An Improved Deadbeat Predictive Current Control With Online Parameter Identification for Surface-Mounted PMSMs

In this article, an improved deadbeat predictive current control (DPCC) method with parameters identification for surface-mounted permanent magnet synchronous machines (SPMSMs) is proposed. With the proposed DPCC method, zero steady-state current error and deadbeat dynamic current response could be achieved, even with inaccurate initial motor parameters. On basis of the conventional DPCC method, a novel parameters identification for the stator resistance and inductance is developed, which is the main contribution of this article. The proposed parameters identification method works based on a reconstructed characteristic vector from the disturbance observer with current injection. Compared with traditional recursive-least-square methods, the proposed method can be implemented with greatly reduced computation burden. Additionally, since the design is established based on the fully discretized model, the effectiveness will be guaranteed on both low-frequency and high-frequency motors, which is a significant advantage of the proposed method.
Spatial distributions of atmospheric concentrations of radionuclides on 15 March 2011 discharged by the Fukushima Dai-Ichi Nuclear Power Plant Accident estimated from NaI(Tl) pulse height distributions measured in Ibaraki Prefecture

ABSTRACT A hybrid method for estimation of atmospheric concentrations of multiple radionuclides was developed and applied to NaI(Tl) pulse height records measured in Ibaraki Prefecture in the morning of 15 March 2011 when three radioactive plumes from the Fukushima Dai-Ichi Nuclear Power Plant Accident passed. The method is based on the simple principle for separation from deposited radionuclides’ contribution and the concentration estimation for multiple radionuclides. Difficulty in the concentration estimation due to complexity of surrounding terrains and geometry was overcome to obtain spatiotemporal variations in atmospheric concentrations of Xe-133, Te-132, I-131, I-132 and I-133 in the three plumes at 21 monitoring stations. The plume axis with higher I-131 concentration of 5.40 kBq m-3 than the previous estimations during the second plume was found in the northwestern inland area. A substantially lower Xe-133/I-131 concentration ratio of the first plume than those of the others was again recognized. The details of non-uniform spatial distribution of the radionuclide composition were found for each of the three plumes.
Syndecan‐3 enhances anabolic bone formation through WNT signaling

Osteoporosis is the most common age‐related metabolic bone disorder, which is characterized by low bone mass and deterioration in bone architecture, with a propensity to fragility fractures. The best treatment for osteoporosis relies on stimulation of osteoblasts to form new bone and restore bone structure, however, anabolic therapeutics are few and their use is time restricted. Here, we report that Syndecan‐3 increases new bone formation through enhancement of WNT signaling in osteoblasts. Young adult Sdc3−/− mice have low bone volume, reduced bone formation, increased bone marrow adipose tissue, increased bone fragility, and a blunted anabolic bone formation response to mechanical loading. This premature osteoporosis‐like phenotype of Sdc3−/− mice is due to delayed osteoblast maturation and impaired osteoblast function, with contributing increased osteoclast‐mediated bone resorption. Indeed, overexpressing Sdc3 in osteoblasts using the Col1a1 promoter rescues the low bone volume phenotype of the Sdc3−/− mice, and also increases bone volume in WT mice. Mechanistically, SDC3 enhances canonical WNT signaling in osteoblasts through stabilization of Frizzled 1, making SDC3 an attractive target for novel bone anabolic drug development.
An Analysis of the Use of the On-Campus Food Bank by International Graduate Students at the University of Guelph

