Late-time Observations of the Type Ia Supernova SN 2014J with the Hubble Space Telescope Wide Field Camera 3

Recent works have studied the late-time light curves of Type Ia supernovae (SNe Ia) when these were older than 500 days past B-band maximum light. Of these, SN 2014J, which exploded in the nearby galaxy M82, was studied with the Advanced Camera for Surveys onboard the Hubble Space Telescope (HST) by Yang et al. Here, I report complementary photometry of SN 2014J taken with the HST Wide Field Camera 3 when it was ∼360–1300 days old. My F555W measurements are consistent with the F606W measurements of Yang et al., but the F438W measurements are ∼1 mag fainter than their F475W measurements. I corroborate their finding that, even though SN 2014J has spatially resolved light echoes, its photometry is not contaminated by an unresolved echo. Finally, I compare the F438W and F555W light curves of SN 2014J to those of the other late-time SNe Ia observed to date and show that more intrinsically luminous SNe have slower light curve decline rates. This is consistent with the correlation claimed by Graur et al., which was based on a comparison of pseudo-bolometric light curves. By conducting a direct comparison of the late-time light curves in the same filters, I remove any systematic uncertainties introduced by the assumptions that go into constructing the pseudo-bolometric light curves, thus strengthening the Graur et al. claim.
Current Progress on MicroRNA-Based Gene Delivery in the Treatment of Osteoporosis and Osteoporotic Fracture

Emerging evidence demonstrates that microRNAs, as important endogenous posttranscriptional regulators, are essential for bone remodeling and regeneration. Undoubtedly, microRNA-based gene therapies show great potential to become novel approaches against bone-related diseases, including osteoporosis and associated fractures. The major obstacles for continued advancement of microRNA-based therapies in clinical application include their poor in vivo stability, nonspecific biodistribution, and unwanted side effects. Appropriate chemical modifications and delivery vectors, which improve the biological performance and potency of microRNA-based drugs, hold the key to translating miRNA technologies into clinical practice. Thus, this review summarizes the current attempts and existing deficiencies of chemical modifications and delivery systems applied in microRNA-based therapies for osteoporosis and osteoporotic fractures to inform further explorations.
ELECTRICAL CHARACTERIZATION OF ADSORBENT FILMS FOR VOC´S DETECTION

O principal objetivo desse trabalho e a caracterizacao eletrica de filmes finos de HMDS e/ou fluorados depositados por plasma como camada dupla ou composito. Os filmes foram depositados em lâminas de silicio utilizando um equipamento de plasma DC totalmente fabricado em laboratorio. As medidas de caracterizacao eletrica foram realizadas variando-se a capacitância em funcao da tensao e exposicao dos filmes a um fluxo de ar contaminado com vapores de 2-propanol ou n-hexano. A capacitância do filme de HMDS variou devido a exposicao, porem teve uma facil recuperacao parcial usando fluxo de ar. O filme fluorado mostrou baixa sensibilidade e o de camada dupla mostrou retencao devido a permeacao do reagente no filme fluorado. O filme composito mostrou interacao intermediaria e a possivel recuperacao do valor da capacitância. Entretanto, os filmes de HMDS e fluorados sao promissores no desenvolvimento de sensores. No entanto, enquanto os filmes de HMDS parecem ser uteis em qualquer tipo de sensores capacitivos; devido a dificil recuperacao do sinal, os fluorados sao mais adequados em sensores de “mao unica”.

Arabic Question Answering: A Study on Challenges, Systems, and Techniques

The enormous increase of the amount of information available on the web creates the need for systems like Question Answering to bridge the gap between general end users and the web with its different data representations. A considerable portion of the available data on the web is written in Arabic for and by Arabic users. This paper provides a review of the Arabic Question Answering Systems building processes and the challenges met by the researchers in this topic due to the Arabic language special characteristics. A general architecture is represented for the Question Answering task on both structured and unstructured data. Then, an overview of the work done in Arabic Question Answering Systems is presented. Finally, a number of tools and linguistic resources are recommended for researchers to develop Arabic question answering systems.
Genetic Diversity of Clinal Freezing Tolerance Variation in Winter Wheat Landraces

