Sac State Physics Majors' Senior Project Talks
Peter Helldorfer
"
Development Process of a Low Cost High Accuracy Three-Axis Magnetometer Unit for Sensing Earth's Magnetic Field by Averaging Output of Several Magnetometer Microchips"

This talk will outline the process to build and implement a custom printed circuit board utilizing the Tiva TM4C1294NCPDT Microcontroller by Texas Instruments and the MAG3110 Magnetometer by NXP Semiconductors as a low cost middle-of-the-road magnetometer unit. Professionally manufactured high accuracy magnetometer units can be prohibitively expensive, on the order of thousands of dollars, while cheaper units may be unable to provide an acceptable level of accuracy. This unit is intended to fill this gap at a cost of about one hundred dollars per unit.

"Modeling of Tropomyosin Binding and Polymerization on Filamentous Actin"

Actin and tropomyosin are cytoskeletal proteins that play a role in the functions of muscle tissue. Tropomyosin spans 7 binding sites on F-actin, raising the possibility of gaps of 1-6 binding sites between tropomyosins bound “out of register”. Gaps in tropomyosin decoration on actin would have significant functional impact in both muscle and non-muscle cells, but it is still unclear if gaps are ever present biologically, or how they resolve themselves. Here I simulate computationally tropomyosin binding to filamentous actin, and investigate how lateral diffusion of tropomyosin on actin could serve to eliminate gaps.

The Physics and Astronomy Colloquium Series is open to all members of the university. Unless otherwise noted, talks are held on Thursday afternoons at 4:00-5:20 in Mendocino 1015. Schedule is regularly updated as dates, titles, and abstracts are received. Please check back often. To receive updates about the Colloquium Series, please join our Events Mailing List. For past semesters' series, see our archive.
