A lightweight and precision dual track 1D and 2D feature fusion convolutional network for machinery equipment fault diagnosis.

Addressing the issues of a single-feature input channel structure, scarcity of training fault data, and insufficient feature learning capabilities in noisy environments for intelligent diagnostic models of mechanical equipment, we propose a method based on a one-dimensional and two-dimensional dual-channel feature information fusion convolutional neural network (1D_2DIFCNN). By constructing a one-dimensional and two-dimensiona dual-channel feature information fusion convolutional network and introducing a Convolutional Block Attention Mechanism, we utilize Random Overlapping Sampling Technique to process raw vibration signals. The model takes as inputs both one-dimensional data and two-dimensional Continuous Wavelet Transform images.

CLEC7A Knockdown Alleviates Ischemic Stroke by Inhibiting Pyroptosis and Microglia Activation.

Background: Ischemic stroke (IS) is the leading cause of mortality worldwide. Herein, we aimed to identify novel biomarkers and explore the role of C-type lectin domain family 7 member A () in IS.

Methods: Differentially expressed genes (DEGs) were screened using the GSE106680, GSE97537, and GSE61616 datasets, and hub genes were identified through construction of protein-protein interaction networks.

Case report: Outflow reconstruction with pre-frozen allograft blood vessels during partial hepatectomy followed by tumor resection and partial liver autotransplantation for locally advanced hepatocellular carcinoma with background of cirrhosis.

surgery and autotransplantation may provide a promising option for radical resection of conventionally unresectable liver tumors. Two cirrhotic patients with hepatocellular carcinoma (HCC), which has an "awkward seat" located in the "intrahepatic vascular triangle area (IVTA)" that consists of the middle hepatic vein (MHV), the right branches of the Glisson sheath, and the inferior vena cava (IVC), underwent extended right-half hepatectomy followed by tumor resection and partial liver autotransplantation. Innovatively, the outflow of the tumor-free liver was reconstructed using pre-frozen allograft blood vessels from brain-dead donors; the patients recovered well postoperation.

Sex-specific associations between maternal exposure to metal mixtures and fetal growth trajectories: A prospective birth cohort study.

Background: The associations of prenatal metals exposure with birth outcomes have been widely assessed. However, evidence on the associations between metal mixtures and fetal intrauterine growth trajectories is scarce.

Objectives: This study aimed to explore the associations of metal mixtures with fetal intrauterine growth trajectories overall and by sex.

Generation of highly stable electron beam via the control of hydrodynamic instability.

By employing the stabilizer in the supersonic gas nozzle to produce the plasma density profile with a sharp downramp, we have experimentally demonstrated highly stable electron beam acceleration based on the shock injection mechanism in laser wakefield acceleration with the use of a compact Ti:sapphire laser. A quasi-monoenergetic electron beam with a peak energy of 315 MeV ± 12.5 MeV per shot is generated.
