Selective Internal Radiation Therapy (SIRT) is a widely used radioembolization method for treating primary liver cancer and malignant neoplasms in the liver. Tumor-Liver ratio (TLR) is an important dosimetric parameter for SIRT treatment using 90Y-microspheres. TLR can be calculated from liver and tumor segmentation attained from 99mTc-MAA SPECT/CT. In this study, we propose Multi-Scale Attention U-Net (MANet) and histogram adjustment for accurate liver and tumor segmentation of CT and fused SPECT/CT images, respectively. MANet introduces the multi-scale strategy network to learn and fuse various semantic features from different scales. Histogram adjustment is used for handle normal and abnormal histogram distribution. Noisy-Student pre-trained weights which is learned from noisy images by data augmentation is used in our work. This pre-trained model helps generalize our model and improve overall segmentation performance. 3DIRCADb-01 public dataset is used along with our MAA CT images collected from King Chulalongkorn Memorial Hospital (KCMH) for liver segmentation, and MAA SPECT/CT dataset is used for tumor segmentation. Our proposed method can accurately segment liver, and tumor with DSC of 0.87, 0.65 and IoU of 0.82 and 0.54 respectively.

Abstract—It is significant to optimize the efficiency and accuracy of operational modal analysis (OMA) in extreme operation. Modal parameters in thermal environments, especially complete operating deflection shapes (ODSs), was first reconstructed through an improved continuously scanning laser Doppler vibrometer (CSLDV) with a two-dimension scan (2D-S) scheme (CSLDV 2D-S) system. Before this work, the manual-moving laser Doppler vibrometer, which replaced heat resistant accelerometers, was used in thermal vibrational measurements to extract only a few dozens of measured points across the grid. Compared with a manual-moving laser Doppler vibrometer in thermal vibrational measurements, the CSLDV is able to sweep its laser spot along a scan path on the surface of a workpiece. An improved CSLDV 2D-S system is able to measure thousands of vibration points in a few seconds and reconstitute precise multi-ODSs through the demodulation method and arranging each single ODS according to the position of scan paths on the measured workpiece. Therefore, the complete ODSs can be meshed after interpolation, instead of rough mode shapes formed by the LDV.

In this paper, we present a new modulation scheme based on polynomial phase signals (PPS) for non-orthogonal multiple-access (NOMA) transceivers. The PPS leading to outstanding spectral efficiency are exploited to modulate the signal of users in the NOMA system. The demodulation procedure is performed by High-Order Ambiguity Function (HAF)-based successive interference cancellation (SIC). The performance evaluation, such as bit error rate (BER) and peak-to-averagepower ratio (PAPR) analysis of our new NOMA technique, is also demonstrated in this paper. Simulation results illustrate that the proposed scheme has the capability to increase the BER performance while suppressing the peak-to-average-power ratio (PAPR) compared to the traditional OFDM-based NOMA system or other existing modulation schemes.

Based on the CAPPI data of single grid point, this paper establishes the spatial consistency algorithm of adjacent radars, studies the spatial consistency of echo intensity on the equidistant line in the same observation area, and uses the radar data after strict quality control to study the horizontal consistency and vertical profile consistency of echo intensity on the equidistant line of adjacent radars, so as to verify the reliability of the spatial consistency algorithm. By analyzing the echo intensity of Zhoushan radar in Zhejiang Province, it is about 4dB lower than that of Hangzhou station and Ningbo Station, but the echo structure is relatively consistent. In order to realize the integration of spatial consistency algorithm on the national new generation weather radar business system, the national radar automatic matching program and contour plane automatic selection program are compiled, and the National Weather Radar spatial consistency evaluation standard is formulated, which makes it possible to evaluate the National Weather Radar Echo spatial consistency in real time. According to the trial operation effect of spatial consistency algorithm, it can detect the echo difference between adjacent radars in real time and efficiently, and give the evaluation results.

The behavior of people during an evacuation may have a significant impact on evacuation time, so it has been extensively studied using agent-based simulations. This paper aims to use machine learning for predicting agent evacuation time faster in advance, rather than waiting the entire simulation time. We use the well-known machine-learning polynomial regression as our prediction model, and linear regression and decision tree regression as our benchmark models. In order to generate a suitable dataset for training and validating our models, we automate the scenario-creation process from a single template scenario and the simulation output extraction process in the Vadere simulation framework. Our simulation experiments are carried out using the structure plan of the University of Münster's administrative building, with up to 100 agents located in a source room as individuals and in groups, attempting to find the shortest path to an exit. We significantly improve evacuation prediction using machine learning regression models in agentbased simulation experiments. Our polynomial regression model can predict evacuation time before the simulation begins, and the prediction results are close to the simulation results, with an average R2 score of 84%

This article presents a 2:1 analog multiplexer (AMUX) for a digital preprocessed analog-multiplexed digital-to-analog converter (DP-AM-DAC) in optical transmitter, which can generate a 160 GBaud (320 Gb/s) four-level pulse-amplitude modulation (PAM-4) signal. The AMUX was designed in 0.13μm BiCMOS technology that contains bipolar devices based on SiGe:C NPN-heterojunction bipolar transistor's (HBT's) with up to 300 GHz transient frequency and 500 GHz oscillation frequency. The AMUX with fully differential configurations, consisting of two data input buffers, a three-stage polyphase filter, two clock input buffers, an AMUX core, and an output buffer, occupies an area of 1.143×1.078 mm2 and consumes 1.52-W from 5 V and 6 V supplies. This AMUX could meet the requirements of the 160 GBaud class systems by using the SiGe BiCMOS technology that has low cost and can be integrated with CMOS compared with the InP HBT-designed AMUX.

Time reversal (TR), as an effective technique of multipath utilization, has been applied to radar signal processing. However, due to the complex and changeable multipath environment, there is no quantitative analysis of multipath channels and TR echo. In this paper, we construct a typical multipath signal model and further study the time reversal echo on this basis. Subsequently, the relationship between the number of multiple propagation paths and the TR echo is analyzed. The results demonstrate the efficiency of TR technology for multipath utilization and applicable scenarios, which provides a basis for popularizing the application of TR technology.
