Starburst-AGN mixing-I. NGC 7130

We present an integral field spectroscopic study of the Luminous Infrared Galaxy (LIRG) NGC 7130, a known starburst-AGN composite galaxy. We employ standard emission line ratio diagnostics and maps of velocity dispersion and velocity field to investigate how the dominant ionising sources change as a function of radius. From the signatures of both star formation and AGN activity we show that NGC 7130 is a remarkably clean case of starburst-AGN mixing. We find a smooth transition from AGN dominated emission in the centre to pure star forming activity further out, from which we can estimate the radius of the extended narrow line region to be 1.8 +/- 0.8 kpc. We calculate that the fraction of [OIII] luminosity due to star formation and AGN activity is 30 +/- 2% and 70 +/- 3% respectively, and that the fraction of H-alpha luminosity due to star formation and AGN activity is 65 +/- 3% and 35 +/- 2% respectively. We conclude with a discussion of the importance and potential of starburst-AGN mixing for future studies of the starburst-AGN connection.
On the trophic fate of Phaeocystis pouchetii. VII. Sterols and fatty acids reveal sedimentation of P. pouchetii-derived organic matter via krill fecal strings

As part of a joint project on the fate of phytoplankton in Balsfjorden in Northern Nor- way, we investigated the trophic fate and sedimentation potential of Phaeocystis pouchetii by tracing the transition of biomarker patterns from a phytoplankton bloom to sediment traps and during a gut- passage experiment. The phytoplankton biomass during the spring bloom 1996 was dominated by colonial P. pouchetii (ca 85%) and 4 members of the diatom family Thalassiosiraceae (ca 10%). Par- ticulate organic carbon in sediment traps largely consisted of fecal material from the Arctic krill Thysanoessa sp. Sterol and fatty acid biomarker patterns in the phytoplankton bloom could be repro- duced by combining the individual biomarker patterns of the isolated phytoplankters P. pouchetii and Thalassiosira decipiens in a ratio of ca 75:25. In a laboratory experiment, Arctic krill (Thysanoessa raschii) fed with similar efficiency on P. pouchetii colonies and the Thalassiosiraceae. During gut passage, the abundance of Thalassiosiraceae biomarkers in fecal strings increased relative to P. pouchetii biomarkers, while biomarkers from krill became dominant. This transition of biomarker patterns due to gut passage in T. raschii closely resembled the biomarker transition from the surface bloom to material in sediment traps at 40 to 170 m depth, which was mainly composed of krill fecal strings. We conclude that krill grazed efficiently on P. pouchetii colonies in Balsfjorden and caused sedimentation of P. pouchetii-derived organic matter below the euphotic zone via fecal strings. Hence, both transfer to higher trophic levels and sedimentation of Phaeocystis spp. -derived organic matter can be more effective than is commonly believed.
Indirect Effects of FNE and POP on Emotional Exhaustion: The Role of Facades of Conformity

Facades of Conformity are termed as false representations created by employees to appear as if they embrace organizational values. The phenomenon demonstrates that apparent value congruence does not imply actual value congruence. Analysis of data from 322 employees of 4 services sector organizations situated in Rawalpindi and Islamabad, using Structural Equation Modelling technique, revealed that Fear of Negative Evaluation (FNE) and Perception of Politics (POP) are possible predictors of facade creation, which leads to emotional exhaustion. Evidence suggests that facade creation also mediates the relationships of fear of negative evaluation and perception of politics with emotional exhaustion. Drawing on the findings, we discussed some theoretical and practical implications. We also discussed some limitations and future directions in the end.
Invasion success despite reduction of genetic diversity in the European populations of eastern mosquitofish (Gambusia holbrooki)

The introduction of a few individuals to new, isolated habitats (founder effect) is expected to reduce the genetic variability of a population. At the beginning of the last century a few eastern mosquitofish (Gambusia holbrooki) individuals were introduced to Southern Europe from North America to control malaria‐carrying mosquitoes. We studied the effect of this severe bottleneck on genetic variability in four populations of eastern mosquitofish introduced to Spain and Italy in the early 1900s and compared them to a native population in North America. Using amplified polymorphic DNA–polymerase chain reaction (RADP–PCR) we found a strong reduction of genetic diversity, in terms of both number of polymorphic loci and heterozygosity, in all four European populations. Despite this great reduction in genetic diversity, eastern mosquitofish successfully invaded European internal waters causing eutrophication problems and threatening the extinction of local populations of native fish.
26S: Novel reference gene from leaves and roots of common bean for biotic stress expression expression studies based on PCR

