MODELING THE MULTIWAVELENGTH EMISSION FROM G73.9+0.9: GAMMA RAYS FROM AN SNR–MC INTERACTION

G73.9+0.9 has been classified as a probable shell-type supernova remnant, though it has also been suggested that it could have a pulsar wind nebula (PWN). Here, a broadband model of the non-thermal emission of G73.9+0.9 from radio to gamma rays is presented. The model includes a new gamma-ray observation obtained by the analysis of seven years of data from the Fermi/LAT telescope. Above 200 MeV, the source is detected with a significance of 13σ and the spectrum of the radiation is best described by a power law with an index of ∼2.5. The leptonic mechanisms are hard to reconcile with the measured radio and gamma-ray spectral energy distribution. A PWN origin for the high-energy emission is also not very likely, due to the lack of detection of pulsars and of X-ray emission in the region, as well as from the shape of the gamma-ray spectrum. Given the possibility that the object is interacting with molecular clouds, a hadronic origin of the high-energy emission is more likely, and the spectral properties of the cosmic rays responsible for this radiation are derived.
OICS: A Knowledge-based Cloud Manufacturing System for Machine Tool Industry

In this paper, an Ontology inference cloud service (OICS) with auto-scaling capability is designed and implemented for the CNC machine tool industry. The OICS is a knowledge-based cloud manufacturing system, and is used to recommend machine tools and cutting tools based on the Ontology inference techniques. Three core functional modules: the Ontology inference module, the VMT (Virtual Machine Tool) module, and the request filtering module, are developed to allow multiple users to perform inference service, and verify the recommended machine tools or cutting tools via VMT simulations. The OICS is implemented and hosted in a cloud virtual machine, called a worker. Furthermore, the worker controller (WCR), is designed to automatically adjust the number of virtual machines to provide users splendid service quality. Finally, we deploy the developed OICS to a public cloud platform, namely Windows Azure, to conduct integrated tests. Testing results of a case study physically applying the OICS to a machine tool factory show that the OICS can successfully recommend suitable machine tools and cutting tools for machining tasks, and support multiple users in a reasonable performance. The results of this paper can be a useful reference for industrial practitioners to construct cloud-based manufacturing systems.

Quelques resultats d’une micro-analyse revelant le lien creativite-empathie et apprentissages de langues etaieront ces propos.
Resistive Bridge Fault Simulation and Analysis for Resistive RAM

Resistive Random-Access Memory (ReRAM) is an interesting emerging memory technology to replace conventional memory devices. ReRAM offers many attractive advantages like densest data storage, non-volatility, fast data access and scalable. Although potentially becoming the main emerging memory, ReRAM still prone to have a defect and fault. Nevertheless, because ReRAM uses a non-CMOS device as its memory cells, any defect might behave differently than the ones happen in the existing semiconductor memories. It means that the available memory tests might not detect defective ReRAM cells, leading to a low quality of manufactured ReRAM products. This paper presents the study of how the ReRAM cells behave when they are impacted by bridge defects. Such a defective behavior is required to develop the efficient memory test. A SPICE simulation was carried out using the Silvaco EDA tools. The simulation shows that bridge defects causes the impacted ReRAM cells to change the stored bit at defect values much lower than the value occur in existing semiconductor memories. This analysis confirms that a new memory test is desired.
Public Sector Added Value: Can Bureaucracy Deliver?

This paper takes stock of our understanding of the ‘architecture’ of public sector resource allocation mechanisms. It is a speculative venture and provides a framework for thinking about issues rather than a completed theoretical model. The concept of architecture is borrowed from the design sciences and is used to explore the conditions of performativity within networks of relational contracts. The age-old question of markets versus hierarchy is too simplistic. Instead, the search is for optimal complex network relationships that are based upon co-operation and participation rather than competition and control. Within these networks the public sector, it is argued, has a new role of acting as a broker in the creation of value. Judging the public sector’s relative effectiveness in the creation of value also requires closer attention to be given to the context within which public sector managers take decisions. In particular it is necessary to acknowledge that they confront the ‘wicked’ problems of society that the electorate demand to be solved. This gives renewed interest in the notion of market failure.
Hybrid organic–inorganic nanocomposites fabricated with a novel biocompatible precursor using sol-gel processing

