Role of Non-Covalent Interactions in Novel Supramolecular Compound, Bis(4-phenylpiperazin-1-ium) Oxalate Dihydrate: Synthesis, Molecular Structure, Thermal Characterization, Spectroscopic Properties and Quantum Chemical Study

Crystals, 2023
The stoichiometric ratio 2:1 mix of 1-phenylpiperazine and oxalic acid dihydrate followed by slow evaporation results in a new material, bis(4-phenylpiperazin-1-ium) oxalate dihydrate, with the general chemical formula (C10H15N2)2(C2O4).2H2O, indicated ...

Galois orbits of TQFTs: symmetries and unitarity

Journal of High Energy Physics, 2022
We study Galois actions on 2+1D topological quantum field theories (TQFTs), characterizing their interplay with theory factorization, gauging, the structure of gapped boundaries and dualities, 0-form symmetries, 1-form symmetries, and 2-groups.

Impact of Variable Speed on Collective Movement of Animal Groups

Frontiers in Physics, 2021
The collective dynamics and structure of animal groups has attracted the attention of scientists across a broad range of fields. A variety of agent-based models have been developed to help understand the emergence of coordinated collective behavior from ...

The evolutionary dynamics of protein-protein interaction networks inferred from the reconstruction of ancient networks. [PDF]

PLoS ONE, 2013
Cellular functions are based on the complex interplay of proteins, therefore the structure and dynamics of these protein-protein interaction (PPI) networks are the key to the functional understanding of cells.

Anomaly matching in the symmetry broken phase: Domain walls, CPT, and the Smith isomorphism

SciPost Physics, 2020
Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes or a topological field theory. If the symmetry is spontaneously broken,

Facial one-pot synthesis of D3h symmetric bicyclocalix[2]arene[2]triazines and their layered comb self-assembly

Journal of Saudi Chemical Society, 2018
A number of D3h symmetric bicyclocalix[2]arene[2]triazine core compounds were synthesized via a general and good-yielding (43–48% yield) facile protocol starting from cyanuric halides, phloroglucinol and K2CO3 under very mild reaction conditions.
