In the era of precision medicine, analyzing the transcriptomic profile of patients is essential to tailor the appropriate therapy. In this study, we explored transcriptional differences between two invasive breast cancer s...
Neural correlates of metacontrast masking across different contrast polarities
Aydın, Alaz; Ogmen, Haluk; Kafaligonul, Hulusi (2021-03-01)
Metacontrast masking is a powerful illusion to investigate the dynamics of perceptual processing and to control conscious visual perception. However, the neural mechanisms underlying this fundamental investigative tool are...
Multi-year vector dynamic time warping-based crop mapping
Teke, Mustafa; Çetin, Yasemin (2021-03-01)
Recent automated crop mapping via supervised learning-based methods have demonstrated unprecedented improvement over classical techniques. Classification accuracies of these methods degrade considerably in cross-year mappi...
Diffusion Tensor Imaging Group Analysis Using Tract Profiling and Directional Statistics
Metin, Mehmet Ozer; Gökçay, Didem (2021-03-01)
Group analysis in diffusion tensor imaging is challenging. Comparisons of tensor morphology across groups have typically been performed on scalar measures of diffusivity, such as fractional anisotropy (FA), disregarding th...
Spherical harmonics based acoustic scene analysis for object-based audio
Çöteli, Mert Burkay; Hacıhabiboğlu, Hüseyin; Department of Information Systems (2021-2-19)
Object-based audio relies on elemental audio signals from individual sound sources and their associated metadata to be reconstructed at the listener side. While defining audio objects in a production setting is straightfor...
