Five-quark components in $Δ(1232)\to Nπ$ decay

description: Five-quark $qqqq\bar q$ components in the $Δ(1232)$ are shown to contribute significantly to $Δ(1232)\to Nπ$ decay through quark-antiquark annihilation transitions. These involve the overlap between the $qqq$ and $qqqq\bar q$ components and may be triggered by the confining interaction between the quarks. With a $\sim$ 10% admixture of five-quark components in the $Δ(1232)$ the decay width can be larger by factors 2 - 3 over that calculated in the quark model with 3 valence quarks, depending on the details of the confining interaction. The effect of transitions between the $qqqq\bar q$ components themselves on the calculated decay width is however small. The large contribution of the quark-antiquark annihilation transitions thus may compensate the underprediction of the width of the $Δ(1232)$ by the valence quark model, once the $Δ(1232)$ contains $qqqq\bar q$ components with $\sim$ 10% probability.

Bipartite entanglement in the spin-1/2 Ising-Heisenberg planar lattice constituted of identical trigonal bipyramidal plaquettes
Creators: name: Gálisová, Lucia

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The bipartite entanglement is rigorously examined in the spin-$1/2$ Ising-Heisenberg planar lattice composed of identical inter-connected bipyramidal plaquettes at zero and finite temperatures using the quantity called concurrence. It is shown that the Heisenberg spins of the same plaquette are twice stronger entangled in the two-fold degenerate quantum ground state than in the macroscopically degenerate quantum chiral one. The bipartite entanglement with chiral features completely disappears below or exactly at the critical temperature of the model, while that with no chirality may survive even above the critical temperature of the model. Non-monotonous temperature variations of the concurrence clearly evidence the activation of the entangled Heisenberg states also above classical ground state as well as their re-appearance above the critical temperature of the model.

description: We use deep, spatially resolved spectroscopy from the LEGA-C Survey to study radial variations in the stellar population of 17 spectroscopically-selected post-starburst (PSB) galaxies. We use spectral fitting to measure two Lick indices, $Hδ_A$ and $Fe4383$, and find that, on average, PSB galaxies have radially decreasing $Hδ_A$ and increasing $Fe4383$ profiles. In contrast, a control sample of quiescent, non-PSB galaxies in the same mass range shows outwardly increasing $Hδ_A$ and decreasing $Fe4383$. The observed gradients are weak ($\approx-0.2$ Å/$R_e$), mainly due to seeing convolution. A two-SSP model suggests intrinsic gradients are as strong as observed in local PSB galaxies ($\approx -0.8$ Å$/R_e$). We interpret these results in terms of inside-out growth (for the bulk of the quiescent population) vs star formation occurring last in the centre (for PSB galaxies). At $z\approx0.8$, central starbursts are often the result of gas-rich mergers, as evidenced by the high fraction of PSB galaxies with disturbed morphologies and tidal features (40%). Our results provide additional evidence for multiple paths to quiescence: a standard path, associated with inside-out disc formation and with gradually decreasing star-formation activity, without fundamental structural transformation, and a fast path, associated with centrally-concentrated starbursts, leaving an inverse age gradient and smaller half-light radius.

description: Weak gravitational lensing of background galaxies offers an excellent opportunity to study the intervening distribution of matter. While much attention to date has focused on the two-point function of the cosmic shear, the three-point function, the {\it bispectrum}, also contains very useful cosmological information. Here, we compute three corrections to the bispectrum which are nominally of the same order as the leading term. We show that the corrections are small, so they can be ignored when analyzing present surveys. However, they will eventually have to be included for accurate parameter estimates from future surveys.

description: We analyze the size and evolution of quantum fluctuations of cosmologically relevant geometric observables, in the context of the effective relational cosmological dynamics of GFT models of quantum gravity. We consider the fluctuations of the matter clock observables, to test the validity of the relational evolution picture itself. Next, we compute quantum fluctuations of the universe volume and of other operators characterizing its evolution (number operator for the fundamental GFT quanta, effective Hamiltonian and scalar field momentum). In particular, we focus on the late (clock) time regime, where the dynamics is compatible with a flat FRW universe, and on the very early phase near the quantum bounce produced by the fundamental quantum gravity dynamics.