Wheat (Triticumaestivum L.) is a major cereal crop grown across a wide range of environments, but its productivity around the world is challenged by various biotic and abiotic factors. Wheat landraces from around the world are a source of unexploited genetic diversity that can be essential for modern wheat-breeding programs in search of resistance to abiotic stresses like freezing tolerance. This genetic diversity study of 553 winter wheat landraces based on single-nucleotide polymorphisms (SNPs) revealed separate clusters of landraces related to the latitude of origin. Linkage block analysis revealed genomic regions with specific alleles skewed towards landraces from higher latitudes, suggesting that migration to higher latitudes resulted in the fixing of specific alleles. Electrolyte leakage was used to measure the tolerance of freezing to −14 °C, −16 °C, and −18 °C of 192 landraces. There was a significant negative correlation between latitude and electrolyte leakage, with an R2 value of 0.14, (p < 0.0001), in a regression analysis indicating greater freezing tolerance in landraces from higher latitudes. Genome-wide association studies identified regions in chromosomes 4A and 6A associated with higher latitudes and freezing tolerance, respectively. Landraces with freezing tolerance may be useful in developing new germplasm as novel sources of greater cold hardiness.

Post-exit loyalty : exploring the phenomenon, scale developing & testing its predictive value

Alvesson (2000) described people who still feel attached to their former employer even after leaving. He labelled this phenomenon post-exit loyalty. This phenomenon is believed to have significant implications for the knowledge intensive industry in which networks and interorganizational linkages are crucial (Alvesson, 2000). So far prior research lacks empirical evidence of this phenomenon. There is no clear definition of the construct and no measurement is available. This study offered a first approach to explore phenomenon of post-exit loyalty. This research was divided in two studies: study 1, qualitative and study 2, quantitative. The purpose of these studies was to explore the post-exit relations between ex-employers and their ex-organizations. The objectives of the first study were: what is going on in this post-exit relationship and what are the affects of ex-employees towards their former organization. In order to reach these objectives, this study followed a qualitative approach, designed with multiple focus groups using an online electronic chat tool, MSN Web Messenger. 19 ex-employees of 7 organizations voluntarily participated in 7 chatsessions. Of these 7 sessions, 5 were based on a predetermined similar characteristic: tenure (short and long period), time-elapse after exit (short and long period) and the current position of the freelancer, and 2 “mixed” chats. Also (limited) data as collected from management perspective (2 managers from 2 organizations). Out of the qualitative analysis, two general categories of affects were identified: positive and negative affects towards former employer, and a more instrumental attachment to the former employer. Furthermore, the analysis revealed ex-employees benefiting the former employer from a mutual perspective: ex-employees should also benefit. Results also revealed a change over time: affects neutralize. The second study followed a quantitative approach. The purpose of this study was to develop a measure for the post-exit loyalty construct, validate it and to explore its consequences. The objectives of this study were: how can post-exit loyalty be measured and how predictive are its consequences. To reach these objectives, this second study included an online survey with a sample of 153 respondents of six Dutch consultancy organizations.
Cukurova Medical Journal Ultrasound Study of Tubercular Lymphadenopathy Tüberküler Lenfadenopatide Ultrasound Çalışması

Tubercular lymphadenopathy is a common entity. Etiologically it can be divided into primary tubercular lymphadenopathy and secondary tubercular lymphadenopathy. Ultrasound can satisfactorily demonstrate the involved lymph nodes. Hence we reviewed the ultrasound findings in all fine needle aspiration cytology proven cases of tubercular lymphadenopathy that presented in the imaging department in the last 12 months. Nine different criteria on Grey Scale ultrasound imaging and three different criteria on Color Doppler ultrasound imaging were used to different tubercular nodes from metastatic lymphadenopathy. Matting, presence of intranodal necrosis-caseation, intranodal calcifications, minimal vascularity and reduced Doppler Pulsatility and Resisitivity Indices were the hallmarks of tubercular lymphadenopathy which enabled correct diagnosis with a sensitivity of 85.25% and a specificity of 98.36 %. Thus ultrasound can satisfactorily differentiate between tubercular and metastatic lymphadenopathy.
A preliminary report on the phylogeny of five balistid fish in terms of several chromosome banding techniques in combination with a statistical analysis.

