As a new software licensing model, software-as-a-service (SaaS) is gaining tremendous popularity across the globe. In this study, we investigate the competition between a new entrant and an incumbent in a SaaS market, and derive the optimal market entry strategy for the new entrant. One interesting finding is that, when its product quality is significantly lower than that of the incumbent, the ...

The suppression of protoplasmic incompatibility resulting from nonallelic gene interactions has been obtained by the coupled effect of mutations in the modA and modB genes (Bernet 1971). Due to their female sterility, modA modB strains provide an experimental tool to determine whether or not the mod and incompatibility loci are involved in a function other than protoplasmic incompatibility. Pre...

BACKGROUND Although the AB0 blood group is one of two major antigen systems of relevance for transplantation in humans, there are still conflicting data concerning the influence of AB0 incompatibility on transplant outcome. This study investigated the effect of AB0 incompatibility in recipients of bone marrow transplants from unrelated donors. DESIGN AND METHODS We retrospectively analyzed da...

In a new study, the Papaver rhoeas (poppy family) self-incompatibility system has been transferred into Arabidopsis thaliana, a distantly related plant with a very different floral structure. The simple poppy self-incompatibility system may finally make it possible to introduce this potentially valuable trait into any plant.

Self-incompatibility allows plants to recognize and reject pollen from the same plant, thereby reducing inbreeding. Although in most cases self-incompatibility is controlled by a single genetic locus, recent results show that surprisingly complex signal transduction pathways and many players are involved in pollen recognition and rejection.

R plasmids identified in Pseudomonas aeruginosa strains isolated in our laboratories were classified by their incompatibility characters by using intraspecies conjugation in P. aeruginosa. The fertility factor, FP2, was compatible with R plasmids belonging to all groups, and was classified in a new group. From these data, the plasmids examined have been placed into seven or eight incompatibilit...

since there is no detailed hospital based incident reporting system, this study was designed to evaluate the medication errors associated with infusion pumps in intensive care unit (icu). the investigation was conducted in a teaching hospital in the form of a prospective, observational study. a sample size of 43 doses administered to icu patients was chosen to enable reliable estimate of error ...

background: wolbachia  are common intracellular bacteria that infect different groups of arthropods including mos­quitoes. these bacteria modify host biology and may induce feminization, parthenogenesis, male killing and cyto­plasmic incompatibility (ci). recently wolbachia  is being nominated as a bio-agent and paratransgenic candidate to control mosquito borne diseases. methods: here we repor...

Measurement incompatibility is a distinguishing property of quantum physics and an essential resource for many information processing tasks. We introduce approach to verify the joint measurability measurements based on phase-space quasiprobability distributions. Our results, therefore, establish connection between two notions nonclassicality, namely negativity distributions measurement incompat...
