Electromagnetic response of metamaterials is not only determined by its component materials but also the microstructure and arrangements of its resonant elements.The perfect absorber prepared by metamaterial (PMA) can realize 100% absorption in specific frequency bands by designing reasonable structures of resonators.PMA can be applied in many doma
We have reconstructed a new, homogeneous geomagnetic Dst index for 1932-2002, thus extending the original Dst index by 25 years, i.e.by more than one full solar magnetic cycle.The extension was done by using data from the original set of four low-latitude stations for 1941-1956, and by using the nearby CTO station as a predecessor of the HER statio
Authors report the case of a 51-year-old man, presenting with epigastralgia of recent onset.Physical exam was unremarkable.Endoscopy revealed a large, ulcerated, submucosal, antral tumor.CT scan reveals an antral mass with fat attenuation.The MINT SOAP patient underwent a total gastrectomy.Macroscopic examination identified in the antral wall a 9-c
Abstract Background Named Entity Recognition (NER) is a long-standing fundamental problem in various research fields of Natural Language Processing (NLP) and has been practiced in many application scenarios.However, the application results of NER methods in Chinese electronic medical records (EMRs) are not satisfactory, mainly due to the following
This article addresses the challenges of renewing the professional training of historians in a global context increasingly characterized by the ubiquity of information technologies in all dimensions of social life.We Pill Boxes analyze our recent pedagogic experiences, strongly inspired in the theoretical-methodological reflections by US historian
