The compact eighth-order of approximation difference schemes for fourth-order differential equation

Қарағанды университетінің хабаршысы. Математика сериясы
Local and nonlocal boundary value problems (LNBVPs) related to fourth-order differential equations (FODEs) were explored. To tackle these problems numerically, we introduce novel compact four-step difference schemes (DSs) that achieve eighth-order of ...

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

Accurate critical exponents from the optimal truncation of the $$\varepsilon $$ ε -expansion within the O(N)-symmetric field theory for large N

European Physical Journal C: Particles and Fields
The perturbation series for the renormalization group functions of the O(N)-symmetric $$\phi ^4$$ ϕ 4 field theory are divergent but asymptotic. They are usually followed by Resummation calculations to extract reliable results. Although the same features

Dementia Incidence in Individuals With Parkinson's Disease in the Framingham Heart Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Limited information exists on incident dementia in individuals with Parkinson's disease (PD) in US community‐based samples. We examined cognitive statuses and PD diagnoses of 183 individuals in the Framingham Heart Study (FHS) to establish incident dementia, mortality rates, associations with sex, age at PD onset, and education level.

Second Order Filter Distribution Approximations for Financial Time Series with Extreme Outliers [PDF]

Particle Filters are now regularly used to obtain the filter distributions associated with state space financial time series. Most commonly used nowadays is the auxiliary particle filter method in conjunction with a first order Taylor expansion of the ...

Diophantine approximation and beta-expansions over the field of formal Laurent series

Journal of Approximation Theory, 2013
\textit{Y. Bugeaud} [Math. Ann. 341, No. 3, 677--684 (2008; Zbl 1163.11056)] considered sets of numbers with prescribed irrationality measure in the middle-third Cantor set. Particularly, he proved the following result. Let \(K\) be the set of \(\psi\)-approximable real numbers, \[ K(\psi):=\biggl\{x\in\mathbb R:\biggl|x-\frac{p}{q}\biggr|1\).

A Systematic Comparison of Alpha‐Synuclein Seed Amplification Assays for Increasing Reproducibility

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α‐synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross‐study comparability and clinical translation. Here, we review α‐synuclein SAA methods and their performance across various biological matrices.

A kernel method for non-linear systems indentification - infinite degree volerra series estimation [PDF]

Volterra series expansions are widely used in analyzing and solving the problems of non-linear dynamical systems. However, the problem that the number of terms to be determined increases exponentially with the order of the expansion restricts its ...
