Monitorização da profundidade anestésica e prevenção do delirium pós-operatório
O delirium pós-operatório é uma complicação neuropsiquiátrica associada a desfechos clínicos desfavoráveis, especialmente em pacientes idosos submetidos a procedimentos cirúrgicos. A monitorização da profundidade anestésica por eletroencefalografia tem sido investigada como estra...

Residual Modulation Frequency Induced Phase-Drift Noise in Photoacoustic Ring-Down Spectroscopy
Abstract Photoacoustic ringdown spectroscopy (PARS) provides a transient readout route for rapid photoacoustic sensing, but its stability is limited by low-frequency amplitude fluctuations that are not fully explained by conventional laser-power drift, detector noise, or environm...

Numerical Evaluation of the Coupling Between Several Directional Coupler Designs
Background Power division, switching, modulation, and wavelength multiplexing in integrated photonics are made possible via directional couplers. Nonlinear effects, material characteristics, and waveguide geometry all affect how they couple. Because of their microstructure claddi...
