an improved mit bag model with hyper central interactions is used to calculate the staticproperties of hadrons containing u, d, s and c quarks. we present a theoretical approach to the internalstructure of three-body hyper central interacting quarks in a hadron, in which we take hadron as a bag.we discuss a few of the results obtained using a six-dimension harmonic oscilator (h.o) potential, ha...

Almost hypercomplex manifolds with Hermitian and Norden metrics and more specially the corresponding quaternionic Kähler manifolds are considered. Some necessary and sufficient conditions the investigated manifolds be isotropic hyper-Kählerian and flat are found. It is proved that the quaternionic Kähler manifolds with the considered metric structure are Einstein for dimension at least 8. The c...

We compute the moduli metrics of worldvolume 0-brane solitons of D-branes and the worldvolume self-dual string solitons of the M-5-brane and examine their geometry. We find that the moduli spaces of 0-brane solitons of D-4-branes and D-8-branes are hyper-Kähler manifolds with torsion and octonionic Kähler manifolds with torsion, respectively. The moduli space of the self-dual string soliton of ...

BACKGROUND Hyper IgE syndrome (HIES) is a rare primary immune deficiency, described as Job(`)s syndrome characterized by increased serum levels of IgE, eczema, recurrent cutaneous and pulmonary infections. In this paper, we presented a case of Hyper IgE syndrome. CASE PRESENTATION A 16-year-old Iranian boy presented with a one year history of skin lesions in knees and elbows was diagnosed of ...

Dubowitz syndrome is a rare, autosomal recessive disorder characterized by intrauterine growth retardation, short stature, microcephaly, distinct facial dysmorphism, and psychomotoric retardation. The hyper-immunoglobulin E (hyper-IgE or Job syndrome) is a primary immunodeficiency characterized by recurrent staphylococcal abscesses, recurrent cyst-forming pneumonia, and an elevated serum IgE le...
