Breast cancer is the second highest cause of cancer death among women all around the world, especially between the ages of 40 and 65. Early detection of breast cancer tumor type, benign or malignant, has remained a big challenge for physicians and radiologists. By timely identifying the tumor and knowing its type, it can allow physicians to conduct the treatment in the right direction and to take appropriate medications for that type of tumor. Therefore, it is highly important to know the type of tumor accurately to save the patient's life. This paper proposes an intelligent diagnosis method for breast cancer tumor type detection and classification based on fine needle aspirate (FNA) of a breast mass and optimized fuzzy sets. The developed method applied image processing and feature selection techniques to analyze the digitized image of a FNA. In the developed method, nine features computed from a digitized image of a FNA of a breast mass are uses as the initial input of neuro-fuzzy system. In the proposed method, we applied the Association Rules (AR) to find the most informative and effective features of the extracted features. Moreover, in order to advance the act of neuro-fuzzy system, Chaotic Bat Optimization Algorithm (CBOA) is used as learning algorithm. The proposed method is tested on Breast Cancer Wisconsin (Diagnostic) data set. The obtained numerical analysis showed that the developed diagnostic system has excellent performance and high degree of precision.

Multiuser-multiple input multiple output (MU-MIMO) systems can provide a substantial performance for cellular networks by applying direction of arrival (DOA) technique, in which the direction of sidelobe signals can be estimated. Therefore, this paper presents a different adaptive DOA algorithms where the performance of communication networks can be enhanced, in the meantime the minimizing interferences. Meanwhile, The DOA algorithm such as multi signal classification (MUSIC), minimum norm (Min-Norm), minimum variance distortionless response (MVDR) and Bartlett algorithms are studied and compared extensively regarding the estimation angles and peak power spectrum. In this regard, uniform linear array (ULA) antenna is employed to construct the weight vector for incoming sensor signals. Furthermore, this paper compares the DOA algorithms concerning the number of antenna elements as well as the incoming signal angles. The simulation results approve that the algorithms are likely have the same performance in accuracy of scanning angles. However, it is realized that all algorithms have different peak power values in order to beamwidth. Moreover, the results indicate that the DOA algorithms with the different number of antenna elements have a significant impact on a directivity and gain. Hereafter, this work can be extended to higher frequency of mmWave communication with massive number of antenna, which can meet the requirement of fifth generation (5G) network.

Femtosecond laser-induced photoexcitation of ferromagnet (FM)/heavy metal (HM) heterostructures have attracted attention by emitting broadband terahertz frequencies. The phenomenon relies on the formation of ultrafast spin current, which is largely attributed to the direct photoexcitation of the FM layer. However, we reveal that during the process, the FM layer also experiences a secondary excitation led by the hot electrons from the HM layer that travel across the FM/HM interface and transfer additional energy in the FM. Thus, the generated secondary spins enhance the total spin current formation and lead to amplified spintronic terahertz emission. The results also emphasize the significance of the secondary spin current, which even exceeds the primary spin currents when FM/HM heterostructures with thicker HM are used. An analytical model is developed to provide deeper insights into the microscopic processes within the individual layers, underlining the generalized ultrafast superdiffusive spin-transport mechanism.

ChatGPT, an AI-based chatbot, was released to provide coherent and useful replies based on analysis of large volumes of data. In this article, leading scientists, researchers and engineers discuss the transformative effects of ChatGPT on modern education. This research seeks to improve our knowledge of ChatGPT capabilities and its use in the education sector, identifying potential concerns and challenges. Our preliminary evaluation concludes that ChatGPT performed differently in each subject area including finance, coding and maths. While ChatGPT has the ability to help educators by creating instructional content, offering suggestions and acting as an online educator to learners by answering questions and promoting group work, there are clear drawbacks in its use, such as the possibility of producing inaccurate or false data and circumventing duplicate content (plagiarism) detectors where originality is essential. The often reported "hallucinations" within Generative AI in general, and also relevant for ChatGPT, can render its use of limited benefit where accuracy is essential. What ChatGPT lacks is a stochastic measure to help provide sincere and sensitive communication with its users. Academic regulations and evaluation practices used in educational institutions need to be updated, should ChatGPT be used as a tool in education. To address the transformative effects of ChatGPT on the learning environment, educating teachers and students alike about its capabilities and limitations will be crucial. © 2023, CC0.

In this study, we conducted a test with 20 sighted users to track the work described in earlier studies in an expanded scenario. As we have tried to answer whether adding multi-reference mapping of sonification to auditory graphs could improve the point estimation accuracy in nonvisual condition. We also emphasize the efficiency of the performance of multi-reference graphs using timbre to make them as efficient as mapping using a single pitch. The design of the study was different from the earlier study, who found that multi-reference mapping took a long time against single pitch mapping in auditory graphs. The results help provide empirical evidence that the multi-reference mode provides more accurate results than the single-pitch mode. The evaluation confirms that adding contexts to auditory graphs such as markers could improve the perception of auditory graphs. © 2020 IEEE.

Numerous complex situations arising from science and engineering are modeled by integral-differential equations (IDEs). Examples of these situations include mathematical modeling of infectious diseases, epidemics, circuit analysis, voltage drop equations, computational neuroscience, intergalactic modeling, and many more. To explain the mathematical structure and the behavior of various phenomena in nature, two equations with simple mathematical structure namely: the (1 + 1)-dimensional integro-differential Ito equation (IDIE) and the (2 + 1)-dimensional integro-differential Sawada-Kotera equation (IDSKE) are considered. In this analytical investigation, we have conducted an in-depth enquiry to trace the distinctive closed form progressive wave solutions of these proposed models using the ([Formula presented])-expansion method. The graphical forms of the acquired solutions have been displayed in the bell-shaped soliton, singular periodic, and anti-kink shape soliton solutions after the values for the free parameters were specified. The two non-algebraic solutions, named, exponential and trigonometric function solutions, have emerged by applying our proposed method. Based on the general findings of our investigation for different parametric values, the attained wave solutions revealed can keep a vital role for natural balances and can be engaged in modern physical applications. The parameters have a visible effect on the wave amplitude and the swiftness of the traveling wave. The executed outcomes are innovative and have monumental applications in the present research, especially in the fields of theoretical physics, astrophysics, plasma physics, particle physics, theory of relativity, advance quantum mechanics, string theory, and geotechnical engineering. © 2023 The Author(s)
