Year: 1991
Subjects: subject: Farm Management
subject: farm chemicals
subject: farm income
subject: computable general equilibrium
subject: input reduction

description: When farm chemical use is restricted, gross farm income rises, but net income may fall. A 10-sector applied general equilibrium model was used to arrive at this assessment. Compared are a chemical use tax, an input restriction on chemicals, and a farm sales restriction imposed on input suppliers. The tax and sales restrictions reduce net income because of rising costs, while the input restriction holds the potential for raising net farm income.

description: Canadian broiler price responses to increases in US prices either have lessened in magnitude and duration or have been eliminated since Canada's broiler supply management program began in 1979. The authors used monthly vector autoregressions of US and Canadian broiler prices (farm and retail), estimated for periods before and after Canada introduced its broiler supply management program, to arrive at the results. The analysis also demonstrated that data-oriented, tune-series statistical methods are useful in policy analysis when focusing on a policy's dynamic aspects, contrary to the opinion of some researchers.

description: We prove the NP-completeness of the following problem. Given a set $S$ of $n$ slopes and an integer $k\geq 1$, is it possible to draw a complete graph on $k$ vertices in the plane using only slopes from $S$? Equivalently, does there exist a set $K$ of $k$ points in general position such that the slope of every segment between two points of $K$ is in $S$? We then present a polynomial algorithm for this question when $n\leq 2k-c$, conditional on a conjecture of R.E. Jamison. For $n=k$, an algorithm in $\mathcal{O}(n^4)$ was proposed by Wade and Chu. For this case, our algorithm is linear and does not rely on Jamison's conjecture.

Multi-Overlap Simulations for Transitions between Reference Configurations

description: We introduce a new procedure to construct weight factors, which flatten the probability density of the overlap with respect to some pre-defined reference configuration. This allows one to overcome free energy barriers in the overlap variable. Subsequently, we generalize the approach to deal with the overlaps with respect to two reference configurations so that transitions between them are induced. We illustrate our approach by simulations of the brainpeptide Met-enkephalin with the ECEPP/2 energy function using the global-energy-minimum and the second lowest-energy states as reference configurations. The free energy is obtained as functions of the dihedral and the root-mean-square distances from these two configurations. The latter allows one to identify the transition state and to estimate its associated free energy barrier.

Starbursting [O III] emitters and quiescent [C II] emitters in the reionization era

description: Recent observations have successfully detected [O III] $88.3\,{\rm μm}$ and [C II] $157.6\,{\rm μm}$ lines from galaxies in the early Universe with the Atacama Large Millimeter Array (ALMA). Combining cosmological hydrodynamic simulations and radiative transfer calculations, we present relations between the metal line emission and galaxy evolution at $z=6-15$. We find that galaxies during their starburst phases have high [O III] luminosity of $\sim 10^{42}~\rm erg~s^{-1}$. Once supernova feedback quenches star formation, [O III] luminosities rapidly decrease and continue to be zero for $\sim 100\,{\rm Myr}$. The slope of the relation between $\log{(\rm SFR/M_{\odot}~yr^{-1})}$ and $\log{(L_{\rm [O_{III}]}/{\rm L_{\odot}})}$ at $z=6-9$ is 1.03, and 1.43 for $\log{(L_{\rm [C_{II}]}/{\rm L_{\odot}})}$. As gas metallicity increases from sub-solar to solar metallicity by metal enrichment from star formation and feedback, the line luminosity ratio $L_{\rm [O_{III}]} / L_{\rm [C_{II}]}$ decreases from $\sim 10$ to $\sim 1$ because the O/C abundance ratio decreases due to carbon-rich winds from AGB stars and the mass ratio of {\sc H\,ii} to {\sc H\,i} regions decreases due to rapid recombination. Therefore, we suggest that the combination of [O III] and [C II] lines is a good probe to investigate the relative distribution of ionized and neutral gas in high-$z$ galaxies. In addition, we show that deep [C II] observations with a sensitivity of $\sim 10^{-2}~{\rm mJy~arcsec^{-2}}$ can probe the extended neutral gas disks of high-$z$ galaxies.

