Based on WHO's data, breast cancer is one of the most deadly diseases that has claimed many victims, especially women. This disease begins with the presence of an undetected and eventually turns into malignant (cancer). This happens due to ignorance of the importance of having a medical check-up even though in good health. Doctors and researchers can prevent the development of tumor cells through treatment that begins with radiological examinations to identify the possibility of a person being affected by this disease. One of the most frequently used techniques is Mammography. This technique can detect the presence of tumor cells using advanced technology and several methods in displaying the patient's diagnostic results on low-dose X-rays in the form of mammogram images. The technology is inseparable from the methods used to identify the presence of tumor cells. In this study, we have proposed the CNN method based on the deep-CNN model to identify mammogram images in the detection of breast cancer cells with average evaluation results in terms of accuracy, precision, recall, specificity, and f-measure on mammogram image datasets of 99.52%, 99.72%, 99.31%, 99.72%, and 99.5%. These results showed that this method has a good performance in breast cancer detection. © 2023 IEEE.

IET Wireless Sensor systems 2025年第1期15卷

Stress, a common response to challenging situations, has become pervasive in contemporary daily life due to various factors. Persistent stress can weaken the human immune system, increasing the risk of chronic stress and contributing to a range of physical and mental health disorders. Therefore, timely detection of stress in its early stages is crucial for preventing adverse health outcomes. Physiological signals offer insights into the body's stress-induced changes and can be leveraged for stress detection applications. Among these signals, the photoplethysmogram (PPG) signal stands out due to its advantages. This article introduces an innovative stress detection model based on dilated convolutional neural networks (Dilated CNNs), a deep learning algorithm. This model distinguishes between an individual's stressed and non-stressed states by analysing PPG signals without requiring pre-processing, denoising, or feature extraction. Leveraging the Empatica E4 PPG signals from the Wearable Stress and Affect Detection (WESAD) dataset, the authors developed and evaluated the model, achieving remarkable results: a test accuracy of 93.56% and an area under the curve (AUC) of 96.52%. These outcomes are particularly noteworthy given the streamlined data preparation process and methodological simplicity. Beyond enabling early stress diagnosis, this advancement holds promise for enhancing overall health and well-being in the fast-paced and intricate world. Additionally, its simplicity makes it suitable for real-time stress detection and integration into wearable devices. © 2025 The Author(s).

To address the slow convergence speed of genetic algorithms (GAs) in solving the mobile robot path planning problem, this study proposes a genetic algorithm with quality of population evolution (QPEGA). In QPEGA, the population is divided into two subpopulations based on the quality of individuals, and the quality of each subpopulation is defined. The crossover and mutation probabilities of each subpopulation are dynamically adjusted to enhance the algorithm's solving quality. Additionally, the optimal parameter combination for the algorithm is determined using the orthogonal experimental method. To evaluate the performance of QPEGA, a comparison is made with standard GA and adaptive genetic algorithm (AGA). The planning results are subjected to Friedman test at a 95% confidence interval, and the experimental findings demonstrate that QPEGA outperforms the comparative algorithms and exhibits significant advantages in solving the path planning problem. © 2024 The Authors.

A single-photon source (SPS) is a device that emits individual photons sequentially. SPSs are fundamental to the progress of quantum information technologies, in which photons convey quantum information. Photons have properties such as polarization, and spatial and temporal modes, which can be used to encode quantum information.

As the world's energy demand grows and fossil fuels become increasingly burdensome, governments and stake-holders have recognized the importance of reducing carbon dioxide emissions to combat climate change. Hydrogen has been identified as a crucial component of successful decarbonization efforts. However, because hydrogen has a low density, it must typically be compressed at high pressures or liquefied in order to be transported and stored effectively. This study introduces a new method for generating compressed hydrogen, ammonia, and electricity through a multigeneration process. The process involves using a catalytic membrane reactor to recover hydrogen, while simultaneously capturing all CO2 through a membrane. The process also incorporates a high-temperature solid oxide fuel cell for efficient heat and electricity integration. Furthermore, the study presents an optimization model for the multigeneration process that helps to identify the most effective operational production patterns for generating hydrogen, ammonia, and electricity. Optimization is performed on an hourly basis for a duration of one week. According to the findings, the production of hydrogen is deemed to be the most beneficial among the three options, followed by ammonia, then electricity. © 2023 IEEE.

Training agents that are robust to environmental changes remains a significant challenge in deep reinforcement learning (RL). Unsupervised environment design (UED) has recently emerged to address this issue by generating a set of training environments tailored to the agent's capabilities. While prior works demonstrate that UED has the potential to learn a robust policy, their performance is constrained by the capabilities of the environment generation. To this end, we propose a novel UED algorithm, adversarial environment design via regret-guided diffusion models (ADD). The proposed method guides the diffusion-based environment generator with the regret of the agent to produce environments that the agent finds challenging but conducive to further improvement. By exploiting the representation power of diffusion models, ADD can directly generate adversarial environments while maintaining the diversity of training environments, enabling the agent to effectively learn a robust policy. Our experimental results demonstrate that the proposed method successfully generates an instructive curriculum of environments, outperforming UED baselines in zero-shot generalization across novel, out-of-distribution environments.
