description: Annealing schedule control provides new opportunities to better understand the manner and mechanisms by which putative quantum annealers operate. By appropriately modifying the annealing schedule to include a pause (keeping the Hamiltonian fixed) for a period of time, we show it is possible to more directly probe the dissipative dynamics of the system at intermediate points along the anneal and examine thermal relaxation rates, for example, by observing the re-population of the ground state after the minimum spectral gap. We provide a detailed comparison of experiments from a D-Wave device, simulations of the quantum adiabatic master equation and a classical analogue of quantum annealing, spin-vector Monte Carlo, and we observe qualitative agreement, showing that the characteristic increase in success probability when pausing is not a uniquely quantum phenomena. We find that the relaxation in our system is dominated by a single time-scale, which allows us to give a simple condition for when we can expect pausing to improve the time-to-solution, the relevant metric for classical optimization. Finally, we also explore in simulation the role of temperature whilst pausing as a means to better distinguish quantum and classical models of quantum annealers.

description: Quantum computing (QC) is a new paradigm offering the potential of exponential speedups over classical computing for certain computational problems. Each additional qubit doubles the size of the computational state space available to a QC algorithm. This exponential scaling underlies QC's power, but today's Noisy Intermediate-Scale Quantum (NISQ) devices face significant engineering challenges in scalability. The set of quantum circuits that can be reliably run on NISQ devices is limited by their noisy operations and low qubit counts. This paper introduces CutQC, a scalable hybrid computing approach that combines classical computers and quantum computers to enable evaluation of quantum circuits that cannot be run on classical or quantum computers alone. CutQC cuts large quantum circuits into smaller subcircuits, allowing them to be executed on smaller quantum devices. Classical postprocessing can then reconstruct the output of the original circuit. This approach offers significant runtime speedup compared with the only viable current alternative--purely classical simulations--and demonstrates evaluation of quantum circuits that are larger than the limit of QC or classical simulation. Furthermore, in real-system runs, CutQC achieves much higher quantum circuit evaluation fidelity using small prototype quantum computers than the state-of-the-art large NISQ devices achieve. Overall, this hybrid approach allows users to leverage classical and quantum computing resources to evaluate quantum programs far beyond the reach of either one alone.

description: This paper aims at analysing the role of the environment in innovative strategies based on firm economic performance indicators such as employment, turnover, and labour productivity growth. We exploit a unique dataset of 773 Italian service firms with 20 or more employees comprising 1993-1995 CIS II data on firm innovation strategic motivations and 1995-1998 data on employment, turnover, and labour productivity from the System of the Enterprise Account (SEA). We specify a Gibrat-like empirical model in which the covariates include firm strategies (innovation and environmental), and a set of other explanatory variables and controls. Our econometric findings show a negative link between environmental motivations and growth in employment and turnover and a consequent not significant effect on labour productivity growth. The effect on employment is partly in line with past evidence and may derive from efficiency improvements (dematerialization processes) which also impact on efficiency by reducing workforce number. It is plausible that the net effect derives from the absence of low skilled employment and a creation of high skilled jobs, as a consequence of increased environmental awareness. The effect on turnover shows a negative impact from environmental innovation strategy, implying either a short-medium effect, possibly balanced in the long run by net benefits in terms of higher added value, or a real negative impact, which may be contingent on the observed period, when environmental strategies where not at the heart of strategic management policies. However, productivity-related effects (the core of performance indicators) are not significant. Mainstream hypotheses related to eventual negative impacts are thus not confirmed, although Porter-like effects and virtuous circles between environmentally strategies and performance do not seem to be present.
Inadequate Management and Declining Infrastructure: The Critical Recurring Cost Problem Facing Irrigation in Asia

description: This report reviews the recurring costs situation for irrigation in Asia. These are the costs associated with project operation and maintenance (O&M). As is well documented in the literature many developing countries have neglected project O&M which has resulted in a rapid depreciation of past irrigation investments (Carruthers, 1981). Irrigation systems fail to irrigate their planned or projected command areas and after a few years parts of the systems no longer function (Wade, 1975). The problem is that there are too few farmer or government agency incentives which foster investment of capital and human resources in O&M and assure that irrigation projects operate at a high level of performance over a long period of time. For example, there is lack of accountability for O&M because of the weak linkage between those providing O&M and those benefiting from O&M.
A unifying formulation of the Fokker-Planck-Kolmogorov equation for general stochastic hybrid systems

