Acoustic waves such as compressive, shear and Rayleigh are generated by 1 MHz central frequency contact transducers exited by a voltage pulse generator.
In Drosophila salivary gland nuclei, pericentromeric heterochromatin attaches permanently to the NE, while intercalary heterochromatin forms high-frequency contacts to NE [ 34].
Figure 4, 5, 6 and 7 show the final classification trees for touching, contact location, contact frequency and contact duration, respectively.
These include the distribution of particle residence time, mean residence time, contact frequency, and contact distance at the walls.
Here we hypothesize that the auditory demands of percussive foraging resulted in a receiver bias that precluded the evolution of lower-frequency contact calls.
We also wanted to avoid distracting from the basic idea of describing frequency of contacts and inter-contact intervals.
'Tree usage' refers to the use of the variables in the tree construction for tree 1: physical contact; 2: contact location; 3: contact frequency and 4: contact duration.
Self-reporting of skin contact and frequency of contact were used as an index of exposure.
The table shows similarity between rural and urban frequency of contacts, reflecting higher reported frequency of contact by women regardless of location.
Friendship between nodes is characterized on the basis of the frequency of contacts and number of long-lasting, regular contacts.
