bcn compounds have been researched theoretically and experimentally widely. in this paper, weintroduce the theoretical prediction of ternary b-c-n compounds. nmr spectroscopy was employedextensively to study these ternary nanostructures. we discuss the utilization of chemical shiftinformation as well as ab initio calculations of nuclear shielding for h20134c9n4 structuredetermination. we calcul...

rockfill dams are accounted as useful measures in watershed management projects. how-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures however; there is no general relationship to estimate the sediment transport rat...

conclusion the study evaluated the biomechanical properties of the on and peripapillary structures in vivo with swe in glaucoma. we observed stiffer on and peripapillary tissue in glaucomatous eyes, indicating that swe claims new perspectives in the evaluation of on and peripapillary structures in glaucoma disease. background primary open-angle glaucoma is a multifactorial serious disease chara...

in this paper, we establish the theory of fuzzy ideal convergence on completely distributive lattices and give characterizations of some topological notions. we also study fuzzy limit structures and discuss the relationship between fuzzy co-topologies and fuzzy limit structures.

Classical limits of quantum groups give rise to multiplicative Poisson structures such as Poisson-Lie and quasi-Poisson structures. We relate them the notion a shifted structure which gives conceptual framework for understanding classical (dynamical) r -matrices, groupoids so on. also propose symplectic realization show that Manin pairs triples examples such.

In this paper, we first study infinitesimal deformations of a Lie conformal algebra and with module (called an [Formula: see text] pair), which lead to the notions Nijenhuis operator on structure pair, respectively. Then, by adding compatibility conditions between structures text]-operators, introduce notion text]-structure pair show that gives rise hierarchy pairwise compatible text]-operators...
