We formulate the problem as a signal-to-interference-plus-noise ratio maximization, by jointly optimizing the receive beamforming and antenna element positioning. Due to the non-convexity and ...

This work demonstrates a novel approach to advance multi-beam radiation patterns in indoor optical wireless networks by utilizing a cluster-based optical aperture comprising IR radiative elements ...

Then, they used principal component analysis (PCA) to study the effects of these characteristics on the dispersity of milk powder, and found that roundness, convexity and area ... breakdown spectra to ...

It is a subtle means of uniting those two hardly compatible elements in the building ... Its shape suggests a tent, and this tent-like character, ie, its convexity, is suggested by acoustics: the ...

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the transuranium element berkelium. According to a new study, the electronic signature of ...

A Northwestern University-led international team of scientists has, for the first time, directly observed catalysis in-action ...

A study from Technion unveils a newly discovered form of quantum entanglement in the total angular momentum of photons ...

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the Sun. A Southwest Research Institute-led team of scientists sought the source ...

Day 3 in Sri Lanka: PM Modi gets guard of honour from SL air force, launches India-backed project with 'friend' Anura Kumara Dissanayake 'Stop thebillionairecoup': Americans fill streets, hold ...
