CP violation in the Standard Model (SM) [1] is described by an irreducible complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing 3 × 3 matrix [2]. The equation VudV ⋆ ub + VcdV ⋆ cb + VtdV ⋆ tb = 0, which follows from the unitarity of the CKM matrix V , can be depicted as a triangle – called the Unitarity Triangle (UT) – in the complex plane [3]. The main goal of the B-factories is ...

In the present study, artificial neural networks (ANNs) technique was implemented to link non-dimensional pressure coefficients and flow characteristics calibrate a five-hole probe. The experimental data of this work were obtained from subsonic open-circuit wind tunnel at velocity 10 m/s. Here, efficiency ANNs compared with two conventional reduction methods, including linear interpolation 5th-...

BACKGROUND Percutaneous lag screw fixation is an alternative treatment for non-displaced or minimally displaced posterior column fractures. This study aims to explore new fluoroscopic views of the acetabulum for safe percutaneous insertion of posterior column lag screws. METHODS Axial computed tomography (CT) scans were taken of sixteen embalmed adult cadavers. The axial CT images at the leve...

The conformational properties of Ac-∆(Me)Ala-NHMe (N-acetyl-N-methyl-α,β-dehydroalanine N’methylamide), as the simplest model of N-methyl-α,β-dehydroamino acids, was examined with theoretical methods and in comparison with Ac-∆Ala-NHMe and Ac-∆Ala-NMe2. The N-terminal amide of the ∆(Me)Ala residue easily adopts the configuration cis and the torsion angles φ, ψ are highly flexible. The ∆(Me)Ala ...
