Webb10 mars 2024 · In this letter, we show that quantum gravity leads to lower and upper bounds on the masses of dark matter candidates. These bounds depend on the spins of the dark matter candidates and the nature of interactions in the dark matter sector. For example, for singlet scalar dark matter, we find a mass range . The lower bound comes … Webb17 maj 2024 · As for the upper bound, each permutation can be represented as a corresponding characteristic set and then we apply some methods from extremal set theory to obtain an upper bound of a new type, which beats the sphere-packing type bound when d is relatively close to n. The rest of this paper is organized as follows.

It is an application of the Visa mer Comparison of Shannon's capacity to Hartley's law Comparing the channel capacity to the information rate from Hartley's law, we can find the effective number of distinguishable levels M: Visa mer • Nyquist–Shannon sampling theorem • Eb/N0 Visa mer During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the context of the telegraph as a communications system. At the time, these concepts were … Visa mer 1. At a SNR of 0 dB (Signal power = Noise power) the Capacity in bits/s is equal to the bandwidth in hertz. 2. If the SNR is 20 dB, and the bandwidth available is 4 kHz, which is appropriate for telephone communications, then C = 4000 log2(1 + 100) = 4000 log2 … Visa mer • On-line textbook: Information Theory, Inference, and Learning Algorithms, by David MacKay - gives an entertaining and thorough … Visa mer in action logo
