We demonstrate experimentally and theoretically (both analytically and numerically) a new type of spatial soliton: a rotating "propeller" soliton. This is a composite soliton made of a rotating dipole component jointly trapped with a bell-shaped component. We observe as much as 239 degrees of rotation over 13 mm of propagation (6.5 diffraction lengths).

Introduction PROPELLER [1] is a variant of multi-shot FSE technique, providing a high-resolution DWI with excellent immunity to offresonance. Its self-navigated nature around the center of K-space also allows for motion correction. The odd/even echo phase inconsistencies in the non-CPMG echo train were addressed using the “split-blade” method [2], where the blade width was reduced by a factor o...

We present our experience of bilateral total breast reconstruction using a double-sided extended thoracodorsal artery perforator propeller flap in a case series of 10 patients. Reconstruction was successfully achieved in all cases with few complications. The median time for surgery was 275 minutes (200-330), and the average implant size used was 350 cm(3) (195-650). We demonstrate how the exten...

The LDLR (low-density lipoprotein receptor) is a modular protein built from several distinct structural units: LA (LDLR type-A), epidermal growth factor-like and beta-propeller modules. The low pH X-ray structure of the LDLR revealed long-range intramolecular contacts between the propeller domain and the central LA repeats of the ligand-binding domain, suggesting that the receptor changes its o...

The flow field of an infinitely bladed propeller of disk loading proportional to (r/R) • (l-r/R) in an incompressible, inviscid fluid is expressed in terms of a series of Legendre functions. Numerical calculations have been carried out for the case n = 5« The radial velocity at r = R, and the shape of the stream surface passing through the periphery of the propeller disk are determined and comp...

This paper introduces a control scheme to vector thrust in marine cycloidal propellers with non-zero forward speed, despite the presence of measurement noise and current-like disturbances. Cycloidal utilize 360° thrust-vectoring provide agile maneuvering surface vessels like tugboats double ended ferries, but have yet be utilized present-day unmanned autonomous vehicles. work strategizes low-le...
