description: The aim of the study was to identify and prioritize the most important characteristics affecting consumer assessment of the quality for different types of meats and fish, as well as the impact of these traits on the process making a decision to purchase meat and fish. The research material came from nationwide quantitative survey conducted in 2012 on a sample of 1,500 respondents Polish adult population in 16 provinces, proportion to the number of their inhabitants. Polish consumer , despite changing over the years, consumption patterns and habits nutrition, it is still a supporter of pork, which is about 60% of total meat consumption. Was reduced beef consumption. In the years 1990-2013 increased consumption of poultry meat with nearly 20 kg/person/year. One of the determinants influencing the consumer behavior with respect to meat is its quality, especially way of perceiving, characterization and evaluation by consumers. As shown the results of a quantitative empirical study, Polish consumers rarest declared consuming venison, fish and beef. Moreover, the other is the power of the individual characteristics consumer assessment of the quality to take a final decision on buying meat and fish. For most consumers, the most important distinguishing feature was general appearance. For people buying pork important feature was the content fat. Respondents purchasing beef pointed to its price and the buyer assessed fish smell them.

description: Given the importance of dairy in Asia and its diverse characteristics, stakeholders have proposed to create dairy platform to facilitate sharing of knowledge and experiences. A review of several existing regional and global multi-stakeholder platforms reveal that there is no single model for organizing and managing a platform or forum or alliance for joint action across countries. And participation from the Asia-Pacific region in the established regional and global platforms related to livestock and/or dairy is minimal partly because priority of those platforms is to address problems and issues facing the developed country dairy industries and partly because of lack of resources of many small stakeholders in the region to widely and actively engage in those platforms. Therefore there is a need for creating a voluntary open platform by stakeholders in the region to (a) Promote dialogue towards enhancing common understanding of development issues and their solutions,(b) build consensus on the role of dairy towards sustainable food security and nutrition and (c)catalyse stakeholder commitments to action and on-the-ground improvements through exchange and dissemination of knowledge and experience. The paper outlines various issues and options for building such a platform.

description: Combinatorial Testing (CT) is an effective testing strategy which has seen increased adoption in the field of software testing. As a black-box testing technique it concerns itself with generating input test cases able to provide mathematical input-space coverage guarantees while keeping the number of test cases low. Generating optimal combinatorial test sets is believed to be a hard optimization problem which has spurred the development of several greedy algorithms which trade-off optimality for speed. One of the most popular representatives is the In-Parameter-Order family of algorithms. This class of algorithms has seen a wide adoption in including software, hardware and security testing as they are able to construct test sets for most instances occurring in practice. In this thesis, an efficient design of the In-Parameter-Order algorithms is presented which drastically reduces the time and required memory to compute combinatorial test sets. The improved theoretical design is implemented in a prototype and benchmarked against the state of the art implementation. Furthermore, the algorithms are made available in a general purpose test generation tool developed for this thesis which is open and free to use by anyone. The thesis also studies the impact of tie-breaking, parameter ordering and tuple enumeration order on the resulting test sets. An extensive experimental study shows that different tie-breakers have no significant impact on average and that ordering parameters in order of descending domain size can lead to drastically smaller test sets.
Cirsimaritin Alleviates Colitis-Induced Inflammation and Oxidative Stress in Rats: Mechanistic Insights and Therapeutic Potential.

