The translocation of biopolymers such as DNA through nanopores has received a great deal of attention due to applications such as sequencing DNA or sorting polymers by size. In this presentation I will discuss results from a joint experimental-theoretical project examining the translocation of the filamentous fd virus through nanopores. The fd virus is relatively stiff with a persistence...

Recent advancements in nanotechnology have attracted worldwide attention. The potential applications of metallic nanoparticles, especially gold nanoparticles or nanorods (or gold colloids), are very promising and attractive. The unique optical, chemical, and physical properties of gold nanoparticles make them an ideal candidate for biochemical sensing, medical diagnostics/therapeutics, imaging...

Invited Speaker / Conférencier invité
This talk will discuss a non-conventional neural coding task that may apply more broadly to many senses in higher vertebrates. We ask whether and how a non-visual sensory system can focus on an object. We present recent experimental and modeling work that shows how the electric sense can perform such neuronal focussing. This sense is the main one used by weakly electric fish to navigate,...

In the murky waters of the tropics, live weakly electric fish which use a continuous high frequency electric organ discharge (EOD) to sense nearby objects and communicate with conspecifics. Eigenmannia’s characteristic frequency is within the species range of 250 to 600 Hz which it shifts when necessary to avoid jamming. The nearly dipolar oscillating electric field is generated by parallel...

The vertebrate ear both responds to and emits sound. Sounds from the ear, known as otoacoustic emissions (OAEs), provide a means to probe the biophysics of auditory transduction and amplification. Spontaneous emissions (SOAEs) can also be present, appearing as coherent peaks in the spectral domain. Statistical properties of SOAEs, such as the “ring of fire” (observed via a 2-D histogram of the...
