This paper presents a new semi-competitive learning paradigm named Competitive and Cooperative Learning (CCL), in which seed points not only compete each other for updating to adapt to an input each time, but also dynamically cooperate to achieve the learning task. This competitive and cooperative mechanism can automatically merge those extra seed points, meanwhile making the seed points gradua...

Chitosan was modified with sodium hydroxide and polymerized in water with plant growth regulators, microfertilizer and other additives to give a novel environmentally friendly seed coating agent for rice. The results showed the seed coating agent has obvious biological effect through the germination test, bacteriostasis test, toxicological security test and field experiment. Compared with the t...

To improve the search performance of retrieval methods using cocitation linkages, this study proposes a technique to enlarge a co-citation network by incorporating satellite documents. This technique specifies satellite documents via full-text searches for terms obtained from documents having cocitation linkages with a seed document; the appropriateness of each co-citation linkage is checked by...

The production of morphologically different seeds or fruits by the same individual plant is known as seed heteromorphism. Such variation is expected to be selected for in disturbance-prone environments to allow germination into inherently variable regeneration niches. However, there are few demonstrations that heteromorphic seed characteristics should be favored by selection or how they may be ...

MOTIVATION Similarity clustering of next-generation sequences (NGS) is an important computational problem to study the population sizes of DNA/RNA molecules and to reduce the redundancies in NGS data. Currently, most sequence clustering algorithms are limited by their speed and scalability, and thus cannot handle data with tens of millions of reads. RESULTS Here, we introduce SEED-an efficien...

In this paper we report on advances regarding our approach to porting an automatic speech recognition system to a new target task. In case there is not enough acoustic data available to allow for thorough estimation of HMM parameters it is impossible to train an appropriate model. The basic idea to overcome this problem is to create a task independent seed model that can cope with all tasks equ...

The effects of seed source and seed size on germination and field performance were studied in five grasses. Greater seed weights were associated with better germination in Yorkshire fog, cocksfoot and timothy but not significantly so for Chewings fescue and browntop. In cocksfoot, Chewings fescue and timothy, higher seed weights were found in samples collected at altitudes above those generally...

1 We examined how seed size and seedling growth rate influence recruitment success of neotropical pioneer species. We investigated the soil seed bank, and followed seedlings from emergence and establishment to the sapling stage in artificially created gaps in secondary forest on the Barro Colorado Nature Monument, Panamá. 2 To simulate microsite variation within gaps, litter addition/removal an...
