description: New coherent states may be induced by pertinently engineering the topology of a network. As an example, we consider the properties of non-interacting bosons on a star network, which may be realized with a dilute atomic gas in a star-shaped deep optical lattice. The ground state is localized around the star center and it is macroscopically occupied below the Bose-Einstein condensation temperature T_c. We show that T_c depends only on the number of the star arms and on the Josephson energy of the bosonic Josephson junctions and that the non-condensate fraction is simply given by the reduced temperature T/T_c.

description: AgReO4 microcalorimeters are planned to be used again in the next generation of calorimetric neutrino mass experiments with sensitivity down to 0.2 eV. The understanding and characterization of all possible sources of systematic uncertainties is crucial. In this work we focus on two of these sources, which have been studied in the 10 detectors of the Milano AgReO4 array experiment (MIBETA): a) the solid-state Beta Environmental Fine Structure (BEFS) observed for the first time in AgReO4; b) the detector energy response for internal beta events, which has been investigated with a dedicated measurement using a 44Ti gamma source. The possible effects on neutrino mass experiments due to the incomplete understanding of these two aspects are discussed.

description: We consider an ensemble of coupled oscillators whose individual states, in addition to the phase, are characterized by an internal variable with autonomous evolution. The time scale of this evolution is different for each oscillator, so that the ensemble is inhomogeneous with respect to the internal variable. Interactions between oscillators depend on this variable and thus vary with time. We show that as the inhomogeneity of time scales in the internal evolution grows, the system undergoes a critical transition between ordered and incoherent states. This transition is mediated by a regime of dynamical clustering, where the ensemble recurrently splits into groups formed by varying subpopulations.

description: Failure of controlled marketing and non-attainment of its goals necessitates market reform. It should be based on a holistic approach rather than selective deregulation that may enhance the protection of some groups and the concentrated market structure. Central considerations are motives for, and methods of, market reform. This paper evaluates privatisation and deregulation in the red meat industry and proposes alternatives. The current concentrated and vertically integrated market structure should be considered during the deregulation and the privatisation of ABACOR. A privatised ABACOR should be decoupled from regulatory protection, while appropriate regulation should secure consumer protection and fair business practices. A future role of the Meat Board in a deregulated red meat industry implies the absence of regulatory powers or group representation. Grading and hygiene standards should be decoupled from regulatory restrictions, should not be used to restrict entry into any marketing stage, be voluntary and based on free choice. Forward contracting and a futures market are possibilities in a reformed market, while market information services should be a function of the state. Successful market reform implies the absence of restrictive regulations, the promotion of competition, and performance judgement on the basis of consumer satisfaction.

description: Ce travail s’intéresse à une caractérisation à l’échelle locale de l’interphase ciment-granulat sain et dégradé thermiquement, puis, à terme, atteint de la pathologie de Réaction Sulfatique Interne (RSI). Cette caractérisation est réalisée à partir de plusieurs essais mécaniques associés à des mesures d’expansion et à des observations au microscope électronique à balayage (MEB). Les échantillons de forme parallélépipédique, dits composites, sont constitués d’une pâte de ciment liée à un granulat siliceux. La forme de ces échantillons permet de rendre plus accessible l’étude du comportement mécanique de l’interphase. Deux sens de coulage ont été effectués (horizontal et vertical). Dans une enceinte climatique permettant de réguler l’humidité relative proche de 100%, un cycle thermique a été appliqué aux échantillons au jeune âge avant qu’ils soient conservés dans de l’eau déminéralisée à 38°C. Les résultats montrent une expansion du composite plus importante que celle de la pâte de ciment après 28 jours de conservation. Suite au traitement thermique appliqué, la résistance à la traction du composite est plus affectée que celle du ciment où le sens de coulage lors de la préparation présente une incidence sur les résultats. Par ailleurs, des observations au MEB montrent que le sens de coulage et le traitement thermique modifient la microstructure de l’interphase ciment/granulat.

description: This Perspective examines the emerging applications of photonic topological insulators (PTIs) in the microwave domain. The introduction of topological protection of light has revolutionized the traditional perspective of wave propagation through the demonstration of backscatter-free waveguides in the presence of sharp bending and strong structural defects. The pseudospin degree of freedom of light enables the invention of unprecedented topological photonic devices with useful functionalities. Our aim is to present a brief introduction of recent developments in microwave PTI demonstrations. We give a clear comparison of different PTI realizations, summarize the key features giving rise to topological protection, and present a discussion of advantages and disadvantages of PTI technology compared to existing microwave device technology. We conclude with forward-looking perspectives of how the advantages of this technology can best be exploited.

