Published: March 2010

AbstractObjectiveTo assess the correlation between intratumoral vascularization using three‐dimensional power Doppler angiography (3D‐PDA) and several histological tumor characteristics in a series of patients with endometrial carcinoma.MethodsNinety‐nine women (mean age, 61.7 (range, 31–84) years) diagnosed as having endometrial cancer were assessed by transvaginal 3D‐PDA before surgical staging. Endometrial volume (EV) and 3D‐PDA vascular indices (vascularization index (VI), flow index (FI) and vascularization flow index (VFI)) were calculated using the Virtual Organ Computer‐aided AnaLysis (VOCAL™) method. All patients were surgically staged. Individual tumor features such as histological type, tumor grade, myometrial infiltration depth, lymph‐vascular space involvement, cervical involvement, lymph node metastases and tumor stage were considered for analysis. Multivariate logistic regression (MLR) analysis was used to determine which 3D‐PDA parameters were independently associated with each histological characteristic.ResultsMLR analysis showed that only EV and VI were independently associated with myometrial infiltration (EV: odds ratio (OR), 1.119 (95% CI, 1.025–1.221), P = 0.012; VI: OR, 1.127 (95% CI, 1.063–1.195), P = 0.001) and tumor stage (EV: OR, 1.103 (95% CI, 1.012–1.202), P = 0.025; VI: OR, 1.120 (95% CI, 1.057–1.187), P = 0.001), only VI was independently associated with tumor grade (OR, 1.056 (95% CI, 1.023–1.091), P = 0.001) and only EV was independently associated with lymph node metastases (OR, 1.086 (95% CI, 1.017–1.161), P = 0.001).Conclusion3D‐PDA analysis of tumor vascularization in endometrial cancer correlates with some prognostic histological characteristics.

Single umbilical artery and congenital heart disease in selected and unselected populations
Authors: Prefumo F. , Güven M. A. , Carvalho J. S. 
Published: March 2010

AbstractObjectiveA variable association between single umbilical artery (SUA) and congenital heart disease (CHD) has been reported previously. Discrepancies in the results may be related to the populations studied. In this study we assessed the relationship between SUA and CHD in two well‐defined selected and unselected populations.MethodsThis was a retrospective review of all cases of SUA detected antenatally in a tertiary referral center between 1997 and 2003. Umbilical arteries were routinely identified around the fetal bladder by color‐flow Doppler ultrasonography. The unselected population included pregnancies from a well‐defined geographical area, delivering in the same hospital. The selected group was referred from other hospitals because of suspected abnormalities or other risk factors. Major CHD was defined as CHD needing postnatal treatment or long‐term follow‐up.ResultsThere were 10 fetuses with major CHD in the selected group: four cases among 25 with extracardiac defects (16%; 95% CI, 4.5–36.1%) and six cases out of 22 with no other abnormalities (27%; 95% CI, 10.7–50.2%; P = 0.35). In the unselected group there were two cases of major CHD, both among the 13 fetuses with extracardiac abnormalities (15%; 95% CI, 2–45%), while there were no major cardiac defects in the 85 fetuses with SUA and no extracardiac abnormalities (0%; 95% CI, 0–4%; P = 0.03).ConclusionsThe association between SUA and CHD varies dramatically with population selection criteria. The risk for CHD after the detection of SUA in an otherwise apparently normal fetus from an unselected population seems small and may not warrant specialist fetal echocardiography.

Specific Features of After‐School Program Quality: Associations with Children’s Functioning in Middle Childhood
Authors: Pierce Kim M. , Bolt Daniel M. , Vandell Deborah Lowe 
Published: March 2010

AbstractThis longitudinal study examined associations between three after‐school program quality features (positive staff–child relations, available activities, programming flexibility) and child developmental outcomes (reading and math grades, work habits, and social skills with peers) in Grade 2 and then Grade 3. Participants (n = 120 in Grade 2, n = 91 in Grade 3) attended after‐school programs more than 4 days per week, on average. Controlling for child and family background factors and children’s prior functioning on the developmental outcomes, positive staff–child relations in the programs were positively associated with children’s reading grades in both Grades 2 and 3, and math grades in Grade 2. Positive staff–child relations also were positively associated with social skills in Grade 2, for boys only. The availability of a diverse array of age‐appropriate activities at the programs was positively associated with children’s math grades and classroom work habits in Grade 3. Programming flexibility (child choice of activities) was not associated with child outcomes.

