| 1 | Entanglement and Sudden Death for a Two-Mode Radiation Field Two Atoms显示文摘The effect of the field–field interaction on a cavity containing two qubit(TQ)interacting with a two mode of electromagnetic field as parametric amplifier type is investigated.After performing an appropriate transformation,the constants of motion are calculated.Using the Schrödinger differential equation a system of differential equations was obtained,and the general solution was obtained in the case of exact resonance.Some statistical quantities were calculated and discussed in detail to describe the features of this system.The collapses and revivals phenomena have been discussed in details.The Shannon information entropy has been applied for measuring the degree of entanglement(DE)between the qubits and the electromagnetic field.The normal squeezing for some values of the parameter of the field–field interaction is studied.The results showed that the collapses disappeared after the field–field terms were added and the maximum values of normal squeezing decrease when increasing of the field–field interaction parameter.While the revivals and amplitudes of the oscillations increase when the parameter of the field–field interaction increases.Degree of entanglement is partially more entangled with increasing of the field-field interaction parameter.The relationship between revivals,collapses and the degree of entanglement(Shannon information entropy)was monitored and discussed in the presence and absence of the field–field interaction. | Eman M.A.Hilal E.M.Khalil S.A.bdel-Khalek | 2021 | Computers, Materials & Continua2021，，2： | 0 |
| 2 | Optimized Deep Learning Model for Colorectal Cancer Detection and Classification Model显示文摘The recent developments in biological and information technologies have resulted in the generation of massive quantities of data it speeds up the process of knowledge discovery from biological systems.Due to the advancements of medical imaging in healthcare decision making,significant attention has been paid by the computer vision and deep learning(DL)models.At the same time,the detection and classification of colorectal cancer(CC)become essential to reduce the severity of the disease at an earlier stage.The existing methods are commonly based on the combination of textual features to examine the classifier results or machine learning(ML)to recognize the existence of diseases.In this aspect,this study focuses on the design of intelligent DL based CC detection and classification(IDL-CCDC)model for bioinformatics applications.The proposed IDL-CCDC technique aims to detect and classify different classes of CC.In addition,the IDLCCDC technique involves fuzzy filtering technique for noise removal process.Moreover,water wave optimization(WWO)based EfficientNet model is employed for feature extraction process.Furthermore,chaotic glowworm swarm optimization(CGSO)based variational auto encoder(VAE)is applied for the classification of CC into benign or malignant.The design of WWO and CGSO algorithms helps to increase the overall classification accuracy.The performance validation of the IDL-CCDC technique takes place using benchmark Warwick-QU dataset and the results portrayed the supremacy of the IDL-CCDC technique over the recent approaches with the maximum accuracy of 0.969. | Mahmoud Ragab Khalid Eljaaly Maha Farouk SSabir Ehab Bahaudien Ashary S.M.Abo-Dahab E.M.Khalil | 2022 | Computers, Materials & Continua2022，，6： | 0 |
| 3 | Model of Fractional Heat Conduction in a Thermoelastic Thin Slim Strip under Thermal Shock and Temperature-Dependent Thermal Conductivity显示文摘The present paper paper,we estimate the theory of thermoelasticity a thin slim strip under the variable thermal conductivity in the fractional-order form is solved.Thermal stress theory considering the equation of heat conduction based on the time-fractional derivative of Caputo of orderis applied to obtain a solution.We assumed that the strip surface is to be free from traction and impacted by a thermal shock.The transform of Laplace(LT)and numerical inversion techniques of Laplace were considered for solving the governing basic equations.The inverse of the LT was applied in a numerical manner considering the Fourier expansion technique.The numerical results for the physical variables were calculated numerically and displayed via graphs.The parameter of fractional order effect and variation of thermal conductivity on the displacement,stress,and temperature were investigated and compared with the results of previous studies.The results indicated the strong effect of the external parameters,especially the timefractional derivative parameter on a thermoelastic thin slim strip phenomenon. | F.S.Bayones S.M.Abo-Dahab Ahmed E.Abouelregal A.Al-Mullise S.Abdel-Khalek E.M.Khalil | 2021 | Computers, Materials & Continua2021，，6： | 0 |
| 4 | Entanglement and Entropy Squeezing for Moving Two Two-Level Atoms Interaction with a Radiation Field显示文摘In this paper,we analyzed squeezing in the information entropy,quantum state fidelity,and qubit-qubit entanglement in a time-dependent system.The proposed model consists of two qubits that interact with a two-mode electromagnetic field under the dissipation effect.An analytical solution is calculated by considering the constants for the equations of motion.The effect of the general form of the time-dependent for qubit-field coupling and the dissipation term on the temporal behavior of the qubit-qubit entanglement,quantum state fidelity,entropy,and variance squeezing are examined.It is shown that the intervals of entanglement caused more squeezing for the case of considering the time-dependent parameters.Additionally,the entanglement between the qubits became more substantial for the case of time dependence.Fidelity and negativity rapidly reached the minimum values by increasing the effect of the dissipation parameter.Moreover,the amount of variance squeezing and the amplitude of the oscillations decreased considerably when the time dependence increased,but the fluctuations increased substantially.We show the relation between entropy and variance squeezing in the presence and absence of the dissipation parameter during the interaction period.This result enables new parameters to control the degree of entanglement and squeezing,especially in quantum communication. | S.Abdel-Khalek E.M.Khalil Beida Alsubei A.Al-Barakaty S.M.Abo Dahab | 2021 | Computers, Materials & Continua2021，，3： | 0 |
