Different from artistic style transfer,the challenge of photorealistic style transfer is to maintain the authenticity of the output while transferring the color style of the style input.Now,most photorealistic style transfer methods perform pre-proces-sing or post-processing based on artistic style transfer methods,to maintain the authenticity of the output image.However,artistic style transfer methods usually cannot make full use of global color information to achieve a more coordinated overall impression,and pre-processing and post-processing operations are often tedious and time-consuming.To solve the above problems,this paper establishes a photorealistic style transfer network guided by global information,and proposes a color-partition-mean loss(Lcpm) to measure the similarity of the global color distribution between output and the style input.Adaptive instance normalization(AdaIN) is improved,and partition adaptive instance normalization(AdaIN-P) is proposed to better adapt to the color style transfer of real images.In addition,this paper also introduces a cross-channel partition attention module to make better use of global context information and improve the overall coordination of output images.Through the above methods,the decoder of network is guided to make full use of global information.Experimental results show that,compared with other state-of-the-art me-thods,the proposed model can achieve a better photorealistic style transfer effect while maintaining image details.

In this paper, the scaled boundary finite element method (SBFEM) is first applied to the forced vibration analysis of partially liquid-filled composite laminated shell structure considering fluid–structure interaction. In comparison with the finite element method, the SBFEM only requires discretization of the boundary of the solution domain, which can reduce the spatial dimension of the problem by one and provide the radial analytical expressions for the variables within the solution domain. The structure consists of a multi-layered fiber-reinforced composite laminated shell and incompressible, inviscid, and irrotational liquid. After separately describing the basic expressions for the fluid and composite laminated shell, which includes the transformation of three coordinate systems and the establishment of the constitutive equations for the shell, the governing equations for the fluid and shell structure using the scaled boundary finite element method and modified SBFEM based on scaling surface transformation are formulated, respectively. Meanwhile, the Newmark method and synchronous solution algorithm are employed for the fluid–structure interaction analysis. Subsequently, two validation cases are conducted to assess the accuracy and convergence of the model. Finally, two numerical examples are employed to perform a parameter analysis on the model, involving the response of the system to ground horizontal harmonic excitation and seismic load. The results indicate that the SBFEM, as a semi-analytical high-precision numerical method, can be effectively used to simulate fluid–structure interaction problem of partially liquid-filled laminated composite shell structures.

The effect of N2-plasma-treated SiO2 interfacial layer on the interfacial and electrical characteristics of HfO2/SiO2/p-Si stacks grown by atomic layer deposition (ALD) was investigated. The microstructure and interfacial chemical bonding configuration of the HfO2/SiO2/Si stacks were also examined by high-resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS). Compared with the samples without N2-plasma treatment, it is found that the samples with N2-plasma treatment have less oxygen vacancy density for SiO2 interfacial layer and better HfO2/SiO2 interface. In agreement with XPS analyses, electrical measurements of the samples with N2-plasma treatment show better interfacial quality, including lower interface-state density (Dit, 9.3 × 1011 cm−2·eV−1 near midgap) and lower oxide-charge density (Qox, 2.5 × 1012 cm−2), than those of the samples without N2-plasma treatment. Additionally, the samples with N2-plasma treatment have better electrical performances, including higher saturation capacitance density (1.49 μF·cm−2) and lower leakage current density (3.2 × 10−6 A·cm−2 at Vg = Vfb − 1 V). Furthermore, constant voltage stress was applied on the gate electrode to investigate the reliability of these samples. It shows that the samples with N2-plasma treatment have better electrical stability than the samples without N2-plasma treatment. [ABSTRACT FROM AUTHOR]

This paper aimed to investigate the prevalence of diabetes mellitus (DM) and explore the associated risk factors in a very elderly southwest Chinese population. From September 2015 to June 2016, a cross-sectional survey was conducted to obtain a representative sample of 1,326 participants over 80 years old living in Chengdu. The presence of DM was based on fasting plasma glucose (FPG) and 2-h plasma glucose (2-hPG) levels during an oral glucose tolerance test (OGTT). A logistic regression model was used to calculate the odds ratios (OR s) and 95% confidence intervals (CI s) of the potential associated factors. The participants' mean age was 83.5 ± 3.1 years. The overall prevalence of DM was 27.4%. The prevalence was higher in males (30.2%) than females (24.7%) (P = 0.02). The prevalence of DM increased with body mass index (BMI) and decreased with aging. The multivariate analysis suggested that male sex (OR = 1.433; 95% CI , 1.116–1.843), hypertension (OR = 1.439; 95% CI , 1.079–1.936), overweight or obesity (OR = 1.371; 95% CI , 1.023–1.834), high heart rate (≥ 75 beats/min; OR = 1.362; 95% CI , 1.063–1.746), and abdominal obesity (OR = 1.615; 95% CI , 1.216–2.149) were all significantly positively correlated with DM. However, age was negatively correlated with DM (OR = 0.952; 95% CI , 0.916–0.989). The prevalence of DM and newly diagnosed DM in a very elderly southwest Chinese population was high. OGTT screening should be performed regularly in people aged ≥ 80 years to ensure timely diagnosis of DM. [ABSTRACT FROM AUTHOR]
