Efficient Language Learning with Correction Queries

We investigate two of the language classes intensively stud ied by the algorithmic learning theory community in the context of learning wit h correction queries. More precisely, we show that any pattern language can be infe rred in polynomial time in length of the pattern by asking just a linear numb er of correction queries, and that k-reversible languages are efficiently learnable within thi s setting. Note that although the class of all pattern languages i s learnable with membership queries, this cannot be done in polynomial time. Mor eover, the class of k-reversible languages is not learnable at all using member ship queries only. Furthermore, we present results on a newly introduced class of l anguages, namely the class of injective languages.
Numerical Evaluation of a Seed Distributor Head for Air Seeders

In previous work, the authors analyse the behaviour of the airflow-seed mixture in distributor heads of air drill seeders. Numerical simulations and laboratory tests performed on a commercial distributor head show similar results, and indicate that most seeds escape through the front outlets ducts. In this paper, the behaviour of a distributor head model, in different working conditions, is studied. The distributor head analysed is designed by the authors (Bourges et al, 2015). Constant air flow and two different sizes of seeds is simulated. In both cases, the seeds are modelled as spherical particles of homogeneous size. Soybean (Glycine max ) and amaranth. (Amaranthus cruentus) are used in numerical test.
Structural Characterization of ABCB1, the Gene Underlying the d2 Dwarf Phenotype in Pearl Millet, Cenchrus Americanus (L.) Morrone

Pearl millet is an important food crop in arid and semi-arid regions of South Asia and sub-Saharan Africa and is grown in Australia and the United States as a summer fodder crop. The d2 dwarf germplasm has been widely used in the last half-century to develop high-performing pearl millet hybrids. We previously mapped the d2 phenotype to a 1.6 cM region in linkage group (LG) 4 and identified the ABCB1 gene as a candidate underlying the trait. Here, we report the sequence, structure and expression of ABCB1 in tall (D2D2) and d2 dwarf (d2d2) germplasm. The ABCB1 allele in d2 dwarfs differs from that in tall inbreds by the presence of two different high copy transposable elements, one in the coding region and the second located 664 bp upstream of the ATG start codon. These transposons were present in all d2 dwarfs tested that were reported to be of independent origin and absent in the analyzed wild-type tall germplasm. We also compared the expression profile of this gene in different organs of multiple tall and d2 dwarf inbreds, including the near-isogenic inbreds at the d2 locus, Tift 23B (D2D2) and Tift 23DB (d2d2). Heterologous transformation of the tall (Ca_ABCB1) and the d2 dwarf (Ca_abcb1) pearl millet alleles in the Arabidopsis double mutant abcb1abcb19 showed that the pearl millet D2 but not the d2 allele complements the Arabidopsis abcb1 mutation. Our studies also show the importance of the COOH-terminal 22 amino acids of the ABCB1 protein in either protein function or stability.

Climbing the ladder of decline: Income and acculturation associated with chronic inflammation among Mexican immigrants

Financial hardship and immigrant status are often associated with poorer health as immigrant groups acculturate to life in the US. Known as the Latino health paradox, studies have shown that Latino/a immigrants in particular often experience declines in health the more they embrace ways of life considered “dominant” by US society. At present, critical biological pathways linking socioeconomic and acculturative processes remain to be better explained. The present study investigates associations among financial strain, acculturation, and chronic inflammation.
Impact of edible coatings based on cassava starch and chitosan on the post-harvest shelf life of mango (Mangifera indica) ‘Tommy Atkins’ fruits

The mango (Mangifera indica L.) is one of the most consumed fruits in the world, either in its fresh form or as derived products, such as pulp, juice, nectar, jam and jelly (Canuto et al., 2009). Brazil is a major producer of mango (Pinto et al., 2011; Souza et al., 2011) and it exported 156 thousand tons of mango in the year 2015, leading the country to occupy 7th place among the world’s largest mango exporters (Singh et al., 2013). Morever, due to the large European demand for tropical fruits, this market still presents large growth potential (Hojo et al., 2009). However, the fruits marketed especially in the international market, require high quality products (Gomes et al., 2010). Thus, in order for the country to participate more effectively in the international market, it is necessary to use technologies that extend and guarantee fruit quality after harvest along with an incresed shelf life (Hojo et al., 2009).
Assessing students in senior science: An analysis of questions in contextualised chemistry exams