AN ANALYSIS OF THE USE OF THE ON-CAMPUS FOOD BANK BY INTERNATIONAL GRADUATE STUDENTS AT THE UNIVERSITY OF GUELPH Rebecca Pereira Advisors: Dr. Elizabeth Finnis, Dr. Evan Fraser University of Guelph, 2019 In this thesis I discuss the experiences of international graduate students at the University of Guelph, who have used or are current users of the CSA on-campus food bank. This exploration illuminates the barriers that international graduate students face when coming to the University of Guelph to gain an education. In this thesis, I demonstrate factors that help shape the use of the food bank by international graduate students. I use the term “food citizenship” to explain the levels of intersectionality that international students have, and how food impacts the way that they fit into their communities. Drawing on my data, I demonstrate that food insecurity negatively impacts the wellbeing of international graduate students. I argue that, while international students are being supported by the food bank, they are still food insecure given the FAO (2012) definition of food insecurity. Consequently, I argue that the on-campus food bank is an essential resource that should be supported by the University of Guelph’s administration, but that there may be better supports that target housing, employment and student wellbeing, which can be implemented to assist international graduate students with their transition.
Experimental Study Using Cinnamon Oil for Prevention of Diabetic Nephropathy in Rats

INTRODUCTION : Diabetes mellitus causes narrowing of the small blood vessels throughout the body . It seems that the higher the blood sugar level , the more the small blood vessels narrow . As this happens , the blood vessels carry less blood , and circulation becomes poor and in turn lead to diabetic nephropathy (DN),and eye problems . Diabetes also alters fat metabolism, increasing the risk that cholesterol – laden plague will build up in the large blood vessels (1) . The most important criterion of efficiency of diabetes therapy is the effect of treatment on the widespread complications of types I diabetes mellitus. Diabetic nephropathy is one of the most prominent of these complications, and it develops in approximately 25 % 30 % of all insulin dependent diabetes mellitus patient and is accompanied with a progressive impairment of the kidney function. The pathogenesis of diabetes nephropathy is characterized by the enlargement of glomerular
Brexit means Brexit: a constructionist analysis

This paper presents a corpus-assisted discourse analysis of the Brexit means Brexit tautology from a constructionist perspective. A multimodal corpus of instances of the construction was compiled and analyzed, paying attention to the components of the construction such as its phonetic-phonological and gestural features as well as the idealized cognitive models underlying the use of the tautology in discourse. This study also addresses how different semantic-pragmatic uses have an impact on the linguistic form (e.g. prosody, gesture) and emphasizes the fluid interaction between linguistic meaning/form and the social and cultural context in which language is used. It is argued that a full understanding of any construction requires a multimodal, discourse-based analysis.
Evaluating the Outcome of Conventional Tese from Clinical Presentation in Patients with Non-Obstructive Azoospermia

Context: Several etiologies have been identified and some clinical factors might predict the probability of finding sperm in nonobstructive azoospermia (NOA). Aims: Find and correlate the clinical findings to the success of testicular sperm extraction (TESE). Settings and Design: Retrospective review of patients with NOA undergoing TESE in our department between 2012 and 2015. Methods and Material: We analyzed the sperm retrieval rate (SRR) based on testicular size, Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), total testosterone and prolactin levels as well as on the karyotype findings. We also report the results of ICSI based on clinical features. Statistical analysis used: Mann-Whitney U test; chi-square test; receiving operating characteristic and area under the curve; binary logistic regression. Results: 54 patients, mean age of 34, 57 years. The overall SRR was 51, 9%. Difference between negative and positive SRR regarding mean FSH (p=0,002) and mean LH (p=0,007) was found. No difference in SRR based on karyotype findings (p=0.127) or testicular size (p=0,336) was identified. A multivariate binary regression concluded that only FSH could be used as a predictor for TESE+. A FSH value 11,0UI/L the probability of TESE+ will be 24%. 28 patients proceeded to ICSI with clinical pregnancy and live birth rates of 20,7% and 17,2%. Conclusions: NOA patients should be fully assessed and informed about the probability of TESE+; FSH levels alone might be useful to do that. Furthermore those with normal FSH and normal testicular size can expect higher rates of sperm retrieval and live birth after ICSI.
An Urdu semantic tagger - lexicons, corpora, methods and tools

