Exact results in N=8 Chern-Simons-matter theories and quantum geometry

We show that, in ABJ(M) theories with N=8 supersymmetry, the non-perturbative sector of the partition function on the three-sphere simplifies drastically. Due to this simplification, we are able to write closed form expressions for the grand potential of these theories, which determines the full large N asymptotics. Moreover, we find explicit formulae for the generating functionals of their partition functions, for all values of the rank N of the gauge group: they involve Jacobi theta functions on the spectral curve associated to the planar limit. Exact quantization conditions for the spectral problem of the Fermi gas are then obtained from the vanishing of the theta function. We also show that the partition function, as a function of N, can be extended in a natural way to an entire function on the full complex plane, and we explore some possible consequences of this fact for the quantum geometry of M-theory and for putative de Sitter extensions.
Temporal variation, growth and natural mortality of two species of mojarras (Perciformes: Gerreidae) from a tropical coastal lagoon: La Carbonera, Yucatan, Mexico

This study reports seasonal variation, growth parameters and natural mortality for Eucinostomus gula and Eucinostomus argenteus inhabiting La Carbonera, a tropical coastal lagoon on the northwestern coast of the Yucatan Peninsula, Mexico. Specimens were collected between April 2009 and March 2010. A total of 2700 organisms of E. gula (> 80% in rainy season ) and 1577 organisms of E. argenteus (>50% in dry season) were collected during the study period. Length-weight relationship (LWR) obtained was W = 8.323E-03 Lt2.92 in E. argenteus and W = 7.314E-03 Lt2.92 in E. gula. Growth parameters of von Bertalanffy growth function (VBGF) by length frequency analysis were in E. argenteus: L∞ = 13.65 cm, k = 0.54 year-1 and t0 = - 0.37 years; and in E. gula: L∞ = 12.60 cm, k = 0.68 year-1 and t0 = - 0.28 years. Additionally, estimated natural mortality in E. gula was 1.50 year-1 and in E. argenteus was 1.9 year-1. This study presents the first estimation for both species of model parameters, growth performance index and mortality for the Yucatan Peninsula, which is relevant for the proper implementation of conservation measures for E. gula and E. argenteus in an important coastal zone of the Yucatan Peninsula.
Influence of saline stress on the abundance of lime aphid (Eucallipterus tiliae L.) on the leaves of street trees - crimean linden

This publication presents the influence of soil salinity on the abundance of aphids on the leaves of street trees in cities. The objects of research were trees of Crimean Linden (Tilia ‘Euchlora’) planted at Zwirki and Wigury Street in Warsaw. The research included the evaluation of the trees’ condition, the counting of the number of Lime Aphid (Eucallipterus tiliae L.), as well as the determination of chlorine and nitrogen content in the leaves. The research revealed a statistically significant influence of chlorine content in the leaves on the deterioration of their condition. The increased content of chlorine in the leaves was accompanied by a decrease in the number of aphids. This relationship was statistically significant. No nitrogen deficiency in the leaves was detected. No statistically relevant relationship between the nitrogen content and the condition of the trees was observed. There was a weak negative correlation which, however, was statistically insignificant. Using the regression function it was determined that the increase in chlorine content in leaves by 1% (from 1.0 to 2%) resulted in a decrease in the abundance of aphids by 49%. What is more, a statistically significant (p = 0.032) influence of nitrogen content on the abundance of aphids was proved. The increase of this element by 1% (from 2.5 to 3.5%) was accompanied by the increase in the number of aphids by 90%.
Density, habitat use and behaviour of the weedy seadragon Phyllopteryx taeniolatus (Teleostei : Syngnathidae) around Sydney, New South Wales, Australia

