description: Faussurier et al. [Phys. Rev. E 65, 016403 (2001)] proposed to use a variational principle relying on Jensen-Feynman (or Gibbs-Bogoliubov) inequality in order to optimize the accounting for two-particle interactions in the calculation of canonical partition functions. It consists in a decomposition into a reference electron system and a first-order correction. The procedure appears to be very efficient in order to evaluate the free energy and the orbital populations. In this work, we present numerical applications of the method and propose to extend it using a reference energy which includes the interaction between two electrons inside a given orbital. This is possible thanks to our efficient recursion relation for the calculation of partition functions. We also show that a linear reference energy, however, is usually sufficient to achieve a good precision and that the most promising way to improve the approach of Faussurier et al. is to apply Jensen's inequality to a more convenient convex function.

The role of DNP in antigen activation of cellular immune responses
Creators: name: Waterfield, John Douglas
Publisher: name: University of British Columbia
Year: 2011

description: In animals immunized with 2,4 dinitrophenyl (DNP) hapten-carrier protein conjugates, no in vitro cellular response is elicited by DNP, either alone, or when coupled to a heterologous carrier. In contrast, animals immunized with haptenic peptide-carrier conjugates do mount an in vitro cellular response towards the haptenic peptide. This apparent inconsistency led us to compare the in vivo and in vitro cellular immune responses to a synthetic peptide antigen and its DNP derivative to determine the activation specificity of the cells evoking this response. Guinea pigs were immunized with either the DNP substituted immunogen (DNP-N-10-C) or its unsubstituted form (N-10-C) and subsequent in vivo or in vitro cellular activation was evaluated for DNP alone, DNP coupled to the homologous determinant, and DNP coupled to heterologous carriers. The data suggests that in DNP-N-10-C immune guinea pigs, DNP substitution opens a new determinant exhibiting, in antigen reactive cells, a unique specificity towards the DNP moiety as well as a portion of the peptide to which it is conjugated. However the DNP group by itself does not have the configurational requirement to evoke cellular activation. It therefore plays a minor role in activation of the cellular immune response; the major contribution being supplied by the peptide portion of the 'shared' determinant.

description: In this work, we review the results of Refs [1]-[5] dedicated to the description of the early Universe cosmology induced by quantum and thermal effects in superstring theories. The present evolution of the Universe is described very accurately by the standard Lambda-CDM scenario, while very little is known about the early cosmological eras. String theory provides a consistent microscopic theory to account for such missing epochs. In our framework, the Universe is a torus filled with a gas of superstrings. We first show how to describe the thermodynamical properties of this system, namely energy density and pressure, by introducing temperature and supersymmetry breaking effects at a fundamental level by appropriate boundary conditions. We focus on the intermediate period of the history: After the very early "Hagedorn era" and before the late electroweak phase transition. We determine the back-reaction of the gas of strings on the initially static space-time, which then yields the induced cosmology. The consistency of our approach is guaranteed by checking the quasi-staticness of the evolution. It turns out that for arbitrary initial boundary conditions at the exit of the Hagedorn era, the quasi-static evolutions are universally attracted to radiation-dominated solutions. It is shown that at these attractor points, the temperature, the inverse scale factor of the Universe and the supersymmetry breaking scale evolve proportionally. There are two important effects which result from the underlying string description. First, initially small internal dimensions can be spontaneously decompactified during the attraction to a radiation dominated Universe. Second, the radii of internal dimensions can be stabilized.

description: Climate change, and its associated climate variability, has significant impacts on the wine industry and these changes will increasingly be felt along the whole chain of companies that produce, handle, process and market wine. There has been very little work in understanding how wine consumers perceive both the climate change mitigation and adaptation efforts of these companies. This study was conducted to explore Australian wine consumer perceptions towards climate change adaptation and the impacts of climate change on the growing, making and marketing of wine. Data were collected through four focus groups discussions, with a total of of 30 Australian wine consumers. This paper reports the preliminary results of data analysis. Findings revealed that participants are concerned for the production and quality of Australian wines, but their purchase decisions and drinking habits are still guided predominantly by non- environmental factors. They would, however, like to make informed decisions on wine purchase and consumption considering climate, which suggests wine businesses could benefit from educating consumers, and communicating specific climate adaptation information to consumers in a timely manner.

