Reliability, Validity, and Measurement Invariance of Attitudinal and Social Norm Factors in Math

The purpose of the present study was to provide a deeper understanding of multidimensional aspects of attitudes and social norms in educational contexts. Specifically, the current investigation aimed to (1) examine reliability and validity of factorial structure of math attitudes (Affective, Behavioral, and Cognitive factors) and perceived math social norms (Parent, Peer, and Teacher factors) and (2) test whether measurement of all factors would be invariant across national groups. Three nationally representative sample data (USA, Hong Kong, and Singapore; N = 15,019) were obtained from the 2012 Programme of International Student Assessment (PISA) database. High values in Cronbach’s Alpha, Composite Reliability scores, and factor loadings indicated strong internal consistency and convergent validity of all factors. Estimated correlations among latent factors were ranged from small to moderate in value (rs = .21 - .51, ps < .001) and each square root of average variance extracted turned out to be greater than all bivariate correlations (.71 - .85), which supported clear discriminant validity. Furthermore, the results of Multigroup Confirmatory Factor Analysis (MGCFA) yielded that measurement of the six factors was equivalent across national groups at the level of strong (scalar) factorial invariance. Implications for math education and future research are discussed.
Modeling and Classification of Cyberspace Papers Using Text Mining

The global cyberspace networks provide individuals with platforms to can interact, exchange ideas, share information, provide social support, conduct business, create artistic media, play games, engage in political discussions, and many more. The term cyberspace has become a conventional means to describe anything associated with the Internet and the diverse Internet culture. In fact, cyberspace is an umbrella term that covers all issues occurring through the interaction of information systems and humans over these networks. Deep evaluation of the scientific articles on the cyberspace domain provides concentrated knowledge and insights about major trends of the field. Text mining tools and techniques enable the practitioners and scholars to discover significant trends in a large set of internationally validated papers. This study utilizes text mining algorithms to extract, validate, and analyze 1860 scientific articles on the cyberspace domain and provides insight over the future scientific directions or cyberspace studies.
In situ measurements of atmospheric O2 and CO2 reveal an unexpected O2 signal over the tropical Atlantic Ocean

We present the first meridional transects of atmospheric O2 and CO2 over the Atlantic Ocean. We combine these measurements into the tracer atmospheric potential oxygen (APO), which is a measure of the oceanic contribution to atmospheric O2 variations. Our new in situ measurement system, deployed on board a commercial container ship during 2015, performs as well as or better than existing similar measurement systems. The data show small short‐term variability (hours to days), a step‐change corresponding to the position of the Intertropical Convergence Zone (ITCZ), and seasonal cycles that vary with latitude. In contrast to data from the Pacific Ocean and to previous modeling studies, our Atlantic Ocean APO data show no significant bulge in the tropics. This difference cannot be accounted for by interannual variability in the position of the ITCZ or the Atlantic Meridional Mode Index and appears to be a persistent feature of the Atlantic Ocean system. Modeled APO using the TM3 atmospheric transport model does exhibit a significant bulge over the Atlantic and overestimates the interhemispheric gradient in APO over the Atlantic Ocean. These results indicate that either there are inaccuracies in the oceanic flux data products in the equatorial Atlantic Ocean region, or that there are atmospheric transport inaccuracies in the model, or a combination of both. Our shipboard O2 and CO2 measurements are ongoing and will reveal the long‐term nature of equatorial APO outgassing over the Atlantic as more data become available.
Jurnal Teknologi Determination of Bahasa Melayu Word List From Friday Sermon Transcripts Using PHP and MySQL

Almost all of the speech intelligibility (SI) assessors today are from the West. The words used in the development of these SI assessors are mainly English. However, recent finding has found that word components that contribute to intelligibility of speech is different from one language to another. The purpose of this study is to determine Bahasa Melayu (BM) word list from Friday sermon transcripts. The project was undertaken by deriving BM words spoken during 52 Friday sermons read in mosques in Wilayah Persekutuan Kuala Lumpur. PHP is the programming language used to compute the frequency of words appears in the Friday sermon transcripts. These words were then stored into a database. The database used is MySQL. It has been found that the highest number of repeated word is 2509. The list is then truncated so that the numbers of repeated words range from 52 to 2509 times. The frequency of Bahasa Melayu words used in Friday sermons is an initial and important inventory that can be used in the development of SI assessor using BM words.
Real-Time RendeRing of laRge Building infoRmaTion models Current state vs . state-ofthe-art

