description: Laser-induced manipulation of magnetism at the nanoscale is a rapidly growing research topic with potential for applications in spintronics. In this work, we address the role of the scattering cross section, thermal effects, and laser fluence on the magnetic, structural, and chemical stability of individual magnetic nanoparticles excited by single femtosecond laser pulses. We find that the energy transfer from the fs laser pulse to the nanoparticles is limited by the Rayleigh scattering cross section, which in combination with the light absorption of the supporting substrate and protective layers determines the increase in the nanoparticle temperature. We investigate individual Co nanoparticles (8 to 20 nm in size) as a prototypical model system, using x-ray photoemission electron microscopy and scanning electron microscopy upon excitation with single femtosecond laser pulses of varying intensity and polarization. In agreement with calculations, we find no deterministic or stochastic reversal of the magnetization in the nanoparticles up to intensities where ultrafast demagnetization or all-optical switching is typically reported in thin films. Instead, at higher fluences, the laser pulse excitation leads to photo-chemical reactions of the nanoparticles with the protective layer, which results in an irreversible change in the magnetic properties. Based on our findings, we discuss the conditions required for achieving laser-induced switching in isolated nanomagnets.

description: The objective of this paper is to analyse the matrix of technological capabilities of the sugar cane industry in Paraná State, showing your characteristic in the ambits of the investments, operation/production, innovation and relationships with the economy. The results of the matrix of technological capabilities show that the fact of not existing great concentrations for technological capabilities, for the advanced level, common in sugar cane industry, it is still derived of the secular subvencionist paradigm that reigned in the section until the nineties. However, the concern with the sectorial survival, mainly in the current deregulation ambient, it is also evidenced in several ambits of the technological capabilities portrayed by some sugar cane mills researched.

description: A pioneering experiment in Lambda hypernuclear spectroscopy, undertaken at the Thomas Jefferson National Accelerator Facility (Jlab), was recently reported. The experiment used the high- precision, continuous electron beam at Jlab, and a special arrangement of spectrometer magnets to measure the spectrum from {nat}C and 7Li targets using the (e,e' K+)reaction. The 12B hypernuclear spectrum was previously published. This experiment is now reported in more detail, with improved results for the 12B hypernuclear spectrum. In addition, unpublished results of the 7He hypernuclear spectrum are also shown. This later spectrum indicates the need for a more detailed few-body calculation of the hypernucleus and the reaction process. The success of this experiment demonstrates that the (e,e'K+) reaction can be effectively used as a high resolution tool to study hypernuclear spectra, ant its use should be vigorously pursued.

description: In spite of numerous philosophical papers concerning this topic, the philosophical approach of music criticism has not been carefully considered. For this purpose, I study in this paper the relationships between ontology of music and music criticism. A philosophical study of music criticism requires the lights of ontology of music, while music criticism is not devoid of ontological problems. The lessons and aporias of contemporary philosophical perspective on music criticism allow us to consider otherwise nineteenth century’s music criticism. It leads us to ask the following question: are we today facing an “ontological turn” in music criticism?

description: Bloch oscillations (BOs) are a fundamental phenomenon by which a wave packet undergoes a periodic motion in a lattice when subjected to an external force. Observed in a wide range of synthetic lattice systems, BOs are intrinsically related to the geometric and topological properties of the underlying band structure. This has established BOs as a prominent tool for the detection of Berry phase effects, including those described by non-Abelian gauge fields. In this work, we unveil a unique topological effect that manifests in the BOs of higher-order topological insulators through the interplay of non-Abelian Berry curvature and quantized Wilson loops. It is characterized by an oscillating Hall drift that is synchronized with a topologically-protected inter-band beating and a multiplied Bloch period. We elucidate that the origin of this synchronization mechanism relies on the periodic quantum dynamics of Wannier centers. Our work paves the way to the experimental detection of non-Abelian topological properties in synthetic matter through the measurement of Berry phases and center-of-mass displacements.

