Heavy‐Atom Tunneling at Room Temperature Revealed by Instanton Theory
Angewandte Chemie, EarlyView.Usually, tunneling does not play a significant role in chemical reactions except at low temperature, especially when heavy atoms are involved. However, using nonadiabatic instanton theory we find that heavy‐atom tunneling dominates the reaction mechanism for spin‐forbidden processes in the synthesis of strained organic molecules even at room ...

Gradient regularity for strongly singular or degenerate elliptic and parabolic equations
Bruno Pini Mathematical Analysis SeminarWe present recent advances in the regularity theory for weak solutions to some classes of elliptic and parabolic equations with strongly singular or degenerate structure.

Journal of Applied Polymer Science, EarlyView.SLA‐printed microneedles exhibit fabrication‐induced dimensional deviations that strongly influence their mechanical response. Comparison of nominal CAD, global as‐printed, and local critical‐section models shows that local tip‐region geometry provides the closest agreement with experimental instability loads, highlighting the importance of fabrication‐

Global Schauder Regularity and Convergence for Uniformly Degenerate Parabolic Equations
In this paper, we study the global Hölder regularity of solutions to uniformly degenerate parabolic equations. We also study the convergence of solutions as time goes to infinity under extra assumptions on the characteristic exponents of the limit ...

Null controllability of semilinear degenerate parabolic equations in bounded domains
Electronic Journal of Differential Equations, 2006 In this paper we study controllability properties for semilinear degenerate parabolic equations with nonlinearities involving the first derivative in a bounded domain of R. Due to degeneracy, classical null controllability results do not hold in general.

Convergence analysis of option drift rate inverse problem based on degenerate parabolic equation
Results in Applied MathematicsIn this paper, we study the convergence of the inverse drift rate problem of option pricing based on degenerate parabolic equations, aiming to recover the stock price drift rate function by known option market prices.

Ultrafast RF Spectrum Analyzer Assisted by Optical Short‐Time Fourier Transform
Advanced Physics Research, EarlyView.We present Recent efforts in an ultrafast RF spectrum analyzer based on the short‐time Fourier transform (STFT) at over 10 MHz frame rate and over 40GHz bandwidth to improve performance and support applications. All these efforts could inspire more innovative applications of temporal imaging modalities in the future.

The Interplay of Crystal‐Field Transitions and Exchange Spin Dynamics in a Ferrimagnet
Advanced Physics Research, EarlyView.Temperature‐dependent THz spectroscopy reveals strong hybridization between Yb3+ CEF excitations and Yb–Fe exchange dynamics in Gd3/2Yb1/2BiFe5O12. Near the magnetization compensation temperature, spectral weight is redistributed between the coupled modes, while the Yb–Fe exchange mode exhibits an anomalous redshift upon cooling due to CEF‐mediated ...

Quasiconformal mappings and degenerate elliptic and parabolic equations
Le Matematiche, 1987 In this paper two Harnak inequalities are proved concerning a degenerate elliptic and a degenerate parabolic equation. In both cases the weight giving the degeneracy is a power of the jacobian of a quasiconformal mapping.
