To achieve the efficient mechanized harvesting of fresh safflower filaments, this paper proposes a harvesting device using dual-roller gripping and pneumatic-assisted separation. According to the mechanical properties of fresh filaments, the meta-particle method is employed to co...

The Informal Care Burden of Older Adults with Disability, Dementia, and Concurrent Cardiometabolic Multimorbidity: A Qualitative Study Based on Social Ecosystem Theory

Background: The co-occurrence of disability, dementia, and cardiometabolic multimorbidity (CMM) creates a highly complex home-care context requiring informal caregivers to simultaneously provide daily living assistance, cognitive and behavioral support, and management of multiple...

STAMPformer: spectral-prior-guided multi-view attention learning for hyperspectral prediction of continuous frost damage severity in field-grown tea plants

Frost damage severely constrains the growth, development and quality formation of tea plants, underscoring the need to develop accurate field-scale methods for the assessment of frost damage severity. In this study, hyperspectral data and eight key physicochemical indicators were...

Automated deep learning-based comprehensive assessment of stent in intravascular optical coherence tomography

The process of manually identifying and quantifying coronary stents in intravascular optical coherence tomography (IVOCT) images is time-consuming and subjective. In this study, a deep learning-based target recognition model, SMA-YOLO, was developed for automatic identification a...

RCTE: A multi-class object detection framework for dental panoramic radiographs

Background Dental panoramic radiographs play an important role in oral disease screening, computer-aided diagnosis, and clinical treatment planning. However, accurate multi-class detection remains challenging due to small lesion sizes, ambiguous anatomical boundaries, insufficien...

Mechanism and parameter optimization method for ordered vibration conveying of maize ears

Ordered conveying of maize ears is critical for non-destructive handling of seed samples in plant breeding. However, the traditional response surface methodology (RSM) struggles to fit the strongly nonlinear characteristics of this process, and the underlying mechanism of ordered...

First-principles investigation of hydrogen storage in pristine AlN nanosheets with a biphenylene framework

Abstract One of the most important aspects of the energy transition towards sustainable development is the efficient storage of hydrogen, for which a diverse range of materials is being studied. Here, we investigated the structural and electronic characteristics of biphenylene al...

Integrated multi-omics analysis reveals the molecular landscape and therapeutic strategies in Chinese cervical cancer patients

Genomic or transcriptomic sequencing guides the precision of cervical cancer (CC) diagnosis; however, the molecular profile of Asian patients remains poorly understood. We established a comprehensive multi-omics cohort comprising 112 tumor-normal adjacent tissue pairs from Chines...

Does artificial intelligence impact employment in the medium-skilled labor force? Evidence from China’s National AI Innovation and Application Pilot Zones

Rapid artificial intelligence diffusion in China, shaped by government initiatives, is reshaping labor markets and raising questions about medium-skilled employment. Using a 2015–2023 panel of 287 Chinese prefecture-level cities, we examine how policy-induced artificial intellige...

In situ generation of NiFeOOH mitigates metal-organic framework degradation for ampere‑level oxygen evolution reaction and anion‑exchange membrane water electrolysis

NiFe-based metal–organic frameworks (NiFe-MOFs) require reconstruction into metal (oxy)hydroxides to achieve oxygen evolution reaction (OER) activity. However, during the OER process, deep electrochemical reconstruction can lead to the degradation and structural collapse of the o...

Harnessing Yeast Mitochondria for the Sustainable Production of High-Value Chemicals

Abstract In microbial cytoplasmic reaction compartments, competitive pathways and metabolic interactions often hinder the efficient synthesis of target compounds. In contrast, eukaryotic cells can control metabolic complexity by utilizing organelles to segregate biochemical pathw...

PFOS increases cellular uric acid content and the abundance of URAT1 and GLUT9 in HK-2 cells

Perfluorooctane sulfonate (PFOS) is a persistent environmental pollutant associated with hyperuricemia. How PFOS affects urate-related responses in human proximal-tubule cells remains incompletely understood. We examined cellular uric acid content and URAT1/GLUT9 protein abundanc...

Exogenous glycine betaine enhances drought tolerance and medicinal quality in Glycyrrhiza uralensis seedlings

Abstract Background Drought stress constrains the growth and medicinal quality of Glycyrrhiza uralensis , but the concentration-dependent physiological basis of exogenous glycine betaine (GB)-mediated stress alleviation remains incompletely understood. Methods Seedlings were grow...

Container-Number Detection and Recognition in Land-Port Yard Scenes Based on an Improved YOLO11 Detector and a Lightweight CRNN Recognizer

Automatic container-number recognition in land-port yards is challenged by clutter, illumination changes, scale variation, surface wear, and character distortion. This paper proposes a two-stage detection–cropping–recognition framework comprising an improved YOLO11 detector and a...

Fluoride Removal from Water by a La/Al Bimetallic Coordination Composite: Insights into Efficiency and Mechanisms
