description: In recent years, a number of preoccupations at the global, regional and national level have been aimed to find solutions to the current problems in the field of food consumption in children and young people, given the fact that both food insufficiency and food abuse generate negative effects on health. In Romania, the economic context consisting of the existence of a large number of children whose diet is insufficient made European programs for granting food in schools, during class hours, to be useful and to have social relevance. The article examines, starting from the Romanian legislative framework underpinning such programs, the coordinates of these efforts, concluding that they represent in the same time instruments of national food policy.

description: Vocal communication systems have a set of rules that govern the arrangement of acoustic signals, broadly defined as ‘syntax’. However, there is a limited understanding of potentially shared or analogous rules across vocal displays in different taxa. Recent work on songbirds has investigated syntax using network-based modelling. This technique quantifies features such as connectivity (adjacent signals in a sequence) and recurring patterns. Here, we apply network-based modelling to the complex, hierarchically structured songs of humpback whales (Megaptera novaeangliae) from east Australia. Given the song's annual evolving pattern and the cultural conformity of males within a population, network modelling captured the patterns of multiple song types over 13 consecutive years. Song arrangements in each year displayed clear ‘small-world’ network structure, characterized by clusters of highly connected sounds. Transitions between these connected sounds further suggested a combination of both structural stability and variability. Small-world network structure within humpback songs may facilitate the characteristic and persistent vocal learning observed. Similar small-world structures and transition patterns are found in several birdsong displays, indicating common syntactic patterns among vocal learning in multiple taxa. Understanding the syntactic rules governing vocal displays in multiple, independently evolving lineages may indicate what rules or structural features are important to the evolution of complex communication, including human language.

description: Paper aims at investigation of contemporary approaches to sustainable rural development in Russia with focus on predominantly non-rural areas, gravitationally attracted by such urban agglomerations, as Moscow. It includes the overview of current experiences in rural development, analysis of major economic and social indicators of rural areas in comparison with urban ones, characteristic of specific features of rural areas in Moscow Oblast, and elaboration of perspective ways to ensure sustainable development of those areas. Methods of benchmarking analysis, SWOT-analysis and program prognosis are implemented. The major results of the current research are discoveries of growth points for rural development and recommendations on perspective measures of state and local policies in rural areas, directed on increase of living standards of rural population and retention of labour resources in their traditional rural areas of inhabitation.

description: Mexico has become the sixth-largest dry chili exporter in the world and the largest chili (Capsicum annuum L) exporter, showing not only its production capacity but also giving it a decisive advantage over its main competitors. The aim of this paper is to describe the competitive structure and dynamics of chili exportations in Mexico over the period 1993- 2008. In order to compare the export growth performance with the performance of similar exporter countries, we look at the behavior of the Revealed Export Advantage index and the Constant Market Share Analysis. For all countries included in the analysis, the study considers the U.S as the objective market due to the current dry chili export market participation. The result suggests that Mexico occupies an important place in the global production but not a leadership place in exportations of dry chili at worldwide level.

description: New gauge bosons at the MeV scale with tiny gauge couplings (so-called dark photons) can be responsible for the freeze-in production of dark matter and provide a clear target for present and future experiments. We study the effects of thermal mixing between dark photons and Standard Model gauge bosons and of the resulting plasmon decays on dark matter production before and after the electroweak phase transition. In the parameter regions preferred by the observed dark matter relic abundance, the dark photon is sufficiently long-lived to be probed with fixed-target experiments and light enough to induce direct detection signals. Indeed, current limits from XENON1T already constrain Dirac fermion dark matter in the GeV to TeV range produced via the freeze-in mechanism. We illustrate our findings for the case of a $U(1)_{B-L}$ gauge extension and discuss possible generalisations.

description: We calculate the static and dynamic properties of single crystal, single molecule magnets consisting of equal spin $S=1/2$ or 5/2 dimers. The spins in each dimer interact with each other via the Heisenberg exchange interaction and with the magnetic induction ${\bf B}$ via the Zeeman interaction, and interdimer interactions are negligible. For antiferromagnetic couplings, the static magnetization and specific heat exhibit interesting low temperature $T$ and strong ${\bf B}$ quantum effects. We calculate the frequency spectrum of the Fourier transform of the real part of the time autocorrelation function ${\cal C}_{11}(t)$ for arbitrary $T, {\bf B}$, and compare our results with those obtained for classical spins. We also calculate the inelastic neutron magnetic dynamical structure factor $S({\bf q},ω)$ at arbitrary $T, {\bf B}$.

