Dehydration of Biotissues During Their Compression [PDF]
Известия Саратовского университета. Новая серия: Физика, 2020 Background and Objectives: Dehydration of tissue is one of the possible mechanisms of mechanical tissue optical clearing. In this study we investigated the effects of dehydration of ex vivo cow muscle tissue samples during their compression on diffuse ...

Results in Optics, 2022 The use of the conventional Tauc’s method to determine optical bandgap energy from UV–vis spectroscopy data has been overemphasized for decades. However, a misuse of the Tauc’s formula in conjunction with the Kubelka-Munk function to determine the ...

CoRR, 2023 Score-based diffusion models learn to reverse a stochastic differential equation that maps data to noise. However, for complex tasks, numerical error can compound and result in highly unnatural samples. Previous work mitigates this drift with thresholding, which projects to the natural data domain (such as pixel space for images) after each diffusion ...

Partially Reflected Diffusion [PDF]
SIAM Journal on Applied Mathematics, 2008 The radiation (reactive or Robin) boundary condition for the diffusion equation is widely used in chemical and biological applications to express reactive boundaries. The underlying trajectories of the diffusing particles are believed to be partially absorbed and partially reflected at the reactive boundary; however, the relation between the reaction ...

In vivo diffuse reflectance spectroscopic analysis of fatty liver with inflammation in mice
Surgery Open Science, 2021 Background: Nonalcoholic steatohepatitis is a progressive liver disease that can lead to cirrhosis, hepatocellular carcinoma, and hepatic failure. Thus, the diagnosis of nonalcoholic steatohepatitis, especially discrimination from nonalcoholic fatty ...

Refraction and Reflection of Diffusion Fronts [PDF]
Physical Review Letters, 2003 Diffusion waves form the basis of several measurement technologies in materials science as well as in biological systems. They are, however, so heavily damped that their observation is a real challenge to the experimentalist. We show that accurate information about the refraction-like and reflection-like behavior of diffusion waves can be obtained by ...

Morphological and optical properties of porous hydroxyapatite/cornstarch (HAp/Cs) composites
Journal of Materials Research and Technology, 2020 This paper presents the correlation between the morphological characteristics and the diffuse reflectance (optical properties) of the porous hydroxyapatite/cornstarch (HAp/Cs) composites with various starch proportions (30, 40, 50, 60, 70, 80 and 90 wt%).
