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 ...

Nanometric Faujasite (FAU) Zeolite Ion‐Exchanged With Metal Ions for Hemostatic and Antimicrobial Applications: A Thromboelastographic and Microbiological Study

Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Faujasite nanozeolite (NanoFAU) and its ion‐exchanged forms (Ag+, Ba2+, Ca2+, Mg2+) were synthesized and characterized to assess their biomedical potential. NanoFAU‐Ca showed superior hemostatic activity, while NanoFAU‐Ag exhibited strong antimicrobial effects against S. aureus and C. albicans.

Synergistic Photophysical and Mechanical Enhancement in Europium Supramolecular Hydrogel by Incorporating Gd(DPA)3 Complex (DPA = Dipicolinate)

ChemistryOpen, Volume 15, Issue 5, May 2026.
Lanthanide‐based hydrogels incorporating Ln(DPA)3 complexes are synthesized and exhibit enhanced mechanical and luminescent properties. Increased complex concentration improves stiffness and emission intensity without altering coordination symmetry. Computational insights reveal preserved structural features, while lifetime changes highlight hydrogel ...

Pharmacological inhibition of hydroxysteroid 11‐beta dehydrogenase type 1 (11‐βHSD1) after myocardial infarction preserves cardiac function in a translational mini‐pig model

British Journal of Pharmacology, Volume 183, Issue 10, Page 2236-2255, May 2026.
Abstract Background and Purpose Plasma glucocorticoids increase acutely after MI, thereafter tissue levels are amplified selectively within cells expressing 11‐ßhydroxysteroid dehydrogenase type 1 (11‐ßHSD1) that regenerates active glucocorticoids from circulating metabolites.

Intersymbol Decorrelating Detector for Asynchronous CDMA Networks with Multipath

EURASIP Journal on Wireless Communications and Networking, 2005
Most reported multiuser detection techniques for CDMA systems need the channel estimation including the delay spread and the parameters of the multipath channel of the desired user. This paper proposes an intersymbol decorrelating detector that makes use

Multiple-antenna-aided OFDM employing genetic-algorithm-assisted minimum bit error rate multiuser detection

, 2005
The family of minimum bit error rate (MBER) multiuser detectors (MUD) is capable of outperforming the classic minimum mean-squared error (MMSE) MUD in terms of the achievable bit-error rate (BER) owing to directly minimizing the BER cost function.
