Global Stability of a Computer Virus Propagation Model with Two Kinds of Generic Nonlinear Probabilities

Vaccination is one of the most effective measures for suppressing the spread of computer virus, and the bilinear incidence rate assumption for the majority of previous models, which is a good first approximation of the general incidence rate, is in disagreement with the reality. In this paper, a new dynamical model with two kinds of generic nonlinear probabilities (incidence rate and vaccination probability) is established. An exhaustive mathematical analysis of this model shows that (a) there are two equilibria, virus-free equilibrium and viral equilibrium, and (b) the virus-free (or viral) equilibrium is globally asymptotically stable when the basic reproduction number is less (or greater) than unity. The analysis of the basic reproduction number is also included. Additionally, some numerical examples are given to illustrate the main results, from which it can be seen that the generic nonlinear vaccination is helpful to strengthen computer security.
Effectiveness evaluation of data link based on the improved grey interval correlation degree

To solve the problem of the fuzzy multiple attribute decision making, the improved grey interval correlation degree was proposed. In the improved method, the attribute values took the form of the interval numbers; it proposed an algorithm for comparing the size of interval numbers and used the combination weighting method to make the weights more reasonable. To evaluate the effectiveness of the system, the concrete steps of the improved method were given. It used analytic hierarchy process (AHP) and Delphi method to establish the scientific and reasonable index system of data link. An example was analyzed and the results show that the improved method is reasonable and feasible. The improved method can be used to rank the limited projects and select the optimal one through dealing with the interval numbers.
Effects of Different Cooking Methods on Improving Total Antioxidant Activity in Selected Vegetables

The present study compares Water-soluble Phenolic Content (WPC) and antioxidant activities in eggplant, kidney bean, bitter gourd and spinachprior to and after subjecting to boiling, microwaving and pressure cooking. The total antioxidant activity was increased in cooked spinach, eggplant and bitter gourd, estimated based on the ferric reducing antioxidant power, the Troloxequivalent antioxidant capacity and 2, 2-diphenyl-1-picryl-hydrazyl radical scavenging activity. Pressure cooking did not cause any significant decline in the antioxidant property. Boiling generally improved the overall antioxidant activity in all the vegetables. Correlation analysis suggests that WPC contributed to significant antioxidant activities in these vegetables. Thus, prudence in selecting an appropriate cooking method for different vegetables may improve or preserve their nutritional value.
Learning from Social Data: Non-exchangeable Priors in the Social Sciences - eScholarship

Bayesian analyses are often critiqued on the basis of dubious exchangeability claims regarding the data. Not only must observed data be exchangeable, but prior ``data'' must be as well, and the observed data must also be exchangeable with the prior data--an assumption not typically justified by the practitioner. Yet social scientists often utilize social data--observed human behaviors that rely on human judgment--to make inferences. Social priors shared by the researcher are, therefore, non-exchangeable with social data. One common defensive argument offered by Bayesian practitioners is that as long as there is some component of new information in the observed data, repeated observation-updating cycles will still eventually produce a highly informative posterior distribution. In frequentist statistics we have power analyses--a way of estimating how much data we need to get desirable properties from our estimator. Here I develop a model that parameterizes the degree of non-exchangeability between the observed data and the prior data and offers a standard way to calculate how many observations are needed to achieve a parameterized definition of an informative Bayes' estimate in a single iteration of updating, or the number of updating iterations needed given a fixed observation size n at each iteration. I illustrate the phenomenon with a combination of real and model-synthesized data showing how New York police officers who make stops learn from social data---convictions generated by jury trials in the U.S. justice system.
Dietary sesame seed hulls utilization on lamb performance,lipid oxidation and fatty acids composition of the meat

The objective of this study was to evaluate the dietary use of sesame seed hulls on lamb performance parameters and some meat quality characteristics. A total of 36 lambs of Pelagonia (Florina) breed 68 ± 5 days old and with average initial body weight 18.5 ± 2.6 kg, were randomly allocated to 3 groups. The lambs of the Control group were fed a normal diet based on alfalfa hay, wheat straw and concentrate feed (mainly maize, barley and soybean meal), whereas those from Groups S100 and S200 were fed alfalfa hay, wheat straw and concentrate feeds containing sesame seed hulls at 100 g/kg feed and 200 g/kg feed, respectively. After 9 weeks, experimental period, the animals of Group S200 had significantly (P<0.05) better final body weight, fasting live weight, weight with empty rumen, hot carcass weight, and cold carcass weight compared to the Control group. Moreover, the dressing percentage was significantly higher (P<0.05) for group S200, compared to group S100, but not compared to the controls. Meat lipid oxidation measured as thiobarbituric acid reactive substances content did not differ among all three groups (P>0.05) after 2 or 4 days of refrigeration. Moreover, the fatty acid profile of the meat did not differ (P>0.05) for saturated, monounsaturated and polyunsaturated fatty acids among all groups. In conclusion, sesame seed hulls can be used in lamb nutrition with some possible benefits regarding the performance parameters.

