Summary: This paper proposes a new edge detection network composed of modulation coding network and decoding network. The modulation enhancement network improves the feature extraction ability, while the decoding network combines top-down and bottom-up decoding to achieve better performance by fusing decoding features. Experimental results show that this method is highly competitive on multiple datasets.

Summary: Radical philicity, the ability of radicals to act as nucleophiles or electrophiles, is an important concept in organic chemistry. Traditionally, radicals are considered electron deficient, but the term "electron deficient" can imply electrophilicity in modern literature. This discrepancy has led to misconceptions about radical behavior, as many radicals actually exhibit nucleophilic behavior. This review aims to guide the understanding and prediction of radical philicity, demonstrating that not all radicals behave as electrophiles.

Summary: The study compared the effects of different enzymes on the solubilization and recovery of components from microalgae-bacteria grown in piggery wastewater and microalgae grown in synthetic media by enzymatic hydrolysis. Results showed higher carbohydrate solubilizations from microalgae-bacteria compared to pure microalgae, and Proteases solubilized xylose remarkably well. Alcalase hydrolysis provided the highest peptide recovery, while Protamex resulted in low peptide recoveries but larger peptide sizes.

Summary: The polycondensation of glycerol and aliphatic dicarboxylic acids catalyzed by Candida antarctica lipase B results in branched polyesters with diverse amphiphilicity and physical properties. The molar mass and properties of the polyesters are influenced by the choice of diacids and the reaction conditions. These glyceride-like polyesters can be used to produce nanoparticles with specific hydrodynamic properties.

Summary: This paper proposes an effective process of radical concept generation, which involves identifying radical technology opportunities, determining the search direction of cross-domain knowledge, selecting appropriate cross-domain knowledge, and forming radical concepts using the cross-domain knowledge as inspirations. This method can reduce risks and costs caused by uncertainty and has the potential to foster research on radical innovation and knowledge-based innovation.

Summary: The physiological and biochemical effects of high salinity on young cork oak plants include changes in pigment levels, increased sugars, impaired PSII photochemistry, oxidative damage, and alterations in enzyme activities. These observations highlight the adaptations of cork oak to high salinity, but also suggest the need for further studies to understand its response to diverse salinity conditions. The data generated provide valuable information for conservation and management programs in salt-affected areas in the Mediterranean region, as well as the selection of salt-tolerant species.

Summary: The study elucidated the mechanisms involved in the hydrothermal conversion of lamellar silicates into zeolites, showing that MOR phase formation follows a classical reconstructive pathway while Na-P1 and ZSM-34 structures result from a nonclassical recrystallization process. Understanding these synthetic mechanisms is crucial for the intelligent design of new and useful materials.

Summary: This paper proposes a new selective quantum ensemble learning model (SELA) based on improved AdaBoost and local sample information. SELA combines information entropy and random subspace to preserve important features of the classification task. It selects a base classifier that balances accuracy and diversity among a group of base classifiers generated based on local AdaBoost. The quantum genetic algorithm is used to search optimal weights for base learners in the label prediction process.

Summary: The modern era of agriculture focuses on the impact of the environment on crop growth and development, and shading is a crucial factor that has been neglected. This study investigated the effects of shading at flowering and pod development stages on rapeseed nutrition, carbohydrates, and yield. The results showed that shading disturbed nitrogen accumulation and transportation, and led to reduced dry matter and yield. The study also revealed the critical growth stage affected by shading. In addition, the study highlighted the different responses of rapeseed genotypes to shading stress.

Summary: C-glycosides are important natural products and potential medicinal candidates. Nickel-catalyzed C-glycosylation reactions provide a promising strategy for their synthesis. Achieving stereoselective synthesis of alpha- and beta-C-glycosides has been a challenge, but recent developments in nickel-mediated strategies have addressed this problem. This review summarizes the advancements in diastereoselective C-glycosylation reactions and discusses the mechanistic understandings of these methods.
