Corruption in an Unstable Environment∗

In this paper we study the influence of economic stability on the level of corruption in a country, where high stability is defined as a low level of variance in economic output growth. We present a political competition model with exogenous shocks to economic output where politicians can decide about the level of corruption and an election is held within the framework of a Bayesian game. Corru...

An alternative pathophysiological mechanism for unstable angina.

An unstable nuclear gene in phycomyces.

A gentic instability in Phycomyces is described that appears to be associated with a single nuclear gene, dar. The wild type is able to take up riboflavin and its toxic analogue, deaza-riboflavin, from nanomolar concentrations in the medium. The mutants are unable to take up riboflavin and are resistant to deaza-riboflavin. Forward and reverse mutation rates are estimated to be 4 x 10(-5) and 2...

A case Report of Cardiac Hydatid Cyst found during an Emergent Tamponade Surgery in an Unstable Patient

Cardiac hydatid cysts are uncommon and pericardial involvement is extremely uncommon. We report a rare case of a cardiac hydatid cyst that was surprisingly found during an emergent tamponade surgery in a woman. She was pale, febrile, ill and toxic and 300cc turbid and purulent fluid was drained. In taking history, it was found that the patient had six sheep dogs in her house. Laboratory analys...

Nucleation via an unstable intermediate phase.

The pathway for crystallization from dilute vapors and solutions is often observed to take a detour via a liquid or concentrated-solution phase. For example, in moist subzero air, droplets of liquid water form, which then freeze. In this example and in many others, an intermediate phase (here liquid water) is dramatically accelerating the kinetics of a phase transition between two other phases ...
