0 M ar 2 00 2 Quantum repeated games

In a two-stage repeated classical game of prisoners' dilemma the knowledge that both players will defect in the second stage makes the players to defect in the first stage as well. We find a quantum version of this repeated game where the players decide to cooperate in the first stage while knowing that both will defect in the second.
Spotting the phenomenon of bad smells in MobileMedia product line architecture

Product line engineering a very new engineering method evolved in few past years has proven a very best technique of producing products at rapid way using the concept Reuse of assets, artifacts, and components. Software Product Lines and Software Architectures combined to form a Product Line Architecture (PLA). Many researchers have work on PLA producing different views and experiences. Architectural smells a way of accessing the PLAs, means the identification of bad smells in context of architectures formed using product line. “Why these smells occur” is briefly described and also identification has also been shown using analytical and manual analysis. These smells can be remedied but the process is too large to follow, though small systems can be easily remedied or re-factored using various techniques. Architectural smells are remedied by changing the structure and the behaviors of the internal system elements without changing the external behavior of the system. This paper describes MobileMedia Feature Model creation, Component Model creation as PLA for the assessment of Bad smells.
Adaptive Contention Resolution for VoIP Services in the IEEE 802.16 Networks

In the IEEE 802.16 networks, a subscriber station can use the contention slots to send bandwidth requests to the base station. The contention resolution mechanism is controlled by the backoff start/end values and a number of the request transmission opportunities. These parameters are set by the base station and are announced to subscriber stations in the management messages. In the case of the VoIP services, it is critical that the contention resolution occurs within the specified time interval to meet the VoIP QoS requirements. Thus, it is the responsibility of the base station to set correct contention resolution parameters to ensure the QoS requirements. This paper presents analytical calculations for the parameters that control the contention resolution process in the IEEE 802.16 WiMAX networks. The simulation results confirm the correctness of theoretical calculations. They also reveal that the adaptive parameter tuning results in a better resource utilization when compared to the static configuration. At the same time, all the delay requirements are ensured.
Efficacy Evaluation of a Multifunctional Cosmetic Formulation: The Benefits of a Combination of Active Antioxidant Substances

This study presents the association of active antioxidants substances in a multifunctional cosmetic formulation with established efficacy against signs of aging. A multifunctional cosmetic formulation containing an association of UV filters and antioxidant substances (liposoluble vitamins A, C and E, Ginkgo biloba and Phorphyra umbilicalis extracts) was evaluated. This formulation was submitted to a clinical efficacy study using biophysics techniques and skin images analysis (digital photography imaging systems, 20 MHz ultrasound, and reflectance confocal microscopy). The volunteers applied the formulation containing the UV filters and antioxidant substances during the day and the formulation with antioxidant substances and without the UV filters at night, for 90 days. The formulation increased the hydration and protected the skin barrier function after a single application. At the long term assessment the formulation provided an improvement in skin barrier function and skin hydration to the deeper layers of the epidermis, leading to an improvement in skin appearance by reducing wrinkles and skin roughness. The multifunctional cosmetic formulation studied can be suggested to preventing signs of aging and improving skin conditions. In addition, this study presents the benefits of associating different active antioxidants substances in a single cosmetic formulation to prevent skin aging.
Effects of inclusive leadership on organizational citizenship behavior: the mediating roles of organizational justice and learning culture

The aim of this article is to examine the causal relationship between inclusive leadership and employees’ organizational citizenship behavior (OCB) of Vietnam service workers. This article also examines the mediating roles of organizational justice and organizational learning culture in this causal relationship. We collected data via a questionnaire survey of a sample of 268 employees from four service firms in Vietnam. The results showed that inclusive leadership is positively related to OCB. Moreover, both organizational justice and organizational learning culture played partial mediating roles in the inclusive leadership–OCB relationship. The findings advance the literature on leadership by studying an underexplored type of leadership in relation to employee OCB. They also extend our knowledge of organizational justice and learning culture by specifying these as mediators in the mechanisms of employee inclusive leadership–OCB relations. The article thus adds to a body of work in which OCB is connected with leaders’ behavior and organizational level predictors.
A Contextual Classification Strategy for Polarity Analysis of Direct Quotations from Financial News

