From Fick’s first law, the diffusion coefficient D can be defined as the rate of transfer of the diffusing substance across unit area and unitary concentration gradient of the diffusing substance. From this definition, it can be shown that the diffusion coefficient has units of length2/time, ...
This situation captures the concept of temporal lag, which is defined as the temporal interval that is needed for the outcome event to appear starting from the occurrence of the source event. But, if the second event happened a long time after the first event, they may be indirectly ...
Recently with the increasing cultural diffusion has been recognized as a tendency of___owing to___Linguistic imperialism is a kind of___whichcan be defined as the promulgation of global ideologies through the worldwide expansion of one language.相关知识点: 试题...

If the above process can be reversed and sampled from q(xt−1|xt), the true sample will be able to recreate from a Gaussian noise input xT∼N(0,I). Note that if βt is small enough, q(xt−1|xt) will also be Gaussian. The reverse diffusion process is defined as a Markov ...
(SC). It is defined as one minus the ratio between the specularly reflected acoustic energy and the total reflected acoustic energy.In other words, it shows how much energy is scattered from a reflection due to the uneven surface. The higher the number the more energy is scattered. ...
Though waves in translucent samples are not randomized, the transmission matrix can still be defined and the scaling of the x n can be computed in simulations in the translucent as well as the diffusive regime. We find a common structure for the x n with the x n remaining equally spaced ...
one has to pass `negative_prompt_embeds`. instead. If not defined, one has to pass `nega...
The standard policy gradient objective requires the gradient of the log-likelihood, which is only implicitly defined by the underlying Ordinary Differential Equation (ODE) of the diffusion model. Ren, Allen Z., et al."Diffusion Policy Policy Optimization."arXiv preprint arXiv:2409.00588 (2024). ...
Slower sorbate reorientation inside zeolites can be studied with 1D and 2D exchange NMR techniques [90]. The success of these types of studies depends on the presence of well-defined NMR interactions with large anisotropy, such as the 2H quadrupolar interaction in deuterated sorbates or the ...
