description: We show that the magnetic Raman response of a spin-liquid is independent of the polarizations of the light for triangular symmetries. In contrast, a ground-state that has a broken symmetry shows characteristic oscillations when the polarizations are rotated. This would allow to detect weak broken symmetries and emergent order-parameters. We focus on the Kagome antiferromagnet where no conventional long-range order has been found so far, and present the Raman cross-section of a spin-liquid and a valence bond crystal (VBC) using a random phase approximation.

description: The formation of gas giant planets is assumed to be preceded by the emergence of solid cores in the conventional sequential-accretion paradigm. This hypothesis implies that the presence of earth-like planets can be inferred from the detection of gas giants. A similar prediction cannot be made with the gravitational instability (hereafter GI) model which assumes that gas giants (hereafter giants) formed from the collapse of gas fragments analogous to their host stars. We propose an observational test for the determination of the dominant planet-formation channel. Based on the sequential-accretion (hereafter SA) model, we identify several potential avenues which may lead to the prolific formation of a population of close-in earth-mass ($M_\oplus$) planets (hereafter close-in earths) around stars with 1) short-period or 2) solitary eccentric giants and 3) systems which contain intermediate-period resonant giants. In contrast, these close-in earths are not expected to form in systems where giants originated rapidly through GI. As a specific example, we suggest that the SA processes led to the formation of the 7.5 $M_\oplus$ planet around GJ 876 and predict that it may have an atmosphere and envelope rich in O$_2$ and liquid water. Assessments of the ubiquity of these planets will lead to 1) the detection of the first habitable terrestrial planets, 2) the verification of the dominant mode of planet formation, 3) an estimate of the fraction of earth-harboring stars, and 4) modification of bio-marker signatures.

description: In this paper we study a black hole phase transition in a generalized JT gravity noticed in arXiv:2006.03494. We investigate the effect of the phase transition on the Euclidean geodesic and holographic two-point function in models with dilaton potential which interpolates two ordinary JT gravities with different cosmological constants. It is noted that there exists a closed geodesic with a new scale at low temperature phase when the potential has a locally negative region. This scale causes several peaks in the two-point function. We also comment on the phase transition of charged black holes. We then consider coupling generalized JT gravity to a matter and study its relation to a $T\bar{T}$ deformation of CFT at the classical level. We find the deformation parameter as a function of the dilaton and provide examples showing Janus-type couplings.

Symmetrically Tuned Large-Volume Conic Shell-Cavities for Axion Searches

description: In an earlier paper, a new class of thin-shell cavities were proposed to evade the steep frequency scaling of conventional axion haloscopes. In this follow-up work, we see that a generalized conic geometry enables robust frequency-tuning for these large-volume cm-wave cavities. The frequency-defining dimension of a conic shell-cavity changes symmetrically and uniformly during tuning, maintaining a high axion coupling efficiency (the form factor) to an external solenoid field. It is further shown that such tunable geometry is not restricted to circular cones. A general prescription for arbitrary volume-filling conic shell-cavities is developed and direct solutions are obtained for the created numerical models. The largest of the realized designs is a meandering "brain" cavity that is tunable over a frequency range of 20%. The scan rate of this cavity is three orders of magnitude larger than that of a scaled cylindrical cavity used in the current generation experiments. The prospects for such a large improvement in the scan rate should motivate R & D efforts in fabrication and other implementation techniques. If these engineering challenges can be met, cavity-based axion haloscopes can stay competitive at frequencies higher than a few GHz. We propose an experimental configuration at 20 GHz (~ 80 $μ$eV) using an array of brain cavities and compare it with other proposals for similar frequencies.

Intelligent hierarchical control of a deployable manipulator
Creators: name: Goulet, Jean-Francois
Publisher: name: University of British Columbia
Year: 2009

