Extremal Contours: Gradient-driven contours for compact visual attribution
Reza Karimzadeh, Albert Alonso, Frans Zdyb +2
Faithful yet compact explanations for vision models remain a challenge, as commonly used dense perturbation masks are often fragmented and overfitted, needing careful post-processi…
Spline refinement with differentiable rendering
Frans Zdyb, Albert Alonso, Julius B. Kirkegaard
Detecting slender, overlapping structures remains a challenge in computational microscopy. While recent coordinate-based approaches improve detection, they often produce less accur…
Adaptive Node Positioning in Biological Transport Networks
Albert Alonso, Lars Erik J. Skjegstad, Julius B. Kirkegaard
Biological transport networks are highly optimized structures that ensure power-efficient distribution of fluids across various domains, including animal vasculature and plant vena…
Modeling Full-Scale Leaf Venation Networks
Lars Erik J. Skjegstad, Julius B. Kirkegaard
The vascular network of leaves, comprising xylem and phloem, is a highly optimized system for the delivery of water, nutrients, and sugars. The design rules for these naturally occ…
Persistent pseudopod splitting is an effective chemotaxis strategy in shallow gradients
Albert Alonso, Julius B. Kirkegaard, Robert G. Endres
Single-cell organisms and various cell types use a range of motility modes when following a chemical gradient, but it is unclear which mode is best suited for different gradients.…
Local Clustering and Global Spreading of Receptors for Optimal Spatial Gradient Sensing
Albert Alonso, Robert G. Endres, Julius B. Kirkegaard
Spatial information from cell-surface receptors is crucial for processes that require signal processing and sensing of the environment. Here, we investigate the optimal placement o…
