The diffusion profile of phosphorus can be described as consisting of three regions : the high concentration region, the transition region ( kink of the profile ) the l 45、ow concentration region ( the tail region ) v Fairs vacancy model In high concentration region, P+ pairs with V2- as...
The amount of signal loss is related to the displacement distribution of the spins and the applied gradients and can be described as e-bD. b is called the b-value and describes the magnitude and duration of the applied diffusion gradients according to b=-γ2G2δ2Δ-δ/3, where G is ...
In addition, other structures, such as unmyelinated axons, glia cell, and blood vessels, may have nontrivial contributions to the (time-dependent) diffusion signal and can be added to the numerical microgeometry. Ultimately, a large human EM sample32 (comparable to MRI voxel size), prepared ...
Using the reparameterization trick (see derivation here) the random variable xₜ can be equivalently described as:where ϵₜ₋₁ is d-dimensional standard Gaussian noise. This formula reveals that the more noisier image xₜ is a weighted average between the less noisier image xₜ...
This has been described as the diffusion of innovation or the adoption process. Adoption is concerned with the way that a consumer becomes a regular customer for a new product concept. Diffusion refers to the way in which the product penetrates its potential market, which, in turn, suggests ...
As we look under the hood, the first observation we can make is that there's a text-understanding component that translates the text information into a numeric representation that captures the ideas in the text. 当我们深入研究的时候,我们首先发现有一个文本理解组件,它将文本信息转换为数字表示,从而...
where αt αt¯ can be described as αt :=∏S=1tαs,αt=1−βt.αt¯:=∏S=1tαs,αt=1−βt. (4) The reverse process of the model is a Markov chain with learnable parameters θθ. The inverse process uses the Mel spectrogram, y, as a regulator. Since it is diff...
(c) setting the stage for the future study of broad-scale adoption of the concept. Diffusion of Innovations can be described as “the process by which an innovation is communicated through certain channels over time among members of a social system [21].” Stages through which innovations ...
This model allows for image variations and mixing operations as described in Hierarchical Text-Conditional Image Generation with CLIP Latents, and, thanks to its modularity, can be combined with other models such as KARLO. Comes in two variants: Stable unCLIP-L and Stable unCLIP-H, which are ...
When adoption decisions are strongly influenced by a single actor, such as a national government, the diffusion curve may deviate from the S-shape. For example, diffusion can be exponential when the required information for adoption is broadcasted instead of transferred from users to non-users ...
