 reference
 The authors extend and improve some known results, and show that there are some errors in reference on inequalities for sequence rearrangement by examples. The blank reference experiment shows that hydrothermal crystallization treatment favors the formation of hexagonal tungsten trioxide, and the tungsten trioxide powder sample prepared by this method has a high degree of crystallinity. This paper provides a reference on calculating the binding-site number in proteins for ligands and studying their interactions by fluorescence spectroscopic methods. The proposed algorithm can easily identify which sector the reference space vector falls in and conduct simple operations to find the duty cycle of each vector. The similar parts in MANET routing protocol are used in the satellite network for reference. 更多
 datum
 We use this approach together with the new datum in order to investigate its implications for the baryon spectrum. The Vallesian lower boundary and "Hipparion-datum" are estimated as ranging in age from 11.2 to 10.7 Ma in Central to Western Europe and Western Asia. The geometrical accuracy of a machined feature on a workpiece during machining processes is mainly affected by the kinematic chain errors of multi-axis CNC machines and robots, locating precision of fixtures, and datum errors on the workpiece. A mapping model between the displacements of workpieces and the datum errors, and adjustments of fixtures is established. The life-test datum with an accumulative count about 1011 is obtained; the structure and composition of active surface of fatigued CEM are analyzed by using AES. 更多
 benchmark
 The numerical simulations on several benchmark problems show that the scheme is very efficient. The test by some benchmark problems shows that the proposed algorithm achieves relatively higher performance. Experimental results for MCNC benchmark circuits are given. All this is supported by the experimental study on benchmark circuits. The experimental results with the adaptive control on the "Helicopter" benchmark were described. 更多
 base
 Geometric construction of the global base of the quantum modified algebra of However the compatibility of the canonical base of the modified algebra and of the geometric base given by intersection cohomology sheaves on the affine flag variety was never proved. We prove that these determinantal semi-invariants span the space of all semi-invariants for any quiver and any infinite base field. For $\gamma\in\mathbb{R}$ let $C(\gamma)$ be the set of all $f\in{\mathcal S}^\prime$ for which$\sum_{n=0}^{\infty}\,|(f,h_n)|\,(n+1)^{\gamma}>amp;lt;\infty$, where $(h_n)_{n=0,1,\dots}$ is the orthonormal base of Hermite functions. A gene regulatory mechanism has been proposed in which steroid hormones and certain other drugs bind to nuclear receptor proteins followed by transfer to DNA where they are inserted between base pairs. 更多
