An Improved Upper Bound on Neighbor Expanded Sum Distinguishing Index
Discussiones Mathematicae Graph Theory, 2020 A total k-weighting f of a graph G is an assignment of integers from the set {1, . . . , k} to the vertices and edges of G. We say that f is neighbor expanded sum distinguishing, or NESD for short, if Σw∈N(v) (f(vw) + f(w)) differs from Σw∈N(u)(f(uw) + f(

The distinguishing number and the distinguishing index of co-normal product of two graphs
Ratio Mathematica, 2019 The distinguishing number (index) $D(G)$ ($D'(G)$) of a graph $G$ is the least integer $d$ such that $G$ has an vertex labeling (edge labeling) with $d$ labels that is preserved only by a trivial automorphism.

Corneal biomechanics in normal and subclinical keratoconus eyes
BMC Ophthalmology, 2023 Background The diagnosis of keratoconus, as the most prevalent corneal ectatic disorder, at the subclinical stage gained great attention due to the increased acceptance of refractive surgeries.

Evaluation of corneal topographic, tomographic and biomechanical indices for detecting clinical and subclinical keratoconus: a comprehensive three-device study [PDF]
International Journal of Ophthalmology, 2021 AIM: To evaluate the diagnostic ability of topographic and tomographic indices with Pentacam and Sirius as well as biomechanical parameters with Corvis ST for the detection of clinical and subclinical forms of keratoconus (KCN).

Leveraging deep learning to identify calcification and colloid in thyroid nodules
Heliyon, 2023 Background: Both calcification and colloid in thyroid nodules are reflected as echogenic foci in ultrasound images. However, calcification and colloid have significantly different probabilities of malignancy.

Using the parcel shape index to determine arable land division types
Acta Geographica Slovenica, 2019 This paper presents a new index for determining the shape of land parcels. Parcel shapes are usually represented descriptively (i.e. ribbon-shaped, rectangular, irregularly shaped), which is useless for automated distinguishing between parcel shapes or ...

An unusual growth in the nail matrix: A case of superficial acral fibromyxoma
Skin Health and Disease, 2022 We describe a case of superficial acral fibromyxoma arising within the germinal matrix of the index finger. This is an uncommon localisation of this relatively newly described benign soft tissue tumour. Herein, we discuss the varied clinical presentation,

A note on the vertex-distinguishing index for some cubic graphs [PDF]
Opuscula Mathematica, 2004 The vertex-distinguishing index of a graph \(G\) (\(\operatorname{vdi}(G)\)) is the minimum number of colours required to colour properly the edges of a graph in such a way that any two vertices are incident with different sets of colours.
