A comparative study of the performance of seven- and 63-chip optical code-division multiple-access encoders and decoders based on superstructured fiber Bragg gratings [PDF]
, 2001 We report a range of elementary optical coding and decoding experiments employing superstructured fiber Bragg grating (SSFBG) components: first, we perform a comparative study of the relative merits of bipolar and unipolar coding: decoding schemes and ...

Journal of Engineering, Volume 2026, Issue 1, 2026.We investigate the performance limits of spectral amplitude coding optical code‐division multiple access (SAC‐OCDMA) systems from a receiver‐centric perspective. Existing approaches have focused largely on code design and uniform receiver architectures; however, these measures provide only partial mitigation and lead to rapid BER saturation as the ...

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.

Optical CDMA Networks with Bipolar Codes [PDF]
, 2001 In this communication we consider a dual wavelength scheme that allows the use of bipolar codes in optical code division multiple access networks. The performance of the system is derived for asynchronous and asynchronous users, and the results show that significant throughput improvements are achievable relatively to the conventional schemes relying ...

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 ...
