Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

open access: yesAging and Cancer, EarlyView.
This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Data filtering based stochastic gradient algorithms for multivariable CARAR-like systems

open access: yesMathematical Modelling and Analysis, 2013
This paper considers identification problems for a multivariable controlled autoregressive system with autoregressive noises. A hierarchical generalized stochastic gradient algorithm and a filtering based hierarchical stochastic gradient algorithm are ...

On the Stability of Multivariate Trigonometric Systems

open access: yesJournal of Mathematical Analysis and Applications, 1999
Kadec's 1/4-theorem says that if \(\{\lambda_n: n \in \mathbb{Z}\}\) is a sequence of real numbers for which \(|\lambda_n - n|\leq L < 1/4\), then \(\{e^{i \lambda_n \omega}: n \in \mathbb{Z}\}\) forms a Riesz basis for \(L^2[-\pi, \pi]\). \textit{S. J. Favier} and the reviewer [Appl. Comput. Harmon. Anal. 2, No. 2, 160-173 (1995; Zbl 0829.46006)] and \

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Clinical Spectrum and Outcomes of SOX1 Antibody‐Associated Paraneoplastic Neurological Syndromes: A Chinese Cohort Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background SOX1 antibody‐positive paraneoplastic neurological syndromes (PNS) exhibit significant population‐specific clinical heterogeneity. While Western cohorts predominantly manifest Lambert‐Eaton myasthenic syndrome (65%–80%), comprehensive clinical characterization and treatment response data in Asian populations remain critically ...

A New Point of View in Multivariable Controller Tuning Under Multiobjective Optimization by Considering Nearly Optimal Solutions

open access: yesIEEE Access, 2019
In this paper, we present the adjustment of controller parameters using multiobjective optimization techniques. Unlike other works, where only the Pareto optimal solutions are considered, we also consider the set of nearly optimal solutions nondominated ...

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

open access: yesAnnals 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 ...

Effect of Dependency in Systems for Multivariate Surveillance [PDF]

open access: yesCommunications in Statistics - Simulation and Computation, 2009
Systems for multivariate on-line surveillance (e.g. outbreak detection), are investigated. Optimal systems for statistical surveillance are based on likelihood ratios. Three systems are compared; based on each marginal density, based on the joint density and based on the Hotelling's T2.