description: This thesis focuses on the development and implementation of an intelligent hierarchical controller for a deployable manipulator that may be used in space- and ground-based applications. The emphasis is on the use of knowledge-based tuning of the low-level controllers so as to realize accurate operation under complex and incompletelyknown conditions, with a degree of autonomy. The robot that is investigated consists of two links: one free to slew (revolute joint) while the other allowed to deploy (prismatic joint). A three-level hierarchical system is developed, to control the manipulator. In the bottom layer of the hierarchy, a conventional proportional-integral-derivative (PID) controller is used, for regulating the manipulator joints. The middle layer monitors the performance of the joints of the manipulator, preprocesses the response signals, and extracts the performance parameters, based on a step-input response. The top layer makes inferences for appropriate tuning actions on the PID servos. A decision table is developed using linguistic rules of expert knowledge in tuning PID servos, in order to facilitate fast decision making in the top layer. The knowledge that is contained in this rulebase is acquired from available sources, and represented and processed using the fuzzy logic theory. The governing equations of motion for the ground-based manipulator are developed using the Lagrangian procedure. A Turbo C program is written for the groundbased simulations of the system, which incorporates the manipulator model and the hierarchical control system. Extensive ground-based simulations are carried out for trajectory following tasks. The space-based simulations are also carried out, making use of an existing Fortran program for a robot model tracking a trajectory. These simulations incorporate proportional-derivative control, along with the feedback linearization technique (FLT). An extensive study is carried out to determine the sensitivity of the performance of the control system to changes in the knowledge base. The developed control system is implemented on an existing prototype manipulator, in laboratory. The control software is written in Watcom C, and the manipulator is controlled using the QNX operating system, for real-time operation. A number of trajectory-following experiments were carried out. The study shows a good level of agreement between the ground-based simulations and experiments, with excellent performance of the manipulator when operated under the hierarchical control system. Since the space-based simulations also show good performance through the hierarchical control system, it can be concluded that the developed control system is an appropriate option for controlling space-based manipulators as well. The study further shows that, even in the absence of autotuning, knowledge-based tuning of the servo controllers of the manipulator at strategic task configurations can lead to a significant improvement in performance of practical manipulators.
The Effect of a Magnetic Field on the Dynamics of Debris Discs Around White Dwarfs

description: Observational estimates of the lifetimes and inferred accretion rates from debris discs around polluted white dwarfs are often inconsistent with the predictions of models of shielded Poynting-Robertson drag on the dust particles in the discs. Moreover, many cool polluted white dwarfs do not show any observational evidence of accompanying discs. This may be explained, in part, if the debris discs had shorter lifetimes and higher accretion rates than predicted by Poynting-Robertson drag alone. We consider the role of a magnetic field on tidally disrupted diamagnetic debris and its subsequent effect on the formation, evolution, and accretion rate of a debris disc. We estimate that magnetic field strengths greater than $\sim$10kG may decrease the time needed for circularisation and the disc lifetimes by several orders of magnitude and increase the associated accretion rates by a similar factor, relative to Poynting-Robertson drag. We suggest some polluted white dwarfs may host magnetic fields below the typical detectable limit and that these fields may account for a proportion of polluted white dwarfs with missing debris discs. We also suggest that diamagnetic drag may account for the higher accretion rate estimates among polluted white dwarfs that cannot be predicted solely by Poynting-Robertson drag and find a dependence on magnetic field strength, orbital pericentre distance, and particle size on predicated disc lifetimes and accretion rates.

description: I2AM PARIS is an open data exchange platform for climate and energy policy modelling, developed by the Horizon 2020 PARIS REINFORCE project. Drawing from the current capabilities of the platform, this report provides a summary of platform improvements in the context of the IAM COMPACT project. Notably, efforts will be placed in adding validity checks for modelling data that is uploaded to the platform and providing an indication of whether modelling results are credible by comparing them with relevant benchmarks such as the vetting criteria from IPCC AR6 WGIII. We will also develop user-friendly interfaces for data input, allowing modellers from other projects to easily interact with, and add new modelling and scenario information to, the platform. Existing components of the platform will be also improved in term of functionalities. New model documentation will be added, while the existing documentation will be updated, emphasising interpretability by non-experts. In this direction, we will also create a component with videos and training material for new modellers. Finally, the representation of sectoral models will be enhanced in existing components, while new result workspaces will be created to showcase the outcomes of the project’s modelling exercises.

description: We studied the dynamics of a quasi-one-dimensional chain-like system of charged particles at low temperature, interacting through a screened Coulomb potential in the presence of a local constriction. The response of the system when an external electric field is applied was investigated. We performed Langevin molecular dynamics simulations for different values of the driving force and for different temperatures. We found that the friction together with the constriction pins the particles up to a critical value of the driving force. The system can depin \emph{elastically} or \emph{quasi-elastically} depending on the strength of the constriction. The elastic (quasi-elastic) depinning is characterized by a critical exponent $β\sim0.66$ ($β\sim0.95$). The dc conductivity is zero in the pinned regime, it has non-ohmic characteristics after the activation of the motion and then it is constant. Furthermore, the dependence of the conductivity with temperature and strength of the constriction was investigated in detail. We found interesting differences between the single and the multi-chain regimes as the temperature is increased.