description: We report the discovery of up to 35 new supernova remnants (SNRs) from a 42 arcsec resolution 90cm multi-configuration Very Large Array survey of the Galactic plane covering 4.5 deg< l <22.0 deg and |b| < 1.25 deg. Archival 20cm, 11cm, and 8 micron data have also been used to identify the SNRs and constrain their properties. The 90cm image is sensitive to SNRs with diameters 2.5 arcmin to 50 arcmin and down to a surface brightness limit of about 10^{-21} W m^{-2} Hz^{-1} sr^{-1}. This survey has nearly tripled the number of SNRs known in this part of the Galaxy, and represents an overall 15% increase in the total number of Galactic SNRs. These results suggest that further deep low frequency surveys of the inner Galaxy will solve the discrepancy between the expected number of Galactic SNRs and the significantly smaller number of currently known SNRs.

description: The finite temperature behavior of small Silicon (Si$_{10}$, Si$_{15}$, and Si$_{20}$) and Tin (Sn$_{10}$ and Sn$_{20}$) clusters is studied using isokinetic Born-Oppenheimer molecular dynamics. The lowest equilibrium structures of all the clusters are built upon a highly stable tricapped trigonal prism unit which is seen to play a crucial role in the finite temperature behavior of these clusters. Thermodynamics of small tin clusters (Sn$_{10}$ and Sn$_{20}$) is revisited in light of the recent experiments on tin clusters of sizes 18-21 [G. A. Breaux et. al. Phys. Rev. B {\bf 71} 073410 (2005)]. We have calculated heat capacities using multiple histogram technique for Si$_{10}$, Sn$_{10}$ and Si$_{15}$ clusters. Our calculated specific heat curves have a main peak around 2300 K and 2200 K for Si$_{10}$ and Sn$_{10}$ clusters respectively. However, various other melting indicators such as root mean square bond length fluctuations, mean square displacements show that diffusive motion of atoms within the cluster begins around 650 K. The finite temperature behavior of Si$_{10}$ and Sn$_{10}$ is dominated by isomerization and it is rather difficult to discern the temperature range for transition region. On the other hand, Si$_{15}$ does show a liquid like behavior over a short temperature range followed by the fragmentation observed around 1800 K. Finite temperature behavior of Si$_{20}$ and Sn$_{20}$ show that these clusters do not melt but fragment around 1200 K and 650 K respectively.

description: In this study we present results of the chemical composition of the moraine cover from the Inylchek Glacier in Kyrgyzstan using observations from three field campaigns between 2010 and 2012. The sample locations were selected based on high-resolution remote sensing data. Sampling included the main profile from Lake Merzbacher to Station “Hochgebirgsobservatorium Gottfried Merzbacher”, which is about 8 km in length trending in N-S-direction. Chemical analyses of more than 60 elements, including Rare Earth Elements (an important tool for the discrimination and localisation of source areas of sediments, boulders and outcropping rocks) were carried out. Based on these data different geochemical material streams have been identified. Generally, two chemical groups of sediments, the North Type/Lake Merzbacher and the South Type/Southern Inylchek can be distinguished. The Lake Merzbacher Type sediments are characterised by a uniform chemical composition, whereas the South Inylchek Type is geochemically more heterogeneous. Toxic elements in the sediments, such as Ni, As, Cd, Tl and U, are moderately enriched. The low sulphur concentration suggests that the main water transport is caused by suspended matter. One erratic granite block was analysed for in situ cosmogenic 10Be for exposure age dating. The age of 330 ±90 a is conform to a glacier high stand during the “Maunder“ minimum of the solar activity.

description: We have identified seven ultraluminous X-ray sources (ULXs) which are coincident with globular cluster candidates (GCs) associated with M87. ULXs in the old GC environment represent a new population of ULXs, and ones likely to be black holes. In this study we perform detailed X-ray spectroscopic followup to seven GC ULXs across a wealth of archival Chandra observations and long time baseline of 16 years. This study brings the total known sample of GC ULXs to 17. Two of these sources show variability in their X-ray luminosity of an order of magnitude over many years, and one of these sources shows intra-observational variability on the scale of hours. While the X-ray spectra of the majority of globular cluster ULXs are best fit by single component models, one of the sources studied in this paper is the second GC ULX to be best fit by a two component model. We compare this new sample of GC ULXs to the previously studied sample, and compare the X-ray and optical properties counterparts across the samples. We find that the clusters that host ULXs in M87 have metallicities from g-z=1.01 to g-z=1.70. The best-fit power-law indices of the X-ray spectra range from Gamma=1.37-2.21, and the best fit inner black-body disk temperatures range from kT=0.56-1.90 keV.

