An Angle Recognition Algorithm for Tracking Moving Targets Using WiFi Signals with Adaptive Spatiotemporal Clustering

Sensors, 2021
An angle estimation algorithm for tracking indoor moving targets with WiFi is proposed. First, phase calibration and static path elimination are proposed and performed on the collected channel state information signals from different antennas.

Neural Assimilation and Accommodation in Trilinguals: An fMRI Study at 7 T

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
Using brain activation and representational similarity analysis at 7 T‐MRI, this study demonstrated that the trilingual brain flexibly modulated neural assimilation and accommodation. While Chinese and English shared highly similar neural representations, Japanese engaged distinct patterns, highlighting script‐driven effects on multilingual neural ...

Gaussian Channel Model for Mobile Multipath Environment

EURASIP Journal on Advances in Signal Processing, 2004
A model of an angle-spread source is described, termed the “Gaussian channel model” (GCM). This model is used to represent signals transmitted between a user equipment and a cellular base station.

Mineralogy, mineral chemistry, and redox equilibria in ten aggregate particles from asteroid Bennu

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1905-1927, August 2026.
Abstract Examination of 10 Bennu aggregate particles has revealed the presence of many phases which taken together can provide constraints on the oxygen fugacity (fO2) of Bennu samples. Phyllosilicates (saponite and serpentine), carbonates, oxides (magnetite, chromite), sulfides (pyrrhotite, pentlandite), phosphate (hydroxyapatite, Na‐Mg‐phosphate ...

Direct Observations of Large‐Scale Wave Structure and Post‐Sunset Rise of the Ionosphere in the Generation of Equatorial Spread F

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large‐scale wave structure (LSWS) and the post‐sunset rise (PSSR) are two key factors in the generation of equatorial spread F (ESF). In this study, we reported continuous and direct observations of LSWS and PSSR and their effects on seeding ESF by Sanya incoherent scatter radar (SYISR) and ionosonde in September–October 2024.

Osteoarthritis: Epidemiology, Diagnosis, and Treatment

MedComm, Volume 7, Issue 7, July 2026.
Osteoarthritis (OA) is a multifactorial degenerative joint disease and a leading cause of disability worldwide. This graphical abstract summarizes the epidemiology, diagnostic strategies, and therapeutic approaches of OA. OA development is driven by aging, metabolic dysregulation, and mechanical stress, leading to progressive joint degeneration ...
