description: In central collisions at RHIC, the initial production of heavy quarks will for the first time yield multiple pairs of c-cbar in each central event. If a region of deconfined quarks and gluons is subsequently formed, a new mechanism for the formation of heavy quarkonium bound states will be activated. This will result from the mobility of heavy quarks in the deconfined region, such that bound states can be formed from a quark and an antiquark which were originally produced in separate incoherent interactions. Our model estimates of this effect predict a dramatic increase in the number of observed J/Psi at RHIC, over that predicted from extrapolation of color-screening or gluon dissociation mechanisms from the lower CERN-SPS energies. The centrality and energy dependence of this effect should be readily observable by the Star and Phenix detectors. Thus the J/Psi abundance at RHIC will continue to provide a signature of QGP formation. However, it is in this environment a more useful probe, since contrary to prior expectations this large predicted J/Psi abundance should be relatively easy to measure.

description: Open quantum many-body systems are of both fundamental and applicational interest. However, it remains an open challenge to simulate and solve such systems, both with state-of-the-art classical methods and with quantum-simulation protocols. To overcome this challenge, we introduce a simulator for open quantum many-body systems based on giant atoms, i.e., atoms (possibly artificial), that couple to a waveguide at multiple points, which can be wavelengths apart. We first show that a simulator consisting of two giant atoms can simulate the dynamics of two coupled qubits, where one qubit is subject to different drive amplitudes and dissipation rates. This simulation enables characterizing the quantum Zeno crossover in this model. We further show that by equipping the simulator with post-selection, it becomes possible to simulate the effective non-Hermitian Hamiltonian dynamics of the system and thereby characterize the transition from oscillatory to non-oscillatory dynamics due to varying dissipation rates. We demonstrate and analyze the robustness of these simulation results against noise affecting the giant atoms. Finally, we discuss and show how giant-atom-based simulators can be scaled up for digital-analog simulation of large open quantum many-body systems, e.g., generic dissipative spin models.

description: We completely characterize the weighted Lebesgue spaces on the torus $\mathbb T^n$ and waveguide manifold $\mathbb T^n \times \mathbb R^m$ for which the solutions of the heat equation converge pointwise (as time tends to zero) to the initial data. In the process, we also characterize the weighted Lebesgue spaces for the boundedness of maximal operators on the torus and waveguide manifold, which may be of independent interest.

This is a lyric novel exploring the role of womanhood and family in the age of plastic. It draws from relevant works of critical theory and poetry in order to propose a codification of disposability, what can and cannot be replaced in the anthropocene age. These explorations and propositions are filtered through the novel’s protagonist, Clarice, who endures a maximalist odyssey, through cityscape and landfill alike.

description: The potential for soil carbon sequestration to play a significant role in meeting Australia’s greenhouse reduction targets has attracted widespread interest. Despite this interest, the economic scope for soil carbon sequestration remains poorly understood and the practical approaches that could be used to capture any opportunities have not been explored. In this paper we present preliminary results on a pilot soil carbon sequestration variable price, reverse tender auction in the mixed (wheat-sheep) farming system of the Lachlan Catchment, NSW. We draw on the results of the pilot to reveal; contract choice, landholders costs of soil carbon sequestration and the extent and impact of transaction costs associated with basic cost-effectiveness of the market mechanism.
Matter-wave interferometry with atoms in high Rydberg states

description: Matter-wave interferometry has been performed with helium atoms in high Rydberg states. In the experiments the atoms were prepared in coherent superpositions of Rydberg states with different electric dipole moments. Upon the application of an inhomogeneous electric field, the different forces on these internal state components resulted in the generation of coherent superpositions of momentum states. Using a sequence of microwave and electric field gradient pulses the internal Rydberg states were entangled with the momentum states associated with the external motion of these matter waves. Under these conditions matter-wave interference was observed by monitoring the populations of the Rydberg states as the magnitudes and durations of the pulsed electric field gradients were adjusted. The results of the experiments have been compared to, and are in excellent quantitative agreement with, matter-wave interference patterns calculated for the corresponding pulse sequences. For the Rydberg states used, the spatial extent of the Rydberg electron wavefunction was ~320 nm. Matter-wave interferometry with such giant atoms is of interest in the exploration of the boundary between quantum and classical mechanics. The results presented also open new possibilities for measurements of the acceleration of Rydberg positronium or antihydrogen atoms in the Earth's gravitational field.