First-principles quantum dynamics in interacting Bose gases II: stochastic gauges

description: First principles simulations of the quantum dynamics of interacting Bose gases using the stochastic gauge representation are analyzed. In a companion paper, we showed how the positive P representation can be applied to these problems using stochastic differential equations. That method, however, is limited by increased sampling error as time evolves. Here, we show how the sampling error can be greatly reduced and the simulation time significantly extended using stochastic gauges. In particular, local stochastic gauges (a subset) are investigated. Improvements are confirmed in numerical calculations of single-, double-, and multi-mode systems in the weak mode coupling regime. Convergence issues are investigated, including the recognition of two modes by which stochastic equations produced by phase space methods in general can diverge: movable singularities and a noise-weight relationship. The example calculated here displays wave-like behaviour in spatial correlation functions propagating in a uniform 1D gas after a sudden change in the coupling constant.This could in principle be tested experimentally using Feshbach resonance methods.

Intracellular calcium changes in a hybrid mouse dorsel root ganglion (DRG) neuronal cell line MD3 following [gamma]-aminobutyric acid (GABA) receptor activation
Creators: name: Yokogawa, Tomonori
Publisher: name: University of British Columbia

description: Application of y-aminobutyric acid (GABA) to dorsal root ganglion (DRG) neurons in vivo increases their membrane conductance for Cl⁻. I studied a mouse DRG neuronal cell line MD3, produced from hybridization between mouse (Balb/C) DRG neurons and N18TG2 neuroblastoma cells, for sensory and pharmacological properties. Immunostaining with markers for neurofilaments demonstrated the cells had neuronal characteristics. In addition, the hybrid cells reacted to CAP and ATP, similar to sensory neurons. Then, I investigated the mechanism and effects of externally applied agonists and antagonists of GABA on MD3 cells in vitro. I used fura-2 to monitor GABA-evoked depolarizations in terms of intracellular Ca²⁺, [Ca²⁺][sub i]. Application of GABA to hybrid cells caused [Ca²⁺i increases that implied GABA[sub A] receptor (GABA[sub A]R) activation. Applications of GABA[sub A]R antagonists bicuculline (BIC) and picrotoxinin (PTX) confirmed the GABA[sub A]R involvement in the intracellular response. BIC, but not PTX, blocked the GAB A-mediated elevations in [Ca²⁺i. ZAP A, a potent agonist of low affinity GABAARs, also increased [Ca²⁺i in hybrid cells. The GABA-evoked increases in [Ca²⁺i were not apparent during the absence of Ca²⁺ in the extracellular environment and exposure to dihydropyridines (DHP) nimodipine and nifedipine. The results imply that depolarization-activated Ca²⁺ influx increased [Ca²⁺i during GABA application. I also studied the effects of GABA[sub B] receptor (GABA[sub B]R) agonist, p-parachlorophenyl-y-aminobutyric acid (baclofen), on the hybrid cells. Detectable changes in the [Ca2+]j were not apparent during GABA[sub B]R activation alone. 2-hydroxy sac lo fen blocked the inhibitory effect of baclofen and antagonized the GABA[sub B]R. The MD3 hybrid cell line possesses GABA[sub A] and GABA[sub B]R[sub S]. The augmentation in [Ca²⁺j occurred when GABA activated the GABA[sub A]R, increasing Cl⁻ conductance and depolarizing the membrane potential, thus resulting Ca²⁺ influx through voltage-dependent Ca²⁺ channels that increase intracellular Ca²⁺. The source of the elevations in [Ca²⁺][sub i] was the extracellular environment. Nifedipine and nimodipine inhibited the GABA-induced transmembrane influx of Ca²⁺ through VGCCs. Activation of GABA[sub B]Rs with baclofen attenuated the depolarization-induced increases in [Ca²⁺][sub i]. In addition, baclofen influenced L - type channels since DHPs inhibited the K⁺-mediated [Ca²⁺][sub i] elevations. The MD3 cells exhibited similarities to its sensory parent. Nevertheless, it is a useful model system for the examination of GABA and other drug effects.

