NALA: a Nesterov accelerated look-ahead optimizer for deep learning [PDF]
PeerJ Computer ScienceAdaptive gradient algorithms have been successfully used in deep learning. Previous work reveals that adaptive gradient algorithms mainly borrow the moving average idea of heavy ball acceleration to estimate the first- and second-order moments of the ...

Convergence results for families of univalent mappings on the unit ball in C^n
Annales Academiae Scientiarum Fennicae Mathematica, 2016 Summary: Let \(\widetilde{S}^t_A(\mathbf{B}^n)\) be the family of normalized univalent mappings on the Euclidean unit ball \(\mathbf{B}^n\) in \(\mathbf{C}^n\), which have generalized parametric representation with respect to time-dependent operators \(A\in\widetilde{\mathcal{A}}\), where \(\widetilde{\mathcal{A}}\) is a family of measurable mappings ...

Local convergence for multi-point-parametric Chebyshev-Halley-type methods of high convergence order
, 2015 We present a local convergence analysis for general multi-point-Chebyshev-Halley-type methods (MMCHTM) of high convergence order in order to approximate a solution of an equation in a Banach space setting.

Advanced Science, EarlyView.An “Interface Reactor” strategy boosts simulation stability by 2–3 orders of magnitude, enabling stable 100 ns molecular dynamics of electrode‐electrolyte interfaces. Distinct SEI formation mechanisms are revealed: mixed co‐formation in carbonates versus surface‐energy‐controlled NaF crystallization in ethers. Metadynamics simulations further elucidate

Phase‐Dependent Oxygen Defect Energetics in Epitaxial NbN/AlN/NbN Films
Advanced Science, EarlyView.Phase dependent oxygen defect energetics in epitaxial δ‐NbN/AlN/δ‐NbN and β‐Nb2N/AlN/β‐Nb2N trilayers. Atomic‐scale analysis and first‐principles calculations reveal distinct oxygen incorporation pathways across NbN polymorphs. Layer resolved defect formation energies show that O is energetically more favorable within δ‐NbN electrodes, whereas in β ...

Advanced Science, EarlyView.A Sr‐free air electrode for high‐temperature solid oxide cells is designed by independently tailoring electronic conduction, ionic transport, and surface catalysis using complementary Sr‐free phases and infiltrated nanocatalysts. It delivers performance comparable to state‐of‐the‐art Sr‐containing electrodes while completely suppressing Cr‐induced ...
