Building Information Filtering Networks with Topological Constraints: Algorithms and Applications [PDF]

open access: yes, 2020
We propose a new methodology for learning the structure of sparse networks from data; in doing so we adopt a dual perspective where we consider networks both as weighted graphs and as simplicial complexes. The proposed learning methodology belongs to the

Zintl cluster chemistry in the alkali-metal-gallium systems [PDF]

open access: yes, 1998
Previous research into the alkali-metal-gallium systems has revealed a large variety of networked gallium deltahedra. The clusters are analogues to borane clusters and follow the same electronic requirements of 2n + 2 skeletal electrons for closo ...

Three-Dimensional Analogues of Kekule Structures in Borane Chemistry [PDF]

open access: yes, 1995
The topology of overlap of the atomic orbitals participating in the requisite delocalization for an aromatic system can be described by a graph, the eigenvalue spectrum of which can be related to molecular orbital energy parameters as determined by ...

Learning while playing - Througie platform for creating models of spatial structures [PDF]

open access: yes, 2023
The paper shows a way to create a set of tools that allows the construction of different models of spatial deltahedral structures as a result of the game.

Process Information Modelling (PIM) Concept for On-site Construction Management: Hong Kong Case [PDF]

open access: yes, 2018
When compared to the manufacturing industry, the advances of intelligent and seamless project management approaches lag behind in the construction industry.

Cluster expansion and vertex substitution pathways in nickel germanide Zintl clusters [PDF]

open access: yes
We describe the reactivity of the hypersilyl-functionalized Zintl cluster salt K[Ge$_9$ (Hyp)$_3$] towards the nickel reagents Ni(COD)$_2$ and Ni(Cp)$_2$, which gives rise to markedly different complexes. In the case of Ni(COD)$_2$ (COD
