Limit Cycles of Continuous–Discontinuous Piecewise Linear Hamiltonian Systems in ℝ2 Separated by the Curve y=sinx

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 2093-2097, February 2026.
ABSTRACT These last decades piecewise differential systems have been studied intensively, mainly due to their applications. Inside the study of the dynamics of these differential systems, the limit cycles, that is, the isolated periodic orbits inside the set of all periodic orbits of the system, play a main role.

Tracking Structural and Electron Spin Density Changes in a Cooperative Mn3+ Spin Crossover Complex at Atomic Scale via Low Temperature Solid‐State NMR

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The spin transition of a Mn(III) complex is investigated by tracking the evolution of the 1H and 13C NMR signals of individual sites under fast low‐temperature magic angle spinning conditions. The proposed experimental methodology combined with ab initio calculations of the paramagnetic NMR shifts provides a unique toolbox to study the electronic ...

Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

Testing a General Theory for Optimal Flowering Time in Deciduous Perennial Plants as a Function of Growing Season Length

Ecology Letters, Volume 29, Issue 2, February 2026.
Climate change affects both the start and duration of growing seasons, creating complex effects on optimal flowering timing that go beyond simple responses to earlier springs. Using optimal energy allocation theory, we found a nonlinear relationship between growing season length and optimal flowering time which was supported by two experiments with ...

Sustainability and Its Seven Sisters

Natural Resource Modeling, Volume 39, Issue 1, February 2026.
ABSTRACT There are many concepts of sustainability. Robert Solow argued that sustainability would consist of conserving human well‐being over the “very long run”, through the interactions of the environment and other stocks in human decisions and activity.
