Digital Availability of Product Information for Collaborative Engineering of Spacecraft
In this paper, we introduce a system to collect product information from
manufacturers and make it available in tools that are used for concurrent
design of spacecraft. The planning of a spacecraft needs experts from different
disciplines, like propulsion, power, and thermal. Since these different
disciplines rely on each other there is a high need for communication between
them, which is often realized by a Model-Based Systems Engineering (MBSE)
process and corresponding tools. We show by comparison that the product
information provided by manufacturers often does not match the information
needed by MBSE tools on a syntactic or semantic level. The information from
manufacturers is also currently not available in machine-readable formats.
Afterwards, we present a prototype of a system that makes product information
from manufacturers directly available in MBSE tools, in a machine-readable way.Comment: accepted at CDVE201
PubDNA Finder in a Nutshell. Searching the Life Sciences Literature with Sequences of Nucleic Acids
Biomedical researchers and clinicians working with molecular technologies in routine clinical practice often need to review the available literature to gather information regarding specific sequences of nucleic acids. This includes, for instance, finding articles related to a concrete DNA sequence, or identifying empirically-validated primer/probe sequences to evaluate the presence of different micro-organisms.
Unfortunately, these hard and time-consuming tasks often need to be manually performed by researchers themselves since no publicly available biomedical literature search engine, e.g. PubMed, PubMed Central (PMC), etc., provides the required search functionalities. In this article, we describe PubDNA Finder, a web service that enables users to perform advanced searches on PubMed Central-indexed full text articles with sequences of nucleic acid
Web Video in Numbers - An Analysis of Web-Video Metadata
Web video is often used as a source of data in various fields of study. While
specialized subsets of web video, mainly earmarked for dedicated purposes, are
often analyzed in detail, there is little information available about the
properties of web video as a whole. In this paper we present insights gained
from the analysis of the metadata associated with more than 120 million videos
harvested from two popular web video platforms, vimeo and YouTube, in 2016 and
compare their properties with the ones found in commonly used video
collections. This comparison has revealed that existing collections do not (or
no longer) properly reflect the properties of web video "in the wild".Comment: Dataset available from http://download-dbis.dmi.unibas.ch/WWIN
aFold – using polynomial uncertainty modelling for differential gene expression estimation from RNA sequencing data
Data normalization and identification of significant differential expression represent crucial steps in RNA-Seq analysis. Many available tools rely on assumptions that are often not met by real data, including the common assumption of symmetrical distribution of up- and down-regulated genes, the presence of only few differentially expressed genes and/or few outliers. Moreover, the cut-off for selecting significantly differentially expressed genes for further downstream analysis often depend on arbitrary choices
Encapsulating Ibuprofen using Beeswax Microspheres
Beeswax is extremely versatile, often used in candles, lubricants. This compound is readily available and is not very expensive. We are interested in using beeswax as a biodegradable capsule to self-encapsulate drugs like ibuprofen
Relation between the phenomenological interactions of the algebraic cluster model and the effective two--nucleon forces
We determine the phenomenological cluster--cluster interactions of the
algebraic model corresponding to the most often used effective two--nucleon
forces for the O + system.Comment: Latex with Revtex, 1 figure available on reques

Jeffreys priors for mixture estimation
While Jeffreys priors usually are well-defined for the parameters of mixtures
of distributions, they are not available in closed form. Furthermore, they
often are improper priors. Hence, they have never been used to draw inference
on the mixture parameters. We study in this paper the implementation and the
properties of Jeffreys priors in several mixture settings, show that the
associated posterior distributions most often are improper, and then propose a
noninformative alternative for the analysis of mixtures
