3d znin2s4 nanosheets decorated zncds dodecahedral cages as multifunctional signal Amplification Matrix combined with electroactive photoactive materials for dual mode electrochemical photoelectrochemical detection of bovine hemoglobin
Biosensors and Bioelectronics, 2020Co-Authors: Hongyuan Shang, Liujun Jin, Cheng Wang, Chunyan Chen, Tongxin SongAbstract:Abstract The construction of dual mode sensor has gained tremendous attention due to its high accuracy and sensitivity compared with a single-response system. Herein, a novel dual mode sensing platform based on a 3-dimensional (3D) ZnCdS/ZnIn2S4 double-shelled dodecahedral cages (DSDCs) is fabricated as the electrochemical (EC) – photoelectrochemical (PEC) multifunctional signal Amplification Matrix for the highly selective detection of bovine hemoglobin (BHb). To achieve simple and fast detection of BHb, Au@Cu2O and SnO2/SnS2 are acted as EC – PEC signal indicators, respectively. More interestingly, the electroactive Au@Cu2O and photoactive SnO2/SnS2 are assembled on the 3D ZnCdS/ZnIn2S4 DSDCs, which could effectively increase the electron transfer process, consequently amplifying the readout of the dual mode responses. Besides, polydopamine (PDA) is used as a monomer for protein imprinting. Under the optimized conditions, the dual mode sensor exhibits a wide linear concentration range from 10−19 mg mL−1 to 10−1 mg mL−1 with a low detection limit 6.5 × 10−20 mg mL−1. Furthermore, the excellent selectivity, stability and acceptable reproducibility of the designed sensor will offer an alternation for the detection of other biomacromolecules in clinic diagnosis field.

Application of spinor calculus in stability analysis of finite-difference schemes
Computational Mathematics and Mathematical Physics, 2003Co-Authors: Evgenii V. Vorozhtsov, Boris Yu. ScobelevAbstract:Spinor analysis is applied to study the stability of finite-difference schemes in square norm. Necessary and sufficient stability conditions are obtained in terms of the coefficients in the decomposition of a Amplification Matrix over Pauli spin matrices. Formulas are derived for the coefficients in the spin expansion of an arbitrary power of the Amplification Matrix. Conditions are found for the asymptotic stability of a difference scheme. Decomposition of 4 x 4 transition matrices over the Dirac matrices is considered. Stability conditions are obtained for a class of difference schemes that includes the four-layer splitting schemes.

Parallel Implementation of Stability Analysis of Difference Schemes with MATHEMATICA
Journal of Mathematical Sciences, 2002Co-Authors: V. G. Ganzha, Evgenii V. VorozhtsovAbstract:We consider a parallel algorithm for investigating the stability of the schemes of the finite-difference and finite-volume methods that approximate the two-dimensional Euler equations of compressible fluid on a curvilinear grid. The algorithm is implemented with the aid of the computer algebra system Mathematica 3.0 . We apply a two-level parallelization process. At the first level, the symbolic computation of the Amplification Matrix is parallelized by a parallel computation of the Matrix rows on different processors. At the second level, the values of the coordinates of points of the stability-region boundary are computed numerically. For the communication between the workstations, we apply a special program, LaunchSlave , which uses the MathLink communication protocol. Examples of application of the proposed parallel symbolic/numerical algorithm are presented. Bibliography: 15 titles.

Sufficient stability criteria and uniform stability of difference schemes
Journal of Computational Physics, 2000Co-Authors: Boris Yu. Scobelev, Evgenii V. VorozhtsovAbstract:Abstract We prove two new criteria for the sufficiency of the von Neumann condition for stability of difference schemes. The first criterion is that the von Neumann criterion is sufficient for stability if a finite power of the Amplification Matrix is a uniformly diagonalizable Matrix. The second criterion relaxes the uniform diagonalizability requirement for the Amplification Matrix: The uniform diagonalizability is needed only in some subregion of the parameter values, and for the remaining parameter values, all the eigenvalues of the Amplification Matrix should be strictly less than unity in modulus. The numerical investigation of the behavior of the norms of powers of Amplification Matrix has pointed to the advisability of introducing a new definition, the uniform stability. We prove constructive criteria for uniform stability. We investigate the satisfaction of the obtained uniform stability criteria for a number of well-known difference schemes for the numerical solution of fluid dynamics problems.
