Annalen der Physik, Volume 535, Issue 12, December 2023., 2023 The authors review the connections existing, based on potential theory, between contact mechanics and equilibrium electrostatics. This little known correspondence is exploited so that problems scattered in many works can be easily solved by bringing to light their “duals” in elastic theory.

A standard protocol to report discrete stage‐structured demographic information
Methods in Ecology and Evolution, Volume 14, Issue 8, Page 2065-2083, August 2023., 2023 Abstract Stage‐based demographic methods, such as matrix population models (MPMs), are powerful tools used to address a broad range of fundamental questions in ecology, evolutionary biology and conservation science. Accordingly, MPMs now exist for over 3000 species worldwide.

A numerical scheme for the optimal control of groundwater pollution
Numerical Methods for Partial Differential Equations, Volume 39, Issue 4, Page 3037-3063, July 2023., 2023 Abstract A scheme is proposed for the numerical study of optimal control problems related to groundwater quality management in the case of nonpoint‐source pollution. The corresponding state equation is a system of coupled nonlinear partial differential equations.

Optimal allocations with α‐MaxMin utilities, Choquet expected utilities, and prospect theory
Theoretical Economics, Volume 18, Issue 3, Page 993-1022, July 2023., 2023 The analysis of optimal risk sharing has been thus far largely restricted to nonexpected utility models with concave utility functions, where concavity is an expression of ambiguity aversion and/or risk aversion. This paper extends the analysis to α‐maxmin expected utility, Choquet expected utility, and cumulative prospect theory, which accommodate ...

Hidden Markov models: Pitfalls and opportunities in ecology
Methods in Ecology and Evolution, Volume 14, Issue 1, Page 43-56, January 2023., 2023 Abstract Hidden Markov models (HMMs) and their extensions are attractive methods for analysing ecological data where noisy, multivariate measurements are made of a hidden, ecological process, and where this hidden process is represented by a sequence of discrete states.

Correction to: Quantitative Approximation by Nonlinear Picard–Choquet, Gauss–Weierstrass–Choquet and Poisson–Cauchy–Choquet Singular Integrals [PDF]
Results in Mathematics, 2020 By using the concept of Choquet nonlinear integral with respect to a submodular set function, we introduce the nonlinear Picard–Choquet operators, Gauss–Weierstrass–Choquet operators and Poisson–Cauchy–Choquet operators with respect to a family of submodular set functions. Quantitative approximation results of the order $$\omega _{1}(f; t)_{\mathbb {R}}

Equipment Development Scheme Decision Based on IFS‐Choquet Integral Improved Matter Element Model
Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023 An optimized matter element decision method is proposed based on intuitionistic fuzzy set (IFS) and Choquet integral to solve the problems of equipment development scheme decision (e.g., the correlation of scheme attributes and the low decision reliability of evaluation results).

Estimating Household Preferences for Coastal Flood Risk Mitigation Policies Under Ambiguity
Earth's Future, Volume 10, Issue 12, December 2022., 2022 Abstract Risk mitigation policies (like dike rising) are essential to address increasing coastal flood risks due to global warming. Furthermore, the optimal level of risk mitigation policy should be determined by public preferences for risk reduction.

Optimising a nonlinear utility function in multi-objective integer programming [PDF]
, 2012 In this paper we develop an algorithm to optimise a nonlinear utility function of multiple objectives over the integer efficient set. Our approach is based on identifying and updating bounds on the individual objectives as well as the optimal utility ...

Einstein-Bianchi Hyperbolic System for General Relativity [PDF]
, 1997 By employing the Bianchi identities for the Riemann tensor in conjunction with the Einstein equations, we construct a first order symmetric hyperbolic system for the evolution part of the Cauchy problem of general relativity.
