Real-Time Variants of Vertical Synchrosqueezing: Application to Radar Remote Sensing

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
This article presentsthorough research on using high-order vertical synchrosqueezing (VSS) in different radar remote sensing applications. The method well established in the literature is examined and compared to the novel form of third-order VSS and ...

Radar Remote Sensing of Agricultural Canopies: A Review

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Observations from spaceborne radar contain considerable information about vegetation dynamics. The ability to extract this information could lead to improved soil moisture retrievals and the increased capacity to monitor vegetation phenology and water stress using radar data.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

open access: yesAdvanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Determination of the turbulent fluxes of heat and momentum in the ABL by ground-based remote-sensing techniques (a Review)

open access: yesMeteorologische Zeitschrift, 2007
During the past about 20 years, quite a number of methods for estimation of vertical profiles of the turbulent fluxes of heat and momentum, estimated or measured by means of ground-based remote-sensing techniques have emerged.

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

open access: yesAdvanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Satellite Remote Sensing of the Greenland Ice Sheet Ablation Zone: A Review

open access: yesRemote Sensing, 2019
The Greenland Ice Sheet is now the largest land ice contributor to global sea level rise, largely driven by increased surface meltwater runoff from the ablation zone, i.e., areas of the ice sheet where annual mass losses exceed gains.

The potential of active and passive remote sensing to detect frequent harvesting of alfalfa

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Alfalfa (Medicago sativa L.), referred to as the “Queen of Forages” because of its importance among forage crops, provides high quality forage for the livestock industry. The timing and frequency of alfalfa hay harvesting have implications on its quality

In Situ Polyurea Integration for Self‐Healing, Durable Transparent Electromagnetic‐Interference Shielding Film

open access: yesAdvanced Science, EarlyView.
A steric‐hindrance molecular engineering strategy uses dimethyl maleate (DMM) to convert poly(1,4‐butanediol) bis(4‐aminobenzoate) (PBDAB) into a precursor with reduced reactivity via Michael addition, thereby retarding the curing process to form a transparent, ultraflexible, and self‐healable secondary‑amine polyurea (PuSA) with a crosslinked network.

Radar remote sensing of planetary surfaces [PDF]

open access: yesChoice Reviews Online, 2002
Radar has been recognized as a practical tool for Earth and planetary science for more than 30 years. In recent years, radar images from orbiting platforms have provided spectacular views of features as diverse as volcanoes in Guatemala, buried river channels in the Egyptian desert, and the surface of Venus.