description: Exchange interactions in spin systems can give rise to quantum entanglement in the ground and thermal states of the systems. In this paper, we consider a spin tetramer, with spins of magnitude 1/2, in which the spins interact via nearest-neighbour, diagonal and four-spin interactions of strength J1, J2 and K respectively. The ground and thermal state entanglement properties of the tetramer are calculated analytically in the various limiting cases. Signatures of quantum phase transition (QPT) in terms of appropriate entanglement measures are obtained. The magnetic properties of a S = 1/2 AFM polyoxovanadate compound, V12, are well explained by spin tetramers with only nearest-neighbour exchange interactions. Treating the magnetic susceptibility chi as an entanglement witness (EW), an estimate of the lower bound of the critical entanglement temperature, T_c, above which the multipartite entanglement disappears in the experimental compound, is determined. A second EW based on energy provides an estimate of the entanglement temperature T_E, below which bipartite entanglement is certainly present in the system, is determined. The cases of the symmetric trimer and the tetrahedron are also considered.

Si les deux œuvres sont écrites dans des contextes différents, elles s’inscrivent néanmoins dans une vision téléologique de l’histoire où la vie de la pucelle est une répétition – dans les deux sens du terme – de la naissance de la nation américaine. Ces deux textes dressent en outre un portrait de Jeanne qui répond point par point à celui qu’en propose Shakespeare tout en ayant recours à la force légitimante du dramaturge élisabéthain.

description: Utilization of technology in agriculture makes it productive and promissing, contributing to its development. Investiments done by Govern of Ceará in agriculture have concentrate mainly on irrigated agriculture, through the agropoles, prevailing fruit-growing, banana being one of the chief crops. Banana crop performs an important role for cearense agriculture, however, it is generally characterized by low productivity, low technological level and large losses in production. The objective of this study was to measure the technological level of the irrigated banana crop in Agropole Cariri and to verify which are the factors conditioning the technological adoption. The calculated index showed that the technological index adopted in banana crop is classified as good. Technologies of irrigation and phytosanity have adoption level classified as optimum and the ones of the seedlings, adubation and cultural traits as good. Harvest and post-harvest technologies levels are classified as regular and the ones of management as insufficient. Socioeconomic variables such as technical assistence, banana crop as main activity, credit, scholarship, age, land owning, income, and place of dwelling contribute positively to increase the probability of producer to adopt the adequate technology in banana crop.

description: Isoparametric submanifolds and hypersurfaces in space forms are geometric objects that have been studied since E. Cartan. Another important class of geometric objects is the orbits of a polar action on a Riemannian manifold,e.g., the orbits of the adjoint action of a Lie group on itself. These two classes of submanifolds share comon properties. For example, they are leaves of a singular Riemannian foliation with sections (s.r.f.s. for short). The purpose of this paper is to review some results of the theory of s.r.f.s., which have been developed by the author. In addition, we give an alternative proof of Toeben's Theorem, who gave a necessary and sufficient condition for an equifocal submanifold to induce a s.r.f.s.

description: This paper presents the theoretical and empirical aspects of a monetary union between Brazil and Argentina based on the concept of Optimal Monetary Union. The behavior of some Brazilian and Argentinean macroeconomic indicators such as total debt, public deficit, interest rate and inflation rate have been analyzed. Symmetry analysis of economic cycles between these two countries was also done. Most Brazilian and Argentinean macroeconomic indicators have been divergent, probably due to the different monetary and exchange rate policies adopted by these two countries during the 90´s.The commercial integration analysis between Brazil and Argentina had detected a low level of commercial integration. Results also suggest that since 1998 there has been a divergent trend of a monetary area formation between these two countries. In other words, in the short run there has been high costs and low benefits associated to a single currency in Mercosur.

description: The main objective of this paper was to identify technical and sanitary requirements that could be qualified as export barriers for the Brazilian papaya and to quantify their effects on the volume exported to the United States of America. The methodology consisted of both qualitative and quantitative analysis. Qualitative information collected by means of interviews with producers and exporters were analyzed with the use of frequencies and descriptive statistics. A time series model of transfer function was estimated to analyze the impact of technical and sanitary barriers upon Brazilian papaya exports. Through the qualitative analysis it was possible to identify five technical and sanitary requirements that could be qualified as export barriers. Due to the lack of appropriate time series data, only two of them were subject to quantitative investigation. It was concluded that the Brazilian papaya exports have been negatively affected by these barriers and that this could be discussed bilaterally with the United States in the regular meetings of the Technical and Sanitary Barriers Committee.

