Impacts of irrigation expansion on moist-heat stress based on IRRMIP results.

Irrigation rapidly expanded during the 20 century, affecting climate via water, energy, and biogeochemical changes. Previous assessments of these effects predominantly relied on a single Earth System Model, and therefore suffered from structural model uncertainties. Here we quantify the impacts of historical irrigation expansion on climate by analysing simulation results from six Earth system models participating in the Irrigation Model Intercomparison Project (IRRMIP).

Temperature seasonality regulates organic carbon burial in lake.

Organic carbon burial (OCB) in lakes, a critical component of the global carbon cycle, surpasses that in oceans, yet its response to global warming and associated feedbacks remains poorly understood. Using a well-dated biomarker sequence from the southern Tibetan Plateau and a comprehensive analysis of Holocene total organic carbon variations in lakes across the region, here we demonstrate that lake OCB significantly declined throughout the Holocene, closely linked to changes in temperature seasonality. Process-based land surface model simulations clarified the key impact of temperature seasonality on OCB in lakes: increased seasonality in the early Holocene saw warmer summers enhancing ecosystem productivity and organic matter deposition, while cooler winters improved organic matter preservation.

ROS-responsive nanocarrier for oral delivery of monascin and enhanced alleviation of oxidative stress.

Monascin can scavenge ROS and alleviate oxidative stress but with a low fermentation rate and bioavailability. Here, we optimized the fermentation process to increase the production of monascin (508.

Solid waste management and resource recovery during the 4-crew 180-day CELSS integrated experiment.

In order to explore the management and treatment methods of solid waste in the Controlled Ecological Life Support System (CELSS) of future lunar bases, during the 4-crew 180-day integrated experiment, the Solid Waste Management and Treatment System (SWMTS) was built, in which the treatment of recyclable solid waste such as inedible plant parts and human excrement was completed through a combination of biological aerobic composting and high-temperature oxidation. Basic data on the types and amounts of solid waste generated during the 4-crew 180-day experiment mission were obtained. There were six types of solid wastes, including the work support wastes, the household support wastes, the plant cultivation wastes, the plant-based wastes, and crew feces.

Multimodal optimal matching and augmentation method for small sample gesture recognition.

In human-computer interaction, gesture recognition based on physiological signals offers advantages such as a more natural and fast interaction mode and less constrained by the environment than visual-based. Surface electromyography-based gesture recognition has significantly progressed. However, since individuals have physical differences, researchers must collect data multiple times from each user to train the deep learning model.

Collagen plays a critical role in the development of cardiovascular calcification lesions.

Synthesis of honeycomb-like citric acid-crosslinked chitosan hydrogel beads (cCHBs): Insight into structural characteristics of Cu(II)-loaded cCHBs (cCHBs-Cu(II)).

To date, it has been regarded as one of the most challenging issues to construct novel adsorbents possessing excellent adsorption performance toward heavy metals including copper ions (Cu(II)).

Revealing the enhanced role of hydroxylamine and bimetals in the CuFeO/PMS/HA system towards effective degradation of organic contaminants.

In this study, a hydroxylamine (HA)-enhanced magnetic spinel catalyst CuFeO-activated peroxymonosulfate (PMS) system (CuFeO/PMS/HA) was constructed to degrade Sulfamethoxazole (SMX). Results from experiments and theoretical calculations indicated that active species generation mechanism involved the direct activation of PMS by HA, the redox cycles acceleration on the surface of CuFeO by HA, and the synergistic action of the low valence Fe and Cu species in CuFeO for PMS activation. The efficacy of other organic pollutants removal was further validated in bio-treated landfill leachate through removal performance and toxicity assessment.

Green process for xylo-oligosaccharide production from acetic acid hydrolysis of sugarcane bagasse by an integrated membrane technology and activated carbon adsorption.

Xylooligosaccharides (XOS), consisting 2-6 xylose residues, are a new type of prebiotic and functional oligosaccharides, and can usually be produced from the xylan-riched lignocellulosic biomass by acetic acid (HAc) hydrolysis, while the waste HAc was a problem to the environment. In this study, the main aim was to recover and reuse the waste HAc in XOS production. First, it was found that a temperature of 190 °C and a hydrolysis time of 60 min were favorable for XOS production by HAc hydrolysis, and the by-products xylose and furfural were the main inhibitors, hindering the reuse of the waste HAc.

Repression of PFKFB3 sensitizes ovarian cancer to PARP inhibitors by impairing homologous recombination repair.

Background: Ovarian cancer (OC), particularly high-grade serous ovarian carcinoma (HGSOC), is the leading cause of mortality from gynecological malignancies worldwide. Despite the initial effectiveness of treatment, acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) represents a major challenge for the clinical management of HGSOC, highlighting the necessity for the development of novel therapeutic strategies. This study investigated the role of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a pivotal regulator of glycolysis, in PARPi resistance and explored its potential as a therapeutic target to overcome PARPi resistance.

Leveraging two-dimensional pre-trained vision transformers for three-dimensional model generation via masked autoencoders.

Although the Transformer architecture has established itself as the industry standard for jobs involving natural language processing, it still has few uses in computer vision. In vision, attention is used in conjunction with convolutional networks or to replace individual convolutional network elements while preserving the overall network design. Differences between the two domains, such as significant variations in the scale of visual things and the higher granularity of pixels in images compared to words in the text, make it difficult to transfer Transformer from language to vision.
