description: The objective is to present the economic impact of producers adopting Bt cotton and the rapid diffusion on the main producing countries: USA, China and India. The existing literature about this type of transgenic crop has been revised and the results of different research are presented. Bt cotton varieties have been quickly adopted by the countries in this study. Data show that this technology helps reduce production losses and significantly decrease the use of pesticides, thus saving their cost and the associated labour cost. But the total cost reduction is weak due to the high prices of the seeds incorporating this technology.

Dressing bulk fields in AdS${}_3$

description: We study a set of CFT operators suitable for reconstructing a charged bulk scalar field $ϕ$ in AdS${}_3$ (dual to an operator ${\cal O}$ of dimension $Δ$ in the CFT) in the presence of a conserved spin-$n$ current in the CFT. One has to sum a tower of smeared non-primary scalars $\partial_{+}^{m} J^{(m)}$, where $J^{(m)}$ are primaries with twist $Δ$ and spin $m$ built from ${\cal O}$ and the current. The coefficients of these operators can be fixed by demanding that bulk correlators are well-defined: with a simple ansatz this requirement allows us to calculate bulk correlators directly from the CFT. They are built from specific polynomials of the kinematic invariants up to a freedom to make field redefinitions. To order $1/N$ this procedure captures the dressing of the bulk scalar field by a radial generalized Wilson line.

description: This paper studies a class of information aggregation models which we call “aggregation games.” It departs from the related literature in two main respects: information is aggregated by averaging rather than majority rule, and each player selects from a continuum of reports rather than making a binary choice. Each member of a group receives a private signal, then submits a report to the center, who makes a decision based on the average of these reports. The essence of an aggregation game is that heterogeneous players engage in a “tug-of-war,” as they attempt to manipulate the center’s decision process by mis-reporting their private information. When players have distinct biases, almost of them rationally exaggerate the extent of these biases. The degree of exaggeration increases with the number of players: if the game is sufficiently large, then almost all players exaggerate to the maximum admissible extent, regardless of their individual signals. In the limit, the connection between players’ private information and the outcome of the game is obliterated.

description: Modern hardware platforms, from the very small to the very large, increasingly provide parallel and distributed computing resources for applications to maximise performance. Many applications therefore need to make effective use of tens, hundreds, and even thousands of compute nodes. Computation in such systems is thus inherently concurrent and communication centric. Effectively programming such applications is challenging; performance, correctness, and scalability are difficult to achieve. The development of effective programming methodologies for this increasingly parallel landscape therefore demands exploration and understanding of a wide variety of foundational and practical ideas. The International Workshop on Programming Language Approaches to Concurrency- and Communication-cEntric Software (PLACES) is dedicated to work in this area. The workshop offers a forum for researchers from different fields to exchange new ideas about these challenges to modern and future programming, where concurrency and distribution are the norm rather than a marginal concern. This volume contains the proceedings of the 12th edition of PLACES, which was co-located with ETAPS 2020 in Dublin, Ireland.

description: Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of clinicians’ recast length on child learning during a recast treatment.Method: Twenty-six preschool children were treated for grammatical errors using enhanced conversational recast treatment. Half heard recasts of four or fewer words (Short Recast condition), and half heard recasts of five or more words (Extended Recast condition). Outcome measures included generalization of the treated grammatical form, spontaneous use of these forms, change in mean length of utterances in words, and the number of children in each condition who showed a clinically meaningful response.Results: There was strong evidence of improvements in the use of grammatical forms targeted by the treatment compared with forms that were tracked but not treated. Twenty children (11 in the Short Recast condition and nine in the Extended Recast condition) showed a clinically meaningful response. There was minimal support for the hypothesis that the length of clinician utterance influenced either progress on a grammatical form targeted by the treatment or on the child’s length of utterance in words.Conclusions: The study adds to the evidence for the efficacy of enhanced conversational recast treatment. However, there is little evidence that clinicians need to regulate the length of the recast they provide to children.Supplemental Material S1.

