UN announces new Expert Advisory Panel to advance efforts in quantifying countries’ multidimensional vulnerabilities

United Nations Secretary-General António Guterres has appointed 15 leading experts to the Independent Expert Advisory Panel for the Multidimensional Vulnerability Index (MVI) for the 2026–2030 term.

Neutral-atom arrays, a rapidly emerging quantum computing platform, get a boost from researchers

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

Crámer-Rao Bound Analysis for Mixed-ADC Direction of Arrival Estimation in Two-Dimensional Arrays

Abstract: Digital modulation schemes, such as phase-modulated continuous wave (PMCW) and orthogonal frequency-division multiplexing (OFDM), require high-sampling analog to-digital converters (ADCs), ...

Two-dimensional Close-packed Arrays of Polystyrene Microspheres Bragg Grating for Refractive Index Sensing

Abstract: For fiber Bragg grating (FBG) with a one-dimensional (1D) photonic crystal structure based on silica materials, its photonic bandgap can only respond to temperature and strain. We combined ...
