Continuum excitations of $^{26}$O in a three-body model: $0^+$ and $2^+$ states

The structure and decay dynamics for $0^+$ and $2^+$ continuum excitations of $^{26}$O are investigated in a three-body $^{24}$O+$n$+$n$ model. The validity of a simple approximation for the cross section profile for long-lived $2n$ emission is demonstrated. A sequence of three $0^+$ monopole ("breathing mode" type) excited states is predicted. These states could probably be interpreted as analogues of Efimov states pushed in the continuum due to insufficient binding. The calculated energies of the $2^+$ states are related to the excitation spectrum of $^{25}$O. We discuss the correlation between the predicted $^{26}$O spectrum and experimental observations.
Food imports, international prices, and violence in Africa

This study examines the effect of food price fluctuations on violence in Africa, using international food prices as a source of exogenous shock weighted by a country’s import pattern of major food commodities to create a country-specific food price index. The regression analysis shows that between 1990 and 2011, food price increases are associated with higher levels of violence. Moving from low to high values in the price index corresponds, after controlling for economic, social, and political factors, to an increase in violence intensity of 1.3 incidents. This effect is predominantly driven by imports of low-value-added primary products. Despite the statistically significant results, the predictive power of food prices is relatively low, both in and out of sample. Using 2012 data for out-of-sample forecast shows that food prices are a relatively poor predictor of violence.

Compensation of phase nonlinearity of liquid crystal spatial light modulator for high-resolution wavefront correction

The ability of phase modulation enables liquid crystal spatial light modulator (LCSLM) to control wavefront. However, the disadvantage of its inherent nonlinear phase response will decrease the wavefront control accuracy. In this paper, a compensation for the nonlinear phase response is proposed based on Inverse Interpolation method. Characteristic curve of phase retardation versus gray levels for a 256x256 pixels phase-only LCSLM has been measured and calibrated by Inverse Interpolation. A mapping relationship between input gray levels and driving gray levels has been built and recorded by a linear look-up table ANTI2.LUT. The nonlinear error of the phase drops from 15.9% to 2.42% by using ANTI2.LUT. Further more, the mapping curve of ANTI2.LUT is almost consistent with 290.LUT from the manufacturer, which proved the efficiency of the compensation of phase nonlinearity. Finally, the distorted wavefront caused by a liquid crystal flake is corrected using LCSLM based on ANTI2.LUT. Experimental results show that the peak-valley value of the distorted wavefront decreases from 1.56l to 0.26l (l =0.6328 λm), the root-mean-square value decreases from 0.25l to 0.02l and the Strehl ratio of diffractive spots increases from 0.08 to 0.97. So LCSLM can be applied to realize high-precision and high-resolution wavefront correction with linear phase response.
User-Centered Design of a COPD Remote Monitoring Application Experiences from the EU-project United 4 Health

Recent health reforms in Norway have produced changes at all levels of the health sector, bringing to light a need for technology solutions explicitly designed for enhancing end-user collaboration. Telemedicine technology can support in this context new services that enable communication across local borders, optimizing resources and increasing cost effectiveness. This study focuses on the user-centered design, iterative development and evaluation of the user interface of a mobile application for a new telemedicine service for remote monitoring of chronic obstructive pulmonary disease patients. The tablet device application was developed based on information gathered in a workshop and group interviews where the end-users, e.g., patients and health professionals, described their preferred way of interacting with the telemedicine technology. User evaluations showed positive results on the ease of use and user satisfaction regarding the interaction with the application. Application’s user interface refinements were made iteratively through several end-users’ evaluations, resulting in a fully developed system suitable for remote monitoring of chronic obstructive pulmonary disease patients. Furthermore, the process led to the deployment of a telemedicine system, adopted by the partners of the project United4Health as part of the 7 Framework Programme for Research of the European Union. Keywords-user-centered design; telemedicine; software development; usability evaluation.
A Finite-Volume Formulation for Fully Compressible Premixed Combustion using the Level Set Approach

The level set approach is used for fully compressible simulations of premixed combustion. The motivation of the present work is to numerically simulate thermo-acoustic combustion instabilities. These instabilities are excited by the interaction of heat release and pressure fluctuations, which can numerically only be accurately accounted for in fully compressible simulations. A major challenge is the discretization and the inclusion of the heat release due to combustion at the flame front. To this end, a finite-volume formulation, which uses the ideas of the ghost-fluid method [Fedkiw et al. J. Comp. Phys. 154, 393-427 (1999)], is developed based on a low-dissipation scheme which has been successfully used for large-eddy simulations of non-reacting flows. Mots clefs : Level set approach, G-equation, Premixed combustion, Compressible Navier-Stokes equations
DETECTION OF PORK CONTAMINATION IN FRESH AND COOKED BEEF USING GENETIC MARKER MITOCHONDRIAL-DNA CYTOCHROME B BY DUPLEX-PCR