description: We show that the one-way channel formalism of quantum optics has a physical realisation in electronic systems. In particular, we show that magnetic edge states form unidirectional quantum channels capable of coherently transporting electronic quantum information. Using the equivalence between one-way photonic channels and magnetic edge states, we adapt a proposal for quantum state transfer to mesoscopic systems using edge states as a quantum channel, and show that it is feasible with reasonable experimental parameters. We discuss how this protocol may be used to transfer information encoded in number, charge or spin states of quantum dots, so it may prove useful for transferring quantum information between parts of a solid-state quantum computer.

description: We report the results of measurements of $^{27}$Al and $^{55}$Mn NMR spectra, the related spin-lattice relaxation rates, and the dc magnetic susceptibility of the stable decagonal quasicrystal Al$_{69.8}$Pd$_{12.1}$Mn$_{18.2}$. The temperature-variation of the magnetic susceptibility $χ(T)$ reveals that the Mn ions carry only an average magnetic moment of approximately $2μ_{\mathrm{B}}$, and confirms a spin-glass type freezing of the Mn-moments at $T_f=12$K. The NMR spectra reveal two partially resolved lines for the $^{27}$Al-nuclei, indicating that there are two different sets of environments for the Al-sites. The integrated intensity of the Mn line in the spectra suggests that about half of the Mn ions carry no magnetic moment. Below 50K, and upon decreasing the temperature, the $^{27}$Al NMR-linewidth $w$ and the spin-lattice relaxation rate $T_1^{-1}$ both grow with an increasingly negative slope, as it is often observed and interpreted as a critical "slowing down" of magnetic moments in systems approaching a spin-glass transition. Various features, such as a broad maximum in $T_1^{-1}(T)$ and a slope change in the $w(χ)$ plot, both around 120K, suggest a gradual reduction of the number of Mn moments with decreasing temperature below 120K.

description: The Random Coupling Model (RCM) has been successfully applied to predicting the statistics of currents and voltages at ports in complex electromagnetic (EM) enclosures operating in the short wavelength limit. Recent studies have extended the RCM to systems of multi-mode aperture-coupled enclosures. However, as the size (as measured in wavelengths) of a coupling aperture grows, the coupling matrix used in the RCM increases as well, and the computation becomes more complex and time-consuming. A simple Power Balance Model (PWB) can provide fast predictions for the \textit{averaged} power density of waves inside electrically-large systems for a wide range of cavity and coupling scenarios. However, the important interference induced fluctuations of the wavefield retained in the RCM is absent in PWB. Here we aim to combine the best aspects of each model to create a hybrid treatment and study the EM fields in coupled enclosure systems. The proposed hybrid approach provides both mean and fluctuation information of the EM fields without the full computational complexity of coupled-cavity RCM. We compare the hybrid model predictions with experiments on linear cascades of over-moded cavities. We find good agreement over a set of different loss parameters and for different coupling strengths between cavities. The range of validity and applicability of the hybrid method are tested and discussed.

description: The recent resurgence of contracting in fisheries suggests a positive balance in the investment returns of contract fishers. Data were collected from 232 artisanal fishers (contracts, former and those that have never been in contract) for analysis. Results show that the fishermen differed in their investment layout with outboard engine taking highest investment capital of 57.9%, 59.8% and 49.9% for contract, former and non-contract fishers respectively. Variable costs of inputs of the fishers were N5929.13, N5488.4 and N4869.7 for former, contract and non-contract fishers respectively. Analysis of financial performance models of investment used showed that contract fishers had higher Return on Investment (ROI) (43.57%), Return on Assets (ROA) (22%), and Gross Margin (N4,345:00) than the former and those that have never been in contract before. However, Operating Profit Margin (OPM) was higher for former contract fishers (64.58%) seconded by non-contract fisher (60.84%) and tailed by contract fishers (56.89%). The study concluded that contract fishing gives higher returns compared to its best alternative.