The aim of this study was to evaluate the variation in the expression levels of five traditional housekeeping genes under contrasting conditions of abiotic stress to identify the most stable reference gene. In the evaluation of expression levels by RT-PCR, the gene with less variation among cultivars and treatments was the ribosomal 26S. Regarding to the variation between foliage and root tissues the more stable genes were â-tubulin and 26S, while between phenological stages the best were 26S and the 1-â elongation factor. The evaluation of expression levels by absolute qPCR confirmed that the 26S gene is a stable reference for the study of gene expression based on the PCR technique due to its low coefficient of variation through contrasting abiotic stress conditions.
Culture and Identity in Public Green Spaces: The Story of Suropati and Menteng Park in Central Jakarta, Indonesia

Changing the role of parks and green spaces to fit into the sustainable city framework are now an ongoing agenda for city planners worldwide. One popular concept is how green spaces promote urban liveability and sociability among city dwellers. While parks provide environmental benefits, parks are also public spaces that come with historical heritage, culture and social identity of the urban residents. This paper explores the subjectivity of urban life collected from the perspectives of different individuals on how they engage with the conception of living in a megacity and park use. Case study sample selected for this research takes place in Menteng sub-district where the first and oldest urban park located in the Special Capital District of Jakarta Central, Indonesia. The discussion that follows takes three central stories of different themes: 1.the city’s relation to memory and perception, 2. Influence of urban life to changing tradition and culture 3. The role of the people in everyday makings of the city. The results presented demonstrate the different styles of meaningful interactions with others within the park, the different “spatial story” to tell within the larger social order of urban life in Jakarta.
The Industrial Development of Western China in the First 5 years of Western Development Program

Since 1999, China launched the program of western development and began to implement a series of development plans in 2000. As the economic base, industrial sectors are one of the development focuses of the program. An important policy measure in the program is to increase investment. As we know, investment, especially government investment, has been the main source maintaining China’s high speed growth for a long time. Investment growth causes fast capital accumulation and then scale expansion of industries. However, capital productivity decides the impact of investment on promoting economic growth. Investing in low productivity sectors will not only waste capital, but also accumulate economic risk. Recently, China has realized that high inputs and relative low income are not a recipe for a sustainable growth mode. It’s important to improve industries’ productivity to grow more efficiently.
DG Allocation Based on Reliability, Losses and Voltage Sag Considerations: an expert system approach

Expert System (ES) as a branch of Artificial Intelligence (AI) methodology can potentially help in solving complicated power system problems. This may be more appropriate methodology than conventional optimization techniques when contradiction between objectives appears in reaching the optimum solution. When this contradiction is the hindrance in reaching the required system operation through the application of traditional methods ES can give a hand in such case. In this paper, the knowledge- based ES technique is proposed to reach near-optimum solution which is further directed to the optimum solution through particle swarm optimization (PSO) technique. This idea is known as Hybrid-Expert-System (HES). The proposed idea is used in getting the optimum allocation of a number of distributed generation (DG) units on Distribution System (DS) busbars taking into consideration three issues; reliability, voltage sag, and line losses. Optimality is assessed on the economic basis by calculating money benefits (or losses) resulting from DG addition considering the three aforementioned issues. The effectiveness of the proposed technique is ascertained through example.
How Does the Experience of Social Power Affect the Amount of Facebook Activity

Our study sought to reveal whether social power affects Facebook behaviour in a similar manner that it affects behaviour in the real world. We predicted that participants in the high power condition would be more active on Facebook compared to both low power and control conditions, while low power participants would be less active on Facebook. Participants in the experimental condition went through a double manipulation of heightened or lowered social power and were instructed to login on Facebook and use it for five minutes afterwards. A self-report questionnaire was presented after the Facebook task in order to measure the amount of messages, comments, posts, reactions, and shares participants made on Facebook. The total amount of Facebook activity was compared between the groups, however, no significant results were discovered. Methodological limitations and suggestions for future research are discussed.

Facets of Estrus Behavior in Surti Buffaloes

The Investigation was undertaken on sixteen healthy Surti buffaloes to document and characterize female sexual/estrus behavior in Surti buffaloes maintained at Livestock Research Station, Navsari Agricultural University, Navsari, Gujarat. Perusal of data revealed that in about 56.25 per cent of animals showed estrus during morning while remaining 42.75 percent in the evening time. Result of this study indicated that restlessness, frequent urination and sniffing of vagina, chin resting, chasing, bellowing, being mounted by others, mounting others and tail raising was the estrus specific signs in Surti buffaloes. The overall estrus duration, onset of estrus to ovulation and estrus duration after end of estrus were 22.19 ± 0.75, 31.50 ± 0.87 and 9.31 ± 0.48 hrs, respectively.
Budget Deficit and Fiscal Administration in Selected Sub-Saharan African Countries

