The main problem with localized discriminant techniques is the curse of dimensionality, which seems to restrict their use to the case of few variables. This restriction does not hold if localization is combined with a reduction of dimension. In particular it is shown that localization yields powerful classifiers even in higher dimensions if localization is combined with locally adaptive selecti...

A patient aged 58 years, diabetic, consulted for the appearance of a lesion on the left thigh that evolved for 2 years. The clinical examination found a plaque, with digital edges, hyper-pigmented center dotted with a few areas of skin atrophy and a hypochromic periphery. The lesion was not infiltrated, mildly pruriginous and measured 10 cm of major axis (Panel A). There were no adenopathies. H...

A 28-year-old male patient presented to us with the history of swelling over the left foot, the proximal left leg, and another separate swelling over the left greater trochanteric region since birth. The rate of enlargement of digits was disproportionate to age. For the last 2 years, he started complaining of decreased sensation over the dorsum of the left foot and sole. The physical examinatio...

We study products of precursors of spatially local operators, Wxn(tn) . . .Wx1(t1), where Wx(t) = e Wxe iHt. Using chaotic spin-chain numerics and gauge/gravity duality, we show that a single precursor fills a spatial region that grows linearly in t. In a lattice system, products of such operators can be represented using tensor networks. In gauge/gravity duality, they are related to Einstein-R...

We introduce and analyze LocBoost, a new boosting algorithm, which leads to the incremental construction of a mixture of experts type architecture. We provide upper bounds on the expected loss of such models in terms of the smoothness properties of the gating functions appearing in the mixture of experts model. Furthermore, an incremental algorithm is proposed for the construction of the classi...

This study represents an unusual case of mucormycosis localized in nasal cavity of a German shepherd dog. The patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. The dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. Initial nasal rhinoscopy showed s...

Granuloma annulare(GA) is an inflammatory benign cutaneous disease of unknown etiology that may manifest different clinical features. The most common presentation or classic form of the disease is manifested as flesh colored, annular grouped papules, commonly involving the hands and feet. Various skin injuries and infections have been reported to trigger GA, including insect bites, warts,...

Leishmaniasis include several clinical manifestations, mostly cutaneous, visceral and mucosal (1, 2). Various species can lead to diverse clinical presentations. Thus species identification contribute to proper management (3). Localized Leishmania Lymphadenitis (LLL) is a distinct entity in clinicopathologic field presenting with isolated lymphadenitis and possible cocomitant cutaneous...