description: We propose OneFlow - a flow-based one-class classifier for anomaly (outlier) detection that finds a minimal volume bounding region. Contrary to density-based methods, OneFlow is constructed in such a way that its result typically does not depend on the structure of outliers. This is caused by the fact that during training the gradient of the cost function is propagated only over the points located near to the decision boundary (behavior similar to the support vectors in SVM). The combination of flow models and a Bernstein quantile estimator allows OneFlow to find a parametric form of bounding region, which can be useful in various applications including describing shapes from 3D point clouds. Experiments show that the proposed model outperforms related methods on real-world anomaly detection problems.

description: In large-scale networks of uncertain dynamical systems, where communication is limited and there is a strong interaction among subsystems, learning local models and control policies offers great potential for designing high-performance controllers. At the same time, the lack of safety guarantees, here considered in the form of constraint satisfaction, prevents the use of data-driven techniques to safety-critical distributed systems. This paper presents a safety framework that guarantees constraint satisfaction for uncertain distributed systems while learning. The framework considers linear systems with coupling in the dynamics and subject to bounded parametric uncertainty, and makes use of robust invariance to guarantee safety. In particular, a robust non-convex invariant set, given by the union of multiple ellipsoidal invariant sets, and a nonlinear backup control law, given by the combination of multiple stabilizing linear feedbacks, are computed offline. In presence of unsafe inputs, the safety framework applies the backup control law, preventing the system to violate the constraints. As the robust invariant set and the backup stabilizing controller are computed offline, the online operations reduce to simple function evaluations, which enables the use of the proposed framework on systems with limited computational resources. The capabilities of the safety framework are illustrated by three numerical examples.

description: We report the numerical calculations of the current-voltage characteristics of intrinsic Josephson junctions in high- superconductors. The charging effect at superconducting layers is taken into account. A set of equations is used to study the non-linear dynamics of the system. In framework of capacitively coupled Josephson junctions model we obtain the total number of branches using fixed initial conditions for phases and their derivatives. The influence of the coupling constant αon the current-voltage characteristics at fixed parameter β(β^2=1/β_c, where β_c is McCumber parameter) and the influence of αon β-dependence of the current-voltage characteristics are investigated. We obtain the α-dependence of the branch's slopes and branch's endpoints. The obtained results show new features of the coupling effect on the scheme of hysteresis jumps in current-voltage characteristics of intrinsic Josephson junctions.

description: Meromorphic connections on Riemann surfaces originate and are closely related to the classical theory of linear ordinary differential equations with meromorphic coefficients. Limiting behaviour of geodesics of such connections has been studied by e.g. Abate, Bianchi and Tovena in relation with generalized Poincaré-Bendixson theorems. At present, it seems still to be unknown whether some of the theoretically possible asymptotic behaviours of such geodesics really exist. In order to fill the gap, we use the branched affine structure induced by a Fuchsian meromorphic connection to present several examples with geodesics having infinitely many self-intersections and quite peculiar omega-limit sets.

description: We study gravitational solutions that admit a dual CFT description and carry non zero dipole charge. We focus on the black ring solution in AdS_3 x S^3 and extract from it the one-point functions of all CFT operators dual to scalar excitations of the six-dimensional metric. In the case of small black rings, characterized by the level N, angular momentum J and dipole charge q_3, we show how the large N and J dependence of the one-point functions can be reproduced, under certain assumptions, directly from a suitable ensemble in the dual CFT. Finally we present a simple toy model that describes the thermodynamics of the small black ring for arbitrary values of the dipole charge.

description: We study the spectrum of the scalar Laplacian on the five-dimensional toric Sasaki-Einstein manifolds Y^{p,q}. The eigenvalue equation reduces to Heun's equation, which is a Fuchsian equation with four regular singularities. We show that the ground states, which are given by constant solutions of Heun's equation, are identified with BPS states corresponding to the chiral primary operators in the dual quiver gauge theories. The excited states correspond to non-trivial solutions of Heun's equation. It is shown that these reduce to polynomial solutions in the near BPS limit.

