Two novel lead(II) carboxyphosphonates with a layered and a 3D framework structure, namely, [Pb2Cl3(H2L)]·H2O (1) and [Pb2(HL)(HBTC)] (2) (H3L = H2O3PCH2-NC5H9-COOH, H3BTC = 1,3,5-benzenetricarboxylic acid), have been synthesized under hydrothermal conditions and structurally characterized. For compound 1, the interconnection of Pb(1)O2Cl3, Pb(2)O2Cl3, and CPO3 polyhedra via corner- and edge-sh...

Hydrogels with organized structure have attracted remarkable attentions for bio-related applications. Among the preparation of hierarchical hydrogel materials, fabrication of hydrogel with multi-layers is an important branch. Although the generation mechanism of layers had been fully discussed, sub-layer structure was not sufficiently studied. In this research, multi-layered chitosan hydrogel w...

The interplay between individuals forms building blocks for social structure. Here, we examine the structure of behavioral interactions among kindergarten classroom with a hierarchy-neutral approach to examine all possible underlying patterns in the formation of layered networks of "reciprocal" interactions. To understand how these layers are coordinated, we used a layered motif approach. Our d...

Thermal and structural austenite to martensite reversible transition was studied in melt spun ribbons of Ni50Mn40Sn5Co5, Ni50Mn37.5Sn7.5Co5 and Ni50Mn35Sn10Co5 (at. %) alloys. Analysis of X-ray diffraction patterns confirms that all alloys have martensitic structure at room temperature: four layered orthorhombic 4O for Ni50Mn40Sn5Co5, four layered orthorhombic 4O and seven-layered monoclinic 14...

Layered stable (multivariate) distributions and processes are defined and studied. A layered stable process combines stable trends of two different indices, one of them possibly Gaussian. More precisely, in short time, it is close to a stable process while, in long time, it approximates another stable (possibly Gaussian) process. We also investigate the absolute continuity of a layered stable p...

Organizing a software architecture into layers has been one of the earliest architectural styles ever used. Even today layered structure is a very common architectural style used in various industrial systems. However, we have observed that the usage of layered architectural style varies greatly in different contexts. This paper aims to compare the notion of software architecture layers in rese...
