Regularity of solutions for a fourth-order elliptic system via Conservation law

In this paper, we obtain interior Holder continuity for solutions of the fourth-order elliptic system Delta(2)u = Delta(V center dot del u) + div(w del u) + W center dot del u formulated by Lamm and Riviere [Comm. Partial Differential Equations 33 (2008) 2 ...

Unified theory of thermal transport in crystals and glasses

Nicola Marzari, Michele Simoncelli

Crystals and glasses exhibit fundamentally different heat conduction mechanisms: the periodicity of crystals allows for the excitation of propagating vibrational waves that carry heat, as first discussed by Peierls, while in glasses the lack of periodicity ...

Spatiotemporal dynamics of snow erosion, deposition and horizontal mass flux

Michael Lehning, Enrico Paterna, Philip Crivelli

The quantification of snow transport, both in wind tunnels and the field, apply particle counting methods limited to punctual sampling of relatively small volumes. Particle counting can only capture horizontal mass fluxes, failing to measure snow erosion o ...

Characterization and Modeling of 28 nm Bulk CMOS Technology down to Cryogenic Temperatures (4.2 K)

Christian Enz, Farzan Jazaeri, Arnout Lodewijk M Beckers

This paper presents an experimental investigation, compact modeling, and low-temperature physics-based modeling of a commercial 28-nm bulk CMOS technology operating at cryogenic temperatures. The physical and technological parameters are extracted at 300, ...

A dynamically forced cholera model for operational forecasting in Haiti

Waterborne diseases are among the leading causes of deaths in developing countries. The prompt intervention during an outbreak is crucial to limit the spread of an epidemic and reduce the number of casualties. The epidemiological models developed in the pa ...

On the Lagrangian structure of transport equations: The Vlasov–Poisson system

Maria Colombo

The Vlasov-Poisson system is an important nonlinear transport equation, used to describe the evolution of particles under their self-consistent electric or gravitational field. The existence of classical solutions is limited to dimensions d

Implementation of drift velocities and currents in SOLEDGE2D-EIRENE

Davide Galassi, Nicolas Mellet, Eric Serre

In order to improve cross-field transport description, drifts and currents have been implemented in SOLEDGE2D-EIRENE. The derivation of an equation for the electric potential is recalled. The resolution of current equation is tested in a simple slab case. ...

Numerical optimization of the ramp-down phase with the RAPTOR code

Olivier Sauter, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Anna Teplukhina

The ramp-down optimization goal in this work is defined as the fastest possible decrease of a plasma current while avoiding any disruptions caused by reaching physical or technical limits. Numerical simulations and preliminary experiments on TCV and AUG ha ...

On Decoupling Chemical Reaction Systems

Sriniketh Srinivasan

Chemical reaction systems act as the basis to get the desired products from raw materials. An in-depth understanding of all the underlying rate processes is necessary for monitoring, control and optimization of chemical reaction systems. Traditional repres ...

Characterization of the bottom turbid layer in a pit lake and its response to convective cooling

Tomy Doda

Base Mine Lake (BML) is a pit lake used to store the Fluid Fine Tailings (FFT) generated by the oil sands industry, in the Athabasca region (northern Alberta, Canada). It is well studied to try understanding its evolution over time and to determine if an e ...
