this study develops and analyzes preconditioned krylov subspace methods to solve linear systemsarising from discretization of the time-independent space-fractional models. first, we apply shifted grunwald formulas to obtain a stable finite difference approximation to fractional advection-diffusion equations. then, we employee two preconditioned iterative methods, namely, the preconditioned gene...

primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

in this paper, we extend and generalize some recent results on the strong laws of large numbers (slln) for pairwise independent random variables [3]. no assumption is made concerning the existence of independence among the random variables (henceforth r.v.’s). also chandra’s result on cesàro uniformly integrable r.v.’s is extended.

larsen syndrome is a skeletal dysplasia (osteochondro-dysplasia) in which multiple dislocations of the large joints are the major feature . nosology in this group of disease, which constitutes 8% of mendelian disorders in man, is primarily based on clinical and radiological features. the underlying genetic defect is 3p21.1-p14.1 in the dominant type

background: hepatitis delta virus (hdv) is a subviral human pathogen that exploits host rna editing activity to produce two essential forms of the sole viral protein, hepatitis delta antigen (hdag). editing at the amber/w site of hdv antigenomic rna leads to the production of the large form (l-hdag), which is required for rna packaging. methods: in this study, pcr-based site-directed mutagenesi...

from the beginning of emerging concept of supply chain, a variety of strategies or paradigms have been developed for supply chain organizations .the most important paradigms are four main paradigms, namely the lean, agile, resilience and green. each of these paradigms has advantages and disadvantages. using the benefits of this paradigms and the plan to eliminate the disadvantages of each parad...

schwannoma is a benign nerve sheath tumor composed of schwann cells. oral cavity is a rare site for schwannomas, tongue being the most common location. here we are presenting a case of a young adult who presented with a huge swelling in the tongue which was removed by mandibulotomy approach and pre-operative tracheostomy. a 22-year-old male patient presented to the outpatient department with a ...

lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. typically the tumor is asymptomatic unless bitten or become noticeable because of th...