Veterans' experiences of patient-centered care: Learning from guided tours

In this paper the authors seek to examine Veterans’ experiences with patient Veterans Affairs (VA) facilities. The authors conduct their participant leads the evaluator through an environment and shares thoughts, feelings, conducted in April 2013 with 30 Veterans receiving care at these VA facilities. aspects of the environment of care, and described some as ‘welcoming,’ while describing others as ‘chaotic. ’ Participants provided multiple examples of PCC, frequently defining PCC in terms of accessibility of appointments, familiarity with providers, and shared decision Veterans influenced their preferences for care, including efficiency, need for compassion, and consideration of mental and social health needs. Some suggested VA expand upon this idea of shared identity by creating a ‘Veteran community,’ and including increased opportunities for socialization with other Veterans, and access to the arts. The authors conclude that the impact of shared identity on care preferences has received limited attention in the literature; further, the impact of identity may be unique to Veterans, who represent not only a group of patients being seen at the same facilities, but a social group with shared his implementation of PCC innovations, to improve health and well
Screening of Halophilic Lipase-Producing Bacteria and Characterization of Enzyme for Fish Sauce Quality Improvement

Twenty pure bacterial cultures isolated from Thai fish sauce were selected for lipase producing on Sehgal and Gibbons Complex (SGC)-Tween 80 agar containing 0-4 M NaCl. The results showed that isolate PB233 could produce the highest lipase activity. This isolate was identified based on morphological, physiological characteristics and compared 16S rRNA sequence to other bacteria. It was concluded that isolate PB233 belonged to Staphylococcus warneri. This strain could grow in 0-4 M NaCl but the best growth was observed at 0 M NaCl. Therefore, Staphylococcus warneri was classified as halotolerant bacteria. A halotolerant Staphylococcus warneri PB233 was cultured in mini jar fermenter using SGC medium containing 1% olive oil and 3 M NaCl. A typical pattern of lipase production showed that enzyme secretion was coupled to active cell multiplication and maximum activity was obtained at a stationary phase. The maximum production of lipase (90.12 U/ml) was observed at 48 hr. The lipase had optimum at pH 7.0 and at temperature of 40°C. It was stable between pH 7.0 and 9.0 and at temperatures between 30 and 40°C. This enzyme had marked halophilic enzyme properties and showed maximal activities in the presence of 2.5 M (15%) NaCl.

In addition, insights about Native Hawaiian leadership in general and suggestions for future research are offered.
IPC 2014-33695 DIRECT COMPARISON OF SINGLE-SPECIMEN CLAMPED SE ( T ) TEST METHODS ON X 100 LINE PIPE STEEL

The clamped single edge-notched tension (SE(T)) specimen has been widely used in a single-specimen testing scheme to generate fracture resistance curves for high strength line-pipe steels. The SE(T) specimen with appropriate notch geometry is a low-constraint specimen designed to reduce conservatism in the measurement of fracture toughness. The crack driving force is taken as either the J-integral or crack tip opening displacement (CTOD); it is generally accepted that the two parameters are interchangeable and equivalent using a simple closed form solution. However, the assumption that they are interchangeable, and to what extent, hasn’t been previously investigated experimentally on the same SE(T) specimen. This paper presents multiple test methods that were simultaneously employed on the same SE(T) specimens. The instrumentation includes: clip-gauges to measure surface crack mouth opening displacements (CMOD) and CTOD by the double-clip-gauge method; strain-gage arrays for direct J-integral measurements; and direct-current potential-drop (DCPD) instrumentation for supplementary crack size measurement. A direct comparison of ductile crack-growth resistance curves generated using Jintegral and CTOD is presented here where each represents a different experimental and analytical approach. The two methods are in reasonable agreement over a narrow range of crack growth, differing slightly at initiation and diverging with increasing crack growth. Analysis of the supplementary instrumentation (i.e., strain gages, extensometers and DCPD) will be provided in a future publication.
THE SOLID SOLUTIONS OF REBULITE AND JANKOVIĆITE IN THE PHASE SYSTEM Tl 2 SAs 2 S 3-Sb 2 S 3