description: This study assessed the effect of NGOs on alleviating poverty among rural farming households. A multi-stage sampling technique was used in selecting one hundred and fifty (150) NGO members and non-members respondent farmers in Ogun State from whom primary data were collected by means of a well structured questionnaire. The data collected include household size, age of the household head, income and NGO activities. The data was analyzed using descriptive statistics, Foster-Greer-Thorbecke (FGT) index and student-t test. Results revealed that household heads of both beneficiaries and non-beneficiaries’ farm families were predominantly males (90.6% and 73.9% respectively). The mean age of beneficiary and non-beneficiaries groups was 48 and 49 years respectively. More than 70% of both beneficiaries and non-beneficiaries farm household heads had access to formal education in one form or the other. About 23.4% of beneficiaries fell below the poverty line while 46.4% of non-beneficiaries fell below the line. Furthermore, poverty incidence was more prevalent among the non-beneficiaries’ (0.464) than the beneficiaries (0.234) while poverty was found to be severe among non-beneficiaries (40%) than beneficiaries (8%). A significant difference existed between the poverty conditions of beneficiaries and non-beneficiaries (p<0.01) farm households. Hence, it can be inferred that NGOs through their operations have improved the economic situation of their beneficiaries. Therefore, agriculture affiliated NGOs need to scale up their intervention programmes.

description: The Nigerian poultry value chain is growing fast and transforming alongside increased climate variability. However, despite its importance for livelihoods in Nigeria, there is limited information about how the Nigerian poultry subsector is affected by climate change. We use the conceptual framework of Reardon and Zilberman (2017), regarding climate shocks and change on transforming food supply chains to examine how climate change will affect Nigeria’s food economy. We propose hypotheses of the interactions between climate shocks and change and the dimensions of the poultry subsector. This exercise reveals that climate change will have heterogeneous effects on the different nodes of the country’s poultry value chain.

description: The identification of electromagnetic emission from gravitational-wave sources typically requires multiple follow-up observations due to the limited fields-of-view of follow-up observatories compared to the poorly localized direction of gravitational waves. Gravitational-wave localization regions are typically covered with multiple telescope pointings using a "honeycomb" structure, which is optimal only on an infinite, flat surface. Here we present a machine-learning algorithm which uses genetic algorithms along with Broyden-Fletcher-Goldfarb-Shanno (BFGS) optimization to find an optimal configuration of tiles to cover the gravitational-wave sky localization area on a spherical surface.

description: We explore the Dirac fermionic and complex scalar dark matter in the framework of a hidden $\mathrm{U}(1)_\mathrm{X}$ gauge theory with kinetic mixing between the $\mathrm{U}(1)_\mathrm{X}$ and $\mathrm{U}(1)_\mathrm{Y}$ gauge fields. The $\mathrm{U}(1)_\mathrm{X}$ gauge symmetry is spontaneously broken due to a hidden Higgs field. The kinetic mixing provides a portal between dark matter and standard model particles. Besides, an additional Higgs portal can be realized in the complex scalar case. Dark matter interactions with nucleons are typically isospin violating, and direct detection constraints can be relieved. Although the kinetic mixing has been stringently constrained by electroweak oblique parameters, we find that there are several available parameter regions predicting an observed relic abundance through the thermal production mechanism. Moreover, these regions have not been totally explored in current direct and indirect detection experiments. Future direct detection experiments and searches for invisible Higgs decays at a Higgs factory could further investigate these regions.

Le lien entre les propriétés des mousses aqueuses et la structure de mousse de chaux est étudié. La contribution de chaque type de porosité sur la conductivité thermique et la valeur de la capacité tampon hydrique (MBV) est déterminée, montrant l'intérêt de la maîtrise des conditions de moussage.

A Review of Methods for Estimating Algorithmic Complexity: Options, Challenges, and New Directions
Creators: name: Zenil, Hector
Publisher: name: arXiv
Year: 2020
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Some established and also novel techniques in the field of applications of algorithmic (Kolmogorov) complexity currently co-exist for the first time and are here reviewed, ranging from dominant ones such as statistical lossless compression to newer approaches that advance, complement and also pose new challenges and may exhibit their own limitations. Evidence suggesting that these different methods complement each other for different regimes is presented and despite their many challenges, some of these methods can be better motivated by and better grounded in the principles of algorithmic information theory. It will be explained how different approaches to algorithmic complexity can explore the relaxation of different necessary and sufficient conditions in their pursuit of numerical applicability, with some of these approaches entailing greater risks than others in exchange for greater relevance. We conclude with a discussion of possible directions that may or should be taken into consideration to advance the field and encourage methodological innovation, but more importantly, to contribute to scientific discovery. This paper also serves as a rebuttal of claims made in a previously published minireview by another author, and offers an alternative account.

