Reliability Analysis of High-Pressure Tunnel System Under Multiple Failure Modes Based on Improved Sparrow Search Algorithm–Kriging–Monte Carlo Simulation Method

Applied Sciences
It is often difficult for a structural safety design method based on deterministic analysis to fully and reasonably reflect the randomness of mechanical parameters, while the traditional reliability analysis method has a large calculation cost and low ...

Modular Approach for Probabilistic Safety Assessment of Systems with Multiple Failure Modes

IFAC-PapersOnLine, 2015
Probabilistic safety assessment (PSA) becomes quite difficult for the complex systems with different failure modes that are represented by Markov processes characterized by a large number of states and transitions. In order to overcome the complexity of this problem, we propose to build the Markov processes corresponding to each failure mode separately

Thermostructural responses of carbon phenolics in a restrained thermal growth test [PDF]

The thermostructural response of carbon phenolic components in a solid rocket motor (SRM) is a complex process. It involves simultaneous heat and mass transfer along with chemical reactions in a multiphase system with time-dependent material properties ...

A study on modes of rock failure under uniaxial compression [PDF]

, 2014
Rock failure is a serious problem in rock engineering. Rock failure modes are complex and difficult. A comprehensive study on rock failure modes at laboratory scale is very important.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Proactive risk assessment of vincristine use process in a teaching and referral hospital in Kenya [PDF]

, 2018
Background: The chemotherapy use process is considered as potentially risky for cancer patients due to its complex process, use of agents with narrow therapeutic indeces, multiple drug use and use of potentially toxic compounds adding to morbidity and ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
