Infrasound signal classification is vital in geological hazard monitoring systems. The traditional classification approach extracts the features and classifies the infrasound events. However, due to the manual feature extraction, its classification performance is not satisfactory. To deal with this...

This case report describes a 16-year-old male patient who presented with bilateral peg-shaped lateral incisors, Class II Division 1 incisors and a Class II buccal occlusion. The patient chose to remove the peg-shaped lateral incisors and have the anterior spaces closed using clear aligners. The trea...

This paper investigates a stochastic semi-parametric SEIR model characterized by infectivity during the incubation period and influenced by white noise perturbations. First, based on the theory of stochastic persistence, we derive the conditions required for the disease to persist within the model....

A diagnostic technique based on independent component analysis (ICA), fast Fourier transform (FFT), and support vector machine (SVM) is suggested for effectively extracting signal features in infrasound signal monitoring. Firstly, ICA is proposed to separate the source signals of mixed infrasound so...

Traditional approaches for predicting the remaining useful life (RUL) of gearboxes often face challenges in integrating physical and virtual data, leading to reduced prediction accuracy and an increased risk of system failure. To realize reliable RUL prediction of gearbox, this paper proposes a nove...

In this study, we examined the occurrence of acquired and transmitted drug resistance to integrase strand transfer inhibitor (INSTI) in HIV-1 strains in Chongqing (China) for guiding for the routine testing of INSTI-associated HIV-1 genotype resistance. Plasma samples were obtained from HIV-1 patien...

The emergence of HIV drug resistance seriously affects the quality of life of patients. However, there has been no extensive study of CSF resistance. The aim of this study is to evaluate common HIV-1 resistance in CSF and compare it with resistance in matched plasma, and analyse the influencing fact...

Eriochloa villosa (Thunb.) Kunth, 1829 (Woolly cupgrass), an invasive annual weed in the Poaceae family, poses a significant threat to corn and soybean crop production, resulting in substantial yield reduction. Despite its agronomic importance, genomic resources for this species remain limited. In t...

Impact and protection are hot topics of concern in modern military and civilian fields. However, existing research focuses more on high-speed, high-frequency impact, explosion, and other loading conditions, while studies on the protective mechanisms and stress-deformation processes of materials duri...

The effectiveness and longevity of amendments will influence the reduction in cadmium (Cd) bioavailability by in situ remediation techniques. Different amendments, including red mud (RM), corn straw (CS), rape straw (RS), and their combinations with zinc (Zn) fertilizer, were evaluated based on a lo...

Root zone restriction, an efficient cultivation technique in grape production, alters the morphology and function of both the root system and the above-ground parts. The xylem serves as a crucial conduit connecting the root system to the above-ground structures, facilitating the transport of water...

In a continuous catalytic reforming (CCR) unit, a heating furnace tube located upstream of the reactor was cracked and leaked after 11 a of service. The cracking causes of the heating furnace tube were analyzed by chemical composition, tensile property at room temperature, tensile property at high t...

In this study, using Congo red staining method and enzyme activity assay, the high-yield cellulase fungi from soil samples in Turpan area was screened. The screened strain was identified by morphological observation and molecular biology techniques, and the enzymatic characteristics of cellulase pro...

To investigate the debonding protocols used by orthodontists in New Zealand.

Determining the appropriate soil cadmium (Cd) criteria for vegetable production is important for ensuring that the Cd concentrations of the vegetables meet food safety standards. The soil extractable Cd criteria for vegetable production are also essential for both food safety and environmental manag...

A field plot experiment in a calcareous soil with wheat and maize rotation was carried out for 2 yr. The study aimed to investigate the effects of biosolids (sewage sludge or chicken manure) application on nitrogen (N) and phosphorus (P) accumulation in soils and to develop a model for the effects o...

ObjectiveFat-soluble vitamins (FSVs) play essential roles in numerous physiological processes and are involved in the onset and progression of chronic diseases. However, limited research has investigated whether dietary intake of live microbes correlates with circulating FSVs levels. This study aims...
