Network Filtering for Big Data: Triangulated Maximally Filtered Graph [PDF]
We propose a network-filtering method, the Triangulated Maximally Filtered Graph (TMFG), that provides an approximate solution to the WEIGHTED MAXIMAL PLANAR GRAPH problem. The underlying idea of TMFG consists in building a triangulation that maximizes a

Poliedarske forme nastale spajanjem omotača CP II-10 i zarubljenog dodekaedra [PDF]
The paper analyzes the possibility of obtaining polyhedral shapes formed by combining polyhedral surfaces based on the segment surface of elongated concave pyramids of the second sort (CeP II-10, type A and type B). In previous research, CP II type A and

The Wade's rules and Lipscomb's styx approach constitute a conceptual basis of chemical bonding in closo hydroborane clusters and similar compounds. Based on 3‐center electron sharing indices obtained from DFT wavefunctions, the DR approach for analysis of multicenter bonding in clusters and intermetallic compounds is presented.

Where Are the Elements in Complex Aluminides? An Experimental and Theoretical Investigation of the Quasicrystalline Approximants, Mg2-y(ZnxAl1-x)3+y [PDF]
The first detailed investigation of the crystalline R-phases in the Mg−Zn−Al ternary system is reported, which will assist with the interpretation and understanding of similar quasicrystalline phases in this phase diagram.

Reactivity studies of [Co@Sn9]4- with transition metal reagents: bottom-up synthesis of ternary functionalized zintl clusters [PDF]
The binary cluster [Co@Sn9]4– (1) was extracted directly from ethylenediamine (en) solutions of an intermetallic precursor with nominal composition “K5Co3Sn9”, and its reactions with various organometallic reagents were explored.

Quantum-chemical study of carborane(12) rearrangement mechanisms
The search and analysis of the ground state, intermediate and transition states of carborane(12) thermal isomerization was performed by means of quantum-chemistry methods using B3LYP/6-311+G(d,p) and M062X/6-311+G(d,p) functionals.

Single-crystal neutron diffraction study of metamict zircon up to 2000 K [PDF]
High-temperature single-crystal measurements of metamict zircon were performed up to 2000 K and the recrystallization was monitored using the width and intensity of selected peaks. Full data sets were collected at room temperature, 1573 and 1823 K.
