Experimental Study on Single-Particle Combustion Characteristics of Large-Sized Wheat Straw in a Drop Tube Furnace by Haoteng Zhang, Lihui Yu, Cuina Qin, Shuo Jiang, Chunjiang Yu

“…Employing a two-mode experimental setup in a drop tube furnace (DTF) system simulating pulverized coal boiler conditions, we systematically investigated the combustion behavior and alkali metal release characteristics of this large-sized straw biomass, with combustion processes summarized for diverse particle types. The findings reveal asynchronous combustion progression across particle surfaces due to heterogeneous mass transfer and gas diffusion; unique behaviors distinct from denser woody biomass, including bending deformation, fiber branching, and fragmentation, occur; significant and morphology-specific deformations occur during devolatilization; fragmentation universally produces particles of varied shapes (needle-like, flaky, blocky, semi-tubular) during char combustion; and potassium release exceeds 35% after complete devolatilization and surpasses 50% at a burnout degree exceeding 80%. …”

Hyaluronidases improve the hyaluronic acid yield during the fermentation of Streptococcus zooepidemicus by Chuan-Li Kang, Chuan-Li Kang, Chuan-Li Kang, De-Qiang Zheng, De-Qiang Zheng, De-Qiang Zheng, Zhi-Yuan Yao, Kang Yang, Yuxue Zhao, Zihan Mao, Yang Liu, Haijun Li, Jin-Song Gong, Lei Liu, Qingwen Jia, Qingwen Jia, Zheng-Hong Xu, Zheng-Hong Xu, Jin-Song Shi, Le Xue

“…By administering HAase at intervals corresponding to viscosity thresholds, HA titers reached 10.3 g/L, representing a 14.4% increase over baseline.ConclusionThese findings demonstrate that HAase application alleviates viscosity-associated bottlenecks in S. zooepidemicus fermentations, establishing an optimized process for scalable HA production. This approach balances enzymatic degradation with microbial growth kinetics, offering a practical strategy for industrial HA biosynthesis.…”

Radio frequency fingerprint data augmentation for indoor localization based on diffusion model by Haojun AI, Weike ZENG, Jingjie TAO, Jinying XU, Hanxiao CHANG

“…The radio frequency fingerprint indoor localization method ensures the accuracy by collecting a sufficient amount of fingerprints in the offline state to build a dense fingerprint database.A data augmentation method called FPDiffusion was proposed based on diffusion model to reduce the cost of fingerprint acquisition.Firstly, a temporal graph representation of the fingerprint sequence was constructed, the forward process of the diffusion model was accomplished by adding Gaussian noise, and a U-Net was utilized for the reverse process.The loss function of the network was designed according to the characteristics of radio frequency fingerprints.Finally, the computational process for generating dense fingerprints based on sparse fingerprints was presented.Experimental results demonstrate that FPDiffusion achieves 76% and 28% localization error reduction on K-nearest neighbor (KNN) and convolutional neural network (CNN) respectively, and significantly improves localization accuracy on KNN compared to Gaussian process regression (GPR) and GPR-GAN when only a small amount of labeled fingerprints is available.…”
