Surface Groups are Frequently Faithful

We show the set of faithful representations of a closed orientable hyperbolic surface group is dense in both irreducible components of the PSL2(K) representation variety, where K = C or R, answering a question of W. Goldman. We also prove the existence of faithful representations into PU(2, 1) with certain nonintegral Toledo invariants.

Triggered EMG Potentials in Determining Neuroanatomical Safe Zone for Transpsoas Lumbar Approach: Are They Reliable?

STUDY DESIGN In vivo analysis in swine model. OBJECTIVE The purpose of this study was to determine the accuracy of triggered EMG (t-EMG) and its reliability in lateral lumbar interbody fusions surgery. We also aim to document changes in psoas muscle produced during the approach. SUMMARY OF BACKGROUND DATA Lateral lumbar interbody fusions is preferred over direct anterior approach because of...

Are we really in safe hands? How safe is safe?

[Handicapped children are frequently victims of violence].

Estimations of object frequency are frequently overestimated.

Real-world scenes are complex but lawful: blenders are more likely to be found in kitchens than beaches, and elephants are not generally found inside homes. Research over the past 40years has demonstrated that contextual associations influence object recognition, change eye movement distributions, and modulate brain activity. However, the majority of these studies choose object-scene pairs from...
