Third-generation Syphilis

A Case of Third-generation Syphilis.

Two Cases of Third-generation Syphilis.

The question whether third-generation syphilis does occur has in the past been the subject of much debate and controversy. The following criteria laid down by Fournier (1891) and Finger (1900) still provide the yardstick by which third-generation syphilis is judged: (1) Acquired syphilis must be demonstrated in the grandmother and preferably also in the grandfather. (2) Pre-natal as distinguish...

Third-generation syphilis and bilateral interstitial keratitis occurring in all the surviving members of two generations.

Physicians who have the opportunity of studying the results of a syphilitic infection on family units as well as on individuals must, on occasion, be forced to inquire how often and how seriously is third generation lues sought out, and whether third generation disease is as rare as is generally supposed. During the last 3 years I have encountered several cases of syphilis which I feel cannot b...

Third-generation prospect theory

We present a new theory of decision under uncertainty: third-generation prospect theory (PT). This retains the predictive power of previous versions of prospect theory, but extends that theory by allowing reference points to be uncertain while decision weights are specified in a rank-dependent way. We show that PT preferences respect a state-conditional form of stochastic dominance. The theory ...

Third generation photovoltaics

We review recent progress towards increasing solar cell efficiencies beyond the Shockley-Queisser efficiency limit. Four main approaches are highlighted: multi-junction cells, intermediate-band cells, hot carrier cells and spectrum conversion. Multi-junction cells use multiple solar cells that selectively absorb different regions of the solar spectrum. Intermediateband cells use one junction wi...
