single particle diffusion/ A0550 Lattice theory and statisticsIsing problems A0560 Transport processes: theoryFollowing our previous works on lattice diffusion, and on the use of the local mean field method to describe diffusion in interacting lattice gases, we show that the latter can be also ...
What is the definition of diffusion? The movement of molecules from an area of their low concentration to their high concentration The movement of molecules across the cell membrane The movement of molecules from an area of their high concentration to their low concentration ...
The diffusion and nutrient consumption are represented using partial differential equations. This model predicts that onset of necrosis occurs when the concentrations of vital nutrients are below critical values, and also the overall tumor growth based on the size effects of the proliferation zone, ...
记sθ(z;λ)为得分模型(score model),我们用该模型来估计得分∇zlogqt(z),具体训练目标我们在下一节介绍。如果模型训练得足够好,可以完美完成估计任务,即有sθ(z;λ)=∇zlogq
lack of charge facilitates diffusion of molecules into the nonpolar organic solvent and enhances efficiency of extraction. For the selection of an optimal extraction pH, knowledge of the pKa value of the analyte is very helpful. Cpx pKa values are 8.80 for nitrogen in the piperazinyl ring and 6....
he found that the current measured at the electrode is independent of the H+concentration. He suggested that the reaction occurs at the outer Helmholtz plane and the local concentration at this site is different than in the bulk. He also suggested that the driving force for the electron transfe...
Rendered using Stable Diffusion This generated image of a finch demonstrates how AI can render a generic but very accurate image even without additional descriptors. However, the rendering on the right demonstrates how AI image generators, in this case, Stable Diffusion, can work with more elemen...
Here we test this hypothesis by measuring the mechanical properties of protein L, a domain with a topology predicted to be mechanically strong, but with no known mechanical function. A pentamer of this small, topologically simple protein is resistant to mechanical deformation over a wide range of...
It is known that MAGs have antimicrobial activity, which is stronger than their corresponding FFA, so due to the microbial resistance to conventional antimicrobials, interest has been developed toward new natural agents with little or no toxicity, such as the case of lipids and especially MAGs, be...
Chaos, or exponential sensitivity to small perturbations, appears everywhere in nature. Moreover, chaos is predicted to play diverse functional roles in living systems. A method for detecting chaos from empirical measurements should therefore be a key co
