Improved Ionospheric Correction for Dual Frequency and Differential GPS Positioning Methods [PDF]
, 2007 A new three dimensional (3-D) electron density model has been developed that can give a very accurate description of the real ionospheric variation; latitudinally,longitudinally and altitudinally.

Inorganic Nanomaterials can Promote or Inhibit Tumor Metastasis Depending on Tumor Microenvironment Composition. [PDF]
Adv Sci (Weinh)As engineered nanomaterials gain prominence in cancer imaging and therapy, understanding their impact on tumor progression becomes increasingly critical. We demonstrate that gold and silica‐coated gold nanomaterials can either suppress or enhance breast cancer metastasis through distinct tumor microenvironment interactions, while identifying ...

Analisis Fluktuasi Total Electron Content (TEC) Akibat Gempa Palu dengan Formosat-3 / COSMIC [PDF]
, 2023 Earthquakes are vibrations that occur as a result of plate shifts. When an earthquake occurs, it will cause three kinds of waves, and one of them is an acoustic wave that moves vertically and affects electrons that move freely in the ionosphere.

Geometric quality term for station-based total electron content estimation
Annals of Geophysics, 2016 Global ionospheric maps (GIMs) are still commonly used to represent total electron content (TEC). However, a large number of permanent GPS receivers provide significant data for monitoring ionosphere.
