Study of Total Electron Content-TEC and electron density profile during geomagnetic storms

, 2018
Total Electron Content (TEC) and electron density are the basic parameters, which determine the major properties of the Ionosphere. Detail study of the ionospheric TEC and electron density variations has been carried out during geomagnetic storms, with longitude and latitude, for four different locations: (24 W-14 W, 25 S-10 S); (53 W- 46 W, 04 ...

Analisis Fluktuasi Total Electron Content (TEC) Akibat Gempa Palu dengan Formosat-3 / COSMIC

Jurnal Teknik: Media Pengembangan Ilmu dan Aplikasi Teknik, 2023
Gempa bumi merupakan getaran yang terjadi akibat dari adanya pergeseran lempeng. Gempa bumi yang terjadi akan menimbulkan 3 macam gelombang dan salah satunya adalah gelombang akustik yang bergerak secara vertikal dan mempengaruhi electron yang bergerak bebas di lapisan ionosfer.

Infrared Nanocrystals for Space Application: Hardness to Irradiations

Advanced Functional Materials, EarlyView.
This article investigates infrared HgTe nanocrystals under X‐ray and ion irradiation, revealing remarkable radiation hardness. It uncovers distinct degradation mechanisms and shows that the nanomaterial outperforms integrated electronics. The results position colloidal nanocrystals as promising candidates for resilient space and harsh‐environment ...

High-precision Measurements of Ionospheric TEC Gradients with the Very Large Array VHF System

, 2012
We have used a relatively long, contiguous VHF observation of a bright cosmic radio source (Cygnus A) with the Very Large Array (VLA) to demonstrate the capability of this instrument to study the ionosphere.

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

Advanced Functional Materials, EarlyView.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Application of Kalman filter in detecting pre-earthquake ionospheric TEC anomaly

Geodesy and Geodynamics, 2011
: As an attempt, the Kalman filter was used to study the anomalous variations of ionospheric Total Electron Content (TEC) before and after Wenchuan Ms8.0 earthquake, these TEC data were calculated from the GPS data observed by the Crustal Movement ...

DNA‐Origami‐Assembled Rhodium Nanoantennas for Deep‐UV Label‐Free Single‐Protein Detection

Advanced Functional Materials, EarlyView.
Deep‐UV autofluorescence of single proteins in DNA origami‐based rhodium nanoantennas. Precisely positioned within the plasmonic nanogap, proteins retain their native state while their intrinsic emission is strongly amplified, enabling label‐free single‐molecule detection and opening new opportunities for highly sensitive and specific biosensing ...
