Below‐Cloud CCN Concentrations Provide Better Constraints on the Twomey Effect Than Aerosol Optical Properties

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The primary uncertainty in anthropogenic climate forcing arises from a limited understanding of aerosol effects on cloud albedo, which in combination with other effects, is termed the radiative forcing from aerosol‐cloud interactions (RFaci).

Linear polarization sensitivity of SeGA detectors [PDF]

open access: yes, 2006
Parity is a key observable in nuclear spectroscopy. Linear polarization measurements of $\gamma$-rays are a probe to access the parities of energy levels.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

A single-channel polarimeter [PDF]

open access: yesSymposium - International Astronomical Union, 1986
We have developed a single-channel photopolarimeter to measure polarization ∼1%, with an accuracy of 0.1% or so. Laboratory tests show that the performance of the instrument is as per the requirements.

Over seven decades of solar microwave data obtained with Toyokawa and Nobeyama Radio Polarimeters

open access: yesGeoscience Data Journal, 2023
Monitoring observations of solar microwave fluxes and their polarization began in Japan during the 1950s at Toyokawa and Mitaka. At present (April 2022), monitoring observations continues with the Nobeyama Radio Polarimeters (NoRP) at the Nobeyama campus

Fast and optimal broad-band Stokes/Mueller polarimeter design by the use of a genetic algorithm

open access: yes, 2010
A fast multichannel Stokes/Mueller polarimeter with no mechanically moving parts has been designed to have close to optimal performance from 430-2000 nm by applying a genetic algorithm.

Beam energy measurement at linear colliders using spin precession [PDF]

open access: yes, 2003
Linear collider designs foresee some bends of about 5-10 mrad. The spin precession angle of one TeV electrons on 10 mrad bend is 23.2 rad and it changes proportional to the energy. Measurement of the spin direction using Compton scattering of laser light

Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

open access: yesAdvanced Functional Materials, Volume 36, Issue 35, 30 April 2026.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

A novel comparison of Møller and Compton electron-beam polarimeters

open access: yesPhysics Letters B, 2017
We have performed a novel comparison between electron-beam polarimeters based on Møller and Compton scattering. A sequence of electron-beam polarization measurements were performed at low beam currents (

Development of Laterally Graded X‐Ray Multilayer Optics

open access: yesAdvanced Materials Technologies, Volume 11, Issue 8, 17 April 2026.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...
