A novel atom trap is described using alternating current to generate the magnetic B field, together with high speed polarization switching of the damping laser field. This combination produces a trap as effective as a standard magneto-optical trap (MOT), with the advantage that the average B field is zero. No net current is hence induced in surrounding conductive elements, and the B field produ...

dered if guidance cue-induced changes in NFPC protein synthesis may play a role here. Interestingly, stimulating cultured growth cones with Sema3A, a repellent molecule expressed in telencephalic regions adjacent to the MOT, elevates NFPC protein twofold within 10 min. Therefore, we now postulate a growth cone turning mechanism involving Sema3A-induced increases in TAF1mediated NFPC activity at...

To improve traffic safety and mobility in work zone areas, the Dynamic Lane Merge (DLM) systems, intelligent work zone traffic control systems, have been explored by several states of the U.S.A. The DLM can take two forms; dynamic early merge and dynamic late merge. The DLM systems were designed to advise drivers on definite merging locations. Up to date, there are no studies that contrast both...

Recent research has shown that holding telephone conversations disrupts one's driving ability. We asked whether this effect could be attributed to a visual attention impairment. In Experiment 1, participants conversed on a telephone or listened to a narrative while engaged in multiple object tracking (MOT), a task requiring sustained visual attention. We found that MOT was disrupted in the tele...

During 1996 and 1997 two empirical investigations into the importance of management of technology (MOT) issues (unresolved MOT problems) were completed. In these studies more than 150 academic and industry participants @om 17 countries evaluated the importance of each MOT issue relative to the others of its study. Each stu~ used a DELPHIIssues Questionnaire methodology which involved multiple q...
