LamelODF: a MATLAB‐based toolbox for orientation distribution analysis and mapping of lamellar minerals for laboratory and synchrotron X‐ray diffractometers

open access: yesJournal of Applied Crystallography, EarlyView.
LamelODF is a MATLAB‐based toolbox aimed at simplifying the automated extraction of orientation distribution functions from 2D X‐ray diffraction data of lamellar minerals in transmission mode. It accommodates both laboratory and synchrotron data formats, providing an integrated pipeline from raw data to spatially resolved textural maps, enabling robust

Detector alignment for X‐ray crystallography using Millepede‐II

open access: yesJournal of Applied Crystallography, EarlyView.
A computational method for refinement of multi‐panel detector geometry has been adapted from high‐energy physics to serial crystallography. The method is many times faster and much more accurate than previous approaches.I describe a method for accurately refining the geometrical parameters of segmented X‐ray area detectors on the basis of serial ...

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Applying the maximum entropy principle to neural networks enhances multi‐species distribution models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The increasing volume of presence‐only (PO) data generated by citizen science initiatives has greatly expanded biodiversity databases, but the statistical use of these data in species distribution models (SDMs) remains limited by strong sampling biases and the absence of reliable absence information.

Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Elections can lead to substantial policy changes and, thus, are a significant source of risk. Firms can respond to such policy uncertainty by lobbying, but it is hard to quantify whether they do so and, if so, how much lobbying benefits them. We construct a new dataset and leverage investors’ expectations of variability in stock returns in the

Style Brush: Guided Style Transfer for 3D Objects

open access: yesComputer Graphics Forum, EarlyView.
We introduce Style Brush, a guided 3D style‐transfer method for textured meshes that provides precise creative control. It supports the use of multiple style images, smooth transitions and intuitive guidance, producing visually appealing textures that follow user intent as we demonstrate in our user study and results. Abstract We introduce Style Brush,

Mesh Processing Non‐Meshes via Neural Displacement Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract Mesh processing pipelines are mature, but adapting them to newer non‐mesh surface representations—which enable fast rendering with compact file size—requires costly meshing or transmitting bulky meshes, negating their core benefits for streaming applications.

Minimax Parametric Optimization Problems and Multidimensional Parametric Searching

open access: yesMinimax Parametric Optimization Problems and Multidimensional Parametric Searching
application/pdf The parametric minimax problem, which finds the parameter value minimizing the weight of a solution of a combinatorial maximization problem, is a fundamental problem in sensitivity analysis. Moreover, several problems in computational geometry can be formulated as parametric minimax problems.

Register‐Efficient Linear‐Time Evaluation in the Bernstein Basis

open access: yesComputer Graphics Forum, EarlyView.
Abstract We investigate the evaluation of points and derivatives of Bézier curves and surfaces on modern architectures, focusing on performance and guided by numerical error bounds. While the de Casteljau algorithm remains the reference for numerical robustness, its linear working‐set size imposes substantial register pressure on GPUs.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

open access: yesConservation Biology, EarlyView.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models