Extracting and analysing meaning-related information from natural language data has attracted the attention of researchers in various fields, such as Natural Language Processing (NLP), corpus linguistics, data sciences, etc. An important aspect of such automatic information extraction and analysis is the semantic annotation of language data using semantic annotation tool (a.k.a semantic tagger). Generally, different semantic annotation tools have been designed to carry out various levels of semantic annotations, for instance, sentiment analysis, word sense disambiguation, content analysis, semantic role labelling, etc. These semantic annotation tools identify or tag partial core semantic information of language data, moreover, they tend to be applicable only for English and other European languages. A semantic annotation tool that can annotate semantic senses of all lexical units (words) is still desirable for the Urdu language based on USAS (the UCREL Semantic Analysis System) semantic taxonomy, in order to provide comprehensive semantic analysis of Urdu language text. This research work report on the development of an Urdu semantic tagging tool and discuss challenging issues which have been faced in this Ph.D. research work. Since standard NLP pipeline tools are not widely available for Urdu, alongside the Urdu semantic tagger a suite of newly developed tools have been created: sentence tokenizer, word tokenizer and part-of-speech tagger. Results for these proposed tools are as follows: word tokenizer reports $F_1$ of 94.01\%, and accuracy of 97.21\%, sentence tokenizer shows F$_1$ of 92.59\%, and accuracy of 93.15\%, whereas, POS tagger shows an accuracy of 95.14\%. The Urdu semantic tagger incorporates semantic resources (lexicon and corpora) as well as semantic field disambiguation methods. In terms of novelty, the NLP pre-processing tools are developed either using rule-based, statistical, or hybrid techniques. Furthermore, all semantic lexicons have been developed using a novel combination of automatic or semi-automatic approaches: mapping, crowdsourcing, statistical machine translation, GIZA++, word embeddings, and named entity. A large multi-target annotated corpus is also constructed using a semi-automatic approach to test accuracy of the Urdu semantic tagger, proposed corpus is also used to train and test supervised multi-target Machine Learning classifiers. The results show that Random k-labEL Disjoint Pruned Sets and Classifier Chain multi-target classifiers outperform all other classifiers on the proposed corpus with a Hamming Loss of 0.06\% and Accuracy of 0.94\%. The best lexical coverage of 88.59\%, 99.63\%, 96.71\% and 89.63\% are obtained on several test corpora. The developed Urdu semantic tagger shows encouraging precision on the proposed test corpus of 79.47\%.
A leap forward: a user study on gestural geometry exploration*

ABSTRACT Learning mathematics can be supported by technology in various creative ways. Appliances for 3D digital setups are widely available. They have transcended their intended use as simple in- or output devices and nowadays play a part in many artistic setups. Thus, they change the way we both perceive and create (digital) models. In this paper, we examine the use of gesture-based controllers in the exploration of mathematical content. A user study was conducted as part of the scientific art and education exhibition ‘Long Night of Science’ including a control group of high school students rating physical models. The participants of the study rated the controllers or the physical models respectively by their individually felt intuitiveness and influence on the perception of the underlying mathematical content. From the answers, a connection between the intuitiveness of the controller and a positive influence on the perception of the presented mathematics is shown.
Time-delayed control of a nonlinear asymmetrical rotor near the major critical speed with flexible supports

Abstract In this study the nonlinear dynamics of an asymmetrical rotating shaft is investigated. The high-static-low dynamic stiffness are used. Also, the active time-delayed proportional derivative controller is employed to. The control signals include time delays. The effects of the proportional and derivative gains, flexible supports and added damping on the nonlinear behaviors of the system are examined. Also, the influences of the proportional and derivative gains on the critical time delays are investigated. As a result, it can be seen that a proportional derivative controller can decrease the unstable regions, and flexible supports improve the stability conditions of the system.
Indigenizing and contextualizing the use of cooperative learning strategies

