From Molecule to Meaning: Click and Bioorthogonal Chemical Reporters for Plant Systems, Biological Imaging, and Artistic Expression. [PDF]

Chembiochem
At the intersection of chemical biology, plant imaging, and contemporary art, this review introduces the concept of chembioart. By tracing how chemical reporters illuminate plant biomolecules in vivo, their role not only in advancing scientific understanding but also in inspiring transdisciplinary collaborations and visual expression is highlighted ...

New Semi-Prime Factorization and Application in Large RSA Key Attacks

Journal of Cybersecurity and Privacy, 2021
Semi-prime factorization is an increasingly important number theoretic problem, since it is computationally intractable. Further, this property has been applied in public-key cryptography, such as the Rivest–Shamir–Adleman (RSA) encryption systems for ...

An application of p-adic Baker method to a special case of Jeśmanowicz' conjecture

AIMS Mathematics, 2023
In 1956, Jeśmanowicz conjectured that, for any positive integer $ n $, the Diophantine equation $ \left((f^{2}-g^{2})n\right)^{x}+\left((2fg)n\right)^{y} = \left((f^{2}+g^{2})n\right)^z $ has only the positive integral solution $ (x, y, z) = (2, 2, 2) $,

Pythagorean Isoparametric Hypersurfaces in Riemannian and Lorentzian Space Forms

Axioms, 2022
We introduce the notion of a Pythagorean hypersurface immersed into an n+1-dimensional pseudo-Riemannian space form of constant sectional curvature c∈−1,0,1.

Role of preoperative transarterial chemoembolization (TACE) in intermediate-stage hepatocellular carcinoma (Hong Kong liver cancer stage IIB). [PDF]

World J Surg
Abstract Introduction Transarterial chemoembolization (TACE) has an established role in advanced HCC. The present study evaluates the role of TACE as a neoadjuvant modality in the management of intermediate HCC [Hong Kong Liver Cancer (HKLC) stage IIB].

Incremental and Transitive Discrete Rotations [PDF]

, 2006
A discrete rotation algorithm can be apprehended as a parametric application $f\_\alpha$ from $\ZZ[i]$ to $\ZZ[i]$, whose resulting permutation ``looks like'' the map induced by an Euclidean rotation.

Interval-valued Pythagorean Fuzzy Frank Power Aggregation Operators based on An Isomorphic Frank Dual Triple

International Journal of Computational Intelligence Systems, 2018
Interval-valued Pythagorean fuzzy sets (PFSs), as an extension of PFSs, have strong potential in the management of complex uncertainty in real-world applications.

An Extended Kannan Contraction Mapping and Applications [PDF]

International Journal of Mathematical, Engineering and Management Sciences
We extend the Kannan contraction principle and obtain a result that holds for both contractive and non-expansive mappings. Such mappings admit multiple fixed-points and the fixed-point sets and domains of these mappings display interesting algebraic ...

Generalized Pythagorean Triples and Pythagorean Triple Preserving Matrices

Missouri Journal of Mathematical Sciences, 2009
Traditionally, Pythagorean triples (PT) consist of three positive integers, $(x, y, z) \in \mathbb{Z}^3_+$, such that $x^2 + y^2 = z^2$, and Pythagorean triple preserving matrices (PTPM) $A$ are $3 \times 3$ matrices with entries in the real numbers $\R$, such that the product $(x, y, z)A$ is also a Pythagorean triple.

3D investigation and modeling of the geometric effects on porosity in packed beds

AIChE Journal, EarlyView.
Abstract In porous beds, physical boundaries restrict particle arrangement, leading to inhomogeneous porosity. This paper reports on the porosity profiles that are the result of geometric effects on monodisperse packed beds in cylindrical and cubic arrangements. Special focus is given to the influence of edges and corners in cubic geometries.
