Radiographic assessment of AO 44-B1 and -B2 ankle fractures

open access: yesJournal of the Foot & Ankle, 2021
Objective: To verify if there is a type of image that guides the surgeon in recommending surgical treatment for ankle fractures and assess whether this decision is associated with the evaluator’s age and experience, considering surgeons of different ...

A cascaded H-bridge BLDC drive incorporating battery management [PDF]

open access: yes, 2007
A multilevel BLDC drive is proposed using cascaded H-bridges with isolated sources to provide superior output waveforms and reduced current ripple whilst incorporating observer based SoC estimation.

Acta Plane—A New Reference for Virtual Orientation of Cone Beam Computed Tomography Scans: A Pilot Study

open access: yesApplied Sciences, 2023
Introduction: Cone Beam Computed Tomography (CBCT) scans should be digitally oriented using a reference plane before being evaluated for patient growth and treatment outcome. Current orientation planes are usually dependent on the Porion points.

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]

open access: yes, 2011
A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

Adaptive Fuzzy Backstepping Sliding Mode Control for a 3-DOF Hydraulic Manipulator with Nonlinear Disturbance Observer for Large Payload Variation

open access: yesApplied Sciences, 2019
The paper proposes an adaptive fuzzy position control for a 3-DOF hydraulic manipulator with large payload variation. The hydraulic manipulator uses electrohydraulic actuators as primary torque generators to enhance carrying payload of the manipulator ...

A comparative analysis of manual glenoid version measurement using two- and three-dimensional computed tomography imaging techniques [PDF]

open access: yesClinics in Shoulder and Elbow
Background Accurate measurement of glenoid version is essential for optimal implant positioning in shoulder arthroplasty. This study compared the accuracy and reliability of unformatted two-dimensional computed tomography (2D-CT), formatted 2D-CT, and ...

Observed Subdecadal Variations of European Summer Temperatures [PDF]

open access: yesGeophysical Research Letters, 2020
AbstractWe identify subdecadal variations in European summer temperatures in coupled and uncoupled century‐long reanalyses. Spectral analyses reveal significant peaks at 5–10 years in the midtwentieth century. The subdecadal variations show substantial amplitudes of ~1–1.5 °C, associated with extremely warm summers during their positive phases.
