The Swedish particle så is attested in different usages. In one of these, så introducesassertive clauses forming the foreground, or the skeleton, of a narrative. It is argued that, ifthe distribution of this particular particle is to be captured in a theory of syntax, such atheory needs to incorporate notions relating to narrative discourse or, in other words, atheory in which grammatical statemen
IMPORTANCE: Life expectancy is a composite health measure reflecting acute and life-course exposures. Identifying conditions behind disparities in life expectancy can guide policy, planning, and financing to battle the most urgent health problems.OBJECTIVE: To examine the contribution of 33 causes of death to life expectancy disparities, highlighting 2 sets of priority conditions-8 infectious and
Objective: The antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides are heterogeneous disorders. The aim of this study was to identify and characterize subgroups of patients based on sex, ANCA, age at diagnosis, and organ involvement. Methods: In total, 1,167 patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) were retrospectively recruited to the s
PURPOSE: Early identification of the underlying cause of intracerebral hemorrhage (ICH) is important for treatment and prognosis. This study aims to investigate the association of hematoma volume and other clinical parameters on the distribution of cerebral amyloid angiopathy (CAA) probability according to the simplified Edinburgh CT criteria in a large, unselected intracerebral hemorrhage (ICH) p
In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain. In this paper, we study an implementation of Maxwell's demon that can operate in both domains. In particular, we investigate information-to-work conversion over the quantum-to-classica
BackgroundComorbidity burden may affect the outcome following endovascular thrombectomy (EVT) for medium‐vessel occlusions. Since patients with high comorbidity burden are likely to be underrepresented in trials on EVT for medium‐vessel occlusions, observational data are needed to assess the benefit of EVT for these patients.MethodsWe conducted an observational study on all prestroke independent p
Objective: Following the favorable outcomes demonstrated by the Early MiNimally-invasive Removal of IntraCerebral Hemorrhage (ENRICH) trial in supratentorial intracerebral hemorrhage (ICH) patients treated with minimally invasive surgery (MIS), and considering the increasing interest in MIS, we aimed to assess the potential eligibility rate for ICH patients in Sweden. Methods: All patients with sp
This book examines how caseworkers are governed in today’s street-level bureaucracies. It redefines our understanding of public sector governance by highlighting the subtle, informal, and everyday forms of organizational governance that shape caseworkers’ subjectivities beyond formal policies and professional identities. Based on four distinct types of normative governance – ‘governance by discour
BackgroundEarly initiation of breastfeeding, defined as breastfeeding within one hour of birth, halves the risk of neonatal mortality, establishing it as a crucial outcome component in various interventions implemented across South Asian countries. However, the overall effect of these interventions remain unexamined. Therefore, this study seeks to address this knowledge gap by evaluating the overa
The structural evolution of molecular hydrogen H2 under multi-megabar compression and its relation to atomic metallic hydrogen is a key unsolved problem in condensed-matter physics. Although dozens of crystal structures have been proposed by theory1, 2, 3–4, only one, the simple hexagonal-close-packed (hcp) structure of only spherical disordered H2, has been previously confirmed in experiments5. T
Electrons photoemitted by extreme ultraviolet attosecond pulses derive spatially from the first few atomic surface layers and energetically from the valence band and highest atomic orbitals. As a result, it is possible to probe the emission dynamics from a narrow 2D region in the presence of optical fields, as well as obtain elemental specific information. However, combining this with spatially-re
Within the FLASH2020+ upgrade, the pump-probe laser capabilities of the extreme ultraviolet and soft x-ray free-electron laser (XFEL) FLASH in Hamburg will be extended. In particular, providing wavelength tunability, shorter pulse durations, and reduced arrival time jitter will increase the scientific opportunities and the time resolution for the XFEL-optical laser pump-probe experiments. We prese
A novel regularization method for shape optimization of contacting structures is proposed. The shape optimization avoids parameterizations via splines or the level set method by directly optimizing the nodes in the finite element mesh. In the past this approach was limited by numerical difficulties arising from mesh entanglement and serrated boundaries but recent advances in regularization techniq
Attosecond pulses, produced through high-order harmonic generation in gases, have been successfully used for observing ultrafast, subfemtosecond electron dynamics in atoms, molecules and solid state systems. Today’s typical attosecond sources, however, are often impaired by their low repetition rate and the resulting insufficient statistics, especially when the number of detectable events per shot
The frequency modulation transfer property of a backward-wave optical parametric oscillator (BWOPO) is investigated in the context of near-IR pulse compression. The maximum transferrable bandwidth from the pump to the forward wave in a BWOPO is determined by the group dispersion mismatch. In comparison, the third-order phase introduced in a single-grating compressor setup is more detrimental to ac
The strict momentum conservation constraints for backward-wave optical parametric oscillators (BWOPOs) gives an inherently narrowband backward-generated wave, even with broadband pumping. Unfortunately, the limited tuning range of this wave restricts potential applications. Here we demonstrate a method to circumvent this restriction and increase the tuning range by more than one order of magnitude
Mirrorless optical parametric oscillators (MOPOs) are very attractive parametric devices that rely on the nonlinear interaction of counter-propagating photons to inherently establish distributed feedback, without the use of external mirrors or surface coatings. These devices offer unique spectral and coherence properties that will benefit a large variety of applications ranging from spectroscopy t
Strongly enhanced backward stimulated polariton scattering (BSPS) is demonstrated in periodically-poled KTiOPO4 (KTP) crystals with a high power-conversion efficiency up to 70%. We study the physical mechanism of such counter-propagating parametric interaction with phonon-polaritons in χ(2) modulated structures. BSPS is a three-wave mixing that is distinguished from backward stimulated Raman scatt
