The effect of dimensionality reduction on signature-based target detection for hyperspectral imaging [PDF]
, 2019 Target detection is one of the more popular applications of hyperspectral remote sensing. To enhance the detection rate, it is common to do preprocessing to reduce the effects of noise and other forms of undesired interference with the observed spectral ...

Variability and trend in ozone over the southern tropics and subtropics [PDF]
Annales Geophysicae, 2018 Long-term variability in ozone trends was assessed over eight Southern Hemisphere tropical and subtropical sites (Natal, Nairobi, Ascension Island, Java, Samoa, Fiji, Reunion and Irene), using total column ozone data (TCO) and vertical ozone profiles (

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor
Advanced Functional Materials, EarlyView.Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

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.

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

A satellite view of the space-time variability of phytoplankton biomass in the Mediterranean Sea [PDF]
, 2010 The general thesis objective is to determine, with sufficient accuracy (i.e. using the most reliable datasets and techniques) the phytoplankton space time variability in the Mediterranean Sea (MED) using satellite data (SeaWiFS), at different timescales,

Advanced Functional Materials, EarlyView.A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.

Cancellation of cloud shadow effects in the absorbing aerosol index retrieval algorithm of TROPOMI [PDF]
Atmospheric Measurement TechniquesCloud shadows can be detected in the radiance measurements of the TROPOspheric Monitoring Instrument (TROPOMI) on board the Sentinel-5P satellite due to its high spatial resolution and could possibly affect its air quality products.
