  • Due to its superiority such as low access latency, low en- ergy consumption, light weight, and shock resistance, the success of flash memory as a storage alternative for mobile computing devices has been steadily expanded into personal computer and enterprise server markets with ever increas- ing capacity of its storage. As it has been witnessed in the past several years, two-fold annual increase in the density of NAND flash memory is expected to continue until year 2012 [11].

  • Bioinformatics is an emerging and rapidly growing area of science. Not sur- prisingly, there is tremendous lag time between the state of knowledge and the publication of manuals for those who need to fathom the basic knowledge and apply it in problem solving. Mr. Rashidi and Dr. Buehler have found a way to address these needs. Their book provides excellent, timely, and easy- to-understand information and advice for those without a great...

  • These limitations arise because the P2P world is lacking in the areas of semantics, data transformation, and data relationships, yet these are some of the core strengths of the data management community. Queries, views, and integrity constraints can be used to express relationships between existing objects and to define new objects in terms of old ones. Complex queries can be posed across multiple sources, and the results of one query can be materialized and used to answer other queries.

  • Endocrine disruptors function by: (i) Mimicking the action of a naturally-produced hormone, such as estrogen or testosterone, thereby setting off similar chemical reactions in the body; (ii) Blocking hormone receptors in cells, thereby preventing the action of normal hormones; or (iii) Affecting the synthesis, transport, metabolism and excretion of hormones, thus altering the concentrations of natural hormones.

  • As an example of how queries are executed, consider the query shown in Figure 5. In Figure 6, the processes used to execute the query are shown along with the flow of data between the various processes for a Gamma configuration consisting of two processors with disks and two processors without disks. Since the two input rela- tions A and B are partitioned across the disks attached to processors P1 and P2, selection and scan operators are ini- tiated on both processors P1 and P2.

  • Despite its importance in plant metabolism, no sequences of higher plant ATP-dependent phosphofructokinase (EC 2.7.1.11) are annotated in the databases. We have purified the enzyme from spinach leaves 309-fold to electrophoretic homogeneity. The purified enzyme was a homotetramer of 52 kDa subunits with a specific activity of 600 mUÆmg )1 and aKmvalue for ATP of 81 lm.

  • By typing into databases such as Medline or PubMed the word “lipoprotein” one gets more than 100.000 hits that highlight the common interest in this topic. It is actually impossible to cover all aspects of lipoprotein structure, function, metabolism and pathophysiology in one issue like the present volume, but attempts have been made to concentrate on topics that are in focus of current lipoprotein research. These topics have been divided into 10 sections.
