Cervical cancer is one of the deadliest diseases in women. One of the cervical cancer screening methods is pap smear method. However, using a pap smear method to detect cervical cancer takes a long time for a pathologist to diagnose. Hence, a rapid development of medical computerization for early detection to get the results quickly is needed. This paper proposes synthetic data augmentation by using Deep Convolutional Generative Adversarial Network (DCGAN) to increase number of pap smear samples in dataset. Gray Level Co-occurrence Matrix (GLCM) is employed to extract features from dataset. Classification of 3 classes which are Adenocarcinoma, High-Grade Squamous Intraepithelial Lesion (HSIL), and Squamous Cell Carcinoma (SCC) is conducted using Extreme Learning Machine (ELM). The result shows that the addition of synthetic data improves the performance of ELM with the accuracy of 90%. This accuracy is better than the accuracy of ELM using only the original dataset which is 85%.

We synthesized single crystals for Mn2-xZnxSb(0 ≤ x ≤ 1) and studied their magnetic and electronic transport properties. This material system displays rich magnetic phase tunable with temperature and Zn composition. In addition, two groups of distinct magnetic and electronic properties, separated by a critical Zn composition of x = 0.6, are discovered. The Zn-less samples are metallic and characterized by a resistivity jump at the magnetic ordering temperature, while the Zn-rich samples lose metallicity and show a metal-to-insulator transition-like feature tunable by magnetic field. Our findings establish Mn2-xZnxSb as a promising material platform that offers opportunities to study how the coupling of spin, charge, and lattice degrees of freedom governs interesting transport properties in 2D magnets, which is currently a topic of broad interest. © 2023, The Authors.

In the literature, one can find numerous modifications of Fourier's law from which the first one is called Maxwell-Cattaneo-Vernotte heat equation. Although this model has been known for decades and successfully used to model low-temperature damped heat wave propagation, its nonlinear properties are rarely investigated. In this paper, we aim to present the functional relationship between the transport coefficients and the consequences of their temperature dependence. Furthermore, we introduce a particular implicit numerical scheme in order to solve such nonlinear heat equations reliably. We investigate the scheme's stability, dissipation, and dispersion attributes as well. We demonstrate the effect of temperature-dependent thermal conductivity on two different initial-boundary value problem, including time-dependent boundaries and heterogeneous initial conditions. © 2023, CC BY.

Currently, only one shallow acceptor (Mg) has been discovered in GaN. Here, using photoluminescence (PL) measurements combined with hybrid density functional theory, we demonstrate that a shallow effective-mass state also exists for the BeGa acceptor. A PL band with a maximum at 3.38 eV reveals a shallow BeGa acceptor level at 113±5 meV above the valence band, which is the lowest value among any dopants in GaN reported to date. Calculations suggest that the BeGa is a dual-nature acceptor with the “bright” shallow state responsible for the 3.38 eV PL band, and the “dark,” strongly localized small polaronic state with a significantly lower hole capture efficiency.

We suggest a simple, practical device with a wireless sensor network system that can be used to record and display data from a spring oscillation system in real-time on a website. The HC-SR04 ultrasonic sensor was utilized to detect changes in load position in the damped spring oscillation system, and the Node-MCU ESP266 was used to transmit data from sensor readings to the server over the internet network. The damping factor, damping coefficient, and spring damping frequency could be utilized to calculate the exponential function graph fitting outcome. © 2021 IOP Publishing Ltd.

We study the hierarchy between MT, vL, and vR, the relevant energy scales of the Minimal Universal Seesaw Model (MUSM), where the two lightest quark families remain massless at tree level. We also predict the heavy top quark mass, mt′ . We do some numerical analysis using recent experimental data. Our numerical analysis demonstrates that MT is sensitive to the values of the Yukawa couplings. The heavy top quark mass (mt′) is predicted to be within the range from 1.4 TeV to 7.2 TeV. © 2024, CC BY.

A quantum internet is an emerging quantum information technology, possibly becoming a pinnacle of wide-area distributed system allowed under the laws of physics. The current expansion of quantum technologies would lead to innumerable types of quantum systems, composed of various kinds of quantum devices connected by a dedicated quantum network. However, the (inter)connectivity offered by a quantum internet should ideally be agnostic of the technologies used by each component system. Furthermore, concurrent progresses of the quantum technologies complicate the task of defining what a quantum internet is. In this paper, we adopt a backcasting approach to elucidate what a quantum internet should be. We begin by discussing what we believe to be the requirements of an ultimate distributed quantum system, from which we explain what role a quantum internet would play in achieving this ultimate system. We then lead to more practical requirements on a quantum internet, considering the known and expected constraints in designing a quantum internet. We also organize and categorize the relationship among known quantum network technologies and services relevant to a quantum internet. We hope this document to lay a common ground for all the key stakeholders of a quantum internet, including researchers, industrial enterprises, and policy makers and regulators.

We propose an SU(5)×U(1)X×U(1)PQ model without SUSY because the SUSY particles have not been observed yet. The U(1)X gauge symmetry is the generalization of the U(1)B−L gauge symmetry and U(1)PQ symmetry is the global Peccei-Quinn symmetry. We introduce three mirror families in order to unify the SM gauge couplings and avoid the restriction of proton lifetime. In order to obtain the difference of the masses for the down-type quarks and charged leptons, we also introduce the 45 representation Higgs in addition to the 5 representation one. In this paper, we discuss the mass relations between the SM and mirror particles and identify the mass scales of the mirror particles. Since the new particles exist in the intermediate energy scale and contribute to the renormalization group equation, the SM gauge couplings unify successfully at high energy. Our model can be tested by the future proton decay search, e.g., the Hyper-Kamiokande experiment expected as τp(p → π0e+) 35 years. Also, by using the mass relations between the active and mirror neutrinos, we estimate the lower bound of the heavy neutrino masses. © 2022, CC BY.
