Multiperiodic magnetic structures in Hubbard superlattices

We consider fermions in one-dimensional superlattices ~SL’s ! , modeled by site-dependent Hubbard-U couplings arranged in a repeated pattern of repulsive ~i.e., U.0) and free ( U50) sites. Density matrix renormalization group diagonalization of finite systems is used to calculate the local moment and the magnetic structure factor in the ground state. We have found four regimes for magnetic behavior: uniform local moments forming a spin-density wave ~SDW! , ‘‘floppy’’ local moments with short-ranged correlations, local moments on repulsive sites forming long-period SDW’s superimposed with short-ranged correlations, and local moments on repulsive sites solely with long-period SDW’s; the boundaries between these regimes depend on the range of electronic densities r and on the SL aspect ratio. Above a critical electronic density, r"# , the SDW period oscillates both with r and with the spacer thickness. The former oscillation allows one to reproduce all SDW wave vectors within a small range of electronic densities, unlike the homogeneous system. The latter oscillation is related to the exchange oscillation observed in magnetic multilayers. A crossover between regimes of ‘‘thin’’ to ‘‘thick’’ layers has also been observed.
Biochemical composition of zooplankton from Visakhapatnam harbour waters, east coast of India

Proximate composition, zooplankton biomass, protein, lipid, carbohydrate, organic carbon and calorific content of mixed zooplankton in the Visakhapatnam harbour waters were estimated. Biomass varied from 15.2 to 74.0 ml.100 m -3 (X =31.05 ±17.7) in the outer harbour and 10 to 64.0 ml.100 m -3 ( X =26.30±14.8) in the inner harbour. Copepods, tintin-nids, decapods and chaetognaths formed dominant groups of total zooplankton ( > 90%) in the harbour waters throughout the year. Of the biochemical fractions of zooplankton, protein formed the major component, varied from 233.6 to 563 mg.g -1 (X=379.62±107), lipid varied from 61.2 to 181 mg.g -1 (X =103±32.7). Carbohydrate ranged from 65.5 to 127.4 mg.g -1 (X =85.78±16.92), organic carbon varied from 334.9 to 461.2 mg.g -1 (X=380.44±33.6) and calorific values varied from 2.2 to 5.4 (X =3.5±.94) k.cal. g -1 . Higher values of these constituents were observed during high saline premonsoon and postmonsoon periods when the population densities of copepods, tintinnids, decapods, chaetognaths were high. Significant positive correlations (P < 0.01) observed between calorific values, protein, lipid indicates to certain extent, that latter act as metabolic reserve of the zooplankton. Based on the results zooplankton do not have extensive lipid storage suggesting that protein in addition to the lipid may serve as metabolic reserve. Relatively higher calorific values were attributed to the dominance of copepods in the zooplankton population throughout the year.
Three-point vertex functions in Yang-Mills Theory and QCD in Landau gauge

Solutions for the three-gluon and quark-gluon vertices from Dyson-Schwinger equations and the three-particle irreducible formalism are discussed. Dynamical quarks (“unquenching”) change the three-gluon vertex via the quark-triangle diagrams which themselves include fully dressed quark-gluon vertex functions. On the other hand, the quark-swordfish diagram is, at least with the model used for the two-quark-two-gluon vertex employed here, of minor importance. For the leading tensor structure of the threegluon vertex the “unquenching” effect can be summarized for the nonperturbative part as a shift of the related dressing function towards the infrared.
Does Finance Matter for Growth in the Small, Open Pacific Island Countries?

A body of evidence accumulated over the past several years, via different methods and estimation techniques, using firm–and household–level data, across many regions and countries show that finance matters for growth. Yet the role of finance in fostering growth in the Pacific, ironically, a region in dire need of sustainable growth and development, continues to appear less important, possibly for the reason that the relationship in the case of the region is not properly understood, due in turn to perhaps a lack of systematic empirical evidence. This study provides a first cross–country insight into the finance–growth nexus in the Pacific. Results, using balanced panel data extending 25 years, and the dynamic Generalised Method of Moments (GMM) estimation technique, show that finance is likely to matter for growth in the small, open Pacific Island Countries as well. Our findings strengthen the growing finance–growth literature, further alleviate scepticisms that may arise from shortcomings of different methods and estimation techniques, and have important policy implications for the Pacific.
The effects of acth, isoproterenol and Dexamethasone on the rat adrenal gland response to ethane dimethanesulphonate (Eds): A stereological study

