Theoretical analysis and design of fire protection and thermal insulation of parallel wire or strand cables
In this study, a transient heat flow model has been established for parallel wire or strand cables at high temperature by employing the lumped thermal mass approach, and the numerical solution of the surface temperature as a function of time in each layer of the steel wire or strand inside the…

Deep neural network‐based adaptive zero‐velocity detection for pedestrian navigation system
Abstract The zero‐velocity update (ZUPT) method is an effective way to reduce accumulated velocity errors of pedestrian navigation systems (PNSs). For a typical scheme, a stance phase detection module based on a fixed threshold is used to trigger the ZUPT algorithm. However, the detector is not…

NSUN2 restrains gastric cancer cell apoptosis and ferroptosis by promoting the m5C modification of EPYC
Abstract Background Epiphycan (EPYC) has been confirmed to play an oncogenic role in many cancers. However, its role and mechanism in gastric cancer (GC) progression has not been explored. Methods The levels of EPYC and NOP2/Sun domain 2 (NSUN2) were detected by qRT-PCR and western blot. Cell…

Fuzzy Neural Broad Learning System: Data-Driven Model Predictive Control for Shipboard Boarding Systems
Shipboard boarding systems operating under complex sea conditions are subject to vessel motion coupling, wave induced disturbances, strong nonlinearity, and engineering constraints, which make accurate end pose tracking difficult. Existing mechanism-based approaches often suffer from modeling…

A Hierarchical Cooperative Control Framework for Shipboard Boarding Systems Based on Dynamic Positioning Feedforward
Offshore wind turbine operation and maintenance in complex sea states is influenced by the coupled effects of low-frequency vessel drift and high-frequency wave-induced disturbances. In practical operations, the ship dynamic positioning system primarily regulates low-frequency motion through vessel…

Entity Recognition for Chinese Hazardous Chemical Accident Data Based on Rules and a Pre-Trained Model
Due to the fragile physicochemical properties of hazardous chemicals, the chances of leakage and explosion during production, transportation, and storage are quite high. In recent years, hazardous chemical accidents have occurred frequently, posing a great threat to people’s lives and property…

Analysis of the PM2.5–O3 Pollution Characteristics and Its Potential Sources in Major Cities in the Central Plains Urban Agglomeration from 2014 to 2020
To highlight the characteristics of PM2.5–O3 pollution in the Central Plains Urban Agglomeration, spatial and temporal characteristics, key meteorological factors, and source pollution data for the area were analyzed. These data from the period 2014–2020 were obtained from state-controlled…

Topic recognition method of comment text based on density Canopy
The method, which combines Sentence-BERT and LDA, takes the topic number of LDA as the k value in K-means algorithm, resulting in poor interpretability and low topic consistency. To solve this problem, a Sentence-BERT and LDA optimization method based on density Canopy(SBERT-LDA-DC) was proposed…

Experimental investigation of fire spread and eruption mechanism in canyons
Extreme fire behavior can lead to a transition from an initial low-intensity quasi-steady fire spread state to a new state with increased rates of spread (ROS) and burning intensity. Eruptive fire, a typical extreme fire behavior, occurs frequently in canyons. This study systematically conducted a…

A Refined View of Airway Microbiome in Chronic Obstructive Pulmonary Disease at Species and Strain-Levels
Little is known about the underlying airway microbiome diversity in chronic obstructive pulmonary disease (COPD) at in-depth taxonomic levels. Here we present the first insights on the COPD airway microbiome at species and strain-levels. The full-length 16S rRNA gene was characterized from sputum…
