Méthodes rapides de traitement d’images hyperspectrales. Application à la caractérisation en temps réel du matériau bois

Cette these aborde le demelange en-ligne d’images hyperspectrales acquises par un imageur pushbroom, pour la caracterisation en temps reel du materiau bois. La premiere partie de cette these propose un modele de melange en-ligne fonde sur la factorisation en matrices non-negatives. A partir de ce modele, trois algorithmes pour le demelange sequentiel en-ligne, fondes respectivement sur les regles de mise a jour multiplicatives, le gradient optimal de Nesterov et l’optimisation ADMM (Alternating Direction Method of Multipliers) sont developpes. Ces algorithmes sont specialement concus pour realiser le demelange en temps reel, au rythme d'acquisition de l'imageur pushbroom. Afin de regulariser le probleme d’estimation (generalement mal pose), deux sortes de contraintes sur les endmembers sont utilisees : une contrainte de dispersion minimale ainsi qu’une contrainte de volume minimal. Une methode pour l’estimation automatique du parametre de regularisation est egalement proposee, en reformulant le probleme de demelange hyperspectral en-ligne comme un probleme d’optimisation bi-objectif. Dans la seconde partie de cette these, nous proposons une approche permettant de gerer la variation du nombre de sources, i.e. le rang de la decomposition, au cours du traitement. Les algorithmes en-ligne prealablement developpes sont ainsi modifies, en introduisant une etape d’apprentissage d’une bibliotheque hyperspectrale, ainsi que des penalites de parcimonie permettant de selectionner uniquement les sources actives. Enfin, la troisieme partie de ces travaux consiste en l’application de nos approches a la detection et a la classification des singularites du materiau bois.
Patterns and prediction of behavior problems during the toddler and preschool periods in preterm children

There are few studies of behavior problems in preterm children prior to 2 years old and the changes that occur over time. The aims of this study were to examine the patterns and prediction of behavior problems and the effects of gender and socioeconomic status (SES) on behavior problems in preterm children at the toddler and preschool periods. Parents of 124 very low birthweight preterm children completed a standardized behavior questionnaire at 18 months corrected age and 3 years old. At both times, scores were significantly higher on Attention and Withdrawn Problems than on other behavior problem syndromes. There was a significant overall increase in Externalizing and Internalizing behavior problem scores between 18 months and 3 years, particularly in Internalizing problems. Overall prediction for normal versus not-normal categorization (≥1 standard deviation) on behavior problem and broad-spectrum scales ranged from 77% to 90% and was higher for children in the normal than not-normal categories. Boys had higher Internalizing Problems at 18 months and higher Externalizing Problems at 3 years. Children from low SES families had higher Internalizing and Total Behavior problems at 18 months and higher Internalizing, Externalizing, and Total Behavior problems at 3 years. Screening preterm children for behavior problems before 2 years old appears useful for early intervention of such problems.

Guidance on tiered risk assessment for plant protection products for aquatic organisms in edge-of-field surface waters

EFSA‘s Panel on Plant Protection Products and their Residues (PPR) was tasked to revise the Guidance Document (GD) on Aquatic Ecotoxicology under Council Directive 91/414/EEC (SANCO/3268/2001 rev.4 (final), 17 October 2002). This Guidance of the PPR Panel is the first of three requested deliverables within this mandate. It has its focus on tiered acute and chronic effect assessment schemes with detailed guidance on tier 1 and higher tier effect assessments for aquatic organisms in edge-of-field surface waters and on proposals regarding how to link effects to exposure estimates. The exposure assessment methodology was not reviewed and it is assumed that the current FOCUS surface water exposure assessment methodology will continue to be used for exposure assessment at EU level. The current GD is intended to be used for authorisation of active substances at EU level as well as for plant protection products at Member State level. The effect assessment schemes in this GD allow for the derivation of regulatory acceptable concentrations (RACs) on the basis of two options: (1) the ecological threshold option (ETO), accepting negligible population effects only, and (2) the ecological recovery option (ERO), accepting some population-level effects if ecological recovery takes place within an acceptable time period. In the tiered effect assessment schemes, in principle, all tiers (1, 2 and 3) are able to address the ETO, while the model ecosystem approach (tier 3), under certain conditions, is able to also address the ERO. The GD provides the scientific background for the risk assessment to aquatic organisms in edge-of-field surface waters and is structured to give detailed guidance on all assessment steps. An executive summary joining all parts of the guidance and decision schemes in a concise way is provided and is intended to help applicants and regulatory authorities in day-to-day use. © European Food Safety Authority, 2013
Detection of T. gondii infection in blood donors in Alexandria, Egypt, using serological and molecular strategies