Ethane dimethanesulphonate (EDS), an alkylating agent, caused marked atrophy of the adrenal cortex of adult male rats, in addition to its toxic effect on testicular Leydig cells. The aim of this work was to examine whether a 9-day treatment with ACTH (40 IU/kg/d), isoproterenol (120 mg/kg/d) or dexamethasone (0.25 mg/kg/d), which started 4 days prior to intraperitoneal administration of a single dose of EDS (75 mg/kg), affected the morphological changes in the adrenal cortex evoked by EDS alone. The animals were killed 15 days after EDS injection. Stereological analysis revealed that both ACTH and isoproterenol almost completely prevented cortical atrophy induced by EDS. They also considerably stimulated corticosterone secretion in EDS-injected animals. By contrast, in dexamethasone-suppressed rats, the deleterious effect of EDS on adrenocortical cells was augmented. The volume and cellularity of all cortical zones were reduced, but the remaining cells of the zona reticularis displayed considerable hypertrophy which was probably responsible for the maintenance of corticosterone secretion. These results clearly demonstrate that both ACTH and b adrenoceptor stimulation have protective action against the toxic effects of EDS on rat adrenal cortex, whereas dexamethasone exerts an opposite influence.
A Unified Model of Clustering and Classification to Improve Students’ Employability Prediction

— Data Mining is gaining immense popularity in the field of education due to its predictive capabilities. But, most of the prior effort in this area is only directed towards prediction of performance in academic results only. Nowadays, education has become employment oriented. Very little attempt is made to predict students’ employability. Precise prediction of students’ performance in campus placements at an early stage can identify students, who are at the risk of unemployment and proactive actions can be taken to improve their performance.
PAPER SERIES THE CASE FOR INTERVENING IN BANKERS ’ PAY

This paper studies banker remuneration in a competitive market for banker talent. I model, and then calibrate, the default risk of the banks generated by investments and remuneration pressures. Competing banks prefer to pay their banking staff in bonuses and not in wages as risk sharing on the remuneration bill is valuable. But competition for bankers generates a negative externality driving up rival banks’ default risk. Optimal financial regulation involves an appropriately structured limit on the proportion of the balance sheet used for bonuses. However stringent bonus caps are value destroying, default risk enhancing and cannot be optimal for regulators who control only a small number of banks. The paper allows an assessment of the intellectual arguments behind widespread calls to regulate the pay of bankers. The paper uses US data to calibrate the analysis and demonstrate the significant contribution of remuneration to default risk.

Annual variation in the foraging behaviour of thick-billed murres in relation to upper-ocean thermal structure around St. George Island, Bering Sea

We studied the foraging behaviour of adult thick-billed murres Uria lomvia as they reared their chicks at St. George Island, Alaska, USA, relative to the thermal structure of the nearby ocean water column in the summers 2004, 2006, and 2007 using data recorders attached to the birds. The thermal structure of the upper ocean varied substantially among the years. Satellite-derived sea surface temperature (SST) and water temperature at depths >40 m were higher in 2004 than in 2006 and 2007 (9.1, 8.3 and 7.8°C for mean SST; 5.1, 4.4, and 2.2°C for median bottom temperature, respec- tively). We recorded a strong thermocline in 2004 and 2007, but not in 2006. Nonetheless, the thermo- cline was one of the important foraging habitats in all years. The foraging behaviour of thick-billed murres appeared to vary with annual variation in the intensity of the thermocline and water temper- ature at depth and evidently with associated vertical distribution of prey. Birds spent more time forag- ing in stratified waters and dived to around thermocline depth (and deeper in 2007) in 2004 and 2007. However, the birds used both stratified and mixed waters in 2006 and were less likely to dive to ther- mocline depth. Main prey items delivered to chicks varied among years. Sandlance (53% of observed items) and pollock (23%) predominated in 2004, compared with cephalopods (23%), flatfishes (17%) and pollock (15%) in 2006, and cephalopods (62%), pollock (16%) and sculpins (9%) in 2007.
Distance- and spin-resolved spectroscopy of iridium atoms on an iron bilayer

The induced spin polarization of Ir atoms on a ferromagnetic Fe double layer on W(110) has been investigated with spin-polarized scanning tunneling microscopy. An unoccupied state is observed with a spin polarization exceeding $60\phantom{\rule{0.16em}{0ex}}%$ that is inverted with respect to the Fe layer. This inversion is due to the tunneling gap acting as an orbital and spin filter. Distance dependent measurements show that the spin polarization remains approximately constant over the entire experimentally accessible range, from far in the tunneling regime to 1 \AA{} from the point of contact formation. This is corroborated by density functional theory calculations which show that the inversion of spin polarization occurs within 0.5 \AA{} of the adatom.
Nearshore habitats as nursery grounds for recreationally important fishes, St. Croix, U.S. Virgin Islands