description: We investigate sufficient conditions for the presence of coexistence states for different genotypes in a diploid diallelic population with dominance distributed on a heterogeneous habitat, considering also the interaction between genes at multiple loci. In mathematical terms, this corresponds to the study of the Neumann boundary value problem \begin{equation*} \begin{cases} \, p_{1}''+λ_{1} w_{1}(x,p_{2}) f_{1}(p_{1}) = 0, &\text{in $Ω$,} \, p_{2}''+λ_{2} w_{2}(x,p_{1}) f_{2}(p_{2}) = 0, &\text{in $Ω$,} \, p_{1}'=p_{2}'=0, &\text{on $\partialΩ$,} \end{cases} \end{equation*} where the coupling-weights $w_{i}$ are sign-changing in the first variable, and the nonlinearities $f_{i}\colon\mathopen{[}0,1\mathclose{]}\to\mathopen{[}0,+\infty\mathclose{[}$ satisfy $f_{i}(0)=f_{i}(1)=0$, $f_{i}(s)>0$ for all $s\in\mathopen{]}0,1\mathclose{[}$, and a superlinear growth condition at zero. Using a topological degree approach, we prove existence of $2^{N}$ positive fully nontrivial solutions when the real positive parameters $λ_{1}$ and $λ_{2}$ are sufficiently large.

description: The present paper is a continuation of our work on curved finitary spacetime sheaves of incidence algebras and treats the latter along Cech cohomological lines. In particular, we entertain the possibility of constructing a non-trivial de Rham complex on these finite dimensional algebra sheaves along the lines of the first author's axiomatic approach to differential geometry via the theory of vector and algebra sheaves. The upshot of this study is that important `classical' differential geometric constructions and results usually thought of as being intimately associated with smooth manifolds carry through, virtually unaltered, to the finitary-algebraic regime with the help of some quite universal, because abstract, ideas taken mainly from sheaf-cohomology as developed in the first author's Abstract Differential Geometry theory. At the end of the paper, and due to the fact that the incidence algebras involved have been previously interpreted as quantum causal sets, we discuss how these ideas may be used in certain aspects of current research on discrete Lorentzian quantum gravity.

description: We derive and solve the full set of scalar perturbation equations for a class of $Z_2$-symmetric five-dimensional geometries generated by a bulk cosmological constant and by a 3-brane non-minimally coupled to a bulk dilaton field. The massless scalar modes, like their tensor analogues, are localized on the brane, and provide long-range four-dimensional dilatonic interactions, which are generically present even when matter on the brane carries no dilatonic charge. The shorter-range corrections induced by the continuum of massive scalar modes are always present: they persist even in the case of a trivial dilaton background (the standard Randall--Sundrum configuration) and vanishing dilatonic charges.

description: In 2+1 dimensions, QED becomes exactly solvable for all values of the fermion charge $e$ in the limit of many fermions $N_f\gg 1$. We present results for the free energy density at finite temperature $T$ to next-to-leading-order in large $N_f$. In the naive large $N_f$ limit, we uncover an apparently UV-divergent contribution to the vacuum energy at order ${\cal O}(e^6 N_f^3)$, which we argue to become a finite contribution of order ${\cal O}(N_f^4 e^6)$ when resumming formally higher-order $1/N_f$ contributions. We find the finite-temperature free energy to be well-behaved for all values of the dimensionless coupling $e^2N_f/T$, and to be bounded by the free energy of $N_f$ free fermions and non-interacting QED3, respectively. We invite follow-up studies from finite-temperature lattice gauge theory at large but fixed $N_f$ to test our results in the regime $e^2N_f/T\gg 1$.