description: We consider a simple extension of the Standard Model with two singlet scalar fields and three heavy right-handed neutrinos. One of the scalar fields serves as an MeV scale dark matter and its stability is ensured by the introduction of an extra $Z_2$ symmetry. The second scalar (which is even under the $Z_2$ symmetry) generates the mass term of the scalar, contributes to the $3 \rightarrow 2$ annihilation process required for the correct relic density of the dark matter and it also contributes to the leptogenesis. The right-handed neutrinos are responsible for the generation of light neutrino masses through Type-I seesaw mechanism. The decay of the heavy right-handed neutrino can generate the lepton asymmetry which can then be converted to baryon asymmetry through sphaleron transitions.

description: There have been trends for governments to adopt more ‘bottom-up’ approaches on a range of matters including environmental and natural resource management planning. An example is the devolution of public funds to regional natural resource management (NRM) bodies in many areas of Australia. However, there is little empirical evidence available to guide policymakers in determining best value arrangements and strategic investments for building a region’s ‘collaborative advantage’. An economic appraisal of engagement processes might focus on evaluating whether the benefits of particular governance arrangements outweigh the costs. The identification and assessment of many of the costs and benefits associated with various engagement processes is not an easy task. Many of the costs can be classified as transaction costs, where the costs of collaboration and engagement in a process can be likened to the search, negotiation, monitoring, and enforcement costs familiar from market transactions. In a marginal analysis setting, the question is whether the costs incurred from an alternative governance arrangement are justified when the benefits are considered. The benefits of a more participatory and inclusive governance arrangement might include improvements to resource allocation, achieving changes in attitudes to land management practices, reduction in conflict, and development of ‘administrative capital’. These benefits are difficult to estimate, although non-market valuation techniques can offer some insights into the magnitude of such benefits. An outline of an approach to evaluate the benefits and costs of a Devolved Grants program administered by the Fitzroy Basin Association (FBA) regional natural resource management (NRM) body in Central Queensland is presented in this paper.
Spin Waves in Antiferromagnetic Spin Chains with Long Range Interactions

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We study antiferromagnetic spin chains with unfrustrated long-range interactions that decays as a power law with exponent $β$, using the spin wave approximation. We find for sufficiently large spin $S$, the Neel order is stable at T=0 for $β< 3$, and survive up to a finite Neel temperature for $β< 2$, validating the spin-wave approach in these regimes. We estimate the critical values of $S$ and $T$ for the Neel order to be stable. The spin wave spectra are found to be gapless but have non-linear momentum dependence at long wave length, which is responsible for the suppression of quantum and thermal fluctuations and stabilizing the Neel state. We also show that for $β\le 1$ and for a large but finite-size system size $L$, the excitation gap of the system approaches zero slower than $L^{-1}$, a behavior that is in contrast to the Lieb-Schulz-Mattis theorem.

description: The paper examines the relationship between the innovator’s patenting and patent breadth decisions as well as how these two decisions affect, and are affected by, the innovator’s ability to enforce her patent rights. An important feature of the model is that the entrant may be able, by his choice of location in product space, to affect the innovator’s decision to defend her patent. An interesting finding of the paper is that the innovator might find it optimal to patent her innovation even when she chooses to not defend her patent by invoking a trial when patent infringement occurs. The paper also shows that, in most cases, the greater is the entrant’s R&D effectiveness, the smaller is the innovator’s incentive to patent her product. If patenting occurs, however, the greater is R&D effectiveness, the greater is the patent breadth that could be chosen without triggering infringement.

ARGUMENTATION
 The examination of the holotype of C. minima revealed its synonymy with C. petri. The genitalia of this specimen are figured for the first time (Fig. 3 C-D). Both the latero-dorsal and latero-ventral lobes of tergum X have their distal extremities more sclerotized than their basal parts, which are thinner and difficult to distinguish from each other. Gibbs (1973) already noted the relationship of C. petri to C. intexta, C. cognata and C. lufirae. Besides the differences in tergum X, C. minima differs from other species of the group in the absence of a process on the inner face of the inferior appendage and the reticulated appearance of the prolongations of the phallic apparatus.

