One of the most prominent characteristics two-dimensional quantum Hall systems are chiral edge modes. Their existence is a consequence bulk-boundary correspondence and their stability guarantees quantization transverse conductance. In this paper, we study two microscopic models, Hofstadter lattice model an extended version Haldane's Chern insulator. Both models host phases in dimensions. We tra...

Trichoadenoma is a rare skin tumor first described by Nikolowski. There are variable clinical features and tumors have been diagnosed as cysts, basal cell epithelioma and seborrheic keratosis. The microscopic feature mainly consists of numerous cysts surrounded by eosinophilic cells. Trichoadenoma is benign and treatment is by simple excision. We report a case of trichoadenoma on the nose...

the development of the dynamical core of a potential-vorticity-based atmospheric general circulation model is explored. there are some advantages of using potential vorticity (pv) as a prognostic variable in that the resulting model can give more accurate simulation of the evolution of pv, as arguably the most fundamental dynamical quantity. further, there is possibility of explicit representat...

UNLABELLED We present two siblings affected with opsismodysplasia (OPS), a rare skeletal dysplasia caused by mutations in the inositol polyphosphate phosphatase-like 1 gene. The skeletal findings include short stature with postnatal onset micromelia, marked platyspondyly, squared metacarpals, delayed skeletal ossification, metaphyseal cupping, and postnatal micromelia. Respiratory compromise, d...

the aim of this review is to focus the current knowledge about mental and behavioral disorders in usher syndrome. previous studies described the presence of various mental disorders associated with usher syndrome, suggesting possible mechanisms of association between these disorders. the most common manifestations are schizophrenia-like disorder and psychotic symptoms. mood and behavioral disor...

vaginal leiomyomas are uncommon benign tumour with variable clinical presentation. these tumours arise most commonly from anterior vaginal wall. we report a case of 50-year old postmenopausal woman who presented with urinary retention, profuse vaginal bleeding and mass protruding into vagina. local examination revealed a pedunculated mass attached to the posterior vaginal wall with vascular sta...

The classical principal chiral model in 1+1 dimensions with target space a compact Lie supergroup is investigated. It is shown how to construct a local conserved charge given an invariant tensor of the Lie superalgebra. We calculate the super-Poisson brackets of these currents and argue that they are finitely generated. We show how to derive an infinite number of local charges in involution. We...
