An Active RFID Tag-Enabled Locating Approach With Multipath Effect Elimination in AGV

Automated guided vehicles (AGVs) have been largely used in manufacturing and supply chain management. With the development of Auto-ID technologies like radio frequency identification (RFID), AGVs' positioning could be enhanced. This paper demonstrates using magnetic field lines in the AGVs for precise coverage locating based on the errors' suppression positioning method. Dolph-Chebyshev antenna array is used to enable AGVs with more precise location implementation. It is observed that the far-field active RFID system positioning accuracy is higher, the movement is more stable, and the fluctuating rate is smaller.
Seeking risk or answering smart? Framing in elementary schools

This paper investigates how framing manipulations affect the quantity and quality of decisions. In a field experiment in elementary schools, 1.377 pupils are randomly assigned to one of three conditions in a multiple-choice test: (i) gain frame (Control), (ii) loss frame (Loss) and (iii) gain frame with a downward shift of the point scale (Negative). On average, pupils in both treatment groups answer significantly more questions correctly compared to the "traditional grading". This increase is driven by two different mechanisms. While pupils in the Loss Treatment increase significantly the quantity of answered questions - seek more risk - pupils in the Negative Treatment seem to increase the quality of answers - answer more accurately. Moreover, differentiating pupils by their initial ability shows that a downward shift of the point scale is superior to loss framing. High-performers increase performance in both treatment groups but motivation is significantly crowded out for low-performers only in the Loss Treatment.
Energy Aware Evaluation of LTE Hybrid-ARQ and Modulation/Coding Schemes

Mobile internet devices are among the fastest growing markets in consumer electronics. A big issue with these devices is the low battery capacity that requires the user to recharge the device regularly. This paper aims to reduce the energy consumption of LTE modems used in future devices. For this, the LTE HARQ process is modeled as a Markov chain and a simple generic model for energy consumption is introduced that divides energy consumption in a static and a dynamic part. Using these and the results of link-level simulations it is found that throughput maximization will also maximize the energy efficiency if the static energy consumption dominates. However, if the energy consumption also contains a dynamic part, the energy efficiency will severely degrade unless another optimization approach is used.
Dynamics of Crowded Vesicles: Local and Global Responses to Membrane Composition

The bacterial cell envelope is composed of a mixture of different lipids and proteins, making it an inherently complex organelle. The interactions between integral membrane proteins and lipids are crucial for their respective spatial localization within bacterial cells. We have employed microsecond timescale coarse-grained molecular dynamics simulations of vesicles of varying sizes and with a range of protein and lipid compositions, and used novel approaches to measure both local and global system dynamics, the latter based on spherical harmonics analysis. Our results suggest that both hydrophobic mismatch, enhanced by embedded membrane proteins, and curvature based sorting, due to different modes of undulation, may drive assembly in vesicular systems. Interestingly, the modes of undulation of the vesicles were found to be altered by the specific protein and lipid composition of the vesicle. Strikingly, lipid dynamics were shown to be coupled to proteins up to 6 nm from their surface, a substantially larger distance than has previously been observed, resulting in multi-layered annular rings enriched with particular types of phospholipid. Such large protein-lipid complexes may provide a mechanism for long-range communication. Given the complexity of bacterial membranes, our results suggest that subtle changes in lipid composition may have major implications for lipid and protein sorting under a curvature-based membrane-sorting model.
ON ESTIMATION OF COHERENCE IN INFLOW TURBULENCE BASED ON FIELD MEASUREMENTS

The Long-Term Inflow and Structural Test (LIST) program, managed by Sandia National Laboratories, is gathering inflow and structural response data on a modified version of the Micon 65/13 wind turbine at a site near Bushland, Texas. With the objective of establishing correlations between structural response and inflow, previous studies have employed regression and other dependency analyses to attempt to relate loads to various inflow parameters. With these inflow parameters that may thought of as single-point-in-space statistics that ignore the spatial nature of the inflow, no significant correlation was identified between load levels and any single inflow parameter or even any set of such parameters, beyond the mean and standard deviation of the hub-height horizontal wind speed. Accordingly, here, we examine spatial statistics in the measured inflow of the LIST turbine by estimating the coherence for the three turbulence components (along-wind, across-wind, and vertical). We examine coherence spectra for both lateral and vertical separations and use the available ten-minute time series of the three components at several locations. The data obtained from spatial arrays on three main towers located upwind from the test turbine as well as on two additional towers on either side of the main towers consist of 291 ten-minute records. Details regarding estimation of the coherence functions from limited data are discussed. Comparisons with standard coherence models available in the literature and provided in the IEC guidelines are also discussed.
On Projection Algorithms for Solving Convex Feasibility Problems

