The valuation criterion for normal basis generators

If L/K is a finite Galois extension of local fields, then we say that the valuation criterion VC(L/K) holds if there is an integer d such that every element x is an element of L with valuation d generates a normal basis for L/K. Answering a question of Byo ...

Institutional Investors and Mutual Fund Governance: Evidence from Retail-Institutional Fund Twins

Rüdiger Fahlenbrach

Advisors often manage multiple versions of a fund. These "twins" have the same manager and similar performance but are sold to different investors with differing abilities to select and monitor managers. Comparing investor flows in retail and institutional ...

Incomplete information, idiosyncratic volatility and stock returns

Julien Hugonnier, Tony Berrada

When investors have incomplete information, expected returns, as measured by an econometrician, deviate from those predicted by standard asset pricing models by including a term that is the product of the stock's idiosyncratic volatility and the investors' ...

Optimal open-loop control of the recirculation length in the wake of a cylinder

François Gallaire, Edouard Boujo

We consider steady equilibrium solution of the 2-D Navier-Stokes equations describing the flow around a circular cylinder. It is well known that, for moderate Reynolds numbers, the recirculation length is an increasing function of the Reynolds number. We f ...

Separate encoding of model-based and model-free valuations in the human brain

Behavioral studies have long shown that humans solve problems in two ways, one intuitive and fast (System 1, model-free), and the other reflective and slow (System 2, model-based). The neurobiological basis of dual process problem solving remains unknown d ...

Propagation Models for Biochemical Reaction Networks

Maria-Emanuela-Canini Mateescu

In this thesis we investigate different ways of approximating the solution of the chemical master equation (CME). The CME is a system of differential equations that models the stochastic transient behaviour of biochemical reaction networks. It does so by d ...

A mean field approach for optimization in discrete time

Nicolas Gabriel Gast

This paper investigates the limit behavior of Markov decision processes made of independent objects evolving in a common environment, when the number of objects (N) goes to infinity. In the finite horizon case, we show that when the number of objects becom ...

Non-invasive calibration technique of a 2D hydrodynamic model based on pattern recognition and digital mapping

Paolo Perona

Hydrodynamic models are important tools in civil and environmental engineering. When properly calibrated, numerical flow simulations are helpful to study the impact of floods as natural hazards for the built environment, or as inundation dynamics connectin ...

Secondary Currents and Corresponding Surface Velocity Patterns in a Turbulent Open-Channel Flow over a Rough Bed

Ulrich Lemmin, Ismail Albayrak

River and open-channel flows present complex three-dimensional (3D) structures in the water column and on the surface as a result of the existence of secondary currents driven by either centrifugal force or turbulence. This paper experimentally investigate ...

Interaction of large scale flow structures with gyrokinetic turbulence

Laurent Villard, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

Shear flows have a profound influence on turbulence-driven transport in tokamaks. The introduction of arbitrary initial flow profiles into the code ORB5 [Jolliet et al., Comput. Phys. Commun. 177, 409 (2007)] allows the convenient study of how flows on all ...
