Square-Edge Graphs

An edge of a graph is called a square-edge if it lies in exactly one 4-cycle. A graph G is a square-edge graph if it contains a sequence of square-edges whose removal produces a spanning tree of G. Cube-free median graphs can be characterized as square-edge graphs which contain no Q3 as a subgraph. Among square-edge graphs, the class of partial cubes coincides with the class of semimedian graphs. A recognition algorithm for square-edge graphs of complexity O(a(G)|E(G)|) is also presented, where a(G) is the arboricity of a graph G.
Goat kid slaughter value and muscle quality after dietary supplementation with an alfalfa protein–xanthophyll concentrate

Abstract. The objective of this study was to determine the effect on goat kids of supplementation with protein–xanthophyll concentrate (PX) obtained from alfalfa (Medicago sativa). Assessments were made on carcass dressing percentage and the lipid profiles of muscle tissue. When the animals reached 30 days old (the start of the fattening period), they were allocated to two feeding groups: a control group (K), which received a standard concentrate diet, and an experimental group (D), which was fed a modified control diet where 3 % of the soybean meal was replaced with an alfalfa protein–xanthophyll preparation (PX). For the rest of the study the kids had ad libitum access to dam milk, hay and their respective diets. After 90 days of rearing (from the end of the fattening period up to when the kids were approximately 120 days of age), five (male) kids were randomly selected from each group and slaughtered. Overall, PX supplementation in goat kids does not affect any parameters of fattening, such as slaughter weight, daily weight gains or dressing percentage. However, beneficial effects of feeding with PX concentrate were found in a higher loin percentage and improved tissue composition resulting from lower fat tissue content. Moreover the PX dietary supplement improved the chemical composition of the muscle tissue by increasing the content of protein and unsaturated fatty acids. Taken together, our results suggest that supplementing the fattening diet for goat kids with the PX preparation did not affect the quantitative parameters of fattening but had a positive influence on the quality of carcass composition.

Legendrian cobordism and Chern–Simons theory on 3-manifolds with boundary

In Floer's instanton homology theory for homology 3-spheres, the ChernSimons function (or a suitable perturbation of it) is used as a sort of Morse function on the space of SU(2) connections modulo gauge equivalence. The chain complex for the homology theory is generated by the critical points, namely the equivalence classes of flat connections, of this function (excepting the trivial connection). In this paper we consider . M, the critical set of the Chern-Simons function on the space of SU(2) connections modulo gauge equivalence for arbitrary oriented 3-manifolds with boundary. Generically, M is a smooth manifold of dimension 3g — 3 except for several types of singularities. These singularities arise from connections which either are reducible on Y or are reducible when restricted to dY. We describe the structure of M near these singularities. There is a natural restriction map from the flat moduli space on the 3manifold to the (6g — 6)-dimensional flat moduli space for its boundary M^. Goldman described a symplectic structure on the latter in [G], and with respect to this structure the restriction map is Lagrangian. In fact, there is a Legendrian lift of the restriction to a U(l) bundle with a contact structure over . ME. The main theorem of the paper, roughly stated, is the following.
Backcasting for Sustainability in the netherlands: Impacts after ten years, policy relevance and a methodological framework

Summary Backcasting: looking back from a desirable future that has been generated first. Since the early 1990s sustainable futures have been explored in backcasting experiments, numerous stakeholders have been involved and steps have been planned in line with the envisioned sustainable futures. But what is the impact of these so-called backcasting experiments ten years later? So far, systematic case studies evaluating backcasting studies after a couple of years and comparing these have hardly been done. This paper reports on the first study that has systematically investigated the follow-up, impacts and spin-off of backcasting experiments in the Netherlands seven to ten years after completion, as well as the organisational and methodological characteristics of the backcasting experiments themselves. It presents three cases: (1) Novel Protein Foods and meat alternatives; (2) Sustainable Households and Nutrition; and (3) Multiple Sustainable Land-use in rural areas. The cases show that participatory backcasting may, but does not automatically lead to substantial follow-up and spin-off. If substantial follow-up has been found after 10 years, it is still at the level of niches. Emergence of niches and spin-off come along with the diffusion of visions originally generated in the backcasting experiment, though they evolve too influenced by the exits and entries of stakeholders. Using innovation and learning theories the factors that affect the emergence of follow-up and new networks could be identified and are discussed, which is followed by providing recommendations for both organisers of participatory backcasting studies, as well as the relevance for policy makers in RTD and sustainable (system) innovations. In addition, the analysis of the three backcasting experiments is used to develop a methodological framework for backcasting involving stakeholders.
Bilingual Dictionary Drafting. The Example of German-Basque, a Medium-density Language Pair

