Mobile cloud middleware : Towards selective cloud services based on location of users

Due to the advancement of cloud computing, mobile technologies are growing at a very high pace since cloud platforms provide their own resources to meet the needs of mobile users. However, the combination of cloud computing and mobile computing is created not only to consume remote services, extend the capabilities of mobile devices or profit from all the massive advantages of the cloud computing, but also to enable mobile users to exploit context information provided by their smartphones. Hence, context-aware systems offer entirely new opportunities for mobile cloud applications by means of collecting mobile users’ context data and adopting cloud services’ behaviors accordingly. In the previous paper [1], we introduced the detailed architecture for a middleware system, which can define a new interaction between a mobile client and different cloud providers. The current paper is an extension of the earlier one describing an improved version of the proposed middleware, which exploits available cloud resources as well as mobile users’ locations to better finding effective mechanisms to consume the right and light cloud services. We conduct experiments using cloudAnalyst to prove the feasibility of our proposed architecture.
An Implicit Matrix-Free Discontinuous Galerkin Solver for Turbulent Flows

This paper presents some recent advancements of the computational efficiency of a Discontinuous Galerkin (DG) solver for the Navier-Stokes (NS) and RANS (Reynolds Averaged Navier Stokes) equations. The implementation and the performances of a Newton-Krylov matrixfree method is presented and discussed. The solutions of the viscous flow around a Naca 0012 airfoil (M∞ = 0.5, α = 2◦, Re = 500) and the turbulent flow around the L1T2 3-element airfoil (M∞ = 0.197, α = 20.18, Re = 3.52 · 10) have been used to asses the algorithm.
Targeting of gp 78 for ubiquitin-mediated proteasomal degradation by Hrd 1 : cross-talk between E 3 s in the endoplasmic reticulum

There are an increasing number of ubiquitin ligases (E3s) implicated in endoplasmic reticulum (ER)-associated degradation (ERAD) in mammals. The two for which the greatest amount of information exists are the RING finger proteins gp78 and Hrd1, which are the structural orthologs of the yeast ERAD E3 Hrd1p. We now report that Hrd1 targets gp78 for proteasomal degradation independent of the ubiquitin ligase activity of gp78. The significance of this is underscored by the diminished level of a gp78-specific substrate, Insig-1, when Hrd1 expression is decreased and gp78 levels are consequently increased. These finding demonstrate a previously unappreciated level of complexity of the ubiquitin system in ERAD and have potentially important ramifications for processes where gp78 is implicated including regulation of lipid metabolism, metastasis, cystic fibrosis and neurodegenerative disorders.
In Vitro Culturing of Mycorrhiza and Mycorrhiza Like Fungi

Arbuscular mycorrhizal (AM) fungi exist in rhizosphere of several vascular plants and have important roles in sustainable agriculture as well as agricultural ecosystems management. These fungi could be able to colonize host plants by their three sources including spores, mycorrhizal roots and extraradical mycelia. There are obvious differences among fungal families and genera in life cycle and ecology. Fungi in Glomeraceae and Acaulosporaceae families could be able to colonize host plants by 3 mentioned sources while in Gigasporaceae, the only inoculum sources are spores. Spore formation depended on different factors such as seasonality, nutrient levels as well as interaction with other soil microorganisms. There are so many efforts in order to get pure isolates of arbuscular mycorrhizal fungi but most of them faced to problems and failed due to biotrophic nature of these fungi. In vitro culturing of these fungi is very important especially for studying on host plant growth and taxonomic studies. First time, Mosse used toot tissue culture method for obtaining pure culture. Also, in vitro culturing of AM fungal species using carrot (Daucus carota L.) transformed hairy roots by Ri plasmid of Agrobacterium rhizogenes (Ricker) Conn. is also another method. Using this method, several fungal species could be propagated in vitro such as Gigaspora margarita, G. gigantea, Rhizophagus fasciculatus, Rhizophagus intraradices, Diversispora versiformis and Funneliformis caledonium. Using this method, it could be possible to study on molecular as well as biochemical aspects of arbuscular mycorrhizal symbiosis. Unfortunately, there have not been studies on in vitro culturing of these fungi isolated from rhizosphere. The main purpose of this study is possibility of in vitro culturing of most prevalent mycorrhiza and mycorrhiza like fungi using transformed hairy roots system as well as study on fungal life cycle under laboratory conditions.
Damage detection method for composites based on laser vibrometer

