Hace 3 días · Wavelength: Usually denoted λ, this is the distance along the wave between points of maximum stretch or squeeze. Speed: This is the speed at which a point on the wave (for example, a point of maximum stretch or squeeze) travels. For gravitational waves with small amplitudes, this wave speed is equal to the speed of light (c).
Hace 23 horas · The International Energy Agency predicts that artificial intelligence will consume 10 times as much power in 2026 as it did in 2023, and that data centers in that year will use as much energy as Japan. “The amount of [computing power] that AI needs doubles every three months,” said Nick Harris, founder and CEO of the computing-hardware ...
Hace 2 días · SUMMARY Redox changes of pyridine nucleotides in cellular compartments are highly dynamic and their equilibria are under the influence of various reducing and oxidizing reactions. To obtain spatiot...
Hace 23 horas · Effect of self-focusing of a \(q\)-Gaussian laser beam on higher harmonic generation in a preformed collisionless parabolic plasma channel has been investigated.The ponderomotive force due to non uniform intensity distribution of the laser beam redistributes carriers from high field region to low field region, resulting in a transverse density gradient in the channel.
