PROPOSAL TO DEFINE AN EXACT VALUE FOR THE GRAVITATIONAL CONSTANTRonald Sherrod
A class of radiative solutions of Einstein's field equations with a negativecosmological constant and a pure radiation is investigated. The space-times,which generalize the Defrise solution, represent exact gravitational waveswhich interact with null matter and propagate in the anti-de Sitter universe...
which is predominantly employed to manage heat transfer complications adequately. In this day and age, the acquisition of sufficient temperature control for ultrasensitive equipment throughout numerous industrial operations like thermal insulation, nuclear plants, fiber coating, heat exchangers, and...

Con- sidering the low-energy sector of Hoˇrava gravity as a viable Lorentz-violating gravity in four dimensions which admits a different speed of gravity, we find the exact rotating black hole solutions (with or without cosmological constant). We find that the singular region extends to r <...

(t_i\). Note that in many practical scenarios as found in deep learning, the loss\(l_V\)depends only on the state of a constant number of neurons, irrespective of network size. If\(l_V\)depends on the voltage of non-firing readout neurons, we have\(l_V^+ = l_V^-\)and the...
As the form of the effective action (8) holds for any kind of unparticle, let us pro- ceed without specifying the coupling constant κ∗, and insert eq.(10) only in the final result. Our main purpose is to solve the field equations derived from S by assuming the source is static, ...
Turning to the proof of (2.7), consider the function p(x) ≡ w(x) −u(x) . Since p(1) =0, and since u(x)w(x) −u(x)w(x) is equal to a constant for all x, we have p(x) =− u(1)w(1) u(x) 2 <0, ...
Since our conditions (2.41), (2.45) come from the requirement that no branch points of the potential are included in the parallelogram, it would be interesting to establish a direct connection between the forces generated by the branch points and the gravitational instability. It would be ...
