The Optimal Transportation Method in Solid Mechanics [PDF]

open access: yes, 2009
This dissertation is concerned with the development of a robust and efficient meshless method, the Optimal Transportation Method (OTM), for general solid flows involving extremely large deformation, fast, transient loading and hydrodynamic phenomena ...

Mixed formulation of elliptic variational inequalities and its approximation [PDF]

open access: yes, 1981
summary:The approximation of a mixed formulation of elliptic variational inequalities is studied. Mixed formulation is defined as the problem of finding a saddle-point of a properly chosen Lagrangian $\Cal 2$ on a certain convex set $Kx \ \Lambda ...

Sensitivity analysis and parameter estimation for distributed hydrological modeling: potential of variational methods [PDF]

open access: yes, 2009
Variational methods are widely used for the analysis and control of computationally intensive spatially distributed systems. In particular, the adjoint state method enables a very efficient calculation of the derivatives of an objective function ...

An adaptive finite element approximation of a variational model of brittle fracture [PDF]

open access: yes, 2010
The energy of the Francfort–Marigo model of brittle fracture can be approximated, in the sense of Gamma-convergence, by the Ambrosio–Tortorelli functional.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

A Viscoelastic Contact Problem with Adhesion and Surface Memory Effects

open access: yesMathematical Modelling and Analysis, 2014
We consider a mathematical model which describes the quasistatic contact between a viscoelastic body and an obstacle, the so-called foundation. The material's behavior is modelled with a constitutive law with long memory.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

An Extended Variational Formulation for Isothermal Gas-Dynamic Lubrication [PDF]

open access: yes, 1970
An extended variational formulation is derived which can be applied to problems in isothermal compressible flow where the medium obeys the perfect gas law.

A Variational Formulation for Fins with Nonzero Contact Thermal Resistance at the Base

open access: yesAxioms, 2023
This paper considers the steady-state heat transfer process in a fin with a Robin boundary condition at the base (instead of the usual Dirichlet boundary condition at the base). Robin boundary condition models the effect of the thermal resistance between
