Relative Convex Hull Determination from Convex Hulls in the Plane

, 2016
A new algorithm for the determination of the relative convex hull in the plane of a simple polygon A with respect to another simple polygon B which contains A, is proposed.

On the hull operator

Indagationes Mathematicae (Proceedings), 1976
AbstractHull operators, such as the closure, the linear, the convex, the positive hull operator, can be studied starting from a few fundamental properties. This paper deals with an operator jh deduced from a hull operator h, which e.g. characterizes the isolated points in case h is the topological closure operator and the extreme points in case h is ...

High Performance Room Temperature Multiferroic Properties of w‐MnSe Altermagnet

Advanced Functional Materials, EarlyView.
Using first‐principles calculations, for the first time the Altermagneto‐Ferroelectric Coupling Effect (AFCE) is proposed, which enables control of both electric polarization and spin splitting in the band structure due to polyhedral rotations. This uncovers robust multiferroicity in wurtzite MnSe at room temperature, offering an exciting route for ...

Validation of the HULL Score clinical prediction rule for unsuspected pulmonary embolism in ambulatory cancer patients

ERJ Open Research, 2023
Background Clinical prediction rules (CPRs) developed to predict adverse outcomes of suspected pulmonary embolism (PE) and facilitate outpatient management have limitations in discriminating outcomes for ambulatory cancer patients with unsuspected PE ...

The effect of lift on the wave-making resistance of multi-hull craft [PDF]

, 2007
A potential based panel method is presented to estimate the wave-making characteristics of multi-hull craft. In order to simulate the lifting potential flow around the sub-hulls, the method adopts mixed source/doublet distributions on the sub-hulls and ...

The Stein hull

Journal of Nonparametric Statistics, 2010
We are interested in the statistical linear inverse problem $Y=Af+\epsilon\xi$, where $A$ denotes a compact operator and $\epsilon\xi$ a stochastic noise. In a first time, we investigate the link between some threshold estimators and the risk hull point of view introduced in (5).

Tangential Loewner hulls

Annales Fennici Mathematici, 2021
Through the Loewner equation, real-valued driving functions generate sets called Loewner hulls. We analyze driving functions that approach 0 at least as fast as $a (T-t)^r$ as $t \to T$, where $r \in (0, 1/2)$, and show that the corresponding Loewner hulls have tangential behavior at time $T$.

Decoding Hydrogel Porosity: Advancing the Structural Analysis of Hydrogels for Biomedical Applications

Advanced Healthcare Materials, EarlyView.
Porosity governs transport mechanics in hydrogels, yet characterization in its native state remains challenging. This work harnesses particle tracking to uncover three‐dimensional pore geometric features in polyethylene glycol hydrogels. Measurements in the native state reveal pores characteristics are comparable to those obtained by cryogenic scanning

Improving the Detection, Assessment, Management and Prevention of Delirium in Hospices (the DAMPen-D study): protocol for a co-design and feasibility study of a flexible and scalable implementation strategy to deliver guideline-adherent delirium care

BMJ Open, 2022
Introduction Delirium is a complex condition in which altered mental state and cognition causes severe distress and poor clinical outcomes for patients and families, anxiety and stress for the health professionals and support staff providing care, and ...
