The quantum spin Hall effect disappears at high magnetic fields when the band inversion is lifted. The authors demonstrate that in contrast, in disordered samples, counter-propagating topological and quantum Hall edge channels prevent the detection o

The Dirac mass of a two-dimensional QAH insulator is directly related to the parity anomaly of planar quantum electrodynamics, as shown initially by Niemi and Semenoff [Phys. Rev. Lett. 51, 2077 (1983)PRLTAO0031-900710.1103/PhysRevLett.51.2077]. In t

We report magnetotransport studies on a gated strained HgTe device. This material is a three-dimensional topological insulator and exclusively shows surface-state transport. Remarkably, the Landau-level dispersion and the accuracy of the Hall quantiz

Tumor-derived protein tissue inhibitor of metalloproteinases-1 (TIMP1) correlates with poor prognosis in many cancers, including highly lethal pancreatic ductal adenocarcinoma (PDAC). The noncanonical signaling activity of TIMP1 is emerging as one ba

To support Hybrid Transaction and Analytical Processing (HTAP), database systems generally rely on Multi-Version Concurrency Control (MVCC). While MVCC elegantly enables lightweight isolation of readers and writers, it also generates outdated tuple v

The survival of the quantum spin Hall edge channels in presence of an external magnetic field has been a subject of experimental and theoretical research. The inversion of Landau levels that accommodates the quantum spin Hall effect is destroyed at a

Multi-core scalability is one of the most important features for database systems running on today's hardware. Not surprisingly, the implementation of locks is paramount to achieving efficient and scalable synchronization. In this work, we identify t
