description: It is shown that coherence resonance, a phenomenon in which regularity of noise-induced oscillations in nonlinear excitable systems is maximized at a certain optimal noise intensity, can be observed in quantum dissipative systems. We analyze a quantum van der Pol system subjected to squeezing, which exhibits bistable excitability in the classical limit, by numerical simulations of the quantum master equation. We first demonstrate that quantum coherence resonance occurs in the semiclassical regime, namely, the regularity of the system's oscillatory response is maximized at an optimal intensity of quantum fluctuations, and interpret this phenomenon by analogy with classical noisy excitable systems using semiclassical stochastic differential equations. This resonance persists under moderately strong quantum fluctuations for which the semiclassical description is invalid. Moreover, we investigate even stronger quantum regimes and demonstrate that the regularity of the system's response can exhibit the second peak as the intensity of the quantum fluctuations is further increased. We show that this second peak of resonance is a strong quantum effect that cannot be interpreted by a semiclassical picture, in which only a few energy states participate in the system dynamics.

description: The prevalence of non-monetary transactions (NMT) in the Ukrainian economy is a phenomenon attributable to its transition to a market system. Major types of NMT are barter transactions, offsets and payment in kind. Non-monetary transactions are widespread in agriculture. The aim of this research is to analyze the determinants, the nature and the economic effects of non-monetary transactions in Ukrainian agriculture. Based on actual conditions, the aim is to derive appropriate political and individual recommendations for leading the enterprises toward monetary transactions. For these purposes a theoretical framework is developed and the history of the phenomenon “barter”, as well as the institutional environment, are analyzed. Then follows a survey of 50 managers of agricultural enterprises in Oblast Kherson and an econometric analysis using panel data from these enterprises. The survey results and econometric estimations show that the main reason for non-monetary transactions is the liquidity problem of agricultural enterprises. Under the terms of soft budget constraints, the non-monetary transactions render possible the existence of illiquid enterprises in the market. In addition, the results show that the volume of NMT is decreasing due to liquidity improvement and a general improvement in the economic situation of agricultural enterprises. Based on the theory of money and transaction costs theory, monetary deals are more efficient than NMT, because of lower transaction costs due to the fact that money as a common medium of exchange reduces the problem of exchange partner search and mediates possible failures of the double coincidence of wants. This hypothesis is tested by econometric estimations using a panel data set of 50 agricultural enterprises in Oblast Kherson and is not rejected. The creation of a reliable institutional framework, the development of credit systems and the policy of hard budget constraints are important requirements for leading the enterprises toward monetary transactions. Agricultural producers have to realise that an improvement of profitability is only possible by using money as the medium of exchange in all transactions.

description: Ukrainian agriculture is currently in a growth phase, but it is yet not clear whether this growth is sustainable. The contrast between the potential of agricultural enterprises and their present desolate condition remains very striking. At the same time, the role of individual subsidiary holdings in agricultural production has increased substantially. The general economic crisis in agriculture encouraged growth in the number of individual subsidiary holdings (ISH) and made them the most important agricultural producers in Ukraine. The goals of this dissertation are (1) to analyse the development of organisational forms in Ukrainian agriculture, taking into account historical factors, (2) to determine differences between successful and unsuccessful enterprises, and (3) to determine the relationships (linkages) between ISHs and large agricultural enterprises. To fulfill the goals of the dissertation data from 78 large agricultural enterprises for 1995-1999 was examined. Moreover, in 2000 and 2002, 90 ISHs from 17 large agricultural enterprises were surveyed. The results of all interviews were summarized, including those that significantly deviated from the average, in order to present both norms and extremes. The study found a considerable divergence among restructured farm enterprises, both in terms of internal reorganisation and efficiency and in terms of managerial attitudes of new farm managers. Also various historical, economic and other reasons had an impact on the structure of reformed enterprises; these factors differ significantly by region in the Ukraine. These differences in agricultural development have their origins in property rights development as well as in differences of geopolitical position, and, therefore, in the influence of different cultures. The study emphasizes that in Ukraine there exists a clear tendency to establish agricultural enterprises with many owners and employees. The future development of large agricultural enterprises is entirely depended on setting up of adequate general economic conditions, consequential internal restructuring of agricultural enterprises and essential changes in the enterprise’s management. The efficiency of ISHs is very strongly affected by how and where they receive their production inputs. It may be expected that since there are no income alternatives and employment possibilities in the rural areas, the ISHs will continue to specialize in labor-intensive production such as livestock and vegetable production.
Inflation from $f(R)$ theories in gravity's rainbow

