Charged lepton induced one kaon production off the nucleon
2013
We study single kaon production off the nucleon induced by electrons (positrons) i.e., e(-) (e(+)) + N -> v(e) ((v) over bar (e)) + (K) over bar (K) + N' at low energies. The possibility of observing these processes with the high luminosity beams available at TJNAF and Mainz is discussed, taking into account that the strangeness conserving electromagnetic reactions have a higher energy threshold for (K) over bar (K) production. The calculations are done using a microscopic model that starts from the SU(3) chiral Lagrangians and includes background terms and the resonant mechanisms associated to the lowest lying resonance Sigma*(1385)
Low-diffusion Xe-He gas mixtures for rare-event detection: electroluminescence yield
2020
[EN] High pressure xenon Time Projection Chambers (TPC) based on secondary scintillation (electroluminescence) signal amplification are being proposed for rare event detection such as directional dark matter, double electron capture and double beta decay detection. The discrimination of the rare event through the topological signature of primary ionisation trails is a major asset for this type of TPC when compared to single liquid or double-phase TPCs, limited mainly by the high electron diffusion in pure xenon. Helium admixtures with xenon can be an attractive solution to reduce the electron diffu- sion significantly, improving the discrimination efficiency of these optical TPCs. We have m…
γ-ray linear polarization measurements and(g9/2)−3neutron alignment in91Ru
2013
The authors would like to thank the operators of the GANIL cyclotrons for providing the 36Ar beam. We would also like to thank the EXOGAM Collaboration for use of the clover Ge detector array, the DIAMANT Collaboration for use of the charged particle detector system, and the European gamma-ray Spectroscopy Pool for use of the neutron detector system.

Smarter Open Government Data for Society 5.0: Are Your Open Data Smart Enough?
2021
Nowadays, governments launch open government data (OGD) portals that provide data that can be accessed and used by everyone for their own needs. Although the potential economic value of open (government) data is assessed in millions and billions, not all open data are reused. Moreover, the open (government) data initiative as well as users’ intent for open (government) data are changing continuously and today, in line with IoT and smart city trends, real-time data and sensor-generated data have higher interest for users. These “smarter” open (government) data are also considered to be one of the crucial drivers for the sustainable economy, and might have an impact on information and communi…

Development of a living organoid biobank derived from colorectal cancer patients: Towards personalized medicine
2019
Abstract Background Organoids are 3D in vitroprimary culture of great interest for translational research representing an efficient and reproducible cancer model. The aim of this project is to generate a biobank of colorectal cancer (CRC) patients derived organoids (PDOs) that could be used to analyze molecular characteristics and to test different treatments as well as to study the underlying molecular causes of cancer and treatment resistance. Methods Primary or metastatic CRC tissues have been obtained from patients who underwent surgery. Tissue has been washed and incubated with antibiotics. After mechanical and enzymatic digestion, free cells have been seeded in Matrigel with proper me…
Just in case, just in time, or just don't bother? Assessment of one-shot library instruction with follow-up workshops
2015
Published version from the journal: LIBER Quarterly. Available from the publisher at: http://liber.library.uu.nl/index.php/lq/article/view/URN%3ANBN%3ANL%3AUI%3A10-1-116866 This article examines if the timing of library instruction courses is an important part of how students experience library instruction as a means of developing information literacy skills. Two student groups, belonging to different academic subjects, have received the same training and the same assessment questionnaire afterwards. One of the groups was in the middle of writing their student thesis as a part of their final year of their bachelor degree work, the other group consisted of different subjects within the human…

In this research paper, social media marketing activities of social media accounts from German business are analyzed for the social networks Facebook, Twitter, Instagram, Xing and LinkedIn. As research objects were the context of the interaction, the used and targeted social network functionalities and the behavior of the companies selected. The selection of social media accounts for the research included companies which are currently member from the stock market indices DAX and MDAX, additional online and offline retail business, successful German sports clubs, celebrities and others businesses. Also and to be sure to evaluate high-class social media marketing, the German social media awar…
Author Rights vs Self-Archiving in Spanish Scientific Journals
2013
AbstractThe paper analyzes publishers’ copyright policies and self-archiving conditions of Spanish scientific journals. Data are extracted from the directory DULCINEA that contains information of 1318 Spanish journals, of which 775 (61%) allow some form of self-archiving to be about 60% of the post-print version and allowing them 87% of the deposit of the version of record. In 72% of journals the deposit can be performed immediately after publication and in 16% after article acceptance. 72% of the journals are freely available without charge to the user this figure raises up to 86% if free access after an embargo is considered. Only 18% of the journals use Creative Commons licenses. The ado…
Timeliness of Open Data in Open Government Data Portals Through Pandemic-related Data: a long data way from the publisher to the user
2020
The paper addresses the “timeliness” of data in open government data (OGD) portals. It is one of the primary principles of open data, which is considered to be a success factor, while at the same time it is one 0f the biggest barriers that can disrupt users trust in data and even the desire to use the entire open data portal. However, assessing this aspect is a very difficult task that, in most cases, becomes an impossible for open data users. There is therefore a lack of comparative studies on the timeliness of data of different national open data portals. Unfortunately, 2020 gave the opportunity to find out this. It became easy enough to compare how long is the data path from the data hol…
