Resource allocation to growth or luxury consumption drives mycorrhizal responses.
Venue: Ecology letters
Year: 2019

Highly variable phenotypic responses in mycorrhizal plants challenge our functional understanding of plant fungal mutualisms. Using non invasive high throughput phenotyping, we observed that arbuscular mycorrhizal (AM) fungi relieved phosphorus (P) limitation and enhanced growth of Brachypodium distachyon under P limited conditions, while photosynthetic limitation under low nitrogen (N) was exacerbated by the fungus. However, these responses were strongly dependent on host genotype: only the faster growing genotype (Bd3 1) utilised P transferred from the fungus to achieve improved growth under P limited conditions. Under low N, the slower growing genotype (Bd21) had a carbon and N surplus that was linked to a less negative growth response compared with the faster growing genotype. These responses were linked to the regulation of N P stoichiometry, couples resource allocation to growth or luxury consumption in diverse plant lineages. Our results attest strongly to a mechanism in plants by which plant genotype specific resource economics drive phenotypic outcomes during AM symbioses.
Robust relationship learning to illumination in a camera network
Venue: 2018 International Conference on Electronics, Information, and Communication (ICEIC)
Year: 2018

Multi target tracking in a camera network is one of the fastest growing fields. Re identification is one of the most important and challenging parts of multi target multi camera tracking. In this paper, we introduce an approach to overcome illumination change problems. The proposed framework uses convolutional neural networks to extract features and then computes relationship matrices based on connectivity between the features. The framework is trained to avoid the ambiguity of objects that are seriously affected by illumination changes. The relationship matrix is calculated by feature matrices based on multiple brightness, which is learned by considering all the brightness cases. Experimental evaluation shows that the proposed method outperforms state of the art competitors.
Morphological changes recorded in different phenophases of sugarcane plants subjected to water stress in tropical field conditions
Year: 2018

Nowadays, water deficit is one of the major environmental stress issues affecting sugarcane crops around the world. It has been causing significant production decrease due to the increased mortality rates generated by water stress in sugarcane plantations. The aim of the current study is to assess sugarcane morphological and yield responses during different phenophases of sugarcane varieties when plants are subjected to drought stress in the fields of a tropical region. Six sugarcane varieties, namely: SP79 1011, RB855113, RB92579, RB867515, RB72454, and RB855536, were subjected to water stress. The herein adopted water regimes were (i) irrigated crop and (ii) crop subjected to natural drought in the field. Plants were cultivated under water stress imposition throughout three phenological stages (i) tillering, three months after planting; (ii) intense growth, seven months after planting; and (iii) ripening, eleven months after planting. The irrigation treatment consisted of supplementing the crop with 50 mm of water per month during the dry season, whereas non irrigated plants were naturally grown under water stress conditions throughout the experiment. Water stress mostly affected the sugarcane crop during the intense growth phase. Varieties RB72454 and RB855536 presented smaller green leaf number, as well as narrower leaf width and smaller leaf area under water stress; besides, they showed low productive potential and high stress susceptibility index (SSI) Stalk height maintenance and the larger number of tillers in RB92579 plants subjected to water stress helped balancing yield rates. This variety also showed the best drought tolerance (DTI) and yield/tolerance indices (YTI) moreover, the principal component analysis evidenced that leaf area, plant height and yield were important factors to distinguish the most tolerant varieties. Such results show that RB92579 is more drought tolerant and has better physiological acclimation potential than the other five varieties; therefore, it can be recommended for crops subjected to drought periods.
Treatment of Single Word Writing for A Malay Patient with Acquired Dysgraphia following Stroke: A Single Case Experimental Study
Year: 2017

