Authors: Wang Yubo , Veluvolu Kalyana C , Lee Minho 
Published: November 2013

Abstract

Background
Time-Frequency analysis of electroencephalogram (EEG) during different mental tasks received significant attention. As EEG is non-stationary, time-frequency analysis is essential to analyze brain states during different mental tasks. Further, the time-frequency information of EEG signal can be used as a feature for classification in brain-computer interface (BCI) applications.

Methods
To accurately model the EEG, band-limited multiple Fourier linear combiner (BMFLC), a linear combination of truncated multiple Fourier series models is employed. A state-space model for BMFLC in combination with Kalman filter/smoother is developed to obtain accurate adaptive estimation. By virtue of construction, BMFLC with Kalman filter/smoother provides accurate time-frequency decomposition of the bandlimited signal.

Results
The proposed method is computationally fast and is suitable for real-time BCI applications. To evaluate the proposed algorithm, a comparison with short-time Fourier transform (STFT) and continuous wavelet transform (CWT) for both synthesized and real EEG data is performed in this paper. The proposed method is applied to BCI Competition data IV for ERD detection in comparison with existing methods.

Conclusions
Results show that the proposed algorithm can provide optimal time-frequency resolution as compared to STFT and CWT. For ERD detection, BMFLC-KF outperforms STFT and BMFLC-KS in real-time applicability with low computational requirement.

AbstractBackgroundAlpha-synuclein is a key protein implicated in the pathogenesis of Parkinson's disease (PD). It is the main component of the Lewy bodies, a cardinal neuropathological feature in the disease. In addition, whole locus multiplications and point mutations in the gene coding for alpha-synuclein lead to autosomal dominant monogenic PD. Over the past decade, research on PD has impelled the development of new animal models based on alpha-synuclein. In this context, transgenic mouse lines have failed to reproduce several hallmarks of PD, especially the strong and progressive dopaminergic neurodegeneration over time that occurs in the patients. In contrast, viral vector-based models in rats and non-human primates display prominent, although highly variable, nigral dopaminergic neuron loss. However, the few studies available on viral vector-mediated overexpression of alpha-synuclein in mice report a weak neurodegenerative process and no clear Lewy body-like pathology. To address this issue, we performed a comprehensive comparative study of alpha-synuclein overexpression by means of recombinant adeno-associated viral vectors serotype 2/7 (rAAV2/7) at different doses in adult mouse substantia nigra.ResultsWe noted a significant and dose-dependent alpha-synucleinopathy over time upon nigral viral vector-mediated alpha-synuclein overexpression. We obtained a strong, progressive and dose-dependent loss of dopaminergic neurons in the substantia nigra, reaching a maximum of 82% after 8 weeks. This effect correlated with a reduction in tyrosine hydroxylase immunoreactivity in the striatum. Moreover, behavioural analysis revealed significant motor impairments from 12 weeks after injection on. In addition, we detected the presence of alpha-synuclein-positive aggregates in the remaining surviving neurons. When comparing wild-type to mutant A53T alpha-synuclein at the same vector dose, both induced a similar degree of cell death. These data were supported by a biochemical analysis that showed a net increase in soluble and insoluble alpha-synuclein expression over time to the same extent for both alpha-synuclein variants.ConclusionsIn conclusion, ourin vivodata provide evidence that strong and significant alpha-synuclein-induced neuropathology and progressive dopaminergic neurodegeneration can be achieved in mouse brain by means of rAAV2/7.

Proactive ecology for the Anthropocene
Authors: Chapin F. Stuart , Fernandez Erica 
Published: November 2013

Abstract
The rapid, directional global changes that characterize the Anthropocene provide unprecedented opportunities for ecologists and other scientists to discover new paradigms that shape our understanding of the ways that the world is changing. These paradigms will likely focus more strongly on interactions, feedbacks, thresholds, and model uncertainty than on steady-state dynamics and statistical uncertainty. We advocate a shift in ecology and other disciplines to a more proactive leadership role in defining problems and possibilities in a rapidly changing world rather than being relegated to a reactive role of trying to fix the problems after the horse has left the barn. This requires not only renewed commitment by ecologists (and other citizens) to a more proactive ethic of environmental citizenship but also institutional changes in education, the scientific review and funding processes, and promotion and tenure processes to encourage and celebrate those who seek to shape trajectories toward greater ecosystem and social resilience and well-being.

