Spectroscopic observations of the comet 29P/Schwassmann-Wachmann 1 at the SOAR telescope [PDF]

open access: green, 2018
We carried out photometric and spectroscopic observations of comet 29P/ Schwassmann-Wachmann 1 at the SOAR 4.1-meter telescope (Chile) on August 12, 2016. This paper presents the results of only spectroscopic analysis. The spectra revealed presence of CO$

LiCSBAS: An Open-Source InSAR Time Series Analysis Package Integrated with the LiCSAR Automated Sentinel-1 InSAR Processor

open access: yesRemote Sensing, 2020
For the past five years, the 2-satellite Sentinel-1 constellation has provided abundant and useful Synthetic Aperture Radar (SAR) data, which have the potential to reveal global ground surface deformation at high spatial and temporal resolutions. However,

Comet dust as a mixture of aggregates and solid particles: model consistent with ground-based and space-mission results [PDF]

open access: yes, 2009
The most successful model of comet dust presents comet particles as aggregates of submicron grains. It qualitatively explains the spectral and angular change in the comet brightness and polarization and is consistent with the thermal infrared data and ...

Weak Keys in the Rekeying Paradigm: Application to COMET and mixFeed

open access: yesIACR Transactions on Symmetric Cryptology, 2020
In this paper, we study a group of AEAD schemes that use rekeying as a technique to increase efficiency by reducing the state size of the algorithm. We provide a unified model to study the behavior of the keys used in these schemes, called Rekey-and ...

InSAR‐Derived Horizontal Velocities in a Global Reference Frame

open access: yesGeophysical Research Letters, 2023
Interferometric Synthetic Aperture Radar is used to measure deformation rates over continents to constrain tectonic processes. The resulting velocity measurements are only relative, however, due to unknown integer ambiguities introduced during ...

Evaluation of Genotoxic and Cytotoxic Effects of Gluten in Male Albino Mice

open access: yesBioscience Journal, 2023
Gluten is a protein commonly found in daily diets in the form of wheat, barley, rye, and other grains. It serves as the structural component in flour, providing the binding qualities that maintain the shape and texture of food items.

Lateral Variations in Lower Crustal Strength Control the Temporal Evolution of Mountain Ranges: Examples From South‐East Tibet

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Controversy surrounds the rheology of the continental lithosphere, and how this rheology controls the evolution and behavior of mountain ranges. In this study, we investigate the effect of lateral contrasts in the strength of the lower crust, such as ...

The Formation of a Rubble Pile Asteroid: Insights from the Asteroid Ryugu

open access: yesUniverse, 2023
The Hayabusa2 mission returned primitive samples from the C-type asteroid Ryugu to Earth. The C-type asteroids hold clues to the origin of Earth’s water and the building blocks of life.
