Abstract:
Accurate and rapid defect identification based on pulsed eddy current testing (PECT) plays an important role in the structural integrity and health monitoring (SIHM) of in-service equipment in the renewable energy system. However, in conventional data-driven defect identification methods, the signal feature extraction is time consuming and requires expert experience. To avoid the difficulty of manual feature extraction and overcome the shortcomings of the classic deep convolutional network (DCNN), such as large memory and high computational cost, an intelligent defect recognition pipeline based on the general Warblet transform (GWT) method and optimized two-dimensional (2-D) DCNN is proposed. The GWT method is used to convert the one-dimensional (1-D) PECT signal to a 2D grayscale image used as the input of 2D DCNN. A compound method is proposed to optimize the baseline VGG16, a well-known DCNN, from four aspects including reducing the input size, adding batch normalization layer (BN) after every convolutional layer(Conv) and fully connection layer (FC), simplifying the FCs, and removing unimportant filters in Convs so as to reduce memory and computational costs while improving accuracy. Through a pulsed eddy current testing (PECT) experiment considering interference factors including liftoff and noise, the following conclusion can be obtained. The time-frequency representation (TFR) obtained by the GWT method not only has excellent ability in terms of the transient component analysis but also is less affected by the reduction of image size; the proposed optimized DCNN can accurately identify defect types without manual feature extraction. And compared to the baseline VGG16, the accuracy obtained by the optimized DCNN is improved by 7%, to about 99.58%, and the memory and computational cost are reduced by 98%. Moreover, compared with other well-known DCNNs, such as GoogLeNet, Inception V3, ResNet50, and AlexNet, the optimized network has significant advantages in terms of accuracy and computational cost, too.

J. Plant Sci. 93: 1125–1142. Most plants host endophytic bacteria, but their identities and functions are usually unknown. Bacterial endophytes associated with potato grown after dry bean (Phaseolus vulgaris L.) or wheat (Triticum aestivum L.) were isolated, quantified and identified in a field study that compared crop rotations (3 to 6 yr in length) and soil management (CONV, conventional; CONS, conservation) for dry bean, potato, sugar beet (Beta vulgaris L.) and spring wheat. Populations of culturable endophytes ranged from 2.83×103 to 7.65×103 colony-forming units g−1 of root dry matter. The populations and diversity of the endophytes were greater with CONS than CONV soil management, and tended to be greater in longer than shorter rotations. The community structures of the endophytes were different between CONV and CONS soil management. A terminal-restriction fragment length polymorphism assay targeting the 16S rRNA gene, and its sequencing, showed that CONS management systems contained more Proteobacteria than CONV management systems, and vice-versa for Acidobacteria. Bacteriodetes were found only in long CONS rotations. This phylogenetic characterization of potato endophytes is important for further studies on their effects on the host plants.

Abstract:
Sugar beet (Beta vulgaris L.) has a long history as an option for irrigated crop rotations in southern Alberta. A 12-yr (2000–2011) study compared conservation (CONS) and conventional (CONV) management for sugar beet in 4- to 6-yr rotations which also included dry bean (Phaseolus vulgaris L.), potato (Solanum tuberosum L.), and soft white spring wheat (Triticum aestivum L.). Oat (Avena sativa L.) and timothy (Phleum pratense L.) were included in the longest 6-yr rotation. Conservation management incorporated reduced tillage, cover crops, feedlot manure compost addition, and solid-seeded dry bean. Compared with a 4-yr CONV rotation (52.2 Mg ha−1), sugar beet root yield (averaged over the second 6 yr of the study, 2006–2011) was significantly higher, by 11%, on 4- and 5-yr CONS rotations (57.7–57.9 Mg ha−1), and by 8% on a 6-yr CONS rotation (56.1 Mg ha−1). Sugar beet impurity parameters were significantly affected by rotation in, at most, 3 of 12 yr. However, averaged over the final 6 yr of the study (2006–2011), a significantly higher K concentration (impurity) was found with CONS (2108 mg kg−1) vs. CONV (1958 mg kg−1) management. Integrating CONS management practices into sugar beet rotations led to significant yield benefits while effects on sugar beet quality were minimal.

