description: This article discusses tests of CPT and Lorentz invariance with data from the muon g-2 experiment at Brookhaven National Laboratory. According to an extension of the Standard Model by Kostelecky et al., CPT/Lorentz violating terms in the Lagrangian induce a shift of the anomaly frequency omega_a of muons in a magnetic field. This shift is predicted to be different for positive and negative muons and to oscillate with the Earth's sidereal frequency. We discuss the sensitivity of the g-2 experiment to different parameters of this Standard Model extension and propose an analysis method to search for sidereal variations of omega_a.

description: Cross-correlation analysis of the thermal Sunyaev-Zel'dovich (tSZ) effect and weak gravitational lensing (WL) provides a powerful probe of cosmology and astrophysics of the intra-cluster medium. We present the measurement of the cross-correlation of tSZ and WL from Planck and Subaru Hyper-Suprime Cam. The combination enables us to study cluster astrophysics at high redshift. We use the tSZ-WL cross-correlation and the tSZ auto-power spectrum measurements to place a tight constraint on the hydrostatic mass bias, which is a measure of the degree of non-thermal pressure support in galaxy clusters. With the prior on cosmological parameters derived from the analysis of the cosmic microwave background anisotropies by Planck and taking into account foreground contributions both in the tSZ auto-power spectrum and the tSZ-WL cross-correlation, the hydrostatic mass bias is estimated to be $26.9^{+8.9}_{-4.4} \%$ ($68\%$ C.L.), which is consistent with recent measurements by mass calibration techniques.

description: Leptocera gongylotheca Buck, new species
(Figs. 69–75)
 Description. Indistinguishable from L. argentinica sp.n. except for the shape of the female spermathecae (Fig. 74): Spermatheca perfectly spherical, lacking narrow, ridged, subcylindrical basal section; entire surface (except very base) bumpy. Male terminalia as in Figs. 69–72, female terminalia as in Figs. 73–75.
 Type material. Holotype ♀ and 13 ♂♂, 12 ♀♀ paratypes (DEBU): ARGENTINA, Prov. Salta, Santa Rosa de Tastil 100 km W Salta, 3,000 m, 21.ii.1992, very dry along creek, S.A. Marshall. Note: The identity of all except one female was confirmed through dissection. Males cannot be distinguished from L. argentinica sp.n. (males unassociated with females are listed under L. argentinica sp.n.).
 Etymology. The species name is a noun in apposition and refers to the diagnostic, spherical spermathecae (Gr. gongylos: round, spherical).
 Distribution. Only known from the type locality in northern Argentina (Salta Province) where it occurs together with its sibling species L. argentinica sp.n.
 Discussion. We were uncertain at first how to interpret the puzzling case of spermathecal variation presented by L. argentinica / gongylotheca sp.n. species pair. It seems clear that the different spermathecal shapes do not represent different developmental stages (e.g., pre- or post-insemination) since there are no intermediate stages, and the spermathecal base of the elongate type (here described as L. argentinica sp.n.) is just as sclerotized and inflexible as the remainder of the spermathecal body. We decided against interpreting the different shapes as a case of structural polymorphism (unknown so far in spermathecae of Sphaeroceridae) because in the L. caenosa group there is another example of the exact same type of variation (spherical vs. elongate spermathecae), which in this case is undoubtedly due to specific distinctness (L. erythrocera and L. sphaerotheca sp.n.). In this species pair the spermathecal differences are correlated with one external character (length of posteroapical bristles of mid tibia) as well as ecological differences (L. sphaerotheca sp.n. occurs at higher altitudes than L. erythrocera; see Discussion under L. sphaerotheca sp.n.).

Influences of Antroquinonol and 4-Acetylantroquinonol B on Inflammatory Tumorigenesis in the MCF-7 Breast Cancer Cell Line with or without TNF-α Stimulation
Creators: name: Lin, Ting-Chun