The vulnerability of marine fish species, particularly those inhabiting coastal waters, is an increasingly important issue in marine conservation. Although the weedy seadragon Phyllopteryx taeniolatus (Lacepede, 1804), a syngnathid fish endemic to southern Australia, is legally protected in New South Wales, there are no studies on population density, habitat use and behaviour to support this protection. We investigated the abundance, sex ratios and distribution of the weedy seadragon at three sites near Sydney, Australia. The distribution, density and sex ratios of seadragons were temporally stable, suggesting no large-scale seasonal migrations. Estimated population densities varied among sites from 10 individuals per ha to 65 individuals per ha, with sex ratios close to 1 : 1. Survival rates from one encounter to the next (approximately weekly) were high, being slightly lower for males (0.985 ± 0.006, mean ± se) and females (0.987 ± 0.005) compared with juveniles (1.000 ± 0.000). All size classes and both sexes were most common near the border of kelp and sand except when exhibiting hiding behaviour, when they were more often found in kelp beds. Kelp beds were the least-used habitat when feeding. Pregnant males tended to hide more often than other groups and therefore were more frequently found in kelp and kelp patches. Seadragons tended to be solitary, although pairing and grouping behaviour was also observed. Results of the present study show that weedy seadragons are resident in the same area throughout the year and have a strong affinity with heavily weeded rock and/or sand habitat. It is therefore recommended that the current species-based protection laws be used in concert with habitat-protection zones as a necessary measure to ensure the conservation of weedy seadragon populations.
Estimation of the Main Factors Influencing Haze, Based on a Long-term Monitoring Campaign in Hangzhou, China

ABSTRACTEight years of data on haze and visibility (2003–2010) and one year of (2010) data on surface meteorological elements (relative humidity, wind speed, air temperature), visibility and the concentrations of air pollutants (PM2.5, SO2, NO2 and O3) measured each hour of each day were analyzed using correlation analysis to investigate the main factors influencing haze in Hangzhou, China. The occurrence of hazy weather has become more frequent over the past eight years in Hangzhou, and haze appears about 160 days per year. The occurrence of haze during the day was more frequent in the spring and the winter and less frequent in the summer and the autumn. Low visibility occurred in the morning, and the maximum visibility occurred in the afternoon period. The results of the statistical analysis show that the relative humidity and the concentration of PM2.5 played the most important roles in reducing visibility. The correlation coefficients between the concentration of PM2.5 and the concentrations of O3, SO2 and NO2 indicate that O3 and NO2 are the dominant factors contributing to PM2.5 pollution, which, in turn, can lead to haze. To reduce the number of haze days, greater concern and more countermeasures should be taken to decrease the O3 and NO2 pollution in Hangzhou, China.
Preparation of immunoaffinity column for rapid purification of human DNA polymerase delta and its subassemblies

Mammalian deoxyribonucleic acid (DNA) polymerase delta (pol δ) is well characterized as a tightly associated heterotetrameric complex. It is thought to play a central role in chromosomal DNA replication and various DNA repair processes. However, the availability of highly purified active pol δ becomes one of the major barriers for its in-depth functional and structural analysis. In this work, a powerful immunoaffinity column was prepared. The human DNA pol δ and its subassemblies were reconstituted with a novel MultiBac system, over-expressed in insect cells, and followed by purification using immunoaffinity chromatography in combination with ion-exchange chromatography. Starting from 500 ml of infected Sf-9 cells, as much as 5 mg of recombinant pol δ with different subunit combinations was isolated near homogeneity with active forms that were conformed by the assays both on sparsely primed poly (dA)/oligo (dT) template-primer and on singly primed M13 DNA template. Thus, our home-made immunoaffinity column provides a significant advance in the isolation of pol δ, allowing its facile isolation from over-expressed insect cells or natural source in good yield and high purity.
The management of human resources in Malaysia: Locally-owned companies and multinational companies

This paper is concerned with people management practices in companies in Malaysia. It examines the development of the main practice areas of the management of human resources (HR), the HR management (HRM) function and to what extent locally-owned companies (LOC) are influenced by multinational companies (MNC) operating in Malaysia. We found LOCs do not place a high priority on their HR practices and do not benchmark against the HR practices of MNCs. Overall, Malaysian people management generally would be better characterized as still more like 'personnel', than 'HR', management. Any acceptance and development of the HRM concept by Malaysian companies has been slow and cautious. This situation may prove problematic for future competitiveness and upgrading in the context of low wage cost competition from other countries.
Satellite Image Resolution EnhancementUsing Arsis Based Pan sharpening Methods