description: A quantum degenerate, dilute gas mixture of bosonic and fermionic atoms was produced using 87Rb and 40K. The onset of degeneracy was confirmed by observing the spatial distribution of the gases after time-of-flight expansion. Further, the magnitude of the interspecies scattering length between the doubly spin polarized states of 87Rb and 40K, |a_RbK|, was determined from cross-dimensional thermal relaxation. The uncertainty in this collision measurement was greatly reduced by taking the ratio of interspecies and intraspecies relaxation rates, yielding |a_RbK| = 250 +/- 30 a_0, which is a lower value than what was reported in [M. Modugno et al., Phys. Rev. A 68, 043626 (2003)]. Using the value for |a_RbK| reported here, current T=0 theory would predict a threshold for mechanical instability that is inconsistent with the experimentally observed onset for sudden loss of fermions in [G. Modugno et al., Science 297, 2240 (2002)].

description: Grain is China’s most significant agricultural product, its output being the most watched indicator by government officials, traders and researchers both inside and outside China. This paper looks into China’s grain production trends in the recent decade and how the grains industry has responded to the WTO accession. It examines changes in total grain output, grain crop composition, regional distribution of grain production, and also changes in production technologies and costs. The paper concludes by addressing a number of emerging issues that are likely to affect future grain production in China.

description: The following work aims to research and explain the choices made in the field of military equipment and made Greece after the Asia Minor Disaster to the dictatorship of Metaxas and more specifically until the declaration of war on October 28, 1940. These elements in a job have the main purpose of finding and explaining mainly through the policy of the country its military equipment. The interwar period in Greece until the Italian Greek war was influenced by important political decisions and by personalities, such as E. Venizelos, Th. Pangalos and I. Metaxas. The main contributors to the analysis and explanation of the country's military equipment will be the economy, plans and decisions of the country's political and, of course, military personnel. The latter combined with international developments in economy, politics and of course international relations, as inter -war Europe was preparing for a new war.

description: We calculate spectral functions of the relativistic $O(4)$ model from real-time lattice simulations in classical-statistical field theory. While in the low and high temperature phase of the model, the spectral functions of longitudinal $(σ)$ and transverse $(π)$ modes are well described by relativistic quasi-particle peaks, we find a highly non-trivial behavior of the spectral functions in the cross over region, where additional structures appear. Similarly, we observe a significant broadening of the quasi-particle peaks, when the amount explicit $O(4)$ symmetry breaking is reduced. We further demonstrate that in the vicinity of the $O(4)$ critical point, the spectral functions develop an infrared power law associated with the critical dynamics, and comment on the extraction of the dynamical critical exponent $z$ from our simulations.

Electrodynamics of black hole magnetospheres

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: Numerical simulations combined with simple analytical arguments are used to reach a number of important conclusions on the nature of the Blandford-Znajek mechanism. We show that, just like in the Penrose mechanism and in the MHD models of Punsly and Coroniti, the key role in this mechanism is played by the black hole ergosphere. The poloidal currents are driven by the gravitationally induced electric field which cannot be screened within the ergosphere by any static distribution of the electric charge of locally created pair plasma. Contrary to what is expected in the Membrane paradigm, the energy and angular momentum are extracted not only along the magnetic field lines penetrating the event horizon but along all field lines penetrating the ergosphere. In dipolar magnetic configurations symmetric relative to the equatorial plane the force-free approximation breaks down within the ergosphere where a strong current sheet develops along the equatorial plane. This current sheet supplies energy and angular momentum at infinity to the surrounding force-free magnetosphere. The Blandford-Znajek monopole solution is found to be asymptotically stable and causal. The so-called horizon boundary condition of Znajek is shown to be a regularity condition at fast critical surface.

description: We investigate the dynamics of a particle moving randomly along a disordered hetero-polymer subjected to rapid conformational changes which induce superdiffusive motion in chemical coordinates. We study the antagonistic interplay between the enhanced diffusion and the quenched disorder. The dispersion speed exhibits universal behavior independent of the folding statistics. On the other hand it is strongly affected by the structure of the disordered potential. The results may serve as a reference point for a number of translocation phenomena observed in biological cells, such as protein dynamics on DNA strands.