description: In this paper we derive a generic expression, which is valid for scales larger than Hubble radius and contains only the local terms, for the second order curvature perturbations for more than one field, provided the expansion is sourced by the energy density of a single field. As an application, motivated by our previous paper [1], we apply our formalism to two fields during preheating, where the inflaton oscillations are sourced by $λϕ^4$ potential which is governing the expansion of the Universe. A second field $σ$, coupled to the inflaton through $g^2ϕ^2σ^2$, is excited from the vacuum fluctuations. The excited modes of $σ$ amplify the super-Hubble isocurvature perturbations, which seed the second order curvature perturbations to give rise to a significantly large non-Gaussianity. Our results show that within 3 inflaton oscillations for a range of parameters, $1< g^2/λ< 3$, the non-Gaussianity parameter becomes: $f_{NL}\geq {\cal O}(1000)$, which is already ruled out by the current WMAP observation.

description: We study excitonic pairing in nodal fermion systems characterized by a vanishing quasiparticle density of states at the pointlike Fermi surface and a concomitant lack of screening for long-range interactions. By solving the gap equation for the excitonic order parameter, we obtain a critical value of the interaction strength for a variety of power-law interactions and densities of states. We compute the free energy and analyze possible phase transitions, thus shedding further light on the unusual pairing properties of this peculiar class of strongly correlated systems.

description: The setting of a cooperative takes place the moment people holding common interests and wishing to reach common goals, voluntarily unite under a free-adhesion scheme to democratically manage their enterprise taking all benefits and risks involved in cooperative activities. The cooperative organization is structured under ethical principles which distinguish them from other organizations. It is an organization based on democratic theorical principles like solidarity and equalness constituting the bases of their associates´ participation in the decision-making process and which, in its turn, may grant the citizenry formation of its members. In order to understand the cooperative principles a literature review was carried out, ranging authors of several conceptual palletes, including the ideologists of the utopian cooperativism who deal with the solidarity and equality theme as principles of democratic organizations in cooperatives. Next, the analytical categories solidarity and equality were analysed aiming to compare them to the notion given to them by the associates of the Cooperativa Educacional de Viçosa, MG (COEDUCAR). The north point of this paper is the analyses of these theorical concepts in the cooperative´s organizational environment. The methodology used in data-collection was based on qualitative research, by the use of semi-structured surveys, group-dynamic techniques and documental analysis. It was verified that the associates, as they celebrated a contract to the construction of a cooperative, seek to defending both the equality of their rights and solidarity in the development of their interests. On the other hand, they do not put into effect their participation and co-responsibility as for their own business in a practical way.

description: In the framework of the littlest Higgs($LH$) model, we consider the processes $e^{+}e^{-}\toν\barνH^{0}$ and $e^{+}e^{-}\to W^{*}W^{*}ν\barν\toν\barνt\bar{t}$, and calculate the contributions of new particles to the cross sections of these processes in the future high energy $e^{+}e^{-}$ collider($ILC$) with $\sqrt{S}=1TeV$. We find that, with reasonable values of the free parameters, the deviations of the cross sections for the processes $e^{+}e^{-}\toν\barνH^{0}$ from its $SM$ value might be comparable to the future $ILC$ measurement precision. The contributions of the light Higgs boson $H^0 $ to the process $e^{+}e^{-}\to W^{*}W^{*}ν\barν\toν\barνt\bar{t}$ are significant large in all of the parameter space preferred by the electroweak precision data, which might be detected in the future $ILC$ experiments. However, the contributions of the new gauge bosons $B_{H}$ and $Z_{H}$ to this process are very small.

description: The main objective of this paper was to evaluate the technical efficiency in 17 milk production farms in the region of Viçosa, state of Minas Gerais, during the period 1999-2002. These farms have received technical assistance from a program created by the Federal University of Viçosa and Nestlé. The technical efficiency was evaluated through the Data Envelopment Analysis (DEA) technique. The results obtained show that there are still a significant proportion of inefficient farms. It was also observed that the farms have become more homogeneous in their production characteristics which is probably due to the pattern of technical assistance adopted during the period analyzed.

