The Effect of Relocation on Gifted Students

Over the course of two years, researchers conducted two qualitative studies to investigate the impact of moving on gifted children. Participants were five families, each of which included gifted children and at least one parent presently or recently in the military. Study 1 involved elementary students living on a military base, and students in Study 2 attended suburban high schools. While academic performance was not hindered by moving, parents and students reported that organizational inconsistencies among schools (e.g., widely varying criteria for admittance to gifted programs) were a frequent cause of frustration. Frequent relocations had little impact on parent and student perceptions of the gifted children's long-term social, emotional, and academic development. In the short term, however, certain children experienced varying degrees of social difficulties that appeared to result from the relocations.
A study on the relationship between extroversion-introversion and risk-taking in the context of second language acquisition

Two of the most examined dimensions of personality that have an affective influence on language learning are extroversion-introversion and risk-taking. In the paper we first define and look at the different studies conducted to examine the relationship between the two factors and second language acquisition (SLA). Results show that extroverts seem to take full advantage of language-use opportunities as they tend to be sociable, and are more likely to join groups, more inclined to engage in conversations both inside and outside the classroom. However, results have also concluded that a more introverted personality may be better suited to classroom learning, especially reading and writing skills. Risk takers; who are believed to be inherently extroverts, are more likely to take their existing language system to the limit. Such learners are more likely to change and more resistant to fossilization. Language proficiency is influenced directly by classroom participation which reflects, among other things, the contributing influences of risk-taking.
2–4 GHz Q-tunable LC bandpass filter with 172-dBHz peak dynamic range, resilient to +15-dBm out-of-band blocker

This paper presents a new Q-enhancement LC bandpass filter capable of 2.25~4.5 GHz frequency tuning range with independent Q control from 3 to 150. The BPF adopts both current-mode and voltage-mode drivers for more flexible operation in the intractable noise-linearity tradeoff space. A dual varactor inverse (DVI) control method is proposed to suppress varactor nonlinearity. Also, the BPF employs a dynamic negative resistance circuit that introduces a gain peaking when the filter output reaches 1-dB gain compression point, extending the P1db input power and therefore increasing the high power handling capability. The circuit is implemented in a 0.13 μm SiGe BiCMOS process. Measurement results show 9~-8 dBm of maximum IP1db, 10~18.5 dB of minimum NF, resulting in 146.5-172 dB Hz of normalized dynamic range when Q varies from 3 to 150 at fc=3.25 GHz. The BPF consumes 13-20 mA from 3.3 V supply. Chip size is 0.7×0.68 mm2.
Self-latching operation of MOBILE circuits using series-connection of RTDs and transistors

One of the most attractive features of MOBILE-based circuits is their self-latching operation, which allows pipelining at the gate level, and thus very high through-output, without any area overhead associated to the addition of the latches. However, the self-latching behavior is not inherent to the practical circuit topologies employed to implement MOBILE circuits. This paper reports on very simple MOBILE structures supporting this statement. The analysis performed is useful in extracting design guidelines to guarantee the required behavior.
The predicted crystal structure of Li4C6O6, an organic cathode material for Li-ion batteries, from first-principles multi-level computational methods

In this communication, we use first-principles based multi-level computational methods to predict the crystal structure of Li4C6O6, the key intermediate material that can be oxidized to Li2C6O6 or reduced to Li6C6O6. This predicted structure leads to an X-ray diffraction (XRD) pattern in good agreement with experiment, validating the predicted structure. With this structure in hand one can proceed to determine details for the electrochemical properties of these organic electrodes (chemical potential for Li ion as a function of loading and the mechanism for the lithiation/delithiation process) useful in designing optimum systems.
Application of the Kirchhoff Transform to Thermal Spreading Problems With Convection Boundary Conditions

Thermal management and thermal analysis of microelectronic devices and packages are critical in ensuring the performance, reliability, and lifetime of today's electronic systems. When the thermal conductivity of a semiconductor or packaging material depends strongly on temperature, the use of a constant thermal conductivity value may significantly underestimate the temperature rise and thermal resistance. The Kirchhoff transform provides a convenient way of linearizing the heat conduction equation to use computationally efficient analytical solutions to calculate the device or package temperature. In the past, the application of the Kirchhoff transform has been restricted to temperature and heat flux boundary conditions in thermal spreading problems. In this paper, we developed an approximate solution for the application of the Kirchhoff transform to thermal spreading problems with convection in the sink plane and show the technique to be accurate to within 1% for relevant problems in device-level thermal analysis. The proposed technique is combined with a recently developed analytical solution for temperature rise in complex, multilayered structures in which a finite heat transfer coefficient in the sink plane needs to be considered. These analytical expressions and the Kirchhoff transform are valuable tools for accurately predicting the temperature in high-power, wide bandgap electronics, such as gallium nitride power amplifiers.
Reinforcement Sensitivity and Responsiveness to Performance Feedback: A Preliminary Investigation

