Background: Spontaneous low-frequency oscillations (LFOs) have been widely studied in cerebrovascular disease, but little is known about their role in moyamoya disease (MMD). The objective of this study was to assess the value of spontaneous LFOs in MMD based on wavelet analysis of near-infrared spectroscopy signals.
Methods: Sixty-four consecutive idiopathic adult patients were prospectively enrolled.
A size-based blood cell sorting model with a micro-fence structure is proposed in the frame of immersed boundary and lattice Boltzmann method (IB-LBM). The fluid dynamics is obtained by solving the discrete lattice Boltzmann equation, and the cells motion and deformation are handled by the immersed boundary method. A micro-fence consists of two parallel slope post rows which are adopted to separate red blood cells (RBCs) from white blood cells (WBCs), in which the cells to be separated are transported one after another by the flow into the passageway between the two post rows.

Article Synopsis
- Breast cancer is a common and serious illness among women, and early detection is crucial for saving lives; therefore, a safe and effective detection method is essential.
- Researchers are focusing on a new detection system using a 780 nm laser to analyze breast tissue, which involves computer-controlled two-dimensional scanning and the use of a photomultiplier tube (PMT) to convert light into an electrical signal for image processing.
- In clinical trials involving 50 patients, the near-infrared (NIR) imaging showed a 72.5% accuracy rate in detecting breast diseases, comparatively placing it between ultrasound and mammography accuracy, while also identifying distinct characteristics of various breast conditions through NIR images.