description: Breast cancer (BC) is one of the most common cancers among women worldwide that ~25% of new cancer cases diagnosed every year would be BC; moreover, ~15% of cancer deaths per year caused by BC makes it the leading cause of cancer death among women worldwide. To date, though the cause of a large proportion of BC are still unclear, recent studies have revealed that a supportive breast tissue microenvironment is critical for the development and progression of BC, especially the communication with immune cells within breast tissue. Therefore, breast inflammatory microenvironment is currently received a substantial attention in the prevention and treatment of BC. Research on breast cancer immunology suggests that inflammatory mediators, estrogen and several inflammation-related tumorigenic pathways are potentially contributors for inflammatory breast tumorigenesis. It is evidenced that elevated levels of inflammatory mediators, such as cytokines, chemokines, prostaglandins, and enhanced estrogen production while suffering from chronic inflammation is responsible for not only activating oncogenic pathways, for example NF-κB, STAT3 and Wnt signaling pathways, but also reducing the efficacy of cancer-specific immunity against tumor cells. Accordingly, targeting the chronic inflammatory status in breast tissue has become a promising strategy for breast cancer therapy. Recently, due to the annoying side effects accompanying by traditionally anticancer drugs, there is an increased interest in finding out natural sources to treat BC. Herein, we report that antroquinonol (AQ) and/or 4-acetylantroquinonol B (4-AAQB) isolated from Antrodia Camphorata were able to modulate the expression of several inflammatory mediators, IL-6 and IFN-γ in particular, and downregulate the aromatase expression and Wnt signaling responses induced by inflammatory status. Taken together, the present findings provide new insights into the role of AQ and 4-AAQB in inflammatory breast tumors and also suggest them as promising candidates for breast cancer immunotherapy.

description: The local food movement is rapidly evolving in Hungary. Three market types can be identified: traditional, farmers’ and organic markets. Results show that farmer- and farmspecific characteristics as well as attitudes greatly and variously influence the decision of small-scale farmers on finding the proper market type. A relatively young, educated and innovative farmer group is interested mostly in selling at farmers’ markets. The outcomes are important in the light of the coming EU funding schemes as small-scale farmers using different marketing channels may require targeted supporting frameworks and solutions.
Mid-Pliocene to Early Pleistocene Sea Surface and Land Temperature History of NW Australia Based on Organic Geochemical Proxies from Site U1463
Creators: name: Smith, Rebecca
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Ocean gateways facilitate water circulation between ocean basins, and therefore directly impact thermohaline circulation and global climate. In order to better predict the effects of future climate change, it is critical to constrain past changes in ocean gateway behavior, and corresponding changes in thermohaline circulation, particularly during analogue periods for modern climate change. The Indonesian Throughflow (ITF) is a primary ocean gateway and vital component of the global conveyor that transports water from the Pacific Ocean into the Indian Ocean, however due to a lack of long and continuous sedimentary records from locations under its influence, changes in ITF behavior remain poorly constrained. In this study organic geochemical biomarkers preserved in marine sediments are used to reconstruct both sea surface and continental air temperatures in Northwest (NW) Australia from sediments spanning the mid-Pliocene Warm Period (mPWP), a critical carbon dioxide (CO2) and temperature analogue period for modern climate change spanning 3.3-3.0 Ma. These sediments were collected during IODP Expedition 356 from Site U1463, located near the outlet of the ITF, and are therefore sensitive to changes in ITF behavior over time. Here, NW Australian air temperatures were reconstructed from 1.5-3.5 Ma using the MBT’5ME proxy (Weijers et al., 2007a; De Jonge et al., 2014a), and offshore sea surface temperatures (SSTs) were reconstructed using both the TEX86 proxy (Schouten et al., 2002; Tierney & Tingley, 2014) and the Long Chain Diol Index (LDI; Rampen et al., 2012). Global climate events, including Marine Isotope Stages (MIS) 55, 63, 64, 82, 84, 88, 92, G10, G18, G20, G22, and M2 (Lisiecki & Raymo, 2005) are apparent in all of our records. TEX86 SSTs suggest a stronger cooling signal during MIS Stages G18, G20 and G22 relative to cooling during MIS M2, however LDI SSTs do not yield the same result. Overall, all three proxies indicate higher temperatures across the Pliocene and a cooling trend from ~1.7-1.5 Ma. Cooling occurs during an arid interval identified by Christensen et al. (2017), from 2.4-1.0 Ma, which suggests that offshore cooling contributed to shifts in NW Australian continental hydrology. Cooling from 3.5-1.5 Ma at Site U1463 was likely a reflection of 1) constriction of the ITF from 5-2 Ma and a switch from warm South Pacific to cool North Pacific source waters, and 2) an increase in meridional SST gradients at 1.8 Ma; the particularly strong cooling signal identified in all three records at 1.7 Ma is likely a direct response to the latter. This study helps elucidate ITF variability and shifts in thermohaline circulation across the Plio-Pleistocene and the mPWP, which will help modelers better predict the effects of future climate change.

