BACKGROUND: Management of patients with giant hemangiomas of the liver encounters persistent controversy. Although recent case series suggest a low complication rate with nonoperative management, the classic paradigm of preventive operative resection remains. STUDY DESIGN: A retrospective cohort study was conducted of 492 patients with giant hepatic hemangioma ( 4 cm in size) diagnosed between ...

Context. Lemaître-Tolman (L-T) toy models with a central observer have been used to study the effect of large scale inhomogeneities on the SN Ia dimming. Claims that a giant void is mandatory to explain away dark energy in this framework are currently dominating. Aims. Our aim is to show that L-T models exist that reproduce a few features of the ΛCDM model, but do not contain the giant cosmic v...

In the realm of multi-axial ratcheting, a step by step mathematical approach is developed for the parameter determination of decomposed kinematic hardening rules. For this purpose, key characteristics are mathematically derived for these hardening rules under multi-axial loading. These characteristics are then utilized to develop expressions which relate the loading history to the accumulated p...

The air-injection as an active flow stabilizing techniques, were numerically examined in current work, during the aerodynamic behavior and the characteristics of an axial compressor. At first, in design condition the characteristic curve was numerically captured for a specified test compressor. The computed results showed good agreements with those obtained from the experiments, to validate the...

The aim of the current has been based on explaining the introduction of hidden and apparent factors in the context and ground of architecture, which can be influenced by it in the process of audience’s educability from a new aspect; therefore, the “data-based theory”, which is one of the newest qualitative research methods, was applied and in order to demonstrate its efficiency, Yazd Faculty of...

We study the response of the structure of an asymptotic giant branch (AGB) star to the accretion of a brown dwarf or planet in its interior. In particular, we examine the case in which the brown dwarf spirals-in, and the accreted matter is deposited at the base of the convective envelope and in the thin radiative shell surrounding the hydrogen burning shell. In our spherically symmetric simulat...

The aim of this paper is to extend the split-step idea for the solution of fractional partial differential equations. We consider the multidimensional nonlinear Schr"{o}dinger equation with the Riesz space fractional derivative and propose an efficient numerical algorithm to obtain it's approximate solutions. To this end, we first discretize the Riesz fractional derivative then apply the Crank-...
