Study the Behavior of Drug Structures via Chemical Invariants Using TOPSIS and SAW. [PDF]
Comput Math Methods Med, 2023 Every year, various experiments emerge in which a strong link between topological chemical structures and their properties is found. These properties are numerous such as melting point, boiling point, and drug toxicity. Topological index is the functional tool to determine these properties.

A Maximum Resonant Set of Polyomino Graphs
Discussiones Mathematicae Graph Theory, 2016 A polyomino graph P is a connected finite subgraph of the infinite plane grid such that each finite face is surrounded by a regular square of side length one and each edge belongs to at least one square.

Minimum area polyomino Venn diagrams
Journal of Computational Geometry, 2012 Polyomino Venn (or polyVenn) diagrams are Venn diagrams whose curves are the perimeters of orthogonal polyominoes drawn on the integer lattice. Minimum area polyVenn diagrams are those in which each of the 2n intersection regions, in a diagram of n ...

Boosting Photovoltaic Respond Through Molecular Engineering in Organic Manganese (II) Bromide for High-Sensitivity X‑Ray Detection. [PDF]
Adv Sci (Weinh)This work successfully synthesized novel 0D Mn2⁺‐based metal halides (MHs) PTA2MnBr4 and DMA2MnBr4 wafers by a precise molecular design the distance between Mn atoms. The larger PTA⁺ benzene ring structure reduces energy transfer. Importantly, the X‐ray detector based on PTA2MnBr4 wafers achieved the high sensitivity of 1122 µC Gyair−1 cm−2, an low LoD

Low Complexity, Low Probability Patterns and Consequences for Algorithmic Probability Applications
Complexity, Volume 2023, Issue 1, 2023., 2023 Developing new ways to estimate probabilities can be valuable for science, statistics, engineering, and other fields. By considering the information content of different output patterns, recent work invoking algorithmic information theory inspired arguments has shown that a priori probability predictions based on pattern complexities can be made in a ...

Combinatorics of non-ambiguous trees [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 This article investigates combinatorial properties of non-ambiguous trees. These objects we define may be seen either as binary trees drawn on a grid with some constraints, or as a subset of the tree-like tableaux previously defined by Aval, Boussicault ...

Helly Numbers of Polyominoes [PDF]
Graphs and Combinatorics, 2012 We define the Helly number of a polyomino $P$ as the smallest number $h$ such that the $h$-Helly property holds for the family of symmetric and translated copies of $P$ on the integer grid. We prove the following: (i) the only polyominoes with Helly number 2 are the rectangles, (ii) there does not exist any polyomino with Helly number 3, (iii) there ...

A Technique for the Array Partitioning
Radio Science, Volume 57, Issue 10, October 2022., 2022 Abstract A first stage of a sub‐array synthesis method is presented. The approach refers to a continuous aperture radiating multiple beams thanks to a phase‐only control and its aim is to determine the optimal partitioning of an aperture into sub‐apertures fed with a constant phase. The technique is based on a multi‐stage approach.