description: Excerpts from the Preface: Many publications have been written throughout the world on drainage research and its applications. Since 1955, materials such as plastics have opened up new fields of drainage and seepage control; machinery has been developed for all types of drainage materials; new methods have been used to speed up drainage; improved practices have been developed for irrigation and salinity control; and better maintenance has helped solve some of the problems of drainage in the field. Moreover, research in related areas such as soil physics, hydrology, and hydraulics has created new Instruments and techniques which have improved drainage procedures. To keep up with the demand for Information on both surface and subsurface drainage, this annotated bibliography has been compiled. Hopefully, it will prove useful as a ready reference to all those interested in drainage and its many aspects such as history, economics, needs, designs, applications, use, and problems.

description: The fractional AC Josephson effect is a discerning property of topological superconductivity in hybrid Josephson junctions. Recent experimental observations of missing odd Shapiro steps and half Josephson frequency emission in various materials have sparked significant debate regarding their potential origin in the effect. In this study, we present microwave emission measurements on a resistively shunted Josephson junction based on a HgTe quantum well. We demonstrate that, with significant spurious inductance in the shunt wiring, the experiment operates in a nonlinear dynamic regime characterized by period-doubling. This leads to additional microwave emission peaks at half of the Josephson frequency, $f_J/2$, which can mimic the $4π$-periodicity of topological Andreev states. The observed current-voltage characteristics and emission spectra are well-described by a simple RCLSJ model. Furthermore, we show that the nonlinear dynamics of the junction can be controlled using gate voltage, magnetic field, and temperature, with our model accurately reproducing these effects without incorporating any topological attributes. Our observations urge caution in interpreting emission at $f_J/2$ as evidence for gapless Andreev bound states in topological junctions and suggest the appropriate parameter range for future experiments.

description: Centrality measures derived from character networks can be used to detect the main characters in a play. For example, previous research has shown that characters with high network centrality typically perform the majority of speech acts and appear in most of the scenes. However, one can extract character networks from plays in various ways. Close reading may omit minor characters like attendants or servants, while distant reading (e.g., parsing an XML file) may include aggregate characters like "All", "Both Lords", or similar. Furthermore, the networks may display either implicit or explicit connections, depending on whether we connect characters because they appear in the same scene or because they are directly addressing each other, respectively. Thus, as adding more characters or connections to the network affects centralities and other network measures, the interpretation of both qualitative and quantitative aspects of character networks depends on the extraction method. In this work we are concerned with the specific question whether details of the textual source and the extraction method, such as adding minor or aggregate characters, make main characters less "central". Answering this question will allow us to better assess the validity of automated literary network analysis.

description: Agriculture is an industry riddled with risk and uncertainty. In fact, agriculture rates amongst the highest risk industries in the world1. Climate change, pests and disease, demand for growth, global markets and trade, regulations and consumer preferences are all contributing to the increasing level of risk faced by farmers. And yet, agriculture is the least prepared industry for managing risk2. For farm managers, risk and uncertainty can lead to poor decision-making, to the detriment of the farm and agricultural sector. Risk management involves applying a process by which farmers are equipped to reduce uncertainty and take calculated risks that support effective decision-making. The Organisation for Economic Co-operation and Development published two studies3 recommending a holistic approach to risk management. This type of approach has not been applied in Canada. This paper explores the development of AgriShieldÂ®, an online risk management platform that gives farmers a 360ï‚° view of the risks they face to improve the adoption of a comprehensive approach to managing risk by Canadaâ€™s farmers.

description: During a period when agricultural management signals and imperatives are being reviewed internationally, this paper explores the balance between production-linked and environmental care aspects. It reviews the case of the UK, especially England with particular reference to Exmoor in the south-west. However, it seeks to elicit some principles that may seem to apply internationally. After a review of policy signals and reactions over the past half-century or so in the UK, it outlines the September 2018 Agriculture Bill, discusses the changes it may herald, and the issues that need to be incorporated in the final Environmental Land Management System (ELMS) being debated in the UK Parliament at the time of writing. These include a global perspective on farming policies, agricultural innovations, energy security and care of the farmed landscape. It is argued that an overarching vision of Ecosystem Security includes people and it is proposed that food production and productivity (measured in terms of the rate of output per unit of input) must be included within the â€˜envelopeâ€™ of ecosystem services and in the valuation of natural capital. Both necessary agricultural productivity and responsible environmental management are mutually inclusive and require policies that integrate them as simply as is possible.

