Optimising Connectivity in Deep‐Sea MPA Networks for Nephrops norvegicus Recovery in NW Mediterranean Sea

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
In the NW Mediterranean, where the Norway lobster (Nephrops norvegicus) is both ecologically and economically important, larval connectivity in an existing network of Fishery No‐Take Zones was estimated using Lagrangian transport simulation informed by species‐specific habitat models.

New Types of Doubly Periodic Standing Wave Solutions for the Coupled Higgs Field Equation

open access: yesAbstract and Applied Analysis, 2014
Based on the Hirota bilinear method and theta function identities, we obtain a new type of doubly periodic standing wave solutions for a coupled Higgs field equation.

Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response

open access: yesLaser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.

Classical Higgs fields on gauge gluon bundles

open access: yesEPJ Web of Conferences, 2016
Classical Higgs fields and related canonical conserved quantities are defined by invariant variational problems on suitably defined gauge gluon bundles. We consider Lagrangian field theories which are assumed to be invariant with respect to the action of

Estimation of Mesoscale Momentum Flux Frequency Spectra in the Mesosphere and Lower Thermosphere Using Multistatic Specular Meteor Radar Wind Fields

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract A spectrally resolved observational methodology is introduced to estimate mesoscale momentum flux frequency spectra in the mesosphere and lower thermosphere (MLT). The method is applied to four‐dimensional wind fields reconstructed with the physics‐informed neural network approach called the Hydrodynamic Point‐wise Environment Reconstructor ...

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical Finance, Volume 36, Issue 4, Page 804-825, October 2026.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

A Model of Strategic Sustainable Investment

open access: yesMathematical Finance, Volume 36, Issue 4, Page 771-803, October 2026.
ABSTRACT We study a problem of optimal irreversible investment and emission reduction formulated as a nonzero‐sum dynamic game between an investor with environmental preferences and a firm. The game is set in continuous‐time on an infinite‐time horizon.

The Jacobi field of a L\'evy process

open access: yes, 2002
We derive an explicit formula for the Jacobi field that is acting in an extended Fock space and corresponds to an ( R -valued) L??vy process on a Riemannian manifold. The support of the measure of jumps in the L??vy???Khintchine representation for the L??vy process is supposed to have an infinite number of points. We characterize the gamma, Pascal, and

Dam Management in the Era of Climate Change

open access: yesMathematical Finance, Volume 36, Issue 4, Page 870-895, October 2026.
ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

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.
