Spherical motion is a special case of camera motion where the camera moves on the imaginary surface of a sphere with the optical axis normal to the surface. Common sources of spherical motion are a person capturing a stereo panorama with a phone held in an outstretched hand, or a hemi-spherical camera rig used for multi-view scene capture. However, traditional structure-from-motion pipelines tend
Lines and points are complementary local features, whose combination has proven effective for applications such as SLAM and Structure-from-Motion. The backbone of these pipelines are the local feature matchers, establishing correspondences across images. Traditionally, point and line matching have been treated as independent tasks. Recently, GlueStick proposed a GNN-based network that simultane-ou
BACKGROUND: Early-life exposure to per- and polyfluoroalkyl substances (PFAS) may impact the developing lungs and immune system and increase the risk of childhood asthma, but no studies have been conducted in a high-exposed population. The objective of this study was to estimate associations between prenatal PFAS exposure and childhood incidence of asthma and wheeze in Blekinge County, Sweden, whe
BackgroundSuicide is a leading cause of premature mortality worldwide, but the impact of system-level mental health resources remains unclear despite the central role of psychiatric inpatient care and declining bed capacity. Prior research has yielded inconsistent findings with limited control for confounding. We aimed to estimate the effect of psychiatric inpatient bed availability on suicide mor
In a microbial fuel cell (MFC), exoelectrogens, which transfer electrons to the electrode, have been regarded as a key factor for electricity generation. In this study, U-tube MFC and plating methods were used to isolate exoelectrogens from the anode of an MFC. Disparate microorganisms were identified depending on isolation methods, despite the use of an identical source. Denaturing gel gradient e
Hydraulic balancing is key to ensure proper operation of the heating system. When the heating system is not hydraulically balanced, heat is unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage of energy. In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variabl
Energy efficiency programmes (EEPs) are schemes operated by utilities or other bodies in order to incentivize energy efficiency improvement, in particular by adoption of energy-efficient products and typically by means of an economic reward. Ample experience has been gained, especially in the U.S., where EEPs have been in use for decades, with the rationale of avoiding additional energy supply by
Hydraulic balancing of heat distribution systems in buildings plays an important role in improving indoor thermal conditions as well as reducing energy consumption for space heating. Building energy models typically do not incorporate thermal comfort while it is essential for hydraulic balancing to do so. This paper proposes a methodology that assesses the impact of hydraulic balancing on the ener
In the Swiss canton of Geneva, an energy efficiency portfolio has been operated since 2009. In contrast, such programs have been in place for more than 40 years in the US. There are numerous lessons to be learnt from their experience. We have therefore conducted a comparative analysis including Geneva and 11 leading states in the US, with the objective to identify explanatory factors for the succe
Heating systems must be subjected to hydraulic balancing in order to ensure proper operation. When the heating system is hydraulically imbalanced, heat is unevenly distributed across dwellings resulting in a large temperature spread, overheating, and consequently, waste of energy. In this study, we investigate the extent to which hydraulic imbalance affects the thermal energy consumption in buildi
The final day of the conference opened with Albin Thörn Cleland’s presentation, “Hidden Choral Stimuli: The Role of Accent in Aristophanes’ Refrains”. His paper examined the interplay of pitch accent, metre and musical melody across metrically identical refrains in pre-Hellenistic Ancient Greek lyric poetry, an aspect that has long remained relatively obscure and misunderstood. Building on Conser
A thorough understanding of the longitudinal phase space (LPS) of the electron beam is of great advantage to any modern linear accelerator (linac), and of critical importance for operating a free electron laser (FEL). While a transverse deflecting structure (TDS) allows full characterization of a beam’s LPS, measurements with a TDS system are often destructive and operationally complex.

Bakgrund: En positiv förlossningsupplevelse är målet för hela vårdkedjan under graviditet, födsel och eftervård. WHO betonar vikten av en positiv förlossningsupplevelse och inte endast mor och barns säkerhet. Trots detta upplever fortfarande många kvinnor sin förlossning som negativ. Barnmorskan handlägger den normala förlossningen självständigt och ska i samband med detta ge den födande kvinnan s
Olof Risberg skriver om undersökningen som metod och möjligt verktyg för makt över arbetsplatsen. I den historiska exposén Att undersöka (biblioteks)arbete sätts tayloristiska undersökningar av fabriksarbete i relation till militanta undersökningar och bibliotekarieskråets ansträngningar för att förstå och ta kontroll över sitt arbete.

Birger Sjöberg arbetade under 1926 på en plan, Drömmeriidkarna, som var ett förstadium till Kriser och kransar (1926) Grundvalen för rekonstruktionen av denna plan är manuskript i Sjöberg-arkivet vid Göteborgs universitetsbibliotek. Rekonstruktionen är en kommenterad, textkritisk utgåva.