Subjects: subject: Medicine and Health Sciences

description: Objective: The objective of this study was to explore the efficacy of cirsimaritin, a natural dimethoxy flavone, in treating colitis-induced complications such as inflammation, oxidative stress, apoptosis, and histopathological changes in a rat model.
Methods: The study involved 56 male Wistar rats, divided into seven groups, to assess the effects of various concentrations of cirsimaritin (10, 20, 40, and 80 mg/kg) against a control group and a standard treatment group (dexamethasone). The rats underwent colitis induction, followed by the administration of the treatments. Parameters measured included Total Antioxidant Capacity (TAC), activities of antioxidant enzymes (SOD and CAT), levels of oxidative stress markers (MDA and NO), and expression of several inflammatory and apoptotic genes (IL-6, IL-1β, TNF-α, TLR4, INOS, NF-κB, Bax, Bcl-2, Caspase-3, and Caspase-8). Additionally, histopathological evaluations of the colon tissues were conducted.
Results: The induction of colitis resulted in decreased TAC and antioxidant enzyme activities (SOD: p < .05, CAT: p < .05), and increased levels of oxidative stress markers (MDA: p < .05, NO: p < .01). Elevated expressions of inflammatory (IL-6, IL-1β, TNF-α, TLR4, INOS, NF-κB) and apoptotic genes (Bax, Caspase-3, Caspase-8) were noted, with significant differences from control values (p < .001 for most genes). Treatment with cirsimaritin significantly ameliorated these effects, enhancing TAC and antioxidant enzyme activities (SOD and CAT activities at 40 and 80 mg/kg: p < .05), and reducing the levels of MDA and NO (p < .05 at 80 mg/kg). Notably, cirsimaritin at higher doses (40 and 80 mg/kg) more effectively decreased the expression of inflammatory and apoptotic genes (p < .01 to p < .001). Histopathological examinations revealed significant improvements in colon tissue integrity in the cirsimaritin-treated groups compared to the colitis group.
Conclusion: Cirsimaritin could be a therapeutic approach for colitis treatment.

Large scale computer calculations reproduce the overall ground state phase diagram of the high-temperature superconductors as well as the one-particle excitation spectra for both hole- and electron-doping. We identify clear signatures of the Mott gap as well as of AF and of dSC that should be observable in photoemission experiments.

description: Different studies have been demonstrated that the surface integrity of substrate bulk materials to be coated has a significant impact on the adhesion of thermally sprayed coatings. It is known that the surface integrity of parts processed by selective laser melting (SLM) differs from those obtained from bulk materials. Although 316L stainless steel is among the most investigated material for SLM, the adhesion of thermally sprayed coatings on 316L stainless steel substrates processed by SLM has not been studied yet. This study aims at evaluating the effect of various mechanical pre-treatments onto 316L stainless steel substrates processed by SLM and their effect on the adhesion of high velocity oxy-fuel (HVOF)-sprayed WC-Co coatings. To differentiate between topographical effects and residual stress-related phenomena, a stress-relief heat treatment of the SLM substrates served as a reference throughout the investigations. The differently pre-treated SLM substrates were investigated with regard to the surface roughness and residual stresses. For the HVOF-sprayed SLM composites, Vickers interfacial indentation tests were conducted to assess the resulting coating adhesion. The findings demonstrated that the HVOF-sprayed WC-Co coatings predominantly exhibit good adhesion to the SLM 316L substrates. However, it was found that the stress state in the SLM 316L substrate surface is more likely to affect the adhesion of the WC-Co coating, while the substrate surface roughness showed a marginal effect.

description: We present a specific model for cosmological inflation driven by the Liouville field in a non-critical supersymmetric string framework, in which the departure from criticality is due to open strings stretched between the two moving Type-II 5-branes. We use WMAP and other data on fluctuations in the cosmic microwave background to fix parameters of the model, such as the relative separation and velocity of the 5-branes, respecting also the constraints imposed by data on light propagation from distant gamma-ray bursters. The model also suggests a small, relaxing component in the present vacuum energy that may accommodate the breaking of supersymmetry.

description: Context: The software development industry is rapidly adopting machine learning for transitioning modern day software systems towards highly intelligent and self-learning systems. However, the full potential of machine learning for improving the software engineering life cycle itself is yet to be discovered, i.e., up to what extent machine learning can help reducing the effort/complexity of software engineering and improving the quality of resulting software systems. To date, no comprehensive study exists that explores the current state-of-the-art on the adoption of machine learning across software engineering life cycle stages. Objective: This article addresses the aforementioned problem and aims to present a state-of-the-art on the growing number of uses of machine learning in software engineering. Method: We conduct a systematic mapping study on applications of machine learning to software engineering following the standard guidelines and principles of empirical software engineering. Results: This study introduces a machine learning for software engineering (MLSE) taxonomy classifying the state-of-the-art machine learning techniques according to their applicability to various software engineering life cycle stages. Overall, 227 articles were rigorously selected and analyzed as a result of this study. Conclusion: From the selected articles, we explore a variety of aspects that should be helpful to academics and practitioners alike in understanding the potential of adopting machine learning techniques during software engineering projects.