This paper contains results of research in the topic of damage detection based on propagation of elastic waves. Elastic waves that propagate in thin-walled structures are called Lamb wave or guided waves. Their propagation follows the structure curvature. These waves interact with discontinuities (rivets, holes, thickness change, damage) within the structural element. After registering the wave propagation in the form of time signals the information contained in the signals can be efficiently used for damage detection. In reported research authors used a method based on a piezoelectric transducer for wave excitation and a laser vibrometer for wave sensing. The method was tested on different CFRP (Carbon Fibers Reinforced Polymer) composite samples. The damage in composite sample was introduced thanks to laser shocks. Indeed, the high power laser irradiation of a composite surface results in a shock wave propagation into the composite target. These shock waves generate tension inside the target, which could damage or not the material depending on the laser parameters. Therefore, the laser parameters were adjusted to create different levels of damage inside the composite samples. Various locations and number of defects in the samples were considered. This allowed to study the influence of damage severity on the investigated NDT method. The results showed that the damage position can be indicated by the proposed method. However in the case of multiple defects, the results are influenced by the distance from the wave source to damage. It does matter if a wave has to travel through one damaged region in order to reach the other damaged region.
Comparing Focus on Form and Focus on FormS in Second-Language Vocabulary Learning

<p>The study compares the effectiveness of Focus on Form (FonF) and Focus on FormS (FonFs) approaches in learning new L2 words by 158 high-school learners of English as L2. In phase 1 of the study, the FonF group read a text containing the target words, discussed it in small groups, and answered comprehension questions. The FonFs group studied the target words as discrete items with their meanings and examples of usage. In phase 2 of the study, all learners received the target words with their meanings and studied them for 15 minutes for a quiz. They were tested immediately after each phase, and two weeks later. </p><p>Results revealed significantly higher scores for FonFs group after phase 1, but the difference disappeared after phase 2. As learners cannot be expected to study all vocabulary for tests, form-focused instruction – and particularly FonFs – is claimed to be indispensable for L2 vocabulary learning. </p><p>L'efficacité des approches centrées sur la forme (CF) a été comparée à celle des approches centrées sur les formeS (CFS) pour l'apprentissage de nouveaux mots dans une langue seconde, au cours d'une étude comptant 158 étudiants de niveau secondaire apprenant l'anglais comme langue seconde. Pour la phase 1, le groupe CF a lu un texte contenant les mots ciblés, en a discuté en petits groupes et a répondu à des questions de compréhension. Le groupe CFS a étudié les mots ciblés en tant qu'éléments distincts avec leurs significations et des exemples d'usage. Pour la phase 2, tous les apprenants ont reçu les mots ciblés et leurs significations, et ils les ont étudiés pendant 15 minutes pour un examen. Ils ont été évalués immédiatement après chaque phase, puis deux semaines plus tard. Les résultats ont révélé des scores notablement plus élevés dans le groupe CFS après la phase 1, mais cette différence avait disparu après la phase 2. Comme on ne peut s'attendre à ce que les apprenants étudient tout le vocabulaire pour les examens, une approche centrée sur la forme, en particulier CFS, serait indispensable aux personnes qui apprennent le vocabulaire d'une langue seconde. </p>
Moral Conviction 1 Running Head : MORAL CONVICTION In the Mind of the Perceiver : Psychological Implications of Moral Conviction

Moral conviction is a subjective assessment that one’s attitude about a specific issue or situation is associated with one’s core moral beliefs and fundamental sense of right or wrong. A growing body of research demonstrates that level of moral conviction reliably predicts changes in the way people think, feel, and act in situations, irrespective of whether that situation fits normative definitions of morality. Therefore, it is important to measure whether and how much individuals perceive a given situation to be moral rather than assert that a situation is moral based on philosophical criteria. This chapter compares and contrasts moral conviction and moral judgment research and argues that both approaches are necessary to develop a complete science of morality.

