Journal of Raman Spectroscopy, EarlyView.We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Laser &Photonics Reviews, EarlyView.In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

The Monterey Event and the Paleocene‐Eocene Thermal Maximum
Geophysical Monograph Series, Page 401-416., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Predicting Infrared Optical Properties of Materials Using Machine Learning Interatomic Potentials
Materials Genome Engineering Advances, EarlyView.This work proposes a new fast computing framework for infrared reflectance spectra, MTP‐FIRE, based on machine learning potential, which can achieve the same accuracy as the existing first‐principles calculation, but can be two orders of magnitude faster on average.

Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.
