Late‐onset unexplained epilepsy as a risk factor for cognitive impairment and dementia: Protocol for a multi‐center prospective longitudinal observational study (ELUCID)

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Late‐onset unexplained epilepsy (LoUE), defined as epilepsy onset after age 55 without an obvious cause, is an important risk factor for dementia. Studies have shown that 10%–25% of individuals with LoUE develop dementia within 3–4 years following their first seizure.

Mechanisms and Applications of Casing Running Mechanics in CCUS Extended‐Reach Horizontal Wells

open access: yesEnergy Science &Engineering, EarlyView.
In this paper, the research on casing running is analyzed. By analyzing the stress and deformation of casing string with centralizer, the calculation model of friction, bending and centralizer pointing force in the process of horizontal down‐hole running of casing string is derived, and the friction between casing and running hole wall is solved by ...

Development of a Novel Modified Mean‐Line Approach for Performance Prediction of Axial Compressors

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT There is significant importance in accurate prediction of axial flow compressor characteristics at different conditions. Different techniques and models have been proposed for performance prediction of axial compressors. Because of its lower computational cost and high speed the meanline algorithm has been widely applied in preliminary design ...

Locally Adaptive Non‐Hydrostatic Shallow Water Extension for Moving Bottom‐Generated Waves

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study proposes a locally adaptive non‐hydrostatic model, which is based on the non‐hydrostatic extension of the shallow water equations (SWE) with a quadratic pressure relation, and applies it to wave propagation generated by a moving bottom. To obtain the locally adaptive model, we investigate several potential adaptivity criteria based on the ...

Scale, Skill‐Mix, and Access Implications of the Production of Appointments by Primary Care Practices in England

open access: yesHealth Economics, EarlyView.
ABSTRACT Primary medical care has traditionally been provided by small organisations. Recent policy developments in many countries have encouraged larger practices in the hope of benefiting from increasing returns to scale, but there is little research evidence to support this.

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

open access: yesHeat Transfer, EarlyView.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...

Information Flows, Stock Market Volatility and the Systemic Risk in Global Finance

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT Information flows are a theoretical explanation for stock market volatility, but controversy remains regarding how to measure them. Based on cross‐sectional and temporal properties of information flows, we decompose total trading volume into four types: cross‐country shocks and country‐specific shocks due to arrivals of private information ...
