Transfer Learning for Automatic Sleep Staging Using a Pre-Gelled Electrode Grid.

Novel sensor solutions for sleep monitoring at home could alleviate bottlenecks in sleep medical care as well as enable selective or continuous observation over long periods of time and contribute to new insights in sleep medicine and beyond. Since especially in the latter case the sensor data differ strongly in signal, number and extent of sensors from the classical polysomnography (PSG) sensor technology, an automatic evaluation is essential for the application. However, the training of an automatic algorithm is complicated by the fact that the development phase of the new sensor technology, extensive comparative measurements with standardized reference systems, is often not possible and therefore only small datasets are available.

Measuring the Economic Impacts of a Circular Economy: an Evaluation of Indicators.

Unlabelled: A circular economy (CE) is often seen as a promising way to address pressing environmental challenges, such as climate change, biodiversity loss, and resource depletion. However, the CE concept remains contested, and the implementation of circular strategies (CS) does not automatically improve all dimensions of sustainability. However, assessing the economic impacts of CS implementation is crucial to making the transition from linear to circular value chains.

Benign skin lesions: lipomas, epidermal inclusion cysts, muscle and nerve biopsies.

Lipomas are benign skin tumors composed of mature fat cells and are the most common subcutaneous tumors. Although many of these can be removed in the surgical clinic or minor operating room, some require more advanced preoperative planning and more complicated resection. The diagnosis, pathology, and treatment of benign tumors, and other commonly associated tumors that may require a more substantial workup and operative intervention, are discussed.

Management of major hepatic trauma involving interhospital transfer.

A recent 10-year experience with major liver trauma at the Maine Medical Center was reviewed in order to examine treatment options involving interhospital transfer in the management of major liver trauma in rural areas. Liver injuries of at least Grade III by the systems of Moore or Mirvis were included, except for patients admitted without vital signs. We found 98 cases of major hepatic trauma, of which 54 had been referred by 21 smaller hospitals.