Resolution enhancement (RE) schemes (which are not based on wavelets) suffer from the drawback of losing high frequency contents (which results in blurring). Here we propose the Adaptive wavelet- transform-based (AWT) for resolution Enhancement in satellite images. A satellite input image is decomposed by DT-CWT (which is nearly shift invariant) to obtain high-frequency sub bands. The high-frequency sub bands and the lowresolution (LR) input image are interpolated using the Lanczos interpolator. The high frequency sub bands are passed through an NLM filter to cater for the artifacts generated by DT-CWT (despite of its nearly shift invariance). The filtered high-frequency sub bands and the LR input image are combined using inverse DT-CWT to obtain a resolution-enhanced image.We propose DWT for sub band interpolation process and we compare the resolution of satellite image enhancements using Wavelet Methods with ARSIS methods.
What Does the Bird Say? Exploring the Link Between Personality and Language Use in Dutch Tweets

The aim of this paper is to ascertain whether the use of language in Dutch tweets can offer researchers insight into the personality of the user posting those tweets. A database was created, containing the tweets of twenty Belgian, Dutch-speaking Twitter users with an equal representation of both genders. All subjects filled in a personality test based on the Big Five Model of personality and two linguistic analyses were performed on the Dutch tweets. In a first analysis, a more abstract representation of the language was created by means of Part-of-Speech tagging. For the second analysis, typical sentiment and personality-charged words were derived from the tweets based on well-known lexicons. Though our database is rather limited, we were able to find some interesting correlations between certain personality traits and language use. Keywords–Personality; Big Five; Sentiment analysis.
The relationship between emotional intelligence and complexity , accuracy and fluency in EFL learners ’ oral performance

Over the last three decades, emotional intelligence (EI) has received considerable empirical attention especially in academic context. Following this line of research, the study reported in this paper investigated the relationship between trait EI and EFL learners’ second language (L2) oral performance. A sample of 102 Iranian EFL students, all between 13 and 18 years old (approximately half male and half female), performed an oral narrative task under laboratory conditions and completed the trait emotional intelligence questionnaire-adolescent short form (TEIQue-ASF), which is used to measure global trait EI. The correlational analysis of the results indicated a positive relationship between EI and learners’ L2 oral performance as measured in terms of complexity, accuracy and fluency. Those with higher degree of EI were able to produce more accurate and complex language. The relationship between EI and fluency measures, however, did not reach significance. Findings of this study point to the importance of focusing on learners’ emotions and finding strategies to foster it.
Interactive comment on “Effects of relative humidity on aerosol light scattering in the Arctic” by P. Zieger et al

Comment: This paper summarizes 3 months of measurements of aerosol optical and physical properties at Zeppelin station in the Arctic. While Zeppelin has had long term measurements of light scattering and absorption at low RH, the unique finding reported here is the measurement of hygroscopic growth f(RH) measured by two nephelometers. Using size distribution measurements, an assumed composition and Mie code they do achieve closure on the dry scattering measurements. Based on the success of
SELECCIÓN RECÍPROCA RECURRENTE EN POBLACIONES DE MAÍZ DE VALLES ALTOS EN SUELOS CON ALTO Y BAJO CONTENIDO DE NITRÓGENO, EN MÉXICO RECIPROCAL RECURRENT SELECTION IN MEXICAN HIGLAND VALLEYS MAIZE POPULATIONS UNDER HIGH AND LOW SOIL NITROGEN CONTENT

The objective of this study was to evaluate two cycles of reciprocal recurrent selection in Highland Valley maize (Zea mays L.) populations 902 (A) and 903 (B), from the International Maize and Wheat Improvement Center of (CIMMYT) in soils with high and low nitrogen content. Using selection cycles 0, 1 and 2 of populations A and B, nine crosses Ai×Bj (i, j=cycle 1, 2, 3) were formed. The F2 generation of cycle i of the A population and cycle j of the B population, the Ai×Bj crosses, plus ACROSS96902, ACROSS96903, CMS929001, ASPROS721 and CMS939083 as controls, were evaluated in soils with high and low nitrogen at El Batan, Mexico, and in high nitrogen soils at Montecillo, Mexico, in 2000 and 2001. The experimental design was a randomized complete block with three replications. The average yield of the crosses Ai×Bj (8.24 t ha− −1 ) was not statistically different from the
The non-permanence of optimal soil carbon sequestration

