An Inverse Source Technique as a Preliminary Tool to Localize Persons in Indoor Spaces

Mathematical Methods in the Applied Sciences, Volume 49, Issue 1, Page 304-320, 15 January 2026.
ABSTRACT This paper considers an inverse heat source localization problem with applications to indoor person localization from temperature measurements. In particular, this inverse problem consists in the reconstruction of the intensity and position of heat sources from observed temperature data.

Volterra integral equations: the singular case

Hokkaido Mathematical Journal, 2003
The authors are concerned with the investigation of singular Volterra integral equations of the form \[ y(t)= \int^t_0 k(t, s) f(s,y(s))\,ds,\quad t\in [0,T]. \] The singularity feature appears in the nonlinearity \(f(t,y)\), which may admit a nonregular behavior at \(y= 0\).

TVB C++: A Fast and Flexible Back‐End for The Virtual Brain

Advanced Science, Volume 13, Issue 2, 9 January 2026.
TVB C++ is a streamlined and fast C++ Back‐End for The Virtual Brain (TVB), designed to make it as flexible as TVB, and FAST. Another pillar is to be fully compatible with TVB so easy bindings can be created from Python. Users can easily configure TVB C++ to execute the same code but with enhanced performance and parallelism.

Admissibility and Nonlinear Volterra Integral Equations [PDF]

Proceedings of the American Mathematical Society, 1970
Nonlinear perturbations of linear Volterra integral equations are studied in an abstract setting which contains and generalizes some earlier results on the same problem. The perturbed problem is first written as a variation of constants equation on a Fréchet space.

Forced Periodic Reactor Operation Applied to Methanol Synthesis

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
Forced periodic operation of methanol synthesis is studied theoretically and experimentally considering an industrial Cu/ZnO/Al2O3 catalyst. The nonlinear frequency response method and rigorous mathematical optimization predict attractive forcing parameters.

Phytochemical diversity and seasonality are associated with a critical transition in plant–herbivore network structure

Ecology, Volume 107, Issue 1, January 2026.
Abstract Understanding critical transitions in ecological systems is fundamental for addressing various natural phenomena, from population outbreaks to sudden ecosystem collapses. Ecological interactions are key drivers of these transitions, and theory suggests that the networks formed by these interactions can undergo their own critical transition. By

Volterra-Choquet integral equations

Journal of Integral Equations and Applications, 2019
The paper deals with the Volterra-Choquet equation, which is the classical Volterra equation of the second kind in which the Lebesgue type integral \(\int ds\) is replaced by the Choquet integral \((C)\int d\mu(s)\). The author considers the following equation \[ \varphi(x) = f(x) +\lambda\cdot (C)\int_{a}^{x} K(x,s,\varphi(s)) d\mu(s), \quad x\in [a,b]
