ON THE ROTATIONAL EFFECT IN NONUNIFORM MAGNETIC FLUIDS

In the paper, two problems are considered in which the volume ponderomotive forces associated with internal rotations are shown to be mainly responsible for generation of circulation flows in magnetic fluids. One problem is devoted to an analytical investigation of the motion of the magnetic fluid in a vertical long cylinder. The motion is generated by the high-frequency rotating field orthogonal to the cylinder axis. The velocity profile is determined in the approximation of a weak field. Theoretical and experimental results are compared. The second problem deals with an experimental study of the flow of a magnetic fluid subjected to the joint action of rotating and bias fields. It has been found that, with the bias field on, the flow structure qualitatively changes and the flow direction may be reversed.
GreenMed: A sustainable physical activity tracking application

Evidence suggests that physical activity brings substantial health benefits while its absence causes several health issues. As people become more aware of negative health outcomes associated with physical inactivity, the shift from sedentary lifestyles to healthier ones occurs, and physical activity tracking apps may help in this regard. While mobile applications for tracking physical activity are abundant, most of of them fail to deliver evidence-based recommendations. This is a major drawback especially when these apps are designed to guide users towards healthy lifestyles. This paper presents a prototype application that could provide evidence-based recommendations about how much physical activity adults should do to stay healthy according to the user’s current activity level. A new visualisation approach which uses animal representations for activity levels is also introduced to enhance user experience, increase motivation and create a good base for further integration of gamification principles. Early testing showed that users found the prototype very useful and expressed great interest towards the animal representations.
Trophic niche partitioning between two native and two exotic carnivores in SW Portugal

Abstract. The introduction of exotic species is one of the most pervasive consequences of the increased human mobility. The most known negative effects are the decrease or extinction of natives. The common-genet, Genetta genetta, and the Egyptian mongoose, Herpestes ichneumon, were introduced in the Iberian Peninsula in the 15th and 19th centuries, respectively. The competitive exclusion principle defines that two ecologically similar species cannot coexist. Thus, some degree of partitioning has to occur in species realized niche, which can occur at the trophic level. To test this hypothesis of partitioning we compared the diet of these two exotic species with that of two native species (stone marten, Martes foina, and red fox, Vulpes vulpes). The results show a high degree of overlap (>45%) between the diets of species similar in their feeding strategies (arboreal and ground feeding). Nonetheless, at the finer scale of prey consumed at the species level some differences are found between the native and exotic species. These results suggest that if coexistence is due to trophic niche partitioning it only occurs at the level of the consumed species. However, coexistence may also be due to a combination of different strategies (home-range size, time and space use) that structured the different realized niches of each species.
Velocity model estimation by full waveform inversion of time-lapse 4D passive seismic array data

In passive-source monitoring, an accurate velocity model is important to precisely estimate microseismic source locations, and to understand changes in reservoir properties. In this study, we employ frequency-domain full waveform inversion in order to obtain a high-resolution velocity model by exploiting full wavefields. We demonstrate the feasibility of the method for a surface geophone array by inverting for time-lapse 4D velocity changes in a realistic subsurface model. Our method successfully estimates the small velocity changes of a few percent within layers of 10s of meters, even for a single passive seismic source event. The analysis of wavepaths and gradients suggests that keys for the successful inversion are the use of full wavefields (both first and scattered arrivals), the vicinity of velocity changes to the source, and the wide-aperture surface array.
The Impact of the CIMMYT Wheat Breeding Program on Wheat Yields in Mexico's Yaqui Valley, 1990-2002: Implications for the Future of Public Wheat Breeding

CIMMYT has invested a large and significant amount of public expenditures in wheat breeding research each year for several decades. Estimates of the impact of the wheat breeding program on wheat yield increases provides information to scientists, administrators, and policy makers regarding the efficacy and the rate of return to these investments, providing important information for future funding decisions. Using CIMMYT test plot data from the Yaqui Valley in Mexico from 1990-2002, regression results indicate that the release of modern CIMMYT varieties has contributed approximately 53.77 kg/ha to yield annually. The growing conditions of the experiment fields located in the Yaqui Valley approximate 40% of the developing world's wheat growing conditions. A rough estimate of the gains attributed to CIMMYT's wheat breeding program on a global scale is 304 million (2002) USD annually during the period 1990-2002. CIMMYT's total wheat breeding cost in 2002 was approximately 6 million dollars, making the benefit cost ratio approximately 50 to 1.
The relationship between nutrients intake and preeclampsia in pregnant women

