1 Gooch, Amy A.; Gooch, Bruce; Willemsen, Peter; Kniss, Joe; Riesenfeld, Richard F.; Shirley, Peter S.3D Line textures and the visualization of confidence in ArchitectureThis work introduces a technique for interactive walkthroughs of non-photorealistically rendered (NPR) scenes using 3D line primitives to define architectural features of the model, as well as indicate textural qualities. Line primitives are not typically used in this manner in favor of texture ma...Presentation graphics; Interactive walkthroughs2007
2 Olivera, Baldomero M.?O-Conotoxins inhibit NaV channels by interfering with their voltage sensors in domain-2The ?O-conotoxins MrVIA and MrVIB are 31-residue peptides from Conus marmoreus, belonging to the O-superfamily of conotoxins with three disulfide bridges. They have attracted attention because they are inhibitors of tetrodotoxin-insensitive voltage-gated sodium channels (NaV1.8) and could therefore ...2007

4 Whitaker, Ross T.A fast iterative method for a class of Hamilton-Jacobi equations on parallel systemsIn this paper we propose a novel computational technique, which we call the Fast Iterative Method (FIM), to solve a class of Hamilton- Jacobi (H-J) equations on massively parallel systems. The proposed method manages the list of active nodes and iteratively updates the solutions on those nodes u...Fast Iterative Method; FIM; Parallel systems2007
5 Mathews, V. JohnA minimax approach for the joint design of acoustic crosstalk cancellation filtersAbstract-This paper presents a method for jointly designing immersive audio rendering filters for a single listener using loudspeakers.

8 Miller, Jan D.Anisotropic character of talc surfaces as revealed by streaming potential measurements, atomic force microscopy, molecular dynamics simulations and contact angle measurementsA study of the interfacial properties of the basal plane and the edge surfaces of talc is described in this paper. The isoelectric points measured at two different crystallographic surfaces by the streaming potential method were found to be similar and exist at about pH 3.0. In the case of the edge...Talc; Interfacial properties; Hydration; Atomic force microscopy; Molecular dynamics simulations; Edge surface; Basal plane2007

10 Tasdizen, Tolga; Whitaker, Ross T.Automatic assembly of TEM mosaics and mosaic stacks using phase correlationThis paper discusses automatic Transmission Electron Microscopy (TEM) image registration, TEM slice assembly via tile mosaicking, and TEM volume assembly via slice to slice registration. Several algorithms are presented, including an algorithm for mosaic layout of an unordered set of tiles, an algor...2007
11 Jorgensen, ErikAxons break in animals lacking B-spectrinAxons and dendrites can withstand acute mechanical strain despite their small diameter. In this study, we demonstrate that β-spectrin is required for the physical integrity of neuronal processes in the nematode Caenorhabditis elegans. Axons in β-spectrin mutants spontaneously break.2007

13 Coley, Phyllis D.Beneficios y costos de defensa en un arbusto del neotrópicoLOS beneficios y costos son de importancia capital para las teorfas de optimization de las defensas de las plantas. El beneficio es la ganancia de aptitud para reducir el herbivorismo; el costo es la perdida de aptitud al comprometer recursos en defensa. Evaluamos los beneficios y los costos de def...Psychotria horizontalis; Isla de Barro Colorado; Costos de defense; Celdas de exclusion; Herbivorismo; Defensa de las plantas; Taninos; Dureza; Tropicos; Benefit; Beneficios2007
14 Schmidt, Meic H.Castleman disease of the spine mimicking a nerve sheath tumorCastleman disease is a rare lymphoproliferative disease of unknown cause. In most cases, afflicted patients present with a mediastinal mass although the disease may manifest in numerous other sites, including intracranially and rarely intraspinally. The authors report on the case of a 19-year-old wo...Castleman disease; Nerve sheath tumor2007
15 Couldwell, William T.; Jensen, Randy L.; Gillespie, David L.Celecoxib inhibits meningioma tumor growth in a mouse xenograft modelBackground: Treatments for recurrent meningiomas are limited. We previously demonstrated universal expression of COX-2 in meningiomas and dose-dependent growth inhibition in vitro with celecoxib, a COX-2 inhibitor. We therefore tested the effects of celecoxib on meningioma growth in a mouse xenograf...Meningioma; Cyclooxygenase-2; COX-2; Celecoxib2007
16 Stringfellow, Gerald B.; Sadwick, Laurence P.Chemical beam epitaxial growth of InP and GaP by using tertiarybutylbis (dimethylamino) phosphineWe report the growth of indium phosphide (InP) by using a chemical beam epitaxy (CBE) technique with the group V source tertiarybutylbis (dimethylamino) phosphine (TBBDMAP).

20 Ostafin, AgnesCombined deletion of mouse dematin-headpiece and ß-adducin exerts a novel effect on the spectrin-actin junctions leading to erythrocyte fragility and hemolytic AnemiaDematin and adducin are actin-binding proteins of the erythrocyte "junctional complex." Individually, they exert modest effects on erythrocyte shape and membrane stability, and their homologues are expressed widely in non-erythroid cells. Here we report generation and characterization of double knoc...2007

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
23 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.

24 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
25 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.