The understanding of the preferences of the users of the transport services is important for the identification of the necessities and developments waited in the market. The relevant attributes had been raised under the bedding technician of the declared preference, in the form of ranking, using the method of confusing in the application of the cards to the shippers of grains in the state of the Paraná. The results had signaled for a significant concern with the fulfillment of contracts with customers and commitments in the ports and ships. As it could be evidenced, the shippers reflect the concern of the precariousness of the infrastructure, searching more guarantees of that the contracted service is fulfilled. As the attribute in the preference of the shippers was the performance consistency, that also has relation with these concerns, wanting to say that the given service must have a regular performance with small variance. These priorities of the shippers had guided in the elaboration of new strategies of act of contract of freights, looking for legalized rendering of service, with contractual relation.

description: Recent high precision experimental data for heavy-ion fusion reactions at subbarrier energies systematically show that a surprisingly large surface diffuseness parameter for a Woods-Saxon potential is required in order to fit the data. We point out that experimental data for quasi-elastic scattering at backward angles also favor a similar large value of surface diffuseness parameter. Consequently, a double folding approach fails to reproduce the experimental excitation function of quasielastic scattering for the $^{16}$O + $^{154}$Sm system at energies around the Coulomb barrier. We also show that the deviation of the ratio of the quasielastic to the Rutherford cross sections from unity at deep subbarrier energies offers an unambiguous way to determine the value of the surface diffuseness parameter in the nucleus-nucleus potential.

description: In the present work, we suggest an approach for describing dynamics of finite-dimensional quantum systems in terms of pseudostochastic maps acting on probability distributions, which are obtained via minimal informationally complete quantum measurements. The suggested method for probability representation of quantum dynamics preserves the tensor product structure, which makes it favourable for the analysis of multi-qubit systems. A key advantage of the suggested approach is that minimal informationally complete positive operator-valued measures (MIC-POVMs) are easier to construct in comparison with their symmetric versions (SIC-POVMs). We establish a correspondence between the standard quantum-mechanical formalism and the MIC-POVM-based probability formalism. Within the latter approach, we derive equations for the unitary von-Neumann evolution and the Markovian dissipative evolution, which is governed by the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) generator. We apply the MIC-POVM-based probability representation to the digital quantum computing model. In particular, for the case of spin-$1/2$ evolution, we demonstrate identifying a transition of a dissipative quantum dynamics to a completely classical-like stochastic dynamics. One of the most important findings is that the MIC-POVM-based probability representation gives more strict requirements for revealing the non-classical character of dissipative quantum dynamics in comparison with the SIC-POVM-based approach. Our results give a physical interpretation of quantum computations and pave a way for exploring the resources of noisy intermediate-scale quantum (NISQ) devices.

description: The traditional concept of work of art is articulated in three dimensions: work, text, and performance. Working on the recent musicological and aesthetical literature, the first part of the article highlights the relationship with time, from the point of view of the work (memory) and from that of the performance (flagrancy). In the second part, the conflict between both concurrent paradigms (text and performance) is reworked by means of analyzing performing arts like theater and sonic poetry. Adopting Alfred Gell’s concept of distributed object the act of performance together with its material traces is understood as social mediation of individual, historical agency.

That is, we impose that our universe has a pure dust configuration, and allow for a modification of gravity that yields a GCG specific scale factor evolution. Moreover, assuming that this new hypothetical gravity theory obeys a generalization of Birkhoff's law, we determine the Schwarzschild-like metric in this new modified gravity. We also study the large scale structure formation in this model. Both the linear and non-linear growth are studied together with the growth of the velocity fluctuation in the linear perturbation theory. We compare our results with those corresponding to the $Λ$CDM model and discuss possible distinguishable features.