th , and 34 th -37 th weeks of gestation. Physical activity was also assessed using a standard questionnaire. Data on 48-hour dietary recalls was analyzed using Nutrition-IV software. Data was analyzed in SPSS18 using t-test and logistic re- gression analysis. RESULTS: The mean value of received saturated fatty acids in the first trimester in subjects who experienced preeclampsia later in pregnancy was higher than the rest of the pregnant women (p = 0.045). Manganese intake in the third trimester was significantly less in preeclamptic subjects compared to the others (p = 0.026). Moreover, vitamin C, vitamin E, fiber, and carbo- hydrate intakes during the third trimester were significantly less among the women with preeclampsia compared to the rest of the studied population (p = 0.034, p = 0.049, p = 0.046, and p = 0.035, respectively). Higher manganese (OR: 0.88; 95% CI: 0.76-0.90), vitamin C (OR: 0.985; 95% CI: 0.98-0.99), vitamin E (OR: 0.99; 95% CI: 0.984-0.996), fiber (OR: 0.97; 95% CI: 0.96-0.98), satu- rated fatty acids (OR: 1.028; 95% CI: 1.02-1.036), and carbohydrate (OR: 0.98; 95% CI: 0.97-0.99) intake increased the chance of preeclampsia in pregnant women. CONCLUSIONS: The amounts of received saturated fat in the first trimester and manganese, vi- tamin C, vitamin E, fiber, and carbohydrate during the third trimester are significantly associated with preeclampsia.
Actions to promote climate resilience in forests of British Columbia

Climate change has introduced major uncertainties into the planning and practice of forestry. We recommend seven broad actions that would help to make our forests more climate resilience: avoiding entrapment, emphasizing the future, adopting a policy of no regrets, seeking the right species at the right place, encouraging connectivity, nurturing acceptance and adaptation, and reducing carbon emissions. Some actions are specific to British Columbia; all actions attempt to address the major sources of uncertainty
The role of educational expansion in the early occupational attainment process: Empirical evidence from a cross-national perspective

In this paper, we investigated the role of educational expansion in the early occupational attainment process from a cross-national perspective. Beyond an eventual direct, positive effect of education (net of social origin) on early occupational attainment, we explored if education has a different payoff depending on social origin, and if such effects are associated to educational expansion. For the empirical analysis, we used four rounds of the European Social Survey (ESS) (collected in 2002, 2004, 2006 and 2008). We applied multilevel analysis on a selection of 18,251 individuals, who had left education at most ten years before the moment of interview, from 29 countries. The results first of all showed that education (net of social origin) has a strong positive effect on early occupational attainment. Moreover, the occupational returns to education vary by social origin: the returns are largest (smallest) among those of whom their father worked in a professional occupation (was an unskilled worker). Second, we found that educational expansion lowers occupational attainment in general and that the (differential) occupational returns to education are smaller when education expands (credential inflation).

Franz-Keldysh effect in an optical waveguide containing a resonant tunneling diode

We report on work concerned with the optoelectronic properties of a GaAs optical waveguide containing a resonant tunneling diode (RTD). 1 As far as we are aware this is the first report of an RTD directly incorporated in an optical waveguide and the observation of optical modulation via a Franz-Keldysh shift on the band edge. Figure 1 shows a cross-section schematic of the device. The device that was employed for our Franz-Keldysh band-shift measurements consisted of a 4-μm-wide optical waveguide with a 200-μm-long contact on top of the waveguide defining an active area of 800 μm2. Figure 2 shows the IV curve for this optical waveguide RTD. Resonance was found to occur at a bias of 0.9 V with a sharp drop in the current indicating bistability but not oscillation. Optical characterisation was carried out with the aim of determining the change in the optical absorption spectrum when the device switched. Optical characterisation of the device employed a Ti:sapphire laser that was tuneable in the wavelength region close to the band-gap resonance of the waveguide, i.e., close to 890 nm. In order to minimise thermal effects in the RTD a pulsed power supply was used. When the pulse amplitude exceeded Vb the current through the RTD would switch rapidly from Ib to Ic (see Fig. 2). An increase in absorption along the length of the RTD was observed upon switching due to the RTD. No change in absorption was observed when the device was biased below Vb.
A STUDY OF ASSOCIATION RULE MINING IN FRAGMENTED ITEM-SETS FOR PREDICTION OF TRANSACTIONS OUTCOME IN STOCK TRADING SYSTEMS

In this research we majorly focus on predicting the behavior of Indian IT stock market. As the stock market is considered to be highly fluctuating, so predicting the behavior of such stock market needs some strong mathematical methods. We propose a technique named Fragment based mining; this method basically deals in grouping the stocks of different shares and producing some kind of association among the shares of different IT companies which helps in predicting the IT stock market. We group the shares based on small and large scale companies from Indian IT stock market data e.g. Bombay Stock Exchange (BSE). And also we will try to show the correctness of our method by applying the method on the historical data and generating some promising rules in the stock data.
Miranda localization during asymmetric cell division of neuroblasts in Drosophila melanogaster

