Optics Express, 2022 An instrument named as Volume Scattering and Attenuation Meter (VSAM) is presented. The VSAM can simultaneously measure the attenuation coefficient and the volume scattering function (VSF) from 10° to 170° with an interval of 10° at 659 nm. Using ultrapure water and NCRM-traceable polystyrene microsphere beads, the VSAM was calibrated, and the ...

Molecular Oncology, EarlyView.Pair‐wise comparison of the CellSearch and FETCH enrichment technologies for circulating tumor cells (CTCs) from metastatic breast, prostate, and small cell lung cancer patients shows an increased capture of CTCs using FETCH enrichment. The clinical implementation of circulating tumor cells (CTCs) as a predictive tool for therapy efficacy in the ...

Quality Assessment of Phase Functions for Volume Rendering in Biomedical Applications
JISR on Computing– The volume rendering algorithm is used for the conversion of three-dimensional data into images that are coherent for visualization, where the phase function has a pivotal position in controlling the scattering of light in the medium.

Continuous energy adjoint transport for photons in PHITS
EPJ Web of Conferences, 2017 Adjoint Monte Carlo can be an effcient algorithm for solving photon transport problems where the size of the tally is relatively small compared to the source. Such problems are typical in environmental radioactivity calculations, where natural or fallout

Optimizing optical flow cytometry for cell volume-based sorting and analysis. [PDF]
PLoS ONE, 2011 Cell size is a defining characteristic central to cell function and ultimately to tissue architecture. The ability to sort cell subpopulations of different sizes would facilitate investigation at genomic and proteomic levels of mechanisms by which cells ...

Volume scattering function, average cosines, and the underwater light field [PDF]
Limnology and Oceanography, 1991 The extent to which the relationship between the apparent optical properties of water bodies Kd,, R(0) (vertical attenuation coefficient, reflectance) and inherent optical properties of the water (a, b, bb,—absorption, scattering, backscattering coefficients) varies with the shape of the volume scattering function has been investigated via Monte Carlo ...

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Lensless imaging based on coherent backscattering in random media
AIP Advances, 2014 We studied lensless imaging due to coherent backscattering in random media both theoretically and experimentally. The point spread function of the lensless imaging system was derived.

An investigation into the particle volume scattering function variability in a cascading reservoir system [PDF]
Modeling Earth Systems and Environment, 2016 This work analyzed the spectral and spatial distribution of the particle volume scattering function, βp, in a cascading reservoir system. During fieldworks water quality parameters and scattering data were sampled in a predetermined stations. The βp was estimated using the ECO-BB9 equipment that measures the volume scattering function, β at 117° [β(117°

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
