P-T evolution of elusive UHP eclogites from the Luotian dome How far can the thermodynamic modeling lead us?

• The NDZ is characterized by widespread anatexis that overprinted the HP/UHP metamorphism. • We present a petrologic study on two eclogites from the Luotian dome of the NDZ. • Thermodynamic modelling allowed constraining the prograde P-T evolution of the NDZ. • Unambiguous evidence of UHP conditions have not been found. • Other more suitable methods can constrain UHP history in “ really hot & slow ” terranes. paths, based on conventionalthermobarometry, follow a clockwise trajectory 27 at relatively HT ( N 750 °C) and almost none of them infer the prograde portion. 28 In this paper we present a detailed petrologic study on two eclogites from the Luotian dome of the NDZ: 29 sample 11-7c2 shows a well preserved eclogitic assemblage (Grt + Cpx + Rt), whereas sample 11-9c1 is 30 a Qtz-Ky-bearing eclogite pervasively retrogressed under granulite-facies conditions. The results of the 31 thermodynamic forward modelling allowed to constrain, for the ﬁ rst time, the prograde portion of the 32 NDZ P-T evolution; the decompression evolution at granulite-facies conditions has been also precisely 33 constrained. However, due to the HT overprinting and to poorly reactive bulk compositions, this method alone 34 is not suf ﬁ cient to reconstruct the whole P-T trajectory of the NDZ: more speci ﬁ cally, unambiguous evidence 35 of the attainment of UHP conditions have not been found. Different “ unconventional ” thermobarometric 36 methods (such asthose based on trace element and textural characterization ofzircons) might be more suitable 37 to decipher the HP/UHP history of this “ really hot and slow ” UHP terrane.
Accuracy evaluation of image-guided radiation therapy guided by optical surface monitoring system for treatment of intracranial tumors

Background: Image-guided radiation therapy (IGRT) is an advanced radiation treatment that creates an image of the tumor to guide the radiation beam during radiation therapy. Importantly, the use of ionizing radiation for daily IGRT may subject patients to an unnecessarily cumulative dose of radiation. The optical surface monitoring system (OSMS) accuracy of IGRT Materials and Methods: This retrospective analysis of prospectively collected data included 62 consecutive patients that were treated for intracranial brain tumor with IGRT guided by OSMS at the Ramathibodi Radiosurgery Center during January 2016 to December 2017. Results: A median prescribed dose of 50 Gy (range: 36-60) in 25 fractions (range: 22-30) was used. The median planning target volume was 20.65 cm 3 (range: 0.4-485). The mean set-up error measured on pretreatment cone beam computerized tomography (CBCT) and OSMS was very small (<1 mm, 1 degree) in all directions. The maximum mean difference of deviation between CBCT and OSMS was 0.29±0.17 mm in lateral direction, and 0.08±0.14° in pitch direction. Less than 5% of patients needed to be repositioned during treatment. The treatment was well-tolerated by all patients, and no severe treatment-associated toxicity was reported. Conclusion: IGRT guided by OSMS was found to be an efficacious, radiation-limiting treatment method for the management of intracranial tumors.
Comprehensive Review and Comparison of Single-Phase Grid-Tied Photovoltaic Microinverters

The power processing and the presence of the electrical isolation between the PV module and the grid is a very crucial aspect in determining the performance requirement, as well as the utility operator’s specifications for the PV microinverter design. The grid-connected PV microinverter design can be classified into four categories: 1) nonisolated single-stage topologies; 2) isolated single-stage topologies; 3) nonisolated double-stage topologies; and 4) isolated double-stage topologies. Typically, a microinverter’s performance can be enhanced by the use of nonisolated topologies to be more efficient, more compact, less bulky, and less costly than the isolated topologies. Whereas, the use of a transformer in microinverter topologies provides high-power quality as well as galvanic isolation to eliminate the safety issues, which in return meet the grid standards. The power processing (boosting the dc voltage of PV panel, extracting the maximum power and converting it to ac power), which can be achieved either via single stage or double stage, has a significant impact on the microinverter performance. This paper reviews and compares experimentally verified microinverter topologies in terms of their corresponding efficiency, power density, reliability, and cost. The most efficient topology in each category is designed and simulated in comparison with a benchmark. The topologies are then compared in terms of their component count, input voltage range, modular structure, soft-switching implementation, and battery integration.
Hearing Loss and Physical Functioning Among Adults with Heart Failure: Data from NHANES Clinical Interventions in Aging

