Prescription of Gauss curvature on compact hyperbolic orbifolds [PDF]
Discrete & Continuous Dynamical Systems - A, 2014 This paper is organized in the following way: Section 1 contains preliminaries and the problem of prescribing the Gauss curvature of convex sets in the Minkowski spacetime, which is a generalization of a result by Alexandrov for Euclidean convex bodies.

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

The Gauss map in spaces of constant curvature [PDF]
Proceedings of the American Mathematical Society, 1973 Let N N be a complete simply connected Riemannian manifold of constant sectional curvature ≠ 0 \ne 0 . Let M M be an immersed Riemannian hypersurface of N N . The Gauss map on M M based at a point p p in N N is ...

Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers
Small, EarlyView.Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...

Exterior Dirichlet Problem for Translating Solutions of Gauss Curvature Flow in Minkowski Space
Abstract and Applied Analysis, 2014 We prove the existence of solutions to a class of Monge-Ampère equations on exterior domains in ℝn(n≥2) and the solutions are close to a cone. This problem comes from the study of the flow by powers of Gauss curvature in Minkowski space.

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene
Small, EarlyView.Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

A Novel Approach to Energy Management in Electric Steelworks
steel research international, EarlyView.Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

Development of ± 550 kV DC GIS Basin Insulator
High Voltage, EarlyView.ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.
