Prevalence of Stroke and Diagnostic Performance of Emergency MRI in Acute Isolated Dizziness
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Stroke is frequently misdiagnosed in patients presenting with acute isolated dizziness; the optimal imaging modality for this population remains debated. This study aimed to determine the prevalence of stroke among patients with isolated dizziness and to assess the diagnostic accuracy of magnetic resonance imaging (MRI) and computed ...

The Efficient Coding of Speech: Cross-Linguistic Differences.
PLoS ONE, 2016 Neural coding in the auditory system has been shown to obey the principle of efficient neural coding. The statistical properties of speech appear to be particularly well matched to the auditory neural code.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

International Islamic University Malaysia Engineering Journal, 2010 Forward masking models have been used successfully in speech enhancement and audio coding. Presently, forward masking thresholds are estimated using simplified masking models which have been used for audio coding and speech enhancement applications.

Expanding Hereditary Spastic Paraplegias Limits: Biallelic SPAST Variants in Cerebral Palsy Mimics
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Hereditary spastic paraplegias (HSP) are rare neurodegenerative disorders marked by spasticity and lower limb weakness. The most common type, SPG4, is usually autosomal dominant and caused by SPAST gene variants, typically presenting as pure HSP.

Health‐Related Quality of Life in Rare Forms of Childhood‐Onset Hereditary Spastic Paraplegia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT We assessed health‐related quality of life (HRQoL) in 80 children with rare hereditary spastic paraplegias using the Caregiver Priorities and Child Health Index of Life with Disabilities and clinician‐reported outcomes. HRQoL was consistently reduced, particularly in relation to motor, autonomic, and bulbar symptoms.

Multilevel Delta Modulation with Switched First-Order Prediction for Wideband Speech Coding
Elektronika ir Elektrotechnika, 2018 In this paper a delta modulation speech coding scheme based on the ITU-T G.711 standard and the switched first-order predictor is presented. The forward adaptive scheme is used, where the adaptation to the signal variance is performed on frame-by-frame ...