description: We compute the two-loop corrections to the massless quark form factor $γ^* \to q\bar q$ and gluon form factor $H\to gg$ to all orders in the dimensional regularisation parameter $ε=(4-d)/2$. The two-loop contributions to the form factors are reduced to linear combinations of master integrals, which are computed in a closed form, expressed as $Γ$-functions and generalised hypergeometric functions of unit argument. Using the newly developed HypExp-package, these can be expanded to any desired order, yielding Laurent expansions in $ε$. We provide expansions of the form factors to order $ε^2$, as required for ultraviolet renormalisation and infrared factorisation of the three-loop form factors.

description: During the period between 1945 and 1991 the dairy sector was regulated by the State. The price standardization imposed by the government, conducted many times aiming to facilitate adjustments in economy, had serious consequences right after the end of said intervention. The present study tried to understand the process which outlined the conformation of the current institutional structure in this complex, the causes of its maintenance, and the immediate trends which may be envisaged in short and medium terms. There is an absence of public policies devised to account for the incoherences detected in the dairy complex which originate to a large extent in the deliberate loss of the power of regulation by the State and in the liberal orientation taken in the end of the 80s. With the end of the State regulation new mechanisms of support and financing emerged, but those do not go directly under the State actors appreciation. However, the dynamics of the productive restructuring is not yet over. A new phase may be replacing the former, and the actors in the dairy agri-food complex once again should look for solutions for the situations which generate uncertainty and changes, originated in the search for higher competitiveness and professionalization since those proved vital for the permanence of such actors in the formal productive activity.
Signatures of a Noise-Induced Quantum Phase Transition in a Mesoscopic Metal Ring

description: We study a mesoscopic ring with an in-line quantum dot threaded by an Aharonov-Bohm flux. Zero-point fluctuations of the electromagnetic environment capacitively coupled to the ring, with $ω^s$ spectral density, can suppress tunneling through the dot, resulting in a quantum phase transition from an unpolarized to a polarized phase. We show that robust signatures of such a transition can be found in the response of the persistent current in the ring to the external flux as well as to the bias between the dot and the arm. Particular attention is paid to the experimentally relevant cases of ohmic ($s=1$) and subohmic ($s=1/2$) noise.

description: Orbital Hall effect (OHE) is the phenomenon of transverse flow of orbital moment in presence of an applied electric field. Solids with broken inversion symmetry are expected to exhibit a strong OHE due to the presence of an intrinsic orbital moment at individual momentum points in the Brillouin zone, which in presence of an applied electric field, flows in different directions causing a net orbital Hall current. Here we provide a comprehensive understanding of the effect and its tunability in the monolayer 2D transition metal dichalcogenides (TMDCs). Both metallic and insulating TMDCs are investigated from full density-functional calculations, effective $d$-band tight-binding models, as well as a minimal four-band model for the valley points that captures the key physics of the system. For the tuning of the OHE, we examine the role of hole doping as well as the change in the band parameters, which, e. g., can be controlled by strain. We demonstrate that the OHE is a more fundamental effect than the spin Hall effect (SHE), with the momentum-space orbital moments inducing a spin moment in the presence of the spin-orbit coupling, leading to the SHE. The physics of the OHE, described here, is relevant for 2D materials with broken inversion symmetry in general, even beyond the TMDCs, providing a broad platform for future research.

description: With this article the intention is to add to the Transaction Cost Analysis empirical discussions. It introduces a model that aims to graphically represent transaction arrangements. The proposed model was empirically tested in the Brazilian fruit export sector. Six different fruit were used as the basis for the investigation: melons, grapes, mangoes, papayas, oranges and apples. These are the six most exported fruit produced in Brazil. Two distinct research techniques were used in the investigation: secondary data analysis and interviews. The focal aim of the secondary data research was the characterisation and comparison of the production and export sequences of the six most exported Brazilian fruit types. The content of the semi-structured interview questions was determined based on the literature review of Transaction Cost Analysis and the international fruit trade. The questions were carefully chosen to reveal the factors which are determinant for the configuration of transaction arrangements in the fruit trade. The Graphical Representation of Transactions successfully disclosed the three main types of arrangements used by Brazilian fruit exporters. These arrangements are : Integrated Production-Export Transaction Arrangement, Export Agents Transaction Arrangement and the Integrated Multinational Transaction Arrangement. The graphical model makes the process of categorising organisations according to their behaviour more precise. By clearly describing the technical activities performed by an organisation it is possible to assess its role in a specific sector.

