The unbearable opaqueness of Arp 220

We explore the potential of imaging vibrationally excited molecular emission at high angular resolution to better understand the morphology and physical structure of the dense gas in Arp~220 and to gain insight into the nature of the nuclear powering sources. Vibrationally excited emission of HCN is detected in both nuclei with a very high ratio relative to the total $L_{FIR}$, higher than in any other observed galaxy and well above what is observed in Galactic hot cores. HCN $v_2=1f$ is observed to be marginally resolved in $\sim60\times50$~pc regions inside the dusty $\sim100$~pc sized nuclear cores. Its emission is centered on our derived individual nuclear velocities based on HCO$^+$ emission ($V_{WN}=5342\pm4$ and $V_{EN}=5454\pm8$~\kms, for the western and eastern nucleus, respectively). With virial masses within $r\sim25-30$~pc based on the HCN~$v_2=1f$ line widths, we estimate gas surface densities (gas fraction $f_g=0.1$) of $3\pm0.3\times10^4~M_\odot~\rm pc^{-2}$ (WN) and $1.1\pm0.1\times10^4~M_\odot~\rm pc^{-2}$ (EN). The $4-3/3-2$ flux density ratio could be consistent with optically thick emission, which would further constrain the size of the emitting region to $>15$~pc (EN) and $>22$~pc (WN). The absorption systems that may hide up to $70\%$ of the HCN and HCO$^+$ emission are found at velocities of $-50$~\kms~(EN) and $6$, $-140$, and $-575$~\kms (WN) relative to velocities of the nuclei. Blueshifted absorptions are the evidence of outflowing motions from both nuclei. The bright vibrational emission implies the existence of a hot dust region radiatively pumping these transitions. We find evidence of a strong temperature gradient that would be responsible for both the HCN $v_2$ pumping and the absorbed profiles from the vibrational ground state as a result of both continuum and self-absorption by cooler foreground gas.
A Review of Security Challenges in Cloud Computing Adoption: A Conceptual Framework on Early Adopters of Cloud Computing as a Technology Model

Cloud computing is developing as an efficient and viable model of delivering IT services. The challenges posed to-date by security are not to be underestimated with regard to cloud computing adoption. The study assesses the security challenges associated with cloud computing adoption and proposes a framework to assist early adopters of the technology model to address them. Various sections of the literature have indicated that security challenges are a great source of concern in the adoption and usage of cloud computing, and a comprehensive framework is vital to assess previous studies conducted in this area. This study would like to propose viable mechanisms to address these challenges. The study surveyed 380 participants in Gauteng, South Africa to assess the level of agreement and disagreement about the security challenges in cloud computing. The study used a quantitative method to analyse the
Associations among adolescents’ health-risk behavior, their perceptions of their friends’ health-risk behavior, parental support and school support within the context of a school transition.

ASSOCIATIONS AMONG ADOLESCENTS’ HEALTH-RISK BEHAVIOR, THEIR PERCEPTIONS OF THEIR FRIENDS’ HEALTH-RISK BEHAVIOR, PARENTAL SUPPORT AND SCHOOL SUPPORT WITHIN THE CONTEXT OF A SCHOOL TRANSITION by LaTasha McKenzie Mack Within the context of transitioning from a smaller to a larger school setting, adolescents’ selfreported health-risk behavior and academic achievement were examined in relation to their perceptions of their friends’ health-risk behavior and parent and school support. Hypotheses were generated using the “windows of vulnerability” (Lau Quadrel, & Hartman; 1990) and the “stage-environment fit” (Eccles, Lord, & Midgley; 1991) models. Previous health-risk behavior, friends’ health-risk behavior, parent support and the interaction term parent support by academic achievement were predictive of adolescents’ current health-risk behavior. In general, adolescents with low support and academic achievement participated more in health-risk behavior. Suggestions for prevention and intervention programs are offered.

View to the future: could genomic evaluation become the standard?

Genomic selection means marker assisted selection based on a panel of markers that cover the genome so densely that every quantitative trait locus (QTL) is in linkage disequilibrium with at least one marker (Meuwissen et al. 2001). Genomic evaluation is the calculation of estimated breeding values (EBVs) based on this marker data. The main requirement for genomic selection is a ‘reference population’ consisting of animals that have been evaluated for the trait, genotyped for the markers and from which an equation to predict breeding value from genotypes can be derived. This prediction equation can then be applied to animals that have only DNA marker genotypes but no phenotype or offspring. This allows selection to be combined with short generation intervals and hence achieve faster genetic improvement.
Radiochemical analysis of a copper beam dump irradiated with high-energetic protons

