Brown Bag Seminar
The brown bag seminar is a weekly meeting organized by and for graduate students. The goal of the brown bag is to encourage students to practice presenting their work by giving talks to each other in a casual setting.
Decoherence and Spectrum Broad Cast Structures
DateFriday, April 5, 2019 - 12:00pm
AbstractI will introduce Spectrum Broad Cast Structures, a tool used in understanding quantum to classical transition. I will then apply this tool to some canonical decoherence models.
An Interactive Workshop to Combat Impostor Syndrome
AbstractThe workshop will be moderated by Drs. Laura Hunter and Mika Galilee-Belfer from the Office for Diversity and Inclusive Excellence, and will be informative for all levels of career (students, faculty, and staff). We hope to discuss the impacts of impostor syndrome on an individual level as well as from a mentoring perspective. The workshop will be interactive! To further foster the discussion among department members, we will have a lunch discussion immediately following the workshop. All are invited to the lunch, even if you are not able to attend the workshop, but an RSVP to Ken Yamamoto is required. If you are only available for part of the time (for either the lunch or the workshop), feel free to come just for that part.
Proactively managing your career
DateFriday, April 19, 2019 - 12:00pm
AbstractRegardless of your post-graduation plans, there are a few actions you can take now to help better position yourself for future opportunities. In this talk, I will offer insights on choosing coursework, applying to internships, and building a competitive resume/CV that will help you prepare for the next steps in your career.
Simulating Oxygen Transport in Large Microvascular Networks
DateFriday, April 19, 2019 - 12:00pm
AbstractOxygen transport to tissue primarily occurs in the microvasculature, and is strongly dependent on the geometry and topology of microvascular networks. Measurement of flow and oxygen concentration within these networks can be incredibly difficult due to the complex topologies and small size of vessels. In this talk, we present a method for calculating oxygen distribution and key macroscopic parameters (e.g. perfusion, oxygen consumption, and extraction) using boundary conditions that account for the embedding of the simulated region within its surroundings.
Nest architecture influences the colony organization of ants
DateFriday, April 26, 2019 - 12:30pm
AbstractFor some organisms, a near sessile life history mandates a strategic placement of where they live. Environmental constraints can be solved with an organism’s ‘extended phenotype’, or traits that extend into the environment: for example, in social insects, the nest, built by the colony, protects the colony from the external environment. Ants can thus change their local environments to the benefit of colony survival. Much attention has been given how organisms shape their extended phenotypes (e.g. nest architecture), while largely ignoring how organisms interpret them. The ant Temnothorax rugatulus provides an ideal model system to investigate the effects of nest architecture on colony organization, thus providing insight into the interactions between nest environment and its occupant. We tested the hypotheses that (i) nest architecture affects worker and brood spatial distribution, in particular (ii) that nest architecture would determine extent and distribution of spatial fidelity zones (‘micro-territories’) of workers in the nest, and that (iii) nest architectures promote different worker movement patterns. We use space syntax theory (structural accessibility) from human architectural research to determine the influence of spatial properties of the nest on the colony organization. Besides investigating the feedback between nest architecture and colony organization, our results may provide implications of nest accessibility on the behavior of the colony.
