An approach to determine the easy axis of magnetic film by anisotropic magnetoresistance measurements.

A series of Ta/NiCo/Ta films was grown through DC-sputtering. During deposition, a constant magnetic field was applied along the substrate in different direction to induce different orientation of easy axis. Three different magnitudes of external fields were applied in the angle-dependent anisotropic magnetoresistance (AMR) measurements of the samples. Through an effective analysis, the angle-direction extracted via the intersection of three angle-dependent AMR curves was confirmed as the easy axis. Compare...

Is the joint-angle specificity of isometric resistance training real? And if so, does it have a neural basis?

There are suggestions that isometric resistance training (RT) produces highly angle-specific changes in strength with the greatest changes at the training angle, but these effects remain controversial with limited rigorous evidence, and the possible underpinning physiological mechanism(s) remain opaque. This study investigated the extent of angle-specific changes in strength and neuromuscular activation after RT in comparison to a control group.

Automated optical distance measurements for counting at a defined solid angle.

Two optical distance measurement devices have been compared for accurately defining the source-detector geometry of alpha-particle counters. The first consists of a travelling microscope with unifocal lens, to which a linear distance gauge is attached. The focusing is done by human eye. The second is a modern 3D coordinate measurement machine, equipped with a CMOS colour camera as the sensor. Focusing is performed automatically by software. With both devices, distance measurements of various drop-deposited ...

Effect of cavosurface angle beveling on the exposure angle of enamel prisms in different cavity sizes.

The quality of the micromechanical retention between the enamel prisms exposed through acid etching and adhesive system can be influenced by the relationship between the angle of the exposed enamel prisms and the external surface/restorative material. Therefore, the aim of the present study was to determine the influence of the enamel cavosurface beveling in different cavity sizes on the angle relation between enamel prisms and the restorative material. For this research, 30 human permanent molars were used...

Novel Formula to calculate 3-D Angle between Inflow Cannula and Device Body of HeartMate II LVAD.

The acute angle between inflow cannula and device body of HeartMate II left ventricular assist device (LVAD) is associated with device thrombosis. However, most studies utilized 2-dimensional (2D) angle obtained from chest X-ray (CXR), which is unlikely accurate. We aimed to create and validate a formula to estimate actual 3-dimensional (3D) angle.

Smartphone Aided Quantification of Iridocorneal Angle.

As the upgrading smartphone technology revolutionizes the field of Ophthalmic imaging, we put forward one more of its novel application. This article presents the possibility of iridocorneal angle estimation (ICA) through smartphone-captured images. Such measured inferior ICA (at 6'o clock position) was comparable to the anterior segment optical coherence tomography (ASOCT) measured trabecular iris angle at 500▒μ (TIA500) at 270° (P=0.06). They both had an excellent positive correlation (rho 0.81, P

Trailing limb angle is a surrogate for propulsive limb forces during walking post-stroke.

Propulsive deficits following stroke have been attributed to reduced plantarflexion moments and a reduced trailing limb angle. We sought to determine the validity of the trailing limb angle as a surrogate measure of the anterior ground reaction force, as well as to determine the anatomical landmarks for the trailing limb angle that best approximate the orientation of the ground reaction force.

Occipital and external acoustic meatus to axis angle: a useful predictor of oropharyngeal space in rheumatoid arthritis patients with atlantoaxial subluxation.

Dyspnea and/or dysphagia is a life-threatening complication after occipitocervical fusion. The occiput-C2 angle (O-C2a) is useful for preventing dyspnea and/or dysphagia because O-C2a affects the oropharyngeal space. However, O-C2a is unreliable in atlantoaxial subluxation (AAS) because it does not reflect the translational motion of the cranium to C2, another factor affecting oropharyngeal area in patients with rheumatoid arthritis (RA) who have reducible AAS. The authors previously proposed the occipital ...