Abstract The radionuclide inventory of a copper beam dump from the 590 MeV proton accelerator of the Paul Scherrer Institute in Switzerland was determined, focusing on radioisotopes with half-lives of more than 60 d, and in particular, of long-lived isotopes with T1/2=104−107 years, which are important regarding radioactive waste management. The measurements were carried out using high resolution γ-measurement without sample destruction, as well as liquid scintillation counting (LSC) and accelerator mass spectrometry (AMS) after chemical separation. For the first time, a beam dump from a high power accelerator facility was completely characterized concerning the depth and radial distribution profile of the most hazardous and/or long-lived radionuclides. Moreover, it turned out that some of the investigated radionuclides, like for instance 26Al, 44Ti or 60Fe represent valuable material for application in several scientific fields like nuclear astrophysics, basic nuclear physics research, radiopharmacy and many others. Therefore, based on the analytical results, a special research and development program has been started at PSI objecting on specific preparative extraction of long-lived radioisotopes (ERAWAST — exotic radionuclides from accelerator waste for science and technology).
SECURE DATA ACCESS USING BIOMETRIC RECOGNITION IN CLOUD COMPUTING

-The personal data stored in the cloud may contain account numbers, passwords, notes, and other important information that could be used and misused by a miscreant, a competitor, or a court of law. These data are cached, copied, and archived by Cloud Service Providers (CSPs), often without user’s authorization and control. Self-destructing data mainly aims at protecting the user data’s privacy. All the data and their copies become destructed or unreadable after a user-specified time, without any user intervention. In addition, the decryption key is destructed after the user-specified time. In the proposed system, SeDas, a system that meets this challenge through a novel integration of cryptographic techniques with active storage techniques based on T10 OSD standard. In the proposed system, user’s biometric information are encrypted and stored in a database. Batch homomorphic encryption technique is used to encrypt the biometric information provided by user biometric information and are compared with the database where the authenticated user’s encrypted information are stored. User’s fingerprints are encrypted by batch homomorphic encryption technique. The biometric information is decrypted and the user is subscribed to access the cloud. This decides whether the user is approved or denied. Once the user is recognized as an authorized user, the user can view, upload or download the data stored in cloud.

Disciplinary Differences in Engineering Students' Aspirations and Self-Perceptions

In discussions of the recruitment and retention of engineering majors, students are sometimes treated as a homogeneous group with respect to the necessary preparation for college, their career values, and their aspirations despite the diversity of opportunities and specialties across disciplines. Moreover, initiates just starting their post-secondary education in engineering may not perceive disciplines as practitioners do: they may identify and find affinity for features of an engineering specialty that may be different from actual practice. This paper conducts a comparative analysis of students at the start of their engineering studies using data drawn from a nationally-representative survey, conducted in 2011, of 6772 students enrolled at 50 colleges and universities in the U.S. By identifying students intending to major in eight different disciplines (bio-, chemical, civil, electrical/computer, environmental, industrial/systems, materials, and mechanical engineering), we show how student goals, values and self-perceptions differ. Regression analysis is used to study how the likelihood of entering one of these eight disciplines is associated to career outcome expectations, students' self-beliefs around their science, physics, and math identities, and constructs measuring their personal and global science agency. Results indicate that students intending to major in engineering show substantial interdisciplinary distinctions in the investigated domains. The utility of this work is that it should help to guide more effective recruiting of students into engineering disciplines and allow for a broadening of recruitment efforts to students who would normally be overlooked for engineering careers.
Propagation of Photon in Multilayer Anisotropic Metamaterials

We present a theoretical study of the propagation properties of polarized photons transmitting through a multilayer cavity with anisotropic metamaterials. We find that there are the resonant peaks of transmission appearing for photons polarized in a certain direction transmitting through the cavity with the anisotropic metamaterials having negative elements of the permittivity tensor. The resonant peak of transmission for photons can be achieved by adjusting the thicknesses of the cavity. The frequency of the resonant peak moves to the lower frequency as the thickness of the cavity which is the air in our designed structure increasing for a three layer cavity. The result also shows that we can adjust the resonant peak through changing the layer number. Increasing the layer number the more resonant peaks appear. The three layer system has one resonant peak. The five layer system has two resonant peaks and the seven layer system has three resonant peaks. The cavity number which also is the number of the air layer decides the resonant peaks. Increasing the cavity thickness the space of the resonant peaks will decrease. For a three layer cavity, the resonant peak will appear to a certain cavity thickness when we keep the frequency of the input photon as a constant. As the frequency of the input photon becomes bigger the thickness of the cavity corresponding to the resonant peak becomes smaller. At the same time the resonant peak becomes sharp. The result shows that the transmission is almost invariant with the changing of the thickness of the anisotropic metamaterials. This means the resonant peak is insensitive to the thickness of the anisotropic metamaterials. So the thickness of the cavity (air) is important to the design of the cavity structure. These conclusions will give us some instructions to the design of the cavity structure with the anisotropic metamaterials. The cavity structures with the anisotropic metamaterials have the potential for applying such as filters for photons with certain polarizations.
A System for Recommending Rental Properties

This paper presents an implementation of recommender technology to online search of rental properties. In particular, the paper uses the preference-based search approach combined with a technique called example-critiquing. Rather than perform a query against the database, this approach prompts the user to express some preferences on rental properties, uses them to construct a preference model for the user, and finally generates a list of properties that best match that preferences. The system is developed as Web application using the Ruby on Rails framework.

