The eXtensible Markup Language (XML) and XML-Schema are increasingly becoming the fa-vorite languages to exchange and describe data across the internet, respectively. In this perspective, much of database research focus is shifting from the traditional database models to semistructured data and XML. In this paper, a formal framework supporting the design of XML-Schema type hierarchies has been proposed, by following and revisiting the database approach. In particular, the notion of a legal XML-Schema type hierarchy has been formally given and an algorithm for checking the legality of type hierarchies has been proposed.
Title : Microscopic Evidence for Liquid-Liquid Separation in Supersaturated CaCO 3 Solutions

Recent experimental observations of the onset of CaCO3 mineralization suggest the emergence of a population of clusters that are stable rather than unstable as predicted by classical nucleation theory. This study employs molecular dynamics simulations to probe the structure, dynamics, and energetics of hydrated CaCO3 clusters, and lattice gas simulations to explore the behavior of cluster populations prior to nucleation. Our results predict formation of a dense liquid phase through liquid-liquid separation within the concentration range where clusters are observed. Coalescence and solidification of nanoscale droplets results in formation of a solid phase whose structure is consistent with amorphous CaCO3. The presence of a liquid-liquid binodal enables a diverse set of experimental observations to be reconciled within the context of established phase separation mechanisms.

Development and evaluation of nutritionally enhanced potato rice papads (Indian cookie)

The present study was carried out to develop papads (Indian cookie) from potato (Solanum tuberosum L.) and rice (Oryza sativa) blends and to analyze them for organoleptic, physicochemical, phytochemical and shelf life quality. Two processing cultivars (Kufri Chipsona-1, Kufri Chandramukhi) and one commonly grown cultivar (Kufri Pukhraj) were evaluated for processing into papad. Based on preliminary sensory trails, papads with boiled potato mash (60%) and gelatinized rice (30%) level of supplementation were found to be most acceptable and these papads were subjected to nutritional evaluation. Results were compared with rice papads (control). Protein content and yield was significantly (p<0.05) higher in control papads compared to potato supplemented papads. Oil uptake significantly (p<0.05) increased on supplementation with potato. Bioactive compounds including ascorbic acid, totalphenolics and total antioxidant activity measured as DPPH radical scavenging activity increased significantly (p<0.05) on incorporation of potato. Between the cultivars, papads enriched with Kufri Pukhraj, a table variety which is considered unfit for processing, displayed the highest phytochemical content and total antioxidant activity. Sensory evaluation indicated higher overall acceptability scores of potato enriched papads compared to control. During storage of papads at room temperature for up to 3 months, significant (p<0.05) changes in the moisture content, phytochemical content and antioxidant activity were observed. Storage studies showed that the potato supplemented papads can be stored safely for 3 months of storage at ambient temperature.
Investible benchmarks hedge fund liquidity

A lack of commonly accepted benchmarks for hedge fund performance has permitted hedge fund managers to attribute to skill returns that may actually accrue from market risk factors and illiquidity. Recent innovations in hedge fund replication permits us to estimate the extent of this misattribution. Using an option-based model, we fnd evidence that hedge fund returns actually refect the value of liquidity options that investors grant managers at below market values. Coupled with the competition from hedge fund replication vehicles, this analysis may motivate hedge fund managers to relax their redemption terms.

Phase Retrieval Methods for Electromagnetic Source Modeling

Modeling of the field distributions from electromagnetic sources is of interest for various applications including electromagnetic compatibility investigations, near-field to far-field transformations, antenna diagnostics and electromagnetic dosimetry. In order to determine whether exposure safety guidelines, such as the EU directive 2004/40/EC, are complied with, source modeling methods are important. Two methods for determining the total field, including phase information, when only field amplitudes have been measured on a set of planes in front of an electromagnetic source have been developed. The first method, the adjoint field method, is a gradient based optimization algorithm based on the adjoint fields. The second method, the phase angle gradient method, employs an optimization algorithm based on the phase angle gradients of a functional. The two methods have been tested for numerical test cases with both high and low frequencies and the phase angle gradient method was found to perform best. Moreover, it gave results that are in excellent agreement with the correct phase. The phase angle gradient method was also tested for measured magnetic flux density with low frequency from a transformer and for electric field with high frequency from a mobile phone. For the cases with measured field the obtained phase angles on the measurement plane closest to the source gave calculated field on other measurement planes that agrees well with measured field.
On L1 Interference and Reverse Transfer: Special Reference to the Concept of Multicompetence

