Summary: This article discusses the adversarial attack problem faced by deep neural networks and the limitations of existing solutions. An approximated gradient sign method using differential evolution is proposed to solve the black-box adversarial attack problem. By transforming the pixel-based decision space into a dimension-reduced decision space and introducing different neighbor selection and optimization search strategies, multiple variants of the proposed method are developed. Experimental results demonstrate the superior performance of the method in solving black-box adversarial attack problems.

Summary: The study compared the effects of corn steep liquor and conventional chemical fertilizer on the growth and yield of bok choy in hydroponic systems. It found that in summer cultivation, using the same nitrogen amount of OF and CF resulted in similar yields but slower growth in OF, while using double the nitrogen in OF significantly inhibited growth. Although potassium, calcium, and magnesium content did not differ among treatments, the carbon/nitrogen ratio and nitric acid and ascorbic acid content varied significantly.

Summary: This study investigated the metabolic response of bok choy to chromium stress, revealing the inhibitory effect on plant growth and development, blockage of certain metabolic pathways, and accumulation of citric acid. The results provide insights into the mechanisms of heavy metal accumulation/tolerance in plants.

Summary: In this study, two fungal strains, FLP7 and B9, were isolated from the rhizosphere microbiome of Choy Sum and barley, identified as Penicillium citrinum. The results showed that the B9 strain significantly promoted the growth of Choy Sum plants in normal soil and under phosphate-limiting conditions. The presence of gibberellins and cytokinins in the culture filtrates of P. citrinum could explain the growth induction in Choy Sum plants.

Summary: In this study, camel-derived nanobodies recognizing cyantraniliprole and chlorantraniliprole were successfully generated, leading to the development of ELISA assays for detection of these insecticides. The ELISA results showed that chlorantraniliprole had higher concentrations than cyantraniliprole in soil and vegetables, indicating its longer persistence in the environment.

Summary: The study reveals the significant impact of increasing white light intensity on the metabolic responses of choy sum, resulting in improved nutritional quality under high light intensity but increased pest-prevention compounds under low light intensity. Pearson's correlation analysis and principal component analysis further confirmed the relationship between light intensity and metabolites, providing crucial insights for improving vegetable nutritional values in indoor farming practices.

Summary: An accurate assessment of vegetable yield is crucial for agricultural production and management. This study compared the performance of models based on intercepted photosynthetic active radiation and spectral reflectance to estimate the dry matter of Choy Sum. The results showed that the intercepted radiation-based model performed better, and the dry matter accumulation of Choy Sum was significantly affected by nitrogen rates.

Summary: Perturbations are common in metabolism, and sensitivity analysis is a key tool to understand and control their impact on metabolic networks. This paper adopts a structural approach based on network stoichiometry to investigate the network's response to perturbations in reaction rates and metabolite concentrations at equilibrium. The study focuses on the sign of the responses and identifies the subnetworks that play a major role in sign description.

Summary: The aim of this study was to analyze the glucosinolate content in Choy sum germplasm conserved at the RDA-Genebank. The study found that aliphatic glucosinolates were the most common and aromatic glucosinolates were the least common among the analyzed germplasms. Glucobrassicanapin and progoitrin were identified as highly represented glucosinolates in one of the accessions, which have therapeutic applications.

Summary: The focus of this work is sign spotting, which aims to identify whether and where a sign has been signed in a continuous, co-articulated sign language video. This is achieved by training a model using various types of available supervision, such as watching existing footage, reading associated subtitles, and looking up words in visual sign language dictionaries. The effectiveness of the approach is validated on low-shot sign spotting benchmarks. Additionally, a machine-readable British Sign Language (BSL) dictionary dataset called BslDict is provided to facilitate further study of this task.
