The Future of Economic Convergence [Audio]
Speaker(s): Professor Dani Rodrik | Emerging and developing economies have grown much more rapidly than rich countries recently. This has led to hopes that these countries can close the gap with the advanced economies and propel world growth. Historically, rapid convergence on the part of lagging countries has been rare and episodic, and has required a "benevolent" global hegemon which regards "unorthodox" catch-up policies with benign neglect. On top, growth requires structural transformation p

Denise Johnson, LGO '97, on the value of LGO to industry partners
MIT Leaders for Global Operations program graduate Denise Johnson ’97, General Manager for Specialty Products at LGO partner Caterpillar, speaks about the value to industry partners of participation in LGO. LGO is MIT’s dual-degree MBA and Engineering Master’s graduate program, unique in being supported by and informed by its close links with 24 partner companies. Previously an executive at another LGO partner, General Motors (most recently as President of GM Brazil), Johnson has an excell
Part Six: GAMBIT Summer Summit 2011
PART SIX: Every summer at the Singapore-MIT GAMBIT Game Lab, students from Singapore and the US work with GAMBIT researchers and development teams on novel game concepts, and visiting researchers spend that time research gaming related topics across a variety of fields. Back on July 6th, 2011, we drew back the curtains in the middle of the summer to provide insights into our current game development and research activities during the inaugural GAMBIT Summer Summit.

Is the End Near for the Eurozone?
Warning signs are flashing red. Bond markets are projecting a 98% chance of default on Greece's debt. Stock prices for French banks, heavily invested in that debt, have plunged 10% in recent days. Has the European debt crisis hit the breaking point, with Greece -- and perhaps others -- soon to exit the eurozone? Or, will officials once more cobble together new agreements that keep Greece in the club and prevent a huge contagion effect likely to cripple an already slowing global economy? Wharton
Stress-induced phase transformations in shape-memory polycrystals
Shape-memory alloys undergo a solid-to-solid phase transformation involving a change of crystal structure. We examine model problems in the scalar setting motivated by the situation when this transformation is induced by the application of stress in a polycrystalline material made of numerous grains of the same crystalline solid with varying orientations. We show that the onset of transformation in a granular polycrystal with homogeneous elasticity is in fact predicted accurately by the so-call
Characterization of soft stripe-domain deformations in SmC and SmC* liquid-crystal elastomers
The neo-classical model of SmC (and SmC*) elastomers developed byWarner and Adams predicts a class of ÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂ
A sharp interface model for the propagation of martensitic phase boundaries
A model for the quasistatic evolution of martensitic phase boundaries is presented. The model is essentially the gradient flow of an energy that can contains elastic energy due to the underlying change in crystal structure in the course of the phase transformation and surface energy penalizing the area of the phase boundary. This leads to a free boundary problem with a nonlocal velocity that arises from the coupling to the elasticity equation. We show existence of solutions under a technical c
A coarse-grained model of the myofibril: overall dynamics and the evolution of sarcomere non-uniform
A theoretical framework for predicting the macroscopic behavior of a muscle myofibril based on the collective behavior of sarcomeres is presented. The analysis is accomplished by rigorously transforming the nonlinear dynamics of an assemblage of sarcomeres into a partial differential equation for the probability distribution function of sarcomere lengths in the presence of stochastic temporal fluctuations and biological variability. This enables the study of biologically relevant specimens with
Spectral-element modeling of spontaneous earthquake rupture on rate and state faults: Effect of velo
We develop a spectral-element methodology (SEM) for simulating dynamic rupture on rate and state faults and use it to study how the rupture is affected by a shallow fault region of steady-state velocity-strengthening friction. Our comparison of the developed SEM and a spectral boundary-integral method (BIM) for an anti-plane (two-dimensional) test problem shows that the two methods produce virtually identical solutions for the finest resolution we use and that the convergence with grid reductio
Highly Nonlinear Solitary Waves in Periodic Dimer Granular Chains
We report the propagation of highly nonlinear solitary waves in heterogeneous, periodic granular media using experiments, numerical simulations, and theoretical analysis. We examine periodic arrangements of particles in experiments in which stiffer/heavier beads (stainless steel) are alternated with softer/lighter ones (polytetrafluoroethylene beads). We find excellent agreement between experiments and numerics in a model with Hertzian interactions between adjacent beads, which in turn agrees ve
Solutions to the Eshelby Conjectures
We present solutions to the Eshelby conjectures based on a variational inequality. We first discuss the meanings of the original Eshelby's statement. By Fourier analysis, we establish the connection between the homogeneous Eshelby inclusion problem and the classic Newtonian potential problem. We then proceed to the solutions of the Eshelby conjectures. Under some hypothesis on the material properties and restricted to connected inclusions with Lipschitz boundary, we show that one version of the