Background: Hearing loss (HL) is associated with poor physical functioning among older adults, yet this association has not been examined in heart failure (HF), a disease in which both hearing loss and poor physical functioning are highly prevalent. We investigated whether this association exists in HF since HL represents a potentially modi ﬁ able risk factor for poor physical functioning. Methods: We studied adults aged ≥ 70 years with self-reported HF in the National Health and Nutrition Examination Survey (NHANES). HL was assessed and categorized using pure-tone averages. Activities of daily living (ADLs), instrumental ADLs (IADLs), leisure and social activities (LSA), lower extremity mobility (LEM), and general physical activity (GPA) were assessed. Multiple imputation was used to examine the association. Results: One hundred eighty-one participants comprised our population. Those with ≥ moderate HL had more dif ﬁ culty with ADLs (37.0% vs 24.0%, p=0.02), IADLs (36.0% vs 23.0%, p=0.05), and LEM (37.3% vs 20.0%, p=0.009), compared to participants with none or mild HL. In multivariable models, ≥ moderate HL was signi ﬁ cantly associated with dif ﬁ culty in physical functioning across four of the ﬁ ve domains: ADLs: PR: 1.71 (95% CI: 1.07 – 2.72); IADLs: PR: 1.71 (1.24 – 2.34); LEM: PR: 1.51 (1.01 – 2.26); and GPA: PR: 1.19 (1.00 – 1.41). Conclusion: Among older adults with HF, moderate or greater HL was associated with a higher prevalence of dif ﬁ culty with ADLs, IADLs, and LEM, compared to mild or no HL.
Enabling motions with impacts in robotic and mechatronic systems

This chapter addresses the optimal trajectory tracking problem for hybrid systems with discontinuous state trajectories. We consider state-triggered jumps in the state evolution. The tracking of a given reference trajectory is complicated by the fact that the time instants at which the closed-loop dynamics actually jumps differ from those at which the reference trajectory jumps. A recently introduced hybrid feedback tracking controller is used to cope with these differences. A method to design the corresponding time-varying feedback gains such that they minimize a cost criterion in a linear quadratic regulator (LQR) like idea is described in this chapter. The effectiveness of the proposed control law is investigated numerically by comparison with classic proportional feedback and constant gain hybrid feedback control for a mechanical system with a unilateral position constraint, namely a controlled mass interacting with a rigid obstacle. This chapter is based on: M.W. L.M. Rijnen, A. Saccon, and H. Nijmeijer. On optimal trajectory tracking for mechanical systems with unilateral constraints. In Proceedings of the 54th IEEE Conference on Decision and Control, pages 2561-2566, Osaka, Japan, December 2015. A detailed list of the differences between this chapter and the article on which it is based is provided in the Modifications chapter of this thesis. 16 Chapter 2.

Institutional Knowledge at Singapore Management University Antecedents of Consumer Trust in B-to-C Electronic Commerce

Despite the importance of trust in electronic commerce, there is insufficient theory and evidence concerning the determinants of consumer trust about an Internet vendor’s trustworthiness, and the influence of consumer trust on the consumer’s purchasing intention. The purpose of this study is to: i) develop a theoretical framework identifying the antecedents of a consumer’s trust and purchase intention, ii) test the proposed model using Structural Equation Modeling, analyzing Internet consumer behavior data collected via a Web survey, and iii) provide theoretical and managerial implications. The results of the study show that consumers’ disposition to trust, privacy protection, security protection, consumers’ perceptions about the selling party’s reputation, information quality, and system reliability are strong antecedents of consumers’ trust. Interestingly, the presence of a third-party seal did not influence consumers’ trust nor consumers’ purchase intention. Finally, consumer’s trust was a strong predictor of their purchasing intention.
Islet Transplantation from Allogenic toward Xenogeneic

