A calibration ¢ is a differential form on a Riemannian manifold with two additional properties. First, the form should be closed under exterior differentiation. Second, it should be less than or equal to the volume form on each oriented submanifold (of the same dimension as the degree of the form ¢). Each calibration ¢ determines a geometry of submanifolds, namely those oriented submanifolds fo...

Technics and Informatics in Education

Pneumatic circular manipulator is a new experimental facility developed for testing different control methods and energy efficiency of automated systems with compressed air as a working medium. Also, the manipulator has the ability of remote control, via the Internet and thereby it is an important didactic tool for teaching in the field of pneumatic control with multiple actuators. In this pape...

Alexander Sulakvelidze, Chief Scientist at Intralytix and one of its co-founders, says phages are a very safe and natural way of protecting food against bacteria. “The concept of using phages for improving food safety is based on simply applying phages back onto the foods in the right concentration, at the right place, and at the right time,” Sulakvelidze explains. “Thus, applying lytic phages ...

Attaching handles to Bryant surfaces

Complete minimal surfaces and constant mean curvature surfaces in Euclidean or hyperbolic space have been the object of much attention in recent years and particular efforts have been devoted in understanding the moduli space of such surfaces. More precisely, the surfaces we are interested in are complete, noncompact surfaces which may or may not be embedded but enjoy the somehow weaker, and sl...