Carbon sequestration in agricultural soils is considered as an option of greenhouse gas mitigation in many countries. But, the economic potential is limited by the dynamic process of saturation and the opportunity cost of land use change. In addition, this article shows that permanence cannot, in general, be achieved in the strict sense of maintaining the soil carbon stock on an increased equilibrium level. Rather, a cyclical pattern with periodical release of sequestered carbon can be economically optimal from both the farmers’ and societal point of view.
Littoral invertebrates associated with aquatic plants and bioassessment of ecological status in Lake Bracciano (Central Italy)

Lake Bracciano is a large and deep volcanic lake which plays an unquestionable role for drawing water source and for fishing and recreational activities. The existence of a project aimed at increasing the amount of water drawn from the lake suggested the advisability of undertaking an ecological analysis of the invertebrate community associated with aquatic plants in order to obtain a detailed knowledge of its composition, biodiversity and quantitative structure, and to provide a set of basic and essential information for defining the ecological status in the littoral zone and for future bioassessments in the lake ecosystem. A good water quality, approaching oligotrophy, was evidenced both from data on aquatic vegetation, which showed the extensive colonization of Charales (down to a depth of about 20 m), and from faunal parameters such as high species richness and diversity values, presence and abundance of bioindicator taxa (mainly cladocerans and gastropods), abundances of total fauna. Nevertheless, a considerable disappearance of the reed thicket due to the intense shore management for recreational purposes have negatively influenced the colonization of the more shallow and productive waters, so evidencing a negative trend of the littoral quality.
A Statistical Method for Improving Continental Shelf and Nearshore Marine Climate Predictions

AbstractSpatially and temporally homogeneous measurements of ocean temperature variability at high resolution on the continental shelf are scarce. Daily estimates of large-scale ocean properties are readily available from global ocean reanalysis products. However, the ocean models that underpin these reanalysis products tend not to have been designed for the simulation of complex coastal ocean variability. Hence, across-shelf values are often poorly represented. This study involved developing a statistical approach to more accurately and robustly represent SST on the continental shelf informed by large-scale satellite observations and reanalysis data or model output. Using the southeastern Australian shelf region as a case study, this paper demonstrates that this statistical model approach generates more accurate estimates of the inshore SST using (i) offshore SST from Bluelink Reanalysis (BRAN) and (ii) the statistical relationship between inshore and offshore SST in observations from the Advanced Very H.
Evaluation of heavy metal toxicity on radish: comparison between soil and floating hydroponics systems.

Two plant growing methods, namely use of soil and a floating hydroponic system, were compared in order to determine whether the response of radish to Cd, Cu, Ni and Zn was affected by the cultural system. Seed germination, plant biomass (root, shoot, hypocotyl), and heavy metal accumulation in different parts of the radish plants were monitored. The presence of heavy metals in the germination medium had no effect on seed germination, while the biomass of plants grown in hydroponics was negatively affected by the presence of metals in the nutrient solution. In both cultural systems, the amount of metals in roots, hypocotyls and shoots increased significantly with the increasing metal concentration in the growth media; the highest concentrations of heavy metals were found in the roots. The bioconcentration factor (BCF) and translocation factor (TF) values for the four metals were found to be considerably different between both growing systems. The different responses of plants suggest that in contaminated soils the plants are in the presence of lower quantities of available metals than those found in the corresponding substrates of the hydroponic system.
Maternal Carriage and Neonatal Colonization of Streptococcus agalactiae in Tabriz, Northwest Iran