description: We present extensive radio observations of SN 2003L, the most luminous and energetic Type Ibc radio supernova with the exception of SN 1998bw (associated with GRB 980425). Observations from the Very Large Array are well described by a fitting a synchrotron self-absorption model to the emission spectrum. This model implies a sub-relativistic ejecta velocity, v ~ 0.2c, and a size of r ~ 4.3 x 10^{15} cm at t ~ 10 days. The circumstellar density is suitably fit with a stellar wind profile, n_e ~ r^{-2} and a constant mass loss rate of M_dot ~ 7.5 x 10^{-6} M_{solar}/year. Moreover, the magnetic field follows B ~ r^{-1} and the kinetic energy of the radio bright ejecta is roughly E ~ 10^{48} erg assuming equipartition of energy between relativistic electrons and magnetic fields. Furthermore, we show that free-free absorption does not contribute significantly to the radio spectrum, since it implies ejecta velocities which are inconsistent with size constraints derived from Very Long Baseline Array observations. In conclusion, we find that although SN 2003L has a radio luminosity comparable to that seen in SN 1998bw, it shows no evidence for a significant amount of energy coupled to relativistic ejecta. Using SN 2003L as an example, we comment briefly on the coupling of ejecta velocity and energy in Type Ibc supernovae.

description: We consider the univalence superselection rule. One would say perhaps ``There is no indication in nature to invalidate this rule. Fermions do not condensate!'' To explain our motivation, let us recall the correspondence of fermion systems and Pauli systems by the Jordan-Wigner transformation. For a finite lattice, fermion grading symmetry corresponds to the Pauli grading. For an infinite lattice, the Pauli-grading can be spontaneously broken e.g. for the XY-model. What is the status of the fermion grading? Nature tells that fermion grading symmmetry cannot be broken for any physical model. But it seems that its rigorous support is needed.

description: This article presents a procedure for estimating sales loss following a food contamination incident with application to the case of heptachlor contamination of fresh fluid milk in Oahu, Hawaii in 1982. A major finding is that media coverage following the incident had a significant impact on milk purchases and that negative coverage had a larger effect than positive coverage. This conclusion implies that public statements by producers or government to assure the public of safe food supplies may be ineffective in restoring consumer confidence following the discovery of a food safety problem.

Integrated investigation of natural attenuation in a petroleum hydrocarbon contaminated aquifer
Creators: name: Amos, Richard Theodule
Publisher: name: University of British Columbia
Year: 2010

description: This research investigates natural attenuation processes at a crude oil spill site near Bemidji, MN, with a focus on the contribution of methanogenesis. An important aspect of this work is evaluating the use of naturally occurring gases in the saturated and unsaturated zones to aid in the assessment of methane production rates, the fate of methane, and more generally to quantitatively assess the effect of gas production in source zones on contaminant release and attenuation. Field data from the Bemidji site demonstrate that naturally occurring stable gases such as Ar and N₂ can be effectively used to better understand and quantify physical and chemical processes related to methanogenic activity. These include biochemically induced gas advection in the unsaturated zone, degassing and gas bubble formation due to methanogenic gas production in the saturated source zone, and attenuation of dissolved gases in the groundwater plume. To allow a more quantitative assessment, the reactive transport code MIN3P has been enhanced to simulate bubble production, bubble entrapment due to water table rise, and permeability changes due to trapped bubbles. Simulations for a hypothetical case study suggest that these processes work to attenuate the dissolved gas plume emanating from the source zone. A detailed simulation, constrained by Bemidji field data, is conducted to provide an integrated assessment of natural attenuation processes in the unsaturated and saturated zones. Although gas bubble ebullition is potentially an important process at the site, it could not be included in the site-specific simulations, because this process is poorly understood and not well constrained by field data. To investigate this process, column experiments were conducted that show clear evidence for ebullition from a methanogenic environment, using dissolved gas concentrations to monitor the extent and rate of ebullition. An empirically derived formulation describing ebullition, integrated into MIN3P, provides insights into the parameters controlling ebullition and allows the process to be quantified. Overall, this work contributes to a better understanding of natural attenuation processes in contaminated aquifers and offers novel field and modeling techniques to investigate and quantify these processes.