Intervening C-band positive-G-band negative regions were observed just adjacent to the secondary constrictions on the largest acrocentric chromosome pair of Odonus niger and Meliehthys vidua, which intensely indicate the occurrence of tandem translocation event. Since the karyotypes of the five balistid fish studied comprised solely acrocentrics, the karyotypic changes by the tandem translocation could be used to precisely analyse their phyletic genetic evolution.
Production of Wind Energy and Agricultural Land Values: Evidence from Pennsylvania

Given the push toward renewable and alternative energy, a new energy mix is emerging. Wind is the fastest growing source of renewable electricity in the United States. The siting of wind turbines has proven controversial with multiple operations facing local resistance. Opponents cite issues such as noise, bird deaths, and aesthetics. Given that farmer portfolios are heavily comprised of land assets, the possibility that surrounding wind energy operations may reduce agricultural land value is of concern. This study examines that possibility using a hedonic regression analysis comparing per acre land value to a series of land characteristics and distance variables for Somerset County, PA. Results indicate no significant relationship between the presence of wind turbines and the value of agricultural land. This confirms the findings of similar studies which have examined the same relationship.
Runtime Object Lifetime Profiler for Latency Sensitive Big Data Applications

Latency sensitive services such as credit-card fraud detection and website targeted advertisement rely on Big Data platforms which run on top of memory managed runtimes, such as the Java Virtual Machine (JVM). These platforms, however, suffer from unpredictable and unacceptably high pause times due to inadequate memory management decisions (e.g., allocating objects with very different lifetimes next to each other, resulting in severe memory fragmentation). This leads to frequent and long application pause times, breaking Service Level Agreements (SLAs). This problem has been previously identified, and results show that current memory management techniques are ill-suited for applications that hold in memory massive amounts of long-lived objects (which is the case for a wide spectrum of Big Data applications). Previous works reduce such application pauses by allocating objects in off-heap, in special allocation regions/generations, or by using ultra-low latency Garbage Collectors (GC). However, all these solutions either require a combination of programmer effort and knowledge, source code access, offline profiling (with clear negative impacts on programmer's productivity), or impose a significant impact on application throughput and/or memory to reduce application pauses. We propose ROLP, a Runtime Object Lifetime Profiler that profiles application code at runtime and helps pretenuring GC algorithms allocating objects with similar lifetimes close to each other so that the overall fragmentation, GC effort, and application pauses are reduced. ROLP is implemented for the OpenJDK 8 and was evaluated with a recently proposed open-source pretenuring collector (NG2C). Results show long tail latencies reductions of up to 51% for Lucene, 85% for GraphChi, and 69% for Cassandra. This is achieved with negligible throughput (< 6%) and memory overhead, with no programmer effort, and no source code access.
Vulnerable Narcissism and First-Person Singular Pronoun Use

Who talks about themselves most frequently? Recent research has explored the top correlates of self-focused language use. Depression and negative emotionality tend to appear as key positive correlates. Surprisingly, narcissism—which is largely known for its trait of self-centeredness—is not a major correlate of self-focused language use. Studies demonstrating this null effect have only measured grandiose narcissism, while entirely neglecting vulnerable narcissism. By using a survey methodology with carefullyselected trait inventories and a language task, the purpose of this study is to fill the gap in the literature—to see whether vulnerable narcissism accounts for talking about oneself, above and beyond the common correlates of depression and negative emotionality. Our findings from a large number of college students (valid N = 471) indicated that vulnerable narcissism is significantly positively correlated with first-person singular pronoun use; however, it does not predict the outcome above and beyond traditional predictors. Along with establishing this novel correlation, these findings have clear practical implications which will be detailed further in this paper.

Affective Content Classification using Convolutional Neural Networks

We present a three-layer convolutional neural network for the classification of two binary target variables ’Social’ and ’Agency’ in the HappyDB corpus exploiting lexical density of a closed domain and a high degree of regularity in linguistic patterns. Incorporating demographic information is demonstrated to improve classification accuracy. Custom embeddings learned from additional unlabeled data perform competitive to established pre-trained models based on much more comprehensive general training corpora. The top-performing model achieves accuracies of 0.90 for the ’Social’ and 0.875 for the ’Agency’ variable.
Spatial Priming in Temporally Close Pairs