This study explores the development of a coding system for analysing test questions in two context-based chemistry exams. We describe our unique analytical procedures before contrasting the data from both tests. Our preliminary findings indicate that when a new curriculum is developed such as a context-based curriculum, teachers are required to combine the previously separate domains of context and concept to develop contextualised assessment. We argue that constructing contextualised assessment items requires teachers to view concepts and context as interconnected rather than as separate entities that may polarise scientific endeavour. Implications for theory, practice, curriculum and assessment-development in context-based courses are proposed.
Miniaturized Bandstop Filter Using Meander Spurline and Capacitively Loaded Stubs

A miniaturized bandstop filter (BSF) is introduced in this paper. The filter consists of one meander spurline and a pair of capacitively loaded stubs. The meander spurline with low resonant frequency and improved slow‐wave factor exhibits excellent resonant bandgap characteristics which can be modeled by a longitudinally coupled resonator. The design of the proposed microstrip BSF is presented, and its performance is measured. Measurements show that there is a stopband from 2.3 to 5.6 GHz with S21 less than –20 dB. The total length of this BSF equals 23 mm.
Non-galvanic Interconnects for Millimeter-wave Systems

Fueled by the increasing demand for higher data rates, millimeter-wave (mmW) systems emerged as a candidate that can provide multi-gigabit per second (Gb/s) transmission. This demand is mainly driven by modern communication systems and several other wireless and sensing applications such as production quality inspection and imaging systems. The full realization of such systems has been always challenged by the lack of low-loss low-cost interconnects and high-level integration. This challenge is more critical in systems operating beyond 100 GHz where conventional packaging techniques would not be suitable from performance perspective. D-band offers a wide spectrum ranging from 110 to 170 GHz and hence providing wide bandwidth that makes it suitable for high data rate systems. In this thesis, several interconnects that operate at D-band are presented. Different technologies were used to realize the interconnects. Two interconnects are realized in Embedded Wafer Level Ball Grid Array (eWLB) packaging technology. The technology has been widely used for low frequency applications. The proposed interconnects are based on slot antennas radiating to a standard air-filled waveguides. The interconnects achieve an average insertion loss of 3 dB and 3.4 dB across the frequency ranges 110-138 GHz and 116-151 GHz respectively. The proposed interconnects are generic and do not require any galvanic contacts. The utilized eWLB packaging technology is suitable for low-cost high-volume production and allows heterogeneous integration with other technologies as well. A chip-to-waveguide transition based on unilateral finline structure is also demonstrated. The interconnect consists of a microstrip line implemented on a 75 um-thick substrate. The line then couples to a unilateral finline taper that is mounted in the E-plane of a standard D-band waveguide. The transition achieves a very low loss of only 0.7 dB and covers a very wide band ranging from 110 to 170 GHz. A chip-to-waveguide transition in a commercial MMIC technology is also presented. The transition is based on Linearly Tapered Slot antenna (LTSA) structure. The antenna is implemented on a 50 um-thick Gallium Arsenide (GaAs) substrate. The transition exhibits an insertion loss of 1 dB across the frequency range 110-170 GHz. This work presents low-cost high-performance mmW interconnects and addresses integration challenges facing systems operating beyond 100 GHz paving the way for high-volume commercialization of such systems in the future.
Eye Tracking Application on Emotion Analysis for Marketing Strategy

This paper present on understanding the human behavior with eye tracking studies related to consumer cognition in marketing product. The study of human behavior using eye tracking is a growing multidisciplinary field that links electronics, psychology and cognitive science to study the human behavior on problem solving and decision making. In this paper, we particularly investigate the human behavior in consumer cognition. We conducted experiments to track the human eyes by using the Tobii TX300 eye tracker. The eye–mind relationship can help to use eye motions activity measurements expressing to some degree about human behavior. The result shows that the visual attention of human is very much related to the cognition of the products.
Software ‐ defined optical network architecture

Featured by the advantages of high capacity, long transmission distance, and low energy consumption, optical network has been deployed widely as the most important infra‐ structure for backbone transport network. With the development of Internet, datacenter has become the popular infrastructure for cloud computing, which needs to be connected with high bitrate transport network to support heterogeneous applications. In this case, optical network also becomes a promising option for intra and inter‐datacenter network‐ ing. In the networking field, software‐defined networking (SDN) has gained a lot of attention from both academic and industry, and it aims to provide a flexible and pro‐ grammable control plane. SDN is applicable to optical network, and the optical network integrated with SDN, namely software‐defined optical network (SDON), are expected as the future transport solutions, which can provide both high bitrate connectivity and flexible network applications. The principles and applications of SDON are introduced in this chapter.
Intelligent sensor management to minimize detection error

