El Nino-Southern Oscillation (ENSO) neutral conditions are likely in the Northern Hemisphere summer of 2025, with a 56% chance in August-October, the U.S. Climate Prediction Center said, meaning ...

Many people who get analog electronics still struggle a bit to design oscillators. Even common simulators often need a trick ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

This approach provides stable, expressive, and computationally efficient predictions without overly restrictive conditions on the model parameters. The work is available on the arXiv preprint server.

Energy drain on micromechanical resonators is always compensated by energy gain from external sources during operation. Here, Chenet al. show a strategy that can sustain stable oscillations by ...

The finding of a significant sea-level oscillation 120,000 years ago is in sharp contrast to the last 5,000 years, where sea level has been relatively stable.

This image represents a circular hydraulic jump produced by the impact of a 0.9 mm wide water jet on a Plexiglas disk. The flow rate is 2.1 mL/s. Credit: Physical Review Letters (2023). DOI: 10. ...

We can call such oscillation phase-controlled operation, while the conventional oscillation is delay-controlled operation. As a result, the cavity modes of OEPO are not restricted by the cavity delay.

Crystal Overtone and Spurious Modes: Crystals can offer many resonant modes that can be exercised by proper design of crystal oscillator. The major response and mostly desired one is the “Fundamental ...

Harmonic mode-locking (HML) is an advanced form of mode-locking process where multiple laser pulses are produced within one round trip of light. Mamyshev oscillators (MOs) employing HML are used for ...
