1001 Sekercioglu, CaganCauses and consequences of bird extinctionsIncreased human domination of the planet has caused the declines and extinctions of countless species. Each species has not only intrinsic value, but ecological functions of organisms are also essential for the integrity of ecosystems that allow people to benefit from essential free ecosystem servic...2003-01-01
1002 Torti, Sylvia D.; Coley, Phyllis D.; Kursar, Thomas A.Causes and consequences of monodominance in tropical lowland forestsTropical canopy dominance in lowland, well-drained forests by one plant species is a long-standing conundrum in tropical biology. Research now shows that dominance is not the result of one trait or mechanism. We suggest that the striking dominance of Gilbertiodendron dewevrei in the Ituri Forest of ...Monodominance; Gilbertiodendron dewevrei; Ituri Forest; Understory2001
1003 Hartmann, Donald P.Cautionary note on the use of omega squared to evaluate the effectiveness of behavioral treatmentsEstimating the magnitude of treatment effects has been recommended as a solution to the problems associated with conventional hypothesis testing. In comparison to tradition statistical tests of treatment effectiveness, omega squared (ω2) and related magnitude of effect statistics provide a graduat...Magnitude of effects; omega squared1981
1004 Gluf, Wayne M.; Gottfried, Oren N.; Schmidt, Meic H.Cavernous hemangioma of the skull presenting with subdural hematomaCavernous hemangioma of the calvarium is a very rare disease, and patients usually present with headaches or a visible skull deformity.

1006 Sperry, John S.Cavitation fatigue - the weakening of cavitation resistance of xylem and its reversibilityXylem function is essential for the growth and survival of higher land plants. Xylem must not only be efficient under favorable conditions to facilitate high rates of stomatal conductance and carbon uptake, but it should also remain functional under drought conditions, when water potential (Ψ) dro...Cavitation fatigue; Drought; Pit membrane2003
1007 Henderson, Thomas C.CBCV: A CAD-based vision systemThe CBCV system has been developed in order to provide the capability of automatically synthesizing executable vision modules for various functions like object recognition, pose determinaion, quality inspection, etc. A wide range of tools exist for both 2D and 3D vision, including not only software...CBCV1990

1009 Davidson, Diane W.Cecropia and its biotic defensesIn all the world, the genus Cecropia is unrivaled for the number of myrmecophytes, or true "antplants" counted among its species (McKey & Davidson, 1993). Based on the proportion of Cecropia species producing Mullerian bodies in at least some parts of their distribution, myrmecophytes comprise the ...Myrmecophytes; Mullerian bodies; Pearl bodies2005
1010 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

1013 Carter, Tony M.; Smith, Kent F.Cell matrix methodologies for integrated circuit designA class of integrated circuit design and implementation methodologies is described. These techniques are unique in that they simultaneously model both function and interconnect using cells. These cells are designed such that cell adjacency normally implies interconnection. The absence of an interco...Integrated circuit design; Cell matrix1989
1014 Fowles, RichardCell phone effect on motor vehicle fatality rates: a Bayesian and classical econometric evaluationThis paper examines the potential effect of cell phones on motor vehicle fatality rates normalized for other driving related and socioeconomic factors. The model used is nonlinear so as to address both life-taking and life-saving attributes of cell phones. The model is evaluated using classical meth...2010
1015 Bastiani, MichaelCell-cell interactions during the migration of an identified commissural growth cone in the embryonic grasshopperOne of the fascicles of the posterior commissure of the embryonic grasshopper is pioneered by an individually identifiable neuron named Q1. Q1 initially grows along a longitudinal pathway established by another pioneer neuron, MPl, and then crosses to the midline, where it meets and fasciculates wi...Commissure; Pathfinding; Filopodia1993
1016 Gesteland, Raymond F.Cell-free synthesis of herpes simplex virus proteinsPolyribosomes isolated from herpes simplex virus type I (HSV-1)-infected cells have been used to program a eucaryotic cell-free translation system. At least 10 HSV-specific polypeptides, with apparent molecular weights of 25,000 to 160,000, are synthesized by wild-type HSV-infected polyribosomes.

1020 Bastiani, MichaelCentral projections of the stretch receptor neurons of crayfish: segmental gradients of synaptic probability and strengthThe 20 stretch receptor neurons (SRs) of the crayfish abdomen send axons into the CNS that then project both to the brain and to the last abdominal ganglion, G6 (Bastiani and Mulloney, 1988). In G6, we recorded intracellularly from different kinds of neurons postsynaptic to SR axons.Axons; Synapses; SR1988
1021 Bastiani, MichaelCentral projections of the stretch receptor neurons of crayfish: structure, variation, and postembryonic growthEach stretch receptor neuron (SR) of the crayfish abdomen projects from its peripherally located soma an axon that enters the CNS through the second nerve (N2) of its segmental ganglion. CoZ+ backfills of N2 revealed that this axon bifurcates, sending one branch to the brain and the other to the te...Abdomen; Axon; Ganglion1988
1022 Frederick, Jeanne M.Centrin 2 is required for mouse olfactory ciliary trafficking and development of ependymal cilia planar polarityCentrins are ancient calmodulin-related Ca2-binding proteins associated with basal bodies. In lower eukaryotes, Centrin2 (CETN2) is required for basal body replication and positioning, although its function in mammals is undefined.
