A síndrome de Sheehan refere-se ao hipopituitarismo secundário a necrose hipofisária devido hipotensão grave precipitada por hemorragia pós parto. Sua apresentação pode ser forma aguda ou crônica, sendo esta última caráter insidioso, com sintomas inespecíficos, levando, frequentemente, um diagnóstico tardio. investigação requer uma história obstétrica compatível parto, evoluindo agalactia e ame...

We illustrate the corrosive e¤ect of even small amounts of adverse selection in an asset market and how it can lead to the total breakdown of trade. The problem is the failure of “market con…dence”, de…ned as approximate common knowledge of an upper bound on expected losses. Small probability events can unravel market con…dence. We discuss the role of contagious adverse selection and the proble...

Seeing someone plunge into an ice-cold bath induces feelings of cold. However, it was recently demonstrated that ie ing another’s skin temperature change also induces a small congruent temperature change in the observer. This synchronization suggests topdown influences on peripheral temperature regulation mechanisms and lends supports to somatic-simulation theories of inter-subjectivity.

When is a person with a cold contagious? A couple of friends, who are put off when I keep my distance from their sneezing and coughing, insist one is only contagious a week or so before symptoms appear. In the back of my memory is the idea that one remains contagious until a few days *after* primary symptoms disappear. I'm not usually so concerned about this, but I'm coping with a couple of oth...

We consider the target set selection problem. In this problem, a vertex is active either if it belongs to a set of initially activated vertices or if at some point it has at least k active neighbors (k is identical for all vertices of the graph). Our goal is to find a set of minimum size whose activation will result with the entire graph being activated. Call such a set contagious. We prove tha...
