Solution of a pseudoparabolic equation with nonlocal integral conditions by the finite difference method. [PDF]

, 2013
The thesis analyzes the third-order one-dimensional pseudoparabolic equations with two types of nonlocal conditions. The stability of difference schemes for this problem was studied using the analysis of the spectrum structure of a difference operator ...

A Semi‐Analytical Energy Model for Particle‐Based Fluid Simulation Involving Complex Moving Boundaries

Computer Graphics Forum, EarlyView.
Abstract While semi‐analytical boundary handling techniques have proven effective for modeling particle‐based fluid‐solid interactions, they can become unstable when applied to mesh boundaries undergoing dynamic motion or featuring complex, sharp geometries.

Volumetric Inverse Rendering via Neural Radiative Transfer

Computer Graphics Forum, EarlyView.
Abstract Volumetric inverse rendering seeks to recover the optical properties of participating media from images. Existing approaches either rely on differentiable stochastic light transport simulation, which require substantial algorithmic effort, or use simplified models that fail to capture global illumination.

KPI‐NeRF: Hyperspectral Neural Radiance Fields from a Single Kaleidoscopic Plenoptic Image

Computer Graphics Forum, EarlyView.
KPI‐NeRF reconstructs hyperspectral light field images from a single kaleidoscopic plenoptic image. By leveraging neural radiance fields, it enables high‐quality spectral and angular de‐multiplexing for dynamic scene capture. Abstract Plenoptic imaging has excessive sampling requirements associated with the high dimensionality of the desired data.

Improved European native seed supply chains are essential for the implementation of the Nature Restoration Regulation

Conservation Science and Practice, EarlyView.
To ensure the timely implementation of the European Nature Restoration Regulation, native seed supply has to be improved. In this perspective paper, we call for the adoption of the concept of Native Seed and Restoration Centres (NSRCs) to boost seed supply chains.

When Virchow's law fails: Crouzon syndrome as a test case for quantitative suture closure–endocranial shape relationships

Journal of Anatomy, EarlyView.
Crouzon syndrome shows preserved intracranial volume but profoundly altered endocranial shape, with disrupted allometric coupling relative to controls. Treating calvarial suture patency as a continuous, age‐adjusted variable reveals strong system‐level covariation with endocranial morphology, effects invisible to conventional categorical suture scoring.

Global existence and blow-up of solutions for parabolic systems with nonlinear nonlocal boundary conditions

Electronic Journal of Differential Equations, 2013
In this article we study a nonlinear parabolic system with nonlinear nonlocal boundary conditions. We prove the uniqueness of the solutions and establish the conditions for global solutions and non-global solutions.

Beyond the Wind: Mapping Externalities and Their Role in Shaping Willingness To Pay for Wind Energy

Journal of Economic Surveys, EarlyView.
ABSTRACTWind power plays a central role in global low‐carbon energy transitions, offering significant environmental benefits through reduced greenhouse gas emissions and decreased reliance on fossil fuels. Yet, local opposition to wind projects persists, often driven by perceived externalities affecting communities and landscapes. This study conducts a

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube

Journal of Economic Surveys, EarlyView.
ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

Firm Productivity and Exit During Economic Crisis: Does Market Potential Foster Resilience?

Journal of Regional Science, EarlyView.
ABSTRACT This paper examines the relationship between firm productivity, market potential, and firm exit over the economic cycle, focusing on the COVID‐19 crisis. Using Spanish firm‐level data (2011–2022), we analyse how market potential shapes the link between productivity and survival.
