Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose To compare early patient‐reported clinical outcomes of patient‐individual total knee arthroplasty (TKA) with individualized trochlear design versus robotic‐assisted TKA using off‐the‐shelf implants in patients with valgus knee phenotypes and pronounced femoral valgus (lateral distal femoral angle [LDFA] < 85°) at 3 and 12 months ...

IEEE Access, 2018 The existence of missing data severely affects the establishment of correct data mining model from the raw data. Unfortunately, most of the existing missing data prediction approaches are inefficient to predict missing data from multivariable time series

Noise Folding in Completely Perturbed Compressed Sensing
Journal of Applied Mathematics, 2016 This paper first presents a new generally perturbed compressed sensing (CS) model y=(A+E)(x+u)+e, which incorporated a general nonzero perturbation E into sensing matrix A and a noise u into signal x simultaneously based on the standard CS model y=Ax+e ...

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this second part of our series of papers, we develop an abstract framework suitable for de Rham complexes that depend on a parameter belonging to an arbitrary Banach space. Our primary focus is on spectral perturbation problems and the differentiability of eigenvalues with respect to perturbations of the involved parameters. As a byproduct,

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

A Sparsity Adaptive Algorithm for Wideband Compressive Spectrum Sensing
Dianxin kexue, 2014 Traditional spectrum sensing based on compressed sensing assumes that the sparsity is known, in fact,it is unknown and time-varying. To solve the problem, a sparsity adaptive algorithm for wideband spectrum sensing was proposed.

New Sufficient Conditions of Signal Recovery With Tight Frames via
IEEE Access, 2018 This paper discusses the recovery of signals that are nearly sparse with respect to a tight frame D by means of the l1-analysis approach. We establish several new sufficient conditions regarding the D-restricted isometry property to ensure stable ...

Shear Wave Elastography to Assess Respiratory Muscle Function in Congenital Myopathies
Muscle &Nerve, EarlyView.ABSTRACT Introduction/Aims Respiratory muscle dysfunction is prevalent in congenital myopathies and often leads to respiratory failure. Ultrasound shear wave elastography (SWE) measures tissue elasticity and has been proposed as an alternative to invasive measures of respiratory muscle contractility.
