General Two-Stage Model-Based Three-Component Hybrid Compact Polarimetric SAR Decomposition Method

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Polarimetric decomposition is an effective way for synthetic aperture radar (SAR) data interpretation. As for hybrid compact polarimetric (HCP) SAR, there are mainly two different types of decomposition methods, including wave-dichotomy-theorem-based and

PAGaN I: Multi-Frequency Polarimetry of AGN Jets with KVN

, 2015
Active Galactic Nuclei (AGN) with bright radio jets offer the opportunity to study the structure of and physical conditions in relativistic outflows. For such studies, multi-frequency polarimetric very long baseline interferometric (VLBI) observations ...

All‐Fiber Microsensor of Polarization at Single‐Photon Level Aided by Deep Learning

Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.
Introducing a polarization sensor using scattering in a short optical fiber and deep learning. The breakthrough lies in sparse sampling of the scattered light and single‐photon sensitivity. The all‐fiber sensor achieves unprecedented accuracy, speed, resolution, and stability.

A compact and robust method for full Stokes spectropolarimetry

, 2012
We present an approach to spectropolarimetry which requires neither moving parts nor time dependent modulation, and which offers the prospect of achieving high sensitivity. The technique applies equally well, in principle, in the optical, UV or IR.

Perspectives on Systematic Cloud Microphysics Scheme Development With Machine Learning

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Cloud microphysics—the collection of processes that govern the small‐scale formation, evolution, and interactions of liquid droplets and ice crystals in clouds and precipitation—remains a major source of uncertainty in weather and climate models.

Optical and Radio Polarimetry of the M87 Jet at 0.2" Resolution

, 1999
We discuss optical (HST/WFPC2 F555W) and radio (15 GHz VLA) polarimetry observations of the M87 jet taken during 1994-1995. Many knot regions are very highly polarized ($\sim 40-50%$, approaching the theoretical maximum for optically thin synchrotron ...

A multi-wavelength pipeline for pulsar searches [PDF]

, 2019
Pulsar studies in the recent years have shown, more than others, to have benefited from a multi-wavelength approach. The INAF - Astronomical Observatory in Cagliari (INAF-OAC) is a growing facility with a young group devoted to pulsar and fast transients

Properties, mechanisms, and perspectives of ultrafast laser modifications in silicate glass volume

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Ultrafast laser irradiation of glass enables highly localized structural transformations within the material's bulk, unlocking diverse applications in photonics, data storage, and microfabrication. Here, we provide a concise yet comprehensive overview of the main types of femtosecond laser‐induced modifications in silica‐based glasses (Types I,