Syntheses along the Tl5(As,Sb)13S22 compositional line in the Tl2S-As2S3-Sb2S3 phase system showed that the compositional range of rebulite extends from Tl5As9.5Sb3. 5S22 to Tl5As7.75Sb5. 25S22. The Sb-rich end-member is in equilibrium with jankovićite of the ideal composition Tl5Sb7.5As5. 5S22, which is considered to be the As-rich end-member of the jankovićite solid solution. The crystal structure analysis of specimens from the As and Sb end-members of rebulite show that the Sb/As substitution is present in Sb3, Sb4, Sb5, As1 and As2 structural sites. Of them, Sb3 is always Sb dominated whereas other four vary from Asto Sb-dominated over the range of the solid solution. The change of the structural topology from jankovićite to rebulite, closely related but not identical structures, is explained through the necessity to accommodate the smaller volumes of the As coordination polyhedra, and is accomplished through unitcell twinning over the periodic (001)reb twin boundaries. The As end-member of the rebulite solid solution is in equilibrium with a phase of composition close to Tl2.4Sb0. 68As7.18S13, interpreted as imhofite.
Improvement Anomaly Intrusion Detection using Fuzzy-ART Based on K-means based on SNC Labeling

Intrusion detection has received a lot of attention from many researchers, and various techniques have been used to identify intrusions or attacks against computers and networks. Data mining is a well-known artificial intelligence technique to build network intrusion detection systems. However, numerous data mining techniques have been successfully applied in this area to find intrusions hidden in large amounts of audit data through classification, clustering or association rule. Clustering is one of the promising techniques used in Anomaly Intrusion Detection (AID), especially when dealing with unknown patterns. This paper presents our work to improve the performance of anomaly intrusion detection using Fuzzy-ART based on the K-means algorithm. The K-means is a modified version of the standard K-means by initializing the value K from the value obtained after data mining using Fuzzy-ART and SNC labeling technique. The result has shown that this algorithm has increased the detection rate and reduced the false alarm rate compared with Fuzzy-ART.
Presidential Election 2012: How French politicians tweet?

Tweets exchanged over the Internet is an important source of information even if their characteristics make them difficult to analyze (e.g., a maximum of 140 characters). In this paper, we address the problem of analyzing the opinions expressed through tweets for di erent communities. More precisely we are interested in following, over time, what is the opinion that a community can have for a speci c term or expression (e.g., is the opinion of tweets using the term "crisis" remain the same over time for a political party? ). Furthermore we are also interested in shared terms or expressions between di erent communities. In this case our goal is to evaluate if the opinion expressed changes a lot between communities. Conducted experiments on tweets for the upcoming French Presidential election show very interesting results.
Feeding habits and trophic level of sea bass (Dicentrarchus labrax) in the Messolonghi-Etoliko lagoons complex (Western Greece)

Information on the quality and quantity of consumed food by fish is important for the classic ecological theory, mainly in identifying omnivory, feeding competition, assessing predator-prey functional responses and structure as well as the stability of food webs (Gerking, 1994). Diet composition data are also used for the estimation of trophic levels. The trophic level expresses the relative position of an animal in the food webs that nourish them ranging, for marine animals, between 2 (herbivores / detritivores) and 5.5 (specialised predators such as marine mammals) (Pauly et al., 2000). The estimation of trophic level allows the development of new approaches to the analysis of marine food webs and thereby it is essential for the management of fisheries resources as well as for quantifying the effects of fishing on the ecosystem (Pauly et al., 2000; Stergiou & Karpouzi, 2002). Coastal lagoons and estuaries play an important role as nurseries, offering food and shelter for the larval, juvenile and adult stages of numerous fish species that spawn in the open sea (Costa et al., 2002). The improvement of aquatic lagoon environments is among the aims of the EU Directive 2000/60/EC (Water Framework Directive, WFD), which defines qualitative, quantitative and ecological objectives aiming at the protection of these highly valuable ecosystems (Elliott & McLusky, 2002).

Assessing Crop Yield Sustainability under the Climatic and Bioclimatic Change in the Area of Palestine

We analyzed plant production such as olive, grape and fig in several Palestinian Occupied Territories, and studied the correlation analyses between productions and climatic, bioclimatic features in the territory. This work examines the following climate factors: average temperature, precipitation, soil water reserve and water deficit; and bioclimatic parameters such as compensated thermicity index, ombrothermic index and continentally index. The data used were from nine meteorological stations of the Palestinian Meteorological Department. The study was based on the correlation analyses between olive, grape and fig production in nine plots: Hebron, Ramallah, Nablus, Jenin, Jericho, Bethlehem, Jerusalem and Tulkarem over fourteen years. The analysis of variance revealed a significant influence of the variables temperature and compensated thermicity index on the production of olive and fig, and a low influence on grape production. When we applied canonical correspondence analysis (CCA), the Nablus, Jenin, Jericho and Gaza plots were most affected by the climate factors as temperature, and bioclimate factors as compensated thermicity index, whereas, the Hebron, Bethlehem, Jerusalem, Tulkarem and Ramallah plots showed the influence of ombrothermic index, continentally index, precipitation, water deficit and soil water reserve.
Hotel Industry Regulations and Cross-Border Franchising: The Case of Saudi Arabia

