ACCURACY INCREASE OF TURBINE RUNNER POSITIONING WITH FRICTIONAL CONTACT PROPERTIES

Advanced Engineering Research, 2011
The processes occurring in the friction units of the turbine runner with the fine positioning are considered. The method for increasing positioning accuracy with allowance for the frictional contact properties in the mathematical model describing the ...

Design of a 3D space early warning system for high precision positioning technology of Beidou and analysis of differential positioning accuracy

Measurement: Sensors
The Beidou satellite navigation system has achieved certain results in positioning accuracy, but due to factors such as system errors, its accuracy still does not fully meet the requirements of high-precision measurement. Therefore, this study proposes a

A Novel KGP Algorithm for Improving INS/GPS Integrated Navigation Positioning Accuracy. [PDF]

Sensors (Basel), 2019
The fusion of multi-source sensor data is an effective method for improving the accuracy of vehicle navigation. The generalization abilities of neural-network-based inertial devices and GPS integrated navigation systems weaken as the nonlinearity in the ...

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...

Improving the Shearer Positioning Accuracy Using the Shearer Motion Constraints in Longwall Panels

IEEE Access, 2020
The shearer positioning method with an inertial navigation system (INS) is feasible in a longwall mining face. However, INS error greatly increases with time, which reduces the shearer positioning accuracy.

Feasibility of a ctDNA multigenic panel for non‐small‐cell lung cancer early detection and disease surveillance

Molecular Oncology, EarlyView.
Plasma‐based detection of actionable mutations is a promising approach in lung cancer management. Analysis of ctDNA with a multigene NGS panel identified TP53, KRAS, and EGFR as the most frequently altered, with TP53 and KRAS in treatment‐naïve patients and TP53 and EGFR in previously treated patients.

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

Molecular 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 ...
