in this study, the radial distribution and gravimetric storage capacities of hydrogen on coronene (c24h12) and its si substituted forms, c24h12, c24-nsinh12 (n= 4-24), have been investigated at 298 k and 0.1 mpa (standard situation) using (n,v,t) monte carlo simulation by lennard-jones (lj) 12-6 potential. the results show that the increase of number of silicon substitution doesn’t have any eff...

torsion of many symmetric structures, which were designed based on the seismic codes, is due to their asymmetricity induced during inelastic behavior. although the structure was designed symmetrically assuming elastic based criteria, different factors such as material inconsistency in structure, construction details discrepancy and construction errors may result in asymmetric behavior in inelas...

Nucleosomes in active chromatin are dynamic, but whether they have distinct structural conformations is unknown. To identify nucleosomes with alternative structures genome-wide, we used H4S47C-anchored cleavage mapping, which revealed that 5% of budding yeast (Saccharomyces cerevisiae) nucleosome positions have asymmetric histone-DNA interactions. These asymmetric interactions are enriched at n...

A wavelength band-pass filter with asymmetric dual circular ring resonators in a metal-insulator-metal (MIM) structure is proposed and numerically simulated. For the interaction of the local discrete state and the continuous spectrum caused by the side-coupled resonators and the baffle, respectively, the transmission spectrum exhibits a sharp and asymmetric profile. By adjusting the radius and ...

Peptides as a kind of important chiral scaffold are broadly identified for their obvious advantages, diverse structures and accessibility. Based on promiscuous aldo-keto-reductase enzymes, several mimetic peptides were designed which were synthesized and tested as multifunctional organocatalysts in direct asymmetric aldol reactions. The corresponding aldol products were produced with high yield...

Chromosome separation and segregation must be executed within a bacterial cell in which the membrane and cytoplasm are highly structured. Here, we develop a strand-specific model based on each of the future daughter chromosomes being associated with a different set of structures or hyperstructures in an asymmetric cell. The essence of the segregation mechanism is that the genes on the same stra...

Experiments on polycrystalline metallic samples have indicated that Grain boundary (GB) structure can affect many material properties related to fracture and plasticity. In this study, atomistic simulations are employed to investigate the structures and mechanical behavior of both symmetric and asymmetric ∑5[0 0 1] tilt GBs of copper bicrystal. First, the equilibrium GB structures are generated...

This paper compares three market structures in a dynamic dealer-mediated market with asymmetric information about an asset’s value. The compared market structures are (i) the continuous protocol of Glosten and Milgrom (1985), where a just-arrived trader trades immediately at a bid or an ask price publicly posted by the dealer, (ii) the periodic auction, wherein trades are cleared in batches, pu...

Bilateral animals, including humans and most metazoans, are not perfectly symmetrical. Some internal structures are distributed asymmetrically to the right or left side. A conserved Nodal and BMP signaling system directs molecular pathways that impart the sidedness to those asymmetric structures. In the sea urchin embryo, one such asymmetrical structure, oddly enough, is the entire adult, which...
