model of photomultiplier tubes (PMTs) in many applications to describe the angular and spectral responses of the photon detection efficiency (PDE) of the PMTs in their working media.

A complete optical model for liquid-scintillator detectors [PDF]
, 2020 Liquid scintillator (LS) is widely used in various neutrino oscillation experiments, in particular, the reactor neutrino experiments. The complex absorption and re-emission processes of optical photons are known to be an important source of the non ...

Recent developments for the optical model of nuclei [PDF]
Progress in Particle and Nuclear Physics, 2018 A brief overview of various approaches to the optical-model description of nuclei is presented. A survey of some of the formal aspects is given which links the Feshbach formulation for either the hole or particle Green's function to the time-ordered ...

The Surprising Effectiveness of Diffusion Models for Optical Flow and Monocular Depth Estimation [PDF]
Neural Information Processing Systems, 2023 Denoising diffusion probabilistic models have transformed image generation with their impressive fidelity and diversity. We show that they also excel in estimating optical flow and monocular depth, surprisingly, without task-specific architectures and ...

Novel applications of the dispersive optical model [PDF]
, 2016 A review of recent developments of the dispersive optical model (DOM) is presented. Starting from the original work of Mahaux and Sartor, several necessary steps are developed and illustrated which increase the scope of the DOM allowing its ...

PWC-Net: CNNs for Optical Flow Using Pyramid, Warping, and Cost Volume [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 We present a compact but effective CNN model for optical flow, called PWC-Net. PWC-Net has been designed according to simple and well-established principles: pyramidal processing, warping, and the use of a cost volume. Cast in a learnable feature pyramid,
