Differential SAR Interferometry with TerraSAR-X TOPS Data: Mexico City Subsidence Results [PDF]

open access: yes, 2012
In this paper we investigate the possibility to exploit TOPS data to measure ground displacement movements by means of Differential SAR Interferometry (DInSAR). Several critical points (i.e.

Comparison of Molecular Iodine Spectral Properties at 514.7 and 532 nm Wavelengths

open access: yesMeasurement Science Review, 2014
We present results of investigation and comparison of spectral properties of molecular iodine transitions in the spectral region of 514.7 nm that are suitable for laser frequency stabilization and metrology of length.

Lab‐Scale Fabrication Process Selection for Soft Robotics: Benchmarking, Tradeoffs, and Guidelines for Formative Manufacturing of Soft Silicone Components

open access: yesAdvanced Intelligent Systems, EarlyView.
Fabrication shapes soft robot performance, but benchmarking data and selection guidelines remain scarce. We fabricate silicone actuators using two molding techniques and three mold types, characterizing them with cycle testing, microscopy, profilometry, and 3D imaging. Applying our lab‐scale, soft robotics‐specific fabrication evaluation criteria shows

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Estimation of the Surface Velocity Field of Temperate Glaciers Using Airborne SAR Interferometry [PDF]

open access: yes, 2008
This paper presents a methodology to process airborne interferometric SAR data to measure surface velocity fields of temperate glaciers. First, a solution based on multi-squint is proposed to estimate residual motion errors (inaccuracies of the ...

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...

Stellar intensity interferometry: Astrophysical targets for sub-milliarcsecond imaging.

open access: yes, 2010
Intensity interferometry permits very long optical baselines and the observation of sub-milliarcsecond structures. Using planned kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial ...

Detection of Legionella Bacteria Using a Silicon‐Based Photonic Microring Resonator Biosensor Enhanced by Dielectrophoresis

open access: yesELECTROPHORESIS, EarlyView.
Silicon photonic biosensors enable label‐free, highly sensitive detection but struggle with living bacteria due to inefficient cell binding on nanoscale surfaces. We integrate a microring resonator with a dielectrophoretic electrode, actively concentrating Legionella cells near the sensor using alternating electric fields.
