Computation of Implicit Representation of Volumetric Shells with Predefined Thickness

Algorithms, 2021
We propose and validate a method to find an implicit representation of a surface placed at a distance h from another implicit surface. With two such surfaces on either side of the original surface, a volumetric shell of predefined thickness can be ...

Sustainable Dreams, Overlooked Realities: Closing the Design–Outcome Gap in Sustainable Business Models

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainable business models (SBMs) are enablers of the circular economy (CE) and sustainability. However, its adoption does not always improve environmental performance. This study investigates the conditions under which SBM design does (or does not) produce the expected environmental benefits.

Clinical trial barriers in neurostimulation for pediatric drug‐resistant epilepsy

Epileptic Disorders, EarlyView.
Abstract Objective The NeuroPace responsive neurostimulation (RNS) System effectively treats focal drug‐resistant epilepsy (DRE) in adults but lacks pediatric regulatory approval. Despite effective off‐label pediatric use, systemic device‐trial challenges have impeded label expansion.

Accelerated Exponentially Fitted Operator Method for Singularly Perturbed Problems with Integral Boundary Condition

International Journal of Differential Equations, 2020
In this paper, we consider a class of singularly perturbed differential equations of convection diffusion type with integral boundary condition. An accelerated uniformly convergent numerical method is constructed via exponentially fitted operator method ...

Monthly or menstrual? A scoping review of catamenial epilepsy and non‐menstrual seizure rhythms

Epilepsia, EarlyView.
Abstract Objective Despite the reported high prevalence of catamenial epilepsy (CE), the condition remains poorly defined, with lack of consensus on what entails a menstrual‐related seizure exacerbation. Emerging evidence of multiday cycles of seizure activity, including about‐monthly cycles, present in both men and women, further confound the ...

Treatment Outcomes in Osteosarcoma of the Head and Neck: A Systematic Review and Meta‐Analysis

Head &Neck, EarlyView.
ABSTRACT Background Head and neck osteosarcomas (HNOS) are rare, accounting for ~1% of head and neck malignancies. This study systematically evaluated the role of chemotherapy (CT) and radiotherapy (RT) on survival outcomes. Methods A systematic review and meta‐analysis were performed following PRISMA guidelines across six databases.

Asymptotic Expansions for Approximate Solutions of Hammerstein Integral Equations with Green's Function Type Kernels

Mathematical Modelling and Analysis, 2014
We consider approximation of a nonlinear Hammerstein equation with a kernel of the type of Green's function using the Nyström method based on the composite midpoint and the composite modified Simpson rules associated with a uniform partition.

Prognostic Impact of Lymphovascular Invasion on Distant Metastasis in HPV‐Negative Head and Neck Cancer

Head &Neck, EarlyView.
ABSTRACT Background Lymphovascular invasion (LVI) is a recognized poor prognostic factor in head and neck squamous cell carcinoma (HNSCC), particularly for regional recurrence and overall survival. However, its role in predicting distant metastasis, especially in HPV‐negative HNSCC, remains unclear. Objective To evaluate the association between LVI and

The convergence of explicit Runge-Kutta methods combined with Richardson extrapolation [PDF]

, 2012
summary:Runge-Kutta methods are widely used in the solution of systems of ordinary differential equations. Richardson extrapolation is an efficient tool to enhance the accuracy of time integration schemes.

Characteristics of Boundary Layer Height Variations in Global Arid Regions and Their Sensitivity to Influencing Energy Factors

International Journal of Climatology, EarlyView.
Global warming has intensified drought impacts across most arid regions, altering surface energy partitioning and atmospheric boundary layer (ABL) development. Using 1979–2018 ERA‐Interim reanalysis data, we show that the long‐term mean boundary layer height (BLH) over global arid regions is approximately 841.8 m, nearly 200 m higher than over humid ...
