Using Adaptive Neuro Fuzzy Inference System to Predict Rate of Penetration from Dynamic Elastic Properties

Journal of Engineering, 2020
Rate of penetration plays a vital role in field development process because the drilling operation is expensive and include the cost of equipment and materials used during the penetration of rock and efforts of the crew in order to complete the well ...

Establishment and experimental verification of rock penetration load model for TBM disc cutters based on cavity expansion theory

Yantu gongcheng xuebao, 2022
The dynamic derivation of dense core at the cutter bottom seriously affects the rock-breaking mechanism of disc cutter (hereinafter referred to as cutter), and then affects the tunneling efficiency of full face rock tunnel boring machine (TBM) to a ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Vibration prediction and analysis of the main beam of the TBM based on a multiple linear regression model

Scientific Reports
The vibration of tunnel boring machine (TBM) is very difficult to monitor on sites, and related research on prediction methods is rare. Based on the field tunnelling test of a TBM in the Xinjiang Ehe project, the vibration information of the main beam of

Partial FAK suppression promotes tumor growth, an effect reversed by macrophage p110δ PI3K inactivation

Molecular Oncology, EarlyView.
Partial inhibition of focal adhesion kinase (FAK) can paradoxically promote tumor growth, rather than simply producing a weaker antitumor effect than that observed with strong FAK suppression. In breast cancer and melanoma models, targeting p110δ PI3K, particularly in macrophages, counteracted these tumor‐promoting effects, highlighting the importance ...

Metal magnetic memory quantitative inversion of defects based onoptimized support vector machine regression

工程科学学报, 2018
During welding processes, initial defects such as incomplete penetration and slag are easily generated. To ensure the safe operation of welding components, welded joints must be tested rigorously.

The effect of blanket system and port plugs on the harmonic components of error field and optimizing approach investigation

Nuclear Fusion, 2023
The fusion plasma is sensitive to the penetration of the toroidal mode numbers $n$ harmonic components of the error fields (EFs), and the toroidal mode components of the EFs are closely tied to the toroidal distribution of the magnetic field source.
