Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

The impact of misregistration on SRTM and DEM image differences

Remote Sensing of Environment, 2008
Abstract Image differences between Shuttle Radar Topography Mission (SRTM) data and other Digital Elevation Models (DEMs) are often performed for either accuracy assessment or for estimating vegetation height across the landscape. It has been widely assumed that the effect of sub-pixel misregistration between the two models on resultant image ...

Comparison of different drag models in CFD-DEM simulations of spouted beds

Powder Technology, 2020
Abstract Spouted beds are commonly simulated through the Computational Fluid Dynamics – Discrete Element Method approach. The choice of the drag model is still a matter of debate, as they feature peculiar operative conditions. In this work, we simulated two spouted beds containing Geldart-D particles.

New Cell for DEMS Applicable to Different Electrode Sizes

Electrocatalysis, 2011
Present approaches to use simple crystal electrodes for DEMS have certain disadvantages: Thin layer cells with defined diffusion and/or convection require large single discs of 1 cm diameter; also, a part of the crystal surface has to be pressed against a spacer. Other approaches, which allow the use of small bead crystals, have the disadvantage of ill-

Uncertainty of SWAT model at different DEM resolutions in a large mountainous watershed

Water Research, 2014
The objective of this study was to enhance understanding of the sensitivity of the SWAT model to the resolutions of Digital Elevation Models (DEMs) based on the analysis of multiple evaluation indicators. The Xiangxi River, a large tributary of Three Gorges Reservoir in China, was selected as the study area.

Discussion on the Difference of the Grain Particle Parameters in Reality and DEM

2016
The discrete element method was widely used in analyzing mechanics and movement behaviors of grain particle in recent years. An application of the method in the field of grains was presented in this paper. The experiment and simulation about the angle of corn indicates that the particle shape cannot be ignored in discrete element simulations, as well ...

Multi-Scale DEM Generalization Processing in Different Landform Areas

Advanced Materials Research, 2013
As a special kind of image, the grid-based digital elevation model (DEM) is directly related with the landform and topography feature. In the real word, there are various landforms, and the results of different methods for DEM processing vary greatly. However, the discussion of using different methods in different landform areas in DEM generalization ...
