Hooking some stem‐group “worms”: fossil lophotrochozoans in the Burgess Shale
Authors: Butterfield Nicholas J. 
Published: November 2006

AbstractThe fossil record plays a key role in reconstructing deep evolutionary relationships through its documentation of the early diverging stem groups leading to extant phyla. In the middle Cambrian Burgess Shale, two famously problematic worms, Odontogriphus and Wiwaxia, have recently been reinterpreted as stem‐group molluscs based on their shared expression of a putative radula and putative ctenidia in Odontogriphus.1 More detailed analysis of these fossil structures, however, reveals pronounced anatomical and histological discrepancies with molluscan analogues, such that they are more reliably interpreted as primitive features of the superphylum Lophotrochozoa. In the absence of any obviously derived characters, Odontogriphus could be placed in the stem group of the Lophotrochozoa or on the stem of any of its constituent phyla, whereas the dorsal covering of chaetae in Wiwaxia identifies it as a stem‐group polychaete. Despite their close relationship, these two jawed, segmented worms could conceivably represent the early stages of two separate phyla. BioEssays 28: 1161–1166, 2006. © 2006 Wiley Periodicals, Inc.
Deeper into the maize: new insights into genomic imprinting in plants
Authors: Scott Rod J. , Spielman Melissa 
Published: November 2006

AbstractCurrent models for regulation of parent‐specific gene expression in plants have been based on a small number of imprinted genes in Arabidopsis. These present repression as the default state, with expression requiring targeted activation. In general, repression is associated with maintenance methylation of cytosines, while no role has been found in Arabidopsis imprinting for de novo methylation—unlike the case in mammals. A recent paper1 both reinforces and challenges the model drawn from Arabidopsis. Methylation patterns of two imprinted loci in maize were tracked from gametes to offspring, enabling an exploration of the timing of imprinting. For one gene, fie1, the results were as expected: parent‐specific methylation patterns were inherited from the three types of gamete: egg, central cell and sperm. The behaviour of fie2, however, was a surprise: no alleles were methylated in the gametes, although paternally contributed fie2 is methylated and silent in the endosperm, indicating that, in some cases, plant imprinting requires de novo DNA methylation. This work significantly broadens our understanding of plant imprinting and points to a greater diversity in imprinting mechanisms than has previously been appreciated.

Sorting and pooling strategy: A novel tool to map a virus proteome for CD8 T‐cell epitopes
Authors: Ay Bernhard , Streitz Mathias , Boisguerin Prisca , Schlosser Andreas , Mahrenholz Carsten C. , Schuck Sebastian D. , Kern Florian , Volkmer Rudolf 
Published: November 2006

AbstractHuman cytomegalovirus (CMV) is a major cause of morbidity in immunocompromised individuals. However, no efficient vaccine has been developed to date. Identification of T‐cell target proteins and epitopes is crucial not only for developing a successful immunization strategy, but also for new approaches using adoptive transfer of antigen‐specific T‐cells. The CMV genome has more than 200 open reading frames potentially coding for as many proteins. Here, we describe a robust, fast, and simple SPOT synthesis strategy, which allowed us to micro‐synthesize every possible CD8 T‐cell epitope in the entire potential CMV proteome. So far, 9069 of these peptides have been tested in an ex vivo T‐cell stimulation assay. As well as confirming a number of previously known epitopes, we identified several new ones. © 2006 Wiley Periodicals, Inc.

A 2D–3D integrated tabletop environment for multi‐user collaboration
Authors: Nakashima Kousuke , Machida Takashi , Kiyokawa Kiyoshi , Takemura Haruo 
Published: November 2006

AbstractThis paper proposes a novel tabletop display system for natural communication and flexible information sharing. The proposed system is specifically designed to integrate two‐dimensional (2D) and three‐dimensional (3D) user interfaces by using a multi‐user stereoscopic display, IllusionHole. The proposed system takes awareness into consideration and provides both 2D and 3D information and user interfaces. On the display, a number of standard Windows desktop environments are provided as personal workspaces, as well as a shared workspace with a dedicated graphical user interface. In the personal workspaces, users can simultaneously access existing applications and data, and exchange information between personal and shared workspaces. In this way, the proposed system can seamlessly integrate personal, shared, 2D, and 3D workspaces with conventional user interfaces and effectively support communication and information sharing. To demonstrate the capabilities of the proposed display system, a modeling application was implemented. A preliminary experiment confirmed the effectiveness of this system.

