A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Invertible extensions of symmetric operators and the corresponding generalized resolvents [PDF]
International Journal of Mathematical Analysis, 2014 In this paper we study invertible extensions of a symmetric operator in a Hilbert space $H$. All such extensions are characterized by a parameter in the generalized Neumann's formulas. Generalized resolvents, which are generated by the invertible extensions, are extracted by a boundary condition among all generalized resolvents in the Shtraus formula.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

On Fuzzy Soft Linear Operators in Fuzzy Soft Hilbert Spaces
Abstract and Applied Analysis, 2020 Due to the difficulty of representing problem parameters fuzziness using the soft set theory, the fuzzy soft set is regarded to be more general and flexible than using the soft set.

Strong Convergence of Iterative Algorithm for a New System of Generalized (⋅, ⋅) − -Cocoercive Operator Inclusions in Banach Spaces [PDF]
, 2020 We introduce and study a new system of generalized (⋅, ⋅)− -cocoercive operator inclusions in Banach spaces. Using the resolvent operator technique associated with (⋅, ⋅)− -cocoercive operators, we suggest and analyze a new generalized algorithm of ...

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

Analytic perturbation of generalized inverses [PDF]
, 2013 International audienceWe investigate the analytic perturbation of generalized inverses. Firstly we analyze the analytic perturbation of the Drazin generalized inverse (also known as reduced resolvent in operator theory). Our approach is based on spectral

The Stokes resolvent problem : optimal pressure estimates and remarks on resolvent estimates in convex domains [PDF]
, 2020 The Stokes resolvent problem −Δ+∇= λ u − Δ u + ∇ ϕ = f with div()=0 div ( u ) = 0 subject to homogeneous Dirichlet or homogeneous Neumann-type boundary conditions is investigated.
