Janus heterostructures consisting of multiple jointed components with distinct properties have gained growing interest in the photoredox catalytic field. Herein, we developed a facile low-temperature method to gain anisotropic one-dimensional Au-tipped CdS (Au-CdS) nanorods (NRs), followed by assembling Ru molecular co-catalyst (RuN
Introduction: Permeability is one of the most important parameters for reservoir evaluation. It commonly measured in laboratories using underground core samples. However, it cannot describe entire because limited number cores. Therefore, petrophysicists use well logs to establish empirical equations estimate permeability. This method has been widely used conventional sandstone reservoirs, but not applicable tight reservoirs with low porosity, extremely permeability, and complex pore...
Abstract Vitellogenin (Vg) is a source of nutrition for embryo development. Our previous study showed that the silkworm ( Bombyx mori ) transcription factor broad complex isoform 2 (BmBrC‐Z2) regulates gene expression Vg BmVg by induction with 20‐hydroxyecdysone (20E). However, mechanism which 20E was not clarified. In this study, cell transfection experiments promoter containing POU homeodomain POUM2 (POUM2) and BrC‐Z2 cis ‐response elements (CREs) more significant response to than...
Abstract Oestrogen‐related receptor (ERR) is involved in oestrogen (ER) signalling pathways owing to its similarity ER terms of domain structure and co‐activator response elements. Although insects lack ER, they harbour an ERR gene that thought modulate metabolism energy conversion via unknown mechanism. The present study investigated the function using female silkworm ( Bombyx mori , Bm). We found expression B. vitellogenin (BmVg) (BmERR) fat bodies silkworms at different stages development...
There can be no industrial oil production in tight reservoirs until fracturing is undertaken. Under such conditions, the brittleness of rocks a very important factor. However, it has so far been difficult to predict. In this paper, selected study area Lucaogou formation, Permian, Jimusaer sag, Junggar basin. According transformation dynamic and static rock mechanics parameters correction confining pressure, an improved method proposed for quantitatively predicting via well logs reservoirs....
BACKGROUND: The incidence of kidney tumors is progressively increasing each year. precision segmentation for crucial diagnosis and treatment. OBJECTIVE: To enhance accuracy reduce manual involvement, propose a deep learning-based method the automatic kidneys in CT images. METHODS: proposed comprises two parts: object detection segmentation. We first use model to detect position kidney, then narrow range, finally an attentional recurrent residual convolutional network RESULTS: Our achieved...
The performance of rolling bearing can directly affect the reliability a rotating machine. Due to influence noise and irrelevant components, fault information is rather weak in fault, which adds difficulty judgment state identification types. To solve problem heterogeneous feature caused by jamming failure, extracting feature, misdiagnosis misjudgment, paper has proposed denoising algorithm according covariance matrix Hankel entropy (Hankel-Cov-IE). First, signals constructed, are...
The resistivity index is an important parameter for determining the rock saturation index. However, changes greatly in unconventional reservoirs, which leads to oil estimation with great difficulty. Hence, we try establish relationship between and log data. Firstly, a novel model of estimating <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <msub> <mrow> <mi>T</mi> </mrow> <mn>2</mn> </msub> </math> time was derived based on fractal theory, nuclear magnetic resonance (NMR) id="M2">...
Due to the physical characteristics of ultrasonic imaging, there are many factors in process which lead low quality imaging images. There may be artifacts, noise interference, unclear edge contour diseased tissue, and other problems. This paper designs implements an image processing system for medical ultrasound images based on MATLAB GUI. The realizes functions enhancement, segmentation, filtering, detection, morphological Through detection breast duct images, interference is greatly...
The relationship between resistivity index and water saturation (I-Sw) is very important in formation evaluation via petrophysical data. Low permeability complicated pore structure make it more difficult to determine I-Sw through rock's electrical property measurements. Nuclear magnetic resonance (NMR) logs are alternative ways obtain these key parameters. To establish a model estimate from NMR logs, 17 cores the study area were selected for experiments. helium porosity, air permeability, T2...
Abstract When natural cracks in oil & gas development of tight sandstone remain valid, effective crack degree is the decisive factor reservoir enrichment and high production. Taking Bashijiqike Formation Kuqa depression, Tarim Basin as an example, parameters were characterized by a mathematical model algorithm, which lays theoretical foundation for study validity. According to processed electric imaging static modulus date rock mechanics, control conditions that constrain such...
