An Efficient Full-Aperture Approach for Airborne Spotlight SAR Data Processing Based on Time-Domain Dealiasing

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The two-step approach (TSA) is an efficient full-aperture method to solve the Doppler spectrum aliasing when processing data acquired by a synthetic aperture radar (SAR) system operating in beam steering mode.

Connecting tradition and technology: The digitization of the ethnobotanical collection at the Rio de Janeiro Botanical Garden

PLANTS, PEOPLE, PLANET, EarlyView.
The digitization of RBetno (JBRJ) represents a step forward for biodiversity conservation in Brazil. Aligned with the Kunming‐Montreal Global Biodiversity Framework (Target 2, 2020–2030), this project documents the use of plants, including traditional knowledge and vernacular names, with a focus on the Atlantic Forest and Amazon.

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

Small, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, EarlyView.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

An Optical Sensor for Measuring the Position and Slanting Direction of Flat Surfaces

Sensors, 2016
Automated optical inspection is a very important technique. For this reason, this study proposes an optical non-contact slanting surface measuring system. The essential features of the measurement system are obtained through simulations using the optical

Therapeutic Strategies to Overcome Payload Resistance of Trastuzumab Deruxtecan in HER2‐Positive Cancers

Cancer Science, EarlyView.
Overexpression of ABC transporters, especially ABCG2 and ABCB1, mediates acquired resistance to T‐DXd in HER2‐positive cancers. Inhibition of these transporters restored T‐DXd efficacy, highlighting efflux‐mediated resistance as a potential therapeutic target. ABSTRACT Antibody–drug conjugates (ADCs) are emerging as a promising class of targeted cancer

The technical and practical implementation of fundus photography in equids

Equine Veterinary Education, EarlyView.
Summary Background Fundus photography is an important diagnostic tool in human and veterinary medicine. Advances in research are increasing its accessibility in human medicine. However, there is a lack of studies on modern fundus photography in animals, particularly in horses. Objectives To assess the use of a portable fundus camera developed for human

A Robust Track Estimation Method for Airborne SAR Based on Weak Navigation Information and Additional Envelope Errors

Remote Sensing
As miniaturization technology has progressed, Synthetic Aperture Radar (SAR) can now be mounted on Unmanned Aerial Vehicles (UAVs) to carry out observational tasks. Influenced by airflow, UAVs inevitably experience deviations or vibrations during flight.

Factorized Geometrical Autofocus for Synthetic Aperture Radar Processing [PDF]

, 2013
Synthetic Aperture Radar (SAR) imagery is a very useful resource for the civilian remote sensing community and for the military. This however presumes that images are focused. There are several possible sources for defocusing effects.
