Cut-Enabled Mechanical Metamaterials for Multimodal and Reprogrammable Static Nonreciprocity.
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 3 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
Static nonreciprocity offers distinct outputs when switching the positions of action and reaction, which is of great interest for designing mechanical logic elements or soft robots. Existing mechanical metamaterials can present specific static nonreciprocal responses, but it remains challenging to obtain multiple and reprogrammable static nonreciprocal modes in a single microstructural topology. Here, a design method of cellular metamaterials is demonstrated via leaving cuts inside metacells, whose contact nonlinearity in the single metacell can offer orthogonal, uniaxial, shear (displacement and Poynting effect) static nonreciprocal modes. A framework using constitutive tensors is established to describe the multi-modal nonreciprocal behaviors. Moreover, the static nonreciprocal responses of the metamaterial array are programmable via encoding (retaining or constraining) the positions of cuts. This work offers a pathway to synthesize multiple nonreciprocal modes and control the nonreciprocal responses, enhancing the functionality of metamaterials.
