Enhancing active fire detection in Sentinel 2 imagery using GLCM texture features in random forest models.

The array of wildfire activities instigated by human endeavors has emerged as a significant source of atmospheric pollution, posing considerable risks to both public health and property safety. This study harnesses Sentinel-2 satellite data, employing a variety of methods including spectral index methods, thresholding, and the Random Forest (RF) model for active fire spot detection. The research encompasses a wide range of land cover types across various Chinese regions.

Wood-Derived Continuously Oriented Three-Phase Interfacial Channels for High-Performance Quasi-Solid-State Alkaline Zinc Batteries.

Although recently developed hybrid zinc (Zn) batteries integrate the benefits of both alkaline Zn and Zn-air batteries, the kinetics of the electrocatalytic oxygen reaction and mass transfer of the electrolyte, which are limited by the mismatched and disordered multiphase reaction's interfacial transfer channels, considerably inhibit the performance of hybrid Zn batteries. In this work, novel, continuously oriented three-phase interfacial channels at the cathode derived from the natural structure of pine wood are developed to address these challenges. A pine wood chip is carbonized and asymmetrically loaded with a hydrophilic active material to achieve the creation of a wood-derived cathode that integrates the active material, current collector, and continuously oriented three-phase reaction interfacial channels, which allows the reaction dynamics to be accelerated.

Study of Se/Te-doped CuO as a hole transport material in perovskite solar cells.

Theoretically, cuprous oxide (CuO) is a particularly excellent potential material, for the hole transport layer (HTL) of perovskite solar cells (PSCs). However, the photoelectric conversion efficiency (PCE) of its experimental samples is still not ideal. The main reasons for this include the material, and inherent and interface defects of CuO, but this can be improved by doping.

Introduction: To analyze the current state, hotspots, and cutting-edge trends of genomics research on the outbreak of Corona Virus Disease 2019 (COVID-19) from 2019 to the present (March 2022).

Methods: Statistical and visual analysis of COVID-19 genomics results published in the 2019-2022 Web of Science Core Collection Database (WOSCC) was performed using CiteSpace software, including data on countries, institutions, authors, journals, co-citations, keywords, etc.

Results: A total of 9133 English literature were included.

[Clinical Features and Risk Factors of Systemic Lupus Erythematosus Complicated with Cytomegalovirus Infection].

Objective To explore the clinical characteristics and risk factors of systemic lupus erythematosus(SLE)complicated with cytomegalovirus infection(CMV). Methods The medical records of patients diagnosed with SLE at discharge in the Department of Immunology at Peking Union Medical College Hospital between July 1,2017 and April 1,2019 were retrospectively reviewed,and the clinical and laboratory data related to CMV infection were analyzed. Results Of the 231 patients with SLE,115(49.

Auxiliary interferometer in an optoelectronic swept-frequency laser and its application to the measurement of the group refractive index.

An optoelectronic swept-frequency laser (SFL) is an optoelectronic feedback system that includes an auxiliary interferometer that can exert precise control over the optical frequency sweep. The arm-length difference (ALD) of the auxiliary interferometer directly affects the performance of the whole system. We established a theoretical model to choose the optimal ALD of an auxiliary interferometer in an optoelectronic SFL system using a frequency-modulated continuous-wave reflectometry experimental setup.

[Clinical and Laboratory Characteristics of Disseminated Non-tuberculous Mycobacterial Disease].

Objective To explore the clinical and laboratory characteristics and the prognosis of disseminated non-tuberculous mycobacteria(NTM)diseases in human immunodeficiency virus(HIV)negative patients. Methods Cases of disseminated NTM disease were retrospectively collected in Peking Union Medical College Hospital from January 2012 to October 2018.Clinical manifestations,laboratory findings,treatment,and prognosis of these cases were retrieved from the electronic medical record system.

Molecular cloning and spatiotemporal expression of -like gene in .

(), a floral meristem identity gene controls the flowering time and floral transition, and plays an important role in inflorescence and floral organ development. The full-length cDNA for was obtained by rapid amplification ofthe cDNA ends (RACE) so that the roles of in (Lm-AP1) could be better understood. (accession number in GenBank: MF418642) consisted of a 729-bp open reading frame encoding a protein that contained 242 amino acids, had a deduced molecular mass of 27.

[Comparison on fungal molecular ecological networks of agricultural soils with different latitudes in the black soil region of Northeast China].

To investigate the differences of fungal network structures and interaction among fungal species of in black soil region of Northeast China, Illumina MiSeq sequencing was used to reveal the fungal communities in the three long-term fertilization experimental fields. Fungal molecular ecological networks were constructed based on random matrix theory (RMT). The results demonstrated that Ascomycota, Basidiomycota and Zygomycota were the dominant phyla and Hypocreales, Pleosporales and Sordariales were the dominant order, but the relative abundance of some dominant taxa significantly varied in different locations.

The Risk Factors of Acquiring Severe Hand, Foot, and Mouth Disease: A Meta-Analysis.

Objectives: The incidence of severe hand, foot, and mouth disease (HFMD) is not low, especially in mainland China in almost every year recently. In this study, we conducted a meta-analysis to generate large-scale evidence on the risk factors of severe HFMD to provide suggestions on prevention and controlling.

Methods: PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang (Chinese) were searched to identify relevant articles.

[Imaging and audiology analysis of the congenital inner ear malformations].

Objective: To investigate imaging and audiology features of temporal bone and analyze the classification and prevalence of inner ear abnormalities in children with sensorineural hearing loss.

Method: Children who were diagnosed with sensorineural hearing loss were examined by high resolution CT and the inner ear fluid of MRI. And each chart was retrospectively reviewed to determine the imaging and audiology features.

Response inhibition of cigarette-related cues in male light smokers: behavioral evidence using a two-choice oddball paradigm.

Behavioral inhibitory control has been shown to play an important role in a variety of addictive behaviors. A number of studies involving the use of Go/NoGo and stop-signal paradigms have shown that smokers have reduced response inhibition for cigarette-related cues. However, it is not known whether male light smokers' response inhibition for cigarette-related cues is lower than that of non-smokers in the two-choice oddball paradigm.