description: Particle spin polarization is known to be linked both to rotation (angular momentum) and magnetization of a many particle system. However, in the most common formulation of relativistic kinetic theory, the spin degrees of freedom appear only as degeneracy factors multiplying phase-space distributions. Thus, it is important to develop theoretical tools that allow to make predictions regarding the spin polarization of particles, which can be directly confronted with experimental data. Herein, we discuss a link between the relativistic spin tensor and particle spin polarization, and elucidate the connections between the Wigner function and average polarization. Our results may be useful for theoretical interpretation of heavy-ion data on spin polarization of the produced hadrons.

description: We investigate theoretically donor-based charge qubit operation driven by external electric fields. The basic physics of the problem is presented by considering a single electron bound to a shallow-donor pair in GaAs: This system is closely related to the homopolar molecular ion H_2^+. In the case of Si, heteropolar configurations such as PSb^+ pairs are also considered. For both homopolar and heteropolar pairs, the multivalley conduction band structure of Si leads to short-period oscillations of the tunnel-coupling strength as a function of the inter-donor relative position. However, for any fixed donor configuration, the response of the bound electron to a uniform electric field in Si is qualitatively very similar to the GaAs case, with no valley quantum interference-related effects, leading to the conclusion that electric field driven coherent manipulation of donor-based charge qubits is feasible in semiconductors.

description: We revisit the indentation of a thin solid sheet of size $R_{sheet}$ suspended on a circular hole of radius $R \ll R_{sheet}$ in a smooth rigid substrate, addressing the effects of boundary conditions at the hole's edge. Introducing a basic theoretical model for the Van-der-Waals (VdW) sheet-substrate attraction, we demonstrate the dramatic effect of replacing the clamping condition (Schwerin model) with a sliding condition, whereby the supported part of the sheet is allowed to slide towards the indenter and relax the induced hoop compression through angstrom-scale deflections from the thermodynamic equilibrium (determined by the VdW potential). We highlight the possibility that the indentation force $F$ may not exhibit the commonly anticipated cubic dependence on the indentation depth ($F\propto δ^3$), in which the proportionality constant is governed by the sheet's stretching modulus and the hole's radius $R$, but rather a {\emph{pseduo-linear}} response, $F \propto δ$, whereby the proportionality constant is governed by the bending modulus, the VdW attraction, and the sheet's size $R_{sheet} \gg R$.

description: Simulations of the collapse and fragmentation of turbulent molecular clouds and dense young clusters show that encounters between disc-surrounded stars are relatively common events which should significantly influence the resulting disc structure. In turn this should alter the accretion rate of disc matter onto the star and the conditions under which planet formation occurs. Although the effects of star-disc encounters have been previously investigated, very little is known about encounters where both stars are surrounded by discs. In this paper encounters of such disc-disc systems are studied quantitatively. It is found that for low-mass discs ($M_D$= 0.01 $M_\sun$) the results from star-disc encounters can be straightforwardly generalized to disc-disc encounters as long as there is no mass transport between the discs. Differences to star-disc encounters occur naturally where significant amounts of matter are transported between the discs. In this case it is found that although the mass distribution does not change significantly, matter caught onto highly eccentric orbits is transported surprisingly far inside the disc. The captured mass partly replenishes the disc, but has a much lower angular momentum. This can lead to a reduction of the angular momentum in the entire disc and thus considerably increased accretion shortly after the encounter as well as in the long term.

description: Supersymmetric U(Nc) gauge theory with Nf massive hypermultiplets in the fundamental representation is given by the brane configuration made of Nc fractional Dp-branes stuck at the Z_2 orbifold singularity on Nf separated D(p+4)-branes. We show that non-Abelian walls in this theory are realized as kinky fractional Dp-branes interpolating between D(p+4)-branes. Wall solutions and their duality between Nc and Nf - Nc imply extensions of the s-rule and the Hanany-Witten effect in brane dynamics. We also find that the reconnection of fractional D-branes occurs in this system. Diverse phenomena in non-Abelian walls found in field theory can be understood very easily by this brane configuration.

