This article reconstructs the diagnostic act of the French pox in the French-disease hospital of sixteenth-century Augsburg. It focuses on how the participants in the clinical encounter imagined the configuration of the pox and its localization in the human body. Of central importance for answering this question is the early modern conception of physical signs. It has been argued that it was du...

A radiological sign can sometimes resemble a particular object or pattern and is often highly suggestive of a group of similar pathologies. Awareness of such similarities can shorten the differential diagnosis list. Many such signs have been described for X-ray and computed tomography (CT) images. In this article, we present the most frequently encountered plain film and CT signs in chest imagi...

In a study of 133 anaemic and 111 nonanaemic hospital patients pallor of recent onset was the only symptom which was significantly associated with the severity of the anaemia. Dizziness in acute blood loss anaemia, and anorexia and painful tongue in vitamin-B12 deficiency, were the only symptoms which might be helpful in diagnosing the type of anaemia. The frequency of glossitis in patients wit...

This paper's central concern is with signs of fascism in recent political developments in a number of European countries and the United States. It takes the reader back to earlier periods in European and American history when this same anguished question was raised. Thus a longer intellectual history of concerns about the viability of democratic systems is drawn to guide us in our current polit...

In this work, we formally proved Descartes Rule of Signs, which relates the number of positive real roots of a polynomial with the number of sign changes in its coefficient list. Our proof follows the simple inductive proof given by Arthan [1], which was also used by John Harrison in his HOL Light formalisation. We proved most of the lemmas for arbitrary linearly-ordered integrity domains (e.g....

Object-oriented design patterns have been one of the most important and successful ideas in software design over the last ten years, and have been well adopted both in industry and academia. A number of open research problems remain regarding patterns, however, including the differences between patterns, variant forms of common patterns, the naming of patterns, the organisation of collections o...

A 13-year-old boy presented with sudden-onset give-away weakness, nonanatomic sensory loss, and posturing of the right foot followed by episodic left leg tremor, relatively unchanged for 14 months prior to this evaluation. The right first toe was fixed in extension; the others in flexion. Although there was resistance to passive plantar flexion, such movement occurred spontaneously upon forced ...

While gloom surrounds the prospects of many global fisheries, one species seems to have benefited from a range of, often controversial, conservation measures. North Sea cod, once on the brink of collapse as a result of decades of overfishing, looked set for the same fate as cod on the Grand Banks off northeast America, but new evidence suggests numbers are now recovering. In a rare positive con...

Radiologic signs are recognizable, characteristic patterns used to describe abnormalities visualized on imaging modalities that ultimately aid in the diagnosis and subsequent treatment of disease. This pictorial essay discusses 23 classic roentgenographic signs used in thoracic imaging. Its purpose is to be used as an educational review for residents, whether they are beginning their training o...

Abstract : Our research aims at discovering useful knowledge from the large collection of satellite images of typhoons using data mining approaches. In addition, this paper discusses more ambitious challenges, namely the discovery of the signs of infrequent but relevant events from typhoon cloud patterns observed from satellites. For this purpose, we have built the typhoon image collection of a...