Disruption to the processes that supports spoken language in people with aphasia following stroke also tend to interfere with the ability to write or referred to as dysgraphia.  This study examined the effectiveness of a novel treatment for writing by Beeson (1999) administered on a Malay patient (GM) who had significant conduction aphasia affecting both spoken and written language. GM received Anagram and Copy Treatment (ACT) a clinician directed treatment that required the arrangement of component letters presented in scrambled order (i.e. an anagram) for the patient to form a target word, followed by repeated copying of the word. Single subject multiple baseline design was used with sets of words (both nouns and verbs) sequentially targeted for treatment. Prior to the initiation of the writing treatment, a series of single word writing and reading assessments were conducted. Probes assessing generalizations to untrained pictures were presented at 8th, 13th and 18 th sessions. The assessments were repeated after the treatment was completed in order to monitor the progress of the writing treatment.  Prior to treatment, GM showed minimal ability to write words, but subsequently demonstrated rapid learning for spelling of the words targeted. He showed steady improvement in the writing of trained nouns and verbs: from 0 10% baseline accuracy to over 90% accuracy at end of treatment for nouns and verbs. Generalizations to untrained nouns and verbs also showed similar results. GM exhibited marked progress: from able to write 22 nouns (44% and 19 verbs (38% in the first probe to 47 nouns (94% and 38 verbs (76% in final probe. Pre and post assessments results revealed that GM performed better in all of the tasks measured.  Single word writing treatment may improve dysgraphia among adults with aphasia through the administration of a structured and systematic treatment.

Localized ZnO growth on a gold nano antenna by plasmon assisted hydrothermal synthesis.
Venue: Nano letters
Year: 2019

The excitation of localized surface plasmon resonances (LSPR) in metal nanostructures enables subwavelength photon localization and large electric field enhancement, which can be advantageously used to strongly enhance light matter interactions at the nanoscale. For this purpose, efficient methods for deterministically handling and arranging nanomaterials at the exact position of the localized electric field are required. In this letter, we propose a novel method based on a hydrothermal synthesis reaction to locally and selectively synthetize zinc oxide in a plasmonic nano antenna. We first evidence the role of LSPR for achieving efficient heating of gold nanostructures. Then, by selectively addressing one of the LSPR of a gold antenna, we demonstrate that localized zinc oxide formation at the targeted location of the antenna can be achieved due to the nanoscale confinement of the heat production.

Research on PV Power Forecasting Based on Wavelet Decomposition and Temporal Convolutional Networks
Venue: 2021 IEEE 4th International Electrical and Energy Conference (CIEEC)
Year: 2021

Photovoltaic power generation generally exhibits periodicity and volatility. Large scale integration of photovoltaic power generation into the grid will bring challenges to the stability and security of the grid system, and inaccurate output power prediction will bring great impact to the grid. Therefore, accurate photovoltaic power generation prediction is very important for power system dispatch. This paper proposes a temporal convolutional networks model based on wavelet decomposition to predict short term photovoltaic power generation. First, in order to extract the time frequency information of the input feature, the input feature is decomposed into several component sequences using wavelet decomposition. Then, a case study was carried out using photovoltaic power generation data from a certain region in South China, and the feasibility of the temporal convolutional networks model based on wavelet decomposition proposed in this paper was tested. The research results show that the temporal convolutional networks after wavelet decomposition has slightly higher prediction accuracy than the long short term memory networks, but the operating efficiency of this method is greatly improved.
An Approach to the Analysis of Religious Reality in the Social Phenomenology of Alfred Schutz
Year: 2019

The article deals with the social phenomenology of Alfred Schutz. Proceeding from the concept of multiple realities, the author describes religious reality, analyses its relationship with everyday, theoretical, and mythological realities, and identifies the areas where they overlap and their specifics. According to Schutz's concept, reality is understood as something that has a meaning for a human being, and is also consistent and certain for those who are 'inside' of it. Realities are structurally similar to one another as they are similar to the reality that is most obvious for all human beings, i.e. the world of everyday life. Religious reality has one of the main signs of genuine reality, that of internal consistency. Religious reality has its own epoche (special ascetic practices) which has similarities with the epoche of the theoretical sphere since neither serve practical objectives, and imply freedom from the transitory issues of everyday life. Just as the theoretical sphere exists independently of the life of a scientist in the physical world and is needed to transfer results to other people, so the religious reality depends on ritual actions and material objects in its striving for the transcendent. Individual, and especially collective, religious practices are performed physically and are inextricably linked with the bodily ritual. The article notes that although Schutz's phenomenological concept of multiple realities has repeatedly served as a starting point for the development of various social theories, its heuristic potential has not been exhausted. This allows for the further analyzing and development of topical issues such as national identity and its ties with religious tradition in the modern era, when religious reality loses credibility and has many competitors, one of which is the modern myth of the nation. Intersubjective ideas of the nation that are socially confirmed as the self evident reality of everyday life cause complex emotions and fill human lives, thus displacing religious reality or forcing the latter to come into complex interactions with the national narrative.
Modeling the Influence of Eutrophication and Redox Conditions on Mercury Cycling at the Sediment Water Interface in the Berre Lagoon
Venue: Front. Mar. Sci.
Year: 2018

