However, both β2/3-ARs can also couple to G-inhibitory (Gi) proteins to attenuate β1-AR hyperactivation19. In this framework, activation of Gi-coupled signaling pathways, β2-ARs/protein kinase B (Akt) and β3-ARs/protein kinase G (PKG) have been confirmed as cardioprotective under ...
(1) A new class A4a* “communication grade” standard POF will be defined with improved parameters, more riented on market available fibers (160 dB/km loss at 650 nm, NA: 0.48 ± 0.02, bandwidth: 40 MHz·100m)(2) Multi core and GI-POF can be used as alternatives, if they are do...
Additionally, they are so common that it would be very\npunishing to disallow `any.toString()` or `any == true`, for example.\n\nNote that despite `Function` being a type, the semantics are close to identical\nto `dynamic`, and calls to an object that is typed `Function` will also...

For the repetition rate of 30 MHz and the pulse width of 200 fs, the evolution curve of the idler pulse energy was obtained by varying with the pump and signal pulse energy, predicting that there are linear growth, nonlinear amplification, and saturation zones in the DFG process (as shown ...
Figure 2. Activation and oligomerisation extents determined using NMR for different amino acids. (a) Exemplary 1H NMR spectrum (300 MHz) obtained from the GAVLPSAA mixture after 15 min of activation with CDI used to determine the activation extent of glycine and valine. (b) Exemplary proton-...