It is found that the quark spectrum has a three-peak structure near Tc: We show that the additional new spectra originate from the mixing between a quark (anti-quark) and an anti-quark hole (quark hole) caused by a ``resonant scattering'' of the quasi-fermions with the thermally-excited soft modes.

description: This article looks for measuring and characterizing the milk’s agribusiness of Rio Grande do Sul economy. The methodology used indicators of sectorial performance and indexes of autonomy of purchases and sales to define the measure of the milk’s agribusiness. The data were extracted of the matrix input-output available by the Economy and Statistics Foundation (FEE) of the Rio Grande do Sul for the year 1998. It was verified that the state milk’s agribusiness answers, to basic price, for 6,77% of state’s agribusiness; it is strongly linked to the urban section in a direct way and it uses 118.603 workers, which employees 5,07% and 2,42% of the workers of the state’s agribusiness and state’s economy, respectively. Thus, it was concluded that the state milk’s agribusiness is constituted in an important component of the state’s agribusiness and the strong linkages that it presents are fundamental for the economic development of the state.

description: It is demonstrated that $ω^{-4/3}$ law of the power spectrum with the angular frequency $ω$ in dissipative flows is produced by the emission of dispersive waves from the antikink of an congested domain. The analytic theory predicts the spectrum is proportional to $ω^{-2}$ for relatively low frequency and $ω^{-4/3}$ for high frequency.

description: This special issue of "Aisthesis" explores the ways in which contemporary ontologies have helped to deepen our understanding of music in its various genres and forms of expression: oral, written, and phonographic. Besides investigating the evolution of the ontological status of musical objects in the light of the technological innovations occurred over the last century, the articles collected here investigate the relationship between ontology and aesthetics and address the question of the criteria for the identification and the evaluation of musical works, musical performances, and improvisations.

description: Major Atmospheric Gamma Imaging Cherenkov Telescopes (MAGIC) detected the gamma-ray afterglow of GRB 190114C, which can constrain microscopic parameters of the shock-heated plasma emitting non-thermal emission. Focusing on the early afterglow of this event, we numerically simulate the spectrum and multi-wavelength light curves with constant and wind-like circumstellar medium using a time-dependent code. Our results show that the electron acceleration timescale at the highest energies is likely shorter than 20 times the gyroperiod to reproduce the GeV gamma-ray flux and its spectral index reported by {\it Fermi}. This gives an interesting constraint on the acceleration efficiency for Weibel-mediated shocks. We also constrain the number fraction of non-thermal electrons $f_{\rm e}$, and the temperature of the thermal electrons. The early optical emission can be explained by the thermal synchrotron emission with $f_{\rm e} \lesssim 0.01$. On the other hand, the X-ray light curves restrict efficient energy transfer from protons to the thermal electrons, and $f_{\rm e}\sim1$ is required if the energy fraction of the thermal electrons is larger than $\sim10$\%. The parameter constraints obtained in this work give important clues to probing plasma physics with relativistic shocks.

description: We consider information transmission through a noiseless quantum channel, where the information is encoded into massive indistinguishable particles: bosons or fermions. We study the situation in which the particles are noninteracting. The encoding input states obey a set of physically motivated constraints on the mean values of the energy and particle number. In such a case, the determination of both classical and quantum capacity reduces to a constrained maximization of entropy. In the case of noninteracting bosons, signatures of Bose Einstein condensation can be observed in the behavior of the capacity. A major motivation for these considerations is to compare the information carrying capacities of channels that carry bosons with those that carry fermions. We show analytically that fermions generally provide higher channel capacity, i.e., they are better suited for transferring bits as well as qubits, in comparison to bosons. This holds for a large range of power law potentials, and for moderate to high temperatures. Numerical simulations seem to indicate that the result holds for all temperatures. Also, we consider the low temperature behavior for the three-dimensional box and harmonic trap, and again we show that the fermionic capacity is higher than the bosonic one for sufficiently low temperatures.

