We consider the authentication problem, using the model described by Simmons. Several codes have been constructed using combinatorial designs and finite geometries. We introduce a new way of constructing authentication codes using LFSR-sequences. A central part of the construction is an encoding matrix derived from these LFSR-sequences. Necessary criteria for this matrix in order to give authentic

OBJECTIVE:: To evaluate the prognostic implication of changes in postoperative B-type natriuretic peptide (BNP) concentrations in patients undergoing cardiopulmonary bypass for cardiac surgery. DESIGN:: A retrospective analysis of prospectively collected clinical data. SETTING:: Cardiothoracic surgery and an intensive care unit (ICU) in a university hospital. PARTICIPANTS:: The present study inclu

Many embedded control systems comprise several control loops that are closed over a network of computation nodes. In such systems, complex timing behavior and communication lead to delay and jitter, which both degrade the performance of each control loop and must be considered during the controller synthesis. Also, the control performance should be taken into account during system scheduling. The

Previous work presented a real-time algorithm for detection of oscillations in PI and PID feedback control loops. This paper examines further opportunities for oscillation detection in the off-line analysis of ensembles of data from control loops. Its use with measurements from routine operations is emphasised. The paper presents operational signatures that indicate the cause of an oscillation. Ty

A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb–Pb collisions at sNN = 2.76 TeV with ALICE. This so-called Gaussian Estimator allows for the first time the study of these quantities without the influence of correlations between different flow amplitudes. The centrality depen

This book challenges earlier understandings of early modern dissertations as unimaginative academic exercises. It argues for their continuous importance in scholarly and scientific discourse, and describes the richness and diversity of their subjects and themes. The book contains a complete catalogue of the almost 20,000 Swedish dissertations defended in Uppsala, Lund and Åbo, 1600 to 1820. The ca

The 2023/2024 war in Gaza is testing Catholic–Jewish relations. It uncovers three layers of tension in the Church’s relationship with the Jewish people and the State of Israel: First, the differences in the Catholic historical interpretation of the Hamas attack and the war in Gaza in respect to the Jewish one. Second, a theological tension between Catholic teachings on Jews and Judaism and the con

As the impact of AI is difficult to assess by a single group, policymakers should prioritize societal and environmental well being and seek advice from interdisciplinary groups focusing on ethical aspects, responsibility, and transparency in the development of algorithms.

ObjectivesThis study aimed to develop and externally validate a model for predicting insufficient future liver remnant (FLR) hypertrophy after portal vein embolization (PVE) based on clinical factors and radiomics of pretreatment computed tomography (CT)Patients and methodsClinical information and CT scans of 241 consecutive patients from three Swedish centers were retrospectively collected. One c

To investigate whether coronary artery disease (CAD) burden is associated with plasma levels of the myocardial biomarkers Troponin I (TropI) and NT-proBNP in a large population-based sample using a cross-sectional design. Coronary computerized tomography (CT) angiography was performed in 25,859 subjects without a history of atherosclerotic disease from SCAPIS study (age 50-65, 52% women). TropI an

This research investigates patterns of knowledge governance practices in project-based organizations (PBOs). Five propositions about knowledge governance in PBOs were deductively and empirically tested using qualitative data from 82 interviews. The results were triangulated with those of prior studies. Results indicate that knowledge governance practices in PBOs are impacted by structural and situ
