Active vision dynamically refines spatiotemporal neural representations, optimising visual processing through scanning behaviour and non-associative learning, providing insights into efficient sensory ...

Cosmic mystery deepens as astronomers find object flashing in both radio waves and X-rays. International Centre for Radio Astronomy Research. Journal Nature DOI 10.1038/s41586-025-09077-w- ...

First I generate descriptors using asap gen_desc -f train.xyz soap Then I tried to plot PCA map using asap map -f ASAP-desc.xyz -dm '[SOAP*]' -c energy pca . But it raise an error: ValueError: ...

The signal appears as a low-frequency rumble, common to all pulsars in the array. As the gravitational waves wash over Earth, they affect the apparent rotation rates of the pulsars.

Two OpenJDK draft proposals would enhance the expressiveness of pattern matching in Java and boost data-oriented queries, potentially previewing in Java 17.

Part 1 of the series covered beam direction and working with a uniformly spaced linear array of antennas. In part 2, we’ll cover antenna gain, directivity, and aperture, as well as array factors.

where D is the diameter of the antenna ((N-1) × d for our uniform linear array).. For a small array (small D) or a low frequency (large λ), the far-field distance is small.But for a large array (or ...
