An aligned entry direction has a significant interaction with the first choice that an ant makes.
The entry direction is facilitated by a cohesin loader that appears to fold cohesin to expose the DNA sensor.
Table 1 and figure 1 c show the frequencies of first and second choices and entry direction.
A general log-linear analysis was performed on the three factors in the second experiment (entry direction, first choice and second choice), examining the significance of the two- and three-way interaction parameter estimates.
We next calculated the fraction of flies exiting the choice zone into the light-on side irrespective of its entry direction and found this 'choice probability' to be highly correlated with preference index.
In the second experiment, due to ants' well-established wall-following tendency [ 14], entry direction information is used to separate the two interacting factors of thigmotaxis (favouring a repeated choice of left left or right right) and a bias in favour of leftward choices.
Entry direction (via wall-following from the left or right, or unaligned) was not initially noted (n = 27 from three colonies) and was occasionally overlooked (n = 6), but nevertheless was recorded for the majority of trials (n = 80 from seven colonies).
Click the text, set Effect Action to all the photos as follow: Effect Action: "Entrance", Type: "Fly Entry", Direction: 90; Effect Action: "Emphasis", Type: "Color Wave"; Effect Action: "Exit", Type: "Jalousie Out", Direction: 90.
But Google recently released its cartographic impression of the Hermit Kingdom, and as usual, it comes with all the Googley goodies: just move your cursor across Kim Il-sung Square, and you'll be met with site labels, embedded photographs, Wikipedia entries, directions, ratings and reviews.
As such, ultrasound can be used for real-time guidance of needle entry and direction of insertion to attain the optimal position for vocal cord injection (Fig. 4).