By mixing with pork, beef adulteration is frequently found in the traditional market that very disturbing Moeslem community in Indonesia. This study was conducted to detect pork contamination in fresh and cooked beef using genetic marker mitochondrial DNA cytochrome b (mt-DNA Cyt b) by duplex-PCR. A total of twelve samples was used in this study consisting six fresh meat samples and six cooked meat samples, respectively. Those beef and pork were bought from animal slaughterhouse and a supermarket in Surakarta. Cooked samples were prepared by boiling the meats in hot water at 100oC for 30 minutes. We designed pork contamination in beef in the level of 0, 1, 5, 10, 25%, respectively. The DNA genome was extracted and polymerase chain reaction (PCR) was performed using species specific primer to isolate mt-DNA Cyt b gene from the samples. The results showed that the DNA genome was successfully extracted from pork, beef, and contaminated meat samples. In addition, visualization of duplex-PCR on 1.5% agarose gel was able to detect pork contamination in both fresh and cooked beef up to very small proportion (1%). The existence of pork in beef was indicated with the presence of specific 398 bp DNA band. It can be concluded, duplex-PCR of mt-DNA Cyt b gene was very sensitive in detection of pork contamination in fresh and cooked beef.
Impact of Parthenium hysterophorus L. (Asteraceae) on soil chemical properties and its distribution in a reserve area: A case study in Awash National Park (ANP), Ethiopia

The study was conducted in Awash National Park (ANP), East Shewa Zone of Oromia National Regional Sate, Ethiopia, and aimed at determining the impact of parthenium weed (Parthenium hysterophorus L.) on soil chemical properties and assessing the current distribution of the weed in the Park. A transect belt of 13.5×0.10 km of parthenium weed infested land was identified. Four quadrats were purposively laid every 250 m interval two for infested and two for non-infested each from both sides of the road where the weed highly and uniformly distributed. A total of 216 soil samples were collected from the top 10 cm. Most of the soil parameters considered in this study were found to be better for the infested quadrats than non-infested quadrats, suggesting that parthenium weed does not impose adverse impact on soil nutrients. The distribution of the weed following the highway indicated that vehicular transportation could be the major way of dispersal in ANP. The control strategy should, thus, focus mainly on these factors without undermining the contribution of livestock and overgrazing. Key words: Fentale Mountain, invasive alien species, sugar cane plantation.
LAYER-BY-LAYER ASSEMBLY OF ACRYLATE COPOLYMERS AND CDTE NANOPARTICLES

Mercaptoacetic acid-stabilized CdTe quantum dots (QDs) are prepared directly in aqueous solution. The multi-layer films of acrylate copolymer and CdTe nanoparticles were obtained by the layer-by-layer electrostatic self-assembly. It is shown that positively charged acrylate copolymer can be directly assembled outside the anionic CdTe QDs through an electrostatic force. The optical properties of the CdTe nanoparticles and the film build-up are monitored by employing the absorption and fluorescence spectroscopy. The deposition process is linearly related to the number of bi-layers as monitored by UV-vis absorption spectroscopy. The fluorescence intensity of ultrathin film rises with the DM content (9.69%, 16.29%, and 36.55%) in the acrylate copolymer and the photoluminescence spectra of multi-layers exhibit a red shift, indicating the enhancement of electrostatic forces between the carboxyl groups of thioglycolic acid capped on CdTe quantum dots and quaternization acrylate in cationic copolymer. The electrostatic interaction on the surface of the CdTe was enhanced with the DM content in the copolymer. Characterization of the multi-layer structures has been carried out by X-ray photoelectron spectroscopy. At the same time, the membrane morphology is investigated by atomic force microscopy. Electrostatic forces between anions in CdTe nanocrystals and cations in the copolymer strengthen the stability of the inorganic/organic compound because it played the role of surface passivation in CdTe QDs.
Experimental demonstration of ultrasensitive sensing with terahertz metamaterial absorbers: A comparison with the metasurfaces

