Acoustic Metasurface for Space-time Reflection Manipulation.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Recently, space-time modulation has revolutionized the wave engineering technologies, providing unprecedented opportunities beyond traditional static systems. This advancement is crucial across diverse fields, ranging from non-reciprocal transmission to wireless communication. However, the current approaches to sound modulation require bulky artificial structures and are limited in achieving space-time-variable sound-matter interactions. Here, a prototype of space-time acoustic metasurface (STAM) is proposed and implemented, consisting of a reflective piezoelectric array controlled by a field-programmable gate array. Leveraging the spatiotemporally programmable phases of the STAM, this is experimentally achieved Doppler-like chirp modulation and space-time modulation with deterministic frequency and momentum shifts of waterborne acoustic waves. Furthermore, based on this flexible and efficient modulation strategy, a stochastic space-time modulation method is introduced, showcasing its applications in single-channel direction-of-arrival estimation. The proposed STAM extends the frontier of wave control and thereby lays the foundation for versatile space-time applications involving sound.
