A central question in Hedgehog (Hh) signaling is how evolutionarily conserved components of the pathway might use primary cilium mammals but not fly. We focus on Suppressor fused (Sufu), a major Hh regulator mammals, and reveal that Sufu controls protein levels full-length Gli transcription factors, thus affecting production activators repressors essential for graded responses. Surprisingly, despite ciliary localization most components, regulation by cilium-independent. propose...
Summary The CRISPR/Cas9 and Cas12a (Cpf1) tools have been used on a large scale for genome editing. A new effector with single nuclease domain, relatively small size, low‐frequency off‐target effects cleavage capability under high temperature has recently established designated CRISPR/Cas12b (C2c1). Cas12b also shown inducibility in mammalian systems. Therefore, this system is potentially valuable editing the genomes of plant species, such as cotton, that are resistant to temperatures. Using...
Metallic materials are always suffered from the risk of combustion when serviced under some extreme conditions such as high temperature, oxygen-enriched enrichment, and high-speed friction. Although different mathematic models have been proposed but it is still a challenge for accurately describing ignition metals conditions, which great significance safety-use materials. In this paper, based on Semenov Frank-Kamenetskii theory were introduced into effects size, oxygen concentration,...
More than half of the world's population suffers from epidemic diseases that are spread by mosquitoes. The primary strategy used to stop mosquito-borne is vector control. Interference RNA (RNAi) a powerful tool for controlling insect populations and may be less susceptible resistance other strategies. However, public concerns have been raised because transfer antibiotic marker genes environmental microorganisms after integration into recipient genome, thus allowing pathogen acquire...
The height profile of information pits (or bumps) on the data surface an optical disk is assumed in most publications to be either rectangular or trapezoidal. Currently, when bumps are produced by using a photoresist technique, their inevitably rounded. Moreover, plastics molding practice, edge rounding and sloping sidewalls advantageous factors avoid sharp becoming damaged replica removed from mold. A new expression for obtained that provides convenient description geometry with different...
Abstract The substrate of a compact disk with data storage structure (pits and lands) on one side is part the read-out system. One would not expect optimum pit depth to be fixed value (a quarter wavelength, as customarily assumed) because this independent parameters optical wavelength based an inappropriate plane wave model. A model has been developed, interference converging spherical waves, for information disk. simple expression was found that gives dependence In different systems will,...
The problem in the design of zero-position reference marks for grating measurement systems is concerned with solutions a set quadratic equations derived from autocorrelations binary codes mark. author proposes method to linearise these equations. Results obtained can be used determine structure required autocorrelation coefficients.
High-accuracy shape sensing for composite structures is key to achieving deformation digital twin monitoring (DDTM) and, thereby, compliant assembly in producing aircraft, automobiles, and similar products. The inverse finite element method (iFEM) a material parameter-independent technology offering an effective approach DDTM of structures. However, unavoidable strain measurement noise limits iFEM's accuracy. To this end, paper proposes high-accuracy based on full-field corrected iFEM, which...
With the increasing awareness of environmental protection and prominent problem traditional energy, new energy vehicles are an important choice to replace oil-fueled vehicles. As part vehicles, design front face has impact on vehicles’ image, sales, brand awareness. A face’s modeling process is proposed in this paper based Kansei Engineering (KE)/ Rough Set Theory (RST)/ Backpropagation Neural Network (BPNN). Firstly, semantic analysis carried out including collecting samples words,...
Pore structure is a key parameter used to evaluate reservoir quality. At present, experimental method the most important analyze pore structure. However, coring data may be limited, and it not possible perform analyses on all cores. Therefore, researchers explored use of logging techniques study reservoirs. The relationship between geometry index (PGI), permeability mercury injection parameters was analyzed based experiment, thin slice analysis, production test well data. These results can...
This study investigates the combustion characteristics and critical thermodynamic conditions for ignition of TC4 TC17 alloys under high-speed friction conditions. The results indicate that, identical rubbing conditions, both pressure temperature alloy are higher than those alloy. increase with thickness, while they decrease increasing rotational speed, oxygen concentration, pressure. primary in initial stage abrasive adhesive wear. As duration increases, material from surface begins to peel...
The direct ink writing (DIW) process has been successfully used to prepare SiC-based composites from preceramic polymers due the porous light weight, lower sintering temperature, and tailored design. However, it still presents challenges in improving mechanical properties of endowing them with multifunctionality. In this study, we present a 3D-printing strategy for preparing graphene/SiCp/SiC composite using DIW process. A polycarbosilane (PCS)-based slurry containing graphene/SiCp powder...
Abstract Sulige gas field is the largest natural producing area in China. Due to “water blocking” effect, gas–water layer significantly influences development of reservoirs. The existence low‐resistivity layers He 8 member Shihezi Formation southwestern makes it challenging distinguish from using conventional identification methods. To effectively identify layers, their genetic mechanisms are analyzed by studying lithology and pore structural characteristics based on well logging core...

To investigate the effects of 17β-estrogen on expressions C-reactive protein (CRP) and its mRNA in vascular smooth muscle cells(VSMCs).Immunocytochemistry was used to detect CRP level normal VSMCs. The p-ERK1/2 Ang-II-stimulated VSMCs were evaluated with Western blot. examined RT-PCR.17β-estrogen had no effect cell morphology expression VSMCs; however, mRNA, as well decreased after treatment a concentration-dependent manner.17β-estrogen may inhibit via ERK1/2 signal transduction pathway way.
