description: Cosmic hydrogen reionization and cosmic production of first metals are major phase transitions of the universe occurring during the first billion years after the Big Bang, however these are still underexplored observationally. Using the JWST NIRSpec prism spectroscopy, we report the discovery of a sub-$L_\ast$ galaxy at $z_{\rm spec}=8.1623\pm0.0007$, dubbed RXJ2129-z8HeII, via the detection of a series of strong rest-frame UV/optical nebular emission lines and the clear Lyman break. RXJ2129-z8HeII shows a pronounced UV continuum with an extremely steep (i.e. blue) spectral slope of $β=-2.53_{-0.07}^{+0.06}$, the steepest amongst all spectroscopically confirmed galaxies at $z_{\rm spec}\gtrsim7$, in support of its very hard ionizing spectrum that could lead to a significant leakage of its ionizing flux. Therefore, RXJ2129-z8HeII is representative of the key galaxy population driving the cosmic reionization. More importantly, we detect a strong He II $λ$1640 emission line in its spectrum, one of the highest redshifts at which such a line is robustly detected. Its high rest-frame equivalent width (${\rm EW}=21\pm4$ Angstrom) and extreme flux ratios with respect to UV metal and Balmer lines raise the possibility that part of RXJ2129-z8HeII's stellar populations could be Pop III-like. Through careful photoionization modeling, we show that the physically calibrated phenomenological models of the ionizing spectra of Pop III stars with strong mass loss can successfully reproduce the emission line flux ratios observed in RXJ2129-z8HeII. Assuming the Eddington limit, the total mass of the Pop III stars within this system is estimated to be $7.8\pm1.4\times10^5 M_\odot$. To date, this galaxy presents the most compelling case in the early universe where trace Pop III stars might coexist with metal-enriched populations.

description: This paper has a two-fold contribution, 1) Examine the importance of aggregate economic policy on housing prices and rural housing prices, and 2) delineate factors resulting in divergent housing prices between urban and rural markets. Empirical application to US state level data from 1975-2006 indicates general economic variables are consistently influencing both urban and rural housing prices. While the farm economic variables do have differential influences on the housing and rural housing prices, their effects are transitory. Finally regional effects have greater impact on differential effects on urban rural housing price indexes than national farm programs.

description: This study examines how federal farm policies, specifically crop insurance, have affected the farm economic structure of North Dakota’s agriculture sector. The system of derived input demand equations is estimated to quantify the changes in North Dakota farmers’ input use when they purchase crop insurance. Further, the cumulative rolling regression technique is applied to capture the varying effects of the farm policies over time. Empirical results from the system of input demand functions indicate that there is no moral hazard since North Dakota farmers will increase fertilizer and pesticide use in the presence of crop insurance. Results also indicate that farmers in this state will not increase the use of land.

description: As many industries shift towards centralised controlled information systems for monitoring and control, more importance is being placed upon technologies such as Supervisory Control and Data Acquisitions industrial systems (SCADA). This focus on integration and interoperability presents numerous challenges for security personnel and organisational management alike. It becomes paramount therefore to reciprocate this new direction within an organisation with adequate plans and frameworks that ensure protection and security of its SCADA architecture. A clear understanding of the relevant threats and vulnerabilities is critical for adopting/developing appropriate policy and frameworks. To this end, in this research we identify and analyse relevant SCADA security threats and vulnerabilities and present a simple scheme to classify them for better understanding.

description: We show that classical DNA unzipping transition which is equivalently described by quantum mechanical localization-delocalization transition in the ground state of non-Hermitian single impurity Hatano-Nelson Hamiltonian is underpinned by generalized parity ({\bf P})-time reversal ({\bf T}) symmetry breaking transition. We also study the one-dimensional discretized version of Hatano-Nelson model in the presence of the single impurity and random disorder on a finite-size lattice. These discrete models are useful to study unzipping of a single adsorbed polymer from a surface. Our results show that the discrete models also undergo a phase transition from a PT unbroken phase to a broken phase. Interestingly, the generalized PT phase transition points coincide with the localization-delocalization transition for continuum as well as lattice models.

