Similarity measures on cubic intuitionistic fuzzy sets [PDF]

open access: yesNotes on IFS
The primary objective of this study is to develop a similarity measure on cubic intuitionistic fuzzy sets. First, we have proposed a series of similarity measures on cubic intuitionistic fuzzy sets based on the geometric model, set-theoretic approach ...

On Representations of Divergence Measures and Related Quantities in Exponential Families

open access: yesEntropy, 2021
Within exponential families, which may consist of multi-parameter and multivariate distributions, a variety of divergence measures, such as the Kullback–Leibler divergence, the Cressie–Read divergence, the Rényi divergence, and the Hellinger metric, can ...

Mrk 1419 - a new distance determination

open access: yes, 2012
Water vapor megamasers from the center of active galaxies provide a powerful tool to trace accretion disks at sub-parsec resolution and, through an entirely geometrical method, measure direct distances to galaxies up to 200 Mpc.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gromov-Monge quasi-metrics and distance distributions

open access: yes, 2020
Applications in data science, shape analysis and object classification frequently require maps between metric spaces which preserve geometry as faithfully as possible.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

The Hubble Tension in Our Own Backyard: DESI and the Nearness of the Coma Cluster

open access: yesThe Astrophysical Journal Letters
The Dark Energy Spectroscopic Instrument (DESI) collaboration measured a tight relation between the Hubble constant ( H _0 ) and the distance to the Coma cluster using the fundamental plane (FP) relation of the deepest, most homogeneous sample of early ...

Dynamic Distance Measure on Spaces of Isospectral Mixed Quantum States

open access: yesEntropy, 2013
Distance measures are used to quantify the extent to which information is preserved or altered by quantum processes, and thus are indispensable tools in quantum information and quantum computing.

Notes on modified trace distance measure of coherence [PDF]

open access: yesQuantum Information Processing, 2017
We investigate the modified trace distance measure of coherence recently introduced in Yu et al. [Phys. Rev. A 94, 060302(R), 2016]. We show that for any single-qubit state, the modified trace norm of coherence is equal to the l1\documentclass[12pt ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.