description: In this work, we study the $f(R)$ models of inflation in the context of gravity's rainbow theory. We choose three types of $f(R)$ models: $f(R)=R+α(R/M)^{n},\,f(R)=R+αR^{2}+βR^{2}\log(R/M^{2})$ and the Einstein-Hu-Sawicki model with $n,\,α,\,β$ being arbitrary real constants. Here $R$ and $M$ are the Ricci scalar and mass scale, respectively. For all models, the rainbow function is written in the power-law form of the Hubble parameter. We present a detailed derivation of the spectral index of curvature perturbation and the tensor-to-scalar ratio and compare the predictions of our results with the latest Planck 2018 data. With the sizeable number of e-foldings and proper choices of parameters, we discover that the predictions of all $f(R)$ models present in this work are in excellent agreement with the Planck analysis.

description: We perform null tests of the concordance model, using $H(z)$ measurements that mimic next-generation surveys such as Euclid and the SKA. To this end, we deploy a non-parametric method, so that we make minimal assumptions about the fiducial cosmology as well as the statistical analysis. We produce simulations assuming different cosmological models in order to verify how well we can distinguish between their signatures. We find that SKA- and Euclid-like surveys should be able to discriminate sharply between the concordance and alternative dark energy models that are compatible with the Planck CMB data. We conclude that SKA and Euclid will be able to falsify the concordance model in a statistically significant way, if one of the benchmarks models represents the true Universe, without making assumptions about the underlying cosmology.

Propylea Mulsant, 1846: 147, 152.
Type species: Coccinella quatuordecimpunctata Linnaeus, 1758, by monotypy.
Oenopia (Pania) Mulsant, 1850: 420. Type species: Oenopia (pania) luteopustulata Mulsant, by subsequent designation of Iablokoff-Khnzorian 1979.—Synonymized by Vandenberg & Gordon 1991: 32.
Pania: Iablokoff-Khnzorian 1979: 58; 1982: 121.
Diagnosis. Form oblong oval, convex. Inner margin of eyes more or less straight, interocular distance more than twice the eye width. Antenna with terminal antennomere rather elongate and oval-shaped. Anterior inner corners of prothoracic hypomera with a deep, oval impression / fovea to accommodate the antennal club. Anterior margin of mesoventrite with a deep, V-shaped median emargination. Abdominal postcoxal line incomplete without an associated line. Female genitalia with much reduced and short styli, infundibulum in the form of a lightly sclerotized piece of bursa at origin of sperm duct; spermatheca with poorly differentiated ramus and nodulus.
Distribution. Mainly distributed in the Palaearctic and Oriental region.
Affinities. Propylea is a distinctive genus and Tomaszewska et al. (2021) placed it in the Synonycha- group of genera and recovered it in a strongly supported clade comprising Alloneda and Coelophora (in part).
Included species. Three species, Propylea quatuordecimpunctata (Mulsant), P. dissecta (Mulsant), and P. luteopustulata (Mulsant), are found in this region, the first being rare and apparently confined to the colder parts of northwestern region. Propylea japonica (Thunberg) has been reported from India but remains an unverified record for mainland India. The species of Propylea are somewhat similar in external appearance and the elytral pattern is often highly variable. The nominate forms of P. japonica, P. dissecta, and P. quatuordecimpunctata, have a characteristic yellow and black ‘checkerboard pattern’ on the elytra. The male genitalia are also very similar, with only small differences and need to be studied for accurate diagnosis.

