We investigate the number of singular points of the curve FS(t,x,y)=0, and show that the number of singular points of FS(t,x,y)=0 associated with a cyclic weighted shift matrix whose weights are neither 1-periodic nor 2-periodic is less than or equal to n(n3)/2. Furthermore, ...
You are given a matrix consisting ofnnrows andmmcolumns. The matrix contains lowercase letters of the Latin alphabet. You can perform the following operation any number of times you want to: choose two integersii(1≤i≤m1≤i≤m) andkk(0<k<n0<k<n), and shift every columnjjsuch thati...
A generator matrix of this code is (3.8) G=(110011) . A linear code is called cyclic if any cyclic shift of a codeword is also a codeword. Here, a cyclic shift of a vector (3.9)a = (a0 a1 a2⋯ an−1) is defined as (3.10)a′ =(an...
The second extended the number of L2, that is connected to the first extension in the establishment of a selection of cyclic shift offset, each connection corresponds to a size of L2 × L2 unit cyclic matrix. 此方法借鉴了PEG算法的局部优化思想构造准循环LDPC码的基矩阵,在逐列为变量节点与校验...

A growing body of evidence indicates that the shift from embryonic to maternal control of the decidual process represents a pivotal evolutionary adaptation to the challenge posed by invasive and chromosomally diverse human embryos. This concept is predicated on the ability of decidualizing stromal cells...
The second component vector denotes the time shift from one iteration to the other. Without blocking of the operations belonging to several sample intervals, this component is equal to the iteration period. Example 7.6 Consider the second-order section in direct form II shown in Figure 7.10. ...
(2b, 4.6 kDa) telechelic precursor to produce selectively bridged bicyclic (3a, 6.7 kDa) and tricyclic (3b, 11.1 kDa) paddle-shaped polymers, respectively (Scheme 3).38 The formation of these products was evaluated with SEC, which showed a noticeable peak shift to a higher molecular weight....
