Anchor Flow Maps: Efficient Sampling and Approximation of the Entire Flow Map
Computer Graphics Forum, EarlyView.Abstract Flow maps are a fundamental concept for the visualization and analysis of time‐dependent flows. A common approach is to apply sampling and reconstruction – which comes with a number of problems: flow maps are high‐dimensional functions with locally large gradients which makes approximations very challenging.

Medial Axis Aware Learning of Signed Distance Functions
Computer Graphics Forum, EarlyView.Abstract We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of the surface, is explicitly taken into account through a higher‐order variational formulation that enforces linear growth ...

Strictly Conservative Neural Distance Fields
Computer Graphics Forum, EarlyView.Abstract We propose a first method to generate neural unsigned or signed distance fields (SDFs) that are guaranteed to be conservative with respect to a given 3D shape. This means the true distance is never overestimated and the zero‐level set is a bounding volume for the shape. The method makes use of neural network architectures that ensure Lipschitz

A Splitting Architecture for Exact Reduced Coulomb Friction
Computer Graphics Forum, EarlyView.Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

SharpEdge: Edge Feature Surface Reconstruction From Space Curves
Computer Graphics Forum, EarlyView.SharpEdge reconstructs surfaces with sharp features from sparse 3D curve networks. By estimating dual normals along curves, our method preserves ridges and corners while producing high‐quality meshes. Abstract Reconstructing high‐quality surfaces from sparse 3D space curves remains challenging, particularly when sharp feature edges are involved ...

Phylogenetic and ecological duality in the otoliths of Sciaenidae
Cladistics, EarlyView.Abstract Teleost fishes have evolved taxon‐specific otoliths that vary greatly in size and shape and are primarily involved in hearing and balance. This study identifies the main drivers of otolith shape disparity in Sciaenidae, a clade of sound‐producing bony fishes, using three‐dimensional geometric morphometrics (3DGM).

Sleep profiles in individuals with rare neurogenetic syndromes
Developmental Medicine &Child Neurology, EarlyView.Aim To characterize sleep profiles in individuals with neurogenetic disorders (NGDs) and examine the contribution of key clinical and psychiatric symptoms to these profiles. Method The parents of 248 individuals (aged 3–45 years) diagnosed with a range of NGDs, including PTEN hamartoma tumor syndrome (n = 111), SYNGAP1‐related intellectual disability ...

Diabetes, Obesity and Metabolism, EarlyView.ABSTRACT Aims To evaluate the relative importance of attributes driving obesity medication (OM) choice and preferences among individuals with overweight or obesity. Materials and Methods US adults with obesity or overweight and ≥ 1 obesity‐related complication completed an online survey including a discrete‐choice experiment (DCE) in October–November ...

Diabetes, Obesity and Metabolism, EarlyView.ABSTRACT Aim To assess the health and economic consequences of a culturally adapted family‐model diabetes self‐management education (adapted DSME) program for Marshallese adults with type 2 diabetes (T2D) compared with standard DSME and usual care. Methods A state‐transition Markov model was constructed to predict costs and quality‐adjusted life years (

Using Catch Data to Estimate Changes in Global Commercial Abalone Abundance
Fisheries Management and Ecology, EarlyView.ABSTRACT Changes in global wild capture production of abalone are explored to infer potential changes in biological stocks. The study found that 77% (or 10 out of the 13) of the countries that reportedly caught abalone in the wild have experienced declines in catches between 1980 and 2023, and on aggregate catch declined by almost 83% between 1980 and ...