The impact of star formation sampling effects on the spectra of lensed $z>6$ galaxies detectable with $\textit{JWST}$

description: The upcoming $\textit{James Webb Space Telescope}$ ($\textit{JWST}$) will allow observations of high-redshift galaxies at fainter detection levels than ever before, and $\textit{JWST}$ surveys targeting gravitationally lensed fields are expected to bring $z\gtrsim 6$ objects with very low star formation rate (SFR) within reach of spectroscopic studies. As galaxies at lower and lower star formation activity are brought into view, many of the standard methods used in the analysis of integrated galaxy spectra are at some point bound to break down, due to violation of the assumptions of a well-sampled stellar initial mass function (IMF) and a slowly varying SFR. We argue that galaxies with SFR$\sim 0.1\ M_\odot$ yr$^{-1}$ are likely to turn up at the spectroscopic detection limit of $\textit{JWST}$ in lensed fields, and investigate to what extent star formation sampling may affect the spectral analysis of such objects. We use the $\small{\text{SLUG}}$ spectral synthesis code to demonstrate that such effects are likely to have significant impacts on spectral diagnostics of, for example, the Balmer emission lines. These effects are found to stem primarily from SFRs varying rapidly on short ($\sim$ Myr) timescales due to star formation in finite units (star clusters), whereas the effects of an undersampled IMF is deemed insignificant in comparison. In contrast, the ratio between the HeII- and HI-ionizing flux is found to be sensitive to IMF-sampling as well as ICMF-sampling (sampling of the initial cluster mass function), which may affect interpretations of galaxies containing Population III stars or other sources of hard ionizing radiation.

description: This article aims to address violence as a public health issue, as violence threatens living conditions, work, interpersonal relationships, and is a complex reflection on violence and its various conditioning factors. In the Statute of Children and Adolescents, the highlight on health is present in article 7, stating that “children and adolescents have the right to protection of life and health through the implementation of public social policies that allow birth and development. healthy and harmonious, in conditions worthy of existence ”. Despite the classification of violence as a public health problem, the purpose of this paper, and the issue to be raised, is to question how schools can contribute to the prevention and combat of self-inflicted violence. With the advent of Law 13.819 / 19, which establishes the National Policy for the Prevention of Self-Harm and Suicide, the legislator provides, in article 6, item II and paragraph 5, that suspected or confirmed cases of self-harm are compulsory notification by the public and private schools to the Guardianship Council, as well as directing the schools to inform and train the professionals who work in its precincts regarding the notification procedures established by Law. The policies and programs implemented by the Ministries of Health and Education already perform this work in the current Brazilian scenario.

description: The research interest in mobile robots with independent steering wheels has been increasing over recent years due to their high mobility and better payload capacity over the systems using omnidirectional wheels. However, with more controllable degrees of freedom, almost all of the platforms include redundancy which is modeled using the instantaneous center of rotation (ICR). This paper deals with a Tetris inspired floor cleaning robot hTetro which consists of four interconnected differential-drive units, i.e., each module has a differential drive unit, which can steer individually. Differing from most other steerable wheeled mobile robots, the wheel arrangement of this robot changes because of its self-reconfigurability. In this paper, we proposed a robust path tracking controller that can handle discontinuous trajectories and sudden orientation changes. Singularity problems are resolved on both the mechanical aspect and control aspect. The controller is tested experimentally with the self-reconfigurable robotic platform hero, and results are discussed.

description: In a recent paper [Phys. Rev. B 66, 012501 (2002)], torque data measured on a MgB2 single crystal in fields from 10 to 60 kOe at 10 K were presented. The authors obtained the anisotropy gamma by fitting a theoretical expression to the data and concluded that the anisotropy is field independent gamma \approx 4.3. They also reported the observation of "intrinsic pinning", which they take as experimental evidence for the occurence of superconductivity in the boron layers. In this comment, we discuss the range of validity of the theoretical expression used by the authors and show that the conclusion of a field independent anisotropy does not hold. Furthermore, we present torque data measured on two crystals of MgB2, establishing the extrinsic nature of the peak in the irreversible torque observed in some crystals.

description: The early years of the post-socialist era saw the beginnings of massive regional and social differentiation in Hungary, which led to the emergence of three regional types. In the economic race there are those regions that develop vigorously, others that can be labelled as transition regions and still others that lag behind the first two. This holds true both for rural areas and the country as a whole. Rapidly developing rural areas lie in the vicinity of towns and cities with good employment opportunities, in favourable communication hubs, in resort areas or ones existing in isolation across the country. Rural areas lagging behind are invariably situated in regions that rely on heavy industry or only on largescale farming. The lecture discusses, in detail, a survey on a village community in a typical backward region, where the proportion of losers amounts to two-thirds of the local society. It also seeks to identify the causes of the social gap in Hungary's rural areas, to explain why they are trailing economically.