description: Recent observations of giant flares from soft gamma-ray repeaters have exhibited multiple 25-150 Hz oscillations. Frequencies in this range are expected for toroidal shear waves in a neutron star (NS) crust, lending support to Duncan's proposal that such modes may be excited in these events. This motivates a reassessment of how these waves reflect the NS structure and what role the magnetic field plays in setting their frequencies. We calculate the eigenfrequencies and eigenfunctions of toroidal oscillations for a realistic NS crust, including a vertical magnetic field at magnetar strengths ($B\sim10^{14}-10^{15} {\rm G}$). The lowest radial-order mode has a red-shifted frequency of $\approx28 {\rm Hz}[l(l+1)/6]^{1/2}$, with the prefactor depending on the NS's mass and radius, and its crust's depth and composition. This mode is independent of the magnetic field for $B\lesssim4\times10^{15} {\rm G}$, a limit much greater than the inferred dipole magnetic fields for these objects. Though this is a good fit to the observed oscillations, only rather loose constraints can be made for the NSs' properties because all that can be fit is this prefactor (a single parameter). Modes with shorter radial wavelengths are more sensitive to the magnetic field starting at $B\sim2\times10^{14} {\rm G}$ and have higher frequencies (600-2000 Hz). The discovery of these modes, coupled with the oscillations observed thus far, would provide a powerful probe to the NS crustal structure.

Evaluation of neuromuscular control after anterior cruciate ligament rupture - Development of objective criteria to assess sensorimotor competence

description: A rupture of the anterior cruciate ligament (ACL) is a frequent injury in physically active individuals with young women at highest risk. It is known that ACL ruptures induce altered knee biomechanics - these changes are referred to neuromuscular adaptations due to altered sensorimotor control. Regardless of treatment (surgical reconstruction or rehabilitation alone), the consequences after ACL rupture are often poor knee-related quality of life, reduced knee function, or even posttraumatic knee osteoarthritis in the long run. Furthermore, the re-injury rates sum up to 20 – 40% which is unacceptably high. Even though almost all patients return to sports (RTS), not everyone achieves pre-injury levels of physical activity. To judge upon readiness for RTS, physical performance tests such as strength and hop tests are used to assess neuromuscular control. However, most of these tests lack validity. In addition, the outcomes do not adequately reflect the level of neuromuscular control needed for a safe RTS as they are not close enough to muscle physiology. Moreover, evidence concerning neuromuscular control for functional stability during activities of daily life (ADL) or in doing sports is sparse. Therefore, this PhD project aimed to explore neuromuscular control of knee stabilizing muscles in patients with unilateral ACL rupture, in the acute phase and after one year, RTS respectively. 
The research includes a systematic literature review and three cross-sectional studies investigating differences in neuromuscular control regarding sex, treatment modality and injured versus non-involved leg. 
The systematic literature review provides outcomes of electromyography (EMG) assessing neuromuscular control of the knee during ADL and sports. So far, none of the included research projects used EMG outcomes to judge upon readiness to RTS. 
In the cross-sectional studies, patients were assessed either pre-operatively within three weeks after ACL rupture, or one year after reconstruction, rehabilitation respectively. Healthy, matched participants served as control group. Neuromuscular control of quadriceps and hamstring muscles was measured by EMG during stair walking (functional task, ADL) and during anterior tibial translation (reflex activity, simulation of injury mechanism). 
The findings from this PhD thesis emphasize the need for more specific rehabilitation protocols to focus on restoring neuromuscular control of both legs to the level of healthy controls, and to consider sex- and treatment-specific aspects in patients after ACL rupture.
The thesis concludes by suggesting future research including long-term follow up, exploring the potential role of prehabilitation, and using EMG-related outcomes to assess neuromuscular control in people after ACL rupture.

description: A pulsed-gate technique with charge sensing is used to measure the singlet-triplet relaxation time for nearly-degenerate spin states in a two-electron double quantum dot. Transitions from the (1,1) charge occupancy state to the (0,2) state, measured as a function of pulse cycle duration and magnetic field, allow the (1,1) singlet-triplet relaxation time (~70 microseconds) and the (0,2) singlet-triplet splitting to be measured. The use of charge sensing rather than current measurement allows long relaxation times to be readily probed.

