Observation of Rabi dynamics with a short-wavelength free-electron laser

Rabi oscillations are periodic modulations of populations in two-level systems interacting with a time-varying field 1. They are ubiquitous in physics with applications in different areas such as photonics 2, nano-electronics 3, electron microscopy 4 and quantum information 5. While the theory developed by Rabi was intended for fermions in gyrating magnetic fields, Autler and Townes realized that

Early and late improvement in a two‐year out‐patient alcoholic treatment programme

Abstract— The process of improvement was studied in a 2‐year out‐patient programme for alcoholics. The drop‐out rate was 16%. The analysis was based on recurrent evaluations of treatment contracts including both drinking pattern and psycho‐social treatment objectives. Background data were related to the alcohol adjustment during the first but not during the second year of treatment. Subjects with

Adoption, adaptation or chance? Inter-organisational diffusion of the protection of civilians norm from the UN to the African Union

Norms can be adopted without modifications or adapted to regional contexts for strategic or principled reasons. Norm adoption and adaptation can also happen by chance. When adoption takes place without consideration of the norm’s effectiveness or appropriateness, we speak about imitation. When adaptation takes place in such a manner, we lack conceptual tools to analyse it. We propose a novel conce

Nep-hop for peace? Political visions and divisions in the booming Nepalese hip-hop scene

This article explores the burgeoning Nepalese hip-hop scene – commonly known as nep-hop – as a discursive intervention in the post-war politics of Nepal. Its core argument is that nep-hop oftentimes demonstrates an ethos of peacebuilding through popular culture. Indeed, many songs explicitly criticize violence, war, and the political leaders who recently brought the nation to a civil war. Yet, thi

Challenges related to self-assessment of active ageing during the Covid-19 pandemic in Sweden

Objective: The aim is to describe and reflect upon potentially pandemic-related impact on self-assessments of active ageing. As part of the baseline data collection in the Prospective RELOC-AGE (ClinicalTrials.gov NCT04765696) study, telephone interviews, including the University of Jyvaskyla Active Aging Scale (UJACAS) were conducted with 820 people 55 years or older listed with an interest of re

Agents of Altruism : The Great Irish Famine and Italian Civil Society

This article analyses the participation of individuals, networks and international organizations in transnational fundraising aimed at providing humanitarian relief aid. Focusing on fundraising campaigns organized in the Italian states in favour of Ireland in 1847, when the Great Famine scourged its population the most, the article highlights the agency of the fundraisers in setting in motion an e

Cold winters have morph-specific effects on natal dispersal distance in a wild raptor

Dispersal is a key process with crucial implications in spatial distribution, density, and genetic structure of species' populations. Dispersal strategies can vary according to both individual and environmental features, but putative phenotype-by-environment interactions have rarely been accounted for. Melanin-based color polymorphism is a phenotypic trait associated with specific behavioral and p

A Review of Millimeter Wave Device-based Localization and Device-free Sensing Technologies and Applications

The commercial availability of low-cost millimeterwave (mmWave) communication and radar devices is starting to improve the adoption of such technologies in consumer markets, paving the way for large-scale and dense deployments in fifthgeneration (5G)-and-beyond as well as 6G networks. At the same time, pervasive mmWave access will enable device localization and device-free sensing with unprecedent

Evaluating staging habitat quality to advance the conservation of a declining migratory shorebird, Red Knot Calidris canutus

Identifying where and when population ‘bottlenecks’ occur is critical to the conservation of migratory species, many of which are declining precipitously worldwide. Especially challenging is the evaluation of changes to staging sites. These sites are indispensable links in the migratory cycle but are typically used only briefly. We devised a field-based approach to assess the quality and carrying

Boundary-Monte Carlo Method for Neutral and Charged Confined Fluids

In this work, we describe a new Monte Carlo (MC) simulation method to investigate highly coupled fluids in confined geometries at a constant chemical potential. This method is based on so-called multi-scale Hamiltonian methods, wherein the chemical potential is determined using a more amenable Hamiltonian for a fluid in an "outer"region, which facilitates standard methods, such as grand canonical

Surgery for Lumbar Spinal Stenosis in Patients With Mild Leg Pain Levels Is Associated With Unsatisfactory Outcome

Study Design: Prospective register cohort study. Objectives: The indication for surgery in patients with lumbar spinal stenosis (LSS) is considered to be leg pain and neurogenic claudication (NC). Nevertheless, a significant part of patients operated for LSS have mild leg pain levels defined as leg pain ≤minimally important clinical difference (MICD). Information is lacking on how to inform these

A Highly Settled Disk around Oph163131

High dust density in the midplane of protoplanetary disks is favorable for efficient grain growth and can allow fast formation of planetesimals and planets, before disks dissipate. Vertical settling and dust trapping in pressure maxima are two mechanisms allowing dust to concentrate in geometrically thin and high-density regions. In this work, we aim to study these mechanisms in the highly incline

The enactment of physician-authors in Nobel Prize nominations

Several physicians have been nominated for the Nobel Prize in literature, but so far none of them have received it. Because physicians as women and men of letters have been a major topic of feuilletons, seminars and books for many years, questions arise to what extent medicine was a topic in the proposals for the Nobel Prize and in the Nobel jury evaluations: how were the nominees enacted (or not)Several physicians have been nominated for the Nobel Prize in literature, but so far none of them have received it.

Impaired cerebral oxygenation in heart failure patients at rest and during head-up tilt testing

AIMS: Heart failure (HF) confers potentially negative effects on the brain and autonomic nervous system. The measurement cerebral tissue oxygen saturation (SctO2 ) may aid in understanding such effects. We aimed to investigate if compensated HF affects SctO2 at rest and during orthostatic challenge.METHODS AND RESULTS: Non-invasive haemodynamic monitoring and near-infrared spectroscopy were applie

A single-host fermentation process for the production of flavor lactones from non-hydroxylated fatty acids

Lactone flavors with fruity, milky, coconut, and other aromas are widely used in the food and fragrance industries. Lactones are produced by chemical synthesis or by biotransformation of plant-sourced hydroxy fatty acids. We established a novel method to produce flavor lactones from abundant non-hydroxylated fatty acids using yeast cell factories. Oleaginous yeast Yarrowia lipolytica was engineere

A physiology-based Earth observation model indicates stagnation in the global gross primary production during recent decades

Earth observation-based estimates of global gross primary production (GPP) are essential for understanding the response of the terrestrial biosphere to climatic change and other anthropogenic forcing. In this study, we attempt an ecosystem-level physiological approach of estimating GPP using an asymptotic light response function (LRF) between GPP and incoming photosynthetically active radiation (P

Knowledge transfer for large scale vaccine manufacturing

As the world rushes to identify safe and effective vaccines and therapeutics to counter the COVID-19 epidemic, attention is turning to the next step: manufacturing these products at enormous scale. To speed up the process, firms are even es-tablishing manufacturing capacity “at risk,” before products receive regulatory approval (1). Yet for at least some complex COVID-19 vaccines and biological th

AbstractObjective To evaluate and compare benefits and harms of three biological treatments with different modes of action versus active conventional treatment in patients with early rheumatoid arthritis. Design Investigator initiated, randomised, open label, blinded assessor, multiarm, phase IV study. Setting Twenty nine rheumatology departments in Sweden, Denmark, Norway, Finland, the Netherland