Quotations from financial leaders can have significant influence upon the immediate prospects of economic actors. Indiscreet or candid comments from senior business leaders have had detrimental effects upon their organizations. Established polarity classification techniques perform poorly when classifying quotations because they display a number of complex linguistic features and lack of training data. The proposed strategy segments the quotations by inferred “opinion maker” role and then applies individual polarity classification strategies to each group of the segmented quotations. This strategy demonstrates a clear advantage over applying classical classification techniques to the whole corpus of quotations. While modelling contextual information with Random Forests based on a vector of unigrams plus the “opinion maker role” reaches a maximum F-measure of 52.85%, understanding the “bias” of the quotation maker previously based on its lexical usage allows 86.23% F-measure for “unbiased” quotations and 71.10% F-measure for “biased” quotations with the Naive Bayes classifier.
Terrestrial invertebrate surveys and rapid biodiversity assessment in New Zealand: lessons from Australia

Although invertebrates play a key role in the environment, their conservation and use in environmental monitoring is often considered "too difficult" and consequently ignored. One of the main problems in dealing with invertebrates is that even limited sampling can yield large numbers of specimens and an enormous diversity of species. Other problems include the taxonomic impediment (i.e. high proportions of invertebrate taxa are undescribed and there are few specialists available to identify specimens), the lack of knowledge on species distribution, diversity and ecological roles, and the fact that invertebrates are undervalued by the general public. A number of rapid biodiversity assessment (RBA) approaches have been suggested to overcome these problems. RBA approaches generally fall into four categories: (1) restricted sampling in place of intensive sampling (sampling surrogacy); (2) the use of higher taxonomic levels than species (species surrogacy); (3) the use of recognisable taxonomic units (RTUs) identified by non-specialists (taxonomic surrogacy); and (4) the use of surrogate taxa in place of all taxa (taxon-focusing). Australia has a long history of using invertebrates in terrestrial ecological studies, and in developing and using RBA approaches. Therefore, New Zealand could benefit from the experienced gained in Australia. Potentially one of the most useful RBA approaches to take in New Zealand involves focusing resources and attention on a limited range of taxa. However, this requires substantial communication, discussion, and agreement over which taxa should be selected for conservation priorities and environmental monitoring in terrestrial ecosystems.
A wireless video transmission system using RCPT/FEC

The real-time delivery of video data over wireless is a big challenge due to the unreliable and dynamic characteristics of wireless networks, limited bandwidth and high QoS requirements for multimedia applications. According to features of wireless channels, this paper proposes a robust scheme using Rate Compatible Punctured Turbo (RCPT) codes and Forward Error Correction (FEC) parity codes for video stream distribution in wireless access environments. In the scheme, the rate of video data is adjusted based on statistics of Packet Loss Ratio (PLR) and Bit Error Ratio (BER). The RTCP feedback information to the sending end which carries bit error ratio, network packet loss ratio and transmission delay, is used to adjust the RCPT codes and FEC parity encoding. At the same time the packet video data is packed into the different size. The experiment shows that this scheme can provide more satisfied video playback quality in 3G wireless networks with different bit error ratio and packet loss ratio, and also can improve overall network utilization efficiency.
Alteration of the cytoplasmic domain of the membrane-spanning glycoprotein p62 of Semliki Forest virus does not affect its polar distribution in established lines of Madin-Darby canine kidney cells

Expression of the Semliki Forest virus p62/E2 protein was studied in the polarized epithelial cell line Madin-Darby canine kidney (MDCK). After infection this transmembrane protein, together with the other spike subunit E1, accumulates at the basolateral surface of MDCK cells (Fuller, S. D., C.-H. von Bonsdorff, and K. Simons, 1985, EMBO (Eur. Mol. Biol. Organ.) J., 4:2475-2485). The cDNAs encoding truncated forms of the protein were used to stably transform MDCK cells to examine the role of subunit oligomerization (E1-E2) and the cytoplasmic domain of p62/E2 in directed transport to the basolateral surface. The biochemical characteristics and polarity of the expressed proteins were studied using cell monolayers grown on nitrocellulose filters. A wild- type form of p62/E2, in the absence of E1, and two forms having either 15 or 3 of the wild-type 31-amino acid carboxyl cytoplasmic domain were all localized to the basolateral surface. These results indicate that the cytoplasmic domain of E2 does not contain the information essential for directed transport to the plasma membrane, and imply that this information resides in either the lumenal and/or membrane-spanning segments of this transmembrane protein.
Using game engines for marine visualisation and collaboration

