Utilization of real‐world data in assessing treatment effectiveness for diffuse large B‐cell lymphoma

open access: yesAmerican Journal of Hematology, Volume 98, Issue 1, Page 180-192, January 2023., 2023
Abstract Direct comparisons of the effectiveness of the numerous novel therapies in the diffuse large B‐cell lymphoma (DLBCL) treatment landscape in a range of head‐to‐head randomized phase 3 trials would be time‐consuming and costly. Comparative effectiveness studies using real‐world data (RWD) represent a complementary approach.

An anti-jamming system for GNSS timing applications

open access: yes2018 European Frequency and Time Forum (EFTF), 2018
Radio-Frequency Interference (RFI) and jamming are increasing problems for timing applications based on Global Navigation Satellite Systems (GNSS). FENIX-lite is a real-time pre-correlation anti-jamming system designed to provide increased resilience against RFI/jamming in critical GNSS-enabled applications.

Anti-jamming timing channels for wireless networks [PDF]

open access: yesProceedings of the first ACM conference on Wireless network security, 2008
Wireless communication is susceptible to radio interference, which prevents the reception of communications. Although evasion strategies have been proposed, such strategies are costly or ineffective against broadband jammers. In this paper, we explore an alternative to evasion strategies that involves the establishment of a timing channel that exists ...

Anti-jamming performance of cognitive radio networks [PDF]

open access: yes2011 45th Annual Conference on Information Sciences and Systems, 2011
In this paper, we study both the jamming capability of the cognitive-radio-based jammers and the anti-jamming capability of the cognitive radio networks. We first setup the models of cognitive-radio-based jammers and the cognitive radio network transmissions.
