, 2011 Standard image registration methods do not account for changes in image appearance. Hence, metamorphosis approaches have been developed which jointly estimate a space deformation and a change in image appearance to construct a spatio-temporal trajectory smoothly transforming a source to a target image.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Still slow, but even steadier: an update on the evolution of turtle cranial disparity interpolating shapes along branches [PDF]
Royal Society Open Science, 2017 In a previous study, we estimated the cranial disparity of turtles (Testudinata) through time using geometric morphometric data from both terminal taxa and hypothetical ancestors to compensate for temporal gaps in the fossil record.

Type Synthesis Method for Parallel Robots With Special Topologies
IEEE Access, 2023 This contribution presents a type synthesis method for parallel robots with special topologies. First, we defined the constraint-incidence matrix (CIM) to describe serial chains by utilizing the geometric properties of screw theory, revealing the motion ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Abelterium: Geometric Mosaics from the Villae of Casa da Medusa and Quinta do Pião
Journal of Mosaic Research, 2017 The study of geometric mosaics from Casa da Medusa and Quinta do Pião has made a significant contribution towards understanding both the decorative project of these villae in Abelterium (Alter do Chão) and the Roman presence in this region.

Entanglement entropy of the quantum Hall edge and its geometric contribution
Frontiers in Physics, 2022 Generally speaking, entanglement entropy (EE) between two subregions of a gapped quantum many-body state is proportional to the area/length of their interface due to the short-range quantum correlation.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