Previous studies deconfounding spatial and temporal proximity during map learning have found a temporal influence on mental map organization. The authors explored whether this observed priming effect reflected the manner in which a map was learned by having people either name objects or point to them during learning. Naming objects resulted in temporal organization but pointing to objects resulted in spatial organization, suggesting that mental map organization is sensitive to emphasizing different types of map information during learning. The authors also explored whether the temporal organization observed in the naming group was influenced by the ease of using spatial information during learning, such as when the expectancy to use spatial information was made explicit or when a consistent temporal order was absent. When naming map objects, evidence for a spatial organization was weak, whereas a temporal organization was observed when a consistent temporal order was present.
Supporting Teacher Leadership in Nevada

Nevada Context • The majority of teachers in Nevada were prepared out-of-state. • Nevada System of Higher Education (NSHE) reported that for the 2016-17 academic year, 58.6 percent of statewide demand for teachers was met by program completers from NSHE institutions. • NSHE estimates that roughly 60 to 73 percent of graduates from education programs at NSHE institutions remain in the profession after five years.
Assessment of dam construction impact on hydrological regime changes in lowland river – A case of study: the Stare Miasto reservoir located on the Powa River

Abstract The purpose of the presented research is analysis and assessment of the Stare Miasto reservoir impact on the hydrological regime changes of the Powa River. The reservoir was built in 2006 and is located in the central part of Poland. The total area of inundation in normal conditions is 90.68 ha and its capacity is 2.159 mln m3. Hydrological regime alteration of the Powa River is analysed on the basis of daily flows from the Posoka gauge station observed during period 1974–2014. Assessment of hydrological regime changes is carried out on the basis of Range of Variability Approach (RVA) method. All calculations are made by means of Indicators of Hydrologic Alteration (IHA) software version 7.1. 0.10. The analysis shows that the Stare Miasto reservoir has a moderate impact on hydrological regime of the Powa River. Construction of the reservoir has positive effect on stability of minimal flows, which are important for protection of river ecosystems. The results obtained indicate that the Stare Miasto reservoir reduces a spring peak flow and enables to moderate control of floods.
Measuring Core Inflation by Multivariate Structural Time Series Models

The measurement of core inflation can be carried out by optimal signal extraction techniques based on the multivariate local level model, by imposing suitable restrictions on its parameters. The various restrictions correspond to several specialisations of the model: the core inflation measure becomes the optimal estimate of the common trend in a multivariate time series of inflation rates for a variety of goods and services, or it becomes a minimum variance linear combination of the inflation rates, or it represents the component generated by the common disturbances in a dynamic error component formulation of the multivariate local level model. Particular attention is given to the characterisation of the optimal weighting functions and to the design of signal extraction filters that can be viewed as two sided exponentially weighted moving averages applied to a cross-sectional average of individual inflation rates. An empirical application relative to U.S. monthly inflation rates for 8 expenditure categories is proposed

Food Swamps and Poor Dietary Diversity: Longwave Development Implications in Southern African Cities

While the literature on food deserts focuses on limited availability of food in urban settings, ‘food swamps’ may better characterize the extensive prevalence and accessibility of cheap, highly processed foods. For urban populations, access to nutritionally inadequate poor-quality food has dire developmental consequences. The long-wave impacts of malnutrition at gestational and early childhood stages are negative and can be non-reversible. Moreover, those who survive into adulthood may face a lifetime of sub-optimal physical and mental development that undermines the second and third UN Sustainable Development Goals—to end hunger and to ensure healthy lives. This paper assesses the long-term health vulnerability of children with limited access to adequate and nutritious food in rapidly urbanizing cities. The analysis focuses on the African Urban Food Security Network (AFSUN) data drawn from 6453 household surveys in 11 cities and nine countries in Southern Africa. The results indicate that children in these households are consuming a limited diversity of food, have limited access to resources and have greater odds of experiencing both short-term and long-term food and nutrition insecurity. These findings demonstrate an underlying vulnerability to long-term health impacts stemming from nutritionally inadequate diets, with potentially significant costs to human capital.
USING A COMPUTER AND THE ROLE OF COMPUTER PROGRAMS IN TEACHING ENGLISH TO PRESCHOOLERS.

: This article is about the role of multimedia, especially computers, in teaching young learners. Because children can learn everything easily with the help of multimedia technologies. These statements indicate that the desire to succeed (even if virtual), the ability to concentrate, repeat, remember, formulate a problem and find its solution has moved for children to the field of work on a computer.