This study presents a specifically designed Mercury module in a coupled benthic pelagic reactive transport model Bottom RedOx Model (BROM) that allows to study mercury (Hg) biogeochemistry under different conditions. This module considers the transformation of elemental mercury (Hg(0) divalent mercury (Hg(II) and methylmercury (MeHg) The behavior of mercury species in the model is interconnected with changes of oxygen, hydrogen sulphide, iron oxides, organic matter and biota. We simulated the transformation and transport of Hg species in the water column and upper sediment layer under five different scenarios, combining various levels of oxygenation and trophic state in the Berre lagoon, a shallow eutrophic lagoon of the French Mediterranean coast subjected to seasonal anoxia. The first scenario represents the conditions in the lagoon that are compared with experimental data. The four other scenarios were produced by varying the biological productivity, using low and high nutrient (N and P) concentrations, and by varying the redox conditions using different intensity of vertical mixing in the water column. The results of the simulation show that both oxidized and reduced sediments can accumulate Hg, but any shifts in redox conditions in bottom water and upper sediment layer lead to the release of Hg species into the water column. Eutrophication and/or restricted vertical mixing lead to reducing conditions and intensify MeHg formation in the sediment with periodic release to the water column. Oxygenation of an anoxic water body can lead to the appearance of Hg species in the water column and uptake by organisms, whereby Hg may enter into the food web. The comparison of studied scenarios shows that a well oxygenated eutrophic system favors the conditions for Hg species bioaccumulation with a potential adverse effect on the ecosystem. The research is relevant to the UN Minimata convention, EU policies on water, environmental quality standards and Mercury in particular.
Agile governance theory: operationalization
Venue: Innovations in Systems and Software Engineering
Year: 2019

Agile governance has emerged as a relatively new, wide, and multidisciplinary area focused on organizational performance and competitiveness, which until recently had lacked in depth exploration. Aiming to reduce this gap, we recently proposed the Agile Governance Theory to analyze and describe its phenomena, and provide a better understanding of how agility in business can establish effective and responsive governance. This paper describes the process of transposing the theory from a conceptual framework to the real world and developing the necessary measurement elements to test it. We operationalize the emerging theory according to the four remaining steps of part two of Dubin's method: identifying its propositions, deriving empirical indicators from its constructs, and establishing testable hypotheses. We operationalized the emerging theory by: (1) depicting eight theoretical scenarios that help characterize and describe organizational contexts in the real world, (2) recognizing 11 propositions that allow us to predict the behavior of its elements, (3) identifying 24 empirical indicators to measure its constructs, and (4) developing 16 hypotheses to test the theory as a further study. We operationalize the theory to allow real world empirical testing based on this work, as further study is necessary to assess the theory's plausibility. We also make improvements and additions to the methodological approach for theory building research (including Dubin's Method) extending it to a multimethod approach.
CHOLESTEROL DOES NOT IMPROVE CRYOPROTECTIVE EFFICIENCY OF SOYBEAN LECITHIN BASED EXTENDERS FOR BULL SEMEN
Year: 2017

