Run the ap whitelist sn ap-sn1 [ to ap-sn2 ] command to add the AP to the SN whitelist or run the ap-confirm command to enable the AP to pass authentication. The AP is not in the MAC whitelist. Run the ap whitelist mac ap-mac1 [ to ap-mac2 ] command to add the AP to the...
sn1==2*(1+2+3+……+n) sn2=n/2^(n-1)sn1是等差数列，用公式得sn1=n^2+n sn2=1*2^0+2*2^(-1)+……+n*2^(1-n)再用错位相减法，即：1/2sn2=1*2^(-1)+……+n*2^(-n)sn2=1.5+(n-1)*(1/2)^n 所以，sn=sn1+sn2=n^2+n-1.5-(n-1)/(2^n)OK啦！
Polar disconnection of the C(sp3)-N bond of N,N-dialkyl-substituted tertiary amines via ammonium species conventionally favored the loss of the smaller alkyl group by an SN2 displacement, while selective C(sp3)-N bond cleavage by cutting off the larger alkyl group is still underdeveloped. Herei...
because EMS can react by mixed SN1/SN2-type mechanisms, alkylation of the other sites of DNA is expectable. The ethylation of double-stranded DNA was studied in anin vitroexperiment that showed a 65% of ethylation in N7. For O6 and N3, the percentages of ethylation were 2 and 0.9, ...
Similarly, in three dimensions (see Figure 14.6c), in-plane shear may be applied using a relative displacement in the 1 and 2 directions through the control nodes n2 and n4, such that u1=0,δs/2,0 and u2=δs/2,0,0, as shown in Figure 14.6c. The control node, n1, remains ...

Their level of compliance towards family and neighbors was relatively neutral, so SN1-Family members (2.98) and SN3-Neighbors (2.93) received similar scores. Finally, they showed the lowest compliance toward their friends, which is reflected in the score for SN2-Friends (2.76). 4.1.3. ...

position of 3-HK, suggesting that this enzyme may use acid/base-mediated mechanism to catalyze the C-methylation reaction. Indeed, a general base/acid residue is required to initialize the SN2reaction in other MT family members21. The tyrosine residues in the proximity of active center may be...
