Automatic Detection Of Depression Using A Cnn-Transformer Model Based On Low-Channel Eeg Data, Dongfang Yu, Penghai Li, Fei Su, Kun Wang, Shutong Duan, Ding Yuan

Turkish Journal of Electrical Engineering and Computer Sciences

Background: Accurate and portable diagnostic tools for Major Depressive Disorder (MDD) remain a critical unmet need in clinical practice. Electroencephalography (EEG), with its noninvasiveness and high sensitivity, presents an ideal modality, yet traditional multi-channel EEG systems limit clinical convenience and practical deployment. Methods: We developed a novel CNN-Transformer hybrid model using only eight EEG channels selected from frontal regions to detect MDD. Minimal preprocessing steps (basic filtering) were applied to EEG data before the model automatically learned both local and global signal features through convolutional and self-attention mechanisms. We validated this method through comprehensive experiments, including within-dataset and cross-dataset evaluations, …

Fractional-Order Adaptive Terminal Sliding Mode Control For Synchronization Of Uncertain Chaotic Memristive Chua's Circuit, Dorukhan Asteki̇n, Fati̇h Adigüzel

Turkish Journal of Electrical Engineering and Computer Sciences

Memristive-based chaotic dynamical systems exhibit chaotic behavior with signals of unpredictable complex ity, making it difficult to achieve full synchronization in master-slave systems. Therefore, an advanced synchronization method is required to overcome the chaotic model uncertainties and external disturbances. In this study, a fractional order terminal sliding mode synchronization is proposed for the uncertain memristive chaotic Chua’s circuit. After presenting the integer-order model of the chaotic memristive Chua’s circuit, a fractional-order sliding surface-based non linear synchronization structure, incorporating the fractional derivative operator, is designed. The convergence of the synchronization closed-loop system is proven using Lyapunov theory. To demonstrate its effectiveness …

A Combined Dld-Inar(P) Model For Overdispersed Count Data, Norbert Zongo University, Koudougou, Burkina Faso, Tegawende Martin Kabore, O. Jean-Etienne Ouedraogo

Baku Mathematical Journal

In this paper, we develop a combined order p integer-valued autoregressive process whose marginal distribution follows the discrete Lindley distribution (DLD) [1]. Referred to as the CDLD-INAR(p) process, this model is particularly suited for modeling count time series exhibiting overdispersion. Formulation of this model is based on the binomial thinning operator introduced by Steutel [8]. Several conditional theoretical properties of the process are established, and its parameters are estimated using the conditional maximum likelihood method. The asymptotic properties of the resulting estimators are also investigated. Finally, the practical relevance of the proposed model is demonstrated through an application to real …

Wavelet-Based Estimation Of Long-Memory Parameter In Stochastic Volatility Models Using A Robust Log-Periodogram, University Of Kara, Kara, Togo, Manganaw Ndaam, Tchilabalo Abozou Kpanzou, Edoh Katchekpele Sep 2025

Wavelet-Based Estimation Of Long-Memory Parameter In Stochastic Volatility Models Using A Robust Log-Periodogram, University Of Kara, Kara, Togo, Manganaw Ndaam, Tchilabalo Abozou Kpanzou, Edoh Katchekpele

Baku Mathematical Journal

In this paper, we propose a novel method for estimating the long-memory parameter in time series. By combining the multi-resolution framework of wavelets with the robustness of the least absolute deviations criterion, we introduce a periodogram providing a robust alternative to classical methods in the presence of non-Gaussian noise. Incorporating this periodogram into a log-periodogram regression, we develop a new estimator. Simulation studies demonstrate that our estimator outperforms the Geweke and PorterHudak (GPH) and wavelet-based log-periodogram (WBLP) estimators, particularly in terms of mean squared error, across various sample sizes and parameter configurations.

Modeling-Based Prediction Of Current Oscillation With The Josephson Frequency In Voltage-Biased Phase-Slip Center Filaments, Armen Gulian Sep 2025

Modeling-Based Prediction Of Current Oscillation With The Josephson Frequency In Voltage-Biased Phase-Slip Center Filaments, Armen Gulian

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this article, we demonstrate that the voltage-biased phase-slip center (PSC) can act as a direct equivalent (not merely an analogy) of the Josephson effect in Josephson junctions (JJs). We analyze the behavior of PSCs in the case when a constant voltage V is applied to the superconducting filament. The analysis is performed using finite element modeling on the basis of time-dependent Ginzburg–Landau (TDGL) equations. It reveals that the current in the filament oscillates with the Josephson frequency ω = 2eV/h. This fact may have important corollaries in practice.

Parallel Lives: Revitalization Of An Ancient Method Of Inquiry, Geoffrey Thomas Uhal Sep 2025

Parallel Lives: Revitalization Of An Ancient Method Of Inquiry, Geoffrey Thomas Uhal

Doctoral Dissertations and Projects

The Parallel Lives style examination and biography is one of the oldest forms of historical inquiry, providing a comparison between a foreign subject and a more familiar subject as a frame of reference. This style of examination was popular for dissertations in the 19th century among military historians writing about generals who were stylistically known as “Great Captains” for much of history. While the moral comparisons of such histories in bygone eras possess less utility, multimodal comparisons of lives that readers have more and less contextual background to provide a model to bridge the gap between foreign and familiar subjects. …
