Seed production and population density decline approaching the range‐edge of Cirsium species

New Phytologist, 2003
• Patterns in population density and abundance, community composition, seed production and morphological traits were assessed across the UK geographical range of Cirsium acaule, Cirsium heterophyllum and Cirsium arvense based on the expectation that

The influence of cellular seeding density in the microencapsulation of hybridoma cells

Journal of Biomaterials Science, Polymer Edition, 2005
The aim of this study was to assess the influence of different seeding densities on the function of hybridoma cells (clone 1B5, IgG 2alpha) producing an anti-angiogenic monoclonal antibody (mAb), microencapsulated using a high-voltage electrostatic field.

A Density-Based Seed-Centric Community Detection Algorithm

2016 13th Web Information Systems and Applications Conference (WISA), 2016
Although many different community detection algorithms have been proposed to detect community structures in complex networks, how to effectively detect community structures is still a great challenge. Seed-centric methods is one of the most effective solutions for community detection.

Robust partitional clustering by outlier and density insensitive seeding

Pattern Recognition Letters, 2009
The leading partitional clustering technique, k-means, is one of the most computationally efficient clustering methods. However, it produces a local optimal solution that strongly depends on its initial seeds. Bad initial seeds can also cause the splitting or merging of natural clusters even if the clusters are well separated. In this paper, we propose,

Principles for Microwave Moisture and Density Measurement in Grain and Seed

Journal of Microwave Power and Electromagnetic Energy, 2004
The importance of cereal grain moisture content in determining time of harvest and in preserving grain quality is described. Techniques for moisture measurement, including electronic moisture meters, are also discussed briefly, and the need for better moisture sensing techniques for modern agricultural on-line moisture monitoring is described ...

Seed quality in carrots: the effects of seed crop plant density, harvest date and seed grading on seed and seedling variability

Journal of Horticultural Science, 1983
SummaryCarrot seeds (Chantenay types) harvested 44–61 days after anthesis (early harvest) had higher coefficients of variation (CVs) of embryo length and subsequent seedling weight than those of seeds harvested 70–92 days after anthesis (late harvest). Seed grading after harvesting the seed crop reduced the CVs of some of the early harvested seed crops.

Density-dependent germination response by seeds of desert annuals

Oecologia, 1980
Field observations and experiments indicate that the presence of seedlings at high densities inhibits subsequent germination of desert annuals. Since plants growing at high densities face severe competition for limited resources, this response by seeds is interpreted as an adaptation to avoid an unfavorable competitive climate where growth and ...

String-Seeded Spirals: Origin of Rotation and the Density of the Halo

Physical Review Letters, 1986
Galactic halos seeded by loops of string in a universe dominated by dark matter fall into two categories: (1) Non-self-intersecting loops precipitate nearly spherically symmetric collapse and lead to a halo with low angular momentum J and a density profile rho--r/sup -9/4/. (2) Progeny of a self-intersecting primary loop recollapse into a single object