Published: November 2013

Abstract
Mill residues obtained from wood processing industries are potentially important feedstocks for the wood-based bioenergy industry. Although many mills recognize the value of their residue as an integral fuel for energy production, some recent studies suggest that ample mill residues are available to expand wood-based bioenergy in United States. This study analyzed factors that influence the availability of residues from mills in Mississippi. Information pertaining to available residues from forest products industries in Mississippi was obtained by a mail survey instrument. Generalized least square and Tobit models were used to analyze the data. Results indicated that availability of residues was higher in primary wood processing manufacturers than secondary manufacturers and that feedstocks availability would be higher if wood-based bioenergy firms were located near larger, year-round, forest products industry operations. Residue availability may be constrained by lack of awareness regarding market opportunities for bioenergy products. The study results are useful for entrepreneurs interested in creating sustainable bioenergy production in Mississippi.

Aim. To summarize practical experience of insulin pump therapy (IPT) in child population of Krasnoyarsk and to assess its efficacy for treatment of type 1 diabetes mellitus (T1DM) in paediatrics. Materials and Methods. We performed a comparative analysis of clinical and laboratory data from 48 children with T1DM prior to and after 6-12 months of IPT. Results. IPT yielded fourfold decrease in complaints of hyperglycemia and labile glycemia without concurrent increase in reports of severe hypoglycemia. We observed a trend for lowering of mean HbA1c levels, where 65% of patients showed positive dynamics in comparison with the period of multiple daily injection regimen. Interestingly, after 6-12 months of IPT, insulin requirement dropped in most patients. Conclusion. Our data support clinical efficiency and safety of IPT, as well as superiority of this treatment over multiple daily injection regimen. We conclude that IPT is a treatment of choice for children with T1DM.
Selenomethionine metabolism and its toxicity in yeast
Authors: Kitajima Toshihiko , Chiba Yasunori 
Published: November 2013

AbstractThe importance of selenium for organisms can be explained by its existence as selenocysteine in the catalytic centers of glutathione peroxidase and thioredoxin reductase. Another selenoamino acid, selenomethionine, is the major form of selenium in foods, and organisms that require selenium as a nutrient directly metabolize selenomethionine to a reactive form of selenium or store it in general proteins. Selenium is recognized as an essential nutrient for human and animal health; however, its excessive uptake harms mammals and the cytotoxic mechanism of selenium remains unclear. Recent progress in the development of selenium-enriched yeast and selenomethionine-resistant mutant to produce selenomethionine-containing proteins for X-ray crystallography has provided new insights into the molecular mechanism of selenomethionine toxicity. In this review, we describe the metabolism of seleno-compounds in yeast and discuss the cytotoxicity caused by selenomethionine against yeast from a metabolic viewpoint.

Published: November 2013

Abstract
We study the Mahler measure of some three-variable polynomials that are conjectured to be related to
L-functions of elliptic curves at s = 3 by Boyd. The connection with L-functions can be explained with the use of a regulator and a result of Goncharov. Finally, we prove a relationship between two formulas.
Autotopies and quasigroup identities: New aspects of non-associative division algebras
Authors: Darpö Erik , Pérez Izquierdo José Maria 
Published: November 2013

Abstract
In this article, we explore new aspects in the classification of non-associative division
algebras. By a detailed study of the representations of the Lie group of autotopies of real division
algebras we show that, if the group of autotopies has a sufficiently rich structure, then
the algebra is isotopic to one of the classical real division algebras. This turns out to be
the case for large classes of real division algebras, including many that are defined by
identities.
In several cases, a classification up to isomorphism can be worked out from this
information.
Les enfances de Perceval dans le Tristan en prose: jeunesse du héros et genèse du texte
Authors: de Carné Damien , Ferlampin-Acher Christine 
Published: November 2013

