We consider extensions of unital commutative rings. We define an extension R ↪→ S to be a p-extension if every principally generated ideal of S is generated by an element of R. Examples are plentiful and localizations of regular multiplicative sets are p-extensions. We develop the theory of pextensions.

Over the last two decades, the U.S. military has struggled to understand the center of gravity concept as developed by Carl von Clausewitz and to find practical ways to apply it. In the process, however, each of the services—shaped as they are by different roles, histories, and traditions—has brought individual perspectives to Clausewitz’s expression and redefined it in its respective image. Th...

[1] Iceland is a strong localized source of non-eruptive volcanic warming and cooling. Temperature trend maps show that this phenomenon is localized to an area of about twice that of Iceland. With altitude the area remains constant but the phenomenon weakens and changes sign upon passing through the tropopause. The effect’s magnitude implies a large positive feedback, according to a conventiona...

The performance of a phase recovery algorithm developed for speckle data collected using a pupil-plane mask has been investigated for use at near infrared wavelengths. The method, based on the radio-astronomical self-calibration technique, has been tested alongside a state-of-the-art implementation of the Knox-Thompson scheme using both simulated and real specklegrams. Our results indicate that...