Abstract:
Knowledge graph embedding has been an active research topic for knowledge base completion, with progressive improvement from the initial TransE, TransH, DistMult et al to the current state-of-the-art ConvE. ConvE uses 2D convolution over embeddings and multiple layers of nonlinear features to model knowledge graphs. The model can be efficiently trained and scalable to large knowledge graphs. However, there is no structure enforcement in the embedding space of ConvE. The recent graph convolutional network (GCN) provides another way of learning graph node embedding by successfully utilizing graph connectivity structure. In this work, we propose a novel end-to-end StructureAware Convolutional Network (SACN) that takes the benefit of GCN and ConvE together. SACN consists of an encoder of a weighted graph convolutional network (WGCN), and a decoder of a convolutional network called Conv-TransE. WGCN utilizes knowledge graph node structure, node attributes and edge relation types. It has learnable weights that adapt the amount of information from neighbors used in local aggregation, leading to more accurate embeddings of graph nodes. Node attributes in the graph are represented as additional nodes in the WGCN. The decoder Conv-TransE enables the state-of-the-art ConvE to be translational between entities and relations while keeps the same link prediction performance as ConvE. We demonstrate the effectiveness of the proposed SACN on standard FB15k-237 and WN18RR datasets, and it gives about 10% relative improvement over the state-of-theart ConvE in terms of HITS@1, HITS@3 and HITS@10.

Abstract:
The duration of spermatic viability in the female reproductive system in cattle is 18 to 24 hours. Therefore, the time required for sperm capacitation in different bulls demonstrated to be highly variable and may affect the adequate amount of capacitated sperm within an optimal window of time for fertilization. The aim of this study was to evaluate the conception rate in Nelore cows inseminated with semen from a single bull compared with semen from a pool of 3 bulls (Fertility Plus®, ABS Pecplan, Minas Gerais, Brazil). On a random day of the estrous cycle (Day 0), 400 Nelore multiparous cows received a progesterone intravaginal device (1 g of P4, DIB®, Intervet/Schering-Plough, Cotia, Brazil) plus 2mg of estradiol benzoate (i.m. Estrogin®, Farmavet, São Paulo, Brazil). At the time of P4 device withdrawal (Day 8), 150 (ig of d-cloprostenol (i.m. Preloban®, Intervet/Schering-Plough), 1 mg of estradiol cypionate (i.m. ECP®, Pfizer, Brazil), and 300IU of eCG (i.m. Folligon®, Intervet/Schering-Plough) were administered. At 48 to 52 h after implant removal, all cows were fixed-time inseminated (FTAI). Then, cows were homogeneously distributed based on the semen used for FTAI in 4 groups: CONV1 (conventional dose of semen from bull 1), CONV2 (conventional dose of semen from bull 2), CONV3 (conventional dose of semen from bull 3), FERT (pool of semen from bulls 1, 2 and 3 homogeneously mixed in a single dose). Both conventional and Fertility Plus batches of semen contained a total dose of 30 × 106 spermatozoa. For pregnancy diagnosis, an ultrasonographic (CHISON 500VET, USP Brasil Eletromedicina, São Paulo, Brazil) examination was performed 30 days after the FTAI. Data were analyzed using the GENMOD procedure of SAS (SAS Institute, Cary, NC, USA). There was no interaction between treatment and body condition score [using a 1 (very thin) to 5 (very fat) point scale] or AI technician. The conception rates for CONV1, CONV2, CONV3, and FERT were, respectively, 40/101 (39.6%)b, 50/99 (50.5%)ab, 46/99 (46.5%)ab, 54/101 (53.5%)a; P < 0.05. In addition, the mean of conventional v. Fertility Plus treatments presented conception rates of 136/299 (45.5%) v. 54/101 (53.5%), respectively (P = 0.14). No significant statistical differences were observed between treatments. However, this trial showed that the utilization of the new Fertility Plus technology increased the overall conception rate by 8.0%. This probably implicates a complementary effect among semen samples and provides a greater time of sperm viability in oviduct. Also it provides evidence of the individual variation in capacitation time of bulls used for composition of the pool. Pooled semen of multiple sires may improve the reproductive performance at AI in cattle and increase the potential of the beef industry to produce pregnancies and born calves.