description: The absolute and relative decline of the rural population numbers is one of the most evident features of demographic development in Slovakia. The most intensive decline was observed during the period of extensive urbanization (1970—1985). The general political and socio-economic changes after 1989 significantly influenced and slowed-down the emigration processes from rural settlements to urban centres. This development has a deep impact on the basic demographic characteristics of the rural population in the country. The here presented evaluation of demographic changes of rural population in Slovakia accounts also for the national and regional dimension.

description: Chondrules are silicate spheroids found in meteorites, serving as important fossil records of the early solar system. In order to form chondrules, chondrule precursors must be heated to temperatures much higher than the typical conditions in the current asteroid belt. One proposed mechanism for chondrule heating is the passage through bow shocks of highly eccentric planetesimals in the protoplanetary disk in the early solar system. However, it is difficult for planetesimals to gain and maintain such high eccentricities. In this paper, we present a new scenario in which planetesimals in the asteroid belt region are excited to high eccentricities by the Jovian sweeping secular resonance in a depleting disk, leading to efficient formation of chondrules. We study the orbital evolution of planetesimals in the disk using semi-analytic models and numerical simulations. We investigate the dependence of eccentricity excitation on the planetesimal's size as well as the physical environment, and calculate the probability for chondrule formation. We find that 50 - 2000 km planetesimals can obtain eccentricities larger than 0.6 and cause effective chondrule heating. Most chondrules form in high velocity shocks, in low density gas, and in the inner disk. The fraction of chondrule precursors which become chondrules is about 4 - 9 % between 1.5 - 3 AU. Our model implies that the disk depletion timescale is $τ_\mathrm{dep}\approx 1~\mathrm{Myr}$, comparable to the age spread of chondrules; and that Jupiter formed before chondrules, no more than 0.7 Myr after the formation of the CAIs.

description: A phenomenological model is proposed to explain the recent observed cosmological variation of the fine structure constant as an effect of the quantum vacuum, assuming a flat universe with cosmological constant $Λ$ in the cases ($Ω_M, Ω_Λ$) equal to (0.3,0.7) and (1,0). Because of the fourth Heisenberg relation, the lifetime of the virtual pairs of the zero-point radiation must depend on the gravitational potential, so that the quantum vacuum changes its density and acquires a relative permittivity different from one. Since the matter was more concentrated in the past, the gravitational potential of all the universe was stronger and the optical density of the vacuum higher, the electron charge being then more renormalized and smaller than now. The model is based on a first order Newtonian approximation that is valid for the range of the observations, but not for very high redshift, its prediction being that $Δα/α$ is proportional to $Ω_M[a(t)^{-1}-1]-2Ω_Λ[a(t)^2-1]$, $a(t)$ being the scale factor. This agrees with the observations.

A QED Model for the Origin of Bursts from SGRs and AXPs

description: We propose a model to account for the bursts from soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) in which quantum electrodynamics (QED) plays a vital role. In our theory, that we term ``fast-mode breakdown,'' magnetohydrodynamic (MHD) waves that are generated near the surface of a neutron star and propagate outward through the magnetosphere will be modified by the polarization of the vacuum. For neutron star magnetic fields $B_\rmscr{NS} \gtrsim B_\rmscr{QED} \approx 4.4 \times 10^{13}$ G, the interaction of the wave fields with the vacuum produces non-linearities in fast MHD waves that can steepen in a manner akin to the growth of hydrodynamic shocks. Under certain conditions, fast modes can develop field discontinuities on scales comparable to an electron Compton wavelength, at which point the wave energy will be dissipated through electron-positron pair production. We show that this process operates if the magnetic field of the neutron star is sufficiently strong and the ratio of the wavelength of the fast mode to its amplitude is sufficiently small, in which case the wave energy will be efficiently converted into an extended pair-plasma fireball. The radiative output from this fireball will consist of hard X-rays and soft $γ$-rays, with a spectrum similar to those seen in bursts from SGRs and AXPs (abridged).

description: By using the updated improved Quantum Molecular Dynamics model in which a surface-symmetry potential term has been introduced for the first time, the excitation functions for fusion reactions of $^{40,48}$Ca+$^{90,96}$Zr at energies around the Coulomb barrier have been studied. The experimental data of the fusion cross sections for $^{40}$Ca+$^{90,96}$Zr have been reproduced remarkably well without introducing any new parameters. The fusion cross sections for the neutron-rich fusion reactions of $^{48}$Ca+$^{90,96}$Zr around the Coulomb barrier are predicted to be enhanced compared with a non-neutron-rich fusion reaction. In order to clarify the mechanism of the enhancement of the fusion cross sections for neutron-rich nuclear fusions, we pay a great attention to study the dynamic lowering of the Coulomb barrier during a neck formation. The isospin effect on the barrier lowering is investigated. It is interesting that the effect of the projectile and target nuclear structure on fusion dynamics can be revealed to a certain extent in our approach. The time evolution of the N/Z ratio at the neck region has been firstly illustrated. A large enhancement of the N/Z ratio at neck region for neutron-rich nuclear fusion reactions is found.

