  1. 16. Coarse-Grained Models of Ionic Solutions

    Författare :Ryan Szparaga; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; Classical Density Functional Theory; Coarse-Grained Models; Ionic Liquids; Prewetting; Capillary Condensation; Electric Double Layer; Differential Capacitance.;

    Sammanfattning : Room-temperature ionic liquids (RTILs) are compounds composed entirely of ions, which are liquid at temperatures below 100 degrees Celsius. Their high ionic strength and strong coupling make them useful for a number of applications, e.g. as electrolytes in supercapacitors. LÄS MER

  3. 17. Supersymmetric Gauge Theories and Matrix Models

    Författare :Rainer Heise; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; Effective field theory; Matrix model; Supersymmetric gauge theories;

    Sammanfattning : We discuss recent developments in supersymmetric field theory due to the conjecture of Dijkgraaf and Vafa relating the effective superpotential of such theories to the computation of an associated matrix model. We give a short survey of N=1 supersymmetric gauge theories and state the conjecture. LÄS MER

  4. 18. Variational Inference of Dynamic Factor Models

    Författare :Erik Spånberg; Pär Stockhammar; Gebrenegus Ghilagaber; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic factor models; variational inference; missing data; nowcasting; expectation maximization; statistik; Statistics;

    Sammanfattning : When we make difficult and crucial decisions, forecasts are powerful and important tools. For that purpose, statistical models can be our most effective aid. Ideally, these models can incorporate large sets of multifaceted data. LÄS MER

  5. 19. DIGIROP prediction models for severe retinopathy of prematurity

    Författare :Aldina Pivodic; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm birth; retinopathy of prematurity; prediction models; screening; clinical decision support tool;

    Sammanfattning : BACKGROUND: Retinopathy of prematurity (ROP), a preventable, potentially blinding eye disease, is primarily diagnosed in extremely preterm infants. Gestational age (GA) and birth weight (BW) are the most prominent risk factors. Routine ROP examinations are performed to identify the low proportion of infants who progress to needing treatment.

  7. 20. Improving Language Models Using Augmentation and Multi-Modality

    Författare :Tobias Norlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; contextual augmentation; multimodal language modeling; language models;

    Sammanfattning : Language models have become a core component in modern Natural Language Processing (NLP) as they constitute a powerful base that is easily adaptable to many language processing tasks. Part of the strength lies in their ability to embed associations representing general world knowledge. LÄS MER