Group B Streptococcus (GBS) is a major cause of severe systemic and local infections in newborns. This study was performed to evaluate the presence of GBS in pregnant women and their newborns in Tabriz, Iran. Vaginal specimens were collected from 965 women who were candidate for vaginal delivery for bacteriological study of group B streptococci. Several samples from various sites of the newborns' body (ear canal, nose, navel, and groin) were also obtained to study the colonization rate in newborns after vaginal delivery. Identification of GBS strains was accomplished by bacteriologic al and serological tests. During the study period, 327 microorganisms were isolated from vaginal specimens of pregnant women from which 5.2% were Streptococcus agalactiae. Serotypes of S. agalactiae strains in our study were Ia (17.6%), Ib (13.4%), II (14.2%), III (9.5%), IV (8.2%), V (19.5%) and nontypable (17.6%). All of the newborns were followed up for eight weeks. Low carriage rate of GBS in vaginal canal of women in this area and probably lack of more virulent serotypes of GBS may explain the rarity of disease due to Streptococcus agalactiae in our region.

Growth, Taxes, and Government Expenditures: Growth Hills for U.S. States

Barro-style models of endogenous growth imply that economic growth will initially rise with an increase in taxes directed toward economically "productive" expenditures (e.g., education, highways, public safety), but will subsequently decline—consistent with a "growth hill"—as the rising tax share depresses the net return to private capital. Previous tests focus on whether the linear incremental effect of taxes is positive, negative, or zero, with substantial evidence for all three conclusions. This study incorporates potentially non-monotonic effects for fiscal policy. Based on estimates for U.S. states, the incremental effect of taxes directed toward publicly provided productive inputs is initially positive, but eventually turns negative, consistent with a growth hill.
Title Fragment shapes in impact experiments ranging from crateringto catastrophic disruption

Laboratory impact experiments have found that impact fragments tend to be elongated. Their shapes, as defined by axes a, b and c, these being the maximum dimensions of the fragment in three mutually orthogonal planes (aP bP c), are distributed around mean values of the axial ratios b/a 0.7 and c/a 0.5. This corresponds to a:b:c in the simple proportion 2:p2:1. The shape distributions of some boulders on Asteroid Eros, the smalland fast-rotating asteroids (diameter <200 m and rotation period <1 h), and asteroids in young families, are similar to those of laboratory fragments created in catastrophic disruptions. Catastrophic disruption is, however, a process that is different from impact cratering. In order to systematically investigate the shapes of fragments in the range from impact cratering to catastrophic disruption, impact experiments for basalt targets 5–15 cm in size were performed. A total of 28 impact experiments were carried out by firing a spherical nylon projectile (diameter 7.14 mm) perpendicularly into the target surface at velocities of 1.60–7.13 km/s. More than 12,700 fragments with bP 4 mm generated in the impact experiments were measured. We found that the mean value of c/a in each impact decreases with decreasing impact energy per unit target mass. For instance, the mean value of c/a in an impact cratering event is nearly 0.2, which is considerably smaller than c/a in a catastrophic disruption ( 0.5). The data presented here can provide important evidence to interpret the shapes of asteroids and boulders on asteroid surfaces, and can constrain current interpretations of asteroid formation. As an example, by applying our experimental results to the boulder shapes on Asteroid Itokawa’s surface, we can infer that Itokawa’s parent body must have experienced a catastrophic disruption. 2015 The Authors.

Do Physics Textbooks Present the Ideas of Thought Experiments?: a Case in Indonesia

This study sought to check and evaluate whether or not thought experiments presented in the Indonesian physics textbooks can be used as tools to transfer scientific knowledge. This was a descriptive study using Indonesian physics textbooks as the primary sources of data. In this study, we analyzed thirty (30) physics textbooks from Grades 10 to 12 which are widely used both by teachers and students. The results showed that majority of physics textbooks did not mention about thought experiments. Only 6 physics textbooks presented thought experiments at a satisfactory level. The number of physics textbooks that described thought experiments in fair and poor levels are 9 and 5 respectively. The study concludes that Indonesian physics textbooks published from 2009 to 2017 generally lack thought experiments. Many authors of these Indonesian physics textbooks ignored or inadequately present thought experiments. Moreover, 70% of thought experiments mentioned in the physics textbooks were in the fair and poor levels. So, in general, thought experiments presented in the Indonesian physics textbooks cannot be used as an introduction in transferring scientific knowledge to science students.
