Ionizing radiation and volumetric mammographic density

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2022
Objectives Mammographic density (MD) refers to the percentage of dense tissue of an entire breast and was proposed to be used as a surrogate marker for breast cancer.

High-density volumetric super-resolution microscopy

open access: yesNature Communications, 2023
Volumetric super-resolution microscopy typically encodes the 3D position of single-molecule fluorescence into a 2D image by changing the shape of the point spread function (PSF) as a function of depth. However, the resulting large and complex PSF spatial

High‐Density Lignin‐Derived Carbon Nanofiber Supercapacitors with Enhanced Volumetric Energy Density [PDF]

open access: yesAdvanced Science, 2021
Supercapacitors are increasingly used in short‐distance electric transportation due to their long lifetime (≈15 years) and fast charging capability (>10 A g−1).

Volumetric mass density measurements of mesenchymal stem cells in suspension using a density meter

open access: yesiScience, 2023
Summary: To use regeneratively active cells for cell therapeutic applications, the cells must be isolated from their resident tissues. Different isolation procedures subject these cells to varying degrees of mechanical strain, which can affect the yield ...

High Volumetric Energy Density Sulfur Cathode with Heavy and Catalytic Metal Oxide Host for Lithium–Sulfur Battery

open access: yesAdvanced Science, 2020
For high‐energy lithium–sulfur batteries, the poor volumetric energy density is a bottleneck as compared with lithium–ion batteries, due to the low density of both the sulfur active material and sulfur host.

Volumetric Density-Equalizing Reference Map with Applications [PDF]

open access: yesJournal of Scientific Computing, 2021
The density-equalizing map, a technique developed for cartogram creation, has been widely applied to data visualization but only for 2D applications. In this work, we propose a novel method called the volumetric density-equalizing reference map (VDERM) for computing density-equalizing map for volumetric domains.

Evaluation of post-liquefaction volumetric strain of reconstituted samples based on soil compressibility

open access: yesSoils and Foundations, 2021
In this study, we performed undrained cyclic–torsional–shear tests on clean and silty sands to examine post-liquefaction volumetric strain. Accordingly, we proposed a novel density index—ultimate volumetric strain—to evaluate the density of clean sand ...

Gradient-domain volumetric photon density estimation [PDF]

open access: yesACM Transactions on Graphics, 2018
Gradient-domain rendering can improve the convergence of surface-based light transport by exploiting smoothness in image space. Scenes with participating media exhibit similar smoothness and could potentially benefit from gradient-domain techniques. We introduce the first gradient-domain formulation of image synthesis with homogeneous participating ...

Volumetric breast density evaluation using fully automated Volpara software, its comparison with BIRADS density types and correlation with the risk of malignancy

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Mammography is currently the modality of choice for mass screening of breast cancer, although its sensitivity is low in dense breasts. Besides, higher breast density has been identified as independent risk factor so it has been conceptualized ...