This paper analyzes the impact on target detection of several alternative sensor management schemes. Past work in this area has shown that myopic discrimination optimization can be a useful heuristic. In this paper we compare the performance obtained using discrimination with direct optimization of the detection error rate using both myopic and non-myopic optimization techniques. Our model consists of a gridded region containing a set of targets with known priors. Each grid location contains at most one target. At each time step, the sensor can sample a grid location, returning sample values that may or may not be thresholded. The sensor output distribution conditioned on the content of the location is known. Bayesian methods are used to recursively update the posterior probability that each location contains a target. These probabilities can then in turn be used to classify each location as either containing a target or not. At each time step, sensor management is used to determine which location to test next. For non-myopic optimization, graph search techniques are used. When the sensor output is thresholded, the performance obtained using myopic optimization of the expected error rate is worse then that obtained using our other three approaches. Interestingly, we find that for non-thresholded measurements on symmetric distributions, the performance is the same for the four cases tested (myopic/non-myopic discrimination gain/expected error rate). This supports that discrimination is a useful heuristic that provides near-optimal performance under the given assumptions.

Migraine: Experimental Models and Novel Therapeutic Approaches

Migraine is a disorder affecting an increasing number of subjects. Currently, this disorder is not entirely understood, and limited therapeutic solutions are available. Migraine manifests as a debilitating headache associated with an altered sensory perception that may compromise the quality of life. Animal models have been developed using chemical, physical or genetic modifications, to evoke migraine-like hallmarks for the identification of novel molecules for the treatment of migraine. In this context, experimental models based on the use of chemicals as nitroglycerin or inflammatory soup were extensively used to mimic the acute state and the chronicity of the disorder. This manuscript is aimed to provide an overview of murine models used to investigate migraine pathophysiology. Pharmacological targets as 5-HT and calcitonin gene-related peptide (CGRP) receptors were evaluated for their relevance in the development of migraine therapeutics. Drug delivery systems using nanoparticles may be helpful for the enhancement of the brain targeting and bioavailability of anti-migraine drugs as triptans. In conclusion, the progresses in migraine management have been reached with the development of emerging agonists of 5-HT receptors and novel antagonists of CGRP receptors. The nanoformulations may represent a future perspective in which already known anti-migraine drugs showed to better exert their therapeutic effects.
Osmanicin, a Polyketide Alkaloid Isolated from Streptomyces osmaniensis CA-244599 Inhibits Elastase in Human Fibroblasts

The strain Streptomyces osmaniensis CA-244599 isolated from the Comoros islands was submitted to liquid-state fermentation coupled to in situ solid-phase extraction with amberlite XAD-16 resin. Elution of the trapped compounds on the resin beads by ethyl acetate afforded seven metabolites, osmanicin (1), streptazolin (2), streptazone C (3), streptazone B1 (4), streptenol C (5), nocardamine (6) and desmethylenylnocardamine (7). Osmanicin (1) is a newly reported unusual scaffold combining streptazolin (2) and streptazone C (3) through a Diels-Alder type reaction. Experimental evidence excluded the spontaneous formation of 1 from 2 and 3. The isolated compounds were evaluated for their ability to inhibit elastase using normal human diploid fibroblasts. Compound 1 exhibited the most potent activity with an IC50 of 3.7 μM.
Methionine-supplemented diet increases the general performance and value of Rahmani lambs.

Essential amino acids such as methionine have been increasingly included into diets of lambs. However, few studies have determined the effects of methionine supplementation in the general performance and economic returns of lamb production. To address this question, 21weaned male Rahmani lambs were allotted to 3 dietary treatments: control diet (C), control diet plus 3.30 g of methionine/kg concentrate feed mixture (T1), and control diet plus 3.63 g of methionine/kg concentrate feed mixture (T2). T1-fed lambs showed significantly higher (P<0.05) total body weight gain than those fed diets C. The digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), ether extract, (EE), and nitrogen free extract (NFE) for T1 and T2 were significantly better (P<0.05) than for C. Economically, dietary feed T1 and T2 increased the net profit by 329.64 Egyptian pounds EGP/lamb and 305.76 EGP/lamb, respectively, as compared with the control diet. In addition, the economic efficiency (average feed cost/kg of body weight gain) was 10.02 for C and T1 and 10.48 for T2. Total costs were similar between the 3 dietary treatments. In conclusion, feeding growing Rahmani lambs with 3.30 g of methionine/kg concentrate feed mixture improved their growth performance and raised their economic value.
Subgrid models for large-eddy simulation using unstructured grids in a stabilized finite element framework

