Vector analog computing via on-demand metasurface dispersive polarization transformation.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Optical analog computing can potentially feature high-throughput parallel processing with ultralow power and high speed and is promising for efficient signal processing. Previous platforms have mainly focused on scalar computing with optical intensities, which is highly sensitive to environmental disturbance and has been primarily restricted to single or basic computations because of intrinsic fixed correlation between the input and output signals. To our knowledge, for the first time, we use polarization vectors for optical analog computing with a single-layered metasurface to overcome these restrictions. The underlying mechanism is on-demand polarization transformation on the dispersive Poincaré spheres, constructing intrinsic variable correlations between the incident polarization vectors and output signals. We choose the universal logical gates and mathematical function operations as two specific examples. Experimental results of our vector computing metadevices exhibit minimal errors relative to the target values. Our work opens up an avenue for advanced optical signal processing across both classical and quantum domains.
