Medial Axis Aware Learning of Signed Distance Functions

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 th...

Extracranial reconstruction strategies for management of acute tandem occlusion strokes: hemorrhage risks and functional outcome

<title>Abstract</title> Background: Optimal extracranial management in acute ischemic stroke due to tandem occlusions remains controversial. Balloon-expandable stents used as a bridging strategy with reduced early antiplatelet therapy have been proposed to decrease hemorrhagic ri...

Photo‐Activated Merging Cascades in Droplet Swarms Upon Synergistic Solvation of Surfactants

ABSTRACT Chemically active droplets at fluid interfaces provide versatile building blocks for dynamic matter, yet most systems are limited to behavior encoded within individual droplets or simple pairwise interactions. Here, we report a strategy to generate non‐linear, cascading...

Thermodynamic characteristics of a twisted oval tube with dimples at varying positions

To further enhance the thermal performance of twisted oval tubes, this paper innovatively installs dimples at different positions on the cross-section of twisted oval tubes and investigates how the dimple position affects the flow and heat transfer characteristics in these tubes....

Progressive Convex Hull Simplification

Abstract Convex hulls are useful as tight bounding proxies for a variety of tasks including collision detection, ray intersection, and distance computation. Unfortunately, the complexity of polyhedral convex hulls grows linearly with their input. We consider the problem of conser...

On the simplicial structure of uncertain information

Abstract The mathematical representation of uncertainty has led to a proliferation of preference structures, such as interval-valued fuzzy sets, intuitionistic fuzzy sets, and various granular models. While these extensions are often studied independently, they share profound geo...

The Effects of Non-Premixed Hydrogen on Soot Formation in an Ethylene-Fuelled Laboratory-Scale Rich-Quench-Lean Combustor

Abstract This work investigates the effects of hydrogen blending on soot formation and flame structure in a laboratory-scale Rich-Quench-Lean (RQL) burner using ethylene-hydrogen mixtures (0-50 vol.% hydrogen) at constant carbon mass flow rate. Laser-induced incandescence and sin...

Evidence-based recommendations for application of construct-based splicing data in clinical variant classification

<title>Abstract</title> Background: Minigene RT-PCR assays are widely used to assess variant impact on splicing, with increasing reports of massively parallel splicing assays (MPSAs) demonstrating potential to upscale diagnostic use of construct-based data. This study conducted a...

Polarization calibration of spaceborne lidar using dense cirrus–scattered solar background with molecular scattering correction

Abstract. Accurate calibration is essential for spaceborne polarization-sensitive lidars, as biases in depolarization ratio measurements can significantly affect the retrieval of cloud and aerosol properties. A polarization calibration technique based on solar background signals...

Study of doubly heavy baryon lifetimes

A bstract We study the lifetimes and inclusive semileptonic decay widths of doubly heavy baryons within the framework of heavy quark expansion. Our analysis includes next-to-leading-order corrections to the dimension-3, -5, and -6 operators, together with the leading dimension-7...

Predicting The Extinction Condition For Gas Turbine Combustors

Abstract Capturing flame blow-off (BO) or extinction limits early in the combustor design process is essential for ensuring reliable performance and reducing development time and cost. This study investigates the applicability of a low-order extinction prediction model based on a...

Everyday emotion regulation and empathic accuracy in the parent–adolescent relationship.

Empathic accuracy, the ability to accurately infer another’s emotions, is critical for relational well-being. Adolescence is marked by heightened emotional intensity and increased conflict within the parent–adolescent relationship. It is therefore important to identify factors th...

Reductive Deoxygenationof Aromatic Aldehydes andKetones with Boron Triiodide

Abstract Deoxygenation of carbonyls is an area of value in synthetic transformations because it allows for the traceless utilization of carbonyl chemistry, a mainstay in synthetic manipulations. Since oxygenation patterns are common in biological settings, deoxygenation can also...

Hostility in high definition: Gendered aggression against female politicians on X in Spain

This study examines gendered aggression against female politicians in Spain on X through a Feminist Critical Discourse Analysis (FCDA), operationalised through Fairclough’s three-dimensional model. Drawing on 800 replies directed at Isabel Díaz Ayuso and Irene Montero, two ideolo...

Experimental study on the reinforcement performance of unloading-damaged mudstone by microbial grouting

<title>Abstract</title> To address the structural deterioration and water-induced swelling of mudstone caused by unloading damage during foundation excavation, grouting reinforcement tests using MICP and volcanic ash-assisted MICP were conducted. Mudstone specimens with unloading...

A Self‐Evolving Agentic Framework for Metasurface Inverse Design

ABSTRACT Metasurface inverse design can realize complex optical functionality, but turning a target optical response into executable optimization code still requires substantial expertise in computational electromagnetics and solver‐specific software engineering. We present a sel...

A variationally consistent beam-to-beam point coupling formulation for geometrically exact beam theories

Abstract Slender beam-like structures frequently occur in engineering applications and often interact at discrete locations through joints or connectors. Accurate modeling of such interactions is particularly challenging when different numerical formulations are involved in terms...

Clinical DVH metrics as a loss function for 3D dose prediction in head and neck radiotherapy

Abstract Purpose Deep learning-based three-dimensional (3D) dose prediction is widely used in automated radiotherapy workflows. However, most existing models are trained with voxel-wise regression losses, which are poorly aligned with clinical plan evaluation criteria based on do...

Buffon discrepancy and the Steinhaus longimeter

Abstract Let be a convex set. We study the problem of distributing a one‐dimensional set with total length so that for any line in the number of intersections is proportional to the length as much as possible; we use the term Buffon discrepancy for the largest error. A constructi...

Local minimality of the truncated octahedron for the isoperimetric problem on parallelohedra

Abstract We investigate the isoperimetric problem for the Voronoi cells of three-dimensional lattices. Using Selling parameters, we derive an explicit closed formula for the scale-invariant isoperimetric quotient F in terms of six non-negative variables. We then analyse the local...