description: A consolidated CDE plan, able to ensure high academic excellence and societal impact at the same time, is considered a key aspect of the IAM COMPACT activities to reinforce the  European and global scientific community, underpin climate policymaking, and enhance the science-policy interface in the light of the Paris Agreement and associated challenges. That said, all corresponding CDE activities lie at the core of IAM COMPACT, with the aim to establish a two-way profitable interdisciplinary and science-policy/science-society dialogue in a timely manner and via the best means and channels available.

This document details the CDE plan to be employed for the entire duration of IAM COMPACT. It outlines both the centrally led outreach activities and tools developed to ensure the efficient uptake and replication of the IAM COMPACT outcomes, and the decentralised efforts to be applied towards reaching and involving all interested actors and target groups through each partner’s stakeholder engagement process and contacts. In doing so, it provides clear guidance that considers “why”, “who”, “what”, “when”, and “how” to engage, as well as the promotional and informational materials that are fundamental for project outreach, and the measures to assess the successful implementation of the CDE activities.

Overall, the IAM COMPACT CDE activities are on track, following the initial plan laid out in the Grant Agreement. The focus is then placed on making the entire consortium committed to actively contributing to and boosting the impact and the exploitation potential of IAM COMPACT.

description: Trends in recent years have indicated that a significant percentage of weekend traffic is recreational and that the proportion of weekend trips is increasing. The "energy crisis" in late 1973, and the associated reduction in speed limit on March 1, 1974, affected weekend travel. A previous study by the Division of Research revealed that significant reductions in the number and rates of highway accidents, fatalities, and injuries coincided with the period of time generally referred to as the "energy crisis". Lower speeds were considered to be a primary factor in the reduction of accidents. An alteration in weekend and holiday trips was suspected of contributing to the reduction of accident rates; however, information was lacking from which to make this determination. A comparison of accidents during weekday, weekend, and holiday periods was made; most of the data were for rural sections of two-lane roads, four-lane roads, interstate routes, and toll roads.  On rural roads, the largest number of accidents have occurred on Saturdays, Fridays, and Sundays. Tuesdays generally had the lowest number of accidents. Fatal accidents on two-lane roads occurred in similar random patterns of distribution during the week. The highest rates for two-lane roads were on Sundays and Saturdays, and the rates for expressways (interstates and toll roads) were the highest on Sundays. Fatality rates were distributed similarly to the rates of all accidents.  The percentage of accidents on weekends decreased steadily from 35 in 1973 to 32 in 1976. likewise, the percentage of fatalities on weekends showed gradual decreases. Accident rates on weekends were substantially higher than on weekdays. Rates of fatal and an accidents were lower during holiday periods than during weekends not involving holidays. Holiday periods had fewer accidents per day than weekends but had more accidents per day than weekdays. Traffic volumes, however, were significantly greater during holidays than on either weekends or weekdays.

description: We construct an infinite class of eigenmodes with integer eigenvalues for the Vacuum Modular Hamiltonian of a single interval $N$ in 2d CFT and study some of its interesting properties, which includes its action on OPE blocks as well as its bulk duals. Our analysis suggests that these eigenmodes, like the OPE blocks have a natural description on the so called kinematic space of CFT$_2$ and in particular realize the Virasoro algebra of the theory on this kinematic space. Taken together, our results hints at the possibility of an effective description of the CFT$_2$ in the kinematic space language.

description: Statewide survey of skid resistances continued in 1979 with the testing of 3,060 miles (4,930 km) of roads, including interstate and toll roads. During the two-year (1978 and 1979) cycle of testing, over 7,000 miles (11,270 km) of roads have been tested. Altogether, 560 miles (902 km) of roads had an average skid number of 28 or less. These pavements, in particular, should be considered for deslicking.  In 1978 and 1979, 28 percent of the state-maintained roads were surveyed. These roads carried 72 percent of all traffic on state-maintained roads.