Advancement in Electrochemical DNA Biosensors for GMO Detection : A Review Study

Article type: Review Article Genetically modified organisms (GMOs) are plants or animals whose genetic composition has been transformed using recombinant DNA technology. This technology has various new features, such as resistance to herbicides, viruses, and insects. Recently, genetic modification of food products has increased in order to reduce poverty and hunger across the world and increase food production. However, the impact of GMOs on human health is a growing concern worldwide. Due to the increased global production of GMOs, the presence of these agents in food products needs to be monitored, which has recently attracted the attention of many researchers in order to develop rapid, simple, accurate, and sensitive detection methods for these products. Electrochemical DNA biosensors are among the quickest methods that have been extensively studied due to their high sensitivity, cost-efficiency, rapid reaction, and applicability in aqueous solutions. The present study aimed to review the studies focused on the detection of GMO based on electrochemical biosensors. Article History: Received: 20 Aug 2018 Accepted: 27 Dec 2018 Published: 12 Feb 2019
On Scrambling: A Reply to Boskovic and Takahashi

In this article I argue against Bošković and Takahashi’s (1998) analysis of scrambling as base generation (with lowering for Ā-cases). I present evidence from Russian of scope and antireconstruction effects and scrambling/wh-movement parallels, all implicating a ‘‘classical’’ overt movement account of Ā-scrambling. I then discuss theoretical issues unresolved by the base generation/lowering account. Having shown that Ā-scrambling is (upward) movement, I argue that the account of A-scrambled arguments as base-generated also loses its force. In conclusion I suggest an alternative way to eliminate the apparent optionality associated with scrambling, while maintaining the classical analysis of scrambling as upward movement.
Treatment patterns, survival and economic outcomes in Medicare-enrolled, older patients with HR+/HER2− metastatic breast cancer

Abstract Background: Endocrine therapy (ET) remains a foundation of systemic therapy for HR+/ HER2− metastatic breast cancer (MBC), although chemotherapy (CT) is used in select patients. In this “real-world” study, we explored treatment patterns, health care resource use (HCRU), costs, adverse events (AEs) and overall survival (OS) in Medicare-enrolled, older patients with HR+/HER2− MBC. Methods: Patients with HR+/HER2− MBC (2007–2011) and aged >66 years were retrospectively analyzed using the SEER–Medicare data. Treatment patterns, HCRU, costs, AEs and OS after MBC diagnosis through end of study period (31 December 2013) were examined using descriptive and multivariable analyses. Results: Among 3622 eligible patients, ET was the most common treatment (77%), followed by CT (50%), radiation (48%) and surgery (19%). The proportion of patients treated with ET monotherapy decreased across therapy lines, from 74% in first line (1 L) to 35% in 4 L. The total number of unique therapy regimens used was 181 in 1 L, 171 in 2 L, 128 in 3 L, and 95 in 4 L. The median OS from MBC diagnosis was 25.3 months (95% CI, 24.0–26.7). In multivariable analyses, receipt of CT and combination CT + ET (versus ET monotherapy) in 1 L, metastatic disease at initial diagnosis, larger tumor size, and presence of visceral and brain metastases at MBC diagnosis significantly predicted receipt of 2 L therapy. Conclusions: ET was the most common first-line treatment for study patients, but its use decreased gradually in the subsequent lines. The heterogeneity in the treatment selection highlights a lack of consensus for the management of HR+/HER2− MBC in routine practice.
University of Groningen Discrete approximations to vector spin models

