This study succeeded to prepare three pure phases of Mn2O3, Mn3O4 beside one of the best cathode materials, spinel LiMn2O4. LiMn2O4 with high phase purity and crystallinity was synthesized by a facile, cost effective and one step synthesis method. The structure and morphology of the powders were studied in detail by means of X-ray diffraction (XRD), thermogravimetric analysis (TGA), field emission
Understanding monthly runoff variability, its spatio-temporal characteristics, and key drivers under climate change and human impacts is crucial for long-term water resource management. However, current knowledge remains limited, especially in high-elevation, seasonally cold regions. Focusing on 10 sub-basins along an elevation gradient (1000 to 5900 ma.s.l.) in the hydrologically complex Yalong R
We describe development and application of the CH3 photo-fragmentation laser-induced fluorescence (PF-LIF) diagnostic whereby CH is created and then detected. Specifically, we employed sum-frequency generation to produce 5th-harmonic output from a Nd:YAG laser (λ = 212.8 nm) for photolyzing CH3. The residual 2nd-harmonic beam was then used to pump a dye laser, the output of which was frequency-dou
This article investigates how older citizens perceive and utilise digital health technologies as part of their everyday health management, health-related risk monitoring and illness prevention. This study draws on empirical data collected as part of the HAIDI research project and include interviews and media go-alongs with 71 individuals aged 75–100 years living in Sweden, Finland and Denmark. Int
Improving accuracy and timeliness for osteoporosis diagnosis could help prevent fragility fractures, morbidity, and mortality for older individuals. Osteoporosis is an often silent health condition, especially as regards vertebral fractures, and WHO issued a call to action for primary care to lead efforts in screening, assessing, and managing diseases such as osteoporosis. We used a machine learni
Evidence on the predictive ability of risk assessment models for event-free survival (EFS) in patients with pulmonary arterial hypertension is scarce. We aimed to investigate the relationship between risk status at 6 months after diagnosis (6 M) and EFS, by three risk models: Multicomponent Improvement (MCI), ESC/ERS 4-Strata Risk (4SR), and noninvasive French PH Registry Score (FRS). Data collect
The bar pattern speed of the Large Magellanic Cloud (LMC) has been measured using Gaia data, suggesting the presence of a slow pattern that is perhaps not rotating at all. Numerical simulations of interacting LMC-SMC systems were able to reproduce a bar stoppage. Here, we report on the first measurement of the bar pattern speed of the LMC as a function of the evolutionary phase of its stellar popu
Long- and short-range correlations for pairs of charged particles are studied via two-particle angular correlations in pp collisions at s = 13 TeV and p–Pb collisions at sNN = 5.02 TeV. The correlation functions are measured as a function of relative azimuthal angle ∆φ and pseudorapidity separation ∆η for pairs of primary charged particles within the pseudorapidity interval |η| < 0.9 and the trans
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed using the Large Hadron Collider proton-proton collision data sample at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector that correspo
A combination of searches for new heavy spin-1 resonances decaying into different pairings of W, Z, or Higgs bosons, as well as directly into leptons or quarks, is presented. The data sample used corresponds to 139 fb−1 of proton-proton collisions at s = 13 TeV collected during 2015–2018 with the ATLAS detector at the CERN Large Hadron Collider. Analyses selecting quark pairs (qq, bb, tt¯, and tb)
This paper presents the measurement of fiducial and differential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of s = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge
I Sverige förekommer flera olika journalsystem inom sjukvården, vilket innebär att journalanteckningar ser olika ut beroende på vilket journalsystem som används. Strukturen hos journalanteckningarna skiljer sig till viss del åt. I denna artikel undersöks hur strukturen ser ut i olika journalsystem och hur journalanteckningarnas delar benämns. Sammantaget råder det på ett övergripande plan ingen en
Policymaking around educational technology (ed-tech) is increasingly influenced by networks of public and private actors ranging from Big Tech corporations and international organisations through to ed-tech evidence brokers and consultants. This paper considers a relatively unexplored facet of contemporary ed-tech policy work – public-facing (ex)teachers advocating for technological change through
Manganese tetra-pyridyl-porphyrins are found to self-organize in an ordered monolayer on graphene. Moreover, post deposition of cobalt ad-atoms steers the geometric reordering of the layer, yielding the formation of a self-assembled bimetallic network, where both Mn and Co are tetra-coordinated with nitrogen. While manganese shifts from Mn(ii) towards the +2/+3 oxidation state range, depending on
Ecologists have long proposed that environments providing more energy can support more species, yet empirical evidence frequently contradicts this expectation. We argue that such inconsistencies result from confounding geographical influences that mask the true relationship between species richness and energy-related factors. Here, by comparing species richness across different climate conditions,
Background: The optimal timing of oral anticoagulation for prevention of early ischaemic stroke recurrence in people with acute ischaemic stroke and atrial fibrillation remains uncertain. We aimed to estimate the effects of starting a direct oral anticoagulant (DOAC) early (≤4 days) versus later (≥5 days) after onset of ischaemic stroke. Methods: For this systematic review and meta-analysis we sea
Introduction Despite an increasing amount of research related to gender-affirming treatment (GAT) outcomes among transgender and gender-diverse (TGD) people (ie, people who experience discomfort or distress in the misalignment between their gender and sex assigned at birth) in recent years, the evidence base for current recommendations is suboptimal. One contributing factor is the heterogeneity in