description: We present an approach that pursues an adequate representation of product transformation possibilities for a technology generating, in addition to marketed (good) products, some environmentally detrimental non-marketed byproducts (bad outputs). As the shadow price of a non-marketed output depends on its marginal transformation rates with marketed outputs, representation of technological relationships between different groups of outputs deserves a particular attention. We model the technology by using two functions: an input distance function describing technically feasible input-output combinations, and a hedonic output function capturing relationships among good and bad outputs. This procedure offers more appropriate consideration and modeling of the interactions between different groups of outputs. An empirical application of the approach to the case of Dutch dairy farms1 demonstrates the complexity of interactions between outputs and the value of more elaborate representations of production possibilities. The analysis indicates that nitrogen surplus abatement costs vary widely among Dutch dairy farms and that these costs have increased substantially over time.

description: This study examines the effects of varying cross girder spacing in T-girder bridges using finite element analysis with Midas Civil and CSiBridge. Midas Civil utilized grillage modeling, while CSiBridge employed shell modeling. We validated the finite element model results against manual analysis. A 25 m span RCC T-girder bridge with three longitudinal main girders, constant slab and girder thickness, and uniform material properties was selected. We created different models by varying the number of cross girders from 0 to 10 and analyzed their impact on key structural parameters, including shear force, maximum displacement, bending moment, and torsion.

description: This paper provides a quantitative assessment of the effects of input and output prices on French GHG emissions from agriculture, forestry and other land use (AFOLU) at the NUTS2 level. Reduced-form, random-effect spatial error models are estimated for four emissions categories (nitrogen use, manure management, enteric fermentation, and land use, land-use change and forestry) in order to account for both spatial autocorrelation and spatial unobserved heterogeneity. The main findings are: (i) price impacts on emission levels are found to be significant, although sign and magnitude vary from one emission category to the other, (ii) estimated price effects are more apparent when emission categories are analyzed separately rather than aggregated, and (iii) the spatial dimension is found to play an important role. The estimated models are then used to simulate the effects of a doubling of crop prices on AFOLU emissions. The results indicate that this would lead to an 11%-increase in agricultural sources.

description: This paper investigates the effect of nearby nature substitutes on preferences for nature restoration. Previous studies have generally approached the substitution question by looking into competing destinations. We evaluate substitutes from the respondent’s viewpoint. We use a contextual approach relying on densities of nature substitutes within various ranges from each respondent’s home. This approach has the advantage of allowing the consideration of the direct, indirect and non-use values of nature. Data from three similar discrete choice experiments carried out in Flanders (northern Belgium) are compared. Different spatial discounting factors are tested to better understand how the substitution effect behaves with regard to distance. Latent class analyses are performed to account for preference heterogeneity among respondents. Our results show divergent behaviours across groups of respondents. The “distance-to-substitutes” affects the way respondents rank substitutes and we observe a significant influence of the squared average buffer distance. However, this effect varies in sign across case studies and classes of respondents. Our research calls for further investigation of the influence of taste heterogeneity and nature perception on people’s capacity to value nature. The eligibility of potential nature substitutes and what contributes to their relative attractiveness compared to other substitutes, deserve further exploration in future research.

description: We calculate the complete one-loop effective potential for SU(2) gauge bosons at temperature T as a function of two variables: phi, the angle associated with a non-trivial Polyakov loop, and H, a constant background chromomagnetic field. Using techniques broadly applicable to finite temperature field theories, we develop both low and high temperature expansions. At low temperatures, the real part of the effective potential V_R indicates a rich phase structure, with a discontinuous alternation between confined (phi=pi) and deconfined phases (phi=0). The background field H moves slowly upward from its zero-temperature value as T increases, in such a way that sqrt(gH)/(pi T) is approximately an integer. Beyond a certain temperature on the order of sqrt(gH), the deconfined phase is always preferred. At high temperatures, where asymptotic freedom applies, the deconfined phase phi=0 is always preferred, and sqrt(gH) is of order g^2(T)T. The imaginary part of the effective potential is non-zero at the global minimum of V_R for all temperatures. A non-perturbative magnetic screening mass of the form M_m = cg^2(T)T with a sufficiently large coefficient c removes this instability at high temperature, leading to a stable high-temperature phase with phi=0 and H=0, characteristic of a weakly-interacting gas of gauge particles. The value of M_m obtained is comparable with lattice estimates.

