Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Hip Morphology–Based Osteoarthritis Risk Prediction Models: Development and External Validation Using Individual Participant Data From the World COACH Consortium

Arthritis Care &Research, EarlyView.
Objective This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the Worldwide Collaboration ...

OPERATOR-VALUED MULTIPLICATION OPERATORS ON WEIGHTED FUNCTION SPACES

Demonstratio Mathematica, 2002
Let \(X\) be a completely regular Hausdorff space, \(E\) a Hausdorff topological vector space, \(V\) a Nachbin family of weights on \(X\), and \(CV_b(X,E)\) the weighted space of continuous \(E\)-valued functions on \(X\). Let \(B(E)\) be the vector space of all continuous linear mappings from \(E\) into itself, endowed with the topology of uniform ...

Validation of a Genetic Risk Score Combined With Clinical Variables for Predicting Pulmonary Fibrosis in Early Rheumatoid Arthritis

Arthritis Care &Research, EarlyView.
Objective Pulmonary fibrosis (PF) is a severe extra‐articular manifestation of rheumatoid arthritis (RA). This study aimed to externally validate a genetic risk score (GRS) and a combined risk score (CRS) for predicting the risk of RA‐associated PF in an independent cohort of patients with early RA.

Multiplication operators in Köthe–Bochner spaces

Journal of Mathematical Analysis and Applications, 2011
Let X be a Banach space and E an order continuous Banach function space over a finite measure mu. We prove that an operator T in the Kothe-Bochner space E(X) is a multiplication operator (by a function in L(infinity)(mu)) if and only if the equality T(g < f, x*> x) = g < T(f), x*> x holds for every g is an element of L(infinity)(mu), f is an element of

Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Cyclic vectors for multiplication operators.

Michigan Mathematical Journal, 1988
If \(E\) is a complex topological vector space and \(T\) a continuous linear transformation on \(E\), a vector \(x\in E\) is a cyclic vector for \(T\) if \(\{p(T)x: p\) a polynomial\(\}\) is dense in \(E\). If \(\mu\) is a compactly supported Borel measure on \(\mathbb C\), let \(X\) be the closed unit ball of \(L^{\infty}(\mu)\) and let \(X_ p\) be ...