This paper presents a set of Bilingual Dictionary Drafting (BDD) methods including manual extraction from existing lexical databases and corpus based NLP tools, as well as their evaluation on the example of German-Basque as language pair. Our aim is twofold: to give support to a German-Basque bilingual dictionary project by providing draft Bilingual Glossaries and to provide lexicographers with insight into how useful BDD methods are. Results show that the analysed methods can greatly assist on bilingual dictionary writing, in the context of medium-density language pairs.
Assessment of an Industrial Type Radiant Heating System for Drying Rough Rice

Rough rice is normally harvested at moisture contents (MCs) higher than that for safe storage. The objective for this study was to investigate the effectiveness of scaled-up infrared (IR) heating followed by tempering steps to dry freshly-harvested rough rice. An industrial type, pilot scale, IR drying equipment, designed to convey rough rice on a vibrating conveyor belt was used in this study. The heating zone of the equipment had catalytic IR emitters powered by natural gas. Freshly-harvested rough rice of long-grain pureline (cv. Cheniere), long-grain hybrid (cv. 6XP 756) and medium-grain (cv. CL 271) cultivars at initial moisture contents (IMCs) of 23%, 23.5% and 24% w.b, respectively were used. Rough rice samples, at loading rate of 1.61 kg m were heated with IR energy for 30, 50, 90 and 180 s followed by tempering at 60°C for 4 h; the IR heating intensity was 5.55 kW m, at product-to-emitter-gap size of 450 mm, and in oneand two-pass drying operations. The effects of IR treatments followed by tempering on percentage points of moisture removed, head rice yield, energy use, rice color, and pasting characteristics were evaluated. For all the cultivars, percentage point moisture removed increased with increase in IR drying duration. For all rice cultivars, one-pass IR treatments for 180 s resulted in head rice yield significantly lower than that of rice dried using natural air in controlled environment conditions set at 26oC and 65% relative humidity (p < 0.05). Energy required to dry rice increased with increase in drying duration. Viscosity values of all the experimental samples were significantly greater (p value < 0.05) than that of the control samples for all the cultivars except those IR treated for 180 s. There was a significant difference (p<0.05) in the color index (ΔE) of treated samples and the controls. In conclusion, the study provided information crucial to understanding the effects of scaled-up radiant heating and tempering of rough rice on drying rates and rice quality for long-grain pureline, long-grain hybrid and medium-grain rice cultivars.
Screening of verotoxin-producing Escherichia coli (VETC) O104-2011 from Egyptian market in 2011

Escherichia coli strains are important causes of diarrheal disease in the world and remain a major public health problem of animals and human. Sixty seven samples from different kind of food, water, soil and composit were screened for the detection of verotoxin-producing E.coli (VTEC) in the Egyptian markets from different location. Result showed that none of the samples gives positive results for VTEC (O104) ( vt1 and vt2 ) detection. All samples from the Egyptian markets are negative for Vero cyto toxin producing E. coli (O104) with percentage of 100. Keywords: Verotoxin-producing Escherichia coli, Shiga toxins.

An improved tip-loss correction based on vortex code results

Standard blade element momentum(BEM) codes use Prandtl’s tip-loss correction which relies on simpliﬁed vortex theory under the assumption of optimal operating condition and no wake expansion. A new tip-loss correction for implementation in BEM codes has been developed using a lifting-line code to account for the effect of wake expansion, roll-up and distortion under any operating conditions. A database of tip-loss corrections is established for further use in BEM codes. Using this model a more physical representation of the ﬂow and hence a better assessment of the performance of the turbine by BEM codes is expected.
The acyl-CoA thioesterase I (Acot1) is regulated by the peroxisome proliferator-activated receptor alpha and hepatocyte nuclear factor 4 alpha via a distal response element in the promotor

The cytosolic acyl-CoA thioesterase I (Acot1) is an enzyme that hydrolyzes longchain acyl-CoAs of C12-C20-CoA in chain-length, to the free fatty acid and coenzyme A. Acot1 was previously shown to be strongly upregulated at mRNA and protein level in rodents by fibrates. In this study, we show that Acot1 mRNA levels were increased 90-fold in liver by treatment with Wy-14,643 and that Acot1 mRNA is also increased 15-fold in the liver of hepatocyte nuclear factor 4 alpha (HNF4a) knockout animals. Our study identified a direct repeat 1 (DR1) located in the Acot1 gene promotor in mouse, which binds the peroxisome proliferator-activated receptor alpha (PPARa) and the HNF4a . Chromatin immunoprecipitation assay (ChIP) showed that the identified DR1 bound PPARa/retinoid X receptor alpha (RXRa) and HNF4a, whereas the binding in ChIP was abrogated in the PPARa and HNF4a knockout mouse models. Reporter gene assays showed activation of the Acot1 promotor in cells by the PPARa agonist Wy-14,643, following co-transfection with PPARa/RXRa. However, transfection with a plasmid containing HNF4a also resulted in an increase in promotor activity. Taken together, these data show that Acot1 is under regulation by an interplay between of HNF4a and PPARa.
Actual Application of a H2-Based Polyvinyl Chloride Hollow Fiber Membrane Biofilm Reactor to Remove Nitrate from Groundwater