description: We examine a sample of low redshift (10 < d < 150 Mpc) galaxies including galaxies with r-band absolute magnitudes as faint as -12.5 (for h=1), selected from the Sloan Digital Sky Survey Data Release 2 (SDSS). The sample is unique in containing galaxies of extremely low luminosities in a wide range of environments, selected with uniform and well-understood criteria. We present the luminosity function as well as the broad-band properties of low luminosity galaxies in this sample. A Schechter function is an insufficient parameterization of the r-band luminosity function; there is an upturn in the slope at low luminosities. The resulting slope at low luminosities in this sample is around -1.3. However, we almost certainly miss a large number of galaxies at very low luminosities due to low surface brightness selection effects, and we estimate that the true low luminosity slope may be as steep or steeper than -1.5. The results here are consistent with previous SDSS results and, in the g-band, roughly consistent with the results of the Two degree Field Galaxy Redshift Survey. Extremely low luminosity galaxies are predominantly blue, low surface brightness, exponential disks.

description: To send encrypted emails, users typically need to create and exchange keys which later should be manually authenticated, for instance, by comparing long strings of characters. These tasks are cumbersome for the average user. To make more accessible the use of encrypted email, a secure email application named pEp automates the key management operations; pEp still requires the users to carry out the verification, however, the authentication process is simple: users have to compare familiar words instead of strings of random characters, then the application shows the users what level of trust they have achieved via colored visual indicators. Yet, users may not execute the authentication ceremony as intended, pEp's trust rating may be wrongly assigned, or both. To learn whether pEp's trust ratings (and the corresponding visual indicators) are assigned consistently, we present a formal security analysis of pEp's authentication ceremony. From the software implementation in C, we derive the specifications of an abstract protocol for public key distribution, encryption and trust establishment; then, we model the protocol in a variant of the applied pi calculus and later formally verify and validate specific privacy and authentication properties. We also discuss alternative research directions that could enrich the analysis.

description: We investigate stationary spherically symmetric accretion of the relativistic Vlasov gas on Reissner-Nordström black holes. The model is based on a recent analysis done by Rioseco and Sarbach for the Schwarzschild spacetime. Both models share many common features: The gas characterized by the Maxwell-Jüttner distribution at infinity is no longer in thermal equilibrium in the vicinity of the black hole. The radial pressure at the black-hole horizon can be even an order of magnitude smaller than the tangential pressure. Quantitative characteristics of the Reissner-Nordström model depend on the charge parameter. For black holes with fixed asymptotic mass, the mass accretion rate decreases with the increasing black-hole charge. The ratio of the tangential pressure to the radial pressure at the horizon also decreases with the increasing charge. On the other hand, the particle density at the horizon (normalized by its asymptotic value) grows with the black-hole charge parameter.

description: We investigate two-dimensional Wess-Zumino models in the continuum and on spatial lattices in detail. We show that a non-antisymmetric lattice derivative not only excludes chiral fermions but in addition introduces supersymmetry breaking lattice artifacts. We study the nonlocal and antisymmetric SLAC derivative which allows for chiral fermions without doublers and minimizes those artifacts. The supercharges of the lattice Wess-Zumino models are obtained by dimensional reduction of Dirac operators in high-dimensional spaces. The normalizable zero modes of the models with N=1 and N=2 supersymmetry are counted and constructed in the weak- and strong-coupling limits. Together with known methods from operator theory this gives us complete control of the zero mode sector of these theories for arbitrary coupling.

description: Corneal cross-linking (CXL) using UVA irradiation with a riboflavin photosensitizer has grown from an interesting concept to a practical clinical treatment for corneal ectatic diseases globally, such as keratoconus. To characterize the corneal structural changes, existing methods such as X-ray microscopy, transmission electron microscopy (TEM), histology and optical coherence tomography have been used. However, these methods have various drawbacks such as invasive detection, the impossibility for in vivo measurement, or limited resolution and sensitivity to structural alterations. Here, we report the application of over-sampling nano-sensitive optical coherence tomography (nsOCT) method for probing the corneal structural alterations. The results indicate that the spatial period increases slightly after 30 minutes riboflavin instillation but decreases significantly after 30 min UVA irradiation following the Dresden protocol. The proposed non-invasive method can be implemented using existing OCT system, without any additional components, for detecting nanoscale changes with the potential to assist diagnostic assessment during CXL treatment, and possibly to be a real-time monitoring tool in clinics.

