Assessing generalisability of deep learning-based polyp detection and segmentation methods through a computer vision challenge Ali, Sharib; et. al. (2024-12-01) Polyps are well-known cancer precursors identified by colonoscopy. However, variability in their size, appearance, and location makes the detection of polyps challenging. Moreover, colonoscopy surveillance and removal of p...
FPGA-friendly compact and efficient AES-like 8 × 8 S-box Malal, Ahmet; Tezcan, Cihangir (2024-03-01) One of the main layers in the Advanced Encryption Standard (AES) is the substitution layer, where an 8 × 8 S-Box is used 16 times. The substitution layer provides confusion and makes the algorithm resistant to cryptanalysi...
An integrative framework for clinical diagnosis and knowledge discovery from exome sequencing data Shojaei, Mona; Mohammadvand, Navid; DOĞAN, TUNCA; Alkan, Can; Çetin Atalay, Rengül; Acar, Aybar Can (2024-02-01) Non-silent single nucleotide genetic variants, like nonsense changes and insertion-deletion variants, that affect protein function and length substantially are prevalent and are frequently misclassified. The low sensitivit...
Abnormally low sensorimotor α band nonlinearity serves as an effective EEG biomarker of Parkinson’s disease Özkurt, Tolga Esat (2024-02-01) Biomarkers obtained from the neurophysiological signals of patients with Parkinson’s disease (PD) have objective value in assessing their motor condition for effective diagnosis, monitoring, and clinical intervention. Prom...
BioNet-XR: Biological Network Visualization Framework for Virtual Reality and Mixed Reality Environments Şenderin, Büşra; Tunçbağ, Nurcan; Sürer, Elif (2024-02-01) Protein-protein interaction networks (PPIN) enable the study of cellular processes in organisms. Visualizing PPINs in extended reality (XR), including virtual reality (VR) and mixed reality (MR), is crucial for exploring s...
Spatiotemporal signal space separation for regions of interest: Application for extracting neuromagnetic responses evoked by deep brain stimulation Oswal, Ashwini; Abdi-Sargezeh, Bahman; Sharma, Abhinav; Özkurt, Tolga Esat; Taulu, Samu; Sarangmat, Nagaraja; Green, Alexander L.; Litvak, Vladimir (2024-02-01) Magnetoencephalography (MEG) recordings are often contaminated by interference that can exceed the amplitude of physiological brain activity by several orders of magnitude. Furthermore, the activity of interference sources...
A Modular Serious Game Development Framework for Virtual Laboratory Courses Yucel, Furkan; Sultan Unal, Hasret; Sürer, Elif; Huvaj Sarıhan, Nejan (2024-01-01) Laboratory experience is an integral part of the undergraduate curriculum in most engineering courses. When physical learning is not feasible, and when the demand cannot be met through actual hands-on laboratory sessions, ...
Quasi-Newton FDE in One-Bit Pseudo-Randomly Quantized Massive MIMO-OFDM Systems Yılmaz, Gökçen; Yılmaz, Ali Özgür (2024-01-01) This letter offers a new frequency-domain equalization (FDE) scheme that can work with a pseudo-random quantization (PRQ) scheme utilizing non-zero threshold quantization in one-bit uplink multi-user massive multiple-input...
Design, synthesis, molecular docking studies and biological evaluation of thiazole carboxamide derivatives as COX inhibitors Hawash, Mohammed; Jaradat, Nidal; Abualhasan, Murad; ŞÜKÜROĞLU, MURAT KADİR; Qaoud, Mohammed T.; Kahraman, Deniz Cansen; Daraghmeh, Heba; Maslamani, Leen; Sawafta, Mais; Ratrout, Ala; Issa, Linda (2023-12-01) Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been the most commonly used class of medications worldwide for the last three decades. Objectives: This study aimed to design and synthesize a novel series of ...
Pan-cancer clinical impact of latent drivers from double mutations Yavuz, Bengi Ruken; Tsai, Chung-Jung; Nussinov, Ruth; Tuncbag, Nurcan (2023-12-01) Here, we discover potential ‘latent driver’ mutations in cancer genomes. Latent drivers have low frequencies and minor observable translational potential. As such, to date they have escaped identification. Their discovery ...
An automated framework for evaluation of deep learning models for splice site predictions Zabardast, Amin; Tamer, Elif Güney; Aydın Son, Yeşim; Yılmaz, Arif (2023-12-01) A novel framework for the automated evaluation of various deep learning-based splice site detectors is presented. The framework eliminates time-consuming development and experimenting activities for different codebases, ar...
Neurodevelopmental disorders and cancer networks share pathways, but differ in mechanisms, signaling strength, and outcome Yavuz, Bengi Ruken; Arici, M. Kaan; Demirel, Habibe Cansu; Tsai, Chung-Jung; Jang, Hyunbum; Nussinov, Ruth; Tunçbağ, Nurcan (2023-12-01) Epidemiological studies suggest that individuals with neurodevelopmental disorders (NDDs) are more prone to develop certain types of cancer. Notably, however, the case statistics can be impacted by late discovery of cancer...
sphstat: A Python package for inferential statistics on vectorial data on the unit sphere Hacıhabiboğlu, Hüseyin (2023-12-01) Data that resides on the surface of a 2-sphere is common in various scientific fields, including physics, earth sciences, astronomy, and psychoacoustics. While some tools and packages exist for performing inferential stati...