To evaluate the actual performance of the H2-based polyvinyl chloride hollow fiber membrane biofilm reactor (HF-MBfR), we used HF-MBfR to remove nitrate from the nitrate contaminated groundwater with the dissolved oxygen (~6.2 mg/L) in Zhangqiu city (Jinan, China). The reactor was operated over 135 days with the actual nitrate contaminated groundwater. The result showed that maximum of nitrate denitrification rate achieved was over 133.8 g -N/m3d (1.18 g -N/m2d) and the total nitrogen removal was more than 95.0% at the conditions of influent nitrate 50 mg/L, hydrogen pressure 0.05 MPa, and dissolved oxygen (DO) 6.2 mg/L, with the nitrate in effluent under the value limits of drinking water. The fluxes analysis showed that the electron-equivalent fluxes of nitrate, sulfate, and oxygen account for about 81.2%, 15.2%, and 3.6%, respectively, which indicated that nitrate reduction could consume more electrons than that of sulfate reduction and dissolved oxygen reduction. The nitrate reduction was not significantly influenced by sulfate reduction and the dissolved oxygen reduction. Based on the actual groundwater quality on site, the Langelier Saturation Index (LSI) was 0.4, and the membrane could be at the risk of surface scaling.
Product market competition and unionized wage

Considering a move from monopoly to duopoly, Bastos et al. ("Open shop unions and product market competition", 2010, Canadian Journal of Economics) provides open-shop union, where the union density is less than one, as a theoretical reason for the evidence of a positive relationship between product market competition and unionized wage. We show that their theoretical result is very much sensitive to the assumption of initial monopoly. Using the right-to-manage-model of labor union and generalizing their work with multiple unionized and non-unionized firms, we show that if there are at least two firms initially, higher product market competition reduces unionized wage, irrespective of the union density, bargaining power of the union and the union's preference for wage and employment. We then provide a simple reason for the unionized wage increasing effect of product market competition based on external economies of scale.
A QoE-Aware Scheduler for OFDMA Networks

In this paper, we present a Quality of Experience (QoE)-aware scheduler aiming at maximizing the minimum Mean Opinion Score (MOS) in a system subject to attaining at least a minimum number of satisfied users. Different of the benchmarking solution, the proposed one takes into account all the data that the User Equipments (UEs) have already received, and not only the data of a specific instant of time, thus suitably excluding UEs already satisfied. According to simulation results, the proposed solution not only improves the users’ satisfaction and the minimum experienced MOS in the system, but it also doubles the capacity in terms of supported number of users compared to benchmarking solution. It is also able to handle imperfections on the Channel State Information (CSI).
Tring! Tring! usability study of a voice based information system

In developing regions, voice based telecommunication services are one of the most appropriate medium for information dissemination as they overcome prevalent low literacy rate and are more reachable than any other medium. However, voice based Interactive Voice Response (IVR) systems are still not exploited to their full potential and are commonly considered as frustrating to use. We did a real world experiment to investigate the usability issues of a voice based system. In this paper, we report content usage of our experimental IVR and interface difficulties as experienced by the user. We also highlight the user behavior towards accessing critical and non-critical information over multiple information media vis-a-vis IVR, web and talking to a human on the phone. Findings from the post-study survey reveal that people trust web more than human and IVR. We believe, our results can be used for efficient development of future IVR systems.
The Effect of Pre-Sowing Plants on Amount of the Soil Organic Matter

The vegetation is one of the factors that are active soil building. Cover crop is a general term that encompasses a wide range of plants that are cultivated with different ecological reasons. To evaluate the effect of pre-cultured plants on increasing of a soil organic matter, the experiment base on randomized complete block design was performed. The factors included perko, oily radish and composition of clover with phacelia. According to the analysis of variance there was significant difference (P<0.01) between plants at dry and green fodder and also there was significant difference (P<0.05) between plants at nitrogen, protein and digestible protein percentage, but did not significant difference between treatments at soil organic matter. The mean comparison results showed that the highest amount of green fodder obtained at oily radish, the highest dried fodder obtained at perko and oily radish and the highest nitrogen, protein and digestible protein percentage obtained at perko.
Gate-Tunable Quantum Dot in a High Quality Single Layer MoS$_{\mathrm{2}}$ Van der Waals Heterostructure

