Financial markets are a typical example of complex systems where interactions between constituents lead to many remarkable features. Here we give empirical evidence, by making as few assumptions as possible, that the market microstructure capturing almost all of the available information in the data of stock markets does not involve higher order than pairwise interactions. We give an economic i...

Almost all proteins contain charged residues, and their chain distribution is tailored to fulfill essential ionic interactions for folding, binding and catalysis. Among proteins, the hinged two-domain chain of the cellular prion protein (PrP(C)) exhibits a peculiar charge structure with unclear consequences in its structural malleability. To decipher the charge design role, we generated charge-...

The interplay of regular and chaotic elements in quantum many-body dynamics was extensively studied in the framework of random matrix theory and in realistic models of atoms, nuclei, condensed matter and quantum fields. The existence in finite systems of exact conservation laws, such as angular momentum, parity or isospin, raises new questions, for instance, how quantum chaos is influenced by t...

The spatial organisation of soils is crucially important in affecting belowground function, and the associated delivery of ecosystem services. Fungi constitute an important part of the soil biomass. As well as playing key roles in nutrient cycling and biotic interactions, they are also intimately involved in soil structural dynamics. Fungi mediate the formation of soil structure at a variety of...

MOTIVATION An ambitious goal of proteomics is to elucidate the structure, interactions and functions of all proteins within cells and organisms. The expectation is that this will provide a fuller appreciation of cellular processes and networks at the protein level, ultimately leading to a better understanding of disease mechanisms and suggesting new means for intervention. This paper addresses ...

the structural and energetic characteristics of o3–h2o complexes have been investigated by means of b3lyp, mp2, mp4(sdtq), ccsd(t) and qcisd(t) methods in conjunction with the aug-cc-pvdz and aug-cc-pvtz basis sets. six conformers were found for the o3–h2o complex. two different intermolecular interactions were expected to participate in the formation of complexes, namely conventional o∙∙∙h hyd...

studying the interaction of pharmaceutical ionic liquids with human serum albumin (hsa) can help investigating whether or not ionic liquid formation can enhance pharmacological profile of the discrete ingredients. in this respect, in the present work, the interactions of benzalkonium ibuprofenate, as a well-known active pharmaceutical ionic liquid, benzalkonium chloride, and also sodium ibuprof...

in traditional bazaars social interactions, parallel to economic and movement interactions, created a mixed urban space which was dynamic, lively and attractive to the audience. however, modern shopping centers and shopping malls are economy focused and void of variety of urban spaces like traditional bazaars. the presence of public open spaces and urban squares undetectable from traditional ba...

INTRODUCTION Hyaluronic acid (HA) is a major constituent of the extracellular matrix. Among its many biological functions, HA plays a critical role in cartilage, where large aggrecan-HA complexes that provide the resistance to compressive load enmesh the collagen network. The carboxyl groups of the HA molecule in physiological conditions become charged and contribute to the osmotic pressure of ...
