摘要： The relation of matter wave, which is well-known as a hypothesis proposed by de Broglie in 1923, gave basis for establishing the quantum mechanics. After that, experimental results revealed that a micro particle has a wave nature. However, the theoretical validity of the relation itself has never been revealed since his proposal. Theoretical basis that a micro particle has a wave nature has been thus disregarded in the unsolved state. The diffusion equation having been accepted as Fick’s second law was derived from the theory of Markov process in mathematics. It was then revealed that the diffusivity D depends on an angular momentum of a micro particle in a local space. The fact being unable to discriminate between micro particles in a local space resulted in having to accept the existence of minimum time t0 (>0) in the quantum mechanics. Based on t0 and D obtained here, the theoretical validity of relation of matter wave was confirmed. Denying the density theorem in mathematics for time in physics indicates that the probabilistic interpretation is essentially indispensable for understanding the quantum mechanics. The logical necessity of quantum theory itself is thus understandable through introducing t0 into the Newton mechanics. It is remarkable that the value of t0 between 1.14×10-17 s ≤ t0 ≤1.76×10-14 s obtained here is extremely larger than that of the well-known Planck time tp=5.396×10-44 s.

摘要： A projected plasma efavirenz concentration profile of a patient who had been on an orally administered 600 mg daily dose of efavirenz is used as the variable that is a directing lead. A four compartmental model of ordinary differential equations is suggested and solved numerically. This model projects descriptors associated with concentration dispersion subject to trace and bounce constraints. The stimulant-action unit is responsible for directing the bounce. A description of the cross-sectional structure of the quantum is suggested. A dynamical system with an attractive (zero eigenvalue) subspace as a structural state is derived. The structure is an intensity-effect measure. The bounce’s Jacobian Matrix has negative eigenvalues which correspond to A-action-stimulation, S-action-intensity and P-effect-stimulation and these leads govern the structure (C). The three paths, action-stimulation, action-intensity and effect-stimulation lead to the structure of an effect-intensity.

摘要： Statistical and Quantum numerical method was implemented in this study to solve various cases in partial differential equations (PDEs) in engineering applications. One-dimensional with two lattices arrangements as well as two-dimensional with nine lattices arrangements is employed. The stability and the accuracy have been investigated either using statistical technique or using Euler’s method. The numerical limitations of using LBM method have been obtained and compared with those obtained by Euler’s method finite difference method. The main goal of this study is to investigate the ability of a statistical method in solving various ODEs or PDEs in energy and momentum equations and comparing them with those obtained by a classical numerical technique. The results show the ability of the statistical method for solving ODEs and PDE’s with more stable and accurate results. Therefore, the motivation of utilizing the statistical technique is the stability and it is easy for a complex fluid flow application.

摘要： Malaria is a severe illness triggered by parasites that spreads via mosquito bites.In underdeveloped nations,malaria is one of the top causes of mortality,and it is mainly diagnosed through microscopy.Computer-assisted malaria diagnosis is difficult owing to the fine-grained differences throughout the presentation of some uninfected and infected groups.Therefore,in this study,we present a new idea based on the ensemble quantum-classical framework for malaria classification.The methods comprise three core steps:localization,segmentation,and classification.In the first core step,an improved FRCNN model is proposed for the localization of the infected malaria cells.Then,the RGB localized images were converted into YCbCr channels to normalize the image intensity values.Subsequently,the actual lesion region was segmented using a histogram-based color thresholding approach.The segmented images were employed for classification in two different ways.In the first method,a CNN model is developed by the selection of optimum layers after extensive experimentation,and the final computed feature vector is passed to the softmax layer for classification of the infection/non-infection of themicroscopicmalaria images.Second,a quantum-convolutionalmodel is employed for informative feature extraction from microscopicmalaria images,and the extracted feature vectors are supplied to the softmax layer for classification.Finally,classification results were analyzed from two different models and concluded that the quantum-convolutional model achieved maximum accuracy as compared to CNN.The proposed models attain a precision rate greater than 90%,thereby proving that these models performed better than the existing models.

摘要： To alleviate the secondary contamination of our environment when using quantum dots(QDs) to detect the organophosphorothioate pesticides(OPPs),we herein report a strategy to assemble magnetic Fe_(3)O_(4) nanoparticles and luminescent Cd Te quantum dots(QDs) into a composite nanosystem,which possesses both the magnetic property of Fe_(3)O_(4) nanoparticles and the luminescent character of Cd Te QDs,for the detection of chlorpyrifos,one of the typical OPPs.This strategy involves the isolated synthesis of magnetic Fe_(3)O_(4) nanoparticles with positive charges and luminescent Cd Te QDs with negative charges,and their subsequent assembly by electrostatic interaction.The as-prepared Fe_(3)O_(4)-Cd Te nanocomposites have a detection limit as low as 10 ppb for chlorpyrifos,and are also selective for the OPPs with a phosphorothioate moiety(P=S bond).In specific,the Fe_(3)O_(4)-Cd Te nanocomposites can be conveniently harvested by a normal magnet,and the recycling rate for both Cd and Fe determined by inductively coupled plasma atomic emission spectroscopy(ICP-AES) is higher than 96%,showing great potential in alleviating the Cd pollution on the environment.

摘要： A novel model of spacetime and fields atomization based on Atomic Series over finite Atomic AString Functions is offered. Formulated Atomization Theorems allow representing polynomials, analytic functions, and solutions of field equations including General Relativity via superposition of solitonic atoms which can be associated with flexible spacetime quantum, metriants, or elementary distortions. Spacetime is conceptualized as a lattice of flexible Atomic Solitons adjusting locations to reproduce different metrics and other physical fields. It may offer the variants of unified field theory based on Atomic Solitons where, like in string theory, fields become interconnected having a common mathematical ancestor.

摘要： N-doped reduced graphene oxide quantum dots(N-rGQDs) have attracted more and more attention in efficient catalytic degradation of aqueous organic pollutants.However,the synthesis of N-rGQDs is generally a complex and high energy required process for the reduction and N-doping steps.In this study,a facile and green fabrication approach of N-rGQDs is established,based on a metal-free Fenton reaction without additional energy-input.The N structures of N-rGQDs play a significant role in the promotion of their catalytic performance.The N-rGQDs with relatively high percentage of aromatic nitrogen(NAr-rGQDs) perform excellent catalytic activities,with which the degradation efficiency of pollutant is enhanced by 25 times.Density functional theory(DFT) calculation also indicates aromatic nitrogen structures with electron-rich sites are prone to transfer electron,presenting a key role in the catalytic reaction.This metal-free Fenton process provides a green and costeffective strategy for one-step fabrication of N-rGQDs with controllable features and potential environmental catalytic applications.

摘要： MOST people make several phone calls a day and very few keep records of the date and time.But the call made between Austrian physicist Anton Zeilinger,who won the Nobel Prize in phys­ics this year,and Bai Chunli,then president of the Chinese Academy of Sciences(CAS),on September 29,2017,has gone down in the annals of quantum science as the first intercon­tinental quantum-secure communication video call.Bai was in Beijing and Zeilinger in Vienna,and the communication was possible through a sophisticated Chinese research satel­lite named Micius,the world’s first quantum communication satellite developed and launched into orbit by the CAS just the year before.
