Individuals are expected to avoid mating with relatives as inbreeding can reduce offspring fitness, a phenomenon known as inbreeding depression. This has led to the widespread assumption that selection will favour individuals that avoid mating with relatives. However, the strength of inbreeding avoidance is variable across species and there are numerous cases where related mates are not avoided. H

Resonant inelastic x-ray scattering spectra excited at the π∗-resonance of the nitrogen molecule are presented. Well-resolved vibrational excitations in the electronic ground state, and in the 3σg-11πg1a1Πg state are observed. The spectra are analyzed within the Kramers-Heisenberg formalism, and the importance of lifetime-vibrational interference effects is highlighted. In addition, strongly disso

This paper explores the relationship between democratization and economic redistribution using case study analysis applied to Sweden and Brazil. We find that democratization is intimately connected to redistribution through the welfare state, but as an event in itself is neither a necessary nor a sufficient cause of redistributive reforms. Democratization is not strictly necessary, because in antiThis paper explores the relationship between democratization and economic redistribution using case study analysis applied to Sweden and Brazil.

We report multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction calculations on the thallium (Tl) electron affinity, as well as on the excited energy levels arising from the ground configuration of Tl-. The results are compared with the available experimental values and further validated by extending the study to its homologous, lighter element, indium (In), belonging to

In the prospect of realizing bulk superconductivity in a topological insulator, metal-doped Bi2Se3 has been investigated with increased interest, where the Cu-, Sr-, and Nb-doped systems appear particularly promising. It is generally assumed that metal intercalation into the van der Waals (vdW) gap is responsible for the superconductivity. We have investigated the local structure of Nb in samples

The treatment of intershell interactions remains a major challenge in the theoretical description of strongly correlated materials. Most previous approaches considered the influence of intershell interactions at best in a static fashion, neglecting dynamic effects. In this paper, we propose a slave-rotor method that goes beyond this approximation by incorporating the effect of intershell interacti

Metallic heterostructure as promising terahertz (THz) spintronic emitters has promoted the development of both spintronics and THz science. However, the underlying physics at the metallic interface, such as the nonlinear optical effect, remains unclear. Herein, we present interface magnetization induced THz generation from metallic heterostructure consisting of Heusler alloy CoFeMnSi (CFMS) and Pd

Helical edge states of two-dimensional topological insulators show a gap in the density of states (DOS) and suppressed conductance in the presence of ordered magnetic impurities. Here we will consider the dynamical effects on the DOS and transmission when the magnetic impurities are driven periodically. Using the Floquet formalism and Green's functions, the system properties are studied as a funct

We calculate neutron multiplicities from fission fragments with specified mass numbers for events having a specified total fragment kinetic energy. The shape evolution from the initial compound nucleus to the scission configurations is obtained with the metropolis walk method on the five-dimensional potential-energy landscape, calculated with the macroscopic-microscopic method for the three-quadra

Padjelanta nationalpark har en exceptionellt artrik och fort­ farande till stor del okänd lavflora inklusive många sällsynta eller rödlistade arter. Lavforskaren Gunnar Degelius hittade 1941 den rödlistade blylaven på ett klippblock vid fjället Unna Duvgge på sydvästra stranden av Virihaure vilket är den nordligaste lokalen för arten i Sverige. Sommaren 2020 återfann vi blylaven efter 79 långa år,

The purpose of this paper is to connect central theoretical contributions to the study of brokerage and propose a novel conceptual and analytical approach for investigating it. On one hand, it builds on, and further substantiate the utility of, the innovation of conceptualizing brokerage activity and brokerage exclusivity separately, whilst analyzing them together. On the other hand, it also build

Today parents are faced with increasing expectations to attend to their young children’s learning and cognitive development. South Korea and Singapore are well-known for their competitive education systems and for consistently topping international student assessment tests. They also share an inflated private tuition industry, fuelled by the assumption that parents are compelled to invest substant

The long-term trend of increasing natural organic matter (NOM) in boreal and north European surface waters represents an economic and environmental challenge for drinking water treatment plants (DWTPs). High-frequency measurements from absorbance-based online spectrophotometers are often used in modern DWTPs to measure the chromophoric fraction of dissolved organic matter (CDOM) over time. These d

Reliable and safe drinking water supply requires adequate risk management. Decisionsupport models can aid decisionmakers to effectively evaluate risk mitigation measures and allocatesocietal resources. Here, a Swedish case study illustrates how the installation of ultrafiltrationmembranes can be evaluated by combining risk assessment and cost-benefit analysis. Quantitativemicrobial risk assessment

Social resilience is relatively new rarely explored concept. In 21st century, it is becoming significant in sustainability studies in the context of social wellbeing and its impact on quality of life. The concept of social resilience is frequently associated withpredominant conceptualisation of resilience in Psychology. However, it goes beyond the narrow definition of resilience by assessing indiv

We propose that a recently discovered event-related potential (ERP) component—the pre-activation negativity (PrAN)—indexes the predictive strength of phonological cues, including segments, word tones, and sentence-level tones. Specifically, we argue that PrAN is a reflection of the brain’s anticipation of upcoming speech (segments, morphemes, words, and syntactic structures). Findings from a long

Spoken language is a rapidly unfolding signal: a complex code that the listener must crack to understand what is being said. From the structures of the inner ear through to higher-order areas of the brain, a hierarchy of interlinked processes transforms the acoustic signal to a linguistic message within fractions of a second.This Element outlines how speech is perceived and explores what the audit

Importance: One characteristic histopathological event in Alzheimer disease (AD) is cerebral amyloid aggregation, which can be detected by biomarkers in cerebrospinal fluid (CSF) and on positron emission tomography (PET) scans. Prevalence estimates of amyloid pathology are important for health care planning and clinical trial design.Objective: To estimate the prevalence of amyloid abnormality in p
