Deep learning of nonlinear development of unstable flame fronts

The purpose of this study is to investigate Machine Learning methods and their ability to learn the development of nonlinear unstable flame fronts due to diffusive-thermal instabilities. This task is performed by first numerically computing long time-sequences of solutions to the chaotic partial differential equation named Kuramoto-Sivashinsky equation which models such instabilities in a flame fr

Cs3Cu4In2Cl13 Nanocrystals : A Perovskite-Related Structure with Inorganic Clusters at A Sites

An effort to synthesize the Cu(I) variant of a lead-free double perovskite isostructural with Cs2AgInCl6 resulted in the formation of Cs3Cu4In2Cl13 nanocrystals with an unusual structure, as revealed by single-nanocrystal three-dimensional electron diffraction. These nanocrystals adopt a A2BX6 structure (K2PtCl6 type, termed vacancy ordered perovskite) with tetrahedrally coordinated Cu(I) ions. In

Purification of Oleylamine for Materials Synthesis and Spectroscopic Diagnostics for trans Isomers

Oleylamine is widely used in nanomaterial and metal-halide perovskite synthesis. Impurities in commercially available oleylamine reagents are identified, purification procedures are explained, beneficial effects on lead chloride/oleylamine mixtures are documented, and impacts on materials synthesis are discussed. Suspensions of 0.12 mole fraction PbCl2 , PbBr2 , and PbI2 in purified, dried, and f

Investigation into the Photoluminescence Red Shift in Cesium Lead Bromide Nanocrystal Superlattices

The formation of cesium lead bromide (CsPbBr3 ) nanocrystal superlattices (NC SLs) is accompanied by a red shift in the NC photoluminescence (PL). The values of the PL red shift reported in the literature range from none to 100 meV without unifying explanation of the differences. Using a combination of confocal PL microcopy and steady-state optical spectroscopies we found that an overall PL red s

Impact of human foraging on tree diversity, composition, and abundance in a tropical rainforest

Tropical forest tree communities are structured by a range of large-scale drivers including elevation, certain high-impact anthropogenic activities (e.g., deforestation), and fires. However, low-impact human activities such as foraging may also be subtly but notably altering the composition of tropical forest tree communities. The study assessed the (i) differences in species diversity, patterns o

Aortic size predicts aortic dissection in Turner syndrome - A 25-year prospective cohort study

Background: Women with Turner syndrome (TS) have an increased risk of aortic dissection. The current recommended cutoff to prevent aortic dissection in TS is an aortic size index (ASI) of ≥2.5 cm/m2. This study estimated which aortic size had the best predictive value for the risk of aortic dissection, and whether adjusting for body size improved risk prediction. Methods: A prospective, observatio

Linking microenvironment modification to species interactions and demography in an alpine plant community

Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co-occurring alpine plants, we 1) determined the extent of species-specific microclimate modification by comparing temperature and soil moisture between vegetated

A multi-step predictive model for the release and transformation of K-Cl-S-containing species from biomass

The release of inorganic elements, especially K, Cl, and S, can cause severe damage to biomass conversion devices, such as slagging, fouling, or corrosion. A predictive model for the release of K-Cl-S elements can be used to enhance the design and operating conditions of biomass conversion devices. In this study, a detailed model is developed that includes 12 solid species and 13 reactions, which

Going towards a ‘perfect’ life : A qualitative study on urban middle-class young married women’s experiences and prospects on marriage life in China

The self-evident contradictory governance ideology of the Chinese Communist Party leads to urban-born young middle-class Chinese women struggling between seeking one’s own path with the discourse of ‘individualism’ under the neoliberal market economy and conforming to the traditional role in the family of patriarchal culture. This is reflected in the increasing prominent phenomena of getting marri

Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. Martinet (Martinet 1974), where he proved that there should be a dearth of stars with zero angular momenta in the solar neigh

Signal-to-noise ratio optimization in X-ray fluorescence spectrometry for chromium contamination analysis

In most cases, direct X-ray fluorescence (XRF) analysis of solutions entails technical difficulties due to a high X-ray scattering background resulting in a spectrum with a poor signal-to-noise ratio (SNR). Key factors that determine the sensitivity of the method are the energy resolution of the detector and the amount of scattered radiation in the energy range of interest. Limiting the width of t

Long-Term Functional Outcome and Quality of Life After Surgical Evacuation of Spontaneous Supratentorial Intracerebral Hemorrhage : Results from a Swedish Nationwide Cohort

Objective: To investigate long-term survival, neurologic outcome, and quality of life in patients with spontaneous supratentorial intracerebral hemorrhage (ICH) treated with craniotomy and hematoma evacuation. Methods: A nationwide multicenter retrospective analysis of 341 patients who underwent craniotomy and evacuation of supratentorial ICH between January 1, 2011, and December 31, 2015, was per

Transmedial storyworlds

Sherlock Holmes has travelled across media borders extensively: from technical to technical medium, from basic to basic medium, and from qualified to qualified medium. Through the decades, Sherlock Holmes appeared in many different forms of storytelling and media constellations, so we can analyse the character in terms of transmediality. This chapter discusses one such example: Penny Dreadful, whi

Plattformsarbetare och sjukpenninggrundande inkomst - lika, men ändå olika?

Denna artikel diskuterar frågan om hur sjukpenninggrundande inkomst bestäms i relation till plattformsarbetare och potentiella konsekvenser eller behov av förändringar till följd av det föreslagna plattformsdirektivet. Artikeln syftar till att belysa hur förändringar inom arbetsrättenockså kan medföra indirekta konsekvenser inom socialförsäkringsrätten. I artikeln diskuteras det föreslagna plattfo

Spectromicroscopic determinations of chemical environments of Ni in MoS2-Ag-Ni ternary systems

Using heterogeneous photocatalysts for harvesting sunlight and converting it for water remediation and splitting are promising to mitigate the possible crisis of environment and energy. Among various composites, the MoS2-based heterostructures and Ni-based systems exhibit unique electronic, optical properties and redox capabilities, enabling their roles as photocatalysts. Herein, the impacts of ch

How does age affect outcomes after left ventricular assist device implantation : results from the PCHF-VAD registry

Aims: Use of left ventricular assist devices (LVADs) in older patients has increased, and assessing outcomes in older LVAD recipients is important. Therefore, this study aimed to investigate associations between age and outcomes after continuous-flow LVAD (cf-LVAD) implantation. Methods and results: Cf-LVAD patients from the multicentre European PCHF-VAD registry were included and categorized into