description: A general formulation of the Fokker-Planck-Kolmogorov (FPK) equation for stochastic hybrid systems is presented, within the framework of Generalized Stochastic Hybrid Systems (GSHS). The FPK equation describes the time evolution of the probability law of the hybrid state. Our derivation is based on the concept of mean jump intensity, which is related to both the usual stochastic intensity (in the case of spontaneous jumps) and the notion of probability current (in the case of forced jumps). This work unifies all previously known instances of the FPK equation for stochastic hybrid systems, and provides GSHS practitioners with a tool to derive the correct evolution equation for the probability law of the state in any given example.

description: We reformulate the Lanczos algorithm for quantum wave function propagation in terms of variational principle. By including some basis states of previous time steps into the variational subspace, the resultant accuracy increases by several orders. Numerical errors of the alternative method accumulate much slower than that of the original Lanczos method. There is almost no extra numeric cost for the gaining of the accuracy, i.e., the accuracy increase needs no extra operations of the Hamiltonian acting on state vectors, which are the major numeric cost for wave function propagation. A wave packet moving in a 2-dimensional Hénon-Heiles model serves as an illustration. This method is suitable for small time step propagation of quantum wave functions in large scale time dependent calculations where the operations of the Hamiltonian acting on state vectors are expensive.

description: Sum rules in the lepton sector provide an extremely valuable tool to classify flavour models in terms of relations between neutrino masses and mixing parameters testable in a plethora of experiments. In this manuscript we identify new leptonic sum rules arising in models with modular symmetries with residual symmetries. These models simultaneously present neutrino mass sum rules, involving masses and Majorana phases, and mixing sum rules, connecting the mixing angles and the Dirac CP-violating phase. The simultaneous appearance of both types of sum rules leads to some non-trivial interplay, for instance, the allowed absolute neutrino mass scale exhibits a dependence on the Dirac CP-violating phase. We derive analytical expressions for these novel sum rules and present their allowed parameter ranges as well as their predictions at upcoming neutrino experiments.

description: Veritas-Pro and Veritas-PRN are instruments to assess adherence to treatment of people with hemophilia. Low adherence can limit treatment effectiveness and result in increased bleeding episodes and chronic pain. The purpose of this study was to adapt both questionnaires into French, report preliminary psychometric data in a group of pediatric patients and their parents, and compare ratings between young patients and their parents. The translation process followed these steps: (1) forward translation (2) backward translation (3) final version, and (4) testing. Translators were familiar with the pediatric community. Thirteen pediatric patients and twenty parents participated in the study. The translation process was conducted without major difficulties, and children easily understood the French versions. Preliminary psychometric analyses showed good to excellent consistency for the total scale and most subscales. However, the consistency of the Dose (VERITAS-Pro) and the Plan (VERITAS-PRN) subscales were low. When pediatric patients were primary infusers, they reported more skipping of prophylaxis than in parents’ estimation of their behavior. For episodic treatment, when parents were primary infusers, they reported better adherence for the Time subscale vs. children’s estimation of their behavior. Parents also rated higher adherence on prophylaxis when they were themselves in charge of performing the infusions than when young patients were autonomous. Preliminary psychometric analyses support the use of the French versions for the total scale and most subscales. However, the results did not support the use of the subscales Dose (VERITAS-Pro) and Plan (VERITAS-PRN) in the adapted versions. Further studies should be performed on larger samples.

description: It is demonstrated that the infrared renormalon calculus indicates that the QCD theoretical expressions for the Gross-Llewelln Smith sum rules and for the Bjorken polarized and unpolarized ones contain an identical negative twist-4 1/Q^2 correction. This observation is supported by the consideration of the results of calculations of the corresponding twist-4 matrix elements. Together with the indication of the similarity of perturbative QCD corrections to these three sum rules, this observation leads to simple new theoretical relations between the Gross-Llewellyn Smith and Bjorken polarized and unpolarized sum rules in the energy region $Q^2\geq 1 GeV^2$. The validity of this relation is checked using concrete experimental data for the Gross-Llewellyn Smith and Bjorken polarized sum rules