Background Toxoplasmosis is a widespread disease caused by the opportunistic parasite Toxoplasma gondii, with variable overall prevalence according to the different geographical areas. Blood donors pose as possible contributors for transfer of infection. Objective The aim of this study was to estimate the prevalence of exposure to Toxoplasma in blood donors using sensitive techniques in a cross-sectional study. Materials and methods An aggregate of 150 blood donors from the blood donation center of Alexandria University participated in this study. The blood samples were tested for the presence of T. gondii immunoglobulin (Ig) G antibody and target gene B1 using enzyme-linked immunosorbent assay and real-time PCR, respectively. Results Of 150 participants, 65.3% tested were positive for anti-Toxoplasma IgG, and 10% showed parasitemia as B1 gene was successfully amplified in nine seropositive samples and in six seronegative samples. Conclusion The recorded IgG seropositivity in this selected group of individuals may be considered an indication of the general prevalence of toxoplasmosis in Alexandria. Detected parasitemia using real-time PCR draws attention to the possibility of transmission through blood transfusion even from seronegative donors and emphasizes the importance of specialized Toxoplasma DNA screening before donation of blood.
Study of the addition of the hybrid sisal fibers on the dynamic mechanical property of SFs reinforced polylactic acid (PLA) composites

When sisal fiber (SF) is added into polylactide (PLA) matrix, the storage modulus of PLA/SF composites increases greatly which indicate the rigidity of the composite material increases obviously. Comparing PLA composites with pure PLA, it can be found that the glass transition temperature (Tg) of PLA composites is significantly higher than that of PLA which showed the heat resistance of the PLA composites can be improved obviously because of the addition of SFs in PLA matrix. The energy storage modulus of PLA/HSFs is the highest of all PLA composites. HSFs could improve the dynamic mechanical properties of PLA composites more significantly than ASFs and USFs.
Food Consumption within Greek Households: Further Evidence from a National Representative Sample

The aim of this study is to characterize the relationship between food consumption and socio-demographic characteristics in several groups of individuals. This is achieved by capturing the quantity of food purchased in categories on a microeconomic level. The empirical analysis is approached through the estimation of (a) expanded generalized linear models, (b) quantile regression models, (c) quadratic almost ideal demand system models and (d) Deaton’s (1988) approach. The results reveal that the composition of a household has a significant impact on the quantity of food consumed. In addition, price and income elasticities are estimated, confirming that the majority of food items are inelastic with respect to price and income except for meat. These findings can be used as a basis for considering food policy implications while evaluating the potential gains from applying specific policies.
Rational Molecular Design of Benzoquinone‐Derived Cathode Materials for High‐Performance Lithium‐Ion Batteries

p‐Benzoquinone (BQ) is a promising cathode material for lithium‐ion batteries (LIBs) due to its high theoretical specific capacity and voltage. However, it suffers from a serious dissolution problem in organic electrolytes, leading to poor electrochemical performance. Herein, two BQ‐derived molecules with a near‐plane structure and relative large skeleton: 1,4‐bis(p‐benzoquinonyl)benzene (BBQB) and 1,3,5‐tris(p‐benzoquinonyl)benzene (TBQB) are designed and synthesized. They show greatly decreased solubility as a result of strong intermolecular interactions. As cathode materials for LIBs, they exhibit high carbonyl utilizations of 100% with high initial capacities of 367 and 397 mAh g−1, respectively. Especially, BBQB with better planarity presents remarkably improved cyclability, retaining a high capacity of 306 mAh g−1 after 100 cycles. The cycling stability of BBQB surpasses all reported BQ‐derived small molecules and most polymers. This work provides a new molecular structure design strategy to suppress the dissolution of organic electrode materials for achieving high performance rechargeable batteries.