Due to their extraordinary utility and broad applicability in many areas of classical mathematics and modern physical sciences (most notably, computerized tomography), algorithms for solving convex feasibility problems continue to receive great attention. To unify, generalize, and review some of these algorithms, a very broad and flexible framework is investigated. Several crucial new concepts which allow a systematic discussion of questions on behaviour in general Hilbert spaces and on the quality of convergence are brought out. Numerous examples are given.
Diet-Induced Maternal Obesity Alters Insulin Signalling in Male Mice Offspring Rechallenged with a High-Fat Diet in Adulthood

Modern lifestyle has resulted in an increase in the prevalence of obesity and its comorbidities in pregnant women and the young population. It has been well established that the consumption of a high-fat diet (HFD) has many direct effects on glucose metabolism. However, it is important to assess whether maternal consumption of a HFD during critical periods of development can lead to metabolic changes in the offspring metabolism. This study evaluated the potential effects of metabolic programming on the impairment of insulin signalling in recently weaned offspring from obese dams. Additionally, we investigated if early exposure to an obesogenic environment could exacerbate the impairment of glucose metabolism in adult life in response to a HFD. Swiss female mice were fed with Standard Chow (SC) or a HFD during gestation and lactation and tissues from male offspring were analysed at d28 and d82. Offspring from obese dams had greater weight gain and higher adiposity and food intake than offspring from control dams. Furthermore, they showed impairment in insulin signalling in central and peripheral tissues, which was associated with the activation of inflammatory pathways. Adipose tissue was ultimately the most affected in adult offspring after HFD rechallenge; this may have contributed to the metabolic deregulation observed. Overall, our results suggest that diet-induced maternal obesity leads to increased susceptibility to obesity and impairment of insulin signalling in offspring in early and late life that cannot be reversed by SC consumption, but can be aggravated by HFD re-exposure.
AGN ACTIVITY AND THE MISALIGNED HOT ISM IN THE COMPACT RADIO ELLIPTICAL NGC 4278

The analysis of a deep (579 ks) Chandra ACIS pointing of the elliptical galaxy NGC 4278, which hosts a low-luminosity active galactic nucleus (AGN) and compact radio emission, allowed us to detect extended emission from hot gas out to a radius of ∼5 kpc, with 0.5–8 keV luminosity of 2.4 × 1039 erg s−1. The emission is elongated in the NE–SW direction, misaligned with respect to the stellar body, and aligned with the ionized gas and with the Spitzer IRAC 8 μm non-stellar emission. The nuclear X-ray luminosity decreased by a factor of ∼18 since the first Chandra observation in 2005, a dimming that enabled the detection of hot gas even at the position of the nucleus. The gas shows a significantly larger temperature (kT = 0.75 keV) in both the projected and deprojected profiles in the inner ∼300 pc than in the surrounding region, where it stays at ∼0.3 keV, a value lower than expected from standard gas heating assumptions. The nuclear X-ray emission is consistent with that of a low radiative efficiency accretion flow, accreting mass at a rate close to the Bondi rate; estimates of the power of the nuclear jets require that the accretion rate is not largely reduced with respect to the Bondi rate. Among possible origins for the central large hot gas temperature, such as gravitational heating from the central massive black hole and a recent AGN outburst, interaction with the nuclear jets seems more likely, especially if the latter remain confined, and heat the nuclear region frequently. The unusual hot gas distribution on the galactic scale could be due to the accreting cold gas triggering the cooling of the hot phase, a process also contributing to the observed line emission from ionized gas, and to the hot gas temperature being lower than expected; alternatively, the latter could be due to the efficiency of the Type Ia supernova heating that is lower than usually adopted.
The Fantasy Engagement Scale: A Flexible Measure of Positive and Negative Fantasy Engagement

ABSTRACT Despite the prevalence of fantasy activities in day-to-day life, there has been little systematic psychological research on fantasy. Existing work is scattered across numerous fantasy-related topics and are rarely viewed as a collective body of work. We propose a scale of fantasy engagement that addresses this scattered and often-contradictory literature by assessing both positive and negative aspects of fantasy engagement. Across four studies we develop and validate the Fantasy Engagement Scale, establishing its reliability, validity, and applicability to topics including well-being, escapism, and mental imagery. The results begin to reconcile contradictions in the existing research and have implications for future work on fantasy specifically and for studies of fantasy-related activities.
Emotional stability and conscientiousness as predictors towards job performance

