Equivalent approaches to dealing with unobserved heterogeneity in cross-lagged panel models? Investigating the benefits and drawbacks of the latent curve model with structured residuals and the random intercept cross-lagged panel model.

Psychological Methods, 2020
Panel models in structural equation modeling that combine static and dynamic components for investigating reciprocal relations while controlling for time-invariant unobserved heterogeneity are becoming increasingly popular. Recently, the Latent Curve Model with Structured Residuals and the Random-Intercept Cross-Lagged Panel Model were suggested as ...

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
