Risk prediction of coal and gas outburst

, 2022
In order to solve the problems of low accuracy and slow response speed of existing support vector machine (SVM)-based coal and gas outburst prediction methods, a risk prediction method of coal and gas outburst based on improved grey wolf optimizer (IGWO)

Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

Animal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

Periodic outburst floods from an ice-dammed lake in East Greenland [PDF]

, 2017
We report evidence of four cycles of outburst floods from Catalina Lake, an ice-dammed lake in East Greenland, identified in satellite imagery between 1966–2016.

Construction and evaluation of a chronic arthritis animal model induced by persistent activation of toll‐like receptors via lipopolysaccharide stimulation

Animal Models and Experimental Medicine, EarlyView.
We constructed a novel systemic juvenile idiopathic arthritis mouse model (LC) by introducing sustained TLR4 activation into the collagen‐induced arthritis model. The LC model effectively recapitulates human sJIA‐like systemic inflammation while revealing a critical dissociation between systemic immune activation and joint damage.

Comprehensive outburst prevention technology of outburst-prone coal seam uncovered by crossdrift in Hongshan coal mine

, 2019
Coal and gas outburst is a complex geo-dynamic disaster induced by a coal seam uncovered by crossdrift, threatens the safety and efficient production of coal mines seriously. For this, Hongshan coal mine was selected as engineering background to simulate

Growth Differentiation Factor 15 as a Cerebrospinal Fluid Biomarker for the Diagnosis and Prognosis of Leptomeningeal Metastasis

Annals of Neurology, EarlyView.
Objective As leptomeningeal metastasis (LM) has a poor prognosis, reliable cerebrospinal fluid (CSF) diagnostic biomarkers are urgently needed. This study evaluated the diagnostic value of CSF growth differentiation factor 15 (GDF15) in LM from lung adenocarcinoma (LUAD) and breast cancer (BC).

A review on coal and gas outburst prediction based on machine learning

Meitan xuebao
The safety in the coal-producing mines in China is continuously improving, but coal and gas outburst accidents still occur. The prediction of coal and gas outbursts allows the scientific application of outburst prevention measures, which can ensure the ...

Mechanisms for Dwarf Nova Outbursts and Soft X-ray Transients [PDF]

, 1996
I review models trying to explain dwarf-nova outbursts and soft X-ray transients. The disc-instability model for dwarf-novae is still in its preliminary state of development: its predictions depend very strongly on the unknown viscosity mechanism. It is also doubtful that a {\sl pure} disc-instability phenomenon will be able to describe {\sl all} types