The predictive validity of personality traits toward proficient job performance has always been inconsistent. Thus, the purpose of this study was to determine the predictive validity of personality traits (emotional stability and conscientiousness) on job performance. This was done by distributing 16 Personality Factor Questionnaire to 450 civil servants employees. Job performance on the other hand was measured by self-reported and annual performance evaluation report received from the employer. SEM analysis was employed to test how well conscientiousness, emotional stability and job performance model fit the sample tested. SEM results confirmed the goodness-of-fit between the model and the sample. The two constructs were also predictors of job performance. It can be implied from the findings that personality traits can be used as predictors to evaluate the suitability of job applicants in personnel decision making. Future research studies can look into other indigenous traits for measure conscientiousness and emotional stability and should investigate indirect effect on job performance.
On a generalization of the associative law

1. In my investigations in group theory, I have observed that Lagrange's theorem (that the order of a group is divisible by the order of any subgroup) does not use for its proof the Associative Law in its whole extent; this law can be replaced by a more general postulate, "Postulate A", as I shall call it. We shall represent our elements by capital italic letters; the operation upon them may be represented by a star *, so that A*B signifies the result of this operation performed upon A and B. A set of elements closed under any operation * may be called "a group"; this word is thus used in a more general sense than is usual, since the operation * is arbitrary. The ordinary groups with a special well known operation may be called "classic" to distinguish them from our generalised groups. Sets and groups will be denoted by capital German letters. POSTULATE A. In the equation
EFL Learners' Vocabulary Consolidation Strategy Use and Corresponding Performance on Vocabulary Tests.

This study describes English as a Foreign Language (EFL) learners’ use of vocabulary consolidation strategies and explores the connection between strategy use and vocabulary learning outcomes. This study included 218 participants who were students from five freshman English classes at a university in Taiwan. Students' self-reports on their use of vocabulary consolidation strategies were collected using Schmitt's (1997) taxonomy, and their lexical competence, short-term vocabulary retention, and long-term vocabulary retention were measured using a vocabulary levels test, a post-test, and a delayed recall test, respectively. The study results demonstrated that the use of more vocabulary consolidation strategies, particularly memory strategies that involved the higher-order thinking skills of analyzing, synthesizing, and organizing, was related to higher vocabulary levels. Little evidence was found with regard to the link between strategy use and short-term vocabulary retention as well as the link between strategy use and long-term vocabulary retention. The findings of this study suggest that although the positive impacts of appropriate vocabulary consolidation strategy use may not be significant and immediate, these strategies could greatly benefit learners' long-term vocabulary acquisition.
Measuring enterprise systems success: the importance of a multiple stakeholder perspective

Organisations invest enormous amount of resources in acquiring Enterprise Systems (ES), presumably expecting positive impacts to the organisation and its functions. Despite the optimistic motives, some ES projects have reported nil or detrimental impacts. This paper studies the proposition that the perspective of the stakeholders of an organisation may have contributed to the differences in receiving benefits reported in prior studies in this domain. An Enterprise System, unlike a traditional Information System (IS), entails many stakeholders ranging from top executives to data entry operators. These stakeholders (a.k.a employment cohorts) typically have multiple and often conflicting objectives and priorities and rarely agree on a set of common aims. The importance of gathering perceptions of success at multiple levels in organizations has been discussed among academics for several decades. However, there is no universal agreement on what employment cohorts should be canvassed (i.e. which are the distinctive employment cohorts? ). This paper seeks to illustrate the importance of multiple stakeholder perspective in assessing ES success by analysing 456 responses gathered from 27 public sector organizations. The alleged differences in perceptions of organisational performance are empirically measured using a prior validated model, employing four constructs and thirty-seven measures. The paper identifies three key stakeholder groups in the context of ES and highlights the importance of measuring ES success from a multiple stakeholder view point.
Race, Ethnic Drug Use, and Delinquency in Public Schools among High School 12th Graders

Research has shown a strong correlation between drug use and delinquency. In addition, research has also shown that drug use tends to peak in late adolescence and the onset of early adulthood. Consequently, the high school years, especially, the 12 th grade is an important transition in the life course of delinquents. This study used descriptive statistics to compare drug use among Black, White, and Hispanic 12 th grade high school students, and Spearman’s correlation to find which drugs have the strongest correlation to delinquency. The data for this study was downloaded from Monitoring the Future (MTF, 2007). The Null Hypothesis is that Blacks use more drugs than both Whites and Hispanics; hence they are more involved in delinquency than both Whites and Hispanics. The drugs analyzed in this study are: alcohol, marijuana, crack, cocaine, narcotics, LSD, and heroin.
From Imitation Games to Kakutani

We give a full proof of the Kakutani (1941) fixed point theorem that is brief, elementary, and based on game theoretic concepts. This proof points to a new family of algorithms for computing approximate fixed points that have advantages over simplicial subdivision methods. An imitation game is a finite two person normal form game in which the strategy spaces for the two agents are the same and the goal of the second player is to choose the same strategy as the first player. These appear in our proof, but are also interesting from other points of view.
Ageing between Gerontology and Biomedicine