Three protected backreef embayments on St. Croix’s southeast coast were sampled to determine fish species composition and juvenile fish abundance. The three study sites (Turner Hole Bay, Robin Bay, and Great Pond Bay) were sampled monthly from July 2000 to September 2001. Juvenile reef fish assemblages were sampled using three complementary methods: visual strip transect census, fish trap, and beach seine net. By comparing juvenile fish communities from distinct habitats (patch reef, seagrass, rubble, algal plains, and sand) within the three embayments, significant differences in fish densities and number of species per area were identified. Patch reef and rubble habitats had more fish species per area than any other habitat. Juvenile fish commonly observed in embayments included scarids, labrids and haemulids. The slippery dick, Halichoeres bivittatus, the bucktooth parrotfish, Sparisoma radians, the spotted goatfish, Pseudupeneus maculatus, and newly settled Haemulon unknown were among the most abundant species found in embayments. The juvenile phase of certain economically important reef fishes appear to prefer these backreef embayments.
TEMPORAL AND SPATIAL PATTERN OF GENETIC DIFFERENTIATION IN ISOPHYA KRAUSSI

Allozyme polymorphism was studied in four samples of Isophya kraussi (BRUNNER VON WATTENWYL, 1878), a brachipterous, sedentary tettigonoid species. Three samples were collected in the Aggtelek Karst region (Haragistya 1998, Mogyoróskuti meadows 1999 and 2001) and one in the Zemplén Mts (Gyertyánkúti meadows 1998–1999). Enzyme polymorphism was investigated by polyacrylamide gel electrophoresis. All 10 scorable loci (Aldox, Est, Got, aGpdh, Hk, Idh, Mdh, Me, Pgi and Pgm) had alternative alleles in at least one sample. We detected a high level of polymorphism. On average, more than 60% of the investigated loci were polymorphic and the average number of alleles was about 2.1. The average heterozygote frequency was also high approximately 0.19. Large FIT values indicated a considerable level of genetic variation as well. The larger part of the total variation was explained by the within sample component and a relatively smaller portion of it was attributable to the between sample component. Many of the FIS values were positive indicating some heterozygote deficiency. In the analysis of spatial variation, we obtained highly significant FST values, which suggested strong genetic differentiation between the local populations. In contrast, the FST value calculated in the temporal analysis of variation was not significant. The average value of Nei’s genetic distances between pairs of samples of geographically distinct populations was 0.071 while, that estimated within the Mogyoróskút population was 0.027. Thus, the results of all analyses indicated a higher level of differentiation among the geographically distinct populations than between the two samples collected in a single population in different years. The results of the PCA analyses fully confirmed those obtained in other analyses.
Hydrogen molecular ions for improved determination of fundamental constants

An experimental scheme is proposed to help resolve the proton- (deuteron-) radius puzzle with rovibrational two-photon spectroscopy of hydrogen molecular ions measured at high precision. The technique is also expected to measure other fundamental constants, such as the Rydberg constant and the electron-proton mass ratio, at a competitive level of precision compared to the existing schemes.
The shortest-period Wolf-Rayet binary in the Small Magellanic Cloud: Part of a high-order multiple system

Context. SMC AB 6 is the shortest-period (P = 6.5 d) Wolf-Rayet (WR) binary in the Small Magellanic Cloud. This binary is therefore a key system in the study of binary interaction and formation of WR stars at low metallicity. The WR component in AB 6 was previously found to be very luminous (log L = 6.3 [L⊙]) compared to its reported orbital mass (≈8 M⊙), placing it significantly above the Eddington limit. Aims. Through spectroscopy and orbital analysis of newly acquired optical data taken with the Ultraviolet and Visual Echelle Spectrograph (UVES), we aim to understand the peculiar results reported for this system and explore its evolutionary history. Methods. We measured radial velocities via cross-correlation and performed a spectral analysis using the Potsdam Wolf-Rayet model atmosphere code. The evolution of the system was analyzed using the Binary Population and Spectral Synthesis evolution code. Results. AB 6 contains at least four stars. The 6.5 d period WR binary comprises the WR primary (WN3:h, star A) and a rather rapidly rotating (veq = 265 km s−1) early O-type companion (O5.5 V, star B). Static N III and N IV emission lines and absorption signatures in He lines suggest the presence of an early-type emission line star (O5.5 I(f), star C). Finally, narrow absorption lines portraying a long-term radial velocity variation show the existence of a fourth star (O7.5 V, star D). Star D appears to form a second 140 d period binary together with a fifth stellar member, which is a B-type dwarf or a black hole. It is not clear that these additional components are bound to the WR binary. We derive a mass ratio of MO∕MWR = 2.2 ± 0.1. The WR star is found to be less luminous than previously thought (log L = 5.9 [L⊙]) and, adopting MO = 41 M⊙ for star B, more massive (MWR = 18 M⊙). Correspondingly, the WR star does not exceed the Eddington limit. We derive the initial masses of Mi,WR = 60 M⊙ and Mi,O = 40 M⊙ and an age of 3.9 Myr for the system. The WR binary likely experienced nonconservative mass transfer in the past supported by the relatively rapid rotation of star B. Conclusions. Our study shows that AB 6 is a multiple – probably quintuple – system. This finding resolves the previously reported puzzle of the WR primary exceeding the Eddington limit and suggests that the WR star exchanged mass with its companion in the past.

