Permanent trading impacts and bond yields [PDF]

open access: yes, 2011
We analyze four years of transaction data for euro-area sovereign bonds traded on the MTS electronic platforms. In order to measure the informational content of trading activity, we estimate the permanent price response to trades. We find not only strong

The permanent magnet hypothesis: an intuitive approach to designing non-circular magnet arrays with high field homogeneity

open access: yesScientific Reports, 2023
Does the Halbach magnetization rotation rule that is used for designing circular magnet arrays for achieving the best homogeneity hold also for an elliptical or other non-circular cross-section?

Low-energy quantum string cosmology [PDF]

open access: yes, 1997
We introduce a Wheeler-De Witt approach to quantum cosmology based on the low-energy string effective action, with an effective dilaton potential included to account for non-perturbative effects and, possibly, higher-order corrections.

Design and Optimization of Halbach Permanent Magnet Array with Rectangle Section and Trapezoid Section [PDF]

open access: yesInternational Journal of Engineering, 2021
A novel Halbach permanent magnet array with rectangle section and trapezoid section is proposed and optimized in this paper. The analytical model of the premanent magnet segment is established based on the surface current method, which is numerically efficient and can be utilized to evaluate the magnetic field closely with the premanent magnet segment ...
