• Tissue drives lesion: computational evidence of interspecies variability in cardiac radiofrequency ablation 

  Petras A.; Leoni M.; Guerra J.M.; Jansson J.; Gerardo-Giorda L. (HE 10TH INTERNATIONAL CONFERENCE ON FUNCTIONAL IMAGING AND MODELING OF THE HEART, 2019)

  Radiofrequency catheter ablation (RFCA) is widely used for the treatment of various types of cardiac arrhythmias. Typically, the efficacy and the safety of the ablation protocols used in the clinics are derived from tests ...

• Bloom type upper bounds in the product BMO setting 

  Li K.; Martikainen H.; Vuorinen E. (Journal of Geometric Analysis, 2019-04-08)

  We prove some Bloom type estimates in the product BMO setting. More specifically, for a bounded singular integral $T_n$ in $\mathbb R^n$ and a bounded singular integral $T_m$ in $\mathbb R^m$ we prove that $$ \| [T_n^1, ...

• Convex Integration Arising in the Modelling of Shape-Memory Alloys: Some Remarks on Rigidity, Flexibility and Some Numerical Implementations 

  Rüland, A.; Taylor J. M.; Zillinger, C. (Journal of Nonlinear Science, 2019-03-30)

  We study convex integration solutions in the context of the modelling of shape-memory alloys. The purpose of the article is twofold, treating both rigidity and flexibility prop- erties: Firstly, we relate the maximal ...

• Adjoint-based formulation for computing derivatives with respect to bed boundary positions in resistivity geophysics 

  Chaumont-Frelet T.; Shahriari M.; Pardo D. (Computational Geosciences, 2019-02)

  In inverse geophysical resistivity problems, it is common to optimize for specific resistivity values and bed boundary positions, as needed, for example, in geosteering applications. When using gradient-based inversion ...

• Topological singular set of vector-valued maps, I: application to manifold-constrained Sobolev and BV spaces 

  Canevari G.; Orlandi G. (Calculus of Variations and Partial Differential Equations, 2019-03-30)

  We introduce an operator $\mathbf{S}$ on vector-valued maps $u$ which has the ability to capture the relevant topological information carried by $u$. In particular, this operator is defined on maps that take values in a ...
