description: We present a comprehensive multi-frequency catalogue of radio sources behind the Large Magellanic Cloud between 0.2 and 20 GHz, gathered from a combination of new and legacy radio continuum surveys. This catalogue covers an area of $\sim$144~deg$^2$ at angular resolutions from 45 arcsec to $\sim$3 arcmin. We find 6434 discrete radio sources in total, of which 3789 are detected at two or more radio frequencies. We estimate the median spectral index ($α$; where $S_{v}\simν^α$) of $α= -0.89 $ and mean of $-0.88 \pm 0.48$ for 3636 sources detected exclusively at two frequencies (0.843 and 1.384 GHz) with similar resolution (FWHM $\sim$40-45 arcsec). The large frequency range of the surveys makes it an effective tool to investigate Gigahertz Peak Spectrum (GPS), Compact Steep Spectrum (CSS) and Infrared Faint Radio sources populations within our sample. We find 10 GPS candidates with peak frequencies near 5 GHz, from which we estimate their linear size. 1866 sources from our catalogue are (CSS) candidates with $α0.5$. We found optical counterparts for 343 of the radio continuum sources, of which 128have a redshift measurement. Finally, we investigate the population of 123 Infrared Faint Radio Sources (IFRSs) found in this study.

Farming Cooperations
Creators: name: Svendsen, Soren
Publisher: name: Unknown
Year: 1997
Subjects: Agribusiness

description: In Denmark farming cooperations have been studied during the last six years. Six years ago the phenomenon was hardly known in Denmark. Therefore no theory has been developed about cooperations in the agriculture until now. This study deals with farming cooperations in Denmark. The objective of the study has been to develop a theoretical basis for farming cooperations and after that obtain experiences from established farmers' cooperations and see whether the objectives of the farmers have been fulfilled. An increasing interest in establishing cooperations has developed in recent years in Denmark because of obvious advantages such as saving money, more leisure and less business risk. But there are difficulties too in collaboration between neighboring farms. Farmers now have to agree about decisions with other farmers. They must hold frequent meetings and they must exchange information. They cannot just do what they want any more. The participants have to act like other employees in some ways. Moreover there are some conditions which must be fulfilled in order to make the cooperation a success. The participants must have confidence in each other. They must be able to collaborate, they must like each other in some way and the distance between them in miles must not be too far.
The very interesting question is whether the advantages more than compensate for the disadvantages. Or put in another way: Has the utility of the farmers raised by joining a cooperation. That is what this study is about.

description: The number of extensive beef farms declared bankrupt in the cattle grazing regions of South Africa increased from 10 farms in 1970 to 35 farms in 1994. Bankruptcies rose in particular from the early 1980’s onwards, against a background of drought and rising interest rates. Ordinary least squares regression and principal component analysis show that bankruptcies increased with lower real beef producer prices, lower annual rainfall and higher real stockfeed and transport subsidies (business risk factors). Higher aggregate farm leverage and real interest rates (financial risk factors) also led to more bankruptcies amongst extensive beef farmers. All variables were related to bankruptcy with a time lag, implying that the bankruptcy process is dynamic.

Farm Management Challenges Posed by Recent Deregulation of Maize Grain Marketing in South Africa

Subjects: Farm Management
Agricultural and Food Policy

description: Recent changes to the highly regulated maize grain marketing system in South Africa are analysed to asses the management implications for local maize farmers. Between 1944/45 and 1994/95, the Maize Board and its agents (co-operatives) were the single channel for maize grain marketing. Statutory single channel marketing and storage control were abolishedfrom May 1995 and "free’' trade within the domestic market was permitted (the Maize Board remained the sole exporter). Single channel import control on maize exercised by the Board was also replaced by import tariffs. These changes have increased price risk for local maize producers who have responded in the short-run by using forward contracting, electronic marketing andfutures contracts. In the longer run, attempts to reduce maize grain storage costs through more use of on-farm bunker storage, plastic tunnels, steel and concrete silos and the leasing of co-operative silo space are likely. Increased import competition could lead to changes in enterprise mixes, particularly in coastal areas which will probably import more maize.