Interaction between temperature and oxygen helps define fish biogeography

Publisher: name: No Publisher Supplied
Year: 2021

description: Global climate change has had a substantial impact on marine biogeography and many species have experienced large spatial redistributions. While many approaches to understanding these changes focus on thermal habitat, theory from physiology and ecology suggest that oxygen and prey should also be important constraints on species distributions and important drivers of changing distributions. Here, we test whether oxygen, a measure of temperature-induced hypoxia (the Metabolic Index), and prey availability improve our ability to explain historical shifts in the distribution of Black Sea Bass (Centropristis striata). Estimates of prey availability and oxygen were calculated from a regional oceanographic hindcast. The best performing model included the Metabolic Index, demonstrating how correlative approaches for species habitat modeling can be strengthened by including variables with mechanistic links to physiology. To better understand species on the move in the ocean, we encourage further efforts to measure, model, and interpolate oxygen availability, as well as the development of methods to extrapolate temperature-dependent hypoxia across a wider range of species.

description: We present a novel Machine Learning (ML) based strategy to search for binary black hole (BBH) mergers in data from ground-based gravitational wave (GW) observatories. This is the first ML-based search that not only recovers all the compact binary coalescences (CBCs) in the first GW transients catalog (GWTC-1), but also makes a clean detection of GW151216 by only adding a new coincident ranking statistic (MLStat) to a standard analysis that was used for GWTC-1. In CBC searches, reducing contamination by terrestrial and instrumental transients, which create a loud noise background by triggering numerous false alarms, is crucial to improving the sensitivity for detecting true events. The sheer volume of data and a large number of expected detections also prompts the use of ML techniques. We perform transfer learning to train "InceptionV3", a pre-trained deep neural network, along with curriculum learning to distinguish GW signals from noisy events by analysing their continuous wavelet transform (CWT) maps. MLStat incorporates information from this ML classifier into the coincident search likelihood used by the standard PyCBC search. This leads to at least an order of magnitude improvement in the inverse false-alarm-rate (IFAR) for the previously "low significance" events GW151012, GW170729 and GW151216. We also perform the parameter estimation of GW151216 using SEOBNRv4HM_ROM. We carry out an injection study to show that MLStat brings substantial improvement to the detection sensitivity of Advanced LIGO for all compact binary coalescences. The average improvement in the sensitive volume is ~10% for low chirp masses (0.8-5 Msun), and ~30% for higher masses (5-50 Msun). This work demonstrates the immense potential and readiness of MLStat for finding new sources in current data and the possibility of its adaptation in similar searches.

description: Micro-expression has emerged as a promising modality in affective computing due to its high objectivity in emotion detection. Despite the higher recognition accuracy provided by the deep learning models, there are still significant scope for improvements in micro-expression recognition techniques. The presence of micro-expressions in small-local regions of the face, as well as the limited size of available databases, continue to limit the accuracy in recognizing micro-expressions. In this work, we propose a facial micro-expression recognition model using 3D residual attention network named MERANet to tackle such challenges. The proposed model takes advantage of spatial-temporal attention and channel attention together, to learn deeper fine-grained subtle features for classification of emotions. Further, the proposed model encompasses both spatial and temporal information simultaneously using the 3D kernels and residual connections. Moreover, the channel features and spatio-temporal features are re-calibrated using the channel and spatio-temporal attentions, respectively in each residual module. Our attention mechanism enables the model to learn to focus on different facial areas of interest. The experiments are conducted on benchmark facial micro-expression datasets. A superior performance is observed as compared to the state-of-the-art for facial micro-expression recognition on benchmark data.

The Johnson homomorphism and the second cohomology of IA_n

description: Let F_n be the free group on n generators. Define IA_n to be group of automorphisms of F_n that act trivially on first homology. The Johnson homomorphism in this setting is a map from IA_n to its abelianization. The first goal of this paper is to determine how much this map contributes to the second rational cohomology of IA_n. A descending central series of IA_n is given by the subgroups K_n^(i) which act trivially on F_n/F_n^(i+1), the free rank n, degree i nilpotent group. It is a conjecture of Andreadakis that K_n^(i) is equal to the lower central series of IA_n; indeed K_n^(2) is known to be the commutator subgroup of IA_n. We prove that the quotient group K_n^(3)/IA_n^(3) is finite for all n and trivial for n=3. We also compute the rank of K_n^(2)/K_n^(3).