Résumé:
Les enfances de Perceval racontées par le Tristan
en prose mettent au jour différents problèmes. Inspirées par le Lancelot ou recopiées de lui, selon la version du Tristan que l’on considère, elles ont été généralement jugées comme une simple digression. En outre, cette suite d’épisodes est impliquée dans les relations complexes entre le Tristan et le cycle Post Vulgate, dans la mesure où ce dernier donne sous la même forme une partie de ces aventures. Jetant un nouveau regard sur la version V.I des enfances de Perceval, cette étude montre que la perception d’un écart narratif doit être relativisée. La présentation de Perceval et du meurtre de ses frères s’insère bien dans le Tristan (refus de la transcendance du Graal, dégradation progressive de la cour d’Arthur), ce que confirme une comparaison serrée avec le Lancelot. Du point de vue de la tradition textuelle, sans pouvoir trancher absolument entre les opinions opposées émises par le passé, cette étude réexamine la possibilité que la première version de ces aventures ait été d’origine tristanienne, bien que la forme sous laquelle elle nous est parvenue soit manifestement un développement de la Post Vulgate. En effet, dans ce type de textes mouvants, réfléchir à l’identité textuelle (identité douteuse pour la Post Vulgate, ou du moins la Folie Lancelot) et la matière propre de ces différents romans complète utilement les indices purement philologiques – et facilement contradictoires.
Arthur in Manuscript in Renaissance France: The Case of Ysaïe le Triste, Gotha, MS A 688
Authors: Taylor Jane H. M. 
Published: November 2013

Abstract:
Gotha, MS A 688 is currently preserved in the Universitäts- und Forschungsbibliothek Gotha, now kept at the Erfurt University Library in Germany. This is a luxurious manuscript of the neo-Arthurian Ysaïe le Triste: in quarto on paper, copied in a fifteenth- or sixteenth-century bâtarde, and including no fewer than 96 miniatures. The manuscript was probably prepared for Louis II de La Trémouille and his second wife Luisa Borgia, duchesse de Valentinois, both of whose arms are painted on the title page. Prepared perhaps to celebrate their wedding, which took place in 1517, the manuscript must have been produced between 1517 and 1525, Louis having been killed in that year at the battle of Pavia. We have little information on the La Trémouille library, but that said, Louis’s first wife, Gabrielle de Bourbon, was herself an author of several books, and the well-stocked library of Gabrielle’s mother, Gabrielle de La Tour, included copies of Lancelot and Guiron le Courtois.

What is remarkable, however, is the fact that such a lavish manuscript of an Arthurian romance was produced at that time. Not of course that manuscript was obsolete as from the introduction of printing; on the contrary, until much later in the Renaissance, a manuscript, much more than print, represented a very personal gift, for instance, and constituted a prestigious library. That said, only a few Arthurian manuscripts seem to have been produced in sixteenth-century France, let alone manuscripts prepared with such elegance, and of the few that survive, only those produced for the bibliophile Pierre Sala, which he had produced for a modernised Yvain (Paris, BnF MS fr. 1638), and two Tristans (Aberystwyth, National Library of Wales, Add. MS 443-D, and Geneva, Fondation Martin Bodmer, cod. Bodmer 148), all three dating from the 1520s, are of comparable quality. If indeed the Gotha Ysaïe was a gift to Louis and Luisa, it was a lavish gift; we know from a document giving details of expenditures billed by Antoine Vérard for a manuscript printed for Charles of Angoulême, how much such a princely gift might cost. However, the illustrations appear slightly dated: the costumes for example would seem more in the fashion of the mid-fifteenth century. Might our artist have copied an existing suite of miniatures from a manuscript dating from the fifteenth century? Was he simply a provincial artist unfamiliar with the fashions of a new century? These questions are unanswerable – but this manuscript shows, as do the beautiful illustrated manuscrits-imprimés produced for instance by an Antoine Vérard, the prestige enjoyed, even at the heart of the Renaissance, by a beautiful Arthurian manuscript.

Published: November 2013

Abstract
Cultivating positive learning environments for underrepresented groups such as students of Chinese American and Latino backgrounds require careful planning and consideration. As our society strives to embrace individual differences of all cultures, educators must equip themselves with effective tools to adapt to the ever-changing dynamics within classrooms. In an effort to bridge research into practice inside the walls of the school campuses, we discuss recommendations for educators who serve students of Chinese American and Latino backgrounds. The recommended practices are highlighted in layers of society, community, school programming, and classroom experience.
Immigrant-Serving Nonprofits and Philanthropic Foundations
Authors: Brown Heath 
Published: November 2013