description: Different theoretical and phenomenological aspects of the Minimal and Nonminimal Walking Technicolor theories have recently been studied. The goal here is to make the models ready for collider phenomenology. We do this by constructing the low energy effective theory containing scalars, pseudoscalars, vector mesons and other fields predicted by the minimal walking theory. We construct their self-interactions and interactions with standard model fields. Using the Weinberg sum rules, opportunely modified to take into account the walking behavior of the underlying gauge theory, we find interesting relations for the spin-one spectrum. We derive the electroweak parameters using the newly constructed effective theory and compare the results with the underlying gauge theory. Our analysis is sufficiently general such that the resulting model can be used to represent a generic walking technicolor theory not at odds with precision data.

description: We compare the constraints from two (2019 and 2021) compilations of HII starburst galaxy (HIIG) data and test the model-independence of quasar angular size (QSO) data using six spatially flat and non-flat cosmological models. We find that the new 2021 compilation of HIIG data generally provides tighter constraints and prefers lower values of cosmological parameters than those from the 2019 HIIG data. QSO data by themselves give relatively model-independent constraints on the characteristic linear size, $l_{\rm m}$, of the QSOs within the sample. We also use Hubble parameter ($H(z)$), baryon acoustic oscillation (BAO), Pantheon Type Ia supernova (SN Ia) apparent magnitude (SN-Pantheon), and DES-3yr binned SN Ia apparent magnitude (SN-DES) measurements to perform joint analyses with HIIG and QSO angular size data, since their constraints are not mutually inconsistent within the six cosmological models we study. A joint analysis of $H(z)$, BAO, SN-Pantheon, SN-DES, QSO, and the newest compilation of HIIG data provides almost model-independent summary estimates of the Hubble constant, $H_0=69.7\pm1.2\ \rm{km \ s^{-1} \ Mpc^{-1}}$, the non-relativistic matter density parameter, $Ω_{\rm m_0}=0.293\pm0.021$, and $l_{\rm m}=10.93\pm0.25$ pc.

Globalisation of the Agricultural Sector in the 21st Century: Development, Barriers and Consequences
Creators: name: Hansen, Henning Otte
Publisher: name: Unknown
Year: 1997
Subjects: International Relations/Trade

description: The international trade and diversion of resources within agriculture is relatively low due to market, political and technical barriers. These barriers will be of less importance in the next decade, and this will accelerate globalisation. Various studies have estimated and quantified the effect of liberalization on international trade. It is shown that agricultural international trade will increase significantly as a result of the present and future liberalization of the agricultural policy. Still, there are barriers to agricultural globalisation, but often farmers must overcome these obstacles in order to obtain the competitive advantage of globalisation. Economies of scale, market growth and access to raw matrerials are major motives. Further on, globalisation is recognized to be a very strategic challenge by major food industries, and a trend towards transnational corporations is appearing.

Will Farmers Cash in on 'Green Money'? A Danish Case Study Approach to the CAP Accompanying Measures

Publisher: name: Unknown
Year: 1997
Subjects: Agricultural and Food Policy

description: The paper studies the Danish Environmentally Beneficial Farming programme, introduced as implementation of EU Directive 92/2078 (part of the “accompanying measures” of the CAP reform). A case study approach has been used to look more closely at the qualitative aspects of the uptake of the measures in this programme amongst Danish farmers in the designated Especially Sensitive Agricultural Areas (ESAA). Two study areas were chosen, and personal and focus group interviews undertaken to elicit farmers’ own experiences and views on these voluntary environmental measures, as well as the experiences of the administrative authorities and advisory services. The results indicate that a greater emphasis is needed on methods and content of information. Further, the ‘provider’s cost’ approach to the payment schemes of the measures may not necessarily be the most efficient or effective. A stronger focus on payment and priorities in relation to environmental effects, and the communication of the environmental significance of these measures, should give better results from the programme.

