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
Introduction: Antibodies targeting the blood-stage of Plasmodium falciparum play a critical role in naturally acquired immunity to malaria by limiting blood-stage parasitemia. One mode of action of antibodies is the direct inhibition of merozoite invasion of erythrocytes through targeting invasion ligands. However, evasion of inhibitory antibodies may be mediated in P. falciparum by switching betw
Introduction: Impulse control and related behavioral disorders (ICBDs) commonly complicate Parkinson’s disease (PD) course. The ICBDs spectrum encompasses two groups of conditions, with distinct pathophysiology: proper ‘impulse control disorders (ICDs)’ (e.g. gambling) and the ‘ICDs related disorders (ICDs-RD)’ (e.g. punding). Behavioral disturbances are associated with dopamine replacement therap
Background: The optimal timing of anticoagulation for patients with acute ischaemic stoke with atrial fibrillation is uncertain. We investigated the efficacy and safety of early compared with delayed initiation of direct oral anticoagulants (DOACs) in patients with acute ischaemic stroke associated with atrial fibrillation. Methods: We performed a multicentre, open-label, blinded-endpoint, paralle
Critical urbanists’ placement of smart city initiatives in Western Europe or North merica mostly on “low” rungs of participatory ladders or scaffolds does not mean that smart urban development connotes democracy-eroding neoliberalization everywhere. This article offers a more globally variegated and dynamic understanding of the relationship between citizens and smart cities. We apply an institutio
Surveys in the Milky Way and Large Magellanic Cloud have revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary properties of massive stars at low metallicity, and therefore in conditions approaching those of the Early Universe, remain sparse. We present the Binarity at LOw Metallicity (BLOeM) campaign, an ESO large programme
Currently, most research and public datasets for video sports analytics are base on detecting players as bounding boxes in broadcast videos. Going from there to precise locations on the pitch is however hard. Modern solutions are making dedicated static cameras covering the entire pitch more readily accessible, and they are now used more and more even in lower tiers. To promote research that can t
Among small birds the great tit Parus major stands out as especially good at performing various cognitive tasks that are impressive to humans. It may, for example, knock on kitchen windows to get bird feeder refills, drum on beehives in winter to lure the bees to come walking out, perch in flowering fruit trees and kill incoming bumblebee queens and large butterflies, give false alarm calls in ord
Sweden's feminist foreign policy (FUP), which was pursued between 2014 and 2022, involved a more strategic anchoring and communication of the country's state feminist tradition and commitment to justice in world politics. The emphasis on gender equality as the basis for foreign policy was largely based on the UN's agenda for women, peace, and security (WPS). Digital diplomacy and social media, whi
This study investigates strategies for igniting hydrogen in compression ignition engines, a process traditionally hindered by hydrogen’s high ignition temperature. In conventional dual-fuel engines, a small diesel pilot is often used to ignite hydrogen, taking advantage of diesel’s lower ignition temperature to initiate combustion. While effective, this approach introduces carbon emissions, limiti
Aim: To explore the possibility of reducing the diagnostic burden in children with prenatally detected unilateral ureteropelvic junction obstruction. Methods: Children with unilateral ureteropelvic junction obstruction (2012–2020) were identified from a prenatal hydronephrosis registry. The frequency of adverse events, predictors for event-free follow-up beyond 1 year of age, and examination burde
The first measurement of the multiplicity dependence of intra-jet properties of leading charged-particle jets in proton–proton (pp) collisions is reported. The mean charged-particle multiplicity and jet fragmentation distributions are measured in minimum-bias and high-multiplicity pp collisions at center-of-mass energy s = 13 TeV using the ALICE detector. Jets are reconstructed from charged partic
Background: Cardiac surgery carries a heightened risk of bradyarrhythmias, but current permanent pacemaker (PPM) implantation estimates rely on non-contemporary studies. This study primarily aimed to explore the incidence and indications for PPM implantation at 30 days and 1 year after different cardiac surgical procedures in a modern cohort. Secondary outcomes were PPM incidence at 10 years and t
The study aims to move beyond idealised and predominantly trait-based typologies of leadership and leadership roles and addresses collegial leaders’ practice of change in higher education. Collegial leaders at two research-intensive higher education institutions, who had received educational leadership training, were studied. In the study, we explored ordinary actions and change practices as a way
We study authentic leadership as a prominent but problematic example of positive leadership that we use as a more general “warning” against the current fashion of excessive positivity in leadership studies. Without trying to cover “everything”, we critically examine the principal tenets of mainstream authentic leadership theory and reveal a number of fundamental flaws: shaky philosophical and theo
Prefabricated housing is a disruptive innovation struggling to take hold in a traditional complex product system (CoPS). It is quicker to produce and has improved environmental performance compared to traditional housing. CoPS have more dense and complex network connections than commodity industries, making disruptive innovation more difficult. Effective relational capabilities can achieve the coo
Importance: Plasma neurofilament light (NfL) has been suggested as a noninvasive biomarker to monitor neurodegeneration in Alzheimer disease (AD), but studies are lacking. Objective: To examine whether longitudinal plasma NfL levels are associated with other hallmarks of AD. Design, Setting, and Participants: This North American cohort study used data from 1583 individuals in the multicenter Alzhe
Purpose: To study the feasibility of automatically identifying normal digital mammography (DM) exams with artificial intelligence (AI) to reduce the breast cancer screening reading workload. Methods and materials: A total of 2652 DM exams (653 cancer) and interpretations by 101 radiologists were gathered from nine previously performed multi-reader multi-case receiver operating characteristic (MRMC
