Numerical studies towards practical large-eddy simulation [PDF]
, 2007 Large-eddy simulation developments and validations are presented for an improved simulation of turbulent internal flows. Numerical methods are proposed according to two competing criteria: numerical qualities (precision and spectral characteristics), and

Drag reduction within radial turbine rotor passages using riblets [PDF]
, 2018 In this paper, reducing the friction losses in a radial inflow turbine rotor surface by adding engineered features (riblets) is explored. Initially, computational fluid dynamics analysis was used to study the operating mechanism of riblets and to test ...

What you see is what you step: the horizontal-vertical illusion increases toe clearance in older adults during stair ascent [PDF]
, 2015 PURPOSE Falls on stairs are a significant cause of morbidity and mortality in elderly people. A simple safety strategy to avoid tripping on stairs is increasing foot clearance. We determined whether a horizontal–vertical illusion superimposed onto stairs

Experimental and Numerical Simulation Study of Compressors with Non-Axisymmetric Layouts
Shanghai Jiaotong Daxue xuebaoThe non-axisymmetric deviation of blade stagger angle and tip clearance has significant impact on aerodynamic performance and stability in actual compressors. In this paper, three sets of compressor test, including the prototype with a uniform layout, as

Molecular Oncology, EarlyView.A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Analysis of gait kinematics to determine the effect of manipulating the appearance of stairs to improve safety: a linked series of laboratory-based, repeated measures studies [PDF]
, 2015 Background: Falls on stairs are a common and dangerous problem for older people. This series of studies evaluated whether or not selected changes to the appearance of stairs could make them safer for older people to negotiate.

Molecular Oncology, EarlyView.Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