With the use of Building Information Models (BIM), realtime 3D visualisations have become a natural tool in order to communicate ideas and share information between all involved parties in a project. Currently, several different BIM viewers are available for the purpose of interactive presentations and design reviews. However, as BIMs become larger and more detailed, it provides a challenge for available software solutions to manage them interactively. In this paper we present our findings from analysing three commonly used BIM viewers Tekla BIMsight, Autodesk Navisworks and solibri Model Viewer in terms of real-time rendering performance. In addition we have developed a prototype BIM viewer to test modern approaches for efficient real-time rendering. Specifically, we have implemented the latest version of the Coherent Hierarchical Culling algorithm. our results show that existing BIM viewers all share limitations in their ability to handle large and complex BIMs interactively. However, for the same test models, our prototype BIM viewer enables smooth realtime performance with no visual artefacts. The results from our tests thus shows that the technology to enable correct real-time rendering of large and complex BIMs is already accessible, but are currently not utilised by any of the tested BIM viewers.

Recently melamine was found to have contaminated the feed of multiple food production species leading to concern over the ability to establish an appropriate withdrawal interval and protect the safety of the food supply. To establish an appropriate withdrawal interval, a physiologically based pharmacokinetic (PBPK) model for melamine was developed for rats and extrapolated to pigs. The rat model underpredicted plasma concentrations, but better predicted tissue residues. Correlation values for plasma, kidney, and liver were 0.59, 0.76, and 0.73, respectively. The pig model underpredicted early plasma time points but had greater accuracy at later time points which is relevant to withdrawal times. Correlation (R) between predicted and observed plasma values was 0.89 with a negative intercept of 0.76. The pig model estimated a withdrawal interval (based on kidney tissue residues) of 19.2 and 20.9 h for single oral exposures of 3.0 and 5.12 mg/kg of melamine, respectively. Chronic oral dosing (3.0 and 5.12 mg/kg twice daily for 7 days) yielded withdrawal intervals of 20 and 21.3 h, respectively. PBPK models, such as this one, provide evidence of the usefulness in species extrapolation over a range of dosing scenarios and can be used to protect the food supply after accidental exposure in the face of little in the target species. 2008 Elsevier Inc.

Micropatterning of Silicon Surface by Direct Laser Interference Lithography

Direct laser interference lithography is a new and low cost technique which can generate the lineor dot-like periodic patterns over large areas. In the present work, we report on direct fabrication of micrometer structures on Si surface. In the experiments the pulsed high power Nd:YAG laser operating at 1064 nm wavelength was used. Two-beam configuration with an angle of incidence of 40◦ was employed and different laser fluences up to 2.11 J/cm were tested. Areas about 1 cm in diameter have been processed with a single pulse of 10 ns. The laser treated samples were analyzed by atomic force microscopy to investigate the surface topography and to measure the size and depth of the achieved structures. We observed periodic line-like arrays with grating period of the order of 1 μm.

Time Trend in Aboveground Biomass, Net Primary Production, and Carbon Storage of Natural Larix gmelinii Stands in Eastern Siberia

To evaluate the carbon storage and sink capacities of natural Larix gmelinii stands in eastern Siberia, aboveground biomass (AGB), aboveground net primary production (ANPP), and carbon storage in the biomass and soil organic layer were estimated in relation to stand age. The stands studied ranged from young to mature. The AGB and carbon storage in the biomass increased sigmoidally with stand age. The asymptotes of the biomass and carbon storage were 102 t'haand 51 tC·ha·, respectively. While the annual increment in the biomass was small, the carbon storage capacity of the AGB was considerable, due to the long period during which asymptotic carbon storage occurs. In addition, the carbon sink capacity of the biomass changed with stand age. The ANPP of the stands was smaller when compared with temperate and boreal stands. However, the results suggested that Siberian Larix stands functioned as carbon sinks. The deciduous leaf habit of larch species may contribute to the carbon sink capacity of the Larix stands. Carbon storage in the organic layer of soil was 80-100 % of that in the AGB, and constituted a significant carbon storage compartment.
A Method of Upgrading a Hydrostatic Model to a Nonhydrostatic Model

