Mathematische Nachrichten, EarlyView.Abstract This paper is devoted to the approximation of two‐ and three‐dimensional Dirac operators HV∼δΣ$H_{\widetilde{V} \delta _\Sigma }$ with combinations of electrostatic and Lorentz scalar δ$\delta$‐shell interactions in the norm resolvent sense. Relying on results from Behrndt, Holzmann, and Stelzer‐Landauer [Math. Nachr.

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

Sustainable Development, EarlyView.ABSTRACT Food loss and waste (FLW) within agri‐food supply chains significantly impact the consumer economy, depleting natural resources and contributing to greenhouse gas emissions, thereby posing a critical challenge to sustainable development. Digital transformation is increasingly recognised as a key lever for reducing FLW in agri‐food supply ...

Small, EarlyView.This study presents a computational framework treating crystalline HOFs as adaptive atomic‐scale interfaces. Catenated HOFs preserve lattice stability under load while enabling auxetic deformation and reversible nonlinearity. The results provide direct evidence that supramolecular interactions govern macroscopic resilience and structural adaptability ...

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Different methods to prepare 1,7‐disubstituted tetradecaphenylheptasilanes are explored. The triflated heptasilane TfO‐(SiPh2)7‐OTf reacts with alkali metal halides to produce the 1,7‐dihalogenides X‐(SiPh2)7‐X (X = F, Cl, Br, I). The 1,7‐dihydrogen derivative H‐(SiPh2)7‐H is obtained with LiAlH4 or (i‐Bu)2AlH as reducing agents.

Characteristics and helium generation potential of ultra-deep marine shales as helium source rocks
Meitian dizhi yu kantanObjectiveLarge-scale, effective helium source rocks serve as a material basis for the formation of a helium-rich gas field. In the Weiyuan area, Sichuan Basin, the helium-rich gas reservoirs within the Dengying Formation exhibit helium source rocks ...