description: Lorsque Philippe II meurt en 1598, les plumes se délient pour participer collectivement au panégyrique attendu de l’excellence du souverain défunt. Ainsi, une diversité de moyens sont mobilisés pour donner à entendre et à voir ce que le pouvoir donne à penser de lui-même. L’établissement d’une représentation unique, répondant aux exigences temporelles de son saisissement, renouvelle de manière intensive la doxa politique instaurée pendant toute la durée du règne. Les sermons funèbres offrent un bon exemple d’une composition normée sur le plan formel et normative dans son propos. L’attitude du roi face à la mort l’érige en parangon absolu de la bonne mort chrétienne et vise, au-delà de l’exemplarité historique, à renforcer la norme tridentine dans le contexte politico-religieux du tournant du siècle. When Philippe II died in 1598, many writers took part to the collective eulogy that was to be made of the deceased sovereign. Various means were thus mobilised to show how the power was thought of. The setting of a unique representation, abiding to the temporal demands of its own creation, intensively renewed the political doxa that had been imposed on during the whole reign. Funeral orations are a good example of a creation that is both standardised in its form and normative in its content. The king’s attitude towards death made him the very paragon of the good Christian death and, beyond historical exemplarity, aimed at reinforcing the tridentine norme in the political and religious context of the turn of the century.

description: The Ouachita River Basin (ORB) in northeastern Louisiana accounts for almost 50 percent of the state’s agricultural production. In the Cabin-Teele Sub-watershed, within the ORB, the alkaline soils are naturally low in organic matter and deficient in nitrogen so that producers occasionally over apply nitrogen fertilizer. Moreover, because the soils are poorly drained there are drainage ditches throughout the fields and along field borders. The abundance of ditches enhances the outflow of nutrients and sediments into adjacent waterbodies. This study evaluated and compared the cost effectiveness of tillage and nutrient management practices at addressing specific sediment and nutrient criteria reductions; nitrogen, phosphorus and sediment reductions individually, and concurrently (reducing all three simultaneously) in Cabin-Teele Sub-watershed. Simulated results showed that reduced tillage, nitrogen management, and somewhat conservation tillage, were cost-effective in helping reduce nutrient and sediment losses in Cabin-Teele subwatershed despite the prevalence of poorly drained soils.

description: The Dijkgraaf-Vafa approach is used in order to study the Coulomb branch of the Leigh-Strassler massive deformation of N=4 SYM with gauge group U(N). The theory has N=1 SUSY and an N-dimensional Coulomb branch of vacua, which can be described by a family of ``generalized'' Seiberg-Witten curves. The matrix model analysis is performed by adding a tree level potential that selects particular vacua. The family of curves is found: it consists of order N branched coverings of a base torus, and it is described by multi-valued functions on the latter. The relation between the potential and the vacuum is made explicit. The gauge group SU(N) is also considered. Finally the resolvents from which expectation values of chiral operators can be extracted are presented.

description: In this paper, we propose a novel deep learning based approach for joint channel estimation and signal detection in orthogonal frequency division multiplexing (OFDM) systems by exploring the time and frequency correlation of wireless fading channels. Specifically, a Channel Estimation Network (CENet) is designed to replace the conventional interpolation procedure in pilot-aided estimation scheme. Then, based on the outcome of the CENet, a Channel Conditioned Recovery Network (CCRNet) is designed to recover the transmit signal. Experimental results demonstrate that CENet and CCRNet achieve superior performance compared with conventional estimation and detection methods. In addition, both networks are shown to be robust to the variation of parameter chances, which makes them appealing for practical implementation.

description: We study the implications of a noncommutative geometry of the minisuperspace variables for the FRW universe with a conformally coupled scalar field. The investigation is carried out by means of a comparative study of the universe evolution in four different scenarios: classical commutative, classical noncommutative, quantum commutative, and quantum noncommutative, the last two employing the Bohmian formalism of quantum trajectories. The role of noncommutativity is discussed by drawing a parallel between its realizations in two possible frameworks for physical interpretation: the NC-frame, where it is manifest in the universe degrees of freedom, and in the C-frame, where it is manifest through theta-dependent terms in the Hamiltonian. As a result of our comparative analysis, we find that noncommutative geometry can remove singularities in the classical context for sufficiently large values of theta. Moreover, under special conditions, the classical noncommutative model can admit bouncing solutions characteristic of the commutative quantum FRW universe. In the quantum context, we find non-singular universe solutions containing bounces or being periodic in the quantum commutative model. When noncommutativity effects are turned on in the quantum scenario, they can introduce significant modifications that change the singular behavior of the universe solutions or that render them dynamical whenever they are static in the commutative case. The effects of noncommutativity are completely specified only when one of the frames for its realization is adopted as the physical one. Non-singular solutions in the NC-frame can be mapped into singular ones in the C-frame.

