Mapping stacks of topological stacks [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2010 We prove that the mapping stack Map(Y,X) of topological stacks X and Y is again a topological stack if Y admits a compact groupoid presentation. If Y admits a locally compact groupoid presentation, we show that Map(Y,X) is a paratopological stack. In particular, it has a classifying space (hence, a natural weak homotopy type).

Stacking sensitive topological phases in a bilayer Kane-Mele-Hubbard model at quarter filling
, 2019 Layered quasi two dimensional systems have garnered huge interest both in the advancement of technology and in understanding emergent physics such as unconventional superconductivity, topological phases. In particular, the study of topological properties

Bending modes, elastic constants and mechanical stability of graphitic systems [PDF]
, 2010 The thermodynamic and mechanical properties of graphitic systems are strongly dependent on the shear elastic constant C44. Using state-of-the-art density functional calculations, we provide the first complete determination of their elastic constants and ...

Stacking data analysis method for Langmuir multi-probe payload
Frontiers in Astronomy and Space SciencesThere are numerous small-scale electron density irregularities in the ionosphere. The coordination of multiple needle Langmuir probes (m-NLPs) enables in situ measurement of electron density with high spatial resolution. However, the theoretical analysis

A Stacking-Based Model for Non-Invasive Detection of Coronary Heart Disease
IEEE Access, 2020 Coronary arteriongraphy (CAG) is an accurate invasive technique for the diagnosis of coronary heart disease (CHD). However, its invasive procedure is not appropriate for the detection of CHD in the annual physical examination.

Magnetism of two-dimensional defects in Pd: stacking faults, twin boundaries and surfaces
, 2006 Careful first-principles density functional calculations reveal the importance of hexagonal versus cubic stacking of closed packed planes of Pd as far as local magnetic properties are concerned.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
