The dependence on the mass number of the rms radius and of the harmonic oscillator spacing ℏω Λ for a hyperon in a nucleus which has been a matter of discussion in the past, is investigated and improved expressions are proposed. Furthermore it is concluded that the law ℏω Λ≅...
What is the origin of the oxygen we breathe, the hydrogen and oxygen (in form of water H2O) in rivers and oceans, the carbon in all organic compounds, the
Furthermore, motivated by hydro-dynamical considerations, the dependence on the transverse mass mT=m2c4+KT2c2 is often studied, where m is the particle mass. The mT -dependence of the source parameters, such as its width, the so-called HBT scale, or radius R, was crucial in understanding ...
Using equations based on the law of mass action, the model then computes how the overall probability of binding between two cell types emerges from the distinct spectrum of cell-surface receptors that connect them (Extended Data Fig. 7). Although greatly simplistic, our model could still infer ...
Antigen binding by B cell receptors (BCR) on cognate B cells elicits a response that eventually leads to production of antibodies. However, it is unclear what the distribution of BCRs is on the naïve B cell and how antigen binding triggers the first step in BCR signaling. Using DNA-PAIN...
A sphere of metal has a radius of {eq}5.7 \ cm {/eq} and a density of {eq}8.33 \ g / cm^3 {/eq}. What is the mass of the sphere? Volume and Mass of Sphere: Firstly, the value of the volume of the given metal sphere is computed ...
Estimate the number of atoms in the earth. The earth has a radius of {eq}\rm 6000 \ km {/eq} and a mass of {eq}\rm 6 \times 10^{24} \ kg. {/eq} Atom: An atom is a tiny matter having a mass due to the cluster of protons and ...
Virtually all the mass of an atom resides in its nucleus, according toChemistry LibreTexts. The protons and neutrons that make up the nucleus are approximately the same mass (the proton is slightly less) and have the same angular momentum, or spin. ...
Baculovirus Autographa californica multiple nucleopolyhedrovirus (AcMNPV) has been widely used as a bioinsecticide and a protein expression vector. Despite their importance, very little is known about the structure of most baculovirus proteins. Here, we
It can be assumed that it consists of a double-magic, relatively stable 208Pb core nucleus surrounded by an α-like cluster. This α-like quartet experiences a potential pocket for the center-of-mass (c.m.) motion outside a critical radius rcr where it can exist as a quasi-bound state...
