Strong deflection gravitational lensing by a modified Hayward black hole

A modified Hayward black hole is a nonsingular black hole. It is proposed that it would form when the pressure generated by quantum gravity can stop matter’s collapse as the matter reaches the Planck density. Strong deflection gravitational lensing occurring nearby its event horizon might provide some clues of these quantum effects in its central core. We investigate observables...

Analysis of the Effect of 60Co-γ Irradiation Sterilization Technology on the Chemical Composition of Saffron Using UPLC and UPLC/Q-TOF-MS

To evaluate the effect of 60Co-γ irradiation sterilization technology on the chemical composition of saffron, we collected 10 batches of saffron samples and treated them with different irradiation doses. UPLC characteristic chromatogram showed that there was no significant effect of irradiation on 13 common peak areas. The results of cluster analysis and principal component...

Studies on a 2nth-order p-Laplacian differential equation with singularity

In this paper, we consider the 2nth-order p-Laplacian differential equation with singularity ( φ p ( x ( t ) ) ( n ) ) ( n ) + f ( x ( t ) ) x ′ ( t ) + g ( t , x ( t − σ ) ) = e ( t ) . By applications of coincidence degree theory and some analysis techniques, sufficient conditions for the existence of positive periodic solutions are established. MSC: 34C25, 34K13, 34K40.

Existence of periodic solution for generalized neutral Rayleigh equation with variable parameter

In this paper, we consider a generalized neutral Rayleigh equation with variable parameter ( x ( t ) − c ( t ) x ( t − δ ( t ) ) ″ + f ( t , x ′ ( t ) ) + g ( t , x ( t − τ ( t ) ) ) = e ( t ) , where | c ( t ) | ≠ 1 , c , δ ∈ C 1 ( R , R ) and c, δ are ω-periodic functions for some ω > 0 . By applications of coincidence degree theory and some analysis skills, sufficient...

Prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant: performance analysis and comparative study

Background This study investigated the prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant. The performance analysis and comparative studies of six materials for the prevention of stack corrosion were investigated. Results The ion chromatography analysis showed the acid condensation contained fluoride, chloride, nitrate...

MiR-20a Promotes Cervical Cancer Proliferation and Metastasis In Vitro and In Vivo

MicroRNAs (miRNAs) are small, non-coding RNAs that are critical regulators of various diseases. MicroRNA-20a (miR-20a) has previously significantly altered in a range of cancers. In this study, we detected the relationship between miR-20a and the development of cervical cancer by qRT-PCR, we found that the expression level of miR-20a was significantly higher in cervical cancer...

First detection of Candidatus Rickettsia barbariae in the flea Vermipsylla alakurt from north-western China

Background Vermipsylla is a genus of the family Vermipsyllidae within the order Siphonaptera of fleas. Vermipsylla alakurt is mainly distributed in alpine pastoral areas of Kazakhstan, Mongolia, China and Nepal, and infests sheep, yaks and horses, causing irritation, poor condition, anaemia and even death. However, to date, no rickettsial agents have been reported in V. alakurt...

Gene stacking in plant cell using recombinases for gene integration and nucleases for marker gene deletion

Background Practical approaches for multigene transformation and gene stacking are extremely important for engineering complex traits and adding new traits in transgenic crops. Trait deployment by gene stacking would greatly simplify downstream plant breeding and trait introgression into cultivars. Gene stacking into pre-determined genomic sites depends on mechanisms of targeted...

Thickness, porosity, and permeability prediction: comparative studies and application of the geostatistical modeling in an Oil field

Background In this study, we applied the geostatistical modeling to analyze an oil field. The reservoir properties, thickness, porosity and permeability, were studied. Data analysis tools, such as histogram, scatter plot, variogram and cross variogram modeling, were employed to capture the interpretable spatial structure and provide the desired input parameters for further...

Association between Time of Day of Sports-Related Physical Activity and the Onset of Acute Myocardial Infarction in a Chinese Population

Objective To investigate the association between the time of day of sports-related physical activity and the onset of acute myocardial infarction (AMI) in a coronary artery disease (CAD) population in China. Methods Between February 2014 and March 2015, a total of 696 patients from Nanjing, China, who had CAD were studied and divided into two groups (Non-AMI and AMI groups). The...

Discovery of Novel ncRNA Sequences in Multiple Genome Alignments on the Basis of Conserved and Stable Secondary Structures

Recently, non-coding RNAs (ncRNAs) have been discovered with novel functions, and it has been appreciated that there is pervasive transcription of genomes. Moreover, many novel ncRNAs are not conserved on the primary sequence level. Therefore, de novo computational ncRNA detection that is accurate and efficient is desirable. The purpose of this study is to develop a ncRNA...

A novel non-stop mutation in MSX1 causing autosomal dominant non-syndromic oligodontia

Oligodontia, which is the congenital absence of six or more permanent teeth, excluding the third molars, may contribute to masticatory dysfunction, speech alteration, aesthetic problems and malocclusion. Msh homeobox 1 (MSX1) was the first gene identified as causing non-syndromic oligodontia. In this study, we identified a novel heterozygous non-stop mutation (c.910_911dupTA, p...
