Timed Automata Semantics for Visual e-Contracts

open access: yes, 2011
C-O Diagrams have been introduced as a means to have a more visual representation of electronic contracts, where it is possible to represent the obligations, permissions and prohibitions of the different signatories, as well as what are the penalties in ...

Minimal Reduction in Patellar Height Following Anteromedializing Tibial Tubercle Osteotomy With Medial Patellofemoral Ligament Reconstruction

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To assess whether anteromedializing tibial tubercle osteotomy (AMZ TTO) results in reduction in patellar height when performed alongside medial patellofemoral ligament reconstruction (MPFLR) for the treatment of patellar instability. Methods We performed a retrospective review of patients who underwent AMZ TTO with MPFLR between 2017 and 2024 ...

Multicarrier systems and filter banks [PDF]

open access: yesAdvances in Radio Science, 2006
Multicarrier systems, especially orthogonal frequency division multiplex (OFDM), are already established in a lot of current communications standards. Moreover, they are very prominent candidates for future systems in mobile communications.

Identifying Systemic Lupus Erythematosus From Serum Proteomic Profiles Using Machine Learning and Genetic Risk Stratification

open access: yesArthritis &Rheumatology, EarlyView.
Objective Proteome‐wide risk models for lupus remain underexplored. We developed classification models to identify lupus from serum proteomic profiles. Methods Patients with lupus and individuals with other autoimmune diseases in the UK Biobank were included.

Higher complement C4 gene copy number constitutes a shared genetic risk factor for giant cell arteritis and IgA vasculitis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Performance Analysis of Multicarrier Systems in the Presence of Smooth Nonlinearity

open access: yesEURASIP Journal on Wireless Communications and Networking, 2004
Most of the performance studies devoted to the analysis of multicarrier systems in the presence of nonlinear distortion assume that the multicarrier signal can be modeled as a random Gaussian process regardless of modulation format, guard interval ...

Sampling and Timing: A Task for the Environmetal Process [PDF]

open access: yes, 2003
Sampling and timing is considered a responsibility of the environment of controller software. In this paper we will illustrate a concept whereby an environmental process and multi-way events play an important role in applying timing for untimed CSP ...
