A platform for the development and the validation of HW IP components starting from reference software specifications
2008
Abstract Signal processing algorithms become more and more efficient as a result of the developments of new standards. It is particularly true in the field video compression. However, at each improvement in efficiency and functionality, the complexity of the algorithms is also increasing. Textual specifications, that in the past were the original form of specifications, have been substituted by reference software which became the starting point of any design flow leading to implementation. Therefore, designing an embedded application has become equivalent to port a generic software on a, possibly heterogeneous, embedded platform. Such operation is getting more and more difficult because of …
Pitfalls in Remote Team Coordination: Lessons Learned from a Case Study
2008
As companies become more and more distributed, multi-site development is becoming a norm. However along with the new opportunities, geographic distribution is proven to increase the complexity of software engineering introducing challenges for remote team communication, coordination and control. In this article we present an illustrative singe-case study with an intra-organizational intra-national context focussing on the effect of geographic distribution on team coordination practices and how this influences remote team performance. Based on our findings we conclude that a) distribution significantly influences the nature of coordination; b) remote team coordination mechanisms can't be cho…
Workshop on Competencies for the Globalization of Information Systems in Knowledge-Intensive Settings
2010
Software development has become a global task for the past decades. Outsourcing and offshoring solutions have been discussed frequently, in both research and in industry. Export is the main driver for a society’s and corresponding individual’s wealth. As more and more organizations apply outsourcing and offshoring practices, new ways have to be found to compete in this rapidly changing environment. Additionally, the digital divide is becoming a central issue, determining the relation of developed and developing countries.
Designing and Evaluating Online Language Learning Materials for Higher Education
2011
Nowadays, finding, choosing and developing or adapting materials is a very important component of education as well as a key element for the success of the whole learning process. A language teacher is also a materials developer and the materials development process should aim at ensuring that local needs and wants do not dictate decisions and that important learning principles are not forgotten. In the case of materials for Computer-Assisted Language Learning (CALL), a very thorough and pedagogically-sound set of guidelines should be followed prior to the design of the materials. Following that, a careful evaluation should take place so as to guarantee that those guidelines have been follo…

Higher Education Reforms in Finland
2019
Finland has implemented several higher education (HE) reforms over the past decades in order to make its HE system more competitive in the global educational markets. These reforms are in line with the developments in other Western higher education systems in which the transposition of principles and philosophy from the private sector into the public sector has become more common or even a norm thus reinterpreting the economic, social and cultural basis of higher education (e.g. Exworthy & Halford 1999). Furthermore, the implementation of the reforms is a response to the rapidly changing needs of the labour markets. In Finland, Bologna process was partly incorporated to be part of the react…
CORAL and COOL during the LHC long shutdown.
2013
CORAL and COOL are two software packages used by the LHC experiments for managing detector conditions and other types of data using relational database technologies. They have been developed and maintained within the LCG Persistency Framework, a common project of the CERN IT department with ATLAS, CMS and LHCb. This presentation reports on the status of CORAL and COOL at the time of CHEP2013, covering the new features and enhancements in both packages, as well as the changes and improvements in the software process infrastructure. It also reviews the usage of the software in the experiments and the outlook for ongoing and future activities during the LHC long shutdown (LS1) and beyond. CORA…
ComPWA: A common amplitude analysis framework for PANDA
2014
A large part of the physics program of the PANDA experiment at FAIR deals with the search for new conventional and exotic hadronic states like e.g. hybrids and glueballs. For many analyses PANDA will need an amplitude analysis, e.g. a partial wave analysis (PWA), to identify possible candidates and for the classification of known states. Therefore, a new, agile and efficient amplitude analysis framework ComPWA is under development. It is modularized to provide easy extension with models and formalisms as well as fitting of multiple datasets, even from different experiments. Experience from existing PWA programs was used to fix the requirements of the framework and to prevent it from restric…
In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges
2020
Flexible spikes The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein enables viral entry into host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor and is a major target for neutralizing antibodies. About 20 to 40 spikes decorate the surface of virions. Turoňová et al. now show that the spike is flexibly connected to the viral surface by three hinges that are well protected by glycosylation sites. The flexibility imparted by these hinges may explain how multiple spikes act in concert to engage onto the flat surface of a host cell. Science, this issue p. 203
In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges
2020
AbstractThe spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is required for cell entry and is the major focus for vaccine development. We combine cryo electron tomography, subtomogram averaging and molecular dynamics simulations to structurally analyze Sin situ. Compared to recombinant S, the viral S is more heavily glycosylated and occurs predominantly in a closed pre-fusion conformation. We show that the stalk domain of S contains three hinges that give the globular domain unexpected orientational freedom. We propose that the hinges allow S to scan the host cell surface, shielded from antibodies by an extensive glycan coat. The structure of native S contr…