description: For continuous-variable systems, we introduce a measure of entanglement, the continuous variable tangle ({\em contangle}), with the purpose of quantifying the distributed (shared) entanglement in multimode, multipartite Gaussian states. This is achieved by a proper convex roof extension of the squared logarithmic negativity. We prove that the contangle satisfies the Coffman-Kundu-Wootters monogamy inequality in all three--mode Gaussian states, and in all fully symmetric $N$--mode Gaussian states, for arbitrary $N$. For three--mode pure states we prove that the residual entanglement is a genuine tripartite entanglement monotone under Gaussian local operations and classical communication. We show that pure, symmetric three--mode Gaussian states allow a promiscuous entanglement sharing, having both maximum tripartite residual entanglement and maximum couplewise entanglement between any pair of modes. These states are thus simultaneous continuous-variable analogs of both the GHZ and the $W$ states of three qubits: in continuous-variable systems monogamy does not prevent promiscuity, and the inequivalence between different classes of maximally entangled states, holding for systems of three or more qubits, is removed.

A new continuum dynamic model for the analysis of extremely rapid landslide motion across complex 3D terrain
Creators: name: McDougall, Scott
Publisher: name: University of British Columbia
Year: 2010

description: Runout analysis, the prediction of landslide motion and its effects, is an essential component of landslide risk assessment. A new continuum dynamic model has been developed for the runout analysis of extremely rapid, flow-like landslides, including rock avalanches, debris avalanches, debris flows and flow slides. The new model, DAN3D, is a 3D extension of the existing 2D model DAN. It uses a meshless, Lagrangian numerical method adapted from Smoothed Particle Hydrodynamics to discretize and solve the depth-averaged equations of motion for an "equivalent fluid", a hypothetical material governed by simple rheological relationships. The required rheological parameters, rather than measured, are calibrated through back-analysis of real landslide case studies. The key capabilities of the model include: 1) the ability to simulate motion across complex 3D terrain without the need to input a pre-defined path direction or width and without introducing problems due to mesh distortion; 2) the ability to simulate strain-dependent, non-hydrostatic, anisotropic internal stresses due to 3D deformation of material with internal shear strength; 3) the ability to simulate mass and momentum transfer due to entrainment of path material; 4) the ability to simulate variations in rheology along the path and within the landslide; and 5) efficient and simple operation. The model outputs the simulated spatial distribution of hazard intensity parameters, including flow velocity and depth, which are required for delineating the potential impact area, estimating the vulnerability of elements within this area and designing protective measures. It has been tested using both analytical and experimental methods, and its general behaviour has been demonstrated using a series of simple parametric analyses. The model has also been applied at full-scale to the simulation of a wide variety of landslide types. These back-analyses form the basis for a more thorough calibration, but some useful patterns have already emerged. This experience has been applied in practice to landslide runout prediction, although so far only in a parametric way. With continued back-analysis of real cases and the development of a probabilistic approach to forward-analysis, true landslide runout prediction, including quantification of uncertainty, should eventually be possible using the new model.

description: We present observations of $^{12}$C$^{32}$S, $^{12}$C$^{34}$S, $^{13}$C$^{32}$S and $^{12}$C$^{33}$S J=2$-$1 lines toward a large sample of massive star forming regions by using the Arizona Radio Observatory 12-m telescope and the IRAM\,30-m. Taking new measurements of the carbon $^{12}$C/$^{13}$C ratio, the $^{32}$S$/$$^{34}$S isotope ratio was determined from the integrated $^{13}$C$^{32}$S/$^{12}$C$^{34}$S line intensity ratios for our sample. Our analysis shows a $^{32}$S$/$$^{34}$S gradient from the inner Galaxy out to a galactocentric distance of 12\,kpc. An unweighted least-squares fit to our data yields $^{32}$S$/$$^{34}$S = (1.56 $\pm$ 0.17)$\rm D_{\rm GC}$ + (6.75 $\pm$ 1.22) with a correlation coefficient of 0.77. Errors represent 1$σ$ standard deviations. Testing this result by (a) excluding the Galactic center region, (b) excluding all sources with C$^{34}$S opacities $>$ 0.25, (c) combining our data and old data from previous study, and (d) using different sets of carbon isotope ratios leads to the conclusion that the observed $^{32}$S$/$$^{34}$S gradient is not an artefact but persists irrespective of the choice of the sample and carbon isotope data. A gradient with rising $^{32}$S$/$$^{34}$S values as a function of galactocentric radius implies that the solar system ratio should be larger than that of the local interstellar medium. With the new carbon isotope ratios we obtain indeed a local $^{32}$S$/$$^{34}$S isotope ratio about 10$\%$ below the solar system one, as expected in case of decreasing $^{32}$S$/$$^{34}$S ratios with time and increased amounts of stellar processing. However, taking older carbon isotope ratios based on a lesser amount of data, such a decrease is not seen. No systematic variation of $^{34}$S$/$$^{33}$S ratios along galactocentric distance was found.

