Estimating lower probability bound of power system's capability to fully accommodate variable wind generation

The Journal of Engineering, 2019
As the penetration of wind generation increases, the uncertainty it brings has imposed great challenges to power system operation. To cope with the challenges, tremendous research work has been conducted, among which two aspects are of most importance ...

Spiritual Integration of Migrants: A Lisbon Case Study Within the Common Home Agenda and Polyhedron of Intelligibility Framework

Religions
Migration is a multidimensional process that reshapes identities and communities. This article adopts a polyhedral framework inspired by Pope Francis’s Laudato si’ and Michel Foucault’s concepts of “subjectivation” and the “polyhedron of intelligibility”.

Gate‐Tunable Hole Transport in In‐Plane Ge Nanowires by V‐Groove Confined Selective Epitaxy

Advanced Functional Materials, EarlyView.
Ge nanowires are promising for hole spin‐based quantum processors, requiring direct integration onto Si wafers. This work introduces V‐groove‐confined selective epitaxy for in‐plane nanowire growth on Si. Structural and low‐temperature transport measurements confirm their high crystalline quality, gate‐tunable hole densities, and mobility.

Connectivity calculus of fractal polyhedrons [PDF]

Pattern Recognition, 2015
The paper analyzes the connectivity information (more precisely, numbers of tunnels and their homological (co)cycle classification) of fractal polyhedra. Homology chain contractions and its combinatorial counterparts, called homological spanning forest (HSF), are presented here as an useful topological tool, which codifies such information and provides

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

Advanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.