Over the past two decades, public interest in the basic biological processes underlying the phenomenon of ageing has grown considerably. New developments in biotechnology and health maintenance programmes appear to be forging new relationships between biology, medicine and the lives of older people. A number of social scientists describe the process as the ‘biomedicalization of aging’. In this article, we argue that contemporary biogerontology, an important sub-field of gerontology that could be construed as the primary actor in the process of ‘biomedicalization’, should be regarded instead as advancing a critique of biomedicine. We then provide a genealogy of the critique and close the argument by pointing to sources of uncertainty within biogerontology, which should be taken into account in any further studies of the relationship between biology, medicine and the lives of older people.
Outlier-aware dictionary learning for sparse representation

Dictionary learning (DL) for sparse representation has been widely investigated during the last decade. A DL algorithm uses a training data set to learn a set of basis functions over which all training signals can be sparsely represented. In practice, training signals may contain a few outlier data, whose structures differ from those of the clean training set. The presence of these unpleasant data may heavily affect the learning performance of a DL algorithm. In this paper we propose a robust-to-outlier formulation of the DL problem. We then present an algorithm for solving the resulting problem. Experimental results on both synthetic data and image denoising demonstrate the promising robustness of our proposed problem.
TARSAL ASYMMETRY, NUTRITIONAL CONDITION, AND SURVIVAL IN WATER BOATMEN (CALLICORIXA VULNERATA)

Abstract Fluctuating asymmetry (FA) has been used as a measure of developmental stability and may indicate individual phenotypic or genotypic quality. Using water boatmen (Callicorixa vulnerata) from a natural population, we examined the relationship between tarsal FA (tarsal spine number, tarsal length) and indices of body condition in two habitats. We used body weight and residual body weight (controlling for body length) as indices of condition because experimental food deprivation in water boatmen led to a reduction in each. We detected a negative relationship between FA and both indices of condition in two ecologically distinct pond habitats. We predicted this association was due to a negative relationship between FA and competitive feeding ability. Consequently, we examined associations between survival time and tarsal FA in C. vulnerata under resource-limited laboratory conditions. Univariate analyses revealed a negative correlation between survival and tarsal FA in each trait. Inclusion of survival time, body length, gender, tarsal spine number, tarsal length, and measures of FA into multivariate analyses revealed a negative correlation between survival and FA. Individuals with the greatest survival had higher nutritional condition than individuals that succumbed early in the experiment. Asymmetric individuals may suffer a foraging handicap as a result of the use of tarsi in feeding or they may be of poor genetic quality. Our results suggest elevated FA may limit resource acquisition and are consistent with the use of FA as a measure of fitness. Corresponding Editor: D. Roff
Attentional bias to emotional facial expressions

On postule que notre equipement perceptif a ete module par l'evolution. En consequence, les stimulus et les situations menacantes pour la survie de l'espece possedent une certaine priorite dans les processus de detection, d'apprentissage et de memoire. Les expressions faciates emotionnelles menacantes ont ete etudiees dans ce contexte. Dans une serie d'experiences sur la perception visuelle de visages schematiques, presentes sur un ecran d'ordinateur, des sujets ont ete invites a detecter une expression faciale deviante parmi une foule de neuf visages. Les resultats ont mis en evidence un biais attentionnel dans la detection des visages menacants. Ainsi, un visage exprimant la colere, presente parmi des visages exprimant la joie est detecte plus vite et avec moins d'erreurs, qu'un visage exprimant la joie parmi des visages en colere. La comparaison de sujets presentant des scores eleves ou bas a des echelles de phobies sociales dans cette tâche n'a pas permis de mettre en evidence de difference dans le temps de detection, mais elle a montre que les sujets ayant un score eleve d'anxiete sociale presentaient un plus grand nombre d'erreurs.
Seven New Keck Planets Orbiting G and K Dwarfs

Planetary mass companions orbiting seven nearby G and K dwarfs have been found from the Keck Precision Doppler Survey. A "51 Peg-like" planet orbiting HD 49674 has the smallest mass yet found, M sin i = 0.12 MJ. This system does not transit. A double-planet system orbits HD 37124, with periods of 153 days and 6 yr and minimum masses of 0.91 and 1.70 MJ. Single companions with moderate eccentricity have been found orbiting HD 108874, HD 72659, HD 114729, and HD 145675 with orbital periods ranging from 1.09 to 5.98 yr, yielding minimum masses ranging from 0.90 to 4.87 MJ. Periodic Doppler velocity variations, consistent with a mildly eccentric planet in a 1 AU orbit, are reported for the chromospherically active K0 dwarf HD 128311. It remains plausible that these velocity variations are due to stellar photospheric "jitter. "