description: RESUME. Un essai sur chaussées en vraie grandeur (APT : Accelerated Pavement Testing) est effectué par l’application du chargement contrôlé d’un poids lourd en utilisant un prototype d’une roue standard. Les essais à grande échelle avec Mobile Load Simulator (MLS10) sont présentés dans cet article. Une chaussée à paramètres contrôlés ou constants à l'intérieur d'un bâtiment isolé a été construite et soumise à un trafic contrôlé avec un total de 100 000 cycles d’une charge de 65 kN passant sur une période de 15 jours. Pour étudier le comportement de la chaussée tout au long de l'historique de chargement, la chaussée a été instrumentée avec différents capteurs. Cet article présente quelques analyses des résultats des essais réalisés par le simulateur de trafic ML10 dans le but d'étudier la performance de ce dernier et de déterminer la durée de vie des chaussées en service afin d'évaluer les mesures de maintenance.

description: We present an extended zero-field muon spin relaxation (ZF-$μ$SR) study of overdoped Bi$_{2+x}$Sr$_{2-x}$CaCu$_2$O$_{8+δ}$ (Bi2212) single crystals, intended to elucidate the origin of weak quasistatic magnetism previously detected by $μ$SR in the superconducting and normal states of optimally-doped and overdoped samples. New results on heavily-overdoped single crystals show a similar monotonically decreasing ZF-$μ$SR relaxation rate with increasing temperature that persists above the pseudogap (PG) temperature $T^*$ and does not evolve with hole doping ($p$). Additional measurements using an ultra-low background apparatus confirm that this behavior is an intrinsic property of Bi2212, which cannot be due to magnetic order associated with the PG phase. Instead we show that the temperature-dependent relaxation rate is most likely caused by structural changes that modify the contribution of the nuclear dipole fields to the ZF-$μ$SR signal. Our results for Bi2212 emphasize the importance of not assuming the nuclear-dipole field contribution is independent of temperature in ZF-$μ$SR studies of high-temperature (high-$T_c$) cuprate superconductors, and do not support a recent $μ$SR study of YBa$_2$Cu$_3$O$_{6+x}$ that claims to detect magnetic order in the PG phase.

description: Log-periodic oscillations have been used to predict price trends and crashes on financial markets. So far two types of log-periodic oscillations have been associated with the real markets. The first type are oscillations which accompany a rising market and which ends in a crash. The second type oscillations, called "anti-bubbles" appear after a crash, when the prices decreases. Here, we propose the third type of log-periodic oscillations, where a exogenous crash initializes a log-periodic behavior of market, and the market is growing up. Such behavior has been identified on Polish stock market index between the "Russian crisis" (August 1998) and the "New Economy crash" in April 2000.

description: La communauté scientifique reconnait l’effet de la variabilité spatiale des séismes. En effet, le mouvement du sol est spatialement et temporellement variable. Les causes principales de cette variabilité spatiale du mouvement sismique sont : l’effet d’incohérence, l’effet de passage d’ondes sismiques et particulièrement les conditions géologiques locales du site. Les structures étendues sont les plus concernées par ce phénomène de variabilité spatiale du mouvement sismique. La définition de l’input sismique qui sera appliqué à des structures étendues doit prendre en compte tous les causes de la variabilité spatiale du mouvement sismique. Ce travail vise à simuler des signaux sismiques spatialement variables en tenant en considération l’ensemble des causes de la variabilité spatiale des séismes. Un accent particulier est mis sur l’influence des conditions géologiques locales du site sur la représentation des excitations sismiques simulées. Une méthode de simulation des signaux sismiques spatialement variables est développée en se basant sur l’approche inconditionnelle. Cette dernière consiste à considérer que le mouvement sismique cible est défini par une densité spectrale de puissance. Un modèle d’incohérence empirique et l’effet de passage d’onde sont utilisés pour définir le mouvement sismique au substratum rocheux. La projection de ce mouvement sismique vers la surface est réalisée en adoptant l'effet d'amplification du site. Les résultats de ce travail ont montré que les mouvements sismiques spatialement variables sont conditionnés par la nature géologique du site étudié. En effet, l’action sismique est susceptible d’être amplifier tout dépend du type de site considéré.

