Adaptive Spline-based Finite Element Method with Application to Phase-field Models of Biomembranes
… both second- and fourth-order problems based on Nitsche's approach. The use of spline-based finite elements is further examined along with a Nitsche technique for enforcing constraints on an embedded interface. We show that how the choice of weights and stabilization parameters in the Nitsche …

Estructura intelectual de la estimulación cerebral no invasiva y sus principales técnicas. Un estudio bibliométrico
… y autores clave como Pascual-Leone, Rothwell, Nitsche y Fregni. Los indicadores estructurales muestran una red madura y cohesionada, donde los consensos acumulan citación, los estudios experimentales aportan centralidad y la densidad y proporción de nodos reflejan estabilidad. Temporalmente, …

Verstärkung des antinozizeptiven Effekts der kathodalen transkraniellen Gleichstromstimulation durch den Dopaminagonisten Pergolid
… erhöht und kathodale diese erniedrigt (Nitsche und Paulus 2000, 2001). In einem vorausgegangenen Experiment zeigte sich, dass kathodale Stromstimulation die Schmerzwahrnehmung herabsetzen kann (Csifcsak et al. 2009). Wir bewerteten die Wirkung der kathodalen tDCS einerseits anhand von …

Mollified piecewise polynomial approximants of arbitrary order and smoothness
… apply boundary conditions with the non-symmetric Nitsche method. The presented numerical examples confirm the optimal convergence of the proposed approximation scheme for Poisson and elasticity problems using finite element and collocation.

Optical Properties of Organic Semiconductors: from Submonolayers to Crystalline Films
We have measured the optical properties of films of the organic semiconductors PTCDA (3,4:9,10-perylene-tetracarboxylic dianhydride) and HBC (peri-hexabenzocoronene), prepared by Organic Molecular Beam Expitaxy (OMBE), on different substrates by means of Differential Reflectance Spectroscopy (DRS). …

Law and Rights in the Lives of Undocumented Migrant Women in the UK
The British state has introduced increasingly restrictive immigration legislation in recent years, as part of an effort to create a hostile environment for undocumented migrants. For instance, the 2014 and 2016 Immigration Acts further criminalise working without papers, renting property, and …

What goes up ... continues to go up : momentum in commercial real estate forecasting price appreciation via cap rates
In equity markets, dividend yields are highly correlated with future returns, largely through capital appreciation. Taking the same logic and applying it to the commercial real estate market -- could cap rates therefore predict future appreciation return? This paper finds that absolute cap rates …

Stable Embedded Grid Techniques in Computational Mechanics
… and show a less traditional method, known as Nitsche's method, to be a stable alternative. We address the open problem of applying Nitsche's method to non-linear analysis by drawing parallels between the embedded mesh and discontinuous Galerkin (DG) methods, and propose a DG style approach to …

A variational multiscale computational framework for nonlinear interfacial solid mechanics
This dissertation develops a robust computational framework for solving solid mechanics problems containing strong or weak discontinuities arising from interfaces. The framework consists of a stabilized version of the Discontinuous Galerkin method to handle interfaces combined with a stabilized …