This study characterizes the complex mechanism of asymmetric protein localization in neuronal stem cells of the central nervous system of Drosophila. Confocal fluorescence microscopy and GFP fusion protein experiments in living embryos revealed that the localization of the adaptor proteins Miranda and PON is regulated differently. Miranda localization was shown to be dynamic and to rely on cytoplasmatic diffusion and active Myosin II and VI. Moreover, for the first time it was shown that Miranda is phosphorylated in vivo. Miranda “loss of function” germline clones revealed a strong phenotype manifested in abnormal cell and spindle morphology, indicating that Miranda is essential during embryogenesis.
Predicting Nest Success from Habitat Features in Aspen Forests of the Central Rocky Mountains

—We collected nesting data on bird use of aspen stands in the Routt and Medicine Bow National Forests between 1987 and 1989. We found active nest sites of 28 species of small nongame birds on nine study plots in undisturbed aspen forests. We compared logistic regression models predicting nest success (at least one nestling) from nest-site or stand-level habitat predictors. Most common species used nest sites in aspen trees in forest interior locations (distance to edge >100 m), with dense trees (opening >100 m away) despite no apparent positive correlation with use of these habitat features and nest success rates. Further investigation may demonstrate that these forest interior sites do not experience lower predation and cowbird parasitism rates than nest sites near openings. We recommend adaptive management experimental treatments, including carefully planned cutting and controlled burns, that should benefit most birds in western aspen forests.
RECYCLING OF CARBON CONTAINING ALUMINUM MATRIX COMPOSITES VIA THEIR REMELTING

Nowadays aluminum alloys are strong enough to have good mechanical properties. What is their weak point is stiffness (Young modulus) that cannot be significantly improved be standard alloying elements. Carbon or carbon containing substances like silicon carbide with high values of Young modulus are often used in aluminum matrix composites with intention to increase stiffness of the resulting material. However, carbon bearing aluminum matrix composites are not easily recycled via melting because of reactivity of molten aluminum with carbon or carbides. Direct remelting of Al-SiC composite resulted in silicon containing melt and aluminum carbide while oxide envelop of input material keeps original shape to as high temperature as 850 °C. Addition of fluxes helps to break oxide layers but it does not prevent aluminum from reaction with carbon to form aluminum carbides.
The advantages of interdisciplinarity in modern science

As the increasing complexity of large-scale research requires the combined efforts of scientists with expertise in different fields, the advantages and costs of interdisciplinary scholarship have taken center stage in current debates on scientific production. Here we conduct a comparative assessment of the scientific success of specialized and interdisciplinary researchers in modern science. Drawing on comprehensive data sets on scientific production, we propose a two-pronged approach to interdisciplinarity. For each scientist, we distinguish between background interdisciplinarity, rooted in knowledge accumulated over time, and social interdisciplinarity, stemming from exposure to collaborators' knowledge. We find that, while abandoning specialization in favor of moderate degrees of background interdisciplinarity deteriorates performance, very interdisciplinary scientists outperform specialized ones, at all career stages. Moreover, successful scientists tend to intensify the heterogeneity of collaborators and to match the diversity of their network with the diversity of their background. Collaboration sustains performance by facilitating knowledge diffusion, acquisition and creation. Successful scientists tend to absorb a larger fraction of their collaborators' knowledge, and at a faster pace, than less successful ones. Collaboration also provides successful scientists with opportunities for the cross-fertilization of ideas and the synergistic creation of new knowledge. These results can inspire scientists to shape successful careers, research institutions to develop effective recruitment policies, and funding agencies to award grants of enhanced impact.
Environmental factors influencing the distri- bution of Arvicola scherman (Shaw, 1801) at the southwestern edge of its distribution

During 2008, damage to pastures in the eastern mountains of the province of Lugo (NW Spain) was detected, probably due to an increase in populations of Arvicola scherman (Shaw, 1801). Due to the scanty information available on this species in the area we conducted a study with the following main aims: i) to predict the current geographic distribution of the species, ii) identify the environmental variables that may determine their geographic distribution, iii) verify interannual variations in abundance and iv) develop a risk map of populations outbreaks. A total of 280 grassland fields were sampled in which species abundance was evaluated by using presence signs (earth tumuli or mounds), and subsequently an abundance index was estimated. The MAXENT programme developed a potential distribution map using the variables: potential evapotranspiration, water balance, altitude and average annual values of temperature and precipitation. The species was found only in the eastern mountains at altitudes of more than 700 m. Altitude and water balance were the variables that best predicted the presence of the species. Furthermore, a significant difference in the relative abundance between 2008 and 2010 was found, suggesting that the species may experience strong demographic fluctuations in the study area. Probably, the increase in grasslands over the last 40 years may have favoured the expansion and abundance of the species in the study area.
AN IMAGE-BASED APPROACH FOR THE ARCHITECTURAL MODELING OF PAST STATES