description: We consider the problem of reward learning for temporally extended tasks. For reward learning, inverse reinforcement learning (IRL) is a widely used paradigm. Given a Markov decision process (MDP) and a set of demonstrations for a task, IRL learns a reward function that assigns a real-valued reward to each state of the MDP. However, for temporally extended tasks, the underlying reward function may not be expressible as a function of individual states of the MDP. Instead, the history of visited states may need to be considered to determine the reward at the current state. To address this issue, we propose an iterative algorithm to learn a reward function for temporally extended tasks. At each iteration, the algorithm alternates between two modules, a task inference module that infers the underlying task structure and a reward learning module that uses the inferred task structure to learn a reward function. The task inference module produces a series of queries, where each query is a sequence of subgoals. The demonstrator provides a binary response to each query by attempting to execute it in the environment and observing the environment's feedback. After the queries are answered, the task inference module returns an automaton encoding its current hypothesis of the task structure. The reward learning module augments the state space of the MDP with the states of the automaton. The module then proceeds to learn a reward function over the augmented state space using a novel deep maximum entropy IRL algorithm. This iterative process continues until it learns a reward function with satisfactory performance. The experiments show that the proposed algorithm significantly outperforms several IRL baselines on temporally extended tasks.

description: Groundwater has been a relatively safe water source and associated with a series of global pressing issues. It can, however, be vulnerable to pathogen contamination and exhibit risks to public health. While groundwater has often been considered a relatively closed ecosystem, it is important to understand the transport of pathogens into and within groundwater and groundwater-dependent ecosystems in the context of their physiological characteristics, soil/sediment texture, hydrogeological and climatic conditions. The rapid progress in monitoring and modeling tools in recent years has facilitated the detection of pathogens and the prediction of their migration in groundwater, which aids the surveillance and remediation of health-related risks. This review aims to provide an updated understanding about groundwater pathogens, their impacts on human health, surveillance, risk assessment, and remediation strategies in the context of the global environment and climate changes. The challenges and perspectives in protecting groundwater biosafety are also discussed.

We employ the physical consideration, the degenerate perturbation theory, the level spectroscopy analysis of the numerical diagonalization data obtained by the Lanczos method and also the density matrix renormalization group (DMRG) method. We investigate the mechanisms of the magnetization plateaux at $M=M_s/3$ and $M=(2/3)M_s$, and also show the precise phase diagrams on the $(J_2/J_1, J_3/J_1)$ plane concerning with these magnetization plateaux, where $M=\sum_{l=1}^{N} S_l^z$ and $M_s$ is the saturation magnetization. We also calculate the magnetization curves and the magnetization phase diagrams by means of the DMRG method.

description: We investigate the valence transition in three-dimensional topological Kondo insulator through slave-boson analysis of periodic Anderson model. By including the effect of intra-atomic Coulomb correlation $U_{fc}$ between conduction and local electrons, we find a first-order valence transition from Kondo region to mixed valence upon ascending of local level above a critical $U_{fc}$, and this valence transition usually occurs very close to or simultaneously with a topological transition. Near the parameter region of zero-temperature valence transition, rise of temperature can generate a thermal valence transition from mixed valence to Kondo region, accompanied by a first-order topological transition. Remarkably, above a critical $U_{fc}$ which is considerable smaller than that generating paramagnetic valence transition, the original continuous antiferromagnetic transition is shifted to first order one, at which a discontinuous valence shift takes place. Upon increased $U_{fc}$, the paramagnetic valence transition approaches then converges with the first-order antiferromagnetic transition, leaving an significant valence shift on the magnetic boundary. The continuous antiferromagnetic transition, first-order antiferromagnetic transition, paramagnetic valence transition and topological transitions are all summarized in a global phase diagram. Our proposed exotic transition processes can help to understand the thermal valence variation as well as the valence shift around the pressure-induced magnetic transition in topological Kondo insulator candidates and in other heavy-fermion systems.

description: The status of the `BRST-invariant' condensate of mass dimension two in QCD is explained. The condensate is only invariant under an `on-shell' BRST symmetry which includes a partial gauge-fixing. The on-shell BRST symmetry represents the residual gauge symmetry under gauge transformations which preserve the partial gauge fixing. The gauge-invariant operators which correspond to the BRST-invariant condensate are identified in the Lorentz and maximal Abelian gauges and are shown to be invariant under the residual gauge transformations.