Proteins that interact with ubiquitin-conjugating enzyme 2, UBC-2, in the nematode Caenorhabditis elegans
Creators: name: Groombridge, Marieke Tina
Publisher: name: University of British Columbia
Year: 2009

description: A major route for protein degradation occurs via the ubiquitin-proteasome pathway. Proteins are targeted for destruction by the proteasome through covalent ubiquitin attachment. This tagging system involves the concerted action of an ubiquitin-activating enzyme (El), an ubiquitin-conjugating enzyme (E2), and an ubiquitin ligase (E3), with the latter two being involved in achieving target specificity. UBC-2, an essential E2 in the nematode C. elegans, is a functional homolog of Saccharomyces cerevisiae UBC4, a member of a branch of ubiquitin-conjugating enzymes required for the degradation of short-lived and abnormal proteins. In order to identify proteins that interact with UBC-2, a yeast two-hybrid analysis was employed. Putative TJBC-2 interacting proteins identified include: a ubiquitin-like budding yeast DSK2 ortholog referred to as DSK-2, two RING finger proteins, a protein containing a FYVE domain, a calcium ATPase called MCA-1, and ubiquitin. Since DSK-2 represented 60% of the putative interactors isolated from the screen, this project focused on the interaction of UBC-2 and DSK-2, and demonstrated a novel interaction between an E2 and an ubiquitin-domain protein (UDP) in vitro. The ability of DSK-2 to bind polyubiquitin and itself was also demonstrated. RNA interference (RNAi) was employed in an attempt to determine the biological function of UBC-2 interacting proteins in vivo. RNAi with mca-1 produced a subtle body shortening phenotype, although genes encoding UBC-2 interacting proteins appear to be non-essential.

description: This article analyzes the effect of the aging and the retirements in the Brazilian rural scene, which is a question of most importance for the current days, since the relative participation of the aging group in the total set of the Brazilian population is increasing. Thus, there exists a concern with the future of the Social Security sot that it must pass through reforms. Hence, the objective of this paper is to raise elements for the discussion on the importance of the social security in the agricultural sector, since it passes through significant demographic changes. With a sufficiently fragmented history, since the years of the Empire, the Social Security has been extending several segments of society, being one of the most important forms of inclusion of the agricultural workers. Since 1991, agricultural workers have been covered by the General Regimen of the Social Security, which constitutes a great landmark in the history of the institution. With the incorporation of women in this benefit, new rights have been set, since aged women are majority in the field. The number of retirees due to aging the rural areas. This is an evidence of the aging process of the rural population and a better income redistribution among the elderly households). The field, that in the past depended basically on the income of the agricultural production, now counts on this extra alternative of income, reason for why the phenomenon of aging of the Brazilian population, specifically in the agricultural environment, brings the necessity of adjusting policies to the sector, so that the concession of these social security will not be threatened in the future.

description: We develop a systematic approach to construct the one-loop ${\cal N}=4$ SYM effective action depending on both ${\cal N}=2$ vector multiplet and hypermultiplet background fields. Beginning with the formulation of ${\cal N}=4$ SYM theory in terms of ${\cal N}=2$ harmonic superfields, we construct the one-loop effective action using the covariant ${\cal N}=2$ harmonic supergraphs and calculate it in ${\cal N}=2$ harmonic superfield form for constant Abelian strength $F_{mn}$ and corresponding constant hypermultiplet fields. The hypermultiplet-dependent effective action is derived and given by integral over the analytic subspace of harmonic superspace. We show that each term in the Schwinger-De Witt expansion of the low-energy effective action is written as integral over full ${\cal N}=2$ superspace.
