A flexible pressure sensor with triple‐gradient design of conductivity, modulus, and dimension in binary micro‐dome pixels is proposed. Based on precisely‐designed CNT/PDMS matrix, the device exhibits a linear sensitivity of 974.1 kPa−1 across range up to 1.8 MPa (R2 > 0.99), offering an effective strategy for potential applications in healthcare ...

Bistatic TerraSAR-X/F-SAR Spaceborne-Airborne SAR Experiment: Description, Data Processing and Results [PDF]
We report about the first X-band spaceborne-airborne bistatic SAR experiment, using the German satellite TerraSAR-X as transmitter and DLR's new airborne radar system F-SAR as receiver. The data were acquired early November 2007.

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

A Survey of Density Estimation for SAR Images [PDF]
Modeling of synthetic aperture radar (SAR) images has been an important topic of research since the inception of SAR satellites. Many theoretical and empirical models have been presented in literature to accurately model the amplitude SAR images. The

Here, we report a novel NIR fluorescent PROTAC platform that enables real‐time imaging and targeted degradation of Alzheimer's p‐Tau. Our lead compound effectively clears p‐Tau, reduces APP/Aβ, and alleviates cognitive deficits in AD mice. This work demonstrates a theranostic strategy for visualizing degradation and developing next‐generation AD ...

A Full-Aperture Frequency Scaling Algorithm for Processing Dechirped Sliding Spotlight SAR Data
This paper proposes a full-aperture method for processing sliding spotlight synthetic aperture radar (SAR) data with dechirp-on-receive. The frequency scaling algorithm (FSA) efficiently processes the dechirped signals because the range cell migration ...

F-SAR – DLR’s New Multifrequency Polarimetric Airborne SAR [PDF]
F-SAR identifies the successor of the well-known E-SAR system. The system is under development at the Microwaves and Radar Institute. The development was triggered by the demand for data being simultaneously acquired at different wavelengths and ...

Efficient Time-Domain Image Formation with Precise Topography Accommodation for General Bistatic SAR Configurations [PDF]
Due to the lack of an appropriate symmetry in the acquisition geometry, generalised bistatic SAR cannot benefit from the two main properties of low-to-moderate resolution monostatic SAR: azimuth-invariance and topography-insensitivity.

Electrode morphology is shown to govern oxygen‐bubble dynamics and interfacial mass transfer during water electrolysis. Positive‐curvature nanoneedles promote rapid release of small bubbles, sustain electrolyte renewal, and minimize mass‐transport losses, whereas flat and concave architectures increasingly retain bubbles.
