Hostility and Cardiovascular Regulation: An Investigation of Lateralized Pre-Motor Functions
… right frontal deficits in lateral eye movements (LEM) resulting in decreased LEM toward and within the left hemispace. Moreover, concurrent processing of lateralized eye movements and regulation over cardiovascular responding was predicted to yield sympathetic dysregulation on leftward LEM (lLEM) …

Elastic properties and failure behavior of disordered porous solids : a potential-of-mean-force-based lattice element approach
… end, a discrete simulation tool -coined lattice element method (LEM)- was implemented. Akin to potential-of-mean-force approaches used in soft-matter physics, a solid structure is discretized into mass points interacting with the nearest neighbors through effective interaction potentials. …
