Z-DNA duplexes are a particularly complicated test case for current force fields. We performed a set of explicit solvent molecular dynamics (MD) simulations with various AMBER force field parametrizations including our recent refinements of the ε/ζ and ...

The torsional and rotation–torsion spectra of CD2HOH
Journal of Molecular Spectroscopy, 2016Abstract The torsional and rotation–torsion spectra of the doubly deuterated species of methanol CD2HOH have been analyzed using submillimeter wave, terahertz, and far infrared spectra. 101 torsional subbands, with subband centers ranging from 2.3 to 626 cm−1, were assigned.

Curvature, Torsion, and Force Sensing in Continuum Robots Using Helically Wrapped FBG Sensors
IEEE Robotics and Automation Letters, 2016Due to their small size and flexibility, fiber Bragg grating (FBG) sensors have been integrated into needle-sized continuum robots for shape estimation and force measurement. The challenge in extending previous shape and force sensing technologies to pre-

General Relativity with Spin and Torsion: Foundations and Prospects
, 1976A generalization of Einstein's gravitational theory is discussed in which the spin of matter as well as its mass plays a dynamical role. The spin of matter couples to a non-Riemannian structure in space-time, Cartan's torsion tensor.

Torsion, Strain, and Temperature Sensor Based on Helical Long-Period Fiber Gratings
IEEE Photonics Technology Letters, 2018A novel fiber sensor, which enables us to simultaneously measure the torsion, strain, and temperature, is proposed and experimentally demonstrated, which is based on utilization of two successively cascaded helical long-period fiber gratings (TSC-HLPGs).

Torsion of the Appendix Mimicking Ovarian Torsion
Obstetrics & Gynecology, 2006Appendiceal torsion is rare and generally seen more frequently in children than adults. Untreated it can lead to necrosis, ulceration, and subsequent peritonitis.A middle-aged female presented with a 5-day history of cramping abdominal pain and nausea and vomiting. Abdominal wall guarding and rebound tenderness was noted on examination.

Sensorless Torsion Control of Elastic-Joint Robots With Hysteresis and Friction
IEEE transactions on industrial electronics (1982. Print), 2016Sensorless torsion control is proposed for elastic-joint robots, with the geared drives subject to hysteresis and friction nonlinearities. The concept of the so-called “virtual torsion sensor” uses the motor torque and velocity, inherently available in ...

Pediatric Ovarian Torsion: Spectrum of Imaging Findings.
Radiographics, 2017The accurate diagnosis of ovarian torsion is imperative, as loss of the ovary can have long-term consequences in terms of fertility. However, a nonspecific clinical presentation in conjunction with a highly variable imaging appearance makes the diagnosis

The Contribution of Different Femur Segments to Overall Femoral Torsion
American Journal of Sports Medicine, 2016Background: Femoral torsion is a critical parameter in hip and knee disorders. The unproven assumption is that the femoral neck exclusively contributes to the overall torsion of the femur.