Plasmonic Circular Nanostructure for Enhanced Light Absorption in Organic Solar Cells

This study attempts to enhance broadband absorption in advanced plasmonic circular nanostructures (PCN). Experimental results indicate that the concentric circular metallic gratings can enhance broadband optical absorption, due to the structure geometry and the excitation of surface plasmon mode. The interaction between plasmonic enhancement and the absorption characteristics of the organic materials (P3HT:PCBM and PEDOT:PSS) are also examined. According to those results, the organic material's overall optical absorption can be significantly enhanced by up to ~51% over that of a planar device. Additionally, organic materials are enhanced to a maximum of 65% for PCN grating pitch = 800 nm. As a result of the PCN's enhancement in optical absorption, incorporation of the PCN into P3HT:PCBM-based organic solar cells (OSCs) significantly improved the performance of the solar cells: short-circuit current increased from 10.125 to 12.249 and power conversion efficiency from 3.2% to 4.99%. Furthermore, optimizing the OSCs architectures further improves the performance of the absorption and PCE enhancement.
The Mediating Effect of Consumers' Purchase Intention: A Perspective of Online Shopping Behavior among Generation Y

Young consumers spend most of their time online in comparison to the working adults due to their great potential of buying power as well finding that online shopping is more convenient. The objective of this study is to investigate factors determining online purchase intention among the university students whereby variables such as attitude, subjective norm, trust, purchase intention and behavior were tested. Total of 800 questionnaires were distributed and 662 questionnaires were usable. A quantitative research was undertaken through the distribution of survey questionnaires and the data were analyzed using Structural Equation Modelling (SEM) to test the relations among variables. The analyses have proven that purchase intention has functioned effectively as a mediator between the independent variables (attitude, subjective norm and trust) and dependent variables (online shopping behavior). The results of this study offer some new frontiers in supporting as well as enriching more studies in the scope of online shopping behaviors. This study contributes to the dynamics of the causative relations between examined variables and highlights the significance of attitude, subjective norm, trust and consumer behavior in ascertaining the purchase intention in the context of Malaysian online purchases.

DUAL MODE RESONANT CONVERTER FOR INDUCTION HEATING SYSTEM

I. INTRODUCTON Induction heating(IH) technology is commonly used in domestic applications because of its cleanliness, faster heating process and high efficiency.Induction heating (IH) is a non-contact heating process, it uses high frequency electricity to heat materials that are electrically conductive. Where the pot is directly heated by the induced currents generated with a varying the magnetic field in the range of 20-100 kHz. This magnetic field is generated by an inductor coil system supplied by a resonant power converter. In resonant converters higher output power occurs at resonant frequency, yielding efficiency is also high. The conventional series half-bridge ZVS resonant inverter is also used for the IH application. In this converter,The resonance frequency is higher than the switching frequency, yielding to the maximum efficiency at the maximum output power. Whereas if the switching frequency is higher than the resonant frequency. Thus with the increased switching frequency the losses are increased for the low output power range [2],[3]. To overcome this limitation, a dual mode operation of resonant converter is discussed in ref. [6]. This paper presents the simulation of dual mode resonant converter for induction heating system. The main advantage of this converter is to improve the efficiency even at the low output power range byreducing switching losses. MATLAB/SIMULINK is used for simulation studies.
Women's Experiences of Victimization and Survival

In an effort to more fully understand the experiences and aftermath of girlhood and adult woman physical, sexual and psychological victimization, research was undertaken that explored the prevalence and the consequences of such victimization, and the survival strategies women activate at various points in their lifespan in the aftermath of that violence. Women participants were recruited from five different communities; three urban, one rural and the only correctional facility for women in a Midwestern state. These venues were selected as ideal sites in which to secure a racially, ethnically and geographically diverse sample of women age 18 and older. Findings yielded from the total sample of 423 women reveal a significantly high rate of multiple types of victimization amongst the entire sample population. Certain health and mental health-related adult outcomes for these women are reported, as are the relationships between the types of victimization experienced and those adult outcomes and the influence of certain factors on those adult outcomes. Finally, women's experiences using and evaluating the helpfulness of a variety of services post-victimization are presented.
