Summary: Glubam is a newly developed structural material with properties comparable to other wood-based materials. The use of FRP bar as reinforcement in structures is attractive due to its lightweight, high strength, and corrosion resistance. Pull-out tests of carbon FRP bars glued-in glubam revealed an increasing tendency of peak loads with various parameters. The study also proposed a design equation for estimating the pull-out strength of CFRP bars in glued-in glubam joints.

Summary: This study proposes an artificial intelligence-based method for optimizing the process parameters of a grinding robot using neural networks and a genetic algorithm. The trained neural networks are used to fit the quantitative relationships between the process parameters and the result of grinding surface roughness and grinding time, and then the non-dominated sorting genetic algorithm II is used to calculate the Pareto optimal process parameter combinations. The optimized process parameters achieved significant improvements in surface roughness and grinding time, validating the feasibility and effectiveness of the proposed method in practical manufacturing applications.

Summary: This study investigates the formation mechanism of tearing damages during end-face grinding of CFRP circular cell honeycomb and proposes suppression strategies. By analyzing the grinding force and tearing depth, it is found that the formation of tearing damages is related to the weak stiffness of thin walls and the radial grinding force. The radial grinding force and maximum tearing depth can be altered by changing the maximum undeformed chip thickness, grinding speed, feed rate, and offset ratio.

Summary: This study investigates the influence of tool geometries and process conditions on fiber pull-out formations, drilling forces, and hole quality parameters during the drilling process of quasi-isotropic CFRP laminates. Dry drilling experiments were conducted using tools with three different point angles and varying feed and spindle speed conditions. The results show that the feed condition and drill point angle affect the drilling forces and undeformed chip thickness, which in turn influence the fiber pull-out formation mechanisms. A higher point angle tool results in less fiber pull-out area but deeper fiber pull-outs, leading to higher surface roughness.

Summary: The near-surface mounted (NSM) carbon fiber-reinforced polymer (CFRP) strengthening method is efficient in strengthening aging or damaged concrete bridges. The authors propose a near-end enhanced embedded (NEEE) CFRP strengthening method to prevent end debonding failure and simplify construction. They investigate the interfacial bonding performance of horizontally embedded CFRP strips using single-lap shear test specimens and propose a bond-slip model to describe the interfacial bond behavior.

Summary: Natural fiber-reinforced composites are promising alternative materials for modern moderate-to-high-technology products, but their heterogeneous structure can cause processing defects. Drilling of composites is essential for assembly, but can lead to delamination damage and fiber pull-out. A new image processing method has been developed to characterize these defects and investigate the effects of drilling parameters on them.

Summary: This study isolated six natural recombinant strains of Marek's disease virus (MDV) from infected chickens in China. The researchers found that these strains resulted from recombination between a vaccine strain and a virulence strain. Two of the recombinant strains showed mild virulence and caused temporary damage to the immune organs of chickens.

Summary: Infectious bursal disease virus (IBDV) is a major threat to the poultry industry worldwide. This study found that vvIBDV infection leads to an increase in Ca2+ levels in the endoplasmic reticulum (ER) of B cells and upregulation of the ER Ca2+ sensor STIM1. Inhibiting STIM1 expression decreases ER Ca2+ levels and suppresses vvIBDV replication, while overexpressing STIM1 increases ER Ca2+ levels and promotes vvIBDV replication. Additionally, inhibiting CRAC channels reduces vvIBDV infection by blocking Ca2+ entry into the ER.

Summary: Recently, an atypical infectious bursal disease (IBD) caused by a novel variant infectious bursal disease virus (varIBDV) has emerged in immunized chicken flocks in East Asia, resulting in serious economic losses. This study revealed that varIBDV can partially evade the immune protection provided by existing vaccines against the persistently circulating very virulent IBDV (vvIBDV). The findings of this study are significant for the comprehensive prevention and control of the emerging varIBDV.

Summary: In this study, L55 and W69 of Tva were identified as the key amino acids mediating ALV-A entry. These amino acids were crucial for correct interaction with ALV-A gp85. Soluble Tva and huCD320 harboring L55 and W69 effectively blocked ALV-A infection. Furthermore, gene-edited cell lines targeting these two amino acids completely restricted ALV-A entry without affecting Cbl uptake.

It found that very virulent IBDV (vvIBDV) is fatal to chickens, novel variant IBDV (nVarIBDV) causes severe damage to the bursa of Fabricius and B lymphocytes, and attenuated IBDV (attIBDV) is non-pathogenic. The study is important for understanding the epidemiology, pathogenicity, and comprehensive prevention and control of IBDV strains.
