28 Couldwell, William T.Comment on Kitano, M. and Taneda, M.: Extended transsphenoidal approach to the anterior communicating artery aneurysm: aneurysm incidentally identified during macroadenoma resectionKitano and Taneda describe the successful clipping of an ACoA aneurysm via the transsphenoidal approach. There are limitations of the approach; most notable are the limited and narrow corridor and the relationship between the aneurysm and the optic chiasm, which may hinder full visualization of the ...Aneurysm; Transsphenoidal approach2007
29 Balasubramonian, RajeevCommit algorithms for scalable hardware transactional memoryIn a hardware transactional memory system with lazy versioning and lazy conflict detection, the process of transaction commit can emerge as a bottleneck. For a large-scale distributed memory system, we propose novel algorithms to implement commit that are deadlock- and livelock-free and do not empl...Commit algorithms; Scalable; Hardware; Transactional memory2007
30 Henderson, Thomas C.; Sikorski, ChristopherComputational sensor networksWe propose Computational Sensor Networks as a methodology to exploit models of physical phenomena in order to better understand the structure of the sensor network. To do so, it is necessary to relate changes in the sensed variables (e.g., temperature) to the aspect of interest in the sensor netw...Computational sensor networks2007
31 Liu, FengConfining P diffusion in Si by an As-doped barrier layerThe miniaturization of Si-based devices requires control of doping profile, which makes the understanding of dopant interaction and diffusion in Si critical. The authors have studied the effect of As doping on P diffusion in Si using first-principles calculations. The authors found a form of As-vaca...P diffusion; Silicon; Arsenic doping; As-doped barrier; Diffusion control2007

33 Beckerle, Mary C.Cytoskeleton-associated PDZ-LIM protein, ALP, acts on serum response factor activity to regulate muscle differentiationIn this report, an antisense RNA strategy has allowed us to show that disruption of ALP expression affects the expression of the muscle transcription factors myogenin and MyoD, resulting in the inhibition of muscle differentiation. Introduction of a MyoD expression construct into ALP-antisense cells...Skeletal muscle; PDZ-LIM protein; Actin; Actinin-associated LIM proteins; Serum response factor; Cytoskeletal architecture2007
34 Fernandez, Diego P.Deep-sea scleractinian coral age and depth distributions in the Northwest Atlantic over the last 225,000 yearsDeep-sea corals have grown for over 200,000 yrs on the New England Seamounts in the northwest Atlantic, and this paper describes their distribution both with respect to depth and time. Many thousands of fossil scleractinian corals were collected on a series o f cruises from 2003- 2005; by contrast,...Desmophyllum dianthus; Scleractinian coral; Seamounts; Northwest Atlantic2007
35 Farmer, Colleen G.Dendrobates auratus (green and black poison dart frog). Larval PredationDendrobates auratus was intentionally introduced onto the island of O'ahu, Hawai'i in 1932 from Taboga Island, Panama for mosquito control. Phelsuma laticauda was accidentally introduced from Madagascar in 1996 to the University of Hawaii at Manoa. Both species are well established in the Manoa Val...Dendrobates auratus; Phelsuma laticauda2007
36 Myers, Chris J.Design of a genetic muller C-elementSynthetic biology uses engineering principles to design circuits out of genetic materials that are inserted into bacteria to perform various tasks. While synthetic combinational Boolean logic gates have been constructed, there are many open issues in the design of sequential logic gates. One such g...2007
37 Ring, Terry Arthur; Eddings, Eric G.; Sarofim, Adel F.Determination of soot refractive index as a function of height in an inverse diffusion flameWith the scope of combustion diagnostics increasing, it is becoming ever more important for some of the more basic physical properties of soot to be addressed. Soot refractive index values were obtained as a function of height in a benzene inverse diffusion flame (IDF). The IDF was chosen for ease i...Inverse diffusion flame2007
38 Miller, Jan D.Development and application of centrifugal flotation systems in wastewater treatmentFlotation as a wastewater treatment technique is designed to remove all particles generally encountered as very fine emulsions, suspended solids, and colloids from wastewater. Historically, Dissolved Air Flotation (DAF) has been used to achieve this removal. More recently, other flotation techniques...Wastewater treatment; Centrifugal flotation; Liquid cyclone mixing; Hybrid centrifugal dissolved-air flotation; ASH; BAF; GEM; FF2007
39 Owen, William E.; Roberts, William L.; Ring, Terry ArthurDevelopment and validation of an automated thawing and mixing workcellWorking toward a goal of total laboratory automation, we are automating manual activities in our highest volume laboratory section. Because half of all specimens arriving in this laboratory section are frozen, we began by developing an automated workcell for thawing frozen specimens and mixing the t...Automated workcell; Laboratory automation2007
40 Berg, Cynthia A.; Smith, Timothy W.Developmental approach to psychosocial risk factors and successful agingSuccessful aging has been characterized as maintaining physical health (avoiding disease), sustaining good cognitive function, and having active engagement with other people and productive activities (Rowe 8c Kahn, 1998). Although these three factors are known to be interrelated, the field has large...2007
41 Yang, HaoriDigital spectroscopy systems for high rate events in active interrogation applicationsAbstract- Two digital spectroscopy systems have been developed to handle high rate events in active interrogation applications. In the first system, signal from a PMT is directly digitized by a digitizer and then processed on a PC offline, using deconvolution method. By bypassing the preamplifier, ...2007
42 Mcpherson, Brian JamesDirect simulation of fluid-solid mechanics in porous media using the discrete element and lattice-Boltzmann methodsA detailed understanding of the coupling between fluid and solid mechanics is important for understanding many processes in Earth sciences. Numerical models are a popular means for exploring these processes, but most models do not adequately handle all aspects of this coupling. This paper presents ...2007
43 Coley, Phyllis D.Disponibilidad de recursos y defensas de las plantas frente al herbivorismoEl grado de herbivorismo y la eficacia de las defensas muestran amplias variaciones en las especies de plantas.
