Our present aim was to stratify participants of the UK Biobank cohort based on three readily measurable common independent risk factors, and to investigate depression genomics in each group to discover common and separate biological etiology. Two-step cluster analysis was run separately in males ( n = 149,879) and females ( n = 174,572), with neuroticism (a tendency to experience negative emotions), body fat percentage, and years spent in education as input variables. Genome-wide association analyses were implemented within each of the resulting clusters, for the lifetime occurrence of either a depressive episode or recurrent depressive disorder as the outcome. Variant-based, gene-based, gene set-based, and tissue-specific gene expression test were applied. Phenotypically distinct clusters with high genetic intercorrelations in depression genomics were found. A two-cluster solution was the best model in each sex with some differences including the less important role of neuroticism in males. In females, in case of a protective pattern of low neuroticism, low body fat percentage, and high level of education, depression was associated with pathways related to olfactory function. While also in females but in a risk pattern of high neuroticism, high body fat percentage, and less years spent in education, depression showed association with complement system genes. Our results, on one hand, indicate that alteration of olfactory pathways, that can be paralleled to the well-known rodent depression models of olfactory bulbectomy, might be a novel target towards precision psychiatry in females with less other risk factors for depression. On the other hand, our results in multi-risk females may provide a special case of immunometabolic depression.}, year = {2024}, eissn = {2158-3188}, orcid-numbers = {Eszlári, Nóra/0000-0003-4913-028X; Hullám, Gábor István/0000-0002-4765-2351; Gál, Zsófia/0000-0002-9441-1497; Török, Dóra/0000-0001-9213-4345; Nagy, Tamás/0000-0002-0137-4341; Baksa, Dániel/0000-0002-7826-9179; Gonda, Xénia/0000-0001-9015-4203; Bagdy, György/0000-0001-8141-3410; Juhász, Gabriella/0000-0002-5975-4267} } @article{MTMT:34768972, title = {ConcurrentWitness2Test: Test-Harnessing the Power of Concurrency (Competition Contribution)}, url = {https://m2.mtmt.hu/api/publication/34768972}, author = {Bajczi, Levente and Ádám, Zsófia and Micskei, Zoltán Imre}, doi = {10.1007/978-3-031-57256-2_16}, journal-iso = {LNCS}, journal = {LECTURE NOTES IN COMPUTER SCIENCE}, volume = {14572}, unique-id = {34768972}, issn = {0302-9743}, abstract = {ConcurrentWitness2Test is a violation witness validator for concurrent software.

Computational methods, particularly drug-target interaction prediction, have emerged as efficient tools, yet the explainability of machine learning models remains a challenge. Our work aims to provide more interpretable interaction prediction models using similarity-based prediction in a latent space aligned to biological hierarchies. We investigated integrating drug and protein hierarchies into a joint-embedding drug-target latent space via embedding regularization by conducting a comparative analysis between models employing traditional flat Euclidean vector spaces and those utilizing hyperbolic embeddings. Besides, we provided a latent space analysis as an example to show how we can gain visual insights into the trained model with the help of dimensionality reduction. Our results demonstrate that hierarchy regularization improves interpretability without compromising predictive performance. Furthermore, integrating hyperbolic embeddings, coupled with regularization, enhances the quality of the embedded hierarchy trees. Our approach enables a more informed and insightful application of interaction prediction models in drug discovery by constructing an interpretable hyperbolic latent space, simultaneously incorporating drug and target hierarchies and pairing them with available interaction information. Moreover, compatible with pairwise methods, the approach allows for additional transparency through existing explainable AI solutions.}, year = {2024}, eissn = {1932-6203}, orcid-numbers = {Pogány, Domonkos/0000-0003-4968-7504; Antal, Péter/0000-0002-4370-2198} } @article{MTMT:34727894, title = {Application of Mutation testing in Safety-Critical Embedded Systems: A Case Study}, url = {https://m2.mtmt.hu/api/publication/34727894}, author = {Serban, Andrada Alexia and Micskei, Zoltán Imre}, doi = {10.12700/APH.21.8.2024.8.5}, journal-iso = {ACTA POLYTECH HUNG}, journal = {ACTA POLYTECHNICA HUNGARICA}, volume = {21}, unique-id = {34727894}, issn = {1785-8860}, year = {2024}, eissn = {1785-8860}, pages = {87-106}, orcid-numbers = {Micskei, Zoltán Imre/0000-0003-1846-261X} } @misc{MTMT:34726765, title = {Design Optimization of a Current Sensing Trace with respect to Skin Effect by FEM Simulations}, url = {https://m2.mtmt.hu/api/publication/34726765}, author = {Ákos, Ferenc Hegedűs and Dabóczi, Tamás}, unique-id = {34726765}, year = {2024}, orcid-numbers = {Dabóczi, Tamás/0000-0002-7371-2186} } @article{MTMT:34720081, title = {Analysis of Quantization Noise in Fixed-Point HDFT Algorithms}, url = {https://m2.mtmt.hu/api/publication/34720081}, author = {Alrwashdeh, Monther and Czifra, Balazs and Kollár, Zsolt}, doi = {10.1109/LSP.2024.3372782}, journal-iso = {IEEE SIGNAL PROC LET}, journal = {IEEE SIGNAL PROCESSING LETTERS}, volume = {31}, unique-id = {34720081}, issn = {1070-9908}, abstract = {The Discrete Fourier Transform (DFT) algorithm is widely used in signal processing and communication systems to transform the signal to the frequency-domain.

One Sliding DFT (SDFT) method is the Hopping DFT (HDFT), where the DFT calculations are not evaluated sample-by-sample but with longer steps, thus further reducing the computational complexity compared to the other SDFT algorithms. This letter analyses the effect of fixed-point roundoff error in the HDFT algorithm, including the Updating Vector Transform (UVT) block. A closed-form expression for the resulting quantization noise power at the output of the HDFT algorithm is provided, which is validated through simulations.

In this architecture, the constant increase in size and the demand to decrease bit precision are two factors that contribute to the significant enlargement of quantization errors. We introduce an analytical tool that models the propagation of Quantization Noise Power (QNP) in floating-point MLP ANNs. Contrary to the state-of-the-art approach, which compares the exact and quantized data experimentally, the proposed algorithm can predict the QNP theoretically when the effect of operation quantization and Coefficient Quantization Error (CQE) are considered. This supports decisions in determining the required precision during the hardware design. The algorithm is flexible in handling MLP ANNs of user-defined parameters, such as size and type of activation function. Additionally, a simulation environment is built that can perform each operation on an adjustable bit precision. The accuracy of the QNP calculation is verified with two publicly available benchmarked datasets, using the default precision simulation environment as a reference. © The Author(s) 2024.}, year = {2024}, eissn = {1939-8115}, orcid-numbers = {Renczes, Balázs/0000-0003-4259-5172} } @CONFERENCE{MTMT:34714453, title = {Calibrated Sinefit Based on Quantized Data}, url = {https://m2.mtmt.hu/api/publication/34714453}, author = {Paolo, Carbone and Renczes, Balázs and Alessio, De Angelis and Antonio, Moschitta}, booktitle = {Proceedings of the IEEE I2MTC conference}, unique-id = {34714453}, year = {2024}, orcid-numbers = {Renczes, Balázs/0000-0003-4259-5172} }
