Long-sought Chicago police staffing study recommends adding more cops, hiring civilians

The study, conducted by Matrix Consulting Group, was commissioned by the City Council in February 2024 to find ways to close gaps between police response times in different neighborhoods.

Photonic integrated circuits enable programmable non-Abelian 'braiding' of light states

A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of ...

Exploring the Design Space of Distributed Parallel Sparse Matrix-Multiple Vector Multiplication

Abstract: We consider the distributed memory parallel multiplication of a sparse matrix by a dense matrix (SpMM). The dense matrix is often a collection of dense vectors. Standard implementations will ...

A Spectrally Efficient MIMO System with Sparse Matrix Precoding

Abstract: This paper proposes a novel technique of sparse matrix based precoding at the transmitter of a Multiple Input Multiple Output (MIMO) system. Our proposal, which we have called SMP-MIMO ...
