Integer-Valued Moving Average Modelling of the Number of Transactions in Stocks [PDF]
The integer-valued moving average model is advanced to model the number of transactions in intra-day data of stocks. The conditional mean and variance properties are discussed and model extensions to include, e.g., explanatory variables are offered ...

SPG4 and Dementia: Expanding the Clinical Spectrum
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

Global Search Strategies for Solving Multilinear Least-Squares Problems
Sultan Qaboos University Journal for Science, 2012 The multilinear least-squares (MLLS) problem is an extension of the linear least-squares problem. The difference is that a multilinear operator is used in place of a matrix-vector product.

Asymptotic properties of weighted least squares estimation in weak parma models [PDF]
The aim of this work is to investigate the asymptotic properties of weighted least squares (WLS) estimation for causal and invertible periodic autoregressive moving average (PARMA) models with uncorrelated but dependent errors. Under mild assumptions, it

Study of interpolating moving least squares method on fitting potential energy surface [PDF]
Dissertation supervisor: Dr. Donald L. Thompson.Includes vita.Interpolating moving least-squares method (IMLS) is a highly accurate fitting method. There are a lot of studies on how to use IMLS to fit potential energy surfaces (PESs).

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Anisotropic Diffusion in Mesh-Free Numerical Magnetohydrodynamics
, 2016 We extend recently-developed mesh-free Lagrangian methods for numerical magnetohydrodynamics (MHD) to arbitrary anisotropic diffusion equations, including: passive scalar diffusion, Spitzer-Braginskii conduction and viscosity, cosmic ray diffusion ...

Moving Weighted Least Squares implementation in MoFEM
, 2019 This report contains a brief description of of Moving Weighted Least Squares Approximation implementation in MoFEM. The approach is used for projecting data between different finite element meshes or ct scan data. The performance of the approach is demonstrated on two examples.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.
