(R > Rcrit) from the centre. We adopted a critical radiusRcrit = 6,000 AU, which is twice the mean angular resolution, and performed two fits. First, we assumed a central source mass of 15 M⊙and fitted a Keplerian and a free-fall model to the two regimes. Second,...
(radiusr=9nm, refractive indexn=1.58) are fixed on the surface. The highest enhancement is obtained at low concentrations because, this case, the particles are trapped preferentially in the regions of highest electric field (hotspots). For high concentrations, it was observed that the hotspots ...
As a result, the irrigation water demand increase has enhanced the pressure exerted on the aquifer, leading to overexploitation reflected by a decrease in the water level between 0.25 and 1 m per year [73]. Figure 1. (a) Location of the study area in the Kairouan Plain at the center ...
The entire circuit is placed in a steadily increasing, uniform magnetic field directed into the plane of paper and normal to it. The rate of change of the magnetic field is 1 Ts−1. The resistance per unit length of the wire is 1Ω m−1. Find the magnitude...
Organisms have the capacity to make decisions based solely on internal drives. However, it is unclear how neural circuits form decisions in the absence of sensory stimuli. Here we provide a comprehensive map of the activity patterns underlying the genera