Game engines at their core are modular and expandable sets of software components which allow for creation of a huge variety of different projects. Many provide the basic tools for three dimensional visualisations, networking between users, simple control schemes using keyboard and mouse or game controllers, data storage, even vocal and textual communication within the environment. While the primary purpose of these packages is for making video games for entertainment, more and more people are seeing the value of these tools in creation of more “serious” applications. These “serious games” have been focused on areas such as education and training in recent years, but there is room for expansion of game engines into the areas of visualisation and collaborative work environments. Multiplayer games are often inherently collaborative environments, forcing users to work together to reach some end goal. By using the framework provided by these games, we can more easily create a virtual workspace which can visualise real world data and problems, and allow distributed users to discuss and collaborate on potential solutions. In this paper, we discuss our development of a simple system which creates visualisations of surface current data in a 3D recreation of Galway Bay. The end goal of the system is to provide a virtual environment that will allow distributed groups of users to visualise and discuss datasets, and collaboratively come to decisions in more efficient and informed ways.
A role of uridylation pathway for blockade of let-7 microRNA biogenesis by Lin28B

The precise control of microRNA (miRNA) biosynthesis is crucial for gene regulation. Lin28A and Lin28B are selective inhibitors of biogenesis of let‐7 miRNAs involved in development and tumorigenesis. Lin28A selectively inhibits let‐7 biogenesis through cytoplasmic uridylation of precursor let‐7 by TUT4 terminal uridyl transferase and subsequent degradation by Dis3l2 exonuclease. However, a role of this uridylation pathway remains unclear in let‐7 blockade by Lin28B, a paralog of Lin28A, while Lin28B is reported to engage a distinct mechanism in the nucleus to suppress let‐7. Here we revisit a functional link between Lin28B and the uridylation pathway with a focus on let‐7 metabolism in cancer cells. Both Lin28A and Lin28B interacted with Dis3l2 in the cytoplasm, and silencing of Dis3l2 upregulated uridylated pre‐let‐7 in both Lin28A‐ and Lin28B‐expressing cancer cell lines. In addition, we found that amounts of let‐7 precursors influenced intracellular localization of Lin28B. Furthermore, we found that MCPIP1 (Zc3h12a) ribonuclease was also involved in degradation of both non‐uridylated and uridylated pre‐let‐7. Cancer transcriptome analysis showed association of expression levels of Lin28B and uridylation pathway components, TUT4 and Dis3l2, in various human cancer cells and hepatocellular carcinoma. Collectively, these results suggest that cytoplasmic uridylation pathway actively participates in blockade of let‐7 biogenesis by Lin28B.
Iris Recognition Algorithm Optimized for Hardware Implementation

Iris recognition is accepted as one of the most efficient biometric method. Implementing this method to the practical system requires the special image preprocessing where the iris feature extraction plays a crucial role. Recognition is preceeded by iris localization which consists in finding the iris boundaries as well as eyelids. In this paper the short introduction into iris localization and wavelet-based iris identification method optimized for embedded systems is described. Proposed solution was applied to high resolution images taken under near infrared light
A Fluorescent, Genetically-Encoded Voltage Probe Capable of Resolving Action Potentials

There is a pressing need in neuroscience for genetically-encoded, fluorescent voltage probes that can be targeted to specific neurons and circuits to allow study of neural activity using fluorescent imaging. We created 90 constructs in which the voltage sensing portion (S1–S4) of Ciona intestinalis voltage sensitive phosphatase (CiVSP) was fused to circularly permuted eGFP. This led to ElectricPk, a probe that is an order of magnitude faster (taus ∼1–2 ms) than any currently published fluorescent protein-based voltage probe. ElectricPk can follow the rise and fall of neuronal action potentials with a modest decrease in fluorescence intensity (∼0.7% ΔF/F). The probe has a nearly linear fluorescence/membrane potential response to both hyperpolarizing and depolarizing steps. This is the first probe based on CiVSP that captures the rapid movements of the voltage sensor, suggesting that voltage probes designed with circularly permuted fluorescent proteins may have some advantages.
LAND COVER CHANGE DETECTION USING LANDSAT TM IMAGERY OF THE 2009 VICTORIAN BUSHFIRES

The 2009 Victorian bushfires, also called the Black Saturday bushfires, ignited across the Australian state of Victoria on Saturday 7 February 2009, resulting in Australia’s highest ever loss of life from a bushfire. According to the Victorian Police, the bushfires caused at least 173 known deaths of people and 414 people injured. The use of multispectral Landsat Thematic Mapper (TM) data was able to detect and analyse the land cover changes caused by the bushfires in a rapid and cost-effective way. Many digital change detection techniques, such as image differencing and post-classification have been widely used for this purpose. The objective of this research was to quantify land cover changes by using two Landsat TM data, one pre-fire and one post-fire, acquired on 1 March 2008 and 21 April 2009, respectively, and to examine the strength and weakness of different methods. Change detection results derived from each method were assessed for accuracy against ground survey.
Stabilization of networked control systems with data packet dropout and network delays via switching system approach

An iterative approach is proposed to model networked control systems (NCSs) with arbitrary but finite data packet dropout. as switched linear systems. This enables us to apply the rich theory of switched systems to analyzing such NCSs. Sufficient conditions are presented on the stability and stabilization of NCSs with packet dropout and network delays. Stabilizing state/output feedback controllers can be constructed by using the feasible solutions of some linear matrix inequalities. The merit of the iterative approach is that the controllers can make full use of the previous information to stabilize NCSs when the current state measurements can not be transmitted by the network channel instantly. A simulation example is worked out to illustrate the effectiveness of the proposed approach.

