Summary: The study found that different operational regimes appear in a swirling gas-solid fluidized bed with increasing superficial velocity. In a stable swirling regime, particles tend to be centrifugally attached to the wall, accompanied by strong elutriation. Additionally, reducing the central body height helps decrease bed pressure drop and swirling velocity. The increase in operating velocity is beneficial for particle mixing behaviors in a swirling bed with a lower central body.

Summary: Ferrography is an important method for detecting wear particles in mechanical equipment. The deposition behavior of wear particles in a ferrograph, considering the magnetic, fluid, and solid fields, was studied using the finite element method. The particle force and deposition principle were analyzed, and a theoretical deposition law was obtained. A 3D finite element model was created to simulate the particle tracking and study the effects of oil pressure, viscosity, density, slide inclination angle, distance between oil tube and slide, and particle release mode on the deposition behavior. Experimental results verified the accuracy of the numerical simulation.

Summary: The genomic architectures of 505 bladder cancer patients from Asian/Black/White populations were analyzed, revealing an unknown association between AHNAK mutations and APOBEC-a mutational signature activity. The prevalence of TP53 and ATM clonal mutations as well as the burden of SCNAs is significantly higher in Whites/Blacks than in Asians. A trans-ancestry prognostic subtype of bladder cancer was identified, characterized by enrichment of non-muscle-invasive patients and muscle-invasive patients with good prognosis, specific mutations, decreased intra-tumor heterogeneity and genome instability, and an activated tumor microenvironment.

Summary: The transport properties of moisture and ionic chelators in concrete have a significant impact on both the durability of the concrete and the effectiveness of repair materials for cracks. Capillary absorption tests and ICP-OES were used to investigate the transport of water and ionic chelators in concrete. It was found that smaller capillary pores take longer to reach saturation with water, leading to the square root shift phenomenon of capillary water absorption. Higher initial concentrations facilitate the transport of ion chelators in a certain depth range, but the effect diminishes beyond that range. Chelated ions form aggregation zones during transport, which promotes the repair of pores and cracks in concrete.

Summary: The effects of water-to-fly ash ratio, class C fly ash content, and sand-to-ash ratio on the workability, mechanical properties, and chloride resistance of fly ash-based geopolymer mortars were investigated. Three different strength grades of geopolymer mortars were chosen for chloride resistance tests, and the weight change, ultrasonic flight-time, and compressive strength were measured. The results showed that high class C fly ash content, low water-to-fly ash ratio, and low sand-to-ash ratio resulted in low fluidity and high compressive strength of the specimens. The low-strength samples exhibited excellent chloride resistance after corrosion.

Summary: The study aimed to investigate the therapeutic role of Triptolide, a traditional Chinese medicine, against tibial dyschondroplasia (TD) in chickens. The results showed that the symptoms of TD group were improved, and tibial parameters were changed after triptolide treatment. In addition, the expression of m-TOR and P62 mRNA in the triptolide treatment group showed a significant decrease compared to the TD group. Triptolide was found to have protective effects against TD by inhibiting hypertrophic chondrocytes apoptosis and autophagy induced by thiram.

Summary: This paper proposes an evidence network reasoning recognition method based on a cloud fuzzy belief, which takes advantage of the evidence network in uncertainty processing. The method constructs a hierarchical structure model of an evidence network, measures the degree of correlation between nodes using the MIC method, generates beliefs based on the cloud model, and realizes target recognition under uncertain conditions through evidence network reasoning. Simulation results demonstrate that the proposed method can handle random uncertainty and cognitive uncertainty simultaneously, overcome the limitation of traditional methods in hierarchical recognition, and effectively utilize sensor information and expert knowledge for deep cognition of the target intention.

Summary: In this study, a compound library of FDA approved drugs was screened and desloratadine, an antiallergic drug, was found to inhibit the proliferation of hepatocellular carcinoma (HCC) cells. NMT1 was identified as the target protein of desloratadine and its upregulation promoted HCC growth, while NMT1 inhibitors showed anti-tumor effects. Furthermore, NMT1-mediated N-myristoylation modification was found to play a crucial role in HCC progression, and desloratadine disrupted this process by inhibiting NMT1 activity.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
