Optimized Long‐TE 1H sLASER MR Spectroscopic Imaging at 3T for Separate Quantification of Glutamate and Glutamine in Glioma

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Glutamate and glutamine are critical metabolites in gliomas, each serving distinct roles in tumor biology. Separate quantification of these metabolites using in vivo MR spectroscopy (MRS) at clinical field strengths (≤ 3T) is hindered by their molecular similarity, resulting in overlapping, hence indistinguishable, spectral peaks ...

Theoretical Kinetics Study of the OH + CH3SH Reaction Based on an Analytical Full‐Dimensional Potential Energy Surface

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT Based on a recently developed full‐dimensional analytical potential energy surface, named PES‐2024, which was fitted to high‐level ab initio calculations, three different kinetic theories were used for the computation of thermal rate constants: variational transition state theory (VTST), quasi‐classical trajectory theory (QCT) and ring polymer

Dynamics of Dissipative Cavity Solitons in a Lattice Trap

Laser &Photonics Reviews, EarlyView.
This work presents a generalized analytical model elucidating the dynamics of dissipative solitons in dual‐frequency‐pumped Kerr‐nonlinear cavities. The unified framework predicts new phenomena and expounds hitherto unexplained experiments covering hysteresis, Arnold tongues, and existence region of all‐optical dissipative time crystals.

1 PHz of Coherent Bandwidth from a Compact Fiber Device

Laser &Photonics Reviews, EarlyView.
A coherent comb spectrum with an unprecedented bandwidth of 1 PHz, spanning from the deep ultraviolet (280 nm) to the mid‐infrared (2700 nm), is generated by a compact fiber device. The integrated, novel pulse purification technology enables broadband dispersion control and the synthesis of low‐noise, single‐cycle near‐infrared pulses with a clean ...