description: China’s economy has grown at an impressive rate after the integration into the global trading system (WTO) in 2001, a major turning point in the Chinese economic history. The opening policy has increased business opportunities for both local and foreign operators; however, in spite of the great appeal of such cooperation, many obstacles yet exist: language, culture, education, business practices, and industrial development. Food products supply and access to the market are mastered by a relatively small group of businessmen: international buyers, purchasing agents, retailers and representatives of large-scale distribution chains. The perception they have of a potential source country is a key factor for a successful market approach. The present study aims at understanding the attitudes of distribution practitioners in the Chinese market towards imported Italian quality wine, as well as the current communication, marketing, strategic and organizational advantages or deficiencies of Italian producers, compared to other European counterparts. The primary data were collected through personal interviews with key informants in Shanghai, Beijing and Guangzhou. Such information has been completed with an analysis of the existing literature, meetings with sector operators as well as with talks and presentations of experts attending the “International Workshop on Chinese Wine Market”, held in Beijing on August 8-10, 2007. The interviews have been administered as conversation-like dialogues, on the base of a semi-structured interview outline, providing also the framework for a qualitative content analysis. This paper is aimed at giving an insight on import and distribution of Italian wine in China, highlighting both positive and negative feedbacks on the effectiveness of marketing strategies of Italian wine trading companies.

description: We exploit insights into the geometry of bosonic and fermionic Gaussian states to develop an efficient local optimization algorithm to extremize arbitrary functions on these families of states. The method is based on notions of gradient descent attuned to the local geometry which also allows for the implementation of local constraints. The natural group action of the symplectic and orthogonal group enables us to compute the geometric gradient efficiently. While our parametrization of states is based on covariance matrices and linear complex structures, we provide compact formulas to easily convert from and to other parametrization of Gaussian states, such as wave functions for pure Gaussian states, quasiprobability distributions and Bogoliubov transformations. We review applications ranging from approximating ground states to computing circuit complexity and the entanglement of purification that have both been employed in the context of holography. Finally, we use the presented methods to collect numerical and analytical evidence for the conjecture that Gaussian purifications are sufficient to compute the entanglement of purification of arbitrary mixed Gaussian states.

description: We make use of data from the 2005 Albania Living Standard Measurement Survey to investigate the factors affecting household agriculture efficiency and land market development. To assess the functioning of land rental markets and explore efficiency- and equity impacts of land rental, we use a model of producers who differ in endowments and skills and who face imperfect labor markets and transaction costs. The empirical evidence, of a stochastic frontier estimate, shows that productivity is low and most farms are inefficiently utilized. The average level of agriculture efficiency among rural household is very less than 30% but household that rent in land are more efficient. However, results from a probit regression on rental market participation shows that rental market helps to transfer land to more efficient producers. However, several constraints in credit market, input, labor, and the lack of irrigation are outweighing the productivity advantage of the tenants. In addition to that, land market development is delayed by remaining restrictions and high transaction cost. To overcome these limitations as well as inadequate system of land title registration, household are using informal land transactions, such as inheritance, in order to increase farming efficiency.

description: The main co-ordinators/channels used in Hungarian fruit and vegetable supply chain are the following: local market, wholesale markets, production co-operatives, marketing cooperatives, producers' organisation, processing industry, wholesalers and retailers. Different retail chains gain a progressively larger share of the fresh fruit and vegetable market. It is very important, therefore, that the farmers have to use marketing channels which could give them the strengths (countervailing power) of more concentrated organisations. In this case study, we examine the integration role of Mórakert Purchasing and Service Co-operative, in Mórahalom in county Csongrád which can be found in the southern east part of Hungary. The Morakert co-operative active in the fruit and vegetable sector and it was the first officially acknowledged Producers' Organisation (PO) in Hungary. It works as a very successful cooperative (e.g. in terms of increasing annual turnover and membership) thus being a good example for a number of emerging producer organisations.