Saudi Arabia has formulated and enforced a new tourism law to develop its tourism sector with special emphasis to open more international activities in the hotel industry. The main objective of this study was to determine the influence of new regulations of hotel industries in Saudi Arabia on the decision making process of the hotel companies in relation to international franchising. Qualitative research design was used to investigate the connection between new regulations of hotel industry in Saudi Arabia and its cross-border franchising activities. Data was retrieved from two primary sources: governmental agencies and, the hotel and leisure companies involved in franchising. The main sectors covered were the investment in tourism lands, establishment of tourism based associations, and replacement of foreigners, price and classification. Data was generated through twelve in-depth interviews with the representatives of the sample companies, from April to September 2016. The primary data generated during interviews was complemented by data from industrial publications and the annual reports to know about the current status of Saudi hotel industry and the activities of the sample companies. Findings confirmed that the regulatory reforms of a hotel industry, by following new hotel-based regulations, added new vigor to hotel based industry and enhanced its international profile. The new tourism law authorized the Saudi Commission for Tourism and Heritage (SCTH) to identify and propose new lands for tourism investment, which may increase its importance among the global hotels’ franchisors.
The cross-spectrum experimental method

The noise of a device under test (DUT) is measured simultaneously with two instruments, each of which contributes its own background. The average cross power spectral density converges to the DUT power spectral density. This method enables the extraction of the DUT noise spectrum, even if it is significantly lower than the background. After a snapshot on practical experiments, we go through the statistical theory and the choice of the estimator. A few experimental techniques are described, with reference to phase noise and amplitude noise in RF/microwave systems and in photonic systems. The set of applications of this method is wide. The final section gives a short panorama on radioastronomy, radiometry, quantum optics, thermometry (fundamental and applied), semiconductor technology, metallurgy, etc. This report is intended as a tutorial, as opposed to a report on advanced research, yet addressed to a broad readership: technicians, practitioners, Ph.D. students, academics, and full-time scientists.
COPLANAR WAVEGUIDE BAND REJECT FILTER USING ELECTROMAGNETIC BAND GAP STRUCTURE

This paper presents design and analysis of six different configurations of Coplanar Waveguide Band Reject Filters (CPW-BRF) using Rectangular Dumbbell Electromagnetic Band Gap (RDEBG) cell structures. The performance in terms of rejection bandwidth, attenuation, cutoff characteristics of the proposed design are found superior to the earlier reported CPW-BRF. Using cascading of six RDEBG cells, rejection bandwidth has been improved up to 2.8 GHz with attenuation of −38.8 dB and filter selectivity of 26.9 dB/GHz. In addition, the radiation losses have also been analyzed by extracting equivalent R, L and C values from electromagnetic (EM) simulation results. Fabricated CPW-BRF using four RDEBG cells has been analyzed. For the fabricated CPW-BRF simulated and measured results are found in good agreement.
Practical machine learning and its application to problems in agriculture

One of the most exciting and potentially far-reaching developments in contemporary computer science is the invention and application of methods of machine learning. These have evolved from simple adaptive parameter-estimation techniques to ways of (a) inducing classification rules from examples, (b) using prior knowledge to guide the interpretation of new examples, (c) using this interpretation to sharpen and refine the domain knowledge, and (d) storing and indexing example cases in ways that highlight their similarities and differences. Such techniques have been applied in domains ranging from the diagnosis of plant disease to the interpretation of medical test data. This paper reviews selected methods of machine learning with an emphasis on practical applications, and suggests how they might be used to address some important problems in the agriculture industries.
Untargetted Metabolomics in Assessment of Variations among Kenyan Arabica Coffee Genotypes Using Organic Compounds in the Brew

Genotypical variations between two commercial coffee cultivars considered as controls (Ruiru 11 and SL28) and five other genotypes under investigation (Cr8, Cr22, Cr23, Cr27 and Cr30) all grown under similar conditions were evaluated. Organic compounds were extracted using C18 Solid Phase Extraction (SPE) cartridges and analyzed by Gas Chromatography- Mass Spectrometry. Untargeted metabolomics data processing of the mass spectra was carried out on XCMS online (a web based platform). The analysis revealed absence of any significant variation in composition of the organic compounds at p = 0.05. However, from the Principal Component Analysis plots the genotypes Cr27, Cr22 and Cr23 clustered close together with Ruiru 11 while the other genotypes showed no distinct clustering pattern. Overall, there was no significant variation in the organic compounds composition across the coffee genotypes grown under similar agronomic practices in the same region and processed uniformly.
