Book Description
We present an unitary dispersive model for the $\eta \to 3 \pi$ decay process based upon the Khuri-Treiman equations which are solved by means of the Pasquier inversion method. The description of the hadronic final-state interactions for the $\eta \to 3\pi$ decay is essential to reproduce the available data and to understand the existing discrepancies between Dalitz plot parameters from experiment and chiral perturbation theory. Our approach incorporates substraction constants that are fixed by fitting the recent high-statistics WASA-at-COSY data for $\eta \to \pi+̂ \pi-̂ \pi0̂$. Based on the parameters obtained we predict the slope parameter for the neutral channel to be $\alpha=-0.022\pm 0.004$. Through matching to next-to-leading order chiral perturbation theory we estimate the quark mass double ratio to be $Q=21.4 \pm 0.4$.

Book Description
One of the Time 100 Best Fantasy Books Of All Time Two men rebel together against tyranny—and then become rivals—in this first sweeping book of an epic fantasy series from Ken Liu, recipient of Hugo, Nebula, and World Fantasy awards. Hailed as one of the best books of 2015 by NPR. Wily, charming Kuni Garu, a bandit, and stern, fearless Mata Zyndu, the son of a deposed duke, seem like polar opposites. Yet, in the uprising against the emperor, the two quickly become the best of friends after a series of adventures fighting against vast conscripted armies, silk-draped airships, and shapeshifting gods. Once the emperor has been overthrown, however, they each find themselves the leader of separate factions—two sides with very different ideas about how the world should be run and the meaning of justice. Fans of intrigue, intimate plots, and action will find a new series to embrace in the Dandelion Dynasty.

Book Description
The model calculations considered here test the DWBA with a wide range of three-body models. Each of the calculations, however, considers only one or two aspects of the accuracy of the DWBA. The lack of overlap of the testing parameters limits the con clusions which can be drawn. This is particularly true with reference to the nucleon core potential where comparable parameters are rarely used. In spite of this limitation, we may make a few observations about the sensitivity of the model cross sections and the mechanism which produces an accurate DWBA. Specifically we may summarize the most important results as follows: 1) In these models the exact DWBA at low energies (E