Abstract:
A manutenção das funções do solo nos agroecossistemas encontra-se entre os principais desafios da comunidade científica, na atualidade. Assim, este estudo objetivou avaliar indicadores físicos, químicos e biológicos de qualidade do solo, em três unidades de produção comercial de morango, em Brazlândia (DF), sendo duas sob sistema de produção convencional (Conv1 e Conv2) e uma sob sistema orgânico (Org). O Conv1 é caracterizado pelo cultivo de morango em área que esteve ocupada por 12 anos com pastagem (Brachiaria spp.), sem controle de lotação e sem adubação; o Conv2 pelo cultivo do morango em sucessão/rotação com outras espécies olerícolas; e o Org ocorreu após a adubação verde com o consórcio de milho e mamona. Os atributos indicadores de qualidade do solo avaliados foram: densidade de solo, estabilidade de agregados, matéria orgânica, capacidade de troca catiônica (CTC), condutividade elétrica, β-glicosidase e fosfatase ácida. Os valores observados para os indicadores físicos foram, de maneira geral, considerados sustentáveis, para latossolos do Cerrado. Os teores de matéria orgânica mostraram-se similares em todos os sistemas e a CTC foi superior ou próxima ao limite crítico considerado sustentável. Em função da elevada aplicação de fertilizantes, a maior condutividade elétrica foi registrada para o Conv2, mas não houve efeito deletério sobre a produtividade. As atividades das enzimas β-glicosidase e fosfatase ácida indicaram boa qualidade biológica do solo, em todas as unidades produtivas de morango avaliadas.

Plant growth-promoting and phytopathogen-antagonistic properties of bacterial endophytes from potato (Solanum tuberosum L.) cropping systems. Can. J. Plant Sci. 94: 835–844. Endophytes are microorganisms that live within a plant without harming it. Bacterial endophytes were isolated from roots of potatoes (Solanum tuberosum L.) grown under different rotations (3 to 6 yr in length) and soil management (CONV, conventional; CONS, conservation) in irrigated cropping systems with dry bean (Phaseolus vulgaris L.), sugar beet (Beta vulgaris L.) spring wheat (Triticum aestivum L.) and timothy (Phleum pratense L.). The endophytes were characterized for nitrogen fixation potential, phytohormone production and phytopathogen-antagonistic properties. The nitrogen-fixing nitrogenase (nifH) gene was detected in potato grown in all rotations, presumably partly because the soil in all rotations contained Rhizobium leguminosarum bv. phaseoli from the dry bean phase. Sequence analysis revealed that it was homologous to the genes found in Burkholderia, Azospirillum, Ideonella, Pseudacidovorax and Bradyrhizobium species. Indole acetic acid (IAA) hormone production by endophytes isolated from potato grown under CONS management was 66% greater than that those isolated from potato grown under CONV management, and tended to be greater in longer than shorter rotations. When 12 endophytes were inoculated to dry bean, four increased shoot biomass by 27–34%, and six increased total (shoot+root) biomass by 25% on average. Endophytes from the longer CONS rotations (4–6 yr) resulted in significantly higher (by 9%) shoot biomass than the shortest CONS (3 yr) rotation. Six of 108 endophyte isolates exhibited antagonistic properties (reduced pathogen biomass by 12 to 58% in dual culture assays in liquid media) against potato pathogens Pectobacterium atrosepticum, Fusarium sambucinum and Clavibacter michiganensis subsp. epedonicus. All the six isolates were from CONS soil management. Therefore, the benefits of long rotations, with their associated CONS soil management, to crop productivity in these irrigated cropping systems probably include nutritional (biological nitrogen fixation and IAA hormone production) and disease-control benefits imparted by endophytic bacteria.

Abstract:
Object The goal of this study was to compare long-term results of surgery with the outcomes of conservative treatment in patients with asymptomatic lipomas of the conus medullaris. Methods The parents of 56 consecutive children with a diagnosis of asymptomatic lipoma of the conus medullaris underwent detailed neurosurgical consultation. The pros and cons of both prophylactic surgery and conservative treatment were carefully presented. Both options were offered, and the parents were free to choose the preferred management. A total of 32 children underwent surgical treatment, and 24 were conservatively treated. Afterward, all patients entered the same protocol of serial neurological and urological follow-up at the Centro Spina Bifida. The mean follow-up periods were 9.7 years in the surgical treatment group and 10.4 years in the conservative treatment group. Results Permanent surgical morbidity was 3.1% (1 patient). During follow-up, tethered cord syndrome occurred in 9.7% of the surgically treated patients (3 of 32 patients) and in 29.1% of the conservatively managed children (7 of 24 patients). This difference did not result in statistical significance, but a clear trend in favor of surgery emerged. Young age at surgery and a cord/sac ratio < 50% appeared to be determining factors in the prevention of subsequent tethered cord syndrome. Conclusions The small size of this series does not provide enough statistical evidence that surgical treatment can really improve the natural history of asymptomatic lipomas of the conus medullaris. Nevertheless, surgery appears at least advisable since it reduces by 75% the odds of TCS (p = 0.067), which is quite close to statistical significance.