As well as the first language influences the second, the second language influences the first. Therefore, researchers have to focus not only on the L1’ L2, but also on the L2’ L1 effect. There has been extensive research into how L1 affects L2, commonly known as negative influence, but a lot less about the opposite direction, commonly known as Reverse or Backward transfer.The present study attempts to examine and critically review pertinent research into the question of bidirectional influence between languages. First, it traces the conceptual framework of the notion L1†’L2 effect. Second, it attempts to demonstrate how an emerging new language (L2) affects the existing L1. Although there are several ways of conceptualizing L2 influence on L1, the focus, in the present study, is on the concept of Multi-Competence proposed by Cook (1991; 1999; 2006; 2007; 2011) and how it shifts the evaluation angle of the interlanguage system. Third, it examines the pedagogical aspects of both directions, as manifested in L2 classroom. Special focus will be given to how the concept of multicompetence sees the goal of L2 learning and how language teaching should reflect such a goal. In addition, the advantages and disadvantages of using learners first language in L2 classroom will be highlighted and specific methodological recommendations will be made.
Multi-Input Module-Integrated PV Inverter Applying GaN Devices

The trend in small scale roof-top PV-systems is towards module integrated electronics, such as AC-modules, featuring MPP tracking on PV-module level and increasing energy-yield under partial shading conditions. Unlike common AC-modules, this work investigates multi-input AC-modules with MPP-tracking on sub-module level, which eliminates mismatch losses among the substrings of a PV-module. Based on a review of AC-module topologies with single MPP-tracking, topologies for a multi-input AC-module with substring MPP-tracking are derived. As AC-modules must feature low part-count number due to cost and reliability specifications, the feasible multi-input topologies are severely restricted. A topology comparison identifies two viable candidates for a multi-input AC-module: first a LC-resonant cyclo-converter with a power-balancer multi-port and second a two-stage topology with three paralleled flyback DC-DC converters and a PWM fullbridge DCAC inverter. The latter is investigated in this work, as it features the advantage of low capacitive energy storage for single-phase powerdecoupling. To perform a model-based optimization of PV-inverters, magnetic models are required, which accurately model the losses over the wide load range of the European efficiency from 100% down to 5% of the nominal output power. To achieve the desired modeling accuracy advanced magnetic models are applied. A new method is proposed to model losses in foil windings exposed to an airgap field, which is not restricted to certain winding geometries. The method is shown to achieve modelling errors below 15%. The transformer parasitics are found to substantially influence DC-DC flyback operation at low output power. Flyback operation under these non-ideal conditions is analyzed, analytical formulas for the involved losses are derived and improved methods to model transformer parasitics are derived. GaN devices are applied, to allow an AC-module design with decent efficiency. High voltage devices with 600V blocking voltage are still a novelty and not available yet with the voltage and current rating of 600V/2A, typically required for AC-modules. Experimental results
NoC Self-Test

: Nowadays interconnect switch network has been used to connect cores in SoC to scale up the number of cores and to reduce the latency. These network communication platforms are called as Network on Chip (NoC) which supports scalability and reusability. NoC switch includes a complex logic structures such as memories, registers and interfaces which makes the testing of a switch more challenging and complex. Often the test time, test cost and fault coverage of NoC switch structures are very less and without testing the switch one cannot test the embedded cores. In this paper a NoC self-test architecture is proposed to test NoC switch by employing BIST based testing methodology.
OVERVIEW OF THE MASSIVE YOUNG STAR-FORMING COMPLEX STUDY IN INFRARED AND X-RAY (MYStIX) PROJECT

The Massive Young Star-Forming Complex Study in Infrared and X-ray (MYStIX) seeks to characterize 20 OB-dominated young clusters and their environs at distances d ⩽ 4 kpc using imaging detectors on the Chandra X-ray Observatory, Spitzer Space Telescope, and the United Kingdom InfraRed Telescope. The observational goals are to construct catalogs of star-forming complex stellar members with well-defined criteria and maps of nebular gas (particularly of hot X-ray-emitting plasma) and dust. A catalog of MYStIX Probable Complex Members with several hundred OB stars and 31,784 low-mass pre-main sequence stars is assembled. This sample and related data products will be used to seek new empirical constraints on theoretical models of cluster formation and dynamics, mass segregation, OB star formation, star formation triggering on the periphery of H ii regions, and the survivability of protoplanetary disks in H ii regions. This paper gives an introduction and overview of the project, covering the data analysis methodology and application to two star-forming regions: NGC 2264 and the Trifid Nebula.
A maturation model for project-based organisations - with uncertainty management as an ever-present multi-project management focus

