We study field-monitoring applications in which sensors are deployed in large numbers and the sensing process is expensive. In such applications, nodes should use the minimum possible sensing ranges to prolong the “coverage time” of the network. We investigate how to determine such minimum ranges in a distributed fashion when the nodes are location-unaware. We develop a distributed protocol (SR...

BACKGROUND Foundations and public agencies commonly fund focused initiatives for individual grantees. These discrete, stand-alone initiatives can risk failure by being carried out in isolation. Fostering synergy among grantees' initiatives is one strategy proposed for promoting the success and impact of grant programs. We evaluate an explicit strategy to build synergy within the Robert Wood Joh...

Although Cynodon dactylon (C. dactylon) is widely distributed in China, information on its genetic diversity within the germplasm pool is limited. The objective of this study was to reveal the genetic variation and relationships of 430 C. dactylon accessions collected from 22 Chinese provinces using sequence-related amplified polymorphism (SRAP) markers. Fifteen primer pairs were used to amplif...

Apricot (Prunus armeniaca L.) is an important fruit species in Turkey with high level of economic value. Sequence related amplified polymorphism (SRAP) markers were used for the first time to determine genetic diversity and relationships among Turkish and some foreign apricot cultivars. A total 87 bands were obtained from SRAP analysis and 63 of them (73%) were polymorphic. Similarity values am...

DNA size markers (ladder) are essential tools in molecular biology, genetics and biotechnology. In this study, a simple and cost-effective method for laboratory production of DNA ladders is introduced. For this purpose, different sizes of 100 to 2000 bp DNA segments were designed using PCR technique. For producing 14 different gene fragments as DNA molecular weight markers, recombinant plasmid ...

Die-back disease caused by Paecilomyces variotti is one of the most destructive diseases of pistachio in Iran. In this study, genetic diversity of Paecilomyces variotti isolates was investigated with SSR marker, using six primers pairs. Sampling was done from pistachio gardens in different geographical zones of Kerman province during summer 2013. Various fungal isolates were isolated from infec...