Keratoconus: advances in anterior lamellar keratoplasty techniques

ABSTRACT Introduction: Deep anterior lamellar keratoplasty (DALK) is nowadays considered the gold standard for the surgical treatment of keratoconus thanks to the lower rate of complications compared to conventional penetrating keratoplasty (PK). However, the learning curve and the suboptimal quality of donor-recipient interface still remain debated issues. Areas covered: To date, big-bubble DALK (BB-DALK) is the most widely performed technique. However, the introduction of femtosecond laser has given new impulse to the standardization of DALK, but also new drawbacks to deal with. Furthermore, the recent redefinition of corneal anatomy understanding along with the introduction of novel techniques have provided further advantages in terms of success rate and postoperative visual outcomes. Expert commentary: Although DALK is still dependent on single surgeon experience and skills, techniques and tools employed are quickly evolving thus improving surgical outcomes. However, to date, there is no universal consensus about alternative options in case of BB-DALK failure as well as management of intra-operative complications.
Brand New: A Longitudinal Investigation of Brand Associations as Drivers of Team Identity Among Fans of a New Sport Team

The role of brand associations and team identity in the sport management literature has received significant attention; however, there exists opportunities to investigate the way they impact one another over time. The authors examined the development of brand associations and team identification among fans of a new team to measure the impact the team’s brand held in the development of new fans. Longitudinal quantitative data were collected from fans of a new professional baseball team (N = 119) across three points during the team’s inaugural season. Using multilevel growth curve modeling, unconditional growth curve models provided evidence of the development and change of brand associations and team identification, while conditional growth curve models evaluated the percentage of change in team identity explained by the changes in each brand association. The findings provide evidence of brand associations as drivers in the development of team identification among fans of a new team.
Flipped Learning for Repurposing EFL Class Time in Moroccan University

This article demonstrates the way flipped learning is implemented in response to new learning environment to solve inadequacies in setting and enhance learning and teaching practices. Accordingly, in the Faculty of Arabic Language in Marrakech, flipped classroom is adopted as a pedagogical solution to approach novel occurrences in teaching and learning context, namely students’ irregular classroom attendance and quantity and variety of instructional material the students have to assimilate within an allotted time to meet deadlines. The question raised seeks to discover the extent flipped pedagogy is successful in improving the teaching and learning performances despite the mentioned inadequacies. For this purpose, and following flipped methodology, the course is disseminated to the learners through a technologybased tool of communication and physical classroom time is managed for discussion purposes rather than lecturing in a traditional way. The success of this implementation is measured through the assessment of the students’ performance in both online quizzes and on-campus exams. Pedagogical benefits and pending points in the implementation of such method in this particular context is thoroughly debated with the purpose to highlight the implications of this empirical case study for educators and researchers.
Experiences to Chemotherapy among Women with Breast Cancer

Few qualitative studies explore patients’ experience due to receiving chemotherapy agents. Issues, such as how such changes impact daily life and functioning, their consequences, and how patients respond to chemotherapy changes, have not previously been systematically addressed. This is a qualitative-research, case study approach which describes the experiences to chemotherapy among women with breast cancer. Data were collected through face-to-face, semi-structured interview guide approach with each of the participants. Holloway’s Strategy was used subsequently to analyze the data. The data emerged a trajectory consisting of the effects of chemotherapy on the physical health, social, emotional, and spiritual aspects of women with breast cancer. In conclusion, there is relief in that their stories were heard with appreciation, their lives gained more value, and meaning to people who matter most to them. It is recommended that breast cancer education and information campaign should be intensified. It should not only include the signs and symptoms for its early detection, the various treatment and their side effects and selfcare to be practiced correctly but also to present these in a positive perspective through the stories of hope, strength, and love of the cancer survivors.
An integrated fuzzy-AHP and TOPSIS approach for maintenance policy selection

