Sequential Detection and Estimation of Multipath Channel Parameters Using Belief Propagation

This paper proposes a belief propagation (BP)-based algorithm for sequential detection and estimation of multipath component (MPC) parameters based on radio signals. Under dynamic channel conditions with moving transmitter/receiver, the number of MPCs, the MPC dispersion parameters, and the number of false alarm contributions are unknown and time-varying. We develop a Bayesian model for sequential

Postoperative Atrial Fibrillation in Adults with Obstructive Sleep Apnea Undergoing Coronary Artery Bypass Grafting in the RICCADSA Cohort

Postoperative atrial fibrillation (POAF) occurs in 20–50% of patients with coronary artery disease (CAD) after coronary artery bypass grafting (CABG). Obstructive sleep apnea (OSA) is also common in adults with CAD, and may contribute to POAF as well to the reoccurrence of AF in patients at long-term. In the current secondary analysis of the Randomized Intervention with Continuous Positive Airway

The effect of metamorphism on the aggregate properties of gabbroic rocks

Granitic rocks are durable materials sought after for the production of road and railroad aggregates. Granitic bedrock commonly, however, includes gabbroic components, which may enhance or decrease the aggregate performance. This study evaluates the variation in resistance to fragmentation (Los Angeles value, LA) and wear/abrasion (micro-Deval value, MDE) for the fraction 10/14 mm of gabbro in dif

HIV-2 Neutralization Sensitivity in Relation to Co-Receptor Entry Pathways and Env Motifs

HIV-2, compared to HIV-1, elicits potent and broadly neutralizing antibodies, and uses a broad range of co-receptors. However, both sensitivity to neutralization and breadth of co-receptor use varies between HIV-2 isolates, and the molecular background is still not fully understood. Thus, in the current study, we have deciphered relationships between HIV-2 neutralization sensitivity, co-receptor u

Review: Representing Islam: Hip-Hop of the September 11 Generation

The book Representing Islam: Hip-Hop of the September 11 Generation (2020) by Kamaludeen Mohmed Nasir explores the entangled relationship between Islam and hip-hop. The book centers around Muslim hip-hop artists affected by the war on terror and the long-term consequences of the 9/11 attacks; increased surveillance, a securitization of Islam, and an amplified islamophobia, not only in the United S

Benchmark Study of Redox Potential Calculations for Iron-Sulfur Clusters in Proteins

Redox potentials have been calculated for 12 different iron-sulfur sites of 6 different types with 1-4 iron ions. Structures were optimized with combined quantum mechanical and molecular mechanical (QM/MM) methods, and the redox potentials were calculated using the QM/MM energies, single-point QM methods in a continuum solvent or by QM/MM thermodynamic cycle perturbations. We show that the best re

Natural separation of two primordial planetary reservoirs in an expanding solar protoplanetary disk

Meteorites display an isotopic composition dichotomy between noncarbonaceous (NC) and carbonaceous (CC) groups, indicating that planetesimal formation in the solar protoplanetary disk occurred in two distinct reservoirs. The prevailing view is that a rapidly formed Jupiter acted as a barrier between these reservoirs. We show a fundamental inconsistency in this model: If Jupiter is an efficient blo

”’Man måste verkligen ändra i läroböckerna för att få en ändring i samhället’. Kön och könsidentitet i skolan”

Denna text beskriver hur normer kring kön påverkar elever som är trans på olika sätt, alltså till exempel killar med transerfarenhet, ickebinära och transtjejer. Texten bygger på en intervjustudie med 13 unga och unga vuxna som berättar om sina erfarenheter av att vara trans på olika sätt i skolan. Det är den första studien av sitt slag i en svensk kontext. Deltagarna i studien var mellan 16 och 2

The attractions of Salafi-jihadism as a gendered counterculture: Propaganda narratives from the Swedish online “sisters in deen”

By conducting an online ethnographic study of the unofficial propaganda narratives posted on Facebook by Swedish women affiliated with the Salafi-jihadi movement, Dr Henriette Frees Esholdt explores and analyses the female-specific attractions of Salafi-jihadism within a Swedish context in Chapter 4. In addition to the promotion of Sharia law, gender segregation, as well as the maintenance of a pa