Abstract:
La lavande et le lavandin sont des plantes à parfums très appréciées des industries cosmétiques et de la parfumerie, et sont un des symboles de la Provence. Seulement, les lavanderaies françaises subissent un fort déclin depuis une quinzaine d’années lié à des épisodes de sécheresse et à une maladie communément appelée « le dépérissement de la lavande ». Cette maladie est provoquée par une bactérie sans paroi le phytoplasme du Stolbur (Candidatus Phytoplasma solani) et véhiculée par un insecte la cicadelle (Hyalestes obsoletus). Cette thèse se propose d’étudier les interactions tripartites entre l’insecte, la plante et la bactérie à travers les modifications induites sur les composés organiques non volatiles (COnVs).Pour répondre à cette problématique, une approche métabolomique non ciblée a été développée et réalisée sur quatre variétés de lavande (7713, maillette) et de lavandin (abrial, grosso). Pour ce faire, une campagne d’échantillonnage a été menée en champs et a conduit au prélèvement de 480 échantillons. Des triplicats d’extraction ont ensuite été réalisés par extraction solide-liquide assistée par ultra-sons avec un mélange eau-éthanol (50:50, v/v). Les analyses ont été conduites sur une UPLC-HRMS (XevoG2 QTOF, Waters). Le traitement des données a été effectué sur la plateforme W4M-Galaxy pour l’extraction des données spectrales, et sur MetaboAnalyst pour les corrections et les tests statistiques (ACP et PLS-DA). Les résultats obtenus ont mis en évidence des différences significatives entre des variétés sensibles et tolérantes au phytoplasme du Stolbur pour chaque organe étudié (parties chlorophylliennes / inflorescences). Des signatures chimiques distinctes en fonction de l’état symptomatique des plants (symptomatique/asymptomatique) ont également pu être révélées pour plusieurs variétés et parties de la plante. En fonction des organes, des composés discriminants du caractère symptomatique communs à plusieurs variétés ont été détectés. Plusieurs dérivées de chlorophylles et des caroténoïdes ont été trouvés comme probables marqueurs de l’état sanitaires des plantes<br>Fine lavender and lavandin are historic and emblematic crops of Provence (South-East France). They are cultivated for their aromatic and perfume properties. They represented an important economic value in France. Nevertheless, over the last decades, lavender’s field decline because of the lack of rain fall and a disease name “yellow disease”. This infection lead to phloem-limited bacterial pathogen (Candidatus Phytoplasma solani) and transmitted by a planthopper (Hyalesthes obsoletus). The purpose of this PhD is to study induced chemical defences (i.e. non-volatile organic compounds) in order to better understand interaction between insect, plant and bacteria. To answer this issue, an untargeted metabolomic approach was developed. Four varieties chosen for their sensibility or tolerance against phytoplasma, were used: two lavender (7713, maillette) and two lavandin (abrial, grosso), and 480 samples were collected. Compound extraction was performed by a solid-liquid extraction assisted by ultrasounds with an ethanol-water mixture (50:50, v/v). Afterwards, 1429 extracts were analysed by an UPLC-HRMS (XevoG2 QTOF, Waters). Spectral data was first handle using W4M-Galaxy to obtain a peak table fitting by statistical tools. Next, MetaboAnalyst was conducted to correct data and performed multivariate analyses. PCA was used to visualize trends and outliers. PLS-DA was applied to highlight biological differences between subgroups, to discover the most relevant factors and detected biomarkers. The most discriminant compounds specific to sensitivity/tolerant species as well as to plant symptomatic status (asymptomatic/symptomatic) were annotated. Chlorophyll derivatives, under-expressed in symptomatic plants, are probably health plant status biomarkers

