We study the problem of characterizing the cyclic vec-tors in de Branges-Rovnyak spaces. Based on a description of theinvariant subspaces we show that the difficulty lies entirely in un-derstanding the subspace (aH2)⊥ and give a complete function the-oretic description of the cyclic vectors in the case dim(aH2)⊥ < ∞.Incidentally, this implies analogous results for certain generalizedDirichlet spac

Poeten och konstnären Öyvind Fahlström (1928–1976) är en av ytterst fåinternationellt kända svenska konstnärer under 1900-talet. När han och hansfru, bildkonstnären Barbro Östlihn, flyttade till New York 1961 kom de attbli en naturlig del av det framväxande neoavantgardet, och Fahlström erövrade omedelbart en central position i rörelsen tillsammans med framträdande konstnärer som Robert Rauschenbe

Particle physics today faces the challenge of explaining the mystery of dark matter, the origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent fine-tuning of the electro-weak scale, and many other aspects of fundamental physics. Perhaps the most striking frontier to emerge in the search for answers involves new physics at mass scales comparable to famil

Quantification of land surface-atmosphere fluxes of carbon dioxide (CO2) and their trends and uncertainties is essential for monitoring progress of the EU27+UK bloc as it strives to meet ambitious targets determined by both international agreements and internal regulation. This study provides a consolidated synthesis of fossil sources (CO2 fossil) and natural (including formally managed ecosystems

The current study investigates attitudes toward one form of sex for resources: the so-called sugar relationships, which often involve exchanges of resources for sex and/or companionship. The present study examined associations among attitudes toward sugar relationships and relevant variables (e.g., sex, sociosexuality, gender inequality, parasitic exposure) in 69,924 participants across 87 countri

OBJECTIVES: To investigate whether the relative effectiveness of janus kinase inhibitors (JAKis) versus tumour necrosis factor inhibitors (TNFi) or other biological disease-modifying antirheumatic drugs in rheumatoid arthritis differ by the presence or absence of risk factors for cardiovascular (CV) disease, age, sex and smoking. METHODS: Through Swedish registers, we identified 13 493 individuals

In this Letter, we manipulate the phase shift of a Josephson junction using a parallel double quantum dot (QD). By employing a superconducting quantum interference device, we determine how orbital hybridization and detuning affect the current-phase relation in the Coulomb blockade regime. For weak hybridization between the QDs, we find π junction characteristics if at least one QD has an unpaired

Higher education institutions (HEIs) can play a key role in the transition to the circular economy (CE) given their missions, characteristics and role in shaping the coming generations of citizens and leaders. The aim of this paper is to provide a comprehensive examination of HEIs as microcosms for transitioning to circular models. Through a semi-systematic literature review, it focuses on the sys

The gender patenting gap is well-established and is wide. Despite important progress made over the past decades, the gap remains. Why are women underrepresented in patenting activities? What are the roots of the gender patenting gap? How did the gap evolve since the ‘modern’ patenting system was established? Our knowledge of women’s contribution to innovative activities in the past is extremely sc

It is a well-known fact that when we in Korea find elaborate polite conjugations, that structure and determine everyday interaction, the Danes, on the other side of the Globe, have a habit of saying ‘you’ (‘du’) in almost every context. We are dealing with an Asian language ruled by a high level of honorific phrases and a Scandinavian language characterized by its more unpolished and straightforwa

Playing outdoors in nature with peers has been attributed most importance for children's healthy development but is increasingly marginalized because of the attractiveness of screen-based play. Careful merging of digital technology into outdoor play environments rich on nature elements could potentially help bridge digital play with more traditional play activities outdoors. A systematic compariso