Exploring the indigenous Cebuano cultural practices contextualizes a culture-based Cooperative Learning (CL) strategy. The study explored the socio-cultural background of Cebuano cooperation as reflected in the communal practices of the tagay, alayon, yayong, tambayayong, and unong (TAYTU); the process of localized cooperative learning strategies contextualized in the TAYTU; designing lesson exemplars in the TAYTU way. This qualitative study used a directive content analysis design using relevant research findings and initial codes that serve as bases of future projections, as a form of trend studies in CL strategies. The exploratory design was used to provide visualization of TAYTU exemplars. FGDs were conducted among the 60 research participants: alayon farmers (20), tambayayong fishermen (20) and male-drinkers (20), using enumeration sampling and inclusion criteria to establish the socio-cultural background of the study. The indigenous identities of the Cebuano cultural practices bridge a potential exploration of the localized and contextualized CL strategies in realizing the noble aim of malasakit in the Philippines’ AmBisyon Natin 2040. Catharsis in tagay; togetherness and unity of command in alayon; sensibility and sensitivity in yayong; sharing of extreme emotions in tambayayong; and intimacy and solidarity in unong featured a socio-cultural background necessitated in the crafting of the TAYTU Models of CL Teaching exemplars.

Gaze the Struggle of Others: The Representations of Rural Places and People of Indonesia in Tourism Media for Australian Tourists

This study contributes to understand the representations of Indonesian rural destinations in tourism media (online and offline) and the social reproduction of the on-site experiences from Australian tourists. The study analyses qualitative data from media produced between 2016 and 2018, online reviews about rural destinations, and full-day participant observations involving Australians. The findings highlight the contested representation of tranquil rice fields and the Indonesians as the exotic locals to be gaze upon for Australians. In conclusion, the framing of Indonesia for Australians expresses the unjust reproductions of tourism media to exercise the existing power relations.
Method of noun phrase detection in Ukrainian texts

Introduction. The area of natural language processing considers AI-complete tasks that cannot be solved using traditional algorithmic actions. Such tasks are commonly implemented with the usage of machine learning methodology and means of computer linguistics. One of the preprocessing tasks of a text is the search of noun phrases. The accuracy of this task has implications for the effectiveness of many other tasks in the area of natural language processing. In spite of the active development of research in the area of natural language processing, the investigation of the search for noun phrases within Ukrainian texts are still at an early stage. Results. The different methods of noun phrases detection have been analyzed. The expediency of the representation of sentences as a tree structure has been justified. The key disadvantage of many methods of noun phrase detection is the severe dependence of the effectiveness of their detection from the features of a certain language. Taking into account the unified format of sentence processing and the availability of the trained model for the building of sentence trees for Ukrainian texts, the Universal Dependency model has been chosen. The complex method of noun phrases detection in Ukrainian texts utilizing Universal Dependencies means and named-entity recognition model has been suggested. Experimental verification of the effectiveness of the suggested method on the corpus of Ukrainian news has been performed. Different metrics of method accuracy have been calculated. Conclusions. The results obtained can indicate that the suggested method can be used to find noun phrases in Ukrainian texts. An accuracy increase of the method can be made with the usage of appropriate named-entity recognition models according to a subject area.
Experiences with big data: Accounts from a data scientist’s perspective

Abstract Manufacturing has been rejuvenated by automation and digitalization. This has brought forth the new industrial era also called Industry 4.0. During the last few years, we have collaborated with companies from various industries that have all been going through this transformation. Through these collaborations, we have collected numerous examples of (sometimes troublesome) experiences with Big Data applications of production analytics. These experiences reflect the current state of production data and the challenges it poses. Our goal in this paper is to share those experiences and lessons learned in dealing with practical issues from data acquisition to data management and finally to data analytics.
Integrated laser-modulator with a universal InGaAs/InAs tunnel coupled quantum well on quantum-dot-medium

