Non-convexity of extremal length [PDF]

open access: greenAnnales Fennici Mathematici, 2023
With respect to every Riemannian metric, the Teichmüller metric, and the Thurston metric on Teichmüller space, we show that there exist measured foliations on surfaces whose extremal length functions are not convex. The construction uses harmonic maps to \(\mathbb{R}\)-trees and minimal surfaces in \(\mathbb{R}^n\).

CLIMATE EXTREMES AND PREGNANCY LENGTH [PDF]

open access: bronzeISEE Conference Abstracts, 2011
Background and Aims: Although future climate is predicted to have more extreme heat conditions, the available evidence on the impact of these conditions on pregnancy is very scarce and inconclusive...

Conformal surface embeddings and extremal length

open access: diamondGroups, Geometry, and Dynamics, 2022
Given two Riemann surfaces with boundary and a homotopy class of topological embeddings between them, there is a conformal embedding in the homotopy class if and only if the extremal length of every simple closed multi-curve is decreased under the embedding.

Climate Extremes and the Length of Gestation

open access: diamondEnvironmental Health Perspectives, 2011
Although future climate is predicted to have more extreme heat conditions, the available evidence on the impact of these conditions on pregnancy length is very scarce and inconclusive.We investigated the impact of maternal short-term exposure to extreme ambient heat on the length of pregnancy.This study was based on a cohort of births that occurred in ...

On the first general Zagreb eccentricity index

open access: yesAIMS Mathematics, 2021
In a graph G, the distance between two vertices is the length of the shortest path between them. The maximum distance between a vertex to any other vertex is considered as the eccentricity of the vertex.

Extremal Curves in 2+1-Dimensional Yang-Mills Theory [PDF]

open access: yes, 1999
We examine the structure of the potential energy of 2+1-dimensional Yang-Mills theory on a torus with gauge group SU(2). We use a standard definition of distance on the space of gauge orbits.

Selection of worm gearing optimal structure for machine rotary table

open access: yesDiagnostyka, 2021
In this paper, the design of the machine rotary table with a kinematic worm gearing is research. A three-dimensional model of the rotary table assembly structure and the stress-strain state of the worm by the finite element method are researched ...

Extremely short-length surface plasmon resonance devices [PDF]

open access: yesOptics Express, 2008
The impact of the system design on the control of coupling between planar waveguide modes and surface plasmon polaritons (SPP) is analyzed. We examine how the efficiency of the coupling can be enhanced by an appropriate dimensioning of a multi-layer device structure without using additional gratings.
