Pairs of middle-aged twins and their spouses provided data on 74 mainly psychological variables. Neither spousal similarity nor idiosyncratic criteria could account for specific mate selection in these 738 couples. Of the twins (and their spouses), 547 independently rated their initial attraction to their twin's mate (or to their spouse's twin): Findings suggest that characteristics both of the...

Understanding farmers’ intentions to use agricultural green production technologies (AGPTs) is essential for reducing pollution. Drawing on the Technology Acceptance Model (TAM), this study analyzes impacts of government regulation and social network AGPTs adoption behavior. Field research 738 responses in China revealed that were positively related behavior, effects mediated by perceived usefu...

We present a simple and e cient dictionary with worst case constant lookup time, equaling the theoretical performance of the classic dynamic perfect hashing scheme of Dietzfelbinger et al. (Dynamic perfect hashing: Upper and lower bounds. SIAM J. Comput., 23(4):738 761, 1994). The space usage is similar to that of binary search trees, i.e., three words per key on average. The practicality of th...

This work concern an extension of the asymptotic compensation problem in hyperbolic systems. We introduce and characterize the notion of asymptotic remediability, which consists to compensate asymp-totically a disturbance by a convenient choice of actuators (efficient actuators). We also study the relationship between these different notions and asymptotic controllability as well as strategic a...

The results of an X-ray observation of the nearby core-dominated, super-luminal quasar 4C +73.18 (1928+738) with ASCA are reported. Variations of the 1–10 keV flux on time-scales of the order of 10 hours were found while the 0.5– 1 keV flux remained almost unchanged. The measured flux at 1 keV had increased by ∼ 50% compared with previous observations 18 years ago. The quasar shows a curved spe...
