Toward a theory of Bayesian experimentation in early‐stage ventures

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary The entrepreneurship literature has established the benefits of experimentation but has paid comparatively little attention to its costs. We develop a Bayesian model to illustrate the entrepreneurial choice between direct and experimental entry.

Modelling Heterogeneous Dependence in a Copula‐Linked By‐Production Frontier: Evidence From French Dairy Farms

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT In agriculture, production technologies are often characterised by non‐linearities and stochastic dependence between outputs, particularly between desirable and undesirable outputs. This paper combines the copula‐based semi‐parametric framework for modelling heterogeneous dependence with the by‐production stochastic frontier approach and ...

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

open access: yesComputer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Establishing Shape Correspondences: A Survey

open access: yesComputer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Precautionary Saving against Correlation under Risk and Ambiguitya

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract This paper considers precautionary saving against the correlation between two risky attributes (wealth and health) and investigates how the correlation affects optimal savings under multivariate preferences. The signs of higher‐order cross‐derivatives play a key role in determining the direction of precautionary saving against such correlation.

The Evolution of Portfolio Theory Under Risk & Uncertainty: From Mean–Variance to AI‐Augmented Investing

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT This article summarizes the evolution of portfolio theory from mean–variance optimization to AI‐augmented investment systems. Rather than treating portfolio models as isolated techniques, it organizes the literature as a sequence of responses to different forms of uncertainty: variance, systematic risk, expected‐return estimation error ...

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Gradient Systems and Scale‐Aware Heat Equations

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The extreme miniaturization of modern microelectronic architectures exposes the limitations of classical continuum mechanics, as Fourier's law breaks down at sub‐micron scales (100–0.1 μm$\umu{\rm m}$). While molecular models can accurately capture these thermal flow regimes, they remain computationally expensive.

Combining phenomic and genomic selection for pea breeding improvement

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Pea (Pisum sativum L.) is a strategic crop in the development of sustainable agriculture. However, the genetic gain remains limited despite advances in breeding. Genomic selection holds promise to accelerate varietal improvement, but its high implementation cost restricts its use in crops.

Matchings: Source, goal, and faithful companion

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 4, October 2026.
Abstract Matchings were among the earliest motivations for graph theory. They subsequently remained a central goal, inspiring the development of new mathematical tools that went well beyond problems directly concerning matchings. These tools proved widely applicable, accompanying the growth of graph theory over the past century.
