Wonder why babies nap on some days but not on others? Or why older people wake up earlier? Mathematical modelling of sleep ...

A new study shows how math helps explain why babies nap erratically, teens stay up late, and older adults wake earlier.

Achieving high efficiency, long operational lifetime, and excellent color purity is essential for organic light-emitting ...

Oscillators come with instability, noise, and spurious emissions. Overcoming these requires advanced design, materials, and ...

Nonlinear optics is the study of how intense light interacts with matter. The optical response of a material usually scales linearly with the amplitude of the electric field. At high powers ...

The synchronous oscillator (SO) and the coherent phase-locked synchronous oscillator (CPSO) are universal multifunctional networks that track, synchronize, and amplify as much as 80 dB; improve SNR by ...

The phase determines the oscillation frequency, and gain is a criterion for oscillation to exist. The four poles in the loop equation each contribute –45° phase shift accumulating the required total ...

Conventional vehicle suspension systems, often relying on integer-order models with fixed damping coefficients, struggle to deliver optimal performance across diverse an ...