Statistical signatures used with principal component analysis for fault detection and isolation in a continuous reactor
Authors: Miller John P. 
Published: November 2006

AbstractPrincipal component analysis (PCA) is a technique widely used in industrial process control for data analysis and reduction. A score discriminant can be used in conjunction with a PCA model to differentiate between the normal operating condition and an abnormal condition. To illustrate application of these analytical techniques, raw data is collected from a high fidelity simulation of a continuous chemical reactor for both the normal operating condition, and several different fault conditions. A PCA model and score discriminant are applied to analyze the raw data, but this approach does not reliably differentiate between all process conditions. To improve the differentiation, an alternative model is developed using the statistical signatures of mean and standard deviation, such as are computed in some present day intelligent field devices. The new PCA score discriminant model based on statistical signatures produces a much clearer differentiation between all process conditions. Copyright © 2006 John Wiley & Sons, Ltd.
Quality assessment of the results obtained by multivariate curve resolution analysis of multiple runs of gasoline blending processes
Authors: Jaumot Joaquim , Menezes José C. , Tauler Romà 
Published: November 2006

AbstractThis work presents a quality assessment study of the results obtained by multivariate curve resolution of multiple runs of gasoline blending processes. This evaluation is performed by noise propagation studies using resampling methods and by calculation of feasible bands due to rotational ambiguities. Results showed that combination of matrix augmentation and use of constraints strategies during alternating least squares optimization minimize both rotational ambiguities and error propagation effects in the resolved solutions. The proposed approach is tested for simulated and experimental data sets obtained in the study of blending processes of gasolines monitored by NIR spectroscopy.

Effects of pre‐processing of Raman spectra on in vivo classification of nutrient status of microalgal cells
Authors: Heraud Philip , Wood Bayden R. , Beardall John , McNaughton Don 
Published: November 2006

AbstractRaman spectra were obtained from cells of the chlorophyte unicellular eukaryotic alga Dunaliella tertiolecta, which had been grown either under nutrient‐replete conditions or starved of nitrogen for 4 days. Spectra were rich in bands which could all be attributed to either chlorophyll a or β‐carotene. A cursory examination of the differences between the spectra of replete and starved cells indicated a decline in chlorophyll a and an increase in β‐carotene in chlorophytes. Unprocessed spectra showed pronounced baseline effects. A variety of pre‐processing techniques were used in an attempt to visualise the spectral, and hence chemical, differences in the transformed data and perform classification based upon these differences. Six types of spectral pre‐processing were compared: baseline correction with vector normalisation; Multiplicative Scatter Correction (MSC), Extended Multiplicative Signal Correction (EMSC); Standard Normal Variate (SNV); and vector normalised 1st and 2nd derivative spectra. Results for Soft Independent Modelling of Class Analogy (SIMCA) and Partial Least Squares (PLS) discriminant analysis were compared. All pre‐processing methods allowed spectral differences between N‐replete and N‐starved spectra to be visualised, with derivatives and EMSC scoring the lowest RMSEC and RMSEV values with PLS and also the best overall classification results. SIMCA was not suited to classifying the nutrient classes under any of the pre‐treatments, due to the small model distances involved. Copyright © 2006 John Wiley & Sons, Ltd.
An exploratory chemometric study of 1H NMR spectra of table wines
Authors: Larsen Flemming H. , van den Berg Frans , Engelsen Søren B. 
Published: November 2006

AbstractIn this paper an exploratory study of 40 table wines by proton nuclear magnetic resonance spectroscopy and chemometric region‐selection methods is presented. Several components of wine have been identified and quantified. It is demonstrated how signal alignment procedures were utilized to compensate for pH effects in the NMR spectra prior to the chemometric data modeling. The analysis included region selection by interval partial least squares for regression to reference data obtained from infrared spectroscopy. Accurate calibration models to the contents of ethanol, glycerol, lactic acid, methanol and malic acid were established. For the more general combined glucose/fructose infrared reference backwards interval partial least squares was introduced for optimal interval selection in calibration. The aim of the paper is to show how pre‐processing and region‐selection methods can assist in interpretation and quantification of chemical shift multiplets in 1H NMR spectra of complex biological systems. The extension to NMR metabolomics is straightforward. Copyright © 2006 John Wiley & Sons, Ltd.
