A New Approach to Analysing and Visualizing the Management of Corporate Innovation Projects [chapter]

Karolin Gebhardt, Andreas Riel, Tom Maes
2019 Communications in Computer and Information Science  
Innovating in a complex corporate context requires managing novelty, risk and uncertainty within an environment that strives for stability, efficiency and profitability on a daily basis. Resolving this conflict confront innovation project (IP) managers with extraordinary difficulties, which are normally addressed using classical project management methods and tools. This paper proposes an approach to analyze and capitalize the power of different project management methods within one IP in order
more » ... to increase both the probability of success and speed to success. This is achieved based on the classification of project tasks and subtasks according to their uncertainty levels with respect to the design problem and the solution. The success of work packages is assessed against pre-defined output criteria. This methodological approach is complemented by the stakeholder dimension, which takes into consideration the involved stakeholders as well as their relationships and influences in the project. The analysis of an ongoing IP at a leading global industrial player in the life science industry serves as validation platform for the presented tool set.

A useful model is one that is being (re)used. The development of a successful model does not finish with its publication. During reuse, models are being modified, i.e. expanded, corrected, and refined. Even small changes in the encoding of a model can, however, significantly affect its interpretation. Our motivation for the present study is to identify changes in models and make them transparent and traceable. Methods: We analysed 13734 models from BioModels Database and the Physiome Model

To demonstrate the impact of changes, we explored the history of a Repressilator model in BioModels Database. Results: We observed continuous updates in the majority of models. Surprisingly, even the early models are still being modified. We furthermore detected that many updates target annotations, which improves the information one can gain from models. To support the analysis of changes in model repositories we developed MoSt, an online tool for visualisations of changes in models. The scripts used to generate the data and figures for this study are available from GitHub github.com/binfalse/BiVeS-StatsGenerator and as a Docker image at hub.docker.com/r/binfalse/bives-statsgenerator. The website most.bio.informatik.uni-rostock.de provides interactive access to model versions and their evolutionary statistics. Conclusion: The reuse of models is still impeded by a lack of trust and documentation. A detailed and transparent documentation of all aspects of the model, including its provenance, will improve this situation. Knowledge about a model's provenance can avoid the repetition of mistakes that others already faced. More insights are gained into how the system evolves from initial findings to a profound understanding. We argue that it is the responsibility of the maintainers of model repositories to offer transparent model provenance to their users. Background The reuse of knowledge is key for the advancement of science [1] . Reusable computational models are provided by public repositories. Two major resources are BioModels Database [2] and the Physiome Model Repository [3] . Both repositories collect, curate, and publish models in standard formats, namely Systems Biology Markup

Acidified Nitrite Contributes to the Antitumor Effect of Cold Atmospheric Plasma on Melanoma Cells

Cold atmospheric plasma (CAP) is partially ionized gas near room temperature with previously reported antitumor effects. Despite extensive research and growing interest in this technology, active components and molecular mechanisms of CAP are not fully understood to date. We used Raman spectroscopy and colorimetric assays to determine elevated nitrite and nitrate levels after treatment with a MiniFlatPlaster CAP device. Previously, we demonstrated CAP-induced acidification. Cellular effects of

We further characterized these observations by analyzing established molecular effects of CAP treatment. A synergistic effect of nitrite and acidification was found, leading to strong cytotoxicity in melanoma cells. Interestingly, protein nitration and membrane damage were absent after treatment with acidified nitrite, thereby challenging their contribution to CAP-induced cytotoxicity. Further, phosphorylation of ERK1/2 was increased after treatment with both acidified nitrite and indirect CAP. This study characterizes the impact of acidified nitrite on melanoma cells and supports the importance of RNS during CAP treatment. Further, it defines and evaluates important molecular mechanisms that are involved in the cancer cell response to CAP.

The Hobby-Eberly Telescope (HET) is an innovative large telescope of 9.2 meter aperture, located in West Texas at the McDonald Observatory (MDO). The HET operates with a fixed segmented primary and has a tracker which moves the four-mirror corrector and prime focus instrument package to track the sidereal and non-sidereal motions of objects. A major upgrade of the HET is in progress that will increase the pupil size to 10 meters and the field of view to 22′ by replacing the corrector, tracker

In addition to supporting the existing suite of instruments, this wide field upgrade will feed a revolutionary new integral field spectrograph called VIRUS, in support of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX χ ). This paper discusses the current status of this upgrade.