The questions of how such chain networks have to be designed and which governance structure fits best have been addressed in several well known articles. However, questions dealing with chain strategy and management are not discussed satisfyingly. Neither is the understanding of what is success of chain management distinguished. A comprehension of these aspects can have crucial implications for the agribusiness of transition countries. Thus, we will address these questions with regard to Ukraine.

description: Muscle activation patterns of the dominant and non-dominant arm were compared during two unconstrained throwing tasks (dart throws, underhand throws). Electromyographic (EMG) signals were recorded from shoulder (anterior and posterior deltoid), upper arm (biceps and triceps brachii) and hand (thenar) muscles in 12 healthy volunteers. Mean and peak EMG amplitudes of both arms did not differ significantly and their EMG curves were nearly congruent. Also, the timing of the EMG bursts was alike for the dominant and non-dominant arm in both throwing tasks, with the exception of one muscle (posterior deltoid). EMG activity of this muscle, which is an antagonist during dart and underhand throws, started significantly later on the non-dominant side than on the dominant side. The mean interlimb differences were 17 ms for dart throws and 35 ms for underhand throws. Higher spatial accuracy of throws was associated with less hand (thenar) muscle activity regardless of the side (dominant, non-dominant). The conspicuous similarity of the EMG curves of both arms speaks in favour of motor equivalence, indicating that the activation of dominant and non-dominant agonist muscles is controlled by the same motor program during unconstrained throwing.

description: In this paper we investigate the critical collapse of an ultrarelativistic perfect fluid with the equation of state $P=(Γ-1)ρ$ in the limit of $Γ\to 1$. We calculate the limiting continuously self similar (CSS) solution and the limiting scaling exponent by exploiting self-similarity of the solution. We also solve the complete set of equations governing the gravitational collapse numerically for $(Γ-1) = 10^{-2},...,10^{-6}$ and compare them with the CSS solutions. We also investigate the supercritical regime and discuss the hypothesis of naked singularity formation in a generic gravitational collapse. The numerical calculations make use of advanced methods such as high resolution shock capturing evolution scheme for the matter evolution, adaptive mesh refinement, and quadruple precision arithmetic. The treatment of vacuum is also non standard. We were able to tune the critical parameter up to 30 significant digits and to calculate the scaling exponents accurately. The numerical results agree very well with those calculated using the CSS ansatz. The analysis of the collapse in the supercritical regime supports the hypothesis of the existence of naked singularities formed during a generic gravitational collapse.

description: Deep-predictive-coding networks (DPCNs) are hierarchical, generative models. They rely on feed-forward and feed-back connections to modulate latent feature representations of stimuli in a dynamic and context-sensitive manner. A crucial element of DPCNs is a forward-backward inference procedure to uncover sparse, invariant features. However, this inference is a major computational bottleneck. It severely limits the network depth due to learning stagnation. Here, we prove why this bottleneck occurs. We then propose a new forward-inference strategy based on accelerated proximal gradients. This strategy has faster theoretical convergence guarantees than the one used for DPCNs. It overcomes learning stagnation. We also demonstrate that it permits constructing deep and wide predictive-coding networks. Such convolutional networks implement receptive fields that capture well the entire classes of objects on which the networks are trained. This improves the feature representations compared with our lab's previous non-convolutional and convolutional DPCNs. It yields unsupervised object recognition that surpass convolutional autoencoders and are on par with convolutional networks trained in a supervised manner.

description: The paper investigates the impacts of trust on the relationships among members and between members and the management in an agricultural marketing cooperative in the Hungarian horticultural sector. We focus on the effects of trust on cooperative members' performance and satisfaction and their commitment to remaining a part of cooperative. We analyse the trust along two dimensions: cognitive and affective. Our results suggest that trust among cooperative members and trust between cooperative and management have positive effects on group cohesions. In line with a priori hypotheses we found differences between cognitive and affective trust influencing the group cohesion and cooperative members' satisfaction.

The GFFs, $A(Q^2)$ and $B(Q^2)$ are found to be consistent with the lattice QCD, while the qualitative behavior of the $D$-term form factor is in agreement with the extracted data from the deeply virtual Compton scattering (DVCS) experiments at JLab, the lattice QCD, and the predictions of different phenomenological models. The pressure and shear force distributions are also consistent with the results of different models.

description: Using the resonant-state expansion for leaky optical modes of a planar Bragg microcavity, we investigate the influence of disorder on its fundamental cavity mode. We model the disorder by randomly varying the thickness of the Bragg-pair slabs (composing the mirrors) and the cavity, and calculate the resonant energy and linewidth of each disordered microcavity exactly, comparing the results with the resonant-state expansion for a large basis set and within its first and second orders of perturbation theory. We show that random shifts of interfaces cause a growth of the inhomogeneous broadening of the fundamental mode that is proportional to the magnitude of disorder. Simultaneously, the quality factor of the microcavity decreases inversely proportional to the square of the magnitude of disorder. We also find that first-order perturbation theory works very accurately up to a reasonably large disorder magnitude, especially for calculating the resonance energy, which allows us to derive qualitatively the scaling of the microcavity properties with disorder strength.