description: Strongly interacting many-body system of bosons exhibiting the quantum carpet pattern is investigated exactly by using Gaudin solutions. We show that this highly coherent design usually present in noninteracting, single-body scenarios gets destroyed by weak-to-moderate interatomic interactions in an ultracold bosonic gas trapped in a box potential. However, it becomes revived in a very strongly interacting regime, when the system undergoes fermionization. We track the whole single- to many-body crossover, providing an analysis of de- and rephasing present in the system.

description: The PandaX-III experiment uses high pressure gaseous time projection chamber to search for the neutrinoless double beta decay of $^{136}$Xe. A modular slow control system~(SCS) has been designed to monitor all the critical parameters of the experiment. It ensures the proper operation of the experiment as well as to provide necessary information for data corrections. The main subsystems of the experiment will be constantly monitored by the data collection module of the SCS, which collects data from sensors and sends them to the centralized database. When an alarm message is generated by the anomaly detection module, it will be sent to an alert website and related on-call experts immediately. A demonstrator of the SCS has been built for the PandaX-III prototype detector. The long-term test of it provided valuable experience for the final design of the SCS for PandaX-III.

description: We analysis the quantum Hall effect exhibited by a system of particles moving in a higher dimensional space. This can be done by considering particles on the Bergman ball {\bb{B}_ρ^d} of radius ρin the presence of an external magnetic field B and investigate its basic features. Solving the corresponding Hamiltonian to get the energy levels as well as the eigenfunctions. This can be used to study quantum Hall effect of confined particles in the lowest Landau level where density of particles and two point functions are calculated. We take advantage of the symmetry group of the Hamiltonian on {\bb{B}_ρ^d} to make link to the Landau problem analysis on the complex projective spaces CP^d. In the limit ρ\lga\infty, our analysis coincides with that corresponding to particles on the flat geometry {\bb{C}^d}. This task has been done for d=1, 2 and finally for the generic case, i.e. d \geq 3.

description: Cystinosis is a severe inherited metabolic storage disease caused by the lysosomal accumulation of cystine. Lifelong therapy with the drug cysteamine bitartrate is necessary. Cysteamine cleaves intralysosomal cystine, and thereafter, it can exit from the organelle. The need for frequent dosing every 6 h and the high prevalence of gastrointestinal side effects lead to poor therapy adherence. The purpose of our study was to improve cysteamine treatment by comparing the efficacy of two cysteamine formulas. This is highly relevant for the long-term outcome of cystinosis patients. The cystine and cysteamine levels of 17 patients taking immediate-release cysteamine (IR-cysteamine/Cystagon®) and 6 patients taking encapsulated delayed-release cysteamine (EC-cysteamine) were analyzed. The EC-cysteamine levels showed a near-ideal pharmacokinetic profile indicative of delayed release (longer Tmax and Tmin), and the corresponding cystine levels showed few fluctuations. In addition, the Cmax of IR-cysteamine was greater, which was responsible for unbearable side effects (e.g., nausea, vomiting, halitosis, lethargy). Treatment with EC-cysteamine improves the quality of life of cystinosis patients because the frequency of intake can be reduced to 2–3 times daily and it has a more favorable pharmacokinetic profile than IR-cysteamine. In particular, cystinosis patients with no access to the only approved delayed-release cysteamine Procysbi® could benefit from a cost-effective alternative.

description: The observation of forward proton scattering in association with lepton pairs ($e^+e^-+p$ or $μ^+μ^-+p$) produced via photon fusion is presented. The scattered proton is detected by the ATLAS Forward Proton spectrometer while the leptons are reconstructed by the central ATLAS detector. Proton-proton collision data recorded in 2017 at a center-of-mass energy of $\sqrt{s} = 13$ TeV are analyzed, corresponding to an integrated luminosity of 14.6 fb$^{-1}$. A total of 57 (123) candidates in the $ee+p$ ($μμ+p$) final state are selected, allowing the background-only hypothesis to be rejected with a significance exceeding five standard deviations in each channel. Proton-tagging techniques are introduced for cross-section measurements in the fiducial detector acceptance, corresponding to $σ_{ee+p}$ = 11.0 $\pm$ 2.6 (stat.) $\pm$ 1.2 (syst.) $\pm$ 0.3 (lumi.) fb and $σ_{μμ+p}$ = 7.2 $\pm$ 1.6 (stat.) $\pm$ 0.9 (syst.) $\pm$ 0.2 (lumi.) fb in the dielectron and dimuon channel, respectively.