description: We propose a special cavity design that is constructed by terminating a one-dimensional waveguide with a perfect mirror at one end and doping a two-level atom at the other. We show that this atom plays the intrinsic role of a semi-transparent mirror for single photon transports such that quasi-normal modes (QNM's) emerge spontaneously in the cavity system. This atomic mirror has its reflection coefficient tunable through its level spacing and its coupling to the cavity field, for which the cavity system can be regarded as a two-end resonator with a continuously tunable leakage. The overall investigation predicts the existence of quasi-bound states in the waveguide continuum. Solid state implementations based on a dc-SQUID circuit and a defected line resonator embedded in a photonic crystal are illustrated to show the experimental accessibility of the generic model.

The effective potential for the Coleman-Weinberg model
Creators: name: Bates, Ross Taylor
Publisher: name: University of British Columbia
Year: 2010

description: Gauge theories which have a phase transition could be useful in the study of quark confinement. One of the simplest theories containing a phase transition is the Coleman-Weinberg model of massless scalar electrodynamics. The calculation of the renormalized effective potential for the Coleman-Weinberg model is reviewed in detail using the path integral formalism. The effective potential is evaluated at the one-loop level to show that the model exhibits dynamical symmetry breaking at zero temperature. The divergent parts are shown to be renormalizable to two-loop order. The temperature dependence of the effective potential is then calculated to one-loop in order to demonstrate that the symmetry of the model is restored at high temperature, indicating a phase transition. Finally, for models which exhibit this type of behaviour, applications to SU(n) theories of quarks are discussed.

description: This is a review of Lee Smolin's "The Trouble with Physics". The main gist of the review is that the physics of the past three decades has been rich with new discoveries in a large number of domains. The Standard Model, while providing a successful framework for the electroweak and strong interactions still needs to be developed further to fully account fot the mass of strong interaction data collected over the decades. A multitude of new phenomena have been discovered however, or predicted theoretically, in the physics of very low temperatures (e.g. fractional Hall effect, Bose-Einstein condensation) and quantum macroscopic effects (liquid crystals, high temperature superconductivity), some of which remain to be fully explained. Therefore if there is any "Trouble with Physics", as implied by the author of this book, it mainly concerns speculative work on Superstring theory, which may or may not turn out to agree with the results of observation. The subject as a whole does not appear to be in trouble.

Evaluating NISA as a Stabilization Program: A Firm-Level Simulation Analysis

Publisher: name: Unknown
Year: 1997
Subjects: Agricultural and Food Policy

description: This paper examines alternative risk management strategies in terms of their effectiveness for three representative Alberta farm operations. Stochastic dynamic simulation methods are used to model financial performance for these farms. The results suggest that government programs such as the Net Income Stabilization Account (NISA) program or the Farm Income Disaster Program (FIDP) in Alberta have some benefits in terms of supporting income levels and reducing the chances of farm failure. Neither program is very effective, however, in stabilizing year to year income or cash flow for the farm operations. The performance of NISA relative to alternative risk management programs and strategies such as FIDP, forward contracting or crop insurance, is mixed. In some cases, NISA does not seem to provide benefits beyond those available from other strategies.

Farm Management

description: Economic deregulation in New Zealand has forced farmers to adjust their management in order to survive without Government support in the globally competitive agrifood and fibre industry. In addition to managing a greater exposure to risk, farmers must now also obtain and interpret information about markets and new technology without the aid of a state-funded extension service, and be prepared to modify their production system and land-use according to international market signals. In this paper, aspects of the new economic environment for farming in New Zealand are described and some of the ways that farmers have adjusted their management to remain financially viable are presented. While the adjustment period has not been easy, farmers have benefited from increased efficiency in the finance, processing and transport sectors, and as a consequence, few wish to return to a highly regulated and subsidised economy.

