The Pattern and Stages of Atrophy in Spinocerebellar Ataxia Type 2: Volumetrics from ENIGMA‐Ataxia

open access: yesMovement Disorders, Volume 40, Issue 4, Page 651-661, April 2025.
Abstract Background Spinocerebellar ataxia type 2 (SCA2) is a rare, inherited neurodegenerative disease characterized by progressive deterioration in both motor coordination and cognitive function. Atrophy of the cerebellum, brainstem, and spinal cord are core features of SCA2; however, the evolution and pattern of whole‐brain atrophy in SCA2 remain ...

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

Multivariate Neural Network Operators: Simultaneous Approximation and Voronovskaja‐Type Theorem

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, the simultaneous approximation and a Voronoskaja‐type theorem for the multivariate neural network operators of the Kantorovich type have been proved. In order to establish such results, a suitable multivariate Strang–Fix type condition has been assumed.

A New Approach for the Fractional Rosenau–Hyman Problem by ARA Transform

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The primary aim of this research to establish the solution to time fractional Rosenau–Hyman problem (RHP) by utilizing a new approach including ARA transform and Daftardar–Gejji and Jafari iteration method (DGJIM). The fractional derivative is taken in Caputo sense.
