摘要:Understanding nonadiabatic carrier-lattice interactions at the atomic scale remains a fundamental challenge, yet these processes govern energy transfer in materials and ultimately set limits in microelectronics. We combined attosecond core-level transient absorption spectroscopy with many-body theory to uncover how nonadiabatic electron-phonon coupling drives ultrafast relaxations in a titanium-carbide MXene. Phonon-driven changes in carrier localization modulated local field effects (LFEs), y...

摘要:Visceral pain disorders, such as irritable bowel syndrome, exhibit a marked female prevalence. Enhanced signaling between enterochromaffin (EC) cells in the gut epithelium and mucosal sensory nerve fibers likely contributes to this sex bias. We identified an estrogen-responsive paracrine pathway in which two enteroendocrine cell types, peptide YY (PYY)-expressing L cells and serotonergic EC cells, communicate to increase gut sensitivity in females. We demonstrate that estrogen signaling up-reg...

摘要:We provide a comprehensive assessment of the economic benefits and costs of global methane emissions abatement, anchored on the Global Methane Pledge. We use an integrated assessment model to estimate avoided climate damages at the global and country levels, including quantification of tipping points and risk. We further estimate air-quality cobenefits and methane abatement costs. We find that global methane action would be highly beneficial, yielding a benefit-cost ratio of at least six. It w...