description: At its Sixth National Party Congress in December 1986, a drastic leadership change occurred in the Communist Party of Vietnam (CPV). Truong Chinh, Pham Van Dong and Le Due Tho all stepped down from top Party positions, accepting most of the blame for the country's appalling socio-economic condition. The new leadership that replaced them, led by Nguyen Van Linh, is now faced with the task of reforming the country's ailing economy. To do this, it has embarked on a wide-ranging series of economic reforms. As these reforms gain momentum in the second half of the 1980s, it has seen the concomitant rise of a new class of leaders in the Politburo labelled as "reformers", the most prominent of whom are the country's new leader, Nguyen Van Linh, and the State Planning Commission Chairman.

description: This paper assesses the impact of chicken vaccination on farmers’ income. A dynamic simulation model, VIPOSIM, combined with benefit-cost techniques, was used ensuring that both, the dynamic aspects of village poultry production system and selection bias are addressed. The findings of this study reveal that, in general, Newcastle Disease (ND) control results in a considerable increase in farmers’ income. Economic profitability is not the underlying factor for low rates of chicken vaccination. To address adequately the adoption of ND control technology, the government should concentrate efforts on the strategies of extension and distribution of the vaccine.

description: We study the finite temperature Fermi-liquid to non-Fermi-liquid crossover in the 2D Hubbard model for a range of dopings using the self-consistent ladder dual fermion method. We consider relatively high temperatures where we identify a suppression of the density of states near the Fermi level caused by a quasi-antiferromagnetic behaviour that is itself characterized by a long, but finite, correlation length scale. We perform fluctuation diagnostics to decompose the single-particle self energy into scattering $q$-vector and bosonic frequency contributions. Within this framework we find that the key contributions to the single-particle self energy that give non-Fermi-liquid character, even at weak coupling, are caused by relatively sharp $q=(π,π)$ spin fluctuations, while the decomposition in the bosonic frequency channel shows a complicated dependence on the relative strengths of zero, positive and negative frequency contributions. Finally, variation in density suggests that the tendency towards non-Fermi-liquid behavior is not substantially different for electron or hole doped systems.

description: Trust plays a pivotal role in Lecturer-Student-Collaboration, encompassing teaching and research aspects. The advent of Large Language Models (LLMs) in platforms like Open AI's ChatGPT, coupled with their cost-effectiveness and high-quality results, has led to their rapid adoption among university students. However, discerning genuine student input from LLM-generated output poses a challenge for lecturers. This dilemma jeopardizes the trust relationship between lecturers and students, potentially impacting university downstream activities, particularly collaborative research initiatives. Despite attempts to establish guidelines for student LLM use, a clear framework mutually beneficial for lecturers and students in higher education remains elusive. This study addresses the research question: How does the use of LLMs by students impact Informational and Procedural Justice, influencing Team Trust and Expected Team Performance? Methodically, we applied a quantitative construct-based survey, evaluated using techniques of Structural Equation Modelling (PLS- SEM) to examine potential relationships among these constructs. Our findings based on 23 valid respondents from Ndejje University indicate that lecturers are less concerned about the fairness of LLM use per se but are more focused on the transparency of student utilization, which significantly influences Team Trust positively. This research contributes to the global discourse on integrating and regulating LLMs and subsequent models in education. We propose that guidelines should support LLM use while enforcing transparency in Lecturer-Student- Collaboration to foster Team Trust and Performance. The study contributes valuable insights for shaping policies enabling ethical and transparent LLMs usage in education to ensure effectiveness of collaborative learning environments.

Estimation of demand for tea and coffee in Australia

description: This study attempts to review the basic principles of the consumer demand theory in order to estimate the demand for tea and coffee in Australia. Generally the study of consumer demand theory is important because it can be used in development and production planning. Some of the commonly used systems of demand equations for empirical studies are explained. The study also attempts to explain a habit formation hypothesis and incorporate the hypothesis in the systems of demand equations. On this basis, three models of demand equations with and without habit formation are used to estimate the demand for tea and coffee in Australia. It is shown that none of the models satisfy all the general restrictions imposed on demand equations, since each one has some advantages and some disadvantages. However, through the comparison of these models it is shown that a habit formation model is justified. Tea in the Australian consumption pattern is an inferior good while coffee is a normal commodity. On the basis of the alternative functional forms, it seems that the double logarithmic system is a better model for estimating the demand for a single commodity such as tea or coffee.