Planar metasurfaces and plasmonic resonators have shown great promise for sensing applications across the electromagnetic domain ranging from the microwaves to the optical frequencies. However, these sensors suffer from lower figure of merit and sensitivity due to the radiative and the non-radiative loss channels in the plasmonic metamaterial systems. We demonstrate a metamaterial absorber based ultrasensitive sensing scheme at the terahertz frequencies with significantly enhanced sensitivity and an order of magnitude higher figure of merit compared to planar metasurfaces. Magnetic and electric resonant field enhancement in the impedance matched absorber cavity enables stronger interaction with the dielectric analyte. This finding opens up opportunities for perfect metamaterial absorbers to be applied as efficient sensors in the finger print region of the electromagnetic spectrum with several organic, explosive, and bio-molecules that have unique spectral signature at the terahertz frequencies.
The Impact of R&D Subsidy on Innovation: A Study of New Zealand Firms

This paper examines the impact of government assistance through R&D grants on innovation output for firms in New Zealand. Using a large database that links administrative and tax data with survey data, we are able to control for large number of firm characteristics and thus minimise selection bias. We find that receipt of an R&D grant significantly increases the probability that a firm in the manufacturing and service sectors applies for a patent during 2005–2009, but no positive impact is found on the probability of applying for a trademark. Using only firms that participated in the Business Operation Survey, we find that receiving a grant almost doubles the probability that a firm introduces new goods and services to the world while its effects on process innovation and any product innovation are relatively much weaker. Moreover, there is little evidence that grant receipt has differential effects between small to medium (
DETECTION OF CANCEROUS LESION BY UTERINE CERVIX IMAGE SEGMENTATION

This paper works at segmentation of lesion observed in cervical cancer, which is the second most common cancer among women worldwide. The purpose of segmentation is to determine the location for a biopsy to be taken for diagnosis. Cervix cancer is a disease in which cancer cells are found in the tissues of the cervix. The acetowhite region is a major indicator of abnormality in the cervix image. This project addresses the problem of segmenting uterine cervix image into different regions. We analyze two algorithms namely Watershed, K-means clustering algorithm, Expectation Maximization (EM) Image Segmentation algorithm. These segmentations methods are carried over for the colposcopic uterine cervix image.
Greenfield vs acquisitions: determinants of choice in emerging economies

This paper aims at finding the determinants of entry mode choices for MNCs that enter emerging economy nations as wholly owned subsidiaries. Existing literature suggests that this area of international business literature is relatively understudied and reasons for conducting more research exist. In this paper, I test three hypotheses using a logistic regression model. More specifically, this paper looks at the role of contributed assets; and organizational learning and experience in determining the choice between greenfield entry and acquisitions. The results suggest that host country experience and past entry experience has an impact on the current entry mode choice.
A 8x1 Sprout-Shaped Antenna Array with Low Sidelobe Level of -25 dB

This paper proposes a 8 × 1 sprout-shaped antenna array with low sidelobe level (SLL) for outdoor point to point applications. The array has the dimensions of 165 mm × 195 mm × 1.575 mm and is designed on Rogers RT/Duroid 5870tm with the thickness of 1.575 mm and permittivity of 2.33. In order to achieve low SLL, Chebyshev distribution weights corresponding to SLL preset at -30 dB has been applied to design the feed of the array. Unequal T-junction dividers have been used to ensure that the output powers are proportional to the Chebyshev amplitude distribution. A reflector has been added to the back of the antenna to improve the directivity. The simulated results show that the proposed array can work at 4.95 GHz with the bandwidth of 185 MHz. Moreover, it can provide the gain up to 12.9 dBi and SLL suppressed to -25 dB. A prototype has also been fabricated and measured. A good agreement between simulation and measurement has been obtained. It is proved that the array can be a good candidate for point to point communications.

The Moderating Effects of Job Satisfaction on the Relationship between Personality Traits and Customer-oriented Behavior in the Malaysian Health Tourism Industry

This paper aims to analyze the relationship between personality traits, customer-oriented behavior and job satisfaction. Focusing on the moderating role of job satisfaction in enhancing customer oriented behavior, the research was set in the context of Malaysian health tourism industry. The respondents consisted of nurses in health tourism hospitals in Malaysia. A quantitative cross sectional survey method was adopted, coupled with factor analysis and hierarchical regression analysis to analyze the collected data. The findings of this study revealed that extraversion and agreeableness were positively and significantly related to customer-oriented behaviour. Further, job satisfaction was found to be a quasi-moderator that interacted with extraversion to predict customer-oriented behavior. The findings of this research facilitate health tourism organizations to identify, recruit and train nurses who possess the right personality traits, structure the values of the organization and nurture a conducive work environment in order to maximize nurses’ job satisfaction that effectively improves their behavior towards customers and ultimately the performance of the firms.
Comparison of Lecture and Video Methods in Increasing Caregiver Knowledge in Treating Clients Halusination

