On Bernstein Polynomials Method to the System of Abel Integral Equations

Abstract and Applied Analysis, 2014
This paper deals with a new implementation of the Bernstein polynomials method to the numerical solution of a special kind of singular system. For this aim, first the truncated Bernstein series polynomials of the solution functions are substituted in the

Homotopy analysis transform method for solving Abel’s integral equations of the first kind

Ain Shams Engineering Journal, 2016
In this paper, by combined homotopy analysis method and Laplace transform method, we produce a new powerful method and named homotopy analysis transform method. By using this method, we solve first kind singular integral equations of Abel type. Also, the

Trajectories of child emotional and behavioural difficulties before and during the COVID‐19 pandemic in a longitudinal UK cohort

JCPP Advances, EarlyView.
Abstract Background There are substantial age‐related changes in emotional and behavioural problems over childhood. In order to establish the impact of the Covid‐19 pandemic on child emotional and behavioural problems, longitudinal designs which take into account age‐related trends are needed.

Projected Evolution of Climatic Aridity in Spain: Robust Signals and Model Uncertainties

International Journal of Climatology, EarlyView.
This study examines the projected evolution of climatic aridity in Spain throughout the 21st century, using the UNEP Aridity Index and CMIP6 simulations under different emission scenarios and global warming levels. Despite model biases, results show a general increase in aridity across the country, particularly in southern regions and the Canary ...

Properties of solutions for nonlinear Volterra integral equations [PDF]

, 2003
Some properties of non-locally bounded solutions for Abel integral equations are given. The case in which there exists two non-trivial solutions for such equations is also studied.

Doping‐Free Polymer Nanoparticle Engineering of n‐Type Organic Mixed Ion–Electron Conductors for Enhancement‐Mode Organic Electrochemical Transistors

Macromolecular Rapid Communications, EarlyView.
We report a nanoparticle formulation strategy for the ladder polymer BBL that enables undoped enhancement‐mode OECTs. Controlled reprecipitation with DBSA yields stable nanoparticles, and spray‐coating forms dense, well‐connected films. The resulting devices exhibit strongly enhanced electrochemical response and transconductance, establishing a ...

Considerations of race and ethnicity within rehabilitation studies for post COVID‐19 condition: A scoping review

PM&R, EarlyView.
Abstract Post COVID‐19 condition (PCC) or long COVID disproportionately affects racial and ethnic minority communities. There are a growing number of rehabilitation studies for PCC, however, it has yet to be determined whether existing studies take race and ethnicity into account in their study designs and whether existing rehabilitative approaches are

Machine‐learning approaches for characterizing the raindrop size distributions in Western Pacific tropical cyclones

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Long‐term disdrometer observations are utilized to derive Z–R relationships for ‐the Western Pacific tropical cyclones. A hybrid moment‐based approach is employed to determine the interrelationships among pairs of gamma distribution parameters. Enhanced estimates of rainfall rate and slope parameter are obtained using machine‐learning techniques ...
