Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

The distribution of nematodes was studied in rice fields in Guilan province, Iran, from 2014 to 2016. Nematode biodiversity of 250 soil and root samples was examined. Thirty nematode species were identified morphologically, including plant parasites, microbivores and mycetophagous and predator species. Molecular techniques were also used for further identification of three plant parasitic speci...

A new genus Sireuma is described to accommodate a new species, S. nobile, from a cave in Portugal. The unique features of the male gonopods and the absence of a postvulvar organ support the creation of a new genus. The new species is illustrated with scanning electron micrographs and diagrammatic drawings. Differences vis-à-vis its relatives are discussed, and information on the environment in ...

Spiroplasma kunkelii causes corn stunt disease of Zea mays L. in the Americas. Here, we report the nucleotide sequence of the 1,463,926-bp circular chromosome and four plasmids of strain CR2-3x. This information will facilitate studies of Spiroplasma pathogenicity and evolutionary adaptations to transkingdom parasitism in plants and insect vectors.

In the part of the Loire River recently colonized by Eurasian beavers, we compared habitat characteristics among sites with lodges, sites with cut trees and sites without beaver. The absence of sandbank and canopy cover (by 10-15-m tall trees, by tall Salicaceae, and by bushy Salicaceae) appeared as good predictors for lodge settling. Based on this model, the number of proper lodge sites was es...

We investigate how novel English-derived words (anglicisms) are used in a Germanlanguage Internet hip hop forum, and what factors contribute to their uptake.

The IEEE 802.15.4 standard allows for the deployment of cost-effective and energy-efficient multi-hop networks. This document features an in-depth presentation of an analytical model for assessing the performance of such networks. It considers a generic, static topology with Poisson distributed datacollection as well as data-dissemination traffic. The unslotted CSMA/CA MAC layer of IEEE 802.15....

This paper introduces new ways to establish data link level forwarding for IPv6 packets on ATM links. The designed method is merged into to the core of IPv6 protocol. This improves the performance compared to the other traffic-based IP over ATM protocols.
