Traditional online learning algorithms often suffer from the lack of convergence rate and accuracy. The Dyna-2 framework , combining learning with searching methods, provides a way of alleviating the problem. The main idea behind it is to execute a simulation-based search that helps the learning process to select better actions. The search process relies on(More)
BACKGROUND Caveolin-1 is a key structural and functional protein. Caveolin-1 is known to modulate multiple signal-transducing pathways involved in cell differentiation and proliferation. Psoriasis is viewed as a multifactorial pathology characterized by keratinocyte hyperproliferation and abnormal cell maturation. OBJECTIVES To examine the expression of(More)

To investigate the value of the guidance of three dimensional (3-D) reconstruction of multi-slice spiral CT (MSCT) for the placement of pedicle screws, the 3-D anatomical data of the thoracic pedicles were measured by MSCT in two embalmed human cadaveric thoracic pedicles spines (T1-T10) to guide the insertion of pedicle screws. After pulling the screws(More)
