Resonant inelastic x-ray scattering at the N2 π∗ resonance : Lifetime-vibrational interference, radiative electron rearrangement, and wave-function imaging RESONANT INELASTIC X-RAY SCATTERING at the ... L. KJELLSSON et al.

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

Does Democratization Cause Redistribution? Evidence from Sweden and Brazil

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.

Ab initio multiconfiguration Dirac-Hartree-Fock calculations of the in and Tl electron affinities and their isotope shifts

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

Local structure of Nb in superconducting Nb-doped Bi2Se3

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

Intershell interactions in correlated materials : A slave-rotor approach

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

Magnetization-induced optical rectification and inverse spin Hall effect for interfacial terahertz generation in metallic heterostructures

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

Dynamic impurities in two-dimensional topological-insulator edge states

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

Correlation studies of fission-fragment neutron multiplicities

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

Blylav återfunnen i Padjelanta nationalpark efter 79 år

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,

Brokerage activity, exclusivity and role diversity: A three-dimensional approach to brokerage in networks

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

Navigating conflicting desires: parenting practices and the meaning of educational work in urban East Asia

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

AbspectroscoPY, a Python toolbox for absorbance-based sensor data in water quality monitoring

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

Risk-Based Evaluation of Improvements in DrinkingWaterTreatment Using Cost-Benefit Analysis

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

Problematising Definition of Social Resilience: A Scoping Review of Popular Definitions.

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

Pre-activation negativity (PrAN) : A neural index of predictive strength of phonological cues

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

Phonetics in the Brain

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

Prevalence Estimates of Amyloid Abnormality Across the Alzheimer Disease Clinical Spectrum.

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

Λc+ production in pp and in p -Pb collisions at sNN =5.02 TeV

The production cross section of prompt Λc+ charm baryons was measured with the ALICE detector at the LHC at midrapidity in proton-proton (pp) and proton-lead (p-Pb) collisions at a center-of-mass energy per nucleon pair of sNN=5.02TeV. The Λc+ and Λ¯c- baryons were reconstructed in the hadronic decay channels Λc+→pK-π+ and Λc+→pKS0 and respective charge conjugates. The measured differential cross

Double-parton scattering mechanism for associated c c ¯ l+l- production in AA ultraperipheral collisions as a probe for the photon density inside the nucleus

We discuss the associated cc¯ and l+l- pairs production in ultraperipheral heavy-ion collisions at high energies. Such a channel provides a novel probe for double-parton scattering (DPS) at small x enabling one to probe the photon density inside the nucleus. We have derived an analog of the standard central pp pocket formula and studied the kinematical dependence of the effective cross section. Ta
