Although critical to atmospheric modeling of stratospheric ozone depletion, selective heterogeneous nuclei that promote the formation of Type Ia polar stratospheric clouds (PSCs) are largely unknown.

In a realistic wireless environment, the multi-antenna channel usually exhibits spatially correlated fading. This is more emphasized when a large number of antennas is densely deployed, known as ...

In the atmospheric layer above it, about 10 to 30 miles up, is the stratospheric polar vortex, where every winter a sunlight-starved Arctic spins up a mass of cold air that, ultimately, dissipates ...

This paper presents SimMIM, a simple framework for masked image modeling. We have simplified recently proposed relevant approaches, without the need for special designs, such as block-wise masking and ...
