At each point x [member of] L, let us denote the time-like region of past as TPL(x), time-like region of future as TFL(x) and the 4-dimensional
ball of radius t as B(x, t).
In , the author has probed the shock wave geometry with mutual information in the 4-dimensional
plane symmetric Reissner-Nordstrom AdS black branes.
As it has been said previously, besides these spaces (whose group of isometries has dimension 6) the class of homogeneous three-space with 4-dimensional
group of isometries provides also nice examples of Killing submersions with both K and [tau] being constant.

computed tomography: Comparison with pulmonary function tests and SPECT ventilation images," International Journal of Radiation Oncology Biology Physics, vol.
Figure 4 shows an example of building the UB-Layer with the 4-dimensional
Equation (23) is 4-dimensional
map of the tendency of the flutter speed for various plates' dimensions.
Consequently, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] in Steps 4 and 5 are matchings in 4-dimensional
subcubes K([Q.sup.0]) and K([Q.sup.1]), respectively, of sizes not exceeding 8/2 = 4.
So I have borrowed at least one useful concept from the philosophers: the 4-dimensional
block universe model of spacetime, which fruitfully complicates the texture of historicist approaches by recognizing each point's indivisible combination of distinct matter, time, and space.

Let ([bar.M], [bar.g], [PHI], V) be a 4-dimensional
The model assesses the radiative forcing associated with 4-Dimensional
(4D) trajectories in a 4D weather field, encompassing both the local time-of-day and the contrail lifetime.
The same applies to the simulations for 4-dimensional
geometry: the numerically obtained value u [approximately equal to] 3.3 [+ or -] 0.1 is slightly more than the expected value of u = 2[pi]/[pi]-1, but less than u = 4, which corresponds to the isotropic four-dimensional geometry.
