However, the efficacy of physical methods like Ultraviolet-C (UVC) radiation is often inconsistent due to poorly understood, pathogen-specific resistance mechanisms. To address this, we investigated the differential responses of cacao-infecting fungi (Colletotrichum gloeosporioides and the more resistant Pestalotiopsis sp.) to UVB (305 nm) and UVC (275 nm) radiation. We developed an integrated framework using quantitative morphology, hyperspectral imaging (HSI), and machine learning to dissect the physiological underpinnings of UV sensitivity. UVC proved significantly more potent than UVB; for example, a 4-min UVC exposure achieved a similar level of inactivation on a sensitive isolate as a 30-min UVB exposure. After 30 min of UVC, the resistant Pestalotiopsis sp. maintained an 89% survival rate, whereas C. gloeosporioides isolates were almost completely inactivated (< 8% survival). HSI revealed that this resistance correlated with physiological stability, while sensitive isolates exhibited significant biochemical disruption. Machine learning models successfully classified isolates based on their UV-induced phenotypes with over 73% accuracy. This understanding enabled targeted strategies, such as synergistic treatment with sonication, which overcame the high resistance of Pestalotiopsis sp.

Subsequently, we combined the AgNPs with engineered M13 bacteriophages (Li5 phage) displaying a foreign peptide that provides selectivity for specific E. coli strains. We found that the AgNP@Li5 phage molecular complex exhibited highly selective antibacterial activity against E. coli F+, F- and pathogenic O157:H7 strains while having little impact on other bacterial species (p < 0.0001). AgNPs@Li5 demonstrated antibacterial activity with similar MIC values for E. coli TG1 and E. coli F-, inhibiting bacterial growth at a 1:16 dilution. In contrast, the antibacterial activity against E. coli O157:H7 was lower, with a dilution value of 1:8, compared to the other E. coli strains. The specificity of this approach minimizes collateral damage to surrounding bacteria, addressing a key challenge in conventional antimicrobial therapies.

Although the effects of manure on paddy soil P fractions and availability have been extensively studied, different studies have yielded inconsistent results.

The results demonstrated that manure application increased the total, available, and microbial biomass P (MBP) by 46%, 134%, and 78%, respectively. The enhancing effect of manure on different P fractions followed the order of labile-P (221%) > moderately labile-P (145%) > stable-P (53%). Manure also significantly enhanced the activity of soil phosphatase, particularly that of alkaline phosphatase, by improving soil properties and enhancing microbial activities. In terms of manure types, pig manure could more significantly enhance the soil P availability and labile-P. Soil available potassium (AK), soil total nitrogen (TN), and mean annual temperature (MAT) were significant factors influencing soil P availability. Compared with non-fertilization treatments, manure amendments also significantly increased TP loss. Under application rates of 2-6 t ha<sup>- 1</sup> yr<sup>- 1</sup>, the runoff loss of TP (101%, 95% CI: 45 to 158%) was minimized.

A comprehensive 3D model is developed to incorporate the intermediate principal stress with Mogi Coulomb criterion to assess the impact of these reinforcement methods. Our findings suggest that the critical bolt reinforcement length ranges from [Formula: see text] (tunnel diameter) to [Formula: see text], significantly reducing extrusion deformation and enhancing tunnel stability. Pre-grouting improves the cohesion and strength of the surrounding rock, effectively preventing seepage and collapse. The safety factor obtained from the model calculations shows that SF increases with the increase of the intermediate principal stress coefficient, reaching its maximum value when the coefficient is 0.5, and then decreases.