description: We present a variational calculation of the spin wave excitation spectrum of double--exchange ferromagnets in different dimensions. Our theory recovers the Random Phase approximation and 1/S expansion results as limiting cases and can be used to study the intermediate exchange coupling and electron concentration regime relevant to the manganites. In particular, we treat exactly the long range three--body correlations between a Fermi sea electron--hole pair and a magnon excitation and show that they strongly affect the spin dynamics in the parameter range relevant to experiments in the manganites. The manifestations of these correlations are many-fold. We demonstrate that they significantly change the ferromagnetic phase boundary. In addition to a decrease in the magnon stiffness, we obtain an instability of the ferromagnetic state against spin wave excitations close to the Brillouin zone boundary.Within a range of intermediate concentrations, we find a strong softening of the spin wave dispersion as compared to the Heisenberg ferromagnet with the same stiffness, which changes into hardening for other concentrations. We discuss the relevance of these results to experiments in colossal magnetoresistance ferromagnets.

We have studied here the role of Berry phase in removing dynamical phase during one qubit rotation of a quantized fermion. The entanglement of two qubit inserting spin-echo to one of them results the change of Berry phase that can be considered as a measure of entanglement. Some effort is given to study the effect of noise on the Berry phase of spinor and their entangled states.

Towards a typology of continuative expressions
Creators: name: Panova, Anastasia
Publisher: name: Linguistic Typology at the Crossroads
Year: 2023

description: This paper investigates the cross-linguistic diversity of continuative (‘still’) expressions. Based on a genealogically stratified sample of 120 languages, the continuative expressions are systematically analyzed according to the four following parameters: morphosyntactic type, emphatic vs. non-emphatic status, other (non-continuative) uses and semantic effects when combined with negation. The study shows that the most widespread type of continuative expressions is represented by monosemous emphatic continuative adverbials which in combination with negation acquire a ‘not yet’ meaning. In many languages, however, we also find continuative expressions which have followed evolutionary pathways towards morphologization, non-emphatic uses, rich polysemy networks, and less trivial types of interaction with negation. The paper discusses possible areal, genealogical and structural factors which might contribute to the “maturation” of continuative expressions in the world’s languages.

description: We numerically study the effects of non-magnetic impurities (vacancies) in the spin-$S$ Heisenberg antiferromagnet on the kagomé lattice. For a range of low but nonzero temperatures, and spin values that extend down to $S=2$, we find that the magnetization response to an external magnetic field is consistent with the response of emergent "half-orphan" degrees of freedom that are expected to dominate the response of the corresponding classical magnet in a similar temperature range whenever there are two vacancies on the same triangle. Specifically, for all spin values we have considered (from $S=1/2$ to $S=4$), there is a large enhancement of the local susceptibility of the lone spin on such a triangle with two vacancies; in the presence of a uniform magnetic field $h$, this lone-spin behaves effectively as an almost free spin $S$ in an effective field $h/2$. Quite remarkably, in the zero temperature limit, the ground state in the presence of a half-orphan has a non-zero total spin value $S_{GS}$ that shows a trend similar to $S/2$ when $S\ge 2$. These qualitative aspects of the response differ strikingly from the more conventional response of diluted samples without such half-orphan degrees of freedom. We discuss how these findings could be checked experimentally.

description: We study the competition to operate an infrastructure service by developing a model where firms must report a two-dimensional sealed bid : the price to consumers and the concession fee paid to the government. Two bidding rules are considered in this paper. One rule consists of awarding the concession to the firm that reports the lowest price. The other consists of granting the franchise to the bidder offering the highest fee. We compare the outcome of these rules with reference to two alternative concession arrangements. The former imposes the obligation to immediately undertake the investment required to roll-out the service. The latter allows the concessionaire to optimally decide the investment timing. The focus is on the effect of bidding rules and managerial flexibility on expected social welfare. We find that the two bidding rules provide the same outcome only when the contract does not restrict the autonomy of the franchisee, and we identify the conditions under which time flexibility can provide a higher social value.