description: Marketing co-operatives can strengthen countervailing power of producers and help to co-ordinate (agricultural) supply chains. According to many authors, one of the means of increasing the competitiveness of co-ops can be traced back to trust and informal connections existing between the members and the cooperative (management), as well as among the members. Using New Institutional Economics’ theories and the “co-operative identity” concept as theoretical background, this review paper analyses the importance of trust, as well as the role of the co-operative principles as formal-legal securities of trust (development) in agricultural marketing co-operatives.

Coccinella tetraspilota Hope, 1843: 64 (nec Coccinella tetraspilota Hope, 1831).—Booth & Pope 1989: 366.
Diagnosis. Length: 3.00– 4.70 mm; width: 2.40–3.20 mm. Form elongate oval, moderately convex. Ground colour creamy yellow to yellow with black maculae on pronotum and elytra. Pronotum yellow, with a large transverse median black marking reaching hind margin. Elytral pattern variable as in P. dissecta, with an anchor-shaped macula (Fig. 175a, b) that is variously reduced with only a black spot on humeral callus on each elytron and an anteriorly broader stripe along sutural line (or) completely yellow with only a sutural black stripe. Abdominal ventrites medially black, abdominal postcoxal line (Fig. 175c) incomplete. Female genitalia (Fig. 175d) and spermatheca (Fig. 175e) as illustrated.
It can be differentiated from Propylea dissecta (Mulsant) by its more oblong and distinctly narrower body outline with less explanate elytral margins, usually smaller size and the male genitalia. The periscutellar yellow spots are usually elongate and subrectangular in P. japonica compared to the elongate oval shaped spots in P. dissecta.
Distribution.? India; Southeast Asia (Vietnam, Laos, China, Japan, Korea). As mentioned earlier, records of P. japonica from mainland India appear to be suspect or mainly based on wrong identification of P. dissecta.
Prey/associated habitat. Primarily aphidophagous, recorded as a predator of numerous hosts.
Notes. I have never examined P. japonica from mainland India and it is most likely to be distributed in the remote parts of northeastern India that remain poorly explored. Sasaji (1971) has given a detailed description and Ren et al. (2009) also illustrated it.

description: This work was aimed at analysing the effects of the sudden food price explosion followed by price crash which occurred recently on the foreign trade of the food economy. Comparison of the balances of the different countries was difficult due to the differences in the absolute dimensions; therefore a new method was introduced. Firstly, with the help of the “food economic foreign trade profile” extent to which the different product categories (divided by main product groups or by degree of processing) contribute to the foreign trade balance of the given country’s food economy was examined. In the second step, with the help of “profile indexing”, the extent to which the country in question was able to turn to profit the market opportunities offered by the price boom was demonstrated numerically. It can be stated that the foreign trade of the Hungarian food economy is amongst the winners of the price explosion. The balance improved remarkably between the two periods because exports of cereals and oilseeds increased greatly due to the increasing market prices during 2007 and 2008. As regards the performance of the other sectors, Hungary can be however ranked among the losers as a consequence of the decreasing international competitiveness of the production. The assessment has also demonstrated that some of Hungary’s direct competitors (e.g. the Netherlands and Germany) were able to make better use of the opportunities.
Dynamics and Thermodynamics of the Glass Transition

description: The principal theme of this paper is that anomalously slow, super-Arrhenius relaxations in glassy materials may be activated processes involving chains of molecular displacements. As pointed out in a preceding paper with A. Lemaitre, the entropy of critically long excitation chains can enable them to grow without bound, thus activating stable thermal fluctuations in the local density or molecular coordination of the material. I argue here that the intrinsic molecular-scale disorder in a glass plays an essential role in determining the activation rate for such chains, and show that a simple disorder-related correction to the earlier theory recovers the Vogel-Fulcher law in three dimensions. A key feature of this theory is that the spatial extent of critically long excitation chains diverges at the Vogel-Fulcher temperature. I speculate that this diverging length scale implies that, as the temperature decreases, increasingly large regions of the system become frozen and do not contribute to the configurational entropy, and thus ergodicity is partially broken in the super-Arrhenius region above the Kauzmann temperature $T_K$. This partially broken ergodicity seems to explain the vanishing entropy at $T_K$ and other observed relations between dynamics and thermodynamics at the glass transition.

