Application of hyperbolic geometry in link prediction of multiplex networks [PDF]
AbstractRecently multilayer networks are introduced to model real systems. In these models the individuals make connection in multiple layers. Transportation networks, biological systems and social networks are some examples of multilayer networks.

Birational Geometry of 3-fold Mori Fibre Spaces [PDF]
We study the geography and birational geometry of 3-fold conic bundles over P\(^2\) and cubic del Pezzo fibrations over P\(^1\).

Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

THE ROLE OF PROJECTIVE GEOMETRY IN TALIAN EDUCATION AND INSTITUTIONS AT THE END OF THE 19TH CENTURY
At the end of the 19th century, projective geometry was at the basis of most geometric research in Italy, and of much other research work in Europe. Furthermore, through its close connection with descriptive geometry, it seemed particularly responsive to

The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Bis(tribenzylammonium) tetrachloridoaurate(III) chloride
In the title compound, (C21H22N)2[AuCl4]Cl, the AuIII atom adopts a square-planar coordination geometry defined by four chloride ions. In the crystal structure, intermolecular N—H...Cl hydrogen bonds link the organic cations and the ...

Factorization in Phase-Space Finite Geometry and Weak Mutually Unbiased Bases
A phase-space factorization of lines in finite geometry G(m) with variables in Zm and its correspondence in finite Hilbert space H(m) for m a non-prime was discussed. Using the method of Good [15], lines in G(m) were factorized as products of lines G(mi)

Helicity, linking, and writhe in a spherical geometry
Linking numbers, helicity integrals, twist, and writhe all describe the topology and geometry of curves and vector fields. The topology of the space the curves and fields live in, however, can affect the behaviour of these quantities. Here we examine curves and fields living in regions exterior to a sphere or in spherical shells.