description: Purpose: Cardiorespiratory fitness (CRF) is a predictor of lower mortality in patients with coronary artery disease (CAD) and cancer patients. Whether cancer survivors with preserved ejection fraction (EF) have a higher fitness level than patients with stable CAD and heart failure with preserved EF (HFpEF) is unknown. Methods: We enrolled 61 cancer survivors with an EF >50% (mean age 56.9 years ± 12.4), 60 patients with HFpEF and stable CAD (mean age 58.9 years ±8.1) and 60 healthy control subjects (mean age 61.2 years±9.9) to perform cardiopulmonary exercise testing (CPET) in our outpatient sports medical centre. Results: Maximal power [W] was inferior in cancer survivors (mean: 141.52W ± 67.43; CI: 124.26–158.79 W) than in HFpEF patients (mean: 157.90W ± 58.31; CI: 142.84W-172.96W) and healthy controls (mean: 196.58 W ± 79.37; CI: 176.08–217.09W). Performance at the individual anaerobic threshold (IAT; p = .033) and ventilatory compensation point (VCP, p = .003) were worse in the cancer and HFpEF groups than in the controls. Conclusion: CRF is significantly inferior in stable CAD patients with preserved EF and in cancer patients than in matched controls. There is a trend that cancer survivors even perform worse than HFpEF patients. Regular follow-up of CRF in these two groups is crucial for early detection of health deterioration in these seemingly stable patients.

We also use the 1420 MHz images from the CGPS to study their 408-1420 MHz spectral indices. The flux densities at 408 MHz and 1420 MHz, corrected for flux densities from compact sources within the SNRs, are 12$\pm$6 Jy and 9.8$\pm$0.8 Jy for G114.3+0.3, 15.0$\pm$1.5 Jy and 10.6$\pm$0.6 Jy for G116.5+1.1, 15.0$\pm$1.5 Jy and 8.1$\pm$0.4 Jy for G116.9+0.2. The integrated flux density-based spectral indices (S$_ν$$\propto$$ν$$^{-α}$) are $α$=0.16$\pm$0.41, 0.28$\pm$0.10 and 0.49$\pm$0.09 for G114.3+0.3, G116.5+1.1 and G116.9+0.2, respectively. Their T-T plot-based spectral indexes are 0.68$\pm$0.48, 0.28$\pm$0.15, and 0.48$\pm$0.04, in agreement with the integrated flux density-based spectral indices. New flux densities are derived at 2695 MHz which are significantly larger than previous values. The new 408, 1420 and 2695 MHz flux densities and published values at other frequencies, where images are not available, are fitted after correcting for contributions from compact sources, to derive their multi-frequency spectral indices.

description: The nowadays development in agribusiness can be characterised as shifting of power to the finalising levels and distribution in food commodity chains, which influence as well as form competitive environment of farm and also food-processing companies. The dependence of producers (farmers) on finalising stage is increasing, as well as the risk is transferred and the marked power is enforced in food commodity chains. Those factors are changing proportions, conditions of approach and share of individual stages of commodity chain on value added launched in final product. Possible approach to the identification of market power within food commodity chains is the approach based on price transmission analysis; inelastic price transmission (especially in case of price growth) can imply the existence of market power at certain market level of the commodity chain. This approach - with the distinction of dairy products with low or high value added - is applied on dairy commodity chain in conditions of the Czech Republic.

description: Muscle activation patterns of the dominant and non-dominant arm were compared during two unconstrained throwing tasks (dart throws, underhand throws). Electromyographic (EMG) signals were recorded from shoulder (anterior and posterior deltoid), upper arm (biceps and triceps brachii) and hand (thenar) muscles in 12 healthy volunteers. Mean and peak EMG amplitudes of both arms did not differ significantly and their EMG curves were nearly congruent. Also the timing of the EMG bursts was alike for the dominant and non-dominant arm in both throwing tasks, with the exception of one muscle (posterior deltoid). EMG activity of this muscle, which is an antagonist during dart and underhand throws, started significantly later on the non-dominant side than on the dominant side. The mean interlimb differences were 17 ms for dart throws and 35 ms for underhand throws. Higher spatial accuracy of throws was associated with less hand (thenar) muscle activity regardless of the side (dominant, non-dominant). The conspicuous similarity of the EMG curves of both arms speaks in favour of motor equivalence, indicating that the activation of dominant and non-dominant agonist muscles is controlled by the same motor program during unconstrained throwing.

