The ZSM-22 and ZSM-35 zeolites were synthesized via the hydrothermal crystallization method. The samples were characterized by XRD, SEM, N_2 adsorption-desorption, NH_3-TPD, TPO, TG, and Raman spectrometry, and the results showed that ZSM-22 and ZSM-35 possessed similar microporous volume and acidity. In the alkylation of benzene with methanol, ZSM-22 and ZSM-35 showed different coke location, coking rate and graphitizing degree. Compared with the industrial ZSM-5, ZSM-22 and ZSM-35 both showed higher selectivity of toluene and xylene(93.63% and 96.50%,respectively) during the alkylation of benzene with methanol, and the selectivity of para-xylene in xylene isomers was51.96% and 41.45%, respectively. Meanwhile, the selectivity of ethylbenzene and C_9^+ aromatics was also lower than that of industrial ZSM-5.

Small gold nanorods(AuNRs),namely AuNRs with less than 10 nm in diameter,possess a high absorption-to-scattering ratio,a large surface area-to-volume ratio,as well as high cellular uptake behaviors.In this study,we systematically investigate seedless synthesis of AuNRs with diameters ranging from 5 nm to 10 nm.It has been found that several experimental conditions,including the chain length of the used cationic surfactants,and the concentrations of ascorbic acid,NaBH4,and AgNO_(3)can profoundly affect the obtained products.Under optimal conditions,the production yields of the obtained several AuNRs with different diameters can exceed 90%and even reach almost 100%.The conversion of gold precursors to AuNRs was estimated to be 70%–77%as measured by absorption spectroscopy and inductively coupled plasma mass spectrometry.

Background Fatty liver hemorrhage syndrome(FLHS)becomes one of the most major factors resulting in the laying hen death for caged egg production.This study aimed to investigate the therapeutic effects of Lactiplantibacillus plan-tarum(Lp.plantarum)FRT4 on FLHS model in laying hen with a focus on liver lipid metabolism,and gut microbiota.Results The FLHS model of laying hens was established by feeding a high-energy low-protein(HELP)diet,and the treatment groups were fed a HELP diet supplemented with differential proportions of Lp.plantarum FRT4.The results indicated that Lp.plantarum FRT4 increased laying rate,and reduced the liver lipid accumulation by regulating lipid metabolism(lipid synthesis and transport)and improving the gut microbiota composition.Moreover,Lp.plan-tarum FRT4 regulated the liver glycerophospholipid metabolism.Meanwhile,“gut-liver”axis analysis showed that there was a correlation between gut microbiota and lipid metabolites.Conclusions The results indicated that Lp.plantarum FRT4 improved the laying performance and alleviated FLHS in HELP diet-induced laying hens through regulating“gut-liver”axis.Our findings reveal that glycerophospholipid metabolism could be the underlying mechanism for the anti-FLHS effect of Lp.plantarum FRT4 and for future use of Lp.plantarum FRT4 as an excellent additive for the prevention and mitigation of FLHS in laying hens.

Big Data Mining and Analytics 2024年第1期7卷 87-106页

With the enhancement of data collection capabilities,massive streaming data have been accumulated in numerous application scenarios.Specifically,the issue of classifying data streams based on mobile sensors can be formalized as a multi-task multi-view learning problem with a specific task comprising multiple views with shared features collected from multiple sensors.Existing incremental learning methods are often single-task single-view,which cannot learn shared representations between relevant tasks and views.An adaptive multi-task multi-view incremental learning framework for data stream classification called MTMVIS is proposed to address the above challenges,utilizing the idea of multi-task multi-view learning.Specifically,the attention mechanism is first used to align different sensor data of different views.In addition,MTMVIS uses adaptive Fisher regularization from the perspective of multi-task multi-view learning to overcome catastrophic forgetting in incremental learning.Results reveal that the proposed framework outperforms state-of-the-art methods based on the experiments on two different datasets with other baselines.

The CoVID-19 pandemic that started in late 2019 is sweeping through the world,posing historic challenges to global health,and disrupting social and economic lives.Previous and recent studies indicate that monoclonal antibodies can be efficacious in preventing and treating SARSCoV-1 and SARS-CoV-2 infections.Using a phage display platform,we have identified dozens of monoclonal antibodies that bind to diverse epitope groups on the SARS-CoV-2 spike protein.Many of them bound to the receptor binding domain(RBD)and inhibited ACE2-RBD interaction.
