[Illinois] Beckman Director's Seminar - Quantitative Phase Imaging
Online Presentations | 26 Nov 2012 | Contributor(s): Gabriel Popescu | 38 users
"Ever since the invention of the microscope in the 17th century, it has been observed that live cells are transparent under visible illumination, i.e. they do not absorb (or scatter) light significantly. Thus, a magnified image of cells will generally exhibit low contrast. In order to overcome...

[Illinois] Beckman Graduate Seminar: Dispersion-relation Spectroscopy of Intracellular Transport
Online Presentations | 18 Dec 2012 | Contributor(s): Ru Wang | 44 users
The interior of a living cell is a busy place. Molecular motors move materials along prescribed biopolymer tracks. This sort of active transport is required to rapidly move products over large distances within the cell, where passive diffusion is too slow. Just as understanding the flow of...

[Illinois] Beckman Graduate Seminar: Membrane Sculpting by F-BAR Domains Studied by Molecular Dynamics Simulations
Online Presentations | 18 Dec 2012 | Contributor(s): Hang Yu | 29 users
Interplay between cellular membranes and their peripheral proteins drives many processes in eukaryotic cells. Proteins of the Bin/Amphiphysin/Rvs (BAR) domain family, in particular, play a role in cellular morphogenesis, for example curving planar membranes into tubular membranes. However, it is...

[Illinois] Beckman Graduate Seminar: What can listeners learn about different speakers' voices?
Online Presentations | 01 Feb 2013 | Contributor(s): Alison M. Trude | 20 users
The research in learning extends from studies of the very young to fully mature adults. How do we learn about the world and how to act in it? Research in advanced knowledge acquisition is directed toward instructional strategies that allow people to master complex concepts, such as mathematical...

[Illinois] Beckman Graduate Seminar: Quantitative Phase Imaging for live cell studies
Online Presentations | 01 Feb 2013 | Contributor(s): Mustafa Mir | 29 users
Faculty members in the Bioimaging Science and Technology group develop new imaging technologies for medical diagnosis and treatment, as well as new methods for discovering the ways our bodies work. Because of the extensive imaging facilities at the Beckman Institute, we are able to explore very...

[Illinois] Beckman Graduate Seminar: Neural Correlates of Externally and Internally Originating Emotional Distraction Effects on Working Memory
Online Presentations | 20 Jun 2013 | Contributor(s): Alexandru D. Iordan | 24 users
Balanced emotion-cognition interactions are critical for healthy functioning. Clinical studies suggest that symptoms of impaired executive control and enhanced emotional distractibility observed in affective disorders are linked to dysfunctional interactions between a dorsal executive system and...

[Illinois] Beckman Graduate Seminar: Frontoparietal traffic signals: A fast optical imaging study of preparatory dynamics in response mode switching
Online Presentations | 20 Jun 2013 | Contributor(s): Pauline L. Baniqued | 36 users
Coordination between networks of brain regions is important for optimal cognitive performance, especially in attention demanding tasks. With the event-related optical signal (EROS; a measure of changes in optical scattering due to neuronal activity) we can characterize rapidly evolving network...

[Illinois] Beckman Graduate Seminar: Graphene Atomic Shrink Wrap for Nanosandwiching Biomolecules
Online Presentations | 20 Jun 2013 | Contributor(s): Joshua D. Wood | 28 users
Graphene, a two-dimensional honeycomb sheet of carbon atoms, has been hotly scrutinized for its desirable electronic applications. Still, graphene has hardly been used as an atomically thin membrane. Graphene membranes are conformal to surfaces, entrapping liquids, gases, and nanoparticles. Here,...