During the modelling process, 3D models are not easily conceived to support changes over time. On the contrary, for the description of cultural heritage, it is often necessary to display not only the actual state of buildings but also their previous states so to understand their modifications. The construction and structuring of spatio-temporal models of cultural heritage demand a double conceptual effort: on one side, 3D models must be reconstructed and structured in space according to architectural concepts; on the other one, such elements should follow the criteria of temporal decomposition. For this reason, links between structured elements should be established to keep track of changes over time. Moreover, only the current state can be reconstructed in a rigorous way using a combination of different 3D measurement techniques (such as laser scanning and photogrammetry); on the contrary, knowledge about past states is conditioned by missing elements, whose morphology and dating can reveal uncertain. For this reason, this paper describes a methodological approach to make use of the existing iconographic corpus for the analysis and the 3D management of building transformations. The aim is to establish a relation between the iconography used for the hypothetical reconstruction and the 3D representation that depends on it. As a result, 3D representations can be used like visualization systems capable of reflecting the amount of knowledge produced studying historic buildings.
A randomized trial of culturally accommodated versus standard group treatment for Latina/o adolescents with substance use disorders: Posttreatment through 12-month outcomes.

OBJECTIVES Latina/o adolescents are at particular risk for substance use disorders (SUDs) and effective treatments are needed. Some critics indicate that standard evidence-based treatments may not meet the needs of Latina/o adolescents and culturally accommodated treatments are needed; however, few comparative studies have been conducted to test this assumption. This randomized trial was designed to test a standard group-based version of a cognitive-behavioral treatment (S-CBT) against its culturally accommodated equivalent (A-CBT) for a sample of Latina/o adolescents with SUDs. METHOD Seventy Latina/o adolescents were randomly assigned to 1 of 2 treatment conditions and followed over 4 posttreatment time points with the last at 12-months. Generalized longitudinal mixed models for count data were conducted to evaluate treatment differences across time for adolescent substance use. The cultural variables ethnic identity, acculturation, and familism were included in the analysis as potential moderators of treatment outcome. RESULTS A significant difference was found at the 12-month follow-up in favor of the culturally accommodated treatment (d = .92, 95% confidence interval, CI [.43, 1.42]) and parental familism moderated treatment outcome (d = .60, 95% CI [.12, 1.08]). CONCLUSION This is one of the first studies to demonstrate that a culturally accommodated treatment differentially improved outcomes compared with that of its standard equivalent for a sample of Latina/o adolescents with SUDs.

Contribution Level Calculation to Similarity Measuring in Collaborative Filtering

Collaborative filtering is the well-known recommendation technique to make a prediction for the given user/item pair based on the rating of similar users/items. Hence, it largely relies on the similarity measure of the users/items. Pearson similarity and Cosine similarity are two of the most famous similarity measures but these measures just take into account the similarity of common ratings and thus have some defects when applying to the realistic application. In addiction to plain similarity measures, we propose a contribution level calculation to similarity measures and discuss the neighborhood selection of similar user/items to further improve the rating prediction. Experiments are evaluated over the classic datasets of recommendation problems and the result shows that the newly proposed measure on the similarity calculation is better than the original one.
Naming things

Neuropsychological assessment is undertaken in epilepsy surgery candidates for a number of reasons. One of the primary purposes is to provide information of relevance to the lateralization and localization of the seizure onset zone. Naming tasks are among the most predictive of the laterality of temporal lobe epilepsy in adults.1,2 Auditory naming in this population is more predictive than traditional visual object naming, as assessed by classic measures such as the Boston Naming Test (BNT). 3 The pediatric epilepsy literature is less clear in this regard, with multiple studies showing no association between naming performance and laterality of temporal lobe epilepsy.4 This difference has been attributed by some to developmental differences between children and adults: specifically, the burgeoning specialization and localization of language functions in children.5 The competing hypothesis is that previously used assessments of naming ability, and especially visual naming, were designed for and validated in adult populations and were developmentally inappropriate and inaccurate in pediatric populations. Hamberger and her colleagues6 have recently developed and validated age-appropriate visual and auditory naming tests for children.
