Discharge‐Targeted Hydraulic Tomography to Quantify and Locate Aquifer Discharge

open access: yesGroundwater, EarlyView.
Abstract Quantifying and localizing groundwater discharge is inherently difficult. It requires knowledge about hydraulic conductivity and the hydraulic gradient on the scale of interest. Conventional hydraulic testing, such as pumping tests, may fail in the presence of heterogeneity and complex structural boundaries.

Stationary-excess operator and convex stochastic orders [PDF]

open access: yes
The present paper aims to point out how the stationary-excess operator and its iterates transform the s-convex stochastic orders and the associated moment spaces.

On Integral Priors for Multiple Comparison in Bayesian Model Selection

open access: yesInternational Statistical Review, EarlyView.
Summary Noninformative priors constructed for estimation purposes are usually not appropriate for model selection and testing. The methodology of integral priors was developed to get prior distributions for Bayesian model selection when comparing two models, modifying initial improper reference priors. We propose a generalisation of this methodology to

Never, Ever Getting Started: On Prospect Theory Without Commitment

open access: yesMathematical Finance, EarlyView.
ABSTRACT Prospect theory is arguably the most prominent alternative to expected utility theory. We study the investment or gambling behavior of a prospect theory decision maker who is aware of his time‐inconsistency but lacks commitment. For the empirically relevant prospect theory specifications, we obtain the extreme prediction that such a decision ...

Equilibrium Reward for Liquidity Providers in Automated Market Makers

open access: yesMathematical Finance, EarlyView.
ABSTRACT We find the equilibrium contract that an automated market maker (AMM) offers to their strategic liquidity providers (LPs) in order to maximize the order flow that gets processed by the venue. Our model is formulated as a leader–follower stochastic game, where the venue is the leader and a representative LP is the follower.

An accurate analytical approximation for the price of a European-style arithmetic Asian option. [PDF]

open access: yes
For discrete arithmetic Asian options the payoff depends on the price average of the underlying asset. Due to the dependence structure between the prices of the underlying asset, no simple exact pricing formula exists, not even in a Black-Scholes setting.

Jumps and stochastic volatility in crude oil prices and advances in average option pricing [PDF]

open access: yes, 2016
Crude oil derivatives form an important part of the global derivatives market. In this paper, we focus on Asian options which are favoured by risk managers being effective and cost-saving hedging instruments.

A Fuzzy‐Logic and Machine Learning‐Based Framework for Water Quality Index Classification in Extensive and Intensive Aquaculture Systems

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This study presents an Internet of Things (IoT)‐to‐Cloud framework for real‐time monitoring and prediction of the Water Quality Index (WQI) across both extensive and intensive aquaculture systems. By integrating Fuzzy Logic biological thresholds with ML classification, the Random Forest model achieves over 99.5% accuracy in both environments ...