Mechanisms underlying the decline of mountain caribou (Rangifer tarandus caribou) in British Columbia
Creators: name: Wittmer, Heiko Uwe
Publisher: name: University of British Columbia
Year: 2009

description: The distribution and abundance of mountain caribou (Rangifer tarandus caribou) in British Columbia has declined. High predation rates as a consequence of forest management and associated changes to the relative abundances of alternate ungulate prey species have been proposed to cause the population declines. A direct link between changes in the forest age structure and declining caribou population trends, however, is lacking. Understanding the underlying mechanism of the population decline is necessary to develop recovery strategies aimed at maintaining a viable mountain caribou population. I synthesized demographic and radiotelemetry data from separate studies initiated over the entire distribution of mountain caribou between 1984 and 2002. My primary goal was to use a comparative approach among identified subpopulations to distinguish between three potential repercussions of forest management (food regulation, predation-sensitive foraging, and predation) that might explain the observed declining population trends. I used information on caribou density per area of forests >140 years within subpopulation ranges and cause of mortality to differentiate between the potential repercussions. Predation was the primary cause of caribou mortality over the entire distribution of mountain caribou. In addition, I found increasingly negative rates of increase as caribou density per area of forests >140 years declined (i.e. inverse density dependence). Both results were consistent with the hypothesis that the decline of mountain caribou is caused by high predation rates. I then quantified the influence of demographic parameters on subpopulation trends and identified environmental factors correlated with variation in these demographic parameters among subpopulations. My results indicated that differences in subpopulation trends were best explained by differences in female adult survival rates. Female adult survival rates were negatively associated with increasing amounts of young forest stands and thus high proportions of suitable habitat for alternate prey species. Thus, my data supports the mechanistic link between the amount of habitat characteristics suitable for alternate ungulates and decreased survival of adult female caribou. Finally, I carried out a population viability analysis for mountain caribou. My results indicate that mountain caribou are likely declining to extinction over the majority of their distribution within <100 years.

description: The problem of the electrostatics in conical wormholes is revisited, now improving the background geometries with asymptotical flatness. The electric self-force on a point charge placed at different regions in the spacetime of a conical thin-shell wormhole connecting flat outer submanifolds is obtained and compared with the results of previous works. The study is also carried out in terms of a previously introduced analogy in which the effect of the matter shells on the electric field is reproduced by non-gravitating layers of charge located on the boundary surfaces. Besides, a better insight on the physical effects of a non trivial topology is obtained by means of a further analysis of the electric fluxes across the wormhole throat and at both spatial infinities. It is found that the throat is traversed by a non-arbitrary and finite topological flux, proportional to the charge of the source, which is characteristic of the asymptotically flat cylindrical wormholes regardless of the details of the throat geometry.

description: Constrained IoT devices are becoming ubiquitous in society and there is a need for secure communication protocols that respect the constraints under which these devices operate. EDHOC is an authenticated key establishment protocol for constrained IoT devices, currently being standardized by the Internet Engineering Task Force (IETF). A rudimentary version of EDHOC with only two key establishment methods was formally analyzed in 2018. Since then, the protocol has evolved significantly and several new key establishment methods have been added. In this paper, we present a formal analysis of all EDHOC methods in an enhanced symbolic Dolev-Yao model using the Tamarin tool. We show that not all methods satisfy the authentication notion injective of agreement, but that they all do satisfy a notion of implicit authentication, as well as Perfect Forward Secrecy (PFS) of the session key material. We identify other weaknesses to which we propose improvements. For example, a party may intend to establish a session key with a certain peer, but end up establishing it with another, trusted but compromised, peer. We communicated our findings and proposals to the IETF, which has incorporated some of these in newer versions of the standard.