description: We consider nonanticommutative SYM theories with chiral matter in the adjoint representation of the SU(N) x U(1) gauge group. In a superspace setup and manifest background covariant approach we investigate the one-loop renormalization of the theory when a cubic superpotential is present. The structure of the divergent terms reveals that the theory simply obtained from the ordinary one by trading products for star products is not renormalizable. Moreover, because of the different renormalization undergone by the abelian field compared to the non-abelian ones, the superpotential seems to be incompatible with the requests of renormalizability, gauge and N=1/2 invariance. However, by a suitable modification of the quadratic action for the U(1) (anti)chiral superfields and the addition of extra couplings, we find an action which is one-loop renormalizable and manifestly N=1/2 supersymmetric and supergauge invariant. We conclude that interacting matter can be safely introduced in NAC gauge theories, in contrast with previous results.

Thus, entropy grows in the Universe, contrary to Standard Cosmology prediction.

description: We report on the discovery of a high velocity B star, HD 69686. We estimate its space velocity, distance, surface temperature, gravity, and age. With these data, we are able to reconstruct the trajectory of the star and to trace it back to its birthplace. We use evolutionary tracks for single stars to estimate that HD 69686 was born 73 Myr ago in the outer part of our Galaxy ($r \sim 12$ kpc) at a position well below the Galactic plane ($z \sim -1.8$ kpc), a very unusual birthplace for a B star. Along the star's projected path in the sky, we also find about 12 other stars having similar proper motions, and their photometry data suggest that they are located at the same distance as HD 69686 and probably have the same age. We speculate on the origin of this group by star formation in a high velocity cloud or as a Galactic merger fragment.

La pretesa a un’amministrazione imparziale. Note sul conflitto d’interessi nel diritto amministrativo
Creators: name: Piazza, Ippolito
Publisher: name: P.A. Persona e Amministrazione
Year: 2020

description: Il principio di imparzialità dell’amministrazione è stato tradizionalmente guardato dal punto di vista dell’amministrazione, mentre più rari sono stati i tentativi di studiare l’imparzialità dalla prospettiva del cittadino, facendone cioè l’oggetto di una pretesa individuale. Muovendo da questa constatazione, il lavoro tenta di ricostruire il contenuto di una pretesa all’amministrazione imparziale, con particolare riferimento alla neutralità del funzionario. Il tentativo rivela la sua utilità nel superamento di numerosi problemi applicativi che derivano proprio dalla difficile emersione di un interesse individuale all’imparzialità e dalla sua commistione con l’interesse pubblico. Nell’applicazione della disciplina delle incompatibilità e del conflitto d’interessi nel diritto amministrativo, la sovrapposizione tra l’interesse del privato a un trattamento imparziale e quello pubblico all’immagine di un’amministrazione super partes ha, infatti, spesso condotto a conseguenze radicali in termini di tutela, cioè all’annullamento di provvedimenti sostanzialmente corretti adottati da organi non-imparziali, o viceversa, sulla base di insoddisfacenti temperamenti, alla loro conservazione in nome del buon andamento. L’individuazione di una pretesa individuale alla neutralità del decisore, fondata sulla base dell’art. 6-bis della legge sul procedimento, sembra invece consentire al privato la garanza di una tutela piena nei limiti della legge e conforme a una giurisdizione amministrativa caratterizzata in senso soggettivo. The principle of impartiality has traditionally been studied from the point of view of the public administration, while attempts to look at impartiality from a citizen’s perspective have been rarer in academic literature. The paper aims to identify the content of an individual right to impartial administration, with particular reference to the neutrality of the civil servant. The lack of such an individual right creates various problems in practice, which arise from the overlap between private and public interest. The rules on the conflict of interest in administrative law often lead to the annulment of substantially correct measures adopted by non-partisan bodies, or vice versa, to their preservation in the name of the efficiency of administration. The definition of an individual right to the neutrality of the decision-maker, based on Art. 6-bis of the Administrative Procedure Act (Law n. 241/90), seems instead to allow the citizen the guarantee of full protection within the limits of the law and in accordance with the nature of administrative jurisdiction.

