Hilbert Metric in the Unit Ball [PDF]
The Hilbert metric between two points š„, š¦ in a bounded convex domain šŗ is defined as the logarithm of the cross-ratio š„, š¦ and the intersection points of the Euclidean line passing through the points š„, š¦ and the boundary of the domain.

Triangular ratio metric in the unit disk [PDF]
The triangular ratio metric is studied in a domain , . Several sharp bounds are proven for this metric, especially in the case where the domain is the unit disk of the complex plane.

Unit-cell volume change as a metric of radiation damage in crystals of macromolecules. [PDF]
The use of third-generation synchrotron sources has led to renewed interest in the effect that ionizing radiation has on crystalline biological materials. Simple criteria have been sought to study the effects systematically.

Critical review of the levelised cost of energy metric
The purpose of this paper is to critically review the ālevelised cost of energyā metric used in electricity project development. This metric is widely used, because it is a simple metric to calculate the cost per unit of electricity for a given ...

Radial balanced metrics on the unit disk
Let $ $ be a strictly plurisubharmonic and radial function on the unit disk ${\cal D}\subset {\complex}$ and let $g$ be the \K metric associated to the \K form $ =\frac{i}{2}\partial\bar\partial $. We prove that if $g$ is $g_{eucl}$-balanced of height 3 (where $g_{eucl}$ is the standard Euclidean metric on ${\complex}={\real}^2$), and the function ...

Wassersteināmetricābased distributionally robust optimization method for unit commitment considering wind turbine uncertainty [PDF]
The penetration of wind turbines in the power grid is increasing rapidly. Still, the wind turbine output power has uncertainty, leading to poor grid reliability, affecting the grid's dispatching plan, and increasing the total cost.

Scalar curvature of a metric with unit volume
For a compact n-manifold M equipped with a conformal class C of Riemannian metrics, \(\mu\) (M,C) is defined as the infimum of the Yamabe functional; \(\mu (M,C)=\inf \{\int _{M}R_ gdv_ g;\quad g\in C\quad and\quad Vol(M,g)=1\},\) where \(R_ g\) is the scalar curvature of g. Let \(\mu (M)=\sup _{C}\mu (M,C)\). Then the set \({\mathcal S}(M)=\{R_ g\in C^

Threshold units: A correct metric for reaction time? [PDF]
To compare reaction time (RT) to rod incremental and decremental stimuli expressed in physical contrast units or psychophysical threshold units.Rod contrast detection thresholds and suprathreshold RTs were measured for Rapid-On and Rapid-Off ramp stimuli.Threshold sensitivity to Rapid-Off stimuli was higher than to Rapid-On stimuli.

Defining an adequate unit size is often crucial in brain imaging analysis, where datasets are complex, high-dimensional, and computationally demanding. Unit size refers to the spatial resolution at which brain data is aggregated for analysis.
