Modern temporal network theory: A colloquium

The power of any kind of network approach lies in the ability to simplify a complex system so that one can better understand its function as a whole. Sometimes it is beneficial, however, to include more information than in a simple graph of only nodes and links. Adding information about times of interactions can make predictions and mechanistic understanding more accurate. The drawback, however, is that there are not so many methods available, partly because temporal networks is a relatively young field, partly because it more difficult to develop such methods compared to for static networks. In this colloquium, we review the methods to analyze and model temporal networks and processes taking place on them, focusing mainly on the last three years. This includes the spreading of infectious disease, opinions, rumors, in social networks; information packets in computer networks; various types of signaling in biology, and more. We also discuss future directions.Comment: Final accepted versio

Synthesis, biological, spectral and thermal properties of oxovanadium (IV) complexes of N,N,S-containing ligands

The reaction of VO2+ salts with 4[N-(2+-hydroxybenzalidene)amino/antipyrine thiosemicarbazone (HBAAPTS), 4[N-(2+-hydroxyl+-naphthalidene)amino/antipyrine thiosemicarbazone (HNAAPTS), 4[N-(cinnamalidene)amino/antipyrine thiosemicarbazone (CAAPTS) resulted in the formation of the complexes of the general composition VOX2L (X=Cl, Br, I, NO3 or NCS) and VO(ClO4)2.L.H2O (L= HBAAPTS, HNAAPTS or CAAPTS). The nature of the bonding and stereochemistry of the complexes have been deduced from elemental analysis, infrared, electronic spectra, magnetic susceptibility and conductance measurements. In all the oxovanadium(IV) complexes, the coordination number of central metal ion is five. The metal complexes were screened for their antifungal and antibacterial activities on different species of pathogenic fungi and bacteria respectively and their biopotency has been discussed
