Physical Review Letters, 1994 We consider a system in which a classical oscillator is interacting with a purely quantum mechanical oscillator, described by the Lagrangian $ L = \frac{1}{2} \dot{x}^2 + \frac{1}{2} \dot{A}^2 - \frac{1}{2} ( m^2 + e^2 A^2) x^2 \>, $ where $A$ is a classical variable and $x$ is a quantum operator.

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract We present a decadal‐scale paleomagnetic analysis of a stalagmite collected from Shuixi Cave, southwest China, spanning 89−123 ka. Our findings include: (a) Magnetite is the dominant magnetic mineral, and paleomagnetic directions can be obtained via demagnetization; (b) Magnetic scanning at 0.1‐mm resolution captures key magnetic features ...

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.Alle Seltenerdelemente bilden bekanntlich tri‐ und auch di‐valente Verbindungen. Wenige tetra‐valente Verbindungen sind auch bekannt; kürzlich wurden die ersten Moleküle und Kristalle mit Praseodym(+5) synthetisiert. Der hier definierte atomare Ionisations‐Quotient IQ legt nahe, dass Ln(+4)‐Verbindungen mit geeigneten Liganden für fast alle 4f‐Elemente

Chaos in Optomechanical Systems Coupled to a Non-Markovian Environment
EntropyWe study the chaotic motion of a semi-classical optomechanical system coupled to a non-Markovian environment with a finite correlation time. By studying the emergence of chaos using the Lyapunov exponent with the changing non-Markovian parameter, we show

Advanced Science, Volume 13, Issue 2, 9 January 2026.The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

Memristive Chaotic Circuit for Information Processing Through Time
Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.A chaotic circuit that exploits the nonlinear characteristics of a memristive device is realized in hardware. The circuit response evolves through simple periodic, multiperiod, and chaotic regimes. The circuit also displays fading memory property. Finally, the circuit is used in a reservoir computing architecture to demonstrate nonlinear classification