AbstractGaucher disease is caused by a deficiency of the lysosomal enzyme glucocerebrosidase (acid β‐glucosidase), with consequent cellular accumulation of glucosylceramide (GL‐1). The disease is managed by intravenous administrations of recombinant glucocerebrosidase (imiglucerase), although symptomatic patients with mild to moderate type 1 Gaucher disease for whom enzyme replacement therapy (ERT) is not an option may also be treated by substrate reduction therapy (SRT) with miglustat. To determine whether the sequential use of both ERT and SRT may provide additional benefits, we compared the relative pharmacodynamic efficacies of separate and sequential therapies in a murine model of Gaucher disease (D409V/null). As expected, ERT with recombinant glucocerebrosidase was effective in reducing the burden of GL‐1 storage in the liver, spleen, and lung of 3‐month‐old Gaucher mice. SRT using a novel inhibitor of glucosylceramide synthase (Genz‐112638) was also effective, albeit to a lesser degree than ERT. Animals administered recombinant glucocerebrosidase and then Genz‐112638 showed the lowest levels of GL‐1 in all the visceral organs and a reduced number of Gaucher cells in the liver. This was likely because the additional deployment of SRT following enzyme therapy slowed the rate of reaccumulation of GL‐1 in the affected organs. Hence, in patients whose disease has been stabilized by intravenously administered recombinant glucocerebrosidase, orally administered SRT with Genz‐112638 could potentially be used as a convenient maintenance therapy. In patients naïve to treatment, ERT followed by SRT could potentially accelerate clearance of the offending substrate.
Life as a Pregnant Genetic Counselor
Authors: Clark Kit 
Published: March 2010

AbstractPregnancy is a life‐changing experience that many, if not most, women will experience during their lives. Though exciting, it can present challenges, both physical and psychological. Those challenges may be amplified when working in a prenatal setting. Here, one genetic counselor discusses her experiences, and the lessons she learned, as a new counselor trying to learn the ropes while simultaneously navigating the unfamiliar territory of her pregnancy.
Effect of Surfactants as Dispersing Agents on the Properties of Microemulsified Inkjet Inks for Polyester Fibers
Authors: Kosolia Chrysavgi Th. , Varka Evi Maria , Tsatsaroni Eforia G. 
Published: March 2010

AbstractThe preparation of microemulsified disperse inkjet inks was carried out and the effect of the surfactant used as dispersing agents on the properties of the inks was studied. The dispersing agents used were anionic conventional and non‐conventional surfactants and a gemini type surfactant. The properties studied were surface tension, pH, conductivity, viscosity and the particle size distribution. The use of the gemini type and the two non conventional surfactants even in submultiple amounts resulted in a significant increase in the ink stability.
Popularity and Vote: Forecasting the 2007 French Presidential Election
Authors: Auberger Antoine 
Published: March 2010

Abstract. The purpose of this article is to build a model that explains and forecasts the outcome of the second-round vote in the French presidential elections (with the hypothesis of a classic duel between left and right) in each department and at the national level. This model highlights the influence of the popularity of the Socialist party and a partisan variable in the explanation of the second-round vote for the candidate of the left in the French presidential elections. Its forecasts for the elections of the past (1981–1995 and 1981–2007, excluding 2002) are satisfactory and we make ex ante forecasts for the 2007 French presidential election.Résumé. L'objet de cet article est de construire un modèle qui explique et prévoit le résultat du second tour de scrutin aux élections présidentielles françaises (en supposant le duel classique entre la gauche et la droite) dans chaque département et au niveau national. Ce modèle met en lumière l'influence de la popularité du Parti socialiste et d'une variable partisane dans l'explication du vote au second tour pour le candidat de la gauche aux élections présidentielles. Les prévisions ex post pour les élections passées (de 1981 à 1995 et de 1981 à 2007, en excluant 2002) sont satisfaisantes et on établit des prévisions ex ante pour l'élection présidentielle française de 2007.
Quelle est la spécificité des discours électoraux? Le cas de Stephen Harper
Authors: Labbé Dominique , Monière Denis 
Published: March 2010

Résumé. Cette étude de cas démontre que le discours électoral possède des caractéristiques propres. On donne l'exemple de Stephen Harper dont les discours tenus lors des élections de 2008 se différencient de ceux qu'il a prononcés à titre de chef de gouvernement. Le discours électoral est plus ancré socialement. C'est aussi un discours qui valorise le collectif national; le locuteur privilégie l'emploi du «nous», plutôt que de se présenter comme principal responsable des choix collectifs. Comparativement aux discours gouvernementaux, le discours électoral est aussi moins abstrait et plus orienté vers l'action, comme l'indique la prédominance du groupe verbal sur le groupe nominal. La forte présence de la construction négative et la désignation des adversaires (noms propres) soulignent le caractère polémique du discours électoral.Abstract. This case study demonstrates that electoral speeches possess specific characteristics. We give the example of Stephen Harper's speeches, given during the 2008 elections, which differ from those delivered when he was prime minister. The electoral speech is more socially anchored. It values the nation. When he is campaigning, S. Harper also uses the pronoun “we” more frequently, so that he does not appear as the main decider of collective choices. Compared with governmental speeches, electoral speeches are also less theoretical and more action orientated as indicated by the predominance of verbal over nominal groups. The very frequent presence of the negative construction and the use of opponents' names highlight the polemic character of electoral speeches.
PHOTOPERIOD EFFECTS ON FLOWERING AND SEED SETTING OFHYPERICUM PERFORATUM