description: The unambiguous observation of a Chiral Magnetic Effect (CME)-driven charge separation is the core aim of the isobar program at RHIC consisting of ${^{96}_{40}}$Zr+${^{96}_{40}}$Zr and ${^{96}_{44}}$Ru+${^{96}_{44}}$Ru collisions at $\sqrt {s_{\rm NN}}\!=\!200$ GeV. We quantify the role of the spatial distributions of the nucleons in the isobars on both eccentricity and magnetic field strength within a relativistic hadronic transport approach (SMASH, Simulating Many Accelerated Strongly-interacting Hadrons). In particular, we introduce isospin-dependent nucleon-nucleon spatial correlations in the geometric description of both nuclei, deformation for ${^{96}_{44}}$Ru and the so-called neutron skin effect for the neutron-rich isobar i.e. ${^{96}_{40}}$Zr. The main result of this study is a reduction of the magnetic field strength difference between ${^{96}_{44}}$Ru+${^{96}_{44}}$Ru and ${^{96}_{40}}$Zr+${^{96}_{40}}$Zr by a factor of 2, from $10\%$ to $5\%$ in peripheral collisions when the neutron-skin effect is included. Further, we find an increase of eccentricity by up to 10$\%$ when deformation is taken into account while neither the neutron skin effect nor the nucleon-nucleon correlations result into a significant modification of this observable with respect to the traditional Woods-Saxon modeling. Our results suggest a significantly smaller CME signal to background ratio for the experimental charge separation measurement in peripheral collisions with the isobar systems than previously expected.

description: Fusarium spp. are able to cause a wide range of opportunistic infections in both immunocompromised and immunocompetent individuals. Thus, new therapeutic options should be considered. We evaluated the antifungal activity of three phytocompounds (cinnamaldehyde, CIN; carvacrol, CRV; and thymol, THY), as well as their activities when combined with amphotericin B (AMB), caspofungin (CAS), itraconazole (ITC) and voriconazole (VRC) against 20 clinical isolates of Fusarium. Broth microdilution (M38-A2) and checkerboard methodologies were used to obtain MICs (Minimum inhibitory concentration) and FICIs (Fractional Inhibitory Concentration Index), respectively. The MICs observed for the phytocompounds were: 20–80 for CIN, 40-> 320 for CRV and 40–320 µg/mL for THY. The most effective combinations (synergism rates) were: THY + CAS (96%), CRV + CAS (88%), THY + AMB (76%), CRV + AMB (68%), THY + VRC (68%) and CRV + VRC (60%). Our findings suggest that CRV and THY have potent activity when combined with CAS, AMB or VRC.

In the common market the competitiveness of products and producers is a key factor. One important factor of competitiveness is labour productivity, which can be divided into partial factors that could be the technical equipment and the productivity of those tools. The study examines the changes of these two partial productivity factors at the former EU member and at the group of countries integrated in 2004.

description: We construct and propose the "Bayesian Validation Metric" (BVM) as a general model validation and testing tool. We find the BVM to be capable of representing all of the standard validation metrics (square error, reliability, probability of agreement, frequentist, area, probability density comparison, statistical hypothesis testing, and Bayesian model testing) as special cases and find that it can be used to improve, generalize, or further quantify their uncertainties. Thus, the BVM allows us to assess the similarities and differences between existing validation metrics in a new light. The BVM has the capacity to allow users to invent and select models according to novel validation requirements. We formulate and test a few novel compound validation metrics that improve upon other validation metrics in the literature. Further, we construct the BVM Ratio for the purpose of quantifying model selection under user defined definitions of agreement in the presence or absence of uncertainty. This construction generalizes the Bayesian model testing framework.

description: In a recent publication we have calculated elastic charmonium production in ep collisions employing realistic charmonia wave functions and dipole cross sections and have found good agreement with the data in a wide range of s and Q^2. Using the ingredients from those calculations we calculate exclusive electroproduction of charmonia off nuclei. Here new effects become important, (i) color filtering of the c-cbar pair on its trajectory through nuclear matter, (ii) dependence on the finite lifetime of the c-cbar fluctuation (coherence length) and (iii) gluon shadowing in a nucleus compared to the one in a nucleon. Total coherent and incoherent cross sections for C, Cu and Pb as functions of s and Q^2 are presented together with some differential cross sections. The results can be tested with future electron-nucleus colliders or in peripheral collisions of ultrarelativistic heavy ions.