Variability in responsiveness to academic interventions is a common phenomenon in school psychology practice, but the variables associated with this responsiveness are not well understood. Reinforcement sensitivity, a generalized tendency to learn quickly in reward contingency situations, is one variable for increased understanding. In the present study, teachers completed a rating scale measuring their students’ sensitivity to reinforcement. The students then participated in a classwide performance feedback intervention in the domain of mathematics. The rating scale was found to be reliable and predicted students’ responsiveness to the intervention. Implications for future research on reinforcement sensitivity and responsiveness to intervention assessment strategies are discussed.
GRAPHICAL USER INTERFACE WITH APPLICATIONS IN SUSCEPTIBLE-INFECTIOUS-SUSCEPTIBLE MODELS.

UNLABELLED Practical significance of understanding the dynamics and evolution of infectious diseases increases continuously in contemporary world. The mathematical study of the dynamics of infectious diseases has a long history. AIM By incorporating statistical methods and computer-based simulations in dynamic epidemiological models, it could be possible for modeling methods and theoretical analyses to be more realistic and reliable, allowing a more detailed understanding of the rules governing epidemic spreading. MATERIAL AND METHODS To provide the basis for a disease transmission, the population of a region is often divided into various compartments, and the model governing their relation is called the compartmental model. To present all of the information available, a graphical user interface provides icons and visual indicators. The graphical interface shown in this paper is performed using the MATLAB software ver. 7.6. 0. MATLAB software offers a wide range of techniques by which data can be displayed graphically. The process of data viewing involves a series of operations. To achieve it, I had to make three separate files, one for defining the mathematical model and two for the interface itself. RESULTS Considering a fixed population, it is observed that the number of susceptible individuals diminishes along with an increase in the number of infectious individuals so that in about ten days the number of individuals infected and susceptible, respectively, has the same value. If the epidemic is not controlled, it will continue for an indefinite period of time. By changing the global parameters specific of the SIS model, a more rapid increase of infectious individuals is noted. CONCLUSIONS Using the graphical user interface shown in this paper helps achieving a much easier interaction with the computer, simplifying the structure of complex instructions by using icons and menus, and, in particular, programs and files are much easier to organize. Some numerical simulations have been presented to illustrate theoretical analysis.
Complete hardware / software solution for implementing the control of the electrical machines with programmable logic circuits

In this paper authors propose a rapid and new method to design and optimize the electric motor control using field programmable gate array (FPGA). The elaborated designing algorithm takes advantage of the unification of ISE Xilinx digital designing environment with Matlab/Simulink simulation and testing environment, through system generator toolbox. This results in a faster and efficient design flow. A software and hardware operational system was realized using programmable logic circuits to control a brushless DC (BLDC) motor. The system is able to operate independently or to communicate bidirectional and in real time with Matlab/Simulink environment. A hierarchical control system design method is achieved too, based on parameterized models; system generator toolbox library is extended with specific electric motors control blocks (PWM, PID, commutation blocks, etc).
Sex in Advertising: A Comparison of 1964 and 1984 Magazine Advertisements

Abstract This study presents a content analysis of sexual portrayals in magazine advertisements during 1964 and 1984. The results show that the percentage of ads with sexual content did not increase over the twenty-year period, but that the types of sexual portrayals did; sexual illustrations became more overt; and there was a greater reliance on visual than verbal sex in 1984 than 1964. The study also found that female models are more likely to be portrayed as sexually clad, partially clad or nude than were male models.
FDR 2.0: A Low-Power Dynamically Reconfigurable Architecture and Its FinFET Implementation