Design of plant phospholipid based extenders free of animal derived components is urgent in farm animal semen cryopreservation. However, a complex of plant lipids, unlike the yolk complex, lacks cholesterol which plays an important role in cryoresistance of spermatozoa. Enriching spermatozoa membranes with cholesterol improves their cryotolerance (E. Moce et al. 2010; E. Moce et al. 2014; M.H. Fayyaz et al. 2016) We first estimated the impact of different cholesterol concentrations (0, 8, 18, 33 and 50 in soybean phospholipid mixtures both on morphology of obtained liposomes or lipid particles, and on their cryoprotective property as judged by the effect on motility when added to the extender at bull sperm cryopreservation. Liposome suspensions were prepared from commercial lecithin LeciPRO 90 <Unite chem Co. Ltd> China) and purified cholesterol form lanolin <Sigma Aldrich Co. USA) by sonication at an ultrasound disintegrator UZDN 2T (NPP <Academpribor> Russia; 22 kHz, 60 W/cm2, 5 min) It was found that cholesterol did not notably influence the obtained liposomes at low concentration (8 At 18 and 33 cholesterol in the lipid mixture the size of the liposomes increased and averaged 66+ 6 nm and 62+ 11 nm, respectively. Fifty percent cholesterol changed the lipid suspension completely resulting in complex structures formed by phospholipid cholesterol lamellae and crystals of cholesterol monohydrate. Eight percent cholesterol did not increase a cryorpotective efficiency of lecithin, while 18 50 cholesterol decreased its cryoprotective capacity. An increase in cholesterol concentration in the lipid mixture up to 50 66 mol% led to somewhat higher spermatozoa motility compared to a minimum score observed at freezing with 33 cholesterol. The most probable cause of the negative impact of cholesterol on the cryoprotective effectiveness of lecithin suspension is impairment in liposome interaction with a sperm plasma membrane caused by condensation of phospholipid packing in a lipid bilayer.
Using Very Large Parsed Corpora and Judgment Data to Classify Verb Reflexivity
Venue: DAARC
Year: 2007

Dutch has two reflexive pronouns, zich and zichzelf. When is each one used? This question has been debated in the literature on binding theory, reflexives and anaphora resolution. Partial solutions have attempted to use syntactic binding domains, semantic features and pragmatic concepts such as focus to predict reflexive choice, but until now no experimental data either in favor of or against one of these theories is available. In this paper we look at reflexive choice on the basis of empirical data: a large scale corpus study and an online questionnaire. On the basis of the results of both experiments, we are able to predict the choice between the two reflexive items in Dutch without assuming a distinction between verbs that occur with zich or zichzelf a priori (cf. a distinction in terms like 'inherent reflexivity' (Reinhart and Reuland, 1993) Instead, we examine the distribution of zich and zichzelf using the Clef corpus, a 70 million word Very Large Corpus of Dutch. The corpus is tagged and parsed. This allows us to identify the typical action the verbs are used to describe: reflexive or non reflexive actions. Regression analysis shows that, by doing so, 21% of the distribution of the two reflexive items in Dutch can be predicted. Using the verb reflexivity found in the corpus study even allows us to explain 83% of the participants' choices in the online study between zich and zichzelf. As such, both the corpus study and the online questionnaire confirm the group of verbs called 'inherent reflexive verbs' without postulating the group beforehand. We further discovered that even inherently reflexive verbs, which are argued to never co occur with zichzelf, sometimes had zichzelf chosen as the preferred argument in the questionnaire, and to a lesser degree, in the corpus suggesting that the verb classes are tendential and not categorical.
Iranian EFL teachers' willingness to implement postmethod pedagogy: A mixed methods study
Year: 2017

The aim of this study was to investigate the Iranian English as a Foreign Language (EFL) teachers' willingness to implement postmethod pedagogy in the Iranian context. In so doing, a mixed methods approach was employed in which first a validated postmethod questionnaire was administered to a nationally representative sample of 711 Iranian EFL teachers. Then, a series of focus group discussions and individual interviews with 30 teachers were carried out in the qualitative phase of the study. The findings of quantitative data analyses revealed that the Iranian EFL teachers were not willing to implement postmethod principles in their classrooms. Furthermore, the result of the content analysis for the qualitative phase indicated that Iranian EFL teachers do not implement any particular method in the strict sense of the word. Moreover, the teachers mentioned knowledge and experience of teachers; lack of adequate teacher training program; time and financial constraints of teachers; idealistic nature of postmethod; resistance of language institutes; little support of textbook developers; and cultural tradition as the impediments to the implementation of postmethod pedagogy in Iran. Finally, the theoretical and practical implications of this study are discussed.