description: The study determined the profitability of vegetable amaranth production along Jakara River in Kano Metropolis, Kano State, Nigeria. Multistage sampling technique was employed for the selection of one hundred and eighty (180) producers of Amaranth. Data were collected with the aid of questionnaire. The data collected were analysed using mean, standard deviation, coefficient of variability, net farm income and some financial ratios. The results of the study revealed that the producers of amaranth had a mean age of 38 years; mean household size of 7 individuals, mean years of education of 5; mean years of experience of 19 and mean income level of N460,567 per annum. Furthermore, Net farm income of N213,965 per hectare; Return to naira invested of 0.71; Gross ratio of 0.58 and operating ratio of 0.50 were all indicating that Amaranth production was a profitable venture. The study recommends that the producers should be patronizing input marketers that supply at relatively cheaper prices, through market survey, to enhance the profit level; and should also enrol in formal adult classes.

description: An empirical analysis of interest rates in money and capital markets is performed. We investigate a set of 34 different weekly interest rate time series during a time period of 16 years between 1982 and 1997. Our study is focused on the collective behavior of the stochastic fluctuations of these time-series which is investigated by using a clustering linkage procedure. Without any a priori assumption, we individuate a meaningful separation in 6 main clusters organized in a hierarchical structure.

description: Breast cancer is a common cancer for women. Early detection of breast cancer can considerably increase the survival rate of women. This paper mainly focuses on transfer learning process to detect breast cancer. Modified VGG (MVGG), residual network, mobile network is proposed and implemented in this paper. DDSM dataset is used in this paper. Experimental results show that our proposed hybrid transfers learning model (Fusion of MVGG16 and ImageNet) provides an accuracy of 88.3% where the number of epoch is 15. On the other hand, only modified VGG 16 architecture (MVGG 16) provides an accuracy 80.8% and MobileNet provides an accuracy of 77.2%. So, it is clearly stated that the proposed hybrid pre-trained network outperforms well compared to single architecture. This architecture can be considered as an effective tool for the radiologists in order to reduce the false negative and false positive rate. Therefore, the efficiency of mammography analysis will be improved.

description: In the context of string theory, several conjectural conditions have been proposed for low energy effective field theories not to be in swampland, the UV-incomplete class. The recent ones represented by the de Sitter and trans-Planckian censorship conjectures in particular seem to conflict with the inflation paradigm of the early universe. We first point out that scenarios where inflation is repeated several times (multi-phase inflation) can be easily compatible with these conjectures. In other words, we relax the constraint on the single inflation for the large scale perturbations to only continue at least around 10 e-folds. In this context, we then investigate if a spectator field can be a source of the almost scale-invariant primordial perturbations on the large scale. As a consequence of such an isocurvature contribution, the resultant perturbations exhibit the non-vanishing non-Gaussianity in general. Also the perturbation amplitude on smaller scales can be completely different from that on the large scale due to the multiplicity of inflationary phases. These signatures will be a smoking gun of this scenario by the future observations.

description: RESUME : La présente étude fait partie d’un projet de recherche initié sur la préservation des ressources naturelles habituelles de granulats en Algérie. Leur extraction devient de plus en plus abusive ces dernières années en rapport avec le développement des secteurs du génie civil et des travaux publics en particulier. Elle a pour objectif principal, la valorisation de nouveaux matériaux locaux naturels et le recyclage de matériaux industriels considérés comme déchets de façon à toucher rationnellement les deux volets économique et écologique. Elle se porte sur l’étude du comportement mécanique de mélanges de marne et de laitier cristallisé (déchet de haut fourneau) sous différentes sollicitations routières. Les résultats obtenus notamment pour les mélanges à forte proportions de laitier sont très intéressants et peuvent ouvrir un large éventail d’exploitation des matériaux cités. Ils peuvent ainsi présenter une alternative propre et rentable dans le domaine de la construction routière en particulier et éventuellement dans le domaine du génie civil en général.

Charge and Magnetization Inhomogeneities in Diluted Magnetic Semiconductors

description: It is predicted that III-V diluted magnetic semiconductors can exhibit stripe-like modulations of magnetization and carrier concentration. This inhomogeneity results from the strong dependence of the magnetization on the carrier concentration. Within Landau theory, a characteristic temperature T* below the Curie temperature is found so that below T* the equilibrium magnetization shows modulations, which are strongly anharmonic. Wavelength and amplitude of the modulation rise for decreasing temperature, starting from zero at T*. Above T* the equilibrium state is homogeneous, but the coupling between charge and magnetization leads to the appearance of an electrically charged layer in domain walls.