description: This paper is intended to describe twistors via the paravector model of Clifford algebras and to relate such description to conformal maps in the Clifford algebra over R(4,1), besides pointing out some applications of the pure spinor formalism. We construct twistors in Minkowski spacetime as algebraic spinors associated with the Dirac-Clifford algebra, using one lower spacetime dimension than standard Clifford algebra formulations, since for this purpose the Clifford algebra over R{4,1} is also used to describe conformal maps, instead of R{2,4}. It is possible to identify the twistor fiber in four, six and eight dimensions, respectively, with the coset spaces SO(4)/(SU(2) x U(1)/Z_2) = CP1, SO(6)/(SU(3)x U(1)/Z_2) = CP3 and SO(8)/(Spin(6)x Spin(2)/Z_2). The last homogeneous space is closely related to the SO(8) spinor decomposition reserving SO(8) symmetry in type IIB superstring theory. Indeed, aside the IIB theory, there is no SO(8) spinor decomposition preserving SO(8) symmetry and, in this case, one can introduce distinct coordinates and conjugate momenta only if the Spin(8) symmetry is broken by a Spin(6) x Spin(2) subgroup of Spin(8). Also, it is reviewed how to generalize the Penrose flagpole, constructing a flagpole that is more general than the Penrose one, which arises in a particular case (Benn & Tucker description). We investigate the well-known relation between this flagpole and the SO(2n)/U(n) twistorial structure, which emerges when one considers the set X of all totally isotropic subspaces of C{2n}, and an isomorphism from the set of pure spinors to X. Finally we point out some relations between twistors fibrations and the classification of compact homogeneous quaternionic-Kahler manifolds (the so-called Wolf spaces), and exceptional Lie structures.

description: Recent agronomic research finds that economically optimal seeding densities have likely increased for many Midwestern corn farmers as a result of genetic improvements including new GM traits such as Bt corn and herbicide tolerance. We derive a per acre demand model for hybrid seed corn to examine the determinants of corn seeding densities and estimate the model using a large data set of individual farmer seed corn purchases. Current results identify factors other than prices affecting farmer corn seeding densities. Among these factors are the GM trait of the seed corn, measures of the local seed corn market structure, seed purchase source and intended end use. We interpret these effects in terms of information effects—farmers with more/better access to the latest agronomic research indicating that recommended seeding densities should be increased tend to plant corn at higher densities.

description: In this paper we show how to quantize Hopf solitons using the Finkelstein-Rubinstein approach. Hopf solitons can be quantized as fermions if their Hopf charge is odd. Symmetries of classical minimal energy configurations induce loops in configuration space which give rise to constraints on the wave function. These constraints depend on whether the given loop is contractible. Our method is to exploit the relationship between the configuration spaces of the Faddeev-Hopf and Skyrme models provided by the Hopf fibration. We then use recent results in the Skyrme model to determine whether loops are contractible. We discuss possible quantum ground states up to Hopf charge Q=7.

