Anthropogenic structures, such as wall surfaces, may change the acoustic environment for signals transmitted by animals, creating novel environments that animals must either adapt to or abandon. Animals can potentially use those structures to manipulate sound characteristics. In many anuran species, successful reproduction depends on long-range propagation(More)
The predator-prey-type ecosystem is investigated, taking into account the time-delay effect of the prey population on the predator population, as well as random variations in the birth rate of the prey and the death rate of the predators. The stochastic averaging procedure is applied to obtain the probability distributions of the predator and prey(More)
A stochastic Lotka-Volterra-type model for the interaction between the preys and the predators in a random environment is investigated. A self-competition mechanism within the prey population itself is also included. The effect of a random environment is modeled as random variations in the birth rate of the preys and the death rate of the predators. The(More)
Social monogamy is a mating strategy rarely employed by mammalian species. Laboratory studies in socially monogamous prairie voles (Microtus ochrogaster) demonstrate that oxytocin and vasopressin act within the mesolimbic dopamine pathway to facilitate pair-bond formation. Species differences in oxytocin receptor (OTR) and vasopressin 1a receptor (V1aR)(More)
Microbial diversity and community structures in acidic hot springs have been characterized by 16S rRNA gene-based diversity surveys. However, our understanding regarding the interactions among microbes, or between microbes and environmental factors, remains limited. In the present study, a metagenomic approach, followed by bioinformatics analyses, were used(More)
i-Abstract While 1080 HD is the current standard of mainstream video applications such as TV broadcasting, even higher specifications such as 4K Ultra HD have been targeted by next-generation applications. To store and transmit these mass video contents, video compression is indispensable. From MPEG-1/2/4 to H.264/AVC and HEVC etc., the continuous(More)
A segmentation method for images from Papanicolaou smears is proposed that will locate the cellular boundary based on the stability of the perimeter of the cell and will locate the nucleus based on the thresholding of a smoothed histogram. It emphasizes the selection of the thresholds for nuclear and cytoplasmic boundary tracking. The problem of touching(More)