FERONIA-RELATED RECEPTOR KINASE 7 AND FERONIA AND THEIR ROLE IN RECEIVING AND TRANSDUCING SIGNALS
Creators: name: vyshedsky, David
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Receptor kinases (RKs) are transmembrane proteins that have been shown to regulate an array of important processes in A. thaliana, including polar cell growth, plant reproduction, and many other plant growth processes. In this thesis, I examine RECEPTOR KINASE 7 (RK7) and FERONIA (FER), two closely related transmembrane RKs, and their effects on plant reproduction. The RK7 gene when knocked out (rk7) in conjunction with FER resulted in delayed plant growth, decreased seed yield, and a lower percentage of the seeds germinating as compared to the single FER knockout. Transgenic plants with GUS reporter driven by RK7 promoter and RK7 promoter expressed GFP-tagged RK7 (RK7-GFP) were generated to study, respectively, the expression property of the RK7 gene and characterize the location of the RK7 protein. RK7 expression increased in the papillary cells as a direct result of pollination. Transgenic plants with RK7-GFP showed that RK7 protein localizes to the plasma membrane of stigma cells and pollination induces prominent internalization of this protein. RK7 is also expressed during seedling growth. rk7 mutant seedlings had a much weaker physiological response to brassinosteroids than wild type plants, implicating an involvement of RK7 in brassinosteroid signaling. Taken together this data point to the importance of RK7 in plant growth and reproduction through its ability to receive and transduce signals.

description: The organization on a regional basis of the public Italian Agricultural Advisory Services (AAS) responds both to historical reasons and to the extreme differentiation of the local farming systems, institutional arrangements, and many other contextual factors. In Italy, each Region has its own law and its own policy on AAS, developing 21different systems with a poor coordination and great regional variety. The main aim of this paper is to explore the dimension of transparency and accountability of decentralization, considering the ASS governance and the coordination structures. The analysis integrates a literature review with empirical researches conducted through in-depth interviews.

The results indicate that the producer price of beef and the consumer price of beef roast are co-integrated and that price transmission is quite effective. Liquid milk does not significantly differ from raw milk. However, the consumer price of liquid milk and the producer price of milk do not follow each other.

description: Innovations in Field Programmable Gate Array (FPGA) manufacturing processes and architectural design have led to the development of extremely large FPGAs. There has also been a widespread adaptation of these large FPGAs in cloud infrastructures and data centers to accelerate search and machine learning applications. Two important topics related to FPGAs are addressed in this work: on-chip communication and security. On-chip communication is quickly becoming a bottleneck in to- day’s large multi-million gate FPGAs. Hard Networks-on-Chip (NoC), made of fixed silicon, have been shown to provide low power, high speed, flexible on-chip communication. An iterative algorithm for routing pre-scheduled time-division-multiplexed paths in a hybrid NoC FPGA architecture is demonstrated in this thesis work. The routing algorithm is based on the well known Pathfinder algorithm, overcomes several limitations of a previous greedy implementation and successfully routes connections
using a higher number of timeslots than greedy approaches. The new algorithm shows an average bandwidth improvement of 11% for unicast traffic and multicast traffic patterns. Regarding on-chip FPGA security, a recent study on covert channel communication in Xilinx FPGA devices has shown information leaking from long interconnect wires into immediate neighboring wires. This information leakage can be used by an attacker in a multi-tenant FPGA cloud infrastructure to non-invasively steal secret information from an unsuspecting user design. It is demonstrated that the information leakage is also present in Intel SRAM FPGAs. Information leakage in Cyclone-IV E and Stratix-V FPGA devices is quantified and characterized with varying parameters, and across different routing elements of the FPGAs.

description: We introduce an algebro-geometrically motived integration-by-parts (IBP) reduction method for multi-loop and multi-scale Feynman integrals, using a framework for massively parallel computations in computer algebra. This framework combines the computer algebra system Singular with the workflow management system GPI-Space, which is being developed at the Fraunhofer Institute for Industrial Mathematics (ITWM). In our approach, the IBP relations are first trimmed by modern algebraic geometry tools and then solved by sparse linear algebra and our new interpolation methods. These steps are efficiently automatized and automatically parallelized by modeling the algorithm in GPI-Space using the language of Petri-nets. We demonstrate the potential of our method at the nontrivial example of reducing two-loop five-point nonplanar double-pentagon integrals. We also use GPI-Space to convert the basis of IBP reductions, and discuss the possible simplification of IBP coefficients in a uniformly transcendental basis.

