CERN operates complex underground facilities, with the Large Hadron Collider (LHC) posing unique fire detection challenges due to ionising radiation, long tunnel spans, and variable ventilation. To address the limitations of aspirating smoke detectors in both current and future CERN facilities, Distributed Temperature Sensing (DTS) systems using radiation-resistant optical fibers are being exp

The world is constantly changing, and business strategies are changing with it. Companies are offering new delivery options and technologies for customers globally when doing purchases. IKEA, a global furniture retailer, is expanding their touchpoints by opening retail stores in city centre locations in order to become more accessible. The ways customers travel in urban areas are more varied incl
The function of porcine left lung allografts was studied after perfusion with (150 mL/kg) and storage for 12 hours in a 4 degrees to 6 degrees C low-potassium-dextran solution (Perfadex; Kabi Pharmacia AB, Uppsala, Sweden). After a left lung transplantation, an artificial lung in the form of venoarterial extracorporeal membrane oxygenation was established. The artificial lung has a "biological" he
The European Energy production system is in transition towards renewable energy sources (RES). Concrete targets have been set through the European Union “Energy Roadmap 2050”. The transition has started by national states but concrete action towards the targets has been mainly taken up at a local level. In this context, this research work aims at exploring how can a community trigger and drive an
Context. The Gaia satellite will observe about one billion stars and other point-like sources. The astrometric core solution will determine the astrometric parameters (position, parallax, and proper motion) for a subset of these sources, using a global solution approach which must also include a large number of parameters for the satellite attitude and optical instrument. The accurate and efficien
Modern microbial and ecosystem sciences require diverse interdisciplinary teams that are often challenged in “speaking” to one another due to different languages and data product types. Here we introduce the IsoGenie Database (IsoGenieDB; https://isogenie-db.asc.Ohio-state.edu/), a de novo developed data management and exploration platform, as a solution to this challenge of accurately representin
Using a dislocation simulation approach, the basic equation for a crack perpendicular to a bimaterial interface is formulated in this paper. A novel expansion method is proposed for solving the problem. The complete solution for the problem, including the T stress ahead of the crack tip and the stress intensity factors are presented. The stress field characteristics are analyzed in detail. It is f
Although based on decentralized principles, the World Wide Web has become highly centralized with a few multinational tech corporations hosting and providing all of the services most people use the internet for. This has led to the unproportionate power some companies hold over the world’s people and has wide consequences, not least is reduced integrity. As a response to this development, decentra