description: There are considerable challenges to be faced to earn a livelihood from the semi-arid land of Laikipia, Kenya. These include periodic droughts, lack of water resources, poor infrastructure, lack of political support and the need for cooperation with neighbours. Since Kenya became independent in 1963, there have been big changes in the management of these properties, the most notable being the introduction of tourism in the 1980s which has prospered owing to the large reservoir of wildlife which exists in the area and the formation of Conservancies to protect the latter. Much of the income of the ranches is now derived from upmarket tourist lodges and safaris. However, they are still major food producers especially of quality livestock and some crops. Particular reference is made to the combined Lewa/Borana Conservancy which consists of two privately owned conservancies which have removed the fences between them to establish the largest Conservancy in the Country with a rich population of wildlife. A large area of land within Lewa was owned by one of the authorâ€™s relatives until the 1980s and his personal experience of its development over the past half century is detailed in this presentation. Conclusions for a better future are drawn.

description: HD179821 is an enigmatic evolved star that possesses characteristics of both a post-asymptotic giant branch star and a yellow hyper-giant, and there has been no evidence that unambiguously defines its nature. These two hypotheses are products of an indeterminate distance, presumed to be 1 kpc or 6 kpc. We have obtained the two-epoch Hubble Space Telescope WFPC2 data of its circumstellar shell, which shows multiple concentric arcs extending out to about 8 arcsec. We have performed differential proper-motion measurements on distinct structures within the circumstellar shell of this mysterious star in hopes of determining the distance to the object, and thereby distinguishing the nature of this enigmatic stellar source. Upon investigation, rather than azimuthal radially symmetric expansion, we discovered a bulk motion of the circumstellar shell of (2.41+-0.43, 2.97+-0.32) mas/yr. This corresponded to a translational ISM flow of (1.28+-0.95, 7.27+-0.75) mas/yr local to the star. This finding implies that the distance to HD 179821 should be rather small in order for its circumstellar shell to preserve its highly intact spherical structure in the presence of the distorting ISM flow, therefore favoring the proposition that HD 179821 is a post-AGB object.

description: One of the fundamental tenets of quantum mechanics is that non-orthogonal states cannot be distinguished perfectly. When distinguishing multiple copies of a mixed quantum state, a collective measurement, which generates entanglement between the different copies of the unknown state, can achieve a lower error probability than non-entangling measurements. The error probability that can be attained using a collective measurement on a finite number of copies of the unknown state is given by the Helstrom bound. In the limit where we can perform a collective measurement on asymptotically many copies of the quantum state, the quantum Chernoff bound gives the attainable error probability. It is natural to ask at what rate does the error tend to this asymptotic limit, and whether the asymptotic limit can be attained for any finite number of copies. In this paper we address these questions. We find analytic expressions for the Helstrom bound for arbitrarily many copies of the unknown state in several simple qubit examples. Using these analytic expressions, we investigate how the attainable error rate changes as we allow collective measurements on finite numbers of copies of the quantum state. We also investigate the necessary conditions to saturate the M-copy Helstrom bound. It is known that a collective measurement on all M-copies of the unknown state is always sufficient to saturate the M-copy Helstrom bound. However, general conditions for when such a measurement is necessary to saturate the Helstrom bound remain unknown. We investigate specific measurement strategies which involve entangling operations on fewer than all M-copies of the unknown state. For many regimes we find that a collective measurement on all M-copies of the unknown state is necessary to saturate the M-copy Helstrom bound.

description: The purpose of the paper is to identify trends in the profitability and the impact of subsidies upon a group of large farms. The paper analyses the main financial results of 32 big farms covering 83,300 ha located on the most fertile farmland in southern Romania. Each indicator is tracked from 2010 till 2017 and then summed up to the level of the 32 farms; the analysis is made on the aggregated level. Thus, we analyze assets, capital, debts, income, turnover, expenses, net profit, subsidies, number of employees and we computed profitability and productivity. During the eight years under review, farms are capitalizing, investing in assets, they are growing and diversifying, reducing their need for loans and their indebtedness ratio. The need for capital increases, while the assignability and attractiveness fall. The number of employees increases and their productivity drops. Subsidies go up and even profit margins are small, profitability and productivity rise and thus, farms efficiency are growing.

