It is important to transmit pictures efficiently in most Web sites, especially for those users with low bandwidth connections. In this demonstration, we propose a system which progressively transmits images using a very low transmission rate (as low as 15% in some cases). The transmitted images maintain a reasonable picture quality for the users to browse images quickly. Interested readers can ...

In this paper we are investigating the long time behaviour of the solution of a mutation competition model of Lotka-Volterra’s type. Our main motivation comes from the analysis of the Lotka-Volterra’s competition system with mutation which simulates the demo-genetic dynamics of diverse virus in their host : dvi(t) dt = vi [

We present noWorkflow, an open-source tool that systematically and transparently collects provenance from Python scripts, including data about the script execution and how the script evolves over time. During the demo, we will show how noWorkflow collects and manages provenance, as well as how it supports the analysis of computational experiments. We will also encourage attendees to use noWorkf...

We present the SPIN system, a computational tool to detect linguistic and dialog structure patterns in a social interaction that reveal the underlying power relations between its participants. The SPIN system labels sentences in an interaction with their dialog acts (i.e., communicative intents), detects instances of overt display of power, and predicts social power relations between its partic...

How novel traits arise in organisms has long been a major problem in biology. Indeed, the sharpest critiques of Darwin's theory of evolution by natural selection often centered on explaining how novel body parts arose. In his response to The Origin of Species, St. George J. Mivart challenged Darwin to explain the origin of evolutionary novelties such as the mammary gland, asking if it was "conc...

BACKGROUND Instruments to assess quality of maternity care in Central and Eastern European (CEE) region are scarce, despite reports of poor doctor-patient communication, non-evidence-based care, and informal cash payments. We validated and tested an online questionnaire to study maternity care experiences among Hungarian women. METHODS Following literature review, we collated validated items ...

background: mothers’ empowerment in breast-feeding is a key motivational and psychological factor for continuous breast-feeding. therefore, this study was designed to examine the effects of family-centered educational-supportive program on mothers’ empowerment in breastfeeding. materials and methods: in this random clinical trial, pregnant women who met inclusion criteria were gradually selecte...