The classical view of multi-project management does not capture its dynamic nature. Current theory falls short in its ability to explain how the management of project-based companies evolves because of their need to be agile and adaptable in a changing environment. The purpose of this paper is therefore to present a descriptive model that elucidates the maturation processes in a project-based organisation as well as to provide an enhanced understanding of multi-project management in practice. The maturation model illustrates the way the management of project-based organisations evolves between structuring administration and managing uncertainties, and emphasises the importance of active individual actions and situated management actions that have to be undertaken in order to coordinate, synchronise and communicate the required knowledge and skills. The outcomes primarily reveal that, although standardised project models are used and considerable resources are spent on effective project portfolio management, the way information and communication are dealt with is vitally important in the management of project-based organisations. This is particularly true of informal and non-codified communication.
Elastic stiffness coefficients of thenardite and their pressure and temperature dependence

Abstract The elastic stiffness coefficients, cij, of orthorhombic Na2SO4 thenardite (space group Fddd) were measäured with an ultrasonic plane wave technique at ambient temperature as a function of hydrostatic pressure in the range of 0.1–70 MPa. The variation of the cij in the range of 1–5000 MPa was studied with density functional theory (DFT) based calculations. The experimental results and the DFT calculations were used to derive a force-field model, which was then employed to compute lattice parameters and elastic stiffness tensors of thenardite and of two other Na2SO4 polymorphs as functions of the temperature based on quasi-harmonic lattice dynamics. The structural parameters of the three polymorphs measured at high temperatures are reproduced to within 1.7% by the present calculations. Phases II (space group Pbnm) and III (Cmcm) appear to have significantly higher entropies than thenardite in agreement with their metastable formation at higher temperatures.

Comparison of the level of neutral buoyancy observed from soundings and radar

Rapid vertical transport of heat, moisture, and chemical tracers from the boundary layer to the upper troposphere and lower stratosphere is accomplished primarily through moist convection (e.g. Dickerson 1987). Simulations of convective mass transport have been done (e.g. Stenchikov et al. 1996; Mullendore et al. 2005), but with limited observational networks, these results are relatively unconstrained. In order for atmospheric chemistry models to correctly simulate the upper troposphere and lower stratosphere, the level at which mass is being detrained must be correctly simulated. In addition, recent studies (e.g. Schumacher et al. 2004; Alexander et al. 2004) have shown that updraft size and extent relate closely to heating profiles and water vapor transport which play a significant role in the global momentum and radiative budgets. Earlier work illustrates that the vertical structure of hydrometeors and kinematic quantities such as horizontal divergence, vertical air motion, and vertical mass flux all supply important information to the location of latent heat release (Tao et al. 1993; Mapes and Houze 1995; Kummerow et al. 1996; Olson et al. 1999; Yang and Smith 1999). The level of neutral buoyancy (LNB) or the height at which parcel theory estimates that the updraft begins slowing down, is most simply estimated by lifting a representative parcel of air from the surface to the level at which air is no longer positively buoyant. Modeling work done by Raymond and Blyth (1986) shows that parcels aggregate at their LNB indicating detrainment is maximized at this level. The LNB is generally estimated from radiosonde data; however, using the LNB determined from environmental soundings as a proxy for the detrainment height may be unrepresentative in many convective situations. One reason for this is the high spatial and temporal variability between sounding stations which is normally unobserved except in extensive field experiments. This variability results in different parcel properties and estimated detrainment heights. Also, the LNB is likely varying in time as the storm continues to mature and dissipate. There are many situations in which convection forms and propagates across an area where environmental soundings are not available at that specific time or location and an estimation of the LNB is simply unknown. ___________________________________________
Post-editing wildlife documentary films : a new possible scenario?

