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

Recent advances in neuromorphic resistive switching have enabled us to start emulating biological synapses and neurons. A liquid switching medium brings these devices even closer to brain-like systems, being soft and flexible. Here, we propose copper solution-based artificial synapses that show both nonvolatile and volatile, and excitatory and inhibitory behavior, without an electroforming step. Different copper sulfate solutions, concentrations, electrode materials, and spacings were studied. Low operation voltage was achieved for the aqueous solution, showing high endurance and data retention. By changing solvation to glyceline, a change between nonvolatile and volatile dynamics occurred, while maintaining neuromorphic behavior and enhancing stability. This shows, for the first time, both potentiation and depression in a volatile device. Our results are promising for bio-voltage neuromorphic memristor-based interfaces.