description: Mon propos est de montrer que la fabrique des calendriers répond à l’exigence d’imposer un rythme collectif à un groupe humain pour le réguler voire le dominer religieusement, socialement, politiquement. En prenant appui sur l’histoire des calendriers, je mettrai en évidence le fait que les prêtres et les rois se sont livrés une âpre bataille pour prendre la main sur la détermination des calendriers. Mais que signifie ce combat ? Pourquoi le pouvoir sur les calendriers est-il si convoité ? Ces questions me conduiront à réfléchir sur les rapports entre les calendriers et le temps. Le temps est-il lui aussi à penser comme un instrument au service de la norme ? Et même ce qu’il y a de plus intime en moi, ce qui conditionne et détermine la manière dont je pense ma vie, mon histoire et l’unité de mon moi, n’est-il pas lui-même conditionné par le temps social et les calendriers ? Ma conscience du temps n’est-elle pas elle-même régulée par le temps social du groupe auquel j’appartiens et par les calendriers qui l’expriment et qui régulent jours fériés, jours ouvrables, horaire d’été, horaire d’hiver. Le temps est individuel, le temps est social, le temps est même universel puisque le Temps Universel (TU) sert d’unité-étalon à tous les temps relatifs à la situation géographique d’un pays par rapport au méridien de Greenwich et pourtant cette omniprésence et omnipotence du temps n’est-elle pas une simple construction ? My goal is to prove that the point of producing calendars is to impose a rhythm on a human group in order to regulate and even to control it religiously, socially and politically. Basing itself on the history of calendars, my paper will make it plain that priests and kings fought each other over the power to determine calendars. But what did this struggle mean? Why was the power to control calendar creation so coveted? These questions are correlated to the problem of the relation between calendars and time. Is time also a tool for imposing norms to a group? And even what is most intimately ‘me’, the conditions of my life, my story and the unity of ego, are these also determined by social time and calendars? My awareness of time, isn’t it also regulated by the social time of the group to which I belong and by calendars which indicate holidays, working days, summer and winter time? Time is individual, time is social, time is even universal to the extent that local times all over the world are distinguished in reference to the Greenwich Meridian, and yet this omnipresence and omnipotence of time, isn’t it simply a construction?

Guaranteed efficient energy estimation of quantum many-body Hamiltonians using ShadowGrouping

description: Estimation of the energy of quantum many-body systems is a paradigmatic task in various research fields. In particular, efficient energy estimation may be crucial in achieving a quantum advantage for a practically relevant problem. For instance, the measurement effort poses a critical bottleneck for variational quantum algorithms.
 We aim to find the optimal strategy with single-qubit measurements that yields the highest provable accuracy given a total measurement budget. As a central tool, we establish new tail bounds for empirical estimators of the energy. They are helpful for identifying measurement settings that improve the energy estimate the most. This task constitutes an NP-hard problem. However, we are able to circumvent this bottleneck and use the tail bounds to develop a practical, efficient estimation strategy, which we call ShadowGrouping. As the name indicates, it combines shadow estimation methods with grouping strategies for Pauli strings. In numerical experiments, we demonstrate that ShadowGrouping improves upon state-of-the-art methods in estimating the electronic ground-state energies of various small molecules, both in provable and practical accuracy benchmarks. Hence, this work provides a promising way, e.g., to tackle the measurement bottleneck associated with quantum many-body Hamiltonians.

description: Smart meters enable remote and automatic electricity, water and gas consumption reading and are being widely deployed in developed countries. Nonetheless, there is still a huge number of non-smart meters in operation. Image-based Automatic Meter Reading (AMR) focuses on dealing with this type of meter readings. We estimate that the Energy Company of Paraná (Copel), in Brazil, performs more than 850,000 readings of dial meters per month. Those meters are the focus of this work. Our main contributions are: (i) a public real-world dial meter dataset (shared upon request) called UFPR-ADMR; (ii) a deep learning-based recognition baseline on the proposed dataset; and (iii) a detailed error analysis of the main issues present in AMR for dial meters. To the best of our knowledge, this is the first work to introduce deep learning approaches to multi-dial meter reading, and perform experiments on unconstrained images. We achieved a 100.0% F1-score on the dial detection stage with both Faster R-CNN and YOLO, while the recognition rates reached 93.6% for dials and 75.25% for meters using Faster R-CNN (ResNext-101).

description: The idea that individuals adapt their behaviors in response to changes in incentive systems is fundamental to most economic analysis. This paper incorporates the concept of price discovery costs into the incentive theory to offer a theoretical model and empirical evidence on the differential incentive effects of long-term contracts and spot markets. Using the US pork industry case where procuring intertemporally consistent weights of hogs have been critical to pork processors, we show why the effectiveness of unilaterally determined and posted incentive price for the hog quality by the pork packers on the intertemporal consistency erodes and why a bilateral incentive structure built through long-term hog procurement contracts is demanded, in the presence of volatile hog price and feed price movements. The MGARCH model analysis of USDA AMS data supported our hypotheses that long-term hog procurement contracts would help moderate the erosion relative to the spot markets, resulting greater intertemporal consistency of hog weights.