PurposeThe purpose of this paper is to select the best maintenance policy for different types of equipment of a manufacturer integrating the fuzzy analytic hierarchy process (FAHP) and the technique for order of preference by similarity to ideal solution (TOPSIS) models.Design/methodology/approachThe decision hierarchy of this research includes three levels. The first level aims to choose the best maintenance policy for different types of equipment of an acid manufacturer. These equipment pieces include molten sulfur ponds, boiler, absorption tower, cooling towers, converter, heat exchanger and sulfur fuel furnace. The second level includes decision criteria of added-value, risk level and the cost. Lastly, the third level comprises time-based maintenance (TBM), corrective maintenance (CM), shutdown maintenance and condition-based maintenance (CBM) as four maintenance policies.FindingsThe best maintenance policy for different types of equipment of a manufacturer is the main finding of this research. Based on the obtained results, CBM policy is suggested for absorption tower, boiler, cooling tower and molten sulfur ponds, TBM policy is suggested for converters and heat exchanger and CM policy is suggested for a sulfur fuel furnace.Originality/valueThis research develops a novel model by integrating FAHP and an interval TOPSIS with concurrent consideration of added-value, risk level and cost to select the best maintenance policy. According to the highlights of the previous studies conducted on maintenance policy selection and related tools and techniques, an operative integrated approach to combine risk, added-value and cost with integrated fuzzy models is not developed yet. The majority of the previous studies have considered classic fuzzy approaches such as FAHP, FANP, Fuzzy TOPSIS, etc., which are not completely capable to reflect the decision makers’ viewpoints.

 mborella
 
 – Bearing Witness to the Past?

Amborella trichopoda (Amborellaceae) is a shrub endemic to New Caledonia in the Southwest Pacific region. This plant suddenly became famous when molecular phylogenetic studies revealed that this sole species is likely the sister taxon to all other angiosperms. It has thus been a prime research model for reconstructing plant evolution and gaining insight into what the earliest angiosperms looked like. A wealth of studies on Amborella have now shed considerable light on its genome, morphology, anatomy, physiology, development, and architecture – this research is reviewed in this article. While Amborella likely retained some ancestral traits, critical character reconstructions have also highlighted some derived and sometimes unique characters in this species. The history of Amborella is also tied to the South Pacific archipelago of New Caledonia, its homeland. It was part of the New Caledonian biogeography puzzle and its genetic history shed light on the dynamics of its ecosystem, the rainforest understorey. Amborella is now cultivated in botanical gardens and has been the focus of some conservation measures that will also benefit other species in this biodiversity hotspot.
Hemilaminectomy and Bilateral Decompression for Thoracic Spinal Stenosis.

AIM To establish the effectiveness and reliability of the hemilaminectomy and bilateral decompression (HLBD) for the treatment of Thoracic Spinal Stenosis (TSS) in selected patients. MATERIAL AND METHODS We reviewed the clinical data of 21 consecutive adult patients who had undergone HLBD. The patients whose diagnosis of TSS was confirmed by CT or MRI, and whose stenosis was secondary to hypertrophy on the posterior elements, and who were performed HLBD for treatment of narrow spinal canal were included in this study. Using medical records, we evaluated the patients by pre- and postoperative Japanese Orthopedic Association (JOA) scores. The recovery rates were evaluated according to Hirabayashi's method. RESULTS The mean follow-up period was 37.6 months. The average age was 61.6 years. The preoperative mean JOA score was 5.8. The postoperative improved mean JOA score was 9.9 in follow-up. The recovery rate was 83.3%. There was no operation-related transfusion, neurological deterioration and postoperative instability in the follow-up examination. CONCLUSION Having a relatively less complication ratio, protecting posterior anatomical structures, avoiding post laminectomy kyphosis and postsurgical instability, and providing successful clinical improvement, HLBD is a suitable technique for the patients whose stenosis is mainly secondary to hypertrophy on the posterior elements such as ligamentum flavum and facet joints.
Isolation of singlet carbene derived 2-phospha-1,3-butadienes and their sequential one-electron oxidation to radical cations and dications

Compounds 3a and 3b have a remarkably small HOMO–LUMO energy gap (3a: 5.09; 3b: 5.05 eV) with a very high-lying HOMO (−4.95 eV for each). Consequently, 3a and 3b readily undergo one-electron oxidation with the mild oxidizing agent GaCl3 to afford radical cations [{(IPr)C(Ph)}P(cAACR)]GaCl4 (R = Me 4a, Cy 4b) as crystalline solids. The main UV-vis absorption band for 4a and 4b is red-shifted with respect to that of 3a and 3b, which is associated with the SOMO related transitions. The EPR spectra of compounds 4a and 4b each exhibit a doublet due to coupling of the unpaired electron with the 31P nucleus. Further one-electron removal from the radical cations 4a and 4b is also feasible with GaCl3, affording the dications [{(IPr)C(Ph)}P(cAACR)](GaCl4)2 (R = Me 5a, Cy 5b) as yellow crystals. The molecular structures of compounds 3–5 have been determined by X-ray diffraction and analyzed by DFT calculations.
