ChemPhysChem, Volume 27, Issue 20, 28 October 2026.The interaction of α$\alpha$‐synuclein with lipid membranes in the synapse is intensively discussed in view of pathologies of neurodegeneration. By X‐ray diffraction from monolayer, lipid vesicles, and synaptic vesicles at different α$\alpha$‐synuclein concentrations, structural changes of the membrane can be probed in response to the interaction.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract On 2 May 2025, an Mw 7.4 earthquake occurred ∼120 km off the southern tip of Tierra del Fuego, at the transition of the Shackleton Fracture Zone and the Chile Trench. This event exhibits reverse‐faulting mechanisms with relatively steeply dipping planes and is the largest recorded along this complex plate boundary.

BridgeSAR: Measuring Bridge‐Water Clearance From Space Using SAR Multipath Signatures
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Bridge‐water clearance controls safe vessel passage and reflects local water‐level changes, but direct measurements are unavailable at many bridges. We present BridgeSAR, a geometry‐guided method that estimates clearance from multipath scattering stripes in synthetic aperture radar (SAR) amplitude images.

Estimation of Range Ambiguities for Correlation Based Calibration
, 2023 There is an evolutionary trend for Synthetic Aperture Radar (SAR) missions to employ multiple channels in azimuth and elevation. Paired with Digital Beam-Forming (DBF) techniques, it allows to achieve a high resolution and a wide swath. In elevation, a

SAR Cross-Ambiguities in SAOCOM-CS Large Baseline Bistatic Configuration [PDF]
, 2016 The evaluation of the ambiguous signal level, the Ambiguity-to-Signal Ratio (ASR), plays a key role in the Synthetic Aperture Radar (SAR) design and performance prediction. In conventional SAR acquisition scenarios, the computation of the ASR is based on

Minimizing Peak Sidelobe Level in MIMO-SAR Waveform Design Using a 1.5-Entmax Sparse Loss
Remote SensingThe peak sidelobe level (PSL) of an orthogonal waveform set directly governs the range and azimuth ambiguities of synthetic aperture radar (SAR) images and is therefore a key figure of merit for the imaging quality of multiple-input multiple-output SAR ...