description: This paper deals with the estimation of a random coefficient model. The virtue of this approach is that it considers firm heterogeneity, which conventional SFA models do not. Applying the model to Polish farms, the results indicate that the conventional random and fixed effect models overestimate the inefficiency score. In addition, the reasons for inefficiency are analysed. It is shown that despite the fragmentation of Polish agriculture, there is no evidence for scale inefficiency. Moreover, inefficiency could partly be attributed to factors, which affect the management input and requirements on farms.
The Shape of Full Configuration Interaction to Come

description: We present a perspective on what the future holds for full configuration interaction (FCI) theory, with an emphasis on conceptual rather than technical details. Upon revisiting the early history of FCI, a number of its key contemporary approximations are compared on as equal a footing as possible, using a recent blind challenge on the benzene molecule as a testbed [Eriksen et al., J. Phys. Chem. Lett., 11, 8922 (2020)]. In the process, we review the scope of applications for which FCI continues to prove indispensable, and the required traits in terms of robustness, efficacy, and reliability its modern approximations must satisfy are discussed. We close by conveying a number of general observations on the merits offered by the state-of-the-art alongside some of the challenges still faced to this day. While the field has altogether seen immense progress over the years - the past decade, in particular - it remains clear that our community as a whole has a substantial way to go in enhancing the overall applicability of near-exact electronic structure theory for systems of general composition and increasing size.

$CP$ asymmetries in the rare top decays $t\to cγ$ and $t\to c g$

description: The rare radiative flavour changing top decays $t\to cγ$ and $t\to cg$ (and the even rarer $t\to uγ$ and $t\to ug$) have been processes of interest for decades as they offer a key probe for studying top quark properties. However an explicit analytical study of the branching ratios and $CP$ asymmetries resulting from these loop level processes has thus far evaded attention. In this work, we provide the formulation for the $CP$ asymmetry resulting from the total kinetic contribution of the loop integrals and their imaginary parts, as well as an updated numerical computation of the predicted Standard Model (SM) branching fractions. These rare processes are suppressed in the SM by the Glashow-Iliopoulos-Maiani (GIM) mechanism. However, the results presented here can easily be exported for use in minimal extensions of the SM including vector-like quarks or in Two-Higgs-Doublet models where radiative fermionic decay processes can be enhanced relative to the SM by several orders of magnitude. Such processes provide an experimentally clean signature for new fundamental physics and can potentially be tested by current collider experiments. These topical beyond the SM theories are an elegant means to provide improved global fits to the latest results emerging from flavour physics, CKM and precision electroweak measurements.

description: The paper deals with the key issues of contemporary food system development and their economic content related to the position of agricultural enterprises. It explains, that the problem faced by the whole Europe and thus also by the Czech Republic, i.e. how to compete successfully on an increasingly globalised food market, fully concerns the shaping of a new agriculture structure and all its sectors, which are more-or-less related to the food and non food sector based upon agricultural raw materials production. By generalising the typical features in the running integration processes within this economy segment, essential tendencies of changes in the present-day business environment which affect both the supply and demand sides of market formation, concerning production, processing and merchandise of food are characterised. New challenging approaches for agricultural enterprises as well as from the the CAP regulation policy point of view in this business branch are evaluted there.

description: Omnipresent control of Uzbekistan government in agriculture undermines land tenure security among the farmers and as result leads to low productivity and low incentives for investment into the land. In its turn low productivity in cotton farms worries the Uzbek policy makers on whether giving more freedom to 'private' farms will adversely alter vital production of cotton. In this study we hypothesized on opportunity of enhancing land tenure security in today's Uzbekistan without altering government's demand for cotton. Specifically we showed that relaxing requirement over the land occupation under cotton while leaving only government demand for output will result in freeing significant percentage of land area and consequently enhancing land [property] rights. Indeed, our estimates suggest that depending on the soil quality and entrepreneurship skills of farmer, from 3% to 6% of farm lands can be potentially taken out off the cotton production and used for producing alternative crops.
