This paper uses two-timing to solve a class of reaction-diffusion equations of Oregonator and constructsformally stable target pattern solutions to leading term in small parameter, which can be used to account for someobserved experimental facts. In addition, it also gives the explicit expression of the period corresponding to the targetwaves.

Drug metabolism is an important issue in drug discovery. Understanding how a drug is metabolized in the body will provide helpful information for lead optimization. Cytochrome P450 2D6 （CYP2D6） is a key enzyme for drug metabolism and responsible for the metabolism of about one third marketed drugs. Aripiprazole is an atypical an- tipsychotic and metabolized by CYP2D6 to its hydroxylated form. In this study, a series of computational methods were performed to understand how CYP2D6 accomplishes the 4-hydroxylation of aripiprazole. Molecular docking and molecular dynamics simulations were first performed to prepare the initial conformations for QM/MM calcula- tions. The results revealed two possible conformations for the drug-CYP2D6 complex. The ONIOM method for QM/MM calculations was then carried out to show detailed reaction pathways for the CYP2D6-catalyzed aripipra- zole hydroxylation reaction, which demonstrated that the dominant reactive channel was electrophilic and involved an initial attack on the n-system of the dichlorophenyl group of aripiprazole to produce cation δ-complex. Further- more, the product complex for each conformation was thermodynamically stable, which is in good agreement with previous reports.

The nonthermal components in hard X-rays have been detected in two young supernova remnants （SNRs）： SN 1006 and Kepler＇s SNR. Various theoretical models showed that the amplification of the magnetic field was crucial to explain their multiband emission properties. We investigate the evolution of the magnetic field and model the multiband emissions from these two young SNRs with a time-dependent injection model. The results indicate that （1） the radio and X-ray emissions are re- produced by synchrotron radiation of the injected electrons, while the y-rays can be explained as inverse Compton scattering of the relativistic electrons and proton-proton interaction of the high-energy protons; and （2） the amplification of the magnetic field spontaneously happens with reasonable parameters.

The time-dependent non-thermal particle and photon spectra are reproduced for a Type Ia SNR Tycho with radio,x-ray,GeV and TeV emission within the framework of the diffusive shock acceleration of the non-thermal *** photons can come from the inverse Compton scattering of relativistic electrons and from theπ0−decay process in proton-proton *** results show that(1)the hadronic case can model the observed multiwavelength spectrum well and,peculiarly,theπ0-decay process appears to be necessary to explain the GeV emission;and(2)magnetic field amplification is vital in the SNR.
