The mermithid Agamermis unka, a parasite of the brown planthopper (BPH), was found in many rice paddies in Gyeongnam Province, Korea. Nematode parasitism of adult BPH varied from year to year, reaching as high as 50% in paddies not treated with an insecticide. Parasitism was lower in insecticide-treated paddies. Generally, mermithid parasitism was higher in BPH adults collected from the lower p...

This paper explains the concept of temporal convergence in the context of the time-value of knowledge. We explore epistemological aspects of knowledge/information management through notions of human cognitive awareness and mental models by which we may share situational knowledge and common intentions. We explore the temporal relationships of information (lag, reiteration, timeliness, lifetime ...

The equivalence between autonomicity and the absence of free variables is a well-known result for linear, shift-invariant and complete behaviors over a field. However, this no longer holds for a behavior that does not satisfy one of those properties. In this paper we consider linear, shift-invariant and complete behaviors over the ring Zpr and study under which conditions such behaviors are aut...

Recent advances in technology have resulted in huge increases in the flow of information to human operators in complex operational environments. Most current interfaces present the information via visual displays, thus placing great demands on the visual information processing capacity of the operator. In an effort to lessen these demands, a great deal of research has been focused on the feasib...

The paper compares properties of 3 approximate confidence intervals on the variance component corresponding to the random factor in a general case of a mixed linear model with two variance components, supposing only that more than a minimum number of observations is available. Namely, relationships between intervals suggested by Park and Burdick [6], Hartung and Knapp [5] and Thomas and Hultqui...

Simulation of human behavior in space is a powerful research method to advance our understanding of the interaction between people and their environment. It allows for both the examination and testing of models and their underlying theory of cognitive and perceptual phenomena as well as the observation of the system’s behavior. This paper outlines the use of specific spatial objects to facilita...

The interest in patterning surfaces with microand nanometer resolutions has been growing fast in recentyears, illustrating the tremendous potential of patterning techniques for both fundamental investigationsand technological applications in photonics, molecular electronics, and biosensors. Among the variouspatterning methods, liquid dispensing techniques relying on the use of m...

Background: The quantification of gene expression in tissue samples requires the use of reference genes to normalise transcript numbers between different samples. Reference gene stability may vary between different tissues, and between the same tissue in different disease states. We evaluated the stability of 9 reference genes commonly used in human gene expression studies. Realtime reverse tra...