description: The European Dairy Farmers (EDF) Snapshot 2018 focused on â€œAnimal Welfareâ€ as animal welfare is a daily concern of dairy farmers and is increasingly important to those outside farming. 201 farmers from 16 countries participated in the survey. First descriptive results are presented in this paper. Even though the results are not representative, they offer interesting insights into the farmersâ€™ perception of animal welfare: According to the participating EDF farmers, animal welfare is of high importance throughout the supply chain, but they also see different priorities for animal welfare aspects. Where EDF farmers consider animal health as the most important aspect, society seems to attach great importance to grazing. In addition to legal and dairy processorsâ€™ requirements concerning all farmers in the respective countries, half of the EDF farmers join voluntarily at least one additional programme concerning animal welfare. EDF farmers are mainly motivated to implement animal welfare criteria to improve the cowsâ€™ welfare and to increase profitability. The EDF Snapshot data provides interesting insights into the status quo of animal welfare in European dairy farms and forms the basis for further research. EDF members use the results to discuss the current situation and to optimise their own farm strategies.

Blockchain provides a decentralized, immutable, and secure verification system for food and agricultural products, from local farms to the global table. The objective of this work is to trace the potential role of blockchain in Wyoming agricultural products and marketing options. While the applications are in the early stages of development, we find that farms or ranches may benefit from a thorough understanding of this technology. Recent changes in Wyoming state law facilitate the development of blockchain. This paper describes the technology, reviews applications within the food system, describes state law changes, and identifies considerations associated with the technology for advisors.

description: Benchmarking is the practice of establishing the relative performance of a business against an appropriate standard, which can be self-set targets or peer performance. It identifies the excessive costs and inefficiencies of a business, increasing its competitiveness and ability to outperform others. Dairy System Monitoring (DSM) has been operating for twenty years as a consultancy service that benchmarks over 150 New Zealand and Tasmanian dairy farmers. Its aim is to work alongside farmers, collecting and sharing interpretation of their farm data in a manner that motivates and more actively engages them with their business. DSM participants perform ahead of the New Zealand national average for operating profit as the DSM service enables individuals to verify current performance and make good decisions. It is also a useful analysis tool for consultants. It is used to develop guidelines for managing home-grown forage; continuously update and respond to farm performance information; and critically examine expenditure in-line with physical performance. In conclusion, the DSM service can confirm mainstream science, but it also progresses to the next stage with analysis on profit drivers that create clarity around the strengths and weaknesses of individual businesses, directing performance beyond industry averages.

description: We report the discovery of an eclipsing polar, 2XMMi J225036.9+573154, using XMM-Newton. It was discovered by searching the light curves in the 2XMMi catalogue for objects showing X-ray variability. Its X-ray light curve shows a total eclipse of the white dwarf by the secondary star every 174 mins. An extended pre-eclipse absorption dip is observed in soft X-rays at phi=0.8-0.9, with evidence for a further dip in the soft X-ray light curve at phi~0.4. Further, X-rays are seen from all orbital phases (apart from the eclipse) which makes it unusual amongst eclipsing polars. We have identified the optical counterpart, which is faint (r=21), and shows a deep eclipse (>3.5 mag in white light). Its X-ray spectrum does not show a distinct soft X-ray component which is seen in many, but not all, polars. Its optical spectrum shows Halpha in emission for a fraction of the orbital period.

description: The stellar metallicity and its gradient pose constraints to the formation and evolution of galaxies. This is a study of the metallicity gradient of the LMC, SMC and M33 galaxies derived from their asymptotic giant branch (AGB) stars. The [Fe/H] abundance was derived from the ratio between C- and M-type AGB stars and its variation analysed as a function of galactocentric distance. Galaxy structure parameters were adopted from the literature. The metallicity of the LMC decreases linearly as -0.047+/-0.003 dex/kpc out to ~8 kpc from the centre. In the SMC, [Fe/H] has a constant value of ~ -1.25+/-0.01 dex up to ~ 12 kpc. The gradient of the M33 disc, until ~ 9 kpc, is -0.078+/-0.003 dex/kpc while an outer disc/halo, out to ~ 25 kpc, has [Fe/H] ~ -1.7 dex. The metallicity of the LMC, as traced by different populations, bears the signature of two major star forming episodes: the first one constituting a thick disc/halo population and the second one a thin disc and bar due to a close encounter with the MW and SMC. The [Fe/H] of the recent episode supports an LMC origin for the Stream. The metallicity of the SMC supports star formation, ~ 3 Gyr ago, as triggered by LMC interaction and sustained by the bar in the outer region of the galaxy. The SMC [Fe/H] agrees with the present-day abundance in the Bridge and shows no significant gradient. The metallicity of M33 supports an ``inside-out'' disc formation via accretion of metal poor gas from the interstellar medium.

