Natural Paracontact Magnetic Trajectories on Unit Tangent Bundles

open access: yesAxioms, 2020
In this paper, we study natural paracontact magnetic trajectories in the unit tangent bundle, i.e., those that are associated to g-natural paracontact metric structures.

Theorizing Trikāla: A Generalized Intervallic Approach to Pulse Transformation in South Indian Carnatic Music [PDF]

open access: yesAnalytical Approaches to World Music, 2020
The rich rhythmic/metric construction of South Indian Carnatic music is characterized, in large part, by intricate interplay between an internalized metric cycle called the tāḷa and performed phrases that may generate expressive tension with this tāḷa ...

Curvature exponent and geodesic dimension on Sard-regular Carnot groups

open access: yesAnalysis and Geometry in Metric Spaces
In this study, we characterize the geodesic dimension NGEO{N}_{{\rm{GEO}}} and give a new lower bound to the curvature exponent NCE{N}_{{\rm{CE}}} on Sard-regular Carnot groups.

The nature of ligand efficiency

open access: yesJournal of Cheminformatics, 2019
Ligand efficiency is a widely used design parameter in drug discovery. It is calculated by scaling affinity by molecular size and has a nontrivial dependency on the concentration unit used to express affinity that stems from the inability of the ...

Metric quasiconformality and Sobolev regularity in non-Ahlfors regular spaces

open access: yesAnalysis and Geometry in Metric Spaces
Given a homeomorphism f:X→Yf:X\to Y between QQ-dimensional spaces X,YX,Y, we show that ff satisfying the metric definition of quasiconformality outside suitable exceptional sets implies that ff belongs to the Sobolev class Nloc1,p(X;Y){N}_{{\rm{loc}}}^{1,

A Class of New Metrics for n-Dimensional Unit Hypercube

open access: yesJournal of Applied Mathematics, 2013
We study the metric on the n-dimensional unit hypercube. We introduce a class of new metrics for the space, which is information theoretically motivated and has close relation to Jensen-Shannon divergence.

On non-commutative Minkowski spheres

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
The purpose of the following is to try to make sense of the stereo- graphic projection in a non-commutative setup. To this end, we consider the open unit ball of a ternary ring of operators, which naturally comes equipped with a non-commutative version ...

Characterization of Clifford Torus in Three-Spheres

open access: yesMathematics, 2020
We characterize spheres and the tori, the product of the two plane circles immersed in the three-dimensional unit sphere, which are associated with the Laplace operator and the Gauss map defined by the elliptic linear Weingarten metric defined on closed ...