description: Chauliodoniscus Lincoln, 1985
 Type species: Chauliodoniscus tasmanaeus Lincoln, 1985.
 Diagnosis. Haloniscidae with pereonites 5–7 free (pleotelson may be fused mid-dorsally with one or two pereonites but lateral margins are separated), one or more of pereonites 2–4 with prolonged anterolateral angles. Cephalon without rostrum. Body subcylindrical and capable of rolling like a ball. Article 3 of antenna 2 with or without long spinous process. Pleotelson with posterior margin truncated or broadly rounded.
 Remarks. The definition of Chauliodoniscus is modified to accommodate C. sandersi, with emphasis given to the unique features of the extension of the anterolateral angles of one or more of the anterior four pereonites, and the lack of a median cephalic projection. It is interesting to point out that out of the 10 species of this genus, eight are known from the south Atlantic (Lincoln, 1985a) while two species, C. sandersi sp. nov. and the high latitude species C. armadilloides (Hansen, 1916), are known only from the north Atlantic. Thus far, the genus does not include any species from the Indian Ocean, which is poorly explored for the presence of deep-sea isopods in general. However, the absence of the genus in the Pacific deep sea is remarkable since many haploniscid species are known from the south-east Pacific (Menzies and George, 1962) and from the north-west Pacific (Birstein, 1963).

description: This paper discusses the application of deep learning methods to highlight complex patterns in the feature space of recorded parameters of the information environment and the observed psychophysiological parameters to solve the problem of identifying potentially dangerous effects on operators of automated railway traffic control systems. The results of the application of multivariate analysis to experimental data in order to highlight the most informative features and subsequently train the neural network are described. The structure of a convolutional neural network is presented, which is potentially capable, within the framework of the deep learning paradigm, to generalize at different levels of the hierarchy the poorly formalized features that distinguish harmful media content that can affect the psyche and physiological state of users.

description: Patterning of graphene into micro- and nano-ribbons allows for the tunability in emerging fields such as flexible electronic and optoelectronic devices, and is gaining interest for the production of more efficient reinforcement for composite materials. In this work we fabricate micro-ribbons from CVD graphene by combining UV photolithography and dry etching oxygen plasma treatments. Raman spectral imaging confirms the effectiveness of the patterning procedure, which is suitable for large-area patterning of graphene on wafer-scale, and confirms that the quality of graphene remains unaltered. The produced micro-ribbons were finally transferred and embedded into a polymeric matrix and the mechanical response was investigated by in-situ mechanical investigation combining Raman spectroscopy and tensile/compressive tests.

(figure 11)
 Diagnosis. Chauliodoniscus with anterolateral angles of pereonites 2–4 produced and acute. Frontal margin of cephalon entire and straight. Posterior margin of pleotelson rounded and extending as far as the tip of the posterolateral projections. Flagellum of antenna 1 composed of five articles. Male pleopod 1 distally truncated. Uropod tip reaching to the tip of the posterolateral projections of the pleotelson.
 Material examined. Holotype: male, length 1.8 mm, width 0.7 mm. USNM Cat. No. 138671.
 Type locality. R / V Eastward Sta. G-5481 from the Carolina continental rise at site Sigma.
 Etymology. This new species is named in honour of Prof. Edward Wilson of Harvard University.
 Description of male. Body more than twice as long as wide, cephalon quadrate in shape. Cephalon about as long as the anterior two pereonites combined. First pereonite with rounded lateral margins and significantly shorter than the second. Pereonites 2–4 with acutely produced anterolateral angles. Lateral sutures between pereonites present but far more well-developed between pereonites 4 and 5. Pereonites 5–7 decreasing in length, the seventh being the shortest. Pleotelson shield-like with posterior margin rounded and reaching to the tips of the posterolateral projections.
Antenna 1 with two peduncular articles, article 2 longer and broader; flagellum of five articles, terminal article the longest and bearing a tuft of three long aesthetascs and four setae. Antenna 2 with a peduncle of four broad articles, article 4 broadest and foliaceous, flagellum composed of eight articles. Male pleopod 1 with truncated distal margin. Male pleopod 2 with a short and stout stylet. Uropod uniramous, tip reaching to the acute apex of the posterolateral projection of the pleotelson.
 Remarks. Chauliodoniscus wilsoni n. sp. is somewhat similar to C. quadrifrons (Menzies, 1962) from the Gulf of Guinea, off the Congo River and off Gabon, south Atlantic. In both species the cephalon is quadrate, article 5 of antenna 2 is not inflated and pereonites 2–4 have produced anterolateral angles. Nevertheless, the most striking difference is seen in the posterior aspect of the pleotelson, with the median margin and uropods extending to the tip of the posterolateral angles of pleotelson. Chauliodoniscus quadrifrons has setae on its lateral margins, but C. sandersi is devoid of lateral setae. Furthermore, the male first pleopod in this new species is truncated distally.

