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.

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.

Gauss curvature flow: the fate of the rolling stones
, 2015 We prove Firey's 1974 conjecture that convex surfaces moving by their Gauss curvature become spherical as they contract to ...

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters
The RAND Journal of Economics, EarlyView.ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

CURVATURE AND GAUSS-BONNET DEFECT OF GLOBAL AFFINE HYPERSURFACES
, 2008 . The total curvature of complex hypersurfaces in C n+1 and its variation in families appear to depend not only on singularities but also on the behaviour in the neighbourhood of infinity.

Gauss curvature flow on surfaces of revolution: a noncompact problem
This is an open access article under the CC BY license.Earlier work of the first author [15] examined two boundary value problems associated to the Gauss Curvature Flow on a surface of revolution generated by a positive, differentiable function on a ...

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain
Acta Zoologica, EarlyView.ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.

Non-local curvature and Gauss–Bonnet cosmologies by Noether symmetries
, 2020 Non-local gravity cosmologies are considered under the standard of Noether symmetry approach. In particular, we focus on non-local theories whose gravitational actions depend on curvature and Gauss–Bonnet scalar invariants.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...
