Active wake control of a rectangular cylinder near a free surface via mode-aware deep reinforcement learning

This study investigates active wake control of a rectangular cylinder near a free surface using a mode-aware deep reinforcement learning (DRL) framework aimed at reducing drag and suppressing vortex shedding. The flow is modeled as a two-dimensional incompressible two-phase syste...

Experimental study on the axial compression mechanical performance of thin-walled square steel tube-glued laminated timber composite hollow columns

To further enhance the compressive performance of glued laminated timber columns, thin-walled square steel tubes were bonded with glued laminated timber on the outer side to form thin-walled square steel tube-glued laminated timber composite hollow columns. Taking the hollowness...

Nanopore Sequencing for Epigenetic Decoding: Applications, Analytical Constraints, and Translational Prospects

Epigenetic regulation involves multiple molecular layers, including DNA and RNA modifications, histone post-translational modifications (PTMs), and chromatin accessibility. These processes contribute to cell identity, development, and disease, but their measurement remains techni...

Comparison of One-Dimensional and Quasi-Two-Dimensional Friction Models for Hydraulic Transient Response and Energy Dissipation in Viscoelastic Pipelines at Different Water Temperatures

Abstract In chemical process systems, high-density polyethylene (HDPE) piping is widely used for conveying thermally conditioned liquids because of its corrosion resistance and operational flexibility; however, its pronounced viscoelastic response during hydraulic transients can...

Lanthanide phosphors doped stimuli‐responsive fibres for advanced information encryption and anti‐counterfeiting: In both dark and bright situation

Abstract The increasing prevalence of flexible wearables underscores the urgent need for advanced anti‐counterfeiting technologies. However, photoluminescent anti‐counterfeiting fibre materials are currently plagued by inherent environmental light dependency flaws. Their fluoresc...

Sustainable solar water purification: Exploring the structural advantages of higher plants

Solar vapor generation is a promising technique for water purification, although the development of efficient and sustainable systems for practical use remains challenging. Here, we introduce a higher plant–derived evaporator, leveraging the structural advantages of plants and th...

Indirect Adventitious Shoot Organogenesis and Plant Regeneration from Solanum nigrum L.

Solanum nigrum L. plays an important role in anti-tumor activity. Previous studies have reported an imperfect in vitro regeneration system with unclear regeneration processes. This study firstly screened the optimal explant type for regeneration, and leaf explants were finally se...

Methane bursts during spring thaw in the permafrost region of Northeast China

Spring thaw in permafrost regions is associated with episodic bursts in atmospheric methane concentration. In this study, these methane bursts were investigated across different permafrost types in Northeast China. MODIS data and Sentinel-5P methane observations were used to deri...

Contrasting climatic controls on bimodal growth of Pinus elliottii plantations between northern and southern subtropical zones

Subtropical plantation forests play a crucial role in the global carbon cycle, yet intensifying global warming may exert profound impact on tree growth and forest carbon uptake. Pinus elliottii Engelm. is a widely planted and representative plantation species in subtropical regio...

Tuning the long-range corrected functional for accurate excited-state spectroscopic, charge transport, and interfacial insights into D-π-D type hole transport materials

The development of small molecule hole transport materials (HTMs) with high flatness through reasonable molecular design to regulate the interfacial interaction and charge transport of perovskite solar cells (PSCs) has become a current research hotspot. This study used the high-p...

Identification and Functional Characterization of UbiA-Type Terpene Synthases in Inonotus obliquus

Abstract Inonotus obliquus (Chaga mushroom) is a medicinal basidiomycete rich in structurally diverse terpenoids, yet the biosynthetic enzymes responsible for sesquiterpene formation remain poorly understood. Here, we identified six UbiA-type terpene synthases (IoUbiA1-6) from th...

Decision-making and planning for autonomous vehicles on foggy highway obstacle sections under visual perception

To enhance the safety and decision reliability of automated driving vehicles on foggy highway obstacle sections, this study addresses three key challenges: visual perception degradation, increased uncertainty in obstacle localization, and trajectory instability under high-speed c...

Ce/Mn-MOF with Multiple Enzyme-Mimetic Activities Enables the Alleviation of Plant Saline-Alkali Stress

Abstract Saline-alkali stress impairs plant growth via ROS overaccumulation, while MOF nanozymes offer a promising redox-regulation strategy. In this study, a Ce/Mn-MOF nanozyme was synthesized via a solvothermal method through a bimetallic doping strategy. The reversible valence...