description: The purpose of the present work is to analyse the economic performance and financial standing of a group of farms during the 2002- 2005 period, thus providing an opportunity to evaluate ex-post the effects of the new common agricultural policy orientations. The twenty agricultural enterprises studied occupy a total area of 8,000 acres and are situated in two regions of central-northern Italy: ten of the farms are in Emilia-Romagna and characterised by a prevalence of arable crops, while the remaining ten farms are in Tuscany and produce grapevines and olives in addition to arable crops. This paper presents the results of a profitability and balance sheet analysis of the agricultural enterprises, and examines the reliance of their overall business performance on EU payments. In line with the new directions of community policy, the role of diversification in creating value is specifically addressed, not just in terms of multifunctionality but also from the broader perspective of multiple business activities.

description: The first difference version of the restricted source-differentiated almost ideal demand system is used to estimate South Korean meat demand. The results of this study indicate that the United States has the most to gain from an increase in the size of the South Korean imported meat market in terms of its beef exports, while South Korea has the most to gain from this expansion in the pork market. Moreover, the results indicate that the United States has a competitive advantage to Australia in the South Korean beef market. Results of this study have implications for U.S. meat exports in this ever-changing policy environment.

description: The Southeastern United States depends on coal to supply 60% of its electricity needs. The region leads in CO2 emissions and ranks second in emissions of SO2 and NO2. Compared with coal, biomass feedstocks have lower emission levels of sulfur or sulfur compounds and can potentially reduce nitrogen oxide emissions. This study examines the economic impacts of cofiring level scenarios. Economic impacts are estimated for producing, collecting, and transporting feedstock; retrofitting coal-fired utilities for burning feedstock; operating cofired utilities; and coal displaced from burning the feedstock.
Exactly solvable model of wormhole supported by phantom energy

description: We have found a simple exact solution of spherically-symmetrical Einstein equations describing a wormhole for an inhomogeneous distribution of the phantom energy. The equation of state is linear but highly anisotropic: while the radial pressure is negative, the transversal one is positive. At infinity the spacetime is not asymptotically flat and possesses on each side of the bridge a regular cosmological Killing horizon with an infinite area, impenetrable for any particles. This horizon does not arise if the wormhole region is glued to the Schwarzschild region. In doing so, the wormhole can enclose an arbitrary amount of the phantom energy. The configuration under discussion has a limit in which the phantom energy turns into the string dust, the areal radius tends to the constant. In this limit, the strong gravitational mass defect is realized in that the gravitational active mass is finite and constant while the proper mass integrated over the total manifold is infinite.

description: The paper applies a non-parametric propensity score matching approach to evaluate the effects of two types of farm programs (agri-environment (AE) programs and the less favoured area (LFA) scheme) on input use and farm output of individual farms in Germany. The analysis reveals a positive and significant treatment effect of the LFA scheme for farm sales and the area under cultivation. Participants in AE schemes are found to significantly increase the area under cultivation (in particular grassland), resulting in a decrease of livestock densities. Furthermore, participation in AE programs significantly reduced the purchase of farm chemicals (fertilizer, pesticide). We also find substantial differences in the treatment effect between individual farms (heterogeneous treatment effects). Farms which can generate the largest benefit from the program are most likely to participate.

description: An integrated policy evaluation tool is proposed for assessing the effects of agricultural policy measures using all the information available at farm level. The tool combines the positive mathematical programming methodology with the cluster analysis technique by using the same panel of data. The PMP model proposed here allows to measure the effects of policy in term of agricultural supply responses including output market price variations. The novel procedure by which the PMP model is articulated permits to recover the set of farm level demand functions for agricultural products and the cost function characterizing the given sample of farms. Cluster analysis is useful for better appreciating the behaviour of farms before and after the policy scenario analysis by considering the transfers of farms among clusters. A decoupling scenario assessment presents the responses that the integrated tool can provide for evaluating agricultural policy instruments.

description: The objective of this paper is to provide an impact analysis of the Fruit and Vegetables CMO reform with respect the Italian processed tomato sector, including the evaluation of the effects on agriculture and on tomato industry. The impact on agriculture (tomato sector) at farm level, is evaluated by PMP models applied to FADN farms of Farm Type "fruit and vegetables" acting in Emilia Romagna, Veneto and Puglia. The impact on the industrial component of the chain is analysed in relation with the degree of resistance of processed tomato industries facing a likely positive trend of fresh tomato prices induced by the reform application. Result shows as full decoupling will have a very negative impact if industry doesn't differentiate their production increasing the level of service in their production.