Large area/delay/power overheads are required to support the reconfigurability of field-programmable gate arrays (FPGAs). We proposed a hybrid CMOS/nanotechnology dynamically reconfigurable architecture, called NATURE, earlier to address this challenge. It uses the concept of temporal logic folding and fine-grain (i.e., cycle-level) dynamic reconfiguration to increase logic density and save area. Because logic folding reduces area significantly, most of the on-chip communications become localized. To take full advantage of localized communications, we then presented a new CMOS-based fine-grain dynamically reconfigurable (FDR) architecture. It consists of an array of homogeneous logic elements (LEs), which can be configured into logic or interconnect or a combination of both. FDR eliminates most of the long-distance and global wires, which occupy a large amount of area in conventional FPGAs. FDR improves the area-delay product by an order of magnitude relative to conventional architectures. In this paper, we present an augmented FDR 2.0 architecture, where: 1) the LE is augmented with dedicated carry logic to facilitate arithmetic operations; 2) diagonal direct links are incorporated to improve the flexibility of local communication; and 3) coarse-grain blocks, including embedded memories and digital signal processing (DSP) blocks, are added to support fast data-intensive computations. Experimental results show that the coarse-grain design can improve circuit performance by 3.6× compared with the fine-grain FDR architecture. Incorporation of the DSP blocks in FDR 2.0 also enables more effective area-delay and power-delay tradeoffs, allowing the users to trade performance for smaller area or power consumption. We have implemented the design in the 22-nm FinFET technology, which enables more flexible and effective power management. Finally, different types of FinFETs and power management techniques have been explored in FDR 2.0 to optimize power.
Detection of Illegal Players in Massively Multiplayer Online Role Playing Game by Classification Algorithms

Online games have become one of the most popular games in recent years. However, fraud such as real money trading and the use of game bot, has also increased accordingly. In order to maintain a balance in the virtual world, the operators of online games have taken a stern response to the players who conduct fraud. In this study, we have sorted out players' behaviors based on players' game playing time in order to support and find potentially illegal players in the MMORPG. In this paper, we added a topic model to the experiment and used k-means as a major tool to classify the players in the World of War craft Avatar History Dataset and find potentially illegal players.

Topological formulation of discrete-time switched linear systems and almost sure stability

In this paper, we study the stability of discrete-time switched linear systems via symbolic topology formulation and the multiplicative ergodic theorem. A sufficient and necessary condition for ¿A-almost sure stability is derived, where ¿A is the Parry measure of the topological Markov chain with a prescribed transition (0,1)-matrix A. The obtained ¿A-almost sure stability is invariant under small perturbations of the system. The topological description of stable processes of switched linear systems in terms of Hausdorff dimension is given, and it is shown that our approach captures the maximal set of stable processes for linear switched systems. The obtained results cover the stochastic Markov jump linear systems, where the measure is the natural Markov measure defined by the transition probability matrix.
Selection of time series forecasting models based on performance information

In this work, we proposed to use the Zoomed Ranking approach to rank and select time series models. Zoomed Ranking, originally proposed to generate a ranking of candidate algorithms, is employed to solve a given classification problem based on performance information from previous problems. The problem of model selection in Zoomed Ranking was solved in two distinct phases. In the first phase, we selected a subset of problems from the instances base that were similar to the new problem at hand. This selection is made using the k-Nearest Neighbor algorithm, whose distance function uses the characteristics of the series. In the second phase, the ranking of candidate models was generated based on performance information (accuracy and execution time) of the models in the series selected from the previous phase. Our experiments using the Zoomed Ranking revealed encouraging results.
Generation of Hypotheses in Wason's 2–4–6 Task: an Information Theory Approach

We explored the “context of discovery” in Wason's 2–4–6 task, focusing on how the first hypothesis is generated. According to Oaksford and Chater (1994a) people generate hypotheses extracting “common features”, or regularities, from the available triples, but their model does not explain why some regularities contribute to the hypothesis more than do other regularities. Our conjecture is that some regularities contribute to the hypothesis more than do other regularities because people estimate the amount of information in the perceived regularities and try to preserve as much information as possible in their initial hypotheses. Experiment 1, which used two initial triples, showed that the presence of high-information relational regularities in the initial triples affected the information in the initial hypotheses more than did the presence of low-information object regularities. Experiment 2 extended the results to the classic situation in which only one initial triple is given. It also suggested that amount of information is the only aspect of the structure of the triple that affects hypotheses generation. Experiment 3 confirmed the latter finding: Although relations are commonly distinguished between first-order and higher order relations, the latter being most important for generating hypotheses (Gentner, 1983), higher order relations do have an effect on Wason's 2–4–6 task only if their presence increases information. In the conclusion we discuss the statistical soundness of human hypotheses generation processes, and we ask an unanswered question: Amount of information explains why some regularities are preferred to others, but only within a set of “nonarbitrary” regularities; there are object regularities that are rich in information content, but are considered “arbitrary”, and are not used in generating hypotheses. Which formal property can distinguish between these two sets of regularities?
Association of Left Atrial Spontaneous Echo Contrast to Uric Acid in Patients with Mitral Stenosis

Spontaneous echo contrast (SEC) is the presence of smoke‐like echoes with a characteristic swirling motion of the blood in echocardiography. Previous clinical studies have shown that SEC is a risk factor for left atrial thrombus formation and a predictor of potential systemic embolism originating from the heart. There is an association between uric acid and prothrombotic state. Therefore, we aimed to investigate the role of uric acid in SEC in patients with mitral stenosis (MS).
Homogeneous dielectric barrier discharge in nitrogen at atmospheric pressure

