Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance
, 2007
"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

. Benchmark Determinants of Fund Performance We begin by replicating Kaplan and Schoar's (2005) fund performance model, to validate our use of exit rates instead of fund returns as the measure of performance. Kaplan and Schoar relate VC fund performance to two fund characteristics (as well as a set
COSMOLOGICAL MODELS OF MODIFIED GRAVITY
, 2013
"... The recent discovery of dark energy has prompted an investigation of ways in which the accelerated expansion of the universe can be realized. In this dissertation, we present two separate projects related to dark energy. The first project analyzes a class of braneworld models in which multiple brane ..."

-energy description can be obtained for braneworld scenarios, allowing for a number of generalizations to the original models. This method is applied to orbifolded and uncompactified N-brane models, deriving an effective four-dimensional action. The parameter space of this theory is constrained using observational
The Asymptotics of Selecting the Shortest of Two, Improved
"... Abstract We investigate variations of a novel, recently proposed load balancing scheme based on small amounts of choice. The static (hashing) setting is modeled as a balls-and-bins process. The balls are sequentially placed into bins, with each ball selecting d bins randomly and going to the bin wit ..."

ties in a fixed, asymmetric fashion, actually improves performance, whereas in all previous analyses, ties were broken randomly. We demonstrate the nature of this improvement using fluid limit models, suggest further improvements, and verify and quantify the improvement through simulations.
i A TRANSIENT COMPUTATIONAL FLUID DYNAMIC STUDY OF A LABORATORY-SCALE FLUORINE
"... Fluorine gas is produced industrially by electrolysing hydrogen fluoride in a potassium acid fluoride electrolyte. Fluorine is produced at the carbon anode, while hydrogen is produced at the mild-steel cathode. The fluorine produced has a wide range of uses, most notably in the nuclear industry wher ..."

Integrating Shape and Texture in 3D Deformable Models: From Metamorphs to Active Volume Models
"... Abstract For the purpose of object boundary extraction, traditional shape-based deformable models rely on external image forces that come primarily from edge or image gradient information. Such reliance on local edge information makes the models prone to get stuck in local minima due to image noise ..."

and not sensitive to noise and spurious edges inside the object of interest. Then, we review Active Volume Model (AVM), a similar and improved approach for 3D segmentation. The shape of this 3D model is considered as an elastic solid, with a simplex-mesh surface made of thousands of vertices. Deformations
Abstract Multichannel Communication in Contiki's Low-power IPv6 Stack
"... Vast majority of wireless appliances used in household, industry and medical field share the ISM frequency band. These devices need to coexist and thus are challenged to tolerate their mutual interference. One way of dealing with this is by using frequency hopping; where the device changes its radio ..."

We illustrate two flavors of the protocol; one that does not use any dedicated channel and another which allows dedicated
