Summary: An upgraded infrared broadband trace gas detection configuration was investigated, utilizing specially designed T-resonators and simultaneous differential optical and photoacoustic measurement capabilities. By using acetylene and local air as samples, the detectivity of the differential photoacoustic mode was demonstrated to be far better than the pure optical approach. The wavelet domain denoising algorithm was introduced to greatly improve the signal-to-noise ratio, leading to a fivefold improvement in sensitivity to acetylene.

Summary: The world's biomass resources currently amount to around 170 billion tons, but biomass energy consumption only accounts for about 14% of the world's total energy consumption. Direct combustion of biomass raw materials and production of bio-natural gas are the two main methods for biomass utilization. This study collected 99 samples of 4 types of biomass materials from eight provinces of China and proposed a model for predicting biomass heat release using chemometric algorithms and deep learning.

Summary: Bones are a common site for metastasis from solid tumors, and current treatments are not curative. Near-infrared photoimmunotherapy (NIR-PIT), which uses antibodies labeled with IRDye700DX (IR700) activated by NIR light, has shown success in treating head and neck cancer but has not been tested on bone metastases. This study investigated the efficacy of EGFR-targeted NIR-PIT on bone metastatic lesions using a mouse model and found that it had a therapeutic effect and could repair metastasis-induced bone destruction.

Summary: Near-infrared photoimmunotherapy (NIR-PIT) is a novel molecularly-targeted therapy that selectively kills cancer cells by injecting an antibody-photoabsorber conjugate (APC) that binds to cancer cells, followed by the application of NIR light. NIR-PIT can selectively kill cancer cells without harming normal tissues and activates anti-cancer immunity.

Summary: This study proposes a novel method that combines improved complete ensemble empirical mode decomposition with adaptive noise and adaptive wavelet packet threshold denoising to reduce multipath error in GNSS-RTK measurements. The method decomposes the data, selects relevant components, and applies denoising techniques to improve the accuracy of the multipath error correction model. The results demonstrate that the proposed algorithm outperforms other filtering algorithms in terms of multipath error correction.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.