description: Introduction: The Professionalism of Medical Students (PoMS) study aimed to develop a comprehensive understanding of Australian and New Zealand (Aus/NZ) medical students’ opinions and experience with professionalism dilemmas. Methods: A confidential, online survey for medical students was developed and distributed to all Aus/NZ medical schools. Students submitted de-identified demographic information, gave opinions on the acceptability of a range of student behaviours for professionally challenging situations, and whether they had encountered similar situations. Results: 3171 medical students participated from all 21 Aus/NZ medical schools (16% of the total student population). Medical students reported encountering many of the professionally challenging situations and had varying opinions on what was acceptable behaviour for the scenarios. In general, students’ opinions were not influenced by the seniority, gender or the type of health professional involved in the scenario. Participant demographic factors appeared to have significant effects on professional opinions – particularly male gender and being a student in the latter stages of the course. Discussion: Medical students’ professional opinions are a complex area. The PoMS data provides a reference point for students, their educators and other health professionals in identifying current student professional behaviour norms, determining the effects of demographic factors on their decision making, and where important gaps exist in medical students’ approaches to professionalism.
The study of a flavor-changing neutral toppion production process $e^+e^-\to t\bar{c}Π_t^0$

description: We have studied a flavor-changing toppion production process $e^{+}e^{-}\to t\bar{c}Π^{0}_{t}$ in the topcolor-assisted technicolor(TC2) model. The studies show that, with high centre of mass energy in TESLA collider, the production cross section of $e^{+}e^{-}\to t\bar{c}Π^{0}_{t}$ is at the order of magnitude 0.1 fb in most parameter regions of TC2 model and a few tens events of toppion can be produced each year. The resonance effect can enhance the cross section to a few fb when toppion mass is small. With clean background, the toppion events can possibly be detected at TESLA collider. On the other hand, we find that there exists a narrow peak near $m_t-m_c$ in the toppion-charm invariant mass distribution which could be clearly detected. Therefore, such a toppion production process $e^{+}e^{-}\to t\bar{c}Π^{0}_{t}$ provides a unique chance to detect toppion events and test the TC2 model.

description: Water is an essential natural resource for sustainable development due to its importance. Access to this resource and adequate sanitation is a daily struggle in developing countries it is therefore necessary to know its state and ameliorate its quality. This study is a contribution to a better qualitative understanding of groundwater in the Far North, particularly in the localities of Mambang, Kodjeleo and Mogordom. The methodological approach consisted of field investigations, measurements of physico-chemical parameters in situ and laboratory work. The processed data was analyzed using statistical methods, classical and numerical methods based on the determination of the water quality index and the natural background level.The results obtained showed that the waters of the study area tended towards neutrality (6.98 ≤ pH ≤ 7.34), with average to excellent mineralization (571≤ EC ≤1038). Three main facies types were identified with the water type dominating the study area Calcium, Magnesium, Sulphate (66.67%). This multiplicity of facies suggests that there are several factors that control water quality in these localities. The water quality index shows that the waters are of poor quality (66.67%) and the values of the geochemical natural background level are: Ammonium ions 0.16mg/l; Chlorine 46.67mg/l; Cadmium 0.00038 mg/l; Lead 0.00065mg./l and Fluoride 0.27mg/l respectively. Although the number of samples is limited, this study provides the elements for better local water management and regulation based on the values of the natural background level and threshold in this part of the Far North of Cameroon.

description: In the paper we present applications of a qualitative multi-attribute modelling method DEX for decision support about the introduction and use of geneticallymodified organisms (GMO) for food and feed. In three 5th and 6th Framework Programme European projects, we have developed a number of models, of which we present three: the »Grignon« model for the assessment of ecological and economic impacts of GMO, ESQI model for the assessment of soil quality, and SMAC model for the assessment of co-existence of conventional and GMO maize. We also mention a decision support system developed within the project Co-Extra. In the second part, we assess the achieved results and describe our lessons learned during the model development.