Corner transfer matrices of the Ising model in statistical mechanics

Year: 1979
Subjects: subject: Statistical mechanics

subject: Ising model

description: The work of this thesis is mainly on an investigation of the "corner transfer matrices" (CTM) of the Ising model in statistical mechanics. The thesis starts with a review on the Ising model and is followed by a brief discussion of various methods for investigating the Ising model. In particular, new techniques and approaches developed by Baxter form the basis for further research described in this thesis. Thus in Section I, the review is introduced first. In Section II, the new technique for investigating the zero field, eight-vertex model on the squ are lattice using the CTM suggested by Baxter (1976) is applied to the anisotropic, ferromagnetic, triangular Ising lattice in zero field below its critical temperature. The diagonal form of the CTM of the triangular lattice shows essentially the same structure as that for the square Ising lattice. The spontaneous magnetization can be obtained easily from this method. It is hoped that this technique will give illuminating insights into the problems of critical phenomena. In Section III, the variational approximation approach for the square lattice Ising model developed by Baxter (1978) is studied. The accuracy and rate of convergence of this approach is tested by applying the method to the zero field Ising model on the square lattice. The problem is simplified to that of solving a relatively small system of non-linear equations. The estimates to the spontaneous magnetization and the critical temperature from the sequence of variational approximations are obtained. The results converge rapidly to the exact ones. They exhibit a cross-over phenomenon and satisfy a scaling relationship for the spontaneous magnetization. Since this method can be applied to many systems such as the square lattice Ising model with a magnetic field, where the exact solution is not available yet, one may expect to obtain good approximations to the thermodynamic functions of these models by using this method.

description: The study of X-ray reprocessing is one of the key diagnostic tools to probe the environment in X-ray binary systems. One difficult aspect of studying X-ray reprocessing is the presence of much brighter primary radiation from the compact star together with the reprocessed radiation. In contrast for eclipsing systems, the X-rays we receive during eclipse are only those produced by reprocessing of the emission from the compact star by the surrounding medium. We report results from a spectral study of the X-ray emission during eclipse and outside eclipse (when available) in 9 high mass X-ray binaries (HMXBs) with XMM- Newton EPIC pn to investigate different aspects of the stellar wind in these HMXBs. During eclipse the continuum component of the spectrum is reduced by a factor of $\sim$8-237, but the count-rate for 6.4 keV Iron emission line or complex of Iron emission lines in HMXBs are reduced by a smaller factor leading to large equivalent widths of the Iron emission lines. This indicates a large size for the line emission region, comparable to or larger than the companion star in these HMXB systems. However there are significant system to system differences. 4U 1538$-$52, in spite of having a large absorption column density, shows a soft emission component with comparable flux during the eclipse and out-of-eclipse phases. Emission from Hydrogen-like Iron has been observed in LMC X-4 for the first time, in the out-of-eclipse phase in one of the observations. Overall, we find significant differences in the eclipse spectrum of different HMXBs and also in their eclipse spectra against out-of-eclipse spectra.

Subjects: Environmental Economics and Policy

description: Policy and regulatory decisions about the use of chemicals in food production and processing are unavoidable. However, scientific and economic information upon which to base these decisions is limited. At the same time many people have stakes in the benefits or costs associated with the use of these chemicals. Consumers are increasingly concerned that current regulations do not emphasize health risks sufficiently and give too much emphasis to current economic benefits from chemicals. Producers and food industry leaders are convinced that regulations protect consumers and that more stringent regulation in response to overstated health risks will result in higher food costs without improvements in health. Chemical manufacturers seek regulatrons that are consistent and uniform, and risk assessors and regulators argue that regulations should be undergirded with "good" science.

description: We calculate shifts and width of 1s and 2p states of pions bound to heavy nuclei, using an optical potential with its s-wave interaction part based on chiral symmetry. This potential is constructed systematically in two-loop approximation of chiral perturbation theory. A proper treatment of the explicit energy dependence of this potential in conjunction with gauge invariance turns out to be very important. Results are reported for deeply bound pionic states in Pb and Sn isotopes in comparison with the GSI data

description: Over the past year the Soviet agricultural system has been exposed to public scrutiny without the protection of traditional ideology and the selective use of statistics. The first set of efforts to change things-the much heralded leasing system-has had little impact, but the time for real change to occur has been very short. To date, the reforms are not clearly articulated. And there is no guarantee that they will succeed when and if implemented. However, spurred by increased food shortages and the general financial crises, Soviets and their politicians have little choice: the structure of agriculture must change. Whether agricultural reforms succeed or fail, the events of 1989 may be as momentous for the twenty-first century as the 1929 Soviet collectivization of their farms was for the twentieth.
Time-resolved ARPES and optical transport properties of irradiated twisted bilayer graphene in steady-state