description: This paper explores the role of IPR protection in the emergence of R&D linkages from newly emerging economies. Using data from a new survey on Chinese and Indian firms in the ICT sector, we find IPR protection to be key in the engagement of Southern firms in global innovation networks. A complementary exercise uses global bilateral patent data to investigate the location-specificity of IPR enforcement for this phenomenon. We find that a stringent IPR regime in the North (South) discourages (encourage) foreign patenting activities of firms in the South, suggesting that a global convergence of IPRs can stimulate Southern innovation.

description: Here we present the New York University Value-Added Galaxy Catalog (NYU-VAGC), a catalog of local galaxies (mostly below a redshift of about 0.3) based on a set of publicly-released surveys (including the 2dFGRS, 2MASS, PSCz, FIRST, and RC3) matched to the Sloan Digital Sky Survey (SDSS) Data Release 2. Excluding areas masked by bright stars, the photometric sample covers 3514 square degrees and the spectroscopic sample covers 2627 square degrees (with about 85% completeness). Earlier, proprietary versions of this catalog have formed the basis of many SDSS investigations of the power spectrum, correlation function, and luminosity function of galaxies. We calculate and compile derived quantities (for example, K-corrections and structural parameters for galaxies). The SDSS catalog presented here is photometrically recalibrated, reducing systematic calibration errors across the sky from about 2% to about 1%. We include an explicit description of the geometry of the catalog, including all imaging and targeting information as a function of sky position. Finally, we have performed eyeball quality checks on a large number of objects in the catalog in order to flag deblending and other errors. This catalog is complementary to the SDSS Archive Servers, in that NYU-VAGC's calibration, geometrical description, and conveniently small size are specifically designed for studying galaxy properties and large-scale structure statistics using the SDSS spectroscopic catalog.

description: We report on low-temperature MOVPE growth of silicon delta-doped \b{eta}-Ga2O3 films with low FWHM. The as-grown films are characterized using Secondary-ion mass spectroscopy, Capacitance-Voltage and Hall techniques. SIMS measurements show that surface segregation is the chief cause of large FWHM in MOVPE-grown films. The surface segregation coefficient (R) is observed to reduce with reduction in the growth temperature. Films grown at 600 °C show an electron concentration of 9.7 x 1012 cm-2 and a FWHM of 3.2 nm. High resolution scanning/transmission electron microscopy of the epitaxial film did not reveal any significant observable degradation in crystal quality of the delta sheet and surrounding regions. Hall measurements of delta-doped film on Fe-doped substrate showed a sheet charge density of 6.1 x 1012 cm-2 and carrier mobility of 83 cm2/V. s. Realization of sharp delta doping profiles in MOVPE-grown \b{eta}-Ga2O3 is promising for high performance device applications.

description: In this paper we study theoretically and empirically the role of the interaction between skilled migration and intellectual property rights (IPRs) protection in determining innovation in developing countries (South). We show that although emigration from the South may directly result in the well-known concept of brain drain, it also causes a brain gain effect, the extent of which depends on the level of IPRs protection in the sending country. We argue this to come from a diaspora channel through which the knowledge acquired by emigrants abroad can flow back to the South and enhance the skills of the remaining workers there. By increasing the size of the innovation sector and the skill-intensity of emigration, IPRs protection makes it more likely for diaspora gains to dominate, thus facilitating a potential net brain gain. Our main theoretical insights are then tested empirically using a panel dataset of emerging and developing countries. The findings reveal a positive correlation between emigration and innovation in the presence of strong IPRs protection.
