Angewandte Chemie International Edition, EarlyView.By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

Filtering of Azimuth Ambiguity in Stripmap Synthetic Aperture Radar Images
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014 Due to the specific characteristics of the SAR system, peculiar artifacts can appear on SAR images. In particular, finite pulse repetition frequency (PRF) and nonideal antenna pattern give rise to azimuth ambiguity, with the possible presence of “ghosts” on the image.

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil
The Anatomical Record, EarlyView.Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Azimuth ambiguity suppression in SAR images using Doppler-sensitive signals [PDF]
, 2015 In the article the problem of the azimuth ambiguity in synthetic aperture radar (SAR) images and its genesis are presented. A method of suppressing the ambiguities by utilization of Doppler-sensitive signals is proposed, and the necessary modifications ...

Range Ambiguity Suppression Approach for Quad-pol SAR Systems Based on Modified Azimuth Phase Coding
Leida xuebao, 2017 For conventional quadrature-polarimetric (quad-pol) Synthetic Aperture Radar (SAR) systems, as cross-polarized (cross-pol) channels are influenced by the strong co-polarized (co-pol) range ambiguous returns, the range ambiguity levels of cross ...

Energy‐Flow Regimes and Their Temporal Transitions in a PV‐Building System
Energy Science &Engineering, EarlyView.Unlike production and consumption, which act as external factors, generated energy flows reflect the system's internal behavior regarding energy allocation at each time step. The combination of self‐consumption, surplus, and import of surplus energy into the power grid characterizes how electricity is routed between the building's local consumption and

Coherent Azimuth Ambiguity Removal from Along-Track Interferometric Synthetic Aperture Radar Data for the Harmony Mission [PDF]
, 2022 Coherent azimuth ambiguities in interferometric synthetic aperture radar (InSAR) can be a major systematic error source if accompanied by a low suppression capability.

Immersed Boundary Projection Method for Boundaries With Slip Velocities
International Journal for Numerical Methods in Fluids, EarlyView.A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

A spectroscopic method for the solution of the 180-deg azimuth ambiguity in magnetograms
The Astrophysical Journal, 1993 A spectroscopic method is proposed for removing the azimuth ambiguity intrinsically present in vector magnetograms. The method is based on the idea that the polarization observed in resonance lines (typically formed at the chromospheric level) depends not only on the magnetic field vector, but also on the anisotropy of the radiation field that is ...

Ship Discrimination Using Polarimetric SAR Data and Coherent Time-Frequency Analysis
Remote Sensing, 2013 This paper presents a new approach for the discrimination of ship responses using polarimetric SAR (PolSAR) data. The PolSAR multidimensional information is analyzed using a linear Time-Frequency (TF) decomposition approach, which permits to describe the
