Integrability and Nonintegrability of Dynamical Systems
Integrability - an algebraic approach integrability - an analytic approach polynomial and quasi-polynomial vector fields nonintegrability Hamiltonian systems nearly integrable dynamical systems open
Morphological Control for High Performance, Solution‐Processed Planar Heterojunction Perovskite Solar Cells
Organometal trihalide perovskite based solar cells have exhibited the highest efficiencies to‐date when incorporated into mesostructured composites. However, thin solid films of a perovskite absorber
Perspectives on biological growth and remodeling.
Mechanics of the brain: perspectives, challenges, and opportunities
TLDR
It is shown that classical mechanical concepts including deformations, stretch, strain, strain rate, pressure, and stress play a crucial role in modulating both brain form and brain function.
High-quality bulk hybrid perovskite single crystals within minutes by inverse temperature crystallization
TLDR
A rapid crystal growth process to obtain MAPbX3 single crystals, an order of magnitude faster than previous reports, and the grown crystals exhibit transport properties and trap densities comparable to the highest quality MAPb X3 reported to date.
Component retention in principal component analysis with application to cDNA microarray data
Shannon entropy is used to provide an estimate of the number of interpretable components in a principal component analysis. In addition, several ad hoc stopping rules for dimension determination are
Recombination Kinetics in Organic-Inorganic Perovskites: Excitons, Free Charge, and Subgap States
Organic-inorganic perovskites are attracting increasing attention for their use in high-performance solar cells. Nevertheless, a detailed understanding of charge generation, interplay of excitons and
