Preferential attachment in the growth of social networks: the case of Wikipedia [PDF]

, 2006
We present an analysis of the statistical properties and growth of the free on-line encyclopedia Wikipedia. By describing topics by vertices and hyperlinks between them as edges, we can represent this encyclopedia as a directed graph.

The Smith Cloud and its dark matter halo: Survival of a Galactic disc passage [PDF]

, 2014
The current velocity of the Smith Cloud indicates that it has undergone at least one passage of the Galactic disc. Using hydrodynamic simulations we examine the present day structure of the Smith Cloud.

Sliding not sloshing in Abell 3744: the influence of radio galaxies NGC 7018 and 7016 on cluster gas [PDF]

, 2013
We present new X-ray (Chandra) and radio (JVLA) observations of the nearby cluster Abell 3744. It hosts two prominent radio galaxies with powers in the range critical for radio-mode feedback.

Transcriptome analysis unveils a potential novel role of VvAP1 in regulating the developmental fate of primordia in grapevine

Fruit Research
The grapevine shoot meristem contains undifferentiated primordia known as anlagen, which can develop into either inflorescences or tendrils depending on vine age, growth status, hormone balance, and other factors.

Viscous Withdrawal of Miscible Liquid Layers

, 2007
In viscous withdrawal, a converging flow imposed in an upper layer of viscous liquid entrains liquid from a lower, stably stratified layer. Using the idea that a thin tendril is entrained by a local straining flow, we propose a scaling law for the volume

Giant strongly connected component of directed networks

, 2001
We describe how to calculate the sizes of all giant connected components of a directed graph, including the {\em strongly} connected one. Just to the class of directed networks, in particular, belongs the World Wide Web.

A defined medium to investigate sliding motility in a Bacillus subtilis flagella-less mutant

BMC Microbiology, 2006
Background We have recently shown that undomesticated strains of Bacillus subtilis can extensively colonize the surfaces of rich, semi-solid media, by a flagellum-independent mechanism and suggested that sliding motility is responsible for surface ...

Tendrils of Smilax [PDF]

Botanical Gazette, 1920
In this paper the conflicting views hitherto held regarding the nature of the tendrils of Smilax are briefly considered, and it is concluded, on grounds of anatomy and external morphology, that these tendrils are equivalent to the petiole in morphological value, and have arisen through chorisis or dedoublement of that organ.

Tendril Perversion in Intrinsically Curved Rods

Journal of Nonlinear Science, 2002
This article deals with an inversion of handedness, or chirality, of a thin elastic rod with a certain structure along its axial coordinate, which the authors call intrinsic curvature. The inversion is known as a perversion phenomena, e.g., of a tendril.