Abstract:
Alluvial fans, debris cones and rockfall talus cones are widespread in upland Britain, but remarkably little is known about their characteristics, development and significance. This research project has three main objectives: 1. to establish the morphological and surface sedimentary characteristics of alluvial fans, debris cones and talus cones in the Grampian Highlands of Scotland; 2. to identify the factors that have controlled their formation and distribution; and 3. to determine the timing, nature and rate of fan- and cone-forming processes. On the basis of previous literature, an Orioni model that describes a continuum of fan and cone morphological and surface sedimentary properties was devised. The applicability of this model was tested using data for six variables (long profile gradient, slope form, downslope changes in clast size, roundness and form, and a scale ratio of maximum clast size to total fan or cone length) obtained for fans and cones in the Grampian Highlands and the Lyngen Peninsula in Northern Norway. The results of these tests were then used to produce a modified model appropriate to fans and cones in upland Britain. Using a combination of map, field and aerial photograph data, several environmental and morphometric controls on the distribution and type of fan and cone development were investigated. The dimensions of different types of fan and cone are shown to be determined by basin morphometry, lithology and glacial history. Discriminant analysis identified basin gradient, basin width and basin height as the principal catchment properties that influence the dominant type of fan- or cone-forming process. Stratigraphic and radiocarbon evidence suggests that many debris cones are essentially paraglacial landforms that formed in the earlier part of the Flandrian. Many of these cones have subsequently been modified in the late Flandrian by fluvial processes, in some cases in response to anthropogenic interference. However, evidence from one site has also revealed that substantial debris cone aggradation has occurred since c 300 BP, implying high rates of denudation in the recent past at this site. The volumes of other debris cones imply that as much as 1-3m of surface lowering has occurred in gullies upslope since deglaciation. Much lower values of surface lowering are associated with alluvial fan development, suggesting that, locally at least, denudation by fluvial processes has been less significant than denudation resulting from debris flow.

Abstract:
Cette thèse se consacre à la mise au point de techniques d’échantillonnage suivies d’analyses réalisées au laboratoire pour mettre en évidence les espèces majoritaires en air intérieur et caractériser leurs variations temporelles. Le développement analytique a été effectué pour 52 COVs et pour 16 HAPs associés à la phase particulaire de l’air. Les prélèvements des COVs ont été réalisés au moyen d’un préleveur automatique permettant d’échantillonner l’air sur des tubes extraits par désorption thermique et analysés par chromatographie gazeuse couplée à la détection FID. Pour la quantification des HAPs, le prélèvement des particules est effectué par un impacteur à cascade à trois étages permettant de fractionner l’aérosol en fonction de leur diamètre aérodynamique. Les HAPs sont quantifiés par chromatographie liquide haute performance couplée à la détection par fluorescence. Ces deux techniques ont été mises en application dans le cadre de la 1ère campagne intensive du projet MERMAID<br>This work aims at developing rapid and simple air sampling techniques followed by laboratory analyses to highlight the occurrence of the main species in indoor air and to describe their temporal variations. The analytical development was focused on 52 VOCs belonging to a wide variety of chemical families to determine their concentrations. The sampling step was performed using an automatic sampler allowing the sampling of air on adsorbent tubes. These tubes were then thermally desorbed and analyzed by gas chromatography coupled to FID. Another analytical development was conducted to determine the particle bound PAHs concentrations. The sampling of particles was realized by the mean of a 3-stages cascade impactor allowing an aerosol fractionation depending on their aerodynamic diameter. Finally, quantification of PAHs was realized by liquid chromatography coupled to fluorescence detection. These two techniques were applied in a field campaign in the frame of the MERMAID program

Abstract:
In this dissertation we study the algebraic properties of the intersection algebra of two ideals I and J in a Noetherian ring R. A major part of the dissertation is devoted to the finite generation of these algebras and developing methods of obtaining their generators when the algebra is finitely generated. We prove that the intersection algebra is a finitely generated R-algebra when R is a Unique Factorization Domain and the two ideals are principal, and use fans of cones to find the algebra generators. This is done in Chapter 2, which concludes with introducing a new class of algebras called fan algebras. Chapter 3 deals with the intersection algebra of principal monomial ideals in a polynomial ring, where the theory of semigroup rings and toric ideals can be used. A detailed investigation of the intersection algebra of the polynomial ring in one variable is obtained. The intersection algebra in this case is connected to semigroup rings associated to systems of linear diophantine equations with integer coefficients, introduced by Stanley. In Chapter 4, we present a method for obtaining the generators of the intersection algebra for arbitrary monomial ideals in the polynomial ring.