description: We have identified 85 regions of enhanced H-Alpha emission at |b| > 10 degrees subtending approximately 1 degree or less on the Wisconsin H-Alpha Mapper (WHAM) sky survey. These high latitude ``WHAM point sources'' have H-Alpha fluxes of 10^{-11} to 10^{-9} erg cm^-2 s^-1, radial velocities within about 70 km/s of the LSR, and line widths that range from less than 20 km/s to about 80 km/s (FWHM). Twenty nine of these enhancements are not identified with either cataloged nebulae or hot stars and appear to have kinematic properties that differ from those observed for planetary nebulae. Another 14 enhancements are near hot evolved low mass stars that had no previously reported detections of associated nebulosity. The remainder of the enhancements are cataloged planetary nebulae and small, high latitude H II regions surrounding massive O and early B stars.

description: The lack of a comprehensive statute to assist federal public servants in exposing wrongdoing within government has been a factor in the recent media attention focused upon the federal Privacy Commissioner. This has contributed, in large part, to his resignation from office. This incident highlights the complex relationships that exist for public servants who encounter and consider disclosing to the public wrongdoing within the federal government. This thesis is intended to contribute to the discussion of the issues involved in a public servant's duty of loyalty owed to the government and the confusion in the jurisprudence between whistle blowing and criticism of government policy. It investigates the scope of the Supreme Court of Canada's decision in Fraser v. Public Service Staff Relations Board and Federal Court, provincial appellate court, and administrative tribunal decisions that apply it. In particular, this thesis examines the relationships at law that underlay a theoretical foundation for those decisions. The relationship between whistle blowing and criticism of government policy by public servants as it relates to the common law duty owed by them to the government is examined. Consideration is also given to the role and extent that a civil servant's freedom of expression plays in shaping that duty of loyalty. Current government initiatives and proposed federal legislation are reviewed, since each establishes a different regime for addressing whistle blowing by federal public servants. An assessment of the current state of the common law and these initiatives from the perspective of law reform of this area of the law completes the discussion. The conclusion of this thesis is that the continuing confusion in the courts and administrative tribunals concerning separation of whistle blowing from government policy criticism is best addressed through the proposed federal legislative initiative. It seeks to create a regime that will adequately resolve the approach to adopt in relation to whistle blowing as a form of permissible organizational dissent by federal public servants in Canada.

description: The vertical gradient freeze crystal growth process is the main technique for the production of high quality compound semiconductors that are vital for today's electronic applications. A simplified model of this process consists of two 1D diffusion equations with free boundaries for the temperatures in crystal and melt. Both phases are coupled via an ordinary differential equation that describes the evolution of the moving solid/liquid interface. The control of the resulting two-phase Stefan problem is the focus of this contribution. A flatness-based feedforward design is combined with a multi-step backstepping approach to obtain a controller that tracks a reference trajectory for the position of the phase boundary. Specifically, based on some preliminary transformations to map the model into a time-variant PDE-ODE system, consecutive decoupling and backstepping transformations are shown to yield a stable closed loop. The tracking controller is validated in a simulation that considers the actual growth of a Gallium arsenide single crystal.

description: We calculate the momentum distribution and the second-order correlation function in momentum space, $g^{(2)}({\bf p},{\bf p}',t)$ for molecular dimers that are coherently formed from an ultracold atomic gas by photoassociation or a Feshbach resonance. We investigate using perturbation theory how the quantum statistics of the molecules depend on the initial state of the atoms by considering three different initial states: a Bose-Einstein condensate (BEC), a normal Fermi gas of ultra-cold atoms, and a BCS-type superfluid Fermi gas. The cases of strong and weak coupling to the molecular field are discussed. It is found that BEC and BCS states give rise to an essentially coherent molecular field with a momentum distribution determined by the zero-point motion in the confining potential. On the other hand, a normal Fermi gas and the unpaired atoms in the BCS state give rise to a molecular field with a broad momentum distribution and thermal number statistics. It is shown that the first-order correlations of the molecules can be used to measure second-order correlations of the initial atomic state.

