Prediction of residual surface fatigue life of power transmission gears using X-ray diffraction method

Nihon Kikai Gakkai ronbunshu, 2019
A new technique using a non-destructive inspection to predict the residual surface fatigue life of power transmission gears has recently attracted interest. This technique is advantageously applied to the preventive maintenance of a vehicle transmission,

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

A synergistic arched lattice-honeycomb sandwich metastructure: Balancing impact resistance and thermal management

Materials & Design
Simultaneous enhancement of impact resistance and heat dissipation remains a critical bottleneck in the design of advanced metastructures. Drawing on inspiration from arch bridges, this work proposes a multifunctional sandwich metastructure.

Shunting passenger trains: getting ready for departure [PDF]

, 2008
In this paper we consider the problem of shunting train units on a railway station. Train units arrive at and depart from the station according to a given train schedule and in between the units may have to be stored at the station.

On-the-Fly Training

, 2004
A new algorithm for the incremental learning and non-intrusive tracking of the appearance of a previously non-seen face is presented. The computation is done in a causal fashion: the information for a given frame to be processed is combined only with the one of previous frames.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

Molecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...
