Nanoplatforms for Sentinel and Tumor‐Draining Lymph Node Mapping: From Visualization to Pathway‐Informed Staging

open access: yesAdvanced Healthcare Materials, EarlyView.
Lymphotropic nanoplatforms integrate multimodal imaging with therapeutic guidance to map sentinel and tumor‐draining lymph nodes, revealing functional drainage, metastatic involvement, and nodal accessibility, while providing mechanistic insight to support precision surgical and therapeutic interventions.

Putting motor resonance in perspective

Cognition, 2008
Perceiving another person's actions changes the spatial perspective people use to describe objects in a scene, possibly because seeing human action induces people to map the actions, including their spatial context, to their own body and motor representations [Lozano, S. C., Hard, B. M., & Tversky, B. (2007). Putting action in perspective.

Imitation in Infancy: Rational or Motor Resonance?

Child Development, 2011
Abstract The present study investigates the contribution of 2 mechanisms to imitation in infancy. The principle of rational action suggests that infants normatively evaluate the efficiency of observed actions. In contrast, it has been proposed that motor resonance (i.e., the mapping of others’ actions onto one’s own motor repertoire ...

Subharmonic resonance in stepping motors

Proceedings of the Institution of Electrical Engineers, 1979
A study of the resonance phenomena that can occur in stepping motors operating at pulse rates above the natural frequency is described. This resonant behaviour is distinct from the dynamic instability present at much higher stepping rates. In particular, a resonance oscillation is investigated which occurs when the pulse rate is twice the natural ...

Resonance effects in stepping motors

Proceedings of the Institution of Electrical Engineers, 1977
The mechanism of resonance-induced maloperation of stepping motors is studied, and a simple analytical method is presented enabling resonance frequency bands, and the damping factors necessary to suppress resonance, to be predicted. Emphasis is placed on the determination of the equivalent linearised torque/displacement characteristic for practical use.
