Infants and Mobiles: Developing an Understanding of Cause and Effect
Developmental Science, Volume 29, Issue 4, July 2026.ABSTRACT In the mobile conjugate reinforcement paradigm, an infant's leg is connected to a mobile via a string, allowing the infant to move the mobile via moving their leg. Over a few minutes, infants exhibit an increase in the frequency of movement of the connected leg.

High-Rate Space-Time Coded Large MIMO Systems: Low-Complexity Detection and Channel Estimation
, 2009 In this paper, we present a low-complexity algorithm for detection in high-rate, non-orthogonal space-time block coded (STBC) large-MIMO systems that achieve high spectral efficiencies of the order of tens of bps/Hz.

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems
International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...

Dynamic Multifunctional Metasurfaces Based on Passive Cascade Structure
Electron, Volume 4, Issue 2, May 2026.A dynamic multifunctional metasurface is proposed in this paper. Unlike mainstream multifunctional metasurface based on programmable metasurfaces, it consists of two passive metasurfaces, presenting a significant cost advantage. By controlling the displacement, different functions such as beam steering, focusing, and OAM wave generation can be realized

People and Nature, Volume 8, Issue 5, Page 1419-1436, May 2026.Abstract Understanding how local communities perceive and prioritise ecosystem services (ES) across diverse ecological contexts is essential for improving protected area (PA) management. However, most studies focus on single ecosystems and lack cross‐ecological comparisons. This study aimed to explore how communities living in and around PAs in Ghana's
