Large Receptive Field Networks for High-Scale Image Super-Resolution

Convolutional Neural Networks have been the backbone of recent rapid progress in Single-Image Super-Resolution. However, existing networks are very deep with many network parameters, thus having a large memory footprint and being challenging to train. We propose Large Receptive Field Networks which strive to directly expand the receptive field of Super-Resolution networks without increasing depth or parameter count. In particular, we use two different methods to expand the network receptive field: 1-D separable kernels and atrous convolutions. We conduct considerable experiments to study the performance of various arrangement schemes of the 1-D separable kernels and atrous convolution in terms of accuracy (PSNR / SSIM), parameter count, and speed, while focusing on the more challenging high upscaling factors. Extensive benchmark evaluations demonstrate the effectiveness of our approach.Comment: Accepted as a conference paper at CVPR2018 in the NTIRE Workshop http://www.vision.ee.ethz.ch/en/ntire18

The earliest mention of a black bag.

A black bag, needed especially for home visits, has been used since the time of Hippocrates who, in his treatise "On good manners", gave the first detailed description of a medical bag with guidelines for the required equipment and structure. Ancient Egyptian and Palestinian references also date back at least two millenniums

Alexandre Yersin's explorations (1892-1894) in French Indochina before the discovery of the plague bacillus.

Alexandre Yersin, the great French discoverer of yersinia pestis, was a keen explorer of unknown lands. At the age of 30, a member of the French Colonial Health service, he set off to fulfil his intimate dream and explore other continents. For almost two years and three long expeditions, he journeyed through widely unknown regions in the province of the French Indochina, in southeast Asia, territories of Vietnam, Cambodia and Laos. This article presents vignettes from his explorations. During his difficult travels, he carefully planned and noted his itineraries; designed new routes, but also observed and recorded sociodemographic and environmental data and unidentified diseases. The immature science of late 19th century geography had the strength to allure such an influential medical figure and place him among the early medical geographers. His journeys, observations and recordings brought to Yersin great experience, and he made his most important scientific contributions after he had concluded his explorations

UTJECAJ STAROGRČKE MEDICINE U INDIJI: ROĐENJE UNANI MEDICINE

Background: Unani Medicine, also called “Unani-tibb”, has a long and impressive record in India based on the grecoarabic medicine and teachings of Hippocrates, Galen and Arab physicians. Its main principle is the maintenance of equilibrium among the various aspects of the body, made up of four elements, different temperaments, simple and compound organs, and four humours. Methods: The main bibliographic sources concerning the impact of ancient Greek medicine in India and the principles of Unani Medicine have been investigated and analysed. Results: The assimilation of Hippocratic principles in a country with a different philosophy and worldview was successful. The ancient Greek medical system enriched with local elements encountered a large response to the Indian people and to the physicians. Conclusions: Nowadays Unani medicine is not only popular in India where several Unani practitioners are registered but it enjoys a worldwide upsurge of interest.Pozadina: Unani medicina, također poznata pod nazivom „Unani-tibb“, ima dugu i impresivnu povijest u Indiji koja se temelji na grčko-arapskoj medicini i učenju Hipokrata, Galena i arapskih liječnika. Njen glavni princip je održavanje ravnoteže među različitim aspektima tijela, sastavljenome od četiri elementa, različitih temperamenata, jednostavnih i složenih organa te četiri tekućine. Metode: Istraženi su i analizirani glavni bibliografski izvori koji se odnose na utjecaj antičke grčke medicine u Indiji i na načela Unani medicine. Rezultati: asimilacija Hipokratovih načela u zemlji s različitom filozofijom i pogledom na svijet bila je uspješna. Drevni grčki medicinski sustav obogaćen s lokalnim elementima naišao je na veliki odaziv indijskog naroda i liječnika. Zaključak: Danas Unani medicina nije samo popularna u Indiji, gdje je registrirano nekoliko praktičara Unani medicine, već ona uživa porast interesa u cijelom svijetu

Giht u djelima znamenitih grčkih i bizantskih liječnika

Gout is a medical condition with typical recurrent attacks of acute inflammatory arthritis. The severity of this illness has been recognised from antiquity, and several ancient physicians studied it intensively. This paper presents the pathogenesis of the disease, approaches to therapy and preventive measures based on a number of original medical scripts from Hippocrates to the end of the Byzantine era.Giht je stanje koje se obično opisuje rekurentnim napadima akutnog upalnog artritisa. Težina ove bolesti uočena je još u antici kada te ju je proučavalo više starih liječnika. U našemu radu predstavljamo patogenezu bolesti, terapijski pristup i preventivne mjere temeljene na brojnim liječničkim zapisima, od Hipokratova vremena do završetka bizantskoga razdoblja

The “torpedo” effect in medicine

The natural electrical phenomena fascinated humans since antiquity. The electrical discharges produced by the torpedo fish were highly appreciated among ancient physicians as Hippocrates, Scribonius Largus and Galen and were prescribed for headache, gout and prolapsed anus. In the medieval period, torpedo’s electrical properties were attributed to occult powers, while Renaissance physicians’ and scientists’ studied the anatomy and mechanical nature of the provoked shock paving the way for the discovery of the electrical nature of torpedo’s activity and the evolution of electrotherapy

OFTALMOLOŠKE OPSERVACIJE U TEKSTU CELIJA AURELIJANA O AKUTNIM I KRONIČNIM BOLESTIMA

Caelius Aurelianus’ Latin translation, De morbis acutis et chronicis, of Soranus of Ephesus’ original Greek work is a work devoted to internal medicine. Nevertheless, there are some observations about ocular pathologies which reveal the level of the knowledge at that time about the eye and their use as elements of pathological semiology.Latinski prijevod Celija Aurelijana De morbis acutis et chronicis, grčkoga originala Sorana iz Efeza, djelo je posvećeno internoj medicini. Unatoč tome ono obuhvaća pojedine opservacije o očnoj patologiji, koje otkrivaju razinu tadašnjega znanja o očima i njihovoj uporabi kao elemenata patološke semiologije

The eminent Italian scholar Pietro d’Abano (1250-1315) and his contribution in anatomy

Pietro d’Abano is recognized as a leading figure in the early history of European medical faculties. Translator and scholar, he translated and commented in Latin the doctrines of Greek and Arab physicians and philosophers having an ambitious attempt, to reconcile the opposing views of Arab medicine and Greek natural philosophy. Moreover he was one of the first to claim, three centuries before Harvey, that the heart is the source of blood vessels

Herophilus of Chalcedon (ca. 330-250 BC) and ocular anatomy. A review

Herophilus of Chalcedon (ca. 330-250 BC) was considered as one of the most important figures of anatomy during the antiquity. Apart from his other works in anatomy very important are also his observations in ocular anatomy. He discovered first the optic nerve and described four tunics in the eye
