Variational construction of homoclinics and chaos in presence of a saddle-saddle equilibrium
, 1998 We consider autonomous Lagrangian systems with two degrees of freedom, having an hyperbolic equilibrium of saddle-saddle type (that is the eingenvalues of the linearized system about the equilibrium are $\pm λ_1, \pm λ_2 $, $λ_1, λ_2 > 0$). We assume that $λ_1 > λ_2$ and that the system possesses two homoclinic orbits.

The Anatomical Record, EarlyView.Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Clinical Anatomy, EarlyView.Abstract Although the sternoclavicular joint shares structural similarities with the knee and hip joints as a diarthrodial joint, its biomechanics differ significantly due to its non‐weight‐bearing nature. Nevertheless, it is subject to considerable loading, leading to increased susceptibility to osteoarthritis, a prevalent condition characterized by ...

Polycyclic Aromatics as Promising Phosphorescence Materials
ChemistryEurope, EarlyView.This review focuses on the recent progress of polycyclic aromatic compounds (PACs)‐based phosphorescent materials. Their molecular structural characteristics as promising phosphors are highlighted, and the efficient strategies from molecular and aggregation levels have been illustrated systematically to promote the development of PACs with desirable ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Biodiesel production from waste cooking oil (WCO) has emerged owing to growing interest in sustainable energy sources. Geopolymers synthesized from industrial wastes, such as blast furnace slag (BFS), are promising catalysts because of their environmental benefits and catalytic properties.

eChem: Accelerated Method Development in Quantum Chemistry with Notebooks
Chemistry–Methods, EarlyView.The benefits of using Jupyter Notebooks to simplify and accelerate scientific code development are demonstrated using the practical example of the analytical molecular Hessian. The eChem project has been previously presented as an interactive platform for quantum and computational chemistry education [J. Chem. Educ. 100, 1664–1671].