We have fabricated an encapsulated monolayer MoS$_{\mathrm{2}}$ device with metallic ohmic contacts through a pre-patterned hBN layer. In the bulk, we observe an electron mobility as high as 3000 cm$^{\mathrm{2}}$/Vs at a density of 7 $\times$ 10$^{\mathrm{12}}$ cm$^{\mathrm{-2}}$ at a temperature of 1.7 K. Shubnikov-de Haas oscillations start at magnetic fields as low as 3.3 T. By realizing a single quantum dot gate structure on top of the hBN we are able to confine electrons in MoS$_{\mathrm{2}}$ and observe the Coulomb blockade effect. By tuning the middle gate voltage we reach a double dot regime where we observe the standard honeycomb pattern in the charge stability diagram.
Optical structure and star formation in blue compact dwarf galaxies. II. Relations between photometric components and evolutionary implications.

— We present new B and R CCD surface photometry for a sample of 4 Blue Compact Dwarf Galaxies (BCDs) and 2 higher luminosity starburst galaxies. We find that the BCD surface brightness profiles (SBPs) can be generally well fitted by the sum of the light of 3 distinct components: 1) an exponential component at large radii, with or without a central flattening which describes the underlying older stellar population; 2) a plateau component at intermediate radii and 3) a gaussian component at small radii. The last 2 components describe the ongoing starburst superimposed on the older stellar component. We apply the 3-component decomposition scheme to 8 more BCDs from the literature and, for the total sample of 14 galaxies, derive structural properties such as central surface brightness and scale length, and perform a deprojection to obtain the luminosity density distribution for each component. We also derive B — R color profiles and find that BCDs show generally a reddening outwards, followed by a blueing beyond a transition radius.
Simplified mantle architecture and distribution of radiogenic power

The mantle components that represent the source region of ocean island basalts (OIB) and feed hotspot volcanism are predicted to contain 160 ± 20 (2σm) ng/g Th, a heat‐producing element. This critical model composition indicates that the OIB source region (OSR) comprises a significant amount of recycled oceanic crust and constitutes 19+3−2 (2σm)% of the mantle by mass. The mass fraction of this reservoir supports a mantle architecture with a basal thermochemical layering at an average depth of 2000 ± 100 (2σm) km or two thermochemical piles that extend up to midmantle levels. The hotspot source described here generates 10 pW/kg of radiogenic heat and supplies 7.3 TW to the planet's total surface heat flux. Given that the silicate portion of the Earth produces some 20.4 TW of radiogenic power, with 7.2 TW derived from the continental crust, the mantle source responsible for mid‐ocean ridge volcanism provides only 5.9 TW of radiogenic power (or <2 pW/kg). As a result, the source of hotspots generates >5x more radiogenic heat than the source of mid‐ocean ridges, thus contributing to the energetics that drive mantle convection and potentially the formation of long‐lived plumes via bottom heating of the modern mantle. The potential for a sequestered or unsampled mantle reservoir would impact the relative mass fractions of the source regions of OIB and mid‐ocean ridge volcanism but not the compositional model of the OSR presented here.

Financial Strength Characteristics of Firms: An Explanation of the P/E Anomaly?

The P/E anomaly is the widely accepted proposition that even after adjusting for risk as mea-sured by beta, low P/E stocks have higher returns than high P/E stocks. The literature includes substantial evidence supporting the proposition. Recent research has examined the small-firm effect, the January effect, and methodological issues in an attempt to explain the P/E anomaly. This study examines the P/E anomaly from 1986-90 using a mean cross-sectional regression analysis. The findings indicate the P/E anomaly is present only on NYSE stocks and is largely explained by financial strength characteristics, consistent with Chan and Chen' s (1991) marginal firm hypothesis.
Efficient Emulators for Multivariate Deterministic Functions

One of the challenges with emulating the response of a multivariate function to its inputs is the quantity of data that must be assimilated, which is the product of the number of model evaluations and the number of outputs. This article shows how even large calculations can be made tractable. It is already appreciated that gains can be made when the emulator residual covariance function is treated as separable in the model-inputs and model-outputs. Here, an additional simplification on the structure of the regressors in the emulator mean function allows very substantial further gains. The result is that it is now possible to emulate rapidly—on a desktop computer—models with hundreds of evaluations and hundreds of outputs. This is demonstrated through calculating costs in floating-point operations, and in an illustration. Even larger sets of outputs are possible if they have additional structure, for example, spatial-temporal.
