Co-adsorption of p-mercaptobenzoic acid on silver nanoparticles enhances the plasmon-mediated coupling reaction of p-ethynylaniline

The enhancement of the electromagnetic field elicited by localized surface plasmon resonance (LSPR) is conducive to the generation of charge carriers, which have an important effect in driving many kinds of chemical reactions. Nonetheless, the short lifespan of charge carriers generated by plasmon (typically femtoseconds to nanoseconds) limits their effectiveness in promoting chemical reactions. H

Direct Imaging of Nanoscale Ferroelectric Domains and Polarization Reversal in Ferroelectric Capacitors

Ferroelectric thin films present a powerful platform for next-generation computing and memory applications. However, domain morphology and dynamics in buried ferroelectric stacks have remained underexplored, despite their importance for real device performance. Here, nanoprobe X-ray diffraction (nano-XRD) is used to image ferroelectric domains inside BiFeO3-based capacitors, revealing local disord

AI-Enhanced High-Resolution Functional Imaging Reveals Trap States and Charge Carrier Recombination Pathways in Perovskite

Understanding and managing charge carrier recombination dynamics is crucial for optimizing the performance of metal halide perovskite optoelectronic devices. In this work, we introduce a machine learning-assisted intensity-modulated two-photon photoluminescence microscopy approach for quantitatively mapping recombination processes in MAPbBr3 perovskite microcrystalline films at micrometer-scale re

Dual conformational emission and vibrational coherence in a sulfone-embedded narrowband emitter

Organic luminescent narrowband emitters have emerged as promising candidates for wide-color-gamut displays. However, the comprehensive photo-induced structural and vibrational dynamics responsible for the spectral broadening remain poorly understood. In this study, ultrafast spectroscopy is employed to elucidate the excited state dynamics of a sulfone-embedded narrowband emitter, 2tCPD. An intrins

The visual system of a nocturnal long-distance migrant, the Australian Bogong moth

The Australian Bogong moth (Agrotis infusa) is a small noctuid moth that undertakes annual, nocturnal migrations of up to 1000 km to escape the summer heat of its breeding grounds. The moths travel to cool alpine caves, where they enter a dormant state (aestivation) before returning to reproduce and die. During migration, their brains integrate magnetic and visual cues to guide their flight direct

Improving the Sales Process Efficiency Without Jeopardizing Technical Risks

Since recently, Vestas Northern Europe has been facing a buyers’ market with more demanding customers than before. In addition, a rapid growth and a restrictive risk policy have caused inefficiency within the organization. The purpose is to investigate how the efficiency in the sales phase can be increased in advantage for additional projects to be handled. The efficiency is to be increased withou

Bone Scan Index as a prognostic imaging biomarker during androgen deprivation therapy.

Bone Scan Index (BSI) is a quantitative measurement of tumour burden in the skeleton calculated from bone scan images. When analysed at the time of diagnosis, it has been shown to provide prognostic information on survival in men with metastatic prostate cancer (PCa). In this study, we evaluated the prognostic value of BSI during androgen deprivation therapy (ADT).

The new songs of praise: Text, music and performance from a Swedish perspective

In our contemporary age, the name praise song has got a special meaning, roughly defined as: a song consisting of a rather short text that is sung over and over again, set to music in some contemporary popular style, directed by a worship leader, and accompanied by a team with instruments that may be unusual in church, as el-guitars and drums. The phenomenon is described and critically evaluated.

Matching Parton Showers and Matrix Elements

We compare different procedures for combining fixed-order tree-level matrix element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW scheme and one based on the so-called MLM scheme using different matrix element generators and different parton cascades. We find that although similar results are o

Professional desire, competence and engagement in IS context

This paper attempts to address the failings of a predominant paradigm in IS research and practice that emphasises technological determinism. This paradigm makes use of a false belief in the power of rationality in organizational decision-making, and a mythology in which organizational actors can be viewed as passive ‘users’ of technology. We wish to create a discussion of the nature and role of pr

From Bugs to Decision Support – Leveraging Historical Issue Reports in Software Evolution

Popular Abstract in Swedish Utvecklare i stora mjukvaruprojekt måste orientera sig i enorma informationslandskap. Brist på överblick innebär ett hårt slag mot produktiviteten. Mönster ifrån tidigare buggar kan guida framtida underhållsarbete.Software developers in large projects work in complex information landscapes and staying on top of all relevant software artifacts is an acknowledged challenge. As software systems often evolve over many years, a large number of issue reports is typically managed during the lifetime of a system, representing the units of work needed for its improvement, e.g., defects to fix, requested features, or

Imatinib after induction for treatment of children and adolescents with Philadelphia-chromosome-positive acute lymphoblastic leukaemia (EsPhALL): a randomised, open-label, intergroup study

Background Trials of imatinib have provided evidence of activity in adults with Philadelphia-chromosome-positive acute lymphoblastic leukaemia (ALL), but the drug's role when given with multidrug chemotherapy to children is unknown. This study assesses the safety and efficacy of oral imatinib in association with a Berlin-Frankfurt-Munster intensive chemotherapy regimen and allo geneic stem-cell tr

Local dependencies and Poissonification: a case study

Traffic characterization is of great importance in the analysis and dimensioning of modem telecommunication networks. In this paper, the microdynamics of some sets of traffic are investigated. The approach we use to study the microdynamics is Poissonification, which is away of transforming a point process into a Poisson process locally. We want to gain basic knowledge of how the traffic behaves on

Inclusion Through Design - Engaging Children with Disabilities in Development of Multi-Sensory Environments

This paper is based on outcomes from SID (http://sid.desiign.org), a three-year project where twenty-four children with profound intellectual disabilities visited three MSE centres. SID's aim was to develop and demonstrate the potentials of interactive design in and for MSE practices together with the children and the pedagogical staff. In the project, we developed artefacts that were designed to