Several studies have proven that, when machine translation followed by post-editing is used to translate general and specialised texts, there is an increase in the productivity, as the post-editing effort is lower than translating ex novo. Although the use of machine translation and post-editing has been investigated in Audiovisual Translation, this has never been researched in non-fictional audiovisual genres in which voice-over and off-screen dubbing are applied. Using an English wildlife documentary film as the source text, and Spanish as the target language, this study intends to research whether post-editing involves more or less effort than translating a documentary. Conclusions on the experiment described in this article, in which 12 Audiovisual Translation MA students took part, seem to indicate that post-editing involves less effort than translating
Domain-Speci c Keyphrase Extraction

Keyphrases are an important means of document summarization, clustering, and topic search. Only a small minority of documents have author-assigned keyphrases, and manually assigning keyphrases to existing documents is very laborious. Therefore it is highly desirable to automate the keyphrase extraction process. This paper shows that a simple procedure for keyphrase extraction based on the naive Bayes learning scheme performs comparably to the state of the art. It goes on to explain how this procedure's performance can be boosted by automatically tailoring the extraction process to the particular document collection at hand. Results on a large collection of technical reports in computer science show that the quality of the extracted keyphrases improves signi cantly when domain-speci c information is exploited.
The nature of the gift : Accountability and the professor-student relationship

In this paper I introduce the theory of gift giving as a possible means to reconcile the contradictions inherent in accountability measures of “faculty productivity” in the American university. In this paper I sketch the theory of gift economies to show how, given the historical ideals that characterize the faculty-student relationship, a theory of gift giving could help us better judge the labor of the faculty. I suggest that it is the relational character of teaching that frustrates accountability measures and that perhaps if viewed as a gift economy—and in particular an economy with “reproductive” ends—we could better grasp the effectiveness of these relationships. Post-print version of an article published in Educational Philosophy and Theory 39(6): 574-591. doi:10.1111/j.1469-5812.2007. 00307.x Nature of the Gift 3 As the demand for accountability in American higher education grows, countless efforts have been put forth by individual institutions and government policy boards to assess the performance of higher education, in particular the productivity of the faculty. Largely motivated by public demand for standards and accountability given tuition increases, state governments, accreditation agencies and universities have developed strategies and programs to evaluate the effect of the faculty on students both in and outside of the college classroom. In these efforts, however, the nature of the faculty-undergraduate student relationship in the university and its perceived relevance for undergraduate learning has been relatively free of scrutiny. There has been no deliberate theoretical (or empirical examination) conducted on the nature of the professor-student relationship, and more precisely, no attempt has been made to ascertain the relationship’s bearing on effective undergraduate learning despite accountability claims. Accountability efforts in both the public and private university sectors have signaled a desire to understand, assess and improve this unique relationship culturally rooted in the privileging of cognitive autonomy and authority. The professor-student relationship in the university has been molded by beliefs about the trustworthiness of the expert and his knowledge, thus assigning credibility and trustworthiness to the expert, while simultaneously and definitively informing the hierarchy that typifies the professorstudent relationship. The professor-student relationship is one in which actors enter with assumptions about credibility and authority. But what comprises those assumptions and how those assumptions manifest themselves in effective learning continues to go under-
A simple topography-driven and calibration-free runoff generation module

Abstract. Reading landscapes and developing calibration-free runoff generation models that adequately reflect land surface heterogeneities remains the focus of much hydrological research. In this study, we report a novel and simple topography-driven runoff generation parameterization – the HAND-based Storage Capacity curve (HSC), which uses a topographic index (HAND, Height Above the Nearest Drainage) to identify hydrological similarity and the extent of saturated areas in catchments. The HSC can be used as a module in any conceptual rainfall–runoff model. Further, coupling the HSC parameterization with the mass curve technique (MCT) to estimate root zone storage capacity (SuMax), we developed a calibration-free runoff generation module, HSC-MCT. The runoff generation modules of HBV and TOPMODEL were used for comparison purposes. The performance of these two modules (HSC and HSC-MCT) was first checked against the data-rich Bruntland Burn (BB) catchment in Scotland, which has a long time series of field-mapped saturation area extent. We found that HSC, HBV and TOPMODEL all perform well to reproduce the hydrograph, but the HSC module performs better in reproducing saturated area variation, in terms of correlation coefficient and spatial pattern. The HSC and HSC-MCT modules were subsequently tested for 323 MOPEX catchments in the US, with diverse climate, soil, vegetation and geological characteristics. In comparison with HBV and TOPMODEL, the HSC performs better in both calibration and validation, particularly in the catchments with gentle topography, less forest cover, and arid climate. Despite having no calibrated parameters, the HSC-MCT module performed comparably well with calibrated modules, highlighting the robustness of the HSC parameterization to describe the spatial distribution of the root zone storage capacity and the efficiency of the MCT method to estimate SuMax. This novel and calibration-free runoff generation module helps to improve the prediction in ungauged basins and has great potential to be generalized at the global scale.