description: An impact parameter representation for soft gluon radiation is applied to obtain both the initial decrease of the total cross-section ($σ_{tot}$) for proton-proton collisions as well as the later rise of $σ_{tot}$ with energy for both $pp$ and $p\bar{p}$. The non-perturbative soft part of the eikonal includes only limited low energy gluon emission and leads to the initial decrease in the proton-proton cross- section. On the other hand, the rapid rise in the hard, perturbative jet part of the eikonal is tamed into the experimentally observed mild increase by soft gluon radiation whose maximum energy rises slowly with energy.

description: Crossmodal correspondences are defined as associations between crossmodal stimuli based on seemingly irrelevant stimulus features (i.e., bright shapes being associated with high-pitched sounds). There is a large body of research describing auditory crossmodal correspondences involving pitch and volume, but not so much involving auditory timbre, the character or quality of a sound. Adeli and colleagues (2014, Front. Hum. Neurosci. 8, 352) found evidence of correspondences between timbre and visual shape. The present study aimed to replicate Adeli et al.’s findings, as well as identify novel timbre–shape correspondences. Participants were tested using two computerized tasks: an association task, which involved matching shapes to presented sounds based on best perceived fit, and a semantic task, which involved rating shapes and sounds on a number of scales. The analysis of association matches reveals nonrandom selection, with certain stimulus pairs being selected at a much higher frequency. The harsh/jagged and smooth/soft correspondences observed by Adeli et al. were found to be associated with a high level of consistency. Additionally, high matching frequency of sounds with unstudied timbre characteristics suggests the existence of novel correspondences. Finally, the ability of the semantic task to supplement existing crossmodal correspondence assessments was demonstrated. Convergent analysis of the semantic and association data demonstrates that the two datasets are significantly correlated (−0.36) meaning stimulus pairs associated with a high level of consensus were more likely to hold similar perceived meaning. The results of this study are discussed in both theoretical and applied contexts.

description: In this study, a scalar field propagating in a higher-dimensional Reissner-Nordström-de Sitter black hole is investigated. Scalar fields are assumed to have non-minimal coupling to the brane or bulk scalar curvature. Five different {definitions} of black hole temperatures are discussed: temperature based on surface gravity, Bousso-Hawking temperature, and three effective temperatures. The greybody factors of minimally and non-minimally coupled scalar fields on the brane and in the bulk are examined under the effect of particle and spacetime properties. The energy emission spectra of black holes are determined at various temperatures for both the brane and bulk channels. The energy emission rates at the Bousso-Hawking temperature are found to be dominant over those at other temperatures. The energy emission curves are suppressed by the presence of coupling parameters. Finally, the bulk-over-brane emission ratios are calculated. Notably, bulk dominance becomes possible for a certain definition of the temperatures and regime of the cosmological constant.

High spatial resolution mid-infrared spectroscopy of NGC 5253: The stellar content of the embedded super-star cluster