The synthesis of hybrid organic–inorganic nanocomposite materials containing biopolymers by the sol-gel processing is often faced with severe difficulties owing to their poor compatibility with the common precursors. The problem was solved when tetrakis(2-hydroxyethyl) orthosilicate (THEOS) was recently suggested for the preparation of sol-gel derived nanocomposites. This article summarizes recent data on novel types of hybrid polysaccharide-silica nanocomposite materials fabricated with the help of THEOS. Their formation, properties and structure as well as features and possible mechanism for the sol-gel processes are considered. It is demonstrated that the novel approach is particularly suitable in situations where others are unsatisfactory. This includes systems of which supramolecular organization or phase state is sensitive to the pH of solutions, temperature and addition of organic solvents. One example of a successful application is the immobilization of labile enzymes. The biocompatibility of THEOS allows their activity to be retained, thereby enhancing long-term and thermal stabilities.

This study also indicates that increased body weight and sedentary life style related factors, including poor dietary habits, excess saturated and trans fat, high salt intake, and low-level physical activity may be important as well and family history of cardiac diseases are influential risk factors for HD.Conclusion: So, we have concluded that increasing body weight, physical inactivity, unhealthy eating habits, poor lifestyle has an effect with HD.
YIELD LOSS ASSESSMENT OF SCLEROTINIA STEM ROT OF CANOLA IN IRAN

Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum, is one of the most important diseases of canola (Brassica napus) in Golestan province, the leading canola producer in Iran. In order to assess the yield loss of canola caused by SSR, 80 fields were surveyed in four different regions of the province (Gorgan, Ali Abad, Kalaleh and Gonbad) during 2006-2007, and SSR intensity was recorded weekly in the fields. Study of yield loss-SSR severity relationships by linear, nonlinear and multiple regression analyses with final intensity (Sf), time to initial symptoms (tis), Gompertz rate of disease progress (rG), and standardized area under disease progress curve (SAUDPC) as independent variables indicate that single point and integral models were significant (P < 0.05) only in three cases. Results of multiple point models which were performed using weekly recorded SSR intensities (S1, S2, …), were significant in two cases and a general model for 2007 survey was developed using S3 to S6. Eventually, response surface models were developed for each region by integrating tis with SSR intensity variables (Sf or SAUDPC).
A CTF-Based Approach in Information Security Education: An Extracurricular Activity in Teaching Students at Altai State University, Russia

Capture the Flag (CTF) competitions are the most popular events in cybersecurity conferences where participants can demonstrate their skills. Also, the CTF is widely acknowledged as a valuable pedagogical tool for providing the students with real life problems in computer security area when dealing with CTF tasks. However, there is the possibility to go beyond treating CTF tasks only. The paper presents an approach to establish a CTF-based educational framework that allows students to gain more practical skills, knowledge and expertise in information security and related areas. The framework is implemented in Altai State University (Barnaul, Russia) in 2014 as an extracurricular club activity, and the club runs successfully up till now. Pedagogical benefits, learning methodology and educational aspects are discussed, and positive feedback shows the success of the proposed approach.
Analog Circuits Design Using Ant Colony Optimization

In this paper, we present, Ant Colony Optimization (ACO) algorithm, as a tool to design analog circuits, for given output specifications. ACO is a swarm intelligence algorithm, which was first proposed in early nineties, to solve the problems of combinatorial optimization. In this paper, a modified version of this algorithm, (for continuous domain) has been implemented to optimize transistor sizes. In this work, widths of transistors are found for three analog circuits, to achieve the given specifications. Also, ACO has been tested on an Analog to Digital (ADC) Converter. Performance of the ADC is improved by optimizing the widths of the transistors, to minimize the error in the output of the ADC. In the past, one of the most popular evolutionary algorithms, Genetic Algorithm (GA) has been found to be effective in optimizing transistor sizes. Therefore, to examine the solutions achieved by ACO, all the circuits are optimized by GA also. Results show that ACO is better than GA in finding transistor sizes. Also, ACO takes less time in optimization process. In this work, Perl code of algorithms has been coupled with HSPICE to do circuit simulations. All circuits are simulated using BSIM3v3 MOSFET models in 0. 13µm, 0. 18µm or 0. 35µm CMOS processes.
Scattering polarization of molecular emission lines in the quiet solar chromosphere

