A Physics-Informed Neural Network Framework for Quasi-Steady Wind Retrieval From Doppler Lidar Observations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Accurate and rapid retrieval of quasi-steady wind fields is crucial to many operational applications, such as air traffic management. Classical three-dimensional variational methods (3DVAR) are widely used in such scenarios, but their grid-based ...

Field-Wise Wind Retrieal for the NASA Scatterometer [PDF]

, 1998
Traditional satellite scatterometer wind retrieval algorithms consist of point-wise wind estimation and point-wise ambiguity removal. Pointwise estimation yields multiple estimates, or ambiguities, for the near-surface ocean wind in each scatterometer ...

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Wind Profile Retrieval Based on LSTM Algorithm and Mobile Observation of Brightness Temperature over the Tibetan Plateau

Remote Sensing
Stationary or mobile microwave radiometers (MRs) can measure atmospheric temperature, relative humidity, and water vapor density profiles with high spatio-temporal resolution, but cannot obtain the vertical variations of wind field. Based on a dataset of

Drop‐on‐Demand Printed Negative Dielectric Anisotropy Liquid Crystal Droplets for Adaptive Complex Beam Manipulation and Assessment

Advanced Functional Materials, EarlyView.
Printed negative‐dielectric‐anisotropy liquid‐crystal droplets enable multidimensional full‐vectorial optical‐field sensing across polarization, phase, and wavelength, while also generating tunable skyrmionic‐like complex optical fields. ABSTRACT Adaptive manipulation of vectorial optical fields is important for optical metrology, imaging, and ...
