Hepatocellular carcinoma （HCC） is a highly aggressive liver malignancy and the main form of liver cancer. Early diagnosis and treatment of HCC can effectively reduce mortality. Carboxylesterase （CE）-specific detection and imaging can be used for early diagnosis and image-guided surgical of HCC. However, traditional optical probes suffer from poor selectivity and low imaging signal-to-noise ratio. Here, we have constructed a series of chemiluminescent probes for carboxylesterase detection based on the strategy of enzymatic pocket-oriented steric tailoring techniques. The probes with different unique and excellent properties have been obtained through the structure-based steric hindrance adjustment on the recognition site. Here, CE-2 has been successfully used for high-throughput screening of rapid carboxylesterase inhibitors due to its extremely low detection limit (2.5×10-4U mL-1) and fast recognition ability. CE-3 has been successfully used for image-guided surgery of orthotopic hepatocellular carcinoma due to its ultra-long chemiluminescence imaging （over 12 h） of hepatocellular carcinoma. This study may promote advances in the rapid detection and screening of inhibitory drugs for CE and the field of surgical navigation in HCC.

In order to identify the tilt direction of the self-mixing interference (SMI) signals under weak feedback regime interfered by noise， a deep learning method is proposed. The one-dimensional U-Net (1D U-Net) neural network can discriminate the direction of self-mixing fringes accurately and quickly. For experimental SMI signals， the 1D U-Net can be used for discriminant direction after a one-step normalization. Simulation and experimental results show that the proposed method is suitable for SMI signals with noise within the whole weak feedback regime， and can maintain a high discrimination accuracy for signals interfered by 5dB noise. Combined with fringe counting method， accurate and rapid SMI signal displacement reconstruction can be realized.

Parabolic trough collector is a promising technology for both domestic and industrial heat supplies. To enhance the collector efficiency, a modified trough receiver with dozens of V-grooved light traps incorporated into its lower-half absorber was introduced. For assessing the performance of this receiver, a solar-thermal-stress coupled model was established. Using this model, firstly, the effects of the V-grooved light traps were investigated. The results reveal that, compared to the conventional trough receiver, the modified trough receivers equipped with different traps can reduce their optical losses by 81.9–138.0 Wm-1（i.e., 15.0%–25.2%）, improving their optical efficiencies by 1.60%–2.69%. However, these traps also result in increased thermal loss from the receiver. Therefore, there is no single optimal modified trough receiver that consistently outperforms all other receivers across all possible conditions. Nonetheless, the MTR30-3 and MTR60-3 receivers emerge as the optimized choices due to their better solar-thermal performance. Subsequently, performance evaluation reveals that the two optimized receivers can enhance the receiver efficiencies within the typical solar irradiance range by 0.02%–2.65% and 0.05%–1.70% when the inlet fluid temperatures are below 488 and 523 K, respectively. Consequently, the collector efficiencies can be improved by 0.02%–2.49% and 0.05%–1.60%, respectively. Additionally, thermal stress analysis verifies that the two optimized receivers remain within safe limits under all typical conditions. Given that the heating temperature of a typical solar collector for domestic or industrial heat supply is typically below 523 K, the integration of the two optimized receivers has the capability to effectively enhance the overall collector efficiency.