description: For many decades a major emphasis in public policy has been the assurance of food safety and security. Measurement of the economic returns to these programs is often difficult and challenging. In many cases the difficulty in obtaining data and the sheer complexity of the issues make the use of traditional econometric and programming approaches impractical for assessing these activities. This paper presents a summary of an innovative method for measuring benefits and costs of hard-to-assess programs and activities, such as those that deal with food safety, meat inspection and quality assurance. The building block approach described here for measuring benefits and costs was developed as an alternative method for measuring returns to meat inspection, agricultural grading, agricultural research and seed and seed potato quality assurance.
Why Superconducting Ta Qubits Have Fewer Tunneling Two-Level Systems at the Air-Oxide Interface Than Nb Qubits

description: Superconducting qubits are a key contender for quantum computing elements, but they often face challenges like noise and decoherence from two-level systems (TLS). Tantalum (Ta) qubits are notable for their long T$_1$ coherence times nearing milliseconds, mainly due to fewer TLS, though the cause was unclear. Our research explored this by analyzing the air-oxide interface with density functional theory, particularly comparing Nb oxide (Nb$_2$O$_5$) and Ta oxide (Ta$_2$O$_5$). We discovered that Ta$_2$O$_5$ forms a smoother surface with fewer dangling O atoms and TLS than Nb$_2$O$_5$. The greater atomic mass of Ta also lowers the TLS tunnel splittings below the qubit's operating frequency. Furthermore, using external electric fields or SO$_2$ passivation can significantly reduce TLS on Nb surfaces, potentially improving their coherence times.

description: Public wariness of genetically modified (GM) foods has led many nations to develop labelling policies for foods derived from modern agricultural biotechnology. In most cases mandatory labelling has been specified. In contrast, voluntary labelling is the chosen policy approach for the United States and Canada. Detailed regulations to enable a voluntary labelling policy to become effective in Canada have been time-consuming to develop. An even longer period of time has applied in the case of unsuccessful efforts to develop consensus standards for GM food labelling at the international level, through the processes of Codex Alimentarius.

description: International policy coordination is a challenging exercise requiring policy rapprochement among sovereign nations that often have very different political economy situations. Successful efforts may even result in the creation of multilateral paradigms such as trade agreements or multilateral environmental agreements (MEAs). Typically, there is overlap between these independent paradigms; sometimes in the nexus there is policy coordination and other times there is conflict. An understanding of the factors that account for coordination and conflict is crucial in ensuring that any benefits from policy coordination that may be achieved in one paradigm are not eroded through conflicts with another paradigm. This article presents a case study of the implications of overlapping multilateral paradigms – the World Trade Organization and an MEA known as the Cartagena Protocol on Biosafety – for international market access of biotechnology-based agri-food products.
The Star Clusters of the Small Magellanic Cloud: Age Distribution

description: We present age measurements for 195 star clusters in the Small Magellanic Cloud based on comparison of integrated colors measured from the Magellanic Clouds Photometric Survey with models of simple stellar populations. We find that the modeled nonuniform changes of cluster colors with age can lead to spurious age peaks in the cluster age distribution, that the observed numbers of clusters with age, t, declines smoothly as t^{-2.1}, that for an assumed initial cluster mass function scaling as M^{-2} the dependence of the cluster disruption time on mass is proportional to M^{0.48}, that despite the apparent abundance of young clusters the dominant epoch of cluster formation was the initial one, and that there are significant differences in the spatial distribution of clusters of different ages. Because of limited precision in our age measurements, we cannot address the question of detailed correspondence between the cluster age function and the field star formation history. However, this sample provides an initial guide for which clusters to target in more detailed studies of specific age intervals.

description: Electronic structures and optical excitations in Moebius conjugated polymers are studied theoretically. Periodic and Moebius boundary conditions are applied to the tight binding model of poly(para-phenylene), taking exciton effects into account. We discuss that oligomers with a few structural units are more effective than polymers for observations of effects of discrete wave numbers that are shifted by the change in boundary condition. Next, calculations of optical absorption spectra are reported. Certain components of optical absorption for an electric field perpendicular to the polymer axis mix with absorption spectra for an electric field parallel to the polymer axis. Therefore, the polarization dependences of an electric field of light enable us to detect whether conjugated polymers have the Moebius boundary.
