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.

Frequency spectra of nonlocal Timoshenko beams and an effective method of determining nonlocal effect

, 2017
Three critical frequencies independent of boundary conditions together with a critical length, which determine the vibration behaviors of a nonlocal Timoshenko beam, are identified.

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.

Continuum limits of nonlocal $p$-Laplacian variational problems on graphs

, 2019
Accepté dans SIAM Journal on Imaging SciencesInternational audienceIn this paper, we study a nonlocal variational problem which consists of minimizing in $L^2$ the sum of a quadratic data fidelity and a regularization term corresponding to the $L^p$-norm

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.

Structure and asymptotic expansion of eigenvalues of an integral-type nonlocal problem

Electronic Journal of Differential Equations, 2016
We study the structure of eigenvalues of second-order differential equations with nonlocal integral boundary conditions. Moreover, we consider the asymptotic expansion of the eigenvalues and the corresponding eigenfunctions, which shows that the ...

Independent Effects of Age, Education, Verbal Working Memory, Motor Speed of Processing, Locality, and Morphosyntactic Category on Verb‐Related Morphosyntactic Production: Evidence From Healthy Aging

Topics in Cognitive Science, EarlyView.
Abstract This study investigates the role of locality (a task/material‐related variable), demographic factors (age, education, and sex), cognitive capacities (verbal working memory [WM], verbal short‐term memory [STM], speed of processing [SOP], and inhibition), and morphosyntactic category (time reference and grammatical aspect) in verb‐related ...