We present scattering polarization measurements performed with THEMIS in July 2000 near the south polar limb. The low level of scattered light at THEMIS, which is the only large solar telescope to include a superpolished primary mirror, allows, in good seeing conditions, to observe the emission spectrum of the low chromosphere above the limb. These are, as far as we know, the first high spectral resolution observations of the intensity and the first measurements of the polarization of C 2 and MgH molecular lines in emission above the limb. Molecules are present in a thin layer in the region of the temperature minimum between the photosphere and the chromosphere. We present a very simple model for the formation of the polarized lines and we relate the observed polarization rates to the so-called intrinsic line polarizability coefficients W 2 . Those quantities may be derived from quantum mechanical computations involving the solution of the Schrodinger equation for the molecular potential. Solar observations provide a direct way of checking these heavy computations and contribute to the improvement of our knowledge in molecular physics. Nine C 2 molecular transitions and two MgH transitions are present in our spectral window; we find that for the C 2 transitions, the polarizability is between 0.13 and 0.26 and that it takes higher values, namely 0.41 and 0.46, for the two MgH transitions.
Existence of Nontrivial Solutions for Periodic Schrödinger Equations with New Nonlinearities

We study the Schrodinger equation: , where is -periodic and is -periodic in the -variables; is in a gap of the spectrum of the operator . We prove that, under some new assumptions for , this equation has a nontrivial solution. Our assumptions for the nonlinearity are very weak and greatly different from the known assumptions in the literature.
Seismotectonics of the Pamir

Based on a 2 year seismic record from a local network, we characterize the deformation of the seismogenic crust of the Pamir in the northwestern part of the India‐Asia collision zone. We located more than 6000 upper crustal earthquakes in a regional 3‐D velocity model. For 132 of these events, we determined source mechanisms, mostly through full waveform moment tensor inversion of locally and regionally recorded seismograms. We also produced a new and comprehensive neotectonic map of the Pamir, which we relate to the seismic deformation. Along Pamir's northern margin, where GPS measurements show significant shortening, we find thrust and dextral strike‐slip faulting along west to northwest trending planes, indicating slip partitioning between northward thrusting and westward extrusion. An active, north‐northeast trending, sinistral transtensional fault system dissects the Pamir's interior, connecting the lakes Karakul and Sarez, and extends by distributed faulting into the Hindu Kush of Afghanistan. East of this lineament, the Pamir moves northward en bloc, showing little seismicity and internal deformation. The western Pamir exhibits a higher amount of seismic deformation; sinistral strike‐slip faulting on northeast trending or conjugate planes and normal faulting indicate east‐west extension and north‐south shortening. We explain this deformation pattern by the gravitational collapse of the western Pamir Plateau margin and the lateral extrusion of Pamir rocks into the Tajik‐Afghan depression, where it causes thin‐skinned shortening of basin sediments above an evaporitic décollement. Superposition of Pamir's bulk northward movement and collapse and westward extrusion of its western flank causes the gradual change of surface velocity orientations from north‐northwest to due west observed by GPS geodesy. The distributed shear deformation of the western Pamir and the activation of the Sarez‐Karakul fault system may ultimately be caused by the northeastward propagation of India's western transform margin into Asia, thereby linking deformation in the Pamir all the way to the Chaman fault in the south in Afghanistan.
Assessing Macro-Financial Linkages: A Model Comparison Exercise

The recent global financial crisis has increased interest in macroeconomic models that incorporate financial linkages. Here, we compare the simulation properties of five mediumsized general equilibrium models used in Eurosystem central banks which incorporate such linkages. The financial frictions typically considered are the financial accelerator mechanism (convex \spread costs related to firms' leverage ratios) and collateral constraints (based on asset values). The harmonized shocks we consider illustrate the workings and mechanisms underlying the financial-macro linkages embodied in the models. We also look at historical shock decompositions of real GDP growth across the models since 2005 in order to shed light on the common driving factors underlying the recent financial crisis. In these exercises, the models share qualitatively similar and interpretable features. This gives us confidence that we have some broad understanding of the mechanisms involved. In addition, we also survey the current and developing trends in the literature on financial frictions.
Palaeo-lake and Swamp Stratigraphic Records of Holocene Vegetation and Sea-level Changes, Mangaia, Cook Islands

