Utilizing semiconductor nanowires for (opto)electronics requires exact knowledge of their current-voltage properties. We report accurate on-top imaging and I-V characterization of individual as-grown nanowires, using a subnanometer resolution scanning tunneling microscope with no need for additional microscopy tools, thus allowing versatile application. We form Ohmic contacts to InP and InAs nanowires without any sample processing, followed by quantitative measurements of diameter dependent I-V properties with a very small spread in measured values compared to standard techniques.

Who was actually the director of the Department of Neurology and Psychiatry at Balassa Street, for a long time also referred to as the Moravcsik Clinic? A polymath, a genius, or rather a knight of fortune who wanted to draw attention to himself by building a clinic for himself? We looked into this on the occasion of his death anniversary. How did he get from the head of the department to the founding of the Psychiatry and Neurology Clinic? He dreamed up every corner of the Department, which was the most impressive and patient-friendly clinic of its time even in European terms. The building was not only used for the recovery of patients, but also for the continuous medical training of doctors.

Dementia and the associated stigma pose unique threats to the identity of persons with dementia, triggering attempts to cope with resulting identity changes. We explore identity change narratives and metaphors written by people with dementia and care partners in public blog posts. These metaphors reflect bloggers' motivation to adapt, adjust, and cope with identity change and their motives to challenge common misunderstandings of dementia as a complete loss of selfhood.

Autoimmune enteropathy (AIE) is a rare immune mediated disorder primarily affecting children, characterized by chronic diarrhea, malabsorption, vomiting, weight loss and villous atrophy. It has also been observed in adults presenting diagnostic and treatment challenges due to its overlap with other gastrointestinal disorders such as celiac disease. Initial diagnostic criteria for AIE include small bowel villous atrophy, lack of response to dietary restrictions, presence of anti-enterocyte antibodies, and predisposition to autoimmunity without severe immunodeficiency.

Sleep Adv

Department of Psychiatry, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.
Study Objectives: Sleep spindles, defining electroencephalographic oscillations of nonrapid eye movement (NREM) stage 2 sleep (N2), mediate sleep-dependent memory consolidation (SDMC). Spindles are also thought to protect sleep continuity by suppressing thalamocortical sensory relay. Schizophrenia is characterized by spindle deficits and a correlated reduction of SDMC.
