Complementary Therapies in Pain Management in Hospitalized Patients: A Scoping Review
Nursing Forum, Volume 2026, Issue 1, 2026.Background The pain is influenced by various biopsychosocial factors. Its presence can negatively affect both the physiological and psychological states of an individual. Nonpharmacological strategies have gained prominence by complementing, rather than replacing, pharmacological treatment.

EURASIP Journal on Advances in Signal Processing, 2003 The goal of this paper is to compare the performance of the linear minimum mean square error (MMSE) detector for a class of code division multiple access (CDMA) systems in time and frequency selective channels. Specifically, we consider direct sequence (

, 2006 There has been a recent upsurge of interest in applying Code Division Multiple Access (CDMA) techniques to optical networks. Conventional spreading codes for OCDMA, known as optical orthogonal codes (OOC) spread the signal in the time domain only, which often results in the requirement of a large chip rate.

Solar‐Driven Photocatalytic N2 Reduction to Ammonia Using Plasmonic Au@NiZIF‐8 MOF Hybrids
Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.AuNSTs@NiZIF‐8 core‐shell photocatalysts are engineered for plasmon‐driven N2 reduction under visible light. The enhancement of Ni absorption, improving the efficiency of the metal center catalysts through the nanoantenna effect of the AuNP, combined with the injection of hot electrons and holes into the orbitals of the Ni atoms, results in a hybrid ...
