18.According to the key tenets of modern physics, the cosmos is “isotropic” at multi-billion-light-year scales—meaning it should have the same look and behavior in every direction. 19.Would you say that the distribution of elephants on Earth is homogeneous and isotropic?
In summary, the constraint Rijkl=K(gikgjl−gilgjk) implies that the resulting space is maximally symmetric, meaning that it is specified by just one number - the curvature K, which is independent of the coordinates. This constant curvature space must be both homogeneous and isotropic. How...
The H+2 . meaning of processes 1, 2 and 3 is explained in the text. up to a point that only even harmonics are observed for high enough orders. The spectral region where even har- monics dominate shifts to higher orders with increasing pulse duration. For the 20-cycle pulse even ...
Its radiation resistance will continue to decrease, and its reactance will become increasingly capacitive (meaning negative). Reciprocally, an antenna longer than lambda/4 will have a higher radiation resistance and an inductive reactance (like a long wire), so in both cases it is no longer ...
In addition, we investigate more cases where there are material holes in the design domain, meaning that the density of the material is zero. In this study, the modified SIMP method and filter sensitivity are used for topology optimization. The results of the study...
This undesirable feature also underlines the importance of the third identified trait, namely the advantage in having a model with molecular/structural basis which in turn ensures a degree of physical objectivity and meaning for the embodied model parameters (e.g., Anssari-Benam and Bucchi, 2021...
The data used are the same as those in Fig. 3. When plotted this way, it shows that the effect of Sm is to drastically reduce the anisotropy strength, meaning that the preference for ⟨110⟩ vs ⟨100⟩ dendrites discussed in relation to Fig. 3 is small. The error bars are calc...

Although it may be difficult to quantify we found no evidence of image degradation caused by this intra-exposure jitter and we found this to be the limiting factor for the obtained 2D resolution, meaning that increasing the exposure time did not lead to a resolution better than 10 nm. The ...
