Journalists need visual interfaces that cater to the exploratory nature of their investigative activities. In this paper, we report on a four‐year design study with data journalists. The main result is netflower, a visual exploration tool that supports journalists in investigating quantitative flows in dynamic network data for story‐finding. The visual metaphor is based on Sankey diagrams and has...
Solid lubricated ball bearings can be a choice, if standard lubrication cannot be used, as for example because of surroundings like high temperature or vacuum. Law enforcements as well can be a reason for choosing such bearings. Although molybdenum disulfide (MoS 2 ) as one kind of solid lubrication for ball bearings has been known for 60 years, a universal valid lifetime prediction has not...
As important vectors of human disease, phlebotomine sand flies are of global significance to human health, transmitting several emerging and re‐emerging infectious diseases. The most devastating of the sand fly transmitted infections are the leishmaniases, causing significant mortality and morbidity in both the Old and New World. Here we present the first global transcriptome analysis of the Old World...
Analysis of gene expression data has emerged as an important approach to discover active pathways related to biological phenotypes. Previous pathway analysis methods use all genes in a pathway for linking it to a particular phenotype. Using only a subset of informative genes, however, could better classify samples. Here, we propose a two-stage machine learning approach for pathway analysis. During...
Clustering is a common step in the analysis of microarray data. Microarrays enable simultaneous high-throughput measurement of the expression level of genes. These data can be used to explore relationships between genes and can guide development of drugs and further research. A typical first step in the analysis of these data is to use an agglomerative hierarchical clustering algorithm on the correlation...
The Lattice Bhatnagar Gross and Krook (LBGK) method is widely used to solve fluid mechanical problems in engineering applications. In this work a brief introduction of the LBGK method is given and a new boundary condition is proposed for the cardiovascular domain. This enables the method to support elastic walls in two and three spatial dimensions for simulating blood flow in the abdominal aorta....
To understand and predict epidemic patterns ODEs and PDEs have been used since the beginning of the last century. But these approaches have a quite relevant shortcoming. Trying to model a multiply heterogeneous population (e.g. with individual characteristics, varying population densities) increases complexity beyond limits. To bring individual effects into epidemic models a new approach is necessary...
As recently as five years ago, the use of wireless telemetry in electric power SCADA systems was almost exclusively in the licensed radio realm. However, the scarcity of available licensed channels as well as its improved technology has made the Spread Spectrum radio an increasingly popular choice. With the install base of Spread Spectrum devices rapidly increasing, there have been a number of Urban...
