This course will be concerned with the analysis of thin elastic films which exhibit residual stress at free equilibria. Examples of such structures include, in particular, growing tissues such as leaves, flowers or marine invertebrates, as well as specifically engineered gels. There, it is conjectured that the growth process results in the forma...

Elastic materials exhibit qualitatively different responses to different kinematic boundary conditions or body forces. As a first step towards understanding the related evolutionary problem, one studies the minimizers of an appropriate nonlinear elastic energy functional.We shall give an overview of recent results, rigorously deriving 2d elastic...

In this talk we will discuss how the mechanical response of an elastic film is affected by subtle geometric properties of its mid-surface. The crucial role is played by spaces of weakly regular (Sobolev) isometries or infinitesimal isometries. These are the deformations of the mid-surface preserving its metric up to a certain prescribed order of...

Replica exchange (RE) is a generalized ensemble simulation method for accelerating the exploration of free-energy landscapes which define many challenging problems in computational biophysics, including protein folding and binding. Although replica exchange is a parallel simulation technique whose implementation is relatively straightforward, ki...

In this interview, Roberta Levy gives an account of her life as a Jewish Minnesotan and legal practitioner. She was born in 1937 in Philadelphia to Russian immigrant parents who were persecuted abroad. Recalling her early life, she describes how her father had a store in Philadelphia and was a committed Socialist/Zionist. She gives a description...

Thin liquid films are important in applications involving lubricationor coating, which arise in both biological and industrial contexts.Recent experiments have uncovered new phenomena that presentchallenges of modeling, analysis and simulation. These include newwave forms, fingering instabilities, and a variety of driving andcontrol mechanisms. ...

Nathan Levitt is a white trans man and family nurse practitioner based in New York City. At the time of this interview, he worked in the office of Dr. Rachel Bluebond-Langner, who specializes in gender-affirming surgeries. In the interview, Levitt discusses the evolution of practices in trans health care. Specifically he recounts his experiences...
Over the last three decades computer simulation have been able to bring atomic motion to structural biology. Such motion is not seen in experimental structural studies but is relatively easily studied by applying law of motions to models of the proteins and nucleic acids. By bringing molecular to life in this way, simulation complements experime...