Publisher: name: Unknown
Year: 1997
Subjects: Productivity Analysis

description: Production efficiency for five major crops (winter wheat, summer corn, spring cotton, and summer and spring soybean) grown in the north of China were estimated using a survey of249 households. The survey of rural households was conducted in Dengzhuang township, Hengshui Prefecture, Hebei Province, in 1993. Education and age of the major labourer had a positive effect on production efficiency. Efficiency was higher when females were the major labourer for all crops but spring cotton. Off-farm income had a positive effect, except for summer crops with high labour requirements. The presence of a tractor reduced efficiency, as did the area of fruit trees. Total household land area had a slightly positive effect on efficiency for all crops except soybean. Extension efforts to increase efficiency need to consider education and the gender of the major labourer. An understanding of the structure of the household and farm can assist preparation of appropriate extension programs.

Farm Management

description: Major changes in farm management practice are likely to occur in Australia over the next decade. These are likely to be paralleled by significant changes in land use. This will be a consequence of increased community awareness and global concern at the adverse environmental impacts of many agricultural practices. Major agricultural changes are likely to be;
• a reduction or cessation of burning of native vegetation to maintain biodiversity and conservation values and reduce greenhouse gas emissions
• reduced stocking rates on pastoral properties in the arid rangelands to limit land degradation affecting sustainability and to maintain biodiversity
9 retirement of significant areas of high conservation value and low profit lands from agriculture, and a shift to managing for biodiversity
• higher rates of stubble retention in cropping systems to improve sustainability and reduce greenhouse gas emissions
• reduced crop intensity and minimal cultivation to reduce soil loss in summer rainfall cropping systems to improve agricultural sustainability
9 increased prices and reduced availability of irrigation water, leading to a shift to higher value crops and much improved water use efficiencies 9 more complex property rights as indigenous peoples control more resources, resulting in a broader and richer range of environmental values to be considered.
These changes will require new attitudes and skills from farm managers.

Dispersive analysis of glueball masses

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We develop an inverse matrix method to solve for resonance masses from a dispersion relation obeyed by a correlation function. Given the operator product expansion (OPE) of a correlation function in the deep Euclidean region, we obtain the nonperturbative spectral density, which exhibits resonance structures naturally. The value of the gluon condensate in the OPE is fixed by producing the $ρ$ meson mass in the formalism, and then input into the dispersion relations for the scalar, pseudoscalar and tensor glueballs. It is shown that the low-energy limit of the correlation function for the scalar glueball, derived from the spectral density, discriminates the lattice estimate for the triple-gluon condensate from the single-instanton estimate. The spectral densities for the scalar and pseudoscalar glueballs reveal a double-peak structure: the peak located at lower mass implies that the $f_0(500)$ and $f_0(980)$ ($η$ ad $η'$) mesons contain small amount of gluonium components, and should be included into scalar (pseudoscalar) mixing frameworks. Another peak determines the scalar (pseudoscalar) glueball mass around 1.50 (1.75) GeV with a broad width about 200 MeV, suggesting that the $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$ ($η(1760)$) mesons are the glue-rich states. We also predict the topological susceptability $χ_t^{1/4}=75$-78 MeV, deduced from the correlation function for the pseudoscalar glueball at zero momentum. Our analysis gives no resonance solution for the tensor glueball, which may be attributed to the insufficient nonperturbative condensate information in the currently available OPE.

description: We exactly solve the ferromagnetic spin-1/2 Ising model on the Bethe lattice in the presence of an external magnetic field by means of the equations of motion method within the Green's function formalism. In particular, such an approach is applied to an isomorphic model of localized Fermi particles interacting via an intersite Coulomb interaction. A complete set of eigenoperators is found together with the corresponding eigenvalues. The Green's functions and the correlation functions are written in terms of a finite set of parameters to be self-consistently determined. A procedure is developed, that allows us to exactly fix the unknown parameters in the case of a Bethe lattice with any coordination number z. Non-local correlation functions up to four points are also provided together with a study of the relevant thermodynamic quantities.