Monolithic integration of a laser diode with a modulator usually requires complicated and potentially defect-generating processing steps such as epitaxial regrowth or bonding. Alternatively, the same medium grown in a single epitaxial run can be used in both gain and electro-absorption section. We demonstrate a universal active medium with tunnel coupled InGaAs short period superlattice (SPSL) quantum well grown on InAs quantum dots (QW-on-QDs) in an AlGaAs waveguide. In this configuration, the QW serves as a tunnel injector of electrons into the QDs in the forward-biased gain section, while in the reverse-biased modulator section the InGaAs QW acts as a wavelength matched quantum Stark effect electro-absorber. The optimum QW and QD ground state separation is close to 30meV for efficient tunnel injection into QDs to increase the gain. The 3x(QW-on-QDs) double heterostructure with separate 0. 3μm waveguide was grown by molecular beam epitaxy on n-type GaAs substrate. The device was processed into two-section dies with an intermediate distributed Bragg reflector (DBR) between the sections. Focused ion beam air-gap DBR fabrication with low electrical leakage and required (~30%) optical mode reflection was employed. The laser-modulator performance with slope efficiency over 50%, 6dB power modulation, linear dynamic range>24dB at 2GHz was shown with a 200μm long modulator section and low optical feedback from the modulator to laser.
Nuclear and organelle genes based phylogeny of Dryomys (Gliridae, Rodentia, Mammalia) from Turkey

Molecular phylogeny, phylogeography and genetic structure of the genus Dryomys Thomas, 1906 from Turkey were identified by using partial sequences of intron 7 of beta fibrinogen and 12S ribosomal RNA genes and also combined data of two genes. Within Dryomys nitedula, nuclear and mitochondrial genes coherently provided a precise separation of the Thrace lineage from the other lineages in Anatolia. Contrary to this, complex and conflicted phylogenies were recovered for Anatolian populations of this species. On the other hand, the combined data of these two genes resolved mentioned complexity and incongruity and supplied a compatible and clearer phylogeny with the results of past studies for relative position of the Anatolian lineages. Thus, presence of four different lineages within D. nitedula in the localities exemplified across Turkey was confirmed. Genetic differentiations (K2P distances) between the lineages were moderate and indicated intraspecific diversity. In addition to this, genetic distance (K2P= 5.5%) between D. nitedula and Dryomys laniger was determined to be conform to the characteristic distance suggested for the separate species of mammals. Evolutionary divergence time estimations demonstrated that the probable divergence between D. laniger and D. nitedula and among its detected lineages started in the border of Late-Miocene and Pliocene and lasted to the Calabrian stage of Pleistocene in line with the previous results obtained from fossil and molecular data.
Is Institutional Common Ownership Commonly Priced? Insights from the Cost of Equity Capital

This study examines the role of institutional common owners on a firm’s cost of equity capital. Following the theoretical and empirical literature on common ownership, we hypothesize that common owners could reduce a firm’s cost of capital by reducing product market competition and improving corporate governance. Empirically, we document a negative and significant relation between common ownership and the cost of capital. We conduct difference-in-differences tests around financial institutions mergers as quasi-natural shocks to common ownership to alleviate endogeneity concerns. To shed some light on the channel, we show that the negative relation is more pronounced among firms with ex-ante predation risk. We document a decrease in firm risk in terms of product market predation risk, stock return volatility, and idiosyncratic volatility. Finally, we also document a decrease in the cost of bank loans. Overall, our findings suggest that common owners lower a firm’s cost of capital by reducing product market risk.
The Forest in the Future: A Response to Seeing the Forest for the Trees

Abstract In this commentary, we highlight some of the strengths of the bibliometric analysis conducted by Qin et al. that examines the relationships between environmental and natural resource sociologies through citation networks, coauthorship, and keyword usage. We also suggest some ways that the analysis could be expanded or built upon, and ideas for further distinct, but related, inquiry. We also reflect on our own identification, training, and mentoring within the two subfields and draw upon responses from a small purposefully selected sample of other early/mid-career environmental and natural resource sociologists to start a conversation about what the relationship between the two fields might look like in the future.
