The first actively managed exchange-traded fund share classes are one step closer to becoming a reality. Dimensional submitted its first request for ETF share classes on Thursday, Oct. 9, 2025. The ...
Abstract: We propose and simulate a two-dimensional optical phased array using a silicon-based optical integrated circuit. Beam steering is achieved over a range of 11.73° × 11.9° at a fixed ...
Fixed-Dimensional Encoding (FDE) solves a fundamental problem in modern search systems: how to efficiently search through billions of documents when each document is represented by hundreds of vectors ...
Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...
As we move, engage and click our way through the world, we often change the “hat” we wear multiple times in the span of a single day. Part strategist, part musician, part fan, I might flex between ...
In a groundbreaking experiment, researchers from Tsinghua University have proven that two-dimensional (2D) semiconductor materials can withstand the harsh conditions of space. The team, led by ...
In April 1982, Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 Nobel Prize in Chemistry: the quasiperiodic crystal. According ...
Abstract: Two-dimensional (2-D) array sets with good 2-D correlation properties have received considerable attention in wireless communication systems. This paper focuses on 2-D Z-complementary array ...
