Pump-probe polarization anisotropy measurements with 15 fs pulses are employed to investigate the electronic structure of PbS quantum dots. The initial anisotropy at the bandgap is anomalously low (

The first low-energy Coulomb-excitation measurement of the radioactive, semi-magic, two proton-hole nucleus 206Hg, was performed at CERN's recently-commissioned HIE-ISOLDE facility. Two γ rays depopulating low-lying states in 206Hg were observed. From the data, a reduced transition strength B(E2; 2+1 → 0+1) = 4.4(6) W.u. was determined, the first such value for an N=126 nucleus south of 208Pb, whi

A recent case of a flawed medical AI system that was backed by public funding provides an opportunity to discuss the impact of government policies and regulation in AI.

Multi-gigawatt-scale hydrogen production by water electrolysis is central in the green transition when it comes to storage of energy and forming the basis for sustainable fuels and materials. Alkaline water electrolysis plays a key role in this context, as the scale of implementation is not limited by the availability of scarce and expensive raw materials. Even though it is a mature technology, th

This article addresses the development under Xi Jinping of ideological and political education at the university level. It provides an overview of trends among youth, major policies and recent developments, and an analysis of how ideological and political education is organised at universities and incorporated into the curricula. It also argues that ideological and political education targeting yo

The increasing investment in and emphasis on ideological andpolitical education at Chinese universities, and statements, including by Xi Jinping himself, and other policies related to youth and higher education, reveals a growing concern about youth. This article provides a brief overview of developments and policies affecting Chinese youth, including the emergence of new values among them.

OBJECTIVE: The aim of this study was to investigate if desquamated oral epithelial cells (DOECs) express the epidermal growth factor (EGF) and if these cells thereby may contribute to salivary EGF contents.BACKGROUND: DOECs have recently been shown to harbor the antimicrobial peptide LL-37, proposing that they may also store other biologically important salivary peptides/proteins. The EGF peptide

Aims: Use of left ventricular assist devices (LVADs) in older patients has increased, and assessing outcomes in older LVAD recipients is important. Therefore, this study aimed to investigate associations between age and outcomes after continuous-flow LVAD (cf-LVAD) implantation. Methods and results: Cf-LVAD patients from the multicentre European PCHF-VAD registry were included and categorized into

Mycket har sagts och skrivits om polarisering men sällan med några historiska tillbakablickar. Ibland kan det nästan framstå som att polarisering är ett helt nytt fenomen.I den här boken vänder åtta idéhistoriker på perspektivet och argumenterar för att företeelsen är lätt att finna även i det förgångna. Skribenterna ger oss inblickar i polariserade situationer och konflikter som

Introduction: In factor VIII (FVIII) prophylaxis for haemophilia A, cost comparisons have used price per international unit (IU) based on the once reasonable assumption of equivalent outcome per IU. Now, with several extended half-life (EHL) products available, new outcome-oriented ways to compare products are needed. Area under the curve (AUC) quantifies FVIII levels over time after infusion prov

This study examines the extent of the gap between the proportions of survey respondents reporting (1) having the possibility to use and (2) using special transport services (STS) compared to the corresponding gaps for other transport modes. For persons eligible for STS, differences between those who use them and those who do not use them are explored. The frequencies with which these two groups le

Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co-occurring alpine plants, we 1) determined the extent of species-specific microclimate modification by comparing temperature and soil moisture between vegetated

Background: Survivors of Hodgkin lymphoma (HL) are at risk of developing non-Hodgkin lymphoma (NHL) after treatment; however, the risks of developing subsequent primary lymphomas (SPLs), including HL and NHL, after different types of childhood cancer are unknown. The authors quantified the risk of SPLs using the largest cohort of childhood cancer survivors worldwide. Methods: The Pan-European Netw
