Matrix weights and a maximal function with exponent 3/2 by Treil Sergei, Volberg Alexander

“…We build an example of a simple sparse operator for which its norm with scalar A 2 weight has linear estimate in [w]A2 ${\left[w\right]}_{{A}_{2}}$ , but whose norm in matrix setting grows at least as [W]A23/2 ${\left[W\right]}_{{\mathbf{A}}_{2}}^{3/2}$ for specially constructed weights from A 2. We also demonstrate a matrix weighted maximal function with the same estimate from below.…”

Design keyed Hash function based on couple chaotic system by WEI Peng-cheng1, ZHANG Wei 1, 2, LIAO Xiao-feng 1

“…Analyzed the chaotic and cryptographic properties of a piecewise nonlinear map, a couple chaotic digital sys-tem was proposed based on perturbing which used the piecewise nonlinear, then a new approach to construct keyed Hash function was presented. The approach used the initial value of the couple chaotic system as the secret key and the coarse-graining trajectory as Hash values. …”

Validation of functional activity index in patients with rheumatoid arthritis (RAS) by V. N. Amirdjanova, O. M. Folomeeva, S. F. Erdes

“…Validity assessment was performed on 454 pts with definite RA,mainly female (85,2%) with mean age 51,3±11,3 years, mean disease duration was 9,1±8,5 years, 59,7% of pts were seropositive on rheumatoid factor, most pts had moderate or high inflammatory activity of the disease (95,6%), II or III radiological stage ( 44,7% and 27,8% respectively, II (53,5%) or III (31,8%) functional class. Constructive validity of the index was assessed by calculation of coefficients of correlation with “external criteria”. …”

A pair of biorthogonal polynomials for the Szegö-Hermite weight function by N. K. Thakare, M. C. Madhekar

“…A pair of polynomial sequences {Snμ(x;k)} and {Tmμ(x;k)} where Snμ(x;k) is of degree n in xk and Tmμ(x;k) is of degree m in x, is constructed. It is shown that this pair is biorthogonal with respect to the Szegö-Hermite weight function |x|2μexp(−x2), (μ>−1/2) over the interval (−∞,∞) in the sense that∫−∞∞|x|2μexp(−x2)Snμ(x;k)Tmμ(x;k)dx=0,   ifm≠n                    ≠0,   ifm=nwhere m,n=0,1,2,… and k is an odd positive integer.…”

Searching for Slip Surface of Disturbed Slope Based on Logistic Function by Yalin Zhu, Xuefeng Peng, Kun Tan, Ming Shi, Yin Hong, Yixian Wang

“…The related parameters (M, A, and K) are derived by the threshold, symmetry, and precision control of its function. Logistic function constructs the slip surface and compares it with the broken-line slip surface; the numerical results show that the slip points on the two slip surfaces are consistent, indicating that the logistic function fits the curve correctly; the logistic function smooths the original polyline curve, which facilitates solving the direction vector of the curve.…”
