If a human of mass 70 kg took up the same amount of space as a sphere containing only his/her atomic nuclei, the sphere's radius would be only about 0.0004 cm. Protons and Neutrons in the Nucleus All nuclei are positively charged because of the presence of protons. Nearly all nuclei co...
The nucleus occupies only a tiny fraction of the volume of an atom (the radius of the nucleus being some 10,000 to 100,000 times smaller than the radius of the atom as a whole), but it contains almost all the mass. An idea of the extremedensityof the nucleus is revealed by a simpl...
The influence of the finiteness of the proton radius and mass on the energies of a hydrogen atom and hydrogen-like ions in a superstrong magnetic field is studied. The finiteness of the nucleus size pushes the ground energy level up leading to a nontrivial dependence of the value of critical...
Combining this information with histological descriptions of DR96,97 and the Allen Human Brain Atlas98, a spherical ROI (3 mm radius) was drawn around MNI coordinates x: 0, y: −30, z: −13. Any edge voxels close to the cerebral aqueduct of periaqueductal gray were trimmed, ...
Human striatal cells have a larger soma and dendritic radius compared with the monkey, but fewer spines (Graveland and DiFiglia, 1985). In addition, there is a second spiny neuron – type II spiny neuron that is relatively infrequent, (about 1%) and varies considerably in size (Graveland ...

The radius of this neighbourhood—which determines the loess ‘span’ parameter—can be changed by the user (default: 5). Median of loess-smoothed non-zero counts (\(M_{jk}^l\)) represents background CDS translation level, and the ratio \(\frac{{y_{ijk}^l}}{{M_{jk}^l}}\) ...
3.4.1 Nuclear reactions in free space A nucleus (called nuclide to specify its constituent characterized by the number of protons Z and the number of nucleons A, and the energy state) has a volume V proportional to A and therefore the radius of the nucleus RN is proportional to a cube ...
