Integrated proteomics and glycoproteomics reveal metabolic reprogramming in Nannochloropsis oceanica under CO₂ limitation

Nannochloropsis oceanica , a model oleaginous microalga with emerging applications in food and bioenergy, relies on carbon-concentrating mechanisms (CCMs) to adapt to low CO₂ conditions, yet the role of glycosylation in this process remains unclear. Here, we applied 4D-DIA proteo...

Agricultural Industry Agglomeration and Carbon Emission Intensity: A Systems Perspective on Resilience and Digital Development

Decarbonizing agriculture depends not only on the efficiency of individual production activities but also on coordination among production, processing, and service activities. From a systems perspective, this study treats provincial agriculture as an interconnected industrial sys...

Wear and Corrosion Properties of Laser-Cladding Ti-Hf-Mo-Ta-Nb-B Coating on Ti60 Titanium Alloy

Ti60 is a type of high-temperature titanium alloy that not only withstands high temperatures during long-term service, but also has excellent wear resistance and corrosion resistance. To enhance the wear and corrosion resistance of a Ti60 substrate, a Ti-Hf-Mo-Ta-Nb-B coating was...

Deep Eutectic Solvents Featuring Dual Amino Sites for Efficient and Reversible CO2 Capture with Molecular-Level Insights

Abstract In this study, a series of nonaqueous deep eutectic solvents (DESs) with dual amino sites were facilely constructed, among which the optimal DES (AEtMImBr: MEA (1:5)) achieved a CO2 capture capacity of 0.204 g/g at 333.15 K and 1 bar. Moreover, this DES maintained stable...

A dual-tower multimodal framework with feature quality enhancement for predicting pathological complete response after neoadjuvant chemotherapy in breast cancer: a multicenter study

BACKGROUND: Pathological complete response (pCR) is a key endpoint following neoadjuvant chemotherapy (NAC) in breast cancer, with potential to guide treatment adaptation and surgical de-escalation. However, limited generalizability across institutions remains a major challenge d...

Cross-Rotor Coassembly of AIEgens for Dual-NIR-II Laser-Enhanced Imaging-Guided Phototheranostics

Abstract Phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), offers a minimally invasive approach with precise spatiotemporal control for cancer treatment. However, conventional photosensitizers are prone to aggregation-caused quenching, which lower...

The Effects of Mindfulness-Based Interventions on Proprioception: A Bayesian Multilevel Meta-Analysis of Evidence from Randomized Controlled Trials

Proprioception is crucial for physical activities, motor control, balance, and coordination, yet strategies to enhance it remain debated. Mindfulness-based interventions (MBIs) may improve proprioception by enhancing body awareness through attention regulation and body-mind syner...

Potential Land-Use Functional Conflict Maps and Near-Term Built-Up Expansion: A Prospective Assessment on Hainan Island, China

Suitability-overlap maps of potential functional conflict are widely used to identify potential land-use trade-offs, yet their ability to identify subsequent conversion is rarely tested. We examined whether potential functional conflict (C), measured by suitability overlap, adds...

Quantum correlations of tripartite mixed states in the black hole quantum atmosphere

Abstract We investigate quantum state texture, genuine multipartite entanglement, and tripartite nonlocality of a tripartite mixed state in the black hole quantum atmosphere. By introducing the Hartle-Hawking local temperature into the Bogoliubov coefficients, we characterize the...

Geometric quantum discord in the black hole quantum atmosphere

Abstract We investigate the geometric quantum discord of bipartite Werner states influenced by Hawking radiation in the quantum atmosphere of a Schwarzschild black hole. We find that the geometric quantum discord in the physically accessible region exhibits non-monotonic behavior...

Formation control for multiple similar autonomous underwater vehicles with dynamic gaps via deep reinforcement learning

Dynamic gaps between simulation and real world environments are the major challenge for the implementation of deep reinforcement learning (RL) based formation control methods in systems composed of multiple similar autonomous underwater vehicles (AUVs), mainly involving hydrodyna...

Stress Mindset and Psychological Distress in Primary and Secondary School Teachers: The Serial Mediating Role of Future Control and Burnout

Background/Objectives: As China prioritizes a high-quality teacher workforce, teachers’ mental health has gained growing attention. The stress-is-enhancing mindset has been linked to adaptive psychological functioning, but evidence among teachers remains limited. Drawing on conse...

Transcutaneous Auricular Vagus Nerve Stimulation Selectively Improves Executive Control and Cognitive Flexibility Following Sustained High Cognitive Load: A Randomized, Single-Blind, Sham-Controlled Study

Objectives: Acute exposure to sustained high cognitive load rapidly depletes executive functions, yet rapid, field-compatible countermeasures remain scarce. This study examined whether transcutaneous auricular vagus nerve stimulation (taVNS) improves cognitive functions across mu...

Ecology and Brain Size Drive Feeding Innovations in Birds

Feeding innovations, reflecting behavioral plasticity, are crucial for animals adapting to rapidly changing environments. Although larger brains are theorized to enhance adaptability by increasing behavioral flexibility, the combined influences of brain size and ecological factor...

Peer Victimization and Non-Suicidal Self-Injury Among Chinese Adolescents: Moderating Roles of Teacher Emotional Support and Parent–Child Cohesion

Non-suicidal self-injury (NSSI) is a highly prevalent maladaptive psychological behavior among adolescents and a significant public health concern. Drawing upon ecological systems theory, this cross-sectional study of 4128 adolescents (M = 12.78, SD = 0.96; 51.6% male) aimed to i...

Integrated lipidomics and gut microbiome analyses to understand metabolic adaptation during hibernation in Pelodiscus sinensis

Hibernation is the most critical and vulnerable stage in the life cycle of animals, during which organisms must maintain energy homeostasis and undergo metabolic regulation under prolonged low temperatures and fasting conditions. Turtles, as ancient ectothermic vertebrates and on...

A colour image encryption method based on a coupled map lattice–elementary cellular automaton neurodynamic chaotic system and dynamic dual-affine substitution-box architecture

Abstract Secure colour image transmission requires encryption schemes in which randomness generation, nonlinear substitution and diffusion are designed as a coherent whole. Conventional coupled map lattice-based methods are often constrained by fixed neighbourhood evolution and l...

Reactive Iron-Bound Organic Carbon Shows Unexpected Persistence under Anoxic Burial

Abstract The interaction between organic carbon (OC) and reactive iron (FeR) plays a critical role in suppressing OC mineralization, with the resulting FeR-bound OC (FeR-OC) constituting an important carbon sink in marine sediments. Traditional views suggest that under anoxic con...