Guidelines for the Motivational Design of Instructional Simulations

The research about effective learning resonates with this truth: in order for learners to process energetically and learn deeply, they must choose to engage (Blumenfield, Kempler, & Krajcik, 2006; Jonassen, 1988; Keller & Suzuki, 1988). Learning is an act: It requires the learner’s energy, choice, and employment of effective learning strategies. Because learning is an act—something a learner must do—motivation is fundamental. Some instructional and simulation designers avoid serious attempts to incorporate motivational design in their instructional products because of perceptions that motivation is either too vague a concept (Weiner, 1992) or lacks predictive power in respect to learning outcomes (Gagné, 1965). It is true that motivation is complex, but it is so foundational to learning that it must be thoughtfully addressed in instructional design. This article examines the unique motivational challenges and opportunities of instructional simulations and provides guidelines for their motivational design. First, let us define two key terms: instructional simulation and motivation. What is motivation? Motivation is about why people do what they do. Simply defined, it is what people desire to do, choose to do, and commit to do (Keller, 2009). It is an internal process, but can be inferred from observed choices, effort, intensity, and persistence. It is what initiates behavior, controls its intensity, maintains behavior, stops behavior, and mediates choice (Weiner, 1992). The study of motivation should also be focused on how goal-oriented activity is initiated and sustained (Ford, 1992; Schunk, Pintrich, & Meece, 2002). As previously mentioned, motivation is sometimes considered a vague concept. It is helpful to recall that the word “motivate” is a derivative of the Latin word, movere, which simply means “to move” (The Latin Dictionary, 2013). Motivation, then, in its broadest sense, is about what makes people move.
Comparison of power quality and luminous efficacy of commercial energy saving lamps in Thailand

The objectives of this paper are the investigation and comparison of the electrical power quality and efficacy of energy saving lamps. These lamps consume less real power and produce higher relative illumination compared with traditional incandescent lamps. However, the energy saving lamps produce high total harmonic distortion (THD) that have effect to power quality problem. On the other hand those lamps operate at low power factor which is the demanding additional reactive power from the electrical utility. To investigation the power quality of lamps, the samples of commercial energy saving lamps in Thailand are tested. The experimental results are compared with standard incandescent and mercury lamps. The experiments were performed by using Luminous Flux Tester which is developed according IEC standard. We found that, the sample compact fluorescent lamps have lower energy consumption, higher illumination than the standard incandescent lamps, but high level of THD. The compact fluorescent lamps have higher efficacy than the mercury lamps. In this paper, the electrical and lighting characteristics of energy saving lamps are presented to verify the effectiveness of each lamp.
Effects of Target Size and Distance on Kinematic Endpoint Prediction

Because of the ubiquity of the WIMP paradigm, many researchers seek to design new pointing facilitation techniques for Fitts-style pointing tasks. However, many of these pointing facilitation techniques make one of two simplifying assumptions: either salient targets are sparsely placed on the display, or there exists some ability to identify the endpoint, the target, of a user's movement in real time. In this paper we extend previous work on kinematic endpoint prediction (KEP), a technique that uses models of user motion to predict endpoint in Fitts-style pointing tasks. We introduce a simplified algorithm to predict user endpoint. We present a technique to measure the numerical stability of endpoint predictions in real time. We show that the distance of motion has a significant effect on predictor accuracy. Finally, we develop an accurate understanding of the relationship between movement distance and predictor accuracy and show how we can use this understanding to infer accurate, real-time probability distributions on target sets within an interface. Together, these results allow KEP to be applied in new and novel ways to pointing facilitation techniques. Author
Erroneous architecture is a relative concept

The problem this paper addresses is that an architecture formed of software components can contain composition errors (introduced, for instance, as a result of the choice of a framework’s parameters). The title “Erroneous architecture is a relative concept” is to emphasize that whether a composition error occurs in an architecture depends on the way the architecture is used in its environment. An important issue is finding a way to possibly statically verify that, for a given setup containing the architecture, no composition errors can occur in any run. The contribution of the paper is bringing an evidence that this can be done by employing behavior protocols and their consent operator.
