Ultraviolet Superradiance from Mega-Networks of Tryptophan in Biological Architectures
Majed Chergui, Katrin Elisabeth Oberhofer
Networks of tryptophan (Trp)& horbar;an aromatic amino acid with strong fluorescence response & horbar;are ubiquitous in biological systems, forming diverse architectures in transmembrane proteins, cytoskeletal filaments, subneuronal elements, photorecepto ...
Amer Chemical Soc2024Channel-Aware 5G RAN Slicing with Customizable Schedulers
This paper focuses on 5G RAN slicing, where the 5G radio resources must be divided across slices (or enterprises) so as to achieve high spectrum efficiency, fairness and isolation across slices, and the ability for each slice to customize how the radio res ...
USENIX ASSOC2023P3LI5: Practical and confidEntial Lawful Interception on the 5G core
Apostolos Pyrgelis, Francesco Intoci
Lawful Interception (LI) is a legal obligation of Communication Service Providers (CSPs) to provide interception capabilities to Law Enforcement Agencies (LEAs) in order to gain insightful data from network communications for criminal proceedings, e.g., ne ...
New York2023impresso Text Reuse at Scale. An interface for the exploration of text reuse data in semantically enriched historical newspapers
Maud Ehrmann, Matteo Romanello
Text Reuse reveals meaningful reiterations of text in large corpora. Humanities researchers use text reuse to study, e.g., the posterior reception of influential texts or to reveal evolving publication practices of historical media. This research is often ...
2023Associations between in vitro, in vivo and in silico cell classes in mouse primary visual cortex
Werner Alfons Hilda Van Geit, Anatoly Buchin
The brain consists of many cell classes yet in vivo electrophysiology recordings are typically unable to identify and monitor their activity in the behaving animal. Here, we employed a systematic approach to link cellular, multi-modal in vitro properties f ...
2023Low-Cost Multibeam Millimeter-Wave Array Antennas for 5G Mobile Applications
This paper presents a low-cost, compact, multibeam planar antenna system with a wide ±138∘ beam coverage angle at 28 GHz for 5G applications. The proposed microstrip based design includes two branch-line couplers and a Butler matrix with 2×10 and 4×10 seri ...
2022Increasing Cellular Network Energy Efficiency for Railway Corridors
Andreas Peter Burg, Adrian Schumacher, Ruben Merz
Modern trains act as Faraday cages making it challenging to provide high cellular data capacities to passengers. A solution is the deployment of linear cells along railway tracks, forming a cellular corridor. To provide a sufficiently high data capacity, m ...
IEEE2022Cellular Fronthauling for Data Capacity Increase in Underserved Spaces
The increase in wireless data traffic continues and is a product of several factors. First, new technologies and capabilities enable new use cases for which new products emerge. Then, with the growing user adoption over time, the data traffic is further in ...
EPFL2022Beam Selection and Tracking for Amplify-and-Forward Repeaters
Andreas Peter Burg, Adrian Schumacher, Ruben Merz
Mobile network operators constantly have to upgrade their cellular network to satisfy the public's hunger for increasing data capacity. However, regulatory limits regarding allowed electromagnetic field strength on existing cell sites often limit or preven ...
IEEE2022Opacité et transparence dans le design d'un dispositif de surveillance urbain : le cas de l'IMSI catcher
This thesis assesses the surveillance operated on the mobile phone network by governmental actors (intelligence agencies, police, army) and the relationship between monitored spaces and their users. Indeed, some new surveillance devices used by intelligenc ...
