Solar flares strong enough to knock out satellites and buckle power grids are, by definition, rare. That rarity is exactly ...

Phase retrieval algorithms are known to be sensitive to the seed, i.e., the initial phase approximation at the antenna aperture. An example where this seed can be critical is while considering an ...

During the measurement, the kinetic energy spectrum of the photoelectrons is recorded as a function of the delay between two pulse replicas ionizing the gas target (see Fig. 1). The recorded ...

Ptychography is a computational imaging technique capable of reconstructing high-resolution phase and amplitude images from overlapping diffraction patterns. However, existing reconstruction ...

This repository implements an optical wavefront retrieval algorithm based on interferometric grating patch methods. It enables correction of SLM-induced and optical aberrations for high-fidelity phase ...

Google’s June 2025 Core Update just finished. What’s notable is that while some say it was a big update, it didn’t feel disruptive, indicating that the changes may have been more subtle than game ...

Google announced a new multi-vector retrieval algorithm called MUVERA that speeds up retrieval and ranking, and improves accuracy. The algorithm can be used for search, recommender systems (like ...

Figure 1： The flowchart of ACDPC iterative reconstruction joint optimization algorithm. (a) ACDPC imaging system based on half-annular illumination. (b) Three annular illumination patterns and their ...