Coloring linear hypergraphs: the Erdős-Faber-Lovász conjecture and the Combinatorial Nullstellensatz

Subjects: subject: Combinatorics (math.CO)

description: The long-standing Erdős-Faber-Lovász conjecture states that every $n$-uniform linear hypergaph with $n$ edges has a proper vertex-coloring using $n$ colors. In this paper we propose an algebraic framework to the problem and formulate a corresponding stronger conjecture. Using the Combinatorial Nullstellensatz, we reduce the Erdős-Faber-Lovász conjecture to the existence of non-zero coefficients in certain polynomials. These coefficients are in turn related to the number of orientations with prescribed in-degree sequences of some auxiliary graphs. We prove the existence of certain orientations, which verifies a necessary condition for our algebraic approach to work.

description: It has been recently pointed out [V. Giovanetti, S. Lloyd, and L. Maccone, Europhys. Lett., {\bf 62} pp. 615-621 (2003)] that, for certain classes of states, quantum entanglement enhances the "speed" of evolution of composite quantum systems, as measured by the time a given initial state requires to evolve to an orthogonal state. We provide here a systematic study of this effect for pure states of bipartite systems of low dimensionality, considering both distinguishable (two-qubits) subsystems, and systems constituted of two indistinguishable particles.

Thinking girls on-line : texts, body politics, and tamponed cyborgs
Creators: name: Zumsteg, Beatrix
Publisher: name: University of British Columbia

description: In affluent western societies, digital communication and information technologies increasingly reshape our social relations and identities, the way we perceive our selves and others. Given that we are all communicative and relational bodies in complex webs of power, the media of communication are central to the ways we are socially structured and relate to one another. The purpose of my thesis is to sketch a framework which can account critically for the dangers and benefits of embodying digital technologies while rethinking the gendered body politics of the everyday world. In this thesis, I develop a set of theoretical abstractions through which to think our bodies. With these theories, I paint images of modern body politics and of the micro- and macro-politics of power over life in larger socio-historical processes. M y textual analysis of Tampax's TRoom (http://www.troom.com), a corporate website exemplifies thinking these broader historical and social issues of embodiment. I focus on this website as a discursive frame that calls girls as free and subjugated subjects into digital texts of feminine protection. Thinking girl bodies through and against the 'civilizing' and disciplinary dimension of digital and sanitary technologies provides us with both liberating and confining images of what it may be like to be or become a girl. In the conclusion, I present the image of cyborgs, as hybrids of human organism and technology, to think our selves through everyday life techniques and technologies. Tamponed cyborgs provide realities that reformulate a bodily unity, capture contemporary issues of "girls" embodiment and incorporation of technology, and contribute to an understanding of the possibilities for discursive remappings of girls' social relations and selves.

description: We model the consumption life cycle of theater attendance for single movies by taking into account the size of the targeted group and the effect of social interactions. We provide an analytical solution of such model, which we contrast with empirical data from the film industry obtaining good agreement with the diverse types of behaviors empirically found. The model grants a quantitative measure of the valorization of this cul- tural good based on the relative values of the coupling between agents who have watched the movie and those who have not. This represents a measurement of the observed quality of the good that is extracted solely from its dynamics, independently of critics reviews.

Improving Simultaneous Translation by Incorporating Pseudo-References with Fewer Reorderings

description: Simultaneous translation is vastly different from full-sentence translation, in the sense that it starts translation before the source sentence ends, with only a few words delay. However, due to the lack of large-scale, high-quality simultaneous translation datasets, most such systems are still trained on conventional full-sentence bitexts. This is far from ideal for the simultaneous scenario due to the abundance of unnecessary long-distance reorderings in those bitexts. We propose a novel method that rewrites the target side of existing full-sentence corpora into simultaneous-style translation. Experiments on Zh->En and Ja->En simultaneous translation show substantial improvements (up to +2.7 BLEU) with the addition of these generated pseudo-references.

description: This paper examines the methodological problems to define a modelling approach to assess the impact of full or limited bilateral liberalisation of agricultural trade flows in the Euro-Mediterranean region. The bilateral trade liberalisation process in the region is framed by complexity, in policy instruments and in the characteristics of the products, in particular fruits and vegetables. Advantages and disadvantages of the general equilibrium and partial equilibrium approaches to simulate trade policy impacts are assessed. Caveats of existing models are related to the representation of specific policy instruments (tariffs, entry prices and other non-tariff measures) and on the seasonal nature of horticultural trade, which is of major importance in the Euro-Mediterranean Free Trade Are. The paper provides an illustration of how an imperfect substitute product model could be helpful to describe the trade effects of bilateral price changes, for given seasons.