Efforts to improve caregiver’s knowledge on hallucination is by providing an education the caregivers. Enhancing such knowledge can be carried out by different methods, include lecture and watching video methods. The purpose of the present research was to compare the effectiveness of lecture and watching video method in enhancing caregiver’s knowledge on hallucination. The research used a quasi-experiment method with a pretest and posttest group design, with the research sample was 60. The sampling technique used was a total sampling. The scores of caregiver’s knowledge were determined by a questionnaire of knowledge on hallucination that was self-developed by validity test (0.707) and reliability test (0.968). The data obtained was then tested by using Independent Sample T-test, Mann-Whitney test, and Wilcoxon test. The result of pretest of caregiver’s knowledge before the intervention showed that there was no difference between intervention and control group (p-value=0.624), while result of posttest of caregiver’s knowledge after the intervention showed that there was a significant difference between lecture group and video group (p-value=0.000). The research findings revealed that there was a significant increase in the scores of knowledge for both methods (p-value=0.000), but the increase of video group’s knowledge score was higher (4.23) than that of lecture group (2.57). The conclusion of the research was that wathing video method was more effective than lecture method in enhancing caregiver’s knowledge so that video can be used as an alternative method for mental health education.
Empirical Evaluation of a New Coupling Metric: Combining Structural and Semantic Coupling

Abstract Coupling, a measure of the interdependence among software entities, is an important property for which many software metrics have been defined. It is widely agreed that the extent of coupling in an object-oriented system has implications for its external quality. Structural and semantic relations between classes can be measured directly from static source code. However, both have limitations. In order to understand which aspects of coupling affect quality or other external attributes of software, this paper presents a new coupling metric for object-oriented systems that analyze structural and semantic relationships between methods and classes. The paper investigates the use of the new proposed coupling metric during change impact analysis, predicting fault-prone and maintainable classes. By comparing the new metric to other coupling metrics, we show that the new metric is a better predictor for classes impacted by changes. The new metric also shows good promise in predicting both external qualities (fault proneness and maintainability).
Stability of a Fuzzy Logic Based Piecewise Linear Hybrid System

Seyfried, Aaron. M.S.Egr. , Department of Electrical Engineering, Wright State University, 2013. Stability of a Fuzzy Logic Based Piecewise Linear Hybrid System. Complex cyber-physical systems are difficult to model and control. However, humans are capable of accomplishing these tasks by constantly adapting and redefining the rules to control these complex systems. Fuzzy logic provides a means of encoding human inference into a control methodology. However, the fuzzy logic controllers are nonlinear and their stability is difficult to verify. Therefore, the widespread usefulness of fuzzy logic controllers is limited. It has been proven that fuzzy logic controllers can be implemented as piecewise linear switched controllers. It has also been shown that the peicewise linear system can be implemented as a hybrid system. Piecewise linear hybrid system stability can be verified by extending the Lyapunov proof for one linear system to multiple decreasing Lyapunov functions. The objective of this thesis is to implement fuzzy logic control systems as a piecewise linear hybrid system and examine their stability. A proportional fuzzy logic controller with constant derivative gain is implemented as a piecewise linear hybrid system using Matlab Simulink Stateflow. Stability of the system is examined by obtaining the Lyapunov function of each subsystem and stitching them according to the fuzzy rules. It is shown that the stitching of Lyapunov functions must successively decrease for the system to be stable. Further implications of robustness are examined by varying the fuzzy logic rules and observing the effect on the corresponding stitched Lyapunov functions.
Hyperspectral optical analysis of Zumpango Lake, Mexico

This paper shows a hyperspectral optical analysis of Zumpango Lake, relict of one of the lakes that formerly filled the Basin of Mexico. The spectral signatures are do- minated by the presence of phytoplankton and submerged vegetation. Integrated spectral curves have a good statistical correlation with chlorophyll a concentration values. It in- dicates that submerged vegetation water, mainly hyacinth (Eichhornia spp) and duckweed (Lemna sp), and phyto- plankton are homogeneously distributed in the water body, which confers its characteristics of eutrophication.
