Background： Murine model of coronary arterial inflammation has been widely accepted as an animal model of and used in Kawasaki disease （KD）. This study sought to evaluate the developmental changes of coronary arteries and cardiac function in a murine model of KD with a high-frequency ultrasound system and to provide evidence for the preparation of the model of KD. Methods： Lactobacillus case~ cell wall extract was prepared and injected into C57BL/6 mice intraperitoneally （i.p.） to induce KD. A total of 120 mice were grouped into three groups. The intravenous immunoglobulin （IVIG） treatment group was i.p. injected with IVIG （2 g/kg）, while the KD model and normal control groups were i.p. injected with 0.5 ml of phosphate buffered solution on day 5. All high-resolution echocardiography detection of mouse heart was performed by the same senior technician. Animal echocardiography was performed by measuring the coronary artery dimensions and cardiac function on days 0, 7, 14, 28, and 56 （high-resolution small animal ultrasound [Vevo770 pattem; VisualSonic, Canada] with broadband probe [RMVTM707B; frequency, 30 mHz; depth of focus, 1.2 cm]） which were measured and analyzed with Vevo770 software. Results： Pathological studies revealed focal inflammatory infiltrate asymmetrically distributed around the coronary artery trunk in the KD model group. Echocardiographic study including coronary dimension and cardiac function measurements was successfully performed in all subjects. The KD model and IVIG treatment groups showed left coronary artery dilation on days 7, 14, 28, and 56. The diameter of left coronary artery in the KD model group （0.53 ± 0.09 mm; 0.36 ± 0.07 mm; 0.34 ±0.05 mm; 0.34±0.04 mm） was significantly larger than those of 1VIG treatment group （0.22± 0.02 mm; 0.28 ± 0.03 mm; 0.26± 0.03 mm; 0.27 ±0.05 mm; 0.26 ± 0.03 mm; all P〈 0.01） and the normal control group （0.21 ±0.02 mm; 0.22 ±0.03 mm; 0.22± 0.02 mm; 0.23 ± 0.02 mm; 0.27± 0.04 mm; all P 〈 0.01） on days 7, 14

To improve the quality of the illumination distribution， one novel indoor visible light communication (VLC) system， which is jointly assisted by the angle-diversity transceivers and simultaneous transmission and reflection-intelligent reflecting surface (STAR-IRS)， has been proposed in this work. A Harris Hawks optimizer algorithm (HHOA)-based two-stage alternating iteration algorithm (TSAIA) scheme is presented to jointly optimize the magnitude and uniformity of the received optical power. Besides， to demonstrate the superiority of the proposed strategy， several benchmark schemes are simulated and compared. Results showed that compared to other optimization strategies， the TSAIA scheme is more capable of balancing the average value and variance of the received optical power when the maximal ratio combining (MRC) strategy is adopted at the receiver. Moreover， as the number of the STAR-IRS elements increases， the optical power variance of the system optimized by TSAIA scheme would become smaller while the average optical power would get larger. This study will benefit the design of received optical power distribution for indoor VLC systems.

A two-dimensional numerical irregular wave tank based on the potential wave theory was developed. A source term was used inside the domain to generate waves, and outgoing waves were dissipated by sponge layers and transmitted by radiation boundary. The σ-coordinate transformation was introduced to map the time-dependent irregular physical domain to a fixed regular computational domain, and thus the free surface and bottom boundary conditions could be implemented precisely. The model was verified by simulating the nonlinear regular and irregular wave propagation on constant-depth water, as well as regular waves reflected from a vertical wall, and satisfactory agreement between numerical results and analytical solutions was obtained. The present numerical model is proved to be an effective tool for a long-duration simulation of coastal wave dynamics where the wave reflection is significant.
