Defected Ground Structure (DGS) Based MIMO Antenna Array With Decent Isolation Characteristics for Satellite Communications in Unified S‐Band (USB)

Radio Science, Volume 60, Issue 11, November 2025.
Abstract This research focuses on developing an efficient, high‐isolation Multi‐Input Multi‐Output (MIMO) antenna array for Mobile Satellite Services (MSS). A portion of the S‐band (2–4 GHz) ranging from 2 to 2.2 GHz, known as Unified S‐Band (USB), is utilized for MSS, particularly for Space‐to‐Earth communications.

AstroGeoFit. A Genetic Algorithm and Bayesian Approach for the Astronomical Calibration of the Geological Timescale

Paleoceanography and Paleoclimatology, Volume 40, Issue 8, August 2025.
Abstract Variations in Earth's orbit and axial tilt induce climatic changes which are recorded in sedimentary deposits. The frequencies of these cyclical variations are integer combinations of the main secular frequencies of the solar system. Analyzing these cycles in sedimentary records can help establish an astronomical time scale for the geological ...

Nanoscale Curvature Regulates YAP/TAZ Nuclear Localization Through Nuclear Deformation and Rupture

Advanced Science, Volume 12, Issue 28, July 24, 2025.
This study uses experiments and biophysical modeling to examine the response and adaptation of cells to nanoscale topography of surfaces. It is shown that cytoskeletal assembly and nuclear localization of transcription regulatory factors such as yes‐associated protein (YAP) and transcriptional coactivator with PDZ‐binding motif (TAZ) can be tuned by ...