Purpose of the article: An examination of budget performance’ relationship with fiscal administration in selected countries of sub-saharan Africa is the thrust of this study. Secondary data from 12 countries in Sub-Saharan Africa (SSA) for the period (2002–2016) was sought and analysed. Methodology/methods: Analytical tools deployed for statistical analysis include the Ordinary Least Square (OLS) regression method, correlation analysis, variance inflation factor (VIF) tests for multicollinearity, and Breusch-Pagan/Cook Weisberg test for heteroskedasticity. 5% level of test of significance was employed to measure the altitude of statistical association between all variables. Scientific aim: Efforts were made to empirically ascertain by means of available statistics the relationship between budget deficits and fiscal administration in SSA. Findings: Indications from this study implied that countries SSA recorded trends of significant levels of revenue decline and fiscal balances have deteriorated despite the various acclaimed adjustments in the expenditures profiles by governments in the region. Also a significant relationship was found between budget deficit and fiscal administration among countries in SSA. Conclusions: Since budget deficit has remained a recurring decimal in SSA, countries in the region have resorted to high reliance on borrowed funds to finance the increasing amounts of budget deficits; the consequence being the exposure of countries in SSA to high cost of borrowing.
The convergence of regional house prices in China

This aim of this study was to determine the extent of any convergence in house prices across China, using a regional panel data set. The results showed little evidence of convergence across the regions, although there is evidence of a ripple effect starting in Shanghai, Guangzhou and Beijing, although only the former two regions are affected by the distance from them to the respective cities.
Analysis of the resonant LCL circuit operation: the case of discontinuous current

The article is focused on the analysis of the LCL resonant circuit, which operates under discontinuous input current condition. This condition leads to the LCL topology variability phenomenon what drastically changes Inverter-LCL system properties. The LCL topology variability phenomenon is precisely described. The analytical analysis presents formulae that express VSI-LCL converter features. The theoretical results are compared with laboratory tests. The concept of Controlled Variable Frequency Resonant Converter is presented and illustrated by simulation tests. The principle of CVFRC operation is based on the LCL topology variability phenomenon.
Automatic Metadata Extraction The High Energy Physics Use Case

Master of Computer Science Automatic Metadata Extraction The High Energy Physics Use Case by Joseph Boyd Automatic metadata extraction (AME) of scientific papers has been described as one of the hardest problems in document engineering. Heterogeneous content, varying style, and unpredictable placement of article components render the problem inherently indeterministic. Conditional random fields (CRF), a machine learning technique, can be used to classify document metadata amidst this uncertainty, annotating document contents with semantic labels. High energy physics (HEP) papers, such as those written at CERN, have unique content and structural characteristics, with scientific collaborations of thousands of authors altering article layouts dramatically. The distinctive qualities of these papers necessitate the creation of specialised datasets and model features. In this work we build an unprecedented training set of HEP papers and propose and evaluate a set of innovative features for CRF models. We build upon state-of-the-art AME software, GROBID, a tool coordinating a hierarchy of CRF models in a full document cascade. Through our extensions and our own robust experimentation pipeline, we cross-validate 66 experiment variations to find new improvements in feature engineering. We succeed in enhancing the two most crucial CRF models within the cascade, reducing error by up to 25% for key classifications. Acknowledgements I would firstly like to thank my two supervisors, Dr. Gilles Louppe at CERN and Dr. Martin Rajman at EPFL, for their advice and guidance. I would also like to thank my colleagues and friends at CERN for their inspiration and support. A further thanks to Gilles for proofreading this thesis.
Voltage Collapse Risk Associated to Under-Voltage Capacitive Compensation in Electric Power System Operation

Problem statement: In the operation of an Electric Power System (EPS), it has been usual to provide reactive power injection to avoid an under-voltage bus condition. In some situations an adequate voltage profile will not be a guarantee against Voltage Collapses (VCs) that may cause blackouts as seen in many occurrences around the world. The repeatedly injection of reactive power can turn a bus into a characteristic too much capacitive. Under this condition and in the presence of a considerable percentage of the constant power load type, there will be a high risk of a VC. Any of the indices proposed in the literature as VC Proximity Indicators (VCPIs) may alert the operator about the risk. Approach: In order to elucidate the problem stated, simulations were performed using MatLab/SimPowerSystems. It was used a basic example system composed by an infinite-bus feeding, through a large impedance line, a bus load whose power could be increased in ramp manner. It is also included a shunt capacitive compensation at the load bus every time the voltage value reaches 0.9 pu. Therefore, the VC risk increase could be shown by means of graphic results and the indications of some VCPIs sensitivity indices (including the new proposed index). Results: The graphics obtained in this study is a contribution to illustrate the voltage collapse risk problem when dealing with adjustments of voltage profile to meet the system requirements. Also, a VCPI sensitivity indicator using apparent load power was tested. The results have shown that all VCPI responses are very similar for a given case and electric system. Conclusion/Recommendations: Any VCPI information can help in the decision stage between either more reactive power injection or load shedding. A routine can also be developed for a supervisory program in order to alert the operator about VC risks.

