Epilepsy detection using detrended fluctuation analysis

, 2009
Epilepsy is a disorder of the central nervous system characterized by the loss of consciousness and convulsions. If some early warning signal of an upcoming seizure (diagnosis of preictal period) could be detected, proper treatment could be applied to ...

A new piece in the puzzle: The palaeoecological significance of bryozoans over 7000 years in Daidokutsu Cave (Okinawa, Japan)

Journal of Quaternary Science, EarlyView.
ABSTRACT Submarine caves are cryptic, climatically sensitive habitats with long‐term ecological dynamics that are poorly understood. We present the first palaeoecological analysis of bryozoans from Daidokutsu Cave (Okinawa, Japan), based on a sediment core spanning approximately the last 7000 years.

Eroding Confidence in Gully Location Risk Prediction in Mine Pit Rehabilitation

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how rehabilitation measures, such as landform shaping, and surface finishes impact gully erosion risk could assist in designing less erosive rehabilitation. In this study we use high resolution digital elevation models of rehabilitated mine pits to explore risk factors for gully formation.

Kinematic Features of Voluntary and Involuntary Head Movements in Cervical Dystonia

Movement Disorders, EarlyView.
Abstract Background Cervical dystonia (CD) has a varied motor presentation, combining abnormal postures with complex involuntary head movements. Classification of these motor patterns remains imprecise, relying on descriptive terminology without robust definitions. Objectives To provide a kinematically‐grounded description of the motor phenomenology of

R/S analysis and DFA: finite sample properties and confidence intervals [PDF]

We focus on finite sample properties of two mostly used methods of Hurst exponent H estimation – R/S analysis and DFA. Even though both methods have been widely applied on different types of financial assets, only several papers have dealt with finite ...

Sensing in Sacral Neuromodulation: Objective, Individualized Stimulation Response Thresholds Directly From the Lead

Neurourology and Urodynamics, EarlyView.
ABSTRACT Objectives Sacral neuromodulation (SNM) therapy today relies on visually observed motor responses (e.g., anal bellows contraction, toe flexion) and subjective patient feedback (pelvic region sensations) to optimize lead placement and perform device programming.
