Dual-Gap Dual-Pole Composite Machine for Mechanical Rotor Position Estimation [PDF]
Position sensorless control has been widely studied for electrical rotor position estimation. However, because of the magnetic periodicity, mechanical rotor position sensorless control of multipole electric machine was hardly reported.

Quiescent Gap Solitons in Coupled Nonuniform Bragg Gratings with Cubic-Quintic Nonlinearity
We study the stability characteristics of zero-velocity gap solitons in dual-core Bragg gratings with cubic-quintic nonlinearity and dispersive reflectivity. The model supports two disjointed families of gap solitons (Type 1 and Type 2).

This article evaluates the scientific and commercial rationales for the synthesis of horsepox virus. I find that the claimed benefits of using horsepox virus as a smallpox vaccine rest on a weak scientific foundation and an even weaker business case that

AdS bulk locality from sharp CFT bounds
It is a long-standing conjecture that any CFT with a large central charge and a large gap ∆gap in the spectrum of higher-spin single-trace operators must be dual to a local effective field theory in AdS.