As the sigma-p coordinate under hydrostatic approximation can be interpreted as the mass coordinate without the hydrostatic approximation, we propose a method that upgrades a hydrostatic model to a nonhydrostatic model with relatively less effort. The method adds to the primitive equations the extra terms omitted by the hydrostatic approximation and two prognostic equations for vertical speed w and nonhydrostatic part pressure p'. With properly formulated governing equations, at each time step, the dynamic part of the model is first integrated as that for the original hydrostatic model and then nonhydrostatic contributions are added as corrections to the hydrostatic solutions. In applying physical parameterizations after the dynamic part integration, all physics packages of the original hydrostatic model can be directly used in the nonhydrostatic model, since the upgraded nonhydrostatic model shares the same vertical coordinates with the original hydrostatic model. In this way, the majority codes of the nonhydrostatic model come from the original hydrostatic model. The extra codes are only needed for the calculation additional to the primitive equations. In order to handle sound waves, we use smaller time steps in the nonhydrostatic part dynamic time integration with a split-explicit scheme for horizontal momentum and temperature and a semi-implicit scheme for w and p'. Simulations of 2-dimensional mountain waves and density flows associated with a cold bubble have been used to test the method. The idealized case tests demonstrate that the proposed method realistically simulates the nonhydrostatic effects on different atmospheric circulations that are revealed in theoretical solutions and simulations from other nonhydrostatic models. This method can be used in upgrading any global or mesoscale models from a hydrostatic to nonhydrostatic model.
Epidemics of group 16SrI-A phytoplasmas in a garden of Vilnius region in Lithuania

Abstract Here we report on a plant disease caused by insect-transmitted unculturable plant pathogenic bacteria detected in a private garden in Vilnius region. Samples of symptomatic peas (Pisum sativum L.), nasturtium (Tropaeolum majus L.), strawberry (Fragaria × ananassa Duchesne) and zucchini (Cucurbita pepo var. giromontina) plant tissues were collected. Based on the molecular technique, the Internet tools and phylogenetic analysis, these pathogens were identified as phytoplasmas and classified in phytoplasma RFLP (restriction fragment length polymorphism) group 16SrI, subgroup A. Because this pathogen may be spread by insect-vector that comes from the wild nature, the phytoplasmas could cause a problem in agriculture of Lithuania.
Organizational and task factors aimed at enhancing occupational expertise through teachers’ professional development

Abstract The study aimed to investigate the organizational and task factors as antecedents of teachers’ professional development (TPD) and occupational expertise (OE). Positivist paradigm had been used for the study. The data were collected through a structured questionnaire from a convenience sample of 233 faculty members in higher education institutions (HEIs) in Pakistan. The statistical test of correlation, descriptive, and regression were used to analyze the data. The results indicated that organizational and tasks factors and their dimensions positively and significantly affected TPD and OE. The results also found partial mediation of TPD between organizational and task factors and OE association. The results offered opportunities to administration in HEIs in Pakistan to invest in TPD to attain OE for sustained contribution in knowledge economy.
Title Scalable probabilistic similarity ranking in uncertain databases

This paper introduces a scalable approach for probabilistic top-k similarity ranking on uncertain vector data. Each uncertain object is represented by a set of vector instances that is assumed to be mutually exclusive. The objective is to rank the uncertain data according to their distance to a reference object. We propose a framework that incrementally computes for each object instance and ranking position, the probability of the object falling at that ranking position. The resulting rank probability distribution can serve as input for several state-of-the-art probabilistic ranking models. Existing approaches compute this probability distribution by applying the Poisson binomial recurrence technique of quadratic complexity. In this paper, we theoretically as well as experimentally show that our framework reduces this to a linear-time complexity while having the same memory requirements, facilitated by incremental accessing of the uncertain vector instances in increasing order of their distance to the reference object. Furthermore, we show how the output of our method can be used to apply probabilistic top-k ranking for the objects, according to different state-of-the-art definitions. We conduct an experimental evaluation on synthetic and real data, which demonstrates the efficiency of our approach.
Comparative Study of Bit Error Rate in LDPC Based OFDM System over AWGN Channels

— Modern communication systems are increasingly adopting new Morden technologies like OFDM and LDPC for achieving high performance, low Bit Error Rate (BER) and high capacity. The OFDM communication is very much inspired from the channel frequencies over the network. In such a network some kind of orthogonal distortion occurs over the channel called Inter Carrier Interference.
Polymer Light-Emitting Diodes Efficiency Dependence on Bipolar Charge Traps Concentration