Published: March 2010

SUMMARYThe effects of day length extension and night interruption on flowering responses of St John's Wort (Hypericum perforatum) plants were investigated. Field-grown plants were subjected to five different day lengths (11, 13, 15, 17 and 19 h d−1) or night interruption for 70 days. The results indicated that St John's Wort is a long-day plant requiring a critical day length of 15 hd−1for flowering induction. Both day length extension (duration longer than 15 h) and night interruption, with artificial light (fluorescent lamps that delivered 30 μmol m−2s−1photosynthetic photon flux density at plant height) were effective for flowering induction and seed setting. Day length extension or night interruption experienced by the maternal plant also affected the germination responses of the seeds produced. Plants that had received 19 h of day length treatment produced seeds with better germination responses. Night interruption with daylight type fluorescent lamps was also effective for producing relatively high quality seeds, although these seeds had slightly lower germination rates and longer mean germination time than seeds produced under 19 h of day length. Such a night interruption system could be considered for seed production of St John's Wort on a commercial scale.

Italian musicians, both young and old, have been notably active during the war period. Until the Spring of 1943–the eve of disaster—there were many outstanding performances of theatrical and symphonic compositions.As a result of the blackout and the increase in aerial warfare, the theatres presented their performances during the day, but the concert halls continued their activities as usual—albeit the performances were often interrupted by the sound of the air-raid siren.
Optimal balancing of robot manipulators in point-to-point motion
Authors: Nikoobin A. , Moradi M. 
Published: March 2010

SUMMARYIn this paper, a new balancing approach called “optimal balancing” is presented for open-chain robot manipulators based on open-loop optimal control. In fact, an optimal trajectory planning problem is outlined in which states, controls and the values of counterweights must be determined simultaneously in order to minimize the given performance index for a predefined point-to-point task. Optimal balancing method can be propounded beside the other methods such as unbalancing, static balancing and adaptive balancing, with this superiority that the objective criterion value obtained of proposed method is very lower than the objective criterion value obtained of other methods. For this purpose, the optimal control problem is extended to the case where the performance index, the differential constraints and the prescribed final conditions contain parameters. Using the fundamental theorem of calculus of variations, the necessary conditions for optimality are derived which lead to the optimality conditions associated with the Pontryagin's minimum principle and an additional condition associated with the constant parameters. By developing the obtained optimality conditions for the two-link manipulator, a two-point boundary value problem is achieved which can be solved with bvp4c command in MATLAB®. The obtained results show that optimal balancing in comparison with the previous methods can reduce the performance index significantly. This method can be easily applied to the more complicated manipulator such as a three degrees of freedom articulated manipulator.
An equivalence between inverse sumset theorems and inverse conjectures for theU3norm
Authors: GREEN BEN , TAO TERENCE 
Published: March 2010

AbstractWe establish a correspondence betweeninverse sumset theorems(which can be viewed as classifications of approximate (abelian) groups) andinverse theorems for the Gowers norms(which can be viewed as classifications of approximate polynomials). In particular, we show that the inverse sumset theorems of Freĭman type are equivalent to the known inverse results for the GowersU3norms, and moreover that the conjectured polynomial strengthening of the former is also equivalent to the polynomial strengthening of the latter. We establish this equivalence in two model settings, namely that of the finite field vector spaces2n, and of the cyclic groups ℤ/Nℤ.In both cases the argument involves clarifying the structure of certain types ofapproximate homomorphism.

Published: March 2010

AbstractDuring the summer 2005/06, an oceanographic cruise was carried out in the Ross Sea, from Cape Adare, through the Terra Nova Bay polynya to the eastern edge of the Ross Ice Shelf. We analysed microbial activities (prokaryotic carbon production, protease, phosphatase, beta-glucosidase and lipase activity) and bacterial community structure (using Denaturing Gradient Gel Electrophoresis - DGGE) in order to establish if differences in bacterioplankton assemblages and their metabolic requirements occur within the five Ross Sea water masses: Antarctic Surface Waters (AASW), High Salinity Shelf Water (HSSW), Ice Shelf Water (ISW), Antarctic Bottom Water (AABW), Circumpolar Deep Water (CDW). Differences in activities were found between the highly active AASW and all the other water bodies. A Principal Component Analysis highlighted two main gradients: in the Cape Adare area (AASWn, CDW and AABW) higher phosphatase, lipase and glycolytic activities, increasing towards the surface, were identified, whereas in the southern sector of the basin [AASWs and (m)HSSW] higher leucine uptake and polypeptide degradation characterized the second gradient. DGGE fingerprinting showed for the first time that different water masses harboured diverse bacterial communities, highlighting the high specificity of deep water assemblages.Alpha- andGammaproteobacteriarepresented the main phylogenetic groupings in all samples and no substantial difference in the phylogenetic composition of assemblages was found between different water masses.
Malonaldehyde formation and DNA fragmentation: two independent sperm decays linked to reactive oxygen species

