也就是说,retain是指针拷贝,copy是内容拷贝。strong，weak用来修饰属性。strong用来修饰强引用的属性；@property(strong)SomeClass*aObject;对应原来的@property(retain)SomeClass*aObject;和@property(copy)SomeClass*aObject;weak用来修饰弱引用的属性；@property(weak)SomeClass*aObject;对应原来的@property...
The efficiency is uniform over weak or strong serial correlation and non-stationary volatility of unknown form. The feasible estimator relies on non-parametric estimation of the volatility function, and the asymptotic theory is provided. We use the data-dependent smoothing bandwidth that can ...
6.1 Identifying Multiple Samples In general, the critical parameters for evaluating side-channel attacks are the data complexity (in the first place) and the time complexity (when the order of Extractors against Side-Channel Attacks: Weak or Strong? 267 Fig. 8. Single sample attacks with paral-...

This is relevant to the current discussion on the pairing mechanism of FeSC in both KFS and FS/STO as the lack of hole pockets do not seem to prevent them from superconducting at temperatures comparable to or even higher than FePns, which is unexpected from a weak- coupling FS nesting ...
In this model, all from the regression coefficient is all not the zero, also its t statistics indicated has the strong significance, explains the Shenzhen A ingredient index sequence date return rate existence lag the relevance.Therefore Shenzhen Stock market does not assume the weak -like validity...
However, a weak, but significant, negative correlation (Rho -0.22, P < 0.05) was observed between vitamin E and oxLDL levels. In addition, malnourished patients had significantly elevated CRP and fibrinogen levels, whereas TNF-α levels did not differ. Table 3. Vascular, lipid and inflammatory...
Therefore, the zone of destruction account cannot explain forgetting in the medium- or high-strength conditions. Discussion Here we have presented a novel analysis employing initial memory strength to watch induced forgetting unfold across weak and strong memories. We have described the results of ...
strong TI, weak TI, and Dirac semi-metal, have been observed in different experiments until now. Essentially whether ZrTe5 or HfTe5 has a band gap or not is still a question. Here, we present detailed first-principles calculations on the electronic and topological prop- erties of ZrTe5 ...
