Cartesian Grid Generator (2-D)
, 1999 A Cartesian Grid generator (2-D) has been developed in FORTRAN to create grids around arbitrary 2-D - shapes. The code has been based on a capturing technique in which the interruptions of a moving point along specified geometry with the cartesian mesh ...

View Order With Arbitrary Center Echoes
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Coexistence, crossover and extirpation in coalescent communities and ecotones
Oikos, EarlyView.When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Synthetic Aperture Imaging with ⊤-,
Remote SensingThe key performance of microwave imaging radiometers by aperture synthesis is governed by spatial resolution, radiometric sensitivity, and the extent of the synthesized field of view that is free from any aliasing artifact.

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.
