A gluing operator for the ambitwistor string

Abstract We present a new operator in the ambitwistor string which glues together correlators with fewer points or Sunglasses of lower genus.It underpins the recursive construction of tree-level CHY scattering amplitudes by Dolan & Goddard, as well as the computation of loop integrands on a Riemann sphere by Geyer et al.The gluing operator is a tra

Facial Affect Recognition Training Through Telepractice: Two Case Studies of Individuals with Chronic Traumatic Brain Injury

The use of a modified Facial Affect Recognition (FAR) training to identify emotions was investigated with two case studies of adults with moderate to severe chronic (> five years) traumatic brain injury (TBI).The modified 5-16 C FAR training was administered via telepractice to target social communication skills.Therapy consisted of identifying
