Attosecond delays in laser-assisted photodetachment from closed-shell negative ions

We study laser-assisted photodetachment time delays by attosecond pulse trains from the closed-shell negative ions F− and Cl−. We investigate the separability of the delay into two contributions: (i) the Wigner-like delay associated with one-photon ionization by the attosecond pulse train and (ii) the delay associated with the exchange of an additional laser photon in the presence of the potential

Inflammatory potential of diet and risk of lymphoma in the European Prospective Investigation into Cancer and Nutrition

Introduction: Chronic inflammation plays a critical role in lymphomagenesis and several dietary factors seem to be involved its regulation. The aim of the current study was to assess the association between the inflammatory potential of the diet and the risk of lymphoma and its subtypes in the European Investigation into Cancer and Nutrition (EPIC) study. Methods: The analysis included 476,160 sub

Eliminating the dipole phase in attosecond pulse characterization using Rydberg wave packets

We propose a technique to fully characterize the temporal structure of extreme ultraviolet pulses by ionizing a bound coherent electronic wave packet. The influence of the dipole phase, which is the main obstacle for state-of-the-art pulse characterization schemes, can be eliminated by angle integration of the photoelectron spectrum. We show that in particular, atomic Rydberg wave packets are idea

Postnatal intervention for the treatment of FNAIT : a systematic review

Objective: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is associated with life-threatening bleeding. This systematic review of postnatal management of FNAIT examined transfusion of human platelet antigen (HPA) selected or unselected platelets, and/or IVIg on platelet increments, hemorrhage and mortality. Study design: MEDLINE, EMBASE and Cochrane searches were conducted until 11 May 20

Outcomes of patients with systemic sclerosis treated with rituximab in contemporary practice : A prospective cohort study

Objective: To assess the safety and efficacy of rituximab in systemic sclerosis (SSc) in clinical practice. Methods: We performed a prospective study including patients with SSc from the European Scleroderma Trials and Research (EUSTAR) network treated with rituximab and matched with untreated patients with SSc. The main outcomes measures were adverse events, skin fibrosis improvement, lung fibros

Kris i naturen – vår existens har blivit sårbar

Fler arter än någonsin i mänsklighetens historia hotas av utrotning och den biologiska mångfalden lokalt har förändrats kraftigt i en stor del av världens ekosystem. Grundläggande förändringar behövs både i samhället och för individer, för att bromsa den negativa trenden, skriver en rad debattörer.

Utveckling av kommunala risk- och sårbarhetsanalyser

Denna rapport utgör redovisning av ett arbete som LUCRAM (Lunds universitets centrum för riskanalys och riskhantering) har genomfört på uppdrag av Myndigheten för samhällsskydd och beredskap (MSB). Uppdraget heter ”Studie om föreskrifters inverkan på kommuners risk- och sårbarhetsanalyser avseende jämförbarhet och enhetlighet”. Inom detta uppdrag har LUCRAM genomfört en dokumentstudie av kommunala

Nordic representations of North Korea : A study of newspaper sources

International media regularly portray North Korea as abnormal, run by a leadership depicted in turns as evil, incompetent, all-powerful, and farcical. Such representations provide reason for publics not to question American-led preferences, dominant until 2018, for sanctions and threats over dialogue when responding to weapons development. How does a region beyond the Asia-Pacific, home to potenti

Improved characterization of dryland degradation using trends in vegetation/ rainfall sequential linear regression (SERGS-TREND)

Land degradation in drylands has been investigated extensively over recent decades and several remote sensing based techniques attempt to decouple the human influence from the natural climate variability, but are contested in literature. We introduce a novel approach termed SeRGS-TREND that is designed to monitor land degradation by suppressing the impact from climate variability and highlight veg
