Impact of different compilers and build types on Geant4 simulation execution time

Experimental observations and advanced computer simulations in High Energy Physics (HEP) paved the way for the recent discoveries at the Large Hadron Collider (LHC) at CERN. Currently, Monte Carlo simulations account for a very significant amount of computational resources of the Worldwide LHC Computing Grid (WLCG). The current growth in available computing performance will not be enough to fulfil

New developments in cost modeling for the LHC computing

The increase in the scale of LHC computing during Run 3 and Run 4 (HL-LHC) will certainly require radical changes to the computing models and the data processing of the LHC experiments. The working group established by WLCG and the HEP Software Foundation to investigate all aspects of the cost of computing and how to optimise them has continued producing results and improving our understanding of

Sweden, the United States, and Raoul Wallenberg's Mission to Hungary in 1944

This article provides an in-depth examination of the U.S. government's role in the case of Raoul Wallenberg, the courageous Swedish envoy who died mysteriously in the Soviet Union after being arrested by Soviet occupation forces at the end of World War II for unknown reasons. The article recounts how U.S. officials, particularly the diplomat Herschel V. Johnson, tried to alleviate the plight of Hu

Reframing Immigrant Resistance : Alliances, Conflicts, and Racialization in Italy

This book focuses on the political participation and grassroots mobilization of immigrants and racialized communities in the European context. Based on extensive data collected in Italy, it explores the role that alliances among pro-immigrant groups play in shaping political participation, asking why and how immigrant activists mobilize in hostile environments, why and how they create alliances wi

Structural Breaks in Interactive Effects Panels and the Stock Market Reaction to COVID-19

Dealing with structural breaks is an essential step in most empirical economic research. This is particularly true in panel data comprised of many cross-sectional units, which are all affected by major events. The COVID-19 pandemic has affected most sectors of the global economy; however, its impact on stock markets is still unclear. Most markets seem to have recovered while the pandemic is ongoin

Factor H binds to washed human platelets

Background: Factor H regulates the alternative pathway of complement. The protein has three heparin-binding sites, is synthesized primarily in the liver and copurifies from platelets with thrombospondin-1. Factor H mutations at the C-terminus are associated with atypical hemolytic uremic syndrome, a condition in which platelets are consumed. Objectives The aim of this study was to investigate if f

Circulating Markers of Neutrophil Extracellular Traps (NETs) in Patients With Ovarian Tumors

BACKGROUND/AIM: Inflammation is a hallmark of cancer, and the role of neutrophils and neutrophil extracellular traps (NETs) in cancer and cancer-associated thrombosis has attracted a lot of interest. The NET-specific marker H3Cit has been found to be elevated in the plasma of patients with malignancies, suggesting NETs markers as novel cancer biomarkers. This study aimed to determine the levels of

Lessons Learned from a Study on Distractions in Virtual Learning Environments : Reliability, Ecological Validity, and an Elusive Social Component

Virtual Reality has long been proposed to combine the reliability of controlled laboratory settings with the ecological validity of real life. While the technological development steadily pushes towards even more realistic renderings of the real world— the elusiveness of social and emotional elements gradually becomes more evident. This is not the least true for behavioral studies in rich sociocul

On the fractional susceptibility function of piecewise expanding maps

We associate to a perturbation (ft) of a (stably mixing) piecewise expanding unimodal map f0 a two-variable fractional susceptibility function Ψφ(η, z), depending also on a bounded observable φ. For fixed η ∈ (0, 1), we show that the function Ψφ(η, z) is holomorphic in a disc Dη ⊂ C centered at zero of radius > 1, and that Ψφ(η, 1) is the Marchaud fractional derivative of order η of the function t

Installation of O-glycan sulfation capacities in human HEK293 cells for display of sulfated mucins

The human genome contains at least 35 genes that encode Golgi sulfotransferases that function in the secretory pathway, where they are involved in decorating glycosaminoglycans, glycolipids, and glycoproteins with sulfate groups. Although a number of important interactions by proteins such as selectins, galectins, and sialic acid-binding immunoglobulin-like lectins are thought to mainly rely on su

Indicator frameworks for fostering open knowledge practices in science and scholarship

The aim of this report is to contribute to the European vision for Open Science (European Commission 2016) by providing the frameworks for understanding and applying science and technology indicators, defined broadly, to enable the transition from the current scientific and scholarly system towards a more open and inclusive configuration of knowledge practices and infrastructures. Indicators for O

Glucose as a marker of fluid absorption in bipolar transurethral surgery.

BACKGROUND: Historically, a reduced serum sodium concentration has been used to diagnose absorption of electrolyte-free irrigating fluid during transurethral resection of the prostate (TURP). In bipolar TURP, the irrigating solution contains electrolytes, thus invalidating the serum sodium method. In this study, we investigated whether glucose can be used to diagnose the absorption of irrigating f

Facing a pandemic: African armies and the fight against COVID-19

The goal of this report is to empirically study the domestic deployment of militaries to manage the pandemic on the African continent. In this perspective, the COVID-19 crisis is a case study of continuity and change: both within civil-military relations more broadly and within the armed forces in particular. The report focuses on four cases: Sierra Leone by Maggie Dwyer and Osman Gbla; Burkina Fa

A framework for participatory work environment interventions in home care – success factors and some challenges

BackgroundHome care is beset with work environment issues and high staff turnover, while research concerned with interventions to improve the work environment is sparse. Few of the existing interventions apply a participative approach, despite this being associated with more positive outcomes and sustainable change. This paper presents a framework, rooted in action research and action learning, fo

Cardiovascular Magnetic Resonance in Right Heart and Pulmonary Circulation Disorders

Right heart and pulmonary circulation disorders are generally caused by right ventricle (RV) pressure overload, volume overload, and cardiomyopathy, and they are associated with distinct clinical courses and therapeutic approaches, although they often may coexist. Cardiac magnetic resonance (CMR) provides a noninvasive accurate and reproducible multiplanar anatomic and functional assessment, tissu

My Fault or Default—Household Behaviors Living in a Climate-Smart Building

Decreasing climate impact of households is a concern for many actors. One way to address this challenge is to focus on household behaviors related to energy use and consumption. Another is to construct climate-smart houses that encourage households to utilize smart functions that reduce emissions. This article examines the link between these two strategies and investigates how living in a climate-
