Optimizing subtraction-based approaches in time-domain diffuse optics by a time-window analysis

Diffuse optics measurements performed in the time domain provide the highest information level, but are plagued by a low spatial resolution and significant sensitivity to superficial regions (e.g., extracerebral changes). Here we compare the two main analysis methods (namely, sta...

Reservoir Computing perspective: dynamics, neuroscience, and physical systems

Reservoir computing (RC) has emerged as a versatile computational framework that combines the expressive power of complex dynamics with remarkably simple learning mechanisms. This perspective reviews the fundamentals of RC, where a reservoir transforms temporal inputs into rich d...

Barium gallo-germanate glasses co-activated with Cr3+/Er3+ and Cr3+/Er3+/Ln3+ (Ln = Yb, Ho) for near-infrared luminescence applications

Abstract Near-infrared luminescence properties of barium gallo-germanate glasses co-activated with Cr 3+ /Er 3+ and Cr 3+ /Er 3+ /Ln 3+ (Ln = Yb, Ho) have been studied for the first time. Compared to Cr 3+ /Er 3+ co-doped sample, near-infrared emission of Er 3+ at 1534 nm in Cr 3...
