We present here a first step towards developing a quantitative model that relates investor emotions to financial markets. We used Wall Street Journal articles as a proxy of investor emotions on a "macro" level. We measured the emotional characteristic of…

DSpace is a joint development project of the Massachusetts Institute of Technology Libraries and Hewlett-Packard Company. Its mission is to establish a library service to capture, distribute, and preserve the digital, intellectual output of the MIT community. We are developing…

Thin wires are attached on the outer surface and parallel to the axis of a smooth
circular cylinder in a steady cross-stream, modelling the effect of protrusions and
attachments. The impact of the wires on wake properties, and vortex-induced loads

This thesis traces the development of American bacteriology during the first quarter of the twentieth century. While bacteriology experienced a period of rapid growth, an enduring disciplinary anxiety equally characterized the field. In particular, bacteriologists feared increasing specialization and conceptual…

We have derived a broad, deterministic model of the steady-state actin cycle that includes its major regulatory
mechanisms. Ours is the first model to solve the complete nucleotide profile within filaments, a feature that determines the
dynamics and geometry of…

Significant progress has been made in understanding
some of the basic mechanisms of force production and flow manipulation
in oscillating foils for underwater use. Biomimetic observations,
however, show that there is a lot more to be learned, since
many of…

We describe the general phenomenon of ‘induced-charge electro-osmosis’ (ICEO) –
the nonlinear electro-osmotic slip that occurs when an applied field acts on the ionic
charge it induces around a polarizable surface. Motivated by a simple physical picture,
we calculate ICEO…

The design and construction of a biomimetic flapping
foil autonomous underwater vehicle is detailed. The vehicle was
designed as a proof of concept for the use of oscillating foils as
the sole source of motive power for a cruising and…
