Ionospheric Vertical Plasma Drifts Over South America: Long‐Term Multi‐Instrument Observations and TIEGCM and WACCM‐X Evaluations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present the first comprehensive multi‐instrument climatological study of quiet‐time equatorial F‐region vertical plasma drifts across South America, a region where the magnetic declination angle varies significantly. Our analysis of well‐established long‐term ground‐based data sets from the Jicamarca incoherent scatter radar spanning 1968 ...

Experiences of parents of children with special needs: Educational services, challenges and recommendations from parents' perspectives

British Journal of Special Education, Volume 53, Issue 2, Page 200-213, June 2026.
Abstract Parents of children with special needs in Nigeria are faced with several challenges. In most cases, decisions are taken without their active involvement, despite them being the primary carers for their children with special needs. This research utilised a qualitative research design with fifteen participants to understand parents' perspectives

How Stock Market Participants Use Generative Artificial Intelligence: Evidence from User‐Platform Interaction Data

Journal of Accounting Research, Volume 64, Issue 3, Page 1375-1426, June 2026.
ABSTRACT This paper provides descriptive evidence on how stock market participants use Generative Artificial Intelligence (GenAI) to process investment‐related information. Using a data set of 1.7 million stock‐related queries from one of China's largest GenAI platforms during the first half of 2024, we document that user queries address a wide range ...

Outage Probability in a Multi-Cellular Network Using Alamouti Scheme

, 2010
In this paper we analyze the performance of a downlink single user multi-cellular multiple inputs single output (MISO) system using the Alamouti code. We derive, for the first time, an analytical expression of the cumulative distribution function of the ...
