Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

open access: yesAdvanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Automated computation of robust normal forms of planar analytic vector fields

open access: yes, 2008
We construct an auto-validated algorithm that calculates a close to identity change of variables which brings a general saddle point into a normal form.

Iterative Methods for Double Saddle Point Systems

open access: yesSIAM Journal on Matrix Analysis and Applications, 2018
We consider the iterative solution of a class of linear systems with double saddle point structure. Several block preconditioners for Krylov subspace methods are described and analyzed.

The Versatility of Layered Two‐Dimensional Heterostructures for Energy Storage: Bridging Scientific Insights and Practical Applications

open access: yesAdvanced Materials, EarlyView.
This review highlights the potential of 2D‐2D heterostructures (HRs) in advancing monovalent ion‐based energy storage. It examines their role in tailoring charge interactions mechanisms, optimizing interfacial properties, and overcoming the limitations of individual layered materials.

Saddled by the Saddle Nose: A Case of Wegener's Granulomatosis

open access: yesClinical Dermatology Review
Wegener's Granulomatosis with polyangiitis (GPA) is a systemic disease of unknown etiology characterized by necrotizing granulomatous inflammation, tissue necrosis, and variable degrees of vasculitis in small- and medium-sized blood vessels. The classical clinical triad consists of involvement of the upper airways, lungs, and kidneys.

Exact results in a slave boson saddle point approach for a strongly correlated electron model

open access: yes, 2008
We revisit the Kotliar-Ruckenstein (KR) slave boson saddle point evaluation for a two-site correlated electron model. As the model can be solved analytically, it is possible to compare the KR saddle point results to the exact many particle levels.
