Using ab initio calculations, we discovered a quasi two-dimensional copper–bismuth nano sheet, which we call cubine. According to our predictions, single layers of cubine can be isolated from the recently reported high-pressure CuBi bulk material at an extremely low energetic cost, comparable to values to separate single layers of graphene...
Psychometric analyses can help illuminate how people approach clinical tests. To understand how health literacy (i.e., literacy for health information) might lead to biased assessment of emotional distress, we examined the psychometric properties of anxiety and depression questionnaires, using differential item functioning (DIF) analysis. Items were flagged for DIF if...
Our research group is currently working to develop the first cross-culturally validated household water insecurity scale. In order to do this, we have partnered with numerous collaborators to implement the survey in diverse ecological settings. As part of the survey, participants are asked to recall how long it takes to...
Mixing due to cutting-and-shuffling is studied at a fundamental level using 2D mappings known as Piecewise Isometries (PWI) which can create beautiful mixing patterns. The PWI studied here splits a hemispherical shell (HS) into four curved triangular pieces that are rearranged to make a shuffled HS. Applying the PWI repeatedly...
This visualization shows two-photon imaging of GCamp6f in hippocampal pyramidal neurons as a mouse navigates a virtual reality maze. These techniques give us an indirect measure of activity in neurons or small compartments of neurons in an awake, behaving animal. The hippocampus has been well characterized as playing an essential...
