Timelike Circular Surfaces and Singularities in Minkowski 3-Space

Symmetry, Journal Year: 2022, Volume and Issue: 14(9), P. 1914 - 1914

Published: Sept. 13, 2022

The present paper is focused on time-like circular surfaces and singularities in Minkowski 3-space. timelike surface with a constant radius could be swept out by moving Lorentzian circle its center while following non-lightlike curve called the spine curve. In study, we have parameterized examined their geometric properties, such as striction curves, corresponding those of ruled surfaces. After that, different kind was determined named roller coaster surface. Meanwhile, support results this work some examples.

An Operational DNA Strand Displacement Encryption Approach

Nanomaterials, Journal Year: 2022, Volume and Issue: 12(5), P. 877 - 877

Published: March 6, 2022

DeoxyriboNucleic Acid (DNA) encryption is a new method that appeared along with the research of DNA nanotechnology in recent years. Due to complexity biology nanotechnology, brings an additional difficulty deciphering and, thus, can enhance information security. As approach strand displacement has particular advantages such as being enzyme free and self-assembly. However, existing on DNA-strand-displacement-based mostly stayed at theoretical or simulation stage. To this end, paper proposes framework. This framework involves three main strategies. The first strategy was tri-phase conversion from plaintext sequences according Huffman-coding-based transformation rule, which enhances concealment information. second development molecular modules, produce initial key for encryption. third cyclic-shift-based operation extend long enough, thus increase difficulty. results biological experiments demonstrated feasibility our scheme further validated terms sensitivity, space, statistic characteristic. Our provides potential way realize via promotes

ICDM-GEHC: identifying cancer driver module based on graph embedding and hierarchical clustering

Complex & Intelligent Systems, Journal Year: 2024, Volume and Issue: 10(3), P. 3411 - 3427

Published: Feb. 3, 2024

Abstract Due to the high heterogeneity of cancers, it is rather essential explore driver modules with help gene mutation data as well known interactions between genes/proteins. Unfortunately, latent false positive are inevitable in Protein-Protein Interaction (PPI) network. Hence presented method, a new weight evaluation index, based on gene-microRNA network somatic profile, introduced for weighting PPI first. Subsequently, vertices weighted hierarchically clustered by measuring Mahalanobis distance their feature vectors, extracted graph embedding method Node2vec. Finally, heuristic process dropping and extracting conducted clusters produce group modules. Numerous experiment results demonstrate that proposed exhibits superior performance four cutting-edge identification methods most cases regarding capability recognizing acknowledged cancer-related genes, generating having relatively coverage mutual exclusivity, significantly enriched specific types cancers. The majority genes identified involved signaling pathways, or have been reported be carcinogenic literature. Furthermore, many cancer related detected actually omitted comparison methods, which has verified experiments.

Binomial Distributed Data Confidence Interval Calculation: Formulas, Algorithms and Examples

Symmetry, Journal Year: 2022, Volume and Issue: 14(6), P. 1104 - 1104

Published: May 27, 2022

When collecting experimental data, the observable may be dichotomous. Sampling (eventually with replacement) thus emulates a Bernoulli trial leading to binomial proportion. Because distribution is discrete, analytical evaluation of exact confidence interval sampled outcome mathematical challenge. This paper proposes three alternative calculation methods that are characterized and exemplified.