description: In the Bulgarian flora, the genus Marrubium L. is represented by four species, of which M. frivaldskyanum is a rare species and Bulgarian endemic. The study presents information about the anatomy of leaves and stems of M. frivaldskyanum, collected from the floristic region of the Rhodopes Mts (western). The leaves show bifacial structure, with mesophyll which is differentiated as palisade and spongy parenchyma. The stomata are of anomocytic and diacytic types, located primarily on the abaxial epidermis. The leaf and stem surfaces are covered with two types of trichomes: non-glandular (unicellular and multicellular) and glandular. The cross-section of the stem represents the typical anatomy structure of dicotyledons. In terms of the shape, it is quadrangular, and collenchyma tissue can be seen under the epidermis in the area of the edges.

description: In order to achieve the climate targets, electrification of individual mobility is essential. However, grid integration of electrical vehicles poses challenges for the electrical distribution network due to high charging power and simultaneity. To investigate these challenges in research studies, the network-referenced supply task needs to be modeled. Previous research work utilizes data that is not always complete or sufficiently granular in space. This is why this paper presents a methodology which allows a holistic determination of residential supply tasks based on orthophotos. To do this, buildings are first identified from orthophotos, then residential building types are classified, and finally the electricity demand of each building is determined. In an exemplary case study, we validate the presented methodology and compare the results with another supply task methodology. The results show that the electricity demand deviates from the results of a reference method by an average 9%. Deviations result mainly from the parameterization of the selected residential building types. Thus, the presented methodology is able to model supply tasks similarly as other methods but more granular.

description: The study of the exchange of momentum and energy between wave components of the turbulent velocity field, the so-called triad interactions, offers a unique way of visualizing and describing turbulence. Most often, this study has been carried out by Direct Numerical Simulations or by power spectral measurements. Due to the complexity of the problem and the great range of velocity scales in high Reynolds number developed turbulence, direct measurements of the interaction between the individual wave components have been rare. In the present work, we therefore present measurements and related computer simulations of triad interactions between controlled wave components injected into an approximately laminar and uniform flow from an open wind tunnel by vortex shedding from two rods suspended into the flow. This well-defined vortex shedding approximates well a two-dimensional flow, which makes the analysis of the triadic interactions considerably less complex to analyze than in a fully developed spatially three-dimensional flow. With the information obtained from the simulations, we are hereby able to isolate and display the individual triad interactions taking place as the flow develops downstream as well as the strengths of these interactions. The experiments provide the time constants governing the development of higher order frequency components. The combination of these experiments and simulations provide unique insight into the inner workings of turbulence and shows how the nonlinear term in the Navier-Stokes equation on average forces the energy towards higher frequencies, which is the reason for the so-called energy cascade.

description: The paper investigates the difference in technical efficiency and in productivity change, and the technology gaps, between French and Hungarian farms in the dairy and cereal, oilseeds and proteinseeds (COP) sectors during the period 2001-2004. The analyses are performed with national FADN data and the Data Envelopment Analysis (DEA) approach under each country’s respective frontier and under a metafrontier. Results reveal that Hungarian farms’ technology was more productive, despite a technological deterioration. This suggests technological advantages for large-scale (Hungarian) over small-scale (French) farming. These findings may also be explained by the higher policy support in France.
Effective actions of a Gauss-Bonnet brane world with brane curvature terms

description: We consider a warped brane world scenario with two branes, Gauss-Bonnet gravity in the bulk, and brane localised curvature terms. When matter is present on both branes, we investigate the linear equations of motion and distinguish three regimes. At very high energy and for an observer on the positive tension brane, gravity is four dimensional and coupled to the brane bending mode in a Brans-Dicke fashion. The coupling to matter and brane bending on the negative tension brane is exponentially suppressed. In an intermediate regime, gravity appears to be five dimensional while the brane bending mode remains four dimensional. At low energy, matter on both branes couple to gravity for an observer on the positive tension brane, with a Brans-Dicke description similar to the 2--brane Randall-Sundrum setup. We also consider the zero mode truncation at low energy and show that the moduli approximation fails to reproduce the low energy action.

description: A new version of the nuclear shell model unifies the consideration of the discrete spectrum, where the results agree with the standard shell model, and continuum. The ingredients of the method are the non-Hermitian effective Hamiltonian, energy-dependent one-body and two-body decay amplitudes, and self-consistent treatment of thresholds. The results for helium and oxygen isotope chains well reproduce the data.
