Patients with keratotic lesions distributed in a unilateral, linear, zosteriform or localized pattern and revealing histopathologic features of dyskeratotic acantholysis have been reported previously. There is some controversy in the appropriate nosologic classification of this entity. Some authors consider it as a localized form of Darier’s disease while others place it as a variant of e...

Linear lichen planus pigmentosus is considered as a combined type of linear lichen planus and lichen planus pigmentosus (LPP), and only 4 such cases have been reported in the dermatologic literature. We report one case of linear LPP that developed on the patient’s mandibular area and the right side of the extremities. The lesions on the face presented as a dark-brown streak, which was parallel ...

Abstract The optimal solutions are most sensitive to the boundary conditions when performing topology optimization of components. In many applications the design domain of the components are subjected to unilateral contact conditions. In order to obtain relevant conceptual designs by topology optimization of such systems, the contact conditions should be included explicitly in the optimization....

With isolated binocular targets, the best depth discrimination is found in the fixation plane (Blakemore, C., Journal of Physiology 211 (1970) 599). More recent studies have suggested that stereoscopic thresholds are not always a simple function of absolute disparity, but depend on the relative disparities in the stimulus. Here, we explored the effects of relative disparity in more detail, taki...

Disabling pansclerotic morphea is a rare atrophying and sclerosing disorder of the subcutaneous tissue, muscle and bone. It is characterized by atrophy of the skin, subcutaneous fat, muscle and bone involving half of the face. In some patients the atrophic lesions extend to involve the ipsilateral or contralateral upper and lower limbs with radiological evidence of hemiatrophy. The patients may...