Islet transplantation is a minimum invasive therapy for the treatment of unstable type 1 diabetes. In 2000, the University of Alberta group demonstrated that 7 out of 7 type 1 diabetic patients became insulin independent after islet transplantation. This protocol (the Edmonton protocol) has led the islet transplantation into clinical reality. However, several issues including necessity of multi organ donors, low efficacy of islet isolation, poor long-term islet function, and poor reproducibility among institutes became apparent. The issues have been solved with the progresses of science but the shortage of donor is still major issue. To solve the donor-shortage issue, clinical islet xenotransplantation using porcine islets has been initiated. with single donor islet transplantation [10,11]. Their first strategy two-layer pancreas preservation before two day culture of islets before transplantation anti-CD3 for Their was using anti-thymocyte globulin and daclizumab for induction immunosuppression and etanercept for anti-inflammation at the of
Character Analysis Using Space in Handwriting Image

Handwriting analysis is an effective and reliable indicator of personality and behaviour. It occurs in several stages. Initially, the handwriting samples are collected on plain paper. For better appearance, pre-processing steps such as binarization and noise removal etc are performed. First step begins with considering colour image or gray scale image as an input, then thresholding converts the image into binary image and noise removal technique is also applied. Then line segmentation, word segmentation and character segmentation are performed. After each segmentation process, normalization techniques are applied for normalization purpose to find out space between lines, words and letters in handwriting images. Finally, the mean of the space between all the closed loops formed by the characters has been found out and compared with the word spaces to determine the character. This paper focuses on efficient method of space analysis in handwritten document. The proposed method based on determination of behaviour based on space analysis. The proposed method was tested on images of IAM database which detect the exact space in between lines, words and characters before and after skew normalization of a document. The experimental result shows that proposed algorithm achieves more than 63% accuracy.
Looking for the Best, but not too Many of Them: Multi-Level and Top-k Skylines

—The problem of Skyline computation has attracted considerable research attention in the last decade. A Skyline query selects those tuples from a dataset that are optimal with respect to a set of designated preference attributes. However, the number of Skyline answers may be smaller than required by the user, who needs at least k . Given a dataset, a top-k Skyline query returns the k most interesting elements of the Skyline query based on some kind of user-deﬁned preference. That said, in some cases, not only the Pareto frontier is of interest, but also the stratum behind the Skyline to get exactly the top-k objects from a partially ordered set stratiﬁed into subsets of non-dominated tuples. In this paper we present the concept of multi-level Skylines for the computation of different strata and we discuss top-k Skyline queries in detail. Our algorithms rely on the lattice structure constructed by a Skyline query over low-cardinality domains. In addition we present external versions of our algorithms such that it is not necessary to store the complete lattice in main memory. We demonstrate through extensive experimentation on synthetic and real datasets that our algorithms can result in a signiﬁcant performance advantage over existing techniques.
Incidental Nuclear Cardiology findings in the interpretation of Myocardial SPECT Imaging

Myocardial SPECT imaging plays a crucial role in the diagnosis of coronary artery disease providing a non-invasive tool to monitor ischemia and infarction. The findings can have a profound impact in diagnosing and managing these patients. However, non-cardiac incidental findings on myocardial SPECT images can also impact the management of these patients. These non-cardiac subtleties are most often detected on the raw rotating images which are often overlooked. The intent of this pictorial essay is to illustrate several subtle non-cardiac abnormalities within nuclear cardiac imaging which can have an impact on patient management and follow-up.
Prediction of Defect in Theory of Mind According to Social and Generalized Anxiety Signs

