A data-driven wall model for turbulent flows over periodic hills is developed using a feedforward neural network and wall-resolved large-eddy simulation data. The employs wall-normal distance, near-wall velocities, pressure gradients as input features, the shear stresses output labels, respectively.

Background & Aims: Tuberculosis is one of the most important causes of mortality in the world and if it is not treated, 50 – 65% of patients would die in five years. Chest X-ray has an important role in the diagnosis of TB and early diagnosis and treatment prevent tuberculosis transmission. In this study we evaluated radiologic manifestations of patients with smear positive pulmonary tubercu...

introduction: poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. scattered photons are the main cause of degrading the contrast and resolution in spect imaging that result in error in quantification. thallium decay is very complicated and photons ar...

Optical pump-probe setups are commonly used for excitation and investigation of the spin dynamics in various types magnetic materials.
