Compact fuzzy topological spaces were first introduced by Chang [3]. o-compact fuzzy topological spaces were introduced by Gantner et al. [4]. Abd El-Monsef et al. [1] introduced the notion of e-aimost compact fuzzy topological spaces. Mashhour et al. [8] introduced the notion of bifuzzy topological spaces and defined the notion of o-compactness in those spaces. In this paper, we obtain some ne...

The objectives of this study were 1) to compare Sonoran Desert streams with other streams in terms of retention efficiency of nitrate; 2) to examine the effects of a flood on nitrate retention and to determine which factors control nitrate retention in the surface stream subsystem in Sycamore Creek, Arizona; and 3) to compare the short-term nutrient addition technique with computations based up...

Reduced blood flow contributes to tumour hypoxia and nutrient deprivation forcing cancer cells to adapt to ensure survival. In this issue of The EMBO Journal, Ye et al show that a stress response pathway including the eIF2 kinase GCN2 and its downstream target, the transcriptional activator ATF4, is critical for proliferation and survival of tumour cells after starvation for amino acids or gluc...

Letter by Lin et al Regarding Article, “Dabigatran and Thrombin Modulate Electrophysiological Characteristics of Pulmonary Vein and Left Atrium” by Chang et al To the Editor: Dr Chang et al experimentally reported that thrombin and a blood clot solution regulated pulmonary vein and left atrium arrhythmogenesis through electric and mechanical modifications by nitric oxide production and protease...

In this paper, a novel steganographic method, based on JPEG and Particle Swarm Optimization algorithm (PSO), is proposed. In order to improve the quality of stego-images, an optimal substitution matrix for transforming the secret messages is first derived by means of the PSO algorithm. The standard JPEG quantization table is also modified to contain more secret messages. The transformed message...

Mental Space Theory (Fauconnier, 1985) encompasses a wide variety of complex linguistics phenomena that are largely ignored in today’s natural language processing systems. These phenomena include conditionals (e.g. If sentences), embedded discourse, and other natural language utterances whose interpretation depends on cognitive partitioning of contextual knowledge. A unification-based formalism...