Above the percolation threshold we present a polynomial-time algorithm that concentrates a universal cluster state, using resources that scale optimally in the size of the original lattice. On the other hand, below the percolation threshold, we show that single qubit measurements on the faulty lattice can be efficiently simulated classically. We observe a phase transition at the threshold when the amount of entanglement in the faulty lattice directly relevant to the computational power changes exponentially.

Sustainable Resource Management for the Millenium - The New Zealand Approach
Creators: name: Chaffey, John R.A.

Year: 1997
Subjects: Resource /Energy Economics and Policy

description: In 1991 New Zealand enacted a Resource Management Act (RMA) which radically altered the nation's approach to natural resource management and superseded fifty existing acts. The RMA defines sustainable management and requires that national, regional and local resource management fit that definition. Traditional planning criteria were replaced by an overarching criterion of impact on the environment; planning permission was replaced by resource consents; and the rural community has had to face significant changes in the legal requirements relating to land use.
This paper reviews the process of implementation of the RMA in one of the most rural districts in New Zealand; analyses the impact on rural land use and comments on its potential to achieve ongoing resource sustainability.

description: Ours could realistically be the generation to discover evidence of life beyond Earth. With this privileged potential comes responsibility. The magnitude of the question, "are we alone?", and the public interest therein, opens the possibility that results may be taken to imply more than the observations support, or than the observers intend. As life detection objectives become increasingly prominent in space sciences, it is essential to open a community dialog about how to convey information in a subject matter that is diverse, complicated, and has high potential to be sensationalized. Establishing best practices for communicating about life detection can serve to set reasonable expectations on the early stages of a hugely challenging endeavor, attach value to incremental steps along the path, and build public trust by making clear that "false starts" and "dead ends" are an expected and potentially productive part of the scientific process. Here, we endeavor to motivate and seed the discussion with basic considerations and offer an example of how such considerations might be incorporated and applied in a proof-of-concept-level framework. Everything mentioned herein, including the name of the confidence scale, is intended not as a prescription, but simply as the beginning of an important dialogue.

The strategy of production diversification, the vertical and horizontal integration, the process and product innovation seem to be a possible option for the vitality of agricultural enterprises. These activities insert a virtuous circle in these farms and in the areas where they are carried out. The authors present, through a theoretical analysis and real cases, the influence of this strategy on a farm in Umbria region of Italy with some final considerations regarding Italian and Japanese agritourism activity and perspective.

Subjects: Environmental Economics and Policy

description: A review of environmental consequences of the reform measures introduced in Hungarian agriculture is important when long-term policies on sustainable development are discussed The purposes of this paper are to learn lessons from the transformation of Hungarian agriculture and to derive policy implications on the environmental issues. Changes in market conditions have forced producers to lower the amounts of input use. This has positive and negative impacts on the environment and the sustainability of agricultural production. The transfer of agricultural land ownership to private hands through compensation laws has resulted in some adverse effects on the environment. A long-term strategy called the National Agricultural Policy (NAP) will bring in a more integrated approach to agricultural, rural development and the environmental issues. When the NAP is implemented, program area locations and coordination among different organizations should be reconsidered for the effective use of financial and human resources.

description: Recently, the Five-hundred-meter Aperture Spherical radio Telescope (FAST) measured the three-dimensional velocity of PSR J0538+2817 in its associated supernova remnant S147 and found a possible spin-velocity alignment in this pulsar. Here we show that the high velocity and the spin-velocity alignment in this pulsar can be explained by the so-called electromagnetic rocket mechanism. In this framework, the pulsar is kicked in the direction of the spin axis, which naturally explains the spin-velocity alignment. We scrutinize the evolution of this pulsar and show that the pulsar kick can create a highly relativistic jet at the opposite direction of the kick velocity. The lifetime and energetics of the jet is estimated. It is argued that the jet can generate a Gamma-ray Burst (GRB). The long term dynamical evolution of the jet is calculated. It is found that the shock radius of the jet should expand to about 32 pc at present, which is well consistent with the observed radius of the supernova remnant S147 ($32.1\pm4.8$ pc). Additionally, our calculations indicate that the current velocity of the GRB remnant should be about 440 km s$^{-1}$, which is also consistent with the observed blast wave velocity of the remnant of S147 (500 km s$^{-1}$).