NPR - TOWARD A BETTER NATURAL RESOURCE MANAGEMENT DELIVERY MODEL WITH A GREATER EMPHASIS ON THE FARMING SECTOR â€“ THE TAMAR VALLEY EXPERIENCE

description: A belief that the current natural resource management (NRM) delivery model in Australia is failing to provide tangible on ground outcomes within the farming sector is proving to be a catalyst for the examination of alternative delivery models. However, there exist workable examples contributing to on-farm NRM and production outcomes that provide value for money investment, with the flexibility to cater to local needs at a sub- regional level. These community-based models owe their success by being truly community driven and more closely linked to producers and local government than the regional NRMs are. The Tamar Valley has such a community driven model, which demonstrates another way for NRM program and project delivery into the farming sector.

Perspective acceleration and gravitational redshift. Measuring masses of individual white dwarfs using Gaia + SIM astrometry

description: According to current plans, the SIM/NASA mission will be launched just after the end of operations for the Gaia/ESA mission. This is a new situation which enables long term astrometric projects that could not be achieved by either mission alone. Using the well-known perspective acceleration effect on astrometric measurements, the true heliocentric radial velocity of a nearby star can be measured with great precision if the time baseline of the astrometric measurements is long enough. Since white dwarfs are compact objects, the gravitational redshift can be quite large (40-80 km/s), and is the predominant source of any shift in wavelength. The mismatch of the true radial velocity with the spectroscopic shift thus leads to a direct measure of the Mass--Radius relation for such objects. Using available catalog information about the known nearby white dwarfs, we estimate how many masses/gravitational redshift measurements can be obtained with an accuracy better than 2%. Nearby white dwarfs are relatively faint objects (10 < V < 15), which can be easily observed by both missions. We also briefly discuss how the presence of a long period planet can mask the astrometric signal of perspective acceleration.

description: Spin susceptibility of superfluid 3He-B film with specular surfaces is calculated. It is shown that, when the magnetic field is applied in a direction perpendiculr to the film, the suseptibility is significantly enhanced by the contribution from the surface bound states. No such enhancement is found for the magnetic field parallel to the film. A simplified model with spatially constant order parameter is used to elucidate the magnetic properties of the surface bound states. The Majorana nature of the zero energy bound state is also mentioned.

description: Prenylated flavonoids show antibacterial activity towards Staphylococcus aureus (S. aureus). Previous studies have suggested that the prenyl side-chain is an important active group for antimicrobial activity. However, prenylated flavonoids also often contain a pyran ring isopentene group. Few studies have explored the contribution of the pyran ring isopentene group to antibacterial activity. In this study, the antibacterial activities of structurally related flavonoid compounds from mulberry root bark were studied by detecting the minimum inhibitory concentration (MIC) and colony counting. These flavonoid compounds all exhibited antibacterial activities against S. aureus ATCC6538, S. aureus ATCC25923 and methicillin-resistant S. aureus (MRSA) ATCC43300 with MIC values of 7.3–248.2 μmol/L, 7.3–330.9 μmol/L, and 7.3–330.9 μmol/L, respectively. Structure-activity relationship analyses demonstrated that the pyran ring isopentene group plays an important role in antibacterial activity. Thus, the pyran ring isopentene group is an overlooked antimicrobial active group in prenylated flavonoids.

description: By analyzing the dynamical properties of particle production in relativistic heavy ion collisions, it is possible to characterize the final stage of the equilibration process occurring in the collision fireball. In this work, we use the Hagedorn model coupled with non-extensive statistics to evaluate the transverse momentum spectra of positive pions for various event centrality classes in Au+Au collisions at RHIC with center-of-mass energies of 62.4GeV/A and 200GeV/A. We find that, by assuming an energy distribution that incorporates particle correlations, it is possible to explain the entire $π^{+}$ $p_{T}$ spectrum as measured by RHIC. We find that spectra from central collisions, when compared to peripheral collisions, are consistent with a system that has smaller values of the non-extensivity parameter "q" and higher values of temperature. Comparison between different beam energies also shows a variation of the "q" parameter. The result is discussed using the interpretation that the "q" parameter is a measure of particle correlations within the system. Under this assumption, our results show that more central collisions are consistent with a system with less particle correlations.
