In order to better understand the relationship between data analysis and cross-border selection, apply practical application skills of selection better. The author sorted out several commonly used tools, steps methods e-commerce. This paper mainly introduces role e-commerce product in selection. At same time, this also analyzed three techniques Cross-border is basis operation. process scientifi...

In the present population-based study including 70-year-old men and women, total dairy product intake was associated with a weak positive association with tibia trabecular and cortical cross-sectional areas. PURPOSE Milk consumption has recently been suggested to increase fracture risk. Therefore, we aimed to investigate associations between dairy product consumption and peripheral bone prope...

the genetics and mechanism of malathion resistance in the adults of an. stephensi (ban-s), was studied. nine successive generations of malathion selection in the adults resulted in an increase in ltso of about 3-fold. the crossing experiments indicated that the resistance is inherited as partially dominant character with no indication of sex linkage. the results of back-crosses suggested that p...

I this paper, we develop a theoretical model to analyze the pricing strategies of competing retailers with asymmetric cross-selling capabilities when product demand changes. Our results suggest that retailers with better opportunities for cross-selling have higher incentives to adopt loss-leader pricing on high-demand products than retailers with low cross-selling capabilities. As a result, pri...

In this paper we propose Runge-Kutta Fehlberg method for solving fully fuzzy differential equations (FFDEs) of the form y ′ (t) = a⊗ y(t), y(0) = y0, t ∈ [0,T ] under strongly generalized H-differentiability. The algorithm used here is based on cross product of two fuzzy numbers. Using cross product we investigate the problem of finding a numerical approximation of solutions. The convergence of...

We study the biparametric quantum deformation of GL(2) ⊗ GL(1) and exhibit its crossproduct structure. We derive explictly the associated dual algebra, i.e., the quantised universal enveloping algebra employing the R-matrix procedure. This facilitates construction of a bicovariant differential calculus which is also shown to have a cross-product structure. Finally, a Jordanian analogue of the d...

This paper introduces a new series of three-dimensional chaotic systems with cross-product nonlinearities. Based on some conditions, we analyze the globally exponentially or globally conditional exponentially attractive set and positive invariant set of these chaotic systems. Moreover, we give some known examples to show our results, and the exponential estimation is explicitly derived. Finally...

The anti-competitive effects of cross-holdings have been extensively analyzed in the literature. While the literature has generally focused on cases with homogenous products, this paper is the first attempt to analyze welfare as well as the anti-competitive effects of cross-holdings allowing for product differentiation. We show that the known results established with homogenous products continu...