The present study has been conducted to predict the defects of theory of mind according to social and generalized anxiety signs among university students. The study was in a kind of descriptive –correlative one, sampling method was random having screening procedure. Population included female students of Tabriz University. Among them 30 had signs of social anxiety and other 30 participants had generalized anxiety. Data gathering tools were SPIN social anxiety questionnaire and Beck anxiety questionnaire (BAI). Obtained results showed that out of two mentioned variants, social anxiety was more able to predict mind theory defect while it was not true about generalized anxiety. Therefore according to social anxiety signs among individuals, we can predict defects in mind theory.
Noether’s theorem and the Willmore functional

: Noether’s theorem and the invariances of the Willmore functional are used to derive conservation laws that are satisﬁed by the critical points of the Willmore energy subject to generic constraints. We recover in particular previous results independently obtained by R. Capovilla and J. Guven, and by T. Rivière. Several examples are considered in detail.
INVESTIGATING POSSIBILITIES OF PREDICTIVE MATHEMATICAL MODELS TO IDENTIFY AT-RISK STUDENTS IN THE SOUTH AFRICAN HIGHER EDUCATION CONTEXT

This article reports on the results of an investigation of the predictive accuracy of five different mathematical models to identify at-risk students in a Business Statistics course. Low levels of students’ success, especially in mathematics-related subjects such as statistics, are a salient problem in South Africa and other countries. Statistical knowledge is included in a variety of programmes offered by many faculties at tertiary level, and early prediction of at-risk students seems necessary to enhance academic success especially when dealing with large class groups. In this study, we used 395 Business Statistics students’ grades from an academic semester at an urban university in South Africa to build a predictive model to identify at-risk students. Grounded on Meyer’s model evaluation criteria and striving for a balance between accuracy and simplicity, two out of five models are identified as viable predictive models in identifying at-risk students by using a cross-validation test. The article shows the possibilities and limits in deriving information from a number of covariates. These results are interesting and have implications for educational practice in statistics courses.
The deviative leaks of a financial footprint in the sports world

Both fraud and corruption are a stir that lives in normal communion with the daily life of society. Because they manage to go unnoticed or because they are ignored by individuals, they feed themselves and therefore persist and gain unbearable dimensions. There are different forms of tax evasion, such as tax evasion; money laundering, such as the fraud created to ensure that illicit money enters the economic circuit cleanly; and the corruption of e-sports, which is gaining a high dimension, not only because of the problem of addiction, but also of illegal gambling and doping of sportsmen. The purpose of this article is to identify examples of sports fraud, particularly those recently publicized and more media related to the issue of tax evasion, money laundering and corruption in sports. The methodology used was the bibliographic review of articles published in scientific journals, having, in certain cases, chosen national journals of daily circulation, due to the specificity of the fraud, its actors and the way of disclosure and access of the information. It has been concluded that both fraud and sports corruption are manifested in tax evasion by those who earn the most and can use the tax havens to deceive the authorities. Money laundering is a subject whose problem is difficult for the supervisory and controlling authorities because it is difficult to detect this type of scheme. Denunciation is the most widely used and easy way to reach defrauders, but other forms of disclosure are equally important in detecting how to live beyond your means, refusing to go on vacation, etc. The case of e-sports is a more present problem than with the technological innovation and the advance of the new sports modalities also begins to be object of fraud. Not only with the doping of the players but also with the sums involved in betting this modality is having very illicit contours and that, given its maturity, it must already be fought. The lack of regulation by world sports authorities and entities creates the necessary conditions for the proliferation of the phenomenon. There is a need for worldwide re-education, higher penalties and tougher penalties for the fight against these types of fraud and corruption to take effect.
Pseudo Pipelined SAR ADC with Regenerative Amplifier

