Titan's Plains Revealed: Evidence for a Layered Surface

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Undifferentiated plains are the most common terrain type on Titan, yet their composition and geologic history remain poorly understood. To better characterize their physical properties, we combined Cassini RADAR measurements from nadir altimetry and side‐looking SAR modes. We analyzed these data using radar backscatter models, finding that the

The Characteristics of Pekeris Modes Revealed by Long‐Term Reanalysis Data JAWARA Covering the Entire Middle Atmosphere

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract The characteristics of Pekeris modes as well as Lamb modes are investigated using the new reanalysis data set JAWARA, which spans over 19 years and covers the entire middle atmosphere. Pekeris modes are a class of global normal modes whose energy is trapped in two height regions that is, around the stratopause and the surface, while the energy

Noise hazard to the population of areas connected with functioning of roadway frontier crossings

open access: yesArchives of Acoustics, 2014
In spite of Polish observing the Schengen Convention connected with the freedom of internal moving in European Union, the problem of operating the external frontiers is still valid. Such border crossings can be crossed only at the special border crossing

Modelling the Effects of Urban Growth on Land Surface Temperature and Carbon Emissions Through Geospatial and Machine Learning Techniques in Gazipur, Bangladesh

open access: yesGeo: Geography and Environment, Volume 13, Issue 1, January/June 2026.
Short Abstract This study analyses the impact of rapid urban expansion on seasonal land surface temperature (LST) and carbon emissions in Gazipur, Bangladesh, from 2003 to 2023, with projections to 2043 using geospatial and machine learning models. Results indicate a significant increase in built‐up area and LST, as well as strong correlations between ...