Fakultät für Informatik CSR-1101 Closing feature regions

Many applications for 3d object analysis and visualization need to deal with object features. The most common features on triangulated surfaces are ridges and valleys which are interesting for matching, segmentation, smoothing, non-photo-realistic rendering and many other tasks. In some cases these features are interrupted or corrupted otherwise. In this paper we present an approach to close such gaps in feature regions. For this purpose a vector field on the surface, based on the detected features, is computed. The analysis of this vector field yields to possible junction points. These junction points are connected (guided by the vector field) to close the interrupted feature regions.
Regional Estimation of Solar Radiation using Routinal Meteorological Variables

In this paper, the monthly surface data of solar radiation, minimum and maximum temperatures, wind speed and evaporation of 1970-1995 for four climatic regions in Nigeria were obtained from the archives of Nigerian Meteorological Agency (NIMET), Oshodi, Lagos. The distributions of solar radiation with each of the four meteorological variables were observed. It was found that solar radiation was well monitored by each of the variables indicating that the linear combination of the variables can be used to develop model from where solar radiation data can be evaluated. Consequently, the multivariate linear regression model was developed using 1970-1990 data of the five meteorological parameters for each of the four regions taking solar radiation as dependent variables and the four other meteorological variables as independent variables. The models were validated using 1991-1995 data of minimum and maximum temperatures, wind speed and evaporation to obtain the predicted solar radiation. Analyses have shown that over seventy percent correlations exist between the measured and estimated values of solar radiation. The efficiency of the developed models was further verified by calculating the values of R 2 , MBE, RMSE and t-test at confidence level of p < 0 . 05. The results obtained showed that the models were statistically significant and could be used to estimate solar radiation at the regions in Nigeria. Keywords : Distribution, Meteorological, Multivariate, Radiation and Statistically.
Evaluation of MR Images of the Ankle and Foot in Response to Long-Distance Running: A Systematic Review

Background: It has remained controversial on whether excessive loadings imposed on the ankle and foot complex during long-distance running have a deleterious effect. The aim of this systematic review is to determine whether long-distance running causes any visible changes of the ankle and foot on magnetic resonance imaging (MRI). Methods: Scopus, Web of Science, Embase and Ovid Medline were searched using key terms in relation to MRI findings of the ankle and foot in response to long-distance running, published between 1990 and 2016. The final search was conducted on 19 September, 2016. Studies were identified using inclusion and exclusion criteria. Methodological quality was assessed using a modified Quality Index. Results: The database search initially produced 551 articles and it was screened based on inclusion and exclusion criteria, finally resulting in four articles. Edema was reported in the talus, tibia, calcaneus, navicular, cuboid and cuneiforms. A significant alteration in signal intensity and/or edema was appeared in the calcaneus at the Achilles insertion point, intraosseous and subcutaneous over long-distance running. The diameter of Achilles tendon was also significantly increased. However, when comparing between race finishers and non-finishers, the plantar aponeurosis and subcutaneous were only significantly different, reporting a high rate of edema in non-finishers. Additionally, one study adopted T2* mapping and found significant alteration in T2* values in tibiotalar cartilage, but the value was unexpectedly decreased in the middle of long-distance running. Conclusion: This is the first systematic review to determine the effect of long-distance running on the ankle and foot using MRI. It shows that long-distance running may cause subtle pathological and biochemical changes in the ankle and foot, including the talus, tibia, the distal and proximal group of tarsal bones, 5th metatarsals, soft tissues and the Achilles tendons. However, there is no evidence that these changes have clinical relevance.
Strategic treatment with immunomodulators to resolveendometritis in cow: A review

Postpartum uterine infections result from uterine contamination with bacteria during parturition. The uterine infection implies adherence of pathogenic organisms to the mucosa, colonization or penetration of the epithelium, and release of bacterial toxins that lead to establishment of uterine diseases. Treatment of endometritis with parenteral or intra-uterine infusion of the antibacterial agents and antibiotics have met with varying degree of success but inconsistence of recovery rate, high cost of treatment, milk disposal after antibiotic therapy, immergence of microbial resistance are obvious disadvantage of their use. They also markedly destroy the phagocytic activity of polymorphonuclear leucocytes, which are responsible for maintaining non-specific uterine defence. So, there is urgent need to find out an alternative therapy for treatment of uterine infections by activation of natural defence mechanism in the uterus. Prospects in use of certain non-specific immunomodulators in routine therapeutic protocol for endometritis and other uterine disorders is reviewed in present studies.
