Loss of presenilin 2 age-dependently alters susceptibility to acute seizures and kindling acquisition
Autor: Megan Beckman, Kevin Knox, Zachery Koneval, Carole Smith, Suman Jayadev, Melissa Barker-Haliski
Publikováno v: Neurobiology of Disease, Vol 136, Iss , Pp 104719- (2020)
Patients with Alzheimer's disease (AD) experience seizures at higher rates than the general population of that age, suggesting an underexplored role of hyperexcitability in AD. Genetic variants in presenilin (PSEN) 1 and 2 genes lead to autosomal dom

Exploring the Influence of an Interprofessional Student-Run Clinic on Matriculation to Health Professional School: A Retrospective Cross-Sectional Study
Autor: Erik Vanstrum, Sukriti Mohan, Janis Yue, Daniella Veloria, Justin Quon, Renee Lee, Kevin Knox, Cha Chi Fung
Publikováno v: Journal of Student-Run Clinics. 8
Background: Projected demographic trends in the United States suggest increasing racial and ethnic diversity. It is important that the healthcare workforce reflects these trends to reduce healthcare disparities among underserved populations. For exam

Trapping surface electrons on graphene layers and islands
Autor: Marko Kralj, Jerry I. Dadap, Po-Chun Yeh, Kevin Knox, Nader Zaki, Th. Fauster, Marin Petrović, Daniel Niesner, Rohan Bhandari, Richard M. Osgood
Publikováno v: Physical Review B. 85
We report the use of time- and angle-resolved two-photon photoemission to map the bound, unoccupied electronic structure of the weakly coupled graphene/Ir(111) system. The energy, dis- persion, and lifetime of the lowest three image-potential states

Observation of Image States in Graphene on Ir(111) by Two-Photon Photoemission
Autor: Rohan Bhandari, Richard M. Osgood, Nader Zaki, Marin Petrović, Marko Kralj, Jerry I. Dadap, Kevin Knox, Po-Chun Yeh
We report observation of image states of graphene on Ir(111) using two-photon photoemission (2PPE). We also investigate the 2PPE dependence on graphene coverage, photon energy, and electron scattering angle to study the graphene-substrate interaction

Free-standing exfoliated monolayer graphene is an ultrathin flexible membrane, which exhibits out-of-plane deformation or corrugation. In this paper, a technique is described to measure the band structure of such free-standing graphene by angle-resol

Two-Photon Photoemission Can Map Femtosecond-Lived Unoccupied Bulk States
Autor: Mehmet Yilmaz, P. D. Johnson, Richard M. Osgood, Kevin Knox, Jerry I. Dadap, Nader Zaki, Zhaofeng Hao
Publikováno v: Conference on Lasers and Electro-Optics 2010.
We use a tunable 100-fs UV source to demonstrate angle-resolved two-photon photoemission band mapping of bound but unoccupied bulk bands, viz. Cu sp-band. The strong optical pumping overcomes the femtosecond lifetime of this bulk feature.

Low-energy electron microscopy and microprobe diffraction are used to image and characterize corrugation in SiO(2)-supported and suspended exfoliated graphene at nanometer length scales. Diffraction line-shape analysis reveals quantitative difference
