Predicting UHMWPE wear: evidence for rapid decline in wear rates following a change in sliding direction [PDF]

, 2009
Extending the service life of total joint replacements by improving the wear resistance of UHMWPE remains a priority that is driven by the demands of a more active patient [1].

Influence of contact pressure and sliding speed dependence on the tribological characteristics of an activated carbon-epoxy composite derived from palm kernel under dry sliding conditions

Friction, 2018
The objective of this work is to investigate the influence of contact pressure and sliding speed on the coefficient of friction and wear of an activated carbon-epoxy composite derived from palm kernel under dry sliding conditions.

Rate dependence of AE activity during frictional sliding [PDF]

Geophysical Research Letters, 2002
A velocity‐step test was performed to examine effects of the macroscopic sliding‐rate on AE activity during steady‐state frictional sliding on a pre‐cut fault in a granite sample. Both the amplitude‐frequency relation and the number of AE events per unit displacement changed in response to a change in the macroscopic sliding‐rate.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Rating Quantitative and Mapping of Sliding of the Quarry of Ouenza, Algeria

Physics Procedia, 2011
AbstractThe exploitation of iron ore deposit of Ouenza runs into serious difficulties related to landslides. Among the most important events of sliding, we have those of the site “Zerga” including lands located above the ore body “north” of Zerga. The overall area of the landslide is 40,000 m2.

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

Molecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.