Landcare in Australia - A success Story
Creators: name: Polkinghorne, Lachlan

Year: 1997
Subjects: Land Economics/Use

description: The emergence of the Landcare movement in Australia is relatively new.
“Landcare ” is the name given to a community based participatory program, initiated by the community and supported by governments of all persuasions. This paper provides a background to Landcare and why it has emerged as a significant force in encouraging environmental change. Australia is a large country with a diverse range of natural environments some of which are extremely fragile. Two hundred years of human occupation and agricultural activity has lead to significant degradation of natural resources. While some of this degradation will be very difficult to reverse, Landcare has provided a framework to address the problems, plan and implement solutions and most importantly to develop sustainable systems which are more empathetic with the environment on which they depend. Significant environmental problems include a continuing development of soil salinity in farming areas, the deterioration in waterway health and consequent water quality, erosion-and soil loss from farmed land, losses in biodiversity (vegetative and animal diversity) and thus an overall reduction in natural capital. Landcare, with its broad focus on the environment, has provided some solutions. There has been a substantial increase in awareness of the problems. There are many examples of success stories where environmental problems have been reduced or even eliminated Landcare has provided a catalyst for the development of new or modified farming systems which are more sustainable. Through Landcare, public funding providers have been provided with a focus which allows them to direct resources at a particular problem, such as water quality.
This paper also includes two case studies, providing examples of how Landcare can work for individuals and a community. It is impossible to represent the number and diversity of Landcare projects in operation, however the examples shown do help to build a picture of the operation of Landcare in Australia.

description: Using real-time charge sensing and gate pulsing techniques we measure the ratio of the rates for tunneling into the excited and ground spin states of a single-electron AlGaAs/GaAs quantum dot in a parallel magnetic field. We find that the ratio decreases with increasing magnetic field until tunneling into the excited spin state is completely suppressed. However, we find that by adjusting the voltages on the surface gates to change the orbital configuration of the dot we can restore tunneling into the excited spin state and that the ratio reaches a maximum when the dot is symmetric.

description: We investigate localization of entanglement of multipartite mixed Gaussian states into a pair of modes by local Gaussian measurements on the remaining modes and classical communication. We provide a detailed proof that for arbitrary symmetric Gaussian state maximum entanglement can be localized by homodyne detection of either amplitude or phase quadrature on each mode. We then consider arbitrary mixed three-mode Gaussian states and show that the optimal Gaussian measurement on one mode yielding maximum entanglement among the other two modes can be determined by calculating roots of a high-order polynomial. Finally, we discuss localization of entanglement with single-photon detection.

description: Unstable measures of governmental intervention in agriculture in Egypt have reflected on producers decision making in a manner distorting efficient prediction of major crops production levels. Liberalization and confinement of governmental intervention to price floor guarantee have permitted a stronger role for normal economic factors, proved by high estimated determination coefficients. Such change positively affects forcasting production sizes, imports needs and exports potentials in favor of efficient development planning.

description: In recent years physics-informed neural networks (PINNs) for approximating the solution to (initial-)boundary value problems gained a lot of interest. PINNs are trained to minimize several residuals of the problem in collocation points. In this work we tackle convection-dominated convection-diffusion problems, whose solutions usually possess layers, which are small regions where the solution has a steep gradient. Inspired by classical Shishkin meshes, we compare hard- constrained PINNs trained with layer-adapted collocation points with ones trained with equispaced and uniformly randomly chosen points. We observe that layer-adapted points work the best for a problem with an interior layer and the worst for a problem with boundary layers. For both problems at most acceptable solutions can be obtained with PINNs.
Farm Management in the Context of Deathly Embrace Between Agriculture and Industry: A Theoretical Model Analysis of a Two-Sector Developing Economy
Creators: name: Ayoola, G.B.