The power consumption of Analog to digital converters (ADCs) is an important design criterion in today’s market of wireless and battery operated stand alone systems. Successive approximation register (SAR) ADCs do very well in this regard and have been designed with excellent figures of merit with respect to power. However, their speeds of operation are low. Pipelined ADCs have been known to do very well where speed and performance are important criteria. There have been multiple works where combinations of the two have been used in order to leverage on the benefits of each. This work explores the different options we have in implementing the residue amplifier in a two stage pipelined ADC. A linear op-amp is traditionally used to implement the residue amplifier. Integrators have been used for this purpose as well. This design takes it one step further and explores the feasibility of using positive feedback amplification in order to achieve the function of the residue amplifier. The challenges and concepts of this new design architecture are explored. A test chip will be fabricated with this design as well and its performance in silicon will be published at a later time.
Principal Modes of Rainfall–SST Variability of the Asian Summer Monsoon: A Reassessment of the Monsoon–ENSO Relationship

Using global rainfall and sea surface temperature (SST) data for the past two decades (1979–98), the cov- ariability of the Asian summer monsoon (ASM) and El Nin˜o–Southern Oscillation (ENSO) was investigated. The ﬁndings suggest three recurring rainfall–SST coupled modes. Characterized by a pronounced biennial variability, the ﬁrst mode is associated with generally depressed rainfall over the western Paciﬁc and the ‘‘Maritime Continent,’’ stemming from the eastward shift of the Walker circulation during the growth phase of El Nin˜o. The associated SST pattern consists of an east–west SST seesaw across the Paciﬁc and another seesaw with opposite polarity over the Indian Ocean. The second mode is associated with a growing La Nin˜a, comprising mixed, regional, and basin-scale rainfall and SST variability with abnormally warm water in the vicinity of the Maritime Continent and western Paciﬁc. It possesses a pronounced low-level west Paciﬁc anticyclone (WPA) near the Philippines and exhibits large subseasonal-scale variability. The third mode is associated with regional coupled ocean–atmosphere processes in the ASM region, having spatial and temporal variabilities that suggest extratropical linkages and interhemispheric interactions occurring on decadal timescales. Results indicate the importance of regional processes in affecting ASM rainfall variability. On the average, and over the ASM region as a whole, ENSO-related basin-scale SSTs can account for about 30% of the variability, and regional processes can account for an additional 20%. In individual years and over subregions, the percentages can be much higher or lower. In addition to the shift in the Walker circulation, it is found that the regional excitation of the WPA is important in determining the rainfall variability over south Asia and east Asia. Based on the results, a hypothesis is proposed that anomalous wind forcings derived from the WPA may be instrumental in inducing a biennial modulation to natural ENSO cycles. The causes of the 1997 and 1998 rainfall anomalies over the ASM subregions are discussed in the context of these results and in light of recent observations of long-term changes in the monsoon–ENSO relationship.
A Study of the Inﬂuence of Career Counseling Perception on the Employment Competencies of Design Students in Central Taiwan

: In recent years, many advanced countries have been outsourcing their lower-skilled jobs to other countries for manufacturing. As a result, employment opportunity has been declining for younger generations in advanced countries. Moreover, the extensive application of production technologies also leads to the replacement of labors by automatic machines. The employment opportunity of young adults has also gradually been deprived. It has become more di ﬃ cult for students to make a career decision during college. After graduation, students also encounter the di ﬃ cult choice of getting a job or going to graduate school. Therefore, career counseling for a student is critical to his / her career development. It is required to assist students in developing a correct career concept so that they can make an appropriate choice for their career. College students who are studying in design-related departments in central Taiwan were selected as the research target in this study. A total of 460 questionnaire copies were dispatched and 378 valid questionnaire copies were returned with a rate of response of 82%. The result of this research is threefold, as follows. 1. Career counseling has a signiﬁcant positive inﬂuence on the vocational self-concept. 2. Vocational self-concept has a signiﬁcantly positive inﬂuence on the employment competencies. 3. Career counseling has a signiﬁcantly positive inﬂuence on employment competencies. We proposed recommendations based on the results of the investigation and analysis. It is expected that, the result can help schools provide appropriate and proper career counseling in order to assist and guide students into making proper career choices.