description: FinTech can significantly improve the efficiency of financial services, improve the transparency of the financial system, and promote economic growth. However, as a “disruptive innovation,” it also brings more uncertainty and potential risks. In recent years, China's FinTech industry has achieved remarkable leapfrogging development, but due to the lag or absence of supervision, the hidden risks are prominent, which brings challenges to the existing financial stability. Based on the main participants and external environment of China's FinTech, we select 11 first-level indicators and 30 s-level indicators in five categories and use the principal component analysis (PCA) to construct a comprehensive stress index of Fintech risk that conforms to the actual characteristics of China. Based on monthly data from 2010 to 2021, we use the MS-VAR model and ARIMA model to empirically analyze and predict the risks of FinTech in China. Our result indicates that, in terms of duration, the low-to-medium risk state of China's FinTech persists for a relatively long time, with overall risks being controllable. From the perspective of external shocks, macroeconomic factors can influence financial risks, which in turn affect the size of FinTech risks. As for the development trend, in the next five years, China's FinTech will mainly remain in a low-to-medium risk state, with high-risk fluctuations only occurring in a few time periods. The research significance of this paper is reflected in the following aspects: First, this paper constructs a Fintech risk stress index that conforms to the actual characteristics of China and profoundly analyzes the risk level and future trend of China's Fintech, which is conducive to deepening the theoretical research on Fintech risk early warning; Secondly, the study of this paper is not only of great significance for promoting the benign development of Fintech in China, but also can provide beneficial schemes for other major countries to prevent Fintech risks and maintain financial stability.

description: We present $HST$ narrow-band near-infrared imaging of Pa$α$ and Pa$β$ emission of 48 local Luminous Infrared Galaxies (LIRGs) from the Great Observatories All-Sky LIRG Survey (GOALS). These data allow us to measure the properties of 810 spatially resolved star-forming regions (59 nuclei and 751 extra-nuclear clumps), and directly compare their properties to those found in both local and high-redshift star-forming galaxies. We find that in LIRGs, the star-forming clumps have radii ranging from $\sim90-900$ pc and star formation rates (SFRs) of $\sim1\times10^{-3}$ to 10 M$_\odot$yr$^{-1}$, with median values for extra-nuclear clumps of 170 pc and 0.03 M$_\odot$yr$^{-1}$. The detected star-forming clumps are young, with a median stellar age of $8.7$ Myrs, and a median stellar mass of $5\times10^{5}$ M$_\odot$. The SFRs span the range of those found in normal local star-forming galaxies to those found in high-redshift star-forming galaxies at $\rm{z}=1-3$. The luminosity function of the LIRG clumps has a flatter slope than found in lower-luminosity, star-forming galaxies, indicating a relative excess of luminous star-forming clumps. In order to predict the possible range of star-forming histories and gas fractions, we compare the star-forming clumps to those measured in the MassiveFIRE high-resolution cosmological simulation. The star-forming clumps in MassiveFIRE cover the same range of SFRs and sizes found in the local LIRGs and have total gas fractions that extend from 10 to 90%. If local LIRGs are similar to these simulated galaxies, we expect future observations with ALMA will find a large range of gas fractions, and corresponding star formation efficiencies, among the star-forming clumps in LIRGs.

description: A Lorentz-noninvariant modification of the kinematic dispersion law was proposed in [hep-th/0211237], claimed to be derivable from from q-deformed noncommutative theory, and argued to evade ultrahigh energy threshold anomalies (trans-GKZ-cutoff cosmic rays and TeV-photons) by raising the respective thresholds. It is pointed out that such dispersion laws do not follow from deformed oscillator systems, and the proposed dispersion law is invalidated by tachyonic propagation, as well as photon instability, in addition to the process considered.

description: The paper investigates Halevi’s theory of divine attributes as an example of the transfer of knowledge from the Classical Arabic philosophy to Judeo-Arabic philosophy. To this end, the depiction of divine attributes in Al-Ghazālī’s Al-Iqtiṣād fī al-i‛tiqād is compared to that offered by Halevi in the Sefer ha-Kuzari. The initial extended delineation of Al-Ghazālī’s account constitutes the background for the investigation of Halevi’s approach, in order to facilitate the comparison of both. The investigation of the discussion of divine attributes in the works of both authors does not only serve to demonstrate the similarities of both when it comes to their indebtedness towards and their criticism of the Neoplatonic-Aristotelian philosophical tradition. It also serves to illustrate their understanding of metaphorical and figurative language. Furthermore, the paper aims to show what parts of Al-Ghazālī’s thinking became transformed in this transfer process due to the different religious context.
