The high redshift observations of galaxies now becoming available from the Hubble Space Telescope and from large ground based telescopes are opening fresh windows on galaxy formation. Semianalytic models of galaxy formation provide us with a powerful tool to interpret and understand these exciting new data. In this review, we explain the philosophy behind this class of model and outline some of...

The number of infrared beamlines at synchrotron facilities is expending worldwide. Due to the long wavelength of the radiation in the infrared region, the optimum collection of the emitted photons requires large opening angles, both vertically and horizontally (order of few tens of mrad). Most of the infrared beamlines use toroid shaped mirrors, or elliptical mirror to conjointly focus both the...

In this paper, we further develop the theory of complete mixability and joint mixability, we provided sufficient conditions for certain univariate distributions with oneside unbounded support that are not joint mixable and complete mixable. An alternative proof to a result of Wang and Wang (2016) which related to the joint mixability of elliptical distributions with the same characteristic gene...

A computational fluid dynamic (CFD) study compared two configurations of distal anastomosis of 12 mm Contegra conduit: conventional 'circular' vs. oblique 'elliptical' anastomosis extended on the left PA, evaluating pressure and velocity profiles, and shear stress, from PA origin to the bifurcation. 'Elliptical' anastomosis provides larger (=54% difference) cross-sectional area than 'circular' ...

A novel flexure hinge named half circular-elliptical hybrid flexure hinge was presented. Based on Castigliano’s Displacement Theorem, the compliance equations of the novel flexure hinge were formulated. A computer aided analysis and parametric design program of the half circular-elliptical hybrid flexure hinge was developed by VC++6.0. A specific half circular-elliptical hybrid flexure hinge wa...

We examined the voltage-dependent block of Ca(2+)-activated Cl(-) channels by anthacene-9-carboxylic acid (A9C), diphenylamine-2-carboxylic acid (DPC), 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS), and niflumic acid (NFA) in excised inside-out and outside-out patches from Xenopus oocytes. The fraction of the voltage field (delta) experienced by the blocking drug was determined from t...

30 ‘circular’ vs. oblique ‘elliptical’ anastomosis extended on the left PA, evaluating pressure and velocity profiles, and shear stress, from PA 31 origin to the bifurcation. ‘Elliptical’ anastomosis provides larger (s54% difference) cross-sectional area than ‘circular’ anastomosis. Velocity 32 contours showed important stagnation at PA bifurcation in ‘circular’ anastomosis and minimal in ‘elli...

In this paper, we derive the second-order crack opening displacement tensor for an arbitrarily oriented elliptical in elliptically orthotropic (EO) matrix. This result is obtained explicit closed form. The approach based on Saint-Venant’s idea of linear transformation between boundary value problems and isotropic bodies. solution utilizes classical representation ellipsoid where smallest aspect...

Using complex variable methods and conformal mapping techniques, we establish the existence of coated cavities of various shapes that do not disturb the warping function in a host elliptical bar. These cavities are known as ‘partly neutral cavities’. Our results show that the two axes corresponding to the neutral elliptical coating are parallel to those of the host elliptical bar and that the c...
