Gyrokinetic particle-in-cell (PIC) simulation is an important tool for studying low-frequency (! !ci) plasma instabilities and the associated transport of particles and heat in tokamaks. In spite of the e ciency gained by not following ion cyclotron motion, more e ciency is needed in performing simulations on a transport timescale: using 1 million particles in a system of 64 128 32 grid cells, ...

One of the main challenges of the Ozone project is to bring together many different technologies into a single architecture dedicated to Ambient Intelligence (AmI). The present document provides a broad inventory of relevant technologies. For each of the technologies identified, the characteristics, the most recent advances (state of the art, SOTA) and the challenges are described.

We exhibit an efficient auction (an auction that maximizes surplus conditional on all available information). For private values, the Vickrey auction (for one good) or its Groves-Clarke extension (for multiple goods) is efficient. We show that the Vickrey and Groves-Clarke auctions can be generalized to attain efficiency when there are common values, if each buyer’s information can be represent...

Many elite athletes believe that training at altitude improves sea level performance. Yet the scientific evidence, such as it is, would seem to refute this, suggesting that the athlete’s trust may be misplaced. However, these scientific studies do not exclude the possibility that altitude training might produce an effect (<1%) that is too small to be detected by current research methods, but wh...

BACKGROUND Antibody cross-reactivity complicates differential diagnosis of human immunodeficiency virus (HIV) type 2 (HIV-2) using standard serologic screening and confirmatory tests for HIV. HIV type 1 (HIV-1) viral load testing does not detect HIV-2. Although HIV-2 is, in general, less pathogenic than HIV-1, it can lead to immunosuppression and clinical AIDS, and there are important differenc...

The above list contains the names and thesis titles of recipients of doctoral degrees in the mathematical sciences (July 1, 1999, to June 30, 2000) reported in the 2000 Annual Survey of the Mathematical Sciences by 237 departments in 158 universities in the United States. Each entry contains the name of the recipient and the thesis title. The number in parentheses following the name of the univ...

Aprocess for propagating a pathogen in a three-dimensional tissue mass cultured at microgravity conditions in a culture vessel containing culture media and a culture matrix is provided. The three-dimensional tissue mass is inoculated with a pathogen and pathogen replication in the cells of the tissue mass achieved. 20 Claims, 3 Drawing Sheets https://ntrs.nasa.gov/search.jsp?R=20080006922 2017-...

Polyembryonic wasps are parasitoids that lay their eggs inside the bodies of other insects. These eggs then undergo a clonal phase of development that results in production of multiple genetically identical offspring. Copidosoma floridanum produces up to 3000 morula stage embryos that form an assemblage called a polymorula. Many aspects of C. floridanum development are well studied but comparat...

The massive increase in nucleotide sequence information available in public and private databases, coupled with advances in mass spectrometry (MS) and the associated search algorithms, have provided the basis for the emerging field of proteomics. The recent announcement of 35 000 or so genes in the human genome was on the low side of the number predicted. Yet, it re-affirms the view that cellul...
