In intact Hydra polyps, the expression of neurogenesis genes is spatially regulated, being restricted to the i-cells in the central portion of the body, and that of neurotransmitter genes is highest at the head and foot regions, where the nervous system is densest.
Meanwhile, its associated warm front progresses more slowly, as the cooler air ahead of the system is denser, and therefore more difficult to dislodge.
The large-scale image of Figure 1A shows that the SiNWs from HF/AgNO3 system are dense and in an orderly and vertical orientation.
As a by product, we show that the set of proper time-invariant linear systems is dense in the set of regular linear descriptor systems.
Its buildings have automatic climate control and computerised access; its roads and water, waste and electricity systems are dense with electronic sensors to enable the city's brain to track and respond to the movement of residents.
The characteristics that distinguish pictorial systems from other denotational systems (e.g., from natural languages) make them the very opposite of a notation: pictorial systems are dense throughout and in that respect are similar to other analog systems, such as those of diagrams and maps (1976, 194 198; Goodman, Elgin 1988, Chap. 7).
Our proof is based on constructing function system which is dense and periodic under the acting of the solution semigroup, which is a totally complex-analytic approach.
The major cementing material in this systems tract is dense micritic calcite.
Co-operative system measure: traffic light status emitted to the car The focus of the co-operative system is on dense traffic (e.g. large lorry in front obstructing view on traffic light) and on adverse weather conditions.
The β-END innervation of the ependymal and subependymal layers surrounding the ventricular system is extremely dense at some locations but varies considerably [ 67, 68, 70, 73- 76, 93, 95, 104].