We strengthen a result from Külske and Opoku (2008 Electron. J. Probab. 13 1307–44) on the existence of effective interactions for discretized continuous-spin models. We also point out that such an interaction cannot exist at very low temperatures. Moreover, we compare two ways of discretizing continuous-spin models, and show that except for very low temperatures, they behave similarly in two dimensions. We also discuss some possibilities in higher dimensions. PACS numbers: 05.50. +q, 75.10. Hk Mathematics Subject Classification: 82B20, 82B26, 60K35
Observations on the use of canonical momenta in an efficient recursive algorithm for the forward dynamics of open-loop multibody systems

A new method for establishing the equations of motion of multibody mechanisms based on canonical momenta is introduced in this paper. In absence of constraints, the proposed forward dynamics formulation results in a Hamiltonian set of 2n first order ODE’s in the generalized coordinates q and the canonical momenta p. These Hamiltonian equations are derived from a recursive Newton-Euler formulation. It is shown how in the case of a serial structure with general joints, an O(n) formulation is obtained. The amount of required arithmetical operations is considerably less than comparable acceleration based formulations. Keywords— Hamilton’s equations, canonical momenta, recursive formulation
Partnership, Knowledge Translation, and Substance Abuse Prevention With a First Nations Community

The Alexis Nakota Sioux Nation, a member of the Treaty Six agreement with Canada, has a population of approximately 1,600 and is located in Central Alberta, Canada. The community has a kindergarten through 12th-grade school with just over 200 students. In 2002, Dr. Lola Baydala, a pediatrician motivated by a desire to better understand the unique health issues of First Nations youth and families, approached the Alexis Nakota Sioux Nation and offered to conduct school-based learning assessments for Abstract Background: Having identified substance abuse as an issue of concern in their community, the Alexis Nakota Sioux Nation invited University of Alberta researchers to partner on the cultural adaptation, delivery, and evaluation of a school-based drug and alcohol abuse prevention program. Researchers conducted a literature review of available drug and alcohol prevention programs for children and youth, identifying the Life Skills Training (LST) program as a viable model for cultural adaptation.
Asymmetric behavior of volatility in gasoline prices across different regions of the United States

Volatility in gas prices is affecting all economies globally but the effects are much more pronounced here in the United States. This is true because, with only 5 percent of the world population, the US accounts for 20 percent of the global energy consumption. In fact, the US consumes more gasoline than South America, Europe, Africa and Asia combined according to EIA (Energy Information Administration.) This paper attempts to focus on fluctuations in gas prices across different regions of the US and the effects of exogenous shocks on their volatility by using time series data. The paper uses a Generalized Autoregressive Conditional Heteroscedasticity (GARCH) model and its variant to measure the persistence of shocks to volatility and the asymmetric effects of these shocks. The results show evidence of high persistence of shocks to volatility and signs of an asymmetric behavior in volatility across regions which imply that gas prices may react differently to good news relative to bad news. The study sheds some light on understanding of the behavior of gas prices in the US better, with major implications for investors in the commodity markets.
Power-Sharing Partnerships: Teachers’ Experiences of Participatory Methodology