AbstractImmigrant-serving nonprofit organizations registered and mobilized thousands of new voters in 2012. These efforts were abetted by philanthropic foundation which, since the early 2000s, have prioritized immigration policy and immigrant issues. Other foundations, hostile to illegal immigration, have funded another set of nonprofits that worked to change immigration policy and voting laws. The article explains these complex relationships between foundations and nonprofits in the context of immigration. The conclusions highlight the tension faced by immigrant-serving nonprofits to maintain their independence and benefit from external funding.
Synthesis and effect of secondary dopant on the conductivity of conducting polymer polyaniline
Authors: Mamma Kedir , Siraj Khalid , Meka Nathan 
Published: November 2013

AbstractPolyaniline (PANI) in its emeraldine salt form was synthesized by chemical method from aniline monomer in the presence of HCl mixed with LiCl and ammonium persulfate as oxidant. Then, a portion of sample was dedoped with NH3solution and another equal portion was separately postdoped with secondary dopants, such as H2SO4and HClO4, respectively. Finally, the dried samples of PANI prepared in all its three different forms (emeraldine salt form, undoped emeraldine base, and the two secondary doped forms of PANI) were characterized by UV-visible spectroscopy, cyclic voltammetry (CV) techniques, Fourier transform infrared (FT-IR) spectroscopy, and electrical conductivity measurement. The cyclic voltammograms of PANI in its emeraldine base (PANI-EB) determined the electrochemical behavior and the growth mechanisms of the polymer. The FT-IR and UV-vis spectra confirmed the expected structural modification up on doping, undoping, and postdoping processes of the polymer. Their measured electrical conductivities were from 0.02 for undoped, 156 for primary doped form, and increasing from 158 to 257 S/cm for those secondary doped PANI. The influence of secondary doping on the electrical conductivity was also investigated from their spectroscopic data which shows dramatic rise in conductivity. The result also shows that secondary doping increased the π conjugation.
Potential utilization of recycled PET in comparison with liquid crystalline polymer as an additive for HDPE based composite fibers: Comparative investigation on mechanical performance of cross-ply laminates

Published: November 2013

Abstract
Recycled polyethylene terephthalate (rPET) was used as an alternative reinforcing material for in situ microfibrillar-reinforced polyethylene (PE) based composite fibers and compared with liquid crystalline polymer (LCP). The neat PE and its composites reinforced with LCP and rPET microfibrils under the compatibilizing promotion of 5 wt% styrene-(ethylene butylene)-styrene-grafted maleic anhydride (SEBS-g-MA) compatibilizer, were prepared as fibers using a hot drawing process. Cross-ply laminates of the neat PE and the compatibilized composite fibers were then prepared using a film stacking method. The tensile, flexural and impact performances of each laminate system were examined and compared. Under tensile loading, no significant differences in the initial part of the stress-strain curves, and hence comparable tensile modulus (≈4 GPa) among all laminates, were observed. A difference was only seen in the final part of the curves. For flexural properties, the flexural moduli of the compatibilized LCP- and rPET-composite laminates were nearly the same (≈3 GPa). At high flexural strains (>1%), the different stress-strain behaviors of the laminates were clearly observed. Interestingly, the compatibilized rPET-composite laminate showed much better impact-resistance compared with PE- and compatibilized LCP-laminates. The results demonstrated a high potential for use of the rPET-composite fiber laminate in impact-resistant applications.
On the use of lock-in thermography to monitor delamination growth in composite panels under compression

Published: November 2013

Abstract
The success of composites in automotive, aerospace, and naval applications is mainly related to their aptitude to be tailored to obtain a final product that perfectly fulfills the design requirements. However, during both manufacturing processes and maintenance, some flaws, like delaminations (which may escape simple visual inspection), may be induced in composite structures. The presence of delaminations is of major concern for the load-carrying capability of carbon fiber-reinforced polymer panels. Indeed, delaminations can strongly affect the structural strength and may grow under in-service loads, leading sometimes to catastrophic failures. The aim of this work is to explore the use of lock-in thermography for the monitoring of delamination propagation in composite structures when subjected to generic multiaxial loading conditions. A stiffened composite panel with an embedded skin delamination subjected to compressive loading was taken as a benchmark to assess experimentally the effectiveness of lock-in thermography for monitoring the delamination propagation in situ during the compressive mechanical test. The delamination size as a function of the applied load, observed by lock-in thermography during the execution of the compressive test, was used to validate the results of preliminary numerical computations.
