Parameter estimation problems for distributed systems using a multigrid method [PDF]
The problem of estimating spatially varying coefficients of partial differential equations is considered from observation of the solution and of the right hand side of the equation.

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Comparison Theorem for Nonlinear Path-Dependent Partial Differential Equations
Abstract and Applied Analysis, 2014 We introduce a type of fully nonlinear path-dependent (parabolic) partial differential equation (PDE) in which the path ωt on an interval [0, t] becomes the basic variable in the place of classical variables t,x∈[0,T]×ℝd.

Advanced Science, EarlyView.Super‐stretchable and self‐healing polyacrylate ternary ionogel elastomers are used for flexible i‐TE devices. Based on Gutmann donor theory of doped anion, the work proposes a three‐parameter tuning strategy of flexible polymer‐doped anion‐synergistic cation to achieve the systematic design of ionic thermoelectric materials. Abstract Quasi‐solid‐state,

Degenerate parabolic stochastic partial differential equations
Stochastic Processes and their Applications, 2013 Dans cette thèse, on considère des problèmes issus de l'analyse d'EDP stochastiques paraboliques non-dégénérées et dégénérées, de lois de conservation hyperboliques stochastiques, et d'EDS avec coefficients continus. Dans une première partie, on s'intéresse à des EDPS paraboliques dégénérées- on adapte les notions de formulation et de solutions ...

Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation
Advanced Science, EarlyView.The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
