Ageing is a significant risk factor for a wide range of human diseases. Yet, its direct relationship with ocular ageing as a marker for overall age-related diseases and mortality still needs to be explored. Non-invasive and minimally invasive methods, including biomarkers detected through ocular ima...

IntroductionAccurate segmentation of 3D medical images is crucial for clinical diagnosis and treatment planning. Traditional CNN-based methods effectively capture local features but struggle with modeling global contextual dependencies. Recently, transformer-based models have shown promise in captur...

To address the challenge of incomplete fault feature extraction in rolling bearing fault diagnosis under small-sample conditions, this paper proposes a Temporal-Graph Convolutional Fusion Network (T-GCFN). The method enhances diagnostic robustness through collaborative extraction and dynamic fusion...

In this paper, we experimentally demonstrated transmission of a 100-Gb/s discrete Fourier transform (DFT)-spread 32-quadrature amplitude modulation (QAM) discrete multitone (DMT) signal in an intensity-modulation/direct-detection system utilizing a direct-modulated laser. We find that DFT-spread can...

Purpose of reviewThe incidence of pheochromocytoma and paraganglioma (PPGL) in pregnancy is extremely low, yet it poses a significant threat to maternal and fetal safety. While studies are published annually, progress in this field remains slow. A key question is how researchers can better utilize l...

To investigate the differences in volatile flavor components of sauce-flavor (Jiangxiangxing) Baijiu in Guizhou regions with different altitude, the volatile flavor components were determined by gas chromatography (GC) and electronic nose technique. The results were systematically evaluated using pr...

In this investigation, cobalt-based composite coatings with varying concentrations of spherical tungsten boride (WB) were fabricated via laser cladding technology, specifically focusing on two compositional systems: Co + 15% WB and Co + 45% WB. The electrochemical behavior of these coatings was syst...

BackgroundTuberculous meningitis (TBM) complicated by intracranial hypertension requires aggressive neurocritical care, yet the mortality impact of sedative and antipsychotic exposure remains controversial. This study investigates the association between sedative exposure and mortality while identif...

High concentrations of divalent lead (Pb2+) in the environment induce damage to the hypothalamic–pituitary–ovarian axis (HPOA) axis, whereas 1-nitropyrene (1-NP) not only damages the brain but also leads to female reproductive toxicity. However, the effects of combined exposure to low levels of Pb2+...