description: We present the N-band (8-13 micron) spectrum of the hidden compact radio super-star cluster in NGC 5253, C2, obtained with TIMMI2 on the ESO 3.6m telescope. The spectrum is characterised by a rising continuum due to warm dust, a silicate absorption and a strong [SIV] line at 10.5 micron. Weaker lines of [ArIII] at 9.0 micron and [NeII] at 12.8 micron are also present. The continuum can be modeled by an optically thick emission from hot dust emission extinguished by a cold foreground dust screen and a silicate absorption feature with A_sil = 0.73+/-0.05 mag. We show how the spatial scale of the observations greatly determine the mid-IR appearance of NGC 5253 and the important implications that this has on the interpretation of line fluxes in terms of the properties (age, IMF, etc.) of the embedded cluster. We have modeled the observed line fluxes towards C2 using photoionisation models with the most recent spectral energy distributions available to describe the integrated properties of the stellar cluster. Strong constraints on the geometry based on high spatial resolution observations at different wavelengths -- near-IR (HST and Keck), mid-IR (TIMMI2) and radio (VLA) -- allows us to restrain the ionisation parameters to values logU >= -0.5 dex. This constraint on U lead to two possible solutions for the age and upper mass cutoff of C2: 1) a young (< 4 Myr) cluster with a "non-standard" IMF with a low upper mass cutoff Mup < 50 Msun, and 2) a cluster of ~5-6 Myr with a standard high upper mass cutoff (Mup \~ 100 Msun). Arguments in favour and against these two scenarios are presented. The origin of the [OIV] 25.9 micron emission measured by ISO and the possible presence of an intermediate mass black hole inside C2 are also addressed.

description: ‘Consumer ethnocentrism’ is defined as consumers’ beliefs about the appropriateness or morality of purchasing domestic and foreign-made products. As a consequence of the influx of foodstuffs of dubious origin into Hungary and the increasing number of food scandals, demand for Hungarian foodstuffs of reliable origin has increased. Consumers, however, do not necessarily acquire information from the most reliable sources in the course of purchasing and most of them are not fully aware of what the trademarks featured on the various products mean. Our questionnaire survey sought answers to the questions of how respondents regard Hungarian products and what segments can be distinguished from the aspect of their attitudes concerning Hungarian products. We distinguished four consumer groups – with the aid of cluster analysis – in terms of the factors affecting their choices between Hungarian and imported products when buying foodstuffs, and in terms of their overall attitudes to Hungarian products which appears also in the knowledge of origin labelling.
Antidot tunneling between Quantum Hall liquids with different filling factors

description: We consider tunneling through two point contacts between two edges of Quantum Hall liquids of different filling factors $ν_{0,1}=1/ (2m_{0,1}+1)$ with $m_0-m_1\equiv m>0$. Properties of the antidot formed between the point contacts in the strong-tunneling limit are shown to be very different from the $ν_0 =ν_1$ case, and include vanishing average total current in the two contacts and quasiparticles of charge $e/m$. For $m>1$, quasiparticle tunneling leads to non-trivial $m$-state dynamics of effective flux through the antidot which restores the regular ``electron'' periodicity of the current in flux despite the fractional charge and statistics of quasiparticles.

description: In this paper we have sought to answer three research questions: what was the difference between the agricultural export growth rates of the Visegrád Group countries following the EU accession; how did the multifactor productivity in the countries under study evolve; and could a correlation be observed between the growth rates of the multifactor productivity and of the agricultural exports. The average annual growth rate of the multifactor productivity was highest in Poland, followed by the growth rate in Slovakia, in Hungary and in the Czech Republic. The average annual growth rates of the exports of agricultural raw materials and of the total food economy had identical rankings except for Hungary. The results of the analysis allow the presumption that the different annual average growth rates of the multifactor productivity of agriculture have also influenced the development of the agricultural export performance of the countries under study.

Periodic Coupling inhibits Second-order Consensus on Networks

description: Consensus algorithms on networks have received increasing attention in recent years for various applications ranging from animal flocking to multi-vehicle co-ordination. Building on the established model for second-order consensus of multi-agent networks, we uncover a mechanism inhibiting the formation of collective consensus states via rather small time-periodic coupling modulations. We treat the model in its spectral decomposition and find analytically that for certain intermediate coupling frequencies parametric resonance is induced on a network level -- at odds with the expected emergence of consensus for very short and long coupling time-scales. Our formalism precisely predicts those resonance frequencies and links them to the Laplacian spectrum of the static backbone network. The excitation of the system is furthermore quantified within the theory of parametric resonance, which we extend to the domain of networks with time-periodic couplings.