The efficiency of light-emitting diodes (LEDs) based on poly[(9,9-dioctylfluorenyl-2,7-diyl)- alt-1,4-benzo- { 2, 1  -3 } -thiadiazole)], F8BT, is optimized upon simultaneous doping with a hole and an electron trapping molecule, namely, N, N  -Bis(3-methylphenyl)-N, N  -diphenylbenzidine and 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole, respectively. It is shown that, for devices with poly(3,4-ethylene dioxythiophene) doped with polystyrene sulfonic acid as hole-injection layer material and magnesium cathodes, the efficiency is nearly doubled (from ca. 2.5 to 3.7 cd/A) upon doping with ca. 0.34% by weight of both compounds.
NON-CONTACT METHODS TACTILE METHODS ROBOTIC ARMS CMMs OPTICAL

In many areas of industry, it is desirable to create geometric models of existing objects for which no such model is available. This paper reviews the process of reverse engineering of shapes. After identifying the purpose of reverse engineering and the main application areas, the most important algorithmic steps are outlined and various reconstruction strategies are presented. Pros and cons of various data acquisition techniques are described with related problems of boundary representation model construction. Specific issues addressed include characterization of geometric models and related surface representations, segmentation and surface fitting for simple and freeform shapes, multiple view combination and creating consistent and accurate B-rep models. The limitations of currently known solutions are also described, and we point out areas in which further work is required before reverse engineering of shape becomes a practical, widely-available engineering tool.
APPLYING SIMPLE SEQUENCE REPEAT (SSR) MARKER IN SCREENING FUSARIUM HEAD BLIGHT RESISTANT PARENTS

The QTL on wheat chromosome arm 3BS from Fusarium head blight (FHB) resistant cultivar Sumai 3 is a major contributor to FHB resistance. Two SSR markers (Xgwm533 and Xgwm493) have been found closely linked to the resistant QTL. This project aimed at screening FHB resistant parents used in the South Dakota spring wheat improvement program for these SSR molecular markers. This is the first step toward implementation of marker assisted selection (MAS). Fifty lines in the Fall Crossing Block (FCB00), 24 lines from the Preliminary Yield Experiment (PPY) in the year of 2000, and three FHB resistant lines with unknown pedigrees in spring wheat project, were analyzed with the SSR markers Xgwm533 and Xgwm493. Eight lines were found to possess Xgwm533, and 36 lines possess Xgwm493. This information will be applied in MAS for FHB resistance.
Ruling out critical Higgs inflation?

We consider critical Higgs inflation, namely Higgs inflation with a rising inflection point at smaller field values than those of the plateau induced by the non-minimal coupling to gravity. It has been proposed that such configuration is compatible with the present CMB observational constraints on inflation, and also with primordial black hole production accounting for the totality or a fraction of the observed dark matter. We study the model taking into account the NNLO corrections to the Higgs effective potential: such corrections are extremely important to reduce the theoretical error associated to the calculation. We find that, in the 3 sigma window for the relevant low energy parameters, which are the strong coupling and the Higgs mass (the top mass follows by requiring an inflection point), the potential at the inflection point is so large (and so is the Hubble constant during inflation) that the present bound on the tensor-to-scalar ratio is violated. The model is viable only allowing the strong coupling to take its upper 3-4 sigma value. In our opinion, this tension shows that the model of critical Higgs inflation is likely to be not viable: neither inflation nor black holes as dark matter can be originated in this version of the model.
Full-Duplex Mode in Amplify-and-Forward Relay Channels: Outage Probability and Ergodic Capacity

This paper investigates the outage probability and ergodic capacity performances for full-duplex mode in two-way amplify-and-forward relay channels. The two-way relay channels which consist of two source nodes and a single relay node working in full-duplex mode, are assumed as independent and identically distributed as Rayleigh fading. The self-interference or loop interference of the relay is unavoidably investigated for full-duplex mode. And the close-form expressions for the outage probability and ergodic capacity of full-duplex mode are derived, considering both loop interference and the coefficients of two-way relay amplify-and-forward channels. To further facilitate the performance of full-duplex mode, the half-duplex modes over different transmission time slots are analyzed. Simulation results point out the effect of loop interference on outage probability and ergodic capacity of two-way amplify-and-forward relay channels with full-duplex mode and show that full-duplex mode can achieve better performance in terms of capacity and even outperform half-duplex modes in the presence of loop interference.
International Air Travel and FDI Flows: Evidence from Barcelona

This paper provides a bridge between the literature examining the economic impact of air services and the literature analyzing the determinants of bilateral FDI flows. I estimate a gravity equation for the determinants of bilateral FDI flows between the Spanish region of Catalonia, home to the airport of Barcelona, and countries of all over the world for the period 2002–2015. I find evidence that the reduction in travel time due to the availability of nonstop flights scheduled with sufficient frequency increases the amount of FDI due to the enhanced transmission of information.
