The polarization dependence of the split two peaks in the lone-pair region in the x-ray emission spectra has been determined at several different excitation energies for both D 2O and H 2O water. In contrast to predictions based on a narrow range of local water structures where the two peaks would be of different molecular orbital symmetry and arise from, respectively, intact and dissociated molec

How should we regulate independent central banks? The Riksbank and its monetary policy toolkit .Within what boundaries are independent central banks allowed to operate? This question is seldom discussed but has gained prominence due to the changes in monetary policy since the 2008/09 financial crisis. Notably, the Swedish central bank, the Riksbank, along with other central banks, has expanded its

Disease staging, whereby the spatial extent and load of brain pathology are used to estimate the severity of Alzheimer disease (AD), is pivotal to the gold-standard neuropathological diagnosis of AD. Current in vivo diagnostic frameworks for AD are based on abnormal concentrations of amyloid-β and tau in the cerebrospinal fluid or on PET scans, and breakthroughs in molecular imaging have opened up

Background: Thyroid surgery for benign non-toxic nodular goitre is a common endocrine surgical procedure. It is not known whether thyroid hormone replacement therapy following surgery for benign thyroid disease influences mortality or morbidity rates. Methods: A retrospective observational study was conducted using national registries in Sweden. Overall mortality and morbidity rates were compared

Objectives: To investigate the cumulative incidence proportion of disseminated or local Bacillus Calmette-Guérin (BCG) infections after adjuvant BCG instillations in patients with non-muscle-invasive bladder cancer (NMIBC). Patients and Methods: We analysed the timing and occurrence of BCG infections and absolute and relative risk in relation to patient characteristics available in the Swedish nat

Purpose: The prevalence of choroidal naevi is common and has been found to be up to 10%. Little is known regarding the optical properties of choroidal naevi. A novel hyperspectral eye fundus camera was used to investigate choroidal naevi’s optical density spectra in the retina. Methods: In an ophthalmology clinic setting, patients with choroidal naevi were included in the study. Visual acuity and

Material interfaces occur at various length scales and may exhibit significantly different properties than the surrounding bulk. Motivated by their importance for electrical engineering applications such as wire bonds and electrically conductive adhesives, the focus of the present work is on material interfaces in electrical conductors. In order to approximate the physical interphase (of finite th

OBJECTIVES: It has been commonly accepted that untreated acute type A aortic dissection (ATAAD) results in an hourly mortality rate of 1–2% during the 1st 24 h after symptom onset. The data to support this statement rely solely on patients who have been denied surgical treatment after reaching surgical centres. The objective was to perform a total review of non-surgically treated (NST) ATAAD and p

In this paper we present the concept for a teleoperation system for semi-autonomous robotic boats using virtual reality. This system can be used for monitoring autonomous driving as well as for direct manual control. The integration of live sensor data is possible as well as the integration of past measurement results and their correct registration within the virtual representation. Initial field

Microbial carbon use efficiency (CUE) describes the partitioning of carbon (C) between respiration and growth, and this defines the soil-atmosphere C balance. Despite its importance, CUE is not properly represented in soil biogeochemical models. Here, we estimated how CUE varied in soil along a continental gradient. Through a structural equation model, we found that bacterial growth, fungal commun

A search for the decay of the Higgs boson to a Z boson and a light, pseudoscalar particle, a, decaying respectively to two leptons and to two photons is reported. The search uses the full LHC Run 2 proton–proton collision data at s=13 TeV, corresponding to 139 fb−1 collected by the ATLAS detector. This is one of the first searches for this specific decay mode of the Higgs boson, and it probes unex

Combining superconducting resonators and quantum dots has triggered tremendous progress in quantum information, however, attempts at coupling a resonator to even charge parity spin qubits have resulted only in weak spin-photon coupling. Here, we integrate a zincblende InAs nanowire double quantum dot with strong spin-orbit interaction in a magnetic-field resilient, high-quality resonator. The quan

Maximizing ultrafast electron-transfer kinetics in semiconductor is pivotal but challenging for high-efficiency solar-to-energy during the photocatalytic reaction process due to the intrinsic property of photocatalysts with low surface electron density. Herein, a model photocatalyst CdS@Mo is synthesized through a typical hydrothermal method for modulating the ultrafast electron-transfer to enhanc

We study stationary, periodic solutions to the thermocapillary thin-film model ∂ t h + ∂ x h 3 ∂ x 3 h − g ∂ x h + M h 2 1 + h 2 ∂ x h = 0 , t > 0 , x ∈ R , which can be derived from the Bénard-Marangoni problem via a lubrication approximation. When the Marangoni number M increases beyond a critical value M ∗ , the constant solution becomes spectrally unstable via a (conserved) long-wave instabili
