Many behavioural tasks require the manipulation of mathematical vectors, but, outside of computational models1–7, it is not known how brains perform vector operations. Here we show how the Drosophila central complex, a region implicated in goal-directed
Animals generate neural representations of their heading direction. Notably, in insects, heading direction is topographically represented by the activity of neurons in the central complex. Although head direction cells have been found in vertebrates, the
To decipher the genetic diversity within the cucurbit genus Citrullus, we generated telomere-to-telomere (T2T) assemblies of 27 distinct genotypes, encompassing all seven Citrullus species. This T2T super-pangenome has expanded the previously published r
CONSTITUTION:In a boundary memory 7, plural boundary coordinate corresponding to each boundary of azimuth display areas P1-P8 are normalized as points on the periphery and stored. Boundary vectors to these boundary coordinates are A1-A8. By the initialization, a vector product calculating circuit 61...
As well as pointing in the direction of the target object, this vector’s magnitude is equal to the distance between the two positions. It is common to need a normalized vector giving the direction to the target and also the distance to the target (say for directing a projectile). The ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Then, the basis vector pruning strategy is considered in the iteration to reduce computational cost by neglecting the impossible directions of signal presence. The converged speed of the joint estimation algorithm is further improved by approximately calculating the posterior probability density with the ...

This paper presents a millimeter-wave direction of arrival estimation (DoA) technique powered by dynamic aperture optimization. The frequency-diverse medium in this work is a lens-loaded oversized mmWave cavity that hosts quasi-random wave-chaotic radiat
