B.c.c.-f.c.c. allotropy, F-bands,and metallization in xenon and krypton

APW-Xα calculations of a f.c.c.-b.c.c. phase transition in Xe prior to metallization give P ? 950 kbar, contrary to the 820 kbar result of Hama and Matsui; their use of non-touching APW spheres (f.c.c.) may be the crucial difference. Hartree-Fock plus correlation calculations in Kr indicate that f-bands play no role in rare gas crystal metallization.     

Chaos and Coarse Graining in Statistical Mechanics,by P. Castiglione,M. Falcioni,A. Lesne and A. Vulpiani

For 20 years, cantilevers have been used in different research fields as fast, accurate and label-free sensors in liquid, gas, air and vacuum. Due to their small size, they can be integrated into microfluidic systems and offer possibilities for various applications in lab-on-chip technology. Furthermore, multiple cantilevers, the so-called cantilever arrays, provide a direct internal reference during the measuring process and enable the parallel monitoring of several different analytes. This review provides a general introduction into the history and theory of cantilever sensors, with an emphasis on biological monitoring applications as opportunities for classical and quantum physics. Furthermore, it includes recent developments in novel transduction principles and applications, and discusses future prospects.     

Probability,Random Processes,and Statistical Analysis,by H. Kobayashi,B.L. Mark and W. Turin

This article describes the scientific objectives, the scientific and operational plans and the observational programme of the international Atlantic Tropical Experiment in which some 70 countries pclrticipated during Jun-September 1974. The main aim waa to make, for the first time, an intensive study of the structure, evolution and transport properties of tropical weather systems and their role in the global circulation of the atmosphere as a whole. Some preliminary results are described but it will be two or three years before the vast mass of data is fully processed and analysed and made available in the form of validated data sets for detailed researoh studies and for input to numerical models. However, there is already good reason to believe that the major scientific objectives of the experiment will be achieved and that the knowledge gained will lead to improved weather forecasting both in the tropics, and in middle latitudes where accurate predictions for more than about three days ahead may not be possible without taking into account the import of heat and moiature from the tropical oceans through the large convective clouds of the tropical atmosphere.