Machine-assisted Semi-Simulation Model (MSSM): Estimating Galactic Baryonic Properties from their Dark Matter using a Machine Trained on Hydrodynamic Simulations

description: We present a pipeline to estimate baryonic properties of a galaxy inside a dark matter (DM) halo in DM-only simulations using a machine trained on high-resolution hydrodynamic simulations. As an example, we use the IllustrisTNG hydrodynamic simulation of a $(75 \,\,h^{-1}{\rm Mpc})^3$ volume to train our machine to predict e.g., stellar mass and star formation rate in a galaxy-sized halo based purely on its DM content. An extremely randomized tree (ERT) algorithm is used together with multiple novel improvements we introduce here such as a refined error function in machine training and two-stage learning. Aided by these improvements, our model demonstrates a significantly increased accuracy in predicting baryonic properties compared to prior attempts --- in other words, the machine better mimics IllustrisTNG's galaxy-halo correlation. By applying our machine to the MultiDark-Planck DM-only simulation of a large $(1 \,\,h^{-1}{\rm Gpc})^3$ volume, we then validate the pipeline that rapidly generates a galaxy catalogue from a DM halo catalogue using the correlations the machine found in IllustrisTNG. We also compare our galaxy catalogue with the ones produced by popular semi-analytic models (SAMs). Our so-called machine-assisted semi-simulation model (MSSM) is shown to be largely compatible with SAMs, and may become a promising method to transplant the baryon physics of galaxy-scale hydrodynamic calculations onto a larger-volume DM-only run. We discuss the benefits that machine-based approaches like this entail, as well as suggestions to raise the scientific potential of such approaches.

Partial observables

Year: 2001
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We discuss the distinction between the notion of partial observable and the notion of complete observable. Mixing up the two is frequently a source of confusion. The distinction bears on several issues related to observability, such as (i) whether time is an observable in quantum mechanics, (ii) what are the observables in general relativity, (iii) whether physical observables should or should not commute with the Wheeler-DeWitt operator in quantum gravity. We argue that the extended configuration space has a direct physical interpretation, as the space of the partial observables. This space plays a central role in the structure of classical and quantum mechanics and the clarification of its physical meaning sheds light on this structure, particularly in context of general covariant physics.

description: Health is considered to be an extremely important component of human welfare. By the time India gained independence in 1947, achievement of good health had become an important national goal in its own right. Nevertheless, a vast public health infrastructure in India comprising of 145,000 Sub-centres, 23,000 Public Health Centres (PHCs) and 3222 Community Health Centres (CHCs) is estimated to be able to cater to only 20% of the Indian population. There have been numerous attempts to understand and analyze the causes underlying the failures of the health policies and thereby to provide meaningful solutions. While most of the earlier attempts to understand health look at the role of public and private institutions in the provision of health care, the focus of this paper is to identify the role that households play in determining their health status and the macroeconomic effects this decision can generate. The paper uses a CGE framework to simulate the effects of complete tariff liberalization in the presence / partial withdrawal / complete absence of health subsidy. Among major conclusions, this paper finds that complete subsidization of health reduces overall disparity by favoring rural households over urban. Withdrawal of health subsidy leads to domestic re-allocation of poverty pushing down the wage rates in agricultural sector, the main stay of rural households.

description: Models in which scalar field dark energy interacts with dark matter via a pure momentum coupling have previously been found to potentially ease the structure formation tension between early- and late-universe observations. In this article we explore the physical mechanism underlying this feature. We argue analytically that the perturbation growth equations imply the suppression of structure growth, illustrating our discussion with numerical calculations. Then we generalise the previously studied quadratic coupling between the dark energy and dark matter to a more general power law case, also allowing for the slope of the dark energy exponential potential to vary. We find that the structure growth suppression is a generic feature of power law couplings and it can, for a range of parameter values, be larger than previously found.
