the present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. the behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. boundedness and dissipativeness of the system are e...

Hybrid speciation has played a significant role in the evolution of angiosperms at the polyploid level. However, relatively little is known about the importance of hybrid speciation at the diploid level. Two species of Penstemon have been proposed as diploid hybrid derivatives based on morphological data, artificial crossing studies, and pollinator behavior observations: Penstemon spectabilis (...

One of the key innovations introduced by web mashups into the integration landscape (basically focusing on data and application integration) is integration at the UI layer. Yet, despite several years of mashup research, no commonly agreed on component technology for UIs has emerged so far. We believe W3C’s widgets are a good starting point for componentizing UIs and a good candidate for reachin...

When gene regulatory networks diverge between species, their dysfunctional expression in inter-species hybrid individuals can create genetic incompatibilities that generate the developmental defects responsible for intrinsic post-zygotic reproductive isolation. Both cis - and trans -acting divergence be hastened by directional selection through adaptation, sexual selection, inter-sexual conflic...

The wireless systems entered a phase characterized by the integration of the existing platforms into hybrid access wireless IP architectures. The requests of the real time applications ran in heterogeneous environments need the presence of a mechanism for resource negotiation and management. The paper suggests the design and implementation of an inter-domain QoS mechanism in a hybrid access wir...

We test the Consensual Assessment Technique on recent digital poetry, using graduate students in Experimental Digital Media as judges. Our judges display good interrater agreement for the best and worst poems, but disagree on others. The CAT by itself may not be suitable for use on digital poetry; however, the behavior of quasi-expert judges when attempting this task gives us clues towards evid...

One hundred and three Aspergillus isolates belonging to 12 species including: A. alliaceus, A. candidus, A. carneus, A. flavus, A. fumigatus, A. niger var. niger, A. niger var. awamori, A. niveus, A. ochraceous, A. sydowii, A. terreus, A. ustus,and A. versicolor based on morphological characters were obtained from various sources. 

The application of heterosis (hybrid vigor) has brought great success to plant breeding, particularly of hybrid rice, achieving significant yield increases. Attempts to explore the heterosis of inter-subspecific hybrids between indica and japonica rice, which result in even greater yield increases, have greatly increased in the past decades. However, because of the reduced seed setting rate in ...