Background: This article reports on the experiences of teachers as coresearchers in a long-term partnership with university researchers, who participated in an asset-based intervention project known as Supportive Teachers, Assets and Resilience (STAR). In an attempt to inform participatory research methodology, the study investigated how coresearchers (teachers) experienced power relations. We utilized Gaventa’s power cube as a theoretical framework and participatory research as our methodologic paradigm. Method: Ten teachers of a primary school in the Eastern Cape and five teachers of a secondary school in a remote area in the Mpumalanga Province in South Africa participated (n = 15). We employed multiple data generation techniques, namely Participatory Reflection and Action (PRA) activities, observation, focus group discussions, and semistructured interviews, using thematic analysis and categorical aggregation for data analysis. Results: We identified three themes, related to the (1) nature of power in participatory partnerships, (2) coresearchers’ meaning making of power and partnerships, and their (3) role in taking agency. Conclusion: Based on these findings, we developed a framework of power sharing partnerships to extend Gaventa’s power cube theory. This framework, and its five interrelated elements (leadership as power, identifying vision and mission, synergy, interdependent role of partners, and determination), provide insight into the way coresearchers shared their experiences of participatory research methodology. We theorise power-sharing partnerships as a complimentary platform hosting partners’ shared strengths, skills, and experience, creating synergy in collaborative projects.
Ars memorativa

An especially dolorous exercise is to compare our sublime theories of community with the fraught actuality of people trying to live together. It would be a cruel understatement to say that we have not lived up to our own social dreams. And yet it is no less an understatement to say that art often manages to retrieve a sad beauty from the depths of squalor itself. One of the things that is so amazing about Karen Tei Yamashita’s most recent novel, I Hotel, is that she not only retrieves the sad beauty of a particularly fraught period of a particularly squalid community—Asian Americans in San Francisco during the 1960s–70s— but that she does it in a way that is also exhilarating, celebratory. Those familiar with the history of the real I(nternational) Hotel—the one on Kearny and Jackson—know that its loss represented a real cultural defeat; Yamashita’s novel faces that defeat but chooses resilience, however heartbroken, over victimization. As one of the narrators bitterly muses, “maybe in the end you can’t remember nothing, and nobody else remembers nothing. But goddamn, we never give up. All we ever do is survive. ”
Characterization of Composite Films Made from Tin (IV) Oxide and Aluminium Oxide with Impedance Spectroscopy

Much research has been done focusing on the different kinds of mixed phase porous films of nanostructured semiconductors as they play a vital role in catalysis, optoelectronics, energy conversion and storage. Small signal frequency resolved techniques such as impedance spectroscopy (IS) has been used as a tool to resolve the mechanisms of carrier transport, trapping and their interactions in these films. IS measurements yield useful information about physicochemical properties of a system that can be represented by a network of resistances and capacitances in an equivalent circuit. In this study, impedance of composite porous films made from SnO 2 and Al 2 O 3 which have energy band gaps of 3.8 eV and 8.3 eV respectively has been taken into consideration and their behaviour is analyzed using IS to describe the mechanism of charge carrier transportation. It was found out that the composite films have the highest resistance when the Al 2 O 3 composition is 70%.
The Performance of the PSO Algorithm for Solving Unit Commitment Problem

: This paper proposes a Particle Swarm Optimization (PSO) Algorithm to solve unit commitment problem. In this paper, the efficiency of the proposed method has been demonstrated by solving the unit commitment problem using a 24 hour scheduling horizon, for a 26 unit system. For simplicity, the shutdown cost of the generators has been taken equal to zero for every unit proposed method runs minimum number of generators possible to get the load demand satisfied so this is good for industrial applications.
ENVIRONMENTAL MANAGEMENT ACCOUNTING: A CONCEPTUAL MODEL FOR THE REPORTING OF ENVIRONMENTAL COSTS

The overall aim of this study was to identify factors that affect the use of EMA by the hotel sector in South Africa. The research was an exploratory study and qualitative in nature using a single case study with embedded units approach. ABC Hotel Management Group along its 3 hotels located in the province of KwaZulu-Natal, South Africa, met the selection criteria and thus formed part of this study. There were 10 participants in this case study. Additional documents were analysed which included financial statements, policy documents, the Group website, the hotels’ websites, Group Energy Profile Analysis (GEPA) programme, and Building Monitoring Systems (BMS). The results of this research established a number of factors that affect the use of EMA by the hotel sector in South Africa. The adoption of a prototype EMA model by the hotel sector is then suggested by the study.
