Screening for lung cancer: A systematic review of overdiagnosis and its implications

open access: yesMolecular Oncology, EarlyView.
Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Cutting Force Prediction in Drilling of Titanium Alloy

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Cutting force in drilling of Ti-6Al-4V is studied with simulation based on a predictive model. In the force model, three-dimensional chip flow is made by piling up the orthogonal cuttings in the planes containing the cutting velocities and the chip flow ...

Forces and Plastic Work in Cutting

open access: yesCIRP Annals, 1983
Prolific considerations in C.I.R.P. give rise to a further step in the development of a plastic cutting model. Basically two different primary shear zone geometries are assumed: with one and with two shear planes respectively. For both geometries two energetically different approaches are developed.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

DEM simulation of soil-tool interaction under extraterrestrial environmental effects [PDF]

open access: yes, 2017
In contrast to terrestrial environment, the harsh lunar environment conditions include lower gravity acceleration, ultra-high vacuum and high (low) temperature in the daytime (night-time).