Growth models fitted to Dipturus chilensis length-at-age-data support a two phase growth

La edad y el crecimiento de la raya picuda fue estimado a partir de las bandas en los cuerpos vertebrales de 689 individuos obtenidos de las capturas incidentales de la pesqueria de merluza argentina (Merluccius hubbsi). Graficos de sesgos y el analisis de precision indicaron que el metodo utilizado para la determinacion de la edad es preciso y no sesgado (% CV = 3 % PA = 82.09 %). El analisis del tipo de borde e incremento marginal vertebral confirmo la hipotesis del deposito anual de un par de bandas. Se ajustaron tres modelos de crecimiento a los datos de largo a la edad y el modelo de dos fases produjo el mejor ajuste. Esta caracteristica nunca antes fue descripta para Dipturus chilensis y podria relacionarse con un cambio en la cuota de energia y el paso de la fase juvenil a la adulta. Las estimaciones obtenidas con el modelo de Von Bertalanffy resultaron biologicamente irrealistas, lo que demuestra la importancia de ajustar modelos alternativos a los datos. Se observo que las hembras alcanzan tallas (L∝ y DW∝) mas grandes (L∝ = 138.2 cm; DW∝ = 92.46 cm) y tienen tasas de crecimientos mas bajas (k = 0.08 yr-1) que los machos (L∝ = 106.7 cm; DW∝ = 74.52 cm; k = 0.121 yr-1). Este estudio provee informacion basica de edad y crecimiento de la raya picuda, Dipturus chilensis, en el Atlantico sur de su rango distribucion, la cual no estaba anteriormente disponible.
Molecular Elements Involved in Locust Olfaction: Gene Families in the Desert Locust Schistocerca gregaria

Pheromone-responsive neurons of insects not only require specific receptors but in addition several auxiliary components, including the “sensory neuron membrane protein,” SNMP. Accordingly, SNMP is considered as a marker for neurons responding to pheromones. For the desert locust Schistocerca gregaria, it is known that the behavior, including aggregation behavior and courtship inhibition, is largely controlled by pheromones. However, little is known about pheromones, their receptors, and the pheromone-responsive cells in locusts. In this study, we have identified two SNMP subtypes, SNMP1 and SNMP2, and compared their phylogenetic relationship and primary structure motifs with SNMPs from other species. Both SNMPs were found in chemosensory tissues, especially the antennae. Employing double in situ hybridization, we identified and localized the SNMP-expressing cells in the antennae. Cells expressing SNMP1 were localized to sensilla trichodea but also to sensilla basiconica, which in locust respond to pheromones. One or a few cells express SNMP1 within the multineuron clusters from sensilla basiconica, whereas the SNMP2 subtype was expressed in cells surrounding the neuron clusters, possibly supporting cells. Based on the finding that SNMP1 is expressed in distinct neurons under chemosensory sensilla, it is conceivable that these cells may represent pheromone-responsive neurons of the desert locust.
Lagrangian advection scheme with shape matrix (LASM) v0.2: interparcel mixing, physics–dynamics coupling and 3-D extension

Abstract. The interparcel mixing algorithm in the Lagrangian advection scheme with shape matrix (LASM) is updated to make the scheme more robust. The linear degeneration criterion is replaced by the maximum deviation of the skeleton points so that the new algorithm is more effective in controlling the shape of parcels, which is vital for long time simulation. LASM is inherently shape-preserving without any complicated filter or limiter, and it is linear. This fact contributes to the ability to preserve the sum of multiple tracers exactly on the parcels in LASM. A newly proposed terminator "toy"-chemistry test is used to test LASM, which shows that LASM can preserve the weighted sum of two reactive species precisely. The physics–dynamics coupling (i.e., tendency evaluation type) is also discussed. A flow generated by a WRF large-eddy simulation is also used to test the 3-D extension of LASM.
Digital workers by design? An example from the on-demand economy. CEPS Working Document No. 414/October 2015Monday, 19 October 2015

Recent organisational and technological changes a la Uber have generated a new labour market fringe: a digital class of workers and contractors. In this paper we study the case of CoContest, a crowdsourcing platform for interior design. Our objective is to investigate how profitable this type of work can be, also from a cross-country perspective, and why professionals choose to supply work on such a platform. Given the low returns, one might expect to see a pattern of northern employer/southern contractor. Yet analysis reveals a more nuanced pattern, in which designers supply their work even if they live in Italy, which is a high-income country. For these designers work on CoContest can make sense if they are new to the labour market and face high entry barriers, although crowdsourcing does not offer them profitable employment full time. The case of Serbia, the second-largest supplier of designers, is different, however. As a result of differences in purchasing power, if the market grows experienced Serbian designers can expect to make a living from crowdsourced contracts.
