1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Ultrafast dynamic vision remains a major challenge for autonomous systems like drones, particularly considering their strict power and computational constraints. Here, we present an artificial spherical compound eye (ASCE) that enables nanosecond-scale, event-driven motion detection across a panoramic field of view (294°). Each pixel is self-powered and responds exclusively to dynamic light changes, enabling real-time sensing with minimal processing. An 8 ns response time is achieved under femtosecond laser excitation, alongside exceptional stability exceeding 10⁸ switching cycles. In addition, the ASCE features a simple structure with in situ grown nanowires and dielectric layer. The one-step fabrication process allows for conformal pixel integration on spherical and other three-dimensional surfaces. We demonstrate its versatility across multi-scale applications, including drone-based laser alarming and real-time motion tracking. These results establish ASCE as a promising platform for energy-efficient, high-speed vision in autonomous robotics and intelligent surveillance.
