  • Graph Drawing Contest Report 
    Kindermann, Philipp; Klute, Fabian; Mchedlidze, Tamara; Meulemans, Wouter (SpringerSpringer, 2022-01-19)
    This report describes the 29th Annual Graph Drawing Contest, held in conjunction with the 30th International Symposium on Graph Drawing and Network Visualization (GD’22) in Tokyo, Japan. Due to the continuing global COVID-19 ...
  • Microflexiblity and local integrability of horizontal curves 
    del Pino Gomez, A.; Shin, Tobias (arXiv, 2020-09-30)
    Let ξ be an analytic bracket-generating distribution. We show that the subspace of germs that are singular (in the sense of Control Theory) has infinite codimension within the space of germs of smooth curves tangent to ξ. ...
  • GCN-FFNN: A two-stream deep model for learning solution to partial differential equations 
    Bilgin, Onur; Vergutz, Thomas; Mehrkanoon, Siamak (Elsevier, 2022-10-28)
    This paper introduces a novel two-stream deep model based on graph convolutional network (GCN) architecture and feed-forward neural networks (FFNN) for learning the solution of nonlinear partial differential equations ...
  • Pushing Blocks by Sweeping Lines 
    Akitaya, Hugo; Löffler, Maarten; Viglietta, Giovanni (2022)
    We investigate the reconfiguration of $n$ blocks, or ``tokens'', in the square grid using ``line pushes''. A line push is performed from one of the four cardinal directions and pushes all tokens that are maximum in that ...
  • Black holes, quantum chaos, and the Riemann hypothesis 
    Betzios, Panos; Gaddam, Nava; Papadoulaki, Olga (arXiv, 2020-04-20)
    Quantum gravity is expected to gauge all global symmetries of effective theories, in the ultraviolet. Inspired by this expectation, we explore the consequences of gauging CPT as a quantum boundary condition in phase space. ...
  • Flipping Plane Spanning Paths 
    Aichholzer, Oswin; Knorr, Kristin; Löffler, Maarten; Masárová, Zuzana; Mulzer, Wolfgang; Obenaus, Johannes; Paul, Rosna; Vogtenhuber, Birgit (2022)
    Let S be a planar point set in general position, and let P(S) be the set of all plane (straight-line) spanning paths for S. A flip in a path P ∈ P(S) is the operation of removing an edge e ∈ P and replacing it with a new ...
  • Integrating global sustainability governance: How the Sustainable Development Goals impact institutional and policy integration at the global level 
    Bogers, Maya (Utrecht University, 2023-11-24)
    Can goals change the world? In September 2015, the United Nations (UN) unanimously adopted the 17 Sustainable Development Goals (SDGs) to "transform our world" by 2030. With these highly ambitious goals, world leaders ...
  • Structural sensitivity of the spin Hall magnetoresistance in antiferromagnetic thin films 
    Ross, Andrew; Lebrun, Romain; Ulloa, Camilo; Grave, Daniel A.; Kay, Asaf; Rothschild, Avner; Kläui, Mathias (arXiv, 2020-01-01)
    Reading the magnetic state of antiferromagnetic (AFM) thin films is key for AFM spintronic devices. We investigate the underlying physics behind the spin Hall magnetoresistance (SMR) of bilayers of platinum and insulating ...
  • Exploring Neuroscience Literature and Understanding Relations Between Brain-Related Topics - Using Augmented Reality 
    Tanhaei, Ghazaleh (Association for Computing Machinery (ACM), 2022-03-14)
    Neuroscience researchers are interested in understanding relation between anatomical regions of the brain and disorders that affect them, for example. Using the topics themselves, rather than individual articles, to examine ...
  • Visual Exploration of Neural Network Projection Stability 
    Bredius, Carlo; Tian, Zonglin; Telea, Alex (2022)
    We present a method to visually assess the stability of deep learned projections. For this, we perturb the high-dimensional data by controlled sequences and visualize the resulting changes in the 2D projection. We apply ...
  • Multimodal memory T cell profiling identifies a reduction in a polyfunctional Th17 state associated with tuberculosis progression 
    Nathan, Aparna; Beynor, Jessica I; Baglaenko, Yuriy; Suliman, Sara; Ishigaki, Kazuyoshi; Asgari, Samira; Huang, Chuan-Chin; Luo, Yang; Zhang, Zibiao; Tamara, Kattya Lopez; Jimenez, Judith; Calderon, Roger I; Lecca, Leonid; Rhijn, Ildiko van; Moody, Branch; Murray, Megan B; Raychaudhuri, Soumya (bioRxiv, 2020-04-25)
    Mycobacterium tuberculosis (M.tb) results in 10 million active tuberculosis (TB) cases and 1.5 million deaths each year, making it the world's leading infectious cause of death. Infection leads to either an asymptomatic ...
  • Empathizing with virtual agents: the effect of personification and general empathic tendencies 
    Kroes, Kim; Saccardi, Isabella; Masthoff, Judith (IEEE, 2022)
    For interactions to be natural, virtual agents should understand humans’ emotions, and humans should have emotional reactions towards them. In human-to-human interaction, this is achieved through empathic processes between ...
  • One for All, All for One: A First Step Towards Universal Access with a Social Robot 
    Pivin-Bachler, Julie; van den Broek, Egon; Gomez, Randy (IOS PressIOS Press, 2023-06)

  • Visual Cluster Separation Using High-Dimensional Sharpened Dimensionality Reduction 
    Kim, Youngjoo; Telea, Alex; Trager, Scott; Roerdink, Jos (Palgrave Macmillan Ltd., 2022)
    Applying dimensionality reduction (DR) to large, high-dimensional data sets can be challenging when distinguishing the underlying high-dimensional data clusters in a 2D projection for exploratory analysis. We address this ...