Year: 1997
Subjects: Farm Management

description: The case has been made for the need to develop a theory of policy intervention applicable to the peculiar circumstances of a developing economy. Towards this end a model has been developed that ascribes definite character to the agriculture-industry interrelationship in terms of the two sectors being engaged in theoretic ‘embrace’ that leads to the lack of economic progress. The Nigerian case provides the qualitative empirical base for substantiating the main proposition and postulating the several hypotheses. It is established that the critical elements of the farm enterprise are affected by the character of agriculture-industry interrelationship as it were, while the framework of analysis gives indications of new demand on the management capacity of farm-firms in particular. And, given the preponderance of small farms together with the strong family character and resource - poverty situation, the need for policy instruments at micro, meso and macro levels for upgrading farm management capabilities in developing economies becomes much clearer from the analysis. The role of farm management extension is most crucial among the possible modes of policy intervention for this purpose.

Aspects of structure in Gabriel Fauré’s Le jardin clos and related works
Creators: name: Skoumal, Zdenek Denny
Publisher: name: University of British Columbia
Year: 2010

description: Despite an ever-increasing number of specialized studies in music theory, only a limited number can be found which examine the music of Gabriel Faure. Most discussions of this music are in context of a historical overview, with emphasis on Faure's use of modality. This thesis presents detailed analyses of songs from the cycle Le Jardin Clos, Op. 106, and highlights several aspects of Faure's style. Various earlier songs are brought into the discussion in order to trace stylistic development and present evidence for views taken with regard to Le Jardin Clos. Although modality is periodically discussed (particularly in Chapters III and IV), the focus is not on this feature. Chapter I introduces the notion of ambiguity, a problem encountered commonly in the analysis of Faure's music. It then proceeds to point out one source of ambiguity--harmonic progressions derived from the implications inherent in the motions of outer voices. Particular attention is given to instances where the outer voices move "in contrary motion to create wedge-shaped structures. In this chapter, linear motion is emphasized. Chapter II turns to various structures of third-relation. The most extended portion of the chapter is devoted to a discussion of the "superchord", a tertian structure which, although heard in segments only, appears as a controlling element in larger areas of music. Distinction is made between this phenomenon and a normal progression in thirds (i-VI-iv). Other structures related to the superchord are also considered. The last example of Chapter II shows a structure based on a combination of a tertian design and a wedge shape. In Chapter III, various non-traditional ways of treating the leading tone are examined. In addition to leading tones which are lowered (in modal and tonal contexts) or avoided, the discussion concentrates on melodic lines which rise to the leading tone and retreat downward. Chapter IV reviews melodic characteristics encountered up to that point, and, with the addition of further features, presents a melody typical of Faure's later style. The major issue in this chapter concerns melodies that center around the fifth degree of the scale. The final chapter returns to the topic of ambiguity by discussing instances where two tonal centers are juxtaposed. This feature of Faure's music is distinguished from bitonality, as the latter is generally understood.

description: In this work, we study the statistical behavior of entanglement in quantum bipartite systems under the Hilbert-Schmidt ensemble as assessed by the standard measure - the von Neumann entropy. Expressions of the first three exact cumulants of von Neumann entropy are known in the literature. The main contribution of the present work is the exact formula of the corresponding fourth cumulant that controls the tail behavior of the distribution. As a key ingredient in deriving the result, we make use of newly observed unsimplifiable summation bases that lead to a complete cancellation. In addition to providing further evidence of the conjectured Gaussian limit of the von Neumann entropy, the obtained formula also provides an improved finite-size approximation to the distribution.
