We propose and analyze a novel scheme based on LDPC codes for quantitative group testing. The key underlying idea is to augment the bipartite graph by introducing hidden non-binary variables to strengthen the message-passing decoder. This is achieved by grouping items into bundles of size q within the test matrix, while keeping the testing procedure unaffected. The decoder, inspired by some works

Many algorithms in computer graphics make use of acceleration structures such as Bounding Volume Hierarchies (BVHs) to speed up performance critical tasks, such as collision detection or ray-tracing. However, while the typical algorithms for constructing BVHs are relatively simple, actually implementing them for performance critical systems is still challenging. Further, to construct them as quick

Parallel-elastic joints can improve the efficiency and strength of robots by assisting the actuators with additional torques. For these benefits to be realized, a spring needs to be carefully designed. However, designing robots is an iterative and tedious process, often relying on intuition and heuristics. We introduce a design optimization framework that allows us to co-optimize a parallel elasti

IntroductionGlobal water scarcity necessitates innovative approaches to water treatment. Membrane technology has emerged as a key solution, demonstrating its effectiveness across a range of applications, from seawater desalination using reverse osmosis to wastewater treatment with membrane bioreactors. This presentation will introduce three novel water treatment concepts based on membrane technolo

Objective: To evaluate (1) the frequency of aquaporin-4 antibody (AQP4-ab)-seropositive cases among patients treated with natalizumab (NAT) and previously diagnosed with MS (MSNAT) in a nationwide cohort, (2) the clinical course of NAT-treated AQP4-ab-seropositive neuromyelitis optica spectrum disorder (NMOSD) patients (NMONAT), (3) AQP4-ab titers in NMONAT and AQP4-ab-seropositive NMOSD treated w

The Centre has since 2006 organised a range of film festivals on different topics, including the situation of youth in East and South-East Asia, urban transformations, and memory and trauma. We have also organised many individual film screenings and discussions, sometimes with invited film directors. The screening of documentary films has been integrated with teaching in many of our courses. The p

LUNARC was formed as a collaboration between groups in Theoretical Chemistry, Physical Chemistry 2, and Structural Mechanics in 1986. The founding members were later joined by Theoretical Physics and in 1996, LUNARC was transformed into a centre for scientific and technical computing at Lund University. Together with five other centres, LUNARC became a part of the Swedish National Infrastructure f

Since the end of the cold war issues concerning civil preparedness at the municipal level has been slumbering in Sweden. During WWII and the cold war Sweden had an extensive civil preparedness at all political levels. With the absence of the threat of war the civil preparedness in Sweden faded away. Now in a state of awakening the municipalities are starting to heighten the level of civil prepared

John Cassian’s writings reveal an extensive education. In his works, he reflects on his own education, such as a case of mnemotechnical distraction, and also provides education for his readers. But it is also clear that he employs his own rhetorical education by using conscious rhetorical strategies. This third aspect is the focus of this article. In Late Antique higher education, the chreia was o
