Haematurias present serious problems in differential diagnostics. Although no clear-cut instructions exist, patients with haematuria are usually directed to urological surgeries or inpatient departments. Here they are routinely checked by a number of invasive techniques (cystoscopy, i. v. urography, aortography etc.) before the urological nature of(More)
A 51-year-old female developed linear-like scleroderma in the left thigh following a linear wound caused by a car accident. 27 years later she also developed a typical diffuse cutaneous systemic sclerosis with extensive skin involvement and bibasilar pulmonary fibrosis. The second case is a 39-year-old female who had a history of Raynaud's phenomenon since(More)
Artificial graphene consisting of honeycomb lattices other than the atomic layer of carbon has been shown to exhibit electronic properties similar to real graphene. Here, we reverse the argument to show that transport properties of real graphene can be captured by simulations using "theoretical artificial graphene." To prove this, we first derive a simple(More)
Snake states are trajectories of charge carriers curving back and forth along an interface. There are two types of snake states, formed by either inverting the magnetic field direction or the charge carrier type at an interface. The former has been demonstrated in GaAs-AlGaAs heterostructures, whereas the latter has become conceivable only with the advance(More)
Necrotizing histiocytic lymphadenopathy (NHL) is a rarely observed clinical entity that is occasionally associated with systemic lupus erythematosus (SLE). The histological features of the condition have been considered to be indistinguishable from those of lymphadenitis in subjects with SLE, and the clinical symptoms of the two disorders share common(More)
Watermelon-stomach is a rare cause of gastrointestinal bleeding. There has been an increasing number of reports on the association of this lesion with diseases of the scleroderma group, causing chronic, sometimes severe gastrointestinal blood loss. The present report presents the case of a 75-year-old female with limited cutaneous systemic sclerosis and(More)
The formation of quantum Hall channels inside the bulk of graphene is studied using various contact and gate geometries. p-n junctions are created along the longitudinal direction of samples, and enhanced conductance is observed in the case of bipolar doping due to the new conducting channels formed in the bulk, whose position, propagating direction and, in(More)