Published: March 2010

SummaryMalondialdehyde (MDA), a product involved in membrane lipid peroxidation, was dosed in the sperm of 163 patients who had consulted the clinic regarding hypofertility. We attempted to determine if there was correlation between MDA content, sperm World Health Organization parameters and DNA fragmentation that results mainly from reactive oxygen species assaults. We found that no correlation could be established; however MDA and sperm decondensation were shown to be significantly linked. The impact of membrane polyunsaturated fatty acids and the role of phospholipid hydroperoxide glutathione peroxidase are discussed.
Automatic summarisation of discussion fora

Published: March 2010

AbstractWeb-based discussion fora proliferate on the Internet. These fora consist of threads about specific matters. Existing forum search facilities provide an easy way for finding threads of interest. However, understanding the content of threads is not always trivial. This problem becomes more pressing as threads become longer. It frustrates users that are looking for specific information and also makes it more difficult to make valuable contributions to a discussion. We postulate that having a concise summary of a thread would greatly help forum users. But, how would we best create such summaries? In this paper, we present an automated method of summarising threads in discussion fora. Compared with summarisation of unstructured texts and spoken dialogues, the structural characteristics of threads give important advantages. We studied how to best exploit these characteristics. Messages in threads contain both explicit and implicit references to each other and are structured. Therefore, we term the threadshierarchical dialogues. Our proposed summarisation algorithm produces one summary of an hierarchical dialogue by ‘cherry-picking’ sentences out of the original messages that make up a thread. We try to select sentences usable for obtaining an overview of the discussion. Our method is built around a set of heuristics based on observations of real fora discussions. The data used for this research was in Dutch, but the developed method equally applies to other languages. We evaluated our approach using a prototype. Users judged our summariser as very useful, half of them indicating they would use it regularly or always when visiting fora.

Published: March 2010

AbstractThe aim of this study was to shed light on the nature of the imagery deficits in two patients with representational neglect and to determine whether representational neglect is affected by the content of the mental images the patients have to generate, inspect and manipulate. In particular, we submitted two patients with different types of representational neglect to a battery of visual mental imagery tests to assess the different kinds of imagery processes. We found that Patient 1,whose performance was asymmetrical on the O’Clock Test, performed poorly on tasks involving the mental generation, inspection and manipulation of objects but showed no deficit on tasks involving the mental generation, inspection and manipulation of environments. On the other hand, Patient 2, whose performance was asymmetrical on the Familiar Squares Description Test, performed poorly on tasks involving the mental generation, inspection and manipulation of environments, but not on tasks involving the mental generation, inspection and manipulation of objects. Our results demonstrate that environments and objects in the imagery domain can be represented separately and can be selectively affected by damage following brain lesions. (JINS, 2010,16, 921–932.)
Twisted geometric Satake equivalence
Authors: Finkelberg Michael , Lysenko Sergey 
Published: March 2010

AbstractLet k be an algebraically closed field and O = k[[t]] ⊂ F = k((t)). For an almost simple algebraic group G we classify central extensions 1 → $\mathbb{G}_m\to E\to G(\bm{F})\$m → E → G(F) → 1; any such extension splits canonically over G(O). Fix a positive integer N and a primitive character ζ : μN(K) →$\mathbb{Q}}_\ell^*}$ (under some assumption on the characteristic of k). Consider the category of G(O)-bi-invariant perverse sheaves on E with $\mathbb{G}_m$m-monodromy ζ. We show that this is a tensor category, which is tensor equivalent to the category of representations of a reductive group ǦE,N. We compute the root datum of ǦE,N.
Decomposing CO2 emissions data into a pair of logistic growth pulses
Authors: Alexandrov Gleb 
Published: March 2010

AbstractNumerous scenarios of emissions growth presume that it can not grow infinitely: there are certain limits that may not or must not be exceeded. Applying the theory of pulsing logistic growth, I detected two pulses of logistic growth. This led me to the conclusion that constructing a scenario of emissions growth one should pay attention to the fact that limits to their growth do not remain constant.
