Slope assisted Physics‐informed neural networks for seismic signal separation with applications on ground roll removal and interpolation

Geophysical Prospecting, EarlyView.
Abstract The knowledge of the local slope field of prestack seismic data is essential in several seismic signal processing tasks. Building on our previous slope‐assisted, physics‐informed seismic interpolation framework, dubbed PINNslope, we introduce a series of enhancements that elevate the framework's versatility.

Bacterial colony biopsies: Spatial discrimination of heterogeneous cell types by cytometric fingerprinting

Methods in Ecology and Evolution, EarlyView.
Abstract Colonies of pure bacterial strains are highly dense cellular structures organised in distinct and typical arrangements. The size, shape and variability of bacterial colonies are strongly species‐dependent and also influenced by environmental conditions. However, the spatial organization of individual cells is unknown for most strains.

Extremely asymmetric ectasia: Tomographically unilateral keratoconus

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the characteristics of apparently stable forms of tomographically unilateral keratoconus (KC). Methods In this retrospective case–control study, strict unilaterality criteria were applied to select tomographically unilateral cases with ≥3 years of follow‐up.
