A novel angle on helical blade placement in trochanteric fractures – The axis-blade angle

Injury, 2019
For trochanteric fractures, helical blade placement is crucial to the prognosis of operations. Existing measurement methods used for blade placement include the Cleveland zone, the tip-apex distance (TAD), the calcar-referenced tip-apex distance (CalTAD), and the Parker's ratio. These methods all lack a direct view on blade direction. The current study

Optimization of helix angle for helical gear system

Journal of Mechanical Science and Technology, 2008
A method is presented to optimize the helix angle of a helical gear from the viewpoint of the transmission error, which is the deflection of the teeth due to the transmitted load. The deflection of the gear teeth is calculated by using the bending and shear influence function, which is formulated from the common formula for deflection obtained from FEM,

Decay of wide-angle helical texture in superfluid3He-A

Journal of Low Temperature Physics, 1982
In3He-A there exist two helical textures: one withl almost aligned with the flow for small magnetic fields compared to the current (roughly\(h \lesssim \sqrt {20{\text{j}}} \lesssim 1.2\) in dipole units) and another withl almost orthogonal to the flow for larger fields [h⩾(40/7)1/2j⩽1].

Tailoring Helicity Angle of Twisted Skyrmions in Multilayered Nanostructures

physica status solidi (RRL) – Rapid Research Letters, 2021
Twisted skyrimons (TSs) are intermediate states between Bloch skyrmions and Néel skyrmions, and can emerge in multilayered systems due to the competition between Dzyaloshinskii–Moriya interaction and magnetic dipole–dipole interaction. Herein, TSs are investigated in terms of helicity angle variation and layer dependence in both three layer and general

Helical CT Reconstruction with Large Cone Angle

2006 IEEE Nuclear Science Symposium Conference Record, 2006
In this work we suggest ways to incorporate redundant data into reconstruction for a range of helical pitches from 1-PI to 3-PI. For evaluation we use simulated data and real 256-slice anthropomorphic phantom data. With large cone angle reconstruction is very sensitive to the exactness of the algorithm.

Measurement of the Skyrmion Helicity Angle

2018
In this chapter, the measurement of the skyrmion helicity angle \(\chi \) by the REXS-based technique is presented. Before starting, we would like to clarify the nomenclature used here.

Magic Angles and Force Transmission in Helically Wrapped Worms

Integrative And Comparative Biology
Synopsis Many animal structures and appendages are pressurized, cylindrical, and helically wrapped with fibers. Squid tentacles, elephant trunks, echinoderm tube feet, notochords, arteries, and the bodies of sharks, nematodes, and annelids are all helically wrapped and their structural function depends on force transmission by this ...