A dielectric barrier discharge in nitrogen at atmospheric pressure was investigated by means of the electrical measurement, the fast photography and the time-resolved spectroscopy. By addition of a nitrogen flow, a stable homogeneous discharge was produced in a gap not longer than 3 mm and it was identified with a Townsend discharge. It was found that the discharge was extinguished while the voltage of the gas gap continued to increase. This extraordinary manner of discharge extinction was explained by the limited number of trapped electrons on the dielectric surface that could not provide a long-lasting Townsend discharge with sufficient secondary electrons. Due to the ‘memory effects’ the lowest breakdown voltage for a Townsend discharge in a 2 mm gap is only 4.9 kV in contrast to the streamer breakdown voltage of 8.2 kV. The working domain of the Townsend discharge is dependent on the frequency and the amplitude of the applied voltage. When the flow velocity increases from 0 to 140 cm s−1, the discharge current decreases from 2.9 to 2.3 mA and the breakdown voltage increases from 5.3 to 5.9 kV, which is attributed to the nitrogen pressure in the gap increasing with the flow velocity. With the gas flow, the intensities of the spectral lines from the second positive system of N2 are almost unchanged, whereas those from NOγ systems are significantly reduced. From this phenomenon, it may be inferred that the density of oxygen as impurity in the discharge gap decreases with the gas flow. This result is in agreement with the existing theory that less oxygen leads to more metastables N2(A) surviving to produce more seed electrons for initiating a Townsend discharge in nitrogen at atmospheric pressure.
Interventions for Grandmothers: Comparative Effectiveness of Resourcefulness Training, HRV Biofeedback, and Journaling

In the United States, more than one million grandmothers are raising their grandchildren, and this can be stressful, produce depressive symptoms, and adversely affect their quality of life. The pilot trial of 60 grandmothers reported here examined the effects of a cognitive behavioral intervention (resourcefulness training), biofeedback control training (focused on heart rate variability), and journaling on measures of perceived stress, depressive symptoms, and quality of life. Comparative analysis revealed a decrease in stress with all three conditions; a decrease in depressive symptoms in the resourcefulness training group; and improved quality of life in the resourcefulness training and biofeedback groups.
Genetic effects of released swimming crab (Portunus trituberculatus) on wild populations inferred from mitochondrial control region sequences

Abstract Along the coast of Shandong Province in China, an extensive hatchery-release programme has been conducted for more than 10 years. However, no information has been reported concerning the long-term effects on the wild population resulting from the release of large numbers of juveniles in Portunus trituberculatus. In this study, sequence variation of swimming crab P. trituberculatus based on the mitochondrial control region was investigated for 946 swimming crabs at the releasing sites from 2012 to 2014. The result showed that the wild P. trituberculatus was characterized by high genetic diversity indices, and not significantly different from the previous study. Low FST values were estimated among the groups of different years and different sites, which suggested no genetic differentiation found in the wild population after the stock enhancement programme. Hence, the long-term extensive hatchery release programme has not affected the genetic structure of wild P. trituberculatus populations along the coast of Shandong Province.
Stabilization of actin filaments prevents germinal vesicle breakdown and affects microtubule organization in Xenopus oocytes

In Xenopus oocytes, extremely giant nuclei, termed germinal vesicles, contain a large amount of actin filaments most likely for mechanical integrity. Here, we show that microinjection of phalloidin, an F‐actin‐stabilizing drug, prevents the germinal vesicle breakdown (GVBD) in oocytes treated with progesterone. These nuclei remained for more 12 h after control oocytes underwent GVBD. Immunostaining showed significant elevation of actin in the remaining nuclei and many actin filament bundles in the cytoplasm. Furthermore, microtubules formed unusual structures in both nuclei and cytoplasm of phalloidin‐injected oocytes stimulated by progesterone. Cytoplasmic microtubule arrays and intranuclear microtubules initially formed in phalloidin‐injected oocytes as control oocytes exhibited white maturation spots; these structures gradually disappeared and finally converged upon intranuclear short bundles when control oocytes completed maturation. In contrast, treatment of oocytes with jasplakinolide, a cell membrane‐permeable actin filament‐stabilizing drug, did not affect GVBD. This drug preferentially induced accumulation of actin filaments at the cortex without any increase in cytoplasmic actin staining. Based on these results, intranuclear and cytoplasmic actin filament dynamics appear to be required for the completion of GVBD and critically involved in the regulation of microtubule assembly during oocyte maturation in Xenopus laevis. © 2012 Wiley Periodicals, Inc
