We investigate style accommodation in online discussions, in particular its interplay with content agreement and disagreement. Using a new model for measuring style accommodation, we find that speakers coordinate on style more noticeably if they disagree than if they agree, especially if they want to establish rapport and possibly persuade their interlocutors.

An (n)completely separating system C ((n)CSS) is a collection of blocks of [n] = {1, . . . , n} such that for all distinct a, b ∈ [n] there are blocks A,B ∈ C with a ∈ A \B and b ∈ B \A. An (n)CSS is minimal if it contains the minimum possible number of blocks for a CSS on [n]. The number of non-isomorphic minimal (n)CSSs is determined for 11 ≤ n ≤ 35. This also provides an enumeration of a nat...

The symbolic representation of the physical structure of living organisms needs an ontologically well-founded and logically sound approach so that formal reasoning can adequately be supported. We describe a set of canonical relations and attributes necessary for the description of biological structures. Based on these epistemological primitives, we sketch how a broad range of organisms can be r...

Graphene oxide (GO) is a promising precursor to produce graphene-family nanomaterials for various applications. Their potential health and environmental impacts need a good understanding of their cellular interactions. Many factors may influence their biological interactions with cells, and the lateral dimension of GO sheets is one of the most relevant material properties. In this study, a mode...

In some applications such as morphing technology, high strain and anisotropic behavior are considered a good advantage. The corrugated composite sheets due to their special geometries have a potential of high deflection under axial loading. In this research, to investigate the strain and anisotropic behavior of corrugated composite sheets some glass/epoxy samples with Quasi-sinusoidal, trapezoi...

Background and Aim: Currently in most hospitals medical mission and medical  documents secession don't be notified  about any disciplines in the framework of documenting medical data and in parallel the document makers will be overshadowed by non-executing these principles qualitatively and quantitatively(1). Materials and Methods: The above study is a sectional one that describes the situatio...

Chitosan produced by the deacetylation of chitin is a cationic polymer with antimicrobial properties. In this study, we demonstrate the improvement of chitosan properties by nanofibrillation. Nanofiber sheets were prepared from nanofibrillated chitosan under neutral conditions. The Young's modulus and tensile strength of the chitosan NF sheets were higher than those of the chitosan sheets prepa...

The endoplasmic reticulum (ER) consists of the nuclear envelope and a peripheral network of tubules and membrane sheets. The tubules are shaped by the curvature-stabilizing proteins reticulons and DP1/Yop1p, but how the sheets are formed is unclear. Here, we identify several sheet-enriched membrane proteins in the mammalian ER, including proteins that translocate and modify newly synthesized po...

this paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. after a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. using doublet mechanics, the relation between natural f...

Between the sheets: Sodium-ion batteries are an attractive, low-cost alternative to lithium-ion batteries. Nitrogen-doped porous carbon sheets are prepared by chemical activation of polypyrrole-functionalized graphene sheets. When using the sheets as anode material in sodium-ion batteries, their unique compositional and structural features result in high reversible capacity, good cycling stabil...
