Proceedings of the 8th Cologne-Twente Workshop on Graphs and Combinatorial Optimization

International audienceThe Cologne-Twente Workshop (CTW) on Graphs and Combinatorial Optimization started off as a series of workshops organized bi-annually by either Köln University or Twente University. As its importance grew over time, it re-centered its geographical focus by including northern Italy (CTW04 in Menaggio, on the lake Como and CTW08 in Gargnano, on the Garda lake). This year, CTW (in its eighth edition) will be staged in France for the first time: more precisely in the heart of Paris, at the Conservatoire National d’Arts et Métiers (CNAM), between 2nd and 4th June 2009, by a mixed organizing committee with members from LIX, Ecole Polytechnique and CEDRIC, CNAM

Digital Single-Cell Analysis of Plant Organ Development Using 3DCellAtlas

Diverse molecular networks underlying plant growth and development are rapidly being uncovered. Integrating these data into the spatial and temporal context of dynamic organ growth remains a technical challenge. We developed 3DCellAtlas, an integrative computational pipeline that semiautomatically identifies cell types and quantifies both 3D cellular anisotropy and reporter abundance at single-cell resolution across whole plant organs. Cell identification is no less than 97.8% accurate and does not require transgenic lineage markers or reference atlases. Cell positions within organs are defined using an internal indexing system generating cellular level organ atlases where data from multiple samples can be integrated. Using this approach, we quantified the organ-wide cell-type-specific 3D cellular anisotropy driving Arabidopsis thaliana hypocotyl elongation. The impact ethylene has on hypocotyl 3D cell anisotropy identified the preferential growth of endodermis in response to this hormone. The spatiotemporal dynamics of the endogenous DELLA protein RGA, expansin gene EXPA3, and cell expansion was quantified within distinct cell types of Arabidopsis roots. A significant regulatory relationship between RGA, EXPA3, and growth was present in the epidermis and endodermis. The use of single-cell analyses of plant development enables the dynamics of diverse regulatory networks to be integrated with 3D organ growth

The Effect of Color Coding Exterior Letters of Words on Reading Fluency and Decoding Ability in Intermediate Students Who Read below Grade Level

The purpose of this true experimental, posttest-only control-group design was to determine if the color coding of exterior letters affects the fluency and decoding ability among fourth grade students who were below grade level in reading. If color coding exterior letters is an effective intervention, then struggling readers could utilize this intervention to improve their reading fluency and decoding abilities. Participants were selected from a random sample of 102 public school students who were below grade level in reading. The participants were from a district in the southeast United States. Each student was randomly assigned to either an experimental or control group. Both groups received identical tests from the Houghton Mifflin (2009) diagnostic assessment in real word decoding, pseudoword decoding, and fluency, except that the exterior letters of words were colored blue for the treatment group, while all letters were black for the control group. The real word decoding assessment revealed no statistically significant difference between the mean scores of the control group and treatment group. There was a statistically significant difference between the mean scores of the control group and treatment group for the pseudoword decoding assessment and fluency assessment. While current research indicates that the exterior letters of a word play an essential role when reading, based on a review of the literature, including searches from ERIC (Ebsco), ETS Online Research Library, Education Research Complete, Children’s Literature Comprehensive Database, and ProQuest Education Journals, there are currently no color interventions that assist readers in focusing on exterior letters. Future research should focus on conducting follow up studies on the effectiveness of this intervention and test the effectiveness of color coding other morphological elements of words
