Machine Learning‐Driven Prediction of Microplastic Aging Processes and Environmental Risk Assessment Across Multi‐Media Systems

open access: yesAdvanced Science, EarlyView.
This perspective proposes a cohesive machine learning strategy to decode microplastic aging. It advocates for Federated Learning to dismantle global data silos and introduces the TRACE framework (TRansport, Aging, Corona, Ecotoxicity). By integrating physics‐informed modeling with causal discovery, this approach bridges the laboratory‐field gap to ...

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

open access: yesAdvanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

Near-threshold pion production in diproton reactions with polarised beams and target at ANKE-COSY

open access: yesEPJ Web of Conferences, 2012
An extensive experimental study of near-threshold pion production in diproton reactions is underway at the ANKE-COSY spectrometer (Jülich). The programme is aimed at isolating the four-nucleon-pion contact interaction term appearing in the XPT expansions

Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

open access: yesAdvanced Electronic Materials, EarlyView.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Fundamental theorems of extensional untyped $\lambda$-calculus revisited [PDF]

open access: yesComputer Science Journal of Moldova, 2015
This paper presents new proofs of three following fundamental theorems of the untyped extensional $\lambda$-calculus: the $\eta$-Postpo-nement theorem, the $\beta\eta$-Normal form theorem, and the Norma-lization theorem for $\beta\eta$-reduction.

Nontangential limit theorems for normal mappings [PDF]

open access: yesPacific Journal of Mathematics, 1988
In Ann. Acad. Sci. Fenn., Ser. A1 280, 17 p. (1960; Zbl 0095.058), \textit{F. Bagemihl} and \textit{W. Seidel} posed the following question: Given a sequence \(\{z_ n\}\) in the open unit disc \(\Delta\) converging to some \(\zeta\in \partial \Delta\) and a meromorphic function f defined on \(\Delta\) such that \(\lim _{n\to \infty} f(z_ n)=c\) for ...

Teichmüller inequalities without coefficient normalization

open access: yes, 1971
Teichmüller’s relation between the coefficients of extremal schlicht functions and quadratic differentials is extended. The coefficient normalization hypothesis in his theorem is dropped with the result that the new coefficient relations become more ...