description: We theoretically investigate the trARPES spectrum and optical Hall conductivity in periodically driven twisted bilayer graphene, considering both steady-state and "projected" occupations of the Floquet state. In periodically driven pre-thermalized systems, steady-state occupation of Floquet states is predicted to occur when coupled to a bath, while these states have projected occupation instantaneously after the driving starts. We study how these two regimes can give markedly different responses in optical transport properties. In particular, our results show that steady-state occupation leads to near-quantized optical Hall conductivity for a range of driving parameters in twisted bilayer graphene, whereas projected occupation leads to non-quantized values. We discuss the experimental feasibility of probing such non-equilibrium states in twisted bilayer graphene.

description: In Brazil, from the 2000s, the sugar-energy industry has grown. Between 2004 and 2009, ethanol sales increased 400%. However, between 2010 and 2014, a crisis settled in the sector, leading to the closure of several plants. Among the causes of the crisis, there was an anti-inflation control in the price of gasoline, which kept prices unchanged, reducing ethanol consumption intensely. This paper aims to verify the elasticity of demand for gasoline C and hydrated ethanol between 2004 and 2014 in Brazil. For this we used the cointegration vector and error correction model. The results indicated that the price elasticity and income elasticity of demand for both fuels are elastic. Therefore, it was concluded that the interference in gasoline prices and innovation of flex-fuel vehicles were the main factors that have altered the elasticity of demand for an elastic behavior in the short term. Not only, but also changes in the ethanol price caused more impact on gasoline demand than changes in the price of gasoline cause demand for ethanol.

description: As evidenced by a great number of works, it is common practice to assume that the Universe is flat. However, the majority of studies which make use of observational data to constrain the curvature density parameter are premised on the $Λ$CDM cosmology, or extensions thereof. On the other hand, fitting the data to models with a time-varying dark energy equation of state can, in some cases, accommodate a non-flat Universe. Several authors caution that if the assumption of spatial flatness is wrong, it could veer any efforts to construct a dark energy model completely off course, even if the curvature is in reality very small. We thus consider a number of alternative dynamical dark energy models that represent the complete cosmological scenario, and investigate the effects of spatial curvature on the evolution. We find that for a closed Universe, the transition to the epoch of decelerated expansion would be delayed with respect to the flat case. So would the start of the current dark energy-dominated era. This would be accompanied by a larger inflationary acceleration, as well as a larger subsequent deceleration. The opposite behavior is observed if the Universe is open.

description: The study of how neutron stars cool over time can provide invaluable insights into fundamental physics such as the nuclear equation of state and superconductivity and superfluidity. A critical relation in neutron star cooling is the one between observed surface temperature and interior temperature. This relation is determined by the composition of the neutron star envelope and can be influenced by the process of diffusive nuclear burning (DNB). We calculate models of envelopes that include DNB and find that DNB can lead to a rapidly changing envelope composition which can be relevant for understanding the long-term cooling behavior of neutron stars. We also report on analysis of the latest temperature measurements of the young neutron star in the Cassiopeia A supernova remnant. The 13 Chandra observations over 18 years show that the neutron star's temperature is decreasing at a rate of 2-3 percent per decade, and this rapid cooling can be explained by the presence of a proton superconductor and neutron superfluid in the core of the star.

description: In recent years, plant breeders' rights (PBR) has become a controversial subj ect worldwide. This paper reports the results of a survey of the seed distribution industries in the nine member countries of the International Union for the Protection of New Varieties of Plants (UPOV) as well as the seed trade in the United States (U.S . ) and Canada. The general consensus of the UPOV members was that PBR had resulted in increased private investment in plant breeding and that there had been a shift toward more basic research in the public sector. The findings in the U.S. were similar except that there the changes were perceived to be more crop specific with less funding available for public sector research. In Canada, the major concern centered around the potential effects of PBR legislation with strong arguments both for and against being put forward. The introduction of PBR into Canada would likely have neither strong positive nor strong negative economic effects on the grain and oilseeds sectors, particularly in the prairie grain growing region.

description: We present a new method for finding isolated exact solutions of a class of non-adiabatic Hamiltonians of relevance to quantum optics and allied areas. Central to our approach is the use of Bogoliubov transformations of the bosonic fields in the models. We demonstrate the simplicity and efficiency of this method by applying it to the Rabi Hamiltonian.