We present subgrid closures for large-eddy Simulation (LES) likely to be implemented in stabilized finite element methods. Selection criterion, dynamic procedure and multiscale approach are compared within simulations of freely decaying isotropic turbulence. In all cases, the numerical dissipation coming from the least-squares stabilization dominates the subgrid model. Despite this large numerical dissipation, the LES model, whichever it is, provides a sufficient physical dissipation to have a clear and major effect on the results. In particular the dynamic procedures and the multiscale models turn out to be very efficient, high-lighting a self-adaptive behaviour of the turbulent viscosity and consequently predict the correct energy transfer mechanisms, by accounting for the numerical part of the total dissipation.
Introduction of Actinomycetes Starter on Coffee Fruits Fermentation to Enhance Quality of Coffee Pulp

Coffee pulp contains bioactive compounds such as polyphenols and aldehydes, which are covalently linked to the pulp cell wall. The research aimed to determine of potential Actinomycetes concortia on the degradation of coffee pulp to enhance the yield and quality of coffee pulp polyphenol extracts. In this study, whole coffee fruit were fermented in solid-state cultivation by using concortia of Streptomyces exfoliatus 42 and Streptomyces costaricanus 45I-3 that having cellulolytic and xylanolytic activities. The introduction of Actinomycetes starter accelerated the fermentation which caused the degradation of lignocellulosic components of coffee pulp, and significantly effects on the yield of bioactive compounds such as polyphenols, anthocyanins, tannins, and catechin. Compared to the spontaneous fermentation of coffee fruit, the highest yield of bioactive components extracts produced from 6th day incubation for total polyphenols (1.20 mg mL-1), anthocyanin (109.95 mg mL-1) and the highest yield of catechin (10.38 mg mL-1) produced form 3th day incubation, but introduction of Actinomycetes reduced the tannin contents after fermentation.
THE SIMPLE DYNAMICS OF PUBLIC DEBT WITH PRODUCTIVE PUBLIC GOODS

This paper analyzes the dynamics of public debt in a simple two-period overlapping-generations model of endogenous growth with productive public goods. Alternative fiscal rules are defined, with particular attention devoted to the golden rule. Conditions under which multiple equilibria may emerge are characterized. The analysis is then extended to consider the case of partial depreciation, an endogenous risk premium, an endogenous primary surplus rule, a generalized golden rule, a nonseparable utility function, and network externalities. If network effects are sufficiently strong, an increase in public investment may shift the economy from a low-growth equilibrium to a steady state characterized by both higher public debt ratios and higher output growth. This shift may enhance welfare as well. These results illustrate the importance of preserving, even in a context of fiscal retrenchment, the allocation of resources to specific types of public investment.
OWNERSHIP STRUCTURE AND STOCK MARKET PERFORMANCE OF ACQUIRING FIRMS: THE CASE OF FRENCH MERGERS

The link between ownership structure and financial performance of acquiring firms has been given an extensive attention in the academic literature. Previous studies provide mixed results, which are explained by various ownership structure mechanisms. In the French context, shareholding is characterized by the abundant presence of families and institutional investors, as well as a high level of concentration, to which we point out the weak legal protection of investors. Jensen and Meckling (1976) define the agency relationship as a contract under which one party (the principal) engages another (the agent) to perform some service on their behalf. However, the agents do not communicate all the information to the principals (asymmetric information). The latter are then forced to develop proper corporate governance mechanisms to efficiently monitor the management and guarantee value maximization. The ownership structure acts as an important governance system. Thus, the proportion held by a shareholder influences his interest in the monitoring. As a consequence, his investment in the governance is greater as his ownership stake increases. Moreover, Demsetz and Lehn (1985), Shleifer and Vishny (1986) document the disciplinary role of shareholders over managers and anticipate the achievement of a better performance. Fama and Jensen (1983) suggest an opportunistic behaviour by controlling shareholders that use mergers and acquisitions in order to extract private benefits. According to Shleifer and Vishny (1997), the entrenchment of the large shareholder is detrimental to financial performance whereas Ellili (2012) shows that managerial entrenchment is not always harmful to shareholder’s wealth. Thus, it is difficult to Abstract
Restructuring foreign language lexical knowledge: do cognitive linguistic insights contribute to foreign language learning?

This study examined the effectiveness of a cognitive linguistics (CL) approach in improving the foreign-language learner’s knowledge of polysemous English prepositions (at, in, on). Japanese learners of English as a foreign language studied the target prepositions, using either the materials focusing on the core and peripheral senses of each preposition (i.e., the CL-approach group) or those listing the definitions and usages of each preposition from a bilingual dictionary (i.e., the control group). Before and after the learning stage, an original test developed to evaluate the participant’s knowledge in usage of the target prepositions was administered. Results showed no observable advantages of learning the core and peripheral senses of the prepositions over the control group. Two potential reasons are proposed: the difficulty in learning the peripheral senses of a polysemous word and first-language effects on conceptualization in foreign language learning.