Stratigraphy of swamps inside the inner makatea rim of Mangaia was investigated to show Holocene changes in vegetation and sea level. In the mid-Holocene five lakes existed where there are now clay-filled swamps, and lake notches on the makatea wall indicate that sea level was sustained at 1.1 m higher than present. Fine annual laminations in gyttja deposits indicate the greatest lake depth in that period, dated between 6500 and 4500 yr B.P. Pollen evidence of wetland communities also points to a higher sea level at that time. Pollen analyses and charcoal concentrations of cores from two different drainage basins show that the greatest change in terrestrial vegetation of the Holocene on Mangaia was clearance of forest by people, resulting in soil erosion from the inner volcanic cone and clay infilling of the lakes. Humans were present on Mangaia as early as 2500 yr B.P. Although some clearance of forest occurred during that early period of human occupation, systematic island-wide anthropogenic disturbance began ca. 1650 yr B.P., as shown in both cores from a decline in forest pollen and a major and sustained increase in Dicranopteris, a fern that colonizes disturbed land.
Evaluating the welfare effects of biodiversity on private lands: A choice modelling application

Biodiversity loss is a global problem, especially in reference to private lands. In response, we investigated whether private land biodiversity may be attained by developing incentives which include funding landholders through the provision of native trees to enhance biodiversity on their own properties. Using choice modelling, we tested this hypothesis. A typical respondent was found to be better off, in terms of welfare, if there was a biodiversity enhancing scheme in their locality. We also found that respondents in the upper northern regions of New Zealand were relatively more receptive in supporting biodiversity enhancement programmes on their properties, compared to those residing in the southern regions of the country.

Usability of Web-based Knowledge Portals to support Research Organizations

Usability refers to the effectiveness, efficiency and user satisfaction of a designed product or system. One of the most of productive ways of measuring usability goals is through questionnaires and surveys. In this paper, we discuss usability related issues from a users’ perspective in the design analysis of a web-based knowledge portal that was developed to support the knowledge management activities of an educational research organization. The original portal system initially experienced high levels of user participation. However in recent times, this trend had been reversed with flagging log-in access rates. Consequently, a criterion-based usability survey instrument was designed and implemented online to gather users’ responses and comments. The survey outcomes indicated that a large number of respondents used the portal sporadically with a significant number being completely unaware of many of its services. Thus based upon this feedback, the existing portal was revamped to ensure a more user-centric design model that focused on the cornerstone aspects of user control, ease of navigation, personalization services and clarity in visual presentation of information.
A Quasi-Experiment of Exercise Modality Effects on Cognition and Fitness in Healthy Women

Exercise has been shown to improve cognitive function in many clinical populations. However, there is not a standard exercise prescription for improving cognition among adults. The purpose of this study was to assess the feasibility of standardizing an exercise prescription for cognitive improvement, without reducing fitness benefits of exercise. Healthy women were assigned to a moderately intense floor/step aerobics (FSA; n = 8), treadmill walking (TMW; n = 9), or stretching (STR; n = 10) intervention for 7 weeks. Cognition and fitness were assessed pre-, mid-, and post-intervention. FSA participants experienced a significantly reduced time to complete the Trail Making Test-A compared to those in TMW or STR (P = 0.016). In conclusion, participation in FSA may result in greater cognitive gains than does participation in TMW, while still providing fitness benefits. For women desiring to improve their cognition and fitness, prescription of moderately intense FSA for 150 minutes each week should be considered.
Dedicated to Mom and Dad

This thesis reports on two systems where very simple, non-communicating mobile agents in a cellular (lattice) environment use purely local rules to construct two different kinds of structures. In the first system, agents construct connected structures from initially randomly distributed building blocks. The effect of block density on the final structure is studied, demonstrating a percolation-like phase transition: Low block densities lead to the formation of small, disconnected structures but a single connected structure emerges abruptly beyond a critical density. The empirical study of the structure at the transition point shows scaling behavior, providing strong evidence for criticality. We also demonstrate that a simple change of rules can dramatically change the phase transition effect. The results have implications for the self-organized construction of complex structures by swarms. In the second system, agents construct walled enclosures around a number of nonmobile nodes which possibly represent resource locations or sites / items of interest. The walled enclosure is constructed in two stages: 1) A pheromone template is first built and maintained by the agents, and 2) A single connected wall is built that fully surrounds all the nodes in the environment. We show that the shape of the enclosure produced can be predicted approximately in cases where the nodes form a convex shape. We also show that the shape can be “guided” systematically to a limited degree.
