The Formation of Cirrus‐Like Water and Carbon Dioxide Ice Clouds in the Venusian Upper Haze Region

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The upper haze region of the Venusian atmosphere (∼70–100 km) experiences localized cooling, probably due to gravity waves, creating transient cold pockets. Water ice clouds may form in these cold pockets when sulfuric acid droplets undergo hygroscopic growth and subsequent freezing.

An Overview of X-Ray Polarimetry of Astronomical Sources

Galaxies, 2018
We review the history of astronomical X-ray polarimetry based on the author’s perspective, beginning with early sounding-rocket experiments by Robert Novick at Columbia University and his team, of which the author was a member.

Dalle de verre Windows From the Cathedral of Rio de Janeiro: Artistic Technique and Glass Conservation

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
Glass samples from the Rio de Janeiro Cathedral (Brazil) were evaluated to characterize their mechanical and chemical stability. ABSTRACT The Cathedral of São Sebastião in Rio de Janeiro (Brazil) contains a series of concrete stained‐glass windows made using the dalle de verre technique, which have undergone a natural degradation process.

A Novel Ice Cloud Optical Property Model for Passive and Active Remote Sensing Applications

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract A new broad‐spectrum ice cloud optical property model, namely the Passive‐Active Remote Sensing Consistent (PARSC) model, is developed to achieve consistency between passive and active sensor‐based ocean‐occurring ice cloud property retrievals.

Method and Device for Monitoring Residual Stress in Glass Products

Technologia i Automatyzacja Montażu
Stress in glass products arises from poor thermal conductivity and different cooling conditions of the outer and inner layers. Excessive stress levels and their uneven distribution adversely affect the mechanical and thermal strength, as well as the ...

Spatially Resolved Scattering Polarimeter [PDF]

, 2009
We demonstrate a compact, spatially resolved polarimeter based on a coherent optical fiber bundle coupled with a thin layer of scattering centers. The use of scattering for polarization encoding allows the polarimeter to work across broad angular and ...

Development of cosmic x-ray polarimeter [PDF]

, 2006
We present a performance study of a cosmic X-ray polarimeter which is based on the photoelectric effect in gas, and sensitive to a few to 30 keV range. In our polarimeter, the key device would be the 50 μm pitch Gas Electron Multiplier (GEM).
